[0002] In order to ensure the stability and safety of the bus duct when it is installed vertically, spring supports are usually installed on the left and right sides of the bus duct. Two support beams are respectively arranged on the front and rear sides of the bus duct body to limit the front and rear positions of the bus duct. Two spring supports are fixed on the two support beams to support the bus duct on the left and right. The spring supports can absorb vibrations and play a damping role at the same time, which is conducive to the stable operation of the bus duct and prolongs its service life.

[0003] The existing spring support is generally composed of two bolts each equipped with a reset spring and a bracket arranged on the top of the two bolts and fixedly connected to the bus duct. Since the reset spring is directly mounted on the outside of the bolt, the bolt has no other supporting structure except the connection point with the support beam and the bracket, and the bolt rod is prone to bending and deformation. Therefore, the applicant has designed a seismic-resistant bracket for the bus duct to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a seismic-resistant bracket for a bus duct, which solves the problem that the current spring supporters mostly sleeve the spring bracket on the outside of the bolt, which easily causes the bolt rod to bend and deform later.

[0007] The elastic connector includes a first bolt for connecting the support frame and the fixing frame, and a return spring and a column which are both mounted on the outside of the first bolt and are distributed in the upper and lower directions. The outer side of the column is welded with a first support and a second support which are respectively distributed along the length direction of the first channel steel and the length direction of the second channel steel. The first support and the second support are respectively assembled on the first support and the second support by the second bolt.

[0008] The two support frames are symmetrically distributed front and rear, and first positioning holes for first bolts to pass through and install are opened on the left and right sides of the top of the two first channel steels, and the four first positioning holes are distributed in a rectangular array. The two fixing frames are symmetrically distributed left and right, and second positioning holes for first bolts to pass through and install are opened on the front and rear sides of the bottom of the two fixing frames, and the four second positioning holes are coaxially distributed with the four first positioning holes.

[0009] Preferably, both sides of the top of the first channel steel and the top of the second channel steel are provided with strip holes distributed along the length direction of both, and the strip holes are adapted to the second bolts.

[0010] Preferably, a limiting groove for accommodating the bottom end of the return spring is formed on the top of the column, and the limiting groove is coaxially distributed with the column.

[0011] Preferably, two L-shaped clamping plates are assembled on the inner side of the fixing frame through the third bolt, and the two clamping plates are symmetrically distributed and respectively arranged on the front and rear sides of the inner side of the fixing frame. The inner side of the fixing frame is provided with an installation groove for accommodating the head of the third bolt and distributed along the length direction of the fixing frame. Beneficial Effects

[0027] See also Figure 1-4 The utility model provides a technical solution: an anti-seismic bracket for a bus duct, comprising a bus duct body 100 erected in a vertical direction and two support frames 200 respectively arranged on the front and rear sides of the bus duct body 100, and two fixing frames 400 erected above the two support frames 200 through four elastic connectors 300, the two fixing frames 400 are assembled on the bus duct body 100, the support frame 200 comprises a first channel steel 210 and two second channel steels 220 respectively welded vertically to the left and right sides of the outer side of the first channel steel 210, the elastic connector 300 comprises a first bolt 310 for connecting the support frame 200 and the fixing frame 400, and a reset spring 320 and a column 330 both of which are sleeved on the outside of the first bolt 310 and distributed in the upper and lower directions, and the outer side of the column 330 The first support 340 and the second support 350 are welded on the side and are distributed along the length direction of the first channel steel 210 and the length direction of the second channel steel 220 respectively. The first support 340 and the second support 350 are respectively assembled on the first support 340 and the second support 350 by the second bolt 360. The two support frames 200 are symmetrically distributed front and rear. The left and right sides of the tops of the two first channel steels 210 are provided with first positioning holes 230 for the first bolts 310 to pass through and install. The four first positioning holes 230 are distributed in a rectangular array. The two fixing frames 400 are symmetrically distributed left and right. The front and rear sides of the bottoms of the two fixing frames 400 are provided with second positioning holes 410 for the first bolts 310 to pass through and install. The four second positioning holes 410 are coaxially distributed with the four first positioning holes 230, respectively.

[0028] Based on the above-mentioned structure, the bus duct seismic support is composed of a bus duct body 100, two support frames 200, two fixing frames 400 and four elastic connectors 300, wherein the bus duct body 100 is erected in the vertical direction, the two fixing frames 400 are symmetrically distributed on the left and right and assembled on the bus duct body 100, the two support frames 200 are distributed front and back and are attached to the bus duct body 100, and the four elastic connectors 300 are divided into two groups and are fixedly installed on the two support frames 200 and provide elastic support for the two fixing frames 400. Specifically, during the installation process, the operator first fixes the two support frames 200 on the building wall. At the same time, the two support frames 200 are respectively fitted with the front and rear sides of the bus duct body 100. Then, the operator sequentially assembles four elastic connectors 300 on the two support frames 200. The four elastic connectors 300 are divided into two groups and are respectively installed on the two support frames 200. For the installation of the elastic connectors 300, the operator first connects the column 330 with the first positioning hole 230, and then, respectively, with the help of two second positioning holes 230. The two bolts 360 respectively fix the first support 340 and the second support 350 on the first channel steel 210 and the second channel steel 220. Next, the operator passes the screw of the first bolt 310 through the first positioning hole 230 and the column 330 in turn and sets the reset spring 320 on the outside of the screw. Finally, the operator passes the top of the screw through the corresponding second positioning hole 410 on the fixing frame 400 and screws on the nut. After the two fixing frames 400 are installed on the top of the four elastic connectors 300, the operator can adjust the fixing frames 400 to a suitable height. Tighten the nuts and fix the two fixing frames 400 to the bus duct body 100 in turn to complete the installation. The seismic-resistant bracket for the bus duct optimizes the structure of the traditional spring supporter and adds a column 330 at the bottom of the reset spring 320 for limiting the first bolt 310, which cooperates with the first support 340 and the second support 350 fixedly connected to the first channel steel 210 and the second channel steel 220 respectively, to provide additional support for the installation of the first bolt 310, effectively reduce the probability of its bending deformation, and extend the service life of the first bolt 310.

[0029] Furthermore, both sides of the top of the first channel steel 210 and the top of the second channel steel 220 are provided with strip holes 240 respectively distributed along the length direction of the two, and the strip holes 240 are adapted to the second bolts 360. The provision of the strip holes 240 makes the installation positions of the two second bolts 360 respectively corresponding to the first support 340 and the second support 350 adjustable, thereby improving the flexibility of installation. At the same time, the strip holes 240 on the first channel steel 210 and the second channel steel 220 are respectively distributed along the length direction of the two, that is, the strip holes 240 on the first channel steel 210 can limit the second bolts 360 on the second support 350, and the strip holes 240 on the second channel steel 220 can limit the second bolts 360 on the first support 340, thereby not affecting the secure and stable installation of the column 330.

[0030] Furthermore, a limiting groove 370 is provided at the top of the column 330 for accommodating the bottom end of the return spring 320, and the limiting groove 370 is coaxially distributed with the column 330. The limiting groove 370 provides a limit for the bottom of the return spring 320, further improving the stability of the return spring 320.

[0031] Furthermore, two L-shaped clamping plates 430 are assembled on the inner side of the fixing frame 400 through the third bolt 420. The two clamping plates 430 are symmetrically distributed and are respectively arranged on the front and rear sides of the inner side of the fixing frame 400. The inner side of the fixing frame 400 is provided with an installation groove 440 for accommodating the head of the third bolt 420 and distributed along the length direction of the fixing frame 400. Among them, the fixing frame 400 serves as a connecting piece between the elastic connector 300 and the bus duct body 100, and a variety of connection methods can be used to achieve assembly with the bus duct body 100. For example, the two fixing frames 400 can be fixedly connected by two tension bolts, and the two fixing frames 400 can be directly fixedly connected to the bus duct body 100 by a number of screws respectively. Preferably, two clamping plates 430 are arranged on the inner side of the fixing frame 400 to achieve clamping and fixing connection with the bus duct body 100. By means of the inner side surfaces of the two clamping plates 430 respectively fitting with the front and rear side surfaces of the bus duct body 100, the level of the installation of the fixing frame 400 can be ensured.
