Adjustable hydraulic pile breaking machine of shovel claw

Abstract

The invention relates to an adjustable hydraulic pile breaking machine of a shovel claw, and belongs to the field of foundation construction. The adjustable hydraulic pile breaking machine is used forsolving the problems that in the foundation construction process, the effect of dismantling a pile body is not good, the efficiency is low, and the workload is large. The device adopts a central symmetry structure and comprises a lifting lug 1, an oil cylinder upper pin shaft 2, an oil cylinder 3, an oil cylinder lower pin shaft 4, shovel claws 5, a movable arm adjusting pin 6, a movable arm 7, amovable arm pin shaft 8 and a base 9, the lifting lug 1 is welded to the base 9, and an oil cylinder barrel is connected to the base 9 through the oil cylinder upper pin shaft 2; an oil cylinder piston rod is connected to the movable arm 7 through the oil cylinder lower pin shaft 4, the movable arm 7 is connected to the base 9 through the movable arm pin shaft 8, the shovel claws 5 are connectedto the movable arm 7 through the movable arm adjusting pin 6, and the four shovel claws point the center of the pile body. The machine and a crane are cooperatively used, an oil pipe of the crane is connected with the oil cylinder 3, and power is provided for the machine through the oil cylinder 3; the oil cylinder drives the movable arm 7 and the shovel claws 5 to extrude the pile body, parallelconnection of hydraulic pipelines achieves synchronous motion, the same section of the pile body is extruded synchronously in four directions, and the purpose of dismantling the pile body is achieved.

Description

technical field [0001] The invention relates to the field of foundation construction, in particular to a hydraulic pile breaker with adjustable shovel claws. Background technique [0002] Modern high-rise buildings, high-speed railway foundations, viaducts and other construction fields must carry out pile foundation operations. Whether it is the construction or removal of pile foundations, the pile heads need to be removed to a certain extent. At present, hydraulic breakers are used abroad for operations. An important purpose of breaking pile foundations is to recycle steel bars. If the manual operation is improper, it is likely to cause the steel bars to be scrapped and unusable. However, manual hammering is still used in China to break pile concrete. The labor intensity is high and the construction period is long, so it is very important to propose a device that efficiently solves such problems.
