Description

Technical Field

[0001] This utility model relates to the field of pre-embedded channel technology, specifically a pre-embedded channel positioning device for subway tunnel segments. Background Technology

[0002] Subway tunnel segments are the core load-bearing structure of subway shield tunnels, serving functions such as supporting ground pressure and preventing seepage. The pre-embedded channels installed on their surfaces are load-bearing anchoring components pre-embedded within the tunnel segments, mainly used for later equipment installation.

[0003] Currently, some pre-embedded channels are quite large and need to be fitted to subway tunnel segments during installation. Some pre-embedded channels installed at an angle require multiple workers to support them before installation to ensure their stability. Only then can another worker use tools to fix the position of the pre-embedded channel. This process requires a lot of manpower. In addition, workers' arms are prone to fatigue when supporting pre-embedded channels at an angle, and dust generated during the installation process can easily fall into the faces and eyes of workers below, thus affecting their health.

[0004] The purpose of this invention is to provide a pre-embedded channel positioning device for subway tunnel segments to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for pre-embedded channels in subway tunnel segments, comprising: A storage unit, comprising a storage component and a foot pedal disposed below the surface of the storage component, wherein a recessed groove is provided on the top of the foot pedal; A limiting assembly is installed inside the storage component, and the limiting assembly includes a longitudinally movable optical rod. A support assembly is installed on top of the limiting assembly. The support assembly includes a base welded to the top of the guide rod, a bracket rotatably connected inside the base, and clamping plates set at both ends of the bracket.

[0006] Preferably, a disc is welded to the bottom of the optical rod and slidably connected to the inner wall of the storage component, and the surface of the disc is provided with a groove.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-6 As shown, the positioning device for the pre-embedded channel of subway tunnel segments includes a storage group 100. The storage group 100 includes a storage component 110 and a foot pedal 120 disposed below the surface of the storage component 110. The top of the foot pedal 120 is provided with a recessed groove, which is convenient for workers to step on, so that workers can use their own weight to restrict the position of the device. The storage component 110 is provided with a movable limiting group 200 inside. The top of the limiting group 200 is equipped with a rotatable support group 300. The limiting group 200 includes a longitudinally lifting rod 210. The bottom of the rod 210 is welded with a disc 220 that slides and connects with the inner wall of the storage component 110. The disc 220 is disposed on the top of the rod 210, which not only guides the movement of the rod 210, but also limits the movement distance of the rod 210.

[0017] The support assembly 300 includes a base 310 welded to the top of the smooth rod 210. A bracket 320 is rotatably connected inside the base 310. The surface of the bracket 320 has a protruding structure that rotatably penetrates the base 310. Both ends of the bracket 320 are equipped with clamping plates 330, which are U-shaped and can push the pre-embedded channel onto the subway tunnel segment to restrict its position. The surface of the base 310 has a filling part 340, which includes a filling element 341 that slides through the base 310 and the bracket 320. One end of the filling element 341 is fixedly connected to a vertical plate 342. A guide rod 343 is fixedly connected to the lower surface of the vertical plate 342 and slides through it. The base 310 can guide the movement of the vertical plate 342. One end of the guide rod 343 is fixedly connected to the partition 344. The surface of the guide rod 343 is fitted with a spring 345. When the tension on the vertical plate 342 is released, under the action of the spring 345, the vertical plate 342 can drive the filler 341 to move and pass through the bracket 320, thereby fixing the angle of the bracket 320. The clamping plate 330 can stably support the pre-embedded channel. The base 310 and the partition 344 are fixedly connected to the bellows cover 346. The bellows cover 346 covers the surface of the guide rod 343 and the spring 345, and plays a role in protecting the spring 345. The limiting group 200 also includes a positioning part 240 that can move laterally. The surface of the disc 220 has a groove 230 that mates with the positioning part 240. The positioning part 240 includes a reinforcement 241 welded to the surface of the storage member 110. A movable shaft 242 is movably connected through the surface of the storage member 110. The movable shaft 242 movably passes through the reinforcement 241, and a positioning member 243 is fixedly connected to one end of the movable shaft 242. The surface of the positioning member 243 contacts the inner wall of the reinforcement 241. An extension member 244 is rotatably connected to the other end of the reinforcement 241. When the positioning member 243 is placed inside the reinforcement 241, the movable shaft 242 pushes the extension member 244 to move to... Figure 2 In the indicated state, the corresponding extension 244 is inserted into the groove 230 to limit the height of the disc 220. The operator rotates the positioning part 243 by 90 degrees and then pulls the positioning part 243. The moving shaft 242 drives the extension 244 to move. After the contact between the extension 244 and the groove 230 is released, the height of the disc 220 and the light rod 210 can be adjusted. The upper and lower surfaces of the extension 244 are welded with horizontal shafts 245. The horizontal shafts 245 slide through the storage part 110. One end of the horizontal shafts 245 is welded with a shielding part 246. The shielding part 246 has an arc design. The inner surface of the shielding part 246 fits against the surface of the storage part 110. The horizontal shafts 245 can guide the movement of the extension 244. When the light rod 210 is raised, the height of the support group 300 at its top can be adjusted accordingly, so that the operator can flexibly adjust the support group 300 according to the usage status of the device.

[0018] Working principle: The operator rotates and pulls the positioning component 243, causing the moving shaft 242 to move the extension component 244. The contact between the extension component 244 and the groove 230 is released. The operator then lifts the support assembly 300 upwards, causing the smooth rod 210 to move the disc 220. When the support assembly 300 reaches the appropriate height, the operator pushes the positioning component 243 and rotates it 90 degrees in the opposite direction. The positioning component 243 engages with the reinforcement component 241, restricting the position of the extension component 244. The extension component 244 moves into the groove 230, supporting the disc 220. At this point, the weight of the disc 220... The position of the extension 244 can be reinforced in reverse. After the staff pulls the vertical plate 342 to release the contact between the filler 341 and the bracket 320, the angle of the bracket 320 can be adjusted according to the installation angle of the pre-embedded channel. The staff will press the bracket 320 tightly against the subway tunnel segment and move the device to one side of the pre-embedded channel. At this time, the clamping plate 330 will clamp the pre-embedded channel and restrict its movement, thereby reinforcing the position of the pre-embedded channel. During this process, the staff can stand on the foot pedal 120 to reinforce the position of the device and the pre-embedded channel. The pre-embedded channel is positioned, and the staff can install the pre-embedded channel.
