Assembling and disassembling equipment used for sealing expansion cylinder of plugging machine and assembling and disassembling method for expansion cylinder

Abstract

The invention discloses assembling and disassembling equipment used for sealing an expansion cylinder of a plugging machine and an assembling and disassembling method for the expansion cylinder. The assembling and disassembling equipment comprises a shifting device and a lifting table device, wherein the shifting device comprises a horizontally arranged basal plate, a plurality of roller parts which are arranged at the lower side of the basal plate and are fixedly connected with the basal plate, and a hand-pushing part which is arranged at the upper side of the basal plate and is fixedly connected with one end of the basal plate; and the lifting table device is arranged on the basal plate, and comprises a horizontally arranged platen, a lifting jack assembly arranged between the basal plate and the platen, and a limiting slide path assembly arranged between the basal plate and the platen. The assembling and disassembling method for the expansion cylinder comprises a process of disassembling an old expansion cylinder and a process of mounting a new expansion cylinder. The assembling and disassembling equipment has the advantages of being simple in structure, convenient to operate, safe and reliable and high in practicability; the method has the characteristics of being high in efficiency, high in safety and small in labor intensity; and when the assembling and disassembling equipment used for sealing the expansion cylinder of the plugging machine is adopted to carry out assembling and disassembling operation on the expansion cylinder, the safety of operating personnel can be effectively improved.

Description

technical field [0001] The invention relates to a device for opening and closing a pipeline, in particular to a device for convenient loading and unloading of an expansion cylinder of a sealing machine, and a method for loading and unloading the expansion cylinder by using the equipment. Background technique [0002] The sealing machine is a kind of pipeline opening and sealing equipment, which is mainly used in the mechanical opening and cutting of pipelines. The expansion cylinder is an accessory device in the sealing machine, and the rubber on its outer surface is a vulnerable part and needs to be replaced frequently. Because the expansion cylinder itself is relatively heavy, the heavier one can reach more than one hundred kilograms, and the lighter one can reach tens of kilograms. This has just caused the disassembly and assembly operation of the expansion cylinder to be relatively complicated, and the risk is also relatively high. [0003] At present, when the loading...
