Description

The proposed variants of the invention relate to electrical engineering, namely to electrical products for cable power transmission lines.

Supporting elements in cable lines are designed to support cables or cable trays with cables laid in them. The proposed support element is intended primarily to support a cable or bundle of cables without the use of cable trays. If necessary, you can use the proposed support element to support cable trays, pipes and other long objects.

The support element may be the horizontal part of the cable structure (for example, the so-called cable shelf), designed to transfer the weight of the cable to the vertical parts of the cable structure. The support element may also be a separate cable structure (for example, the so-called wall bracket), designed to transfer the weight of the cable directly to the building structure, for example, to a wall or floor, or ceiling. Also, the support element can be a horizontal cable tray crossbar designed to transfer the weight of the cable to the longitudinal support elements of the cable tray, for example, to the ladders of the cable tray. A conventional support element is made of sheet material (usually sheet metal) in the form of a section of a profile (for example, L-shaped or U-shaped, or C-shaped, or closed, or omega-shaped section profile) or in the form of a section of a profile of varying section , i.e. with a change along the supporting element of its transverse dimensions. As a rule, a conventional support element installed in the operating position contains a support wall oriented in the horizontal plane on which the cable is laid, and also contains a supporting wall that provides the stiffness of the support element to a vertical load, i.e. to the weight of the cable and other equipment installed on the support element. The support element is fixed on the building structure or on the vertical support of the cable structure, or on the spar of the cable tray, for example, by fixing the supporting and supporting walls of the support element on it. Also, the support element can be equipped with additional parts (heels, protrusions, etc.) that facilitate the installation of the support element in the cable structure or on the building structure. Under operating conditions, when the cable or cable bundle is horizontal, the support walls of the support member are preferably located in the horizontal plane, and the support walls are preferably located in the vertical planes. The cable is fixed to the support wall of a conventional support element with the help of an additional part - a clamp, staples, clamp, etc.

Known support element disclosed in patent document DE 8801512 (IPC: F16L 3/22; H02B 1/02; H02G 3/04; H05K 7/18; publ. 24.03.1988). The supporting element comprises a supporting wall, a bearing wall located in a vertical plane, and an additional wall in the form of a flanged lower edge of the bearing wall. A heel is welded from one end of the support element. The disadvantage of this support element is that to secure the cables, it is necessary to use additional fasteners, for example, well-known staples or other clamps, clamps. Holes are made to install additional fasteners in the support wall. This complicates the design of the cable line, increases the complexity of laying the cable line.

Known support element disclosed in patent document EP 0332746 (IPC: F16L 3/24; H02G 3/04; H02G 3/26; publ. 09/20/1989). The design of this support element also requires the use of additional fasteners for attaching cables to the support wall of the support element. This complicates the design of the cable line, increases the complexity of laying the cable line.

Known support element disclosed in patent document JP S5484297 (IPC: H02G 3/00; publ. 05.07.1979). Support element in the form of an anchor tire. It contains a support wall, two bearing walls located in vertical planes, and an additional wall connecting the lower edges of the bearing walls. A longitudinal groove is made in the supporting wall. JPS 5484297 discloses the possibility of securing a support element on a ceiling cable structure or on the side members of a cable ladder. The disadvantage of this support element is that to secure the cables, it is necessary to use additional fasteners installed in the groove of the support wall.

Known support element disclosed in patent document RU 2404496 (IPC: H02G 3/04; publ. 20.11.2010). The support element is used as the crossbar of the cable tray. The supporting element is made in the form of a high-quality profile, contains a supporting wall located in the horizontal plane, and two load-bearing walls located in vertical planes. Holes are made in the supporting wall for fastening cables. The disadvantage is that to secure the cables, it is necessary to use additional fasteners - brackets, clamps, clamps, etc.

The above known support elements are analogues of both versions of the proposed support element.

The closest analogue of both versions of the proposed support element is known - the support element disclosed in patent document SU 1387089 (IPC: H02G 3/04; publ. 07.04.1988). The supporting element is made of sheet material, contains two supporting walls located in the horizontal plane and provided with holes, two triangular bearing walls located in vertical planes, and an additional wall connecting the lower edges of the bearing walls. The cross section of the support element is omega-shaped, with height varying along the support element. At one end of the support element, the supporting walls are provided with shaped protrusions, with the help of which the support element can be mounted on a rack of a cable structure equipped with mating shaped openings. The disadvantage of this support element is that to secure the cables, it is necessary to use additional fasteners (brackets, clamps, clamps, etc.) installed in the holes of the supporting walls or attached to the supporting walls using bolts installed in the holes of the supporting walls.

The problem to which the variants of the invention are directed is to reduce the number of cable line parts, to simplify and increase the reliability of securing the cable to a support element made of sheet material and containing at least one support wall intended for laying the cable on it , and at least one load-bearing wall, designed to transfer the load from the supporting wall to the base of the cable structure (on the rack, on the suspension, on the bracket, etc.) or on the building structure (for example, on the wall, on the floor, on the ceiling), or on the spars of the cable tray. Special cases of the proposed variants of the invention are aimed at solving this problem, complicated by the requirements of additional convenience of using the support element as part of private types of cable structures and structures, the requirements of further simplifying the fixation of the cable on the support element, further ensuring the safety of the cable and cable structures of the power cable line, and other requirements , which are clear to the specialist from the following explanations to particular cases of the invention.

Option 1 of the technical solution of the task

This problem is solved in that at least one end section of at least one supporting wall of said supporting element is separated from adjacent walls and bent in the direction of the opposite end section of this supporting wall (with the formation of a groove open at one end supporting element).

The proposed support element is generally similar to the closest analogue in that it is made of sheet material and contains at least one load-bearing wall and at least one support wall. It is understood that the support member has two opposite ends, and each supporting or support wall has two opposite ends. The longitudinal direction of the support element is the direction from one end to the other end.

The proposed support element generally differs from the closest analogue in that at least one end portion of at least one support wall of said support element is separated from adjacent walls and bent in the direction of the opposite end portion of the support wall.

In the first particular case (in an improved implementation of the general case), the proposed support element further differs from the general case in that it comprises a second support wall, wherein at least one end portion of said second support wall is separated from the adjacent walls and bent in the direction of the opposite end portion of said second abutment wall. Preferably, the end sections of both supporting walls are bent in an identical manner, with the formation of two identical "grooves" under the cable, located opposite each other.

In the second particular case, the proposed supporting element further differs from the general case in that both end sections of at least one supporting wall are separated from adjacent walls, while each of these two end sections of the supporting wall is bent in the direction of the opposite end section supporting wall.

In an improved embodiment of the second particular case, the proposed supporting element is further characterized in that it comprises a second supporting wall, wherein both end sections of the second supporting wall are separated from adjacent walls, and each of the two indicated end sections of the second supporting wall is bent in the direction of the opposite end section of the second supporting wall.

In the first refinement, the proposed support element further differs from the second particular case in that the total length of the two bent end sections of the support wall exceeds the length of its middle section by at least one and a half times.

In the second refinement, the proposed support element further differs from the second particular case in that the total length of the two bent end sections of the support wall exceeds the length of its middle section by at least two times; 7, in a separate embodiment, the specified refinement is additionally characterized in that the bent end sections of the supporting wall, when closed to each other, are located relative to the middle section of the supporting wall at an angle of 55 to 65 degrees.

In the development of the first refinement, the proposed support element is further characterized in that the length of one bent end portion of the supporting wall is from one quarter to half the length of its second bent end portion.

In the third particular case, the proposed support element further differs from the general case in that the bent end portions of the support wall are provided with known fastening means. Said fixing means may be made in the form of holes. In a preferred embodiment, the bent end portions of the supporting wall are provided with end pads (bends, flanges), and said holes are made in said end pads. Also, these fastening means can be made in the form of locking elements, for example, buckles, latches, etc. In addition, the proposed support element may additionally be equipped with a removable jumper. It is preferable that the jumper be equipped with reciprocal (or compatible) fastening means and thus provide the opportunity for the bent end sections of the supporting wall to communicate with each other (if both its end sections are bent) or, for example, with fastening means located in the middle section of the supporting wall .

In the fourth particular case, the proposed support element differs from the general case in that it is provided at least at one of its ends with openings made in its bearing walls.

In the fifth particular case, the proposed support element differs from the general case in that it is provided at one of its ends with a heel connected to its supporting walls.

In the sixth particular case, the proposed support element differs from the general case in that it comprises at least one additional wall with holes in its lower part.

In the seventh particular case, the proposed support element differs from the general case in that at least one of its ends is additionally shortened. That is, the part protruding along the support element outward from the bent end portion of the support wall is shortened.

In the eighth particular case, the proposed supporting element differs from the general case in that it contains at least two supporting walls, while the end sections of at least one of the supporting walls are connected to adjacent walls, i.e. not bent, but located in the same plane with its middle section.

The implementation of the support element of sheet material simplifies its manufacture, as it allows the manufacture on a roll mill of, for example, sheet steel. It is also possible to manufacture from, for example, sheet fiberglass or carbon fiber using thermal molding (bending) technologies.

The support wall, located during operation in a plane parallel to the cable (preferably perpendicular to the planes of one or more load-bearing walls), provides a load distribution from the cable to the support element. Under operating conditions, the support wall (more precisely, its portion on which the cable rests) is located in most cases in a horizontal plane.

The bearing wall, located at an angle to the horizontal (preferably located in a vertical plane), provides the rigidity of the support element in relation to the weight load from the cables laid on the support element. Also, the presence of one or more load-bearing walls, located at an angle to the support wall, facilitates the fastening of the support element on the rack of the cable structure, if the support element is used as part of a prefabricated or welded cable structure.

The separation (for example, by cut, dissection) of the end portion of the support wall from adjacent walls (i.e., from the walls of the support element located in a different plane than the plane of the middle sections of the support walls) allows the end portion to be bent towards the opposite end portion.

The end portion of the support wall, bent in the direction of the opposite end portion of the support wall, forms a clip for a cable laid on the middle portion of the support wall.

The technical result is expressed in providing the possibility of using the support element as a cable tie. Thus, the proposed support element contains an integrated clamp; consequently, the need to manufacture or purchase and install a separate clamp on the support element is eliminated, and the production of a complete set of parts for a cable line is simplified. The consequences of inaccurate or incorrect fastening of a separate clamp on the support element, such as the disconnection of the clamp from the support element, which may occur in the case of using known analogues of the proposed support element, are excluded. The formation of ice accumulation or accumulation of dirt between the support wall and the separately installed clamp is prevented, and thus the term of maintaining the operability of the cable line is extended. An additional technical result is expressed in a decrease in the rigidity of the end part of the support element to bend in the horizontal plane due to the exclusion of the end portion of the support wall from it by bending. The decrease in spatial rigidity of the end part of the support element contributes to the absorption of the mechanical energy of the deformation of the support element in the event of a short circuit in the cable line, accompanied by a surge of magnetic interaction between the cables clamped in the clamp of the support element, and thus contributes to the preservation of cable structures and cable sheaths in the case of short short circuits.

The second supporting wall, the end portion of which is separated from adjacent walls and bent in the direction of the opposite end portion of the specified second supporting wall, makes it possible to use the supporting element as a supporting element with a double integrated cable tie to secure one cable or bundle of cables. The technical result is expressed in an increase in the damping qualities of the support element under conditions of a short circuit of the cable line, since two integrated clamps are located on different support walls, the mutual position of which can slightly change under the influence of extraneous forces, with the absorption of part of the energy of the influence of extraneous forces. Thus, in this improved implementation of the proposed support element, a “game” of two integrated cable clamps holding the bundle of cables is shown, compared with one double-width clamp mounted on a known support element, or compared with one integrated double-width clamp that can be provided the proposed supporting element in the presence of one supporting wall with double width.

The two end sections of the support wall, bent towards each other, form a seat in the form of a "saddle" for a cable laid on the middle section of the support wall. After laying the cable, the free ends of the bent sections are connected to each other and fixed, with the formation of a clamp around the cable. It is clear that the supporting element must be made of a sufficiently pliable sheet material that allows the installer to dilute and reduce the bent ends of the supporting wall. The fastening of the connected ends can be performed, for example, as a seam connection (if the support element is made of steel, and if the length of the bent end sections is sufficient to overlap their free ends with each other). It is preferable to fasten the free ends of the bent sections to each other using a detachable connection, for example, a bolted connection. For this, the bent sections can be additionally equipped with holes for the bolt, or with slots, loops, etc.

The second supporting wall, the end sections of which are bent towards each other, makes it possible to use it as a second integrated collar of the proposed supporting element. The technical result is expressed in an increase in the damping qualities of the support element under conditions of a short circuit of the cable line, since two integrated clamps are located on different walls, the mutual position of which can slightly change under the influence of extraneous forces, with the absorption of a part of the energy of the influence of extraneous forces. Thus, in this improved embodiment of the particular case of the proposed support element, a “game” of two integrated clamps holding the bundle of cables in the double “saddle” is shown, compared with a single double-width clamp mounted on the support element.

The total length of the two bent end sections of the support wall, exceeding the length of its middle section by at least one and a half times, makes it possible to directly close the free ends of the bent sections with each other with the formation of a closed loop around the cable laid on the support wall (of course, with the restriction on the diameter of the cable, which can easily be taken into account by a specialist). As a result of this, the need to “build up” the loop of the integrated clamp by improvised means is eliminated. If the total length of the two bent end sections of the supporting wall is twice the length of its middle section, it is possible to build an integrated clamp, for example, in the form of an equilateral triangle, with the ends of the bent end sections of the supporting wall closed to each other. With the total length of the two bent end sections of the supporting wall exceeding the length of its middle section by 3.14 times, it is possible to build an integrated clamp in the form of a semicircle with the ends of the bent end sections of the supporting wall closed to each other.

If the bent end sections of the support wall, when closed to each other, are located in relation to the middle section of the support wall at an angle of 55 to 65 degrees, it is possible to fix three power cables to the support element in the triangle configuration known to the person skilled in the art, which is optimal for power cable lines. This is an additional technical result of this refinement.

If the length of one bent end section of the supporting wall is from one quarter to half the length of its second bent end section, it is possible to place the connection point of the bent sections to each other on the side of the integrated clamp at a lower height than the height of the middle of the loop of the integrated clamp . This achieves a decrease in the vertical dimension of the integrated clamp of the proposed support element while maintaining the area of its opening, in particular, if the bent end sections of the support wall are equipped with end pads (flanges) and are connected not overlapping, but end-to-end. In addition, the location of the junction of the bent sections with each other on the side of the integrated clamp facilitates the work of the installer when laying and securing the cable on the support element, if other objects are located above the support element, for example, the support element of the next tier of the cable structure.

The supply of the bent end sections of the supporting wall with known fastening means facilitates the work of the installer, as it eliminates the need for additional operations at the installation site of the cable line, for example, drilling or punching holes. The holes in the bent end sections facilitate their fastening with another section of the support wall or with a removable jumper, because provide the ability to use for fastening standard parts - bolts, nuts, studs.

End pads with openings of bent end sections of the supporting wall provide the ability to connect them end-to-end with each other, or with the surface of a non-bent (for example, middle) section of the supporting wall. Such a butt joint facilitates the work of the installer and eliminates damage to the cable with bolts, nuts or a wrench.

Fasteners in the form of locking elements accelerate the fastening of the cable in the integrated clamp, since they do not require the use of bolted connections.

The removable jumper allows you to increase the opening of the integrated clamp by installing it between the free ends of the bent end sections of the supporting wall, for example, between their end sites. If the integrated clamp is formed by one bent end portion of the supporting wall, a removable jumper can be installed between the non-bent portion of the supporting wall and the free end of its bent portion. Also, a jumper (preferably shaped) can be used as a liner that prevents deformation of the cable sheaths, for example, if several cables are fixed in the integrated clamp.

Holes made in the bearing walls at the end of the support element provide bolt-fastening of this end of the support element to the cable structure, for example, to a cable rack, or, for example, to a cable tray spar. In order to facilitate fastening on a cable tray spar or on embedded studs of a building structure, end pads (bends) in which these holes are located can be made at the ends of the bearing walls.

A heel connected (for example, by welding or rivets, or detachable connection) with the bearing walls of the support element at one of its ends, can be used to fix the support element to the wall, or, for example, on the side member of the cable tray.

A wall with holes located in the lower part of the support element provides the ability to install the support element on flat surfaces (wall, floor, ceiling) using bolted joints, studs, and crutches.

The shortening of the end of the support element provides a reduction in the transverse dimension of the cable line or cable tray in which the proposed support element is used. This simplifies the installation and maintenance of the cable line in cramped rooms - in galleries, in production rooms. If the support element is made of sheet metal by cutting and bending, then shortening is preferably performed at the stage of cutting (cutting) of the workpiece with subsequent bending.

The end sections of one of the supporting walls connected to adjacent walls, i.e. located in the same plane with its middle section (which implies the absence of an integrated clamp of this supporting wall), can be used to install additional known cable clamps, clamps, brackets. This makes it possible to secure additional cables to the support element, for example, when upgrading the cable line.

Option 2 technical solutions to the problem

This problem is solved in that at least one end portion of at least one abutment wall is separated from adjacent walls, wherein said end portion is located as a continuation of the middle portion of the specified abutment wall along the proposed support element made of sheet material and containing at least one supporting wall and at least one supporting wall.

The proposed support element is generally similar to the closest analogue in that it is made of sheet material and contains at least one load-bearing wall and at least one support wall.

The proposed support element generally differs from the closest analogue in that at least one end portion of at least one support wall is separated from adjacent walls, wherein said end portion is located as a continuation of the middle portion of the specified support wall along supporting element.

In the first particular case, the support element differs from the general case in that the said end sections of the support wall, separated from the adjacent walls, are provided with fastening means at their free ends.

In clarifying the first particular case, the support element is further characterized in that said fastening means are made in the form of holes.

In the second particular case, the support element differs from the general case in that, at least at one of its ends, holes are made in the bearing walls.

In the third particular case, the support element differs from the general case in that it is provided at one of its ends with a heel connected to its supporting walls.

In the fourth particular case, the support element differs from the general case in that it comprises at least one additional wall with holes in its lower part.

In the fifth particular case, the support element differs from the general case in that at least at one end of the support element, at least its load-bearing walls are additionally shortened relative to said end portion of said support wall located as a continuation of the middle portion of said support wall along supporting element.

The implementation of the support element of sheet material simplifies its manufacture, as it allows the manufacture on a roll mill of, for example, sheet steel. It is also possible to manufacture from, for example, sheet fiberglass or carbon fiber using thermal molding (bending) technologies.

The support wall, located during operation in a plane parallel to the cable (preferably perpendicular to the planes of one or more load-bearing walls), provides a load distribution from the cable to the support element. Under operating conditions, the support wall (more precisely, its portion on which the cable rests) is located in most cases in a horizontal plane.

The bearing wall, located at an angle to the horizontal (preferably located in a vertical plane), provides the rigidity of the support element in relation to the weight load from the cables laid on the support element. Also, the presence of one or more load-bearing walls, located at an angle to the support wall, facilitates the fastening of the support element on the rack of the cable structure, if the support element is used as part of a prefabricated or welded cable structure.

The separation (for example, by cut, dissection) of the end portion of the support wall from adjacent walls (i.e., from the walls of the support element, located at an angle to the plane of the support walls) allows the user to subsequently bend one end section or each of both end sections in the direction the opposite end portion of the support wall to obtain the first variant of the proposed support element, equipped with an integrated clamp for fixing the cable or cable bundle on the support wall of the support wow element.

The location of the specified end section as a continuation of the middle section of the specified supporting wall along the supporting element limits one of the transverse dimensions of the supporting element, and thus saves occupied space when storing or transporting batches of supporting elements. The location of the end portion of the support wall as an extension of the middle portion of the support wall along the support element is understood as the location in the same plane as the middle portion of the support wall or as another arrangement not accompanied by an increase in the size of the support element. For example, we allow a slight limb of the end portion of the supporting wall in any direction, if this facilitates access to the fasteners during installation of the second version of the proposed support element on the cable structure, and does not complicate the storage and transportation of batches of the second version of the proposed support element.

The proposal of the second technical solution is due to the fact that the bending of the end sections of the supporting wall can be performed by the consumer at the installation site of the cable line, including after laying the cable on the middle section of the support wall. In this case, the manufacturer of the supporting element only separates the end sections of the supporting wall by cutting (cutting) from the adjacent walls, but leaves them in the same plane as the middle section of the supporting wall, as a result of which an additional technical result is achieved, namely, the convenience of storage and transportation of the proposed supporting elements is improved (compared with the first version of the proposed support element, supplied to the consumer with pre-bent towards each other end sections about porn wall). It should also be noted that the second variant of the proposed supporting element can be obtained from the first variant of the supporting element by reverse extension of the end sections of the supporting walls; as a result, the first version of the support element is brought into a state convenient for transportation or storage. In addition, it is further possible to use the second version of the support element as a conventional known support element, if the consumer uses separate removable clamps for fixing the cable.

Thus, the second variant of the proposed support element contains an integrated clamp in high readiness for storage and transportation. The technical result of the second embodiment, common with the first embodiment, is expressed in providing the possibility of using the support element as a cable clamp. Consequently, the need to manufacture or purchase and install a separate clamp on the support element is eliminated, and the production of a complete set of parts for a cable line is simplified. The consequences of inaccurate or incorrect fastening of a separate clamp on the support element, such as the disconnection of the clamp from the support element, which may occur in the case of using known analogues of the proposed support element, are excluded. The formation of ice accumulation or accumulation of dirt between the support wall and the separately installed clamp is prevented, and thus the term of maintaining the operability of the cable line is extended. Another additional technical result is achieved by separating the end portion of the supporting wall from adjacent walls. This increases the mobility of the support element when securing it with this end on the cable structure, i.e. improves the damping qualities of the support element with respect to peak mechanical loads arising from a short circuit in the power cable line. Bringing the integrated clamp to the operating position (i.e., bending the separated end portion of the support wall in the direction of the opposite end portion) further reduces the rigidity of the end part of the support element to bend in the horizontal plane due to the exclusion of the end portion of the support wall by bending. Thus, an increase in the safety of cable structures and cable sheaths in the event of a short circuit is achieved. If the supporting element is made of sheet metal, the subsequent bending of the end sections of the supporting walls is done mechanically, for example, manually. If the supporting element is made of sheet plastic, the subsequent bending of the end sections of the supporting walls is carried out using a heating tool (hair dryer).

Providing the free ends of the separated end sections of the supporting wall with known fixing means facilitates the work of the installer, as it eliminates the need for additional operations at the cable line installation site, for example, drilling or punching holes. The holes available in the separated end sections as the indicated fastening means facilitate their fastening with another section of the support wall or with a removable jumper, because provide the ability to use for fastening standard parts - bolts, nuts, studs.

Holes made in the bearing walls at the end of the support element provide bolt-fastening of this end of the support element to the cable structure, for example, to a cable rack, or, for example, to a cable tray spar. In order to facilitate fastening on a cable tray spar or on embedded studs of a building structure, end pads (bends) in which these holes are located can be made at the ends of the bearing walls.

A heel connected (for example, by welding or rivets, or detachable connection) with the bearing walls of the support element at one of its ends, can be used to fix the support element to the wall, or, for example, on the side member of the cable tray.

A wall with holes located in the lower part of the support element provides the ability to install the support element on flat surfaces (wall, floor, ceiling) using bolted joints, studs, and crutches.

The shortening of the bearing walls at least at one end of the support element relative to the length of the specified end section (i.e., separated from adjacent walls) located as a continuation of the middle section of the specified support wall along the support element, reduces the transverse dimension of the cable line or cable tray in which the proposed support element is used as a support element with an integrated clamp (i.e., provided that the specified end portion of the support wall is bent in a different direction its second end portion). This simplifies the installation and maintenance of the cable line in cramped rooms - in galleries, in production rooms. If the support element is made of sheet metal by cutting and bending, then the shortening is preferably performed at the stage of cutting (cutting) of the workpiece.
