Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to an anti-seismic bracket of a cable bridge. Background Art

[0002] At present, a Chinese utility model with the announcement number CN212277816U discloses an anti-seismic bracket for a cable bridge, including two fixed plate bodies, the bottoms of the two fixed plate bodies are fixedly installed with limit seats, the interiors of the two limit seats are provided with buffer cavities, and the inner walls of the left and right sides of the buffer cavities are fixedly installed with extension blocks. The anti-seismic bracket of the cable bridge is installed with an extrusion block on the limit groove, and a buffer spring fixedly connected to the inner bottom wall of the buffer cavity is installed on the buffer block. When vibration occurs, the bridge body will shake, thereby generating a pulling force on the connecting rod, and the connecting rod will pull the buffer block to move downward. When the buffer block moves downward, it will be squeezed with the extrusion sheet and the extrusion block, and the buffer spring will push the buffer block upward. In this process, most of the inertia will be offset, which can prevent the fixed plate body from falling off, thereby achieving the purpose of good anti-seismic effect.

[0003] Although the existing brackets are equipped with anti-seismic effects and can offset the inertia when the bridge frame vibrates, there are still other problems during use. For example, they do not have a height adjustment function, and the height of the bracket is fixed. Since more brackets are required for laying a longer bridge frame, when the wall tops installed on the tops of the same specifications are at different heights, the bottom of the bracket will be inconsistent after installation, and personnel need to cut on the spot. The applicability is low, and it is not convenient for quick disassembly and assembly of the bridge frame. When the bracket is connected to the bridge frame after fixing, holes are drilled on both sides and tightened with screws. Tools are needed to assist in screwing and removing, which is cumbersome and complicated, reducing the installation efficiency of personnel. In order to solve the above-mentioned problems, we propose an anti-seismic bracket for a cable bridge. Utility Model Content

[0004] The utility model aims to provide an anti-seismic bracket for a cable bridge, which solves the problem that the existing anti-seismic bracket has no height adjustment function and is not convenient for quick disassembly and assembly of the bridge.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: an earthquake-resistant bracket of a cable tray, comprising a U-shaped plate, two adjusting plates are placed on the top of the U-shaped plate, threaded rods are welded on both sides and the inside of the U-shaped plate, sliding grooves are opened on both sides of the adjusting plate, the other end of the threaded rod passes through and extends to the outside of the sliding groove, the surface of the threaded rod is threadedly connected with a fixing nut, an earthquake-resistant mechanism is arranged on the top of the adjusting plate, a placing plate is installed inside the U-shaped plate, a bidirectional screw is rotatably connected inside the U-shaped plate, the surface of the bidirectional screw is threadedly connected with two threaded plates, and a clamping plate is welded on the top of the threaded plate.

[0006] The above technical solution can have a height adjustment function, and the distance between the bridge frame and the wall top after installation can be adjusted, thereby improving the applicable environment of the bracket and having good flexibility. At the same time, it can facilitate the quick disassembly and assembly of the bridge frame, and the operation is simple and labor-saving, which speeds up the installation efficiency of personnel and is highly practical.

[0007] The utility model is further configured as follows: the anti-seismic mechanism includes a fixed frame, the number of the fixed frames is two, the two fixed frames are respectively arranged on the top of the two adjusting plates, a mounting plate welded to the adjusting plate is arranged inside the fixed frame, a fixing spring is bolted between the bottom of the mounting plate and the fixed frame through a spring fixing sheet, and a damper is installed between the bottom of the mounting plate and the fixed frame.

[0008] By adopting the above technical solution, through the setting of the fixed frame, the mounting plate, the fixed spring and the damper, it can have an anti-seismic function, and can offset the inertia generated by the vibration of the bridge frame, thereby preventing the inertia from being transmitted to the top of the wall and causing the bolts to loosen.

[0009] The utility model is further configured as follows: a mounting hole is provided on the top of the fixing frame.

[0010] By adopting the above technical solution and setting the mounting holes, it is convenient for personnel to fix the fixing frame on the top of the wall with screws.

[0011] The utility model is further configured as follows: a slide rail is bolted inside the U-shaped plate, and a sliding block slidably connected to the slide rail is welded at the bottom of the threaded plate.

[0012] By adopting the above technical solution, the threaded plate can be limited by setting the slide rail and the slider to prevent the threaded plate from rotating during the left and right movement.

[0013] The utility model is further configured as follows: rubber pads are installed on opposite sides of the two clamping plates.

[0014] By adopting the above technical solution, the bridge frame can be protected by providing the rubber pad, so as to prevent the clamping plate from scratching the surface of the bridge frame when clamping.

[0015] The utility model is further configured as follows: a turning handle is welded on the other end of the bidirectional screw.

[0016] By adopting the above technical solution and setting the turning handle, it is convenient for personnel to rotate the bidirectional screw.

[0017] The utility model is further configured as follows: the threaded rod and the fixing nut are both made of stainless steel.

[0018] By adopting the above technical solution, the threaded rod and the fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model first fixes the fixing frame to the specified position with screws, and then uses tools to loosen the fixing nuts after the fixing frame is fixed. After the fixing nuts are loosened, the pressure on the threaded rod and the U-shaped plate will be released, and then the U-shaped plate can be grasped to adjust the distance up and down. After the U-shaped plate is adjusted, the fixing nuts can be tightened again. The utility model has a height adjustment function, and the distance between the bridge frame and the wall top after installation can be adjusted, thereby improving the applicable environment of the bracket and having good flexibility.

[0021] 2. The utility model places the bridge between the two clamping plates on the placement plate. After the bridge is placed, the user holds the handle by hand to drive the bidirectional screw to rotate. When the bidirectional screw rotates, it drives the two threaded plates to move inward synchronously through the cooperation of the slide rail and the slider. When the threaded plate moves inward, it drives the clamping plates to clamp the bridge, which can facilitate the quick disassembly and assembly of the bridge. The operation is simple and labor-saving, which speeds up the installation efficiency of the personnel and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
