Abstract
The utility model discloses a telescopic crane big frame. The telescopic crane big frame is characterized in that the front end and the rear end of the big frame are respectively provided with a telescopic hydraulic cylinder; the telescopic hydraulic cylinder is internally provided with a telescopic cylinder shaft; the tail end of the telescopic cylinder shaft is connected with a supporting leg; and the length of the telescopic cylinder shaft is 600-1500mm. The telescopic crane big frame disclosed by the utility model has the advantages that the structure is simple and the use is convenient; the advantages of small size, low center of gravity and convenient and flexible operation of the small crane are maintained, and simultaneously the defects that the small crane is less in longitudinal span, influences the hoisting weight, is easy to roll over and is not safe are solved.
Description
Technical field
The utility model relates to the large frame of hoisting crane, is specifically related to large of a kind of telehoist.
Background technology
That minor crane has is small, center of gravity is low, span is little, flexible operation, characteristics easily, narrow at road, the place is little, under the action radius circlet border operation (operation) very convenient, but owing to vertical span of large of minor crane is little, the span that general minor crane is large is about 2.5 meters, affects hoisting weight, overthrow accident also easily occurs, poor stability, dangerous, seriously restricted being widely used of minor crane.
Summary of the invention
The purpose of this utility model provides large of a kind of telehoist, and is little to solve the vertical span of prior art, the problem that affects hoisting weight and easily tumble.
The utility model comprises support body and supporting leg, solve technical scheme that its technical matters adopts and be under the constant prerequisite of former support body length, install respectively a flexible hydraulic ram additional in the support body front-end and back-end, telescopic oil cylinder links to each other with crane hydraulic system, flexible hydraulic ram inside is provided with the telescopic oil cylinder axle, the telescopic oil cylinder shaft end links to each other with supporting leg, and the telescopic oil cylinder shaft length is 600～1500 millimeters.
Above-mentioned telescopic oil cylinder axle preferred length is 800～1100 millimeters.
The utility model does not change minor crane support body length, utilize oil liquid pressure and conversion to finish the flexible operation of large of hoisting crane by two flexible hydraulic rams, utilize oil liquid pressure to make landing leg stretching, during walking with in the telescopic oil cylinder in the telescopic oil cylinder axle retraction support body, stretch out the telescopic oil cylinder axle during lifting, so just, can increase vertical span of large of hoisting crane, increase stability, reach and lifted by crane stable, large, the safe and reliable purpose of lift heavy amount.
The beneficial effects of the utility model are simple in structure, easy to use, both kept minor crane small, center of gravity is low, flexible operation, advantage easily, solved simultaneously the vertical span of minor crane little, affect hoisting weight, easily tumble, unsafe drawback.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model extended state schematic diagram;
Fig. 2 is the utility model contraction state schematic diagram.
1 support body, 2 supporting legs, 3 flexible hydraulic rams, 4 telescopic oil cylinder axles among the figure.
The specific embodiment
As shown in Figure 1 and Figure 2: large of a kind of telehoist, comprise support body 1 and supporting leg 2, support body 1 front-end and back-end install respectively a flexible hydraulic ram 3 additional, flexible hydraulic ram 3 inside are provided with telescopic oil cylinder axle 4, telescopic oil cylinder axle 4 ends link to each other with supporting leg 2, and the telescopic oil cylinder shaft length is 1000 millimeters.
When the utility model carries out hoisting operation, two flexible hydraulic rams 3 by support body 1 front-end and back-end, utilizing oil liquid pressure to stretch out telescopic oil cylinder axle 4 stretchs out supporting leg, thereby can increase in use 1000 millimeters of vertical spans of large of hoisting crane, just can be with in the telescopic oil cylinder 3 in the telescopic oil cylinder axle 4 retraction support bodys 1 during walking, do not change like this minor crane support body length, just can improve the job stabilization of minor crane, reached and lifted by crane stable, large, the safe and reliable purpose of lift heavy amount.
Claims (2)
