Abstract
The invention discloses a hydraulic supporting cat ladder, and belongs to the technical field of engineering vehicles. A main cat ladder assembly and a hydraulic cylinder are mounted eccentrically; one end of the main cat ladder assembly is fixedly arranged on a cat ladder mounting supporting base; the hydraulic cylinder is arranged on the hydraulic cylinder mounting base; the main cat ladder assembly is provided with a numerical-control detecting device; the numerical-control detecting device is provided with a detecting head; the ejection distance of a piston rod head of the hydraulic cylinder is maximum when a spreading cat ladder assembly is folded completely and is minimum when the spreading cat ladder assembly is unfolded completely; the piston rod head of the hydraulic cylinder is in contact with the detecting head no matter when the ejection distance of the piston rod head of the hydraulic cylinder is maximum or minimum; and starting and stopping of the hydraulic cylinder are controlled precisely by the numerical-control detecting device through the detecting head. The hydraulic supporting cat ladder has the advantages that the main cat ladder assembly and the spreading cat ladder assembly are driven to be folded and unfolded through the hydraulic cylinder, whether a hydraulic supporting cat ladder is folded or unfolded in place or not can be detected precisely through the numerical-control detecting device, starting and stopping of the hydraulic cylinder can be controlled accurately, operation efficiency is improved, and labor intensity of workers is reduced.
Description
Technical field
The present invention relates to engineering truck technical field, be specially a kind of hydraulic pressure support cat ladder.
Background technology
Along with transport service market competition is growing more intense, the kind of trailer is also segmented day by day, one of them vital classification is exactly the flat-bed trailer of professional traffic engineering machinery, the engineering machinery that conveniently hauled weight and volume are all larger, all cat ladder is provided with at the afterbody on chassis, all need workman's manual operation in the process of common cat ladder lifting, be limited to the integral structure of cat ladder, cat ladder length can not be increased too much.Therefore flat-bed trailer of the prior art in use also exists operator's labour intensity greatly, and is attended by certain danger, the short and small shortcoming causing the angle of climbing being difficult to reach engineering machinery of cat ladder.
Engineering low flat bed semi trailer because of by height of car restriction and some special engineered cars upper and lower cat ladder angle requirement less time, cat ladder changes by the low flat car of some engineerings makes hydraulic lift folding type, but when cat ladder is put into certain position, upper joint cat ladder can not freely stretch to be opened, also need to use artificial external force tractive or install separately one group and strut oil cylinder mechanism and can stretch, cat ladder in use simultaneously, effectively can not control it folding and launch whether to put in place, not only complicated operation but also dangerous.
Summary of the invention
The present invention for the technical problem that solves for providing a kind of hydraulic pressure support cat ladder, it completes the folding and expansion of main cat ladder assembly and spreading cat ladder assembly by Driven by Hydraulic Cylinder, and by the numerical control detection device arranged can accurately detect hydraulic pressure support cat ladder whether folding and expansion put in place, can the start and stop of more accurate hydraulic control cylinder.
Technical solution problem of the present invention adopts following technical scheme:
The Foldable hydraulic cat ladder that upper joint cat ladder can stretch automatically along with the decentralization process of cat ladder.
A kind of hydraulic pressure support cat ladder is provided, it mainly comprises main cat ladder assembly, spreading cat ladder assembly, hydraulic cylinder, Triangular Arm and trace, main cat ladder assembly and spreading cat ladder assembly hinged, the fixed end of Triangular Arm is hinged on main cat ladder assembly, Triangular Arm intermediate active end is connected with trace, another movable end of Triangular Arm is with pulley, spreading cat ladder assembly is provided with slide plate, pulley matches with slide plate, the piston rod head of hydraulic cylinder drives Triangular Arm motion by trace, and then drive sheave propels skateboarding, spreading cat ladder assembly is launched, it is characterized in that: described main cat ladder assembly and hydraulic cylinder bias are installed, described main cat ladder assembly one end is fixedly mounted on cat ladder and installs on base for supporting, described hydraulic cylinder is arranged on hydraulic cylinder mounting base, described main cat ladder assembly is provided with numerical control detection device, described numerical control detection device is with detection head, the piston rod head of described hydraulic cylinder ejects apart from maximum when spreading cat ladder assembly is completely folding, eject apart from minimum when launching completely, all contact with described detection head at these two position piston rod heads, described numerical control detection device is by the start and stop of detection head accurate hydraulic control cylinder.
As preferred embodiment, described main cat ladder assembly and spreading cat ladder assembly face bonding are connected to the diamond plate of 5mm, and at diamond plate external welding monolithic reeding.
The present invention compared with prior art, its beneficial effect is: it completes the folding and expansion of main cat ladder assembly and spreading cat ladder assembly by Driven by Hydraulic Cylinder, and by the numerical control detection device arranged can accurately detect hydraulic pressure support cat ladder whether folding and expansion put in place, can the start and stop of more accurate hydraulic control cylinder, improve operating efficiency, reduce the labour intensity of workman.
