Abstract
The invention discloses a lift-press lock catch foldable crane and relates to loading machinery, namely, a crane. The crane comprises a wheel, a wheel lift-press lock catch, a horizontal positioning hole B, a foldable positioning hole A and a jack and is characterized in that: moving wheels at the lower end of a base can support the crane to move freely; a support leg is connected with the base through a pin shaft so as to form a revolving pair; the support leg and the base are provided with positioning holes; a bolt passes through the positioning holes on the support leg and the base so as to fix the support leg and the base in a U shape at a horizontal position or the support leg is rotated vertically around the pin shaft and fixed at a folding position with the base; and the wheel is mechanically connected with the wheel lift-press lock catch, so that the wheel is locked in a hoisting process. The crane has the advantages that: due to the adoption of the technical scheme, the novel support leg of the crane can be folded vertically, so that the crane has a greatly reduced floor area, convenient and flexible movement, convenient folding and high adaptability. The wheel is mechanically connected with the wheel lift-press lock catch, so that the wheel is locked in the hoisting process and does not slide when an object is hoisted and hoisting is performed safely.
Description
Technical field
The present invention relates to loading machine---the folding lift-press lock catch foldable crane of loop wheel machine, particularly supporting leg.
Background technology
Loop wheel machine in the market is made up of base, column, jack, cantilever etc., and base is a u shape, and two supporting legs can telescopically be fixed on base U-shaped open end, and 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.
Summary of the invention
In order to overcome the deficiencies in the prior art part, provide a kind of supporting leg to shrink that the back floor area is little, the lift-press lock catch foldable crane of conveniently moving.
Technical scheme: a kind of lift-press lock catch foldable crane comprises wheel, the pressure-lift snap close of wheel, principal post, spade pin, horizontal location hole A, horizontal location hole B, folding knock hole A, bearing pin, pin-and-hole, gusset piece, two supporting legs, slideway, road wheel, base, strut bar, folding knock hole B, front-axle beam, base two curb girders, the back rest, cantilever, jack are formed, and 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 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.The pressure-lift snap close mechanical connection of wheel and wheel makes wheel locking during lifting.
Technique effect: owing to adopt such scheme, this novel support leg can be holded up folding, thereby floor area reduces greatly, and conveniently moving is flexible, and folding also more convenient, and applicability is good.The pressure-lift snap close mechanical connection of wheel and wheel makes wheel locking during lifting, can not slide the safety lifting during lifting article.
Description of drawings
Fig. 1 is that structure master of the present invention looks scheme drawing;
Fig. 2 is a plan structure scheme drawing of the present invention.
The invention will be further described below in conjunction with accompanying drawing and a specific embodiment:
The specific embodiment
With reference to accompanying drawing: 1. wheel, the 2. pressure-lift snap close of wheel, 3. column, 4. spade pin, 5. horizontal location hole A, 6. horizontal location hole B, 7. folding knock hole A, 8. bearing pin, 9. pin-and-hole, 10. gusset piece, 11. two supporting legs, 12. slideways, 13. road wheel, 14. bases, 15. strut bars, 16. folding knock hole B, 17. front-axle beams, 18. bases, two curb girders, 19. the back rest, 20. cantilevers, 21. jacks.
Shown in figure, column 3, cantilever 20, jack 21 constitutes four-bar linkage, column 3 is by base 14 and strut bar 15 supportings, base 14 is the square shape framed structure, see Figure 21, front-axle beam 17, two road wheels 13 are respectively installed in the bottom of the back rest 19, 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 uncovered radial slot of napex, and slideway 12 and horizontal location hole 5 and folding knock hole A7 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 B16; , 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 A5 on gusset piece and the curb girder, horizontal location hole B6, 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, the direction of arrow moves supporting leg 11 among the figure, then supporting leg is rotated around bearing pin 8 and hold up to the folding position, shown in figure, supporting leg is fixed by the folding knock hole A7 on gusset piece and the curb girder, folding knock hole B16 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.Wheel 1 and pressure-lift snap close 2 mechanical connections of wheel make wheel locking during lifting, can not slide the safety lifting during lifting article.
