hydraulic breaker

Abstract

The utility model relates to a hydraulic breaking hammer, which is used for matching excavators, loaders, and roadway cleaning machines. The hammer body and the hammer shell are connected through a pressing device and a moving device. The front splint and the rear splint of the mobile device clamp the hammer body through bolts, and they are integrated with the hammer body. Roller shafts with rollers are symmetrically arranged on the outside of the front splint and rear splint. Groove track one; the front splint of the top pressure device has ear seat one, and the rear flange of the hammer shell has ear seat two. 1. The two ear seats are hinged. The invention has a simple and compact structure, is easy to process and manufacture, can ensure that the breaker can always vibrate normally for any strike direction and angle, and can realize automatic follow-up of the strike point distance, reducing the alignment of the mechanical arm and the adjustment of the crushing depth. Improve work efficiency. It is suitable for mining, pavement crushing, tunnel construction, building demolition construction and tunnel construction cleaning and risk removal operations.

Description

technical field [0001] The invention relates to the technical field of crushing equipment and tools, in particular to a hydraulic breaker that can be used for excavators, roadway cleaning machines, demolition machinery and equipment, etc., and can be automatically pressed and followed. Background technique [0002] With its advantages of large impact energy, fast frequency and high construction efficiency, hydraulic breakers are more and more used in mining, road breaking, tunneling, building demolition, etc. According to its structural principle, the hydraulic breaker can be divided into an ordinary impact breaker in which the piston and the steel drill rod are separated, and a kinetic energy breaker in which the piston and the steel drill rod are connected together. Its working principle is that the high-frequency, high-speed impact piston hits or drives the steel braze to impact and hit the target to make it break. For the target with dense combination, high strength and...

AI Technical Summary

Problems solved by technology

When striking downwards, under the action of the self-weight of the breaker, drill rod, bucket rod, moving rod, etc., the pre-jacking pressure and position adjustment requirements are basically the same, and the striking effect is better; while striking horizontally and upwards, due to the loss of self-weight Function, pre-jacking pressure and position adjustment requirements are not consistent, mainly because the pre-jacking pressure is insufficient. During use, the breaking hammer will work well when it hits downwards, but when the drill rod is horizontal and hits upwards, the breaking hammer will not vibrate. , The phenomenon of not being able to impact normally seriously reduces the work efficiency and affects the application expansion of the breaker, especially in the application of roadway breaking loose layer cleaning and building demolition.
