Embodiment Construction

[0040] Since the climbing ladder is configured by the original factory and its position is relatively fixed, the distance between the two climbing ladders used to carry the two rows of wheels of the vehicle to be transported is fixed, and the width cannot be adjusted to meet the needs of vehicles with different wheelbases.

[0041] The invention provides a hydraulic climbing ladder, which includes a slide block, a horizontal oil cylinder and two ladders. At least one transverse chute is arranged at the rear end of the car body, and the slide block is slidably embedded in the chute; the horizontal oil cylinder is arranged horizontally, and the horizontal The two ends of the oil cylinder are respectively connected with the car body and the slider and are used to pull the slider to slide in the chute; one end of at least one ladder is hinged to the slider, and a rotating oil cylinder is arranged between the slider and the ladder, and the two ends of the rotating oil cylinder are re...

Abstract

The invention provides a hydraulic climbing ladder, which belongs to the field of rear climbing ladders of semi-trailer low-bed vehicles, and includes a slider, a horizontal oil cylinder and two climbing ladders. The rear end of the car body is provided with at least one transverse chute. In the groove; the horizontal oil cylinder is arranged horizontally, and the two ends of the horizontal oil cylinder are respectively connected with the car body and the slider and are used to pull the slider to slide in the chute; one end of at least one ladder is hinged with the slider, and there is a A rotary oil cylinder, the two ends of the rotary oil cylinder are respectively hinged with the slide block and one side of the climbing ladder. By controlling the elongation of the horizontal cylinder, the slider can slide horizontally in the chute, and the slider drives the ladder to move, thereby making the distance between the two ladders larger or smaller, which can be automatically adjusted according to the needs of different transportation equipment The distance between the two climbing ladders is suitable for the use of various types of vehicles with large wheelbase changes.

Description

technical field [0001] The invention relates to the field of rear ladders for low-bed semi-trailers, in particular to hydraulic ladders. Background technique [0002] Low-bed semi-trailers are usually used to transport heavy-duty vehicles (such as tractors, buses, special-purpose vehicles, etc.), rail vehicles, mining machines, forestry machines, road construction machinery, engineering machinery, agricultural machinery and other heavy-duty goods. When it is necessary to use the climbing ladder to make the vehicle to be transported climb the slope and reach the car body. [0003] Since the climbing ladder is configured by the original factory and its position is relatively fixed, the distance between the two climbing ladders used to carry the two rows of wheels of the vehicle to be transported is fixed, and the width cannot be adjusted to meet the needs of vehicles with different wheelbases. Contents of the invention [0004] The invention provides a hydraulic climbing la...
