[0011] Optionally, a support plate is fixedly fitted on the circumferential surface of the oil pipeline at a position away from the connecting plate, and connecting rods are symmetrically fixed on the lower surfaces of both sides of the support plate, with rollers rotatably mounted on the lower ends of the connecting rods.

[0012] Optionally, the oil leakage prevention mechanism includes a fixed cylinder, an oil guide cylinder, and a sealing component arranged sequentially from top to bottom. The fixed cylinder is vertically fixed on the inner wall of the oil pipeline. A funnel is fixedly connected between the fixed cylinder and the oil guide cylinder, and the fixed cylinder and the oil guide cylinder are in communication. A pressure relief component is provided below the fixed cylinder.

[0013] Optionally, a sliding shaft is provided inside the oil guide cylinder, and a circular stop is fixedly provided at the upper end of the sliding shaft. The diameter of the stop is adapted to the inner diameter of the oil guide cylinder. The lower end of the oil guide cylinder is closed.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. In this utility model, after the oil filling of the oil tank is completed, the stop block no longer has the squeezing force of the lubricating oil. The spring will drive the stop block and the rubber block to reset. The stop block will block the oil guide cylinder, and the rubber block below will block the lower oil outlet of the oil delivery pipe. This can ensure that when changing to another oil tank, the lubricating oil in the oil delivery pipe will not leak onto the surface of the conveyor belt, thus avoiding the waste of lubricating oil and eliminating the need for additional cleaning of the conveyor belt.

[0019] 2. In this utility model, the oil delivery pipe will descend during the process of filling lubricating oil. During the descent, the support plate will move downward. As the descent proceeds, the roller will contact the upper inclined surface of the triangular fixing block and then squeeze the triangular fixing block. The triangular fixing block will drive the sliding frame to approach the oil tank. When the retaining ring on the oil delivery pipe contacts the mouth of the oil tank, the clamps on both sides will clamp the outer surface of the oil tank. Attached Figure Description

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] Please see Figure 1-9 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0032] like Figure 1-6 As shown, a lubricating oil filling device includes a support platform 1 and an inverted U-shaped support frame 2. The support frame 2 spans across the support platform 1. A conveying mechanism is installed on the surface of the support platform 1 to transport the oil tank 5 filled with lubricating oil. Clamping mechanisms 4 are provided on the sides of the two vertical plates of the support frame 2 to limit the oil tank 5. A vertical oil delivery pipe 3 is provided below the support frame 2. A moving component for driving the oil delivery pipe 3 to move up and down is provided on the lower surface of the horizontal plate of the support frame 2. An oil leakage prevention mechanism 6 is provided in the inner cavity of the oil delivery pipe 3 to prevent lubricating oil leakage.

[0033] The upper end of the oil pipeline 3 is connected to a hose 31, and the outer end of the hose 31 is connected to an oil delivery mechanism. The oil delivery mechanism delivers lubricating oil through the hose 31 into the oil pipeline 3, and then fills the oil tank 5, which is moved below the oil pipeline 3, with lubricating oil.

[0034] A retaining ring 32 is fixedly installed on the lower circumferential surface of the oil pipeline 3 near the oil outlet. Several through grooves 321 are opened on the surface of the retaining ring 32.

[0035] The aforementioned oil transportation mechanism is existing technology and will not be drawn or described in detail here.

[0036] like Figure 5As shown in this embodiment, two baffles 11 are symmetrically fixed on the upper surface of the support platform 1. The two baffles 11 are located on both sides of the conveying mechanism, and the distance between the two baffles 11 is adapted to the size of the oil tank 5. The baffles 11 can prevent the oil tank 5 from shaking and tipping over during transportation, thus ensuring the stability of the oil tank 5 during transportation.

[0037] like Figure 5 As shown, in this embodiment, the conveying mechanism includes a conveyor belt 12 and two rollers 121 that rotate with the support platform 1. The conveyor belt 12 is connected to the two rollers 121, and the rotation of the rollers 121 drives the conveyor belt 12 to move. A drive motor 122 with an output shaft fixed to one side of the roller 121 is fixedly installed on the outer side of the support platform 1. The drive motor 122 drives the roller 121 to rotate, thereby causing the conveyor belt 12 to transport the oil tank 5 on the surface.

[0038] like Figure 1 As shown, in this embodiment, the moving component includes a telescopic cylinder 21 symmetrically fixedly disposed on the lower surface of the horizontal plate of the support frame 2. A connecting plate 22 is fixedly disposed on the lower end face of the piston rod of the telescopic cylinder 21. The connecting plate 22 is fixedly sleeved on the circumferential surface of the oil pipeline 3. The telescopic cylinder 21 drives the oil pipeline 3 to move up and down.

[0039] like Figure 2-4 As shown, in this embodiment, the clamping mechanism 4 includes a support rod 43 and a sliding frame 45. The sliding frame 45 is slidably sleeved on the surface of the support rod 43, and the support rod 43 is fixedly installed on the outer side of the vertical plate of the support frame 2.

[0040] A spring 431 is fixedly installed on the outer end face of the support rod 43, and the spring 431 is fixed to the sliding frame 45;

[0041] A triangular fixing block 44 is fixedly provided on the upper surface of the sliding frame 45;

[0042] A clamping plate is fixedly provided on the outer end face of the sliding frame 45. The clamping plate is adapted to the outer surface of the oil tank 5. The clamping plate clamps and limits the oil tank 5 by the relative movement of the two sliding frames 45, so as to prevent the oil tank 5 from shaking during the oil filling process.

[0043] like Figure 4 As shown, in this embodiment, a support plate 41 is fixedly sleeved on the circumferential surface of the oil pipeline 3 at a position away from the connecting plate 22. Connecting rods 42 are symmetrically fixed on the lower surfaces of both sides of the support plate 41, and rollers 421 are rotatably mounted on the lower ends of the connecting rods 42.

[0044] Specifically, during the process of filling lubricating oil, the oil pipe 3 will descend, which will cause the support plate 41 to move downward. As the descent continues, the roller 421 will contact the upper inclined surface of the triangular fixing block 44 and then squeeze the triangular fixing block 44. The triangular fixing block 44 will drive the sliding frame 45 to approach the oil tank 5. When the retaining ring 32 on the oil pipe 3 contacts the bottle mouth of the oil tank 5, the clamping plates 451 on both sides will clamp the outer surface of the oil tank 5. At this time, the retaining ring 32 can also fix the oil tank 5.

[0045] Furthermore, the diameter of the oil delivery pipe 3 is smaller than the diameter of the bottle opening of the oil tank 5. Therefore, after the lower end of the oil delivery pipe 3 has descended, a portion of the oil will enter the oil tank 5. The through groove 321 on the baffle is used to allow the gas inside the oil tank 5 to flow out during the oil filling process, ensuring that the gas pressure inside the oil tank 5 is stable.

[0046] like Figure 7-8 As shown, in this embodiment, the oil leakage prevention mechanism 6 includes a fixed cylinder 61, an oil guide cylinder 62 and a sealing component 631 arranged sequentially from top to bottom. The fixed cylinder 61 is vertically fixedly installed on the inner wall of the oil pipeline 3. A funnel is fixedly connected between the fixed cylinder 61 and the oil guide cylinder 62, and the fixed cylinder 61 and the oil guide cylinder 62 are in communication.

[0047] A sliding shaft 63 is provided inside the oil guide cylinder 62, and a circular stop 632 is fixedly provided at the upper end of the sliding shaft 63. The diameter of the stop 632 is adapted to the inner cavity diameter of the oil guide cylinder 62.

[0048] The lower end of the oil guide cylinder 62 is in a closed state, and the sliding shaft 63 passes through the lower end face of the oil guide cylinder 62 and is in sliding fit.

[0049] Several oil outlet grooves 621 are circumferentially formed on the circumferential surface near the lower end of the oil guide cylinder 62;

[0050] A spring 622, which is sleeved on the circumferential surface of the sliding shaft 63, is fixedly connected between the stop block 632 and the inner bottom surface of the oil guide cylinder 62.

[0051] like Figure 8 As shown, in this embodiment, the sealing component 631 includes a circular rubber block. The diameter of the rubber block is adapted to the diameter of the oil pipeline 3, which can seal the lower oil outlet of the oil pipeline 3. The rubber block is fixed to the lower end face of the sliding shaft 63.

[0052] Specifically, when the oil tank 5 is filled with oil, the oil conveying mechanism introduces lubricating oil into the oil conveying pipe 3. The lubricating oil will squeeze the stop block 632, causing the stop block 632 to drive the sliding shaft 63 to move downward. The spring 622 is compressed. As the stop block 632 descends, the oil guide cylinder 62 will communicate with the lower oil cavity of the oil conveying pipe 3 through the oil outlet groove 621. At this time, the rubber block has descended to the outside of the oil conveying pipe 3, and the lubricating oil can smoothly enter the oil tank 5.

[0053] After the oil filling tank 5 is finished, the stop block 632 is no longer under the pressure of the lubricating oil. The spring 622 will drive the stop block 632 and the rubber block to reset. The stop block 632 will block the oil guide cylinder 62, and the rubber block below will block the lower oil outlet of the oil delivery pipe 3. This ensures that when changing to another oil filling tank 5, the lubricating oil in the oil delivery pipe 3 will not leak onto the surface of the conveyor belt 12, thus avoiding the waste of lubricating oil and eliminating the need for additional cleaning of the conveyor belt 12.

[0054] like Figure 8-9 As shown, in this embodiment, in order to ensure that the air pressure in the inner cavity of the oil pipe 3 between the rubber block and the fixed cylinder 61 is stable during the reset process of the rubber block and the stop block 632, a pressure relief component can be set below the fixed cylinder 61.

[0055] The pressure relief assembly includes a support ring 65 and several circumferentially arranged guide shafts 661. The support ring 65 has a horizontal ring and a vertical ring. The guide shafts 661 pass through the horizontal ring of the support ring 65 and are slidably engaged. The vertical ring of the support ring 65 is fixedly mounted on the lower end face of the fixed cylinder 61. The lower end of the guide shaft 661 is threaded with a nut 663 to prevent the guide shaft 661 from detaching from the support ring 65.

[0056] The lower surface of the inner cavity of the fixed cylinder 61 is provided with a number of countersunk holes 611, the same as the number of countersunk holes 611 as the guide shaft 661. A circular pressure relief plate 66 is fixedly installed at the upper end of the guide shaft 661. The pressure relief plate 66 is slidably installed in the upper hole of the countersunk hole 611. The diameter of the guide shaft 661 is smaller than the diameter of the lower hole of the countersunk hole 611. A spring 662, which is sleeved on the surface of the guide shaft 661, is fixedly connected between the pressure relief plate 66 and the ring body of the support ring 65 in the horizontal direction.

[0057] Specifically, when the rubber block and the stop block 632 are reset, the rubber block returns to the oil supply pipe 3, and the stop block 632 blocks the oil outlet groove 621. At this time, the rubber block and the stop block 632 will continue to rise a certain distance until the second spring 622 returns to its original position. During the process of the rubber block continuing to rise, the internal air pressure of the oil supply pipe 3 will push the pressure relief plate 66 to rise, and the third spring 662 will be stretched until the pressure in the inner cavity of the oil supply pipe 3 between the rubber block and the fixed cylinder 61 is released. Then, the third spring 662 will drive the pressure relief plate 66 to reset.
