Problems solved by technology

[0004] The invention provides a pile pulling device, which aims to solve the problem that the existing pile pulling device on a ship uses a cable or a ferrule to be manually set on the outer surface of the round pile when the pile pulling device is pulling out the round pile. Large or located in the water, the staff is inconvenient or unable to go directly to the binding, resulting in delays in the construction period and other problems

Abstract

The invention discloses a pile pulling device, which comprises a chassis assembly, a traction assembly and a clamping assembly. The base, the internal gear is located inside the base, and the output shaft of the rotating motor is engaged with the internal gear; firstly, the traction motor drives the main gear to rotate, and the main gear passes through the transmission wheel Drive the pinion gear and the rope winding shaft to rewind or release the traction rope, and then adjust the position of the clamping assembly and lift and pull out the round pile. The power motor passes through the The gear set adjusts the angle between the main branch and the auxiliary branch, thereby adjusting the opening distance of the clamp ring on the left and right sides, and then clamping the round pile, reducing the overall work The risk factor in the process avoids the danger of the staff.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a pile pulling device. Background technique [0002] The mechanical method of pulling piles, that is, the electric motor drives the hoist, and the pulling force of the wire rope pulley block is used to force the piles out of the ground. It is easy to use and low in cost, but the pile pulling force is not large, the equipment is heavy, and the pile pulling efficiency is low. It is suitable for soft soil strata construction. [0003] In the extraction of circular piles, the existing pile pulling devices on ships use cables or ferrules to be placed on the outer surface of the circular piles manually. Because some piles are large in size or located in water, it is inconvenient for the staff or unable to directly Binding in the past caused delays in the construction period, etc. Contents of the invention [0004] The invention provides a pile pulling device, which ai...
