[0041] Specifically, in some embodiments, the front crossbeam 2011, the rear crossbeam 2012, and the longitudinal beam 2013 are all made of steel beams with a U-shaped cross-section. In other embodiments, the front crossbeam 2011, the rear crossbeam 2012, and the longitudinal beam 2013 can be made of steel beams with other cross-sectional shapes, such as I-beams, H-beams, or C-beams.

[0042] Please continue reading. Figures 3 to 6 In some specific embodiments, the track frame 201 also includes a front transverse liner 2016 and a rear transverse liner 2017, which are arranged in parallel between the two longitudinal beams 2013 and fixed to the top of the tank car 1. The front transverse liner 2016 is used to limit the front top cover 202, and the rear transverse liner 2017 is used to limit the rear top cover 203.

[0043] Specifically, in some embodiments, both the front crossbeam 2016 and the rear crossbeam 2017 are made of steel beams with a U-shaped cross-section. In other embodiments, the front crossbeam 2016 and the rear crossbeam 2017 may also be made of steel beams with other cross-sectional shapes, such as I-beams, H-beams, or C-beams.

[0044] Please continue reading. Figure 3 and Figure 6 In some specific embodiments, the front top cover 202 has several front top cover rollers 206 on its left and right sides for sliding engagement with two first tracks 2014. The front ends of both longitudinal beams 2013 are provided with first process holes 2013a to facilitate the entry and exit of the front top cover rollers 206. The sliding engagement between the front top cover rollers 206 and the first tracks 2014 makes the front top cover 202 slide more easily with less friction, making it easier to open and close. The first process holes 2013a at the front ends of the longitudinal beams 2013 facilitate the smooth entry of the front top cover rollers 206 into the longitudinal beams 103 during installation of the front top cover 202, and also facilitate the easy removal of the front top cover rollers 206 from the longitudinal beams 2013 during future maintenance.

[0045] Specifically, in some embodiments, the front cover roller 206 uses a U-shaped track pulley, and the first track 2014 uses a cylindrical linear track. In other embodiments, the front cover roller 206 may use a V-shaped track pulley, an H-shaped track pulley, or other types of track wheels, and the first track 2014 may use a rectangular linear track, a trapezoidal linear track, or other types of track.

[0046] Please continue reading. Figure 3 and Figure 6 In some specific embodiments, the rear top cover 203 has several rear top cover rollers 207 on its left and right sides for sliding engagement with two second tracks 2015. The rear ends of both longitudinal beams 2013 are provided with second process holes 2013b to facilitate the entry and exit of the rear top cover rollers 207. The sliding engagement between the rear top cover rollers 207 and the second tracks 2015 makes the rear top cover 203 slide more easily with less friction, thus facilitating opening and closing. The second process holes 2013b at the rear ends of the longitudinal beams 2013 facilitate the smooth entry of the rear top cover rollers 207 into the longitudinal beams 2013 during installation, and also facilitate easy removal of the rear top cover rollers 207 from the longitudinal beams 2013 during future maintenance.

[0047] Specifically, in some embodiments, the rear top cover roller 207 uses a U-shaped track pulley, and the second track 2015 uses a cylindrical straight track. In other embodiments, the rear top cover roller 207 may use a V-shaped track pulley, an H-shaped track pulley, or other types of track wheels, and the second track 2015 may use a rectangular straight track, a trapezoidal straight track, or other types of track.

[0048] See Figures 3 to 6 In some specific embodiments, a support seat 208 for supporting the front cover opening cylinder 204 is provided on the front side of the front cover 202. By providing the support seat 208, it is possible to effectively prevent the front cover opening cylinder 204 from falling downward due to the gravity of the front cover 202 after it is opened (i.e. extended), causing the front cover opening cylinder 204 to get stuck when it is closed (i.e. retracted).

[0049] Specifically, please continue reading Figure 9 and Figure 11In some specific embodiments, the support 208 includes a support beam 2081 and a support roller 2082 rotatably mounted on the support beam 2081; wherein, the rear end of the support beam 2081 is fixedly connected to the front side of the front top cover 202, and the front end is rotatably connected to the support roller 2082; in use, the front top cover opening cylinder 204 slides on the support roller 2082, and when the front top cover 202 slides along the track frame 201 under the pushing action of the front top cover opening cylinder 204, the support 208 also slides accordingly. When the support 208 moves, the roller 2082 will support the front cover opening cylinder 204. The purpose of using the roller 2082 to support the front cover opening cylinder 204 is twofold: firstly, it can prevent the front cover opening cylinder 204 from falling downwards due to the gravity of the front cover 202 after it is opened, which would cause the front cover opening cylinder 204 to get stuck when it is closed; secondly, it can reduce the friction between the front cover opening cylinder 204 and the support 208, and avoid wear on the surface of the front cover opening cylinder 204.
