Description
Technical Field

Background
Mining dump trucks are self-propelled machines that are used to transport materials or ore, travel in an underground mine, and lift and unload cargo by hydraulic or mechanical lift.
At present, slag of small and medium-sized ore enterprises mainly adopts a small amount of multi-time transportation, transportation tools mainly adopt small and simple transportation vehicles, and most transportation vehicles are not in line with the safety production requirements of mines although the transportation vehicles are various, and meanwhile, other problems exist:
(1) The engine is under-powered. Because the road surface roughness in the mine tunnel is relatively poor, the road surface is high and low, and when mineral is transported, the engine needs to run at high load all the time, and the running of the vehicle can be ensured, so that the fuel oil in the engine is insufficient in combustion, the fuel oil consumption rate is high, and meanwhile, the components of harmful substances in the waste gas of the engine can be increased, so that the airtight mine tunnel environment becomes worse, and the health of mine workers is seriously affected.
(2) No tail gas is purified, and the exhaust gas generated by the engine is discharged randomly, so that the environment is seriously polluted. Because the transport vehicle is used in a relatively airtight mine tunnel, the waste gas can cause great harm to the health of mine staff over time.
(3) The brake is usually an open dry brake, and water and dust are easy to enter the brake, so that the brake is out of order. Because the mine cavity is narrow and dark, once the brake fails, serious safety accidents are easily caused.
(4) A protection device for the driver is lacking. Because the transport vechicle automobile body overall dimension is big, and automobile body height is higher, can't move in a flexible way in narrow and small mine tunnel, so need cut or demolish the great driver's cabin of current, owing to do not have driver's cabin safety protection ceiling, the vehicle is gone in narrow and small, dark mine tunnel extremely easily causes the driver to receive various unexpected injuries.
(5) The warning device is absent. Vehicles run in complex and severe mine tunnel environments, and people and vehicles in an operation area cannot be warned when emergency or vehicle faults occur, so that potential safety hazards exist.
(6) No fire extinguisher is equipped on the vehicle. Because the mine cavity is generally high in temperature, the space is relatively airtight, and the vehicle is extremely easy to cause serious accident loss once being ignited and spontaneous combustion occurs.
(7) The steering system adopts mechanical transmission, and steering is laborious. When the vehicle is heavily loaded and driven on a mine road surface with larger fluctuation, the heavy mechanical steering system is more laborious to steer, the control intensity of a driver is increased, and fatigue driving is easy to cause.

The higher carriage front baffle plate can effectively prevent slag rocks from rolling down to the front of the car to hurt a driver in the process of loading or driving; the carriage with the bevel angle can enable the slag stone material to be dumped more completely; the two-section type tailgate 131 can be freely opened and closed according to the loading height change of the tail part, and the applicability of the vehicle is greatly improved.
The power system 2 mainly comprises a power device and a transmission device.
The power source in the power device adopts a supercharged intercooled diesel engine 21 for non-road, and the emission limit value accords with the third-stage emission standard of the diesel engine for the China non-road mobile machinery. The engine cooler 22 includes charge air cooling and engine closed forced circulation water cooling, among others. The application of the supercharging and intercooling technology on the dump truck can greatly improve the power and the torque on the basis of not increasing the engine displacement, so that the vehicle is more powerful. In addition, after the engine adopts the supercharging technology, the fuel economy can be improved, and the exhaust emission can be reduced. The high emission standard not only meets the national requirements, but also ensures that the emission of harmful substances is less in the running process of the dump truck, and the pollution to the air in the closed mine cavity is less.
The transmission 23 in the transmission consists of a main gearbox and an auxiliary gearbox. The gear of the main gearbox can be remotely switched through an operating lever arranged on the right side of the cab 12, one side of the main gearbox is provided with a power takeoff, and the combination and the separation of the power takeoff are realized through the switching of buttons arranged on an operating panel. The gear of the auxiliary gearbox can be switched at will according to actual needs through buttons arranged on the operation panel. The auxiliary gearbox is used to enable the vehicle to have larger power in a heavy load state; the power takeoff arranged at one side of the main gearbox can be directly provided with an oil pump to provide a power source for lifting the dumper.

An accumulator and a manual pump for releasing the brake are arranged in the brake system 3. The brake in the brake system 3 adopts a totally-enclosed multi-disc wet spring brake, and the brake belongs to a non-pressure safety brake. The manual pump in the brake system 3 can temporarily release the brake for the vehicle when the vehicle fails, so that the vehicle moves. The brake is of a fully-closed structure, so that the penetration of mud, water and oil can be prevented, and the brake is more stable; the wet brake is hydraulically driven, and oil liquid is circularly cooled, so that the wet brake has good heat dissipation performance, reduces maintenance and prolongs the service life.

The steering system and the lifting system are mutually independent, so that the lifting system which is not used frequently can be started only when needed, and the power consumption of the hydraulic system 5 is greatly reduced.
The steering hydraulic power can greatly lighten the steering strength, so that the steering is lighter. The lifting can greatly reduce the operation intensity through the remote control of the button. The lifting travel limit switch can effectively prevent the lifting oil cylinder from being damaged due to overlarge impact.
The tail gas purifying system 6 is mainly a water bath type purifying box 61, a plurality of layers of sieve plates and an interlayer are arranged in the structure of the water bath type purifying box 61, and the water bath type purifying box 61 is connected to the tail part of an exhaust pipe 62 of the diesel engine 21. The exhaust gas purification system 6 can comprehensively filter smoke dust and part of harmful substances in the engine exhaust, reduce environmental pollution and reduce harm to human health.
The safety protection system 7 mainly comprises a bumper 71 arranged at the front end of the vehicle body, a safety protection ceiling 121, warning lights, warning sounds and the like. The small dumper is provided with a portable dry powder fire extinguisher by pasting reflective stickers around the dumper. The arrangement of the bumper 71 can play a certain role in protecting the safety of a dump truck driver, and meanwhile, the warning light, the sound and the car body reflective sticker play a good role in warning mine operators.
The dump truck is provided with the fire extinguisher, so that the fire source can be processed at the first time when the dangerous situation occurs, and the possibility of property loss and human injury is reduced to the minimum.
