Abstract

The utility model discloses a double-upper trolley gantry crane, which comprises two upper trolleys which operate on an upper track of a girder, and a lower trolley which operates on a lower track of the girder, wherein each upper trolley is provided with two lifting hooks, and the lower trolley is provided one lifting hook. The upper trolleys are matched with the lower trolley to ensure the traditional overturn function not to be influenced, and any upper trolley can be combined with the lower trolley to work, so subsection overturn is realized. Each upper trolley is provided with two lifting hooks, the covering range of the four lifting hooks of the two upper trolleys is rectangular during the lifting operation, and the covering area is increased by one time; and because the covering area is increased, the lifting stability is also greatly increased.

Description

Two dolly gauntrys crane of going up
Technical field
The utility model relates to the hoisting crane field, more particularly, relates to a kind of gauntry crane.
Background technology
Gauntry crane is also referred to as gauntry crane and is used for building berth assembly unit hull, and standing have two crane carriages: one has two suspension hooks, moves on the track of girder crane span structure top flange; Another has a suspension hook, moves on the track of girder crane span structure lower flange, and two crane carriage cooperations are so that the body section of upset and hoisting large-size up and down.
Human utilization and exploitation to marine resources have promoted the development of ship building industry, also hang to ship-building gantry and have higher requirement.Little tonnage, the gauntry crane of little span have not satisfied the needs that shipyard is produced, and dock degree of utilization contradiction low and the production capacity deficiency becomes increasingly conspicuous.Big span, the large-tonnage gauntry crane becomes gauntry crane and develops a kind of trend, this 3 of the last dolly of two suspension hooks of traditional dragon gantry crane and the following dolly of a suspension hook lift mode of operation and limited segmentation and continue to maximize: the suspension centre overlay area is a triangle, the center of gravity of suspended object must be within the scope of triangle subregion, therefore at present the traditional dragon gantry crane biggest lifting capacity generally all is no more than 1000t, and this wants to continue to maximize by segmentation provides dock efficient to cause technical bottleneck.
According to above requirement, just need a kind of later-model gauntry crane to overcome the difficulty of prior art.
The utility model content
The utility model is intended to propose a kind of two dolly gauntry crane of going up.
According to an embodiment of the present utility model, a kind of two dolly gauntry crane of going up is proposed, comprise that two ones run on the last dolly that gets on the right track of girder and the following dolly of a lower railway that runs on girder, wherein dolly has two suspension hooks in each one, and following dolly has a suspension hook.
In one embodiment, two dolly gauntrys crane of going up comprise: girder, and the upside of girder is equipped with and gets on the right track, and the downside of girder is equipped with lower railway; Two legs are connected respectively to the two ends of girder, and leg moves on ground rail.
In one embodiment, go up the common coverage that lifts that limits a rectangle of dolly for two ones, corresponding two positions of going up four suspension hooks of dolly, four tops that lift coverage of described rectangle.
Two dolly gauntry crane of going up of the present utility model has following advantage:
1) two last dollies that hoisting capacity is identical, it is unaffected to guarantee traditional function of standing up to keep traditional following dolly, and any one one go up dolly can both with following dolly work compound realization sectional turn-over.
2) go up dolly and have two suspension hooks for every, when lifting operation two ones to go up four suspension hook coverages of dolly be rectangle, the overlay area increases and is twice; Because the increase of overlay area, the stability during lift heavy also strengthen greatly.
Description of drawings
The above and other feature of the present utility model, character and advantage will become more obvious by the description below in conjunction with drawings and Examples, in the accompanying drawings, identical Reference numeral is represented identical feature all the time, wherein:
Fig. 1 has disclosed the two constructionals drawing of going up the dolly gauntry crane according to an embodiment of the present utility model.
The specific embodiment
With reference to figure 1, the utility model proposes a kind of two dolly gauntry crane of going up and solve problems of the prior art.As shown in Figure 1, the last dolly gauntry crane 300 of this pair comprises:
Girder 301, the upside of girder 301 is equipped with and gets on the right track 302, and the downside of girder 301 is equipped with lower railway 303.Two legs 401 and 402 are connected respectively to the two ends of girder 301, and two legs 401 and 402 move on ground rail.
Dolly 100 in two ones of the operations of getting on the right track on 302 of girder, operation one subordinate's dolly 200 on the lower railway 303 of girder, wherein dolly 100 has two suspension hooks 101 in each one, and following dolly 200 has a suspension hook 201.
Go up the dolly 100 common coverages that lift that limit a rectangle, corresponding two positions of going up four suspension hooks 101 of dolly 100, four tops that lift coverage of this rectangle for two ones.
Two dolly gauntry crane of going up of the present utility model possesses following advantage:
1) adopt two last dollies that hoisting capacity is identical, it is unaffected to guarantee traditional function of standing up to keep traditional following dolly, and on any one one dolly can both with following dolly work compound realization sectional turn-over.
2) go up dolly and have two suspension hooks for every, when lifting operation two ones to go up four suspension hook coverages of dolly be rectangle, the overlay area increases than original triangle and is twice; Just because of the increase of overlay area, the stability during lift heavy also strengthens greatly.
The foregoing description provides to being familiar with the person in the art and realizes or use of the present utility model; those skilled in the art can be under the situation that does not break away from utility model thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection domain of the present utility model do not limit by the foregoing description, and should be the maximum range that meets the inventive features that claims mention.
