Small-amplitude tracking type breaking hammer

Abstract

The invention belongs to the technical field of breaking hammers, and particularly relates to a small-amplitude tracking type breaking hammer. The small-amplitude tracking type breaking hammer comprises a drill rod, a drill rod sleeve, a hydraulic knocking mechanism, a hydraulic control valve, clamp locking mechanisms and circular arc guide plates, wherein the drill rod is mounted inside the drill rod sleeve through the sliding cooperation of drill rod guide blocks and drill rod sleeve sliding holes; drill rod springs are mounted on the guide blocks; when the drill rod performs reciprocating knocking, the drill rod springs exert a drill rod resetting function; the hydraulic knocking mechanism is mounted inside the drill rod sleeve, and can knock the drill rod to achieve a breaking effect; the drill rod sleeve slides in the circular arc guide plates through drill rod sleeve sliding blocks; and the position of the drill rod sleeve is automatically adjusted through tracking springs, and the entire stretching length of the drill rod sleeve is changed along with the change of the breaking depth of a broken object. According to the small-amplitude tracking type breaking hammer, empty knocking phenomenon of the drill rod is prevented, the service life of the drill rod is prolonged, and the breaking hammer has a relatively good utilization effect.

Description

Technical field [0001] The invention belongs to the technical field of breaking hammers, in particular to a small-amplitude tracking breaking hammer. Background technique [0002] At present, the breaker has various drive modes such as hydraulic drive, nitrogen drive, nitrogen and hydraulic drive, gravity drive, etc. Each drive mode is achieved by hitting the drill rod at high speed so that the drill rod has a large kinetic energy in an instant to achieve crushing. The effect of the object; when the chisel is hit, the huge kinetic energy is released by breaking the object, but the chisel is often separated from the object during work, and the beating is still in progress at this time, and the huge beating kinetic energy cannot be released. Hitting will cause great damage to the drill rod, resulting in increased equipment operating costs. [0003] The present invention designs a small-amplitude tracking breaker to solve the above problems. Contents of the invention [000...
