小型混凝土搅拌车如何更换轮胎？下面跟随小型混凝土搅拌车厂家一起来了解一下吧。
How to change the tires of a small concrete mixer truck? Let's follow the manufacturers of small concrete mixer trucks to learn more.
1、启动机器，近寻找一块比较平坦开阔的场地，压下动臂升降杆，利用动臂支承使前轮离地，然后用支架支撑在闪桥靠近爆胎的一侧，并将后轮楔好(必须与驾驶员密切配合，以免造成人身伤害)。
1. Start the machine, search for a relatively flat and open area, press down on the boom lifting rod, use the boom support to lift the front wheels off the ground, and then use a bracket to support the side of the flash bridge near the tire burst, and wedge the rear wheels (close cooperation with the driver is necessary to avoid personal injury).
2、利用撬杠等等工具，拆卸挡圈及锁圈然后检查轮胎衬垫与轮辋外表面是否粘连(轮胎使用时间较长，衬垫与轮辋外表面可发生粘连)。若发生可撤掉支撑物，使机器在短距离内慢速往复运行，直衬垫与轮辋外表面脱离；严禁转向和高速行驶，以免损坏内胎。然后，前轮重新支撑起来。
2. Use pry bars and other tools to remove the retaining ring and lock ring, and then check if the tire pad adheres to the outer surface of the rim (if the tire is used for a long time, the pad may adhere to the outer surface of the rim). If there is a problem, the support can be removed, allowing the machine to run slowly back and forth over a short distance until the pad detaches from the outer surface of the wheel rim; It is strictly prohibited to turn and drive at high speeds to avoid damaging the inner tube. Then, the front wheels are supported again.
3、将内、外胎的相对位置作好标记，以便查找、异物和修补轮胎。
3. Mark the relative positions of the inner and outer tires for easy identification, removal of foreign objects, and tire repair.
4、利用撬杠等工具，将轮胎从轮辋上拆下。注意，动作要轻柔配合要默契，避免被轮胎砸伤，并且要保护好气门嘴。
4. Use tools such as a pry bar to remove the tire from the rim. Attention, the movements should be gentle and harmonious, to avoid being hit by tires, and to protect the valve mouth.
5、外胎被钉子等细长异物扎伤后，若表面无明显创口或创口较小，则此外胎可继续使用(因为小型混凝土搅拌车轮胎属低压胎，且运行速度比较慢)；若创口较大，则必须进行修补(因为机器运行时，轮胎受挤压磨擦，时间一长会损坏内胎，甚创口越来越大、内胎突出，造成轮胎报废)。
5. After the outer tire is punctured by slender foreign objects such as nails, if there is no obvious wound on the surface or if the wound is small, the outer tire can continue to be used (because the small concrete mixer tire is a low-pressure tire and the running speed is relatively slow); If the wound is large, it must be repaired (because during machine operation, the tire is compressed and rubbed, which can damage the inner tube over time, and even cause the wound to become larger and the inner tube to protrude, causing the tire to be scrapped).
6、若是新内胎，必须将气门嘴底部的螺栓拧紧，以防漏气；然后将外胎内腔的异物，并撒入适当的滑石粉，涂抹均匀。为了使衬垫与内、外胎贴紧，在装入内胎后应给内胎适当充气，再塞入衬垫。
6. If it is a new inner tube, the bolts at the bottom of the valve must be tightened to prevent air leakage; Then remove any foreign objects from the inner cavity of the outer tire, sprinkle appropriate talcum powder, and apply evenly. In order to make the liner tightly adhere to the inner and outer tires, the inner tire should be appropriately inflated after being installed, and then the liner should be inserted.
7、将轮胎装到轮辋上，装上锁圈、挡圈；安装过程中要保护好气门嘴。
7. Install the tire onto the rim and install the lock ring and retaining ring; During the installation process, it is necessary to protect the gas valve mouth.
8、用车载空压机给轮胎充气。
8. Use a car mounted air compressor to inflate the tires.
9、压下动臂升降杆，取出支架；此换胎完毕，整个过程大约需要50min。更换后轮胎时，则需要另一台小型混凝土搅拌车或者其他起重设备辅助，将后轮胎支撑起来，其他程序则与更换前轮胎相同。
9. Press down the boom lifting rod and take out the bracket; At this point, the tire change is complete, and the entire process takes approximately 50 minutes. When replacing the rear tire, another small concrete mixer truck or other lifting equipment is needed to support the rear tire, and the other procedures are the same as before replacing the front tire.
