Detailed Description

Exemplary embodiments that embody features and advantages of the invention are described in detail below in the specification. It is to be understood that the invention is capable of other embodiments and that various changes in form and details may be made therein without departing from the scope of the invention and the description and drawings are to be regarded as illustrative in nature and not as restrictive.

For further explanation of the principles and construction of the present invention, reference will now be made in detail to the preferred embodiments of the present invention, which are illustrated in the accompanying drawings.

Referring to fig. 1 and 2, the present application provides a rail flatcar 1 moving on an electrified rail to perform a transfer of a semi-trailer frame 2, the rail flatcar 1 including a flatcar body 11, a transfer unit 12, and a movable plate 13.

Specifically, the flatcar body 11 includes a platform 111 and a traveling mechanism 112. The traveling mechanism 112 of the present embodiment is a wheel that moves along a rail laid on the ground, and the traveling direction of the wheel is parallel to the longitudinal direction of the platform 111. The track matched with the wheel is electrified with 36V direct current, and the track is insulated to the ground so as to ensure the personal safety of operators.

Further, the transfer unit 12 is provided in plurality and arranged at intervals along the length direction of the platform 111. Each transfer unit 12 comprises a support 121, a rolling assembly and a mobile plate 13. Wherein the bottom of the support 121 is fixedly mounted on the upper surface of the platform 111. The rolling assembly includes a plurality of rollers 122 arranged along the width direction of the platform 111, the rollers 122 are rotatably mounted on the support 121, and the axial direction of the rollers 122 is parallel to the length direction of the platform 111. The movable plate 13 is used for carrying the frame 2 of the semitrailer, and the movable plate 13 is laid on the rollers 122 and can move along the width direction of the platform 111 along with the rotation of the rollers 122.

In the rail flat car 1 of the present embodiment, the movable plate 13 of the transfer unit 12 is used to carry the frame 2 of the semitrailer along the width direction of the platform 111; along the length of the platform 111, a plurality of transfer units 12 co-operate to provide support for the frame 2 of the semitrailer, thereby ensuring stable placement of the frame 2 on the rail vehicle 1.

As shown in fig. 2, the support 121 includes a support 1211 and a mounting table 1212 disposed above the support 1211. Each support 121 includes two struts 1211, and the two struts 1211 are spaced below the mounting table 1212 to form a stable support structure. In the present embodiment, the pillars 1211 are square pipes of 150mm × 5mm, and the bottom of each pillar 1211 is fixedly mounted on the upper surface of the platform 111 by screws.

further, the length direction of the mounting table 1212 of the present embodiment is parallel to the width direction of the platform 111, and the mounting table 1212 is divided into a first mounting area 1213 and a second mounting area 1214 along the length direction thereof.

In the present embodiment, the roller 122 is mounted in the first mounting area 1213, and the movable plate 13 moves in the first mounting area 1213 in response to the rotation of the roller 122. When the frame 2 on the rail flat car 1 needs to be hung up, when the frame 2 is pushed or hoisted at one side of the length direction of the frame 2, the frame 2 can move on the movable plate 13 along with the rotation of the roller 122, so as to gradually separate from the mounting table 1212. In the whole hanging process, direct sliding friction cannot be generated between the bottom of the frame 2 and the upper surface of the mounting table 1212, so that manpower and material resources in hanging operation are saved, and the frame 2 and the rail flat car 1 are prevented from being worn.

The second mounting area 1214 of this embodiment is fixedly mounted with a support plate 14, the upper surface of the support plate 14 being used to cooperate with the movable plate 13 to jointly carry the frame 2 of the semitrailer. The supporting plate 14 is fixed relative to the mounting table 1212, and when the supporting plate 14 and the movable plate 13 jointly carry the frame 2 of the semitrailer, the situation that the frame 2 of the semitrailer slides off from the mounting table 1212 due to the rotation of the roller 122 can be avoided. In the present embodiment, the support plate 14 and the movable plate 13 are both made of polyethylene, and the support plate 14 and the movable plate 13 are both 30mm thick.

Preferably, the length of the first mounting area 1213 is greater than the length of the second mounting area 1214. This arrangement can ensure the travel of the movable plate 13 moving on the mounting platform 1212 on the premise that the supporting plate 14 is mounted on the mounting platform 1212, so as to ensure that no sliding friction occurs between the frame 2 and the rail flat car 1 before the frame 2 is separated from the rail flat car 1.

Further, as shown in fig. 2 and 3, the mount 1212 of the present embodiment has an H-shaped longitudinal section. Both ends of the length direction of the mounting table 1212 are provided with sealing plates 15, and the sealing plates 15 and the mounting table 1212 jointly enclose a groove 16 with an open top. Wherein the top opening of the groove 16 is its notch.

In the roller 122 assembly of the present embodiment, each roller 122 is mounted in the groove 16 through the rotating shaft 17. Specifically, two ends of the rotating shaft 17 are respectively fixed on two inner side walls of the groove 16, and the axial direction of the rotating shaft 17 is parallel to the length direction of the platform 111. The roller 122 is rotatably mounted on the shaft 17, and the top end of the roller 122 is lower than the notch of the groove 16.

When the movable plate 13 is placed above the roller 122, the movable plate 13 is partially received in the groove 16, i.e., the upper surface of the movable plate 13 is higher than the notch of the groove 16, and the lower surface is lower than the notch of the groove 16. When the movable plate 13 moves along with the rotation of the roller 122, the sealing plate 15 at the end of the mounting block 1212 can function as a stop to prevent the movable plate 13 from sliding out of the mounting block 1212.

Further, a fixing block 18 is disposed inside the groove 16, the fixing block 18 is disposed in the second mounting area 1214 of the mounting table 1212, and both ends of the fixing block 18 are respectively fixed to both inner sidewalls of the groove 16. The fixing block 18 of this embodiment is disposed adjacent to the notch of the groove 16, and the upper surface of the fixing block 18 is lower than the notch of the groove 16.

In this embodiment, the upper surface of the fixing block 18 is used for placing the support plate 14. When the support plate 14 is placed on the fixing block 18, the upper surface of the support plate 14 is higher than the notches of the grooves 16, and the lower surface is lower than the notches of the grooves 16. The support plate 14 is partially received in the recess 16 and the closure plate 15 at the end of the mounting block 1212 stops the support plate 14 from being removed from the mounting block 1212.

Preferably, the upper surface of the support plate 14 is flush with the upper surface of the movable plate 13. This arrangement allows the bearing surface of the support plate 14 and the bearing surface of the movable plate 13 to be located in the same plane, so as to further ensure the stable placement of the semi-trailer frame 2 above the mounting table 1212.

when the rail flat car is used for transferring the frame of the semitrailer, the plurality of transferring units can provide stable support for the frame in the length direction of the platform; in the width direction of the platform, the movable plate and the supporting plate jointly bear the frame, and the frame can be prevented from sliding off in the running process of the rail flat car. When the frame of the semitrailer needs to be hung up, the frame is pushed or hoisted on one side of the length direction of the frame, so that the frame can move on the movable plate along with the rotation of the rollers, and is gradually separated from the mounting platform. In the process, the frame is moved by the aid of the movable plate and the idler wheels, so that sliding friction between the frame and the mounting platform is effectively avoided, manpower and material resources in hanging operation are saved, and abrasion between the frame and the rail flat car is prevented.
