Problems solved by technology
[0004] The purpose of the present invention is to: design a novel hydraulic horizontal wire wrapping machine tailstock so that it can adapt to all small diameter PCCP pipes (DN≤2000mm), and can well adapt to the inclination of the end faces of PCCP pipes with different calibers. Solve the problem that the end face of the PCCP pipe socket is under local pressure due to constant jacking force, resulting in damage to the end face concrete

Embodiment Construction
[0011] In the actual production and use process, the PCCP pipe is transported by a crane or forklift to the height from the head of the horizontal wire winding machine to the center of the tailstock, the socket end of the PCCP pipe is placed on the socket connection plate of the wire winding machine head, and the motor is started (31), adjust the overflow valve (28) to set the system pressure according to the different pipe diameters, open the hydraulic cylinder push switch to make the hydraulic cylinder (1) push the sliding shaft box (9) to send the socket connection plate (23) to the PCCP pipe At the socket end, move the crane to align the socket of the PCCP pipe with the socket connection plate (23) of the tailstock system. After the socket part of the PCCP pipe enters the socket connection plate (23) of the tailstock and is in place, close the hydraulic cylinder push switch, and the hydraulic lock ( 33) Self-locking, loosen the hoisting wire rope, and perform wire winding o...

Abstract
The invention relates to a hydraulic tailstock of a horizontal type wire winding machine, which is capable of effectively solving the problems of narrow use range and low bearing capacity due to single jacking force of a horizontal type wire winding machine, capable of adapting to and adjusting inclination of end faces of PCCPs (prestressed concrete cylinder pipes) of various small pipe sizes, and capable of solving the problem of damage of concrete on the end faces of bell mouths and sockets of the PCCPs due to constant jacking force or local pressure, so that production efficiency of a whole production line is effectively improved, and production is greatly facilitated.
Description
technical field [0001] The invention relates to a horizontal wire wrapping machine (diameter DN≤2000mm) which fixes PCCP pipes during the process of winding prestressed steel wires, and prevents the PCCP pipes from sliding relative to each other due to the external force of the steel wires during the process of winding the prestressed steel wires. Background technique [0002] At present, horizontal wire winding machines are usually used when winding prestressed steel wires with small diameter PCCP pipes (DN≤2000mm). Put the socket end of the PCCP pipe on the socket connection plate of the winding machine head, and the tailstock drives the screw to rotate through the motor to slowly move the socket connection plate forward until it engages with the socket of the PCCP pipe, and the socket of the PCCP pipe After partially inserting into the connecting plate of the tailstock socket and in place, turn off the motor, loosen the hoisting wire rope, and perform the wire winding ope...
