Homeostasis center supporting device

Abstract

The invention discloses a homeostatic center support device and belongs to the field of support machinery. The center support device comprises a fixed base, a hydraulic device and two rollers. The hydraulic device is connected with the fixed base through a hanging plate; the center support device also comprises an M-shaped support structure formed by sequentially hinging 4 support plates, meanwhile, the 4 support plates are respectively hinged with the fixed base, the two rollers and a piston rod of the hydraulic device; the hydraulic device is movably connected with the fixed base; and the piston rod of the hydraulic device can drive the support structure to move. The center support device can meet the requirements of the support machinery during the process of screw thread production of the tube product line, reasonably resolve the gravity and the unbalanced forces of the tubes and avoid the direct action of the irregular alternating stress on the hydraulic device as well as the damage of the unbalanced force to the hydraulic device resulted from the position deviation between the fixed base and the hydraulic device and prolong the service life of the hydraulic device.

Description

technical field [0001] The invention relates to a supporting machine in the pipe material processing process, in particular to a self-stable center supporting device. Background technique [0002] In the production and transmission process of oil and natural gas, a large number of pipes, such as various oil pipes or casings, etc. need to be applied. In order to facilitate connection, the ends of these pipes are generally turned with threads. Due to the long length and heavy weight of the pipe, during the threading of one end of the pipe, the middle or the other end of the pipe must be placed on a supporting device to ensure smooth operation of the pipe during turning. Existing support equipment is mostly implemented by hydraulic cylinders or cylinders directly pushing the rollers of the fixed support mechanism. The pipes to be processed are placed on the rollers of the support mechanism, and the lower part of the rollers is directly connected with the piston shaft of the hyd...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned support equipment has major defects: first, since the pipe to be processed is placed on the support equipment, the gravity of the pipe acts on the rollers of the support mechanism, and is finally transmitted to the hydraulic cylinder or cylinder piston directly connected to the rollers through the rollers. rod so that the hydraulic cylinder or air cylinder is fully loaded during the entire turning process

Under the direct action of the above two pressures, the sealing performance of hydraulic cylinders or cylinders will drop sharply, or even fail, which will cause greater safety hazards in the process of pipe turning, and serious accidents will easily occur; frequent replacement of hydraulic cylinders or cylinders increases The cost of pipe processing

In addition, the unbalanced force generated by the unavoidable relative position deviation between the fixed seat and the hydraulic equipment, and the fixed connection between the hydraulic equipment body and the fixed seat will cause the hydraulic equipment to be easily damaged by the unbalanced force and deformed or reduce its tightness
