Description

Technical Field

[0001] The invention relates to the technical field of bucket elevators, in particular to an adaptive anti-sway device for running parts of bucket elevators. Background Art

[0002] Bucket elevator is a continuous conveying machine that uses a series of buckets evenly fixed on an endless traction component to vertically lift materials. It has the advantages of diverse conveyable items, strong adaptability to the working environment, arbitrary flow direction of items, good conveying position accuracy, controllable conveying rhythm, long conveying distance, and the ability to withstand heavy loads and impacts.

[0003] When the bucket elevator is working, the bucket scoops up the material from the storage below, and it is lifted to the top with the chain, bypasses the top wheel and flips downward. The bucket elevator pours the material into the receiving trough. The chain-driven bucket elevator is generally equipped with two parallel transmission chains, a pair of transmission sprockets on the top or bottom, and a pair of redirecting sprockets on the bottom or top. Bucket elevators are generally equipped with a casing to prevent dust from flying in the bucket elevator.

[0004] In chain transmission, the sprocket generally drives the chain to move, and the bucket follows the chain to move. However, the chain and bucket are very likely to shake during operation, affecting the operating stability, causing the material in the bucket to spill, and making the internal environment of the elevator worse. Summary of the invention

The guide rail wheels on the same elevator bucket pass through the two guide rails respectively, and the front, back, left and right four directions of the corresponding elevator bucket are limited by the cooperation of the two guide rails and the guide rail wheels. The gap adjustment mechanism drives the two guide rails to adjust the spacing under the action of the power mechanism, so that the guide rails are always in contact with the corresponding guide rail wheels.

DETAILED DESCRIPTION

[0018] See also Figure 1 , 2 The present invention discloses an adaptive anti-sway device for the running parts of a bucket elevator, comprising a gap adjustment mechanism 1, a power mechanism 2, two guide rails 3 and a plurality of guide rail wheels 4. The two guide rails 3 are vertically and parallelly arranged on the gap adjustment mechanism 1. Two guide rail wheels 4 are arranged on each elevator bucket 5. The guide rail wheels 4 on the same elevator bucket 5 pass through the two guide rails 3 respectively. The front, back, left, and right four directions of the corresponding elevator bucket 5 are limited by the cooperation of the two guide rails 3 and the guide rail wheels 4. The gap adjustment mechanism 1 drives the two guide rails 3 to adjust the spacing under the action of the power mechanism 2, so that the guide rails 3 are always in contact with the corresponding guide rail wheels 4.

[0019] The gap adjustment mechanism 1 includes a plurality of supports 11 , each of which is slidably provided with two slide seats 12 , and the two slide seats 12 on the same support 11 are respectively hingedly connected to a connecting seat 14 through a connecting arm 13 , and the connecting seat 14 is provided on a push-pull rod 15 .

[0020] Two seat bodies 16 are disposed on the support 11 , a slide bar 17 is disposed between the two seat bodies 16 , and two slide seats 12 are disposed on the slide bar 17 .

[0021] The power mechanism 2 includes a motor 21, a screw rod 22, a screw nut 23, a U-shaped frame 24 and a tension sensor 25. The driving end of the motor 21 is fixedly connected to one end of the screw rod 22. The screw rod 22 is provided with a screw nut 23 that matches it. The screw nut 23 is provided with a U-shaped frame 24. The U-shaped frame 24 is fixedly connected to one end of the push-pull rod 15 through the tension sensor 25.

[0022] The guide rail 3 includes a support plate 31 and a guide rail body 32 disposed on the support plate 31 and matched with the guide rail wheel 4 .

[0023] The guide rail body 32 is provided with a screw rod 34 passing through the support plate 31 , and the screw rod 34 is provided with a fixing nut 33 located inside the support plate 31 .

[0024] The guide rail body 32 is provided with guide portions 35 at both upper and lower ends. The cross-sectional area of ​​one end of the guide portion 35 away from the guide rail body 32 is smaller than the cross-sectional area of ​​the guide rail body 32 .

[0025] The elevator hopper 5 is provided with a connecting plate 6 fixed by bolts, and the connecting plate 6 is provided with two fixing nuts 7. The screw shaft of the guide wheel 4 is threadedly connected with the corresponding fixing nuts 7, and the screw shaft of the guide wheel 4 is provided with a locking nut 8.

[0026] Working process of the present invention: During the operation of the adaptive anti-sway device for the running parts of a bucket elevator of the present invention, when the elevator is running, the chain drives the elevator bucket 5 to move up and down. Since the guide wheel 4 is installed on the elevator bucket 5 and the guide wheel 4 can only move up and down on the guide body 222, and cannot shake left and right, front and back; therefore, the elevator bucket 5 and the chain cannot shake left and right, front and back.

[0027] When the guide rail body 32 and the guide wheel 4 are worn out after long-term use, the guide wheel 4 cannot contact the guide rail body. At this time, the tension value detected by the tension sensor 25 decreases, and then a signal is sent to the PLC controller. The PLC controller starts the motor 21 to rotate clockwise, and the motor 21 drives the screw rod 22 to rotate. The screw rod 22 drives the screw nut 23 to move upward. The screw nut 23 drives the tension sensor 25 to move upward through the U-shaped frame 24. The tension sensor 25 drives the connecting seat 14 to move upward through the push-pull rod 15 and pushes the slide 12 to move through the connecting arm 13. The slide 12 drives the guide rail 3 thereon to move, so that the guide rail body 32 contacts the corresponding guide wheel 4. When the tension value detected by the tension sensor 25 reaches the set value, a signal is sent to the PLC controller, and the PLC controller controls the motor 21 to stop working.

[0028] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
