Description

Technical Field

[0001] The utility model is a cable bridge side longitudinal earthquake-resistant support and hanger, belonging to the cable earthquake-resistant technical field. Background Art

[0002] When an earthquake occurs, the cable rack needs to be able to withstand the shock and vibration caused by the earthquake to ensure the safety and stability of the cables. Earthquake-resistant cable racks are usually made of high-strength materials such as steel or aluminum alloy. They are designed to effectively disperse the seismic force and transfer it to the ground or building structure to avoid damage or displacement of the cables due to the earthquake.

[0003] Chinese patent number CN214153872U discloses an anti-seismic support and hanger for a cable tray. The device is composed of a support plate, a vertical rod, a fixed arm, a horizontal rod, a first connecting arm, etc. The design pushes the sleeve of the slider to move through the third spring, so that a group of sleeves on the top of the support plate move toward each other to clamp the cable. However, when the cable shakes, the third spring will be pushed to move left and right, so that the cable will be out of its original position. Therefore, there is an urgent need for a side longitudinal anti-seismic support and hanger for the cable tray to solve the above-mentioned problems. Utility Model Content

A connecting shaft 2 is provided on the left and right sides of the screw 1, and a connecting shaft 1 is provided on the left and right sides of the screw 2, and bearings are sleeved on the outside of the connecting shaft 1 and the connecting shaft 2. Limit blocks are provided on both sides of the moving block 1 and the moving block 2, and the limit blocks are placed inside the limit grooves. The limit grooves are opened on the front and back sides of the top of the support frame.

[0006] Furthermore, the threads on the outside of the first screw are forward threads, and the threads on the outside of the second screw are reverse threads.

[0007] Furthermore, a placement groove 1 is provided on the top of the support frame, and the interior of the placement groove 1 matches the exterior of the moving block 1 and the moving block 2.

[0008] Furthermore, a second placement groove is provided at the middle position of the top of the support frame, and the interior of the second placement groove is connected to a second connecting shaft provided at the left end of the first screw and a first connecting shaft provided at the right end of the second screw.

[0011] The beneficial effects of the utility model are as follows: the cross hole opened by the connecting shaft 2 at the right end of the screw 1 is plugged into the corresponding operating rod, and the operating rod is rotated to one side, so the rotation of the screw 1 will cause the screw 2 to rotate as well. Since the thread outside the screw 1 is a positive thread and the thread outside the screw 2 is a reverse thread, the moving block 2 outside the screw 2 and the moving block 1 outside the screw 1 can move toward each other, so that a group of cable clamping assemblies on the top of the support plate can clamp the cable. This design drives the screw 2 to rotate by the screw 1 so that the cable clamping assemblies move toward each other to clamp the cable, so the back and forth shaking of the cable will not cause the cable to fall off.

[0021] As the first embodiment of the utility model: the thread on the outside of the screw rod 102 is a forward thread, the thread on the outside of the screw rod 2 105 is a reverse thread, a placement groove 1 is provided on the top of the support frame 1, and the inside of the placement groove 1 matches the outside of the moving block 101 and the moving block 2 106. This design facilitates a group of cable clamping components 10 on the top of the support frame 1 to move toward each other, a placement groove 2 is provided in the middle position of the top of the support frame 1, and the inside of the placement groove 2 is connected to the connecting shaft 2 109 provided at the left end of the screw rod 102 and the connecting shaft 1 108 provided at the right end of the screw rod 2 105. This design facilitates the docking of screw rod 102 and screw rod 2 105.

[0022] As the second embodiment of the present utility model: first, the left and right sides of the top of the support plate 5 are connected with the anchor rods inserted into the bottom of the concrete support beam, and then the tops of the longitudinal force-bearing rods 3 and the transverse force-bearing rods 4 are fixed to the bottom of the concrete support beam through the anchor rods, so that the support frame 1 is installed with the bottom of the concrete support beam, so that the cable can be arranged and the cable passes through the bottom of the support plate 5. At this time, the cable will be placed in the middle position of a group of cable clamping assemblies 10 provided on the top of the support frame 1, so that the cross hole provided on the connecting shaft 2 109 at the right end of the screw rod 102 is plugged into the corresponding operating rod, and by rotating the operating rod to one side, the screw rod 102 at this time is connected to the card block provided on the connecting shaft 2 109 at the left end and the card groove provided on the connecting shaft 108 at the right end of the screw rod 2 105, and then through the connecting shaft 108 and the bearing 107 provided on the connecting shaft 2 109, the screw rod 102 The rotation will cause the screw rod 2 105 to rotate as well.

Therefore, the stability of the moving block 101 and the moving block 2 106 can be increased. When the left and right sides of the support frame 1 vibrate, the lateral force-bearing rod 4 will be subjected to force to prevent the support frame 1 from vibrating left and right. When the front and rear sides of the support frame 1 vibrate, the longitudinal force-bearing rod 3 will be subjected to force to prevent the support frame 1 from vibrating back and forth. This design drives the screw rod 2 105 to rotate by the screw rod 102 to move the cable clamping assembly 10 toward each other to clamp the cable, so the back and forth shaking of the cable will not cause the cable to detach.
