Lever type manhole cover opener

Abstract

The invention belongs to the technical field of pipeline maintenance devices, and particularly relates to a lever type manhole cover opener. The lever type manhole cover opener comprises an opener, asteel reinforcing rod, a rotating block, a hook, a lever and a lock sleeve, wherein the bottom of the opener is in threaded connection with the steel reinforcing rod, and the bottom of the steel reinforcing rod is in threaded connection with the hook; and the interior of the opener is connected to the lever in an inserted mode, and the inner wall of the circumference of the lever is buckled with the lock sleeve; and a groove channel is integrally formed in the inner wall of the circumference of the opener. According to the lever type manhole cover opener, the steel reinforcing rod with a hookat the lower part of the opener is inserted into a manhole cover hole, then the steel reinforcing rod is rotationally fixed with the circumferential inner wall of the manhole cover hole through hook arc grooves; after the hook below the opener is firmly fixed to a manhole cover, the steel reinforcing rod is to with a limiting frame through the lock sleeve on the lever in an inserted mode; the lever is pressed downwards, and a lever principle is used for applying force to the opener, so that the steel reinforcing rod below the opener is lifted; the opener is convenient to carry and convenient to use, the opening problem of the manhole cover is solved, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of pipeline maintenance devices, in particular to a lever-type manhole cover opener. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. It is called the inspection well, and the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well. Mainly, on the inspection well cover, it is generally necessary to indicate the purpose of the underground pipeline, the management unit and telephone number. [0003] The wellhead of the inspection well is usually covered with a manhole cover. Most of the traditional manhole covers are provided with a through hole. [0004] However, in actual operation, due to long-term use...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a lever-type manhole cover opener to solve the problem in the above-mentioned background technology that due to long-term use, part of the manhole cover is stuffed with sand and other sundries, which cannot be opened by manpower alone and needs to be repeatedly struck with a hammer. Manhole cover, if the manhole cover is loosened and taken out, it is more laborious, and if it still cannot be opened, it is necessary to use a hammer to destroy the plastic manhole cover. The repair and maintenance of the equipment in the well will cause frequent damage to the plastic manhole cover. For the staff who patrol a large area every day, use extremely inconvenient
