Description
Technical Field
The utility model belongs to the vehicle field, concretely relates to trailer railway carriage.
Background
At present, because the requirement on environmental protection is more and more strict in the vehicle transportation process, the trailer needs to be additionally provided with a tarpaulin device when transporting powdery and granular materials, thereby bringing great difficulty and trouble, and wasting time and energy when loading and unloading.
Disclosure of Invention
The utility model aims at avoiding the defect of prior art, providing a trailer railway carriage.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a trailer box characterized in that: the carriage body is fixed on the frame; the two sides of the upper end of the carriage body are symmetrically provided with top cover fixing seats; the left top cover and the right top cover are respectively and symmetrically connected to the top of the compartment body through the top cover fixing seats, so that the compartment body forms a closed whole; the left top cover and the right top cover can be opened relatively through the hinge structure.
The left top cover and the right top cover are both composed of a top cover A and a top cover B; the top cover A is arranged at the upper end of the carriage body through a top cover fixing seat; the hinge structure is as follows: the outer end of the top cover B is hinged with a first hinge mechanism, the other end of the first hinge mechanism is hinged with a first fixed seat, and the middle of the first hinge mechanism is hinged with a second hinge mechanism; one end of the third hinge mechanism is hinged with the second fixing seat, and the other end of the third hinge mechanism is hinged with the oil cylinder and the second hinge mechanism; the bottom end of the oil cylinder is hinged with a third fixed seat;
the first fixing seat, the second fixing seat and the third fixing seat are all welded on the carriage body.
And the top cover A and the top cover B are connected through a hinge.
The utility model has the advantages that: the automatic open closed top cap has been designed, and simple structure is reasonable, and convenient operation realizes fast loading and unloading goods, has improved work efficiency, reduces intensity of labour, and the practicality is strong, and the transportation is environmental protection more.

in the figure: the car comprises a car frame 1, a car body 2, a roof fixing seat 3, a roof A4, a hinge 5, a roof B6, a hinge mechanism 7, a hinge mechanism 8, a hinge mechanism II 9, a hinge mechanism III 10, a fixing seat I11, a fixing seat II 11, a fixing seat III 12 and an oil cylinder 13.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Embodiment 1, see fig. 1, a trailer wagon, its characterized in that: the carriage body 2 is fixed on the frame 1; the two sides of the upper end of the carriage body 2 are symmetrically provided with a top cover fixing seat 3; the left top cover and the right top cover are respectively and symmetrically connected to the top of the carriage body 2 through the top cover fixing seats 3, so that the carriage body forms a closed whole; the left top cover and the right top cover can be opened relatively through the hinge structure.
The left top cover and the right top cover are both composed of a top cover A4 and a top cover B6; the top cover A4 is connected with the top cover B6 through a hinge 5; the top cover A4 is arranged at the upper end of the carriage body 2 through the top cover fixing seat 3; the hinge structure is as follows: the outer end of the top cover B6 is hinged with a first hinge mechanism 7, the other end of the first hinge mechanism 7 is hinged with a first fixed seat 10, and the middle of the first hinge mechanism 7 is hinged with a second hinge mechanism 8; one end of a third hinge mechanism 9 is hinged with the second fixed seat 11, and the other end of the third hinge mechanism is hinged with an oil cylinder 13 and the second hinge mechanism 8; the bottom end of the oil cylinder 13 is hinged with a third fixed seat 12;
the first fixing seat 10, the second fixing seat 11 and the third fixing seat 12 are all welded on the carriage body 2.
The working process is as follows:
as shown in fig. 1, when the oil cylinder 13 extends out, the hinge structure rotates around the corresponding fixing seat, and the top cover rotates around the top cover fixing seat 3, so that the top cover is closed and fixed.
As shown in fig. 2, when the oil cylinder 11 is contracted, the hinge structure rotates around the corresponding fixing seat, and the top cover rotates around the top cover fixing seat 3, so that the top cover is gradually opened.
As shown in fig. 3, after the oil cylinder 11 is retracted, the hinge structure rotates around the corresponding fixing seat, and the top cover rotates around the top cover fixing seat 3 to achieve a fully opened state of the top cover.
