Embodiment Construction
[0019] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0020] Depend on Figure 1 to Figure 10 It is given that the present invention includes a horizontally placed I-shaped beam 1, two first gears 2 that can move left and right are respectively arranged in the grooves at the front and rear ends of the I-shaped beam 1, and the two gears 2 located on the same side of the I-shaped beam 1 The two first gears 2 are placed at intervals and are on the same level, and each first gear 2 is provided with a runner 3 concentric with the first gear 2 on the front and rear ends of each first gear 2, and the diameter of the runner 3 is larger than that of the first gear 2. Diameter, the runner 3 is connected to the first gear 2 via a shaft and can produce relative rotation, and each runner 3 is provided with a ring groove 4 on the end surface corresponding to the first gear 2, and a compr...

The invention relates to an electric hoist lifting buffering device. According to the electric hoist lifting buffering device, the problem that the service life of a cable is short duet to the fact that an existing electric hoist is short of buffering during lifting is effectively solved. According to the technical scheme, the electric hoist lifting buffering device comprises an I-shaped beam, twofirst gears which can move left and right are arranged in each groove of the front end and the rear end of the I-shaped beam, rotating wheels which are concentric with the first gears are arranged onthe front end face and the rear end face of each first gear, and an annular groove is formed in the end face, corresponding to the corresponding first gear, of each rotating wheel; each annular groove is internally provided with a compressed spring, and a second gear which can move up and down is arranged above the two first gears on the same side; a first tension spring is connected between thetwo rotating wheels which are located on the same side of each first gear, and extending shafts are arranged in the centers of the second gears; a fixing plate is arranged below the I-shaped beam, theextending end of each extending shaft is connected with the fixing plate through a second tension spring, and first telescopic rods are correspondingly arranged on the left side and the right side ofeach second tension spring; and a limiting device is arranged on the fixing plate. The electric hoist lifting buffering device is novel in conception and ingenious in structure.
Description
technical field [0001] The invention relates to the field of electric hoist machinery, in particular to an electric hoist lifting buffer device. Background technique [0002] Electric hoist is a tool that is often used in factories and construction sites. At present, my country has introduced and developed various types of electric hoist devices with different functions and powers from abroad. The foundation has been laid for rapid development. The electric hoist is a kind of hoisting equipment in which the motor drives the roller to decelerate through the reducer to realize the rotation of the roller to drive the weight to rise. The motor does not accelerate very much at the beginning, so that the speed of the roller is consistent with the speed of the motor after deceleration. Although the motor has been decelerated The motor decelerates but still has a high initial speed, so it is easy to break the cable hanging the heavy object at the moment of starting up. At present, t...
