Description

Technical Field

[0001] This utility model relates to the technical field of shield tunnel segment maintenance equipment, and in particular to an automatic spraying device for shield tunnel segment maintenance fluid. Background Technology

[0002] Demolded tunnel lining segments are the main assembly components in shield tunneling, forming the innermost barrier of the tunnel and bearing the responsibility of resisting soil pressure, groundwater pressure, and other special loads. The tunnel lining segments are the permanent lining structure of shield tunnels, and their quality directly affects the overall quality and safety of the tunnel, influencing its waterproofing and durability. After demolding, the segments require curing with a curing solution.

[0003] In the existing technology, when maintaining tunnel segments, the spraying coverage of the spraying device is relatively limited and it is inconvenient to adjust the angle of some nozzles. This limitation can easily lead to uneven distribution of the curing liquid on the surface of the segments, resulting in a reduction in the curing effect. Utility Model Content

[0004] This utility model mainly provides an automatic spraying device for shield tunnel segment curing fluid to improve the curing effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic spraying device for shield tunnel segment curing fluid, comprising an automatic spraying assembly, an adjusting assembly on the automatic spraying assembly, a circulation assembly at the bottom of the automatic spraying assembly, the automatic spraying assembly including a curing tank, spraying pipes installed on both sides of the curing tank, one end of each spraying pipe connected to a first delivery hose, the adjusting assembly including two moving slots, a support frame movably installed inside each moving slot, rotating shafts installed at both ends of the support frame, a spraying frame installed at one end of each rotating shaft, multiple nozzles provided on both the spraying pipes and the spraying frame, a rotating motor installed at one end of the support frame, and a threaded rod installed inside one of the moving slots. A translation motor is installed at one end of the tank. The first pump draws the curing fluid from the storage tank and delivers it through the first and second delivery hoses to the spray pipe and spray frame. The fluid is then sprayed out through nozzles to achieve the spray curing of the shield tunnel segments inside the curing tank. The translation motor electrically drives the threaded rod to rotate, which facilitates the movement of the support frame inside the moving tank and allows for lateral adjustment of the spray frame's position, thus increasing the spraying range. The rotation motor electrically drives one of the rotating shafts to rotate, which, in conjunction with the other shaft, allows for angle adjustment of the spray frame. This tilt adjustment avoids uneven spraying of the curing fluid caused by a fixed angle, ensuring that the curing fluid is evenly distributed on the surface of the tunnel segments, thereby improving the curing effect.

[0006] Preferably, the circulation component includes a filter box, a filter element installed inside the filter box, a sedimentation tank at the bottom of the filter box, and a connecting pipe connected to the top of the sedimentation tank. Excess seepage of maintenance liquid flows into the filter box, and the filter element helps to filter impurities and particulate matter in the maintenance liquid, causing the filtered maintenance liquid to flow into the sedimentation tank for sedimentation.

[0007] Preferably, a second delivery hose is connected to the side of the spray frame, a first pump is installed at one end of the second delivery hose, and a storage tank is installed at the bottom of the first pump. The operation of the first pump facilitates the extraction of curing liquid from the storage tank and delivers it to the inside of the spray pipe and the spray frame through the second delivery hose and the first delivery hose.

[0008] Preferably, a limiting frame is installed inside the filter box, the filter element moves within the limiting frame, sliding grooves are symmetrically installed on the side of the filter box, a sealing plate is movably installed inside the sliding groove, and a sealing gasket is installed on the side of the filter box. The filter element moves within the limiting frame, which facilitates maintenance and replacement of the filter element. The movable sealing plate moves within the sliding groove, which facilitates opening the filter box, and the sealing gasket helps to provide a sealing effect.

[0009] Preferably, a second pump is installed at one end of the connecting pipe. The second pump is located at the bottom of the storage tank. The second pump works to extract the maintenance solution that has undergone sedimentation treatment in the sedimentation tank, which is conducive to realizing the recycling of the maintenance solution and thus reducing the waste of the maintenance solution.

[0010] Preferably, the inner side of the curing box is provided with multiple sliding grooves, and a partition is movably installed inside the sliding groove. By moving the partition inside the sliding groove, the partition can facilitate the separation of the pipe segments and also make it convenient to replace the partition according to the size of the pipe segments.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the threaded rod is electrically driven by a translation motor to rotate, which facilitates the movement of the support frame inside the moving slot and allows for lateral adjustment of the position of the spray frame, thereby increasing the spraying range. The rotation motor electrically drives one of the rotating shafts to rotate, which, in conjunction with the rotation of the other shaft, facilitates the angle adjustment of the spray frame. This allows for tilt adjustment of the spray frame, avoiding uneven spraying of the curing liquid caused by a fixed angle, and ensuring that the curing liquid is evenly distributed on the surface of the tube segment, thus improving the curing effect.

[0013] 2. In this utility model, excess seepage of curing solution flows into the filter box. The filter element helps to filter impurities and particles in the curing solution, causing the filtered curing solution to flow into the sedimentation tank for sedimentation. The movable sealing plate moves inside the sliding groove, making it easy to open the filter box. The sealing gasket helps to provide a sealing effect.
