Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof auxiliary transport vehicles in underground coal mines, and in particular to a low-voltage electrical appliance digital control device for explosion-proof trackless rubber-wheeled vehicles for mines. Background Art

[0002] As an advanced modern coal mine underground auxiliary transportation equipment, explosion-proof rubber-tyred trackless vehicles are widely used. In the context of the country's promotion of intelligent mine construction, the intelligent digitalization requirements of explosion-proof rubber-tyred trackless vehicles are getting higher and higher, and the electrical system architecture is becoming more and more complex. However, the reversing radar system, imaging system, safety monitoring system, etc. used in current vehicles all use their own non-safe to intrinsically safe power supply, work independently and cannot interact, resulting in a relatively complex vehicle electrical system structure. At the same time, lighting control, horns, wipers, washing, reversing buzzers, start signals, defrosting and other functions are all controlled by flameproof switches or switch control devices. However, flameproof switches are large in size, heavy in weight, and difficult to arrange in the entire vehicle, resulting in poor ergonomics and cumbersome operation of the currently used explosion-proof rubber-tyred trackless vehicles, which increases the difficulty of operation for drivers. Summary of the invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a digital control device for low-voltage electrical appliances for explosion-proof trackless rubber-tyred vehicles for mining, to provide an integrated, lightweight, and efficient flameproof and intrinsically safe control system for explosion-proof trackless rubber-tyred transport vehicles in underground coal mines, and to perform systematic digital management and control of the low-voltage electrical appliances of the entire vehicle.

[0004] According to the technical solution provided in the embodiment of the present application, a low-voltage electrical digital control device for explosion-proof trackless rubber-wheeled vehicles for mining includes a flameproof and intrinsically safe signal control box for mining, the flameproof and intrinsically safe signal control box for mining is divided into a flameproof control chamber and an intrinsically safe wiring chamber, an isolation signal control module is arranged in the flameproof control chamber, and a flameproof housing and a flameproof joint surface are adopted to realize flameproofing, a plurality of flameproof cable introduction devices are arranged on the side end face of the flameproof control chamber, which are used for introducing the flameproof cables of flameproof associated equipment; the intrinsically safe wiring chamber adopts an intrinsically safe design, a plurality of intrinsically safe connectors are arranged on the outer end face of the wiring chamber, the intrinsically safe cables of the intrinsically safe associated equipment are connected, and a partition is arranged between the flameproof control chamber and the intrinsically safe wiring chamber, and a through hole is arranged on the partition, and a flameproof wiring terminal is installed to complete the electrical connection between the chambers;

[0005] The mine-use intrinsically safe display screen is connected to the intrinsically safe connector on the wiring cavity through an intrinsically safe cable and is used to display the vehicle operation status information.

[0006] Furthermore, several intrinsically safe connectors are respectively connected to mine intrinsically safe temperature sensors, mine intrinsically safe pressure sensors, mine intrinsically safe proximity switches, mine flameproof electromagnetic reversing valves, mine intrinsically safe locomotive combination control switches, mine flameproof locomotive lights, mine intrinsically safe reversing radar imaging systems, mine flameproof and intrinsically safe sound and light signalers, and mine intrinsically safe auxiliary lighting lamps through intrinsically safe cables.

[0007] Furthermore, mine intrinsically safe temperature sensors, mine intrinsically safe pressure sensors, mine intrinsically safe proximity switches, mine flameproof electromagnetic reversing valves, mine intrinsically safe locomotive combination control switches, mine flameproof locomotive lights, mine intrinsically safe reversing radar imaging systems, mine flameproof and intrinsically safe sound and light signalers, and mine intrinsically safe auxiliary lighting lamps are all connected to the mine intrinsically safe display screen through an isolated signal control module.

[0008] Furthermore, the isolation signal control module in the mine-use flameproof and intrinsically safe signal control box is connected to the mine-use intrinsically safe display screen through the vehicle CAN bus communication network.

Several flameproof cable introduction devices 2 are arranged outside the flameproof control chamber 101, an isolation signal control module is arranged inside the flameproof control chamber 101, an intrinsically safe connector 4 is arranged on the intrinsically safe wiring chamber 102, and a partition is provided between the flameproof control chamber and the intrinsically safe wiring chamber, and a through hole is arranged on the partition, and a flameproof wiring terminal is installed to complete the electrical connection between the chambers;

[0023] Among them, the isolation signal control module specifically includes a non-intrinsically safe control module, an electrical isolation module and a non-intrinsically safe and intrinsically safe power conversion module.

[0024] Among them, the non-intrinsically safe control module of the mine-use explosion-proof and intrinsically safe signal control box can directly introduce explosion-proof cables for communication, power supply and control of explosion-proof associated equipment through the explosion-proof cable introduction device on the explosion-proof control chamber, or it can realize signal conversion, transmission and isolation between intrinsically safe and non-safe circuits through the electrical isolation module, and then be connected to the intrinsically safe connector via the explosion-proof terminal blocks installed on the partition between the explosion-proof control chamber and the intrinsically safe wiring chamber, and external intrinsically safe cables can be used for communication, power supply and control of intrinsically safe associated equipment.

[0025] Among them, the non-intrinsically safe control module and the non-intrinsically safe to intrinsically safe power supply conversion module of the mine-use explosion-proof and intrinsically safe signal control box can directly communicate, power supply and control each other. The non-intrinsically safe to intrinsically safe power supply conversion module is provided with multiple non-intrinsically safe power supply output ports and multiple intrinsically safe power supply output ports. The non-intrinsically safe power supply output port can supply non-intrinsically safe power to the explosion-proof associated equipment through the explosion-proof cable directly introduced by the explosion-proof cable introduction device on the explosion-proof control chamber. The intrinsically safe power supply output port is connected to the intrinsically safe connector via the explosion-proof terminal installed on the partition between the explosion-proof control chamber and the intrinsically safe wiring chamber, and the external intrinsically safe cable supplies intrinsically safe power to the intrinsically safe associated equipment.

The driver can understand the vehicle operation status through the interface display information of the mine intrinsically safe display screen 6;

[0032] When the isolated signal control module in the mine flameproof and intrinsically safe signal control box 1 detects abnormal status information of each system, it sends information through the vehicle CAN bus communication network and sends it to the vehicle's mine intrinsically safe display screen.

If the vehicle is monitored to be driving and the rear door or the left and right doors of the cab are not closed, the isolation signal control module of the mine-use flameproof and intrinsically safe signal control box 1 will send information through the vehicle's CAN bus communication network to the vehicle's mine-use intrinsically safe display screen 6 to display the rear door or the left and right doors of the cab are not closed. The door warning symbol will be sent, and an audible and visual alarm will be issued to remind the vehicle personnel to pay attention to closing the door.
