Abstract
The utility models relaters to a gantry crane with an electric hoist. The gantry crane with an electric hoist comprises two L-shaped supporting seats, wherein a cross beam is mounted between tops of the two L-shaped support seats; first rolling wheels are arranged at the lower end of the cross beam; the first rolling wheels are connected with the electric hoist; a wire rope stretches from the bottom of the electric hoist and is connected to a hook; bottom ends of the L-shaped supporting seats are provided with second rolling wheels arranged in guide grooves of guide rails; first hydraulic cylinders are fixedly connected with two ends of the cross beam; telescopic rods of the first hydraulic cylinders and the first rolling wheels are at the same horizontal level; cross rods are fixedly connected with the outer side of the guide rails; second hydraulic cylinders are fixedly connected with outer side walls of bottom ends of the L-shaped supporting seats; L-shaped end parts of pull rods of the second hydraulic cylinders are arranged below the cross rods. The gantry crane with the electric hoist is simple in structure, flexible in use, high in safe reliability, and low in mounting and maintenance cost.
Description
Technical field
The utility model relates to the hoisting crane technical field, especially a kind of transfer crane.
Background technology
When outdoor hoisting operation, generally can use transfer crane equipment, because of its outer image " door " word, therefore be referred to as transfer crane, existing transfer crane complex structure, cost is high, and the installation and maintenance cost is high; The electric block that electric block gantry crane is used at present, when the lifting weight, owing to it being lacked to spacing stopping, has very large potential safety hazard.
The utility model content
The applicant, for above-mentioned shortcoming of the prior art, provides a kind of electric block gantry crane, and it is simple in structure, uses flexibly, and safe reliability is high, and the installation and maintenance cost is low.
The technical scheme that the utility model adopts is as follows:
A kind of electric block gantry crane, comprise two " L " shape supporting seats, between the top of two " L " shape supporting seat, crossbeam is installed; The bottom of crossbeam is provided with the first roller, and the first roller is connected with electric block, and the cable wire connecting shackle is stretched out in the bottom of electric block; The bottom of " L " shape supporting seat is with the second roller, and the second roller is positioned at the guide groove of guide rail; The two ends of crossbeam first hydraulic actuating cylinder that is connected, the expansion link of the first hydraulic actuating cylinder and the first roller are positioned on same level; The outside of guide rail is fixed with cross bar, and the bottom lateral wall of " L " shape supporting seat is fixed with the second hydraulic actuating cylinder, and " L " shape end of the pull bar of the second hydraulic actuating cylinder is positioned at the cross bar below;
Further technical scheme is as follows:
Between the guide rail 8 of described two " L " shape supporting seat 1 bottoms, by stirrup 11, be connected.
The beneficial effects of the utility model are: hydraulic actuating cylinder is set on crossbeam, restriction or pushing rolling wheels motion, hydraulic actuating cylinder is connected simultaneously on supporting seat, limit the motion of hoisting crane on guide rail, increased the stability of whole hoisting crane, and simple in structure, use flexibly, safe reliability is high, and the installation and maintenance cost is low, has saved the cost of enterprise.
The accompanying drawing explanation
Fig. 1 and Fig. 2 are structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises between the top of two " L " shape supporting seats 1, two " L " shape supporting seat 1 crossbeam 2 is installed, and crossbeam 2 is T-shaped; The bottom of crossbeam 2 is provided with the first roller 3, and preferably, the first roller 3 is symmetrically set in the both sides of crossbeam 2, and the first roller 3 is connected with electric block 4, and cable wire connecting shackle 12 is stretched out in the bottom of electric block 4; The bottom of " L " shape supporting seat 1 is positioned at the guide groove of guide rail 8 with the second roller 7, the second rollers 7, the second roller 7 can roll in described guide groove, and the hoisting crane occurred level is moved; The two ends of crossbeam 2 first hydraulic actuating cylinder 5 that is connected, the expansion link 6 of the first hydraulic actuating cylinder 5 and the first roller 3 are positioned on same level, when the location positioning of electric block 4 good, starting the first hydraulic actuating cylinder 5 can make expansion link 6 withstand the first roller 3 from two ends, prevent that electric block 4 is unstable when the lifting weight, the first hydraulic actuating cylinder 5 also can promote the first roller 3 motions in the horizontal direction; The outside of guide rail 8 is fixed with cross bar 13, the bottom lateral wall of " L " shape supporting seat 1 is fixed with the second hydraulic actuating cylinder 9, " L " shape end of the pull bar 10 of the second hydraulic actuating cylinder 9 is positioned at cross bar 13 belows, after the location positioning of hoisting crane, start the second hydraulic actuating cylinder 9, make pull bar 10 upwards flexible, cross bar 13 is caught in " L " shape end of described pull bar 10, the second roller 7 that prevents hoisting crane rolls in the guide groove of guide rail 8, preferably, be connected by stirrup 11 between the guide rail 8 of two " L " shape supporting seat 1 bottoms, can increase the stability of guide rail 8.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
