TSH type multi-rope friction hoist quick rope change machine
★THS type multi-rope friction hoist first rope quick replacement device is suitable for all kinds of floor type and tower type multi-rope friction hoist first rope replacement at the same time. Its step-type rope introduction device, the wire rope into the sky wheel and roller Jane, greatly improve the efficiency of rope replacement, reduce the labor intensity of workers, improve the safety of rope replacement process. The product has stepping fixed device and interlocking stepping moving device which can easily adjust the size of clamping force and control its open and closed loop condition, solving the problems of rope introduction, rope feeding, anti-winding, anti-labeling and tension unbalance; controlled anti-running device which can safely self-lock with double friction vice wedge; automatic control system which can monitor and control the whole process of fast rope changing device. The relevant experts identified, up to the international advanced level. Its main technical features are.
★Using the principle of "old rope with new rope", PLC online monitoring and real-time control, under the condition that the original winch is not involved in the operation of the loose gate, to achieve rapid and safe automatic replacement of multiple ropes at the same time.
★The use of double moving trolley (clamping mechanism) to achieve continuous step rope change process, rope change process of two moving trolley can achieve clamping and step sequence work.
★Anti-running rope device should adopt "wave pressure loose gate, spring holding gate" working mode, can realize the safety self-locking of the wire rope. In the process of rope change through the pressure transmitter on the anti-running rope device thrust cylinder pressure to achieve online detection, and has automatic replenishment pressure and pressure preservation function. Solve the fast catching when power failure or wire rope over speed movement, improve the safety and reliability.
★The speed of rope changing is realized online detection by speed sensor, and the equipment should have the function of over-speed automatic protection.
★ alternate step rope feeding device, anti-running rope device in contact with the wire rope are used in high efficiency friction village block, the new rope is not damaged.
★The process of sending rope can realize automatic control, also can realize manual control. Manual control and automatic control should be blocked, priority manual control.
★The preparation work before rope changing is mainly near the wellhead on the ground and does not affect the production.
★Rope changing process is fast, safe and less labor intensive.
Main performance and technical parameters.
★Applicable to replace the wire rope diameter: φ20- φ52.
★Adapted to replace the first rope spacing: 295- -305mm.
★stroke of stepping cylinder: 1m.
★Total tightening force of steel wire rope: ≥25t; Single rope clamping force: ≥5t.
★Rated working pressure: 16Mpa.
★The number of rope change at one time: 2-6 ropes.
★Average rope feeding speed:≥2m/min.
