Abstract
The utility model relates to a fast-retracting vehicle folding ladder device, which is a part of the special vehicle or the moveable working platform. The fast-retracting vehicle folding ladder is divided into three sections, which are connected together in series by the shaft and form a bending and folding mechanism. After being provided with a hydraulic cylinder, an operating mechanism of the wrist-type is constituted. The electric circuit controls the operation of the hydraulic valve to complete the operations such as rotation, folding and closing, elevating and locking, and other operations. The utility model has the advantages of improving the using efficiency, prolonging the service life, and raising up the product grade.
Description
Affiliated technical field
The utility model relates to a kind of vehicle folding ladder device of quickly retracting.Be parts in special-use vehicle or the mobile working platform.
Background technology
At present, general automobile-used ladder all is plug-in or the extraction formula, and basic all uses are manually in place.Method is original, easily comes off, shortcoming such as poor stability, service efficiency are low.Because processing is simple, operating needs is not high, and at special vehicle, remoulded car is not used not variation till today always on the mobile platform.Along with the upgrading of operating needs, but to reach a higher class, often only change material and do not change structure.Automobile-used ladder produces collision vibrations and noise unfavorable service life when moving with car, also be unfavorable for city environmental protection.
Summary of the invention
In order to overcome the deficiency of existing automobile-used ladder, the utility model provides a kind of novel hydraulic pressure vehicle folding ladder device.And solved automatic deploying and retracting.Put in place and function such as automatically lock.
The technical scheme that its technical matters that solves the utility model adopts is: the automobile-used ladder of quickly retracting is divided into three sections, is connected into a flexible mechanism that closes up after connecting with axle, mix hydraulic ram again, form a carpal actuating mechanism of likeness in form.Action by circuit modulated pressure valve.Finish rotation, folding closing up, action such as lift.
The beneficial effects of the utility model are, can automatic deploying and retractings, changed original hand labour, and reduce the collision between the parts, eliminated noise, increased work life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a profile mechanism map of the present utility model.
Among the figure 1, go up ladder 2, frame 3, middle terraced 4, descending stair
Specific implementation method
In the embodiment shown in fig. 1, finish by electrical equipment control hydraulic ram pushing mechanism entirely.During contraction, first descending stair (4) rotates to and closes up around the axle of middle ladder (3), and the axle around last ladder (1) rotates to end position and locking again.Move on the contrary according to last program when emitting.
Claims (1)
1, a kind of vehicle folding ladder device of quickly retracting is parts in special-use vehicle or the mobile working platform, it is characterized in that promoting a carpal actuating mechanism of likeness in form by the electrical equipment control hydraulic ram finishes.
