Description

Technical Field

[0001] The invention relates to the technical field of equipment maintenance, and in particular to an automatic chain maintenance technology. Background Art

[0002] In industrial production equipment, chain transmission is widely used in many scenarios due to its long transmission distance, low power attenuation, simple drive device and other characteristics. However, as the chain is used for a long time, the sludge formed by the tiny metal chips mixed with lubricating oil from mechanical wear adheres to the chain and is difficult to remove. The attached sludge runs with the mechanism for a long time, aggravating the wear of the mechanical chain. Because the chain is installed in the guide groove, its mechanical structure design only provides a daily lubricating oil filling port, which cannot quickly clean up the large amount of sludge attached to the chain, and the installation position of the chain is generally not conducive to quick disassembly and maintenance.

[0003] At present, all automatic chain maintenance devices on the market are automatic lubrication systems, which realize automatic filling of lubricants within a cycle in different forms, mainly gravity filling and air pressure difference filling. However, the existing automatic lubrication system can only realize two functions: automatic filling of lubricants and lubricant exhaustion alarm, and cannot clean the tiny metal chips attached to the chain. Take a certain brand of pneumatic single-point automatic lubricator as an example. It consists of a lubricator mounting base and a pressurized lubricant storage bottle. After the pressurized lubricant storage bottle is installed on the lubricator base, the compressed gas inside the pressurized bottle body begins to slowly press out the lubricant, and the lubricant drips onto the chain through the drip port of the base, realizing automatic lubrication of the chain within a certain period. There are two disadvantages: on the one hand, if the chain is not cleaned and simply lubricated, the sludge attached to the chain will prevent the lubricant from covering the moving parts such as the shaft, and the lubrication effect will gradually weaken over time; on the other hand, once the pressurized lubricant storage bottle is put into use, the pressure leakage cannot be stopped. Regardless of whether the equipment is in operation, the lubricant consumption is uncontrolled and continues, which is very unfavorable for cost control. Summary of the invention

[0004] In order to solve the problem that the existing automatic chain maintenance device cannot quickly clean the oil sludge on the chain surface, the present invention proposes an automatic chain maintenance device.

[0031] To make the technical solutions of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. It should be noted that the following embodiments are only for better understanding the technical solutions of the present invention and should not be construed as a limitation of the present invention.

[0032] Embodiment 1.

[0033] This embodiment provides an automatic chain maintenance device, including a control system, a vibration cleaning system, a cleaning oil circulation spraying system, and an automatic lubrication system;

[0034] The vibration cleaning system is used to drive the chain 5 to vibrate, so that the attachments on the surface of the chain 5 become loose or fall off;

[0035] The cleaning oil circulation spraying system is used to spray oil and gas on the vibrating chain 5 to carry away the loose attachments on the surface of the chain 5 and achieve the cleaning of the chain 5;

[0036] The automatic lubrication system is used to spray lubricating oil on the chain 5 after cleaning to achieve the lubrication of the chain 5;

[0037] The control system is used to control the operation of the vibration cleaning system and the automatic lubrication system according to a predetermined mode to achieve the maintenance of the chain 5.

[0038] The maintenance device described in this embodiment can not only achieve all the functions of the existing automatic lubricator, but also realize the control of lubricant filling and the automatic non-detachable cleaning of the chain, reducing the consumption cost of lubricant and the mechanical wear of the chain, as well as the maintenance cost and maintenance man-hours.

[0039] Embodiment 2.

[0040] This embodiment is a further illustrative example of Embodiment 1. The control modes of the control system include a regular maintenance mode, a quantitative maintenance mode, and a manual maintenance mode. In the regular maintenance mode, the control system performs timing, and controls to execute a maintenance once every time the preset maintenance cycle is reached. In the quantitative maintenance mode, the control system records the running mileage of the chain 5, and controls to execute a maintenance once every time the preset maintenance mileage is reached. In the manual maintenance mode, the control system controls to execute a maintenance once after receiving a manual trigger signal.

[0041] Embodiment 3.

[0042] This embodiment is a further illustrative example of Embodiment 2. As Figure 1 shown, the vibration cleaning system includes an ultrasonic generator, an ultrasonic diaphragm 3, a driven vibration wheel 1, and a flexible connection support 4. The ultrasonic generator is placed in the base 2. The ultrasonic diaphragm 3 is connected to the ultrasonic generator through the flexible connection support 4. The ultrasonic diaphragm 3 is used to receive the ultrasonic waves emitted by the ultrasonic generator and convert the ultrasonic energy into mechanical waves to drive the driven vibration wheel 1 to vibrate. The driven vibration wheel 1 drives the chain 5 to vibrate by engaging with the chain 5.

[0043] In the vibration cleaning system shown in this embodiment, the ultrasonic generator emits ultrasonic waves to the ultrasonic diaphragm 3 at a very close distance. Since the connection between the driven vibration wheel 1 and the flexible connection support 4 is flexible, the passively vibrating diaphragm converts the energy into mechanical waves to drive the driven vibration wheel to vibrate with a small amplitude and high frequency. The chain vibrates at the same frequency and similar amplitude as the driven vibration wheel at the engagement point due to being pressed and engaged with the driven vibration wheel. The oil sprayed at the engagement point receives the energy of high-frequency mechanical waves due to contact with the vibrating driven vibration wheel and the chain. Based on the "cavitation effect" of ultrasonic waves, in this case, countless tiny bubbles will continuously generate and disappear on the surface of the oil and the chain. The shock waves caused by the tiny bubbles bombard the attachments on the surface of the chain, making them loose and fall off, and being washed away by the continuously sprayed oil.

[0044] Embodiment 4.

[0045] This embodiment is a further illustrative example of Embodiment 3. The flexible connection support 4 is made of rubber material.

[0046] Embodiment 5.

[0047] This embodiment further illustrates Embodiment 3. The vibration cleaning system further includes a photoelectric sensor, which is arranged in the base 2 and is used to sense the number of rotations of the driven vibration wheel 1 and transmit a signal to the control system to calculate the running mileage of the chain 5.

[0048] The device in this embodiment includes a photoelectric sensor. By irradiating the characteristic holes on the surface of the driven vibration wheel and converting the number of signal flashes into the number of rotations of the driven vibration wheel, when the control system calculates that the running mileage of the chain is greater than or equal to the preset maintenance mileage, the controller starts a cleaning and lubrication process once to realize the maintenance work in the quantitative mode.

[0049] Embodiment 6.

[0050] This embodiment further illustrates Embodiment 1. As Figure 1 shown, the cleaning oil circulating injection system includes a cleaning oil spray gun 14, an air spray gun 17, a cleaning oil return tank 6, a cleaning oil storage tank 11, a cleaning oil filter 12, a cleaning oil pump 13, and a first compressed air pipe 7; the cleaning oil filter 12 is used to filter the oil liquid extracted by the cleaning oil pump 13 from the cleaning oil storage tank 11 and then enter the cleaning oil pump 13, the cleaning oil pump 13 is used to transport the oil liquid to the cleaning oil spray gun 14, and the cleaning oil spray gun 14 is used to spray the oil liquid onto the chain 5 at the meshing part; the first compressed air pipe 7 transports compressed gas to the air spray gun 17, and the air spray gun 17 is used to blow air onto the chain 5 after passing through the meshing part, so that the blown-off oil liquid falls into the cleaning oil return tank 6 and then flows into the cleaning oil storage tank 11.

[0051] Embodiment 7.

[0052] This embodiment further illustrates Embodiment 6. The cleaning oil circulating injection system further includes a pressure sensor, which is arranged on both sides of the replaceable filter element in the cleaning oil filter 12 and is used to collect the pressure data difference before and after the replaceable filter element and transmit it to the control system to determine whether the filter element needs to be replaced.

[0053] The oil liquid extracted by the cleaning oil pump 13 from the cleaning oil storage tank 11 will be filtered by the cleaning oil filter 12 before entering the pump body, and metal powders, debris, etc. in the oil liquid are intercepted in the replaceable filter element of the filter. In this embodiment, pressure sensors are integrated on both sides of the filter element, and the controller collects the data difference of the pressure sensors before and after the filter element to determine whether the filter element life is exhausted, so as to avoid affecting the maintenance effect of the device due to filter element failure.

[0054] Embodiment 8.

[0055] This embodiment further illustrates Embodiment 1. As Figure 1As shown in the figure, the automatic lubrication system includes a lubricant storage tank 10, a lubricant spray gun 15, a second compressed air pipe 8, and a lubricating oil pipe 9; the lubricant spray gun 15 is used to atomize the gas and lubricating oil output from the second compressed air pipe 8 and the lubricating oil pipe 9, and then spray it on the surface of the chain 5 to complete the lubrication of the chain 5.

[0056] Example 9.

[0057] This embodiment provides an automatic chain maintenance method, which applies the automatic chain maintenance device described in any one of Embodiments 1-8. The method includes the following steps:

[0058] S1. Select the control mode of the control system. The controller continuously monitors the trigger signal. When a manual trigger signal is received or the preset maintenance cycle or maintenance mileage is reached, the cleaning oil circulation injection system is started. The cleaning oil pump 13 extracts the oil liquid filtered by the cleaning oil filter 12 and sprays it at the engagement position between the driven vibration wheel 1 and the chain 5.

[0059] S2. After a preset delay time, the vibration cleaning system is started. The oil liquid sprayed at the engagement position loosens or falls off the attachments on the surface of the chain 5 under the vibration action.

[0060] S3. After the chain 5 passes through the engagement position and continues to move forward, the air spray gun 17 sprays the cleaned chain 5, blowing the oil liquid and surface attachments on the chain 5 into the cleaning oil return tank 6, and then flowing into the cleaning oil storage tank 11 for recycling.

[0061] S4. The chain 5 continues to move forward, and the automatic lubrication system is started. Lubricating oil and compressed air are injected into the lubricant spray gun 15, atomized and sprayed on the surface of the chain 5 to complete the lubrication of the chain 5.

[0062] The maintenance method described in this embodiment can achieve fine cleaning and automatic lubrication of the chain without disassembling the chain mechanism. By simply setting the cleaning parameters, the chain can be self-maintained within its service life, solving the problem of excessive wear caused by insufficient chain cleaning, which affects the service life, and reducing or eliminating the number of disassembly and maintenance times during the chain life cycle.
