Description

Technical Field

[0001] This utility model relates to the field of railway auxiliary structure technology, and in particular to a reinforcement device for preventing turnout locking arm from falling off. Background Technology

[0002] The turnout locking arm is a key piece of equipment used in railway line maintenance to lock the switch rail. At a turnout, when a train needs to travel in a straight line, the switch rail is separated from the stock rail, and the turnout locking arm maintains the stability of their distance, thus effectively locking the route. Existing turnout locking arms include a movable hook, a fixed top block, and a locking nut. In use, the fixed top block of the arm presses against the stock rail, the movable hook hooks the switch rail, and the locking nut is used to lock the connection, thus fixing the distance between the switch rail and the stock rail.

[0003] However, in actual use, the track vibration is severe when trains pass by, causing the turnout locking arm to move up and down between itself and the rail. With prolonged use, the turnout locking arm wears out significantly, and the fixing block easily detaches from the stock rail, seriously threatening the safety of train routes.

[0004] Therefore, a reinforcement device is proposed to prevent the turnout locking arm from falling off. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcement device to prevent the turnout locking arm from falling off, aiming to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a reinforcement device to prevent the turnout locking arm from falling off, comprising:

[0007] A connector for mounting on a base rail, the connector being located on the side of the base rail away from the fixed top block of the repulsor;

[0008] A pressure plate, which is used to press against the fixed top block of the repulsor on the side away from the base rail;

[0009] A spacing adjustment component is disposed between the connector and the pressure plate. The spacing adjustment component is used to adjust the spacing between the connector and the pressure plate, thereby adjusting the clamping force of the pressure plate.

[0010] Preferably, the connector includes two hooks for hooking onto the side of the base rail away from the fixed top block of the repeller, and the connector is connected to the spacing adjustment assembly.

[0011] Preferably, the spacing adjustment assembly includes two first screws, which are respectively fixed to the ends of the hooks. The pressure plate has two through holes, and the two first screws pass through the two through holes and are locked by a locking member.

[0012] Preferably, the locking member includes a first nut that is threadedly connected to the first screw, the first nut being located on the side of the pressure plate away from the hook, and a washer passing through the first screw, the washer being located between the first nut and the pressure plate.

[0013] This utility model discloses the following technical effects: After the turnout locking arm is installed on the switch rail and the main rail, the spacing adjustment component passes through the bottom of the main rail and the connecting piece is installed on the main rail. The pressure plate is pressed on the side of the fixed top block of the arm away from the main rail, so that the fixed top block of the arm is pressed tightly between the pressure plate and the main rail. The spacing adjustment component adjusts the distance between the connecting piece and the pressure plate, thereby adjusting the pressure force of the pressure plate, reinforcing the fixed top block on the turnout locking arm, and reducing the risk of the turnout locking arm falling off.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Turnouts are a crucial component of railway transportation systems, primarily used to change the direction of travel of trains or vehicles. They connect two or more tracks, allowing vehicles to switch between different tracks, thus ensuring the safety and efficiency of rail transport. Turnouts are not only used in railway systems but are also widely found in urban rail transit, subway, and light rail systems, providing vital support for the rapid and accurate turning of vehicles. Their sophisticated design and flexible operation make them an indispensable facility in modern transportation systems.

[0021] A switch is the core switching device of a railway turnout, responsible for switching, locking, and indicating the position of the switch rail. It consists of the switch rail, stock rail, connecting parts, and switching mechanism. By operating the switching mechanism, the position of the switch rail can be changed, thereby setting the direction of the turnout. The design of a switch must consider ease of operation, accuracy of switching, and reliability of locking to ensure that trains can smoothly and safely switch tracks when passing through the turnout. In highly automated railway systems, switches are also equipped with advanced control systems to achieve remote monitoring and automatic operation.

[0022] In practical applications, turnout locking arm devices are typically used to fix the distance between the switch rail and the stock rail after separation. During use, the fixed top block of the arm device is pressed against the stock rail, the movable hook is hooked onto the switch rail, and the locking nut is used to tighten the connection, thus fixing the distance between the switch rail and the stock rail. However, some challenges arise in actual use.

[0023] When a train passes, the track vibrates violently, causing the turnout locking arm to move up and down. With prolonged use, the turnout locking arm wears out severely, and the fixing block can easily detach from the stock rail, thus seriously threatening the safety of the train route.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Pressure plate 2 is used to press on the side of the fixed top block 10 of the repulsor arm away from the basic rail 1;

[0028] The spacing adjustment component is located between the connector and the pressure plate 2. The spacing adjustment component is used to adjust the spacing between the connector and the pressure plate 2, thereby adjusting the clamping force of the pressure plate 2.

A movable hook 11 is movably sleeved on the second screw 9, and a second nut 12 is threaded onto the second screw 9, located between the fixed top block 10 and the movable hook 11. In use, the second screw 9 is passed through the bottom of the switch rail 8, the fixed top block 10 is pressed against the side wall of the base rail 1, the movable hook 11 is hooked onto the bottom rail of the switch rail, and then the second nut 12 is tightened.

Two through holes 5 are provided on the pressure plate 2, and the two first screws 4 pass through the two through holes 5 and are locked by locking members.

[0032] In some alternative embodiments, the locking element includes a first nut 6 threadedly connected to the first screw 4, the first nut 6 being located on the side of the pressure plate 2 away from the hook 3, and a washer 7 passing through the first screw 4, the washer 7 being located between the first nut 6 and the pressure plate 2.

[0033] In use, after the turnout locking arm device is installed on the switch rail 8 and the main rail 1, the two first screws 4 are passed through the bottom of the main rail 1 and through the through hole 5 of the pressure plate 2.
