{FIXING DEVICE OF SWITCHGEAR FOR UNINTERRUPTIBLE CONSTRUCTION}

The present invention relates to a fixing device for a switch for uninterruptible power construction, and more specifically, to a fixing device for a switch for uninterruptible power construction for stably fixing the switch for uninterruptible power construction on a utility pole during overhead power distribution construction.

Typically, electricity is transmitted from power plants to substations via transmission lines such as transmission towers, and after going through several stages of transformation, it is supplied to general consumers (households) along distribution lines on utility poles.

At construction sites for overhead power distribution, an uninterruptible power supply switch, which is attached to a concrete utility pole, is an essential piece of equipment used to supply uninterrupted power.

The uninterruptible power switch is a device that bypasses the construction section so that power supply is maintained even when the construction section of the overhead power distribution is blocked during replacement work, etc. on the overhead power distribution.

The uninterruptible power switch is installed between two bypass cables connected to overhead power distribution, configuring the circuits in parallel and creating a diagonal working section to provide a safe working environment for workers. As the direct live-line method is being abolished in the overhead power distribution construction field, its frequency of use is increasing.

The uninterruptible power switch is installed by wrapping a chain around a utility pole, inserting the chain into the chain fixing part, and then tightening the butterfly nut to secure it to the utility pole.

Even when the uninterruptible power switch is installed on a utility pole, there is a problem in that if the fixing butterfly nut is loosened, the fixing force of the chain is lost, and even with a slight impact, the chain may come off and slip and fall on the utility pole, causing safety accidents such as equipment damage and injuries to workers and passersby.

To solve these problems, tie bands having a threaded connection and a corresponding threaded engagement portion have been proposed in the past, but the phenomenon of dropping frequently occurred due to the threaded connection and the threaded engagement portion gradually loosening.

Therefore, there is a need to improve the fixed equipment for uninterruptible power switches so that they can be stably installed on utility poles during overhead power distribution construction.

The background technology of the present invention is disclosed in Republic of Korea Utility Model Registration No. 20-0303378 (registered on January 24, 2003, title of the invention: Agricultural distribution box tie band installed in Jeonju).

In the present invention, the fastening member may include a rotary connecting body axially connected to the connecting member, a first fastening member axially connected to the rotary connecting body and fastened to the long portion, and a second fastening member connected to the first fastening member by tightening or loosening.

In the present invention, the fastening member can rotate left and right based on the longitudinal direction of the bending end, and the first fastening member can rotate up and down.

In the present invention, the fixing hook portion may be provided with a fixing frame that is axially connected to the base body and a pair of fixing members that are arranged on the fixing frame and protrude toward the uninterruptible power construction switch.

In the present invention, the uninterruptible power construction switch has a fixed frame, and the hanging member has a plurality of guide parts formed so that the fixed frame is secured, and the guide parts can have a guide surface inclined toward the inside of the hanging member and a guide groove extended from the guide surface so that a part of the fixed frame is secured.

In the present invention, a plurality of reinforcing members connecting the base body and the female member are formed on the outer side of the body portion, and the reinforcing members can be arranged spaced apart from each other in parallel along the longitudinal direction of the body portion.

As illustrated in FIGS. 1 to 4, the fixing device (100) of the uninterruptible power construction switch according to the present invention includes a body part (110), a fastening part (130), and a fixing hook part (150).

The body part (110) is provided with a base body (111) and a female member (113) so that the spacing can be adjusted and installed to surround a telephone pole (70), and a plurality of reinforcing members (110a) are formed to connect the outer base body (111) and the female member (113).

The base body (111) has a connecting member (111a) formed to extend in the longitudinal direction, and is provided as a pair by being axially connected to the connecting member (150a) formed at both ends of the fixing member (150) by a rotating shaft (10) so as to be rotatable, and a handle (111c) is formed on each outer side so that the gap between them is adjusted via the rotating shaft (10).

The body part (110) implements the rotational linkage between the base body (111) and the female member (113) through the rotational shaft (10) that is axially connected to the base body (111) and the fixing member (150), and can repeat the operation of increasing or decreasing the gap by using the handle (111c) formed on the outside of the base body (111).

The base body (111) has a mounting pad (111b) formed with a contact surface (not shown) corresponding to the shape of the telephone pole (70) so as to be in close contact with the perimeter of the telephone pole (70) on the inside, and the mounting pad (111b) is detachably provided on the inside of the base body (111) so as to be managed for maintenance and repair.

The female member (113) is formed by extending from a pair of base bodies (111) and is provided with a bend end (113a), a slot (113b), and a connecting portion (113c) so that the gap can be adjusted according to each rotation of the base body (111).

The folded end (113a) extends from the end of the female member (113) and is folded toward the inside of the body part (110) to reinforce the end of the female member (113) so that it is implemented as a double layer, and the body part (110) is implemented so that it is adjusted at a certain interval by combining with the fastening part (130).

The opening (113b) is formed through one of the bending ends (113a) and is fastened to the fastening end (130) by the operation of the fastening end (130), and the inner and outer parts are connected to each other on the bending end (113a) to form an upper curved part (113b-1) and a lower curved part (113b-2).

The connecting portion (113c) is formed on another one of the bending ends (113a) and is arranged on the same line as the longitudinal portion (113b) based on the transverse direction of the female member (113), and is provided as a pair at the upper and lower portions of the fastening portion (130) based on the longitudinal direction of the female member (113) in response to the arrangement of the fastening portion (130).

The fastening member (130) is rotatably connected to the body part (110) and includes a rotatably connecting member (131), a first fastening member (133), and a second fastening member (135) so that the body part (110) is fixed at a certain interval.

The rotary connector (131) is positioned penetrating the folded end (113a) of the female member (113) and is axially connected to the connecting hole (113c) of the female member (113) through the rotation shaft (30), and can rotate left and right based on the longitudinal direction of the female member (113) within the folded end (113a).

The first fastening member (133) is axially connected to the rotary connecting body (131) through the rotary shaft (50) and is inserted and connected into the long section (113b) of the female member (113). Based on a cylindrical shape extended in one direction, a connecting hole (133a) that is axially connected to the rotary connecting body (131) is formed at one end, and a screw thread (133b) that is connected to the second fastening member (135) is formed at the other end.

The second fastening member (135) is formed with a hollow hole (not shown) having screw threads (135a) corresponding to the screw threads (133b) of the first fastening member (133) so that it can be fastened or loosened to the first fastening member (133), and a ring member (135b) is formed so that it can be easily fastened and separated from the first fastening member (133) by any rotational force.

The fixing hook (150) is rotatably connected to the base body (111) of the body part (110) through the rotation shaft (10), and when the gap of the body part (110) is fixed by the fastening part (130), it is provided with a fixing frame (151) and a hooking member (153) so as to be connected to the uninterruptible power construction switch (200).

The fixing frame (151) has connecting holes (150a) formed at both ends, a rotation shaft (10) inserted into the connecting holes (150a) and axially connected to the base body (111), and is formed such that the two ends are inclined toward the center in the longitudinal direction.

Since the center of the fixing frame (151) is formed to be relatively inclined in the longitudinal direction, the gap adjustment operation of the body part (110) centered on the fixing hook part (150) is performed flexibly, so that the phenomenon of breakage and leakage that may occur in the center of the fixing frame (151) due to the bidirectional rotation of the body part (110) can be prevented.

The hanging members (153) are arranged in pairs extending along the longitudinal direction of the fixing frame (151) so that one side protrudes toward the uninterruptible construction switch (200), and a plurality of guide parts (153a) are formed so that the fixed frame (210) equipped in the uninterruptible construction switch (200) is fixed.

A hanging member (153) is formed at both ends of the fixing frame (151), and a pair of connecting holes (150a) extending from one end of the hanging member (153) are spaced apart from each other and a rotational axis (10) for rotation of the base body (111) and the fixing frame (151) is inserted and connected.

The guide part (153a) has a guide surface (153a-1) that is inclined toward the inside of the hanging member (153) and a guide groove (153a-2) that extends from the guide surface (153a-1) and into which a part of the fixed frame (210) of the uninterruptible power construction switch (200) is secured.

Since the guide surface (153a-1) of the guide part (153a) is inclined and communicates with the guide groove (153a-2), the fixed frame (210) of the uninterruptible construction switch (200) is guided to the guide groove (153a-2), so that the uninterruptible construction switch (200) can be installed quickly and reliably on the fixing frame (151) even in a night-time work environment.

In the configuration of the fixing device (100) of the switch for uninterruptible construction use according to the present invention described above, the fixing device (100) of the switch for uninterruptible construction use may be configured with a body part (110), a fastening part (130), and a fixing hook part (150) made of a durable metal.

The mounting pad (111b) of the base body (111) may be composed of an insulating material such as a thermoplastic elastomer (TPE) with insulating performance for easy handling at electrical equipment-related work sites.

Thermoplastic elastomers have both the properties of rubber and plastic, but they are harder than rubber and have superior resilience than plastic, so when there is contact or separation between the electric pole (70) and the mounting pad (111b), they protect the outside of the electric pole (70) and the inside of the base body (111), while also providing convenient handling.

The settling pad (111b) can be formed by using an insulating coating method using an insulating material such as silicone, rubber, and synthetic resin, and can be manufactured by molding using an insert casting method by pouring an insulating material such as silicone, rubber, and synthetic resin into a solvent using a mold (molding mold).

The material of the anchoring pad (111b) can be prepared using materials such as silicone, rubber, and synthetic resin for insulation, and is not limited to a specific material. If it is a material that has excellent anti-slip properties while protecting the outside of the telephone pole (70) and the inside of the base body (111) when in contact with the telephone pole (70), it can be implemented in various ways.

On the outside of the body part (110), a plurality of reinforcing members (110a) are formed to connect the base body (111) and the female member (113) and prevent damage such as breakage and leakage that may occur between the base body (111) and the female member (113) according to the gap adjustment operation of the body part (110).

The reinforcing members (110a) are spaced apart from each other and arranged parallel to each other along the longitudinal direction of the body part (110), and are formed to be inclined from the base body (111) to the female member (113), so that the center is relatively thicker than the two ends.

The fixing device (100) of the uninterruptible power construction switch is formed by a pair of body parts (110) having a fixed spacing through a fastening part (130) to form a receiving space (not shown) for wrapping around a telephone pole (70), and a pair of fixing pads (111b) are arranged facing each other on the receiving space so that a pair of fixing pads (111b) and a handle (111c) are arranged on the same line.

The fastener (113b) has an upper curved portion (113b-1) and a lower curved portion (113b-2) formed by connecting the inner and outer portions on the folded portion (113a), and since the upper curved portion (113b-1) and the lower curved portion (113b-2) are connected to each other, damage to the folded portion (113a) of the female member (113) that may occur during the joining process of the first fastening member (133) and the second fastening member (135) can be minimized.

Since the fastening part (113b) has an upper curved part (113b-1) and a lower curved part (113b-2), the fastening position of the fastening part (130) can be flexibly adjusted to respond to the situation of the work site where the utility pole (70) is installed, thereby preventing damage to the equipment, and thus enabling the use and preservation period to be maintained for a long time.

The fixing device (100) of the uninterruptible power construction switch according to the present invention is provided with a pair of fastening parts (130) along the longitudinal direction of the female member (113), but at least one or more may be arranged to implement spacing adjustment and fixation of the body part (110), and the number of fastening parts (130) arranged is not limited to one.

As shown in Fig. 8, the fixing device (100) of the uninterruptible power construction switch rotates up and down through the rotation axis (50) with the fastening part (130) as the standard in the longitudinal direction of the female member (113).

The fastening member (130) is connected to the first fastening member (133) by the rotational connecting body (131) and the rotational shaft (50) and rotates up and down based on the longitudinal direction of the female member (113), and the rotational connecting body (131) is connected to the connecting hole (113c) of the female member (113) by the rotational shaft (30) and cannot be linked with the up and down operation of the first fastening member (133).

Figure 9 is a drawing showing an application example in which a fixing device for a switch for uninterruptible power construction according to an embodiment of the present invention is installed on a utility pole. However, a utility pole applicable during overhead power distribution construction is described as an example.

The fixing hook (150) is rotatably connected to the base body (111) of the body part (110) through the rotation shaft (10), and when the gap of the body part (110) is fixed by the fastening part (130), it is provided with a fixing frame (151) and a hooking member (153) so as to be connected to the uninterruptible power construction switch (200).

As shown in Fig. 9, at a work site where overhead power distribution work is required, a cable (not shown) placed on a utility pole (70) is installed to protect the cable, and the fixing device (100) of the uninterruptible power construction switch contacts the fixing pad (111b) corresponding to the circumference of the utility pole (70) by the spacing adjustment operation of the body part (110).

The fixing device (100) of the uninterruptible power construction switch can fix the inner side of the female member (113) to the outer side of the inlet pipe (90) while fixing the gap of the body part (110) through the tightening and loosening operation of the fastening part (130).
