Problems solved by technology

This pressure method is more reasonable, and the volume of the pile driver is also small, but if the holding pressure is not properly controlled, the holding pressure friction block will easily slip on the pile, so that the pile cannot be hugged and pressed into the ground, and then Affect the normal use of the static pile driver

Abstract

The holding and pressurizing device for static pressure pile machine includes frame on the pedestal of the pile machine, lower sliding box, one pair of swinging parts hinge to two sides of the sliding box, telescopic rod with lower end hinged to the swinging part connecting point and upper part connected to the driving device on the frame, holding and pressurizing friction block hinged to the swinging part connecting point, and locating friction blocks set via locating driving device to the inside of the sliding box. The present invention has the advantages of integrated holding and pressurizing operation, high work efficiency and capacity of correcting and locating the pile automatically.

Description

technical field [0001] The invention relates to a static pressure type pile driver for driving piles underground, in particular to a holding pressure device of the static pressure type pile driver. Background technique [0002] The structure of the traditional static pressure pile machine mainly includes: a frame set on the base of the pile machine, the base is provided with a longitudinal and horizontal driving mechanism, and the frame is equipped with a holding pressure device, and the structure of the holding pressure device mostly adopts pile holding The form separated from the pile pressing, that is, when the static pile machine is used, the pile must first be embraced by the pile holding mechanism, and then the pile will be pressed into the ground by the pile pressing mechanism. Because the process of holding the pile and pressing the pile is separated when this holding pressure device is used, its work efficiency is low, and the structure of this holding pressure devi...
