In daily labor, a person can lift an object weighing about 100 kilograms with bare hands. Later people invented the explosion-proof chain hoist , which allows a person to lift 1 ton by pulling the chain Even heavier goods, many times more than manual work, so how can such a small hardware tool do it? We have been studying in depth what is the operating principle of explosion-proof chain hoists;
In fact, the operation principle of explosion-proof chain hoist is very simple: In the operation principle of explosion-proof chain hoist: It is manually pulled by a human hand, the manual chain drives the hand sprocket to rotate, and the manual fine chain is caught in the hand zipper wheel Therefore, the hand sprocket will rotate, and the rotation of the hand sprocket will cause the brake friction plate ratchet and the brake seat to press together and rotate together, so that the long tooth shaft will rotate the plate gear, the tooth short shaft and the spline hole gear.
In this way, the lifting sprocket mounted on the spline hole gear drives the lifting chain, thereby stably lifting the goods. It adopts a ratchet friction disc type single brake, which can brake by itself under load. The pawl engages with the ratchet under the action of a spring, and the brake works.
The main working principle of explosion-proof chain hoist is as follows:
Pull the hand chain (15), the hand sprocket (9) rotates, and press the friction plate (11), ratchet (14), and brake seat (10) into one body, driving the 5-tooth long shaft (5) to rotate, and the 5-tooth long shaft and The plate gear (8) is meshed, the plate gear is pressed into a four-tooth short shaft (7), the 4-tooth short shaft is meshed with the spline hole gear (6), and the spline hole gear and the lifting sprocket (4) are splined. The connection drives the lifting chain (1) to lift heavy objects.
The working principle of explosion-proof chain hoist is simply that it is relying on gears to turn into force, from small force to strong, one person can also lift one to two tons of goods, so when using explosion-proof chain hoist Pulling, oblique pulling, and other unqualified operations, to avoid the danger of the centripetal force being unstable due to the heavy object shaking when the oblique pulling is skewed, and the danger of heavy lifting falling off and falling may occur.
