Description

Technical Field

[0001] The utility model relates to the field of railways, in particular to an anti-overturning device for rails during stress relaxation of seamless lines of suburban railways. Background Technique

[0002] In long track lines, after the rails are locked, they cannot freely expand and contract due to temperature effects. When the rail temperature is different from the locked rail temperature, corresponding temperature stresses will be generated in the track. As the temperature difference increases, the stress will also increase accordingly. To keep the temperature stress within the control range and avoid damage to the rail strength and line stability, measures such as regularly loosening the splints and fasteners are usually taken to release the stress. This operation process is called stress relaxation. Equipment such as rail bumpers will be used during stress relaxation. The rail bumper is mainly used when welding jointless joints of long railway rails and during stress relaxation of jointless lines. A "rail manual pulley" is used to impact the rail bumper to make the long rail move longitudinally and adjust the rail gap operation.

[0003] The rail anti-overturning device mainly uses the combination of sleepers and fasteners. Before stress relaxation of the rails in the jointless line, installing this device can provide a certain degree of protection for the rails and prevent the rails from overturning and injuring people.

[0004] After retrieval, the Chinese patent publication number: CN218291465U discloses a rail anti-overturning device, including a rail body and a connecting rod. The number of rail bodies is two. The surfaces of the two rail bodies are both rotatably connected with a first bearing. A first fixing column is fixedly connected inside the first bearing. A second fixing column is inserted on the surface of the first fixing column. The bottom of the surface of the second fixing column is fixedly connected with a second bearing, and the top of the second fixing column is fixedly connected with a first disc. For this rail anti-overturning device, through the settings of the first bearing, the second bearing, the U-shaped plate and the connecting rod, when in use, the device is carried to the railway track, the U-shaped plate is covered on the track, the first bearing and the second bearing are respectively aligned with the surface and side of the railway track in sequence, and the two sides of the railway track are connected and fixed through the connecting rod, so that while not affecting the movement of the rail, it can ensure that the rail always remains standing and is convenient for timely movement.

[0005] Although the above device can protect the rail, it is directly installed on the upper part of the rail and is not connected to the ground. This leads to insufficiently firm support and protection for the rail. When one side of the rail tilts, it is extremely easy to drive the device on its upper part to tilt together. During this process, it is also easy to pull the rail on the other side, which is likely to cause injury to personnel and damage to the device, and it is not practical enough. Therefore, an anti-overturning device for rails during stress relaxation of seamless lines of suburban railways is proposed to solve the above problems. Content of the Utility Model

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: A kind of anti-overturning device for stress relaxation of seamless rails in urban rail transit, including a rail body 1, a plurality of sleepers 2 are installed under the rail body 1, which are railway fittings for supporting the rail. An anti-overturning component 3 is arranged on the upper part of the sleeper 2 for use during stress relaxation of the rail. A fastener 4 is movably connected to the upper part of the sleeper 2 through bolts for fixing the rail, and it needs to be loosened during stress relaxation. Limiting components 5 are arranged on the left and right parts of the anti-overturning component 3 for limiting the rail to prevent it from tipping during stress relaxation.

[0035] Please refer to Figure 4 - Figure 6 , the anti-overturning component 3 includes an outer shell 31 for connecting each component. Vertical plates 33 are movably connected to the left and right sides of the outer shell 31 for supporting each component and for protecting the rail. An adjusting component 32 is arranged in the middle of the outer shell 31 for adjusting the distance between the two vertical plates 33. The bottom of the vertical plate 33 is fixedly connected with a mounting plate 34 for being fixed to the sleeper 2 through bolts. The holes in its upper part are consistent with the holes in the fastener 4, so that it can be bolted to the fastener 4.

[0036] Further, the adjusting component 32 includes a first bevel gear 321 for driving two second bevel gears 323 to rotate. A rotating rod 322 is fixedly connected to the middle of the first bevel gear 321 for driving the first bevel gear 321 to rotate. The rotating rod 322 penetrates through the upper part of the housing 31 and is rotatably connected thereto. The lower part of the first bevel gear 321 is meshed with a second bevel gear 323 on both the left and right sides for driving a screw rod 324 to rotate. A screw rod 324 is fixedly connected to the middle of the second bevel gear 323 for adjusting the distance between the vertical plate 33 and the housing 31 through a connecting rod 331 to adapt to different steel rails, so that the mounting plate 34 can be matched with the bolt positions of different fasteners 4 for installation.

[0037] Furthermore, a connecting rod 331 is fixedly connected to one side of the upper part of the vertical plate 33 close to the housing 31. It is a cuboid rod for connecting with the screw rod 324. The screw rod 324 penetrates through the connecting rod 331 and is threadedly connected thereto. An adjusting opening 332 is formed in the middle of the vertical plate 33 for cooperating with the connection of the limiting component 5 to cooperate with the position adjustment of the limiting component 5. Auxiliary openings 333 are formed in both the left and right parts of the vertical plate 33 for cooperating with the connection and movement of the limiting rod 511.

[0038] Specifically, an installation cavity 311 is formed in the middle of the housing 31 for cooperating with the installation of the adjusting component 32. Connecting grooves 312 are formed on both the left and right sides of the installation cavity 311 for cooperating with the connection of the connecting rod 331, and the connecting rod 331 is slidably connected thereto.

[0039] As Figure 3 shown, the limiting component 5 further includes a mounting frame 51 for connecting each component. A plurality of rollers 52 are rotatably connected to the inner wall of the mounting frame 51 for limiting the steel rail body 1 and at the same time can cooperate with the movement of the steel rail body 1 during rail impact. A stud 53 is rotatably connected to one side of the mounting frame 51 close to the vertical plate 33 for adjusting the position of the mounting frame 51 with the roller 52. A limiting member 55 is arranged outside the stud 53 for cooperating with the movement and limitation of the position of the limiting component 5. The limiting member 55 includes an empty tube 551 for connecting each component. The empty tube 551 is slidably connected to the adjusting opening 332. The stud 53 is threadedly connected to the empty tube 551. A fixing ring 552 is fixedly connected to one end of the empty tube 551 close to the mounting frame 51, which can prevent the empty tube 551 from passing through the adjusting opening 332. A limiting ring 553 is threadedly connected to one side of the empty tube 551 away from the fixing ring 552 for cooperating with the fixing ring 552 to clamp the left and right sides of the vertical plate 33, thereby fixing the position of the empty tube 551. Limiting rods 511 are fixedly connected to both the front and rear parts of one side of the mounting frame 51 close to the stud 53 for limiting the moving direction of the mounting frame 51. The limiting rods 511 are slidably connected to the auxiliary openings 333.

[0040] Working principle: When in use, first, according to the width of the rail body 1, rotate the rotating rod 322 to drive the first bevel gear 321 to rotate. The two second bevel gears 323 meshing with the first bevel gear 321 will be driven to rotate accordingly, thereby driving the screw rod 324 connected thereto to rotate. When the screw rod 324 rotates, according to its rotation direction, it will drive the connecting rod 331 connected thereto to slide in the connecting groove 312, so as to adjust the distance between the vertical plate 33 and the housing 31, making the mounting plate 34 of the anti-overturning assembly 3 better fixed to the sleeper 2. When stress relaxation is required, the fasteners 4 on both sides of the rail need to be loosened, then select one of the sleepers 2 under the rail, remove the fastener 4 on its upper part, then fix the mounting plate 34 of the anti-overturning assembly 3 to the sleeper 2 with bolts, and then adjust the position of the limiting assembly 5 according to the shape of the rail body 1. First, rotate the limiting ring 553 to make it away from the fixed ring 552, so that there is a certain gap between the fixed ring 552 and the limiting ring 553 and the vertical plate 33, enabling the hollow tube 551 to slide in the adjustment port 332, thereby adjusting the position of the limiting assembly 5. When adjusted to the appropriate position, rotate the limiting ring 553 in the reverse direction to cooperate with the fixed ring 552 to clamp the vertical plate 33, thus fixing the position of the limiting assembly 5. Then rotate the stud 53 to drive the mounting frame 51 and the roller 52 connected thereto to move until the roller 52 abuts against both sides of the rail. When the rail impact operation is performed and the position of the rail moves, the roller 52 will assist the rail to move. After the stress relaxation is completed, separate the anti-overturning assembly 3 from the sleeper 2, and then install and fix the fastener 4.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
