Abstract
The utility model provides a foldable low flat-car ladder. The foldable low flat-car ladder comprises a movable ladder body, a folding ladder body and a hydraulic system, wherein the movable ladder body is arranged on a rotating shaft, and the folding ladder body is hinged to the movable ladder body; the folding ladder body is provided with a pull rope fixing shaft; a pulley is arranged at the hinged end of the movable ladder body, and another pulley corresponding to the pulley of the movable ladder body is arranged at the hinged end of the folding ladder body. The foldable low flat-car ladder can meet the requirements for the height of a bearing surface and the height of a whole vehicle; when the foldable low flat-car ladder needs to be lengthened and the climbing angle needs to be reduced, the folding ladder body can be put down, and therefore the climbing angle is reduced, the vehicle climbs up and down the foldable low flat-car ladder more conveniently and rapidly, and safety is improved when the vehicle is loaded.
Description
Technical field
The utility model relates to a kind of cat ladder, is specifically related to the low flat truck cat ladder of a kind of folding.
Background technology
Existing low flat truck cat ladder is all to add spring-loaded overall cat ladder, use steel rope pull-up, then fix with fixed pin shaft, when carrying surface height and car load height have specific (special) requirements time, cat ladder is generally all shorter, the angle on cat ladder and ground is just larger like this, the upper and lower cat ladder of inconvenient engineering truck, and entrucking is abnormally dangerous.
Utility model content
The utility model, for problems of the prior art, provides the low flat truck cat ladder of a kind of folding folding low flat truck cat ladder.
The low flat truck cat ladder of folding of the present utility model, comprises the autostairs that is located in rotating shaft and attic ladder and the hydraulic efficiency pressure system hinged with it; Attic ladder is provided with stay cord anchor shaft; The pin jointed end of autostairs is provided with pulley, and the pin jointed end of attic ladder is provided with another pulley corresponding with pulley.
For the safety connecting, described autostairs and attic ladder are hinged by connecting panel.
In order to make the attic ladder can contact more stable with ground, the front end of described attic ladder be provided with diagonal plane.
For pulley plays a role better, described stay cord anchor shaft is located at the middle part of attic ladder.
The relative prior art of the utility model has the following advantages: folding structure of the present utility model, can meet carrying surface height and car load height, run into need to lengthen cat ladder and reduce ramp angle time, folded part can be put down, realize and reduce ramp angle, make the upper and lower cat ladder more convenient and quicker of vehicle, the safety while having improved entrucking.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the working state schematic representation of the low flat truck cat ladder of the utility model folding.
The specific embodiment
Below with reference to accompanying drawing, the low flat truck cat ladder of folding of the present utility model is described in further detail.
The low flat truck cat ladder of folding as shown in Figure 1 and Figure 2, comprises the autostairs 1 that is located in rotating shaft 3 and attic ladder 2 and the hydraulic efficiency pressure system hinged with it; Autostairs 1 is hinged by connecting panel 7 with attic ladder 2; The middle part of attic ladder 2 is provided with stay cord anchor shaft 6, and the front end of attic ladder 2 is provided with diagonal plane; The pin jointed end of autostairs 1 is provided with pulley 8, and the pin jointed end of attic ladder 2 is provided with another pulley corresponding with pulley 8.
When use, autostairs 1 is fixed on vehicle tail end by bearing, and attic ladder 2 is fixed on autostairs 1 by connecting panel 7 and bearing pin 5; In the time that oil cylinder 9 is retracted, oil cylinder attaching parts 10 rotates, thereby make autostairs 1 decline that rotates backward, in the time that autostairs 1 drops to certain angle, stay cord 4 is strained and is acted on the stay cord anchor shaft 6 of attic ladder 2, attic ladder 2 lower ends are pulled upwardly and decline with autostairs 1, finally make autostairs 1 and attic ladder 2 at grade above, and the diagonal plane part of attic ladder 2 leading portions just contacts with ground forming surface, cat ladder is thoroughly opened, present deployed condition, realize cat ladder and lengthen, reduce with the angle on ground; And in the time that oil cylinder 9 stretches out, the power acting on oil cylinder attaching parts 10 makes autostairs 1 rotate with oil cylinder attaching parts 10, autostairs 1 starts to rise, and in the time that autostairs 1 is raised to certain altitude, attic ladder 2 starts to fold under the effect from gravity, realizes folded state.
