[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0020] See also Figures 1 to 4, an auxiliary device for extending and storing the circulating mud pipeline of a top shield machine, comprising a plurality of pipe clamps 3, a slide rail 1 fixedly arranged on the top of a shield machine trolley 5, a suspension rod 2 whose upper end is freely slidably suspended on the slide rail 1 and whose lower end is hinged to the middle of the pipe clamp 3; wherein the circulating mud pipeline 4 is a hose, and a plurality of the pipe clamps 3 are sleeved with the circulating mud pipeline 4 at the same interval along the length direction of the circulating mud pipeline 4, and the circulating mud pipeline 4 has a free bending portion 401 between adjacent pipe clamps 3;

[0021] In the above structure, the pipe clamp 3 can be made of a section of hard straight pipe, and its purpose is to fix the circulating mud pipe 4 to reduce the bending of the mud pipe, thereby preventing the pipeline from being poorly discharged or damaging the pipeline due to excessive resistance; the length and number of the pipe clamp 3 can be reasonably determined according to the on-site construction conditions; the setting of the free bending part 401 can make the circulating mud pipe 4 at the position of the adjacent pipe clamp 3 bend; because the pipe clamp 3 is hinged to the suspension rod 2, the pipe clamp 3 and the circulating mud pipe 4 at this position can rotate freely, and at the same time, the upper end of the suspension rod 2 is freely slid and hung on the slide rail 1, Thereby, the suspension rod 2 can drive the pipe clamp 3 and the circulating mud pipe 4 at that position to move freely along the slide rail 1; therefore, when the utility model device is used to carry out pipe jacking, shield jacking and shield construction in the tunnel, a plurality of suspension rods 2, pipe clamps 3 and slide rails 1 can be used to cooperate to realize that part of the circulating mud pipe 4 can be coiled and stored in the shield machine trolley 5 along the construction direction, and the circulating mud pipe 4 can also be directly pulled to extend it; in addition, a part of the circulating mud pipe 4 can be reserved at the tail of the equipment as a free hose for connecting the mud processing equipment, and the length of the free hose can be determined according to the actual situation; in summary, please refer to Figure 2 When the equipment is in the jacking condition, the circulating mud pipeline 4 connected to the utility model can be stretched to facilitate and quickly extend the working length of the circulating mud pipeline 4, thereby preventing the construction period from being stagnant due to the extension of the pipeline during the jacking process, and avoiding the problem of pipeline damage due to poor pipeline slag discharge or excessive slag discharge resistance; please refer to Figure 1 When the equipment is in a stopped state, the circulating mud pipeline 4 connected to the utility model can be retracted so that the circulating mud pipeline 4 can be regularly coiled and stored in the trolley, thereby preventing a large number of pipelines from piling up and occupying the tunnel construction space.

[0022] Although the pipe clamp 3 is made directly of a section of rigid straight pipe to save costs, when the circulating mud pipe 4 is inserted into or pulled out of the rigid straight pipe in turn, there will be a large friction between the outer wall of the circulating mud pipe 4 and the inner wall of the rigid straight pipe. Therefore, when multiple pipe clamps 3 are set, the installation and disassembly of the circulating mud pipe 4 will be more troublesome. In order to solve the above problem, further, in a preferred embodiment, the pipe clamp 3 includes a left pipe groove 301 and a right pipe groove 302 hingedly connected to the lower end of the suspension rod 2; the right pipe groove 302 is freely opened and closed and covers the left pipe groove 301, so that the circulating mud pipe 4 is fixed in the groove formed by the left pipe groove 301 and the right pipe groove 302; based on the above arrangement, the right pipe groove 302 can be directly opened, and the circulating mud pipe 4 can be directly engaged in the left pipe groove 301, and then the right pipe groove 302 and the left pipe groove 301 can be closed.

[0023] To facilitate the opening and closing of the right pipe groove 302 and the left pipe groove 301, further, in a preferred embodiment, one side of the left pipe groove 301 is hingedly connected to one side of the right pipe groove 302, and the other side of the left pipe groove 301 is detachably connected to the other side of the right pipe groove 302 via fasteners.

[0024] In order to reduce the weight of the left pipeline groove 301 and the right pipeline groove 302 to facilitate dragging of the pipeline clamp 3, further, in a preferred embodiment, the groove surfaces of the left pipeline groove 301 and the right pipeline groove 302 are hollow structures.

[0025] Furthermore, in a preferred embodiment, a slide groove 101 is provided in the slide rail 1 , and a pulley 201 slidably matched with the slide groove 101 is provided at the upper end of the suspension rod 2 .

[0026] Furthermore, in a preferred embodiment, the length of the free bending portion 401 is 0.8 to 2 m.
