Description

Technical Field

[0001] This utility model belongs to the technical field of wear-resistant lining plates, and in particular relates to a wear-resistant lining plate for ore conveying. Background Technology

[0002] During ore mining, beneficiation, and transportation, the inner walls of conveying equipment (such as chutes and conveyor belt baffles) are subjected to severe erosion and wear from ore materials over a long period of time, resulting in a significant reduction in equipment lifespan and high maintenance costs. To address the wear problem, wear-resistant liners with flat plate structures are installed on the inner walls of chutes and conveyor belt baffles. Existing installation and fixing methods mostly use direct welding or bolt fixing. Although welding provides a strong connection, it is extremely inconvenient to replace the wear-resistant liner after it is damaged. Bolted connections pose a safety hazard because the bolt heads are exposed to the material flow and are easily worn, leading to loosening or failure of the connection. At the same time, frequent replacements also increase maintenance difficulty and costs. Utility Model Content

[0003] The purpose of this utility model is to provide a wear-resistant liner for ore conveying. Through the cooperation structure of the fixing seat and the blocking block, the wear-resistant liner can be quickly installed and disassembled. At the same time, all fastening structures are hidden inside to avoid direct material erosion, which significantly improves the connection reliability and service life and solves the problems mentioned in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a wear-resistant liner for ore conveying, comprising a steel plate substrate and a wear-resistant plate disposed on one side of the steel plate substrate; a mounting groove is provided on the back of the steel plate substrate, and a through hole is provided on the bottom side of the mounting groove; a blind hole concentric with the through hole is provided on the back of the wear-resistant plate, and a through hole is provided on the bottom side of the blind hole; the blind hole and the through hole have the same diameter; it also includes a fixing base, the fixing base comprising a ring fixed at the mounting groove, the inner wall of the ring having a through hole and a tube inserted into the blind hole. A raised ring is provided on the inner wall of the pipe body; the wear-resistant liner is installed on the inner wall of the baffles on both sides of the chute or conveyor belt; a stud is pre-installed on the inner wall of the chute or baffle, the stud passes through the raised ring and is threaded to the end of a nut; a plug is installed at the stepped hole formed by the blind hole and the through hole, and after installation, the plug and the wear-resistant plate are coplanar; the fast installation and replacement of the wear-resistant liner is achieved through the coordinated setting of the fixing seat and the plug; the pre-embedded stud and nut are hidden inside, avoiding direct erosion and wear by materials, and improving the reliability and safety of the connection.

[0006] Furthermore, the wear-resistant plate is a polyurethane plate or a ceramic plate.

[0007] Furthermore, the end of the tube is provided with a ring that abuts against the bottom side of the blind hole, and the inner wall of the ring is provided with an annular step; the periphery of the plug is provided with an annular protrusion that mates with the annular step; the outer diameter of the annular protrusion is slightly larger than the inner diameter of the ring, and the outer diameter of the annular protrusion is slightly smaller than the inner diameter of the annular step; the inner diameter of the ring is larger than the inner diameter of the through hole; through the dimensional fit between the annular protrusion, the ring, and the annular step, an interference fit locking effect is achieved. During installation, a little force is required to press the plug in, and the slight deformation of the material generates a fastening force, effectively preventing the plug from falling off during vibration, greatly enhancing the reliability of the structure.

[0008] Furthermore, the plug includes a plug body that rests against the ring body at its rear end, and a protruding post passing through the ring body is provided at the end of the plug body; the annular protrusion is provided on the outer peripheral sidewall of the protruding post; a groove is provided on the end face of the protruding post, and a rectangular hole is provided through the peripheral sidewall of the groove. A movable rod is movably disposed in the rectangular hole, and a guide slope is provided at one end of the movable rod located in the groove. A spherical structure is provided at the end of the stud. Through the cooperation of the movable rod, the guide slope and the spherical structure at the end of the stud, the plug can be expanded and locked, effectively resisting vibration and impact and preventing loosening during use.

[0009] Furthermore, the ring body has several openings, and the ring body is fixed to the mounting groove by welding, bolting or riveting; the fixing seat is integrally cast from metal material; this ensures the overall strength and structural stability of the fixing seat, enabling it to withstand the impact force of ore materials and the pre-tightening force provided by fasteners, making it less prone to deformation or damage, and extending its service life.

[0010] This utility model has the following beneficial effects:

[0011] This invention achieves rapid installation and disassembly of wear-resistant liners through the cooperative structure of the fixing seat and the blocking block, while hiding all fastening structures inside to prevent direct material erosion, thus significantly improving connection reliability and service life.

Detailed Implementation

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Please see Figure 1-4As shown, this utility model is a wear-resistant liner for ore conveying. The wear-resistant liner is installed on the inner wall of the chute 3 or the side baffles of the conveyor belt. The wear-resistant liner is composed of a steel plate substrate 2 and a wear-resistant plate 1. The wear-resistant plate 1 is disposed on one side of the steel plate substrate 2. The back of the steel plate substrate 2 is provided with an installation groove 20, and the bottom side of the installation groove 20 is provided with a through hole 21. The back of the wear-resistant plate 1 is provided with a blind hole 12 that is concentric with the through hole 21. The bottom side of the blind hole 12 is provided with a through hole 11. It also includes a fixing seat 5. The fixing seat 5 includes a ring 50 fixed at the installation groove 20. The inner wall of the ring 50 is provided with a tube 52 that passes through the through hole 21 and is inserted into the blind hole 12. The diameters of the blind hole 12 and the through hole 21 are the same, and the outer diameter is slightly larger than the diameter of the through hole 21. Thus, during installation, the fixing seat 5 is installed into the blind hole 12 and the through hole 21 by tapping. A protruding ring 53 is provided on the inner wall of the tube 52.

[0023] Before installation, the fixing seat 5 is permanently fixed in the mounting groove 20 on the back of the steel plate substrate 2; at the same time, studs 31 need to be pre-welded or installed on the inner wall of the chute 3 or conveyor belt baffle; the position distribution of these studs 31 must correspond one-to-one with the fixing seats 5 on the wear-resistant liner; with the steel plate substrate 2 of the wear-resistant liner facing inward, the center hole of the tube body 52 of the fixing seat 5 is aligned with the studs 31 pre-embedded on the wall of the chute 3. The studs 31 are passed through the convex ring 53 inside the tube body 52, and then the nut 32 is screwed on the end of the stud 31 and tightened. The tightening force of the nut is transmitted to the steel plate substrate 2 through the ring 50 of the fixing seat 5, and finally the entire wear-resistant liner is firmly fixed to the inner wall of the chute 3 or the side baffles of the conveyor belt. After the wear-resistant liner is fixed, a plug 4 is installed in the stepped hole formed by the blind hole 12 and the through hole 11. After installation, the plug 4 and the wear-resistant plate 1 are coplanar. The top of the plug 4 is coplanar with the wear-resistant surface of the wear-resistant plate 1. This makes the inner wall of the entire wear-resistant liner form a smooth and continuous surface, allowing the material flow to pass smoothly, avoiding friction, impact and wear caused by protruding bolt heads and other structures, and thoroughly protecting the core fasteners.

[0024] Specifically, wear-resistant plate 1 is a polyurethane plate or ceramic plate or other wear-resistant plate.

[0025] For ease of installation, such as Figure 4An annular body 54 is provided at the end of the tube body 52, which abuts against the bottom side of the blind hole 12. An annular step 55 is provided on the inner wall of the annular body 54. An annular protrusion 42 that mates with the annular step 55 is provided on the periphery of the plug block 4. The outer diameter of the annular protrusion 42 is slightly larger than the inner diameter of the annular body 54, and the outer diameter of the annular protrusion 42 is slightly smaller than the inner diameter of the annular step 55. The inner diameter of the annular body 54 is larger than the inner diameter of the through hole 11. That is, during installation, the protrusion 41 of the plug block 4 is aligned and pressed into the annular body 54 at the upper end of the fixing seat 5. Since the outer diameter of the annular protrusion 42 on the plug block 4 is slightly larger than the inner diameter of the annular body 54, a slight interference fit will be generated when it is pressed in, forming the first tightening force to prevent the plug block 4 from easily falling off.

[0026] Based on the above, in order to prevent the plug 4 from falling off due to vibration or other factors during long-term use, and to prevent the plug 4 from loosening due to long-term impact from ore, the plug 4 provided in this application includes a plug body 40 that rests against a ring 54 at its rear end after installation. The end of the plug body 40 is provided with a protrusion 41 that passes through the ring 54. An annular protrusion 42 is provided on the outer peripheral sidewall of the protrusion 41. A groove 46 is provided on the end face of the protrusion 41. A rectangular hole 43 is provided through the peripheral sidewall of the groove 46. A movable rod 44 is movably disposed in the rectangular hole 43 and is located in the groove 46. One end is provided with a guide slope 45, and the end of the stud 31 is provided with a spherical structure 33. When the plug 4 is pressed into place, the guide slope 45 at the end of the movable rod 44 inside it will contact the spherical structure 33 at the end of the tightened stud 31. As the plug 4 is pressed, the spherical structure 33 continues to squeeze the guide slope 45, forcing the movable rod 44 to open radially to both sides along the rectangular hole 43, like an internal "expansion plug". The end of the movable rod 44 abuts against the ring 54, and the movable rod 44 is used to limit the installed plug 4 to prevent the plug 4 from falling off.

[0027] To facilitate the installation of the fixing seat 5, four openings 51 are provided on the ring body 50. The ring body 50 is fixed to the mounting groove 20 by welding, bolting or riveting. The fixing seat 5 is integrally cast from metal material, which ensures the overall strength and structural stability of the fixing seat 5, enabling it to withstand the impact force of ore materials and the pre-tightening force provided by fasteners, making it less prone to deformation or damage and extending its service life.
