Pipe pile mold bolts automatically follow the circular cycle tightening mechanism without power

Abstract

The invention relates to a pipe pile formwork bolt automatic follow ring cycle tightening mechanism without power. It is in a straight state and this section is formed as a straight working section; along the length direction of the flexible link, there are also a plurality of assembly and disassembly units that can be independently lifted; the length of the straight working section is greater than that of any two adjacent assembly and disassembly units. Linear spacing along the length of the flexible link. In the mechanism of the present invention, after the base frame body is fixed according to the design orientation, power can be obtained from the linear motion of the pipe pile mould, thereby driving the flexible chain link to follow the pipe pile The moulds follow the movement synchronously without power. During the rotation process, each assembly and disassembly unit completes the assembly and disassembly operations in an orderly manner in the straight working section. The pipe pile mold has no stagnation, and the assembly and disassembly units have no return travel, which can effectively improve production efficiency.

Description

Technical field [0001] The present invention belongs to the mechanical technical field of tightening or loosening screws or nuts in operation and transportation, specifically relates to a pipe pile mold bolt without power automatic following the ring circulation tightening mechanism. Background [0002] At present, the process of producing concrete pipe piles includes the following processes: wire drawing, cage weaving, concrete fabric, clamping, tensioning, centrifugal molding, steam protection and demoulding. Among them, the process of clamping and demoulding requires all the bolts on the pipe pile mold to be tightened and loosened. The pipe pile mold is linear in shape, which can be referred to in the annex Figure 1 , by the section is semicircular upper die and lower die buckled, the upper and lower die fastening surface along the diameter of the outward edge of the connection edge, through a number of bolts to the upper mold and the lower die connection edge and bolted. Howe...

Problems solved by technology

[0008] Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a pipe pile formwork bolt without power to automatically follow the circular cycle tightening mechanism, so as to avoid that the current automation equipment will limit the forward movement speed of the pipe formwork, resulting in low production efficiency. Higher problem, achieve a relatively simple structure and better practicability, and can better ensure the quality of pipe pile formwork screwing / removing bolts
