TECHNICAL FIELD

[0001] The utility model relates to rail transit overhauling equipment field, concretely relates to subway turnout sliding bed plate. BACKGROUND

[0002] The subway turnout sliding bed plate plays a vital role in subway operation, first, the sliding bed plate provides stable support for the moving part of the turnout, ensuring that it does not sink or deviate when the train passes; second, it guides the movement of the switch rail and the stock rail, and the turnout can accurately switch the track direction to ensure that the train can pass through the turnout smoothly and safely.

[0003] The existing subway turnout sliding bed plate is various, for example, the sliding bed plate used in Shenyang subway line 10 is shown in the figure Figure 1 Each group of turnout is equipped with 32 sliding bed plates, and because the center distance of the anchor bolt hole of the sliding bed plate from the edge of the sliding bed plate is different, there are 10 specifications from 76mm to 88mm, which makes the daily fault replacement complex and increases the difficulty of spare parts management. The main reason for the diversification of the existing sliding bed plate is that the anchor bolt hole positioning size is fixed, and different specifications of sliding bed plates need to be provided, and a universal replacement of a specification of sliding bed plate cannot be achieved. This not only increases the management cost, but also has an adverse effect on the maintenance efficiency. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the problem that the sliding bed plate cannot be universal, and provides an adjustable distance sliding bed plate, which solves the problem that the existing sliding bed plate anchor bolt hole positioning size difference leads to non-universal problem through the design of bidirectional distance adjusting structure.

[0005] The utility model provides a kind of adjustable distance sliding bed plate, and fixed plate is provided on pad, and two ends have anchor bolt hole, the anchor bolt hole is long hole, long hole outer edge is lower buckle plate, lower buckle plate long side tooth, upper buckle plate has the tooth that is matched with lower buckle plate, upper buckle plate has anchor bolt fixed hole, fixed hole is positionally corresponding with anchor bolt hole, and lower buckle plate and upper buckle plate are engaged by tooth.

[0006] Further, the lower buckle plate and the pad are integrated structure, and the long side of the anchor bolt long hole on the pad is provided with a row of teeth.

[0007] Further, the lower buckle plate and the pad are split structure, and the pad is welded with the lower buckle plate, the lower buckle plate is provided with long hole corresponding to the anchor bolt hole, and the long side of the long hole is provided with a row of teeth.

[0008] Further, the anchor bolt fixed hole is round hole.

[0009] Further, the tooth cross section is isosceles trapezoidal.

[0010] Further, the tooth is isosceles trapezoidal inclined tooth with 45° base angle.

[0011] The utility model discloses a bed plate compared with prior art has remarkable progress, it is reflected in the following several aspects:

[0012] The anchor bolt hole of the bed plate is designed as a long hole distance adjusting structure, so that the adjustable range covers-10mm to +10mm, and one person can complete the adjustment in the range of ±10mm, and the bed plate has higher universality and stability.

[0013] 2. The two-way distance adjusting buckle is used, the lower buckle is integrally or separately welded around the anchor bolt hole of the bed plate, and is locked by engaging and bolt fixing through the upper buckle; the 45° helical tooth engaging design is two-way self-locking engagement, horizontal automatic locking is realized, and the anti-lateral impact capacity is improved by 60% than the traditional structure.

[0014] The tooth is treated by laser quenching, and is ground in process, and the tooth spacing error is less than or equal to 0.1mm, so that millimeter-level positioning can be realized, and the repeated positioning accuracy is ensured.

[0015] 3. The operation and maintenance efficiency is improved, and the economic benefit is outstanding, one person can complete the adjustment in the range of ±10mm within 3 minutes, the maintenance efficiency is improved by 40%, the bed plate model is unified, can be adapted to different opening direction turnouts, can be adapted to existing turnout reconstruction (adaptation rate 98%), and the installation time of the new project is saved by 35%; the types of inventory are greatly reduced, the spare part management efficiency is improved, the daily maintenance work is simplified, and the operation and maintenance cost is reduced.
