Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a high-stability trough-type large-span cable bridge. Background Art

[0002] A cable tray is a device used to carry and lay cables. It can arrange and fix the cables neatly and orderly and protect the cables. The trough-type large-span cable tray is a cable tray with good sealing, strong carrying capacity, high stability and easy installation. It is often used in large industrial plants, subways, tunnels and other scenes.

[0003] According to the utility model with authorization announcement number CN210246211U, a high-stability trough-type large-span cable bridge is disclosed. Although the cable bridge can strengthen the structural strength of the trough-type cable support plate and the trough cover plate and improve the load-bearing stability by arranging strip-shaped reinforcing protrusions on the trough-type cable support plate and the trough cover plate, and by opening heat dissipation holes at the bottom of the trough-type cable support plate, ventilation and heat dissipation of the internal cables can be carried out to provide safety and stability, and adjacent trough-type cable support plates can be connected through a detachable connector to improve the stability of the installation of the trough-type cable support plate, but the cables are simply placed between the support plate and the cover plate, which is easy to cause relative shaking and collision between the internal cables of the bridge and the bridge due to the external force exerted on the external cables of the bridge. There is a lack of a limiting buffer structure to increase the relative stability between the cables and the bridge, which makes it easy for the external cables of the bridge to cause relative shaking and collision between the internal cables of the bridge and the bridge after being subjected to external force, thereby making the stability of the bridge relatively general; to this end, we provide a high-stability trough-type large-span cable bridge to solve the above problems.

[0023] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5A high-stability trough-type large-span cable tray comprises a hollow trough support plate 1, a limited buffer mechanism 2 is arranged above the hollow trough support plate 1, the limited buffer mechanism 2 comprises a trough cover plate 201, the inner wall of the trough cover plate 201 and the inner wall of the hollow trough support plate 1 are threadedly connected with two groups of fastening bolts 202, the inner wall of the trough cover plate 201 is in contact with the outer surface of the hollow trough support plate 1, and the outer surface of each group of fastening bolts 202 is sleeved with two washers 3, and the side of each washer 3 close to the trough cover plate 201 is in contact with the outer surface of the trough cover plate 201, and the hollow trough support plate 1 has a plurality of heat dissipation ports, and thus has good heat dissipation. By providing a washer 3, it can be padded between the trough cover plate 201 and the fastening bolt 202, thereby increasing the contact area between the two, thereby increasing the fastening effect of the fastening bolt 202.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A support plate 203 is provided inside the slot cover plate 201, and two moving blocks 204 are slidably connected inside the slot cover plate 201. The bottom surface of each moving block 204 is fixedly connected to the upper surface of the support plate 203. Two buffer pads 4 are fixedly connected to the upper surface of the hollow slot support plate 1, and the upper surface of each buffer pad 4 is in contact with the inner top wall of the slot cover plate 201. By providing the buffer pads 4, a buffer can be formed between the slot cover plate 201 and the hollow slot support plate 1 when they are spliced, which increases the safety and stability of the splicing of the two.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A hollow pressing plate 205 is arranged inside the hollow slot support plate 1. The two side surfaces of each moving block 204 are fixedly connected to the limiting sliders 5. The outer surface of each limiting slider 5 is slidably connected to the inside of the slot cover plate 201. The hollow pressing plate 205 has multiple heat dissipation ports, so it has better heat dissipation when pressing the cable. By providing the limiting slider 5, it can slide up and down inside the slot cover plate 201, so as to increase the stability of the moving block 204 sliding up and down inside the slot cover plate 201.

[0026] Reference Figure 1 , Figure 2 and Figure 3The inner wall of the slot cover 201 is threadedly connected with two hand-tightened tightening bolts 206, and one end of each hand-tightened tightening bolt 206 close to the moving block 204 is in contact with the outer surface of the moving block 204. A limiting connecting plate 8 is arranged above the slot cover 201, and the upper surface of each moving block 204 is fixedly connected to the bottom surface of the limiting connecting plate 8. By setting the limiting connecting plate 8, the two moving blocks 204 can be connected and the moving blocks 204 can be prevented from completely sliding away from the inside of the slot cover 201, so that when the limiting connecting plate 8 is held by hand, the positions of the two moving blocks 204 and the support plate 203 relative to the slot cover 201 can be adjusted together, which facilitates the adjustment of the number and size of cables that can be limited by the hollow pressure plate 205.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The upper surface of the hollow pressure plate 205 and the bottom surface of the support plate 203 are fixedly connected with two groups of dampers 207. The outer surface of the limiting connecting plate 8 is fixedly connected with an anti-slip sleeve 9. The outer surface of the anti-slip sleeve 9 is fixedly connected with a number of identical anti-slip convex discs 10. By providing the anti-slip convex discs 10, the anti-slip effect and hand-holding comfort of the outer surface of the anti-slip sleeve 9 can be increased. By providing the anti-slip sleeve 9 and the anti-slip convex discs 10, the anti-slip effect and hand-holding comfort of the outer surface of the limiting connecting plate 8 can be increased together.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The outer surface of each group of dampers 207 is sleeved with two return springs 208, and the two ends of each return spring 208 are respectively in contact with the upper surface of the hollow pressure plate 205 and the bottom surface of the support plate 203, and the inner bottom wall of the hollow trough support plate 1 is fixedly connected with a first hollow anti-skid pad 6, and the bottom surface of the hollow pressure plate 205 is fixedly connected with a second hollow anti-skid pad 7. By providing the first hollow anti-skid pad 6, the anti-skid effect of the inner bottom wall of the hollow trough support plate 1 relative to the cable can be increased. By providing the second hollow anti-skid pad 7, the anti-skid effect of the hollow pressure plate 205 relative to the cable can be increased, thereby increasing the relative stability of the cables inside the entire bridge.

[0029] Working principle: When in use, first suspend and fix the hollow slot support plate 1 through the external support frame, then put the cable into the hollow slot support plate 1, and then cover the slot cover plate 201 on the hollow slot support plate 1, and then use the fastening bolts 202 and the washers 3 to fasten the slot cover plate 201 and the hollow slot support plate 1. During this period, since the hollow pressure plate 205 cooperates with the hollow slot support plate 1 to clamp cables of different numbers and sizes, the moving block 204 will slide upward in the slot cover plate 201, and then hold the anti-slip sleeve 9 and the anti-slip convex disc 10 on the outer surface of the limiting connecting plate 8 and press the support plate 203 down to a certain extent. At this time, the cable in the hollow slot support plate 1 is pressed by the hollow slot support plate 1 and the hollow pressure plate 205, and then the tightening screw is tightened by hand. Bolt 206 and make it press against the outer surface of the moving block 204, thereby fixing the position of the support plate 203 relative to the slot cover plate 201. When the cables outside the bridge are shaken relative to the bridge by external force, the damper 207 and the return spring 208 will form a good seismic buffer effect between the hollow pressure plate 205 and the support plate 203, which greatly increases the stability between the cable and the bridge. The design of the entire high-stability trough-type large-span cable bridge effectively solves the problem of lack of a limiting buffer structure to increase the relative stability between the cable and the bridge, which makes the external cables of the bridge easy to shake and collide with the internal cables of the bridge after being subjected to external force, thereby making the stability of the bridge relatively general.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
