Abstract
The utility model relates to the technical field of a crane and hoisting equipment, in particular to a hand-shaken mechanism used for controlling a lifting appliance and a lifting hook to be lifted and descended. The hand-shaken mechanism comprises a shell body. A speed reducer is arranged in the shell body and comprises an input shaft, a driving wheel installed on the input shaft and a driven wheel meshed with the driving wheel and installed on an output shaft; a handle is arranged at one end, stretching out of the shell body, of the input shaft of the speed reducer; a self-locking mechanism is arranged on the input shaft of the speed reducer. The hand-shaken mechanism is suitable for the situation that when power failure of the lifting appliance occurs, the lifting motion of the lifting appliance and the lifting hook is achieved by operation staff in a hand-shaken manner.
Description
Technical field
The utility model relates to the technical field of crane and lifting appliance, especially a kind of for controlling the hand-operated mechanism of suspender hook lifting.
Background technology
Existing crane and weight-lifting equipment are in the lifting process, if having a power failure suddenly or the lifting appliance fault occurs, the equipment be lifted just can't put down again, has so great potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in the above-mentioned background technology, the utility model provides a kind of hand-operated mechanism, it for crane and weight-lifting equipment have a power failure suddenly or the situation broken down under, can manually control the dipping and heaving of suspender suspension hook.
The utility model solves the technical scheme that its technical matters adopts: a kind of hand-operated mechanism, there is housing, be provided with speed reduction gearing in housing, speed reduction gearing comprises input shaft, is installed on the driving wheel on input shaft and is meshed with driving wheel and is installed on the flower wheel on output shaft; The end that the input shaft of speed reduction gearing stretches out housing is provided with handle; Be provided with self-locking mechanism on the input shaft of speed reduction gearing.
Further limit, also be provided with the idle wheel be meshed with driving wheel in housing.
Further limit, driving wheel is between flower wheel and idle wheel.
The beneficial effects of the utility model: this hand-operated mechanism for crane and lifting appliance, when crane or lifting appliance have a power failure suddenly or break down, operating personal can manually be controlled the dipping and heaving of suspender suspension hook, simple to operate, safe.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure 1, housing, 2, input shaft, 3, driving wheel, 4, output shaft, 5, flower wheel, 6, handle, 7, self-locking mechanism, 8, idle wheel.
The specific embodiment
A kind of hand-operated mechanism as shown in Figure 1, have housing 1, in housing 1, is provided with speed reduction gearing, and speed reduction gearing comprises input shaft 2, is installed on the driving wheel 3 on input shaft 2 and is meshed with driving wheel 3 and is installed on the flower wheel 5 on output shaft 4; The end that the input shaft 2 of speed reduction gearing stretches out housing 1 is provided with handle 6; Be provided with self-locking mechanism 7 on the input shaft 2 of speed reduction gearing.
Also be provided with the idle wheel 8 be meshed with driving wheel 3 in its middle shell 1.Driving wheel 3 is between flower wheel 5 and idle wheel 8.
The concrete operation step of this hand-operated mechanism: do while clockwise rotating when Manual operation handle 6, can make suspension hook do upward movement, the weight on suspension hook is upwards promoted simultaneously; When stopping handle 6, rotate, due to the effect of self-locking mechanism 7 on input shaft 2, speed reduction gearing can not reverse, and therefore can not occur to cause because of the weight Action of Gravity Field situation that handle 6 reverses and weight glides; When Manual operation handle 6 is done left-hand revolution, can automatically open self-locking mechanism 7, make the weight slow decreasing; If stop handle 6, shake, due to the effect of self-locking mechanism 7, weight will be parked in current location.
