Abstract
A kind of turning lorry-mounted crane leg structure, comprise movable leg and the supporting leg for movable support leg being located at movable leg end, described movable leg end is provided with hinge hole, supporting leg is installed with the jointed shaft mated with hinge hole, and supporting leg and movable leg are by hinge hole and jointed shaft chain connection; Described movable leg end is provided with overturning oil cylinder, drives jointed shaft to rotate thus drive supporting leg upset by overturning oil cylinder.Turning lorry-mounted crane leg structure provided by the utility model, stretched by overturning oil cylinder, band carry-over bar stretches, rack and pinion engages, therefore pinion rotation drive jointed shaft to rotate, thus realize supporting leg upset, solve the problem due to wheel can be bumped against time distance that lorry two wheels of various criterion are different causes the leg alive of lorry-mounted crane to stretch, and this structure more seems that project organization is compact when being applied on the lorry-mounted crane of medium-and-large-sized tonnage, reduces the space hold of lorry-mounted crane.
Description
Technical field
The utility model relates to lorry-mounted crane technology, is specifically related to a kind of turning lorry-mounted crane leg structure.
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.Along with expanding economy and social higher demand, medium-and-large-sized tonnage lorry-mounted crane is more and more applied to industry-by-industry.
Due to the Automobile manufacturing standard between country variant, car chassis design is caused to be had nothing in common with each other, distance between wheel is not quite similar, time this situation causes medium-and-large-sized tonnage lorry-mounted crane to be arranged on car chassis, time leg section of living may be installed or leg of living stretches out, supporting leg can encounter wheel.
Summary of the invention
For overcoming the deficiencies in the prior art and Problems existing, the utility model provide a kind of can efficient solution determine the car chassis of country variant and wheel tracks from produced installation question, project organization is compact, the turnover lorry-mounted crane leg structure of the space hold that reduces lorry-mounted crane.
The utility model is achieved through the following technical solutions:
A kind of turnover lorry-mounted crane leg structure, comprise movable leg and the supporting leg for movable support leg being located at movable leg end, described movable leg end is provided with hinge hole, supporting leg is installed with the jointed shaft mated with hinge hole, and supporting leg and movable leg are by hinge hole and jointed shaft chain connection; Described movable leg end is provided with overturning oil cylinder, drives jointed shaft to rotate thus drive supporting leg upset by overturning oil cylinder.
Described jointed shaft is provided with the gear concentric with jointed shaft.
Described overturning oil cylinder transmission shaft end is provided with the tooth bar with the gears meshing on jointed shaft.
Described supporting leg is provided with a fixed mount, and described jointed shaft is fixed on fixed mount.
Described fixed mount is also provided with knock hole when to pack up for fixed supporting leg or launch, described movable leg is provided with the pin hole corresponding with knock hole when supporting leg is packed up or launch, the state packed up by latch fixed supporting leg or launched.
Turning lorry-mounted crane leg structure provided by the utility model, stretched by overturning oil cylinder, band carry-over bar stretches, rack and pinion engages, therefore pinion rotation drive jointed shaft to rotate, thus realize supporting leg upset, solve the problem due to wheel can be bumped against time distance that lorry two wheels of various criterion are different causes the leg alive of lorry-mounted crane to stretch, and this structure more seems that project organization is compact when being applied on the lorry-mounted crane of medium-and-large-sized tonnage, reduces the space hold of lorry-mounted crane.
Accompanying drawing explanation
Structural representation when Fig. 1 is the expansion of the utility model supporting leg;
Fig. 2 is the utility model supporting leg structural representation when packing up;
Fig. 3 is the structural representation of the utility model when being installed on the lorry-mounted crane of medium-and-large-sized tonnage.
Number in the figure: 1-movable leg, 2-supporting leg, 3-fixed mount, 4-jointed shaft, 5-gear, 6-overturning oil cylinder, 7-tooth bar.
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 illustrated in the accompanying drawings from 1 to 3, a kind of turning lorry-mounted crane leg structure, comprise movable leg 1 and the supporting leg 2 for movable support leg 1 being located at movable leg 1 end, the coupling end that supporting leg 2 is connected with movable leg 1 is provided with a fixed mount 3, and jointed shaft 4 is fixed on fixed mount 3.Movable leg 1 end is provided with hinge hole, supporting leg 2 is installed with the jointed shaft 4 mated with hinge hole, and supporting leg 2 and movable leg 1 are by hinge hole and jointed shaft 4 chain connection; Movable leg 1 end is provided with overturning oil cylinder 6, drives jointed shaft 4 to rotate thus drive supporting leg 2 to overturn by overturning oil cylinder 6.
Fixed mount 3 is also provided with knock hole when packing up for fixed supporting leg 2 or launch, movable leg 1 is provided with the pin hole corresponding with knock hole when supporting leg 2 is packed up or launched, the state packed up by latch fixed supporting leg or launched.
Jointed shaft 4 is provided with the gear 5 concentric with jointed shaft 4.Described overturning oil cylinder 6 transmission shaft end is provided with the tooth bar 7 engaged with the gear 5 on jointed shaft 4.Overturning oil cylinder 6 stretches, and tooth bar 7 driven gear rotates, thus realizes supporting leg 2 and overturn.When overturning oil cylinder 6 stretches, tooth bar 7 driven gear 5 rotates, and supporting leg 2 launches and plane perpendicular, and now corresponding knock hole and pin hole are fixed by latch, and supporting leg 2 just realizes launching stationary state; When overturning oil cylinder 6 shrinks, tooth bar 7 driven gear 5 rotates, and supporting leg 2 is packed up, and supporting leg when packing up is 180 degree with supporting leg when launching, and now corresponding knock hole and pin hole are fixed by latch, and supporting leg 2 just realizes packing up stationary state.As shown in Figure 3, when the utility model compact design is installed on the lorry-mounted crane of medium-and-large-sized tonnage, more save the space hold of hoisting crane.
