Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] refer to figure 1 , the structure of the device of the present invention is, comprises PLC controller 1, five electromagnetic valves ( figure 1 Y1, Y2, Y3, Y4 and Y5) are respectively controlled and connected. The five solenoid valves are all electronically controlled gas two-position reversing valves, and the input ends are respectively connected to the air source. Among them, the output end of the solenoid valve Y1 is connected to the locking cylinder. The air chamber of 4 is connected to output the lock release control air; the output end of the solenoid valve Y2 is connected to the rod cavity of the lock cylinder 4, and is used to output the lock control air; the output end of the solenoid valve Y3 is connected to the right side of the shift cylinder 3 The output end of the solenoid valve Y4 is connected with the middle chamber of...

The invention discloses a one-click gear shifting system of a drilling winch. The one-click gear shifting system comprises a PLC (Programmable Logic Controller), wherein the PLC is respectively in control connection with five electromagnetic valves in an electromagnetic valve island box, the five electromagnetic valves are electrically controlled air two-position reversing valves, the input ends of the five electromagnetic valves are respectively connected with an air source, and the output end of the electromagnetic valve Y1 is connected with an air cavity of a gear locking cylinder; the output end of the electromagnetic valve Y2 is connected with a rod cavity of the gear locking cylinder; the output end of the electromagnetic valve Y3 communicates with a right cavity of a gear shifting cylinder; the output end of the electromagnetic valve Y4 communicates with a middle cavity of the gear shifting cylinder; the output end of the electromagnetic valve Y5 communicates with a left cavity of the gear shifting cylinder; and the end of a piston rod of the gear locking cylinder is vertically hinged to a piston rod of the gear shifting cylinder, the piston rod of the gear shifting cylinder is fixedly connected with a gear shifting mechanism, and the gear shifting mechanism is arranged between a reduction gearbox and a drum shaft of a winch drum. The invention further discloses a one-click gear shifting method of the drilling winch, and the drilling efficiency and the automatic control level of the winch are increased.
Description
technical field [0001] The invention belongs to the technical field of petroleum machinery, and relates to a one-button gear shifting system of a drilling winch, and also relates to a one-button gear shifting method of a drilling winch. Background technique [0002] At present, the gear shifting of the oil drilling winch generally adopts manual shifting or operating cylinders for pneumatic shifting. Manual shifting is labor-intensive, difficult to operate, low in efficiency, and remote control cannot be realized; pneumatic shifting is generally completed by the air control valve and cylinder to control the shifting mechanism, but the success rate of shifting is low, and manual intervention by the operator is often required , and prone to failures, and even serious drilling accidents caused by false stalls. Contents of the invention [0003] The purpose of the present invention is to provide a one-button gear shifting system for drilling drawworks, which solves the problem...
