Abstract
The utility model relates to a hydraulic span and height adjustable gantry crane. The gantry crane comprises two supporting legs and a beam spanned on the two supporting legs, wherein the supporting legs comprise telescopic connecting rods and hydraulic lifting devices arranged at the lower ends of the connecting rods. Compared with the prior art, the hydraulic span and height adjustable gantry crane is simple in structure, can be used for hoisting super-long and super-heavy equipment and large steel structures, can also be used for hoisting multiple heavy goods arranged at various places in a plant through assembling a gantry, is suitable for hoisting goods with different lengths and widths through adjusting the span between the two supporting legs and hoisting goods with different heights through adjusting the heights of the two supporting legs, can be used for hoisting equipment with small operating space, and is flexible and convenient in operation.
Description
Technical field
The utility model relates to a kind of lifting, especially relates to the door frame lifting that a kind of fluid pressure type can be adjusted span and height.
Background technology
Along with the development of power industry, increasing substation is under construction, because voltage transformer is as the major equipment of substation, from the purchase of voltage transformer, be transported to the device of laying the voltage transformer that all needs can lifting to sling.Because size and the weight of voltage transformer are increasing, the difficulty of lifting voltage transformer is increasing.
At present, general large-scale crane or the crane barge of adopting of lifting for voltage transformer, but the tonnage of these equipment is generally bigger, and all need bigger place, operating environment is had relatively high expectations, under no loading and unloading condition and space condition were not very abundant situation, these equipment were often lack scope for their abilities, therefore develop a kind of fluid pressure type and can adjust the loading and unloading operation that main equipments such as voltage transformer are carried out in the door frame lifting of span and height.
The utility model content
The purpose of this utility model is exactly to provide a kind of span adjusted simple in structure, practical, applied widely and the door frame lifting of height for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of fluid pressure type can be adjusted the door frame lifting of span and height, this door frame lifting comprises that two supporting legs reach across the crossbeam on two supporting legs, described supporting leg comprises telescopic pipe link and is located at the hydraulic jacking device of pipe link lower end, described telescopic pipe link has 3～5 joints, described pipe link stretches by the drive of hydraulic jacking device, and the height of described supporting leg changes along with the flexible of pipe link.
Described hydraulic jacking device is hydraulic hoisting crane.
Be arranged with suspension ring on the described crossbeam.
The lower end of described supporting leg is arranged on the base.
Described crossbeam changes length along with the distance between two supporting legs, because the span of two supporting legs is variable and the adjustable height of two supporting legs, makes device of the present utility model can be applied to the equipment hoisting of different volumes.
When using device of the present utility model to lift, at first entangle equipment such as voltage transformer by suspension ring and hoist cable or shackle, make that equipment such as voltage transformer are hung on crossbeam, make every effort to make the center of crossbeam to occupy on the center of gravity of equipment, produce when preventing from lifting by crane significantly get rid of pendulum and weight too amesiality, start hydraulic jacking device then, hydraulic jacking device drives the pipe link elongation, at this moment, two supporting legs are supporting crossbeam and are moving up, crossbeam drives equipment upward movements such as voltage transformer, and equipment such as voltage transformer are lifted.
Compared with prior art, the utlity model has following advantage and beneficial effect:
(1) simple in structure, can lift ultralong overweight equipment and large-scale steel structure;
(2) can be by the assembling door frame, lifting is arranged in many heavy goods in each place of factory building;
(3) can be applicable to the lifting of different length and width goods by adjusting the span between two supporting legs;
(4) can be applicable to the lifting of differing heights goods by adjusting the height of two supporting legs;
(5) can be used for the narrow and small equipment hoisting in lifting operation space, operating flexibility is convenient.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 1 is supporting leg, and 2 is pipe link, and 3 is hydraulic jacking device, and 4 is base, and 5 is crossbeam, and 6 is suspension ring.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of fluid pressure type can be adjusted the door frame lifting of span and height, as shown in Figure 1, this door frame lifting comprises that two supporting legs 1 reach across the crossbeam 5 on two supporting legs 1, supporting leg 1 comprises telescopic pipe link 2 and is located at the hydraulic jacking device 3 of pipe link 2 lower ends, wherein, hydraulic jacking device 3 is hydraulic hoisting crane.Telescopic pipe link 2 has 3～5 joints, and pipe link 2 stretches by the drive of hydraulic jacking device 3, and the height of supporting leg 1 changes along with the flexible of pipe link 2.Be arranged with suspension ring 6 on the crossbeam 5.The lower end of supporting leg 1 is arranged on the base 4.
Crossbeam 5 changes length along with the distance between two supporting legs 1, because the span of two supporting legs 1 is variable and the adjustable height of two supporting legs 1, makes device of the present utility model can be applied to the equipment hoisting of different volumes.
When using device of the present utility model to lift, at first entangle equipment such as voltage transformer by suspension ring 6 and hoist cable or shackle, make that equipment such as voltage transformer are hung on crossbeam 5, make every effort to make the center of crossbeam 5 to occupy on the center of gravity of equipment, produce when preventing from lifting by crane significantly get rid of pendulum and weight too amesiality, start hydraulic jacking device 3 then, hydraulic jacking device 3 drives pipe link 2 elongations, at this moment, two supporting legs 1 are supporting crossbeam 5 and are moving up, crossbeam 5 drives equipment upward movements such as voltage transformer, and equipment such as voltage transformer are lifted.
