Description

Technical Field

[0001] This utility model relates to the field of mining equipment maintenance technology, and in particular to a disassembly tool for a gyratory crusher bearing seat. Background Technology

[0002] As a core piece of equipment in mining, metallurgy, and other fields, the gyratory crusher requires maintenance or replacement of its key component, the eccentric bearing housing, after long-term operation. However, in existing technologies, the lower frame of the gyratory crusher is tightly fitted to the eccentric bearing housing, resulting in extremely limited disassembly space and making it difficult to operate effectively with conventional tools. Specifically, existing disassembly methods have the following problems:

[0003] Lack of stable force application point: Due to structural limitations, traditional tools such as jacks cannot find a reliable support position in a limited space. During the application of force, they are prone to deviation or slippage, which affects disassembly efficiency and may even damage equipment parts.

[0004] High operational difficulty: When disassembling by hand or using simple tools, it is necessary to manually adjust the direction of force, which is not only time-consuming and labor-intensive, but also poses safety hazards.

[0005] Insufficient adaptability: Traditional tooling has a fixed height and cannot adjust the force application height according to actual working conditions, resulting in poor compatibility during the disassembly process and difficulty in meeting the disassembly needs of different models of equipment.

[0006] While some disassembly fixtures exist in existing technologies, their structures are simple and not optimized for the specific working conditions of gyratory crushers. For example, some solutions use a single screw or rigid support structure, which cannot achieve height adjustment and stable force transmission, and lack anti-slip and limiting designs, easily leading to force application failure. Therefore, there is an urgent need for a dedicated disassembly fixture that can adapt to narrow spaces, provide stable support, and has height adjustment capabilities to solve the aforementioned technical pain points.

[0007] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0008] To address the aforementioned problems, the present invention aims to provide a disassembly fixture for a gyratory crusher bearing housing, which offers advantages such as providing stable support, adapting to narrow spaces, and having height adjustment capabilities.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] This application provides a disassembly fixture for a gyratory crusher bearing housing, the technical solution of which is as follows: It includes a base; a bolt, disposed at the bottom of the base, with an axially penetrating channel running through its center; a support rod, passing through the channel of the bolt, with its upper end extending beyond the top of the bolt and forming a support plate; wherein, a region for limiting a jack is formed between the support plate and the base above it; the support plate is used to position the jack and, when the jack applies force, transmits the pushing force downwards to disassemble the eccentric bearing housing of the gyratory crusher.

[0011] Furthermore, this application also proposes that the base includes an upper positioning plate and a lower positioning plate, as well as at least two double-ended screws, the two ends of which pass through the two ends of the upper positioning plate and the lower positioning plate respectively, and are fixed by nuts.

[0012] Furthermore, this application also proposes that the double-ended screw adjusts the distance between the upper and lower positioning plates by adjusting the position of the nut, thereby adapting to the force application height of the jack.

[0013] Furthermore, this application also proposes that the bolt is rotatably mounted on the lower positioning plate, and a nut is provided at the upper end of the bolt, so that rotating the nut can drive the bolt to rotate relative to the lower positioning plate.

[0014] Furthermore, this application also proposes that the support plate is constructed as a circular plate with anti-slip texture on its surface for fixing the bottom of the jack.

[0015] Furthermore, this application also proposes that the channel between the support rod and the bolt is a clearance fit, allowing the support rod to move freely along the axial direction.

[0016] As can be seen from the above, the gyratory crusher bearing housing disassembly fixture provided in this application can provide stable support in a narrow space through the cooperation of the base, bolts, support rods and support plates, and can adapt to different working conditions through the height adjustment function. It has the advantages of providing stable support, adapting to narrow spaces and having a height adjustment function. Attached Figure Description

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0024] like Figure 1As shown, this embodiment relates to a disassembly fixture for a gyratory crusher bearing housing, including a base, bolts 3, and a support rod 4. Bolts 3 are located at the bottom of the base, and an axially penetrating channel is constructed within their interior. The support rod 4 passes through the channel of bolt 3, with its upper end extending beyond the top of bolt 3 and forming a support plate 8. A region for limiting a jack is formed between the support plate 8 and the base above it. The support plate 8 is used to position the jack and, when the jack applies force, transmits downward pushing force to disassemble the eccentric bearing housing of the gyratory crusher.

[0025] The channel of bolt 3 provides a path for the support rod 4 to pass through, ensuring its vertical movement. The support rod 4 passes through the channel of bolt 3, and the support plate 8 built at its upper end forms a limiting area with the base, used to fix the jack and ensure stability during force application. The support plate 8 not only positions the jack but also transmits the upward force downward when the jack applies force, thus effectively disassembling the eccentric bearing seat. The base, as the foundation of the entire fixture, provides a stable support structure. Bolt 3 is located at the bottom of the base, and its internal channel provides a path for the support rod 4 to pass through, ensuring its vertical movement. The support rod 4 passes through the channel of bolt 3, and the support plate 8 built at its upper end forms a limiting area with the base, used to fix the jack and ensure stability during force application. The support plate 8 not only positions the jack but also transmits the upward force downward when the jack applies force, thus effectively disassembling the eccentric bearing seat. Through the synergy of these technical features, this tooling can provide a stable force application point in confined spaces, simplify the operation process, and adapt to different disassembly requirements. Compared with existing technologies, this tooling has advantages such as simple structure, convenient operation, and strong adaptability, and can effectively solve the technical problems of lack of a stable force application point, high operation difficulty, and insufficient adaptability when disassembling the eccentric bearing seat of a gyratory crusher in confined spaces.

[0026] like Figure 1As shown, the base includes an upper positioning plate 6 and a lower positioning plate 1, as well as at least two double-ended screws 5. The two ends of the double-ended screws 5 pass through the two ends of the upper positioning plate 6 and the lower positioning plate 1, respectively, and are fixed by nuts 2. The length of the double-ended screws 5 can be adjusted according to actual needs to accommodate jacks of different heights. The upper positioning plate 6 and the lower positioning plate 1 can be made of high-strength steel to ensure they do not deform during force application. The nuts 2 can have an anti-loosening design to prevent loosening during force application. Specifically, the diameter and thread specification of the double-ended screws 5 can be selected according to actual force requirements to ensure they do not break or strip during force application. The thickness of the upper positioning plate 6 and the lower positioning plate 1 can be selected according to actual force requirements to ensure they do not bend or break during force application. The nuts 2 can be hexagonal nuts or wing nuts for easy manual or tool operation. Furthermore, washers can be placed at both ends of the double-ended screws 5 to increase the contact area and reduce local stress concentration.

[0027] Furthermore, this application proposes that the double-ended screw 5 adjusts the distance between the upper positioning plate 6 and the lower positioning plate 1 by adjusting the position of the nut 2, thereby adapting to the force application height of the jack. Specifically, the two ends of the double-ended screw 5 pass through the two ends of the upper positioning plate 6 and the lower positioning plate 1 respectively, and are fixed by the nut 2. By rotating the nut 2, the distance between the upper positioning plate 6 and the lower positioning plate 1 can be changed, thereby adapting to the force application height requirements of the jack under different working conditions. For example, the nut 2 can be a standard hexagonal nut or a wing nut, which is convenient for manual adjustment; in addition, the thread of the nut 2 can be tightly matched with the thread of the double-ended screw 5 to ensure that the adjusted distance is stable and reliable. In this way, by adjusting the position of the nut 2, this technical solution can flexibly adjust the distance between the upper positioning plate 6 and the lower positioning plate 1, thereby solving the problem that the traditional tooling has a fixed height and cannot adapt to different force application heights. Compared with the prior art, this solution not only improves the adaptability of disassembly tooling, but also ensures the stability and accuracy of the jack when applying force. By precisely controlling the spacing, the top force can be effectively transmitted, reducing operational difficulty and improving disassembly efficiency.

[0028] Furthermore, bolt 3 is rotatably mounted on the lower positioning plate 1, and a nut 7 is provided at the upper end of bolt 3. Rotating the nut 7 can drive bolt 3 to rotate relative to the lower positioning plate 1. Specifically, bolt 3 is rotatably mounted on the lower positioning plate 1, allowing it to rotate relative to it. The nut 7 at the upper end of bolt 3 drives bolt 3 to rotate, thus realizing the rotation function of bolt 3 on the lower positioning plate 1. This design solves the technical problem of bolt 3 being unable to rotate on the lower positioning plate 1, allowing for more flexible adjustment of bolt 3's position during use and improving disassembly efficiency. Specifically, the rotation of bolt 3 can be achieved through bearings or sliding fits, and the rotation of nut 7 can be driven manually or with power tools. As a preferred embodiment, nut 7 can be a hexagonal nut, facilitating rotation with a wrench. Therefore, the rotation function of bolt 3 allows the tooling to more easily adjust its position, adapting to different disassembly needs and improving operational convenience and efficiency. Thus, this technical solution, through a simple structural design, effectively solves the problem of bolt 3 being unable to rotate on the lower positioning plate 1, improving the practicality and flexibility of the tooling.

[0029] Furthermore, this application proposes that the support plate 8 be constructed as a circular plate with anti-slip textures on its surface for securing the bottom of the jack. Specifically, the circular shape design allows the jack to distribute force evenly during application, avoiding displacement or slippage caused by localized stress concentration. The anti-slip textures further enhance the friction between the support plate 8 and the jack, ensuring the jack is stably fixed to the support plate 8 during application, preventing slippage. As a preferred embodiment, the anti-slip textures can take various forms such as cross-grid, wavy, or serrated shapes to adapt to the bottom structure of different jack models. In this regard, the circular design of the support plate 8 not only provides a uniform force distribution but also simplifies the jack positioning process, making operation more convenient. The presence of the anti-slip textures effectively solves the technical problem of jack displacement or slippage during application, thereby improving disassembly efficiency and safety. Compared with the prior art, the technical solution of this application achieves stable fixation of the jack through simple structural improvement, avoiding equipment damage or operational risks caused by unstable force application, and has significant practicality and innovation.

[0030] Furthermore, the channel between the support rod 4 and the bolt 3 is a clearance fit, allowing the support rod 4 to move freely axially. Specifically, the clearance fit design allows the support rod 4 to move freely axially within the channel of the bolt 3, avoiding jamming or movement difficulties caused by excessive tightness. As a preferred embodiment, the clearance fit size can be adjusted according to actual needs to ensure smooth movement of the support rod 4 during force application, while avoiding wobbling or inaccurate positioning due to excessive clearance. In addition, the surface of the support rod 4 can be specially treated, such as by coating with a lubricating coating or using a low-friction material, to further reduce movement resistance and improve operational flexibility and stability. Thus, this technical solution effectively solves the problem of inflexible fit between the support rod 4 and the bolt 3 channel through the clearance fit design, allowing the support rod 4 to be flexibly adjusted in position according to actual needs. Compared with the prior art, this solution not only improves the adaptability and operational efficiency of the tooling but also ensures smooth disassembly, avoiding force application failure or equipment damage caused by excessive tightness. Through this design, the support rod 4 can move freely during force application, further enhancing the practicality and reliability of the tooling.
