Embodiment Construction
[0017] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] Depend on Figure 1 to Figure 9 Provided, the present invention includes a rotating shaft 1 placed horizontally, a plurality of first compression springs 2 are evenly distributed on the outer surface of the rotating shaft 1, and one end of each first compression spring 2 is fixedly connected to the outer surface of the rotating shaft 1. On the circular surface, the other end is connected with an arc-shaped plate 3, and a plurality of arc-shaped plates 3 form a hollow cylindrical structure concentric with the rotating shaft 1. The arc-shaped plate 3 can move along the meridian direction of the transmission shaft 1. The left and right ends of the plate 3 are provided with a first turntable 4 that is fitted and fixed on the rotating shaft 1, and the first turntable 4 is provided with a plurality of arc-shaped plates ...

The invention relates to a steel rope buffering device of an electric hoist, which aims to effectively solve the problem of short service life of cables due to insufficient buffer when an existing electric hoist is lifted. The steel rope buffering device adopts the technical scheme that the steel rope buffering device comprises a rotating shaft, wherein a plurality of first compression springs areuniformly distributed on the circumference of the rotating shaft, arc-shaped plates are connected to the other ends of the first compression springs, first rotary tables are respectively arranged onthe left and right ends of a plurality of arc-shaped plates, chutes are formed in the first rotary tables, a friction plate is arranged in each chute, a plurality of second compression springs are arranged on each friction plate, a friction lever is arranged on the outer side of each friction plate, second rotary tables are installed on the outer sides of the first rotary tables, annular grooves are formed in the second rotary tables, third compression springs are arranged in the annular grooves, the third compression springs are fixed to the first rotary tables by virtue of pin shafts, ropesare arranged on the second rotary tables, the other ends of the ropes are fixed to the friction levers, ratchets are arranged on the outer sides of the second rotary tables, and a pawl which is matched with each ratchet is arranged above each ratchet. The steel rope buffering device has the advantages of novel concept and clever structure.
Description
technical field [0001] The invention relates to the field of electric hoist machinery, in particular to an electric hoist steel rope 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 hoist 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...
