Abstract
The utility model relates to a crane, in particular to a multi-trolley and double-girder gantry crane. According to the multi-trolley and double-girder gantry crane, the technical problems that the structure of the crane is relatively complex, the hoisting tonnages of the trolleys are constant, the hoisting demands on various goods cannot be met, the production cost is higher, the assembling, setting-up and moving are not easily realized and the like in the prior art are mainly solved. The multi-trolley and double-girder gantry crane comprises two lower cross beams (1) which are arranged in parallel and is characterized in that a pair of support legs (2) is respectively linked to each lower cross beam; two girders (3) which are arranged in parallel are arranged between the two pairs of support legs; more than two movable trolleys (4) with different bearing tonnages are connected onto two girders in a sliding way; a lifting hook device (5) is connected to each movable trolley; and saddle frames (6) are connected onto the two girders.
Description
Technical field
The utility model relates to a kind of hoisting crane, especially relates to the two girder gauntry cranes of a kind of many dollies.
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 the lifting tonnage of dolly is constant, is not suitable for the needs of multiple goods lifting, and productive costs is higher, and assembling is built, moves also comparatively difficult.
The utility model content
The utility model provides the two girder gauntry cranes of a kind of many dollies; It mainly is that to solve the structure of existing in prior technology hoisting crane comparatively complicated; And the lifting tonnage of dolly is constant; Be not suitable for the needs of multiple goods lifting, 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:
The two girder gauntry cranes of a kind of many dollies of the utility model; Comprise two cross sills that laterally arrange; On the described every cross sill all chain be connected to a pair of supporting leg, set up two girders that laterally arrange between two pairs of supporting legs, slidely connect on two girders and carry the travelling car that tonnage has nothing in common with each other more than two; Each travelling car is connected with cargo hook gear, is connected with the saddle frame on two girders.
As preferably, described supporting leg is provided with control cabin, and control cabin connects ground and girder through stair.
As preferably,
Therefore, the utility model is provided with many travelling cars that tonnage is different on girder, makes it can lift different types of goods, and Applicable scope is wider, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: the two girder gauntry cranes of a kind of many dollies of this example like Fig. 1, comprise two cross sills 1 that laterally arrange; On every cross sill all chain be connected to set up between 2, two pairs of supporting legs of a pair of supporting leg to slidely connect on 3, two girders of two girders that laterally arrange and carry the travelling car 4 that tonnage has nothing in common with each other more than two; Each travelling car is connected with cargo hook gear 5; Be connected with saddle frame 6 on two girders, supporting leg is provided with control cabin 7, and control cabin is through stair 8 connection ground and girder 3.
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. two girder gauntry cranes of dolly more than a kind; Comprise two cross sills (1) that laterally arrange; It is characterized in that on the described every cross sill that all chain is connected to a pair of supporting leg (2), set up two girders (3) that laterally arrange between two pairs of supporting legs, slidely connect on two girders and carry the travelling car (4) that tonnage has nothing in common with each other more than two; Each travelling car is connected with cargo hook gear (5), is connected with saddle frame (6) on two girders.
2. the two girder gauntry cranes of a kind of many dollies according to claim 1 is characterized in that described supporting leg (2) is provided with control cabin (7), and control cabin connects ground and girder (3) through stair (8).
