The lower side of the ear seat 3 is a conical surface structure, which is used in combination with a limiting plate 6. The cooperation enables the upper single-ring pull rod 1 to have greater displacement flexibility and adjustment range, and the structure is shown in detail in Figure 3 and Figure 4 .

[0039] The channel steel 4 is composed of two channel steels, and the lower part is welded with the spring group 5. The two channel steels in the channel steel 4 are reserved with a moving gap for the upper single ring pull rod 1. The channel steel 4 is used as a force balance structure to promote the synchronous operation of the multiple springs, balance the vibration and displacement generated in the operation process of the pipeline system, and ensure the stable operation of the pipeline system.

[0040] The spring group 5 contains multiple springs, each of which can bear a certain load and can move relatively freely to absorb the vibration and deformation of the pipeline system in the operation process. This structure can bear a large load, and the multiple springs can realize synchronous operation through the channel steel 4, which can avoid the failure of the pipeline system caused by the failure of a single spring. The spring group 5 is bolted with the existing steel structure below, which is convenient for disassembly.
