Abstract
The utility model relates to a crane, and particularly relates to a crane with inverse U-shaped landing legs. The crane mainly solves the technical problems of the conventional crane in the prior art that the structure is relatively complicated, the production cost is relatively high, the assembly, the construction and the movement are not relatively easy and the like. The crane provided by the utility model comprises two end beams (1) which are symmetrically arranged, and the crane characterized in that two landing legs (2) are fixedly arranged on the two end beams (1); the upper ends of the two landing legs on the same end beam are connected with arched beams (3), and the arched beam and the two landing legs form an inverse U shape; and a main beam (4) is connected between the two arched beams, the main beam is provided with a guide rail (5), and the guide rail (5) is in sliding connection with an electric hoist (6).
Description
Technical field
The utility model relates to a kind of hoisting crane, especially relates to a kind of hoisting crane with the inverted U supporting leg.
Background technology
Weight-lifting equipment is divided into transfer crane, crane in bridge type, beam crane and boom crane by device structure; Wherein transfer crane mainly representative equipment be gauntry crane; Crane in bridge type mainly representative equipment is the bridge formation machine, and boom crane mainly representative equipment is a tower crane.Transfer crane is mainly used in work operations such as the up-down, parallel motion of building ground, factory floor and shipyard harbour weight.Transfer crane mainly is made up of lifting overhead traveling crane, girder, supporting leg, traveling gear and electric hydraulic system.Its principle of work is: utilize the lifting overhead traveling crane that is installed on the girder that weight is raised up; The supporting leg upper end connects girder; The lower end connects with traveling gear, through being installed in the driving of motor on the traveling gear, realizes the effect that hoisting crane moves on rail; The overhead traveling crane of lifting simultaneously also can be walked on girder, realizes at last weight is hung the effect that moves on to another place from a place.But the structure of these hoisting cranes is comparatively complicated, and productive costs is higher, and assembling is built, moves also comparatively difficult.
The utility model content
The utility model provides a kind of hoisting crane with the inverted U supporting leg, and it mainly is that to solve the structure of existing in prior technology hoisting crane comparatively complicated, and productive costs is higher, and the technical matters that also comparatively is difficult for etc. is built, moved in assembling.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
A kind of hoisting crane of the utility model with the inverted U supporting leg; Comprise symmetrically arranged two butt beams, all be fixed with two supporting legs on the described two butt beams, two supporting leg upper ends on the same butt beam are connected with arched beam; Arched beam and two supporting legs are formed inverted U; Be connected with girder between two arched beams, girder is provided with guide rail, slidely connects electric block on the guide rail.
As preferably, described supporting leg is provided with stair and connects ground and hoisting crane top.
Therefore, the utility model relatively simple for structure, assembling, maintenance are all more or less freely, and productive costs is lower.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is construction profile scheme drawings of Fig. 1.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: a kind of hoisting crane with the inverted U supporting leg of this example like Fig. 1, Fig. 2, comprises symmetrically arranged two butt beams 1; All be fixed with two supporting legs 2 on the two butt beams; Two supporting leg upper ends on the same butt beam are connected with arched beam 3, and arched beam and two supporting legs are formed inverted U, are connected with girder 4 between two arched beams; Girder is provided with guide rail 5, slidely connects electric block 6 on the guide rail.Supporting leg is provided with stair 7 connection ground and hoisting crane top.
The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
Claims (2)
1. hoisting crane with the inverted U supporting leg; Comprise symmetrically arranged two butt beams (1), it is characterized in that all being fixed with two supporting legs (2) on the described two butt beams (1) that two supporting leg upper ends on the same butt beam are connected with arched beam (3); Arched beam and two supporting legs are formed inverted U; Be connected with girder (4) between two arched beams, girder is provided with guide rail (5), slidely connects electric block (6) on the guide rail.
