Water-lubricated oil-free screw air compressor overhauling device

Abstract

A maintenance device for a water-lubricated oilless screw air compressor includes a mounting base in the center of a mounting frame. A worm gear reducer is mounted on the mounting base. A power input shaft is connected to the power input end of the worm gear reducer, and a power output shaft is connected to its power output end. A connecting flange is provided at the end of the power output shaft for connection to the water-lubricated oilless screw air compressor. By rotating the power input shaft, the power output shaft is slowly rotated by the worm gear reducer, easily adjusting the air compressor to a suitable position. The air compressor is suspended in the air, allowing operators to perform maintenance from any angle, greatly reducing the difficulty of operation. Simultaneously, it provides reliable support for the air compressor, ensuring its stability during disassembly and assembly, effectively preventing scratches and deformation of critical components due to compressor shaking or uneven stress, thus reducing the risk of damage during maintenance.

Description

Technical Field

[0001] This utility model belongs to the field of maintenance equipment technology, specifically relating to a maintenance device for a water-lubricated oilless screw air compressor. Background Technology

[0002] Water-lubricated oilless screw air compressors have gained widespread application in industrial production due to their numerous advantages, including environmental friendliness, energy efficiency, and stable operation. However, these compressors require regular maintenance and repair. Currently, there is a lack of specialized maintenance tools for water-lubricated oilless screw air compressors, often posing significant challenges for maintenance personnel when disassembling and assembling the equipment.

[0003] Because water-lubricated oilless screw air compressors have a complex structure and require extremely high precision in the fitting of internal components, even slight carelessness during disassembly and assembly can lead to damage to equipment parts. For example, critical components such as the rotor, bearings, mechanical seals, and compressor chamber can easily suffer scratches, deformation, and damage if handled improperly during disassembly and assembly, thereby affecting the performance and service life of the equipment and making it difficult to effectively guarantee the quality of maintenance.

[0004] Therefore, there is an urgent need to develop a specialized maintenance tool that can effectively solve the above problems in order to reduce equipment failure rate and improve maintenance efficiency and quality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a water-lubricated oilless screw air compressor maintenance device that is reasonably designed, simple in structure, easy to operate, and improves maintenance efficiency.

[0006] The technical solution adopted to solve the above technical problems is: a maintenance device for a water-lubricated oilless screw air compressor, wherein a mounting base is provided in the middle of the mounting frame, a worm gear reducer is provided on the mounting base, a power input shaft is connected to the power input end of the worm gear reducer, a power output shaft is connected to the power output end, and a connecting flange is provided at the end of the power output shaft for connecting to the water-lubricated oilless screw air compressor.

[0007] Preferably, the power input shaft is a Z-shaped shaft, and a handle is provided at the end of the power input shaft.

[0008] Preferably, the mounting bracket is provided with a lug plate, the power input shaft passes through the lug plate and is rotatably connected to the lug plate, and the lug plate is located in the middle of the power input shaft.

[0009] Preferably, a bearing housing is provided between the power output shaft and the mounting bracket.

[0010] Preferably, a bearing is provided between the bearing housing and the power output shaft.

[0011] Preferably, the mounting bracket is provided with a counterweight.

[0012] Preferably, a mobile gantry crane is also included.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a worm gear reducer to slowly rotate the power output shaft via the rotation of the power input shaft, easily adjusting the air compressor to a suitable position. Furthermore, the air compressor is suspended in the air, allowing operators to inspect it from any angle, significantly reducing the difficulty of maintenance. Simultaneously, this invention provides reliable support for the air compressor, ensuring its stability during assembly and disassembly. This effectively prevents scratches and deformation of critical components such as the rotor, bearings, mechanical seals, and compressor cavity caused by compressor vibration or uneven stress, minimizing the risk of damage during maintenance and contributing to extending the air compressor's service life.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0019] exist Figure 1 , 2In this embodiment, the maintenance device for a water-lubricated oilless screw air compressor has a mounting base 7 fixedly installed in the middle of the mounting frame 6. A worm gear reducer 5 is fixedly installed on the mounting base 7. The worm gear reducer 5 is a commercially available product. The power input end of the worm gear reducer 5 is connected to the power input shaft 9, and the power output end is connected to the power output shaft 4. The power input shaft 9 is a Z-shaped shaft with a handle 12 at its end. The power input shaft 9 passes through and is rotatably connected to the ear plate 10 fixed on the mounting frame 6. The ear plate 10 is located in the middle of the power input shaft 9 and provides support for the power input shaft 9. A bearing housing 3 is fixedly installed on the mounting frame 6 in the direction of the power output shaft 4. The power output shaft 4 passes through the bearing housing 3 and a bearing 11 is installed between the bearing housing 3 and the bearing housing 3. The bearing housing 3 provides support for the power output shaft 4. A connecting flange 2 is fixedly installed at the end of the power output shaft 4 for connecting to the water-lubricated oilless screw air compressor.

[0020] A counterweight 8 is fixedly installed on the lower part of the mounting bracket 6 on the opposite side of the power output shaft 4 to prevent the mounting bracket 6 from tipping over.

[0021] The water-lubricated oilless screw air compressor maintenance device in this embodiment also includes a movable gantry 1. The movable gantry 1 is a commercially available product. The movable gantry 1 is used to lift the water-lubricated oilless screw air compressor, facilitating the installation and removal of the water-lubricated oilless screw air compressor from the power output shaft 4. During installation, the movable gantry 1 lifts the water-lubricated oilless screw air compressor to a suitable height and securely installs it on the power output shaft 4.

[0022] When the operator is performing maintenance, he holds handle 12 and rotates the power input shaft 9. The power output shaft 4 rotates slowly. At this time, the water-lubricated oilless screw air compressor rotates together with the power output shaft 4. After rotating the air compressor to a suitable position, the front and rear end parts of the air compressor main shaft and the front and rear end parts of the star wheel shaft can be disassembled and maintained.
