Hydraulic rock splitter

Abstract

The invention discloses a hydraulic rock splitter which comprises a hydraulic cylinder body, a piston rod, a sealing block, a connector, a splitting block, a wedge block, a spring and a handle. The hydraulic cylinder body is composed of a hydraulic cylinder barrel and the connector, and the hydraulic cylinder body is sealed through the connector and a sealing piece. A force transmission device of the splitter is composed of the piston rod and the wedge block, and the piston rod and the wedge block are matched through a cylindrical hole and a cylinder and connected through a fastening screw. A sealing guide device of the piston rod is composed of a piston rod guide sleeve, an O-type sealing ring and an ASW-type dustproof ring which are mounted in an inner hole of the sealing block. A motion part of the splitting block is composed of the connector, the wedge block, the spring and the splitting block. The splitting block is mounted in a T-shaped groove of the connector. The inclined plane of the wedge block is attached to the inclined plane of the splitting block. The hydraulic rock splitter has the beneficial effects of being uniform in part stress, small in equipment abrasion, high in durable degree, convenient to take, high in decomposition efficiency and little in early preparation work, and is suitable for secondary decomposition of exploited granite and large rock, and the cleanliness and yield of stone can be effectively improved.

Description

technical field [0001] The invention relates to a rock hydraulic splitting machine, in particular to a hydraulic splitting machine suitable for secondary decomposition of granite and other rocks and stone mining. Background technique [0002] At present, the main methods of domestic rock decomposition are blasting and breaking hammer decomposition. With the acceleration of national infrastructure, these two methods are greatly restricted and cannot be used under certain conditions. Therefore there is a need for an efficient quarrying method to meet the usage requirements when they cannot be used. [0003] Due to its small size, simple equipment, easy movement, and unlimited use locations; the static pressure is released slowly during work, safe and reliable, no noise, no pollution to the environment, short time to decompose rocks, high efficiency, and rock mining relatively tidy. It can be widely used in stone mining, urban tunnel construction and demolition of buildings....

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to design a more reasonable mechanical and hydraulic structure so that the bonding plane of the splitting block and the wedge block will not change when the splitter is working, and reduce equipment damage caused by friction and extrusion. damage; design the force transmission structure to make the force transmission uniform and reduce deformation; use the spring to provide the effect of splitting the return stroke, so that the return position is accurate
