Description
Technical field
A kind of liftable caravan trailer is the utility model is related to, specifically a kind of caravan chassis wheel of pulling
Caravan chassis is pulled in cable type elevating mechanism and lifting.
Background technology
Caravan chassis should have good stability, ensure caravan security and comfortableness.Prior art is used in room
The structure of several supporting legs that can be stretched is installed on the polycrystalline substance of car, when needing to fix caravan, stretches out supporting leg,
Against on the ground, the stability of caravan is improved to a certain extent.But because supporting leg is usually slim-lined construction, in strong wind etc.
Under mal-condition, caravan still has the risk toppled over., can be by the chassis design of caravan in order to further improve the stability of caravan
Into liftable structure, the center of gravity of caravan is reduced, can also improve the stability of caravan.But prior art can only finite reduction caravan
Chassis height, chassis can not still be implemented on the ground completely.
Utility model content
The utility model provides a kind of cable type elevating mechanism for pulling caravan chassis wheel and caravan chassis is pulled in lifting,
Technical problem on the ground can directly be implemented by solving caravan chassis, improve the stability and security on caravan chassis.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
A kind of cable type elevating mechanism for pulling caravan chassis wheel, including the wheel group for support chassis, its feature
It is, the wheel group includes rotating shaft, two connecting levers and two wheels being transversely mounted on chassis, and two connecting levers are fixed respectively
At rotating shaft both ends, two wheels are separately mounted on the free end of connecting lever, and a pivoted arm, pivoted arm and rope are at least installed in rotating shaft
Mechanism corresponds, and rope mechanism is fixed on chassis, is connected between rope mechanism and corresponding pivoted arm with rope, make crosser
Structure winding pulled by cable pivoted arm rotates.
Compared to the prior art, the beneficial effects of the utility model are to improve the stability on caravan chassis, are specifically restricted
Rope mechanism makes axis of rotation, and rotating shaft drives the connecting lever on both sides to rotate, so under the drive of connecting lever, the wheel of connecting lever free end
Just axis around the shaft is rotated, and wheel is relatively moved with respect to chassis, and wheel can be moved to above chassis, make chassis straight
Connect and implement on the ground, improve chassis and contact area of ground, significantly improve the stability of caravan.
The utility model also does following improvement：
In the rotating shaft install two pivoted arms, two pivoted arms respectively close to chassis both sides wheel, in addition to two and turn
The one-to-one guiding mechanism of arm, guiding mechanism are fixed on chassis, and leading block is installed on guiding mechanism, and the end of rope is consolidated
It is scheduled on guiding mechanism, and is supported on the drawing end of leading block and pivoted arm.
At least one set of wheel group in addition is also installed, the pivoted arm in the rotating shaft of adjacent wheels group is connected with transmission arm on chassis.
The utility model also provides a kind of lift and pulls caravan chassis, including the cable type for hanging caravan chassis wheel
Elevating mechanism.

Transmission arm, 12 pivoted arms, 13 wheels, 14 rotating shafts.
Embodiment
The utility model is elaborated with reference to the accompanying drawings and examples.
It should be noted that having symmetrical structure in view of the utility model, accompanying drawing is attached most importance to the side of symmetrical structure
Mark, is illustrated mainly in combination with the part of mark below.
With reference to Fig. 1 and Fig. 2, the wheel group being made up of rotating shaft 8 and two wheels 6, rotating shaft 8 is arranged on the chassis of caravan,
Such as Fig. 1, chassis 9 is represented with straight line, for explaining the relative position on chassis and wheel.Rotating shaft 8 is arranged on chassis, is such as schemed
2, bearing is installed respectively in the both sides of rotating shaft 8, such as the bearing 6 in left side, bearing is fixed on chassis.
In order that forming eccentric structure between wheel and rotating shaft, such as Fig. 1 and Fig. 2, connecting lever is fixed at the both ends of rotating shaft 8, such as
The connecting lever 7 in left side.The free end installing wheel 6 of connecting lever 7.The so axis rotation of the rotational band motor car wheel 6 of rotating shaft 8 around the shaft, makes
Relative movement is formed between wheel 6 and chassis.Wheel 6 supports on the ground, when the change of the distance between wheel and chassis is small, bottom
Relatively face has a downward action to disk 9, declines chassis.On the contrary, when rotating shaft 8 rotates backward, between wheel and chassis
Distance become big, relatively face has a upward action on chassis, raises chassis.In order to more fully understand This move mistake
Journey, can be the state that chassis rises with reference to Fig. 1 and Fig. 3, Fig. 1, Fig. 3 is the state that chassis declines.
Such as Fig. 1 and Fig. 2, in order to realize axis of rotation, in rotating shaft both sides installation pivoted arm 5 (such as Fig. 2), pivoted arm 5 and rotating shaft 8 are firm
Property connection, pivoted arm 5 connect with a rope mechanism, such as Fig. 1, and rope mechanism includes the rope pulley 2 and handle on chassis
1, rope pulley 2 is rotated using handle 1, rope 3 is pulled pivoted arm 5 and rotates, rotate rotating shaft 8, rotating shaft 8 is counterclockwise with motor car wheel 6
Direction rotates around the axis, and chassis 9 is raised with respect to ground, on the contrary, rotating backward rope pulley 2, rope 3 is progressively discharged to pivoted arm
5 drawing, in the presence of the self gravitation of chassis, wheel 6 rotates clockwise with respect to rotating shaft 8, makes chassis 9 with respect to subsurface
Drop.
In order to preferably adjust the angle of pulled by cable pivoted arm, fixed guide mechanism, such as Fig. 1, Guiding machine are gone back on chassis
Leading block is installed, the head end of rope 3 is connected on winding wheel 2, and the end of rope 3 is connected on guiding mechanism 4, rope 3 on structure 4
Also it is supported on the drawing end of leading block and pivoted arm 5, such structure similar pulley group, can not only changes guiding mechanism
Position, adjustment pivoted arm drawing angle, also rotates winding wheel 2 more laborsaving.
In view of the stability on caravan chassis, two groups of wheel groups can be mounted side by side, also further increase the load on caravan chassis
Lotus ability, such as Fig. 4, on the basis of original wheel group, increase and formed in addition by 14, two wheels 13 of rotating shaft and two connecting levers
One wheel group.Connected between pivoted arm 12 and pivoted arm 5 in the wheel group with transmission arm 11, so when pivoted arm 5 rotates, simultaneously
Drive pivoted arm 12 to rotate, rotate the rotating shaft 14 of the roller group at the place of pivoted arm 12, realize wheel 13 and the chassis in the wheel group
Relative movement, so make four wheel synchronization actions, reach the purpose of the stable lifting in chassis.
