Manual quick changing device for working tools of roadway repairing machine and operation method thereof

Abstract

The invention discloses a manual quick changing device for working tools of a roadway repairing machine and an operation method thereof. The manual quick changing device comprises a connecting shell,a first pin shaft, a positioning block, a rotating device and a second pin shaft. The quick changing device is connected with a working arm of the roadway repairing machine through the second pin shaft, connected with an oil cylinder of the roadway repairing machine through the first pin shaft, and connected with a pin shaft of one working tool through a front J-shaped pin shaft clamping groove; and the quick changing device makes contact with the upper surface of an adaptive base of the working tool through the lower surface of a transverse baffle. A socket wrench is used for driving the rotating device to rotate, so that the positioning block slides in a guide groove in a reciprocating mode to realize rapid replacement of the working tools. The manual quick changing device is small in size, simple in structure, high in reliability, wide in application range and low in production and manufacturing cost, quick replacement of various working tools of the roadway repairing machine can beachieved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of roadway repair equipment, in particular to a manual quick change device for working tools of a roadway repair machine and an operating method thereof. Background technique [0002] In recent years, most coal mines at home and abroad have successively entered the deep mining stage, especially under the conditions of high ground stress, soft and broken coal rock, the roadway surrounding rock deformation is serious, the roadway repair machine is a coal mine roadway that integrates digging, digging, transportation and loading. Surrounding rock treatment construction equipment is more and more widely used, and users have higher and higher functional requirements for roadway repair machines. A variety of working tools are used for full-section construction, such as breakers, buckets, milling heads, hydraulic shears, hydraulic grippers, etc. The roadway repair machine equipped with a single working tool can no l...

Problems solved by technology

[0002] In recent years, most coal mines at home and abroad have successively entered the stage of deep mining, especially under the conditions of high ground stress, soft and broken coal rock, the roadway surrounding rock deformation is serious, the roadway repair machine is a coal mine roadway that integrates digging, digging, transportation and loading. Surrounding rock treatment construction equipment is more and more widely used, and users have higher and higher functional requirements for roadway repair machines. A variety of working tools are used for full-section construction, such as breakers, buckets, milling heads, hydraulic shears, hydraulic grippers, etc. The roadway repair machine equipped with a single working tool can no longer meet the job requirements

[0003] The current solution is mainly to use hydraulic quick-change devices. This solution usually uses the expansion and contraction of hydraulic cylinders to realize the replacement of equipment. The hydraulic cylinder is easily damaged, the reliability and stability are not high, and the applicable working tools are limited, and the manufacturing cost is high
