Problems solved by technology

[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

Abstract

The invention belongs to the technical field of breaking hammers, and in particular relates to a small-amplitude tracking breaking hammer, which includes a drill rod, a drill rod sleeve, a hydraulic impact mechanism, a hydraulic control valve, a locking mechanism, and an arc guide plate, wherein the drill rod passes through the drill rod The sliding fit between the guide block and the sliding hole of the drill rod sleeve is installed inside the drill rod sleeve, and the drill rod spring is installed on the guide block, which plays the role of resetting the drill rod when the drill rod is reciprocatingly beating; the hydraulic impact mechanism is installed on the drill rod Inside the rod sleeve, the drill rod can be impacted to achieve the crushing effect; the drill rod sleeve slides in the arc guide plate through the drill rod sleeve slider, and the position of the drill rod sleeve is automatically adjusted by tracking the spring, so that the overall extension length of the drill rod sleeve can be adjusted accordingly. It varies with the crushing depth of the crushed object. The invention prevents the air strike phenomenon of the drill rod and improves the service life of the drill rod. It has good application effect.

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...
