由于攪拌機在相對惡劣的工地作業(yè)時，經常會出現(xiàn)爆胎的情況，因此攪拌機廠家總結了一種快速更換攪拌機輪胎的方法，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）先啟動機器，然后找一塊平坦開闊的場地，壓下動臂升降桿，用動臂支架使前輪離地，然后用支架支撐近閃橋一側穿刺，并把后輪楔好。

(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?lián)跞玩i緊環(huán)，然后檢查輪胎襯里和輪輞外表面是否貼合。如有發(fā)生，可拆下支撐，使機器在短距離內慢速往復運動，直墊塊與輪輞外表面分離；嚴禁轉向和高速行駛，以免損壞內胎。然后，前輪回升。

(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)標出內外胎的相對位置，以便發(fā)現(xiàn)異物，排除異物，修理輪胎。

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

(4)使用撬棍等工具將輪胎從輪輞上拆下。注意動作要輕柔默契，避免被輪胎傷到，保護氣門嘴。

(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）外胎被釘子等細長異物刺破后，如表面無明顯傷痕或傷痕小，可繼續(xù)使用外胎（因為攪拌機輪胎低-壓力輪胎和行駛速度相對較慢）；傷口大的話一定要修補（因為機器運轉時輪胎被擠壓和摩擦，久而久之會損壞內胎，甚傷口會越來越大，內胎會凸出來，而且輪胎會報廢。

(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)如果是新的內胎，必須擰緊閥門底部的螺栓，防止漏氣；然后外胎內腔的異物，撒上適量的滑石粉，涂抹均勻。為使內胎與內外胎緊密貼合，安裝內胎后應適當給內胎充氣，然后再插入內胎。

(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)將混凝土攪拌機輪胎裝到輪輞上，裝上鎖環(huán)和擋圈；在安裝過程中保護閥門。

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

(8)使用車載空氣壓縮機給輪胎充氣。

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

(9)壓下動臂提升桿，取出支架；此換胎完成，整個過程大約需要50分鐘。更換后輪胎時，需要另外的攪拌機或其他起重設備來支撐后輪胎，其他程序與更換前輪胎相同。

(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.
