Description

Auxiliary device for wellhead hoisting operation Technical Field The utility model relates to the technical field of wellhead hoisting, in particular to an auxiliary device for wellhead hoisting operation. Background In construction scenes such as municipal works, hydraulic engineering and the like involving pipeline laying, the hoisting operation of culverts is a key link. At present, when the existing wellhead hoisting device is used for hoisting a culvert pipe, a plurality of problems exist. The hoisted culvert pipe and the culvert pipe laid in the lower part in the well are difficult to accurately align, and constructors often need to consume a great deal of time and effort to adjust, so that the construction efficiency is seriously affected. Some wellhead hoisting devices are provided with guides for assisting in the alignment of the culverts, but these guides are mostly of a fixed form. When the upper culvert pipe is contacted with the fixed guide device in the falling process, the guide device can cause severe collision on the top of the lower culvert pipe due to lack of the buffer structure. The severe collision not only can cause the top of the culvert pipe below to be damaged and damage the structural integrity of the culvert pipe, but also can cause the serious insufficient tightness of the joint of the two culvert pipes, so that the problems of leakage and the like occur in the later use process, and the normal operation of the whole pipeline system is affected. More seriously, when the guide device collides with the top of the lower culvert pipe, a larger impact force is generated. The impact force can be transmitted to the expansion mechanism for hoisting the upper culvert pipe, so that the support and fixing effect of the expansion mechanism on the upper culvert pipe is loose, and even the upper culvert pipe can be caused to fall off from the hoisting device, so that serious safety accidents are caused, and life safety of constructors and engineering property loss are threatened.
