Description

Technical Field

[0001] The present invention relates to a parking system, and particularly to an intelligent parking system for the tail of a marshalling yard. It belongs to the field of detector detection of parking brakes. Background Art

[0002] Currently, the existing parking system for parking brakes at the tail of a marshalling yard is arranged in a "2 + 1" mode. Under this arrangement mode, the parking capacity at the tail of the marshalling yard cannot be adjusted according to line conditions, vehicle types, the number of vehicles, and the position of the parked vehicles. During the process of parking and anti-rolling, if the line conditions are good and the reverse slope at the tail is large, the capacity will be wasted; if the line conditions are poor and the tail is a forward slope, the parking capacity will be insufficient. In the current structure, the distance between the second parking brake and the third parking brake is relatively far, and it is difficult for operating personnel to know the number of vehicles in this line. They can only judge by visual observation and experience. For the safety of some stations, in order to prevent vehicles from rolling out of the third parking brake and rolling into the turnout area, it is necessary to judge the number of vehicles in the track to decide whether to continue to release vehicles into this track. Therefore, visual observation and experience judgment are not only inefficient but also inaccurate, and are more likely to cause accidents. Summary of the Invention

[0008] The first track circuit, the second track circuit, and the third track circuit are installed on the railway track in sequence from front to back. The first track circuit, the second track circuit, and the third track circuit are located between the second speed measurement sensor and the fourth speed measurement sensor. The first track circuit, the second track circuit, the third track circuit, and the intelligent iron shoe shoe-on device are respectively connected to the circuit distribution box.

[0010] Further, the first track circuit and the second track circuit are located on the railway track between the second parking brake and the third parking brake, and the third track circuit is located between the second track circuit and the fourth speed measurement sensor.

[0011] Further, the length of the first track circuit is / of the distance between the second parking brake and the third parking brake, the length of the second track circuit is / of the distance between the second parking brake and the third parking brake, and the length of the third track circuit is the same as that of the second track circuit.

[0012] Further, the first parking brake, the second parking brake, the third parking brake, and the fourth parking brake are connected to the indoor parking controller through the CAN bus. Further, it further includes a position marking block, the position marking block is arranged on the piston rod of the oil cylinder, and the contact end of the displacement sensor is arranged towards the position marking block.

[0013] The most prominent feature and remarkable beneficial effect of the present invention are:

[0014] 1. Through the weight measurement sensor, speed measurement sensor, and track circuit equipment in this application, the parking system can intelligently control the braking state of the parking brake according to the vehicle type, number of vehicles, and the position of the parked vehicle, enabling it to better play the role of preventing vehicle slipping.

[0015] 2. The parking brake, weight measurement sensor, speed measurement sensor, track circuit, and automatic shoe-on device set in this application can effectively improve the capacity of the end-of-train parking system and increase the safety of shunting operations.

[0017] 4. By installing three sections of track circuits on the second stop device 12 and the third stop device 13 of this application, the current position of the vehicle can be indicated. When the third track circuit 53 is occupied by a vehicle, the information will be transmitted to the control machine, and the indoor parking controller 7 will emit an audible and visual signal to prompt the staff to confirm the vehicle's stopping position and take corresponding anti-rolling measures in a timely manner. If the staff does not respond to the alarm signal within 30 seconds, the automatic shoe placer at the tail end will install an iron shoe on the rail for anti-rolling. If the staff responds to the alarm signal, they can, according to the actual situation, choose to manually control whether the automatic shoe placer installs an iron shoe on the rail. If no iron shoe is installed, the third speed sensor 23 and the fourth speed sensor 24 will continuously monitor the vehicle's state. When the vehicle moves and is detected by the speed sensor, the control machine will continue to send an alarm to the staff and perform the above cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Working principle

[0029] When there is no vehicle staying between the fourth stopper 14 and the trailing fouling mark or signal during parking operation, the fourth stopper 14 is in the released state.

[0030] Before the vehicle starts to enter the fourth stopper 14 during parking operation, the weighing sensor 3 weighs each vehicle and records its weight level and sends it to the indoor parking controller 7, and the axle counter sensor 8 records the real-time number of axles passing by and sends it to the indoor parking controller 7. When the vehicle is braked by the first stopper 11 or the second stopper 12 and stays on the first stopper 11 or the second stopper 12, the fourth stopper 14 remains in the released state; when the vehicle is braked by the first stopper 11 or the second stopper 12 and its speed is higher than 5 km / h after being measured by the first speed sensor 21 and the second speed sensor 22, the indoor parking controller 7 controls the fourth stopper 14 to be in the braking state.

[0031] After that, as long as there is a vehicle occupying the first track circuit 51, the second track circuit 52, and the third track circuit 53, the fourth stopper 14 will always be in the braking state. When the vehicle passes the first track circuit 51 and presses on the second track circuit 52, the indoor parking controller 7 gives a prompt, indicating that the vehicle stored on this track has exceeded half of the trailing safety distance. When there is a vehicle occupying the third track circuit, the information will be transmitted to the indoor parking controller 7, and the indoor parking controller 7 will give an audible and visual signal to prompt the staff to confirm the vehicle staying position and take corresponding reinforcement anti-rolling measures in a timely manner. If the staff does not respond to the alarm signal within 30 seconds, the automatic shoe device 4 of the intelligent rail brake will install a rail brake on the rail for anti-rolling. If the staff responds to the alarm signal, according to the actual situation, the staff can choose to manually control whether the automatic shoe device installs a rail brake on the rail. If no rail brake is installed, the third speed sensor 23 and the fourth speed sensor 24 will monitor the vehicle state in real time. When the vehicle moves and is sensed by the speed sensor, the controller will continue to send an alarm to the staff and perform the above cycle.

[0032] The system is provided with a release button, which is operated by the staff on the indoor parking controller 7. Pressing the release button will release all stoppers, and all sensors will stop collecting data.
