Description

Technical Field

[0001] This utility model relates to the field of tunnel maintenance technology, specifically to an auxiliary lifting device for maintaining cable trench covers in tunnels. Background Technology

[0002] Cable trench covers are protective covers installed on top of cable trenches. When maintaining cables within the trench, operators must lift the cover from the top and move it to the vicinity, a time-consuming and labor-intensive process. While existing technologies include devices to assist in lifting the covers, most employ a trolley with a top-mounted support shaft, using levers to assist lifting. These existing devices are only suitable for cable trenches on flat ground. However, cable trenches in highway tunnels often have a significant height difference from the road surface, making traditional trolley-type cover lifting devices unsuitable for tunnel cable trenches. Therefore, we propose an auxiliary lifting device for maintaining cable trench covers in tunnels. Utility Model Content

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example 1

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: an auxiliary lifting device for cable trench covers in tunnels, including a fixed frame 1. The bottom of the fixed frame 1 is symmetrically welded with a first support frame 2 and a second support frame 3. Movable components 4 are fixedly installed in the first support frame 2 and the second support frame 3 respectively. The fixed frame 1 is moved by the movable components 4. The height of the first support frame 2 is 80cm and the height of the second support frame 3 is 30cm. The different heights of the first support frame 2 and the second support frame 3 make the device adaptable to the cable trenches on both sides of the tunnel, which facilitates the auxiliary lifting of the covers on the top of the cable trenches.

[0021] like Figure 1 As shown, the moving component 4 includes a first moving wheel 41 and a second moving wheel 42. The first moving wheel 41 is mounted on the outer side wall of the first support frame 2 and the second support frame 3. The first moving wheel 41 is a large solid rubber wheel. The second moving wheel 42 is mounted on the bottom of the first support frame 2 and the second support frame 3. The second moving wheel 42 is a smaller auxiliary moving wheel. The first moving wheel 41 can improve the convenience of moving the fixed frame 1 during the movement of the fixed frame 1, making it easier for the staff to push the fixed frame 1. The second moving wheel 42 can adjust the movement direction of the fixed frame 1, making it easier for the fixed frame 1 to be pushed along the cable trench.

[0022] A support frame 5 is welded to the top of the fixed frame 1. A rotating frame 6 is mounted on the top of the support frame 5. An auxiliary handle 7 is welded to one end of the rotating frame 6, and a first auxiliary bracket 8 is welded to the other end of the rotating frame 6. By rotating the rotating frame 6 along the support frame 5, the first auxiliary bracket 8 lifts the cover plate on the top of the cable trench, making it easier for subsequent workers to separate the cover plate from the cable trench. An auxiliary handle 9 is welded to the top of the fixed frame 1. The auxiliary handle 9 is used in conjunction with the fixed frame 1, and the fixed frame 1 can be moved by pushing it.

[0023] like Figure 2 As shown, the rotating frame 6 is made of hollow iron pipe welded together. It includes a fixed pipe 61 and a T-shaped pipe 62. The T-shaped pipe 62 is welded and fixed to the end of the fixed pipe 61. The first auxiliary bracket 8 is welded and fixed to the bottom of the T-shaped pipe 62. A fixing block 63 is welded and fixed to the middle position of the fixed pipe 61. An arc-shaped groove 64 is provided at the bottom of the fixing block 63. The arc-shaped groove 64 is used to cooperate with the support frame 5. By setting the arc-shaped groove 64, the rotating frame 6 can rotate along the support frame 5.

[0024] like Figure 3 As shown, the fixed tube 61 and the T-shaped tube 62 are detachably fixedly connected by the fixing bolts 10 and the fixing nuts 11. When transporting this utility model, the rotating frame 6 can be disassembled, thereby reducing the space occupied by the overall device and making it easier to transport the device by truck.

[0025] like Figure 1 As shown, the auxiliary handle bracket 9 has a slot 91 inside, which is used to hold tools such as hammers. The side wall of the fixed bracket 1 is welded and fixed with hooks, which are used to hang other tools, improving the convenience of using the fixed bracket 1 and allowing the fixed bracket 1 to carry more different tools during use, which is convenient for workers to carry during construction.

[0026] Working principle: such as Figure 1 and Figure 4 As shown, this utility model is mainly used for opening the top cover of the cable trench during maintenance in the tunnel. First, the entire device is transported to the designated construction location in the tunnel by truck. Then, the fixing frame 1 is assembled on the top of the cable trench. Subsequently, the rotating frame 6 is assembled. Then, the arc groove 64 at the bottom of the rotating frame 6 is engaged with the top of the support frame 5. This utility model requires three operators to operate. Operator 1 pushes the fixing frame 1 along the top of the cable trench through the auxiliary handle 9. Operator 2 controls one end of the rotating frame 6 equipped with the auxiliary handle 7. By rotating the rotating frame 6, the first auxiliary bracket 8 can be inserted into the bottom position of the cover. As the rotating frame 6 rotates, the cover can be lifted by the first auxiliary bracket 8. Subsequently, operator 3 tilts the cover and places it on the top of the cable trench.

[0027] Example 2

[0028] Please see Figure 5 The technical solution provided in this embodiment differs from that in Embodiment 1 in that: the top of the support frame 5 is rotatably connected to a first assembly frame 12 and a second assembly frame 13. Both the first assembly frame 12 and the second assembly frame 13 are composed of an annular body and a fixed shaft. The annular body is rotatably connected to the outer wall of the support frame 5, and the fixed shaft is welded and fixed to the side wall of the annular body. The top of the first assembly frame 12 and the second assembly frame 13 are respectively equipped with a first rotating tube 14 and a second rotating tube 15. The first rotating tube 14 and the second rotating tube 15 are respectively sleeved on the outer wall of the fixed shaft. The end of the first rotating tube 14 is welded and fixed with a second auxiliary bracket 16, and the end of the second rotating tube 15 is welded and fixed with a lifting bracket 17. The lifting bracket 17 is located inside the second auxiliary bracket 16.

[0029] Working principle: The difference between this embodiment and the first embodiment is that a first rotating pipe 14 and a second rotating pipe 15 that can rotate along the support frame 5 are provided. The first rotating pipe 14 replaces the rotating frame 6. The first rotating pipe 14 rotates along the support frame 5 through the first assembly frame 12, which can cause the second auxiliary bracket 16 at the end to move, separating the cable trench cover from the cable trench. Then, the second rotating pipe 15 is controlled to drive the lifting bracket 17 to move, so that the lifting bracket 17 rises from the second auxiliary bracket 16, making it easier to separate the cable trench cover from the second auxiliary bracket 16, thus making it more convenient for the operator to lift the three pairs of covers.
