[0040] Embodiment 1

[0041] The embodiment of the present application provides a safety protection device based on a rail-mounted loading machine.

[0042] See Figure 1 , Figure 1 FIG. shows a schematic structural diagram of the safety protection device based on the rail-mounted loading machine provided by the embodiment of the present application. The safety protection device based on the rail-mounted loading machine includes: a radar sensing module 100, a main control module 200, and a combined limit module 300; the radar sensing module 100 is communicatively connected to the main control module 200 and is used to obtain a train detection signal; the main control module 200 is also communicatively connected to the combined limit module 300 and is used to determine whether a train enters according to the train detection signal. If so, the telescopic movement of the single boom is prohibited; the combined limit module 300 is used to determine the railway track occupied by the single boom according to the telescopic distance of the single boom and send a disabling signal to the main control module 200.

[0043] It should be noted that the rail-mounted loading machine is a device for loading coal onto trains and meets the layout of the railway area and the operation function of loading coal onto trains.

[0044] In this embodiment, asFigure 2 As shown, if there are three railway tracks, when the rail-mounted loading machine is in a standby state on one track, the radar detects that two or three trains have entered. The radar sends a train detection signal to the main control module 200. The main control module 200 determines that a train has entered and prohibits the telescopic single boom. At this time, the single boom of the loading machine cannot perform telescopic actions. When the radar detects that there are no trains entering on Track 2 and Track 3, the radar sends a train detection signal to the main control module 200. The main control module 200 determines that no train has entered and allows the single boom to telescope. At this time, the single boom can telescope freely. This solution can effectively prevent collisions between the boom of the loading machine and the train.

[0045] In one embodiment, the main control module 200 further includes a main control unit; the main control unit is communicatively connected to the combined limit module 300 and is configured to determine whether a train has entered according to the train detection signal. If not, it issues an allow signal and allows the single boom to telescope.

[0046] It should be understood that when the rail-mounted loading machine is operating, the single boom is kept in the extended state. The extended length of the single boom is different when operating on different tracks, resulting in the discharge port being above different tracks. Assuming that the single boom is not retracted in time after the operation is completed, it occupies the space above the train track, increasing the risk of collision with trains in the running or stationary state. Moreover, there is no protection device between the train and the rail-mounted loading machine, and serious collision accidents are likely to occur, causing serious consequences.

[0047] Therefore, in this application, the radar sensing module 100 is used to determine whether a train has entered, and the main control unit further controls the combined limit module 300 according to the judgment of the radar sensing module 100, so that the telescoping of the single boom is prohibited when a train enters, effectively reducing the possibility of collision accidents.

[0048] Optionally, as Figure 3 shown, the device further includes an interlock module 500; the main control module 200 is communicatively connected to the interlock module 500 and is configured to send the disable signal to the interlock module 500; the interlock module 500 is configured to determine an occupied track signal according to the disable signal and lock the disabled track of the train according to the occupied track signal. Optionally, the interlock module 500 is further communicatively connected to the radar sensing module 100 and is configured to determine an idle signal according to the allow signal and unlock the disabled track of the train according to the idle signal.

[0049] Specifically, when the single boom of the rail-mounted loading machine extends and occupies the railway track, the combined limit module 300 installed on the boom determines which track the single boom occupies according to the extended distance of the single boom.

[0050] In this embodiment, the main control module 200 is a loading machine PLC (Programmable Logic Controller) system, and the interlocking module 500 is a TYJL-III type (fully electronic) computer interlocking system for railway stations.

[0051] As Figure 4 shown, for example: when the track-type loading machine PLC receives the IB00001 signal input by the limit module, it determines that the single boom occupies track 1. At the same time, the radar scanning sensor installed on the side of the railway track senses that a train enters track 1, and the loading machine PLC receives the train entry signal IB00002 for track 1. At this time, the loading machine PLC emits the OB00001 red light warning signal, and at the same time sends the OB00002 occupied track signal to the interlocking module 500 through fiber optic communication. The interlocking module 500 marks track 1 as an occupied track signal in the station signal plan. At this time, the incoming train cannot enter track 1. When the boom does not occupy the railway, a yellow signal light is lit to remind, effectively avoiding collision accidents between the incoming train and the boom of the track-type loading machine. And Figure 4 NV1 in it indicates that the system power supply is normal, CAB indicates that the main control power supply in the operation room is switched on, and TIMER indicates a time-delay relay. In the figure, such as MB002064 and TB00001 are only serial numbers for indication and can be adjusted according to requirements.

[0052] In one embodiment, the device further includes: an indication module 400; the indication module 400 is communicatively connected to the main control module 200 and is configured to send an indication signal according to the occupied track signal.

[0053] Optionally, the indication module 400 includes a first indication signal light; the first indication signal light is communicatively connected to the main control module 200 and is configured to emit a red light warning according to the occupied track signal. Optionally, the indication module 400 includes a second indication signal light; the second indication signal light is communicatively connected to the main control module 200 and is configured to emit a yellow light warning according to the idle signal.

[0054] It should be understood that railway warning lights are a type of safety equipment mainly used to identify railway lines, stations and other sites, facilitating the identification of train operation personnel and passengers to ensure the safe and smooth railway transportation.

[0055] At present, the safe operation of trains mainly relies on railway warning lights and the driving of train drivers to ensure safe driving. When the loading machine is operating, the single boom is in the extended state. Assuming that the single boom is not retracted in time after the operation is completed, it occupies the space above the train track, increasing the risk of collision with trains in the running or stationary state. Moreover, there is no protection device between the train and the track-type loading machine, and serious collision accidents are likely to occur, resulting in serious consequences.

[0056] By obtaining the occupation signal of the train, this application prohibits the telescopic movement of the single boom and emits an indicator signal lamp to warn the train driver, thereby reducing the collision risk and increasing the safety of train operation.

[0057] In one embodiment, the radar sensing module 100 includes a plurality of radar sensing units; each of the radar sensing units is respectively arranged at the front end of the single boom.

[0058] It should be understood that the radar scanning sensor measures the spatial intrusion of an object and senses the object by emitting electromagnetic waves. Each group of radar sensors consists of a transmitter, a receiver, and a computer-controlled circuit. The transmitter emits a series of electromagnetic waves, which pass through the air, hit the object in front, and then bounce back. The receiver receives the reflected electromagnetic waves and converts them into signals. The computer-controlled circuit calculates the time of the reflected electromagnetic waves and then calculates the distance and speed of the object from the radar sensor according to the speed of the electromagnetic waves, so as to effectively achieve the control function of the rail-mounted loading machine.

[0059] In one embodiment, the combined limit module 300 is arranged below the tail of the single boom.

[0060] It should be understood that position limit detection devices are installed at multiple positions on the single boom of the rail-mounted loading machine. One or more groups of such position limit detection devices are installed to detect the position of the boom in the working state or non-working state.

[0061] A safety protection device based on a rail-mounted loading machine provided by the present utility model includes: a radar sensing module, a main control module, and a combined limit module. The radar sensing module is communicatively connected to the main control module and is used to obtain a train detection signal; the main control module is also communicatively connected to the combined limit module and is used to judge whether a train enters according to the train detection signal. If so, the telescopic movement of the single boom is prohibited; the combined limit module is used to determine the railway track occupied by the single boom according to the telescopic distance of the single boom and send a disabling signal to the main control module. By detecting whether a train enters the track and controlling the telescopic movement of the single boom according to the train detection signal, the probability of collision between the single boom and the train is reduced, the safety is improved, and the maintenance cost is reduced.
