Embodiment 1

[0039] Underground cables are more and more widely used in urban construction due to their advantages such as high safety, beautiful appearance, and small footprint. In the area where underground cables are laid, a cable shaft will be set up at intervals to facilitate the inspection and maintenance of cables. The cable well is covered with a well cover, and the well cover is opened to enter the cable well for operation. Open holes are reserved on the well covers. The setting of the open holes can ensure that the air pressure in the underground pipeline is the same as that of the outside world, and on the other hand, it is convenient for the lifting tool to stretch into the open holes to lift the well cover. The manhole cover lifting operation is a necessary step for cable inspection and maintenance. The cable lifting device in the prior art has high requirements for installation space and cannot be applied to the manhole cover lifting on uneven ground. It is inconvenient to ho...

Embodiment 2

[0060] The lifting device provided in this embodiment is basically the same as the lifting device provided in Embodiment 1, the difference is that: the casing 321 is provided with a stopper, which can fix the casing 321 at a certain position on the lifting rod 310 to prevent the casing from 321 slides at will, which affects the lifting stability. In this embodiment, the stopper is a bolt, and the side wall of the casing 321 is provided with a through threaded hole, and the bolt can be screwed in and out of the threaded hole. When the bolt is screwed into the threaded hole, it can abut against the lifting rod 310, effectively preventing the sleeve 321 from sliding on the lifting rod 310; when the distance between the two hooks 322 needs to be adjusted, the bolt is loosened, and the sleeve 321 can Slide along the lifting rod 310 to the desired position. It should be noted that the selection of the stopper is not limited to bolts, and stoppers of other structures can also be use...

Abstract

The invention relates to the technical field of electric power overhaul equipment, and discloses a hoisting device. The hoisting device comprises two frame body assemblies, hoisting assemblies and a hanging assembly, the two frame body assemblies are arranged at intervals, each frame body assembly is provided with one hoisting assembly, the hanging assembly comprises a hoisting rod and two hanging pieces, the two ends of the hanging assembly are connected with one set of hoisting assemblies respectively, the hoisting assemblies are configured to adjust the height of the hoisting rod, and the two hanging pieces are movably arranged on the hoisting rod and can be close to or away from each other. The two hoisting assemblies are arranged to adjust the heights of the two ends of the hoisting rod correspondingly, the hoisting rod can be in an inclined state, and a well lid which is obliquely installed can be conveniently and stably lifted. In addition, the two hanging pieces are movably arranged on the hoisting rod and can be close to or far away from each other, so that the hanging pieces can adapt to well lids of various sizes, and the universality of the hoisting device is improved.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance equipment, in particular to a lifting device. Background technique [0002] With the development of the economy and the rapid development of urbanization, underground cables gradually replace the fixed wires of the electric frame, and more and more underground cables are laid in cities. The area where cables are laid is called a cable corridor. Generally speaking, a cable well is set at every interval, and the cable well must use a cable well cover. When doing underground cable work in cities, it is necessary to open the cable manhole cover first, and some cable manhole covers are in disrepair for a long time. When it comes to planned work and maintenance, the opening and transfer of these cable manhole covers is very labor-intensive, which affects work efficiency and brings hidden safety risks. [0003] At present, there are three ways to lift the cable manhole cover. One is ...
