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
The present invention relates to a kind of supporting leg, be meant special vehicle such as comprehensive commander's police car, satellite communication command van, environmental monitoring vehicle, the automobile-used supporting box pulsation-free supporting leg of medical rescue especially.
Background technology
At present, comprehensively command police car generally to run into incident and just can use, carry completely to park for a long time and cause truck spring steel version modification.The satellite communication command van need solve long-term fully loaded parking, and vehicle spring steel plate modification and vehicle be in use because car body rocks the appearances phenomenon of " losing star ", needs in the use that car body is steady, level.Mobile environment monitor is an experimental enviroment, and vehicle rocks can the impact analysis result.The medical rescue car needs to implement operation in case of necessity, and vehicle produces to rock more the possibility that injures life.Vehicle mounting apparatus weight is big, and fully laden is parked for a long time, damage vehicle spring steel plate, tire.Owing to a variety of causes, cause car body wobble effects vehicle result of use, reduce the vehicle life-span during vehicle uses.The supporting leg of existing vehicle has hydraulic principle, the air pressure principle with theory of machines, but no matter be the sort of structure, the lifting position limiting structure of its leg is all very complicated, and service life is short, and is unreliable, even some all is artificially to control its adjustable height, and operation is just pretty troublesome like this; If the inconsistent accident that also occurs easily of the adjustable height of each supporting leg is brought unnecessary trouble in addition.
Summary of the invention
The present invention overcomes the defective that prior art exists, and a kind of rational in infrastructure, the later-model automobile-used supporting leg that can well control the supporting leg heave amplitude is provided.
In order to realize above purpose, the present invention is by the following technical solutions: a kind of automobile-used supporting leg, include feet, realize the lifting operating unit of feet lifting and the limit control of control feet heave amplitude, described lifting operating unit includes the mother lead screw that is fixedly installed on the feet, leading screw and motor with mother lead screw formation screw thread fit, it is characterized in that: described limit control includes two travel switches and and has shifting block and get runner, has between the runner of shifting block and the motor output shaft by gear cluster or chain gear.
By adopting such scheme, we can put in place with the lifting that realizes supporting leg that cooperates of travel switch by shifting block, the control the when lifting that can guarantee each supporting leg like this puts in place, and simple in structure in addition, cost is low.
The further setting of the present invention is: an end end of described leading screw is set with sprocket wheel, described motor output shaft is provided with sprocket wheel, pass through belt-driving between sprocket wheel on the leading screw and the sprocket wheel on the motor output shaft, be set with a miniature gears on the chain wheel end on the described leading screw, this miniature gears is provided with sprocket wheel is concentric, is provided with by the transmission of secondary gear group between described miniature gears and the runner; Described leading screw outer cover is provided with maintainance set and dustproof sliding sleeve, is provided with the rubber skin between the lower curtate of dustproof sliding sleeve and feet, and described maintainance set outer setting has retracing spring, and its sprocket wheel one end that is positioned at of described leading screw is provided with pressure bearing and graphite oilless sintered-metal bearing.
The effect that the present invention further is provided with is: the reasonable integral structure of the said goods, and utilize a motor to realize the lifting of supporting leg and the control that heave amplitude puts in place in addition, can save the cost of product greatly, need not manual operation.
Below in conjunction with accompanying drawing the present invention is described in further detail.
