Description

Technical Field

[0001] The utility model relates to the technical field of bucket-lift conveyors, and in particular to a device for monitoring the real-time operation of a bucket-lift conveyor. Background Art

[0002] Bucket elevator is a traditional name. It is a continuous conveying machine that uses a series of buckets evenly fixed on an endless traction member to lift materials vertically. It is generally divided into three types: ring chain, plate chain and belt. The tail wheel of the bucket elevator will move up and down during operation. When the sealing plate at the tail wheel moves up and down with the tail wheel shaft, the compression spring may be deformed and damaged due to the large surface contact friction, which leads to failure. After the compression spring fails, the sealing plate loosens and a gap is generated between the sealing plate and the shell, which may not only cause ash leakage problems, but also affect the positioning of the tail wheel, resulting in displacement. In addition, when the bucket elevator conveyor runs for a long time, its front end will be subjected to a large dynamic pressure, which may cause extrusion wear on the bearing.

[0003] The traditional method of detecting the displacement of the tail wheel of the bucket elevator mainly adopts manual inspection and regular inspection. This method is not only inefficient, but also difficult to ensure the accuracy and timeliness of monitoring, which affects the normal operation of the bucket elevator. Utility Model Content

[0006] Preferably, a bridge plate is installed on the support plate, an extension portion is provided on the support rod, a pressure sensor is provided on the support plate, and the pressure sensor is located below the extension portion.

[0007] Preferably, a first guide groove is provided on the side of the box body, the first guide groove is arranged vertically, and the limit switch of the displacement sensor extends into the first guide groove.

[0008] Preferably, second guide grooves for the rotating shaft to fit into are provided on both sides of the box body, and the second guide grooves are arranged vertically.

[0009] Preferably, a plurality of dustproof films are provided in the second guide groove, and the plurality of dustproof films are symmetrically arranged on both sides of the second guide groove, and the rotating shaft moves through a linear gap formed by the dustproof films; and both ends of the second guide groove are arc-shaped.

[0010] Preferably, a reinforcing rib support frame is provided on the outside of the box body, and the displacement sensor is installed on the reinforcing rib support frame.

[0011] The technical solution of the embodiments of the utility model has at least the following advantages and beneficial effects: the utility model arranges a displacement sensor located above the bearing seat. When the tail wheel causes the bearing seat to displace significantly, the bearing seat can contact the displacement sensor and push the limit switch to close, which is then processed by the data processing unit and fed back to the alarm unit for alarm prompt processing, thereby greatly improving the timeliness and accuracy of monitoring.
