Description

Technical Field

[0001] The invention discloses an aerial cleaning device for cleaning grease in a large-diameter antenna bearing, which is designed for large-diameter bearings that are difficult to disassemble outdoors and need to be cleaned quickly. Background Art

[0002] In the existing technology, grease testing and bearing cleaning are two independent steps. After the grease is sent for inspection, the test report is waited for, and then it is manually determined whether cleaning is needed. If cleaning is required, a professional cleaning company is contacted to come in for cleaning. The main disadvantages are: time-consuming and labor-intensive; the quality of cleaning inside the bearing is difficult to control; it is impossible to get timely results on the iron content of the grease inside the bearing; when it is learned that the iron content exceeds the standard and needs to be cleaned, the waiting time for the cleaning team and equipment to come in is long, the downtime is also long, and the maintenance cost is high; the disassembly process may cause bumps and wear of bearings and other parts; the labor cost is high and it is not economical. Summary of the invention

[0003] In view of the above problems of the prior art, the present invention aims to provide an aerial cleaning device for grease in a large-diameter antenna bearing.

[0004] In order to achieve the above purpose, the present invention adopts the following technical scheme: an aerial cleaning device for grease in a large-caliber antenna bearing, including a bearing end cover design and a cleaning device. The bearing end cover design includes circular holes drilled in four directions to facilitate the installation of an output pipe and an input pipe of the cleaning device; the cleaning device includes a leather tube, a flow rate controller, a motor pump, a cleaning agent storage box, a cleanliness detection device, a portable grease iron meter, a control system, wheels and a cart handle, an oil baffle and a cleaning nozzle. First, the iron content in the grease is detected by the iron meter, and the detection data is directly transmitted to the control system. The control system stores an iron content standard and automatically determines whether It is necessary to clean the grease inside the bearing in order to replace the clean grease. The cleaning agent in the storage box is sucked out by the motor pump, transported to the mounting hole of the end cover through the leather tube, and sprayed out by the nozzle for cleaning. The waste cleaning agent after cleaning will enter the other cabin of the storage box through the bottom output pipe. The cabin is installed with an oil baffle to effectively filter large pieces of grease to avoid clogging of the pipeline during secondary use. The cleanliness detection device in the storage box will detect the cleanliness of the waste cleaning agent and transmit the data to the control system. The control system will determine whether the waste cleaning agent can still be reused. If not, it will be directly discharged from the drain valve at the bottom of the box.

[0005] Furthermore, the pipe mouth of the automatic cleaning device is installed on the bearing end cover and connected to the output and input pipes at the end cover. During the cleaning process, the outer ring end cover and the bearing seat of the bearing are fixed, and the inner ring can rotate freely so that more positions can be cleaned; large-diameter inlets and outlets are respectively opened on the bearing end cover to connect the leather output pipe and the input pipe, which can effectively discharge large pieces of waste grease and facilitate multi-directional cleaning of the cleaning nozzle, and recycle the waste liquid.

[0006] Furthermore, the front end of the nozzle is made of a soft PVC hose. When the water pressure is slightly higher, the spraying direction is random, which can effectively clean the grease adhering to the corners.

[0007] Furthermore, an oil retaining groove is provided on the surface of the oil retaining plate, which can effectively reduce the large particles of grease falling into the cleaning agent, and a maze outlet is provided at the outlet of the oil retaining plate, which will secondarily prevent the grease from falling into the cleaning agent.

[0008] Furthermore, the discharge valve at the bottom of the cleaning agent storage tank is switched by a signal start.

[0009] Furthermore, the flow rate controller can control the discharge speed of the cleaning agent and adjust the motor pump power by transmitting a signal to the control system to avoid excessive flow rate causing water pressure to increase and causing damage to the inside of the bearing.

[0010] Furthermore, the iron measuring instrument, flow rate controller and cleanliness detection device all transmit signals to the control system via antennas.

[0011] By adopting the above technical solution, the cleaning device of the present invention is a system integrating a motor pump, a circulation pipeline, filtration, grease quality detection, flow rate control, and cleanliness detection. It is necessary to ensure that the bearing can rotate slowly during the cleaning process so that more positions can be cleaned. The selection of cleaning agents needs to be matched with the type of grease. Various data detected by the sensor ensure the quality of cleaning. In addition, the device is automatically controlled without human intervention; the quality of grease inside the bearing can be understood in time; downtime is reduced, and downtime maintenance costs are reduced; waste liquid is recycled and reused to avoid waste and is environmentally friendly and hygienic.

[0022] First, the iron content in the grease is detected by a portable grease iron meter 9, and the detection data is directly transmitted to the control system 10. The control system 10 stores the iron content standard and automatically determines whether the grease inside the bearing needs to be cleaned to facilitate the replacement of clean grease. The cleaning agent in the first storage compartment 15 in the storage box 5 is sucked out through the built-in pipe 14 by the motor pump 4, and is transported to the mounting hole at the end cover 20 through the third leather tube 6 and the first leather tube 1, and is sprayed out by the two small nozzles 121 on the nozzle 12 for cleaning. The waste cleaning agent after cleaning will enter the second storage compartment 16 of the storage box through the bottom output pipe. An oil baffle 13 is installed in the compartment, which can effectively filter large pieces of grease to avoid clogging of the pipeline during secondary use. The cleanliness detection device 8 in the storage box 5 will detect the cleanliness of the waste cleaning agent and transmit the data to the control system 10. The control system 10 will determine whether the waste cleaning agent can still be reused. If not, it will be directly discharged from the drain valve 17 at the bottom of the box.

[0023] In the specific implementation process, the pipe mouths 1 and 2 of the automatic cleaning device are installed on the bearing end cover 20 of the shaft and bearing assembly 11, and connected to the newly opened end cover hole 21 at the end cover 20. During the cleaning process, the bearing outer ring 18 and the end cover 20 are fixed, and the inner ring 19 can rotate freely so that more positions can be cleaned; large-diameter end cover holes 21 are respectively opened on the bearing end cover 20, which are respectively connected to the first leather tube 1 and the second leather tube 2, which can effectively discharge large pieces of waste grease and facilitate multi-directional cleaning of the small nozzle 121, and recycle the waste liquid.

[0024] The small nozzle 121 at the front end of the nozzle 12 is made of a soft PVC hose. When the water pressure is slightly higher, the spray direction is random, which can effectively clean the grease adhering to the corners.

[0025] During the waste liquid recovery process, an oil baffle plate 13 is provided in the second storage chamber 16, and an oil baffle groove is provided on its surface, which can effectively reduce the large particles of grease falling into the cleaning agent, and a maze outlet is provided at the outlet of the oil baffle plate 13, which will secondarily block the grease from falling into the cleaning agent.

[0026] During the cleaning process, the flow rate controller 3 can control the discharge speed of the cleaning agent and adjust the power of the motor pump 4 by sending a signal to the control system 10 to avoid excessive flow rate causing water pressure to increase and causing damage to the inside of the bearing.

[0027] The grease aerial cleaning device is very simple to install and use. Just connect the bearing end cover and the cleaning device designed according to the requirements. After the power is turned on, the grease test tube taken from the bearing is inserted into the iron meter for self-testing, and the data is transmitted to the control system for analysis. If cleaning is required, the control system will start the motor pump and transmit the cleaning agent to the end cover through the pipeline to clean the bearing. Only one professional is needed to monitor on site
