Abstract
The utility model discloses a quick assembly and disassembly formula gantry crane frame construction, including setting up the same a pair of stabilizer blade of structure on the track of ground both sides respectively, every to the stabilizer blade include preceding landing leg with the back landing leg be provided with the girder between two pairs of stabilizer blades, be provided with under the girder rather than the support frame that links firmly mutually and the direction is unanimous, preceding landing leg with the back landing leg the upper end respectively with the support frame is articulated mutually, and its lower extreme is articulated with rail -engaging wheel support respectively, is close to preceding landing leg and back landing leg lower extreme department are provided with the location pull rod that is used for before fixed landing leg and back landing leg, the locating hole has been offered respectively with the upper end of back landing leg to preceding landing leg, and the locating pin passes the support frame activity peg graft in in the locating hole. The utility model has the advantage of simple structure, the convenience is installed and erect.
Description
Technical field
The utility model relates to hoisting machinery, especially relates to a kind of quick detach ready-package gantry crane frame structure of being convenient to installation and setting up.
Background technology
Gantry crane is the one distortion of bridge crane, is again straddle truck. Be mainly used in the handling operation of outdoor goods yard, stock ground goods, bulk goods. Its metal structure, as door-shaped frame, is installed two legs under support main beam, can directly on the track on ground, walk, and girder two ends can have overhanging cantilever beam. Gantry crane has the features such as utilization of area rate is high, job area large, it is wide to adapt to, highly versatile, is used widely in goods yard, harbour. The frame structure of existing gantry crane is direct welding and sets up and form, the especially welding of leg, and its technique is very complicated, and welding node is many, and stressed complexity is constructed loaded down with trivial details, has greatly increased gantry crane and has set up man-hour used; Make expending of manpower and materials very large, set up cost very high.
Summary of the invention
The utility model object be to provide a kind of simple in structure, be convenient to the quick detach ready-package gantry crane frame structure of installing and setting up.
For achieving the above object, the utility model can be taked following technical proposals:
Quick detach ready-package gantry crane frame structure described in the utility model, comprise and be separately positioned on the identical a pair of leg of structure on two siding tracks of ground, described every pair of leg comprises front leg strut and rear support leg, between described two pairs of legs, be provided with girder, under described girder, be provided with and it is connected mutually and direction is consistent bracing frame, the upper end of described front leg strut and rear support leg is hinged with support frame as described above respectively, its lower end is hinged with track travel wheeling support respectively, be provided with the positioning tie bar for fixing front leg strut and rear support leg near described front leg strut and rear support leg lower end, the upper end of described front leg strut and rear support leg offers respectively locating hole, alignment pin is actively plugged in described locating hole through support frame as described above.
The utility model advantage is simple in structure, installs and sets up conveniently. Leg is changed into the front leg strut and the rear support leg that are hinged with bracing frame, by changing the size of angle between front leg strut and rear support leg, complete like a cork the lifting of bracing frame height; In the time that bracing frame rises to gantry crane and sets up desired height, by locating hole, alignment pin and positioning tie bar, front leg strut and rear support leg are fixed, complete setting up of gantry crane. Simplify installation and the erecting process of gantry crane, reduced difficulty of construction, reduced the input of manpower and materials, greatly reduced man-hour used when installing and setting up, set up cost and significantly reduce.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is I portion enlarged drawing in Fig. 1.
Fig. 3 is front leg strut described in the utility model and the structural representation of rear support leg in open mode.
Detailed description of the invention
As shown in Figure 1, 2, quick detach ready-package gantry crane frame structure described in the utility model, comprise and be separately positioned on the identical a pair of leg of structure on two siding tracks of ground, every pair of leg comprises front leg strut 3 and rear support leg 4, between two pairs of legs, set up girder 1, under girder 1, be provided with the bracing frame consistent with its direction 2, on bracing frame 2, be provided with the brace rod 9 being connected mutually with girder 1. The upper end of front leg strut 3 and rear support leg 4 is hinged with bracing frame 2 respectively, and front leg strut 3 and rear support leg 4 can be rotated along hinge, thereby changes the size of angle between front leg strut 3 and rear support leg 4; The lower end of front leg strut 3 and rear support leg 4 is hinged with rail running wheels 5 bearings respectively, and in the time that bracing frame 2 moves up, two rail running wheels 5 that are positioned on same track are drawn close mutually along track; In the time that bracing frame 2 moves down, two rail running wheels 5 that are positioned on same track are separated from each other along track. Be provided with the positioning tie bar 6 for fixing front leg strut 3 and rear support leg 4 near front leg strut 3 and rear support leg 4 lower ends, the upper end of front leg strut 3 and rear support leg 4 offers respectively locating hole 7, alignment pin 8 is actively plugged in locating hole 7 through bracing frame 2, when bracing frame 2 rises to while setting up the required station of gantry crane, the two ends of positioning tie bar 6 are connected with front leg strut 3 and rear support leg 4 respectively,, alignment pin 8 is inserted in locating hole 7 through bracing frame 2 meanwhile, complete the fixing of described leg.
Quick detach ready-package gantry crane frame structure erection process described in the utility model is as follows:
As shown in Figure 3, in the time of original state, front leg strut 3 and rear support leg 4 are in open mode, and now girder 1 is positioned at its lowest position; For example, when move up under the effect of girder 1 in external force (moving up with crane traction girder 1), drive the bracing frame 2 of its below to move up, bracing frame 2 drives again the upper end of front leg strut 3 and rear support leg 4 to move up, thereby the angle between front leg strut 3 and rear support leg 4 is dwindled gradually, and it is mutually close along track that hinged rail running wheels 5 is distinguished in front leg strut 3 and rear support leg 4 lower ends. As shown in Figure 1, when girder 1 rises to while setting up desired height, alignment pin 8 is inserted in locating hole 7 through bracing frame 2, and the lower end of front leg strut 3 and rear support leg 4 is fixed by positioning tie bar 6, thereby complete setting up of gantry crane framework.
