Technical Field

[0001] The utility model relates to the technical field of tunnel shield construction, in particular to a grouting pipe hanging device. Background Art

[0002] In order to provide residents with more convenient travel, various regions have actively carried out subway construction, among which shield tunneling is the mainstream construction technology for current subway construction.

[0003] For example, the patent with publication number CN214007236U provides a grouting pipe hanging device, which relates to the field of tunnel shield construction technology, including a rolling assembly, a blocking assembly, a first connecting structure and a second connecting structure; one end of the rolling assembly is connected to the first connecting structure, the other end of the rolling assembly is connected to one end of the blocking assembly, the other end of the blocking assembly is connected to the second connecting structure, the first connecting structure and the second connecting structure are respectively connected to the fixed pipe segment, the grouting pipe is placed on the rolling assembly, the blocking assembly is used to stop the grouting pipe laterally to prevent the grouting pipe from falling off, the blocking assembly cooperates with the rolling assembly to fix the grouting pipe on the pipe segment, so that the grouting pipe is fixed firmly and stably. At the same time, the rolling assembly can make the grouting pipe more convenient and labor-saving when moving along the construction direction. During the grouting process, it can slow down the shaking of the grouting pipe caused by the flow of slurry to a certain extent.

[0004] However, during use, this device cannot adapt to grouting pipes of different sizes due to its fixed connection structure.

[0006] In view of the shortcomings of the prior art, the utility model provides a grouting pipe hanging device, which has the advantages of reducing the wear on the grouting pipe, etc., and solves the problem that due to its fixed connection structure, it cannot adapt to grouting pipes of different sizes, and when the grouting pipe shakes, it will also cause it to rub against the above-mentioned device, thereby causing damage to the outer surface of the grouting pipe.

[0007] (II) Technical solution

[0008] The utility model solves the above-mentioned technical problems through the following technical solutions: a grouting pipe hanging device, comprising two mounting seats, each of which is fixedly connected to a mounting shell on the left side of each mounting seat, each of which is rotatably connected to a first rotating roller on the outer surface of each mounting shell, each of which is internally provided with an elastic component extending to the left side thereof, each of which is provided with a rotating shell on the left side of each elastic component, each of which is internally provided with a telescopic component, each of which is internally provided with a positioning component adapted to an adjacent telescopic component, each of which is internally provided with a common connecting shaft, and each of which is rotatably connected to a second rotating roller on the outer side of each connecting shaft.

[0009] The beneficial effects of the utility model are:

[0010] During use, the grouting pipe hanging device only needs to install one mounting seat first, and then place the grouting pipe above the first rotating roller, and then fix the other mounting seat to the wall. During this process, the other first rotating roller and the second rotating roller are made to fit tightly with the grouting pipe to complete the installation, which has the advantage of reducing wear on the grouting pipe.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the elastic component includes a telescopic shaft, a limit block, a spring and a connecting head.

[0013] The beneficial effect of adopting the above further scheme is that the telescopic shaft is pulled outward by the connecting head. During this process, the spring is deformed, thereby driving the first rotating roller and the second rotating roller to fit closely with the grouting pipe, thereby enhancing the support effect on the grouting pipe.

[0014] Further, the telescopic assembly includes an adjusting rod and an adjusting head, the interior of the rotating shell is slidably connected with the adjusting rod, the left side of the adjusting rod is fixedly connected with the adjusting head, and the interior of the adjusting head is hinged with the same connecting shaft;

[0016] The beneficial effect of adopting the above further scheme is that, first, by pulling the adjusting rod to make it slide inside the rotating shell until the adjusting rod is extended to an appropriate length, the positioning bolt can be rotated to drive the positioning block and the adjusting rod to fit tightly under the push of the thread, thereby achieving the effect of adapting to grouting pipes of different diameters.
