Five, the specific embodiment
A kind of stepless speed regulating well repairing device, as shown in Figure 2, form by operating room 1, console 2, hydraulic mechanism 3, base 4, motor shaft coupling 5, cylinder shaft coupling 6, wire rope 7, hydraulic tongs 8, overhead traveling crane 9, frame 10, cylinder 11, speed changer 12, motor 13, brake actuator 14, switch board 15, travelling block and hook 16, it is characterized in that base 4 is made as rectangle, be provided with the speed changer 12 on cylinder 11, motor 13 and both sides thereof in base middle part level; The base front middle part is fixed with frame 10, and the base rear portion is provided with hydraulic mechanism 3 and switch board 15; Be provided with operating room 1 and console 2 at base rear side middle part; The two end axles of cylinder links with cylinder shaft coupling 6 and speed changer 12 output shafts, motor reel links with the power shaft of motor shaft coupling 5 with speed changer, the other end of transmission input shaft and brake actuator 14 link, cylinder 11 is tied with wire rope 7, one end of wire rope is fixed on the cylinder, and the other end links with travelling block and hook 16 by the overhead traveling crane 9 at frame 10 tops; The fluid pressure line of hydraulic mechanism and hydraulic tongs 8 link; Power supply links with hydraulic mechanism 3 and switch board 15 respectively, and the control circuit of hydraulic mechanism and switch board links with console 2 respectively.The course of work that proposes oil pipe or beam hanger in the well is to serve to switch board and hydraulic mechanism, push away left operating grip forward, PLC gets signal brake release in the switch board, governing system starts, motor is just changeing drive speed transmission, the big more motor speed of the displacement that handle pushes away forward is high more, it is fast more that the speed changer head roll rotates the release wire rope, because the gravity of travelling block and hook and cylinder rotate the effect that discharges wire rope, wire rope moves travelling block and hook downwards by the crown sheave group, when hook during soon near oil pipe or beam hanger, left side operating grip reduces to the motor speed of pulling back, move original position to, PLC gets the signal motor stall in the switch board, and brake actuator brakes simultaneously; Push away right operating grip forward, PLC gets signal brake release in the switch board, governing system starts, the motor counter-rotating drives speed change gear, the big more motor speed of the displacement that handle pushes away forward is high more, it is fast more that wire rope is rolled in the rotation of speed changer head roll, make the upwards operation of travelling block and hook by the crown sheave group, when hook height can propose well head with whole oil pipe or beam hanger, right operating grip reduces to the motor speed of pulling back, move original position to, PLC gets the signal motor stall in the switch board, and brake actuator brakes simultaneously; Be clipped in oil pipe or beam hanger on the well head this moment, clamps oil pipe or the beam hanger that has proposed with hydraulic tongs, opens the positive turn-off of hydraulic tongs and close, and oil pipe or beam hanger rotate counterclockwise screw thread and unclamp, and closes the positive turn-off of hydraulic tongs and close, and hydraulic tongs is taken off on oil pipe or beam hanger.Repeat to push away forward left operating grip operation, hook operation downwards places on one side oil pipe or beam hanger, and repeating above operation can propose oil pipe or beam hanger successively in the artesian well.
The process of oil pipe or beam hanger is just mentioned oil pipe or beam hanger earlier under in well, then oil pipe or beam hanger are clipped in well head, hydraulic tongs is clamped oil pipe or beam hanger, open the hydraulic tongs reversal switch, oil pipe or beam hanger clockwise rotate screw thread and tighten, close the hydraulic tongs reversal switch, hydraulic tongs is taken off on oil pipe or beam hanger; Repeating above operation can be with oil pipe or beam hanger G.I.H successively.
Shown in Fig. 3 electric control theory block diagram, control principle is achieved in that
Pushing away left operating grip is forward just changeing enabling signal to PLC, and PLC output brake signal earlier gives control circuit, and control circuit control brake discharges; PLC output enabling signal and turn signal were given motor controller when brake discharged, and motor controller is exported on request and just transferred out power supply to motor, and be zero-speed this moment; Continue to push away forward the left operating grip fast given signal input motor controller of just walking around, motor controller is by the speed of just walking around of the fast given signal controlling motor of just walking around, sensor on the motor reel feeds back to motor controller with speed feedback signal, and the closed-loop control of the speed that realizes just walking around reaches the requirement of the fast given signal of just walking around; When motor needs stall, move left operating grip to initial position, PLC exports stop signal, the stall of motor controller control motor; Export brake signal simultaneously, control circuit is received brake signal, motor is braked the motor stall.
Operate right operating grip, push away right operating grip forward to the PLC enabling signal of reversing, PLC output brake signal earlier gives control circuit, and control circuit control brake discharges; PLC output enabling signal was given motor controller with the counter-rotating turn signal when brake discharged, and motor controller is exported the counter-rotating out-put supply on request and given motor, and be zero-speed this moment; Continue to push away forward right operating grip counter-rotating rotational speed setup signal input motor controller, motor controller is by the counter-rotating rotating speed of counter-rotating rotational speed setup signal controlling motor, sensor on the motor reel feeds back to motor controller with speed feedback signal, realizes that the closed-loop control of counter-rotating rotating speed reaches the requirement of counter-rotating rotational speed setup signal; When motor needs stall, move right operating grip to initial position, PLC exports stop signal, the stall of motor controller control motor; Export brake signal simultaneously, control circuit is received brake signal, motor is braked the motor stall.
