Abstract
The utility model relates to a crane, in particular to a shipbuilding gantry crane, and mainly solves the technical problems that the crane is complex in structure, low in strength, high in production cost and difficult in assembly, construction and maintenance and the like in the prior art. The shipbuilding gantry crane comprises a bottom beam (1), and is characterized in that two pairs of supporting legs (2) are erected on the bottom beam (1); the upper ends of the supporting legs are connected with a crossbeam (3); a primary trolley (4) and a secondary trolley (5) are connected to the crossbeam through a guide rail in a sliding mode; the bottom of the secondary trolley is connected with an electric hoist (6); the upper part of the primary trolley is provided with a rotatable lifting arm (7); a main lifting hook device (8) is connected to the lifting arm in a sliding mode; and the lower part of the bottom beam is provided with cart traveling mechanisms (9).
Description
Technical field
The utility model relates to a kind of hoisting crane, especially relates to a kind of ship-building gantry crane.
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 intensity is relatively poor, and productive costs is higher, and assembling is built, keeps in repair also comparatively difficult.
The utility model content
The utility model provides a kind of ship-building gantry crane, and it mainly is that to solve the structure of existing in prior technology hoisting crane comparatively complicated, and intensity is relatively poor, and productive costs is higher, and the technical matters that also comparatively is difficult for etc. is built, keeped in repair in assembling.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
A kind of ship-building gantry crane of the utility model comprises bottom girder, and described bottom girder is put on the shelf and is provided with two pairs of supporting legs; The supporting leg upper end is connected with crossbeam; Slidely connect main carriage and secondary dolly through guide rail on the crossbeam, secondary dolly bottom is connected with electric block, and main carriage top is provided with rotating arm; Slidely connect main cargo hook gear on the arm, the bottom girder bottom is provided with cart walking mechanism.
As preferably, be provided with folder rail anchoring device in the middle part of the described bottom girder.
Therefore, the utility model is relatively simple for structure, and intensity is stronger, and the assembling, the maintenance all more or less freely, productive costs is lower.
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: a kind of ship-building gantry crane of this example like Fig. 1, comprises bottom girder 1; Bottom girder is put on the shelf and is provided with two pairs of supporting legs 2, and the supporting leg upper end is connected with crossbeam 3, slidely connects main carriage 4 and secondary dolly 5 through guide rail on the crossbeam; Secondary dolly bottom is connected with electric block 6; Main carriage top is provided with rotating arm 7, slidely connects main cargo hook gear 8 on the arm, and the bottom girder bottom is provided with cart walking mechanism 9.The bottom girder middle part is provided with folder rail anchoring device 10.
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)
