TECHNICAL FIELD
[0001] The utility model belongs to material conveying equipment bucket elevator technical field especially relates to a bucket elevator safety adjusting device of movable plate wear prevention. BACKGROUND
[0002] As a common vertical conveying equipment, bucket elevator is widely used in mining, metallurgy, chemical industry, building materials and other industries, and is used for lifting materials from low to high. Its working principle is: after the hopper receives the material, it is lifted to the top with the conveying chain, and then it is turned down to unload after passing through the top wheel, and the empty hopper continues to receive the material after passing through the tail wheel, forming a continuous conveying cycle.
[0003] However, in the actual operation process of the bucket, especially when conveying large-diameter materials or other heavy materials, there are a series of technical problems to be solved:
[0004] Material spilling and accumulation: during the conveying process, due to the characteristics of the material, the design of the hopper or the vibration of the conveying chain, it is inevitable that some material will spill to the bottom of the bucket. These spilled materials gradually accumulate at the bottom, which interferes with the normal operation of the hopper.
[0005] Risk of hopper being lifted: when the bottom-accumulated material contains large-diameter material, when the material accumulation at the bottom is too much, the hopper cannot dig the material, and the material will lift the counterweight arm, movable plate, hopper, chain and tail wheel shaft upward. The existing bucket is provided with a hook connected with the counterweight device on the tail wheel bearing seat to help the hopper dig the bottom-accumulated material. However, in the case of large-diameter material, the counterweight device may be difficult to counteract the upward force, resulting in the lifting of the hopper, chain, tail wheel shaft, counterweight arm and movable plate.
[0006] Movable plate skew and wear: when the hopper is lifted, other components will be lifted with it, and the bearing seat will drive the movable plate to move upward passively. With the passage of time, the pin and pin hole of the chain are elongated due to wear, resulting in change of the running track of the counterweight arm. This further causes the movable plate to skew and displace, resulting in wear of the guide vertical plate.
[0007] Serious accident hazard: continuous friction and wear of the guide vertical plate eventually leads to wear of the movable plate through the guide vertical plate. Once the guide vertical plate is worn through, it may cause the movable plate to be stuck, and further cause serious accidents such as motor burning, reducer damage and chain rupture.
[0008] These accidents not only affect the normal operation of the bucket, but also may pose a serious threat to production safety.
[0009] In summary, the existing bucket elevator in conveying large diameter material or other heavy material, there is a movable plate skew lead to guide vertical plate wear and thus caused by serious accident hidden trouble and other technical problems. Therefore, there is an urgent need to effectively solve these problems to improve the operation stability and safety of bucket. Utility model content
