Abstract

The utility model relates to an embedded electric hoisting mechanism of a crane, comprising a winding drum device, a speed reducer with a motor, a brake and a lifting hook set. The embedded electric hoisting mechanism of the crane is characterized in that support seats are arranged at the outer parts of two sides of the winding drum device, the brake connected with the speed reducer is arranged on the support seat at one side of the winding drum device, the speed reducer with the motor is arranged above one side at the inner part of the winding drum device, and is fixedly connected with the support seats outside the winding drum device, a gear on a low-speed shaft of the speed reducer with the motor is combined and meshed with an inner gear of the winding drum device. The embedded electric hoisting mechanism of the crane has the following advantages: the structure of the crane is more compact, the volume and the whole size of the crane are reduced, and under the condition of same lifting weight and same lifting height, the hoisting mechanism occupies small space, has light dead weight, and can meet the special requirement on narrow using space in industries such as nuclear power, military project and the like.

Description

The embedded electronic lifting mechanism of hoisting crane
Technical field
The utility model belongs to hoisting crane manufacturing technology field, particularly relates to a kind of embedded lifting mechanism of hoisting crane.
Background technology
At present, being applied to the crane hoisting mechanism in fields such as nuclear power and military project is made up of retarder, reel, drg and the steel rope etc. of translator, the retarder of described translator generally is installed in the reel outside, because retarder and reel take up space greatly, cause the also corresponding increase with manufacturing cost of oad of lifting mechanism.But because the particularity of industries such as nuclear power and military project, general hoisting crane is arranged in the cavern, when digging cavern in order to reduce construction cost, not only to dwindle usage space in the hole as far as possible, but also need the lifting mechanism volume and the overall dimensions of hoisting crane are dwindled as far as possible, crane hoisting mechanism of the prior art is so be subjected to the restriction of applying working condition.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, can dwindle crane hoisting mechanism volume and overall dimensions and save the embedded lifting mechanism of the hoisting crane of usage space.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: the embedded lifting mechanism of hoisting crane, comprise roll device, the retarder of translator, drg and suspension hook group, it is characterized in that: outside, described roll device both sides is equipped with supporting seat, wherein be equipped with on the supporting seat of a side and retarder bonded assembly drg, the retarder of described translator is arranged on the inner side of roll device, and captive joint the engagement that is harmonious of the gear on the retarder slow-speed shaft of described translator and the inner gear of roll device with the supporting seat in the roll device outside.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, make the structure of lifting mechanism more compact, and its volume and overall dimensions have been dwindled, under the hoisting capacity situation identical with lifting altitude, this lifting mechanism occupation space is little, from heavy and light, can satisfy the specific (special) requirements of the narrow and small usage spaces of industry such as nuclear power and military project; This kind structure lifting mechanism highly versatile can further extend other type hoisting crane product of exploitation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, drg; 2, supporting seat; 3, the retarder of translator; 4, roll device; 5, supporting seat; 6, retarder slow-speed shaft gear; 7, roll device inner gear; 8, connecting panel; 9, suspension hook group.
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 and Fig. 2, the embedded lifting mechanism of hoisting crane, the retarder 3, drg 1 and the suspension hook group 9 that comprise roll device 4, translator, described roll device 4 one side outsides are equipped with supporting seat 2, the opposite side outside is provided with 5, two supporting seats of supporting seat and fixes by connecting panel 8 and monkey frame or girder respectively.For ease of adjusting and maintenance, be equipped with on the supporting seat 2 of a side and retarder bonded assembly drg 1 therein.The retarder of described translator is arranged on the inner side of roll device, and captives joint with the supporting seat 2 in the roll device outside.The engagement that is harmonious of the retarder slow-speed shaft gear 6 of described translator and roll device inner gear 7.
During work, the motor-driven retarder high speed shaft of lifting mechanism rotates by retarder slow-speed shaft gear driven roll device; And rotate by motor positive and inverse, realize the hoisting of lifting mechanism, step-down operation.The purpose of carrying braking is hung in mainly playing of drg 1 on the supporting seat 2.
