DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] Example: Figure 1-Figure 5 The winch wire rope overwinding alarm control device shown in the figure includes a traction mechanism, the traction mechanism includes an iron box 11, the iron box 11 is fixedly placed on the ground, the device is installed as a whole at a position 20 meters away from the tail wheel of the dispatching winch, the traction mechanism includes a wire rope 10, the wire rope 10 is connected to the winch, a groove is provided at the upper end of the iron box 11, a base 2 is fixedly installed on the upper surface of the groove position of the iron box 11, a limited base 7 is fixedly installed on the base 2, the limited base 7 has the same area as the base 2, and a bearing seat 3 is fixedly installed on the limited base 7, and the bearing seat 3 is located at the center position of the upper surface of the limited base 7 A flap 5 is rotatably installed at the center of the bearing seat 3, and a groove is arranged at the upper end of the flap 5. The wire rope 10 shuttles between the grooves of the flap 5. The diameter of the wire rope 10 is smaller than the size of the groove of the flap 5. The end of the wire rope 10 away from the winch is connected with a wire rope triple ring 4. The size of the wire rope triple ring 4 is larger than the size of the groove of the flap 5. A limiter 6 is fixedly installed on the limit base 7. The limiter 6 is arranged at the lower side of the flap 5. After the flap 5 is flipped over, it contacts the upper end of the limiter 6. The lower end of the limiter 6 is connected with an alarm 23. The limiter 6 is electrically connected to the PLC, and the PLC is connected to control the winch motor. The winch wire rope overwinding alarm control device is installed at the dispatching winch 20 meters away from the rear connection port. When the winch pulls the wire rope 10, the wire rope 10 can normally shuttle back and forth in the groove of the flap 5, and the flap 5 can rotate and tilt on the bearing seat 3. The flap 5 maintains a vertical state in a natural state. When the wire rope 10 is pulled by the winch, the wire rope 10 pulls the wire rope triple ring 4. When the wire rope triple ring 4 is pulled through the flap 5, since the size of the wire rope triple ring 4 is larger than the groove of the flap 5, the movement of the wire rope triple ring 4 will support the flap 5 and drive the flap 5 to rotate, so that the flap 5 contacts the limiter 6. The limiter 6 drives the alarm 23 to alarm, and the limiter 6 sends a stop command to the PLC. Due to the inertia after the winch is stopped, the wire rope triple ring 4 will continue to move forward a distance of about one meter. By giving an alarm and controlling the winch to stop, the function of protecting the wire rope from overwinding is realized.

[0022] A lower sliding seat 13 is fixedly installed on the iron box 11, and the lower sliding seat 13 is installed at the notch position of the left end of the iron box 11. A movable wheel seat 14 is slidably installed on the lower sliding seat 13, and a wheel seat spring 15 is fixedly installed between the movable wheel seat 14 and the lower sliding seat 13. A control electric cylinder 16 is fixedly installed on the upper iron box 12, and a clamping wheel 17 is rotatably installed on the telescopic end of the control electric cylinder 16. A clamping wheel 17 is also rotatably installed on the movable wheel seat 14. The pull rope at the left end of the wire rope triple link 4 is between the two clamping wheels 17, and the control electric cylinder 16 is electrically connected to the limiter 6. When the flap 5 is flipped by the traction of the wire rope triple link 4, after the flap 5 contacts the limiter 6, the control electric cylinder 16 is started, and the control electric cylinder 16 drives the clamping wheel 17 to move downward, and the movable wheel seat 14 also moves downward, and the clamping wheel 17 drives the pull rope at the left end of the wire rope triple link 4 clamped between the clamping wheels 17 to bend, so that the wire rope triple link 4 is stretched in the opposite direction for a distance, compensating for the distance that the wire rope triple link 4 is pulled excessively.

[0023] Bolts 1 are installed on the base 2 and the bearing seat 3 , and the base 2 and the bearing seat 3 are fixedly connected by the bolts 1 .

[0024] A power line 8 is fixedly connected to the stopper 6 , and the stopper 6 is connected to a power source via the power line 8 .

[0025] A counterweight iron 9 is fixedly installed at the bottom of the flap 5, and the counterweight iron 9 allows the flap 5 to remain vertical when not in operation, and automatically reset after the traction of the wire rope 10.

[0026] An upper iron box 12 is fixedly mounted on the iron box 11, and a connection port 20 is fixedly arranged on the upper iron box 12. The steel wire rope 10 is connected to the winch through the connection port 20.

[0027] A dial 18 is fixedly mounted on the front end surface of the bearing seat 3, and a pointer 19 is fixedly mounted on the end surface of the flap 5. When the flap 5 rotates on the bearing seat 3, the pointer 19 is driven to rotate, and the pointer 19 rotates to different positions on the dial 18, indicating the distance that the wire rope 10 moves due to the inertia after the winch stops.

[0028] A limiter sliding block 21 is slidably mounted on the limiter 6, and a lower end protruding rod 22 is fixedly mounted on the lower end of the limiter sliding block 21, and the lower end protruding rod 22 is used to contact the alarm 23. When the flap 5 rotates to contact the limiter 6, the flap 5 presses the limiter sliding block 21 downward, and the limiter sliding block 21 drives the lower end protruding rod 22 to move, and the lower end protruding rod 22 moves to contact the alarm 23, and the alarm 23 is controlled to start the alarm.

[0029] The lower sliding seat 13 is fixedly mounted with a fixed wheel seat 24, and two groups of fixed wheel seats 24 are symmetrically arranged on both sides of the moving wheel seat 14. The moving wheel seat 14 can slide up and down on the lower sliding seat 13, while the fixed wheel seat 24 is fixed on the lower sliding seat 13, and a clamping wheel 17 is also rotatably mounted on the fixed wheel seat 24.
