Reinforced concrete pile crusher

Abstract

The invention discloses a reinforced concrete pile crusher, and mainly relates to the field of building machinery. The reinforced concrete pile crusher comprises a plurality of crushing devices, wherein each crushing device comprises a top steel plate, a bottom steel plate, a device housing welded between the top steel plate and the bottom steel plate, a servo hydraulic cylinder, a slide motor base and a servo motor; the crushing devices are fixed with one another end to end; a device cavity is arranged on the inner part of the device housing; the slide motor bases are in horizontal sliding connection in the device cavity; the output shafts of the servo motors are connected with power rotary shafts; the tail ends of the power rotary shafts get out of the device housing, and are equipped with drill bits; and each crushing device is fixedly arranged at the top end of a big arm of an excavator through a chain, and the corresponding servo hydraulic cylinder works through a hydraulic systemon an excavator. The reinforced concrete pile crusher has the beneficial effects that a reinforced concrete pile can be effectively cut off and cut up, so that reinforcement can be separated from a concrete pile to the greatest extent for recycling the reinforcement.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a reinforced concrete pile breaker. Background technique [0002] In the prior art, usually we manually cooperate with small machines or use a crushing vibrating hammer to clean up the concrete at the pile head, which has many potential safety hazards and high construction costs. In order to achieve the goal of liberating heavy physical labor and replacing dangerous working parts with machinery, while reducing construction costs and improving construction efficiency, on the basis of summarizing previous construction operations, the patent number is: 201410535771.0 Chinese invention patent: reinforced concrete In the pile head shearing and crushing device, it replaces the conventional work of manually cooperating with small machines or using a crushing vibrating hammer to clean the pile head concrete. Replaced by machinery, it becomes safe, labor-saving, time-saving, and lar...

[0003] But this invention patent is only applicable to concrete piles, not to reinforced concrete piles

After the concrete of the reinforced concrete pile is broken, the steel bars will be erected and exposed. Due to the setting of the "supporting working disc" in this invention patent, after the top layer of the reinforced concrete pile is broken, the top of the exposed steel bars will be in contact with the bottom surface of the "supporting working disc" , the erected exposed steel bars will block the "supporting work disc", so that the device cannot further break the reinforced concrete piles in the middle or bottom layer

[0004] Moreover, for reinforced concrete piles, if it is ensured that the steel bars can be separated from the concrete piles to the greatest extent and then the steel bars can be recycled, the concrete must be crushed to the greatest extent; this invention can easily cut off the concrete piles without reinforcement, but for those with high strength For reinforced concrete piles, the concrete pile at the center of the reinforced concrete pile cannot achieve the purpose of cutting and chopping, so that the steel bar and the concrete pile cannot be separated and the steel bar can be recycled.
