Technical Field

[0001] This utility model relates to the field of support transport vehicles, and more particularly to the engine electronic control device of a frame-type support transport vehicle. Background Technology

[0002] Support transport vehicles refer to all vehicle-type equipment that can transport support products involved in various social production and business activities. However, they are mostly used for the relocation or long-distance transportation of hydraulic supports during the relocation of fully mechanized mining faces in mining areas. The engine and electronic control device of the frame-type support transport vehicle is the core system that ensures its power output, safety and environmental adaptability.

[0003] The existing frame-type support transport vehicle has a relatively complex engine electronic control device structure, which makes maintenance inconvenient and makes it impossible to repair in a timely manner when a failure occurs, which seriously hinders the construction progress. Utility Model Content

[0004] In order to overcome the problem that the existing frame-type support transport vehicle has a relatively complex engine electronic control device structure, which makes maintenance inconvenient and makes it impossible to repair in time when a failure occurs, thus seriously hindering the construction progress.

[0005] The technical solution of this utility model is: an engine electronic control device for a frame-type support transport vehicle, including an electronic control host and a sensor assembly, as well as an accelerator pedal and a fuel injector. The electronic control host is provided with a circuit board structure, and the electronic control host and the sensor assembly are electrically connected.

[0006] The sensor assembly includes a mine-use cast-type high-pressure oil pump electromagnet, a mine-use cast-type fuel injection solenoid valve, a mine-use cast-type intake pressure sensor, a mine-use cast-type intake temperature sensor, a mine-use cast-type cooling water temperature sensor, a mine-use cast-type rail pressure sensor, a mine-use cast-type crankshaft speed sensor, a mine-use cast-type cam speed sensor, a mine-use intrinsically safe oil pressure sensor, and a mine-use intrinsically safe pedal position sensor. The mine-use cast-type high-pressure oil pump electromagnet and the fuel injector are connected through an oil pipeline. Four mine-use cast-type fuel injection solenoid valves are installed on the oil pipeline.

[0007] Preferably, multiple sensors can monitor engine parameters and transmit them to the electronic control unit in real time, making it convenient for personnel to view and detect the engine status, determine the engine's working status, and control the engine's safe operation. This avoids situations where the original vehicle system design is too complex, causing equipment to falsely report faults and shut down, thus restricting production and improving practicality.

[0008] Preferably, the electronic control unit is connected to the vehicle computer via a CAN-to-USB cable, and the vehicle computer is equipped with a display screen.

[0009] As a preferred option, both the mine-use encapsulated intake pressure sensor and the mine-use encapsulated intake temperature sensor are installed on the intake pipe.

[0010] Preferably, the mine-use encapsulated cooling water temperature sensor is installed in the cooling water tank, and the mine-use encapsulated rail pressure sensor is installed on the support rail.

[0011] Preferably, the mining-grade encapsulated crankshaft speed sensor is located on the side of the crankshaft rod, and the mining-grade encapsulated cam speed sensor is located on the side of the cam.

[0012] As a preferred option, the intrinsically safe oil pressure sensor for mining applications is installed on the oil tank.

[0013] Preferably, the intrinsically safe pedal position sensor for mining is mounted on the accelerator pedal, and the accelerator pedal controls the engine output.

[0014] The beneficial effects of this utility model are:

[0015] The engine electronic control unit of this frame-type support transport vehicle collects engine operating status information through various sensors installed on the engine. After data processing, it selects the optimal operating curve and controls the opening time and injection quantity of the fuel injectors. When the engine malfunctions, it issues a warning signal and takes corresponding measures, including stopping the engine if necessary. It also uses software to diagnose engine faults and can receive accelerator pedal signals to understand the driver's intentions, thereby controlling the engine fuel injectors and regulating the engine speed and output. This successfully avoids the situation where the original vehicle system design is too complex, causing the equipment to falsely report faults and stop, thus restricting production.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-3 The present invention provides an embodiment of an engine electronic control device for a frame-type support transport vehicle, which includes an electronic control host 1 and a sensor assembly, as well as an accelerator pedal 2 and a fuel injector 3. The electronic control host 1 is provided with a circuit board structure, and the electronic control host 1 and the sensor assembly are electrically connected.

[0022] The sensor assembly includes a mining-grade encapsulated high-pressure oil pump electromagnet 4, a mining-grade encapsulated fuel injection solenoid valve 5, a mining-grade encapsulated intake pressure sensor 6, a mining-grade encapsulated intake temperature sensor 7, a mining-grade encapsulated cooling water temperature sensor 8, a mining-grade encapsulated rail pressure sensor 9, a mining-grade encapsulated crankshaft speed sensor 10, a mining-grade encapsulated cam speed sensor 11, a mining-grade intrinsically safe oil pressure sensor 12, and a mining-grade intrinsically safe pedal position sensor 13. The mining-grade encapsulated high-pressure oil pump electromagnet 4 and the fuel injector 3 are connected via oil pipelines. The pipeline is equipped with four mining-grade castable fuel injection solenoid valves 5. The electronic control host 1 is connected to the vehicle computer via a CAN-to-USB cable. The vehicle computer has a display screen and can monitor engine parameters through multiple sensors, which are transmitted to the electronic control host 1 in real time. This allows personnel to view and detect the engine status, determine the engine's working condition, and control the engine's safe operation. This avoids situations where the original vehicle system design is too complex, leading to false alarms and shutdowns that restrict production, thus improving practicality.

[0023] Please see Figure 1 and Figure 2In this embodiment, the mine-use cast-type intake pressure sensor 6 and the mine-use cast-type intake temperature sensor 7 are both installed on the intake pipe; the mine-use cast-type coolant temperature sensor 8 is installed in the coolant tank; the mine-use cast-type rail pressure sensor 9 is installed on the support rail; the mine-use cast-type crankshaft speed sensor 10 is located on the side of the crankshaft; the mine-use cast-type cam speed sensor 11 is located on the side of the cam; the mine-use intrinsically safe oil pressure sensor 12 is installed on the oil tank; and the mine-use intrinsically safe pedal position sensor 13 is installed on the accelerator pedal 2. Pedal 2 controls the engine output. Different sensors are installed in different locations inside the vehicle to monitor data such as engine surface temperature, coolant level, coolant temperature, exhaust temperature, oil pressure, and engine speed in real time, and display them on the computer screen. Software is used to diagnose engine faults. In addition, it can receive signals from accelerator pedal 2 to understand the driver's intentions, and then control the engine fuel injectors 3 to regulate engine speed and output. This successfully avoids the situation where the original vehicle system design is too complicated, causing the equipment to falsely report faults and stop, thus restricting production.

[0024] During operation, different sensors are installed in different locations inside the vehicle to monitor data such as engine surface temperature, coolant level, coolant temperature, exhaust temperature, oil pressure, and engine speed in real time, and display them on the computer screen simultaneously. When an engine malfunctions, a warning signal is issued, and corresponding measures are taken, including stopping the engine if necessary. It can connect to the computer via a CAN-to-USB cable to diagnose engine malfunctions using software. In addition, it can receive signals from the accelerator pedal to understand the driver's intentions and then control the engine fuel injectors to regulate engine speed and output. This successfully avoids the situation where the original vehicle system design is too complex, causing the equipment to falsely report malfunctions and shut down, thus restricting production.

[0025] Through the above steps, multiple sensors can monitor engine parameters and transmit them to the electronic control host 1 in real time. This allows personnel to view and detect the engine status, determine the engine's working condition, and control the engine's safe operation. This avoids the situation where the original vehicle system design is too complex, causing the equipment to falsely report faults and shut down, thus restricting production. It improves practicality and solves the problem that the existing frame-type support transport vehicle's engine electronic control device structure is relatively complex, resulting in inconvenient maintenance and inability to repair in time when a fault occurs, which seriously hinders the construction progress.
