[0002] Electric hoist is a special lifting equipment. It has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, warehouses, docks and other places. The electric hoist has a compact structure. The electric hoist with the motor axis perpendicular to the drum axis adopts a worm gear transmission device. Its disadvantages are: large length and width, bulky structure, low mechanical efficiency, and difficult processing. The hydraulic system is double-controlled, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. The electrical control department adopts low-voltage control to increase the safety of the control system. Electric hoists are usually used in enterprise production and cranes.

The lower surface of the adjusting frame 10 is fixedly connected to an electric hoist body 28.

[0031] In order to improve the buffering performance during braking, Figures 1 to 9As shown, the present application adopts the following structure. Through the arrangement of the driving gear 12, the damping spring 16, the brake hub 17 and the brake caliper 27, the electric hoist running sports car has the effect of improving the buffering performance when braking. In actual use, after the brake caliper 27 clamps the brake hub 17, the brake hub 17 produces braking performance, and when the brake hub 17 tends to stop rotating, the turntable 14 follows the brake hub 17 to stop rotating, and the engagement of the driving gear 12 with the rack 4 will cause the driving gear 12 to rotate when the running sports car moves. When tending to stop, the turntable 14 and the driving gear 12 have a differential speed, thereby causing the first arc groove 13 and the second arc groove 15 to be misaligned, applying pressure to both ends of the damping spring 16, causing the damping spring 16 to be compressed, thereby consuming energy through the damping spring 16 to achieve buffering. The effect is achieved by braking when the running sports car is about to stop, which can better protect the worm 20 and the worm wheel 18, and weaken the strong impact of the motor 19 caused by the immediate stop of the worm 20 and the worm wheel 18 after self-locking, that is, the damage to the worm 20 and the worm wheel 18 caused by the coordinated arrangement of the adjusting frame 10, the first connecting rod 23, the electric telescopic rod 24, the lifting block 25, the second connecting rod 26 and the brake caliper 27. During use, the upper ends of the two first connecting rods 23 can be driven to move toward the middle at the same time, thereby driving the two brake calipers 27 to hold the brake hub 17 to achieve the braking effect. When the brake hub 17 stops, it drives the turntable 14 to rotate, squeezes the damping spring 16, and consumes energy after the damping spring 16 is compressed, thereby achieving the purpose of facilitating the improvement of the buffering performance during braking.
