Strand winding apparatus of heavy caliber pipe winder

Abstract

The invention provides a winding displacement device of a winding machine for pipes with large diameter, which comprises a winding disk, a winding displacement screw mandrel, a winding displacement unit and a winding displacement motor, wherein, the winding displacement unit is arranged on the winding displacement screw mandrel; the winding displacement motor is connected with the winding displacement screw mandrel; the winding displacement unit winds the pipes on the winding disk; the winding displacement motor drives the winding displacement screw mandrel to propel so as to guarantee that the winding displacement unit winds the pipes on the proper position of the winding disk; and the winding displacement screw mandrel is connected with the winding displacement unit by threads and provided with a fixed thread pitch. By adopting the threaded connection, the invention leads the winding displacement unit to actively propel forward when the winding displacement screw mandrel rotates, thus overcoming the friction loss caused by the adoption of purely mechanical structure in the prior art, and can accurately control the rotating number of the winding displacement screw mandrel through the corresponding relation of the fixed thread pitch and the pipe diameter so as to realize the propelled distance needed by the winding displacement unit and lead the propulsion to be accurate, further, a sensing device can be used for realizing automatic feedback and control, thus leading the invention to be simple in structure, convenient and durable.

Description

technical field [0001] The invention belongs to pipe coiler equipment, in particular to a wire arrangement equipment for a large-caliber pipe coiler. technical background [0002] At present, the wiring of the coiling machine for large-diameter pipes adopts a purely mechanical structure. The sliding assembly of the cable arrangement relies on its own mechanical friction with the cable horizontal bar to generate reciprocating motion to realize the sequential arrangement of the pipes on the reel. [0003] The mechanical cable arrangement has the following disadvantages: [0004] 1. The wear caused by mechanical friction is large, the longer the time, the greater the wear and the lower the reliability. [0005] 2. The reciprocating motion of the cable is a "passive" movement, which is based on the premise that the pipes are arranged in sequence, and the pipe is pushed by the thrust of the outer wall of the pipe in the tangential direction; There are too many unstable factors...

AI Technical Summary

Problems solved by technology

[0004] 1. The wear caused by mechanical friction is large, the longer the time, the greater the wear and the lower the reliability

[0005] 2. The reciprocating motion of the cable is a "passive" movement, which is based on the premise that the pipes are arranged in sequence, and the pipe is pushed by the thrust of the outer wall of the pipe in the tangential direction; Rod movement, its unstable factors are too many

This utility model reduces the consumption of vulnerable parts to a certain extent and prolongs the service life of the machine, but its essence is still a "passive" movement, which inevitably produces large mechanical wear and cannot essentially overcome the existing technology. Defects
