Specifically, both the lowering shoe insulating rope 1 and the lifting shoe insulating rope 2 are flexible insulating ropes with certain bending properties, mechanical properties and electrical properties.

During the working process, when the train encounters an emergency and needs to cut off the power, pull the lowering shoe handle 13 to drive the lowering shoe insulating rope 1 to move upward, the lowering shoe compression spring 23 is compressed, and the lowering shoe insulating rope 1 moves in the lowering shoe tube 16. The force is transmitted to the support plate 11 and overcomes the force of the support plate spring 10. The support plate 11 rotates counterclockwise around the upper arm shaft 12. The support plate 11 and the upper arm 9 change from the gap state to the contact state. The support plate 11 continues to rotate counterclockwise. Rotation, the force of the support plate 11 is transmitted to the upper arm 9, overcoming the force of the main spring 4, the upper arm 9 rotates counterclockwise around the upper arm shaft 12, driving the slide plate 7 and the slide shaft 8 to separate from the power supply rail 6, realizing the disconnection When the power is turned on, the upper arm shaft 12 continues to rotate counterclockwise, and the slide shaft 8 enters behind the lock hook 5. At this time, the bushing 22 contacts the spring barrel 15, restricting the movement of the lowering shoe insulating rope 1. Between the lock hook 5 and the lock hook spring Under the action of 3, the skateboard shaft 8 is in the shoe lowering position. After the lowering shoe handle 13 is released, the support plate 11 is rotated clockwise under the force of the support plate spring 10, and the support plate 11 and the upper arm rod 9 are transformed from the contact state to the gap state, and return to the initial state. The shoe-lowering insulating rope 1 retracts under the force of the shoe-lowering compression spring 23, thus preventing the shoe-lowering handle 13 from swinging.

After the train fault is eliminated, or when the lifting shoe needs to be powered, pull the lifting shoe handle 14 to drive the lifting shoe insulating rope 2 to move upward, the lifting shoe compression spring 24 is compressed, and the lifting shoe insulating rope 2 moves in the lifting shoe tube 17. The force is transmitted to the lock hook 5 and overcomes the force of the lock hook spring 3. The lock hook 5 rotates clockwise, releasing the constraints on the skateboard shaft 8. The upper arm 9 drives the upper arm 9 smoothly under the force of the main spring 4. When the hour hand rotates, the slide plate 7 contacts the power supply rail 6 to close the main circuit. After the lifting shoe handle 14 is released, the lock hook 5 rotates counterclockwise under the action of the lock hook spring 3 and returns to the initial state. After the lifting shoe handle 14 is released, the lifting shoe insulating rope 2 retracts under the force of the lifting shoe compression spring 24, thus avoiding the swing of the lifting shoe handle 14.

During the operation of the train, when an abnormal situation is encountered, the main circuit needs to be cut off, and the force is manually transmitted through the insulating rope 1 of the lowering shoe to drive the slide plate 7 of the current receiver to separate from the power supply rail 6 to achieve power outage of the train. After the fault is eliminated, force is transmitted manually through the lifting shoe insulating rope 2 to drive the slide plate 7 of the current receiver to contact the power supply rail 6 to realize power supply for the train.

Because the insulating rope of the lifting shoe has flexibility and the ability to transmit force, it is convenient for the lifting device to be arranged in different positions, eliminating the restrictions on the installation space of the current receiver and the lifting device, making it convenient for the operator to operate and arrange equipment in the car, and improving the efficiency of the operator. safety.
