Problems solved by technology

In the actual operation process, since the effective stroke of the cylinder is only 0.5m, the extubation column needs to go through multiple cycles, and the double cylinder structure has disadvantages in terms of high-pressure liquid demand, stability control of the pulling process, and equipment weight control
[0005] To recover pillars in the mine stope, the torque of the hoist can be converted into the pulling force for pulling out the metal pipe by means of the hoist through components such as anchor rods and pulleys. Reduced recycling efficiency

Abstract

The invention relates to a hollow tube-drawing machine and designs the machine according to the hydraulic principle to solve the problems such that the existing tube-drawing equipment is heavy, short in stroke and low in recovery rate. The hollow tube-drawing machine mainly comprises a top disc 1, a small cover plate 2, a sealing gasket 3, an outer hoop 4, a tertiary cylinder block 4, a tertiary cylinder block base 14, a secondary cylinder block 6, a secondary cylinder block base 15, a primary cylinder block outer ring 7, a primary cylinder block inner ring 8, a jacket 9, a lining 10, a sealing ring 11, a primary cylinder block base 12, a cavity 13, a main base 17, an oil transfer channel 16, oil transfer holes 19, and a quick connector 18. The hollow tube-drawing machine is light and speedy, convenient to move and simple to operate, allows valuable tubular objects to be recovered efficiently, easily and safely, allows labor to be less intensive for workers and helps improve labor efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a multi-stage hollow pipe pulling machine, which is suitable for recovering pillars in mine stopes, recovering steel pipes wedged into the ground at civil and construction foundation sites, steel pipe guardrails in road traffic engineering, and temporary lifting Heavy objects etc. Background technique [0002] Metal pipes are used to maintain the safety of stope roof operation in the mining production process of mine access roads. A large number of metal pipes are used to isolate construction sites in foundation construction sites and traffic engineering, and a large number of metal pipes need to be recycled. [0003] In open-air construction sites, truck cranes are generally relied on to recover metal pipes, but temporary rental of truck cranes is time-consuming and labor-intensive, and the rent is high, so they cannot be on standby for a long time. On ...
