Description

Technical Field

[0001] This invention relates to the field of desulfurization slurry circulation pump shaft sleeve disassembly technology, specifically a desulfurization slurry circulation pump shaft sleeve disassembly tool. Background Technology

[0002] When disassembling the bushing on the desulfurization slurry circulation pump, a wrench is needed to remove each bolt on the bushing.

[0003] However, some bushings may become stuck after the bolts are removed due to long-term operation, lack of lubrication or other reasons. In addition, desulfurization slurry circulation pumps usually operate in harsh environments, and impurities such as slurry and dust may enter the bearing housing and mix with the lubricating oil to form sludge, making the surface of the bushing too oily. This makes it difficult to remove the bushing directly from the housing of the desulfurization slurry circulation pump. Therefore, a tool that facilitates the removal of the bushing is proposed. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a tool for disassembling the shaft sleeve of a desulfurization slurry circulation pump. The main purpose is to solve the problem that after some bolts are removed, the shaft sleeve may become stuck due to prolonged operation, lack of lubrication, or other reasons. Furthermore, desulfurization slurry circulation pumps typically operate in harsh environments where slurry, dust, and other impurities may enter the bearing housing and mix with the lubricating oil to form sludge, making the shaft sleeve surface excessively oily and difficult to remove directly from the desulfurization slurry circulation pump housing.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A tool for disassembling a desulfurization slurry circulating pump shaft sleeve includes an operating plate disposed on the front side of the shaft sleeve body. The shaft sleeve body includes a bearing seat with multiple sets of mounting holes for auxiliary installation. Multiple sets of mounting cylinders are disposed on one side of the operating plate. The mounting cylinders are connected to the operating plate via connectors. Each mounting cylinder is provided with a limiting component for limiting its position after being inserted into the mounting holes. The limiting component includes multiple sets of square grooves disposed on the mounting cylinder. The multiple sets of square grooves are arranged in a circular array on the mounting cylinder. Each square groove is slidably connected with a limiting plate that matches the square groove. The mounting cylinder is provided with a driving component for driving each limiting plate.

[0009] Furthermore, the driving component includes a circular plate slidably connected inside the mounting cylinder, a connecting plate is provided between the circular plate and the limiting plate, the two ends of the connecting plate are rotatably connected to the limiting plate and the circular plate respectively, and a pushing component for pushing the circular plate is provided on the mounting cylinder.

[0010] Based on the aforementioned scheme, the pushing component includes a threaded sleeve fixed to the end of the mounting cylinder, a threaded rod threadedly engaged with the threaded sleeve, one end of the threaded rod being rotatably connected to the circular plate, and multiple sets of T-shaped rods slidably connected to the end of the mounting cylinder, one end of the T-shaped rod being fixed to the circular plate.

[0011] As a further embodiment of the present invention, a drive pin is fixed at the other end of the threaded rod, and a hexagonal groove is formed on the end face of the drive pin.

[0012] Furthermore, the connector is a connecting rope, and multiple sets of connecting ropes are provided, with both ends of the multiple sets of connecting ropes connected to the operating panel and the mounting cylinder, respectively.

[0013] Based on the aforementioned scheme, the control panel is fixed with two sets of handles for assisting traction and pulling.

[0014] As a further embodiment of the present invention, a positioning component is also included. The positioning component is detachably connected between the bushing body and the operating plate. The positioning component includes a connecting plate and two positioning brackets. The connecting plate and the two positioning brackets form a structure that inserts into the hole between the bushing body and the operating plate. Two blocking magnets are fixed to one side of each of the two positioning brackets by bolts, and the blocking magnets can be magnetically fixed to the bushing body.

[0015] Furthermore, it also includes a coating layer, which is applied to the ends of the plurality of limiting plates, and the coating layer is a metal-based anti-slip and wear-resistant coating or a modified polyurea elastomer coating.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention provides a tool for disassembling the shaft sleeve of a desulfurization slurry circulation pump, which has the following beneficial effects: When it is necessary to disassemble a shaft sleeve that is still stuck after the bolts have been removed, the tool of the present invention uses a limiting component to fix the mounting cylinder inside the mounting hole.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Refer to Figures 1-4 A tool for disassembling the shaft sleeve of a desulfurization slurry circulation pump includes an operating plate 2 disposed on the front side of the shaft sleeve body 1. The shaft sleeve body 1 includes a bearing seat 101, on which a plurality of mounting holes 102 for auxiliary installation are provided. It also includes a plurality of mounting cylinders 3 disposed on one side of the operating plate 2. The mounting cylinders 3 are connected to the operating plate 2 by a connector. The mounting cylinders 3 are provided with a limiting component for limiting the mounting cylinders 3 after they are inserted into the mounting holes 102.

[0027] When it is necessary to disassemble the bushing that is still stuck after the bolts are removed, the mounting cylinder 3 is fixed inside the mounting hole 102 by the limiting component. After the fixing is completed, the operating plate 2 is pulled by the handle 8. During the pulling process, the bushing is directly pulled by the connection of each connecting rope 4 and the fixing effect of the mounting cylinder 3 inside the bushing mounting hole 102. This method avoids the influence of the sludge formed on the bushing on the disassembly of the bushing during the disassembly process, and further facilitates the disassembly of the desulfurization slurry circulation pump bushing.

[0028] The limiting component includes multiple sets of square grooves 501 formed on the mounting cylinder 3. The multiple sets of square grooves 501 are arranged in a circular array on the mounting cylinder 3. Each square groove 501 is slidably connected to a limiting plate 502 that matches the square groove 501. The mounting cylinder 3 is provided with a driving component for driving each limiting plate 502. Through the driving component, each limiting plate 502 is pushed outward through the square groove 501 and the front end of each limiting plate 502 abuts against the inner wall of the mounting hole 102, so that the mounting cylinder 3 is fixed inside the mounting hole 102.

[0029] The driving assembly includes a circular plate 601 slidably connected inside the mounting cylinder 3. A connecting plate 602 is provided between the circular plate 601 and the limiting plate 502. The two ends of the connecting plate 602 are rotatably connected to the limiting plate 502 and the circular plate 601, respectively. The mounting cylinder 3 is provided with a pushing assembly for pushing the circular plate 601. Through the driving assembly, the circular plate 601 under force moves inside the mounting cylinder 3. During the movement of the circular plate 601, through the connecting transmission action of each connecting plate 602, each limiting plate 502 slides on each square groove 501.

[0030] The pushing assembly includes a threaded sleeve 701 fixed to the end of the mounting cylinder 3. A threaded rod 702 is threadedly engaged with the threaded sleeve 701. One end of the threaded rod 702 is rotatably connected to the circular plate 601. Multiple sets of T-shaped rods 704 are slidably connected to the end of the mounting cylinder 3. One end of the T-shaped rods 704 is fixed to the circular plate 601. The drive pin 703 is driven to rotate. During the rotation of the drive pin 703, the threaded rod 702 is driven to rotate. During the rotation of the threaded rod 702, the circular plate 601 moves inside the mounting cylinder 3 due to the mutual meshing transmission between the threaded rod 702 and the threaded sleeve 701 and the sliding guidance of the multiple T-shaped rods 704.

[0031] The other end of the threaded rod 702 is fixed with a drive pin 703, and the end face of the drive pin 703 is provided with a hexagonal groove; the hexagonal groove on the drive pin 703 makes it easy to rotate the drive pin 703 using a hexagonal wrench.

[0032] The connector is a connecting rope 4, and multiple sets of connecting ropes 4 are provided. The two ends of the multiple sets of connecting ropes 4 are respectively connected to the operating plate 2 and the mounting cylinder 3. The multiple sets of connecting ropes 4 facilitate the connection and transmission between the operating plate 2 and the mounting cylinder 3.

[0033] Two sets of handles 8 are fixed on the control panel 2 for auxiliary traction and pulling; the handles 8 facilitate the traction and pulling of the control panel 2.

[0034] The working principle of this embodiment is as follows: When it is necessary to disassemble the bushing that is still stuck after the bolt is removed, the multiple mounting cylinders 3 on the front side of the operating plate 2 are placed in the interior of each mounting hole 102 in sequence. After the mounting cylinders 3 are pushed in, the hexagonal wrench is inserted into the hexagonal groove of the drive pin 703. After insertion, the drive pin 703 is driven to rotate by the wrench. During the rotation of the drive pin 703, the threaded rod 702 is driven to rotate. During the rotation of the threaded rod 702, the circular plate 601 under force moves inside the mounting cylinder 3 through the mutual meshing transmission between the threaded rod 702 and the threaded sleeve 701 and the sliding guidance of multiple T-shaped rods 704.

[0035] During the movement of the circular plate 601, through the connecting transmission action of each connecting plate 602, each limiting plate 502 is pushed outward through the square groove 501 and the front end of each limiting plate 502 abuts against the inner wall of the mounting hole 102, so that the mounting cylinder 3 is fixed inside the mounting hole 102. After the fixing is completed, the operating plate 2 is pulled by the handle 8. During the pulling process, through the connecting action of each connecting rope 4 and the fixing action of the mounting cylinder 3 inside the bushing mounting hole 102, the bushing is directly pulled. This method avoids the influence of the sludge formed on the bushing on the disassembly of the bushing during the disassembly process, and further facilitates the disassembly of the desulfurization slurry circulation pump bushing.

[0036] Example 2: Refer to Figure 5A tool for disassembling the shaft sleeve of a desulfurization slurry circulation pump includes a positioning component 9. The positioning component 9 is detachably connected between the shaft sleeve body 1 and the operating plate 2. The positioning component 9 includes a connecting plate 902 and two positioning brackets 901. The connecting plate 902 and the two positioning brackets 901 form a structure that inserts into the hole between the shaft sleeve body 1 and the operating plate 2. Two blocking magnets 903 are fixed to one side of each of the two positioning brackets 901 by bolts, and the blocking magnets 903 can be magnetically fixed to the shaft sleeve body 1. In use, the positioning component 9 is inserted into the hole between the shaft sleeve body 1 and the operating plate 2, and then the blocking magnets 903 are magnetically attracted to the shaft sleeve body 1, thereby magnetically fixing the positioning component 9 inside the shaft sleeve body 1. This allows the operating plate 2 to be positioned by the positioning component 9 when it is pulled, and makes the pulling direction of the mounting cylinder 3 parallel to the axis of the mounting hole 102 of the shaft sleeve body 1, thereby reducing the friction generated by pulling and making it easier to pull.

[0037] Example 3: Refer to Figure 6 A tool for disassembling the shaft sleeve of a desulfurization slurry circulation pump includes a coating layer 10. The coating layer 10 is applied to the ends of multiple limiting plates 502. The coating layer 10 is a metal-based anti-slip and wear-resistant coating or a modified polyurea elastomer coating. First, a spraying technique is used to heat powder, filament, or rod to a molten or semi-molten state, and then spray it onto the substrate surface to form a metal-based anti-slip and wear-resistant coating or a modified polyurea elastomer coating. This not only improves the anti-slip performance of the limiting plates 502, but also greatly improves the wear resistance of the ends of the limiting plates 502, thereby effectively preventing the installation cylinder 3 from slipping off.

[0038] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
