Description

Technical Field

[0001] This utility model relates to the field of guide shoe technology, specifically a new type of guide shoe. Background Technology

[0002] Guide shoes are crucial components of coal mining machines. They support and guide the machine along the scraper conveyor's guide rails, enabling the machine to move in the scraper conveyor's direction. Because the contact area between the guide shoes and the guide rails is limited and the surface contact area is small, the internal parts are prone to wear over time. Therefore, the surface of the guide shoes needs to be treated to improve the wear resistance of the internal surface and extend the shoe's lifespan.

[0003] There are generally three methods for the internal structure of ski boots: welded wear-resistant plates, welded wear-resistant material layers, and surface heat treatment. The welded wear-resistant material layer solution typically presents two problems:

[0004] 1. If wear-resistant materials are welded, the materials are brittle and prone to chipping at the edges and corners, which can further affect the surrounding materials.

[0005] 2. The surface of the wear-resistant material layer needs to be processed, which results in high surface hardness, long processing time, and high processing costs;

[0006] The search revealed that the patent application with patent number CN117588211A, entitled "A guide shoe, a coal mining machine and a method for manufacturing guide shoes", is closest in principle to the existing technology. This is because the patent proposes to process grooves and set buffer layers and buffer parts to improve the welding firmness. However, this design cannot avoid the characteristics of the material surface that need to be processed, resulting in higher production costs.

[0007] Upon careful analysis, the aforementioned patent emphasizes the fusion of materials by using layered welding of multiple materials, allowing the materials to transition from softer to harder materials, with a focus on improving the robustness of wear-resistant materials.

[0008] This solution provides a new type of coal mining machine slipper, which works on a similar principle to the aforementioned patent. However, this solution uses a method of machining grooves on the surface of the slipper and then welding them in, which makes it easier to control the height of the wear-resistant layer. Furthermore, the use of a tough material around the grooves to wrap around the wear-resistant layer avoids the problem of high-hardness wear-resistant materials easily cracking under stress, thus improving the impact resistance of the slipper. The bottom buffer layer and buffer part are eliminated, making the structure simpler, reducing processing steps, and making it easier to manufacture. Utility Model Content

[0009] (I) Technical Issues

[0010] The present invention aims to at least solve the problems of numerous processing steps, high difficulty, and insufficient impact resistance in the existing technology.

[0011] (II) Technical Content

[0012] This solution provides a novel guide shoe, achieved through the following specific technical means, including:

[0013] The sliding shoe body has a groove on the contact surface between the inner wall of the sliding shoe body and the pin rail;

[0014] The wear-resistant layer consists of multiple layers, which are placed into the corresponding grooves and fixed in place. The thickness of the wear-resistant layer is no greater than the depth of the groove.

[0015] Preferred technical solution 1: It also includes edge wrapping, which is formed by welding, cladding or plug welding the wear-resistant layer around the wear-resistant layer and fixing it in the groove.

[0016] Preferred technical solution 2: The side of the edging closest to the groove is at the same height as the inner wall of the slipper body.

[0017] Preferred technical solution three: The edge banding forms a transition rounded corner between the side of the wear-resistant layer and the groove wall.

[0018] Preferred technical solution four: The skateboard body is a tough metal skateboard.

[0019] (III) Technical Effects

[0020] The above structure gives this solution the following advantages:

[0021] 1. Grooves are machined into the surface of the slipper before welding, which makes it easier to control the height of the wear-resistant layer;

[0022] 2. By optimizing the welding structure and avoiding surface processing of the wear-resistant layer, the manufacturing capability of the ski boots is greatly improved, and the durability of the wear-resistant material is also enhanced.

[0023] 3. By using a tough material around the groove to wrap around the wear-resistant layer, the problem of high-hardness wear-resistant materials being prone to cracking under stress is avoided, thus improving the impact resistance of the ski boots.

[0024] 4. The bottom buffer layer and buffer section have been eliminated, making the structure simpler and reducing the number of processing steps. Attached Figure Description

[0025] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:

[0026] Figure 1 This is a schematic diagram of the overall structure of this solution;

[0027] Figure 2This is a schematic diagram of the groove structure in this design.

[0028] The components are: 1. Slipper body, 2. Groove, 3. Wear-resistant layer. Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-2 The new type of guide shoe includes a shoe body with multiple sets of grooves on the contact surface between the inner wall of the shoe body and the pin rail. The grooves are formed during the casting of the shoe body or through subsequent cutting and processing. The bottom buffer layer and buffer part are eliminated, making the structure simpler.

[0031] The wear-resistant layer consists of multiple layers, which are placed into the corresponding grooves and fixed in place. The wear-resistant layer does not protrude from the groove. The hardness of the wear-resistant layer is greater than that of the skate body. The skate body is a tough metal skate. The relatively soft skate body uses the side walls of the groove to wrap around the relatively brittle wear-resistant material. The key point is that the guide corners on both sides are wrapped to prevent the edges of the wear-resistant layer from being broken and falling off due to impact, thus improving the impact resistance of the wear-resistant layer.

[0032] This method reduces the consumption of wear-resistant materials, reduces the amount of machining required for the ski boots, saves wear-resistant materials, lowers the production cost of the ski boots, improves production, and facilitates automated production.

[0033] The wear-resistant layer can be fixed by embedding it in a groove. This method requires an interference fit between the groove and the wear-resistant layer.

[0034] The wear-resistant layer can also be fixed in the groove by welding, cladding or plug welding to form an edge. That is, the edge is formed by welding, cladding or plug welding the wear-resistant layer around the wear-resistant layer and fixing it in the groove.

[0035] When choosing welding, cladding, or plug welding methods, welding should be stopped once the material fills the groove and is at the same height as the surrounding structure. This allows for effective control of the height of the wear-resistant layer. After welding, the surface can be used after slight grinding (such as grinding the sharp corners at the transition, removing excess spatter, and creating a rounded transition between the edge of the wear-resistant layer and the groove wall). This eliminates the need for subsequent machining processes, requiring no or only tool inspection, reducing tool wear during machining, and shortening the processing cycle.

[0036] The parts not disclosed in this utility model are all prior art, and their specific structures and working principles will not be described in detail.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
