Description

Technical Field

[0001] The present invention belongs to the technical field of railway equipment and devices, and more specifically, relates to a rotatable structural rail transport support device and a railway freight car. Background Art

[0002] This crucial component of railway construction, approximately twice the length of a typical flatcar in my country, presents numerous challenges in transportation. In the early days, my country used specialized vehicles for transporting long rails, specifically 25m long rails. However, due to the low availability, insufficient capacity, and high transportation costs of these vehicles, my country began adopting a flatcar-coupled transport method to address these challenges. Transporting 25m long rails using two flatcars coupled together has become the primary method for transporting long rails in my country.

[0003] At present, there are two main methods for loading and reinforcing 25m rails for flat car coupling transportation in my country: one is to use two flat cars with two-point support for straddling. A rail support bogie is placed in the middle of each straddle-loaded flat car, and the rails and bogies are fixed together so that the two bogies bear the weight of the loaded rails. This method will cause excessive pressure on the middle of the flat car body, which will lead to weight concentration and damage the vehicle. Therefore, in the actual transportation of 25m rails, the two-point support straddle-load transportation method is no longer used. The second method is to use two flat cars with six-point support for straddling. In addition to placing a rail support bogie in the center of the two flat cars, a fixed support is placed on each of the two flat cars' sleepers (a total of four). The weight of the loaded rails is distributed on six points, avoiding the weight concentration phenomenon that occurs in two-point straddle-load transportation. Six-point straddle loading is the main solution currently used in my country to transport 25m of rails using two flat cars. However, when the vehicle passes through a curve, the resistance generated by the rails and the fixed support produces a certain lateral force on the vehicle, resulting in lateral displacement, which can easily cause vehicle transportation accidents. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a rotatable structural rail transport support device to solve the problem that when two flat cars are used to transport 25m of rails, the rails exert a certain lateral force on the vehicle, resulting in lateral displacement and easily causing vehicle transportation accidents when the vehicle passes through a curve.

[0034] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0035] like Figure 1-4As shown, a rotatable structural rail transport support device comprises:

[0036] Pad 1, set on the car plate of the flat car;

[0037] The lower end of the movable bracket 2 is detachably and rotatably connected to the pad 1, and the upper end is provided with a sleeper 3 and a lifting shaft 4.

[0038] Specifically, the rotatable structural rail transport support device is fixed on the vehicle plate by connecting the pad 1 with the vehicle plate, and the fixed rail is supported by the movable bracket 2, so that the rail and the vehicle plate can rotate relative to each other, and then when the vehicle passes through the rotatable structural rail transport support device when turning, the rail and the vehicle plate form an angle, avoiding the bending force of the steel structure and transmitting the bending force to the vehicle, which makes the vehicle unstable and dangerous when turning. The sleepers 3 are convenient for fixing the rails, and the lifting shaft 4 can lift the movable bracket, which can be loaded and unloaded separately by the movable bracket 2, and can also be loaded and unloaded together with the movable bracket 2 and the rail fixed on the movable bracket 2.

[0039] Furthermore, the sleeper 3 has a lower hardness than the rail, which can prevent the rail from being worn when sliding friction occurs.

[0040] In this embodiment, the pad 1 includes a plate body, on which a rotating shaft 5 is provided. The movable bracket 2 includes a frame body, and the lower end of the frame body is provided with a rotating sleeve 6 and multiple rollers 7 that cooperate with the rotating shaft 5. The multiple rollers 7 are distributed at intervals on both sides of the rotating sleeve 6.

[0041] Specifically, the relative rotation of the pad 1 and the floating bracket 2 is achieved by the cooperation between the rotating shaft 5 and the rotating sleeve 6, and the plug-in cooperation between the rotating shaft 5 and the rotating sleeve 6 also facilitates the disassembly, separation and assembly of the pad 1 and the floating bracket 2. At the same time, the roller 7 supports the rotation of the floating bracket 2 and the auxiliary floating bracket 2.

[0042] Furthermore, the roller 7 includes two vertical plates, which are arranged at the lower end of the frame at an interval, a wheel body is arranged between the two vertical plates, and a wheel axle is axially passed through the wheel body, and both ends of the wheel axle are respectively connected to the two vertical plates.

[0043] In this embodiment, fixing mechanisms are provided at both ends of the pad 1, and the fixing mechanisms include:

[0044] A plurality of ribs 8 are arranged on the plate body at intervals, and a wire hole is provided on the ribs 8;

[0045] The side beam 9 is provided at the upper ends of the plurality of rib plates 8 , and one end thereof away from the rotation axis 5 is connected to the end of the plate body.

[0046] Specifically, the pad 1 is fixed with a rail, and the rail can be wound and fixed on the sleeper 3 and can also be connected and fixed through the wire holes. At the same time, the side beam 9 improves the stability of the multiple ribs 8 and ensures the connection strength of the wire holes.

[0047] In this embodiment, it also includes:

[0048] The fixing clip 10 is U-shaped, with one inner wall connected to the side beam 9 and the other inner wall connected to the lower end surface of the vehicle plate;

[0049] The fastening bolt 11 has one end threaded through the fixing clamp 10 and then squeezes the upper end surface of the side beam 9.

[0050] Specifically, the backing plate 1 is fixed to the vehicle plate by a fixing clip 10 , and the fixing clip 10 is ensured to be stably connected by tightening bolts 11 .

[0051] In this embodiment, the upper end of the frame is provided with an embedding groove that matches the sleeper 3, the embedding groove is provided with a water leakage hole 12, and the two ends of the embedding groove are respectively provided with a lifting shaft 4.

[0052] Specifically, the sleepers 3 are fixed by embedding the grooves to prevent the sleepers 3 from slipping off the frame, and the water leakage holes 12 prevent the accumulated water from soaking and corroding the sleepers 3.

[0053] In this embodiment, the floating bracket 2 is located on the center line of the base plate 1 , and the width of the base plate 1 is greater than the width of the floating bracket 2 .

[0054] Specifically, the traveling bracket 2 rotates on the pad 1 to avoid the upper end surface friction of the vehicle plate hindering the rotation. In this embodiment, the upper end of the sleeper 3 is exposed in the embedding groove and is lower than the lifting shaft 4.

[0055] Specifically, it prevents the rails from contacting and abrading each other with the frame, and at the same time, the lifting shaft 4 can also assist in restraining the rails to prevent them from slipping.

[0056] In this embodiment, a damping and limiting mechanism is provided between the backing plate 1 and the movable bracket 2 , which can enable the backing plate 1 and the movable bracket 2 to form any angle.

[0057] Specifically, the relative angle between the pad 1 and the movable bracket 2 is maintained by a damping limit mechanism or other locking mechanism to prevent the two from rotating and shaking at will. At the same time, the movable bracket 2 can be made to coincide with the vehicle axis when the rails are not being transported, so that it can be adapted to other loads without disassembly, avoiding interference with the transportation of other items.

[0058] Furthermore, a damping layer is provided on the inner periphery of the rotating sleeve 6 or the outer periphery of the rotating shaft 5 .

[0059] like Figure 5 As shown, the present invention also provides a railway freight car, comprising:

[0060] The above-mentioned rotatable structural rail transport support device.

[0061] In this embodiment, it also includes:

[0062] Two car plates, with rotatable structural rail transport support devices respectively arranged at the middle and both ends of the car plates.

[0063] Specifically, by setting up a total of six rotatable structural rail transportation support devices, it is ensured that the rails are subjected to balanced force and no weight is concentrated, and the force direction of the rails is prevented from interfering with the flat car's turning when turning.

[0064] When a rotatable structural rail transport support device of the present embodiment is used, taking the use of a railway freight car carrying 25m of rails as an example, two flat cars are connected, and a rotatable structural rail transport support device is respectively set at the middle and both ends of the two flat cars (a total of six), and then the 25m rails are placed on the six rotatable structural rail transport support devices. When the vehicle turns, the rotatable structural rail transport support device rotates according to the size of the turn, so that the 25m rails do not need to rotate with the flat car or rotate at a smaller angle relative to the flat car, thereby reducing the lateral force exerted by the 25m rails on the flat car when turning, ensuring smooth and safe turning.

[0065] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
