A hydraulic fully automatic pile driver with a free lowering hoist to drive a heavy hammer

Abstract

The invention discloses a full-automatic hydraulic piling machine using a freely-lowering winch for driving a heavy hammer. The full-automatic hydraulic piling machine comprises a hydraulic control system and an electric circuit control system. The full-automatic hydraulic piling machine is provided with a pile lifting winch, the freely-lowering heavy hammer winch and automatic pile clamping mechanisms. The pile lifting winch and the freely-lowering heavy hammer winch are connected with a pile lifting control oil circuit and a heavy hammer control oil circuit respectively. The pile lifting control oil circuit and the heavy hammer control oil circuit are arranged in a hydraulic control system oil circuit in parallel. An automatic control rack hinge mechanism is arranged on the freely-lowering heavy hammer winch and connected with a PLC in the electric circuit control system. The automatic pile clamping mechanisms are arranged on a piling machine main arm, and a pile clamping system of the automatic pile clamping mechanisms is connected with the PLC. A diesel hammer is not needed for the automatic piling machine, a pile is automatically positioned, the piling process is fully automatic from beginning of the piling, operation is easy, labor is saved, efficiency is high, cost is low, and economic benefits are high.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a hydraulic full-automatic pile driver which drives a heavy hammer with a free-fall hoist. Background technique [0002] Existing pile drivers are powered by diesel hammers and oil cylinders. All pile driving equipment requires a hoist for hoisting piles and a hoist for hoisting hammers. [0003] Because the pile is pulled by the pile hoist in the pile hoist from a distance on the construction site and then lifted up, because the pile must stand under the heavy hammer, and the heavy hammer has a certain width and thickness. Some pile hoists cannot automatically stand the pile under the heavy hammer, because a wire rope can only lift the pile obliquely from one side of the heavy hammer. At this time, the wire rope is tied to the upper end of the pile, in order to make it stand upright. , it must be manually corrected by several people and placed on the designated p...

Problems solved by technology

[0008] The purpose of the present invention is to solve the problems in the prior art that the diesel hammer used for pile drivers is noisy, pollutes the environment, the hammer hoist is bulky, the positioning of piles needs manual operation, there are potential safety hazards, laborious operation, and low efficiency. No diesel hammer is required, the pile can be positioned automatically, the operation is simple and labor-saving, the piling process is fully automatic, the efficiency is high, the cost is low, and the economic benefit is a hydraulic automatic pile driver that drives the heavy hammer with a free lowering hoist
