Description

Technical Field

[0001] This utility model relates to the field of tunnel cable laying technology, specifically a transverse cable laying device suitable for tunnels with low headroom. Background Technology

[0002] In subway construction, cable supports are a crucial component of underground tunnels, running the entire length of the tunnel to support and secure cables. During cable installation, workers must lay the cables on top of the supports. However, existing cable laying methods rely on cable laying frames, which are moved to lay the cables.

[0003] Traditional cable laying methods typically use railcars for cable transportation. The railcar's flatbed is quite high above the rail surface (usually 1 meter), which limits the length of each cable reel and cannot meet the needs of long-distance laying. In addition, due to the height of the railcar, the laid cables usually fall directly onto the track bed and need to be manually moved to the support structure. This not only increases the complexity of the work but also significantly increases the labor intensity. Therefore, a transverse cable laying device suitable for low-headroom tunnels is proposed.

[0011] As a further embodiment of this utility model: the two first lifting rods are connected by a limiting beam, and the limiting beam is adjacent to the bearing plate.

[0012] As a further embodiment of this utility model: the lifting structure includes at least one set of hydraulic cylinders, one end of the hydraulic cylinder is connected to the moving crossbeam, the other end of the hydraulic cylinder is equipped with a connecting piece, the hydraulic cylinder is connected to the fixed crossbeam through the connecting piece, and the two ends of the fixed crossbeam are respectively connected to two first lifting rods.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 In this embodiment of the present invention, a transverse cable laying device suitable for low-headroom tunnels includes a support vehicle 1 for placing the cable winding reel 2. The support vehicle 1 includes a base plate structure 11 and a load-bearing structure 13. The base plate structure 11 and the load-bearing structure 13 are connected by a lifting structure 12 for controlling the load-bearing structure 13 to adjust to different heights. By combining the lifting structure 12 and the load-bearing structure 13, the adjustment of the base plate structure 11 to different heights can be met, thereby reducing the number of times cables need to be manually moved.

[0023] Please see Figure 3In one embodiment, preferably, the base plate structure 11 includes a square frame 111 and multiple sets of wheels 112 disposed below the square frame 111. There are four sets of wheels 112, each located at one of the four corners of the square frame 111. The type of wheels 112 is not limited; they can be omnidirectional wheels, track wheels, or other types of wheels. The selection of wheels 112 can be based on the actual site conditions. Symmetrical first grooves 113 are provided on the inner side of the square frame 111, and each of the two first grooves 113 contains a... There is a first rotating wheel 115 that can slide along its interior. The two first rotating wheels 115 are connected by a movable crossbeam 114. The presence of the first sliding groove 113 can restrict the movement direction of the first rotating wheel 115. As the first rotating wheel 115 moves, the included angle between the first lifting rod 131 and the second lifting rod 132 changes. When the included angle between the first lifting rod 131 and the second lifting rod 132 is larger, the height of the bearing structure 13 will be lower. When the height of the bearing structure 13 is reduced to the minimum, the handling of the cable will be much easier.

[0024] Please see Figure 3 In one embodiment, preferably, a handrail 116 is installed on the square frame 111. The presence of the handrail 116 provides a stable handhold area for the staff, which makes it easier to move the wire feeding device.

[0025] Please see Figure 3 In one embodiment, preferably, the supporting structure 13 includes a supporting plate 135 for placing the cable winding reel 2. Symmetrically arranged second sliding grooves 136 are provided on the inner side of the supporting plate 135. Each of the two second sliding grooves 136 is equipped with a second rotating wheel 134 that can slide along its interior. The presence of the second sliding grooves 136 and the second rotating wheels 134 ensures that the supporting plate 135 can be smoothly adjusted in height. The two second rotating wheels 134 are connected to the moving crossbeam 114 via two first lifting rods 131. The square frame 111 and the supporting plate 135 are connected via two second lifting rods 132. The first lifting rods 131 and 132 located on the same side are connected via a rotating shaft. Both the first lifting rods 131 and 132 are two-section structures, and the two sections are rotatably connected by a rotating shaft. The two first lifting rods 131 are connected via a limiting crossbeam 133, and the limiting crossbeam 133 is adjacent to the supporting plate 135.

[0026] Please see Figure 3In one embodiment, preferably, the lifting structure 12 includes at least one set of hydraulic cylinders 121. In this embodiment, preferably, there are two sets of hydraulic cylinders 121. The two sets of hydraulic cylinders 121 can better ensure the balance of the bearing plate 135. One end of the hydraulic cylinder 121 is connected to the moving crossbeam 114, and the other end of the hydraulic cylinder 121 is equipped with a connector 122. The hydraulic cylinder 121 is connected to the fixed crossbeam 123 through the connector 122. The two ends of the fixed crossbeam 123 are respectively connected to two first lifting rods 131.

[0027] Please see Figure 3 In one embodiment, preferably, the cable winding reel 2 includes a reel surface 21 and a connecting shaft 23. The reel surface 21 has two sets and is fixed to the outer wall of the connecting shaft 23. The surface of the upper reel surface 21 has several sets of slots 22. The bottom end of the connecting shaft 23 is rotatably connected to the top end of the bearing plate 135, realizing the rotatable connection between the cable winding reel 2 and the support carriage 1. The two sets of reel surfaces 21 are fixedly sleeved on the outer circumferential surface of the connecting shaft 23, forming a space for cable winding between the two sets of reel surfaces 21. In addition, the design of the slots 22 matches the cable, which facilitates the cable to be inserted into the slots 22. At the same time, the cable winding reel 2 is placed horizontally, which can effectively increase the length of the reel and the maximum length of each cable reel, effectively improving the cable laying efficiency. In addition, the combination of the cable winding reel 2 and the support carriage 1 is detachable, and can be disassembled and reused after the cable is laid.

[0028] The working principle and usage process of this utility model: Workers can push the equipment forward using the handle 116, and the wheels 112 can change the travel route; when the supporting structure 13 needs to be lifted, the hydraulic cylinder 121 extends outward, pushing the moving crossbeam 114 forward, then pushing the fixed crossbeam 123 and the first lifting rod 131 backward. At this time, the second rotating wheel 134 slides backward in the second slide groove 136, and the second lifting rod 132 rotates synchronously with the movement of the first lifting rod 131; during normal operation... When the cable winding reel 2 is in operation, the hydraulic cylinder 121 is in a retracted state, and the first lifting rod 131 is also folded and stored. The bearing structure 13 is attached to the top of the base plate structure 11, which makes it convenient for workers to wind the cable around the surface of the cable winding reel 2. The bottom end of the connecting shaft 23 is rotatably connected to the top end of the bearing plate 135, realizing the rotatable connection between the cable winding reel 2 and the support vehicle 1. When winding the cable, one end of the cable can be inserted into the slot 22 to fix the cable. Then, rotating the cable winding reel 2 can complete the winding and fixing of the cable.
