Tubular pile upper die and lifting system

Abstract

The invention discloses a tubular pile upper die and lifting system. The tubular pile upper die and lifting system includes a tubular pile upper die and a lifting device, the top end of an upper die body is provided with a T-shaped support, the top end of the T-shaped support is provided with a connecting groove, and the center one end of the T-shaped support is provided with a connecting protruding block. The tubular pile upper die and lifting system is convenient for connecting and assembly of the upper die body, can conveniently fix the upper die body after connecting and assembly, and thestability is high; thereby facilitating automatic adding of lubrication oil, conveniently sharing pressure, preventing a lifting tool from being damaged, conveniently removing humidity for the tubularpipe upper die, and further conveniently prolonging the service life of the tubular pile upper die; through a telescopic protective sleeve at last, the entire lifting tool can be conveniently protected, thereby effectively solving the problems that a traditional tubular pile die is prone to disconnecting during lifting or taking risks generated by left-right swing of a high strength wire rope, the lifting and the unloading of the tubular die can be automatically completed by only one operation staff of a crane at the same time, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pipe piles, in particular to an upper mold for pipe piles and a hoisting system thereof. Background technique [0002] Pipe piles are divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and high-strength prestressed concrete pipe piles. Pile (PHC pipe pile). Pretensioned prestressed pipe pile is a hollow cylindrical slender concrete prefabricated component made by pretensioned prestressing process and centrifugal forming method. It is mainly composed of cylindrical pile body, end plate and steel ferrule. [0003] Pipe piles are divided into prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and prestressed high-strength concrete pipe piles (PHC pipe piles) according to the concrete strength grade an...

AI Technical Summary

Problems solved by technology

Everyone knows that pipe piles and molds are heavy, and are affected by inertia when driving. If the spreader fails to fit well with the pipe pile mold or the lifting hole on the pipe pile, it will fall off and cause accidental injury to the staff. The hook is connected to the crane through a high-strength steel cable. When moving, especially when the crane starts moving and stops moving, affected by inertia, the hoisted pipe pile or pipe pile mold shakes from side to side, which affects other equipment in the assembly line. At the same time, it will increase the risk of the hook falling off the pipe pile or the fishing hole of the pipe pile mold, and accidents will cause loss of life and property. At the same time, because the hook needs to be manually connected, the production efficiency of the pipe pile will be greatly reduced, and the increase in cost will not meet the requirements. The large-scale and assembly line production needs of modern enterprises
