It is usually used in conjunction with a supporting trolley (referred to as the trolley) behind the shield machine. It is usually composed of a boring machine, a propulsion device, a cutter device, a support system and other parts. The shield machine usually needs to be repaired after long-term use, and the support structure is a vital component that provides support for the shield machine.

[0003] After searching, the existing patent (publication number: CN219967912U) discloses a pipeline maintenance support structure, including a support plate, support columns arranged at both ends of the top of the support plate, and arc support blocks arranged on both sides of the top of the support column.

The spacing adjustment structure includes a built-in cavity opened at the top of the support column and a first rotating rod arranged at one end inside the built-in cavity. The utility model sets a spacing adjustment structure, and drives the first rotating rod and the second rotating rod to rotate at the same time by rotating the rotating wheel to drive the movable block to move and the arc support block on its top to move, so as to change the position of the arc support block, adjust the spacing between the two arc support blocks, and expand the size of the groove body composed of the two arc support blocks, so that the groove body composed of the two arc support blocks can better accommodate larger-sized pipelines, thereby better supporting the pipeline and improving applicability.

[0004] However, the above solution does not have the function of adjusting the height according to the actual maintenance needs and the needs of the staff, which brings certain inconveniences to the maintenance work and affects the overall maintenance efficiency.

[0005] In view of this, the utility model proposes a shield machine maintenance support structure. Utility Model Content

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, the hydraulic rod drives the moving block to operate, so that the storage table fixed between the two moving blocks moves up and down, thereby achieving the effect of adjusting the height of the storage table. The operator can easily adjust the height of the supporting structure to adapt to terrains of different heights, thereby ensuring the smooth progress of maintenance work, reducing the time and workload required for adjusting the supporting structure, and improving construction efficiency.

[0028] Example 2

[0029] On the basis of Example 1, a preferred embodiment of the shield machine maintenance support structure provided by the utility model is as follows: Figures 1 to 5 As shown: a mounting plate 10 is fixedly connected between the two adjusting cylinders 7 on the corresponding sides, the adjusting cylinder 7 has a fixing effect on the mounting plate 10, and the top of the mounting plate 10 is fixedly connected with left and right opposite supporting blocks 11, and the mounting plate 10 has a fixing and supporting effect on the supporting blocks 11.

[0030] In this embodiment, a slide bar 12 is fixedly connected between two mounting plates 10 on corresponding sides, the mounting plates 10 fix the slide bar 12 , and left and right opposite buffer sliding blocks 13 are slidably connected to the outer sides of the slide bar 12 .

[0031] In this embodiment, the top of the buffer slider 13 is fixedly connected to the adjusting rod 14 , and the buffer slider 13 has a fixing effect on the adjusting rod 14 . The top of the adjusting rod 14 is rotatably connected to the outer side with a hinge frame 15 .

[0032] In this embodiment, the two articulated frames 15 are respectively fixedly connected to the left and right sides of the bottom end of the storage platform 9 , and the storage platform 9 plays a fixing role for the articulated frames 15 .

[0033] In this embodiment, a buffer spring 16 is fixedly connected between the two buffer sliders 13 in order to further improve the stability of the buffer spring 16 . The buffer spring 16 is sleeved on the outer side of the slide rod 12 .

[0034] In this embodiment, a damping rod 18 is fixedly connected to the top of the support block 11, and the support block 11 plays a fixed supporting role for the damping rod 18. The telescopic end of the damping rod 18 is fixedly connected to the bottom end of the storage platform 9 in order to further improve the stability of the storage platform 9.

[0035] Furthermore, the bottom end of the base plate 1 is fixedly connected with uniformly distributed universal wheels 17 .

[0036] The working principle and use process of the utility model are as follows: first, the hydraulic rod 4 is started, and the moving block 5 is driven to move up and down through the extension and retraction of the hydraulic rod 4, thereby driving multiple connecting rods 6 to move synchronously.

The operator can easily adjust the height of the supporting structure to adapt to terrains of different heights, thereby ensuring the smooth progress of the maintenance work and reducing the time required for adjusting the supporting structure. In order to reduce time and workload and improve construction efficiency, during the placement process of the shield machine, a certain vibration and impact force are generated on the storage platform 9, which causes the storage platform 9 to move downward to a certain extent, so that the articulated frame 15 moves synchronously, and further transmits through the adjusting rod 14 so that the two buffer sliders 13 move in opposite directions on the outside of the slide rod 12, and the buffer spring 16 contracts. After contracting to a certain extent, the buffer spring 16 rebounds through its own elastic force, thereby driving each component to reset. At this time, the internal friction force of the damping rod 18 can effectively slow down the rebound speed of the buffer spring 16, thereby achieving a buffering effect on the storage platform 9, thereby effectively absorbing and reducing these vibrations and impact forces, and reducing their impact on the supporting structure and mechanical components, thereby extending the life of the equipment.
