如何防止斗式提升机料斗带打滑?
发布者:admin  点击:2131

斗式提升机料斗带打滑的处理方法:
(1)斗式提升机是利用料斗带与头轮传动轴间的摩擦力矩来进行升运物料的,叵料斗带张力不够,将导致料斗带打滑。这时,应立即停机,调节张紧装置以拉紧料斗带。若张紧装置不能使料斗带完全张紧,说明张紧装置的行程太短,应重新调节。
正确的解决方法是:解开料斗带接头,使底轮上的张紧装置调至最高位置,将料斗带由提升机机头放入,穿过头轮和底轮,并首尾连接好,使料斗带处于将张紧而未张紧的状态。然后使张紧装置完全张紧。此时张紧装置的调节螺杆尚未利用的张紧行程不应小于全行程的50%。
(2)提升机超载提升机超载时,阻力矩增大,导致料斗带打滑。此时应减小物料的喂入量,并力求喂料均匀。若减小喂入量后,仍不能改善打滑,则可能是机坐内物料堆积太多或料斗被导师物卡住,应停机检查,排除故障。
(3)头轮传动轴和料斗带内表面过于光滑头轮传动轴和料斗带内表面过于光滑,使两者间的摩擦力减小,导致料斗带打滑。这时,可在传动轴和料斗带内表面涂一层胶,以增大摩擦力。
(4)头轮和底轮轴承转动不灵头轮和底轮轴承转动不灵,阻力矩增大,引起料斗带打滑。这时可拆洗加油或更换轴承。

中译英:
(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.
