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 buffering device and impact crushing equipment, and belongs to the technical field of geotechnical engineering. The large-stroke impact buffering device comprises a bottom frame, a buffer oil cylinder, a winding device, a tower, an impact oil cylinder, a support and a rope strip. 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, an overflow valve is arranged on the buffer oil cylinder, the winding device is arranged on the bottom frame, the tower is arranged on the top of the bottom frame, the top end of the impact oil cylinder is connected with the top of the tower, and a second guide pulley is arranged at the bottom end of the impact oil cylinder. The bottom of the support is connected with the top of the bottom frame through a buffer spring, the support is located below the second guide pulley, one end of the rope strip is connected with the winding device, and the other end of the rope strip sequentially passes through the first guide pulley and the second guide pulley and then is connected with an impact hammer. When the pressure of the rope strip on the first guide pulley is larger than a preset value, the overflow valve is opened to enable the buffer oil cylinder to contract. The buffer effect during rock breaking impact is improved.

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 trenching are often required, and impact equipment is most effective for hard rock construction. 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 improved. The current equipment is often limited by insufficient cushioning, and the impact force of the drop cannot be too large, otherwise it is easy to cause damage to the equipment. Contents of the invention [0003] The invention aims at improving the cushioning effect during rock-br...
