The utility model discloses, through take turns the inside multiunit elastic component that sets up at the hoist to provide sufficient elasticity, be fit for large -scale building crane, prevent that it from appearing overloading, and lead to the tower crane rupture.
Description
Technical field
The utility model relates to technical field of buildings, is specially the anti-overload elevator of a kind of building crane and takes turns.
Background technology
At present, elevator wheel for building is mostly holistic elevator wheel, plays the effect in take-up and defence line in use procedure, in prior art, the construction type lift crane for anti-overload is a main shaft, by arranging elastic parts in main shaft inside, when there is overload condition, elastic parts inside contracts, and then the power that electrical motor is provided disconnects, but, this device acts on a main shaft, causes the elastic force of elastic parts limited, in large-scale lifting place, cannot use, have some limitations.
Summary of the invention
The purpose of this utility model is to provide the anti-overload elevator of a kind of building crane to take turns, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: the anti-overload elevator of a kind of building crane is taken turns, comprise elevator wheel housing, mobile jib, gear, hollow stem, half sphere shape, coil spring and bearing, the both sides of described elevator wheel housing are connected by described bearing with described mobile jib, one end of described mobile jib is provided with described gear, the inside that described mobile jib is being positioned at described elevator wheel housing is provided with described hollow stem, the top of described hollow stem is provided with described half sphere shape, is provided with described coil spring bottom described hollow stem and between described half sphere shape.
Preferably, the inside face of described elevator wheel housing is provided with and organizes hemispherical groove more.
Preferably, the radius of described hemispherical groove is identical with the radius of half sphere shape.
Preferably, described hollow stem comprises many groups, and is evenly arranged on the surface of described mobile jib.
Preferably, the radius of described mobile jib and the length sum of described hollow stem 0.1-0.2 millimeter larger than the radius of described elevator wheel housing.
Preferably, described hollow stem top is connected for active with the bottom of described half sphere shape.
Preferably, during installation, described mobile jib connects base by bearing.
Preferably, described coil spring is in compressive state.
Compared with prior art, the beneficial effects of the utility model are: the utility model organizes elastic parts by arranging in elevator wheel inside more, to provide enough elastic force, is applicable to large-scale building crane, prevents it from occurring overload, and cause tower crane to fracture.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, a kind of embodiment that the utility model provides: the anti-overload elevator of a kind of building crane is taken turns, comprise elevator wheel housing 1, mobile jib 2, gear 3, hollow stem 4, half sphere shape 5, coil spring 6 and bearing 7, the both sides of described elevator wheel housing 1 are connected by described bearing 7 with described mobile jib 2, one end of described mobile jib 2 is provided with described gear 3, the inside that described mobile jib 2 is being positioned at described elevator wheel housing 1 is provided with described hollow stem 4, the top of described hollow stem 4 is provided with described half sphere shape 5, described coil spring 6 is provided with bottom described hollow stem 4 and between described half sphere shape 5, the inside face of described elevator wheel housing 1 is provided with organizes hemispherical groove more, the radius of described hemispherical groove is identical with the radius of half sphere shape 5, described hollow stem 4 comprises many groups, and is evenly arranged on the surface of described mobile jib 2, the radius of described mobile jib 2 and the length sum of described hollow stem 4 0.1-0.2 millimeter larger than the radius of described elevator wheel housing 1, described hollow stem 4 top is connected for active with the bottom of described half sphere shape 5, during installation, described mobile jib 2 connects base by bearing 7, described coil spring 6 is in compressive state.
Concrete occupation mode: in utility model works, when there is overload condition, the elastic force provided due to coil spring 6 is not enough to keep out the rotation dynamics that elevator takes turns housing 1, and then half sphere shape 5 is extruded, enter in hollow stem 4, thus elevator wheel housing 1 is stopped doing power.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
