Description

Technical Field

[0001] This utility model relates to the technical field of crusher eccentric shafts, and in particular to a crusher eccentric shaft that can be easily replaced. Background Technology

[0002] In the field of crusher operation and maintenance, the eccentric shaft, as the core transmission component of the crusher, directly affects the crushing efficiency, operational stability and service life of the crusher.

[0003] However, traditional eccentric shafts for crushers present several pain points in practical applications: On the one hand, during the disassembly and replacement of eccentric shafts, the lack of specialized suspension structures means that on-site maintenance personnel often have to spend a lot of time and effort manually fixing and moving the eccentric shaft body. This is especially true for eccentric shafts of large crushers, where their weight and size make manual operation extremely difficult, increasing disassembly difficulty and labor intensity, and also increasing the risk of safety accidents due to improper operation, seriously affecting equipment maintenance efficiency and production progress. On the other hand, traditional eccentric shafts are usually designed with a fixed length, which cannot be flexibly adjusted according to different crushing conditions, material characteristics, and equipment installation space. This makes it difficult for the eccentric shaft to perform optimally when facing complex and ever-changing crushing needs, and may even affect the overall operation of the crusher due to length mismatch, reducing the adaptability and versatility of the equipment.

[0004] Therefore, we designed a replaceable eccentric shaft for crushers to meet the needs of practical applications. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a readily replaceable eccentric shaft for a crusher.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a replaceable eccentric shaft for a crusher, including an eccentric shaft body, a suspension mechanism on the eccentric shaft body, an extension mechanism at the end of the eccentric shaft body, a bearing on the suspension mechanism, the bearing being rotatably connected to the surface of the eccentric shaft body, a receiving ring being fixedly installed on the surface of the bearing, and an insertion hole being provided on the receiving ring.

[0008] The extension mechanism includes a cavity, which is located at the end of the eccentric shaft body. A receiving plate is fixedly installed on the inner wall of the cavity. A rotating rod is rotatably connected to the receiving plate. The rotating rod is threaded and an extension rod is threadedly connected to the rotating rod. The extension rod slides on the inner wall of the cavity.

[0009] In detail, there are two bearings, and both bearings are vertically arranged.

[0010] In detail, there are two receiving rings, both of which are circular in shape and are vertically arranged.

[0011] In detail, the through hole is a cylindrical through hole, and the through hole is set horizontally.

[0012] In detail, the cavity is cylindrical, there are two cavities, the receiving plate is circular, the receiving plate is vertically arranged, and the rotating rod is horizontally arranged.

[0013] In detail, a motor is fixedly installed on the inner wall of the cavity. The motor is horizontally positioned, and the end of the motor shaft is fixedly connected to one end of the rotating rod.

[0014] In detail, a limiting rod is fixedly installed on the receiving plate, the limiting rod is horizontally set, and the extension rod slides on the limiting rod.

[0015] Core function: When it is necessary to adjust the length of the eccentric shaft body, start the motor. The motor drives the rotating rod to rotate. When the rotating rod rotates, due to the thread on its surface, it will drive the extension rod to slide linearly along the surface of the limit rod until the extension rod moves out of the cavity to a suitable length. Through the above settings, it is easy to adjust the length of the eccentric shaft body and facilitate the use of the eccentric shaft body.

[0016] When the eccentric shaft body needs to be disassembled, after the surface parts are removed, the lifting rope is passed through the insertion hole, and then the eccentric shaft body is lifted out by a crane. The insertion hole facilitates the hoisting of the eccentric shaft body and makes it easier to disassemble and replace.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. The suspension mechanism facilitates the hanging of the suspension rope and makes it easier to disassemble and replace the eccentric shaft body.

[0019] 2. With the extension mechanism, the length of the eccentric shaft body can be easily adjusted according to the usage, which is beneficial to the use of the eccentric shaft body. Attached Figure Description

[0025] 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.

[0026] Reference Figures 1-4 A replaceable eccentric shaft for a crusher includes an eccentric shaft body 1, which is the eccentric shaft of the crusher. A suspension mechanism 3 is provided on the eccentric shaft body 1 to facilitate the suspension of the lifting rope and to facilitate the disassembly and replacement of the eccentric shaft body 1. An extension mechanism 2 is provided at the end of the eccentric shaft body 1 to facilitate the adjustment of the length of the eccentric shaft body 1 according to the usage, which is beneficial to the use of the eccentric shaft body 1. The suspension mechanism 3 includes a bearing 32, which is rotatably connected to the surface of the eccentric shaft body 1. The bearing 32 is used for the installation of a receiving ring 31. The receiving ring 31 is fixedly installed on the surface of the bearing 32 and is used to receive the opening of the insertion hole 33. The insertion hole 33 is provided on the receiving ring 31 to receive the insertion of the lifting rope, thereby facilitating the lifting of the eccentric shaft body 1 and facilitating the disassembly and replacement of the eccentric shaft body 1.

[0027] The extension mechanism 2 includes a cavity 22. By providing the extension mechanism 2, the length of the eccentric shaft body 1 can be easily adjusted according to the usage, which is beneficial to the use of the eccentric shaft body 1. The cavity 22 is opened at the end of the eccentric shaft body 1. The cavity 22 is provided for the installation of the receiving plate 23. The receiving plate 23 is fixedly installed on the inner wall of the cavity 22. The receiving plate 23 is provided for the installation of the rotating rod 26. The rotating rod 26 is rotatably connected to the receiving plate 23. The rotating rod 26 is provided with threads. By providing the rotating rod 26 with threads, it is easy to drive the extension rod 21 to slide linearly along the surface of the limiting rod 25. The extension rod 21 is threadedly connected to the rotating rod 26. The extension rod 21 slides on the inner wall of the cavity 22. The extension rod 21 is provided to extend the length of the eccentric shaft body 1.

[0028] It should be further noted that there are two bearings 32. The bearings 32 are used for the installation of the receiving ring 31, and both bearings 32 are set vertically.

[0029] It should be further noted that there are two receiving rings 31, both of which are circular in shape and are vertically arranged. The receiving rings 31 are used to receive the opening of the through hole 33.

[0030] It should be further explained that the through hole 33 is a cylindrical through hole, and the through hole 33 is set horizontally. The through hole 33 is set to receive the through hole of the lifting rope, so as to facilitate the lifting of the eccentric shaft body 1 and facilitate the disassembly and replacement of the eccentric shaft body 1.

[0031] It should be further explained that the cavity 22 is cylindrical in shape, and there are two cavities 22. The cavity 22 is set for the installation of the receiving plate 23. The receiving plate 23 is circular in shape and is set vertically. The receiving plate 23 is set for the installation of the rotating rod 26. The rotating rod 26 is set horizontally. By setting the rotating rod 26 with threads, it is easy to drive the extension rod 21 to slide linearly along the surface of the limiting rod 25.

[0032] It should be further noted that a motor 24 is fixedly installed on the inner wall of the cavity 22. The motor 24 is horizontally positioned, and the shaft end of the motor 24 is fixedly connected to one end of the rotating rod 26. The motor 24 has forward and reverse rotation functions. The motor 24 is positioned to drive the rotating rod 26 to rotate.

[0033] It should be further explained that a limiting rod 25 is fixedly installed on the receiving plate 23. The limiting rod 25 is set horizontally, and the extension rod 21 slides on the limiting rod 25. The setting of the limiting rod 25 serves to limit the movement of the extension rod 21 when it moves.

[0034] Working method: When it is necessary to adjust the length of the eccentric shaft body 1, start the motor 24. The motor 24 drives the rotating rod 26 to rotate. When the rotating rod 26 rotates, due to the thread on its surface, it will drive the extension rod 21 to slide linearly along the surface of the limit rod 25 until the extension rod 21 moves out of the cavity 22 to a suitable length. Through the above settings, it is convenient to adjust the length of the eccentric shaft body 1 and facilitate the use of the eccentric shaft body 1.

[0035] When the eccentric shaft body 1 needs to be disassembled, after the surface parts are disassembled, the hoisting rope is passed through the insertion hole 33, and then the eccentric shaft body 1 is lifted out by a crane. The insertion hole 33 facilitates the hoisting of the eccentric shaft body 1 and makes it easier to disassemble and replace the eccentric shaft body 1.
