When loading concrete, if the mixer truck fails, the mixing drum cannot rotate, and the concrete in the mixing drum shall be discharged quickly.

連接緊急驅(qū)動軟管，依靠其它攪拌車的動力，驅(qū)動拌筒旋轉(zhuǎn)并將混凝土排出。但是若減速器同時發(fā)生故障時，則不可采用此法。

Connect the emergency drive hose and drive the mixing drum to rotate and discharge the concrete with the power of other mixer trucks. However, if the reducer fails at the same time, this method can not be used.

具體操作步驟如下：準備好一根緊急驅(qū)動軟管，卸下接管和接頭蓋。故障車（被驅(qū)動車）的操作：將故障車的發(fā)動機熄火；將緊固螺母（左右各有一個）朝左旋松；再將旋鈕朝右旋轉(zhuǎn)，直到不能再旋為止；將高壓軟管從馬達接頭處卸下；將緊急驅(qū)動軟管接到馬達接頭上；把緊急驅(qū)動軟管上的接管與故障車卸下的高壓軟管相接，以防漏油。

The specific operation steps are as follows: prepare an emergency drive hose, and remove the nozzle and connector cover. Operation of the fault vehicle (driven vehicle): turn off the engine of the fault vehicle; loosen the fastening nut (one on the left and one on the left) to the left; then turn the knob to the right until it can't be rotated again; remove the high-pressure hose from the motor connector; connect the emergency drive hose to the motor connector; connect the connecting the fault vehicle Oil leakage.

自動上料攪拌車的應急處理方式

救援車（驅(qū)動車）的操作：將操作手柄至于空檔位置；將發(fā)動機熄火；將高壓軟管從高壓油管處卸下；將緊急驅(qū)動軟管接到高壓油管上；用緊急驅(qū)動軟管上的接頭蓋將驅(qū)動車的高壓軟管蓋起，以防漏油。啟動救援車的發(fā)動機；將救援車的操作手柄撥至“出料”位置，使故障車內(nèi)的混凝土排出；緊急驅(qū)動完畢后，使兩車各自恢復原狀。

Operation of rescue vehicle (driving vehicle): set the operating handle to the neutral position; turn off the engine; remove the high-pressure hose from the high-pressure oil pipe; connect the emergency drive hose to the high-pressure oil pipe; cover the high-pressure hose of the driving vehicle with the joint cover on the emergency drive hose to prevent oil leakage. Start the engine of the rescue vehicle; turn the operation handle of the rescue vehicle to the "discharge" position to discharge the concrete in the fault vehicle; after the emergency drive is completed, make the two vehicles return to their original state.

除上述方法外，或者打開拌筒檢修孔的孔蓋，旋松高壓軟管的管接頭，將混凝土從拌筒檢修孔內(nèi)排出。注意：放松管接頭時，拌筒往往會因此做急速運轉(zhuǎn)，可在拌筒的托輪與滾道之間放入木楔，使拌筒停止轉(zhuǎn)動。

In addition to the above methods, or open the manhole cover of the mixing drum, loosen the pipe joint of the high-pressure hose, and discharge the concrete from the manhole of the mixing drum. Note: when loosening the pipe joint, the mixing drum will often run rapidly. A wooden wedge can be placed between the roller and the raceway to stop the drum from rotating.

安裝新的柱塞泵，使拌筒恢復正常運轉(zhuǎn)，從而將混凝土排出；打開拌筒檢修孔孔蓋，卸下柱塞泵，將混凝土從拌筒檢修孔內(nèi)排出。注意：放松管接頭時，拌筒往往會因此做急速運轉(zhuǎn)，可在拌筒的托輪與滾道之間放入木楔，使拌筒停止轉(zhuǎn)動。

Install a new plunger pump to return the mixing drum to normal operation, so as to discharge the concrete; open the manhole cover of the mixing drum, remove the plunger pump, and discharge the concrete from the manhole of the mixing drum. Note: when loosening the pipe joint, the mixing drum will often run rapidly. A wooden wedge can be placed between the roller and the raceway to stop the drum from rotating.
