Description
Technical field
The utility model relates to semitrailer technical fields, and in particular to a kind of semitrailer automatic lifting stand.
Background technique
Currently, being used to transport the vehicle of bulk goods in the place such as steel mill, harbour is mostly semi-trailer tipping vehicle.The axle position of semitrailer
Behind vehicle frame center, front end is provided with the hookup being connected with tractor, to realize the traction to semitrailer.When
When semitrailer is not connected with tractor, the support to semitrailer front end is realized by support device, to guarantee that semitrailer is in
Horizontality.
When tractor connects upper trailer operation, needs to rise support device, mostly use hand-rail type at present, it is time-consuming to take
Power, and have the place of protrusion on the bad ground of road conditions, even if entire support device increases, supporting leg still straight down, most
Bottom end is still relatively close from the ground, and supporting leg is easy protrusion collision.
Utility model content
In order to overcome drawbacks described above, the utility model provides a kind of semitrailer automatic lifting stand, is installed on vehicle
Front edge of board, including two hydraulic cylinders, the cylinder body of two hydraulic cylinders are individually fixed in the both sides of sweep upper surface, and two described hydraulic
The piston rod of cylinder straight down and stretches out outside sweep, and connecting plate, the piston of two hydraulic cylinders are equipped with below the sweep
Boom end is respectively fixedly connected with the both sides at the top of connecting plate, and the connecting plate bottom both sides are hinged with supporting leg, the connecting plate bottom
It is equipped with fixed block at portion center, is respectively provided with an electric telescopic rod between two supporting legs at left and right sides of the fixed block, it is electronic to stretch
Contracting bar both ends are hinged with fixed block and supporting leg respectively.
Further, the connecting plate and two supporting leg junctions are respectively arranged in the front and the rear with a block baffle, corresponding two block baffle
Between it is hinged by pin shaft and supporting leg, corresponding two block baffle far between the both sides of fixed block equipped with one piece of limit plate.
The beneficial effects of the utility model are: the utility model structure is simple, it can be achieved that support device automatic lifting, and
When support device increases, supporting leg can be packed up to center, increase the spacing of supporting leg bottom and ground, avoid supporting leg and road
The bad ground of condition collides.

Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical
Novel protected range.
It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
A kind of semitrailer automatic lifting stand as depicted in figs. 1 and 2 is installed on 1 front end of sweep, including two liquid
Cylinder pressure 2, the cylinder body of two hydraulic cylinders 2 are individually fixed in the both sides of 1 upper surface of sweep, and the piston rod 3 of two hydraulic cylinders 2 is vertical
It downwards and stretches out outside sweep 1, connecting plate 4 is equipped with below sweep 1,3 end of piston rod of two hydraulic cylinders 2 is fixedly connected on respectively
4 top both sides of connecting plate, 4 bottom both sides of connecting plate are hinged with supporting leg 5, and 4 bottom center of connecting plate is equipped with fixed block 10, fixed
Be respectively provided with an electric telescopic rod 9 between the left and right sides of block 10 and two supporting legs 5,9 both ends of electric telescopic rod respectively with fixed block 10
It is hinged with supporting leg 5.
Connecting plate 4 and two 5 junctions of supporting leg are respectively arranged in the front and the rear with a block baffle 8, pass through pin shaft between corresponding two block baffle 8
7 is hinged with supporting leg 5, and one piece of limit plate 6 is equipped between corresponding both sides of two block baffle 8 far from fixed block 10.
When semitrailer front end needs to support, two electric telescopic rods 9 extend, and supporting leg 5 stretches out, until supporting leg 5 is in vertical
The piston rod 3 of state, latter two right hydraulic cylinder 2 stretches out simultaneously, so that connecting plate 4 declines with supporting leg 5, until 5 bottom end of supporting leg
With ground face contact.It is not in that supporting leg 5 is greater than with 4 angle of connecting plate when electric telescopic rod 9 extends because of the setting of limit plate 6
90 degree of the case where.When semitrailer front end does not need support, the piston rod 3 of hydraulic cylinder 2 is withdrawn, so that connecting plate 4 is with supporting leg 5
It increases, while electric telescopic rod 9 is shunk, and supporting leg 5 is withdrawn, the supporting leg 5 when road conditions are bad is avoided to collide with ground.
The limitation that the technical solution of the utility model is not limited to the above specific embodiments, all skills according to the present utility model
The technology deformation that art scheme is made, each falls within the protection scope of the utility model.
