[0023] Furthermore, the machine room control cabinet 1 is bolted to the machine room floor 2. The machine room floor 2 is provided with a square groove. The machine room floor 2 is fixedly connected to the hoistway wall 3. The machine room control cabinet 1 is the power source, and the elevator car is powered by the current transmitted through the trailing cable 402. The trailing cable 402 enters the elevator hoistway through the square groove of the machine room floor 2. The hoistway wall 3 is used to fix the fixed part of the trailing cable 402.

[0024] Furthermore, the trailing cable 402 is electrically connected to the machine room control cabinet 1 through the machine room busbar terminal plug 401. The machine room floor 2 is fixedly connected to the machine room grooved shaft seat 403. The machine room grooved shaft seat 403 is rotatably connected to the drum 404. The width dimension of the trailing cable 402 matches that of the drum 404. The machine room busbar terminal plug 401 is installed at the top end of the trailing cable 402, which is convenient for the manual installation and disconnection operations of the trailing cable 402 and increases the service life of the trailing cable 402. The machine room grooved shaft seat 403 and the drum 404 bend the trailing cable 402 extending from the machine room control cabinet 1 downward, pass through the square groove of the machine room floor 2 and enter the elevator hoistway.

The side of the arc-shaped extended wire groove 407 coincides with the side of the elevator car. There are two groups of side protection plates 408. The trailing cable 402 extending vertically from the bottom cable clamp seat 406 is inserted into the arc-shaped extended wire groove 407. The extended part on the side of the arc-shaped extended wire groove 407 ensures that the moving part of the trailing cable 402 always remains in the idle space between the elevator car and the hoistway, preventing the trailing cable 402 from contacting other devices in the hoistway and improving the safety of elevator use. The side protection plate 408 ensures that the trailing cable 402 maintains a good vertical shape and prevents it from swaying to both sides and getting entangled and knotted.

[0027] Furthermore, the arc-shaped protruding wire groove 407 is fixedly connected to the car vertical wire groove 409, and the car vertical wire groove 409 is connected to the side cover 410 by a slot connection. The car vertical wire groove 409 is connected to the accompanying cable 402 by a slot through the side cover 410. The car vertical wire groove 409 matches the size of the side cover 410, and the inner groove of the car vertical wire groove 409 matches the size of the accompanying cable 402. The accompanying cable 402 passes through the arc-shaped protruding wire groove 407 on the car floor 7 and enters the car vertical wire groove 409 inside the side of the elevator car. The car vertical wire groove 409 connects the accompanying cable 402 at the bottom of the car to the car roof inspection box 6 at the top. The car vertical wire groove 409 inside the side of the elevator car reduces the redundant use area of ​​the cable, better provides protection for the accompanying cable 402, and prevents the accompanying cable 402 from being subjected to external physical damage. The side cover 410 facilitates the disassembly and installation of maintenance personnel, thereby reducing the maintenance time of the cable.

[0028] Furthermore, the wire trough plate 411 and the car top plate 5 are fixedly connected, the accompanying cable 402 is electrically connected to the car top inspection box 6 through the car top collection terminal plug 412, the car top plate 5 and the car top inspection box 6 are bolted, and the end of the accompanying cable 402 on the bridge top is installed with a car top collection terminal plug 412, which is convenient for manual installation and disconnection operations of the accompanying cable 402 and increases the service life of the accompanying cable 402. The car top inspection box 6 is connected through the accompanying cable 402 to provide power and connection control lines for the car top electrical equipment, thereby realizing the up and down control of the elevator by the machine room.

[0029] Working principle: First, the machine room control cabinet 1 on the machine room floor 2 is started. The machine room control cabinet 1 is the power source. At the top end of the trailing cable 402, there is a machine room busbar terminal plug 401, which facilitates the manual installation and disconnection operations of the trailing cable 402 and increases the service life of the trailing cable 402. The current is transmitted through the trailing cable 402 to supply power to the elevator car. The trailing cable 402 enters the elevator hoistway through the square groove of the machine room floor 2. The trailing cable 402 extending from the machine room control cabinet 1 enters the drum 404 in the center of the machine room grooved shaft seat 403 and bends downward, passes through the square groove of the machine room floor 2 and enters the elevator hoistway. At the same time, the placement position of the trailing cable 402 is fixed to prevent the trailing cable 402 from being wound and knotted, improving the straightness in the elevator hoistway and preventing the trailing cable 402 from swinging on the hoistway wall 3 and contacting other components. Use bolts to fixedly install the cable holders 406 on both sides of the trailing cable 402 extending downward in the machine room on the fixed wall seat 405. Repeat the above operations to complete the installation of several groups of cable holders 406 for the fixed part of the trailing cable 402. Then, the trailing cable 402 extending vertically from the bottom cable holder 406 is inserted into the arc-shaped protruding wire groove 407. The protruding part on the side of the arc-shaped protruding wire groove 407 ensures that the moving part of the trailing cable 402 always remains in the idle space between the elevator car and the hoistway, preventing the trailing cable 402 from contacting other devices in the hoistway and improving the safety of elevator use. The side protection plate 408 ensures that the trailing cable 402 maintains a good vertical shape and prevents it from swinging to both sides and getting wound and knotted. The trailing cable 402 passes through the arc-shaped protruding wire groove 407 on the car floor 7 and enters the car vertical wire groove 409 inside the side of the elevator car. The car vertical wire groove 409 slides the trailing cable 402 at the bottom of the car into the wire release groove and connects it to the top car top maintenance box 6. The car vertical wire groove 409 inside the side of the elevator car reduces the redundant use area of the cable and provides good protection for the trailing cable 402, preventing the trailing cable 402 from being physically damaged externally. The side cover plate 410 facilitates the disassembly and installation by maintenance personnel and reduces the cable maintenance time. Finally, the trailing cable 402 on the car top is connected to the car top maintenance box 6 through the car top busbar terminal plug 412 to provide power and connection control lines for the car top electrical equipment, realizing the up and down control of the elevator by the machine room. In this way, the use process of an elevator trailing cable protection device is completed.
