Abstract

The utility model provides a foldable loop wheel machine comprises base, landing leg, stand, cantilever, jack etc. and there is the walking wheel landing leg and base bottom, and its characterized in that base lower part is fixed with four walking wheels, can support loop wheel machine free movement, and landing leg and base have the locating hole with the round pin hookup on landing leg and the base, can become the U-shaped with the bolt with landing leg and base and fix at horizontal position, or stick up the back with the landing leg around the round pin rotation and fix in folding position. Because the utility model discloses a landing leg can stick up foldingly, therefore area reduces greatly, removes convenient in a flexible way, and it is also more convenient to fold, and the suitability is good.

Description

Foldable crane

The utility model relates to loading machine---the folding loop wheel machine of loop wheel machine, particularly supporting leg.

TL-1402 type 925 loop wheel machines that Wanjian General Machinery Plant, Tongling produces, be made up of base, column, jack, cantilever etc., base is a U-shaped, and two supporting legs can telescopically be fixed on base U-shaped open end, there is road wheel base and supporting leg lower end, and by common load-bearing of road wheel and jenny.Although this loop wheel machine supporting leg can shrink, because the limited length of shrinking, floor area is bigger, moves comparatively inconvenience.

The purpose of this utility model is to provide a kind of supporting leg to shrink that the back floor area is little, the loop wheel machine of conveniently moving.

By the loop wheel machine that the utility model proposes, comprise base, two supporting legs, column, cantilever, jack, road wheel is arranged at the bottom of supporting leg and base, the quantity that it is characterized in that the road wheel of base lower end can support loop wheel machine and move freely, supporting leg connects with bearing pin with base, constitute the revolution width of cloth, on supporting leg and the base knock hole is arranged, with latch by the knock hole on supporting leg and the base, can become U-shaped to be fixed on level attitude with base supporting leg, or supporting leg is fixed on the folding position with base after the bearing pin rotation is holded up.

Because it is folding that supporting leg of the present utility model can be holded up, thereby floor area reduces greatly, conveniently moving is flexible, and folding also more convenient, and applicability is good.

Fig. 1 is the utility model working state structure scheme drawing.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is the utility model folded state scheme drawing.

Below in conjunction with accompanying drawing the utility model is further described.

By shown in Figure 1, column 3, cantilever 1, jack 2 constitutes four-bar linkage, column 3 is by base 14 and strut bar 15 supportings, base 14 is the square shape framed structure, see Fig. 2, front and rear beam 17, two road wheels 13 are respectively installed in 19 bottom, making base can support loop wheel machine moves freely, article two, supporting leg 11 front bottom end are equipped with road wheel, the rear end is fixed with gusset piece 10, this gusset piece 10 is the radial slot of open top, and slideway 12 and horizontal location hole 5 and folding knock hole 7 are arranged on the sidewall, and the external part of base two curb girders 18 has pin-and-hole 9 and horizontal location hole 6 and folding knock hole 16; , by the slideway 12 on the gusset piece 10 and the pin-and-hole 9 of base curb girder external part gusset piece is connected with curb girder with bearing pin 8, constitute the revolution width of cloth and the mobile width of cloth, make that supporting leg 11 can be with respect to curb girder parallel motion and rotation.During work, by the horizontal location hole on gusset piece and the curb girder 5,6, supporting leg and base are fixed on level attitude, make loop wheel machine center of gravity when lifting move forward with spade pin 4; After work is finished, pull up spade pin 4, move supporting leg 11 along the direction of arrow among Fig. 1, then supporting leg is rotated around bearing pin 8 and hold up to the folding position, by shown in Figure 3, supporting leg is fixed by the folding knock hole on gusset piece and the curb girder 7,16 with spade pin 4, the folding position of supporting leg makes the center of gravity of whole crane self drop on the base, is the best with four even load-bearing of road wheel of base bottom.

Claims
