Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides, for example Figure 1-4 The traction-driven passenger elevator shown includes a fixed frame 3 and an elevator body 5 installed inside the fixed frame 3.
[0026] A drive motor 7 is installed between the inner walls of the left and right ends of the fixed frame 3;
[0027] A drive rope 10 is installed between the drive motor 7 and the elevator body 5;
[0028] The other end of the drive rope 10 is provided with a counterweight 9. The lower outer wall of the drive motor 7 is fixedly connected to an emergency stop device 8. The emergency stop device 8 includes a gripper 14, a camera 15, and a driver 16. The camera 15 is provided on the lower side of the drive motor 7 to capture the sliding speed of the drive rope 10. The driver 16 is provided on the left side of the camera 15. One end of the driver 16 is fixedly connected to the gripper 14. The drive motor 7 pulls the elevator body 5 up and down through the drive rope 10. The counterweight 9 balances the load. If the speed of the elevator body 5 is unbalanced, the camera 15 will capture the motion image of the drive rope 10 and analyze it. When overspeed is calculated, the driver 16 is controlled to activate the gripper 14 to clamp the drive rope 10, thereby forcing the elevator body 5 to stop moving.
[0029] An opening 22 is provided inside the upper outer wall of the elevator body 5. A ventilation mesh 18 is installed inside the opening 22 to assist air circulation. When the elevator stops running due to a malfunction, passengers inside the elevator body 5 can use the opening 22 and the ventilation mesh 18 for auxiliary ventilation, which improves the air quality in the car and enhances passenger comfort.
[0030] like Figure 4As shown, a protective net 17 is fixedly connected to the upper outer wall of the elevator body 5, a connecting shaft 19 is fixedly connected to the left inner wall of the opening 22, a warning sign 20 is fixedly connected to one end of the connecting shaft 19, and a handle 21 is fixedly connected to the lower outer wall of the warning sign 20 near the right side, so as to control the opening and closing of the warning sign 20 under the action of external force.
[0031] The protective net 17 is inclined, which can prevent dust and impurities from being guided to the left and right sides of the ventilation net 18, thus avoiding the blockage of the protective net 17 and the ventilation net 18 by dust and impurities, which would lead to poor air circulation. When the elevator body 5 stops running, passengers inside the elevator can pull down the warning sign 20 by grabbing the handle 21 to flip it down, thus exposing the opening 22 for ventilation. The connecting shaft 19 is equipped with a ratchet assembly, which can limit the angle of the warning sign 20 each time it flips, ensuring that the warning sign 20 can cover the opening 22 when it is not pulled down.
[0032] like Figure 2 As shown, the emergency stop device 8 also includes a work box 13 to limit the position of the gripper 14, camera 15 and actuator 16.
[0033] The work box 13 is used to limit the position of the gripper 14, the camera 15 and the driver 16, and to provide power to the camera 15 and the driver 16. When the camera 15 detects that the drive rope 10 is falling rapidly, it transmits a signal to the driver 16, and the driver 16 controls the gripper 14 to move and clamp the drive rope 10.
[0034] like Figure 1 As shown, auxiliary wheels 2 are provided on the upper inner wall of the bottom frame 1 and the right side of the drive motor 7 to work with the drive rope 10 to keep the elevator body 5 stable during operation. An auxiliary rope 6 is provided between the two auxiliary wheels 2.
[0035] The auxiliary rope 6 may be located to the right of the drive rope 10, serving as a guide device. During the lifting and lowering process, the elevator body 5 may make slight contact with the auxiliary rope 6 to prevent it from swaying left and right.
[0036] like Figure 1 As shown, a base 11 is fixedly connected to the lower outer wall of the elevator body 5, a buffer 12 is fixedly connected to the upper inner wall of the bottom frame 1, and speed reducers 4 are provided on the inner walls of both the left and right ends of the fixed frame 3 to reduce the speed of the elevator body 5 when it moves.
[0037] The buffer 12 is a safety device used to absorb the kinetic energy of the elevator in the event of an unexpected descent, preventing the elevator from directly impacting the bottom or top of the shaft and thus protecting passenger safety. When the elevator impacts the buffer 12, the piston rod is pushed into the cylinder, forcing hydraulic oil through a small orifice. The resistance of the hydraulic oil flow generates a strong damping force, absorbing the kinetic energy of the elevator, slowing it down, and eventually stopping it. The reducer 4 is a mechanical device used to reduce the speed of the elevator body 5 when approaching the top or bottom of a floor, achieving a smooth stop and improving passenger comfort. The reducer 4 is equipped with multiple rollers to make contact with the elevator body 5 when approaching the floor, increasing the sliding resistance of the elevator body 5.
[0038] The implementation principle of this embodiment is as follows: the drive motor 7 pulls the elevator body 5 up and down through the drive rope 10, and the counterweight 9 balances the load. If the speed of the elevator body 5 is unbalanced, the camera 15 will capture the motion image of the drive rope 10 and analyze it. When overspeed is calculated, the driver 16 is controlled to activate the gripper 14 to clamp the drive rope 10, thereby forcing the elevator body 5 to stop moving. When the elevator stops running due to a malfunction, passengers inside the elevator body 5 can use the opening 22 and the ventilation net 18 for auxiliary ventilation to improve the air quality in the car and enhance passenger comfort.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
