Problems solved by technology

During the impact process, the greater the impact stroke, the better the rock-breaking effect. However, due to the greater the falling stroke during the impact, the greater the tension of the wire rope on the equipment, or the occasional empty smashing of the equipment due to other reasons, the wire rope The pulling force will also be greatly increased
The current equipment is often limited by insufficient cushioning, and the impact force of the drop should not be too large, otherwise it is easy to cause damage to the equipment

Abstract

The invention provides a large stroke impact buffer device and impact crushing equipment, belonging to the technical field of geotechnical engineering. The large-stroke shock buffer device includes a base frame, a buffer cylinder, a winding device, a tower, an impact cylinder, a bracket and a rope. One end of the buffer oil cylinder is connected with the bottom frame, the other end of the buffer oil cylinder is connected with a first guide pulley, a relief valve is arranged on the buffer oil cylinder, the winding device is set on the bottom frame, the tower is set on the top of the bottom frame, and the impact cylinder is The top is connected to the top of the tower, the bottom end of the impact cylinder is provided with a second guide pulley, the bottom of the bracket is connected to the top of the chassis through a buffer spring, the bracket is located below the second guide pulley, and one end of the rope is connected to the winding device , the other end of the rope is connected with the impact hammer after passing through the first guide pulley and the second guide pulley in turn; wherein, when the pressure of the rope on the first guide pulley is greater than the preset value, the relief valve is opened to make the buffer cylinder shrink . Improved the buffering effect of rock breaking impact.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a large-stroke impact buffer device and impact crushing equipment. Background technique [0002] In geotechnical engineering, trenching and grooving are often required. For hard rock construction, impact equipment is the most efficient. During the impact process, the larger the impact stroke, the better the rock breaking effect. However, due to the impact, the greater the falling stroke, the greater the wire rope tension on the equipment, or the occasional empty smashing phenomenon caused by the equipment due to other reasons. The pulling force will also be greatly improved. The current equipment is often subject to insufficient buffering, and the impact force cannot be too large, otherwise it is easy to cause damage to the equipment. SUMMARY OF THE INVENTION [0003] The invention aims to improve the buffering effect during rock breaking impact. [0004] In...
