Abstract

The inventions relaters to a gantry crane with an electric hoist. The gantry crane 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 bottom 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 respectively fixedly connected with two ends of the cross beam; telescopic rods of the first hydraulic cylinders are at the same horizontal plane with the first rolling wheels; the outer side of each guide rail is fixedly connected with a cross rod; outer side walls of bottom ends of the L-shaped supporting seats are respectively fixedly connected with second hydraulic cylinders; L-shaped end parts of pull rods of the second hydraulic cylinders are respectively 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

A kind of electric block gantry crane

Technical field

The present invention relates to 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, be therefore referred to as transfer crane, existing transfer crane complex structure, cost is high, and installation and maintenance cost is high; The electric block that current electric block gantry crane uses, when lifting weight, owing to lacking spacing stop to it, has very large potential safety hazard.

Summary of the invention

The applicant, for above-mentioned shortcoming of the prior art, provides a kind of electric block gantry crane, and its structure is simple, and use flexibly, safe reliability is high, and installation and maintenance cost is low.

The technical solution adopted in the present invention is as follows:

A kind of electric block gantry crane, comprises two " L " shape supporting seats, is provided with crossbeam between the top of two " L " shape supporting seat; The bottom of crossbeam is provided with the first roller, and the first roller is connected with electric block, and 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 are connected the first hydraulic actuating cylinder, and expansion link and first roller of the first hydraulic actuating cylinder are positioned in same level; The outside of guide rail is fixed with cross bar, and the Basolateral 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 below cross bar;

Further technical scheme is as follows:

Be connected by stirrup 11 between the guide rail 8 of described two " L " shape supporting seat 1 bottoms.

Beneficial effect of the present invention is: on crossbeam, arrange hydraulic actuating cylinder, restriction or pushing rolling wheels motion, be connected hydraulic actuating cylinder simultaneously on supporting seat, the motion of restriction hoisting crane on guide rail, add the stability of whole hoisting crane, and structure is simple, use flexibly, safe reliability is high, and installation and maintenance cost is low, has saved the cost of enterprise.

Accompanying drawing explanation

Fig. 1 and Fig. 2 is structural representation of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1, be provided with crossbeam 2 between the top that the present invention includes two " L " shape supporting seat 1, two " L " shape supporting seats 1, 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, second roller 7, the second roller 7 can roll in described guide groove, and hoisting crane occurred level is moved; The two ends of crossbeam 2 are connected the first hydraulic actuating cylinder 5, the expansion link 6 of the first hydraulic actuating cylinder 5 and the first roller 3 are positioned in same level, when the position of electric block 4 determines, starting the first hydraulic actuating cylinder 5 can make expansion link 6 withstand the first roller 3 from two ends, prevent electric block 4 unstable when lifting weight, the first hydraulic actuating cylinder 5 also can promote the first roller 3 in the horizontal direction and move; The outside of guide rail 8 is fixed with cross bar 13, the Basolateral 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 below cross bar 13, after the position of hoisting crane is determined, start the second hydraulic actuating cylinder 9, pull bar 10 is upwards stretched, cross bar 13 is caught in " L " shape end of described pull bar 10, prevent the second roller 7 of hoisting crane from rolling 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, the stability of guide rail 8 can be increased.

More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
