[0031] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0033] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0034] This embodiment provides a small, portable lubricating oil filling machine, such as... Figure 1As shown, it includes a housing 100, a drive mechanism 200, and an auxiliary mechanism 300, which are used to solve the problems of existing lubricating oil filling equipment being bulky, heavy, and inconvenient to move, resulting in low work efficiency and being unsuitable for outdoor or long-distance work, as well as poor oil filling accuracy and lubricating oil cleanliness.

[0035] Depend on Figure 1 As can be seen, the drive mechanism 200 is located at the bottom of the housing 100, and the auxiliary mechanism 300 is located on the side of the housing 100. A remote control module is installed inside the housing 100, enabling the housing 100 to move automatically without manual handling by remotely controlling the drive mechanism 200. The auxiliary mechanism 300 is used to replace operators in performing oiling and maintenance on the equipment. In work environments with limited space where operators cannot easily access, the oiling gun can be installed on the auxiliary mechanism 300, and then the housing 100 can be moved to the equipment requiring maintenance and oiling can be performed using the remotely controlled drive mechanism 200.

[0036] See Figure 2 and Figure 3 As can be seen, the internal structure of the lubricating oil filling machine's housing 100 is compact. A lifting ring is installed on the top of the housing 100 for hoisting the lubricating oil filling machine. A display touchscreen 101 is installed on the front of the housing 100, and a pressure gauge 102 is installed at the upper left corner of the front of the housing 100 to display the pressure inside the oil filling pipeline. A through-hole is provided on the side of the housing 100; one end of the oil filling pipeline connects to a quick-connect coupling 109 inside the housing 100 via the through-hole, and the other end connects to the oil filling gun.

[0037] like Figure 3 As shown, an oil tank 105 is also installed inside the housing 100. A handle is located on the rear side of the oil tank 105. A first filter 103 and an air filter 104 are installed on the top. The air filter 104 is installed on the side closer to the handle, while the first filter 103 is installed on the side farther from the handle. The first filter 103 is a coarse filter using a 25-micron filter element, used to filter larger particles in the lubricating oil. The outlet of the first filter 103 is connected to the inlet of the oil pump via an oil pipe. The oil pump motor 106 is connected to the oil pump and drives it. The outlet of the oil pump is connected to a check valve and a flow meter 107. A pressure gauge 102 is located between the check valve and the flow meter 107. A second filter 108 is installed between the flow meter 107 and the quick-connect coupling 109. The second filter 108 is a fine filter using a 1-micron filter element, effectively removing minute impurities from the lubricating oil.

[0038] Both the first filter 103 and the second filter 108 are equipped with differential pressure monitoring devices. When the filter element is clogged, the differential pressure will increase. When the differential pressure exceeds the set value, the differential pressure monitoring device will send an alarm signal to the control system. The operator will then replace the filter element in time according to the alarm signal to ensure the cleanliness of the lubricating oil and the normal operation of the filling machine.

[0039] The quick-connect coupling 109 connects to one end of the oil pipeline 110, enabling a quick connection between the internal oil pipeline circuit and the oil pipeline 110. The controller 112 is installed inside the housing 100, facing the oil tank 105, while the battery 111 is located below the display touchscreen 101. The controller 112 is a Siemens S7-1200 series PLC, which features high processing power and rich control functions.

[0040] The controller 112 acquires the lubricating oil flow signal monitored in real time by the flow meter 107 through the analog input module. After processing by the control algorithm preset inside the controller 112, it controls the opening and closing of the solenoid valve and the speed of the oil pump to achieve precise control of the lubricating oil filling amount. The oil filling accuracy can be controlled within ±0.1L.

[0041] The drive mechanism of the lubricating oil filling machine 200 Figure 4 As shown, the drive mechanism 200 mainly includes a top plate 201, a left outrigger 202, a hydraulic cylinder 203, a travel motor 204, a drive wheel 205, a steering linkage 206, a transmission pin 207, an electric cylinder 208, a right outrigger 210, and a rear outrigger 211. The structure of the right outrigger 210 is as follows... Figure 6 As shown, the right outrigger 210 mainly includes an outrigger body 2101, a cylinder seat 2102, a rotating pin 2103, a connecting rod pin 2104, a steering tie rod 2105, and a limiting hole 2106. The structures of the left outrigger 202 and the rear outrigger 211 are similar to those of the right outrigger 210. Taking the right outrigger 210 as a reference, the left outrigger 202 lacks the steering tie rod 2105, while the rear outrigger 211 lacks the rotating pin 2103, the connecting rod pin 2104, and the steering tie rod 2105.

[0042] See Figure 4 and Figure 6 The right outrigger 210 has a U-shaped outrigger body 2101, with two cylinder seats 2102 formed on the inner side of its top. The two cylinder seats 2102 are parallel to each other and arranged along the width direction of the outrigger body 2101. The bottom of the outrigger body 2101 is machined with a limiting hole 2106, the diameter of which is equal to the outer diameter of the hydraulic cylinder 203, to limit the axial movement of the hydraulic cylinder 203 along the pin shaft.

[0043] The cylinder seat 2102 has a through hole for mounting the hydraulic cylinder 203. A fixing seat 2031 is welded to the end of the hydraulic cylinder 203 furthest from the hydraulic rod. The fixing seat 2031 has a through hole of the same diameter as the cylinder seat 2102. The hydraulic cylinder 203 passes through a limiting hole 2106 inside the outrigger body 2101. The fixing seat 2031 is connected to the cylinder seat 2102 via a pin. The mounting method of the hydraulic cylinders 203 on the left outrigger 202 and the rear outrigger 211 is exactly the same as that on the right outrigger 210. The extension and retraction of the hydraulic rod in the hydraulic cylinder 203 allows the ground clearance of the drive mechanism 200 to be adjusted, improving the drive mechanism 200's ability to pass over obstacles. Furthermore, each hydraulic cylinder 203 mounted on the outrigger can be controlled individually.

[0044] The hydraulic rod of the hydraulic cylinder 203 has a wheel groove 2032. The drive wheel 205 is installed in the wheel groove 2032 by a pin. The travel motor 204 is installed on the side wall of the hydraulic rod in the hydraulic cylinder 203. The output end of the travel motor 204 is fixedly connected to the pin of the drive wheel 205.

[0045] Therefore, the battery 111 inside the housing 100 supplies power to the walking motor 204. The rotation of the output shaft of the walking motor 204 causes the drive wheel 205 to move, thereby moving the lubricating oil filling machine. The movement of the lubricating oil filling machine can be realized through the remote control module.

[0046] The drive mechanism 200 is connected to the housing 100 via a top plate 201, which has two through holes along its width. Rotating pins 2103 are formed on the tops of the left support leg 202 and the right support leg 210. The left and right support legs 202 and 210 are mounted in the through holes via bearings, thus connecting to the top plate 201. The rear support leg 211 is bolted to the top plate 201. Therefore, the left and right support legs 202 and 210 rotate, enabling the drive mechanism 200 to steer.

[0047] For the steering principle of drive mechanism 200, please refer to [link / reference]. Figure 5 The left outrigger 202 and the right outrigger 210 are rotatably connected to the top plate 201. The electric cylinder 208 is installed at the bottom of the top plate 201 via a clamp 209. The shaft of the electric cylinder 208 is connected to the steering tie rod 2105 of the right outrigger 210 via a transmission pin 207. The two ends of the steering linkage 206 are respectively installed on the connecting pins 2104 of the left outrigger 202 and the right outrigger 210. The left outrigger 202 and the right outrigger 210 are driven by the steering linkage 206.

[0048] The extension shaft of the electric cylinder 208 drives the right support leg 210 to rotate counterclockwise via the transmission pin 207. This counterclockwise rotation of the right support leg 210 causes the steering linkage 206 to move towards the left support leg 202, thereby driving the left support leg 202 to rotate counterclockwise synchronously with the right support leg 210. Using the forward direction of the drive mechanism 200 as a reference, the drive mechanism 200 then turns to the left. Similarly, to turn the drive mechanism 200 to the right, the extension shaft of the electric cylinder 208 retracts, driving the right support leg 210 to rotate clockwise via the transmission pin 207. The right support leg 210 then drives the left support leg 202 to rotate clockwise synchronously via the steering linkage 206, thus achieving a right turn for the drive mechanism 200.

[0049] Figure 7 and Figure 8 This is a schematic diagram of the auxiliary mechanism 300 in the lubricating oil filling machine, in which... Figure 8 This is another view of the auxiliary mechanism 300. As shown in the figure, the auxiliary mechanism 300 mainly consists of a slide 301, an adjusting seat 302, an adjusting motor 303, a lead screw motor 304, a slide groove 305, a lead screw 306, a slide block 307, a support connecting rod 308, and an auxiliary oiling assembly 309. The adjusting seat 302 is bolted to the side of the housing 100, and is located on the same side as the quick-change connector 109 and the oil supply pipe 110. The slide 301 is mounted on the adjusting seat 302 and forms a sliding connection with the adjusting seat 302. A rack is machined on the left side wall of the adjusting seat 302, and the gear meshes with the rack. The output shaft of the adjusting motor 303 passes through the slide 301 and is fixedly connected to the gear. The adjusting motor 303 is mounted on the outside of the slide 301. By driving the gear to rotate through the adjustment motor 303, the gear meshes with the rack, realizing the up and down movement of the slide 301, thereby enabling the auxiliary oiling assembly 309 to be adjusted up and down.

[0050] The slide groove 305 is fixedly connected to the slide bracket 301 and installed on the right side of the adjusting motor 303. The lead screw 306 is placed inside the slide groove 305 and its two ends are connected to the slide groove 305 through bearings. The two sides of the slide block 307 are attached to the side wall of the slide groove 305, and the bottom of the slide block 307 is sleeved on the lead screw 306 and threadedly connected to the lead screw 306.

[0051] A connecting rod seat 3092 supporting the connecting rod 308 is provided on the side of the slide 307 away from the lead screw 306. One end of the supporting connecting rod 308 is mounted on the slide 307 via a pin, and the other end is also mounted on the connecting rod seat 3092 in the auxiliary lubrication assembly 309 via a pin. The auxiliary lubrication assembly 309 is mounted on the top of the slide groove 305 via a hinge 310. The lead screw motor 304 is mounted on the bottom of the slide groove 305, and its output shaft passes through the slide groove 305 and is fixedly connected to the lead screw 306.

[0052] The structure of the auxiliary oil injection component 309 is as follows: Figure 9As shown, the auxiliary oiling assembly 309 mainly includes a square tube 3091 and an oil gun holder 3095. A camera 3094 is installed on one end face of the square tube 3091 for observing the oiling position during remote operation. Two connecting rod seats 3092 are formed at the bottom of the square tube 3091, and a receiving groove 3093 is machined between the two connecting rod seats 3092. The receiving groove 3093 extends towards the camera 3094 and passes through the end face of the square tube 3091. The oil gun holder 3095 is located at the top of the square tube 3091 and adjacent to the camera 3094. The oil gun holder 3095 is machined with a slot for mounting the oil gun.

[0053] Figure 7 and Figure 8 To assist the working status of mechanism 300, Figure 1 The auxiliary mechanism 300 is in a non-operating state. Figure 7 Taking this as an example, the lead screw motor 304 drives the lead screw 306 to rotate, and the slide block 307 slides downward in the slide groove 305. The movement of the slide block 307 causes the support connecting rod 308 to move closer to the slide groove 305. The auxiliary oil injection assembly 309 rotates towards the slide groove 305 under the drive of the support connecting rod 308. Finally, the bottom of the square tube 3091 in the auxiliary oil injection assembly 309 fits into the slide groove 305, and the support connecting rod 308 is placed in the storage slot 3093. The auxiliary mechanism 300 switches to a non-working state, which facilitates passage through narrow spaces.

[0054] Combination Figure 1 , Figure 4 as well as Figure 7 The working process of the lubricating oil filling machine is explained as follows: First, turn on the power switch. The battery 111 inside the housing 100 supplies power to the display touch screen 101, controller 112, oil pump motor 106, travel motor 204, electric cylinder 208, adjusting motor 303, lead screw motor 304, camera 3094, remote control module, and differential pressure monitoring device. By remotely controlling the travel motor 204, the drive wheel 205 rotates, moving the entire lubricating oil filling machine to the location where lubricating oil needs to be added, without manual handling. Then, connect the oil delivery pipe 110 to the quick-connect coupling 109.

[0055] The lubricating oil filling amount is set on the touch screen 101, and the oil pump motor 106 is started to drive the oil pump. The lubricating oil is drawn from the oil tank 105 and filtered by the first filter 103 and the second filter 108, and finally sprayed out by the oil gun. During the lubricating oil filling process, the controller 112 collects the lubricating oil flow signal monitored in real time by the flow meter 107 through the analog input module. After processing by the preset control algorithm inside the controller 112, it precisely controls the opening and closing of the solenoid valve and the speed of the oil pump, so as to achieve precise control of the lubricating oil filling amount. The filling accuracy can be controlled within ±0.1L.

[0056] When entering a work environment with limited space and inconvenient access for operators, the oil gun is installed in the oil gun holder 3095, and then the drive mechanism 200 is controlled to bring the lubricating oil dispenser into the work area. If an obstacle is encountered during travel, the hydraulic rod of the hydraulic cylinder 203 extends, increasing the ground clearance of the drive mechanism 200 and preventing the obstacle from scraping the bottom of the drive mechanism 200. Upon reaching the location where lubricating oil needs to be dispensed, the lead screw motor 304 is activated to drive the lead screw 306 to rotate, causing the slide block 307 to slide towards the top of the slide groove 305. One end of the support rod 308, connected to the square tube 3091, moves away from the slide groove 305, thereby lifting the auxiliary oil dispensing assembly 309. Then, camera 3094 is activated to observe the oil injection position. If the oil injection position is not ideal, the walking motor 204 can be remotely controlled to rotate forward or backward, while simultaneously controlling the electric cylinder 208 to extend or retract its shaft. This drives the right outrigger 210 to rotate via the transmission pin 207, and the steering linkage 206 drives the left outrigger 202 to rotate synchronously, thus adjusting the oil injection position. The hydraulic cylinder 203 can also adjust the height of the housing 100 off the ground by extending and retracting the hydraulic rod, thereby adjusting the height of the auxiliary oil injection component 309. When a small-range precise adjustment is required, the adjustment motor 303 can be activated. The adjustment motor 303 drives the gear to rotate, and the gear and rack mesh to move the auxiliary oil injection component 309 up and down, ultimately achieving precise oil injection.
