Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1-3, a stage semitrailer hydraulically opens a three-stage, which comprises a two-stage plate 4, a three-stage plate 1 and a stage overturning transition rotary arm 3, wherein one end of the two-stage plate 4 is connected with one end of the three-stage plate 1 through a circular hinge, the two-stage plate 4 and the three-stage plate 1 are respectively provided with a hydraulic cylinder 2, and the two-stage plate 4 and the three-stage plate 1 are respectively hinged with the telescopic ends of the corresponding hydraulic cylinders 2;

The stage overturning transition rotating arm 3 is arranged between the fixed ends of the two hydraulic cylinders 2 on the two-stage plate 4 and the three-stage plate 1, and the stage overturning transition rotating arm 3 is hinged with the shells of the hydraulic cylinders 2 on two sides.

Working principle:

the device turns the three-stage plate 1 to a horizontal state in two steps.

The three-stage table 1 is connected with the two-stage table 4 through a round hinge, and a turnover transition rotating arm is arranged at the hydraulic cylinder 2.

The overturning transition rotating arm is connected with the hydraulic cylinders 2 of the stage boards at the two sides, and when the stage is opened, the group of hydraulic cylinders 2 at the upper part is closed first to erect the three-stage board 1.

Then the hydraulic cylinder 2 at the lower part of the stage plate is closed to turn the three-stage to a horizontal state.

The unfolding and closing hydraulic system of the three-stage is integrated with the whole car hydraulic system to control, and the remote controller is used for operating.

The stage is additionally provided with a three-stage on the basis of hydraulically opening the two-stage; the three-stage board 1 turns over the stage board to 180 degrees through two groups of oil cylinders; the expansion of the stage plate is automatically completed through a hydraulic system, and manpower is not needed. The stage can increase the stage depth to about 12000 mm.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
