Description

Technical Field

[0001] The utility model belongs to the field of rail production equipment, and in particular relates to a rail overturning and anti-stuck steel device. Background Art

[0002] The full-length quenched rails produced in the cooling bed area must be transported by a fast steel transport vehicle to the full-length quenching front transport roller, and then turned over by the steel turning machine to the upright state before entering the full-length quenching unit. Figure 1 Since the fast steel transport vehicle uses a long-distance chain transmission method, the multiple chains are put on the machine at different times, and the elastic stress of the rails is released during the temperature drop during steel transportation. After the rails are transported to the full-length quenching transport roller, there are bending angles at the north and south ends. Figure 2 , Figure 3 , the maximum supporting width of the steel turning claw of the steel turning machine is limited, and the arc height difference between the middle section of the rail and the north and south ends is greater than 500mm. After rolling, the operator needs to manually adjust the stop position of the fast steel transport vehicle for the first 1-3 rails so that the full length of the rail stops within the maximum supporting width of the steel turning claw of the steel turning machine. At present, there are 34 sets of steel turning machines, and the steel turning claws use L-shaped claws, such as: Patent application number: CN201822051681.0, which discloses a long rail lifting and turning device. Because the rolling rhythm affects the temperature of the rail, the curvature of the rail increases during transportation, and the rail end exceeds the range of the steel turning claw, causing the steel turning claw to scratch the surface of the rail during the turning process. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a rail flipping and anti-stuck steel device to reduce the scraping of steel during the flipping process caused by the curvature of the end of the transport rail exceeding the limit of the flipping claw, and avoid deep scratches on the rail surface caused by scraping.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A rail flipping and anti-stuck steel device comprises a steel flipping claw and a bracket. The steel flipping claw is a T-shaped platform, the steel flipping claw is fixedly connected to the bracket, the length of the steel flipping claw is greater than the bending chord height of the rail and less than the length of the full-length quenching transport roller; the steel flipping claw comprises a crossbeam and a fixed seat, the top of the crossbeam is a planar structure, the bottom of the crossbeam is welded to the fixed seat, and the fixed seat is fixedly connected to the bracket.

[0006] The upper surface of the steel turning claw is a plane structure.

[0007] The bracket is fixedly connected to the top of the steel turning machine.

[0008] The overturning and anti-jamming steel device is installed on the steel turning machines located at both ends.

[0009] When the steel turning machine is raised, the upper surface of the steel turning claw is higher than the upper surface of the fast steel transport car; when the steel turning machine is lowered, the upper surface of the steel turning claw is lower than the roller surface of the full-length quenching transport roller.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The turning claw of the rail turning and anti-stuck device adopts a T-shaped platform structure. When the turning machine with L-shaped turning claw is raised or lowered, it rises and falls with it. When the L-shaped turning claw turns the rail, it supports the rail and does not scrape the rail, thus reducing the time from stopping the transport rail to positioning and adjusting the turning machine.

[0012] 2. The rail turning and anti-stuck steel device is installed on the steel turning machines at both ends. It does not affect the normal rail transportation and steel turning operations, reduces the scraping of steel during the steel turning process caused by the curvature of the transport rail end exceeding the limit of the steel turning claw, and avoids deep scratches on the rail surface caused by scraping.

[0013] 3. The length of the steel turning claw is greater than the bending chord height of the rail and less than the length of the full-length quenching transport roller, ensuring that the rail will not fall off during the steel turning process, so that the full length of the rail stops within the maximum supporting width of the steel turning claw of the steel turning machine.

[0029] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0030] See Figure 4-Figure 7 The rail turning and anti-stuck steel device is installed on the steel turning machine 4 at the north and south ends. The rail turning and anti-stuck steel device includes a steel turning claw 5 and a bracket 6. The steel turning claw 5 is a T-shaped platform. The steel turning claw 5 is fixedly connected to the bracket 6. The length of the steel turning claw 5 is greater than the bending chord height of the rail 1 and less than the length of the full-length quenching transport roller 3.

[0031] See Figure 4-Figure 6 , the upper surface of the steel claw 5 is a flat structure. The steel claw 5 includes a crossbeam 51 and a fixing seat 52. The top of the crossbeam 51 is a flat structure. The bottom of the crossbeam 51 is welded to the fixing seat 52. The fixing seat 52 is fixedly connected to the bracket 6 by bolts. In the specific production, the crossbeam 51 is composed of two channel steels, the two channel steels are welded back to back, and the top is ensured to be a flat structure. The fixing seat 52 is composed of two channel steels, the two channel steels are arranged opposite to each other, and the top surface is welded to the bottom surface of the crossbeam 51.

[0032] The bracket 6 is fixedly connected to the top of the steel turning machine 4. The bracket 6 includes a bottom plate 61, a reinforcing plate 62, a column 63, and a positioning plate 64. The bottom plate 61 is provided with a plurality of mounting holes for fixedly connecting to the steel turning machine 4. A column 63 is welded to the bottom plate 61. The column 63 is composed of two channel steels. The spacing between the two channel steels matches the fixing seat 52. The fixing seat 52 is fixedly connected between the two channel steels. A positioning plate 64 is fixed between the bottoms of the two channel steels. A reinforcing plate 62 is welded between the column 63 and the bottom plate 61. A threaded hole may be provided on the top of the column 63. The column 63 is fixedly connected to the fixing seat 52 by bolts. To increase the firmness of the connection, a thickened pad may be welded on the column 63. The pad is provided with the same threaded hole as the top of the column 63.

[0033] There are 34 sets of steel turning machines 4 in the existing north-south direction. The two sets of steel turning machines 4 at both ends are modified, the original L-shaped steel turning claws 7 are removed, and the fixing seat 52 is welded on the bracket 6 of the original L-shaped steel turning claws 7, or the fixing seat 52 is fixedly connected with bolts, and the connecting rod 9 connected to the L-shaped steel turning claws 7 is removed to prevent the top end from scraping the steel. The turning hydraulic cylinder 8 and the transmission crank arm 10 on the steel turning machine 4 can be retained.

[0034] When the rail 1 is transported to the steel turning machine 4, 34 sets of steel turning machines 4 are raised at the same time. Figure 8 , Fig. 9 At this time, the steel turning machine 4 lifts up the rail 1, and then the L-shaped steel turning claws 7 of the middle 32 sets of steel turning machines 4 turn over, driving the rail 1 to turn over. Fig.10 , Fig.11 At this time, the steel turning claws 5 (T-shaped platforms) at both ends remain raised, and the upper surface of the steel turning claws 5 is higher than the upper surface of the fast steel transport vehicle 2. After the rail 1 is turned over, the bottom of the rail falls on the bottom surface of the L-shaped steel turning claws 7. Fig.12 The steel claws 5 at both ends remain stationary. Fig.13 After the curved parts of the rails 1 at the north and south ends are lifted up on the steel turning claws 5 (T-shaped platform), they can still be turned over smoothly, and the outer edge of the T-shaped platform will not be scratched during the turning process. After the rail 1 is turned over, all steel turning machines 4 are lowered, and the upper surface of the steel turning claws 5 is lower than the roller surface of the full-length quenching transport roller 3. The rail 1 falls back onto the roller surface. A guide plate is set at the transition connection between the roller and the next process unit to prevent the curved part of the rail 1 from hitting the roller or the next track.

[0035] The steel turning claw 5 of the utility model adopts a T-shaped platform structure. When the steel turning machine 4 with the L-shaped steel turning claw 7 is raised or lowered, it rises or lowers with it. When the L-shaped steel turning claw 7 performs the action of turning the rail 1, it plays the role of supporting the rail 1, and the steel scraping phenomenon will not occur, which reduces the time for the transportation rail 1 to stop at the steel turning machine 4 for positioning and adjustment. Only the steel turning machines 4 at both ends are modified to reduce the modification cost, and it is directly installed on the steel turning machines 4 at both ends, which does not affect the normal transportation and turning operation of the rail 1, and reduces the scraping of steel during the turning process caused by the bending degree of the end of the transportation rail 1 exceeding the limit of the steel turning claw, and avoids deep scratches on the surface of the rail 1 due to scraping. The length of the steel turning claw 5 is greater than the bending chord height of the rail 1, and less than the length of the full-length quenching transport roller 3, to ensure that the rail 1 will not fall off during the turning process, so that the full length of the rail 1 stops within the maximum supporting width range of the steel turning claw 5 of the steel turning machine 4.
