Description

TECHNICAL FIELD

[0001] The utility model relates to material conveying equipment field, concretely relates to a belt conveyor unpowered automatic deviation rectifying device. BACKGROUND

[0002] The belt conveyor is widely applied in the iron and steel industry as a bulk material conveying equipment capable of high efficiency and continuous operation. Its working principle is as follows: the head transmission drum exerts friction force on the rubber belt to drive the belt to rotate stably; the belt support roller installed between the belt head and tail can lift the belt to effectively reduce the friction resistance during operation; the belt has dual functions of traction and load bearing. However, the belt often deviates during the material conveying process. This is mainly caused by factors such as material flow impact, resistance change caused by partial support roller failure, and belt butt joint deviation. For the belt deviation problem, the existing technology generally uses adjustable deviation supports for deviation rectification.

[0003] The deviation support can swing forward and backward around the central axis of the belt running direction. Its special feature is that it is not fixedly perpendicular to the belt running direction, but can be flexibly adjusted to achieve the state of one end in front and the other end behind (along the belt running direction). When the belt deviates, the deviation support on the deviated side of the belt needs to be manually pushed towards the belt running direction and fixed to correct the belt deviation.

[0004] However, since the conveying distance of the belt conveyor is usually long and is mostly arranged overhead, when the belt deviates, not only the deviation support on the deviated side needs to be manually pushed forward, but also multiple supports often need to be adjusted at the same time, which greatly increases the labor intensity of manual deviation rectification. Moreover, due to the lack of timely adjustment, the belt is prone to severe deviation, which may cause equipment failure and affect normal production. At present, a common solution is to use electric or hydraulic drive to automatically adjust the deviation support. However, this method has the problem of high one-time investment cost.
