Product Introduction
This equipment is mainly used for disassembling and assembling various types of hydraulic cylinders, including columns and jacks of hydraulic supports. By adding accessories, it can also disassemble and assemble various hydraulic cylinders of construction machinery. It is widely applied to hydraulic cylinders with double - extension, single - rod extension, and threaded connection in fully mechanized mining supports, and is also suitable for oil cylinders where the cylinder barrel is connected with the guide sleeve via a clamping key.
It solves the problem that conventional horizontal disassembly and assembly of large hydraulic cylinders tends to cause thread damage due to the action of self - weight during disassembly and assembly. Each stage of the cylinder is disassembled and assembled in a vertical manner, and the torque of the guide sleeve can be adjusted flexibly. The application of this equipment greatly improves the assembly efficiency and quality of column oil cylinders, and reduces labor intensity.
The main unit of the equipment is made of steel plates through welding, followed by aging treatment and mechanical processing. It adopts a clamping method combining machinery and hydraulics to ensure reliable positioning and clamping of the column. For position avoidance, it can be tilted backward by 45°, facilitating the clamping of hydraulic cylinders; after being set vertical, it can realize the pressing - in of the piston rod. After clamping, a liftable oil cylinder is equipped at the base position of the column to adjust the effective distance between the threaded port of the column and the rotating part. The guide rail at the upper end of the frame adopts a high - strength body, which can bear large torque. The lifting oil cylinder is used to lift and lower the power sliding table, and the contact surface between the power sliding table and the frame is treated with wear - resistant materials.
The power part adopts a low - speed and high - torque hydraulic motor and a ratchet force - increasing mechanism, which are directly driven with the main shaft. The speed range of the hydraulic motor is adjustable, making it suitable for aligning and tightening the nuts of the cylinder head. The swing - type vertical structure has the advantages of convenient operation, easy thread insertion without being affected by gravity, small floor space, and safety and reliability.
