Description

Technical Field

[0001] This utility model relates to the field of positioning rib production technology, specifically a wear-resistant storage rack for positioning ribs. Background Technology

[0002] Positioning ribs are an integral part of large hydroelectric generators. These ribs require precision machining. During mass production, manufacturers typically place a certain number of workpieces on a storage rack. The rack's function is to temporarily store the workpieces, awaiting processing equipment to retrieve them for processing. Each time a workpiece is removed, other workpieces slide down the rack due to their own weight, filling the empty space and facilitating repeated retrieval by the material handling mechanism, thus avoiding multiple manual loading. Existing storage racks generally use ordinary steel for support. After a period of use, these racks are prone to wear and even dents. At this point, workpieces cannot slide smoothly down the rack, and in severe cases, material flow jams can occur, affecting normal production, necessitating the replacement of the entire storage rack. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a wear-resistant storage rack for positioning ribs.

[0004] The specific solution of this utility model is as follows: a wear-resistant storage rack for positioning ribs, comprising several supports, each support having an inclined support beam at its top, bearing seats at both ends of the top of each support beam, and a support roller between the two bearing seats. The support roller is used to support the positioning ribs, and the support rollers on each support are parallel and located in the same plane; a worm gear reducer is connected to one end of the central shaft of each support roller, a handwheel is installed at the input end of the worm gear reducer, and the output end of the worm gear reducer is connected to the central shaft.

[0005] Furthermore, the outer surface of the support roller is provided with a wear-resistant coating.

[0006] Furthermore, the outer surface of the support roller is provided with a hardened layer.

[0007] Furthermore, a V-shaped support block is provided in the middle of the support beam, which is used to support the support roller.

[0008] This invention has the following advantages: by using a support roller instead of ordinary steel as the support for the workpiece, it can be rotated at a certain angle to continue use when wear occurs, thus improving its service life. Attached Figure Description

[0015] See Figure 1-5 This embodiment is a wear-resistant storage rack for positioning ribs, including several supports 1. Each support 1 has an inclined support beam at its top, and bearing seats 4 are installed at both ends of the top of each support beam. A support roller 5 is installed between two bearing seats 4. The support roller 5 is used to support the positioning ribs. The support rollers 5 on each support 1 are parallel and located in the same plane. One end of the central shaft of each support roller 5 is connected to a worm gear reducer 2. A handwheel 3 is installed at the input end of the worm gear reducer 2, and the output end of the worm gear reducer 2 is connected to the central shaft. Further, the outer surface of the support roller 5 is provided with a wear-resistant coating. Further, the outer surface of the support roller 5 is provided with a hardened layer, which is treated by a hardening process, and the thickness of the hardened layer is about 5-10mm. Further, a V-shaped support block 7 is provided in the middle of the support beam. The V-shaped support block 7 is used to support the support roller 5. The number of V-shaped support blocks 7 is determined according to the length of the support roller 5. A V-shaped support block 7 is set at intervals to prevent the support roller 5 from being completely suspended below, and to prevent the support roller 5 from bending when there are many workpieces 6. The working principle of this utility model is as follows: Workpieces 6 are neatly stacked on the support rollers 5 of the storage rack, with workpieces 6 perpendicular to the support rollers 5. When the material-retrieving mechanism retrieves material from the bottom of the storage rack, the upper workpieces 6 slide downwards, and there is sliding friction between the workpieces 6 and the support rollers 5. After long-term use, if wear is found on the support rollers 5, the handwheel 3 of the worm gear reducer 2 corresponding to the worn support rollers 5 is rotated, causing the support rollers 5 to rotate at a certain angle, so that the worn part moves away from the top, and the unworn part moves to the top to contact the workpieces 6. This achieves the replacement of the worn parts, greatly improving the service life. In this utility model, the worm inside the worm gear reducer 2 is connected to the handwheel 3, and the worm is connected to the central shaft of the support rollers 5. The lead angle of the worm is less than the equivalent friction angle, so the worm can only actively drive the worm to rotate, and the worm cannot drive the worm in the opposite direction, thus achieving a self-locking function. Therefore, in use, the support rollers 5 will not rotate due to the pressure of the workpieces 6, but must be driven to rotate by rotating the handwheel 3.
