A pipe pile upper mold and its hoisting system

Abstract

The invention discloses a pipe pile upper mold and its hoisting system, comprising a pipe pile upper mold main body and a hoisting device, the top of the upper mold body is provided with a T-shaped bracket, and the top of the T-shaped bracket is provided with a connecting groove. The middle part of one end of the T-shaped bracket is provided with a connecting bump; the present invention facilitates the connection and assembly of the upper die body, facilitates the fixing of the upper die body after assembly and connection, has strong stability, and facilitates the automatic addition of lubricating oil, which is convenient for bearing pressure, to prevent damage to the spreader, to facilitate the dehumidification of the main body of the upper die of the pipe pile, and to improve the service life of the main body of the upper die of the pipe pile, and finally to protect the spreader as a whole through the telescopic protective sleeve, which can effectively solve the traditional When the pipe pile mold is hoisted, it is easy to decouple or be subject to the production risk of swinging left and right caused by high-strength steel cables. At the same time, only one driving operator is required to automatically complete the hoisting and unloading of the pipe pile mold, 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
