Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation, and in particular to a signal lamp for railway turnout and a control method thereof. Background Art

[0002] Railway signal lights are mainly used to transmit various states along the railway, so that drivers and shunters can quickly understand the railway conditions ahead and take measures to control the running status and speed of the train. In actual use, some railway turnouts are not included in the turnout interlocking system. For outdoor single-action turnouts that are not included in the interlocking, after the electric operation is realized, the turnout conversion is completed. The driver cannot directly confirm whether the turnout equipment is converted in place, and cannot directly judge whether the railway meets the traffic conditions. Therefore, the present invention proposes a turnout signal light and a control method thereof to ensure that a corresponding locking indication is given after the turnout conversion is completed to guide the train operation.

[0003] In the prior art, visual detection technology can be used to collect on-site information, process and identify it through electronic equipment, and then transmit the judgment result to a signal light or a player, so as to achieve the purpose of conveying information to the driver through the signal light or the player.

[0004] However, in actual use, this method has high equipment costs and requires professional personnel to repair the equipment when it fails, which further increases maintenance costs. Secondly, this method does not display information intuitively, making it inconvenient for the driver to keep an eye on the situation. Sometimes, the shunter needs to send instructions to the driver, which makes it inconvenient for the driver to obtain information in a timely manner, resulting in low train operation efficiency and inaccurate information. In addition, after long-term use or in snowy conditions, the surface of the signal light will be covered, affecting actual observation. Summary of the invention

The connecting rod 15 is provided with a signal light body 1, and the signal light body 1 is clamped with the connecting rod 15 through a clamping mechanism 14, and the signal light body 1 is provided with a control mechanism.

[0046] When in use, the base 11 and the main pole 3 realize the installation of the overall structure, the warning sign 2 is used for preliminary prompting, so that the driver knows that there is a turnout at this railway, the connecting rod 15 is used to realize the installation of the signal light body 1, and the control mechanism is used to control the on and off of the signal light body 1, and convey to the driver whether the turnout conversion here is completed through the on and off status of the signal light body 1. When the turnout conversion is completed, the signal light body 1 is illuminated by the control mechanism, and the driver can be prompted by the signal light whether the turnout is indeed passed. This solution is convenient and simple, easy to observe, and there is no need for the shunter to send instructions to the driver, which is convenient for the driver to obtain information in time, thereby improving the train operation efficiency by reducing the information transmission time.

[0047] In this embodiment, the base 11 is fixedly connected by pouring cement through holes in the ground. This method is easy to implement and has low difficulty.

[0048] In this embodiment, the surface of the warning sign 2 is affixed with reflective stickers, which has high night visibility and enhances safety, preventing unrelated personnel from being unable to observe the existence of the main pole 3 when the signal light body 1 is not started under Hunan conditions.

[0049] In this embodiment, the main pole 3 is provided with a display screen 9 and a speaker 4, and the warning sign 2, the signal light body 1, the display screen 9 and the speaker 4 face the same side.

[0050] When in use, the display screen 9 is equipped with a signal receiver for receiving railway information and displaying it in the form of text on the display screen 9. In an emergency, the signal receiver can receive voice signals and play voice signals through the speaker 4. This method can receive and display the road conditions ahead, and notify the driver and surrounding personnel in the form of text or voice, and can broadcast the road conditions ahead to prevent danger.

[0051] In this embodiment, an inspection staircase 10 is provided on the other side of the main pole 3; the inspection staircase 10 is fixedly connected to the main pole 3; when in use, this method can assist maintenance personnel in carrying out maintenance.

[0052] Embodiment 2:

[0053] Based on the first embodiment, Figure 3 As shown; the clamping mechanism 14 includes;

[0054] A mounting sleeve 1404, which is disposed on the signal lamp body 1, and is provided with an adjusting bolt 1404, and an outer wall of the mounting sleeve 1404 is provided with a protective shell 1402;

[0055] An adjusting bolt 1404, the outer wall of the adjusting bolt 1404 is movably connected to the mounting sleeve 1404, and a clamping block 1401 is provided at one end of the adjusting bolt 1404 close to the center of the mounting sleeve 1404;

[0056] The clamping block 1401 is arranged on the adjusting bolt 1404, and the clamping block 1401 is arranged in an arc shape.

[0057] In this embodiment, the end of the mounting sleeve 1404 close to the signal lamp body 1 is fixedly connected to the signal lamp by welding, and a plurality of bolt holes are evenly arranged on the circumference of the side wall of the mounting sleeve 1404, and the adjusting bolt 1404 is threadedly connected to the mounting sleeve 1404 through the bolt holes; the end of the adjusting bolt 1404 close to the center of the mounting sleeve 1404 is fixedly connected with a clamping block 1401; the clamping block 1401 is arranged in an arc shape.

[0058] When in use, rotate the adjusting bolt 1404 so that the end of the adjusting bolt 1404 close to the center of the mounting sleeve 1404 is away from the center of the mounting sleeve 1404, and the connecting rod 15 is inserted into the mounting sleeve 1404. At this time, the clamping block 1401 fixedly connected to the mounting sleeve 1404 will not collide with the connecting rod 15. After the insertion is completed, the center of the connecting rod 15 is placed at the center of the mounting sleeve 1404, and one of the adjusting bolts 1404 is arbitrarily rotated. In actual use, the limited rotation of the lower adjusting bolt 1404 can save the construction workers' effort and reduce the possibility of hand soreness and instability. When the clamping block 1401 fixedly connected to the adjusting bolt 1404 contacts the connecting rod 15, turn the next adjusting bolt Bolt 1404 until the clamping blocks 1401 on all adjusting bolts 1404 are in contact with the connecting rod 15. At this time, turn the adjusting bolt 1404 again to increase the pressure at the contact point between the clamping block 1401 and the connecting rod 15 to prevent it from falling off. When the signal lamp body 1 is damaged and needs to be repaired, turn the adjusting bolt 1404 so that the clamping block 1401 is no longer in contact with the adjusting bolt 1404, pull the signal lamp body 1 to pull the connecting rod 15 out of the mounting sleeve 1404, and the disassembly is completed at this time. Replace the undamaged signal lamp body 1 and install it in the original position of the connecting rod 15 to complete the repair. This method realizes convenient installation and disassembly, does not require professional technicians to perform professional operations, and reduces the maintenance cost during equipment maintenance.

[0059] In this embodiment, the protective shell 1402 is sleeved on the outer wall of the mounting sleeve 1404, and the protective shell 1402 is made of corrosion-resistant material; this method can increase the service life of the mounting sleeve 1404, while avoiding the need for the entire mounting sleeve 1404 to be made of corrosion-resistant material, thereby reducing equipment costs.

[0060] In this embodiment, the surface of the clamp block 1401 is roughened, which can increase the friction between the clamp block 1401 and the connecting rod 15, making the clamp block 1401 and the connecting rod 15 in closer contact and preventing the connection between the clamp block 1401 and the connecting rod 15 from sliding.
