搅拌车维修过程中常见的几种安全隐患

作者:http://www.zkzsljbc.com 时间:2022-06-13

轮胎鼓胀和开裂
Tire bulging and cracking
鼓包形成后轮胎的压缩能力会变得非常不均匀,因此应及时用轮胎拆卸机更换轮胎。许多轮胎爆炸是由于维修人员用撬棍或其他工具敲击轮胎鼓造成的。搅拌车的大胎压为10kg/cm2,相当于30层楼高水柱底部的压力。假设轮胎气压为每平方厘米5公斤,气体瞬间爆炸。短距离内产生的冲击波足以击碎人体骨骼。
After the bulge is formed, the compression capacity of the tire will become very uneven, so the tire should be replaced with a tire remover in time. Many tire explosions are caused by maintenance personnel hitting the tire drum with crowbars or other tools. The large tire pressure of the mixer truck is 10kg/cm2, which is equivalent to the pressure at the bottom of the 30 story high water column. Assuming that the tire pressure is 5 kg per square centimeter, the gas will explode instantly. The shock wave generated in a short distance is enough to break human bones.
小心使用辅助起动开关
Use the starting aid switch carefully
维修时经常使用自动上料搅拌车上的辅助起动开关。但是,当辅助起动开关短路时,必须确保变速箱处于空档,否则卡车将挂档行驶,如果驾驶室没有司机,将造成严重后果。
The auxiliary start switch on the automatic feeding mixer is often used during maintenance. However, when the auxiliary start switch is short circuited, it must be ensured that the transmission is in neutral, otherwise the truck will drive in gear. If there is no driver in the cab, serious consequences will be caused.
虽然有些发动机ECU需要接收空档开关信号,但有些型号的空档开关仍然短路,因此建议在使用辅助起动开关时检查档位。随着电控发动机的普及,发动机的维修变得越来越复杂,油管接头的拆卸需要更加细致的操作。
Although some engine ECUs need to receive the neutral switch signal, some models of neutral switch are still short circuited. Therefore, it is recommended to check the gear when using the auxiliary start switch. With the popularization of electronic control engine, the maintenance of engine becomes more and more complex, and the disassembly of oil pipe joint needs more careful operation.
配备高压共轨的柴油机工作时,大内部燃油压力可达2000巴以上。产生的压力相当于搅拌车压在钉板上。如果伤人,后果不堪设想。好的方法是等待发动机完全停止并完成泄压,然后拆下油管。
When the diesel engine equipped with high-pressure common rail works, the internal fuel pressure can reach more than 2000 bar. The generated pressure is equivalent to the pressure of the mixer on the nail plate. If you hurt people, the consequences will be unimaginable. A good method is to wait for the engine to stop completely and complete the pressure relief, and then remove the oil pipe.
自动上料搅拌车
随意打开水箱盖有隐患
Open the water tank cover at will, which has hidden dangers
发动机过热运行,散热效率差,会造成水箱发热甚至沸腾。此时要避免立即熄火(熄火后散热器会停止工作),找一个安全的地方停车,保持发动机怠速运转,以充分散热。
The engine is overheated and the heat dissipation efficiency is poor, which will cause the water tank to heat up or even boil. At this time, avoid immediate flameout (the radiator will stop working after flameout), find a safe place to stop, and keep the engine idling to fully dissipate heat.
在水箱温度降到安全水平之前,不要打开水箱盖,否则会喷出未冷却的液体。正确的方法是用湿毛巾包住水箱盖,慢慢打开第一个开关(约1/4圈),待蒸汽压力完全释放后再打开水箱盖。
Do not open the water tank cover before the water tank temperature drops to a safe level, otherwise uncooled liquid will be ejected. The correct method is to wrap the water tank cover with a wet towel, slowly open the first switch (about 1/4 turn), and then open the water tank cover after the steam pressure is completely released.
注意轮胎的正确安装方法。
Pay attention to the correct installation method of the tire.
安装轮胎时,应尽量使用专用工具,并在安全的环境下操作。一些专车司机担心安装轮胎时螺丝不够牢固。他们经常用撬棍把它固定住。这不仅会损坏螺钉,而且撬杆反弹可能会伤害操作员。
When installing the tire, try to use special tools and operate in a safe environment. Some special bus drivers worry that the screws are not firm enough when installing tires. They often fix it with crowbars. Not only will this damage the screws, but the rebound of the crowbar may harm the operator.
驾驶室的提升不应含糊不清
The lifting of the cab shall not be ambiguous
自动上料搅拌车的发动机维修过程中,经常需要将驾驶室提升和翻转。在操作过程中,不得将驾驶室提升到末端。装置不能工作,可能在外力作用下坠落。如果有人员在发动机位置,将会造成无法修复的损坏。
During the engine maintenance of the automatic loading mixer, it is often necessary to lift and turn over the cab. Do not lift the cab to the end during operation. The device cannot work and may fall under the action of external force. If someone is in the engine position, irreparable damage will be caused.
