Abstract

The utility model relates to a bus duct angle iron hanging bracket, and belongs to the technical field of electrical conveying facilities. The bus duct angle iron hanging bracket comprises a pair of angle iron supports, and a pair of hanging brackets, wherein each hanging bracket is formed by welding a base plate and a hanging plate which is vertical to the base plate; the upper part of each angle iron support is provided with a column of through holes which are distributed at intervals in a vertical direction, expansion bolt through holes are made in the base plates, and at least a horizontal groove and an inclined curved groove are distributed in the hanging plate in an up and down manner. In such a way, stepless adjustment for the inclination degree is achieved, and the requirement for mounting a bus duct in a horizontal manner is fulfilled in any conditions with inclined ceilings by connecting with an angle iron support through hole which corresponds to the hanging plate horizontal groove or the inclined curved groove, and properly adjusting a relative position in the curved groove, of a fastening element which goes through the through hole according the inclination degree of the ceiling. The bus duct angle iron hanging bracket is convenient to use.

Description

A kind of bus duct angle steel suspension bracket

Technical field

The utility model relates to a kind of suspension bracket, and especially a kind of bus duct angle steel suspension bracket, belongs to technical field of electric power transmission facility.

Background technology

The bus duct transmitting electric power often need to be lifted under the ceiling of building, and the suspension bracket being welded by substrate and perpendicular boatswain chair is the important component of realizing the unsettled lifting of bus duct.When installation, substrate is fixed on building ceiling with setscrew, then by selecting the suitable screw in vertical round on boatswain chair or angle bar frame, is connected with the angle bar frame upper end that lower end is hung bus duct by bolt.But while running into the building ceiling of non-standard state, the restriction that is subject to above-mentioned prior art to have level to regulate, usually cannot guarantee bus duct level, have to on-the-spot repair suspension bracket or angle bar frame, make troubles to the installation of bus duct.

Utility model content

The purpose of this utility model is: the shortcoming existing for above-mentioned prior art, proposes a kind of no matter how ceiling tilts all can meet the bus duct angle steel suspension bracket of the horizontal installation requirement of bus duct without on-the-spot repair.

In order to reach above object, bus duct angle steel suspension bracket of the present utility model comprises pair of horns steel bracket, and a pair of suspension bracket being welded by substrate and perpendicular boatswain chair, described angle bar frame top has the through hole that at least one row vertical spacing distributes, on described substrate, be shaped with expansion bolt perforation, described boatswain chair is shaped with at least one level trough of distribution up and down and the curved groove of an inclination.

Like this, can realize the step-less adjustment of gradient, when lifting bus duct, according to the gradient of ceiling, select corresponding with boatswain chair level trough and curved groove position respectively angle bar frame through hole, and suitably regulate securing member through the through hole relative position in curved groove, and can meet the requirement that various inclination ceiling situation Down Highway groove levels are installed, very convenient.

Further, top two vertical surface of described angle bar frame have respectively the uniform vertical extension waist through hole of a row vertical spacing.

Further again, the upper and lower distribution mutual dislocation of two row waist through hole.

Further again, the lower end of described angle bar frame and vertical suspension rod are connected, and the bottom of described suspension rod has external screw thread, is connected by binding nut and cross-arm.

Also further, described curved groove is circular curve groove, and described circular curve groove is got the arc section of corresponding flat rectangular coordinate system the second quadrant.

Below in conjunction with accompanying drawing, the utility model is further described.

Embodiment

Embodiment mono-

The bus duct angle steel suspension bracket of the present embodiment as depicted in figs. 1 and 2, comprises a pair of vertical angle bar frame 5, and a pair of suspension bracket being welded by substrate 2 and perpendicular boatswain chair 3.Top two vertical surface of angle bar frame 5 have respectively the uniform vertical extension waist through hole of a row vertical spacing, the distribution mutual dislocation up and down of two row waist through hole, the i.e. waist through hole interval of corresponding another row of waist through hole in row, thereby suitably select two vertical surface, can make the upper-lower position of following securing member 4 in through hole not be subject to the restriction at interval.The lower end of angle bar frame 5 and vertical suspension rod 9 are connected, and the bottom of suspension rod 9 has external screw thread, are connected respectively by the two ends of binding nut and cross-arm 6.

The structure of suspension bracket as shown in Figure 3, is shaped with two kidney-shaped expansion bolt perforation 2-1 on substrate 2, the boatswain chair of welding is shaped with the circular curve groove 3-1 of a upper and lower distribution level trough 3-2 and an inclination with it.This circular curve groove is got the arc section of corresponding flat rectangular coordinate system the second quadrant.This circular curve has the become characteristic of low wedging of securing member relative position, therefore, in the time that bus duct deadweight makes securing member 4 be tending towards declining, can eliminate gap, makes its wedging in groove, guarantees after fastening can not be subjected to displacement because of factors such as vibrations.

When installation, bus duct is fixed on cross-arm 6 by clamp 7 and bolt 8, because suspension rod 9 lower ends are connected with cross-arm 6 by binding nut, therefore can select the favorably situated vertical surface of angle bar frame 5 waist through hole, select again corresponding with boatswain chair level trough 3-2 and curved groove 3-1 position respectively angle bar frame through hole, and take the circumstances into consideration suitably to regulate securing member 4 through the through hole relative position in curved groove, can meet the requirement (referring to Fig. 4) that various inclination ceiling situation Down Highway groove levels are installed.

Facts have proved, the bus duct angle steel suspension bracket tool of the present embodiment has the following advantages:

1) make simply, install easy to adjust;

2) alternative is good, has conscientiously realized the step-less adjustment of gradient;

3) setting of circular curve has securing member relative position and more has wedging self-locking performance under more.

Characteristic, contribute to keep the firm of bus duct after installing.

In addition to the implementation, the utility model can also have other execution modes.For example, curved groove can be also the straight trough tilting or be made up of other curve; For another example, level trough can change with the relative upper-lower position of curved groove, etc.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
