Abstract
The utility model relates to a crane, and in particular relates to a shipbuilding portal crane with a rail clamping device, which mainly solves the technical problems of the crane in the prior art that the structure is complicated, the strength is poor, the production cost is high, the assembling, construction and maintenance are not easy and the like. The shipbuilding portal crane comprises a bottom girder (1) and is characterized in that two pairs of supporting legs (2) are erected on the bottom girder (1); the upper ends of the supporting legs are connected with a large girder (3); the large girder is slidingly connected with a main trolley (4) through a guide rail; the upper part of the main trolley is provided with a rotatable suspension arm (7); the suspension arm is slidingly connected with a main lifting hook device (8); and the lower part of the bottom girder is provided with a cart walking mechanism (9); a clamping rail anchoring device is arranged in the middle of the bottom girder (1).
Description
Technical field
The utility model relates to a kind of hoisting crane, especially relates to a kind of ship-building gantry crane with rail clamping device.
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 with rail clamping device, 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 with rail clamping device 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 through guide rail on the crossbeam, main carriage top is provided with rotating arm, slidely connects main cargo hook gear on the arm; The bottom girder bottom is provided with cart walking mechanism, and the bottom girder middle part is provided with folder rail anchoring device.
As preferably, described secondary dolly bottom is connected with electric block.
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 with rail clamping device of this example like Fig. 1, comprises bottom girder 1; Described bottom girder 1 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 through guide rail on the crossbeam; Main carriage top is provided with rotating arm 7; Slidely connect main cargo hook gear 8 on the arm, the bottom girder bottom is provided with cart walking mechanism 9, and the bottom girder middle part is provided with folder rail anchoring device 10.Secondary dolly bottom is connected with electric block 6.
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.
