A manhole cover lifting device with a steering mechanism

Abstract

The invention discloses a manhole cover lifting device with a steering mechanism. The manhole cover lifting device comprises a base, sliding rods, the steering mechanism, a wire spool and a pulling rope. According to the manhole cover lifting device, the steering mechanism is arranged, so that the steering operation can be conveniently performed on a lifting appliance, the steering is accurate, and the angle of the lifting appliance after steering can be locked, so that the T-shaped lifting appliance does not need to be manually fixed from the relaxed state to the tightening state of the pulling rope, and the operating safety is increased; by adopting the structural design of an inner disk body and an outer disk body, the sliding rods on both sides can be synchronously pulled by both endsof the pulling rope, so that a manhole cover is stably lifted; and a rotating roller and a lifting support plate are arranged, so that the whole device flexibly moves, and the operating stability canbe guaranteed.

Problems solved by technology

[0003] Municipal construction projects involve urban sewage treatment. It is necessary to open the sewage manhole cover for pipeline cleaning. The hoisting holes on the manhole cover are all long strips, so the hoisting tool needs to be turned after the hoisting tool passes through the hoisting hole, so that the traction rope is tightened. When the spreader can conflict with the lower surface of the manhole cover, most of the existing manhole cover lifting devices are used to manually control the rotation angle of the spreader by feeling, which is troublesome to operate and the steering control is not accurate at the same time. In the process of loosening to tightening, it is necessary to manually fix the spreader to avoid its rotation, so there is a certain potential safety hazard
