In the process of tunnel construction, outstanding ventilation conditions and construction environment are the necessary conditions to ensure normal construction. After the explosion in the tunnel, the smoke and dust are harmful, and the machinery will also produce exhaust gas containing oil smoke and toxic gases during the work. These smoke and exhaust gas not only endanger the health of the operator, but also affect the normal operation of the wheel loader Together, it will affect the vision of the operator and cause safety incidents. At present, most of the tunnel construction uses a ventilator to replace the air in the surface of the tunnel. The choice of the ventilator should be decided according to the size and length of the tunnel section and the external ventilation status of the tunnel entrance. After all, the role of the operator of wheel loader will not be bored in the operation, and the lack of intake air will not appear when the engine of the side unloading wheel loader is in operation. If the ventilation is poor, various smoke and dust in the hole cannot be discharged in time, and the re-inhalation of exhaust gas will form into the wheel loader. The power of the engine is reduced due to the lack of intake air, and the exhaust emits black smoke. Carbon deposits shorten the service life of the engine. In addition, inventing an outstanding working environment is also an important aspect to ensure the normal operation of the side-loading wheel loader. It includes the risk control of the working surface before the wheel loader enters the hole, and outstanding lighting equipment. These methods help reduce the outside world. The reason for the damage to the wheel loader and its collision with the cave wall and other working machinery during the operation.
Protect and maintain side-loading wheel loaders in time
Loader repair
Because the working environment of the side-loading wheel loader in the tunnel construction is relatively harsh, its protection and maintenance operations should also be in place in time. The air quality in the tunnel is much worse than in the open air. The air is more humid and contains more dust and oil smoke. This will greatly affect the intake quality of the side loader engine and greatly shorten the service life of the air filter , Especially for paper filter elements, the engine will emit black smoke and the vehicle is weak when severe. Replacing the air filter element in time according to the actual situation will help extend the service life of the side-loading wheel loader engine and ensure the normal overhaul cycle of the engine. We must also monitor the quality of engine oil, hydraulic transmission oil, and hydraulic oil at any time, and replace new oil, replace filter elements, or clean filter screens in time according to their transformation status. Because the harsh operating environment will accelerate the transformation of the oil, its performance indicators can not meet the requirements of smoothness and cooling, and the parts will be damaged in severe cases. It is necessary to do a good job in cleaning all parts of the side unloading wheel loader. A lot of dust tends to accumulate in the gaps of the radiator fins, because the environment is relatively wet, the dust will become wet mud and adhere to the fins, so that the engine can not dissipate heat normally, and it will cause abnormal heating of the engine when severe, so that the side unload The steel loader cannot work normally. In addition, the mixture of oil and dust adhering to the engine block and transmission case will also affect the heat dissipation of these components. Vent holes are provided on the engine crankcase, hydraulic oil tank, fuel tank and axle of the side unloading wheel loader to prevent the internal pressure of the air in these tanks from increasing due to thermal expansion, affecting normal operation. Blocking of these vents will cause the oil in the tank to overflow or cause the oil to foam and morph. Therefore, the filters of these vents should be cleaned in time to keep them clear. The smooth grease at each hinged part of the side unloading wheel loader is also a major point of protection and maintenance operations. These parts should be regularly filled with smooth grease to prevent abnormal wear. When adding smooth grease, the old grease mixed with dust and gravel should be removed to avoid such impurities from entering the conflict surface.
