High-altitude self-discharging steel platepile lifting appliance

Abstract

The invention relates to a steel plate pile lifting conveying device, in particular to a high-altitude self-discharging steel plate pile lifting appliance. The high-altitude self-discharging steel plate pile lifting appliance comprises a lifting appliance body, a telescopic type lifting rod, a pulley assembly, a spring and a steel wire rope. The lifting appliance body comprises a clamp head and asleeve, the telescopic type lifting rod is mounted in the sleeve, the spring is arranged on the telescopic type lifting rod in a sleeving manner, the head of the telescopic type lifting rod extends out of the sleeve, and penetrates through a steel plate pile lifting hole and the clamp head, the pulley assembly is fixed to the lifting appliance body, the steel wire rope is mounted on the pulley assembly, one end of the steel wire rope is connected with the telescopic type lifting rod, the other end of the steel wire rope is drawn, the steel wire rope drives the telescopic type lifting rod to move, the head of the telescopic type lifting rod retracts into the sleeve, the steel wire rope is loosened, and the telescopic type lifting rod is reset under the effect of the spring. The lifting appliance can be dismounted in the high altitude, a crane can carry out other work immediately, construction efficiency is improved, and construction cost is reduced.

Description

technical field [0001] The invention relates to a steel sheet pile hoisting device, in particular to a high-altitude self-unloading steel sheet pile hanger. Background technique [0002] When the static pressure pile planting machine performs the pile foundation construction operation, the steel sheet pile needs to be hoisted at a high altitude. After the steel sheet pile is lifted by the spreader, it is fixed on the main fixture of the static pressure pile planting machine. At present, the commonly used hoisting method of steel sheet piles in my country is to use steel wire ropes to hoist through the openings on the upper part of the steel sheet piles. Since the hooks cannot be disassembled at high altitude, the hooks can only move with the pressing process of the steel sheet piles until they drop to At a certain height, workers can dismantle it on the ground, and then hoist the next steel sheet pile. This method is extremely wasteful of man-hours and completely restricts th...

Problems solved by technology

At present, the commonly used steel sheet pile hoisting method in my country is to use steel wire ropes to pass through the upper opening of the steel sheet pile. Since the hook cannot be disassembled at high altitude, the hook can only move along with the pressing process of the steel sheet pile until it drops to At a certain height, workers can disassemble the next steel sheet pile on the ground before hoisting the next steel sheet pile. This method wastes man-hours and completely limits the

[0003] Due to the above defects, if there are other working conditions on the site that require a crane, or the construction period is tight, it will affect the entire project, and it is not conducive to cost control
