[0029] Please see Figures 1-5 .

[0030] This application discloses a bearing replacement device in some embodiments, including two sets of arc-shaped fixing plates 1 and two sets of arc-shaped positioning blocks 2. The two sets of arc-shaped positioning blocks 2 are respectively installed inside the two sets of arc-shaped fixing plates 1. The two sets of arc-shaped fixing plates 1 abut against the left and right sides of the bearing respectively. The two sets of arc-shaped positioning blocks 2 are respectively engaged inside the arc-shaped grooves on both sides of the bearing. A positioning mechanism 7 is installed at the upper end of the two sets of arc-shaped fixing plates 1. A driving mechanism 3 for moving the two sets of arc-shaped fixing plates 1 is installed on the front of the two sets of arc-shaped fixing plates 1. An adjustment component 5 is installed on the front of the driving mechanism 3. A support mechanism 6 is placed on the lower surface of the two sets of arc-shaped fixing plates 1. A limit mechanism 4 is provided at the top of the driving mechanism 3. Specifically, by rotating the driving mechanism 3, the two sets of arc-shaped fixing plates 1 are driven to move the bearing forward inside the centrifugal pump. This allows the driving mechanism 3 and the arc-shaped fixing plates 1 to replace the bearing instead of a pry bar, thereby minimizing the risk of damage to the internal equipment of the centrifugal pump during the replacement process.

[0031] The driving mechanism 3 includes two sets of L-shaped fixing plates 301, which are respectively installed on the front side of two sets of arc-shaped fixing plates 1. Each set of L-shaped fixing plates 301 has a groove on its front side. A slider 302 is slidably connected inside the groove of the L-shaped fixing plate 301. A threaded hole is provided on the front side of the slider 302, and a lead screw 303 is threadedly connected inside the slider 302. A slot is provided on the back side of the lead screw 303, and a wedge block 304 is engaged inside the slot of the lead screw 303. Specifically, by pushing the two sets of sliders... 302 The positions of the two sets of wedge blocks 304 are adjusted and moved to the front of the centrifugal pump housing. Then, by rotating the two sets of lead screws 303, the two sets of wedge blocks 304 are driven to abut against the surface of the centrifugal pump housing. This allows the subsequent workers to move the two sets of L-shaped fixing plates 301 and the two sets of arc-shaped fixing plates 1 forward inside the centrifugal pump housing while continuously rotating the two sets of lead screws 303. This minimizes the risk of damage to the internal equipment of the centrifugal pump when the subsequent workers disassemble the moving bearing, thus improving the practicality of the device.

[0032] The positioning mechanism 7 includes two sets of fixing blocks 701, which are respectively installed on the upper surfaces of two sets of arc-shaped fixing plates 1. The adjacent sides of the two sets of fixing blocks 701 are in contact. Each set of fixing blocks 701 has a slot on its upper surface, and a positioning block 702 is rotatably connected inside the slot of the fixing block 701. Each set of fixing blocks 701 also has a positioning groove on its upper surface, located on the rotation path of the two sets of positioning blocks 702. Each set of fixing blocks 701 has a positioning slot on its front side, and a U-shaped locking block 703 is inserted into the two positioning slots of the fixing block 701. Specifically, by pushing the two sets of electric telescopic rods 502... The two sets of electric telescopic rods 502 are flipped, and one end of each set of electric telescopic rods 502 is rotated and locked into the positioning groove of the adjacent set of fixing blocks 701. Then, by pushing the U-shaped locking block 703, the U-shaped locking block 703 is locked into the two sets of positioning slots of the fixing block 701. This allows the subsequent positioning mechanism 7 to restrict the relative position between the two sets of arc-shaped fixing plates 1, thereby minimizing the possibility that the two sets of arc-shaped fixing plates 1 will disconnect during the process of replacing the bearing and cause the two sets of arc-shaped fixing plates 1 to fall off from the outer end of the bearing. Therefore, the stability of the two sets of arc-shaped fixing plates 1 during the bearing replacement process is improved.

[0033] The support mechanism 6 includes a base plate 601, which is placed on a disassembly table. An arc-shaped support plate 602 is installed on the upper surface of the base plate 601. The inner wall of the arc-shaped support plate 602 abuts against the lower surface of two sets of arc-shaped fixing plates 1. Specifically, by having the arc-shaped support plate 602 abut against the lower surface of the two sets of arc-shaped fixing plates 1, the arc-shaped support plate 602 supports the movement of the two sets of arc-shaped fixing plates 1, thereby minimizing the risk of the two sets of arc-shaped fixing plates 1 falling and impacting the internal parts of the centrifugal pump after the subsequent bearing is disassembled, which could damage the bearings inside the arc-shaped fixing plates 1 or the internal equipment of the centrifugal pump.

[0034] The adjusting assembly 5 includes two sets of fixed sleeves 501, which are respectively installed on the front of two sets of lead screws 303. An electric telescopic rod 502 is installed inside the fixed sleeve 501, and a connecting sleeve 503 is slidably connected inside the fixed sleeve 501. The output end of the electric telescopic rod 502 is installed on the side of the connecting sleeve 503 near the lead screw 303. Specifically, by pushing the two sets of connecting sleeves 503, the two sets of fixed sleeves 501 and the lead screw 303 are rotated. Then, by activating the two sets of electric telescopic rods 502, the two sets of connecting sleeves 503 are adjusted to increase the length of the adjusting assembly 5. This allows the adjusting assembly 5 to become a force-saving lever during use, thereby reducing the amount of labor required for workers to disassemble and move the bearing, thus improving the practicality of the device.

[0035] The limiting mechanism 4 includes two sets of screws 402. Positioning slots are provided on the upper surfaces of both sets of L-shaped fixing plates 301. The two sets of screws 402 are respectively installed on the upper surfaces of the two sets of sliders 302. The two sets of screws 402 are slidably connected inside the positioning slots of the two sets of L-shaped fixing plates 301. Nuts 401 are connected to the external threads of both sets of screws 402. The lower surfaces of the two sets of nuts 401 abut against the upper surfaces of the two sets of L-shaped fixing plates 301. Specifically, by rotating the two sets of nuts 401, the lower surfaces of the two sets of nuts 401 abut against the upper surfaces of the two sets of L-shaped fixing plates 301, thereby limiting the sliding position of the two sets of sliders 302 within the grooves of the two sets of L-shaped fixing plates 301. This minimizes the possibility of sliding during use, thus improving the stability of the subsequent drive mechanism 3 during operation.

[0036] Both sets of connecting sleeves 503 have a handle 9 fitted onto their outer surfaces. Specifically, by setting the handle 9 on the outer end of the connecting sleeve 503, the operator can increase the friction between the handle 9 and the outer end of the connecting sleeve 503, thereby minimizing the risk of the connecting sleeve 503 slipping out of the operator's hand during the subsequent operation of the connecting sleeve 503 to rotate the lead screw 303. This improves the stability of the operator during the subsequent operation of the adjusting component 5 to push the lead screw 303.

[0037] Both sets of lead screws 303 have magnetic blocks 8 installed inside their slots, and the two sets of wedge blocks 304 are made of iron. Specifically, by pushing the wedge blocks 304, the front of the wedge blocks 304 is attracted to one side of the magnetic block 8, so that the magnetic block 8 restricts the movement of the wedge blocks 304 inserted into the slots of the lead screws 303, thereby improving the stability of the wedge blocks 304 during use.

[0038] In this embodiment, by pushing the two sets of sliders 302, the positions of the two sets of wedge blocks 304 are adjusted and moved to the front of the centrifugal pump housing. Then, by rotating the two sets of lead screws 303, the two sets of wedge blocks 304 are driven to abut against the surface of the centrifugal pump housing. This allows the subsequent workers to continuously rotate the two sets of lead screws 303, causing the two sets of L-shaped fixing plates 301 and the two sets of arc-shaped fixing plates 1 to move forward inside the centrifugal pump housing, thereby minimizing the risk of damage to the internal equipment of the centrifugal pump when the moving bearing is disassembled. By pushing the two sets of electric telescopic rods 502... The two sets of electric telescopic rods 502 are flipped so that one end of each set of electric telescopic rods 502 is rotated and locked into the positioning groove of the adjacent set of fixing blocks 701. Then, by pushing the U-shaped locking block 703, the U-shaped locking block 703 is locked into the two sets of positioning slots of the fixing block 701. This allows the subsequent positioning mechanism 7 to restrict the relative position between the two sets of arc-shaped fixing plates 1, thereby minimizing the risk of the two sets of arc-shaped fixing plates 1 breaking off during the process of replacing the bearing and causing the two sets of arc-shaped fixing plates 1 to fall off from the outer end of the bearing.

[0039] Simultaneously, by pushing the two sets of connecting sleeves 503, the two sets of fixed sleeves 501 and lead screws 303 are rotated. Then, by activating the two sets of electric telescopic rods 502, the two sets of connecting sleeves 503 are adjusted to increase the length of the adjusting component 5. This allows the adjusting component 5 to be transformed into a force-saving lever during use, thereby reducing the amount of labor required by the workers to disassemble the moving bearing. By rotating the two sets of nuts 401, the lower surfaces of the two sets of nuts 401 are respectively pressed against the upper surfaces of the two sets of L-shaped fixed plates 301, so that the subsequent limiting mechanism 4 restricts the sliding position of the two sets of sliders 302 inside the grooves of the two sets of L-shaped fixed plates 301.

[0040] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed, and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. The scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept. For example, technical solutions formed by substituting the above features with, but not limited to, technical features disclosed in this application that have similar functions.
