Description

Technical Field

[0001] The present invention relates to a reinforcement device for a railway flat car. Background Art

[0002] Currently, when various crawler vehicles and wheeled vehicles are transported by railway general flat cars, in order to ensure the safety and reliability of the wheeled and crawler vehicles during railway transportation, according to the "Rules for Loading and Reinforcement of Railway Goods", wooden blocks need to be set on the front and rear sides of the vehicle tires (crawlers), and the blocks are nailed to the flat car floor with grab nails. According to usage habits, triangular blocks are used for wheeled vehicles for blocking and fixing, and square timbers are used for crawler vehicles for blocking and fixing. Since there is a certain angle between the grab nails and the floor when nailing into the flat car floor, a crowbar is needed to pry out the nails when removing them, resulting in a much higher degree of damage to the flat car floor by using the grab nails compared to round steel nails; at the same time, using a crowbar to remove the nails will damage the wooden blocks and grab nails, resulting in both the wooden blocks and grab nails used in the existing reinforcement being disposable reinforcement materials, which are difficult to recycle and cause a great waste of resources. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a reinforcement device for a railway flat car, which can not only reduce the damage to the flat car floor and wooden blocks during the nail removal process, but also increase the number of times the wheel blocks can be recycled.

[0040] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto.

[0041] Example 1

[0042] Figure 1 Schematic diagram of the structure of the reinforcement device for the railway flatcar in this embodiment. Figure 2 Schematic diagram of the usage state in this embodiment. Figure 3 Front view schematic diagram of the connection structure in this embodiment.

[0043] As Figures 1 to 3 shown, the reinforcement device for the railway flatcar in this embodiment is arranged on the railway flatcar floor 100 and is used to block and fix the vehicles loaded on the railway flatcar.

[0044] As shown Figure 1 in the figure, the reinforcement device for the railway flat car includes a wheel stopper 1, a connection structure 2, and a connecting piece 3. One end of the connection structure 2 is fixed to the wheel stopper 1, and the other end is connected to the flat car floor 100. Specifically, as shown Figure 1 and Figure 3 in the figure, the connection structure 2 includes a connecting rod 21, a first connection part 22, a second connection part 23, and a reinforcing rib 24. The connecting rod 21, the first connection part 22, the second connection part 23, and the reinforcing rib 24 are made of Q355B low-alloy high-strength structural steel and are integrally forged, which can improve the number of times the reinforcement device can be recycled.

[0045] The connecting rod 21 includes a main body 211 and a first end 212. The main body 211 and the first end 212 are bent and connected, and an obtuse angle is formed between them. In this way, the connecting rod 21 as a whole is basically in the shape of an obtuse-angled "√"-shaped rod structure. A third groove 2111 is provided on the lower side of the main body 211 of the connecting rod 21.

[0046] The first connection part 22 is arranged at one end of the main body 211. A first connection hole 221 is provided on its first side I, and a first groove 222 is provided on its second side II. The connecting piece 3 passes through the first connection hole 221 and the first groove 222 to fix the first connection part 22 to the wheel stopper 1. The upper side III of the main body 211 is coplanar with the first side I of the first connection part 22, and the lower side IV of the main body 211 is coplanar with the second side II of the first connection part 22.

[0047] The second connection part 23 is arranged at the end of the first end 212 away from the main body 211. A second connection hole 231 is provided at its top, and a second groove 232 is provided at its bottom. The connecting piece 3 passes through the second connection hole 231 and the second groove 232 to fix the second connection part 23 to the flat car floor 100. The top of the second connection part 23 is coplanar with the top of the first end 212 of the connecting rod 21, and the bottom of the second connection part 23 is coplanar with the bottom of the first end 212 of the connecting rod 21.

[0048] In this embodiment, the width of the first groove 222 is equal to the width of the second groove 232; the width of the third groove 2111 is greater than the widths of the first groove 222 and the second groove 232 respectively.

[0049] As shown Figure 2As shown in the figure, the wheel chock 1 of this embodiment is a triangular wheel chock, and the connecting piece 3 is a round steel nail. The body 211 of the connecting rod 21 is attached to the inclined surface of the triangular wheel chock, and the first end 212 of the connecting rod 21 is attached to the flat car floor 100. The included angle between the body 211 and the first end 212 of the connecting rod 21 can be adjusted according to the slope of the triangular wheel chock. The connecting piece 3 is perpendicular to the inclined surface of the triangular wheel chock and the flat car floor 100 respectively. The arrangement in cooperation with the first groove 222 and the second groove 232 is more conducive to nail removal. After nail removal, only holes with the same diameter as the connecting piece 3 are generated on the flat car floor 100, thus playing a protective role for the floor.

[0050] The reinforcing rib 24 is arranged above the connecting rod 21 and is arranged along the length direction of the connecting rod 21 to improve the strength of the connecting structure 2.

[0051] Example 2

[0052] Figure 4 is a schematic structural diagram of the reinforcement device for railway flat cars of this embodiment. Figure 5 is a schematic diagram of the use state of this embodiment. Figure 6 is a front view schematic diagram of the connecting structure of this embodiment.

[0053] As Figures 4 to 6 shown, the difference between the reinforcement device for railway flat cars of this embodiment and that of Embodiment 1 is that: the wheel chock of this embodiment is a square wood chock; the connecting rod 21 further includes a second end 213, wherein the second end 213 is arranged between the body 211 and the first connecting portion 22, and the second end 213 is bent and connected to the body 211. Specifically,

[0054] As Figure 6 and Figure 5 shown, the body 211 and the second end 213 of the connecting rod 21 are arranged to support the side surface of the square wood chock, and the first end 212 is attached to the flat car floor 100;

[0055] The inner side surface V of the second end 213 is coplanar with the first side surface I of the first connecting portion 22;

[0056] The outer side surface VI of the second end 213 is coplanar with the second side surface II of the first connecting portion 22.

[0057] The following makes a detailed description of the usage method of the reinforcement device for railway flat cars of the present invention.

[0058] As Figure 2 and Figure 5As shown, before reinforcing the flat car floor 100, first use the connector 3 to reinforce one end of the connecting structure 2 with the wheel chock 1. After the wheeled vehicle or tracked vehicle is installed to a suitable position on the flat car, the reinforcing device is tightly closed with the vehicle tire 200 or the vehicle track 300. At the same time, use the connector 3 to reinforce the other end of the connecting structure 2 with the flat car floor 100, and the vehicle reinforcement operation can be completed.

[0059] When removing nails, insert the crowbar into the first groove 222 and the second groove 232 at the contact position between the connecting structure 2 and the flat car floor 100. Since one side of the crowbar is in contact with the flat car floor 100, it will play a certain protective role on the flat car floor 100. After the nails are removed, only nail holes with the same diameter as the round steel nails are generated on the flat car floor 100, thereby protecting the floor to a greater extent.

[0060] The present invention is not limited to the above-mentioned embodiments. Without departing from the essential content of the present invention, any deformation, improvement and substitution that can be conceived by those skilled in the art shall fall within the scope of the present invention.
