Description

Technical Field

[0001] This utility model belongs to the technical field of steel production equipment, specifically relating to an adjustment device for the cantilever belt deviation of a bucket wheel stacker-reclaimer. Background Technology

[0002] Bucket wheel stacker-reclaimers are key pieces of equipment in iron ore powder yards, primarily responsible for conveying ore powder. During operation, the conveyor belts of stacker-reclaimers are prone to belt misalignment due to various factors. This misalignment causes the belt edges to collide with the frame and related equipment, resulting in wear and tear, and in severe cases, belt tearing. This increases production costs and maintenance workload, significantly impacting the normal operation and production efficiency of the equipment. Current belt misalignment adjustment mainly relies on manual adjustment of idlers on-site. This method involves direct contact between personnel and equipment and materials, increasing the risk of human error and dust-related injuries to workers. It also negatively impacts continuous production. This method is not only inefficient but also poses safety hazards. Utility Model Content

[0003] This utility model provides a belt misalignment adjustment device for a stacker-reclaimer, which solves the problem that existing belt misalignment adjustment requires on-site manual adjustment of idlers by personnel, which is time-consuming, labor-intensive, and inefficient.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: It includes a control room and a cantilever frame. The cantilever frame is equipped with an upper idler roller and a lower idler roller. The belt feed is supported by the upper idler roller, and the belt return is supported by the lower idler roller. It also includes a camera and a hydraulic cylinder. The camera is aimed at the belt of the cantilever frame and transmits the monitored image to the control room. The control room is connected to the hydraulic cylinder. The lower idler roller is hinged to the cantilever frame, and the hydraulic cylinder is connected to the lower idler roller. Operators in the control room can remotely control the extension and retraction of the hydraulic cylinder's telescopic rod, causing the lower idler roller to rotate at an angle in the plane, thereby increasing the contact force between the belt and one end of the lower idler roller, forcing the belt to gradually return to the center position.

[0005] A more specific technical solution than the above-mentioned technical solution may be: the cantilever machine frame is provided with a base, the lower roller is connected to the support, and the support is hinged to the base.

[0006] Furthermore: the cylinder body of the hydraulic cylinder is hinged to the cantilever frame, and the lifting rod of the hydraulic cylinder is hinged to the support.

[0007] Furthermore, the lower idler roller is connected to the support via a support plate.

[0008] Furthermore, the support and the base are hinged together by a pin.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: By remotely monitoring the belt through a camera, after the operator observes that the belt is off-center, the operator can remotely control the hydraulic cylinder in the control room to push the lower idler roller to rotate it at an angle in the plane, thereby increasing the contact force between the belt and one end of the lower idler roller, forcing the belt to gradually return to the center position. This allows for remote adjustment of the belt misalignment without the need for the operator to go to the belt to adjust the idler roller, effectively improving the working environment of the operator, reducing the impact of adverse factors such as noise and dust on the operator, reducing the labor intensity of the operator, and increasing work efficiency.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and examples:

[0018] like Figures 1 to 5The stacker-reclaimer belt misalignment adjustment device shown includes a control room 1 and a cantilever frame 2. The cantilever frame 2 is equipped with an upper idler roller 4 and a lower idler roller 5. The upper idler roller 4 supports the belt 21 during feeding, and the lower idler roller 5 supports the belt 21 during return. It also includes a camera 3 and a hydraulic cylinder 6. The camera 3 is aimed at the belt 21 of the cantilever frame 2 and transmits the monitored image to the control room 1. The control room 1 is connected to the hydraulic cylinder 6. The lower idler roller 5 is hinged to the cantilever frame 2, and the hydraulic cylinder 6 is connected to the lower idler roller 5. The cantilever frame 2 is equipped with a base 51. The lower idler roller 5 is connected to a support 52, and the support 52 is hinged to the base 51. The cylinder body of the hydraulic cylinder 6 is hinged to the cantilever frame 2, and the lifting rod of the hydraulic cylinder 6 is hinged to the support 52. The lower idler roller 5 is connected to the support 52 via a support plate 54. The support 52 and the base 51 are hinged together by a pin 53.

[0019] During operation, when the operator in control room 1 observes that belt 21 is veering to the right, the operator remotely controls the extension rod of hydraulic cylinder 6 to push the left end of lower idler roller 5 forward. This increases the contact force between the returning belt 21 and the left end of lower idler roller 5, forcing belt 21 to gradually return to the center position. Figure 6 As shown; when belt 21 deviates to the left, the operator in control room 1 remotely controls the extension rod of hydraulic cylinder 6 to retract, pushing the left end of lower idler roller 5 backward. This increases the contact force between the returning belt 21 and the right end of lower idler roller 5, forcing belt 21 to gradually return to the center position, as shown. Figure 7 As shown.

[0020] It should be noted that the specific embodiments of this utility model have been described in detail. For those skilled in the art, all obvious changes made to it without departing from the spirit and scope of this utility model are within the protection scope of this utility model.
