Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, in particular to a device for dynamically testing the elongation of a transmission component of a bucket elevator. Background Art

[0002] Bucket elevator is a continuous conveying machine. The bottom of the transmission component of the bucket elevator is connected through the elevator tail wheel. The elevator tail wheel is fixedly installed on a transmission shaft. The left and right ends of the transmission shaft are rotatably installed on the bearing seats. The left and right bearing seats are fixedly installed on the left and right tail slides respectively. The left and right tail slides are slidably set on the left and right sides of the tail shell of the elevator. Its transmission components have two structural forms: chain and belt. A series of hoppers fixed to the transmission components are used to transport bulk materials upward in a vertical or nearly vertical direction.

[0003] At present, there is no monitoring device for the elongation of the transmission parts of the bucket elevator. When the elongation of the transmission parts of the bucket elevator is too large, it will cause the transmission parts of the bucket elevator to deviate or get stuck on the bottom. The horizontal height deviation of the transmission shaft installed on the tail wheel of the elevator is too large, which will cause the belt to deviate or the chain to jump teeth, making the operating current of the bucket elevator too large, causing the bucket elevator to stop or be damaged, resulting in major equipment accidents and property losses.

[0019] Refer to Figures 1 to 4 , this embodiment discloses a device for dynamically testing the elongation of the transmission components of a bucket elevator. The bottom of the transmission components of the bucket elevator is connected by transmission to the tail pulley 1 of the elevator. The tail pulley 1 of the elevator is fixedly installed on a transmission shaft 2. The left and right ends of the transmission shaft 2 are respectively rotatably installed on bearing seats 3. On the left and right sides of the tail housing 10 of the elevator, there are respectively slidably provided two tail skids 4 on the left and right. The two bearing seats 3 on the left and right are respectively fixedly installed on the two tail skids 4 on the left and right. On the left and right sides of the tail housing 10 of the elevator, there are respectively provided test components. The two groups of test components are respectively located above the two tail skids 4. Each group of test components includes a displacement sensor installed outside the tail housing 10. The displacement amount between it and the corresponding side tail skid 4 is measured by the displacement sensor. The installation positions of the displacement sensors of the two groups of test components are at the same height position.

[0020] The displacement sensor is a wire rope displacement sensor 5. The wire rope displacement sensor 5 is fixedly installed outside the tail housing 10 through a sensor fixing base 6. The sensor fixing base 6 can be connected to the tail housing 10 by means of screw connection. The wire rope 7 of the wire rope displacement sensor 5 hangs vertically downward. The pulling head 8 at the bottom end of the wire rope 7 is fixed on the tail skid 4. Among them, the pulling head 8 at the bottom end of the wire rope 7 is installed on the tail skid 4 through a pulling head fixing rod 9. A perforation is opened in the center of the pulling head 8. The pulling head 8 is fixedly installed on the tail skid 4 by passing the pulling head fixing rod 9 through the perforation of the pulling head 8 and tightening it in the threaded hole of the tail skid 4.

[0021] The device for dynamically testing the elongation of the transmission components of a bucket elevator provided in this embodiment measures the displacement amount between it and the tail skid 4 in real time through the displacement sensor provided on the tail housing 10, so as to reflect the height position of the tail pulley 1 of the elevator installed on the tail skid 4, and then monitor the elongation of the transmission components sleeved on the tail pulley 1 in real time, avoiding equipment accidents caused by excessive elongation of the transmission components resulting in scraping against the elevator housing and hoppers, and reducing potential safety hazards.
