[0001] The utility model relates to the technical field of armored vehicle transportation, in particular to a longitudinal stopper for transporting armored vehicles on a railway flat car. Background Art

[0002] During military exercises or actual combat deployment, armored vehicles often need to be loaded and transported quickly and long distances to designated areas via railway flat cars. In order to ensure safety and reliability during transportation, armored vehicles must be fixed on railway flat cars during transportation. The existing fixing method usually uses steel rope zippers to tie the wheels of the armored vehicle to the rope bolts of the flat car, and uses wedges to stop the armored vehicle to prevent it from moving longitudinally during emergency braking or marshaling operations of the train. However, this bundling and fixing method is time-consuming and labor-intensive, which reduces the stopping efficiency of transporting armored vehicles. Summary of the invention

[0003] In order to solve the problem that the existing bundling and fixing method is time-consuming and labor-intensive, and reduces the rapid response capability of armored vehicle transportation, the utility model proposes a longitudinal stopper for transporting armored vehicles on a railway flat car, by placing a first stop rod in a first through groove of a stopper seat, and the first stop rod cooperates with the second stop rod to place a wheel stopper on one side of the wheel, thereby achieving rapid stopping of the armored vehicle on the railway flat car. Since the longitudinal stopper is arranged on the railway flat car, the rapid response capability of the armored vehicle transportation is improved.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a longitudinal stop for transporting armored vehicles on a railway flat car, which is arranged on the side of the bottom beam of the railway flat car, and the longitudinal stop includes a connecting plate, which is fixed to the side of the bottom beam, and the side of the connecting plate away from the bottom beam is slidably connected to a stop seat, and the side of the stop seat away from the connecting plate is provided with a first through groove and a second through groove, the first through groove and the second through groove are connected to each other, the first through groove passes through the upper top surface of the stop seat, and the second through groove passes through the side or bottom surface of the stop seat, the first stop rod is movably placed in the first through groove or the second through groove, the end of the first stop rod away from the stop seat is hinged with the second stop rod, and the end of the second stop rod is fixed with a wheel stopper.

[0005] Furthermore, a third through slot is formed on the connecting plate, and a "T"-shaped sliding block which is slidably connected to the third through slot is fixed on one side of the stop seat close to the connecting plate.

[0006] Furthermore, a bolt is threadedly connected to the stop seat, and the end of the bolt extends out of the stop seat and abuts against the connecting plate. When the bolt is pressed against the connecting plate, the stop seat is in a fixed state on the connecting plate.

[0007] Further, one end of the first stopper rod is located at the connection between the first through slot and the second through slot, and a sliding rod is rotatably connected at the connection between the first through slot and the second through slot, and one end of the sliding rod passes through the first stopper rod, the stopper seat and the slider in sequence, and a second baffle is fixed to the end thereof, and the other end of the sliding rod is fixed to the first baffle, and a spring is provided on the sliding rod, and the spring is located between the second baffle and the slider, and the sliding rod is fixedly connected to the first stopper rod. The spring cooperates with the second baffle to apply a pulling force to the first stopper rod to prevent the sliding rod from directly detaching from the stopper seat with the first stopper rod, and the second baffle can prevent the sliding rod and the first stopper rod from being lost.

[0008] Furthermore, a limiting groove is provided on the end surface of the first stop rod away from the stop seat, and the limiting groove passes through the first stop rod on the side close to the railway flat car, and a hinge shaft is provided in the limiting groove, and the second stop rod is hinged to the first stop rod through the hinge shaft.

[0024] like Figure 1 to Figure 7 As shown, this embodiment provides a longitudinal stopper for transporting armored vehicles on a railway flat car, which is arranged on the side of the bottom beam 2 of the railway flat car 1. The longitudinal stopper includes a connecting plate 3, which is fixed to the side of the bottom beam 2. The side of the connecting plate 3 away from the bottom beam 2 is slidably connected to a stopper seat 4;

[0025] Specifically, the connecting plate 3 is provided with a third through slot 12, and a T-shaped slider 13 is fixed on one side of the stopper 4 close to the connecting plate 3 and is slidably connected to the third through slot 12. Figure 4 As shown, the fixed slide block 13 on one side of the stop seat 4 can slide in the third through slot 12 provided on the connecting plate 3 , thereby adjusting the position of the stop seat 4 on the connecting plate 3 .

[0026] When the stopper 4 is in a proper position on the connecting plate 3, a bolt 14 is threadedly connected to the stopper 4, and the end of the bolt 14 extends out of the stopper 4 and abuts against the connecting plate 3. When the bolt 14 is pressed against the connecting plate 3, the position of the stopper 4 on the connecting plate 3 is fixed, and when the bolt 14 is loosened, the stopper 4 is in a slidable state on the connecting plate 3.

[0027] The side of the stopper seat 4 away from the connecting plate 3 is provided with a first through slot 5 and a second through slot 6, the first through slot 5 and the second through slot 6 are connected to each other, the first through slot 5 passes through the upper top surface of the stopper seat 4, the second through slot 6 passes through the side surface or the bottom surface of the stopper seat 4, and the first stopper rod 7 is movably placed in the first through slot 5 or the second through slot 6;

[0028] Specifically, the first through slot 5 is connected to the second through slot 6 to form an "L" shape, an inverted "T" shape or a cross shape. In this embodiment, Figure 2 As shown, the first through slot 5 is connected to the second through slot 6 to form an "L" shape, and the first stop rod 7 is placed in the first through slot 5. When the stop is not in use, the first stop rod 7 is placed in the second through slot 6. The "L" shape allows the first stop rod 7 to have only a vertical state and a horizontal state.

[0029] One end of the first stop rod 7 is located at the connection between the first through slot 5 and the second through slot 6. The connection between the first through slot 5 and the second through slot 6 is rotatably connected with a sliding rod 8, and the sliding rod 8 is fixedly connected to the first stop rod 7.
