Description

Technical Field

[0001] The utility model relates to the technical field of wiring auxiliary devices, in particular to an auxiliary device for cable laying. Background Art

[0002] Cable laying refers to the wiring and laying of various cables such as communication lines and cables in buildings or other places. When wiring inside a building, the wiring location is generally the top of the building, and a bridge is usually required for assistance; during the construction process, the bridge needs to be fixed on the top of the building with the opening of the bridge facing upward, and then a section of the cable is connected to the traction device, and then this section of the cable is placed inside the bridge. The bridge holds the cable, and then the cable is dragged inside the bridge through the traction device until the cable is laid. Cable laying is a meticulous and important task that affects the electricity consumption and network communication functions in the entire building. Therefore, when laying cables, careful planning, attention to safety and aesthetics, and reasonable wiring and fixing are required to provide stable and reliable power and network communication services.

[0003] When the bridge is fixedly installed, it is necessary to install the bridge section by section, and then splice the sections to form a sufficiently long bridge. When the bridge is fixedly installed, due to changes in the building structure, the bridge will undergo changes in height and structural changes in turns, which results in the spliced ​​bridge often being uneven at the connection position. When the cable passes through these uneven positions, the outer surface of the cable is easily worn or scratched by the bridge joint, causing damage to the cable.

[0004] The current solution is to set a cable laying auxiliary device inside the bridge, lift the cable through the cable laying auxiliary device, and place the cable on the roller of the auxiliary device. When the cable moves, the roller of the auxiliary device rotates synchronously to avoid contact between the cable and the bottom connection or inner wall of the bridge, thereby reducing damage to the protective skin of the cable. Moving the cable by the roller can also reduce the force of dragging the cable. However, the problem with the existing cable laying auxiliary device is that the existing auxiliary device basically has only one roller, which is rotatably mounted on a fixed bracket through a central axis. When the cable is pulled to move on the roller, the cable often swings left and right on the roller. When the cable swings to the gap between the roller and the bracket, it is easy to get stuck. Under the action of the dragging force, the protective skin of the cable is easily damaged, affecting the service life of the cable and the risk of leakage. In severe cases, the cable cannot be dragged because it is stuck.

[0005] Therefore, how to design a new structure of a cable laying auxiliary device so that when the cable passing through the auxiliary device is dragged forward, even if it swings at various angles, it will not be stuck between the roller and the bracket, thereby preventing the cable protective surface from being damaged, is a technical problem that has not yet been solved in the prior art. Utility Model Content

When it is necessary to place the cable above the second roller 92, the first plug-in portion 83 is pulled out from the insertion hole 93, and after the cable is placed in place, the first plug-in portion 83 is inserted and installed into the insertion hole 93; the second roller 92 is rotatably mounted on the second main body portion 96.

[0094] Circular threaded holes 94 are provided at both ends of the second roller 91, and the limiting bolts 10 are threadedly installed into the circular threaded holes 94. By adjusting the depth of the limiting bolts 10 installed into the circular threaded holes 94, the ends of the limiting bolts 10 can be adjusted to abut against the inner walls of both sides of the bridge frame, thereby enhancing the stability of the fixation.

[0095] Specifically, Fig.15 As shown, the limiting member 7 includes: a limiting body part 72, a first limiting threaded hole 74, a first limiting bolt 75, a limiting side plate 76, a second limiting threaded hole 77 and a second limiting bolt 78; wherein the limiting body part 72 is provided with a limiting mounting hole 73 for the top fixing plate 6 to be inserted; the first limiting threaded hole 74 is provided at the top of the limiting body part 72 and is connected to the limiting mounting hole 73; the first limiting bolt 75 is threadedly installed inside the first limiting threaded hole 74 for squeezing and fixing the top fixing plate 6; there are two limiting side plates 76, which are integrally formed below the limiting body part 72 , and form the second limiting groove 71; the second limiting threaded hole 77 is relatively opened on the limiting side plate 76; the second limiting bolt 78 is threadedly installed inside the second limiting threaded hole 77; before using the auxiliary device for cable laying of this embodiment, first put the limiting member 7 on the top fixing plate 6 through the limiting installation hole 73, and then squeeze and fix the limiting member 7 and the top fixing plate 6 through the first limiting bolt 75; when in use, adjust the position of the limiting member 7 according to the width of the bridge, so that the outer wall of the other side of the bridge can be snapped into the second limiting groove 71, and then squeeze and fix the outer wall of the bridge through the second limiting bolt 77.

[0096] Before use, snap one side outer wall of the bridge into the first limit groove 62, then adjust the position of the limiter 7 according to the width of the bridge, and snap the other side outer wall of the bridge into the second limit groove 71. When in use, first pass the traction rope through the closed space formed by the top fixing plate 6, the first roller assembly 8 and the second roller assembly 9, and then connect it with the cable; under the traction of the traction device, the traction rope drags the cable into the laying channel; when the cable swings left and right, the gap between the first roller assembly 8 and the second roller assembly 9 is very small, and the cable cannot enter the gap, so it will not enter the gap and be scratched or stuck.
