Operating mechanism for breakage of mine roadway

Abstract

The invention discloses an operating mechanism for breakage of a mine roadway. The operating mechanism is connected with a driving device, and comprises a breaking hammer, a rotating seat and a supporting arm, wherein the breaking hammer is mounted on the rotating seat; the rotating seat is mounted on the supporting arm in a pivoting way; the other end of the supporting arm is connected with the driving device; the rotating seat is vertical to the own rotating surface of the rotating seat relative to the rotating surface of the supporting arm; and the supporting arm comprises more than two sections of branch supporting arms which are connected sequentially in a pivoting way, and in the supporting arm, the branch supporting arm farthest away from the rotating seat is a far arm, the branch supporting arm closest to the rotating seat is a close arm, and the maximum rotating angle of the rotating seat relative to the far arm is not less than 180 degrees. According to the invention, the supporting arm comprises more than two branch supporting arms, so that the rotating angle of the breaking hammer relative to the far arm can reach more than 180 degrees, as a result, the operating range of the breaking hammer is greatly improved, the breaking hammer is convenient to operate in a long and narrow mine roadway, the positioning operation to the breaking hammer is simple, and the efficiency of breaking operation is improved.

Description

technical field [0001] The invention relates to a crushing mechanism, in particular to a crushing mechanism in a mine roadway. Background technique [0002] The prying trolley is used in the mining operation cycle of underground mines. After the blasting of the mine roadway, the broken and unstable pumice on the roof, bottom plate and two sides of the operation site must be removed to ensure the safety of on-site operators and equipment. The trolley is the automatic mechanical equipment used to remove these pumice stones and the like. The prying trolley usually includes a working mechanism for crushing, a chassis, and a hydraulic and electrical system that provides power source and control functions. Among them, the working mechanism for crushing is used for crushing in the mine roadway, and is a key component of the prying trolley. Since the mine roadway is a narrow and long space, and the supporting arm of the current working mechanism for crushing is an integral structu...

AI Technical Summary

Problems solved by technology

Since the mine roadway is a narrow and long space, and the supporting arm of the current working mechanism for crushing is an integral structure, the angle adjustment range of the crushing hammer is small, and very cumbersome operation steps are required to align the crushing position during crushing, which reduces the working efficiency. It is extremely low, and sometimes it is impossible to align the crushing position at all, so that the crushing effect is greatly reduced, and the hammer is easily damaged

In addition, the breaker in the current working mechanism for crushing cannot perform translational movement, and it requires very cumbersome operations to translate to the next position after one position is broken, and the crushing effect of each position cannot be guaranteed.

Finally, the current working mechanism for crushing cannot swing relative to the prying trolley, which makes it very troublesome to adjust the angle of the breaking hammer, and cannot quickly and accurately perform crushing positioning
