Description

Technical Field

[0001] This utility model relates to the field of seepage detection technology, specifically a seepage detection device for tunnel lining segments during shield tunnel construction. Background Technology

[0002] Publication No.: CN219142138U, Title: A Tunnel Segment Leakage Detection Device, which discloses: including a base and a rotating assembly, the upper end of the base is provided with a support frame, the rotating assembly is disposed inside the support frame, and the rotating assembly includes a motor, a connecting rod, a circular support plate, a short rotating block, a long rotating block, and a cylinder. The upper end of the motor is provided with a connecting rod, and the upper end of the connecting rod is provided with a circular support plate. Compared with existing tunnel segment leakage detection devices, this tunnel segment leakage detection device can adjust the nozzle to spray in all directions through the operation of the motor and the cylinder, and can also adjust the vertical distance of the nozzle to spray red liquid all over the segments in the tunnel, so that the red liquid spraying range is larger and the spraying effect is better. By moving the slider, the thin rod extends from the thick rod, so that the red liquid can be sprayed to the segments in the high position in the tunnel, increasing the detection distance of the device, thereby improving the practicality of the device.

[0003] The aforementioned disclosure describes how a slider moves to extend a thin rod from a thick rod, allowing the red liquid to be sprayed onto the tunnel segments at higher positions, thus increasing the equipment's detection distance. However, simply using a single nozzle to spray the tunnel wall, while enabling the nozzle to move closer to the tunnel wall, can only spray a small area at a time. This necessitates repeated operations to complete spraying a full circle of the tunnel wall. Utility Model Content

This device solves the problem that simply using a single nozzle to spray the tunnel wall, while allowing the nozzle to move closer to the tunnel wall, can only spray a small area at a time, requiring repeated operations to complete the spraying of the entire tunnel wall.

[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 1-5 This utility model provides a technical solution: a shield tunnel segment seepage detection device, including a mobile trolley 1, with lateral detection devices 2 on both sides of the mobile trolley 1 and a top detection device 3 on the top of the mobile trolley 1. The lateral detection device 2 includes two intersecting and slidably inserted rods 21 into the mobile trolley 1. A lateral detection component 22 is fixedly installed at one outer end of the rods 21. The lateral detection component 22 includes a fixing plate 221 fixedly connected to the rods 21. Sliding plates 223 are provided on both sides of the fixing plate 221 and are slidably connected. The top detection device 3 includes multiple arc-shaped plates 32, which are mutually fitted and slidably connected. Several nozzles are fixedly installed on the periphery of the arc-shaped plates 32 and on the sides of the fixing plate 221 and the sliding plate 223.

[0023] Specifically, by setting up a lateral detection device 2 and a top detection device 3, both the lateral detection device 2 and the top detection device 3 can slide and adjust their own positions, so that the nozzles installed on their surfaces can be moved to a position relatively close to the tunnel wall. Spraying after getting close can reduce the loss of reagents caused by drifting in the air.

[0024] Both the lateral detection device 2 and the top detection device 3 can be deployed near the tunnel wall. Combined with the design of multiple nozzles, this allows for simultaneous spraying of a ring of tunnel walls, thereby increasing the efficiency of reagent spraying.

[0025] The side of the mobile trolley 1 is provided with a slot 11 that matches the insertion rod 21. The inner wall of the slot 11 is provided with a first T-shaped groove 12. The side of the insertion rod 21 is fixedly connected with a first T-shaped rod 211 that matches the first T-shaped groove 12. The end of the mobile trolley 1 is provided with an adjustment device 4 for controlling the sliding of the two insertion rods 21 relative to each other.

[0026] Specifically, the insertion rods 21 slide interlaced within the slot 11, thereby causing the lateral detection devices 2 to slide away from the sidewalls near the tunnel. The cooperation between the first T-shaped rod 211 and the first T-shaped slot 12 improves the stability of the insertion rods 21 during sliding.

[0027] Each of the two insert rods 21 has a receiving cavity 212 on the side that is close to each other. A gear 41 is installed in the receiving cavity 212. The adjusting device 4 includes a knob 42 that is rotatably connected to the moving trolley 1. The end of the knob 42 extends into the receiving cavity 212 and is fixedly connected to the gear 41. A rack 213 that meshes with the gear 41 is fixedly connected to the inner wall of the receiving cavity 212.

[0028] Specifically, gear 41 is rotatably disposed in receiving cavity 212. Knob 42 drives gear 41 to rotate. Under the action of rack 213, it drives two insert rods 21 to slide interlaced, thereby realizing that the lateral detection components 22 slide closer or further apart.

[0029] A second T-shaped groove 222 is provided on the top of one side of the fixed plate 221 and the bottom of the other side, on the top of one side of the sliding plate 223 and the bottom of the side of the other sliding plate 223. A second T-shaped block 224 matching the second T-shaped groove 222 is also fixedly connected to the sides of the fixed plate 221 and the sliding plate 223. A bolt 225 is rotatably connected to the top of the fixed plate 221. The end of the bolt 225 extends into the second T-shaped groove 222 and passes through the second T-shaped block 224. The bolt 225 is threadedly connected to the second T-shaped block 224. A spring 226 is sleeved on the periphery of one end of the bolt 225 in the second T-shaped groove 222. The two ends of the spring 226 are fixedly connected to the second T-shaped groove 222 and the second T-shaped block 224, respectively.

[0030] Specifically, the cooperation between the second T-shaped groove 222 and the second T-shaped block 224 allows one of the sliding plates 223 to slide upward and the other sliding plate 223 to slide downward, thereby matching the height of the tunnel sidewall and simultaneously spraying reagents onto the tunnel sidewall.

[0031] The top of the mobile trolley 1 has a cavity 13, which includes a strip groove 132. The top of the strip groove 132 has an arc groove 131. A lifting plate 31 is slidably connected inside the strip groove 132. A connecting rod 33 is rotatably connected between the arc plate 32 and the lifting plate 31.

[0032] Specifically, the lifting plate 31 moves upward, causing the arc plate 32 to move upward synchronously. The design of the arc groove 131 allows the arc plate 32 to unfold under the limitation of the arc groove 131, so as to spray the reagent on the top of the tunnel at the same time.

[0033] On the side of the arc-shaped plates 32 that are close to each other, there are respectively a limiting groove 321 and a limiting block that cooperates with the limiting groove 321. The side of the lifting plate 31 is fixedly connected with a third T-shaped block 311. The inner wall of the strip groove 132 is provided with a third T-shaped groove 133 that matches the third T-shaped block 311.

[0034] Specifically, the limiting block, in conjunction with the limiting slide 321, guides the distance and direction of the interlacing sliding of the arc-shaped plates 32. The limiting slide 321 has an arc-shaped structure, and an electric telescopic rod 34 is provided at the bottom of the strip groove 132. The two ends of the electric telescopic rod 34 are fixedly connected to the lifting plate 31 and the limiting slide 321, respectively.
