Description

Technical Field

[0001] The utility model relates to the technical field of railway track turnout components, in particular to an oil-resistant insulating railway pad for a turnout. Background Art

[0002] Railway transportation is responsible for two important transportation tasks: freight and passenger transportation. In particular, with the construction of high-speed railways and the transportation of heavy-load turnouts, train speeds have been greatly improved, and the safety of railway transportation has shown extraordinary importance.

[0003] As one of the important parts of railway track, turnout undertakes the task of train switching; the slide plate is an important part of the turnout that supports the point rail and provides sliding space for it. It is mainly used to support the pressure from the point rail and the base rail, and transfer it to the turnout sleeper. At present, the slide plates used in domestic railway turnouts mainly include ordinary speed turnout slide plates, speed-up turnout slide plates, and passenger-dedicated turnout slide plates. Their structures all include a slide bed plate and a bottom plate, and the plate and the bottom plate are connected by welding.

[0004] During railway track transportation, the rails are supported on the sleepers. The track surface at the switch is complex. After years of operation, the ballast is not easy to maintain and tamp. The ballast under the sleepers at the switch often slips and leaks. The track here is equivalent to losing support. Especially in heavy-load railways, under huge impact, it is very easy to cause local damage, wear, and even breakage, posing a huge safety hazard.

[0005] In the prior art, there is a one-piece pad, which is equivalent to connecting two pads together as a whole to solve the problem of empty sleepers. However, this solution only relies on steel plates of similar thickness to the pads to support the empty sleepers, and the strength and stiffness are far from achieving the effect, and it is unable to effectively resist the large impact of the empty sleepers. Utility Model Content

[0006] The utility model aims to provide an oil-resistant insulating railway pad for a turnout, which can ensure that the pad has sufficient strength to support the track and prevent the track from being damaged by sudden deformation and impact.

[0007] The embodiments of the present invention are implemented by the following technical solutions:

[0008] An oil-resistant insulating railway pad for a turnout comprises a base plate and a pad arranged on the base plate; a plurality of balls are movably arranged on the upper surface of the pad, and the bottom surface of the pad is connected to the base plate via a connecting piece; the connecting piece can penetrate the pad and the base plate and form a spacing cavity between the pad and the base plate.

[0009] Furthermore, the balls are evenly distributed on the surface of the pad.

[0010] Furthermore, a plurality of grooves are arranged on the surface of the pad, and one of the balls is rotatably arranged in one of the grooves.

[0011] Furthermore, the connecting member is an arc-shaped or U-shaped supporting plate with an opening facing downward.

[0012] Furthermore, the upper portion of the connecting member is located inside the pad, and the bottom of the connecting member abuts against the bottom of the base plate.

[0013] Furthermore, a plurality of supporting columns are arranged in the spacer cavity.

[0014] Furthermore, a reinforcing support column is provided between the side surface of the pad and the bottom plate.

[0015] Furthermore, a slide bed plate and an iron seat are respectively provided at two ends of the upper surface of the pad.

[0016] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0017] The utility model has a reasonable design. When in use, the point rail of the turnout is supported by the ball bearings, so that rolling friction occurs between the point rail of the turnout and the pad, which greatly reduces the running resistance of the turnout. More importantly, the utility model uses a connecting piece to connect the pad with the bottom plate to maintain its stability, and forms a spacing cavity at the bottom of the connecting piece to resist the pressure in the running direction, and can provide space for ballast, and use the accumulated ballast to enhance the compressive strength of the pad, so that the pad has sufficient strength to support the track and prevent the track from being damaged by sudden deformation impact.
