Abstract
The utility model relates to a gantry crane capable of automatically carrying out span variation and belongs to bridge construction equipment. The top end of a flexible support leg of the gantry crane capable of automatically carrying out span variation of the design is provided with a span variation device. The span variation device consists of a span variation beam and two span variation wheels. The span variation wheels are connected with a track below a girder. The span variation device is connected with the girder by an inverted hook so that the span variation device and the girder cannot be separated from each other. The bottom parts of the rigid support leg and the flexible support leg are respectively connected with corresponding large vehicles by rotary supporting devices to take corresponding coordinated motion. The gantry crane of the design, which is used for a bridge erecting machine to erect section blocks with different widths, completes operation of erecting the section blocks under the premise condition of not increasing the amount of the cranes when the bridge erecting machine changes a span, does not need additional power and can automatically realize span variation. When the width of a track gauge and the angle of the track are changed, the large vehicles can be automatically adaptive. The gantry crane can also effectively prevent the rail gnawing phenomenon, saves time and labor and is efficient and safe.
Description
Technical field
The utility model is a kind ofly can become the straddle type gauntry crane automatically, belongs to bridge construction equipment, is specifically related to the weight-lifting equipment of prefabricated subsection assembly unit bridge formation machine.
Background technology
Gauntry crane has very important effect in the use of bridge formation machine, present bridge formation machine both domestic and external generally is to adopt traditional gauntry crane to implement lifting sections piece.The tradition gauntry crane generally has two kinds of versions.That is: (1) two firm leg, (2) one is firm gentle.The gauntry crane of these two kinds of structures all can not change span.But because the bridge bending spring that this bridge formation machine is set up is less, and the width of bridge is different.The tradition gauntry crane can not change span, can not set up the sections piece of different in width, so can not satisfy construction requirement.
The utility model content
The purpose of this utility model provides and a kind ofly can become the straddle type gauntry crane automatically, under the prerequisite that does not increase auxiliary power, realizes that hoisting crane changes span automatically, not only improves operating efficiency, and reduces construction cost.
The utility model purpose is achieved by the following technical solution: originally can become the straddle type gauntry crane automatically, comprise girder, cart, rigid leg and flexible leg, captive joint with girder by bolt in the rigid leg top, characteristics are that the flexible leg top is provided with and becomes straddle mounting and put, this change straddle mounting is put and is striden beam and two by a change and become back gears and form, becoming back gear is connected with the track of girder below, the change straddle mounting is put then and is had anti-hook to link between the girder, and the bottom of described rigid leg and flexible leg is connected by the cooresponding cart of rotary supporting device and its respectively.
The design's flexible leg top is put with girder and is connected by becoming straddle mounting, and become that straddle mounting is put and girder between have anti-hook to link, the change straddle mounting is put with girder can not throw off.In addition, owing to be connected with its cart separately through pivoting support respectively in the bottom of rigid leg and flexible leg, so can do the corresponding coordinated movement of various economic factors by the pivoting support effect of rigidity, flexible two supporting legs when flexible leg can be striden by the track change with the cart of hoisting crane, the realization balance becomes strides.Promptly when crane operation gauge width or track changes in pitch, flexible leg puts to become along girder automatically and stride through becoming straddle mounting, thereby the automatic change that realizes hoisting crane is striden under the effect of this external force.
The design's frame that is used to build bridge is established the gauntry crane of different in width sections piece, when the bridge formation machine changes span, under the precondition that does not increase lifting board number, finish the work of setting up the sections piece, hoisting crane does not need extra power, can realize automatically becoming and strides, when the angle of the width of gauge and track changes, cart can adapt to automatically, can also effectively prevent to gnaw the rail phenomenon.Laborsaving saving time, highly effective and safe.
Description of drawings

Fig. 2 is that the utility model flexible leg A-A is to scheme drawing
Fig. 3 is the utility model flexible leg and girder connection diagram
The specific embodiment
How now further specify the utility model in conjunction with the accompanying drawings implements:
Two supporting legs of this hoisting crane, a leg is a rigid leg 2, a leg is a flexible leg 3, flexible leg 3 tops are provided with the change straddle mounting and put 4, this change straddle mounting is put 4 and is striden beam 4.1 and two by a change and become back gears 4.2 and forms, becomes back gear 4.2 and is connected with the track of girder 1 below, and the change straddle mounting is put between 4 and the girder 1 and passed through anti-hook 4.3 connections, the change straddle mounting is put with the girder mutual restriction can not throw off, the bottom of rigid leg and flexible leg is connected by the cooresponding cart 6 of rotary supporting device 5 and its respectively.
The change straddle mounting is put function class and is similar to crane, and when the hoisting crane traveling, the cart 6 of hoisting crane can be according to the variation automatic compensation of gauge.Along with gauge broadens or narrows down, track just has to cooresponding outside thrust of cart and inside pulling force.This power is passed to gentle leg 3 by cart, put 4 through the change straddle mounting and stride along girder 1 change automatically, thereby the automatic change that realizes hoisting crane is striden.
Claims (2)
1. one kind becomes the straddle type gauntry crane automatically, comprise girder, cart, rigid leg and flexible leg, captiveing joint with girder by bolt in the rigid leg top, it is characterized in that flexible leg (3) top is provided with to become straddle mounting and put (4), and this changes straddle mounting is put (4) and striden beam (4.1) by a change and two change back gears (4.2) are formed, become back gear (4.2) and be connected with the track of girder (1) below, the change straddle mounting is put between (4) and the girder (1) has anti-hook (4.3) to link.
2. according to the described automatic change straddle type gauntry crane of claim 1, it is characterized in that the bottom of rigid leg (2) and flexible leg (3) is connected with its cooresponding cart (6) by rotary supporting device (5) respectively.
