Abstract
The utility model discloses an electric crane with seven supporting legs and belongs to the technical filed of hoisting cranes. The electric crane with the seven supporting legs is characterized in that two front supporting legs are installed at the front portion of an auxiliary crane frame, two middle supporting legs are installed in the middle of the auxiliary crane frame, two rear supporting legs are installed at the rear portion of the auxiliary crane frame, and a tail supporting leg is installed at the middle part of the tail portion of the auxiliary crane frame. The electric crane is mainly used for complicated engineering sites and hoisting of heavy objects, and can be widely applied to installation of lines of telecom, electric power, wired televisions, post and telecommunications and the like and meet various construction requirements. Compared with a traditional crane, turning-over possibility of the crane is greatly reduced in the implementing process, stability in the hoisting process is improved, insurance for safety is increased, and the electric crane with seven supporting legs can be widely popularized and implementing.
Description
Technical field
The utility model relates to the lifting crane field, especially relates to a kind of seven supporting leg electric hoists.
Background technology
At present, the crane supporting leg has played requisite effect when crane is worked, and when crane was worked, supporting leg was used for dispersive pressure; Reduce pressure, also will fill up big sleeper below the general supporting leg, strengthen and ground-surface area of contact, if reduce pressure. hoisting crane is not easy to blow out when carrying weight like this; Or squish ground, when the lifting thing is heavier, can produce bigger downward pressure to car load; Four traditional supporting leg cranes do not suit in such working environment, to work, and car load disperses pressure to four supporting legs again, thereby can produce certain destructive force to ground; And can make car load in use stable inadequately, this has in use not only brought some negative influences to engineering, but also influences the service life of crane; Cause some unnecessary loss and trouble, because the daily lifting biochron, because weight is heavier; Can cause certain pressure to chassis cross-member, the crossbeam that bends probably causes the crane cisco unity malfunction, so two middle supporting legs are installed on crane; When hoisting heavy is heavier, owing to pressure can be partial to the lifting object space to cause lifting by crane object space to pressure excessive so that the lifting object space is directed at dangerous generation to sinking, car load is turned over; So added a tail supporting leg at the tailstock, though the lifting object space to supporting leg sink, the tail supporting leg also can form a bearing surface with other supporting legs; Needn't produce the danger of overturning and make to put in order, the crane of tail supporting leg has been installed, the overturning rate has reduced by 80% than the crane that is not equipped with the tail supporting leg.
The utility model content
For overcoming the problems referred to above, the utility model provides a kind of seven supporting leg electric hoists, and the technical scheme of employing is following:
A kind of seven supporting leg electric hoists comprise subframe, and subframe is provided with turntable; To preceding master winch, radiator, switch box, control cabin and the arm of being equipped with successively main suspension hook is installed on the arm by back on the turntable, big arm oil cylinder is connected with arm through hinge with the feeler lever oil cylinder; The master winch below is equipped with main oil tank, and main oil tank one side is equipped with main oil pump, and subframe is provided with operator's compartment; Driving engine is installed in the subframe below, and the subframe front portion is equipped with two front leg struts, and the subframe middle part is equipped with two middle supporting legs; The subframe rear portion is equipped with two rear leg, and subframe afterbody centre portion is equipped with a tail supporting leg, altogether seven supporting legs; Application force when bearing work has jointly reduced the suffered dynamics of each supporting leg widely, makes car load stable more and safety in work.The subframe top is equipped with distributing box, can control the service condition of seven supporting legs simultaneously, and is different when weight, can go operation according to the supporting leg that demand is stretched out some.
Preferably middle supporting leg is equal to the distance between front leg strut and the rear support leg, and it is best that such stablizing effect and lifting effect will reach.
Through above improvement, seven supporting leg electric hoists can be sling and weigh the hundreds of ton very to the weight of last kiloton.Level at home is in a leading position.
Description of drawings
Fig. 1 is the utility model seven supporting leg electric hoist front views.
Among the figure, 1 front leg strut, supporting leg in 2,3 subframes, 4 rear support legs, 5 tail supporting legs, 6 distributing boxs
Fig. 2 is the subframe birds-eye view of the utility model seven supporting leg electric hoists.
Among the figure, 11 front leg struts, supporting leg in 12,14 rear support legs
The specific embodiment
In Fig. 1, a kind of seven supporting leg electric hoists comprise subframe 3, and subframe 3 is provided with turntable, turntable by revolution support with its on swing type mechanism form, through motor-driven, turntable bodywork assembly is relatively done the plane and is rotatablely moved.On the turntable by the back to preceding master winch, radiator, switch box, control cabin and the arm of being equipped with successively; Main suspension hook is installed on the arm, and big arm oil cylinder is connected with arm through hinge with the feeler lever oil cylinder, and the master winch below is equipped with main oil tank; Main oil tank one side is equipped with main oil pump; Subframe 3 is provided with operator's compartment, is provided with bracing frame at the operator's compartment rear side, is used under the situation of not operation, supporting arm.When hoisting heavy, stretch out simultaneously through distributing box 6 control front leg struts 1, middle supporting leg 2 and rear support leg 4 and to get final product, fix supporting leg and begin hoisting heavy; Through seven common operations of supporting leg of distributing box 6 controls; Stable like this safety again, distributing box can distribute oil pressure, stretches out simultaneously.
The above; Be merely the specific embodiment of the utility model; But the protection domain of utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of utility model.
