In particular, the support panels are fixed to the underground pipe gallery 1 by means of expansion screws 31. The four suspension rods 32 are attached to four corners of the lower end surface of the support panel. The ratchet ring 34 includes a first ring and a second ring, an axis of the ratchet ring 34 extends in the front-rear direction, and the first ring is located on the front side of the second ring. Ratchet rings 34 are mounted to the lower ends of the four hanger bars 32. Specifically, a first ring is mounted to the lower ends of the front two hanger rods 32 and a second ring is mounted to the lower ends of the rear two hanger rods. The ratchet bar 341 includes a ring and a ratchet disposed on the ring. The two ratchet racks 341 are respectively mounted on the inner sides of the first ring and the second ring.
The outer ring 37 and the inner ring 38 are located between the first and second rings, and the inner ring 38 is located inside the outer ring 37. The axes of the outer ring 37 and the inner ring 38 extend in the front-rear direction, and preferably, the inner ring 38 may be concentric with the ratchet ring 34, and the outer ring 37 may be concentric with the ratchet ring 34.

Each stopper 39 has a through hole, and the control rod 36 also passes through the through hole of the stopper 39. The limiting teeth are matched with the ratchet bars, so that the ratchet bars can be tightened only and cannot be contracted, and the limiting teeth are matched with the ratchet bars, so that the ratchet bar fixing device is simple in structure, firm in limiting and easy to operate.
In this embodiment, the stop device further comprises a threaded sleeve 33, the threaded sleeve 33 being threadedly mounted to the control rod 36. When the pipeline needs to be disassembled, the thread sleeve 33 is rotated to press the limiting block 39 downwards, the outer side face of the limiting block 39 is pressed to the inner side face slightly exceeding the ratchet bar 341, the control rod can be rotated in the direction of opening the contraction device, and the pipeline can be disassembled smoothly at this time. After the disassembly is completed, the threaded sleeve 33 is rotated to make the limiting block return to the position where the limiting block is matched with the ratchet bar 341 again under the action of the return spring 310. The disassembly is simple, and the labor and the time cost are saved.
In this embodiment, the number of the control rods is 3, the number of the contraction devices is 6, and the number of the limiting blocks is 3.
