Description
Technical field
The utility model relates to lorry-mounted crane technology, be specifically related to a kind of can 90 degree upset lorry-mounted crane leg structures.
Background technology
Lorry-mounted crane refers to and is arranged on car chassis, and many actions elevator machinery of vertical-lift and horizontal carrying heavy goods, also known as truck-mounted crane, belongs to material carrying machine within the specific limits.The functional requirement of domestic every profession and trade to hoisting crane is more and more higher, requires higher especially to the lorry-mounted crane having lifting and transportation function concurrently.
The support oil cylinder composition majority of existing collapsible lorry-mounted crane seat movable leg is designed to fixed type, but some support oil cylinder composition is designed to movablely need use manpower manual overturning, because the deadweight of support oil cylinder composition is heavier, manpower upset need consume a large amount of manpower and handle more dangerous, easily causes the damage of personnel and equipment.
Summary of the invention
For overcoming the deficiencies in the prior art and Problems existing, the utility model provide one can actv. save human resources, increase work efficiency, compact conformation, reduce the space hold of lorry-mounted crane can 90 degree overturn lorry-mounted crane leg structures.
The utility model is achieved through the following technical solutions:
Can the lorry-mounted crane leg structures of 90 degree of upsets, comprise movable leg and be located at the supporting leg for movable support leg of movable leg end, described supporting leg comprises support oil cylinder, and support oil cylinder transmission shaft end is provided with pin-and-hole; Described movable leg end is provided with adapter plate, and adapter plate is provided with the jack corresponding with pin-and-hole, by insert-pull pin, pin-and-hole is aimed at grafting with jack and fixes.
Described support oil cylinder outer wall is fixed with overturning oil cylinder, and overturning oil cylinder transmission shaft end is connected with movable leg, is rotated around centre hole by overturning oil cylinder telescopic drive support oil cylinder.
Described jack comprises centre hole, packing up knock hole and launching for fixed supporting leg oil cylinder when packing up for fixed supporting leg oil cylinder time expansion knock hole.
Described pin-and-hole has two.
A described pin-and-hole and central aperture are fixed, and another pin-and-hole is aimed at fixing with packing up knock hole or launch knock hole.
Provided by the utility model can 90 degree upset lorry-mounted crane leg structures, stretched by overturning oil cylinder, supporting leg can be turned over and turn 90 degrees, thus effectively save manpower, improve the safety of operating personal and make lorry-mounted crane design more compact conformation, reducing the space hold of lorry-mounted crane.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Number in the figure: 1-movable leg, 2-supporting leg, 3-support oil cylinder, 4-pin-and-hole, 5-overturning oil cylinder, 6-centre hole, 7-packs up knock hole, and 8-launches knock hole, 9-adapter plate, 10-journal stirrup.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model is described in further detail.It should be pointed out that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of can the lorry-mounted crane leg structures of 90 degree of upsets, comprise movable leg 1 and be located at the supporting leg 2 for movable support leg 1 of movable leg 1 end, described supporting leg 2 comprises support oil cylinder 3, and support oil cylinder 3 transmission shaft end is provided with pin-and-hole 4; Described movable leg 1 end is provided with adapter plate 9, and adapter plate 9 is provided with the jack corresponding with pin-and-hole 4, by insert-pull pin, pin-and-hole 4 is aimed at grafting with jack and fixes.
Described jack comprises centre hole 6, packing up knock hole 7 and launching for fixed supporting leg oil cylinder 3 when packing up for fixed supporting leg oil cylinder 3 time expansion knock hole 8.Described pin-and-hole 4 has two.A described pin-and-hole 4 is aimed at fixing with centre hole 6, another pin-and-hole is aimed at and fixed with packing up knock hole 7 or launch knock hole 8.
Described support oil cylinder 3 outer wall is fixed with overturning oil cylinder 5, overturning oil cylinder 5 transmission shaft end is connected with movable leg 1, rotated around centre hole 6 by overturning oil cylinder 5 telescopic drive support oil cylinder 3, in the present embodiment, movable leg 1 is provided with the journal stirrup 10 with certain length, makes centre hole, overturning oil cylinder 5 fixed end and transmission shaft end three points form connecting rod mechanism.Lorry-mounted crane in the process of walking, needs supporting leg 2 to pack up, is just shunk by overturning oil cylinder 5, by supporting leg 2 pull-up, supporting leg 2 centrally hole turn to and packs up knock hole 7 and aim at another pin-and-hole, enters to pack up in knock hole 7 and this pin-and-hole by insert-pull pin grafting, just can fixed supporting leg 2; Lorry-mounted crane is when handling weight, need weight supporting leg 2 being put down carrying movable leg 1, just the insert-pull pin being inserted in and packing up in knock hole 7 is extracted, overturning oil cylinder 5 stretches, put down by supporting leg 2, supporting leg 2 centrally hole turn to and launches knock hole 8 and aims at another pin-and-hole, insert-pull pin grafting is in progress and opens knock hole 8 with in this pin-and-hole, now supporting leg 2 and plane perpendicular, just can carry the weight of movable leg 1.
