Abstract
The utility model discloses a bidirectional hand chain hoist, belonging to portable or movable lifting or traction devices, in particular to a manual hoist crane, which comprises an upper hook, a lifting chain, a lifting hook, a deceleration transmission mechanism, a shell, a manual chain wheel, a manual chain, a brake and a manual chain wheel shaft, wherein one side of the manual chain wheel is equipped with a manual side shell, the reverse brake is symmetrically mounted with a former brake on the manual chain wheel shaft at two sides of the manual chain wheel and connected with the manual side shell, the brake and the reverse brake are equipped with mutually back locked clutches, and the clutches are connected with the manual side shell. The bidirectional hand chain hoist has simple structure, which can be modified based on existing hand chain hoist and produced by the existing equipment and fixtures by manufacturers of the existing hand chain hoist.
Description
Technical field
The utility model belongs to portable or mobile lift or draw gear, particularly manual hoist crane.
Background technology
Chain block is the manual weight-lifting equipment of using always, and it is by body.Bangle bar and hoisting chain are formed, and gear mechanism, brake equipment, hand chain wheel device and lift system that spur gear is formed are housed in the housing of body.When handing in hand chain, power drives the chain hoist wheel rotation by gear mechanism, load is risen or decline.Can only be with an end of chain but hoisting chain hangs when drawing weight, hang draw can not one-time-reach-place weight the time, need lifting chain is refunded, again sling, waste time and energy like this, draw the weight people not loose one's grip if hang with the other end, the weight of loosing one's grip can glide slightly, and may cause personal injury accidents.
The utility model content
The purpose of this utility model provides a kind of novel two-way chain block, and this two-way chain block can use the lifting chain two ends alternately to hang and draw weight.
The technical solution of the utility model is, a kind of two-way chain block, comprise hook, hoisting chain, lifting hook, reduction gearing mechanism, housing, hand chain wheel, manual chain, drg, hand chain wheel axle, it is characterized in that: the side at hand chain wheel is equipped with manual side body, the plugging device is installed in former drg symmetry and links to each other manually connecting on the wheel shaft and with manual side body of hand chain wheel both sides, on drg and the plugging device power-transfer clutch of locking mutually is housed, power-transfer clutch links to each other with manual side body.
The disclosed two-way chain block of the utility model is owing to increased the plugging device and the power-transfer clutch locked is mutually hanging when drawing weight, the manual chain of forward pulling hangs original drg work when drawing weight, after an end of lifting chain puts in place, oppositely the manual chain of pulling uses the other end of lifting chain to hang and draws weight, at this moment, the work of plugging device, circulation repeated use like this, the time and the manpower of unloaded jack have been saved, and guarantee all have the drg load can not occur retreating any time, improved the safety and the work efficiency of chain block.
The utility model is simple in structure, can reequip on original chain block, invests extremely lowly, and original chain block manufacturing enterprise can use the existing equipment frock to produce the utility model product.
