The gantry crane is capable of lifting goods higher at a low cost.
Description
Technical field
The present invention relates to shipyard gauntry crane, particularly relate to a kind of upper dolly and be fixed the shipyard gauntry crane hung.
Background technology
The mankind facilitate the development of ship building industry to the continuous utilization of marine resources and exploitation, and shipyard gauntry crane is a kind of visual plant in ship building industry.The structure normally form going up dolly and coordinate subordinate's dolly of traditional shipyard gauntry crane, lifting altitude is generally equal to or less than the height of girder lower surface.
The application such as current offshore platform increases day by day for the requirement of lifting altitude, and improves lifting altitude will significantly increase the cost of shipyard gauntry crane by increasing main depth of beam.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of upper dolly and is fixed the shipyard gauntry crane hung, and can improve lifting altitude with lower cost.
For solving the problems of the technologies described above, the invention provides a kind of upper dolly and being fixed the shipyard gauntry crane hung, comprising:
Girder;
Be arranged on the lower dolly on described girder and upper dolly, described lower dolly and below of getting on or off the bus are respectively arranged with main suspension hook;
Be provided with above described upper dolly and fixedly hang.
Alternatively, described fixing bull ladle is drawn together:
The arm extended laterally above the trolley frame of described upper dolly, described side direction refers to the direction perpendicular to described girder bearing of trend;
Be arranged on the side suspension hook of described arm end.
Alternatively, the trolley frame of described upper dolly is also provided with the side lifting mechanism driving described side suspension hook.
Alternatively, also running gear for trolley is installed below the trolley frame of described upper dolly.
Alternatively, the quantity of the main suspension hook below described upper dolly is 2, and the quantity of the main suspension hook below described lower dolly is 1.
Alternatively, the two ends of described girder are separately installed with rigid leg and flexible leg.
Compared with prior art, the present invention has the following advantages:
The shipyard gauntry crane of the embodiment of the present invention installs additional and fixedly hangs above upper dolly, is moved by the cooperation of dolly and cart, freely can lift and require higher segmentation to lifting altitude, compared with increasing the mode of girder terrain clearance, less on the impact of cost.
Further, in the shipyard gauntry crane of the embodiment of the present invention, below upper dolly, be provided with 2 main suspension hooks, below lower dolly, be provided with 1 main suspension hook, 3 suspension hooks stand up with the use of realizing the function lifted, and install additional above upper dolly fixedly hang the realization not affecting and stand up and lift function.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the invention will be further described, but should not limit the scope of the invention with this.
With reference to figure 1 and Fig. 2, the shipyard gauntry crane of the present embodiment comprises: girder 1, rigid leg 2, flexible leg 3, upper dolly 5, lower dolly 6, maintenance crane 7, cart walking mechanism 8.
Wherein, rigid leg 2 and flexible leg 3 are arranged on the two ends of girder 1 respectively.Such as, flexible leg 3 can be hinged by flexible hinge 4 and girder 1.
Lower dolly 5 and upper dolly 6 are arranged on girder 1, and lower dolly 5 and upper dolly 6 can be walked independently of each other on girder 1.Main suspension hook (not indicating in figure) is respectively arranged with below lower dolly 5 and upper dolly 6, in the present embodiment, the main suspension hook quantity arranged below lower dolly 5 is 1, the main suspension hook quantity arranged below upper dolly 6 is 2, and 3 main suspension hooks that lower dolly 5 and upper dolly 6 are installed can lift function with the use of realizing standing up.
In addition, the top of girder 1 is provided with maintenance crane 7, and the bottom of whole shipyard gauntry crane is provided with cart walking mechanism 8.By cart walking mechanism 8, shipyard gauntry crane along being laid on ground track travel, can realize the movement of shipyard gauntry crane.
With reference to figure 3 to Fig. 5, the upper dolly of the present embodiment comprises trolley frame 51, main hoisting mechanism 52, main suspension hook 54, running gear for trolley 56, also adds and fixedly hang above this outside upper dolly.
Furthermore, this fixing bull ladle draws together the arm 57 extended laterally above the trolley frame 51 of upper dolly and the side suspension hook 55 being arranged on arm 57 end.It should be noted that, " side direction " herein refers to the direction perpendicular to girder bearing of trend.
Particularly, arm 57 can stretch out from any side girder both sides.Because the arm 57 fixedly hung extends laterally, in order to avoid affecting the balance of gauntry crane during lifting, clump weight can be added on upper dolly and/or girder.
Trolley frame 51 is provided with main hoisting mechanism 52 and side lifting mechanism 53, wherein main hoisting mechanism 52 is for the main suspension hook 54 of drive installation below trolley frame 51, and side lifting mechanism 53 is for driving the main suspension hook 54 fixedly hung.When reality uses, be fixed on by parts to be lifted on side suspension hook 55, side lifting mechanism 53 drive side suspension hook 55 hoists, thus is sling by these parts.
In addition, installation carriage traveling gear 56 is gone back in the below of trolley frame 51, walks along girder for driving described upper dolly.
Fig. 6 and Fig. 7 respectively illustrates the canoe of main hoisting mechanism in dolly and side lifting mechanism, and wherein main hoisting mechanism adopts the canoe having row's rope, and side lifting mechanism adopts the canoe without row's rope.
The shipyard gauntry crane of the present embodiment in use, can be moved by the cooperation of dolly and traveling gear of getting a lift, employing is fixedly hung the parts treating lifting and is lifted, and because fixedly hanging of the present embodiment is arranged on above upper dolly, thus its lifting altitude can higher than girder lower surface.And fixedly hang and be arranged on above dolly, standing up that three main suspension hooks that also can't affect on dolly and lower dolly can realize lifts function.
In addition, improve compared with lifting altitude with traditional by the mode raising girder terrain clearance, the impact of technical scheme on cost of the present embodiment is less, is conducive to the complete machine manufacturing cost reducing shipyard gauntry crane, has significant economic benefit.
Although the present invention with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible variation and amendment, the scope that therefore protection scope of the present invention should define with the claims in the present invention is as the criterion.
