CN215715663U - Hydraulic breaking hammer with sliding block - Google Patents

Abstract

The utility model relates to mining equipment, in particular to a hydraulic breaking hammer with a sliding block, which comprises a piston and a drill rod, wherein the piston does not directly strike the drill rod, the sliding block is arranged in an inner cavity of a front cylinder body between the piston and the drill rod, and the sliding block can only slide. Compared with the prior art, the sliding block slides in the upper cavity of the front cylinder body. The downward striking energy of the piston is transmitted to the drill rod through the sliding block. The sliding block can better absorb the radial component force transmitted by the drill rod, reduce the strain caused by the radial component force and reduce the failure rate of the breaking hammer.

Description

Hydraulic breaking hammer with sliding block

Technical Field

The utility model relates to mining equipment, in particular to a hydraulic breaking hammer with a sliding block.

Technical Field

The hydraulic pump is used as a power source, hydraulic oil is used as a medium, and the piston is driven to reciprocate by using the static pressure of the hydraulic oil as power, so that the piston impacts a drill rod at a high speed during the stroke, and the drill rod breaks solid such as ore, concrete and the like. However, the existing hydraulic breaking hammer still has some defects: the piston moves downwards to hit the drill rod, and the drill rod has larger radial separation in construction, so that the piston is easy to be damaged by pulling.

Disclosure of Invention

In order to overcome the technical defects in the prior art, the utility model discloses a hydraulic breaking hammer with a sliding block, which comprises a piston and a drill rod, wherein the piston does not directly strike the drill rod, the sliding block is arranged in an inner cavity of a front cylinder body between the piston and the drill rod, and the sliding block can only slide.

Further, the cross section of the sliding block is octagonal, and the cross section of the inner cavity of the front cylinder body at the matching position is also octagonal.

Compared with the prior art, the sliding block slides in the upper cavity of the front cylinder body. The downward striking energy of the piston is transmitted to the drill rod through the sliding block. The sliding block can better absorb the radial component force transmitted by the drill rod, reduce the strain caused by the radial component force and reduce the failure rate of the breaking hammer.
