Abstract

The invention belongs to the technical field of walking type piling machinery hydraulic elements, and particularly relates to a dustproof hydraulic jacking device which comprises an inner sleeve and an outer sleeve connected outside the inner sleeve in a sliding mode, a cylinder body of a hydraulic cylinder is fixedly installed in the inner sleeve, and the upper end of a piston rod of the hydraulic cylinder is connected with a plurality of L-shaped connecting rods through pin shafts; the other end of the L-shaped connecting rod is connected to the outer sleeve through a pin shaft; the upper part of the outer sleeve is fixedly connected with a dust cover sleeving the L-shaped connecting rod; and the host working platform is fixedly connected to the outer sleeve. The inner sleeve, the outer sleeve and the dust cover are arranged outside the hydraulic cylinder to effectively seal the hydraulic cylinder, erosion of silt and mud to the hydraulic cylinder can be effectively prevented, and the service life of the hydraulic cylinder is prolonged.

Description

technical field [0001] The invention belongs to the technical field of hydraulic components of walking pile machinery, and in particular relates to a dust-proof hydraulic jacking device. Background technique [0002] The hoisting hydraulic cylinder is the basic equipment of the walking piling machinery, and its motion stability has an important influence on the dynamic performance of the walking piling machinery. The hoisting hydraulic cylinder is an important part of the walking piling machinery. Mechanical support for walking piles. Walking pile machinery is mainly used for building foundation construction (foundation forming, drilling and forming, pouring and backfilling, etc.), and its working environment is relatively harsh, and it is in contact with mud and sand. The hydraulic cylinder is worn and corroded, which in turn causes problems such as detachment of the surface coating on the piston rod (32) of the hoisting hydraulic cylinder, damage to the internal seal, sys...
