DETAILED DESCRIPTION

[0022] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0023] See also Figures 1-2 The utility model provides a single track turnout joint plate, comprising:

[0024] Joint plate assembly: The joint plate assembly includes a switch beam joint plate and a track beam joint plate. The switch beam joint plate 11 is arranged on the upper surface of the switch beam 1, and the track beam joint plate 21 is arranged on the upper surface of the track beam 2. The upper surfaces of the switch beam joint plate 11 and the track beam joint plate 21 are flush, and a gap 12 is provided between the adjacent end faces of the track beam joint plate 21 and the switch beam joint plate 11. The front end outer corners of the switch beam joint plate 11 and the track beam joint plate 21 are both provided with chamfers; the front end outer corners of the joint plate are designed to be large chamfers to avoid the joint plate from colliding when the turnout is switched. There are no pins, sleeves, or limit devices, which avoids problems such as the joint plate being stuck and warped, the limit block being broken, the fingertip being broken, and the copper sleeve being worn, thereby improving the reliability of the components and reducing the failure rate of the joint plate; the flat joint plate does not have the inspection and measurement work such as the sleeve gap, the limit device gap, and the fingertip overlap gap, thereby reducing the maintenance workload.

[0025] Support seat assembly: The support seat assembly includes a turnout support seat 3, which is L-shaped. One side panel of the turnout support seat 3 is fixed to the end face of the turnout beam 1, and the other side panel is fixed below the turnout beam joint plate 11. By providing the joint plate assembly and support seat assembly, the finger-like structure is reduced, solving the problem of breakage and wear at the finger ends of the original movable joint plate. The number of movable devices is reduced, solving problems such as wear of the shaft sleeve and pin shaft, stuck and warped joint plates, and joint plate falling due to broken limit blocks. This improves the working performance of the joint plate and extends the service life of the device.

[0026] As a further improvement to the above technical solution, a first recess is provided on the upper surface of the turnout beam 1 near one end of the track beam 2, which matches the joint plate of the turnout beam 1. A first threaded hole is provided on the upper surface of the first recess. A second recess is provided on the upper surface of the track beam 2 near one end of the turnout beam 1. The track support seat is provided on the second recess, and the track beam joint plate 21 is provided on the track support seat. By providing the first recess and the second recess for installing the turnout beam joint plate 11 and the track beam joint plate 21, and making the upper surface of the joint plate flush with the upper surface of the track beam 2 and the turnout beam 1 after installation, normal passage of trains is facilitated.

[0027] As a further improvement to the above technical solution, a plurality of first threaded holes are provided on the recess on the switch beam 1, and a first countersunk hole 14 matching the first threaded hole is provided on the switch beam joint plate 11. The switch beam joint plate 11 is fixed to the switch beam 1 by a first screw 13, and the switch support seat 3 is fixed to the switch beam 1 and the switch beam joint plate 11 respectively by a third screw. Preferably, a bolt and a threaded sleeve 6 are embedded in the switch beam 1 for installing the first thread. The countersunk hole is provided on the switch beam joint plate 11 to ensure that the upper end surface of the first screw 13 is on the upper surface of the first switch beam joint plate 11 to prevent it from affecting the passage of the train.

[0028] As a further improvement to the above technical solution, the support seat assembly further includes a joint plate seat 4, which is arranged between the track beam joint plate 21 and the track beam 2. By providing the joint plate seat 4 between the track beam 2 and the track beam joint plate 21, the track beam 2 can be further protected and the connection position can be strengthened.

[0029] As a further improvement to the above technical solution, the recesses on the track beam 2 are provided with a plurality of anchor bolts 5. The anchor bolts 5 are pre-embedded in the track beam 2. The upper ends of the anchor bolts 5 are provided with threaded sleeves 6, which are provided with threaded holes. The upper end surface of the threaded sleeves 6 is not higher than the bottom surface of the recesses on the track beam 2. The joint plate seat is provided with first through holes corresponding to the anchor bolts 5. The track beam joint plate 21 is provided with second countersunk holes 23 corresponding to the anchor bolts 5. The track beam joint plate 21 and the joint plate seat 4 are fixed to the track beam 2 via second screws 22. The second screws 22 pass through the track beam joint plate 21 and the joint plate seat 4 in sequence and are then screwed onto the threaded sleeves 6. By pre-embedding the anchor bolts 5 in the track beam 2 and providing threaded sleeves 6 above the anchor bolts 5 for installing the second screws 22, the second screws 22 pass through the track beam joint plate 21 and the joint plate seat plate and are then screwed onto the threaded sleeves 6, making the installation more stable. A countersunk hole is provided on the track beam joint plate 21 so that the upper end surface of the second screw rod 22 is lower than the upper surface of the track beam joint plate 21 to prevent it from affecting the operation of the train.

[0030] As a further improvement to the above technical solution, a plurality of reinforcing ribs 31 are provided between the two side plates of the switch support seat 3. The provision of the reinforcing ribs 31 increases the strength of the L-shaped switch support seat 3 so that it can stably support the switch beam joint plate 11.

[0031] As a further improvement to the above technical solution, the gap 12 between the track beam joint plate 21 and the switch beam joint plate 11 is 30 to 60 mm. The size of the gap 12 is controlled to prevent the gap 12 from being too small and causing collision between the joint plates when the switch beam 1 moves, and to prevent the gap 12 from being too large and affecting the safe passage of trains.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
