Description

Technical Field

[0001] The utility model belongs to the technical field of railway construction, and in particular relates to a railway turnout reinforcement device. Background Art

[0002] A turnout is a connecting device that allows rolling stock to transfer from one track to another. It's also a weak link in track construction and is typically installed in large numbers at stations and marshalling yards. Turnouts maximize the capacity of a line. Even on a single-track railway, laying a turnout and constructing a fork line longer than the length of the train allows trains to run in opposite directions. Turnouts play a vital role on railway lines.

[0003] In the prior art, the method for reinforcing railway turnouts is usually to cross-connect the longitudinal beam on the rail clip and the track crossbeam and fix them with two U-bolts; as the spacing between the straight and curved rails in the turnout becomes smaller, the rail clip at the center of the track is reinforced and extended according to the spacing between the rail bottom pads, and the number of rail clips decreases in sequence from seven-clip rails to five-clip rails, three-clip rails, and one-clip rails, until the one-clip rail is no longer intrusive. However, in this reinforcement method, the rail clip is an I-beam standing on the track crossbeam. When installing the rail clip, there will be a situation where there is only one fixed position between a section of the rail clip and the track crossbeam. Since the reinforcement effect of the rail clip and the track crossbeam depends on the U-bolts on the track crossbeam, when there is only one reinforcement position, the overall reinforcement effect of the U-bolt is poor. When the U-bolt is loose, it is easy to cause the rail clip to slide, affecting the reinforcement strength between the rail clip and the track crossbeam, and posing a great risk to the operation of locomotives and vehicles.

[0024] Please also refer to Figures 1 to 5 The railway turnout reinforcement device provided by the present invention is now described. The railway turnout reinforcement device includes a base 10, a clamping assembly 20 and a fastening assembly 30; the base 10 is located below the track beam 40, and is provided with two first cavities 11 on the base 10, and the first rails 12 are horizontally provided in the two first cavities 11; the clamping assembly 20 is provided on the base 10, and the clamping assembly 20 has two clamping ends, which are respectively located in the two first cavities 11 and are both slidably connected to the first rails 12, and the two clamping ends are used to clamp on the track beam 40 and cooperate with each other to clamp the upper longitudinal beam 50 of the buckle rail, and the clamping ends are provided with claws 21, which are used to clamp the bottom flange of the upper longitudinal beam 50 of the buckle rail; the fastening assembly 30 is provided above the clamping assembly 20, and the fastening assembly 30 has a plurality of fasteners 31, which are used to abut the upper surface of the upper longitudinal beam 50 of the buckle rail.

[0025] It should be noted that the upper longitudinal beam 50 of the rail clip is an I-beam, the abutment position of the claw 21 is located on the upper surface of the flange of the I-beam at the bottom, and the fastening position of the fastener 31 is the upper top surface of the I-beam; the track beam 40 is placed above the ground. When reinforcing the railway turnout, a space suitable for the base 10 to enter needs to be dug on the ground below the track beam 40, and the base 10 is placed under the track beam 40 so that the clamping assembly 20 presses against the lower surface of the track beam 40. The two clamping ends clamp the track beam 40 and are slidably connected to the first rails 12 in the two first cavities 11. The first rails 12 horizontally arranged in the first cavity 11 can limit the vertical movement of the clamping assembly 20, prevent the clamping assembly 20 from sliding out of the first cavity 11, and at the same time reduce the rotational movement of the two clamping ends in the vertical direction, so that the two clamping ends are When clamped on the track beam 40, it always remains in a vertical state, which can prevent the track-clamping longitudinal beam 50 from tilting between the two clamping ends, thereby improving the stability of the track-clamping longitudinal beam 50; the two clamping ends cooperate to clamp the two sides of the track-clamping longitudinal beam 50, the claws 21 abut against the upper surface of the bottom flange of the track-clamping longitudinal beam 50, and the fasteners 31 abut against the upper surface of the top flange of the track-clamping longitudinal beam 50. By jointly fixing the bottom and top of the track-clamping longitudinal beam 50, the reinforcement effect can be further improved, and when one of the reinforcements has an abnormality, it can still effectively limit the fixed position of the track-clamping longitudinal beam 50, thereby improving the stability of the track-clamping longitudinal beam 50 and reducing the risk of vehicle operation; after fixing the track-clamping longitudinal beam 50 to the track beam 40, backfill the space dug on the ground below the track beam 40 to improve the stability of the track beam 40.

[0026] The beneficial effect of the railway turnout reinforcement device provided by the present invention is that: compared with the prior art, the clamping assembly 20 adopted by the present invention has two clamping ends, which can be clamped on the track cross beam 40, and the clamping end is provided with a clamping claw 21 for clamping the bottom flange of the buckle rail upper longitudinal beam 50, so that when the clamping end is fixed on the track cross beam 40, the bottom of the buckle rail upper longitudinal beam 50 is fixed to the upper surface of the track cross beam 40, and the fastening assembly 30 above the clamping assembly 20 presses against the upper surface of the buckle rail upper longitudinal beam 50, avoiding The rail-clip upper longitudinal beam 50 produces vertical displacement; compared with the conventional fixing method using U-bolts, the two clamping ends can be clamped on the track beam 40, avoiding misalignment between the clamping ends and the track beam 40, which causes the rail-clip upper longitudinal beam 50 to tilt, and the clamping assembly 20 cooperates with the fastening assembly 30 so that when the rail-clip upper longitudinal beam 50 is fixed on the track beam 40, the upper and lower flanges of the rail-clip upper longitudinal beam 50 are both subject to the limiting fastening effect of the device, the overall reinforcement effect is stronger, and the stability of the rail-clip upper longitudinal beam 50 is higher.

[0027] In one possible implementation, see Figure 1 and Figure 2The clamping assembly 20 includes two slides 22 and two groups of clamping members; the two slides 22 are respectively slidably connected to the two groups of first rails 12, and each slide 22 is provided with two second cavities 221, and each second cavity 221 is horizontally provided with a second rail 222; the two groups of clamping members are respectively provided on the two slides 22, and are both slidably connected to the second rails 222.

[0028] It should be noted that the two slides 22 are slidably connected to the horizontally arranged first rail 12, and the first rail 12 limits the vertical displacement of the slide 22, so that the two slides 22 always remain parallel to the setting direction of the track beam 40 during the sliding process, and the upper surfaces of the two slides 22 always abut against the lower surface of the track beam 40; the two groups of clamps are slidably connected to the horizontally arranged second rail 222 to prevent the two groups of clamps from rotating in the vertical direction. The first rail 12 and the second rail 222 cooperate with each other to limit the movement direction of the slide 22 and the clamp, so that the slide 22 and the clamp can only move in the horizontal direction, avoiding the shaking of the upper longitudinal beam 50 of the buckle rail due to the rotation of the clamp, which is beneficial to improve the stability of the upper longitudinal beam 50 of the buckle rail.

[0029] In one possible implementation, see Figure 2 A first threaded rod 13 is rotatably provided on the base 10 , and the first threaded rod 13 passes through the two first cavities 11 , and the threads in the two first cavities 11 have opposite rotation directions.

[0030] It should be noted that the first threaded rod 13 can have an operating position extending outside the base 10. After the base 10 is placed under the track beam 40, the two clamping ends are controlled to contract and clamp the upper longitudinal beam 50 of the track by rotating the first threaded rod 13, so that the upper longitudinal beam 50 of the track is fixed to the upper surface of the track beam 40.

[0031] In one possible implementation, see Figure 3 , both slide seats 22 are provided with a first through hole 223 suitable for the first threaded rod 13 to pass through, and the first through hole 223 is threadedly matched with the first threaded rod 13.

[0032] It should be noted that the two slides 22 are respectively located in the two first cavities 11. Since the first threaded rod 13 rotates in opposite directions in the two first cavities 11, the two slides 22 will move closer to or away from each other when the first threaded rod 13 rotates. The two slides 22 are controlled to move closer to each other by rotating the first threaded rod 13, so that the two clamping ends can clamp the sides of the longitudinal beam 50 on the buckle rail, and the claws 21 on the clamping ends can clamp the upper surface of the bottom flange of the longitudinal beam 50 on the buckle rail, thereby improving the overall reinforcement capability and strengthening the stability of the longitudinal beam 50 on the buckle rail; and the first threaded rod 13 can also play a role in limiting the slide 22. When the first threaded hole penetrates into the through hole, it can prevent the slide 22 from separating from the base 10, thereby improving the overall reinforcement capability.

[0033] In one possible implementation, see Figure 3 The clamping member includes two clamping plates 23, which are respectively slidably connected to two second rails 222 of one group to form one of the clamping ends, and claws 21 are provided on the two clamping plates 23.

[0034] It should be noted that the two clamps 23 are both connected to the second rail 222 and cooperate with each other to clamp on the rail crossbeam 40. The two clamping ends have a total of four clamps 23. The four clamps 23 are respectively located at the four angles formed by the intersection of the rail crossbeam 40 and the upper longitudinal beam 50 of the buckle rail. The clamps 23 are clamped on the rail crossbeam 40 and cooperate with each other to abut on both sides of the upper longitudinal beam 50 of the buckle rail. The claws 21 can abut on the upper surface of the bottom flange of the upper longitudinal beam 50 of the buckle rail when the clamps 23 cooperate with each other to abut on both sides of the upper longitudinal beam 50 of the buckle rail, thereby improving the overall reinforcement capability and strengthening the stability of the upper longitudinal beam 50 of the buckle rail.

[0035] In one possible implementation, see Figure 3 A second threaded rod 224 is rotatably provided on each of the two slides 22 . The second threaded rod 224 passes through the two second cavities 221 , and the threads in the two second cavities 221 have opposite rotation directions.

[0036] In one possible implementation, see Figure 3 Each clamping plate 23 is provided with a second through hole 231 through which the second threaded rod 224 passes, and the second through hole 231 is threadedly engaged with the second threaded rod 224.

[0037] It should be noted that the second threaded rod 224 controls the two splints 23 in the second cavities 221 to move closer to or away from each other by rotation, so that the splints 23 can be clamped on the track crossbeam 40, avoiding rotational offset between the splints 23 and causing shaking of the longitudinal beam 50 on the rail; the second threaded rod 224 can also limit the vertical movement of the splint 23 when passing through the second through hole 231, avoiding the splint 23 from sliding out of the slide 22, and cooperating with the second track 222 to limit the splint 23, so that the splint 23 always moves horizontally, thereby improving the overall reinforcement capability.

[0038] In one possible implementation, see Figure 3 The angle between the claw 21 and the plane is smaller than the inclination angle of the bottom flange of the longitudinal beam 50 on the buckle rail.

[0039] It should be noted that the claw 21 can be a steel plate obliquely welded on the clamping plate 23, and the welding angle of the claw 21 is smaller than the inclination angle of the bottom flange of the upper longitudinal beam 50 of the clip rail. When the clamping ends approach each other to clamp the two sides of the upper longitudinal beam 50 of the clip rail, the claws 21 on the two clamping ends also approach each other and squeeze the bottom flange of the upper longitudinal beam 50 of the clip rail under the claw 21. Since the angle between the claw 21 and the plane is small, the angle of the claw 21 squeezed by the upper longitudinal beam 50 of the clip rail becomes larger during the clamping process, and at the same time, it has a rebound force pointing to the bottom flange of the upper longitudinal beam 50 of the clip rail, which can increase the fixing force of the upper longitudinal beam 50 of the clip rail and improve the reinforcement effect of the upper longitudinal beam 50 of the clip rail and the track crossbeam 40.

[0040] In one possible implementation, see Figure 4 The fastening assembly 30 also includes a plurality of threaded columns 32, each of which is connected to the clamping assembly 20; the two ends of the fastener 31 are located on both sides of the upper longitudinal beam 50 of the buckle rail, and are respectively sleeved on two of the threaded columns 32, and the fastener 31 is provided with a clamping portion 312, which is used to clamp the top flange of the upper longitudinal beam 50 of the buckle rail.

[0041] It should be noted that each threaded column 32 is respectively provided on the upper surface of each clamping plate 23, and both ends of the fastener 31 can be passed through the threaded column 32, and the length of the clamping portion 312 in the center of the fastener 31 is equal to the width of the buckle rail upper longitudinal beam 50 fixed on the track crossbeam 40. The fastener 31 is clamped to the top flange of the buckle rail upper longitudinal beam 50 through the clamping portion 312, and can still provide reinforcement for the whole when the bottom fixation of the buckle rail upper longitudinal beam 50 fails, thereby improving the reinforcement capacity and enhancing the stability of the buckle rail upper longitudinal beam 50; and when the buckle rail is extended by 1 buckle according to the spacing of the rail bottom pad, if the model of the buckle rail upper longitudinal beam 50 changes, it is only necessary to replace the fastener 31 and adjust the relative positions of each clamping plate 23 to achieve the fixation of different models of buckle rail upper longitudinal beams 50, thereby improving construction efficiency.

[0042] In one possible implementation, see Figure 4 A limiting member 33 is provided on the threaded column 32 , and the limiting member 33 is threadedly engaged with the threaded column 32 and pressed against the upper surface of the fastener 31 .

[0043] It should be noted that the limiter 33 can be a nut with a washer, which is screwed into the threaded column 32 and makes the washer abut against the upper surface of the fastener 31, limiting the movement of the fastener 31 in the vertical direction, so that each fastener 31 can abut against the upper surface of the longitudinal beam 50 on the clip rail, thereby improving the overall reinforcement capability.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
