Description

A support device for the protection of the switch rails of buried turnouts Technical Field

[0001] This utility model relates to the field of track maintenance equipment technology, and in particular to a support device for the protection of the switch rails of buried turnouts. Background Technology

[0002] Traditional turnout hook locks are locking devices used for railway turnout switch rails. In the event of a turnout malfunction or construction work, or when the turnout is locked due to power loss, the hook lock extends from under the rail to lock the switch rail to the stock rail to ensure traffic safety and the correct opening position of the turnout. During use, a wooden plug is driven into the outer side of the switch rail on the side that is in contact with the stock rail to secure it. However, due to the low hardness and strength of the wooden plug, and its poor load-bearing capacity, the surface of the plug is prone to mold and cracking over time. Once the wooden plug deforms, it can no longer reliably secure the switch rail, thus failing to effectively maintain the tight contact of the switch rail, posing a certain risk and failing to meet the requirements of long-term operation. Summary of the Invention

[0003] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a support device for the protection of the switch rail of an underground turnout. The opening degree of the switch rail support device can be flexibly adjusted, and the switch rail and auxiliary cabinet can be firmly supported, effectively improving safety.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A support device for protecting the switch rail of an underground turnout includes a first support plate, a second support plate, a telescopic drive mechanism, and an auxiliary fixing clamp. The first support plate and the second support plate are arranged parallel to each other and spaced apart. The telescopic drive mechanism is disposed between the first support plate and the second support plate and is used to drive the first support plate and the second support plate to move closer or further apart. The auxiliary fixing clamp is disposed at one end of the second support plate and a clamping portion is formed between the auxiliary fixing clamp and the second support plate. The side of the first support plate away from the second support plate is the switch rail support surface, and the side of the second support plate away from the first support plate is the auxiliary rail support surface.

[0006] In one embodiment, the telescopic drive mechanism includes a drive screw, a first transmission member, a second transmission member, a first rhomboid telescopic member, and a second rhomboid telescopic member. A first transmission nut and a second transmission nut are respectively rotatably disposed on the first and second transmission members, and the first and second transmission nuts are threaded onto the drive screw, with the thread directions of the first and second transmission nuts opposite. The first and second rhomboid telescopic members are located on opposite sides of the drive screw. Two opposite endpoints of the first rhomboid telescopic member are hinged to the first support plate and the second support plate, respectively, and the other two opposite endpoints of the first rhomboid telescopic member are hinged to the first and second transmission members, respectively. Two opposite endpoints of the second rhomboid telescopic member are hinged to the first support plate and the second support plate, respectively, and the other two opposite endpoints of the second rhomboid telescopic member are hinged to the first and second transmission members, respectively.

[0007] In one embodiment, the first rhomboid telescopic member includes four first connecting arms of equal length, arranged in a rhomboid pattern. Two of the first connecting arms have one end coaxially hinged to the first transmission member, and the other ends of these two first connecting arms are respectively hinged to the first support plate and the second support plate. The other two first connecting arms have one end coaxially hinged to the second transmission member, and the other ends of these two first connecting arms are respectively hinged to the first support plate and the second support plate. The second rhomboid telescopic member includes four second connecting arms of equal length, arranged in a rhomboid pattern. Two of the second connecting arms have one end coaxially hinged to the first transmission member, and the other ends of these two second connecting arms are respectively hinged to the first support plate and the second support plate. The other two second connecting arms have one end coaxially hinged to the second transmission member, and the other ends of these two second connecting arms are respectively hinged to the first support plate and the second support plate.

[0008] In one embodiment, a first groove is coaxially provided on one end face of the first transmission member, and the first transmission nut is rotatably disposed in the first groove. The first transmission member also includes a first locking nut, which is threaded onto the drive screw and abuts against the end face of the first transmission member with the first groove. The thread direction of the first locking nut is the same as that of the first transmission nut. Similarly, a second groove is coaxially provided on one end face of the second transmission member, and the second transmission nut is rotatably disposed in the second groove. The second transmission member also includes a second locking nut, which is threaded onto the drive screw and abuts against the end face of the second transmission member with the second groove. The thread direction of the second locking nut is the same as that of the second transmission nut.

[0009] In one embodiment, the side of the first support plate away from the switch rail support surface is provided with two first hinge seats, and one end of the first rhomboid telescopic member and the second rhomboid telescopic member are respectively hinged to the two first hinge seats; the side of the second support plate away from the auxiliary rail support surface is provided with two second hinge seats, and the other end of the first rhomboid telescopic member and the second rhomboid telescopic member are respectively hinged to the two second hinge seats.

[0010] In one embodiment, one end of the drive screw is coaxially connected to a screw terminal.

[0011] In one embodiment, the auxiliary fixing clamp is a U-shaped clamp with a clamping opening. One end of the second support plate extends into the auxiliary fixing clamp from the clamping opening, and the second support plate is fixedly connected to one inner side of the auxiliary fixing clamp. The clamping part is formed between the other inner side of the auxiliary fixing clamp and the second support plate.

[0012] As one embodiment, a strong magnet is also included, which is detachably inserted into the clamping part.

[0013] Compared with traditional technologies, the advantages of the switch rail support device described in this utility model are:

[0014] This utility model's switch rail support device can replace the traditional wooden plug for manual locking of the switch rail. The first and second support plates of this utility model abut against the switch rail and the auxiliary rail, respectively. By rotating the drive screw with a tool, the first and second transmission components can move relative to or away from each other, thereby adjusting the extension of the first and second rhomboid telescopic components, and thus adjusting the distance between the first and second support plates, thereby adapting to the distance between the switch rail and the auxiliary rail. Specifically, this invention uses an auxiliary fixing clamp to hold and fix the auxiliary rail, and a strong magnet further clamps the auxiliary rail to increase the anti-detachment performance between the switch rail support device and the auxiliary rail. Then, a tool is used to rotate the drive screw, causing the first transmission nut on the first transmission component and the second transmission nut on the second transmission component to move relative to each other. This, in turn, causes the first and second transmission components to move relative to each other in the axial direction of the drive screw. As a result, the first and second rhomboid telescopic components unfold relative to each other, causing the first support plate to move away from the second support plate until the first support plate abuts against the switch rail. This achieves the effect of temporarily locking the auxiliary rail and the switch rail by the switch rail support device of this invention. In other words, the switch rail support device of this invention can flexibly adjust the opening degree of the switch rail support device and can firmly support the switch rail and the auxiliary cabinet, effectively improving safety and greatly extending the service life of the switch rail support device.

[0023] Please refer to Figures 1 to 4; This embodiment provides a support device for the protection of the switch rail of an underground turnout, including a first support plate 10, a second support plate 20, a telescopic drive mechanism, and an auxiliary fixing clamp 80. The first support plate 10 and the second support plate 20 are arranged parallel to each other and spaced apart. The telescopic drive mechanism is disposed between the first support plate 10 and the second support plate 20, and is used to drive the first support plate 10 and the second support plate 20 to move closer or further apart. The auxiliary fixing clamp 80 is disposed at one end of the second support plate 20, and a clamping part is formed between the auxiliary fixing clamp 80 and the second support plate 20. The side of the first support plate 10 away from the second support plate 20 is the switch rail support surface, and the side of the second support plate 20 away from the first support plate 10 is the auxiliary rail support surface.

[0024] Specifically, the telescopic drive mechanism of this embodiment includes a drive screw 30, a first transmission member 40, a second transmission member 50, a first rhomboid telescopic member 60, and a second rhomboid telescopic member 70; a first transmission nut 41 and a second transmission nut 51 are respectively rotatably provided on the first transmission member 40 and the second transmission member 50, respectively, and the first transmission nut 41 and the second transmission nut 51 are respectively threaded onto the drive screw 30, and the thread directions of the first transmission nut 41 and the second transmission nut 51 are opposite; the first rhomboid telescopic member 60 and the second rhomboid telescopic member 70 are respectively located at Both sides of the drive screw 30; two opposite ends of the first rhomboid telescopic member 60 are respectively hinged to the first support plate 10 and the second support plate 20, and the other two opposite ends of the first rhomboid telescopic member 60 are respectively hinged to the first transmission member 40 and the second transmission member 50; two opposite ends of the second rhomboid telescopic member 70 are respectively hinged to the first support plate 10 and the second support plate 20, and the other two opposite ends of the second rhomboid telescopic member 70 are respectively hinged to the first transmission member 40 and the second transmission member 50. One end of the drive screw 30 is coaxially connected to a screw terminal.

[0025] The first rhomboid telescopic member 60 includes four first connecting arms 61 of equal length, arranged in a rhomboid pattern. Two of the first connecting arms 61 have one end coaxially hinged to the first transmission member 40, and the other ends of these two first connecting arms 61 are respectively hinged to the first support plate 10 and the second support plate 20. The other two first connecting arms 61 have one end coaxially hinged to the second transmission member 50, and the other ends of these other two first connecting arms 61 are respectively hinged to the first support plate 10 and the second support plate 20. Above; the second rhomboid telescopic member 70 includes four second connecting arms 71 of the same length, which are arranged in a rhomboid shape. Two of the second connecting arms 71 are coaxially hinged at one end to the first transmission member 40, and the other ends of the two second connecting arms 71 are respectively hinged to the first support plate 10 and the second support plate 20. The other two second connecting arms 71 are coaxially hinged at one end to the second transmission member 50, and the other ends of the other two second connecting arms 71 are respectively hinged to the first support plate 10 and the second support plate 20.

[0026] In addition, the side of the first support plate 10 away from the switch rail support surface is provided with two first hinge seats 11, and one end of the first rhomboid telescopic member 60 and the second rhomboid telescopic member 70 are respectively hinged to the two first hinge seats 11; the side of the second support plate 20 away from the auxiliary rail support surface is provided with two second hinge seats 21, and the other end of the first rhomboid telescopic member 60 and the second rhomboid telescopic member 70 are respectively hinged to the two second hinge seats 21.

[0027] It can be understood that the hinge method in this embodiment can use pins or pins to hinge two components that need to be hinged. The number of pins or pins required can be selected according to the actual situation, which will not be elaborated here.

[0028] In this embodiment, one end face of the first transmission member 40 is coaxially provided with a first groove, and the first transmission nut 41 is rotatably disposed in the first groove. The first transmission member 40 also includes a first locking nut 42, which is threaded onto the drive screw 30 and abuts against the end face of the first transmission member 40 with the first groove. The thread direction of the first locking nut 42 is the same as that of the first transmission nut 41. One end face of the second transmission member 50 is coaxially provided with a second groove, and the second transmission nut 51 is rotatably disposed in the second groove. The second transmission member 50 also includes a second locking nut 52, which is threaded onto the drive screw 30 and abuts against the end face of the second transmission member 50 with the second groove. The thread direction of the second locking nut 52 is the same as that of the second transmission nut 51. In this embodiment, the first transmission nut 41 and the first locking nut 42 can rotate synchronously in the same direction during the rotation of the drive screw 30, and move in the same direction under the action of the drive screw 30, so that the first transmission member 40 can move in that direction. Similarly, the second transmission member 50 adopts a similar principle, which will not be elaborated here. When the drive screw 30 rotates, the first transmission member 40 and the second transmission member 50 can move relative to each other or in opposite directions, and the specific direction of movement depends on the forward or reverse rotation of the drive screw 30.

[0029] In this embodiment, the auxiliary fixing clamp 80 is a U-shaped clamp with a clamping opening. One end of the second support plate 20 extends into the auxiliary fixing clamp 80 through the clamping opening, and the second support plate 20 is fixedly connected to one inner side of the auxiliary fixing clamp 80. The clamping portion is formed between the other inner side of the auxiliary fixing clamp 80 and the second support plate 20. Additionally, the switch rail support device in this embodiment also includes a strong magnet 81, which is detachably inserted into the clamping portion.

[0030] Compared with traditional technology, the switch rail support device of this utility model can replace the traditional wooden plug for manual locking of the switch rail. The first support plate 10 and the second support plate 20 of this utility model abut against the switch rail and the auxiliary rail respectively. By rotating the drive screw 30 with a tool, the first transmission member 40 and the second transmission member 50 can move relative to or away from each other, thereby adjusting the extension amount of the first diamond-shaped telescopic member 60 and the second diamond-shaped telescopic member 70, and thus adjusting the distance between the first support plate 10 and the second support plate 20, thereby adapting to the distance between the switch rail and the auxiliary rail. Specifically, this invention uses an auxiliary fixing clamp 80 to clamp and fix the auxiliary rail, and a strong magnet 81 to further clamp the auxiliary rail, thereby increasing the anti-detachment performance between the switch rail support device and the auxiliary rail. Then, a tool is used to rotate the drive screw 30, which causes the first transmission nut 41 on the first transmission member 40 and the second transmission nut 51 on the second transmission member 50 to move relative to each other, thereby driving the first transmission member 40 and the second transmission member 50 to move relative to each other in the axial direction of the drive screw 30. In this way, the first rhomboid telescopic member 60 and the second rhomboid telescopic member 70 unfold relative to each other, causing the first support plate 10 to move away from the second support plate 20 until the first support plate 10 abuts against the switch rail, thereby achieving the effect of temporary locking of the auxiliary rail and the switch rail by the switch rail support device of this invention. In other words, the switch rail support device of this invention can flexibly adjust the opening degree of the switch rail support device and can firmly support the switch rail and the auxiliary cabinet, effectively improving safety, and at the same time greatly extending the service life of the switch rail support device.

[0031] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model's switch rail support device. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
