Problems solved by technology

Due to various reasons during the use of the vehicle, the shaking of the vehicle body will affect the use of the vehicle and reduce the life of the vehicle
The supporting legs of existing vehicles have hydraulic principles, pneumatic principles and mechanical principles, but no matter what kind of structure, the lifting limit structure of the legs is very complicated, the service life is short, unreliable, and some are even controlled by humans Its lifting height, so the operation is very troublesome; in addition, if the lifting height of each support leg is inconsistent, it is easy to cause accidents and bring unnecessary troubles

Embodiment Construction

[0012] like figure 1 , figure 2 and image 3 As shown, a supporting leg for a vehicle includes a supporting foot 1, a lifting operation mechanism 2 for realizing the lifting of the supporting foot and a limit control device 3 for controlling the lifting range of the supporting foot. The screw nut 21 on the supporting foot forms a threaded screw 22 and a motor 23 with the screw nut 21. The outer cover of the screw 22 is provided with a retaining sleeve and a dust-proof sliding sleeve, and the dust-proof sliding sleeve and the supporting foot Rubber skins are arranged between the lower parts of the lower parts, and a return spring is arranged on the outside of the retaining sleeve. A pressure bearing and an oil-impregnated bearing are arranged at one end of the sprocket of the screw 22. It is also available above, and we will not describe it in detail in the embodiment of the present invention. In the embodiment of the present invention, the limit control device 3 includes tw...

Abstract

The invention relates to a supporting leg, in particular to a supporting leg for stably supporting box bodies of special vehicles such as an integrated command police vehicle, a satellite communication command vehicle, an environment monitoring vehicle and a medical assistance vehicle. The technical scheme is that: the supporting leg for the vehicles comprises a supporting foot, a lifting operating mechanism for lifting the supporting foot, and a limit control mechanism for controlling the lifting amplitude of the supporting foot, wherein the lifting operating mechanism comprises a screw rod nut fixedly arranged on the supporting foot, a screw rod in threaded fit with the screw rod nut, and a motor. The supporting leg is characterized in that: the limit control device comprises two stroke switches and a rotating wheel with a shifting block; and the rotating wheel with the shifting block is in transmission connection with an output shaft of the motor through a gear set or a chain. Through the scheme, the invention overcomes the defects of the prior art, and provides a novel supporting leg for the vehicles, which has a reasonable structure and well controlled lifting amplitude.

Description

technical field [0001] The invention relates to a support leg, in particular to a stable support leg for special vehicles such as comprehensive command police vehicles, satellite communication command vehicles, environmental monitoring vehicles, and medical rescue vehicles. Background technique [0002] At present, comprehensive command police vehicles are generally used only in case of incidents, and long-term full-load parking will cause the deformation of the spring steel version of the vehicle. The satellite communication command vehicle needs to solve the problem of long-term full-load parking, the deformation of the spring steel plate of the vehicle, and the phenomenon of "lost star" due to the shaking of the vehicle body during use. The vehicle body needs to be stable and level during use. The environmental testing vehicle is a test environment, and the shaking of the vehicle will affect the analysis results. Medical ambulance vehicles need to perform surgery if nece...
