Description

Wellhead pipeline winding and unwinding auxiliary device

Technical Field

The utility model relates to the technical field of dredging auxiliary equipment of drainage pipelines, in particular to a wellhead pipeline retraction auxiliary device.

Background

Along with the gradual perfection of the construction of urban drainage systems in China, dredging of the drainage systems becomes an important part of the field of urban drainage systems. The key points of dredging operation of the urban drainage system are key nodes which are easy to accumulate and are easy to accumulate, such as inspection wells, grit chambers, canal boxes, pump stations and the like. In the past, when the key node of the drainage pipe network carries out dredging operation, dredging equipment such as a mortar pump, a dredging vehicle or a dredging robot is needed, and the equipment is provided with a dirt sucking pipe and a cable with different thickness, and the dirt sucking pipe and the cable are easy to scratch with a wellhead wall in the process of lifting and descending the dredging equipment, so that the dirt sucking pipe and the cable are easy to damage over time.

In order to solve the problems, the Chinese patent application published under application number CN117550431A discloses a drag reduction bracket for pipeline wellhead construction, which comprises two first supporting rods, a guide wheel, a fixing seat and a transmission mechanism, wherein a connecting mechanism is arranged between the two first supporting rods and used for adjusting the distance between the two first supporting rods, the guide wheel is detachably arranged between the two first supporting rods and used for guiding a construction cable, the fixing seat is arranged on the first supporting rods and provided with a mounting mechanism for mounting and fixing the guide wheel, and the transmission mechanism is arranged in the fixing seat and used for driving the mounting mechanism and the guide wheel to move. The support can avoid abrasion of the well wall and the cable to a certain extent, but the drag reduction support needs to be installed at the well head through the two first support rods, and the structure is only suitable for the well head with the protruding part, and other forms of well heads need to be fixed with the well head through the second support rods with more complexity. The dredging robot is more used in large-pipe-diameter dredging scenes, such as a canal box, a pump station and the like, the traditional drag reduction support is inconvenient to install in the scenes, and because cables of the dredging robot comprise power supply and communication cables, and a sewage suction pipe is a 100mm plastic pipe, water is contained in the dredging robot during operation, in order to avoid the spool sinking into the bottom to be rolled by the robot, a floating ball is bound on the spool, and the dredging robot floats on the water surface. In the robot hoisting process of dredging operation by using the dredging robot, the guiding support of the existing single guiding wheel is easy to clamp and can not be successfully retracted in the robot hoisting process of dredging operation by using the dredging robot, so that the labor intensity of operators is increased, and the hoisting operation efficiency of the robot is affected.
