detailed description

The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 , an opening and closing top cover for a railway wagon provided by an embodiment of the present invention mainly includes: a cylinder 1, a connecting rod 2, a movable top cover 3, a longitudinal positioning device 4, and a roller 5. The opening and closing top cover for the railway wagon adopts a connecting rod slider mechanism, and the connecting rod 2 and the movable top cover 3 respectively correspond to two connecting rods in the connecting rod slider mechanism, and the roller 5 is equivalent to the connecting rod slider mechanism Slider.

The connection relationship and function of each component are specifically described below.

One end of the cylinder 1 is hinged to the middle of the connecting rod 2, and the other end of the cylinder 1 is hinged to the end wall 7 of the vehicle body. The cylinder 1 is a two-way acting cylinder and is a driving source of the movable top cover 3.

One end of the link 2 is hinged to one side of the movable top cover 3, and the other end of the link 2 is hinged to the vehicle body end wall 7. In addition to the driving force provided by the cylinder 1, the connecting rod 2 also functions to support the movable top cover 3.

The movable top cover 3 is used to cover the loading port provided on the roof 6. In addition, a sealing rubber ring is provided around the charging port provided on the roof 6.

In addition, a longitudinal positioning device 4 is provided on the other side of the movable top cover 3 to provide longitudinal positioning of the movable top cover 3. For better positioning, a longitudinal positioning device 4 should also be provided at the other end of the movable roof 3.

The other side of the movable top cover 3 is provided with a set of rollers 5 slidable along the roof 6 to provide support and sliding for the movable top cover 3.

The movable top cover 3, the longitudinal positioning device 4 and the roller 5 can be assembled in one piece.

As shown in FIG. 1 , when the movable top cover 3 is in the closed state, the piston rod of the cylinder 1 is extended, the driving link 2 rotates forward around the support point of the second end of the connecting rod 2, and the connecting rod 2 rotates in the forward direction (ie, Turning clockwise) causes the movable top cover 3 to slide open along the roof 6 by the roller 5.

As shown in FIG. 2, when the movable top cover 3 is in an open state, the piston rod of the cylinder 1 contracts, the drive link 2 rotates in the opposite direction around the support point of the second end of the connecting rod 2, and the reverse rotation of the connecting rod 2 drives the movable top. The cover 3 is slidably closed along the roof 6 by the roller 5.
