Abstract
The utility model relates to a manual lifting device, which is characterized by comprising a handle, a speed reducer and a coupler. The handle is connected onto an input shaft of the speed reducer, an output shaft of the speed reducer is connected with a winding drum shaft of a crane by the coupler, the coupler includes a first half coupler and a second half coupler, the first half coupler is axially mounted on the output shaft of the speed reducer in a sliding manner by the aid of a spline, and the second half coupler is fixed to the winding drum shaft. The crane with the structure can continue lifting a heavy object to a certain height after an electric hoist of the crane fails, so that the crane is applicable to places with special requirements on operation procedures.
Description
Technical field
The utility model belongs to weight-lifting equipment bont technical field, particularly relates to a kind of hand hoisting device of hoisting crane.
Background technology
At present, cucurbit formula hoisting crane is a kind of as weight-lifting equipment, because of have volume little, from heavy and light, characteristics such as simple to operate and easy to use, be widely used in places such as industrial and mining enterprises, storage harbour.In the lifting process of hoisting crane, if the hoisting crane et out of order, the weight that is taken up need put down on the spot, then hoisting crane is keeped in repair.But under some special environment for use, as power plant, ordnance factory, chemical plant etc. and operating process is had in the unit of specific (special) requirements, be not allow its weight of slinging is put down during the hoisting crane et out of order midway, also must continue weight is lifted by crane the height of appointment.Therefore, need exploitation a kind of behind the electric block malfunction and failure of hoisting crane, still weight can be lifted by crane the device of certain altitude.
Summary of the invention
The utility model provides a kind of simple in structure, hand hoisting device of being used for cucurbit formula hoisting crane for solving the technical matters that exists in the known technology, and this device can continue to lift by crane certain altitude with weight behind the drive motor malfunction and failure of hoisting crane.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of hand hoisting device, it is characterized in that: comprise handle, reductor and coupler, described handle is connected on the input shaft of reductor, the output shaft of described reductor connects by coupler with the drum shaft of hoisting crane, described coupler comprises first half a coupler and second half a coupler, described first half a coupler endwisely slips and is installed on the output shaft of reductor, described first half a coupler is connected by spline with the output shaft of reductor, and described second half a coupler and drum shaft are fixed.
The utility model can also adopt following technical scheme:
Described first half a coupler and the engagement of the second half a coupler tooth.
The top of the output shaft of described reductor is connected by bearing with second half a coupler.
Described reductor is a worm-gear speed reducer.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, the drum shaft that is hoisting crane connects handle by reductor, handle is installed on the input shaft of reductor, and the drum shaft of hoisting crane connects by coupler with the output shaft of described hoisting crane.Operating personal can be realized manual hoisting heavy with this by the reel of handle drives hoisting crane.First half a coupler of above-mentioned coupler endwisely slips and is installed on the output shaft of reductor, in the machine operation of hoisting crane just often, described first half a coupler by endwisely slip be installed in the hoist roller axle on second half a coupler separate, hoist roller is by motor-driven.The hoisting crane that said structure is installed still can continue weight to lift by crane certain altitude behind the electric block malfunction and failure of hoisting crane, make hoisting crane applicable to operating process is had in the place of specific (special) requirements.
Used reductor was a worm-gear speed reducer during this was novel, and this reductor has anti-phase auto-lock function, and during the manual operation handle, hoisting heavy can not make the handle counter-rotating operator that injures, and can protect the operator, eliminates hidden danger.
Described first half a coupler and second half a coupler adopt the tooth engagement, and two half a couplers engagements of this structure are stable, and stressed evenly, coupler to benefit from the life-span long.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, handle; 2, reductor; 2-1, input shaft; 2-2, output shaft; 3, first half a coupler; 4, second half a coupler; 5, drum shaft.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of hand hoisting device comprises handle 1, reductor 2 and coupler.Described handle 1 is a disc, and reductor 2 is a worm-gear speed reducer, and handle 1 is installed on the input shaft 2-1 of reductor 2 by flat key.The output shaft 2-2 of described reductor 2 is connected with the drum shaft 5 of hoisting crane by coupler.Above-mentioned coupler is made up of first half a coupler 3 and second half a coupler 4, and described first half a coupler 3 is installed on the output shaft 2-1 of reductor 2 by spline, and first half a coupler 3 can endwisely slip on the output shaft 2-2 of reductor 2; Described second half a coupler 4 is welded on the drum shaft 5 of hoisting crane, and is connected by bearing with the top of the output shaft 2-2 of reductor 2.The outer ring of described first half a coupler 3 is provided with the gear teeth, and the inner ring of described second half a coupler 4 is provided with the gear teeth, and first half a coupler 3 and second half a coupler 4 can pass through the tooth mesh transmission.During the hoisting crane normal operation, be that hoisting crane is driven by drive motor, first half a coupler 3 is by endwisely slipping on the output shaft 2-2 of reductor 2, realize that first half a coupler 3 separates with second half a coupler 4, this moment, this hand hoisting device was standby inactivity, and the normal operation of hoisting crane is not produced any influence.When hoisting crane in the lifting process, during the drive motor et out of order, the weight of being sling can be parked in the air, at this moment, manually first half a coupler 3 is endwisely slipped on the output shaft 2-2 of reductor 2 and with the engagement of second half a coupler, 4 teeth, operating personal rotary handle 1 can drive reel and lift by crane.This device can continue to lift by crane certain altitude with weight behind the drive motor malfunction and failure of hoisting crane.In the multiple place that operating process is had a specific (special) requirements.
