Description

Technical Field

[0001] This utility model relates to the field of underground electric locomotive technology, specifically an underground remote-controlled electric locomotive. Background Technology

[0002] The mine safety situation is severe. Currently, under the major impetus of emergency management departments to promote "mechanization, automation, and intelligentization," the number of personnel going underground is being reduced to lower operational safety risks. Underground electric locomotives primarily handle the transportation of ore / rubble and other materials. Currently, loading and unloading of these locomotives requires slow, inching movements to ensure proper positioning of the mine cars and facilitate loading and unloading. When transporting materials, slow speeds and inching movements on curves are also necessary to reduce material swaying and ensure stable transport. However, the limited visibility of the locomotive driver in the cab makes precise control difficult, resulting in low efficiency and a higher risk of safety issues.

[0003] 1. When loading mine cars with electric locomotives, the locomotives are required to operate slowly and inching. For auxiliary intermediate transportation where the ore volume is not fully loaded, dedicated ore-discharging personnel are also required. The locomotives are loaded slowly with intermittent starting and stopping, and audible and visual signals are used, which increases labor costs and safety risks. Alternatively, a "whip" can be used to operate the locomotive and ore-discharging machine by a single person. When there are many mine cars, the length of the "whip" needs to be increased to ensure that the ore-discharging machine can effectively load the mine cars, which increases safety risks.

[0004] 2. When unloading mine cars by electric locomotives, especially tipper mine cars, the parking position of the mine car is required to be high. The electric locomotive needs to be slow and intermittent, and the miner needs to cooperate. The distance between the chute and the mine car is small, and the electric locomotive operator needs to repeatedly enter and exit the electric locomotive start and stop equipment. The electric locomotive operator assists in tipping the mine car to block the ore, which is inefficient.

[0005] 3. When transporting materials, especially large and heavy materials, electric locomotives need to be driven slowly to reduce the shaking of the transported materials. When turning, they need to be driven in short bursts to ensure the stability of the transported materials.

[0006] 4. When a mine car derails, there is usually only one locomotive operator in the transport roadway. Once a mine car or locomotive derails, the locomotive operator needs to use a rerailing device or padding to help reset it. This is usually done by one person. After padding the mine car wheels, the locomotive operator can not be sure if the padding mine car wheels are suitable. It usually takes several attempts to succeed, which is inefficient. Utility Model Content

[0007] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0008] Therefore, the purpose of this utility model is to provide an underground remote-controlled electric locomotive. By adding a remote control transmitter and receiver device to the electric locomotive's electrical control, the locomotive operator can remotely operate the locomotive from outside the vehicle, reducing the repeated adjustment time during loading and unloading of mine cars, and reducing labor costs and the risk of personnel being exposed to dangerous environments. At the same time, it can accurately control the locomotive, reduce the probability of mine car collisions and derailments, and extend the service life of the locomotive and track.

[0009] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0010] A remotely controlled underground electric locomotive, comprising:

[0011] The locomotive body is equipped with an electrical control system;

[0012] The wireless remote control transmitter module is connected to the electrical control system and is equipped with a forward button, a reverse button, and an emergency brake button.

[0013] A wireless receiver control module is installed on the locomotive body and is connected to the electrical control system signal.

[0014] The safety interlock module is connected to the locomotive body and is used to disable the remote control function when the locomotive is in a non-zero gear position.

[0015] The wireless receiving control module responds to the signal from the wireless remote control transmitting module and controls the locomotive body to perform inching or continuous slow operation.

[0016] As a preferred embodiment of the underground remote-controlled electric locomotive described in this utility model, the forward and reverse buttons are self-resetting buttons, short press triggers jogging mode, long press triggers continuous operation mode, and the emergency brake button triggers the mechanical braking system with higher priority than other control signals.

[0017] As a preferred embodiment of the underground remote-controlled electric locomotive described in this utility model, the safety interlock module includes a gear detection unit and an enable relay, which closes the control circuit when the gear is detected to be in the zero position.

[0018] As a preferred embodiment of the underground remote-controlled electric locomotive described in this utility model, the wireless remote control transmitter module is equipped with a status indicator light to display the locomotive's operating status and the remote control signal connection status.

[0019] As a preferred embodiment of the underground remote-controlled electric locomotive described in this utility model, the locomotive body has a built-in anti-collision module, which is used to allocate different communication frequency bands and codes when multiple remote-controlled electric locomotives are working simultaneously.

[0020] As a preferred embodiment of the underground remote-controlled electric locomotive described in this utility model, an emergency stop switch is provided outside the driver's cab of the locomotive body. The emergency stop switch is connected in parallel with the remote control system, and the locomotive body is equipped with an audible and visual alarm device that automatically starts when the remote control mode is activated.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] By adding remote control transmitters and receivers to the electric locomotive's electrical control system, locomotive operators can remotely control the locomotive from outside the vehicle, reducing the time spent on repeated adjustments during loading and unloading of mine cars, lowering labor costs and the risk of personnel being exposed to hazardous environments. At the same time, it enables precise control, reduces the probability of mine car collisions and derailments, and extends the service life of the locomotive and tracks.

[0023] When multiple vehicles are operating, the system can automatically switch frequency bands and automatically brake when the signal is lost or timeout occurs, improving system reliability. In case of derailment, a single person can complete the reset by remotely controlling the rerailing device without the need for multiple people to work together. Attached Figure Description

[0040] The safety interlock module includes a gear position detection unit and an enable relay, which closes the control circuit when the gear is detected to be in the zero position.

[0041] The wireless remote control transmitter module is equipped with status indicator lights to display the locomotive's operating status and the remote control signal connection status.

[0042] The electric locomotive has a built-in anti-collision module, which is used to allocate different communication frequency bands and codes when multiple remote-controlled electric locomotives are working at the same time.

[0043] An emergency stop switch is installed outside the cab of the locomotive. The emergency stop switch is connected in parallel with the remote control system.

[0052] Step 3: Insert the 25mm rerailing device as prompted, and press the forward button to complete the reset.

[0053] Working principle: When this utility model is used, a remote control transmitter and receiver device is added to the electric locomotive electrical control. The corresponding contactor for forward and reverse control can only be controlled when the locomotive is in the "zero" position.

[0054] Jog or press and hold the "Up" button: Electric locomotive pulls mine car;

[0055] Press and hold the "down" button: The electric locomotive reverses and tops the mine car;

[0056] Release the button: Exit control, and the locomotive will stop due to inertia;

[0057] Press and hold the "stop" button to apply the mechanical brake, and release the brake to reset it. This allows the locomotive operator to remotely control the machine from outside the vehicle, reducing the time spent on repeated adjustments during loading and unloading of mine cars, and also reducing labor costs and the risk of personnel being exposed to hazardous environments.
