Abstract
A vehicle-mounted hanging ladder comprises a ladder frame and a plurality of pedals, wherein the ladder frame comprises four struts, each pedal which is arranged on four corners in the longitudinal direction is movably hinged on the four struts through rivets, and the pedals and the four struts are formed into a parallel link mechanism. The upper portions of a front left strut and a rear left strut are respectively hinged with a hanger through rivets, and the upper portions of the front right strut and the rear right strut are respectively connected with a screw through screw sleeves. Grooves which are arranged on the hangers are movably connected with screw rods. The bottoms of the four struts are respectively provided with a ladder frame support foot. The ladder frame support feet and the struts are in universal joint structures. The ladder frame of the folding type vehicle-mounted hanging ladder can be folded and self-locked into an inclined ladder, and the vehicle-mounted hanging ladder is in hanging connection with a main car through the hangers, so that operators can safely get on/off a vehicle. The vehicle-mounted hanging ladder is designed according to the link mechanism principle, is simple in structure, low in cost, convenient in operation, and can be used in an oil tank truck. Users can change the angle of the hanging ladder when hanging the hanging ladder on a vehicle, and accordingly the hanging ladder is adapted to bumpy roads. The universal joint structures are adopted between the ladder frame support feet and the struts, accordingly the support can be adjusted automatically, and the support stability is realized.
Description
Technical field
The utility model relates to a kind of working stand, particularly relates to a kind of collapsible vehicle-mounted hanging ladder of being convenient to steadily lay.
Background technology
Traditional vehicle-mounted hanging ladder that jar class transport trolley is settled is many to be fixed with car load, and personnel can only get on or off the bus from a position, through regular meeting because of the improper staff of causing in the automobile stop position inconvenience of getting on or off the bus.In addition, traditional hanging ladder mostly is the plane formula structure, can only select flat road surface to support, if the bottom unfairness, causes hanging ladder to support unstable easily and tumbles.
The utility model content
The purpose of this utility model is the defective that overcomes above-mentioned traditional hanging ladder, provides a kind ofly can stablize placement on unfairness ground, is fit to vehicle delivery and lays the movable vehicle-mounted hanging ladder that makes things convenient for the staff to get on or off the bus.
The purpose of this utility model can realize.Vehicle-mounted hanging ladder of the present utility model comprises ladder and several pedals, wherein said ladder comprises preceding left pillar, preceding right pillar, the right pillar of left pillar in back and back, each described pedal is left pillar before vertical four jiaos of places are movably articulated in by rivet all, preceding right pillar, the left pillar in back, on the right pillar in back, some pedals and preceding left pillar, preceding right pillar, the left pillar in back, the right pillar in back constitutes parallel linkage, left pillar and left pillar top, back respectively are hinged with a hook by rivet before described, right pillar respectively is connected a screw with right pillar top, back by swivel nut before described, described hook is provided with groove, and the polished rod of described groove and described screw survives the running-fit pair.
Vehicle-mounted hanging ladder of the present utility model, wherein said preceding left pillar, preceding right pillar, the left pillar in back, a right column bottom, back respectively are provided with the ladder heel brace, and described ladder heel brace becomes gimbal structure respectively with described preceding left pillar, preceding right pillar, the left pillar in back, the right pillar in back.
Vehicle-mounted hanging ladder of the present utility model can be fixed on the truck tanker with car delivery, and ladder is collapsible, becomes inclined ladder by the fixed plate self-locking; Utilize hook to be overlapped on the car body outward flange, articulate, get on or off the bus to the handled easily personal security with main car.The utility model is according to the connecting rod mechanism principle design, and ladder changes angle, is articulated in applicable uneven ground-surface expansion on the vehicle; Adopt gimbal structure between ladder heel brace and the pillar, can support with ground out-of-flat automatic compensation, thereby reach collapsible vehicle-mounted hanging ladder supporting ﹠ stablizing on roughness pavement.
Below in conjunction with accompanying drawing vehicle-mounted hanging ladder of the present utility model is described further.
