Manhole cover opening device for municipal public facility maintenance

Abstract

The invention discloses a manhole cover opening device for municipal public facility maintenance, and belongs to the field of municipal public facility maintenance. The manhole cover opening device comprises a vehicle base and a supporting box body, wherein one side of the upper portion of the vehicle base is connected with the supporting box body through screws, a rotating support is arranged atone side of the upper portion of the supporting box body, and the rotating support is welded to the supporting box body; a rotating disc is arranged in the rotating support, a vertical rod support iswelded to the middle of the upper portion of the rotating disc, and end face bearings are arranged at the upper end and the lower end of the rotating disc, so that it can be guaranteed that the vertical rod support can flexibly rotate in the rotating support when a well cover is hoisted, the well cover can be conveniently hoisted and moved away, and time and labor are saved; and by arranging flexible steel wire ropes between handheld handles and hanging rings, the angles of hooks can be conveniently adjusted at will, the hooks can conveniently and smoothly enter hanging holes in the upper portion of the well cover, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of municipal public facility maintenance, in particular to a inspection well cover opening device for municipal public facility maintenance. Background technique [0002] In recent years, with the unprecedented development of urban construction, the continuous laying of telecommunications, electric power, water supply and drainage pipelines, etc., the use of inspection wells is increasing. In order to be firm and anti-theft, inspection well covers are heavy in quality and tightly installed. The gap between the well and the manhole cover is often filled with impurities. When the manhole cover needs to be opened for pipeline maintenance or emergencies, it is often not opened immediately, and the work plan cannot be carried out on time, which seriously affects the work efficiency. Therefore, the inspection manhole cover is required. Uncapping device. [0003] However, during the use of the existing inspection well cover...

AI Technical Summary

Problems solved by technology

[0002] In recent years, with the unprecedented development of urban construction, the continuous laying of telecommunications, electric power, water supply and drainage pipelines, etc., the use of inspection wells is increasing. In order to be firm and anti-theft, inspection well covers are heavy in quality and tightly installed. The gap between the well and the manhole cover is often filled with impurities. When the manhole cover needs to be opened for pipeline maintenance or emergencies, it is often not opened immediately, and the work plan cannot be carried out on time, which seriously affects the work efficiency. Therefore, the inspection manhole cover is required. Opening device

[0003] However, during the use of the existing inspection well cover opening device, when the well cover is opened and removed, the rotational torque is large, and the operation is time-consuming and laborious. At the same time, most of the lifting components are composed of hard steel hooks, which are less flexible. It is inconvenient to insert the hanging hole on the well cover, and it takes a long time, and there is no special storage space for the operation and maintenance tools, and it is extremely inconvenient to use. Cover uncapping device, to solve the problems raised in the above-mentioned background technology
