[0003] Since the trolley is mostly used inside the tunnel, a certain amount of dust may be generated during use, and then the dust spreads in the surrounding environment. In order to better carry out subsequent construction, it is necessary to reduce the surrounding dust. Therefore, liquid is sprayed through the pipes on the trolley to achieve dust reduction in the surrounding environment. However, most of the current pipes are fixed to the trolley by bundling, which is not only time-consuming and labor-intensive, but also difficult to adjust the angle of the pipe, and is not practical.

[0022] When in use, the entire trolley is moved to the designated position by means of the movable wheels 16, and then the plug block 5 is plugged and connected to the top of the second frame 2, and then the pipe to be used is clamped and connected to the inner side of the clamp block 10 for convenient subsequent use. Before each working cycle, the rails must be checked to see if they are straight, whether the center distance of the rails is aligned with the center distance of the lining, and to check the firmness of the rails. Before the trolley is in place, the rails must be laid straight to prevent the gantry support jack from failing to support the rails.
[0023] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the first frame 1 is welded to the second frame 2, and the top of the second frame 2 is provided with a slot 3, the slots 3 are equidistantly distributed at the top of the second frame 2, and the positioning holes 4 penetrate the inner side of the slots 3, one side of the slots 3 is connected with the positioning holes 4, an insert block 5 is distributed above the slot 3, and a guide groove 6 is provided on the upper surface of the insert block 5, a guide rod 7 penetrates the inner side of the guide groove 6, and a first spring 8 is sleeved on the outer surface of the guide rod 7, one end of the first spring 8 is fixedly connected to a guide sleeve 9, and a clamping block 10 is fixedly installed on the top of the guide sleeve 9, and the clamping block 10 is connected to the guide rod 7 through the guide sleeve 9 A sliding connection is formed, and the clamping block 10 is symmetrically distributed along the vertical center line of the plug block 5. An arc groove 11 is opened on the side wall of the clamping block 10. A positioning structure is arranged on the inner side of the bottom of the plug block 5. The positioning structure comprises a second spring 12, a positioning rod 13 and an auxiliary slide plate 14. The second spring 12 is fixedly connected to the inner side of the plug block 5, and the other end of the second spring 12 is fixedly connected to the positioning rod 13. The positioning rod 13 is slidably connected to the plug block 5 through the second spring 12, and the outer diameter of the positioning rod 13 is adapted to the inner diameter of the positioning hole 4. An auxiliary slide plate 14 is sleeved on the outer side of one end of the positioning rod 13.
[0024] When the plug block 5 is input into the inner side of the slot 3, the pressure applied to the positioning rod 13 disappears, and then the reverse force generated by the deformation of the second spring 12 will push the positioning rod 13 laterally, and then one end of the positioning rod 13 will be input into the inner side of the positioning hole 4, so as to realize the quick connection between the plug block 5 and the second frame 2. At the same time, when the positioning rod 13 moves laterally, it will drive the auxiliary slide plate 14 to slide laterally on the inner side of the plug block 5, so as to improve the stability of the positioning rod 13 during the lateral movement and prevent it from being offset in position, and then the pipeline is input into the two clamping blocks 10. Then, under the action of the pipeline, the clamping block 10 will be pushed laterally, and the clamping block 10 will drive the guide sleeve 9 welded at the bottom thereof to slide laterally along the guide rod 7. When the guide sleeve 9 slides laterally, the first spring 8 will be deformed accordingly to generate a reverse force, and then the reverse force will be used to realize the lateral reset of the clamping block 10 driven by the guide sleeve 9, so that the clamping blocks 10 moving toward each other on both sides are used to clamp and limit the pipeline, so as to ensure the stability of the pipeline itself when in use, and facilitate subsequent disassembly and other processing, which is convenient and fast, and has higher practicality;
[0025] Specific working principle:
[0026] When in use, the entire trolley is moved to the specified position by using the provided moving wheels 16, and then the plug block 5 is plugged and connected to the top of the second frame 2. When the plug block 5 is input into the inner side of the slot 3, the pressure applied to the positioning rod 13 disappears, and then the reverse force generated by the deformation of the second spring 12 will push the positioning rod 13 laterally, and then one end of the positioning rod 13 will be input into the inner side of the positioning hole 4, so as to realize the quick connection between the plug block 5 and the second frame 2. At the same time, when the positioning rod 13 moves laterally, it will drive the auxiliary slide plate 14 to slide laterally on the inner side of the plug block 5, so as to improve the stability of the positioning rod 13 during the lateral movement and prevent it from being offset in position, and then the pipeline is input into the two clamps. The clamp block 10 is pushed horizontally under the action of the pipeline, and the clamp block 10 drives the guide sleeve 9 welded at the bottom thereof to slide horizontally along the guide rod 7. When the guide sleeve 9 slides horizontally, the first spring 8 is deformed and generates a reverse force. Then, the reverse action is used to realize the lateral reset of the clamp block 10 driven by the guide sleeve 9, so that the clamp blocks 10 moving toward each other on both sides are used to clamp and limit the pipeline, so as to ensure the stability of the pipeline during use, and facilitate subsequent disassembly and other processing, which is convenient and fast, and has higher practicality. Before each working cycle, it is necessary to check whether the rails are straight, whether the center distance of the rails is aligned with the center distance of the lining, and to detect the firmness of the rails. Before the trolley is in place, the rails must be laid straight to strictly prevent the phenomenon that the gantry support jack cannot be supported on the rails.
