A protective structure for close-fitting inspection devices of railway ballastless turnout and ballasted turnout

Abstract

A protective structure for a close fit checker for a ballastless railway turnout and a ballasted railway turnout comprises a close fit checker and switch sleepers on both sides of the close fit checker. Since the structures on the switch sleepers of the ballastless railway turnout and the ballasted railway turnout are different, the present invention provides a protective structure for a close fit checker for the ballastless railway turnout and the ballasted railway turnout. Since the close fit checker is arranged between the switch sleepers, anti-smash devices are arranged on the switch sleepers on both sides of the close fit checker. Ice blocks on a motor vehicle body are blocked by the anti-smash devices after falling off, and the side panels on both sides of the close fit checker play an anti-smash role.

[0005] Preferably, the bottom plate and the side plates are L-shaped.

[0006] Preferably, the side plate is provided with a curved shape along the rail direction corresponding to the bottom of the rail.

[0007] A protective structure for a close fit checker of a railway ballasted turnout comprises a close fit checker and turnout sleepers on both sides of the close fit checker, a slide plate shoulder is provided on the turnout sleeper, an anti-smash device is provided on the slide plate shoulder, the anti-smash device consists of a bottom plate and a side plate, and the anti-smash device and the slide plate shoulder are fixed to the turnout sleeper by bolts.

[0008] Preferably, the bottom plate and the side plates are L-shaped.

[0009] Preferably, the side plate is provided with a curved shape along the rail direction corresponding to the bottom of the rail.

[0010] The beneficial effects of the present invention are as follows: since the structures on the switch sleepers of ballastless and ballasted railway turnouts are different, the present invention provides a protective structure for close contact checkers of ballastless and ballasted turnouts. Since the close contact checker is arranged between the switch sleepers, anti-smash devices are arranged on the switch sleepers on both sides of the close contact checker. After ice blocks on the EMU car body fall off, they are blocked by the anti-smash devices, and the side panels on both sides of the close contact checker play an anti-smash role.

[0016] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0017] The technical solution of the present invention is as follows: A protective structure for a close-fitting inspection device of a ballastless railway turnout, according to Figure 1 As shown, it includes a close-fitting inspection device 1 and turnout sleepers 2 on both sides of the close-fitting inspection device 1. Figure 2 As shown, a V-shaped groove 3 is provided on the switch sleeper 2. In order to prevent the close-fitting checker from being damaged, anti-smashing devices 4 are provided along the V-shaped groove 3 on the switch sleepers 2 on both sides of the close-fitting checker 1. The anti-smashing device 4 is composed of a bottom plate 5 and a side plate 6. The side plates on both sides of the close-fitting checker play an anti-smashing role. A right-angle shoulder 7 is provided on the anti-smashing device 4, a V-shaped protrusion 8 is provided at the bottom of the right-angle shoulder 7, a bolt hole for a bolt 9 to pass through is provided on the right-angle shoulder 7, a through groove 10 for the bolt 9 to pass through is opened on the bottom plate 5, and the right-angle shoulder and the anti-smashing device are fixed to the switch sleeper by bolts. Since the V-shaped protrusion at the bottom of the right-angle shoulder is matched with the V-shaped groove, but the anti-smashing device causes a gap between the right-angle shoulder and the V-shaped groove, V-shaped pads 11 are provided on both sides of the bolt 9 in the through groove 10. Figure 3As shown, a concave surface 12 is provided on the upper part of the V-shaped pad 11, which is engaged with the V-shaped protrusion 8 at the bottom of the right-angle shoulder 7, and the concave surface is a V-shaped concave surface. The V-shaped pad is an extension of the V-shaped protrusion of the right-angle shoulder. A convex surface 13 is provided on the bottom surface of the V-shaped pad 11, which is engaged with the V-shaped groove 3, and the convex surface is a V-shaped convex surface. Side surfaces 14 that cooperate with the through groove 10 are provided on both sides of the V-shaped pad 11.

[0018] The bottom plate 5 and the side plate 6 are processed into an L-shape by steel plates.

[0019] The side plate 6 is provided with a curved shape along the rail direction corresponding to the bottom of the rail.

[0020] A close-fitting inspection device protection structure for a railway ballasted turnout, such as Figure 4 As shown, it includes a close-fitting inspection device 1 and turnout sleepers 2 on both sides of the close-fitting inspection device 1. Figure 5 As shown, a slide plate shoulder 15 is provided on the switch sleeper 2, and an anti-smashing device 4 is provided on the slide plate shoulder 15. The anti-smashing device 4 is composed of a bottom plate 5 and a side plate 6. The side plates on both sides of the inspector are closely attached to play a protective role. The anti-smashing device 4 and the slide plate shoulder 15 are fixed to the switch sleeper 2 by bolts 9.

[0021] The bottom plate 5 and the side plate 6 are processed into an L-shape by steel plates.

[0022] The side plate 6 is provided with a curved shape along the rail direction corresponding to the bottom of the rail.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
