With the acceleration of urbanization, elevators are used more and more widely, and energy-saving technology has become an important development direction for the elevator industry.

[0003] During the operation of the elevator, especially when going up with a light load or going down with a heavy load, a large amount of regenerative energy will be generated. In the past, this energy was usually dissipated in the form of heat through braking resistors, resulting in energy waste. At the same time, the elevator will vibrate due to various factors such as friction during operation, which will cause noise during the operation of the elevator, affecting the passengers' riding experience.

[0038] The main frame assembly 1 includes an elevator shaft frame 101, a placement groove 102, a lifting rail 103, a through groove 104, a movable splint 105 and a reset spring 106. The placement groove 102 is symmetrically opened on the inner surface of the elevator shaft frame 101, the lifting rail 103 is fixedly connected to the inner surface of the elevator shaft frame 101, the lifting rail 103 is provided with a through groove 104, the movable splint 105 is slidably connected to the lifting rail 103, and the reset spring 106 is arranged between the movable splint 105 and the lifting rail 103, one end of the reset spring 106 is fixedly connected to the movable splint 105, and the other end of the reset spring 106 is fixedly connected to the lifting rail 103.

[0039] The driving rack 217 is meshedly connected to the rotating gear 301, the outer surface of the roller 216 abuts against the inner surface of the lifting rail 103, the car body 201 is slidably connected between the lifting rails 103, the driving pulley 207 and the driven pulley 208 are symmetrically arranged on the upper surface of the car body 201, and the driving pulley 207 and the driven pulley 208 form a meshing connection structure through the fixed teeth 209.

The electric energy inside the supercapacitor is used for restarting the elevator or lighting and ventilation equipment, so as to achieve the effect of recycling energy and saving electricity consumption.

[0042] When the elevator is operating normally, the car body 201 rises and falls normally inside the elevator shaft frame 101, and the rollers 216 arranged on the car body 201 roll as the car body 201 rises and falls, thereby reducing the friction force on the car body 201 during operation, thereby reducing the vibration generated by the operation of the car body 201.

[0043] When the car body 201 is operating normally, the driving rack 217 drives the rotating gear 301 to rotate at a normal speed. When the car body 201 fails and falls, the driving rack 217 drives the rotating gear 301 to rotate at a high speed. As the rotating gear 301 rotates at a high speed, the movable adjustment block 305 expands outward under the action of centrifugal force. At this time, the movable adjustment block 305 pushes the movable bracket 310 to move outward along the limiting slide groove 309. As the movable bracket 310 moves, the movable bracket 310 will move outward. The driving bevel gear 314 is displaced by the movable sleeve 313 until the driving bevel gear 314 is meshed with the driven bevel gear 315. After the driving bevel gear 314 is meshed with the driven bevel gear 315, the driven bevel gear 315 is driven to rotate. The driven bevel gear 315 rotates to drive the follower bevel gear 316 to rotate. The follower bevel gear 316 drives the driving pulley 317 to rotate.
