Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering maintenance technology, and in particular to a tunnel leakage repair device. Background Technology

[0002] As an important infrastructure in transportation, water conservancy, and municipal engineering, tunnels are located underground or semi-underground for a long time. Affected by factors such as groundwater infiltration, changes in geological structure, and concrete aging, they are prone to leakage problems. Tunnel leakage can not only corrode the internal steel structure and reduce the strength of concrete, but also cause slippery road surfaces, electrical equipment failures, and in severe cases, even tunnel collapse, threatening traffic safety and the lifespan of the project.

[0003] Currently, the core method for tunnel leakage repair is grouting. Commonly used equipment mainly consists of a mobile carrier, storage tank, grouting pump, and pipeline. Existing tunnel leakage repair equipment does not have an effective mud level detection device. The remaining mud in the storage tank depends entirely on the operator's visual observation or experience. Due to the dim lighting and complex working environment inside the tunnel, it is difficult for the operator to accurately grasp the remaining mud. Utility Model Content

[0004] The purpose of this utility model is to provide a tunnel leakage repair device, which aims to solve the technical problem in the prior art that it is difficult for operators to accurately grasp the remaining amount of mud due to the dim lighting and complex working environment inside the tunnel.

[0005] To achieve the above objectives, this utility model employs a tunnel leakage repair device, which includes a mobile trolley, a storage tank on the upper surface of the mobile trolley, and a cage frame fixedly installed on the inner wall of the storage tank. The cage frame contains a float body, and a float rod is fixedly installed above the float body, with the float rod penetrating the end cap of the storage tank. An L-shaped linkage rod is fixedly connected to the top of the float rod, and the L-shaped linkage rod slides within the limiting frame. A reading rod is fixedly installed at the top of the L-shaped linkage rod. The limiting frame is fixedly installed on the outside of the storage tank, and a scale is installed on the outside of the limiting frame.

[0006] The limiting frame has a mounting bracket on the side away from the scale. The mounting bracket has multiple screw holes on its surface, and a first limit switch and a second limit switch are threadedly connected to the outer surface of the mounting bracket.

[0007] The storage tank is mounted on the upper surface of the mobile trolley via a fixed base.

[0008] The storage tank end cap surface is connected to a feed pipe, and a pipe cap is detachably installed above the feed pipe.

[0009] The storage tank end cap is fixedly equipped with a motor, and the output end of the motor is equipped with a stirring blade, which is located inside the storage tank.

[0010] The discharge pipe of the storage tank is connected to a mud pump, and a check valve is installed inside the discharge pipe.

[0011] The output end of the mud pump is connected to a grouting pipe, and a placement plate fixedly connected to the mobile trolley is provided below the grouting pipe.

[0012] An indicator light is fixedly installed on the upper surface of the placement plate.

[0013] Compared with the prior art, this utility model has the following advantages: 1. Through the mechanical linkage structure of the float body, float rod, L-shaped linkage rod and scale, the change of mud level in the storage tank is converted into the intuitive displacement of the reading rod on the scale. There is no need to rely on the complex signal conversion of electronic sensors. Even in the harsh environment of dark tunnels with a lot of dust, the operators can accurately read the real-time mud level through the reading rod, realizing the visualization and precise control of the mud level.

[0014] 2. By using the first limit switch (low liquid level emergency threshold) and the second limit switch (low liquid level early warning threshold) on the mounting frame, combined with the graded prompts of the indicator lights, different material replenishment nodes can be preset according to the actual operation rhythm. This avoids damage to the mud pump due to sudden material interruption or interruption of grouting operation due to untimely material replenishment, thus ensuring maintenance continuity and equipment safety.

[0015] 3. The cage frame on the inner wall of the storage tank can limit the lateral sway of the float body, allowing it to rise and fall vertically with the liquid level only. This prevents the float from shifting due to mud disturbance caused by the movement of the trolley and the rotation of the agitator blades, ensuring the accuracy of liquid level monitoring. At the same time, the float body can effectively reduce the adhesion of high-viscosity mud and prevent the mud from solidifying and enveloping the float, further ensuring the stability and service life of liquid level monitoring.

[0024] In this embodiment, the storage tank 102 is disposed on the upper surface of the mobile trolley 101, and a cage frame 103 is fixedly disposed on the inner wall of the storage tank 102; a float body 104 is disposed inside the cage frame 103, and a float rod 105 is fixedly disposed above the float body 104, and the float rod 105 penetrates the end cap of the storage tank 102. An L-shaped linkage rod 106 is fixedly connected to the top end of the float rod 105, and the L-shaped linkage rod 106 slides within a limiting frame 107. A reading rod 124 is fixedly disposed on the top end of the L-shaped linkage rod 106, and the limiting frame 107 is fixedly disposed on the outside of the storage tank 102. The outside of the limiting frame 107 is provided with engravings. The scale 108 is used to measure the remaining amount of mud in the storage tank 102 for maintenance. The cage frame 103 restricts the float body 104. The float body 104 is hollow and coated with PTFE to reduce mud adhesion and prevent mud from enveloping the float. The float body 104 floats on the surface of the mud in the storage tank 102. The float body 104 drives the float rod 105 to adjust synchronously. The float rod 105 is slidably connected to the end cap of the storage tank 102. At the same time, the float rod drives the L-shaped linkage rod 106 to slide within the limiting frame 107. The remaining amount of mud in the storage tank 102 can be read by using the reading rod 124 in conjunction with the scale 108.

[0025] The limiting frame 107 has a mounting bracket 109 on the side away from the scale 108. The mounting bracket 109 has multiple screw holes 110 on its surface. A first limit switch 111 and a second limit switch 112 are threadedly connected to the outer surface of the mounting bracket 109. The first limit switch 111 and the second limit switch 112 are mounted on the surface of the mounting bracket 109 by bolts through the screw holes 110. When the reading rod 124 is parallel to the first limit switch 111 or the second limit switch 112, the first limit switch 111 or the second limit switch 112 is triggered.

[0026] Secondly, the storage tank 102 is mounted on the upper surface of the mobile trolley 101 via the fixing seat 113.

[0027] Meanwhile, the surface of the end cap of the storage tank 102 is connected to a feed pipe 114, and a pipe cover 115 is detachably installed above the feed pipe 114. The feed pipe 114 is used to transport the slurry into the storage tank 102, and the pipe cover 115 prevents the slurry from overflowing during the transportation process.

[0028] In addition, a motor 116 is fixedly installed on the surface of the end cap of the storage tank 102. A stirring blade 117 is provided at the output end of the motor 116. The stirring blade 117 is located inside the storage tank 102. The motor 116 drives the stirring blade 117 to rotate. The stirring blade 117 stirs the mud in the storage tank 102 to prevent the mud from solidifying inside the storage tank 102.

[0029] Secondly, the discharge pipe 118 of the storage tank 102 is connected to the mud pump 119, and a check valve 120 is installed in the discharge pipe 118. The mud pump 119 is used to transport mud in the storage tank 102, and the check valve 120 prevents mud backflow.

[0030] Meanwhile, the output end of the mud pump 119 is connected to the grouting pipe 121, and a placement plate 122 fixedly connected to the mobile trolley 101 is provided below the grouting pipe 121. The mud pump 119 outputs mud to the repair position through the grouting pipe 121, and the placement plate 122 is used to place the grouting pipe 121.

[0031] In addition, an indicator light 123 is fixedly installed on the upper surface of the placement plate 122. The indicator light 123 is equipped with a yellow light and a red light. When the second limit switch 112 is triggered, it indicates the first indication point of the remaining mud, and the yellow light of the indicator light 123 lights up. When the first limit switch 111 is triggered, it indicates that the remaining mud is almost gone, and the red light of the indicator light 123 lights up, reminding the operator to add mud.

[0032] Using a tunnel leakage repair device according to this embodiment, by setting up the mobile trolley 101, the storage tank 102, and the float body 104, in specific use, slurry is injected into the storage tank 102 through the feed pipe 114, and the pipe cover 115 covers the top of the feed pipe 114. At the same time, the operator fixes the second limit switch 112 to the mounting frame 109 according to the required bolts. The scale 108 can read the remaining amount of slurry when the second limit switch 112 is triggered. The first limit switch 111 is fixed to the bottom of the mounting frame 109. The motor 116 drives the stirring blade 117 to rotate to prevent the slurry in the storage tank 102 from solidifying, and pushes the mobile trolley 101 to the work site. The grouting pipe 121 is aligned with the repair position, the slurry pump 119 is run, and slurry is pumped into the tank. The mud is ejected through the discharge pipe 118, check valve 120, mud pump 119, and injection pipe 121. Simultaneously, the float body 104 descends synchronously with the mud level in the tank. The float rod 105 drives the L-shaped linkage rod 106 to slide within the limiting frame 107. When the reading rod 124 triggers the second limit switch 112, the yellow light of the indicator light 123 illuminates, indicating to the operator that the mud level has reached the set level. When the reading rod 124 triggers the first limit switch 111, the red light of the indicator light 123 illuminates, indicating to the operator that the mud level is low. At the same time, the operator can read the real-time mud level using the reading rod 124 and the scale 108, which effectively monitors the mud level and provides alerts based on the set level, enabling the operator to accurately control the mud level.

[0033] The above-disclosed embodiments are merely preferred embodiments of the tunnel leakage repair device of this utility model, and should not be construed as limiting the scope of the utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes according to the claims of this utility model still fall within the scope of the utility model.
