Problems solved by technology

At present, the lifting type pile extraction equipment basically pulls the pile upwards by clamping the pile head at 2 points. The opening and closing degree of the clamping device is small. When clamping the pile head, the operator needs to have certain operating experience and the clamping position is relatively accurate to be effective. Pile extraction, and the 2-point clamping is easy to damage the pile head or disengage the clamp during the pulling process, and the pile with a damaged pile head cannot be clamped, so that the pile cannot be pulled out

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] refer to Figure 1 to Figure 9 As shown, the hydraulic pliers type pile extractor in an embodiment provided by the present invention includes a hydraulic pliers type clamping device and a vibrating machine 7, the vibrating machine 7 is fixed on the hydraulic pliers type clamping device, and the vibrating machine 7 is provided with There are lugs 8 or hooks 9, wherein,

[0037] The hydraulic pliers clamping device includes an inner movable fixture 5 and an outer fixture 4. The inner movable fixture 5 includes a plurality of movable blocks distributed along the circumferential direction to form a clamp ring. The cross-sectional size of the inner ring of the clamp ring is the same as The cross-sectional dimensions of the piles are consistent; the outer fixture 4 includes two clamp arms, one end of the two clamp arms is connected by bolts, and the...

Abstract

The invention discloses a hydraulic tong type pile pulling machine and a pile pulling method. The hydraulic tong type pile pulling machine comprises a hydraulic tong type clamping device and a vibration machine. The vibration machine is arranged on the hydraulic tong type clamping device and provided with lifting lugs. The hydraulic tong type clamping device comprises an inner movable clamp and an outer clamp. The inner movable clamp comprises multiple movable blocks, and the multiple movable blocks form a clamp ring. The outer clamp comprises two tong arms. One end of one of the tong arms is connected with one end of the other tong arm through bolts, and electric hydraulic jacks are connected between the other ends of the tong arms. The outer clamp is arranged on the outer circle of the inner movable clamp in a sleeving manner, and the inner movable clamp is arranged on the outer circle of a to-be-pulled pile in a sleeving manner. The outer clamp locks the inner movable clamp through the electric hydraulic jacks, so that the inner movable clamp is closely attached to the to-be-pulled pile for clamping. The hydraulic tong type pile pulling machine is simple in sleeving assembly, large in clamping force, safe and reliable and attached to the pile more; the slipping-off situation generated in the pile pulling process is avoided; the pile can be pulled out more easily; efficiency is improved; a pile body is prevented from being damaged; and the hydraulic tong type pile pulling machine is simple in structure, easy to operate, small in size and free of limitation of geographic positions and facilitates construction.

Description

technical field [0001] The invention relates to the technical field of building construction machinery, in particular to a hydraulic pliers-type pile extractor and a pile extractor method. Background technique [0002] During the building construction process, it is necessary to pull out the temporary piles that need to be set up in the construction plane for the scheme measures, pull out the temporary piles set up in the lakes and rivers for environmental protection and use land resources in the process of urbanization, pull out the demolished old piles Concrete piles in soil after construction. Existing pile pulling equipment is mainly divided into two types of lifting type and ground holding pile pulling. Ground force-extracting piles need to be shifted by means of a crane because the pile-extracting equipment needs to be displaced. When pulling the piles, the piles are pulled out upwards by hydraulic jacks. When pulling the piles, a crane is required to straighten the p...
