Automatic jacking and following hydraulic breaking hammer

Abstract

The invention discloses an automatic jacking and following hydraulic breaking hammer which comprises a hammer body with a steel chisel. A hammer shell with an opening in the right side is arranged onthe outer side of the hammer body; an automatic jacking and following device is arranged between the hammer body and the hammer shell, and comprises a clamping seat fixed to the right end of the hammer body and a buffering seat slidably connected to the left end of the hammer body; the clamping seat and the buffering seat are inserted onto two slide rails arranged in parallel in the left-and-rightdirection in a sleeving way; the two slide rails are respectively fixed onto the front-side inner wall and the rear-side inner wall of a conical shell; an elastic assembly is arranged between the buffering seat and the clamping seat; a hydraulic cylinder is arranged on the left side of the buffering seat; a piston rod of the hydraulic cylinder is abutted against the buffering seat; the hydrauliccylinder is fixed onto the left side wall of the hammer shell; and a check block is arranged at the right end of each slide rail and is fixedly connected with the hammer shell. The automatic jacking and following hydraulic breaking hammer provided by the invention can always keep the normal start oscillation and an excellent impact effect of the breaking hammer in the all-direction blowing and breaking process.

Description

technical field [0001] The invention relates to the technical field of breaking hammers, in particular to an automatic top pressure follow-up hydraulic breaking hammer. 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. However, when an ordinary breaker is equipped on an existing common excavator, the pre-jacking pressure and position adjustment of the breaker are all carried out through the stick oil cylinder. 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 consisten...

AI Technical Summary

Problems solved by technology

However, when an ordinary breaker is equipped with an ordinary excavator, the pre-pressing pressure and position adjustment of the breaker are all carried out through the arm cylinder.

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.
