Description

Technical Field

[0001] This utility model relates to the field of I-beam wheel technology, specifically to a wear-resistant component for an I-beam wheel. Background Technology

[0002] A bobbin is a tool used to wind metal wire or steel wire rope. Depending on the material and specifications of the wire or rope being wound, the bobbin's specifications and materials vary. Bobbins for winding steel wire are generally made of steel plates, but wooden bobbins can be used for winding thin steel wire and non-ferrous metal wire. The use of plastic bobbins is increasingly common.

[0003] For example, utility model patent CN205342124U discloses a wire EDM I-beam wheel for easy wire feeding, comprising a hollow cylinder and a flange at the end of the cylinder. The cylinder and flange are integrally formed; and both the cylinder and flange are 7mm thick. Furthermore, a circular arc transition structure with a radius R of 4.5mm is provided at the connection point between the flange and the cylinder, and the circular arc transition structure is coated with a high-strength wear-resistant coating with a thickness of 0.3-0.6mm. This utility model's integral forming of the cylinder and flange, and setting the thickness of both the cylinder and flange to 7mm, makes the overall structure of the I-beam wheel more stable and stronger without changing its working efficiency. However, after prolonged use, interference can still occur between the outer wall of the I-beam wheel and external workpieces, leading to wear on the outer wall and ultimately unevenness and damage. Therefore, we propose a wear-resistant component for the I-beam wheel. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a wear-resistant component for an I-beam wheel, including an I-beam wheel cylinder 1, with I-beam wheel flanges 13 fixedly installed at both the upper and lower ends of the I-beam wheel cylinder 1. Two symmetrically arranged first slots 7 are opened at both the upper and lower ends of the I-beam wheel cylinder 1, and the first slots 7 are connected to a second slot 8 opened on the I-beam wheel cylinder 1. Two sets of symmetrically arranged wear-resistant components are provided at the outer end of the I-beam wheel cylinder 1. Wear-resistant locking mechanisms 9 are provided at both the upper and lower ends of the I-beam wheel cylinder 1. The wear-resistant locking mechanisms 9 are used to lock the I-beam wheel cylinder 1 and the wear-resistant components.

Next, the two sets of wear-resistant components are brought closer to each other. When the third slot 10 on the wear-resistant sidewall 11 of the wear-resistant component is aligned with the second slot 8, the rotating handle 93 can be rotated. The rotating handle 93 drives the rotating rod 92 to rotate. The rotating rod 92 drives the moving plate 91 to move. The moving plate 91 drives the moving semi-conical column 94 to move. The moving semi-conical column 94 drives the downward conical column 95 to move downward. The downward conical column 95 drives the insertion column 97 to move downward. At this time, the spring 96 is compressed. The insertion column 97 is inserted into the first slot 7, the second slot 8 and the third slot 10. When the insertion column 97 is inserted to the bottom of the inner wall of the third slot 10, the rotation of the rotating handle 93 can be stopped.

[0025] In this embodiment, each set of wear-resistant components includes a semi-wear-resistant wheel 6, a wear-resistant arc-shaped part 12, and a wear-resistant sidewall 11. The wear-resistant arc-shaped part 12 is fixedly installed on the outer end of the semi-wear-resistant wheel 6, and the wear-resistant sidewall 11 is fixedly installed on the outer end of the wear-resistant arc-shaped part 12. The outer end of the wear-resistant sidewall 11 abuts against the inner end of the I-beam flange 13. A third slot 10 is opened on the inner side of the outer end of the wear-resistant sidewall 11. The third slot 10 is set corresponding to the second slot 8. The insertion post 97 is inserted into the second slot 8 and the third slot 10.

[0026] Specifically, wear-resistant components can be used to provide wear protection for the outer ends of the I-beam wheel cylinder 1 and the I-beam wheel flange 13.

[0027] In this embodiment, each of the two I-beam flanges 13 has a reinforcing groove 2 at one end away from each other. Each reinforcing groove 2 has multiple reinforcing ribs 5 that are distributed in a circular pattern fixedly installed on its inner wall. The inner end of the reinforcing ribs 5 is fixedly installed on the outer wall of the I-beam cylinder 1.

[0028] Specifically, the connection tightness between the I-beam wheel cylinder 1 and the I-beam wheel flange 13 can be improved by using the reinforcing groove 2 and the reinforcing rib 5.

[0029] In this embodiment, the upper and lower ends of the I-beam wheel cylinder 1 are provided with bearing grooves 3, and the bearing body 4 is inserted into the inner wall of the bearing groove 3.

[0030] Specifically, by inserting the bearing body 4 into the bearing groove 3, the stable rotation operation of the I-beam wheel cylinder 1 can be achieved.

[0031] In this embodiment, the outer end of the rotating rod 92 is provided with a threaded groove, and the rotating rod 92 passes through the moving plate 91.

[0032] Specifically, ensure that the rotating rod 92 does not interfere with the moving plate 91 during rotation.

[0033] In this embodiment, a limiting circular plate 99 is fixedly installed at the outer end of each guide post 98, and the outer diameter of the limiting circular plate 99 is larger than the outer diameter of the guide post 98.

[0034] Specifically, the maximum displacement of the moving plate 91 can be limited by the limiting circular plate 99.

[0035] In this embodiment, a rotating handle 93 is fixedly installed on the upper end of the rotating rod 92, and the end of the rotating rod 92 away from the rotating handle 93 is rotatably connected to the I-beam wheel cylinder 1 through a bearing.

[0036] Specifically, by rotating the handle 93, the rotating rod 92 can be directly operated, ensuring that the rotating rod 92 will not interfere with the I-beam cylinder 1 during rotation.

[0037] Working principle: When installing two sets of symmetrically arranged wear-resistant components, the two sets of wear-resistant components can be set on both sides of the I-beam cylinder 1. Next, the two sets of wear-resistant components are brought closer to each other. When the third slot 10 on the wear-resistant sidewall 11 of the wear-resistant component is aligned with the second slot 8, the rotating handle 93 can be rotated. The rotating handle 93 drives the rotating rod 92 to rotate. The rotating rod 92 drives the moving plate 91 to move. The moving plate 91 drives the moving semi-conical column 94 to move. The moving semi-conical column 94 drives the downward conical column 95 to move downward. The downward conical column 95 drives the insertion column 97 to move downward. At this time, the spring 96 is compressed. The insertion column 97 is inserted into the first slot 7, the second slot 8 and the third slot 10. When the insertion column 97 is inserted to the bottom of the inner wall of the third slot 10, the rotation of the rotating handle 93 can be stopped.
