Description

Lifting device for disassembling bearing components Technical Field

[0001] This utility model relates to the field of disassembly technology for bearing components of vertical pipeline pumps, and particularly to a lifting device for disassembling bearing components. Background Technology

[0002] To date, there are no specialized tools for disassembling and installing bearing components in vertical pipeline pumps. Large equipment, such as cranes and forklifts, is used to achieve this. This method requires a large operating space, sophisticated equipment, and is costly, and it cannot disassemble the bearing components without removing the motor.

[0003] In view of the problems existing in the prior art, it is necessary to study and design a new type of lifting device for disassembling bearing components, so as to overcome the problems existing in the prior art. Summary of the Invention

[0004] To address the technical problems of existing dismantling equipment, such as the large operating space required, high equipment requirements, and high cost, and the inability to disassemble bearing components independently without removing the motor, this invention provides a lifting device for disassembling bearing components. This utility model mainly uses components such as a wire rope tensioner, double-arm slings, pulleys, a trolley, chain hooks, eye bolts, and a bracket to achieve the goal of lifting and moving the bearing component out of the operating space manually without removing the motor. It also allows for the reverse operation to install the bearing component. This efficient lifting method facilitates on-site maintenance and spare parts replacement.

[0005] The technical means adopted in this utility model are as follows:

[0006] A lifting device for disassembling bearing components includes: a trolley, a chain hook, eye bolt A, eye bolt B, a bracket, a fastening assembly, and a lifting wheel lock structure;

[0007] Furthermore, the bracket is secured to the underside of the top plate of the motor frame using fastening components;

[0008] Furthermore, the trolley is mounted on the bracket and can slide along the length of the bracket;

[0009] Furthermore, the trolley is equipped with chain hooks at the bottom;

[0010] Furthermore, eye bolt A is fitted onto the pump cover;

[0011] Furthermore, eye bolt B is assembled onto the motor frame;

[0012] Furthermore, the lifting wheel lock structure is installed between the pre-lifting eye screw A and the lifting eye screw B on the motor bracket to lift the bearing component.

[0013] Furthermore, the bracket is an I-beam-like structure, with one end fixed to the bottom of the motor frame top plate by fastening components, and the other end extending out of the motor frame.

[0014] Furthermore, the fastener consists of a stud, a hexagonal nut, and a washer.

[0015] Furthermore, two pulleys are installed on the inner side of the top of the trolley, and the pulleys rest on the horizontal platforms on both sides of the lower part of the support, allowing it to move on the horizontal platforms.

[0016] Furthermore, there are three eye bolts A, two of which are installed on the upper two sides of the pump cover, and one is installed in the middle of the side of the pump cover.

[0017] Furthermore, there are three lifting eye bolts B, two of which are installed on both sides below the top plate of the motor frame, and one is installed on the side of the bottom plate of the motor frame, which is set in the opposite direction to the lifting bolts A installed on the middle of the outer side of the lower end of the pump cover.

[0018] Furthermore, the lifting wheel lock structure includes: a wire rope tensioner, pulleys, and double-arm slings;

[0019] Furthermore, there are two pulleys, which are respectively mounted on the eye bolts B on both sides below the top plate of the motor frame;

[0020] Furthermore, the wire rope tensioner is mounted on the eye bolt B on the side of the motor frame base plate;

[0021] Furthermore, after the double-arm slings pass through the wire rope tensioner, both ends are respectively wrapped around pulleys and connected to the two eye bolts A mounted on the lower end of the pump cover.

[0022] The disassembly and assembly process of this utility model is as follows:

[0023] Step 1: Disconnect the coupling: Remove the extended section of the coupling and disconnect the pump and motor couplings.

[0024] The second step is to tighten the wire rope tensioner, which will cause the bearing component to begin to lift. After the bearing component separates from the pump body, it will tend to tilt. This will be done by manual intervention to keep the bearing component balanced.

[0025] Step 3: Continue lifting and tilting the rotating assembly until the eye bolts on the pump cover can be connected to the chain hook.

[0026] Step 4: Disconnect the wire rope and push the trolley to move the bearing components to the far end of the bracket.

[0027] Note: Once disassembly is complete, maintenance and replacement of spare parts can begin. The reassembly process after maintenance and replacement is the reverse of the disassembly process.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] The lifting device for disassembling bearing components provided by this utility model does not require large equipment, so it requires little space, has low equipment requirements, low cost, and does not require disassembling the motor.

[0030] In summary, the technical solution of this utility model solves the problems in the prior art, such as the large operating space required for disassembling equipment, high equipment requirements, high cost, and the inability to disassemble bearing components individually without disassembling the motor.
