DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Referring to Figures 1-4 The utility model provides two technical schemes:

[0024] The first embodiment: a shield tunnel grouting vehicle, comprising a grouting vehicle body 1, further comprising:

[0025] The grouting mechanism 2 is arranged on the rear side of the top surface of the grouting vehicle body 1 for grouting, the grouting mechanism 2 comprises a groove plate 27 fixedly installed on the rear side of the top surface of the grouting vehicle body 1, a plurality of sliding blocks 26 are slidingly installed on the top surface of the groove plate 27, and the plurality of sliding blocks 26 are linearly and uniformly distributed on the top surface of the groove plate 27, a pouring pipe 28 for grouting is fixedly installed on the top surface of the plurality of sliding blocks 26, and a material conveying assembly is arranged on the top surface of the grouting vehicle body 1 for conveying cement;

[0026] A limiting mechanism 3 is provided on the front side of several sliders 26 to fix the position of the casting pipe 28. The limiting mechanism 3 includes a connecting frame 37 fixedly installed on the front side of several sliders 26 to improve the stability when the sliders 26 slide. The connecting frame 37 has an L-shaped cross section. A positioning component is provided on the front side of the connecting frame 37 to fix the position of several sliders 26. The positioning component includes several fixing boxes 31 fixedly installed on the front side of the connecting frame 37. Several pull rods 32 are linearly and evenly distributed on the front side of the connecting frame 37. A limiting plate 34 is movably installed inside each of the fixing boxes 31. A plug rod 35 for fixing the position of the connecting frame 37 is fixedly installed on the rear side of the limiting plate 34. Several slots 36 are opened on the front side of the slot plate 27. A pull rod 32 for conveniently pulling the limiting plate 34 is fixedly installed on the front side of the limiting plate 34. The outer side of the pull rod 32 is movable. A spring 33 is installed to provide power to insert the rod 35 into several slots 36. The rear side of the inner cavity of the connecting frame 37 is in close contact with the front side of the slot plate 27. The front end of the pull rod 32 moves through the interior of several fixed boxes 31 and extends to the front side of several fixed boxes 31. When it is necessary to release the restriction on the connecting frame 37, simply pull the pull rod 32 to pull the rod 35 out of the several slots 36 and release the restriction on the connecting frame 37. The front end of the spring 33 is fixedly installed on the front side of the inner cavity of several fixed boxes 31, and the rear end of the spring 33 is fixedly installed on the front side of the limiting plate 34. The rear end of the rod 35 moves through the front side of the connecting frame 37 and extends into the interior of several slots 36. The elastic force of the spring 33 can drive the limiting plate 34 to insert the rod 35 into the interior of several slots 36 and fix the position of the connecting frame 37. The structure is simple and easy to operate. Since the connecting frame 37 and the slider 26 are a fixedly connected whole, when the insert rod 35 is inserted into the slot 36 opened on the slot plate 27, the position of the connecting frame 37 relative to the slot plate 27 is locked, thereby restricting the sliding of the slider 26 on the top surface of the slot plate 27 through the physical connection relationship, thus realizing the fixation of the spacing of the pouring pipe 28.

[0027] The spacing of the cement pouring is easily adjusted by the set insertion rod 35 and connecting bracket 37. When it is necessary to adjust the pouring spacing, pull the pull rod 32 to drive the limiting plate 34 to pull the insertion rod 35 out of the slot 36. At this time, pull the connecting bracket 37 to drive the pouring pipe 28 to move laterally to adjust its spacing. When the appropriate position is adjusted, release the pull rod 32, and then the elastic force of the spring 33 will push the limiting plate 34 to insert the insertion rod 35 into the slot 36. The position of the pouring pipe 28 is fixed by the connecting bracket 37. The adjustment is convenient and improves the working efficiency of the device.

[0028] The second embodiment differs from the first embodiment in that the material conveying assembly includes two mounting plates 24 fixedly installed on the rear side of the top surface of the grouting truck body 1. A mounting box 21 for temporary cement storage is fixedly installed on the top surface of the two mounting plates 24. A discharge valve pipe 23 for conveying cement is connected to the front side of the mounting box 21, and several distributing valve pipes 22 for distributing and conveying cement are connected to the rear side of the mounting box 21. These distributing valve pipes 22 are linearly and evenly distributed on the rear side of the mounting box 21. A flexible hose 25 is connected to the rear end of each distributing valve pipe 22. The front end of the discharge valve pipe 23 is connected to the outlet of the cement pipe in the grouting truck body 1, and the rear end of the flexible hose 25 is connected to the inlet of the pouring pipe 28. Opening the discharge valve pipe 23 allows cement to flow into the mounting box 21, and opening the distributing valve pipes 22 allows cement to flow into the flexible hoses 25 and enter the pouring pipe 28 for pouring, which is convenient and quick.

[0029] The installation box 21 and pouring pipe 28 facilitate the delivery of cement for pouring. When in use, open the discharge valve pipe 23 to let the cement flow into the installation box 21 for storage, then open the limit mechanism 3 and slide the slider 26 to fix the pouring pipe 28 in a suitable position, and then open the distribution valve pipe 22 to let the cement flow through the hose 25 and enter the pouring pipe 28 for pouring. It is convenient, quick and practical.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user pulls the lever 32 to move the limiting plate 34 and pull the insert rod 35 out of the slot 36. At this time, pulling the connecting bracket 37 can move the pouring pipe 28 laterally to adjust its spacing. When the spacing of the bricks is adjusted to a suitable position, the lever 32 is released. Then, the elastic force of the spring 33 will push the limiting plate 34 to insert the insert rod 35 into the slot 36. The position of the pouring pipe 28 is fixed by the connecting bracket 37. At this time, the discharge valve pipe 23 is opened to allow cement to flow into the installation box 21 for storage. Then, the distribution valve pipe 22 is opened to allow cement to flow through the hose 25 and enter the pouring pipe 28 for pouring.
