Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and specifically to an automatic anti-rolling device for locomotive depots and yards. Background Technique

[0002] Rolling away refers to the natural movement of locomotives and vehicles staying on the line (including lines with inspection pits) due to the lack of or improper wheel-stopping measures, which is a hidden "invisible killer" in railway transportation production and a major safety hazard endangering railway operation safety. In the past, there have been many railway accidents caused by the rolling away of locomotives and vehicles. Although anti-rolling systems and measures have been formulated, due to factors such as improper manual operation, weak monitoring, and ineffective implementation of measures, rolling away accidents of locomotives and vehicles occur frequently, with profound lessons.

[0003] Currently, most locomotive depots still use the anti-rolling measure of manually placing iron shoes (i.e., wheel stoppers), and the disadvantages of this anti-rolling measure are as follows: 1. The work of putting on and taking off iron shoes (wheel stoppers) is complicated and prone to omission, and they are easily stolen; 2. The safety and effectiveness of up-and-down track management are poor; 3. Safety inspections rely on manual labor, and it is impossible to control emergencies in a timely manner;

[0004] There is also a mechanical braking method using the principle of a switch machine - mast mechanism to achieve the anti-rolling effect. When using the switch machine - mast mechanism method, the disadvantages are as follows: 1. The maintenance process requires that there should be no other structures between the two tracks of the inspection pit, otherwise it will affect the inspection of the locomotive bottom. Moreover, this anti-rolling device exerts a lateral force on the inspection pit tracks and side walls, threatening the structural safety of the inspection pit, and the mechanical mechanism is large and occupies a large space; it is completely unsuitable for the anti-rolling of locomotives on lines with inspection pits such as locomotive maintenance yards and maintenance depots in locomotive depots; 2. There is no emergency release device, and the system loss is large during the movement with the shoes; 3. It cannot automatically report the status for unattended inspections;

[0005] Therefore, the anti-rolling effects achieved by existing anti-rolling means have low accuracy, sensitivity, and convenience, and cannot achieve an anti-rolling effect that integrates small occupied space, high automation level, high informatization level, emergency release design, and no manual intervention, and do not meet the automation anti-rolling use requirements of locomotive maintenance yards in locomotive depots. For this reason, an automatic anti-rolling device for locomotive depots and yards is proposed. Summary of the Invention

The fault indicator light adopts a three-color design, namely "green", "yellow", and "red", representing normal, waiting, and abnormal respectively, which is convenient for the staff to quickly identify the current state and take corresponding measures in time. Ultrasonic sensors, Hall sensors, and attitude sensors that cooperate with the electric control box 3 and a proximity switch 68 are respectively embedded on the intelligent rail brake 66 to accurately detect the current state of the intelligent rail brake 66 and improve the accuracy and sensitivity of the intelligent rail brake 66 when getting on and off the rail. A slide rail motor 67 that cooperates with the slide rail 2 is fixedly connected to the other side of the adjustment housing 1. A proximity switch 68 is arranged on the adjustment housing 1 near the intelligent rail brake 66. An emergency detachment mechanism 7 is arranged on the parallel flipping mechanism 6. The emergency detachment mechanism 7 includes a mounting fixed plate 71. The mounting fixed plate 71 is fixed on one side of the intelligent rail brake 66. The other side of the mounting fixed plate 71 is hinged to a movable plate 73 that cooperates with the intelligent rail brake 66 through a movable pin 72.An electrically controlled telescopic rod 74 is hinged on one side of the fixed plate 71 and the movable plate 73 facing each other, and a double torsion spring 75 elastically matched with the movable plate 73 is arranged on the movable pin shaft 72, and the anti-slip device body is arranged on both sides of the inspection pit in the maintenance field. By setting a parallel flip mechanism 6, the position, operating status and obstacle situation of the RFID electronic tag group 61, the warning light 62 and the barrier-free detector 63 are detected in real time, and the rotating motor 64 and the slide rail motor 67 provide a driving source, and then the connection frame 65 and the proximity switch 68 cooperate to realize the parallel and flip functions of the intelligent iron shoe 66, so as to meet the adjustment requirements of the upper and lower rail positions of the intelligent iron shoe 66. , so that the intelligent iron shoe 66 can be operated on and off the rails according to actual needs, and the accuracy and sensitivity of the intelligent iron shoe 66 in the process of going up and down the rails are improved. By setting the emergency disengagement mechanism 7, the electric control telescopic rod 74 provides the driving source, and then the installation fixed plate 71, the movable pin shaft 72, the movable plate 73 and the double torsion spring 75 cooperate to achieve the emergency disengagement effect of the intelligent iron shoe 66 when the electromechanical vehicle drives the intelligent iron shoe 66 to move abnormally, avoiding serious consequences, improving the anti-slip safety performance of the intelligent iron shoe 66, and realizing the anti-slip effect integrating small space occupation, high degree of automation, high degree of informatization, emergency disengagement design and no human intervention. ,

[0038] Working principle: When the intelligent iron shoe 66 performs anti-skid operation on the motor vehicle resting on the rail, the processor in the electric control box 3 first determines whether the defense command sent by the server is received. When the anti-skid command sent by the server is received, the parallel motion function module controls the slide rail motor 67 to start, and the anti-skid detection function module is used to defend the intelligent iron shoe 66. The slide rail motor 67 drives the slide table 4 on the motor mounting plate 5 to slide on the slide rail 2. The motor mounting plate 5 drives the intelligent iron shoe 66 to move to the anti-skid position of the target motor vehicle. When the slide table 4 slides on the slide rail 2, the RFID electronic tag group 61 distributed in a straight line array senses and detects the displacement distance and position of the intelligent iron shoe 66 on the motor mounting plate 5 until the intelligent iron shoe 66 moves accurately to the anti-skid surface of the target motor vehicle. At this time, the intelligent iron shoe 66 is controlled to start the anti-skid operation. The processor controls the barrier-free detector 63 through the obstacle detection function module to detect whether there are obstacles in the anti-skid area of ​​the rail and the intelligent iron shoe 66. When there is no defense timeout and obstacles in the anti-skid area of ​​the rail and the intelligent iron shoe 66, the processor then controls the rotating motor 64 and the proximity switch 68 to be turned on synchronously through the flip motion function module. The output shaft and coupling of the rotating motor 64 drive the intelligent iron shoe 66 to the predetermined anti-skid position on the rail through the connecting frame 65. At the same time, the ultrasonic sensor, Hall sensor and attitude sensor on the intelligent iron shoe 66 are used to verify its state to ensure that the intelligent iron shoe 66 and the anti-skid position of the rail are in the predetermined on-rail state. At this time, the processor controls the warning light 62 to be in a normal state through the sound and light alarm function module, so that the information automation anti-skid effect of the intelligent iron shoe 66 on the motor vehicle on the rail can be achieved;

[0039] When the processor receives the disarming instruction sent by the server through the anti-rolling detection function module, similarly, the processor successively controls the opening of the slide rail motor 67 and the rotating motor 64 through the parallel movement function module and the flipping movement function module, and then the slide rail motor 67 and the rotating motor 64 can reset the intelligent rail brake 66 to the initial position state;

[0040] When the ultrasonic sensor, Hall sensor and attitude sensor on the intelligent rail brake 66 sense abnormal movement of the motor vehicle with the rail brake, the processor immediately controls the opening of the electric control telescopic rod 74 through the emergency detachment function module. The installation fixing plate 71 and the movable pin shaft 72 provide articulated support compensation for the movable plate 73. Under the elastic compensation of the double torsion spring 75, the electric control telescopic rod 74 drives the intelligent rail brake 66 in the abnormal movement state to immediately disengage from the anti-rolling position of the rail through the movable plate 73. Then, the intelligent rail brake 66 in the emergency detachment state is physically detached from the connecting frame 65. At the same time, the processor controls the warning light 62 to present an abnormal alarm state through the sound and light alarm function module, so that the surrounding staff can quickly take corresponding measures, and the emergency detachment effect of the intelligent rail brake 66 can be achieved.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
