由于搅拌机在相对恶劣的工地作业时，经常会出现爆胎的情况，因此搅拌机厂家总结了一种快速更换搅拌机轮胎的方法，如下：

Because the mixer often has a flat tire when working on a relatively poor site, the mixer manufacturer has summarized a method to quickly replace the mixer tire, as follows:

（1）先启动机器，然后找一块平坦开阔的场地，压下动臂升降杆，用动臂支架使前轮离地，然后用支架支撑近闪桥一侧穿刺，并把后轮楔好。

(1) First start the machine, then find a flat and open place, press down the boom lifting rod, use the boom support to lift the front wheel off the ground, and then use the support to support the puncture near the flash Bridge side, and wedge the rear wheel.

（2）用撬棒等工具拆下挡圈和锁紧环，然后检查轮胎衬里和轮辋外表面是否贴合。如有发生，可拆下支撑，使机器在短距离内慢速往复运动，直垫块与轮辋外表面分离；严禁转向和高速行驶，以免损坏内胎。然后，前轮回升。

(2) Remove the retaining ring and locking ring with a crowbar and other tools, and then check whether the tire lining fits the outer surface of the rim. If it happens, the support can be removed to make the machine move back and forth slowly in a short distance until the cushion block is separated from the outer surface of the rim; It is strictly forbidden to turn and drive at high speed to avoid damaging the inner tube. Then, the front wheels pick up.

(3)标出内外胎的相对位置，以便发现异物，排除异物，修理轮胎。

(3) Mark the relative position of the inner and outer tires so that foreign matters can be found, eliminated and repaired.

(4)使用撬棍等工具将轮胎从轮辋上拆下。注意动作要轻柔默契，避免被轮胎伤到，保护气门嘴。

(4) Use tools such as crowbars to remove the tire from the rim. Pay attention to the gentle and tacit action to avoid being injured by the tire and protect the valve.

（5）外胎被钉子等细长异物刺破后，如表面无明显伤痕或伤痕小，可继续使用外胎（因为搅拌机轮胎低-压力轮胎和行驶速度相对较慢）；伤口大的话一定要修补（因为机器运转时轮胎被挤压和摩擦，久而久之会损坏内胎，甚伤口会越来越大，内胎会凸出来，而且轮胎会报废。

(5) After the outer tube is punctured by slender foreign bodies such as nails, if there is no obvious scar on the surface or the scar is small, you can continue to use the outer tube (because the mixer tire is low - the pressure tire and the driving speed are relatively slow); If the wound is large, it must be repaired (because the tire is squeezed and rubbed during the operation of the machine, and the inner tube will be damaged over time, and even the wound will become larger and larger, the inner tube will protrude, and the tire will be scrapped.

(6)如果是新的内胎，必须拧紧阀门底部的螺栓，防止漏气；然后外胎内腔的异物，撒上适量的滑石粉，涂抹均匀。为使内胎与内外胎紧密贴合，安装内胎后应适当给内胎充气，然后再插入内胎。

(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 the foreign matters in the inner cavity of the outer tube, sprinkle an appropriate amount of talc powder, and apply it evenly. In order to make the inner tube closely fit the inner and outer tubes, inflate the inner tube appropriately after installing the inner tube, and then insert the inner tube.

(7)将混凝土搅拌机轮胎装到轮辋上，装上锁环和挡圈；在安装过程中保护阀门。

(7) Install the concrete mixer tire on the rim, and install the lock ring and retaining ring; Protect the valve during installation.

(8)使用车载空气压缩机给轮胎充气。

(8) Use the on-board air compressor to inflate the tires.

(9)压下动臂提升杆，取出支架；此换胎完成，整个过程大约需要50分钟。更换后轮胎时，需要另外的搅拌机或其他起重设备来支撑后轮胎，其他程序与更换前轮胎相同。

(9) Press down the boom lifting rod and take out the support; So far, the tire change is completed, and the whole process takes about 50 minutes. When replacing the rear tire, another mixer or other lifting equipment is required to support the rear tire, and other procedures are the same as those of replacing the front tire.
