Description

Technical Field

[0001] This utility model belongs to the technical field of lubrication devices, and specifically relates to a lubrication device. Background Technology

[0002] In the operation of industrial equipment (such as bucket elevators and speed reducers), the bearing lubrication system is crucial to the stability and lifespan of the equipment. The lubrication system needs to periodically inject lubricating oil into the bearings to reduce friction, lower wear, and prevent overheating. For example, the two ends of the tail wheel of a bucket elevator are typically supported on bearing housings by bearings. The bearing housings are fixed to the inner wall of the tail bucket box, and the inner holes are inlaid with copper sleeves or rolling bearings to reduce friction between the shaft and the bearing housings, ensuring smooth rotation of the tail wheel. When the head wheel is driven by the drive components and moves the traction components, the tail wheel is connected to the tail bucket box through the bearing housings and rotates under the friction or mechanical meshing force of the traction components, thus maintaining the continuous operation of the entire system. During use, the bearings need to be regularly lubricated to reduce friction and wear, lower operating temperature, prevent corrosion and rust, extend equipment life, and ensure operational stability.

[0003] Existing technologies use a grease cup to replenish lubricant to the tail wheel. For example, an electric push rod and piston rod are installed on the grease cup to push the lubricant into the bearing's oil hole. Through a preset program, the automatic grease cup can precisely release grease at fixed intervals (e.g., every 8 hours, every 24 hours), ensuring the bearing receives continuous and adequate lubrication. This avoids the randomness of manual grease replenishment, extends bearing life, and reduces wear or failure caused by insufficient lubrication. However, the above lubrication devices have significant drawbacks in low-temperature environments:

[0004] 1. Low temperatures lead to poor lubricant flow: In winter or cold regions, the viscosity of lubricating oil increases significantly as the temperature decreases, resulting in poorer flow. When an electric actuator or hydraulic cylinder drives a piston rod to move the lubricating oil, the high viscosity of the lubricating oil generates greater flow resistance, causing the piston rod to have to overcome higher internal friction to move. This not only increases the risk of wear on mechanical parts but may also cause overload of the drive components, or even lead to motor burnout or hydraulic system failure.

[0005] 2. Insufficient lubrication leading to equipment damage: If lubricating oil cannot be smoothly injected into the bearing due to low temperature, the bearing may experience dry friction due to lack of lubrication, resulting in surface wear, overheating, or even seizing, which seriously affects the operating efficiency of the equipment and increases downtime maintenance costs. Utility Model Content

[0006] In view of the above problems, the purpose of this utility model is to provide a lubrication device to solve the problems mentioned in the background art.

[0007] This utility model provides a lubrication device with an oil filling cylinder, including an internal chamber for containing lubricating oil and an oil filling nozzle at one end that matches the oil hole of a bearing; an oil replenishment assembly including a piston rod and an electric push rod for driving the piston rod to push lubricating oil out of the oil filling cylinder; a pressure sensor mounted on the piston rod for real-time detection of the pressure value when the piston rod pushes the lubricating oil; a temperature sensor located on the oil filling cylinder for detecting the temperature of the lubricating oil; a heating assembly mounted on the outer wall of the oil filling cylinder for heating the lubricating oil; and a control assembly electrically connected to the pressure sensor and the temperature sensor for controlling the operation of the heating assembly based on the pressure signal detected by the pressure sensor and the temperature signal detected by the temperature sensor.

[0008] Preferably, it further includes: a position sensor, which is installed at the end of the piston rod away from the oil filling cylinder, for detecting the distance from the end of the piston rod to the oil filling cylinder; the control component also calculates the level of lubricating oil in the oil filling cylinder based on the distance signal detected by the position sensor and controls the operating state of the heating component.

[0009] Preferably, the heating assembly includes: a heating jacket surrounding the outer wall of the heating jacket for heating the oil cylinder; and a temperature controller for adjusting the power of the heating jacket according to the temperature signal detected by the temperature sensor.

[0010] Preferably, the heating sleeve has a viewing frame with the same axial length as the oil filling cylinder, and a scale line is provided on the outer side of the oil filling cylinder, at the position directly opposite the viewing frame.

[0011] Preferably, the piston rod is detachably connected to the electric push rod.

[0012] Preferably, the bucket elevator housing is provided with a support assembly for fixing the refueling cylinder, and the support assembly includes:

[0013] The first support frame is fixedly installed on the bucket elevator housing and is used to support the refueling cylinder;

[0014] The second support frame is located on the first support frame, and the refueling cylinder is slidably inserted into the insertion hole in the middle of the second support frame to restrict the lateral movement of the refueling cylinder.

[0015] The beneficial effects of this invention are as follows: By monitoring the pressure of the piston rod oil in real time through a pressure sensor, and judging the state of the lubricating oil based on the lubricating oil temperature detected by a temperature sensor, when the pressure value exceeds a preset threshold and the temperature sensor detects a temperature below a preset threshold, the control component controls the heating component to preheat the lubricating oil in a low-temperature environment based on the pressure and temperature signals, thereby reducing its viscosity and ensuring smooth injection into the bearing under cold working conditions, reducing mechanical wear, realizing intelligent lubrication process, reducing manual intervention, and improving work efficiency and safety.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0024] like Figure 1-6As shown, a lubrication device includes a filling cylinder 1 with an internal chamber 2 for containing lubricating oil. One end of the filling cylinder 1 is provided with a filling nozzle 4 adapted to the oil hole of a bearing 3. An oil replenishment assembly is provided on the filling cylinder 1 to push lubricating oil out of the filling cylinder 1 during replenishment. This oil replenishment assembly includes a piston rod 5 and an electric push rod 6 (or other power components such as a hydraulic cylinder) for driving the piston rod 5. Because the viscosity of lubricating oil increases due to the decrease in ambient temperature in winter and cold regions, when the electric push rod 6 is activated and attempts to push the piston rod 5, the increased flow resistance of the high-viscosity lubricating oil requires the piston rod 5 to overcome greater internal friction to move, easily leading to mechanical wear. Therefore, this technical solution installs a heating assembly 9 on the filling cylinder 1 to heat the lubricating oil. A pressure sensor 7 is also installed on the piston rod 5, and a temperature sensor 8 is installed on the filling cylinder 1. The pressure sensor 7 is used to detect the pressure value when the piston rod pushes the lubricating oil in real time, and the temperature sensor 8 is used to detect the temperature of the lubricating oil. The pressure sensor 7 and temperature sensor 8 are electrically connected to the control component. The control component controls the operation of the heating component 9 based on the pressure signal detected by the pressure sensor 7 and the temperature signal detected by the temperature sensor 8. The heating component 9 includes a heating sleeve 11 surrounding the outer wall of the heating sleeve 11 for heating the oil cylinder 1, and a heating sleeve 11 for adjusting the power of the heating sleeve 11 based on the temperature signal detected by the temperature sensor 8. Specifically, when the pressure sensor 7 detects that the pressure value exceeds a first preset threshold and the temperature is lower than a second preset threshold, the heating component 9 is started and the maximum power is maintained. To improve the safety of this technical solution, it is also set that when the temperature reaches the target value and the pressure value continues to be abnormal for more than a set time (e.g., 3 minutes), heating is stopped and an alarm is triggered. In order to realize this technical solution, an alarm module (audio and / or light alarm) and a timing module are also set in the control component. The alarm module and the timing module are existing technologies and are not the focus of this utility model, so they will not be described in detail here. This technical solution automatically preheats the lubricating oil in low-temperature environments, reducing its viscosity and ensuring smooth injection into the bearing 3 even in cold conditions, thus reducing mechanical wear and improving the intelligence of oil replenishment. To facilitate the installation and removal of the oil filling nozzle 1, the piston rod 5 is detachably connected to the electric push rod 6. Specifically, as shown... Figure 1 As shown, the electric push rod 6 is installed on the bucket elevator housing. Its telescopic end is connected to the piston rod 5 through a pressure plate. A pressure sensor 7 is installed at the bottom of the pressure plate, and a connecting sleeve is installed at the bottom of the pressure sensor 7. The connecting sleeve is connected to the piston rod 5 by bolts 14. The detachable structure allows for the individual replacement of the piston rod 5 or the electric push rod 6, reducing maintenance costs (for example, when the piston rod 5 is worn, it is not necessary to replace the entire drive assembly). It also supports the quick replacement of the piston rod 5 specification according to different lubrication requirements (such as thrust and stroke), improving the versatility of the device.

[0025] To facilitate the installation of the lubrication nozzle 1, a support assembly is provided on the bucket elevator housing. This support assembly includes a first support frame 15 fixedly installed on the bucket elevator housing for supporting the lubrication nozzle 1, and a second support frame 16 located on the first support frame 15. The lubrication nozzle 1 is slidably inserted into the insertion hole in the middle of the second support frame 16 to restrict the lateral movement of the lubrication nozzle 1. The double fixation of the lubrication nozzle 1 by the first support frame 15 and the second support frame 16 prevents vibration from causing the lubrication nozzle 1 to tilt or fall off, ensuring that the oil filling nozzle is aligned and accurately inserted into the oil hole of the bearing 3. At the same time, the support assembly is made of high-strength materials (such as stainless steel or carbon steel) to withstand the vibration and impact during the operation of the bucket elevator, ensuring that the lubrication device works stably under harsh working conditions.

[0026] Furthermore, such as Figure 3-4 As shown, to prevent the heating assembly 9 from burning dry and damaging the refueling cylinder 1, a position sensor 10 (such as an ultrasonic ranging sensor or an infrared ranging sensor) is also installed. This sensor is installed at the end of the piston rod 5 furthest from the refueling cylinder 1 and is used to detect the distance from the end of the piston rod 5 to the refueling cylinder 1. The position sensor 10 is electrically connected to the control assembly and is used to calculate the lubricating oil level in the refueling cylinder 1 based on the distance signal detected by the position sensor 10. For example, when the end of the piston rod 5 inside the refueling cylinder 1 (the head end) is pressed against the inner top wall of the refueling cylinder 1, it indicates that the lubricating oil level in the refueling cylinder 1 is full. At this time, the distance detected by the position sensor 10 is... The distance value is 50CM, the lubricating oil is 500ML, and if the amount of oil added each time is 2ML, the piston rod 5 moves down 0.2 cm each time. As the number of oil additions increases, after ten oil additions, the head end of the piston rod 5 gradually moves down 2 cm, away from the inner fixed wall of the oil filling bottle 1. Conversely, the tail end of the piston rod 5 (the end away from the oil filling bottle 1) gradually approaches the oil filling bottle 1. At this time, the distance value detected by the position sensor 10 is 48CM. After several oil additions, the amount of lubricating oil gradually decreases. According to the preset program, when the liquid level is lower than the preset safety value (such as 20ML), the heating component 9 is prohibited from being started and the staff is prompted to add oil. Furthermore, to facilitate staff observation of the remaining lubricating oil level in the refill cylinder 1 during inspections, the refill cylinder 1 is made of a transparent material (polycarbonate or polymethyl methacrylate) or a semi-transparent material (modified polypropylene or stainless steel with a transparent window). A viewing frame 12, with the same axial length as the refill cylinder 1, is provided on the heating jacket 11. A scale line 13 is located on the outer side of the refill cylinder 1, directly opposite the viewing frame 12. The viewing frame 12 allows users to directly observe the lubricating oil level and quickly read the remaining oil level using the scale line 13, without the need for additional tools or machine shutdown for inspection. The viewing frame 12 is integrated into the outer side of the heating jacket 11, occupying no extra space. Moreover, the material of the viewing frame 12 (such as transparent polycarbonate) is high-temperature resistant, anti-aging, and not easily deformed over long-term use.
