Description

Technical Field

[0001] This invention relates to the field of rail transport vehicle technology, specifically to an anti-tipping beam structure and an anti-tipping mechanism. Background Technology

[0002] During the transportation of long steel rails, T11BK type long rail transport train sets are used. The T11BK type long rail transport train sets have two types of anti-tipping mechanisms. The first type uses anti-tipping beams to prevent the first and second layers of rails from tipping over, while the second type uses anti-tipping beams to prevent the third and fourth layers of rails from tipping over. The anti-tipping beams in the T11BK type long rail transport train sets consist of steel beams, anti-tipping rollers, and stop pins. Steel sleeves at the ends of the steel beams are connected to side posts via rotating shafts, allowing the anti-tipping beams to rotate horizontally. Each anti-tipping beam consists of 13 anti-tipping rollers, each connected to the steel beam by three bolts. Each anti-tipping roller has two stop pins above it to prevent it from jumping upwards. Before use, each layer of anti-tipping beams requires the removal of the stop pins (26 in total) and the anti-tipping rollers (13 in total).

[0003] The anti-tipping beams of the existing T11BK long rail transport train sets are large and heavy, making them difficult to open and close. In addition, each opening and closing requires disassembling the anti-tipping rollers and their corresponding stop pins, which is a cumbersome process. Furthermore, the existing T11BK long rail transport train sets can only prevent the tipping of two layers of rails per train, which cannot meet the technical requirement of preventing the tipping of four layers of rails per train. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-rollover beam structure and an anti-rollover device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-tipping beam structure, comprising an anti-tipping beam body, a rotating bushing provided at the right end of the anti-tipping beam body, a plurality of anti-tipping rollers rotatably connected to the lower part of the anti-tipping beam body, a positioning slider provided between each pair of anti-tipping rollers, a plurality of first insertion holes opened on the surface of the anti-tipping beam body, a second insertion hole opened on the surface of the anti-tipping beam body between the first insertion holes, a sliding rod slidably connected inside the second insertion hole, a connecting block fixedly connected to the lower end of the sliding rod, and the lower end of the connecting block rotatably connected to the positioning slider.

[0006] By adopting the above technical solution, during the rail loading operation, the anti-tipping beam body is manually pushed open. After one layer of rails is loaded, the anti-tipping beam body is rotated 90° so that the anti-tipping rollers are parallel to the rails. At the same time, the anti-tipping beam body is pushed to close it in the initial position. Then, the anti-tipping beam body is rotated back so that the anti-tipping rollers are perpendicular to the rails and separate them. During the flipping process of the anti-tipping beam body, the positioning slider will contact the upper surface of the rails. As the rotation continues, the positioning slider will push the sliding rod upward, causing it to slide upward inside the second insertion hole and compress the positioning spring. When the anti-tipping rollers are perpendicular to the rails, the positioning slider is perpendicular to the upper surface of the rails. Under the pressure of the positioning spring, the rails are clamped and fixed, improving the stability of the rails during transport. Finally, the pin at the end is inserted to lock the anti-tipping beam body. The positioning slider and the anti-tipping rollers on both sides cooperate to improve the stability of the rails and increase transport safety.

[0007] Optionally, a first limiting block is fixedly connected to the surface of the slide rod near the lower position, the lower surface of the first limiting block abuts against the inner bottom wall of the anti-tipping beam body, and a second limiting block is fixedly connected to the surface of the slide rod near the upper position, the second limiting block abuts against the upper surface of the anti-tipping beam body.

[0008] Optionally, a positioning spring is fitted on the surface of the slide rod inside the anti-tipping beam body. The upper end of the positioning spring is fixedly connected to the inner top wall of the anti-tipping beam body, and the lower end of the positioning spring is fixedly connected to the upper surface of the first limiting block.

[0009] By adopting the above technical solution, after the anti-tipping beam body is installed, the positioning spring pushes the first limit block downward, which in turn pushes the positioning slider downward to clamp and fix the rail, together with the anti-tipping roller, thereby improving the stability of rail transportation.

[0010] Optionally, the inner wall of the anti-tipping roller is fixedly connected with two sets of third rotating rings, and the inner side of the third rotating ring is rotatably connected with a roller shaft. The roller shaft is inserted and fixedly connected to the first insertion hole, and the bottom end of the anti-tipping roller is fixedly connected with a retaining ring.

[0011] Optionally, an end cap is fixedly connected to the left end of the anti-tipping beam body, and a first connecting sleeve is fixedly connected to the right end of the anti-tipping beam body.

[0012] Optionally, a rotating shaft is fixedly connected to the right side surface of the rotating bushing, a shaft cover is fixedly connected to the surface of the rotating bushing, a reinforcing block is fixedly connected inside the shaft cover, the reinforcing block is snapped and fixed to the rotating shaft, and a shaft seal is fixedly connected to the left side surface of the shaft cover.

[0013] Optionally, a second connecting sleeve is sleeved on the surface of the rotating shaft, and two sets of first rotating rings are fixedly connected to the inner wall of the second connecting sleeve. The first rotating rings are rotatably connected to the rotating shaft, and the left end of the second connecting sleeve is fixedly connected to the right end of the first connecting sleeve.

[0014] Optionally, a second rotating ring is fixedly connected inside the rotating bushing, and a shaft seat is rotatably connected inside the second rotating ring. A positioning cover plate is sleeved and connected to the upper end of the shaft seat.

[0015] By adopting the above technical solution, during the installation of the rails, the anti-tipping beam body is rotated 90° clockwise around the axis of rotation. At this time, the right end of the anti-tipping beam body drives the second connecting sleeve to rotate 90° clockwise around the axis of rotation, turning the anti-tipping rollers to a horizontal position. Then, the anti-tipping beam body is rotated 90° clockwise around the axle seat, turning the anti-tipping beam body to the side. Next, the rails are assembled. After the rails are assembled, the anti-tipping beam body is rotated 90° counterclockwise around the axle seat, and then rotated 90° counterclockwise around the axis of rotation to divide the rails, thus playing an anti-tipping role. During use, the anti-tipping beam body simultaneously drives multiple sets of anti-tipping rollers and positioning sliders for adjustment, reducing the need to disassemble and reassemble the anti-tipping rollers during operation, and also reducing the resistance when the anti-tipping beam is opened and closed, greatly reducing labor intensity and improving work efficiency.

[0016] Optionally, the vehicle body includes a transport vehicle body, characterized in that two sets of fixed brackets are fixedly connected to the lower surface of the transport vehicle body, four sets of rotating rollers are rotatably connected to the outer side of the fixed brackets, two sets of first support columns are fixedly connected to both the front and rear ends of the transport vehicle body, and several sets of mounting brackets are fixedly connected to the upper surface of the transport vehicle body.

[0017] By adopting the above technical solution, multiple sets of rotating rollers drive the transport vehicle to move and transport the steel rails.

[0018] Optionally, a support beam is fixedly connected between the first support columns at both ends, and a second support column is fixedly connected between the support beam and the transport vehicle body. The anti-tipping beam body is set between the two sets of second support columns on the left and right sides. The upper end of the positioning cover plate and the lower end of the axle seat are both fixedly connected to the second support column on the right side, and the end cover is rotatably connected to the second support column on the right side.

[0019] By adopting the above technical solution, four sets of anti-rollover beam bodies are set between the two sets of second support columns. The four sets of anti-rollover beam bodies prevent the four layers of rails from overturning, which greatly improves the performance of the vehicle. The mounting bracket is used to assemble multiple sets of rails. At this time, the anti-rollover beam bodies fix multiple sets of rails to prevent them from overturning.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The anti-tipping beam structure and anti-tipping mechanism have a second insertion hole on the surface of the anti-tipping beam body between the first insertion holes. A sliding rod is slidably connected inside the second insertion hole. A connecting block is fixedly connected to the lower end of the sliding rod. The lower end of the connecting block is rotatably connected to the positioning slider. During the process of limiting the position of the left and right sides of the rail, the positioning slider clamps and fixes the upper surface of the rail. The positioning slider cooperates with the anti-tipping rollers on both sides to improve the stability of the rail and increase transportation safety.

[0022] 2. This anti-tipping beam structure and anti-tipping vehicle features a rotating bushing at the right end of the anti-tipping beam body. Multiple sets of anti-tipping rollers are rotatably connected to the lower part of the anti-tipping beam body. Positioning sliders are installed between each set of anti-tipping rollers. During use, the positions of the anti-tipping rollers and positioning sliders are adjusted by flipping and rotating the anti-tipping beam body, thus positioning the rail and preventing it from tipping over. This reduces the need to disassemble and reassemble the anti-tipping rollers during operation and also reduces resistance when opening and closing the anti-tipping beam, significantly reducing labor intensity and improving operational efficiency. It solves the problem of the existing T11BK type long rail transport vehicle's anti-tipping beam being large and heavy, requiring considerable effort to open and close, and necessitating the disassembly of the anti-tipping rollers and their corresponding stop pins each time it is opened or closed, resulting in a cumbersome process.

[0023] 3. The anti-rollover beam structure and anti-rollover vehicle, by setting the anti-rollover beam body between the two sets of second support columns on the left and right, and setting four sets of anti-rollover beams to install four layers of anti-rollover beams to prevent the four layers of rails from overturning, greatly improves the performance of the vehicle and solves the problem that the existing T11BK type long rail transport vehicle can only prevent the overturning of two layers of rails per vehicle, and cannot meet the technical requirement of preventing the overturning of four layers of rails by one vehicle.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 6This invention provides an anti-tipping beam structure, including an anti-tipping beam body 2. A rotating bushing 3 is provided at the right end of the anti-tipping beam body 2. Multiple sets of anti-tipping rollers 4 are rotatably connected to the lower part of the anti-tipping beam body 2. A positioning slider 27 is provided between each set of anti-tipping rollers 4. Multiple sets of first insertion holes 23 are formed on the surface of the anti-tipping beam body 2. Second insertion holes 24 are formed on the surface of the anti-tipping beam body 2 between the first insertion holes 23. A sliding rod 25 is slidably connected inside the second insertion hole 24. A connecting block 26 is fixedly connected to the lower end of the sliding rod 25. The lower end of the connecting block 26 is connected to the positioning slider. 27. A first limiting block 28 is fixedly connected to the surface of the slide rod 25 near the lower position. The lower surface of the first limiting block 28 abuts against the inner bottom wall of the anti-rollover beam body 2. A second limiting block 210 is fixedly connected to the surface of the slide rod 25 near the upper position. The second limiting block 210 abuts against the upper surface of the anti-rollover beam body 2. A positioning spring 29 is sleeved on the surface of the slide rod 25 inside the anti-rollover beam body 2. The upper end of the positioning spring 29 is fixedly connected to the inner top wall of the anti-rollover beam body 2, and the lower end of the positioning spring 29 is fixedly connected to the upper surface of the first limiting block 28.

[0035] During the rail loading operation, the pin at the end of the anti-rollover beam body 2 is pulled out, and the anti-rollover beam body 2 is pushed open by hand. After one layer of rails is loaded, the anti-rollover beam body 2 is rotated 90° so that the anti-rollover roller 4 is parallel to the rails. At the same time, the anti-rollover beam body 2 is pushed to close it in the initial position. Then, the anti-rollover beam body 2 is rotated back so that the anti-rollover roller 4 is perpendicular to the rails and separates them. During the flipping process of the anti-rollover beam body 2, the positioning slider 27 will contact the upper surface of the rails. During the continued rotation, the positioning slider 27 will push the slide rod 25 upward, causing it to slide upward inside the second insertion hole 24 and compress the positioning spring 29. When the anti-rollover roller 4 is perpendicular to the rails, the positioning slider 27 is perpendicular to the upper surface of the rails. Under the pressure of the positioning spring 29, the rails are clamped and fixed, improving the stability of the rail transport. Finally, the pin at the end is inserted to lock the anti-rollover beam body 2.

[0036] See Figure 5 The inner wall of the anti-rollover roller 4 is fixedly connected with two sets of third rotating rings 42. The inner side of the third rotating ring 42 is rotatably connected with a roller shaft 41. The roller shaft 41 is inserted and fixedly connected to the first insertion hole 23. The bottom end of the anti-rollover roller 4 is fixedly connected with a retaining ring 43. The left end of the anti-rollover beam body 2 is fixedly connected with an end cap 21. The right end of the anti-rollover beam body 2 is fixedly connected with a first connecting sleeve 22.

[0037] Specifically, the anti-tipping roller 4 separates multiple sets of rails, and multiple sets of anti-tipping roller 4 can be adjusted simultaneously to improve work efficiency.

[0038] See Figure 2 and Figure 3 A rotating shaft 31 is fixedly connected to the right side surface of the rotating bushing 3. A shaft cover 32 is fixedly connected to the surface of the rotating bushing 3. A reinforcing block 33 is fixedly connected inside the shaft cover 32. The reinforcing block 33 is snapped and fixed to the rotating shaft 31. A shaft seal 34 is fixedly connected to the left side surface of the shaft cover 32. A second connecting sleeve 35 is sleeved and connected to the surface of the rotating shaft 31. Two sets of first rotating rings 36 are fixedly connected to the inner wall of the second connecting sleeve 35. The first rotating rings 36 are rotatably connected to the rotating shaft 31. The left end of the second connecting sleeve 35 is fixedly connected to the right end of the first connecting sleeve 22. A second rotating ring 37 is fixedly connected inside the rotating bushing 3. A shaft seat 38 is rotatably connected inside the second rotating ring 37. A positioning cover plate 39 is sleeved and connected to the upper end of the shaft seat 38.

[0039] During the installation of the rails, the anti-tipping beam body 2 is rotated 90° clockwise around the axis of the rotating shaft 31. At this time, the right end of the anti-tipping beam body 2 drives the second connecting sleeve 35 to rotate 90° clockwise around the rotating shaft 31, rotating the anti-tipping roller 4 to a horizontal position. Then, the anti-tipping beam body 2 is rotated 90° clockwise around the axle seat 38, rotating the anti-tipping beam body 2 to the side. Then, the rails are assembled. After the rails are assembled, the anti-tipping beam body 2 is rotated 90° counterclockwise around the axle seat 38, and then rotated 90° counterclockwise around the axis of the rotating shaft 31 to divide the rails and simultaneously prevent them from tipping over.

[0040] See Figure 7 and Figure 8 This invention provides an anti-rollover system, comprising a transport vehicle body 1. The system is characterized in that two sets of fixed brackets 11 are fixedly connected to the lower surface of the transport vehicle body 1, and four sets of rotating rollers 12 are rotatably connected to the outer side of each fixed bracket 11. Two sets of first support columns 13 are fixedly connected to both the front and rear ends of the transport vehicle body 1. Several sets of mounting brackets 15 are fixedly connected to the upper surface of the transport vehicle body 1. A support beam 14 is fixedly connected between the first support columns 13 at both the front and rear ends. A second support column 16 is fixedly connected between the support beam 14 and the transport vehicle body 1. An anti-rollover beam body 2 is positioned between the left and right sets of the second support columns 16. The upper end of the positioning cover plate 39 and the lower end of the axle seat 38 are both fixedly connected to the right second support column 16. The end cap 21 is rotatably connected to the right second support column 16.

[0041] It should be added that four sets of anti-rollover beam bodies 2 are installed between the two sets of second support columns 16. The four sets of anti-rollover beam bodies 2 prevent the four layers of rails from overturning, which greatly improves the performance of the vehicle. The mounting bracket 15 is used to assemble multiple sets of rails. At this time, the anti-rollover beam bodies 2 fix multiple sets of rails to prevent them from overturning.

[0042] Working principle: In order to reduce labor intensity, improve work efficiency and enhance vehicle performance, the workers install four sets of anti-rollover beam bodies 2 between the two sets of second support columns 16. The four sets of anti-rollover beam bodies 2 and the four layers of steel rails are tilted, which greatly improves the performance of the vehicle. Furthermore, by flipping and rotating the anti-rollover beam bodies 2, the position of the anti-rollover rollers 4 and the positioning sliders 27 is adjusted to position the steel rails and prevent them from tilting.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
