Description

Technical Field

[0001] The present application belongs to the field of vertical barrel pumps, and more specifically, to a disassembly and assembly maintenance tool for a heavy rotor of a vertical barrel pump. Background Art

[0002] Vertical barrel pump is an important fluid conveying equipment widely used in the industrial field, especially in the chemical, petroleum, electric power and other industries. Its performance stability and reliability play a vital role in the entire production process. Due to the structural characteristics of the vertical barrel pump, the rotor axis (that is, the axis of the rotor main shaft) of the vertical barrel pump installed on site is in a vertical state. At this time, the entire rotor weight is pressed on the pump side coupling half section through the shaft head nut. In the prior art, when disassembling and replacing the pump side coupling half section or bearing, it is necessary to loosen the shaft head nut with a wrench before the subsequent disassembly of the pump side coupling half section and bearing can be carried out. However, for large vertical barrel pumps, they often carry heavy rotors, especially when the rotor weight reaches more than 200kg. This disassembly method has great disadvantages. At this time, the wrench torque needs to overcome the rotor weight to make the shaft head nut press against the static friction of the half-section end face of the pump side coupling. Due to the heavy weight of the rotor, this static friction is also very large. Therefore, it is necessary to apply a large torque on the wrench to loosen the shaft head nut, which makes disassembly time-consuming and laborious. In serious cases, the entire barrel pump needs to be taken out of the installation position and placed horizontally so that the static friction of the rotor acting on the shaft head nut on the half-section end of the pump side coupling disappears before the shaft head nut can be loosened to complete the replacement of other parts; with problems such as difficult operation, low work efficiency, and high safety risks, it cannot meet the requirements of modern industry for high efficiency, safety, and environmental protection. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0005] Vertical rods are arranged in parallel on the left and right sides of the rotor main shaft;

[0006] An adjusting nut, threadedly connected to the vertical rod and capable of moving along the axial direction of the vertical rod;

[0007] A crossbeam, movably mounted on the vertical pole and abutting against the adjusting nut;

[0008] Bolts connected between the beam and the rotor main shaft and capable of linking the rotor main shaft to the beam;

[0009] A toggle block is loosely sleeved on the bolt and connected to the end surface of the shaft head nut along the axial direction of the rotor main shaft (101) away from the pump side coupling half section.

[0010] Optionally, the vertical barrel pump heavy-duty rotor disassembly and assembly maintenance tool further comprises a fastening nut threadedly connected to the bolt and used for fastening the bolt to the crossbeam.

[0011] Optionally, a through hole for the bolt to pass through is provided on the toggle block, and the bolt passes through the through hole to connect the crossbeam and the rotor main shaft.

[0012] Optionally, the toggle block includes a flange and a hexagonal head and a cylindrical pin connected to opposite sides of the flange, and the toggle block is connected to the shaft head nut through the cylindrical pin;

[0013] The through hole is coaxially arranged with the hexagonal head and parallel to the cylindrical pin.

[0014] Optionally, at least two cylindrical pins are arranged opposite to each other along the radial direction of the flange.

[0015] Optionally, the crossbeam includes a U-shaped channel steel and a support block connected to the bottom of the U-shaped channel steel, and the vertical poles and the bolts respectively pass through the corresponding support blocks.

[0016] Optionally, the vertical barrel pump further comprises a motor bracket for mounting a driving motor;

[0017] The vertical rod is detachably threadedly connected to the motor bracket.

[0018] The beneficial effect of the disassembly and assembly maintenance tool for the heavy rotor of the vertical barrel pump provided by the present application is that: compared with the prior art, in the disassembly and assembly maintenance tool for the heavy rotor of the vertical barrel pump provided by the present application, the vertical rod is arranged in parallel on the left and right sides of the rotor main shaft and is threadedly connected with an adjusting nut, and the crossbeam is sleeved on the vertical rod and abuts against the adjusting nut. In this way, when the adjusting nut rotates and moves away from the rotor main shaft relative to the axial direction of the vertical rod, the crossbeam can be driven to move away from the rotor main shaft along the axial direction of the vertical rod, and because bolts are connected between the crossbeam and the rotor main shaft, the rotor main shaft can be driven by the crossbeam to rise along its own axial direction and effectively reduce the clamping force between the shaft head nut and the half section of the pump side coupling, so that the shaft head nut threadedly connected to the rotor main shaft can be more conveniently disassembled, and then other related parts can be conveniently disassembled, which can significantly simplify the maintenance difficulty of the vertical barrel pump in the present application, which is far superior to the prior art.

[0030] Please also read Figures 1 to 4 , a disassembly and assembly maintenance tool for a heavy-duty rotor of a vertical barrel pump provided in an embodiment of the present application is now described. The disassembly and assembly maintenance tool for a heavy-duty rotor of a vertical barrel pump is used to disassemble and assemble the heavy-duty rotor of a vertical barrel pump. In this embodiment, the vertical barrel pump includes a vertically arranged rotor main shaft 101 and a shaft head nut 102 threadedly connected to the rotor main shaft 101, and also includes a pump-side coupling half section 103 coaxially sleeved on the rotor main shaft 101, and the rotor main shaft 101 abuts against the end face of the pump-side coupling half section 103 through the shaft head nut 102. Specifically, the disassembly and assembly maintenance tool for the heavy-duty rotor of a vertical barrel pump in this embodiment includes a column, an adjusting nut 202, a crossbeam 203, a bolt 204 and a toggle block 206. Among them:

[0031] The vertical rod 201 is arranged in parallel on the left and right sides of the rotor main shaft 101, the adjusting nut 202 is threadedly connected to the vertical rod 201 and can move along the axial direction of the vertical rod 201, the crossbeam 203 is movably sleeved on the vertical rod 201 and abuts against the adjusting nut 202, the bolt 204 is connected between the crossbeam 203 and the rotor main shaft 101 and can make the rotor main shaft 101 linked to the crossbeam 203, and the toggle block 206 is loosely sleeved on the bolt 204 and connected to the end face of the shaft head nut 102 along the axial direction of the rotor main shaft 101 away from the pump side coupling half section 103.

[0032] According to the above structure provided in the present embodiment, in the disassembly and assembly maintenance tool for the heavy rotor of the vertical barrel pump provided in the present embodiment, the vertical rod 201 is arranged in parallel on the left and right sides of the rotor main shaft 101 and is threadedly connected with the adjusting nut 202, and the cross beam 203 is sleeved on the vertical rod 201 and abuts against the adjusting nut 202. In this way, when the adjusting nut 202 rotates and moves away from the rotor main shaft 101 axially relative to the vertical rod 201, the cross beam 203 can be driven to move away from the rotor main shaft 101 along the axial direction of the vertical rod 201. Since the bolt 204 is connected between the cross beam 203 and the rotor main shaft 101, the rotor main shaft 101 can rise along its own axial direction under the drive of the cross beam 203 and effectively reduce the clamping force between the shaft head nut 102 and the pump-side coupling half section 103. The shaft head nut 102 threadedly connected to the rotor main shaft 101 can also be more conveniently disassembled. Through the toggle block 206 connected to the shaft head nut 102, after the rotor main shaft 101 is lifted, the toggle block 206 can be conveniently rotated to loosen the shaft head nut 102, which effectively reduces the difficulty of disassembling the shaft head nut, and can significantly simplify the difficulty of disassembling and assembling the heavy rotor for the vertical barrel bag pump in this embodiment, which is far superior to the prior art.

[0033] It can be understood here that a threaded hole for threaded connection with the bolt 204 is opened at the end of the rotor main shaft 101.

[0034] In another embodiment of the present application, please refer to Figures 1 to 4 The heavy rotor disassembly and assembly maintenance tool for the vertical barrel pump also includes a fastening nut 205 threadedly connected to the bolt 204 and used to fasten the bolt 204 to the crossbeam 203. According to the above structure provided in this embodiment, since the fastening nut 205 can fasten the bolt 204 to the crossbeam 203, it can not only improve the connection stability between the crossbeam 203 and the rotor main shaft 101, but also help to improve the stability of the rotor main shaft 101 during movement.

[0035] In another embodiment of the present application, please refer to Figures 1 to 4The toggle block 206 is provided with a through hole 207 for the bolt 204 to pass through, and the bolt 204 passes through the through hole 207 to connect the cross beam 203 and the rotor main shaft 101. According to the above structure provided in this embodiment, the bolt 204 passes through the through hole 207 on the toggle block 206, which can make the toggle block 206 easily aligned with the shaft head nut 102, avoiding mechanical interference between the bolt 204 and the toggle block 206, which is conducive to further simplifying the difficulty of disassembling and assembling the heavy rotor for the vertical barrel bag pump in this embodiment.

[0036] In another embodiment of the present application, please refer to Figures 1 to 4 The toggle block 206 includes a flange 208 and a hexagonal head 209 and a cylindrical pin 210 connected to opposite sides of the flange 208. The toggle block 206 is connected to the shaft head nut 102 through the cylindrical pin 210. The through hole 207 is coaxially arranged with the hexagonal head 209 and parallel to the cylindrical pin 210. According to the above structure provided in this embodiment, the hexagonal head 209 of the toggle block 206 can be more convenient for the disassembly tool to twist the toggle block 206, which is conducive to further simplifying the difficulty of disassembling and assembling the heavy rotor for the vertical barrel bag pump in this embodiment.

[0037] In another embodiment of the present application, please refer to Figures 1 to 4 At least two cylindrical pins 210 are arranged opposite to each other along the radial direction of the flange 208. In this embodiment, preferably four cylindrical pins 210 are arranged and correspond to the spanner holes 213 on the shaft head nut 102. The cylindrical pins 210 extend into the spanner holes 213 for a set distance at least. According to the above structure provided in this embodiment, the four cylindrical pins 210 arranged opposite to each other along the radial direction of the flange 208 extend into the spanner holes 213, which can more easily drive the shaft head nut 102 to rotate, which is conducive to further simplifying the difficulty of disassembling and assembling the heavy rotor for the vertical barrel pump in this embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 4 The crossbeam 203 includes a U-shaped channel steel 211 and a support block 212 connected to the bottom of the U-shaped channel steel 211. The vertical rod 201 and the bolt 204 respectively pass through the corresponding support block 212. According to the above structure provided in this embodiment, the crossbeam 203 composed of the U-shaped channel steel 211 and the support block 212 has a higher structural strength, which is conducive to making the process of the crossbeam 203 driving the rotor main shaft 101 to move more stable.

[0039] In another embodiment of the present application, please refer to Figures 1 to 4The vertical barrel pump also includes a motor bracket 104 for installing a driving motor, and the vertical rod 201 is detachably threadedly connected to the motor bracket 104. According to the above structure provided in this embodiment, the motor bracket 104, which is a structural component of the vertical barrel pump itself, is used as a support. On the one hand, the vertical rod 201 can be easily installed to reduce the disassembly and assembly maintenance tools for the heavy rotor of the vertical barrel pump. On the other hand, after the rotor and the rotor main shaft 101 and other structures are installed, the vertical rod 201 can be easily disassembled from the motor bracket 104, which is conducive to further simplifying the difficulty of disassembly and assembly of the heavy rotor of the vertical barrel pump in this embodiment.
