Abstract
The utility model discloses a hydraulic pressure is from extending cat ladder, it includes base, upper segment cat ladder, saves cat ladder, hydro -cylinder down, the one end of upper segment cat ladder articulates on the base, and the other end is articulated with lower section cat ladder, it has the bracing piece still to articulate on the base, the bracing piece passes through the triangle arm and links to each other with lower section cat ladder in the upper segment cat ladder respectively, the bracing piece still links to each other with lower section cat ladder through the connecting rod, the one end of connecting rod is cup jointed on the bracing piece through the sliding sleeve, and the other end of connecting rod is equipped with the lug, it is equipped with the recess corresponding with the lug on the cat ladder to save down, upper segment cat ladder, the upper surface that saves the cat ladder down are equipped with the slipmat, the sliding sleeve articulates on the connecting rod. The utility model discloses simple structure, safe and reliable, economical and practical have improved the operating efficiency, have reduced workman's intensity of labour, have reduced because the possibility of the emergence incident that the manual operation cat ladder arouses is fit for promoting on a large scale.
Description
Technical field
The utility model relates to a kind of cat ladder, is specifically related to a kind of hydraulic pressure from stretching cat ladder.
Background technology
To pave the way the large-scale engineering machineries such as road machinery, roller that pave often used at highway.This type of large-scale engineering machinery is because hill climbing ability is poor and self is heavier, and transport hourly velocity is slower.Conveniently transport need be used special transportation vehicle and shifted, but the upper and lower vehicle of this type of large-scale engineering machinery is comparatively inconvenient, need install cat ladder with this afterbody at vehicle chassis.But in existing cat ladder, some cat ladders are short and small causes the angle of climbing being difficult to reach construction machinery and equipment; Some cat ladders are collapsible, add the length of cat ladder, reduce angle of climbing, but cat ladder freely can not stretch and opens, not only complicated operation but also dangerous.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hydraulic pressure from stretching cat ladder, its structure is simple, safe and reliable, economical and practical, improve operating efficiency, reduce the labour intensity of workman, decrease the possibility of the generation safety misadventure caused due to manual operation cat ladder, be applicable to carrying out large-scale promotion.
Technical problem to be solved in the utility model is taked following technical scheme to realize:
A kind of hydraulic pressure is from stretching cat ladder, it comprises pedestal, upper joint cat ladder, lower joint cat ladder, oil cylinder, one end of described upper joint cat ladder is hinged on pedestal, the other end and lower joint cat ladder hinged, described pedestal is also hinged with strut bar, described strut bar is connected with lower joint cat ladder respectively at upper joint cat ladder by Triangular Arm, described strut bar is also connected with lower joint cat ladder by connecting rod, one end of described connecting rod is socketed on strut bar by sliding sleeve, the other end of connecting rod is provided with projection, and described lower joint cat ladder is provided with the groove corresponding with projection.
The upper surface of described upper joint cat ladder, lower joint cat ladder is provided with slipmat.
Described sliding sleeve is hinged on connecting rod.
The beneficial effects of the utility model are: the utility model structure is simple, safe and reliable, economical and practical.Between lower joint cat ladder and strut bar, add a connecting rod, cat ladder is stretched more freely, reliably, there is good economical and practical value; The upper surface of upper joint cat ladder, lower joint cat ladder is equipped with slipmat, improves the friction force on cat ladder surface, thus improves the hill climbing ability of large-scale engineering machinery.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: pedestal 1, upper joint cat ladder 2, lower joint cat ladder 3, oil cylinder 4, strut bar 5, Triangular Arm 6, connecting rod 7, sliding sleeve 8, projection 9, groove 10, slipmat 11.
Detailed description of the invention
In order to technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of hydraulic pressure is from stretching cat ladder, it comprises pedestal 1, upper joint cat ladder 2, lower joint cat ladder 3, oil cylinder 4, one end of described upper joint cat ladder 2 is hinged on pedestal 1, the other end and lower joint cat ladder 3 hinged, described pedestal 1 is also hinged with strut bar 5, described strut bar 5 is connected with lower joint cat ladder 3 respectively at upper joint cat ladder 2 by Triangular Arm 6, strut bar 5 is also connected with lower joint cat ladder 3 by connecting rod 7, one end of connecting rod 7 is socketed on strut bar 5 by sliding sleeve 8, the hinged projection 9 of the other end of connecting rod 7, lower joint cat ladder 3 is provided with the groove 10 corresponding with projection 9.
The upper surface of upper joint cat ladder 2, lower joint cat ladder 3 is provided with slipmat 11.
Sliding sleeve 8 is hinged on connecting rod 7.
When using hydraulic pressure from the work of stretching, extension cat ladder, under the driving of oil cylinder 4, drive Triangular Arm 6 to rotate around hinge-point by strut bar 5, with make lower joint cat ladder 3 drive while expansion described on save cat ladder 2 and carry out Automatic-expanding, and slide in one end of connecting rod 7 on strut bar 5, thus joint cat ladder 3 stretches under promoting, further drive saves cat ladder 2 Automatic-expanding, the use of cat ladder can be carried out.In cat ladder decentralization process, upper and lower joint cat ladder can stretch automatically, has good economical and practical value.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
