斗式提升機(jī)料斗帶打滑的處理方法：
(1)斗式提升機(jī)是利用料斗帶與頭輪傳動(dòng)軸間的摩擦力矩來進(jìn)行升運(yùn)物料的，叵料斗帶張力不夠，將導(dǎo)致料斗帶打滑。這時(shí)，應(yīng)立即停機(jī)，調(diào)節(jié)張緊裝置以拉緊料斗帶。若張緊裝置不能使料斗帶完全張緊，說明張緊裝置的行程太短，應(yīng)重新調(diào)節(jié)。
正確的解決方法是：解開料斗帶接頭，使底輪上的張緊裝置調(diào)至最高位置，將料斗帶由提升機(jī)機(jī)頭放入，穿過頭輪和底輪，并首尾連接好，使料斗帶處于將張緊而未張緊的狀態(tài)。然后使張緊裝置完全張緊。此時(shí)張緊裝置的調(diào)節(jié)螺桿尚未利用的張緊行程不應(yīng)小于全行程的50%。
(2)提升機(jī)超載提升機(jī)超載時(shí)，阻力矩增大，導(dǎo)致料斗帶打滑。此時(shí)應(yīng)減小物料的喂入量，并力求喂料均勻。若減小喂入量后，仍不能改善打滑，則可能是機(jī)坐內(nèi)物料堆積太多或料斗被導(dǎo)師物卡住，應(yīng)停機(jī)檢查，排除故障。
(3)頭輪傳動(dòng)軸和料斗帶內(nèi)表面過于光滑頭輪傳動(dòng)軸和料斗帶內(nèi)表面過于光滑，使兩者間的摩擦力減小，導(dǎo)致料斗帶打滑。這時(shí)，可在傳動(dòng)軸和料斗帶內(nèi)表面涂一層膠，以增大摩擦力。
(4)頭輪和底輪軸承轉(zhuǎn)動(dòng)不靈頭輪和底輪軸承轉(zhuǎn)動(dòng)不靈，阻力矩增大，引起料斗帶打滑。這時(shí)可拆洗加油或更換軸承。
中譯英：
(1) the bucket hoist is the use of hopper band and the head wheel shaft friction torque for lifting material hopper, belt tension of not enough, will lead to a hopper belt. At this time, should immediately stop, adjustable tensioning device for tensioning hopper band. If the tensioning device can not cause the hopper with fully tensioned, illustrate the tensioning device range is too short, should be adjusted.
The right solution is : unraveling the hopper belt joint, so that the bottom wheel tensioning device to the highest position, the hopper band by lifting machine head in, through the head wheel and the wheels, and are connected end to end, with the hopper in the tension without tension state. Then the tensioning device fully tensioned. The tensioning device of the regulating screw not utilized by the tensioning stroke shall be not less than the full stroke 50%.
(2) hoist overload hoist overload, increase of resistance moment, causing the hopper belt. This should reduce the material feeding quantity, and even feeding. If reduce the feeding amount, still can not improve the skid, may be sitting in the material piling machine too much or hopper by the tutor matter stuck, should be down to check, troubleshooting.
(3) head wheel shaft and a hopper with inner surface too smooth head wheel shaft and a hopper with inner surface too smooth, so that both the friction is reduced, leading to a hopper belt. Then, in the drive shaft and a hopper with an inner surface coated with a layer of glue, to increase the friction force.
(4) the head wheel and the bottom wheel bearing inflexible turning head wheel and the bottom wheel bearings is ineffective, increase of resistance moment, causing the hopper belt. When the detachable gas or replacement of bearings.
