Abstract
The utility model relates to a crane and especially relates to a gantry lifting hook crane. The utility model mainly solves such technical problems of the crane in the prior art as complicated structure, poor strength, high production cost and difficult assembly, installation and maintenance. The gantry lifting hook crane provided by the utility model comprises a pair of supporting legs (1) and is characterized in that the bottom parts of the supporting legs (1) are connected with a mudsill (2), rollers (3) are arranged on the mudsill, a main beam (4) is fixed at the top ends of the supporting legs, a travelling car (5) is connected with the main beam in a sliding manner, the front end of the travelling car stretches out of the main beam and is connected with a lifting hook device (6), staircase platforms (7) are spanned at the middle parts of the supporting legs, and the staircase platforms are respectively used for connecting the main beam to the ground through staircases.
Description
Technical field
The utility model relates to a kind of hoisting crane, especially relates to a kind of gate-type suspension hook hoisting 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 gate-type suspension hook hoisting 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 gate-type suspension hook hoisting crane of the utility model comprises a pair of supporting leg, and the bottom of described supporting leg is connected with bottom girder; Bottom girder is provided with roller; The top of supporting leg is fixed with girder, slidely connects travelling car on the girder, and the travelling car front end stretches out outside the girder and is connected with cargo hook gear; Landing has been set up at the middle part of supporting leg, and landing connects girder respectively in ground through stair.
As preferably, described bottom girder end is provided with rail clamping device.
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 gate-type suspension hook hoisting crane of this example like Fig. 1, comprises a pair of supporting leg 1; The bottom of supporting leg is connected with bottom girder 2, and bottom girder is provided with roller 3, and the top of supporting leg is fixed with girder 4; Slidely connect travelling car 5 on the girder; The travelling car front end stretches out outside the girder and is connected with cargo hook gear 6, and landing 7 has been set up at the middle part of supporting leg, and landing connects girder respectively in ground through stair.The bottom girder end is provided with rail clamping device 8.
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)
