Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to an auxiliary hoisting device for the maintenance of the bucket of a mining loader. Background Technology

[0002] Mining loaders, as core equipment in underground mining, undertake the critical tasks of loading and transporting ore and rock. Their buckets come into direct contact with hard ore and rock, enduring long-term impact, wear, and loads, making them one of the fastest-wearing components. The integrity of the bucket directly affects the loader's operating efficiency. Deformation of the bucket body, wear of the bucket teeth, or loosening of the connecting structure can lead to decreased loading capacity, increased energy consumption, and even equipment failure and shutdown. Therefore, regular maintenance work such as bucket inspection, replacement of bucket teeth, and welding of wear-resistant layers is essential to ensuring continuous mine production.

[0003] The bucket is extremely heavy, so a hoisting device is needed to assist in the maintenance of the bucket on the mining loader.

[0004] For example, Chinese utility model patent application number 202420624172.5 discloses a hoisting device for mechanical equipment maintenance. By starting a motor and rotating gears, a moving rod pushes a crossbeam and an electric hoist upwards, adjusting the device's height. This achieves the device's height adjustment function. The hoisting device, capable of flexible height adjustment, can quickly and accurately position itself to the required working height according to different operational needs. It can also hoist large equipment or small components, ensuring a stable hoisting posture by adjusting the height and reducing safety risks caused by improper height. However, this device still has certain shortcomings. After hoisting is completed, it is not convenient to rotate or move the hoisted parts. If the parts need to be moved after hoisting, the entire device can only be pushed, which increases labor costs and significantly extends the operation time of each maintenance.

[0005] Therefore, we propose an auxiliary hoisting device for the maintenance of the bucket of a mining loader to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary hoisting device for the maintenance of the bucket of a mining loader, in order to solve the problem mentioned in the background art that, after hoisting, it is not convenient to rotate or move the hoisted parts. When the parts need to be moved after hoisting, the entire device can only be pushed, which increases labor costs and significantly extends the operation time of a single maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary hoisting device for the maintenance of a mining loader bucket, comprising a support plate, wherein a movable column is mounted on the upper surface of the support plate via a bearing seat, and a first gear is mounted on the movable column, and a second gear is provided on the right side of the first gear; A vertical column is installed on the upper surface of the movable column, and a connecting block is installed on the left side of the vertical column.

A support frame 8 is mounted on the upper surface of the support plate 1, and a first servo motor 9 is mounted on the upper surface of the support frame 8. The first servo motor 9 is connected to the connecting column 7 via an output shaft. The first servo motor 9 is mounted on the support frame 8, and its output shaft drives the connecting column 7 and the second gear 6 to rotate. The second gear 6 meshes with the first gear 5, driving the movable column 4 and the vertical column 10 to rotate as a whole, realizing the horizontal rotation adjustment of the hoisted bucket. The maintenance position can be changed without moving the equipment.

[0025] A vertical column 10 is mounted on the upper surface of the movable column 4, and a connecting block 11 is mounted on the left side of the vertical column 10. A right-angle frame 12 is hinged to the top of the vertical column 10. A first hydraulic rod 13 is mounted on the connecting block 11.

The second gear 6 meshes with the first gear 5, driving the movable column 4 and the vertical column 10 to rotate, and adjusting the hoisting direction to directly above the bucket.

[0029] The first hydraulic rod 13 is operated to extend and retract. Its lower end is hinged to the connecting block 11 and its upper end is hinged to the right-angle frame 12. This causes the right-angle frame 12 to rotate around the hinge point at the top of the vertical column 10, adjusting the pitch angle of the hoisting mechanism so that the limit frame 25 is aligned with the bucket hoisting point.

[0030] Start the second servo motor 23 to drive the left and right lead screws 20 in the adjusting block 19 to rotate, so that the slider 21 slides along the slide groove 22. Adjust the distance between the two limit frames 25 through the connecting chain 24 to match the bucket size. Put the limit frame 25 on the bucket lifting point, tighten the clamping bolt 26 to push the clamping block 27, and clamp the bucket with the anti-slip pad on the inner wall of the limit frame 25 to prevent it from slipping.

[0031] The second hydraulic rod 17 extends and retracts, connecting the vertical block 15 on its right and the movable bar 16 on its left. The movable bar 16 is driven to slide left and right along the fixed frame 14, causing the adjusting block 19 and the bucket to move horizontally. The first hydraulic rod 13 is operated again to raise the bucket to a suitable height. If the maintenance angle needs to be adjusted, the first servo motor 9 can drive the entire structure to rotate, and multi-directional adjustment can be achieved without moving the equipment.

[0032] After maintenance, reverse the operation of each component, loosen the clamping bolt 26, remove the bucket, and reset the equipment to prepare for the next use, thus completing a series of tasks.
