Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Example 1

The embodiment provides a semitrailer with assembled columns, as shown in fig. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15, comprising a side beam 5, wherein a plurality of lifting type split columns 1 and a plurality of compartment columns 3 are arranged on the side beam 5, and the lifting type split columns 1 and the compartment columns 3 are distributed at intervals.

The lifting type split upright post 1 comprises two upright posts 8 which are spliced together. The upper parts of the two upright columns 8 are provided with locking hooks 19 and fixing parts. The two upright columns 8 are detachably spliced through the locking hooks 19 and the fixing piece. And movable plug locking mechanisms are arranged at the bottoms of the two upright columns 8.

The movable plug locking mechanism comprises a plug board 9 which is arranged at the lower end of the inner cavity of the upright post 8 in a sliding manner. The plug board 9 is provided with a lifting pin fixing hole 14, and two sides of the lifting pin fixing hole 14 are provided with anti-rotation clamping holes 21. The plug board 9 is rotatably provided with a lifting pin 10, and the upright post 8 is vertically provided with a strip-shaped positioning hole 18. The upper end and the lower end of the strip-shaped positioning hole 18 extend towards the left and the right direction to form a circular arc-shaped positioning groove 17. One end of the pulling pin 10 is connected to the pulling pin fixing hole 14 through a locknut, a washer 12 and a spring 13. The other end of the lifting pin 10 extends out of the strip-shaped positioning hole 18.

The lifting pin 10 comprises a rotation limiting handle 15 and a threaded rod 16 arranged at one end of the rotation limiting handle 15. The inner side end face of the rotation limiting handle 15 is further provided with a pair of rotation preventing bosses 20 matched with the rotation preventing clamping holes 21.

Specifically, the side beam 5 is provided with an installation groove corresponding to the position of the lifting type split upright post 1. A compartment plate 2 and a fence 4 are detachably connected between the lifting type split upright post 1 and the compartment upright post 3.

And a vertical column reinforcing plate 11 is fixedly arranged in the inner cavity of the vertical column body 8.

One end of the fence 4 is provided with a fence rotating shaft 6, the other end of the fence 4 is provided with a fence locking hook 7, and the fence 4 is in rotating fit with the carriage upright post 3 through the fence rotating shaft 6. The fence 4 is connected with the lifting type split upright post 1 through a fence lock hook 7.

The bottom of the compartment plate 2 is matched with the boundary beam 5 in an overturning way through a hinge.

Wherein, this embodiment still provides the mounting tool of a pull pin is carried in installation, specifically as shown in fig. 14 and fig. 15, including installation handle and one end and the fixed locknut stationary blade of installation handle, hexagonal locknut card hole has been seted up at the both ends of installation handle, and the circular port has been seted up at the both ends of locknut stationary blade. When the locknut is installed, the hexagonal end of the locknut is placed in the hexagonal locknut clamping hole, and the circular end of the locknut is placed in the circular hole.

Specifically, the steps of opening the carriage of the semitrailer with the assembled upright post are as follows:

firstly, when the lifting pin is pulled outwards, the spring is compressed, the lifting pin is rotated by 90 degrees at the moment, the boss on the lifting pin is separated from the arc-shaped positioning groove, the lifting pin moves along the strip-shaped positioning hole to drive the plug board group to move up and down, when the lifting pin moves to the arc-shaped positioning groove at the upper part of the upright post, the lifting pin is rotated in the opposite direction, the boss of the lifting pin is embedded into the arc-shaped positioning groove at the upper part again to release the handle, the lifting pin cannot rotate under the action of the spring any more, the lifting pin is blocked by the arc-shaped positioning groove and cannot slide downwards, and at the moment, the plug group is completely retracted into the upright post body. And when the plug board is required to extend out, the operation is reversed.

Then, the handles at the two ends of the carriage plate are respectively opened, the locking hooks and the fixing parts on the lifting type split upright posts are turned downwards and opened, the fence is turned outwards, and the lifting type split upright posts can be driven to rotate together, so that the carriage opening action is completed.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
