Since the first fillet and the second fillet fit each other, when the reduction cylinder rotates, the reduction groove will be blocked by the reduction block, and then the shock absorber will shrink, so that the reduction cylinder can be decelerated. By opening the second electric cylinder so that the output shaft of the second electric cylinder squeezes the fixed plate, the fixed plate will compress the shock absorber, so that the reduction block moves out from the inner wall of the reduction groove, which can release the obstruction to the reduction cylinder and facilitate the deceleration and braking of the reduction cylinder.

[0060] See also Figure 3-Figure 6 In this embodiment, the central axis of the first cleaning roller 609 and the central axis of the through hole 706 are collinear, which is beneficial to the stable movement of the connecting block 703.

[0061] See also Figure 3 and Figure 4 In this embodiment, the first cleaning roller 609 is located below the second guide bar 705, and the first cleaning roller 609 is located above the first guide bar 704. After the wire rope passes through the wire groove on the first guide bar 704, it will be cleaned by the bristles on the side wall of the first cleaning roller 609.

[0062] Example 2: Please refer to Figure 7 On the basis of Example 1, the present application provides a technical solution: a deceleration brake assembly 8 for decelerating the drum 3 is provided on one side of the U-shaped seat 2, and the deceleration brake assembly 8 includes a fixed plate 801, a shock absorber 802, a fixed disk 803, a fixed column 804, a deceleration block 805, a U-shaped block 806 and a second electric cylinder 807; a fixed plate 801 is fixedly connected to the left and right edges of one side of the U-shaped seat 2, and two shock absorbers 802 are fixedly connected to the ends of the two fixed plates 801 close to each other, and the output end of the shock absorber 802 is close to the deceleration cylinder 13, A fixed column 804 is fixedly connected to the output end of the shock absorber 802, and a reduction block 805 is fixedly connected to the end of the fixed column 804 close to the reduction cylinder 13. The edge of the reduction block 805 close to the reduction cylinder 13 is provided with a first rounded corner, and the edge of the end of the reduction groove 14 away from the center of the reduction cylinder 13 is provided with a first rounded corner. The first rounded corner and the second rounded corner fit together. Since the first rounded corner and the second rounded corner fit together, when the reduction cylinder 13 rotates, the reduction groove 14 will be blocked by the reduction block 805, and then the shock absorber 802 will shrink, so that the reduction cylinder 13 can be decelerated.

[0063] See also Figure 1 and Figure 7 In this embodiment, four U-shaped blocks 806 are fixedly connected to one side of the U-shaped seat 2, each U-shaped block 806 corresponds to the shock absorber 802, and the upper and lower ends of the speed reduction block 805 are respectively fitted with the upper and lower ends of the inner wall of the U-shaped block 806. When the speed reduction block 805 is squeezed and moved by the speed reduction cylinder 13, it will move stably along the upper and lower ends of the inner wall of the U-shaped block 806.

[0064] Example 3: Please refer to Figure 7On the basis of Example 1, the present application provides a technical solution: the upper and lower ends of the U-shaped block 806 are fixedly connected with a second electric cylinder 807, and the output shaft of the second electric cylinder 807 is located in the area between the two fixed disks 803 at the same height. When in use, the second electric cylinder 807 is turned on so that the output shaft of the second electric cylinder 807 squeezes the fixed disk 803, and the fixed disk 803 compresses the shock absorber 802, so that the deceleration block 805 moves out from the inner wall of the deceleration groove 14, which can remove the obstruction to the deceleration cylinder 13.

[0065] See also Figure 1 and Figure 5 In this embodiment, a third electric cylinder 9 is fixedly connected to the upper part of one side of the U-shaped seat 2, and a clamping block 10 is fixedly connected to the lower end of the output shaft of the third electric cylinder 9. The clamping block 10 and the deceleration groove 14 are adapted to each other. When the third electric cylinder 9 is turned on and the clamping block 10 moves downward, the clamping block 10 enters the deceleration groove 14 to achieve the stationary state of the drum 3.

[0066] Working principle: When in use, the power take-off output is used to drive the direct-drive permanent magnet generator 15 to provide power for the winch. The power supply voltage range is AC330~500V. The frequency converter 18 drives the first servo motor 4, the first servo motor 4 drives the straight coaxial reducer 5, the straight coaxial reducer 5 drives the drum 3 of the winch, the electric control handle 22 or the manual control handle 23 controls the up and down stepless speed regulation of the winch, the handle neutral motor brake and the linkage mechanical brake, the manual torque control knob adjusts the system set torque in real time to ensure that the winch stops when encountering obstacles and the protection cable is not broken, the drive control system realizes constant torque and constant tension intelligent control of the winch, the parameter monitoring control display system monitors the winch operating parameters in real time, and the drum speed can be stably and accurately controlled in the range of 0.05~150r / min;

[0067] By using the electric control handle 22 to control the device, the electric drive control winch is more precise than the conventional hydraulic winch, and can also be compatible with grid power input, which is more environmentally friendly and has low operating costs;

[0068] In the automatic control mode, when you select lifting or lowering, the winch will run according to the program set on the human-machine interface, and monitor the speed, tension, depth, tension differential, air pressure, motor torque, motor temperature, bus voltage and current data during operation to see if they are normal. It will automatically brake or continue to run. All parameter warning values ​​can be set on the human-machine interface;

[0069] In the manual control mode, the manual control handle 23 is manually pushed to control the lifting or lowering direction and speed of the winch. The speed, tension, depth, tension differential, air pressure, motor torque, motor temperature, bus voltage and current data during operation will be displayed on the human-machine interface. If the parameter exceeds the parameter warning value, the device will issue an audible and visual alarm to remind the operator whether it is necessary to brake and stop;

[0070] Additionally, the control mode can be selected:

[0071] 1. Conventional control mode: The torque of the first servo motor 4 is set by the torque adjustment RP potentiometer. When lowering, it is set to the maximum, and the minimum is also set to more than twice the actual operating output torque to ensure that there is enough parking braking torque for lowering; when lifting, the torque is set to 1.5 times the actual output torque to ensure that the cable will not be broken when encountering obstacles. The direction can be controlled by the manual control handle 23 to control the rotation direction and speed of the first servo motor 4;

[0072] 2. Remote control jog control mode: remote control control, first press the remote control "power switch", when the remote control power indicator light is on, then press the remote control "START" start button. At this time, you can press "positive point" and "negative point" to control the jog direction. The jog running speed is set internally by the inverter 18. When the jog button is released, the first servo motor 4 maintains a zero-speed braking state, and the braking torque is the torque setting torque. The remote control potentiometer sets the torque during jog. After the emergency stop button is pressed, the remote control becomes invalid. After the emergency stop is released, you need to follow the steps again;

[0073] 3. Constant torque control mode: In the conventional control mode, the plugging operation mode, the first servo motor 4 is in the constant pure torque mode, the speed runs at the highest frequency, the output torque is given by the potentiometer, the torque is first adjusted to the minimum, and then the torque is gradually increased after the direction is given. The direction is given by the electric control handle 22, and the speed is not controlled. When the load torque is less than the set torque, the first servo motor 4 drags the load;

[0074] When the load torque is greater than the set torque, the first servo motor 4 follows the load; when the load torque is equal to the set torque, it remains stationary;

[0075] 4. When the system encounters an emergency, press the SBes emergency stop button, the system will decelerate to zero Hz at the fastest speed and lock the axis;

[0076] 5. When the system fails, the HU-type seat 2 fault indicator light will light up. After manually eliminating the fault, you can press the SBU-type seat 2 fault recovery button to reset the fault. After resetting, the HU-type seat 2 fault indicator light will go out.

[0077] Then, when in use, the wire rope can be passed through the first guide bar 704 and the second guide bar 705 and passed through the inside of the guide block 701 and installed on the side wall of the drum 3, and the wire rope will also be limited by the upper end of the wire roller 610;

[0078] Then, the second servo motor 605 is turned on to rotate the screw rod 606. The movement of the screw sleeve 607 drives the guide block 701 to move, and the slip ring 702 slides along the outer wall of the wire roller 610, so as to push the wire rope placed on the upper end of the wire roller 610, so that the wire rope can be wound on the drum 3 in an orderly manner.

[0079] At the same time, since the second servo motor 605 drives the screw rod 606 to rotate, the screw rod 606 drives the first synchronous pulley 611 to rotate, and the first synchronous pulley 611 drives the second synchronous pulley 612 to rotate through the synchronous belt body 613, which will drive the first cleaning roller 609 to rotate. The side wall of the first cleaning roller 609 is provided with bristles;

[0080] In actual use, the diameter of the through hole 706 is set according to the length of the bristles to ensure that the bristles can pass through the through hole 706. The bristles can brush and clean the wire rope in the wire groove on the first guide bar 704. The wire rope will also be brushed and cleaned by the second cleaning roller 707, the third cleaning roller 708 and the fourth cleaning roller 709, so that the side wall of the wire rope can be cleaned when the wire rope moves.

[0081] In addition, since the first fillet and the second fillet fit each other, when the reduction cylinder 13 rotates, the reduction groove 14 will be blocked by the reduction block 805, and then the shock absorber 802 will shrink, so that the reduction cylinder 13 can be decelerated. When the reduction block 805 is squeezed by the reduction cylinder 13 and moves, it will move stably along the upper and lower ends of the inner wall of the U-shaped block 806;

[0082] When it is not necessary to decelerate the reduction cylinder 13, the second electric cylinder 807 is turned on so that the output shaft of the second electric cylinder 807 squeezes the fixed plate 803, and the fixed plate 803 compresses the shock absorber 802, so that the deceleration block 805 moves out from the inner wall of the deceleration groove 14, thereby removing the obstruction to the reduction cylinder 13;

[0083] When the reduction cylinder 13 needs to be decelerated, the second electric cylinder 807 is turned on to retract its output shaft into the cylinder body. Finally, the third electric cylinder 9 is turned on to move the block 10 downward. The block 10 enters the deceleration groove 14 to achieve the stationary state of the drum 3.

[0084] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
