Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization pump equipment, in particular to a desulfurization pump with a motor fine-tuning device. Background Art

[0002] The desulfurization pump is a rear-disassembly structure. When inspecting, the connecting bolts between the suspension body and the pump housing need to be removed first, and the bracket assembly needs to be dragged out backwards. When the desulfurization pump and the motor are assembled, if the coupling is directly connected, there is no disassembly space, and the coupling cannot be removed first, which will hinder the rearward movement of the desulfurization pump bracket; and the installation accuracy of the coupling is high, and the motor cannot be installed accurately by crane. Due to the large mass of the motor, manual movement is time-consuming and laborious. Utility Model Content

[0003] The utility model is aimed at the above problems and specifically designs a desulfurization pump with a motor fine-tuning device, so that the drive motor can be fine-tuned during installation and the rearward movement space of the bracket assembly during the disassembly and assembly of the desulfurization pump can be increased.

[0004] To achieve the above-mentioned purpose, the utility model provides a desulfurization pump with a motor fine-tuning device, comprising a pump body, a motor and a fine-tuning device, wherein the motor is connected to the pump body through a coupling, and is characterized in that: it also includes a fine-tuning device, which is installed on the pad and abuts against the motor; the fine-tuning device includes an adjusting positioning block and a fastener, the adjusting positioning block has multiple groups, the fastener has multiple groups, the adjusting positioning blocks are symmetrically arranged on each side end face of the pad, and the fastener is installed on the thread hole of the adjusting positioning block; the coupling is a diaphragm coupling.

[0005] By adopting the above technical solution and adding a fine-tuning device, the position of the motor on the pad can be adjusted, which solves the problem that the motor cannot be fine-tuned during the assembly of the desulfurization pump. At the same time, compared with the crane hoisting or manual handling of the motor, the fine-tuning device can more easily meet the installation accuracy requirements of the coupling, saving time and effort and increasing work efficiency; the positioning block is adjusted to provide support for the assembly of the fastener, and the fastener abuts against the motor housing and pushes the motor through its own feeding, thereby achieving fine-tuning of the motor position, which makes it easier to meet the installation accuracy requirements. In addition, the structure and working principle are simple, which is convenient for workers to understand and operate, saving the steps of crane hoisting or manual movement of the motor, and reducing the pressure of disassembly and assembly;

[0006] There are multiple groups of adjustment and positioning blocks, which are arranged on the side end faces of the pad and cooperate with the fasteners to meet the multi-directional adjustment of the motor, thereby meeting the installation requirements of the coupling. Multiple groups of fasteners fix the adjusted motor to increase assembly stability;

[0007] The diaphragm coupling is an intermediate shaft structure with a small size and easy disassembly. It can be disassembled without moving the desulfurization pump. Therefore, when disassembling the desulfurization pump, the diaphragm coupling can be removed first to increase the space for the bracket assembly to move backward when the pump body is disassembled and assembled, saving the steps of disassembling and assembling the mobile motor. At the same time, when installing again, the motor position can be slightly adjusted through fasteners to meet the installation requirements of the diaphragm coupling.

[0008] Furthermore, the fasteners are bolts and nuts, and the bolts and nuts are arranged on the same side of the adjustment and positioning block.

[0009] By adopting the above technical scheme, the bolt is threadedly connected with the nut and the adjusting positioning block in sequence, and the bolt is tightened to feed the thread along the axial direction of the thread hole. The fixed pitch limits the single feed amount of the bolt to prevent the worker's force error from affecting the fine-tuning of the motor, thereby ensuring the accurate adjustment of the motor position. The nut is used to fix the bolt. When the motor is adjusted to the appropriate position, the spare nut is used to fix the motor to prevent external factors from interfering with the motor position.

[0010] In summary, the utility model has the following advantages and beneficial technical effects:

[0011] 1. The utility model adjusts the position of the motor on the pad by arranging a fine-tuning device, thereby solving the problem that the motor cannot be fine-tuned when the desulfurization pump is disassembled and assembled; the fine-tuning device includes an adjusting positioning block and a fastener, the fastener is installed on the thread hole of the adjusting positioning block and abuts against the motor housing, and the motor housing is pushed to move in the same direction by feeding the fastener in the thread hole. Compared with hoisting the motor with a crane or manually carrying the motor, the fine-tuning device has a uniform and stable feeding, which makes it easier to meet the installation requirements of the coupling and saves time and effort.

[0012] 2. The fasteners are bolts and nuts. The bolts are threadedly connected with the nuts and the adjusting and positioning blocks in turn. The bolts are fed axially along the thread holes. The fixed pitch limits the single feed amount of the bolts to prevent uneven force from affecting the fine-tuning of the motor. The structure is simple, convenient for workers to operate, and saves the steps of disassembly and assembly of the motor. When the bolts are adjusted to meet the installation accuracy requirements of the coupling, tighten the nuts to fix the bolts, control the feed stroke, achieve the fixation of the motor, and reduce external interference.

[0013] 3. Multiple groups of adjustment and positioning blocks are set on the side end faces of the pad to facilitate the adjustment of the motor in all directions to meet the installation requirements of the coupling. They cooperate with fasteners to fix the adjusted motor position and improve the stability of various components during assembly.

[0014] 4. The coupling is a diaphragm coupling. Due to its special structure, compared with ordinary couplings, the coupling can be disassembled without moving the other parts of the desulfurization pump, thereby increasing the space for the pump body bracket to move backward, and there is no need to move the motor, saving time and effort; at the same time, when installing again, because the moving distance of each part is small, the motor can be fine-tuned through fasteners to achieve faster installation of the coupling.

[0026] The working principle of a desulfurization pump with a motor fine-tuning device of the utility model is:

[0027] 1. The equipment includes a pump body 1, a motor 3 and a fine-tuning device 5. The motor 3 is arranged on a pad 4 for adjusting the assembly height. The output shaft of the motor 3 is connected to the shaft in the pump body 1 through a coupling 2. The axes of the three coincide with each other. The fine-tuning device 5 is installed on the pad 4 and contacts the housing of the motor 3. The fine-tuning device 5 includes an adjustment positioning block 501 and a fastener 502. The adjustment positioning block 501 is welded on the side end surface of the pad 4. The adjustment positioning block 501 is provided with a thread hole, and the fastener 502 is installed on the thread hole. When the desulfurization pump is installed, the position of the motor 3 assembled on the pad 4 is adjusted by the fine-tuning device 5, so as to meet the installation requirements of the coupling 2. The adjustment positioning block 501 provides support for the installation of the fastener 502. The fastener 502 passes through the thread hole on the adjustment positioning block 501 and abuts against the housing of the motor 3. The position of the motor 3 is fine-tuned by feeding the fastener 502, which saves the steps of disassembly and assembly of the motor 3 by crane hoisting or manual movement, and meets the requirements of the overall installation accuracy.

[0028] There are 8 groups of adjusting and positioning blocks 501, which are symmetrically welded on the side end faces of the pad 4. There are 8 groups of fasteners 502, which are respectively installed on the thread holes of the adjusting and positioning blocks 501, so as to achieve multi-directional and multi-angle adjustment of the motor 3 and meet the installation accuracy requirements of the coupling 2.

[0029] The coupling 2 is a diaphragm coupling 2. Due to the intermediate shaft structure of the diaphragm coupling 2, the coupling 2 can be disassembled without moving the desulfurization pump, thereby increasing the space for the rearward movement of the bracket assembly of the pump body 1. The desulfurization pump can be disassembled and assembled without moving the pump body 1 and the motor 3, thus saving the steps of disassembly and assembly of the motor 3 by mechanical or manpower movement. At the same time, when reinstalling after disassembly, the position movement of the various components of the desulfurization pump is smaller, which saves time and effort.

[0030] 2. The fastener 502 is a bolt and a nut, which are arranged on the same side of the adjusting and positioning block 501. The screw in the bolt is threadedly connected with the nut and the adjusting and positioning block 501 in turn, and the bottom surface of the screw is against the housing of the motor 3; in the process of tightening the bolt, the thread is axially fed in the thread hole and pushes the motor 3 abutting against the bolt to move in the same direction, thereby achieving fine-tuning of the position of the motor 3; the fixed pitch limits the single feed stroke of the bolt to avoid uneven force affecting the azimuth adjustment of the motor 3, thereby achieving uniform and stable adjustment of the position of the motor 3; after the position of the motor 3 is adjusted to meet the installation accuracy requirements of the coupling 2, the nut is tightened to fix the feed stroke of the bolt, thereby achieving fixation of the position of the motor 3.

[0031] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
