Description
Technical Field
[0001] This utility model belongs to the field of vanadium-titanium magnetite crushing technology, specifically relating to a wear-resistant liner for a crusher. Background Technology
[0002] Vanadium-titanium magnetite is a composite mineral resource containing multiple valuable elements such as iron, vanadium, and titanium. It plays an irreplaceable role in the steel industry and high-end materials fields (such as aerospace and new energy). Crusher is required in the operation of vanadium-titanium magnetite. When the crusher is in use, because the rocks inside are relatively hard, liners are usually installed on the inner wall to achieve a protective function.
[0003] In the current crusher, wear-resistant liners are usually installed and fixed to the inner wall of the crusher by bolts. However, there is no special protective structure for the bolts designed for this installation method. As a result, when the vanadium-titanium magnetite ore rolls and impacts in the crushing chamber during long-term operation of the crusher, it is easy to directly impact the bolt head. After long-term accumulation of this continuous impact, it may cause wear on the bolt end, or even cause the bolt to loosen, which will have an adverse effect on the subsequent stable and long-term use of the crusher. Utility Model Content
[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wear-resistant liner for a crusher. This addresses the problem that existing technologies typically use bolt connections for installation and fixation to the inner wall of the crusher. However, there is no dedicated protective structure for the bolts in commercially available designs for this installation method. This leads to the bolt heads being directly impacted by the rolling and colliding vanadium-titanium magnetite ore within the crushing chamber during prolonged crushing operation. This continuous impact, accumulated over time, can cause wear on the bolt ends and even loosen the bolts entirely, negatively impacting the subsequent stability and long-term use of the crusher.
[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a wear-resistant liner for a crusher, including an inner wall of the crusher. A pre-guiding mechanism is provided on the inner side of the inner wall of the crusher, and a liner body is installed on the inner side of the pre-guiding mechanism. Crushing teeth are provided on the inner side of the liner body, and a protective installation mechanism is installed on the inner side of the liner body. The protective installation mechanism includes an installation component, which is located on the inner side of the liner body and the inner wall of the crusher. A protective component is provided on the inner side of the liner body.
[0006] Furthermore, the installation assembly includes a preset screw groove, which is located on the inner side of the inner wall of the crusher. The inner side of the liner body is provided with an alignment screw groove, and a bolt rod is screwed into the middle of the alignment screw groove.
[0007] Furthermore, the alignment threaded groove is sized to match its preset threaded groove.
[0008] Furthermore, the protective component includes two pairs of side blocks, which are respectively disposed on the inner sides of the liner body. One of the side blocks has a fixed block fixed at one end inside, and a return spring is fixed on both sides of the inner side of the fixed block. The end of the return spring is connected to a connecting plate, and a protective plate is fixed below the connecting plate. Slider blocks are fixed on both sides above one end of the protective plate. The other side block has a groove in the middle, and the protective plate has preset openings on both sides of the middle.
[0009] Furthermore, the protective plate utilizes sliders, grooves, and edge blocks to form a guide connection.
[0010] Furthermore, the pre-loading mechanism includes a loading groove, which is located on the inner side of the inner wall of the crusher. Guide blocks are fixed on both sides of the middle part of the loading groove, clamping blocks are fixed on both sides of the liner body, and pre-loading grooves are opened on both sides of the rear end of the liner body.
[0011] Furthermore, the liner body is connected to the inner wall of the crusher by a pre-guided assembly mechanism.
[0012] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model allows personnel to pull the protective plate. Under the limiting cooperation of the slider and the slide groove at one end, the return spring connected to the other end of the protective plate is compressed, causing the protective plate to complete the displacement of the corresponding stroke. Since there are preset openings in the middle of the two sections of the protective plate, in this state, the two preset openings will move synchronously in the same direction with the protective plate, thereby exposing the preset screw groove and the alignment screw groove that were initially covered. At this time, the personnel can screw the bolt rods into these two screw grooves one by one until the liner body and the inner wall of the crusher are stably assembled. After the assembly is completed, the personnel slowly release the protective plate. At this time, the protective plate will return to its original position with the elasticity of the return spring, providing protection for the threaded part of the bolt rod. If disassembly is required later, the above steps can be followed.
[0013] This invention allows personnel to pre-align and fit the clamping block with the pre-installation slot and the guide slot with the guide block, guiding the liner body to the corresponding inner part of the crusher's inner wall. This operation can achieve the effect of preliminary positioning and auxiliary calibration of the liner body. Attached Figure Description

Detailed Implementation
[0017] 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.
[0018] This specific embodiment is a wear-resistant liner for a crusher, and its structural schematic diagram is shown below. Figures 1 to 4As shown, the crusher includes an inner wall 1, a pre-guiding mechanism 2 is provided on the inner side of the inner wall 1, and a liner body 3 is installed on the inner side of the pre-guiding mechanism 2. Crushing teeth 4 are provided on the inner side of the liner body 3, and a protective installation mechanism 5 is provided on the inner side of the liner body 3. The pre-guiding mechanism 2 includes a guide groove 21, which is opened on the inner side of the inner wall 1 of the crusher. Guide blocks 22 are fixed on both sides of the middle part of the guide groove 21, and clamping blocks 23 are fixed on both sides of the liner body 3. Pre-installation grooves 24 are opened on both sides of the rear end of the liner body 3. The liner body 3 forms a guiding assembly connection with the inner wall 1 of the crusher through the pre-guiding mechanism 2. Personnel pre-install the liner body 3 to the corresponding part on the inner side of the inner wall 1 of the crusher by aligning the clamping blocks 23 with the pre-installation grooves 24 and the guide grooves 21 with the guide blocks 22. This operation can achieve the effect of preliminary positioning and auxiliary calibration of the liner body 3.
[0019] The installation and protection mechanism 5 includes an installation component 51, which is located on the inner side of the liner body 3 and the inner wall 1 of the crusher. The installation component 51 includes a pre-set screw groove 511, which is located on the inner side of the inner wall 1 of the crusher. The inner side of the liner body 3 is provided with an alignment screw groove 512, and a bolt rod 513 is screwed into the middle of the alignment screw groove 512. The alignment screw groove 512 is sized to match the pre-set screw groove 511. The inner side of the liner body 3 is provided with a protection component 52. The protective component 52 includes two pairs of side mounting blocks 521, which are respectively disposed on both sides of the inner side of the liner body 3. One side mounting block 521 has a fixing block 522 fixedly mounted at one end inside, and a return spring 523 is fixedly mounted on both sides of the inner side of the fixing block 522. The end of the return spring 523 is connected to a connecting plate 524, and a protective plate 525 is fixedly mounted below the connecting plate 524. Slider blocks 526 are fixedly mounted on both sides above one end of the protective plate 525. The other side mounting block 521 has a groove 527 in the middle part. The protective plate 525 has preset openings 528 on both sides of its middle section. The protective plate 525 is connected by a slider 526, a groove 527, and a side mounting block 521. When a person pulls the protective plate 525, the slider 526 at one end, in conjunction with the groove 527, compresses the return spring 523 connected to the other end of the protective plate 525, causing the protective plate 525 to complete the corresponding stroke displacement. Since the two sections of the protective plate 525 have preset openings 528 in the middle, in this state, the two preset openings 528 will... As the protective plate 525 moves synchronously in the same direction, the initially covered pre-set screw groove 511 and alignment screw groove 512 are exposed. At this time, the personnel can screw the bolt rod 513 into these two screw grooves in sequence until the liner body 3 and the inner wall 1 of the crusher are stably assembled. After the assembly is completed, the personnel slowly release the protective plate 525. At this time, the protective plate 525 will return to its original position with the elasticity of the return spring 523, and the threaded part of the bolt rod 513 will be covered and protected. If disassembly is required later, the above steps can be followed.
[0020] It should be noted that the material of the liner body 3 in this article is NM500 low alloy plate. NM500 low alloy plate has strong wear resistance, corrosion resistance and certain impact resistance, and has a long service life, which can reduce equipment maintenance costs and downtime.
[0021] Working principle: Personnel pre-align the liner body 3 with the corresponding inner part of the crusher inner wall 1 by using the alignment of the clamping block 23 with the pre-installation slot 24 and the guide slot 21 with the guide block 22. This operation provides initial positioning and auxiliary calibration of the liner body 3. Then, personnel can pull the protective plate 525. Under the limiting action of the slider 526 and the slide groove 527 at one end, the return spring 523 connected to the other end of the protective plate 525 is compressed, causing the protective plate 525 to complete the corresponding stroke displacement. Because the protective plate 525 has a pre-set opening 5 in the middle of its two sections… 28. In this state, the two preset openings 528 will move synchronously in the same direction with the protective plate 525, thereby exposing the initially blocked preset screw groove 511 and the alignment screw groove 512. At this time, the personnel can screw the bolt rod 513 into these two screw grooves in sequence until the liner body 3 and the inner wall 1 of the crusher are stably assembled. After the assembly is completed, the personnel slowly loosen the protective plate 525. At this time, the protective plate 525 will return to its original position with the elasticity of the return spring 523, and the threaded part of the bolt rod 513 will be protected. If disassembly is required later, the above steps can be followed.
[0022] All technical features in this embodiment can be freely combined according to actual needs.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
