Embodiment Construction

[0009] Refer to the accompanying drawings: 1. Wheel, 2. Wheel flip-type lock, 3. Column, 4. Pin, 5. Horizontal positioning hole A, 6. Horizontal positioning hole B, 7. Folding positioning hole A, 8. Pin Shaft, 9. Pin hole, 10. Connecting plate, 11. Two legs, 12. Slideway, 13. Traveling wheel, 14. Base, 15. Support rod, 16. Folding positioning hole B, 17. Front beam, 18. Beams on both sides of the base, 19. Back beam, 20. Cantilever, 21. Jack.

[0010] As shown in the figure, the column 3, the cantilever 20, and the jack 21 constitute a four-bar linkage mechanism, the column 3 is supported by the base 14 and the support rod 15, and the base 14 is a square frame structure, as shown in Figure 21, the bottom of the front beam 17 and the rear beam 19 Two walking wheels 13 are respectively installed so that the base can support the crane to move freely. The front and bottom of the two supporting legs 11 are equipped with walking wheels, and the rear end is fixed with a connecting pl...

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 [0001] The invention relates to a loading machine-a crane, in particular to a lift-and-press lock folding crane with foldable outriggers. Background technique [0002] The cranes currently on the market are composed of a base, a column, a jack, and a cantilever. The base is U-shaped, and the two legs can be telescopically fixed on the U-shaped opening of the base. wheel load-bearing and mobile crane. Although the outriggers of this crane can be contracted, due to the limited length of the contraction, the floor space is relatively large, and it is relatively inconvenient to move. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, a lift-and-lock folding crane with a small footprint and convenient movement is provided after the outriggers are retracted. [0004] Technical solution: A lifting lock folding crane, including wheels, wheel lifting locks, main columns, pins, horizontal positioning holes A, horizontal posit...
