Description

Technical Field

[0001] This invention relates to the field of engine maintenance technology, specifically to a mechanical draining device for preventing engine oil pan leakage during disassembly and assembly. Background Technology

[0002] The engine oil pan, also known as the lower crankcase, is a removable and sealed housing at the bottom of a car engine. It is a key component of the lubrication system and mainly serves to seal the crankcase, store lubricating oil, and prevent impurities from entering. When maintaining the engine, the oil pan usually needs to be disassembled. The process usually involves draining the oil, removing the bolts, and prying open the gasket to separate the oil pan.

[0003] Patent application CN114310786A discloses an oil pan removal device for an automobile engine. The device features a double-handle design for the removal handle. The handle end has a circular flanged through hole for a rotating bolt to pass through. The rotating bolt is a long bolt with a smooth middle section and a threaded end. The device uses double rings and a V-shaped plate to weld together a limiting removal claw, a first sliding removal claw, and a second sliding removal claw. The rotating bolt passes through the circular flanged through hole of the removal handle from one side, and a fixing nut is used to fix the double rings of the limiting removal claw, the first sliding removal claw, and the second sliding removal claw together on the other side. The first and second sliding removal claws slide axially on the rotating bolt.

[0004] During the process of prying open the gasket to separate the oil pan, a small amount of engine oil will still drip out from the top edge of the oil pan. The leaked engine oil will not only contaminate the surface of the engine oil pan, but also affect the surrounding environment of the repair area. It will also increase the potential risks for repair personnel when performing disassembly operations and reduce the efficiency of vehicle maintenance. During the disassembly process, the disassembly device provided by this patent is also easily affected by the leaking engine oil, which will gradually affect the reliability of the device and the efficiency of maintenance over a long period of time.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0031] Example 1

[0032] Please see Figure 1-6 The present invention provides a technical solution: an engine oil pan removal and installation anti-drip mechanical guide device, including a chassis 1, with wheels fixedly connected to both the left and right sides of the chassis 1, oil collection boxes 2 evenly distributed at the four corners of the top of the chassis 1, oil baffles 3 evenly distributed at the four corners of the top of the chassis 1, and an oil pan body 9 set on the top of the chassis 1. Before disassembly, the oil pan body 9 is located at the bottom of the vehicle engine.

[0033] Although most of the engine oil has been drained through the oil drain hole of the oil pan before it is removed, some residual engine oil remains on the inner walls of the engine and the oil pan. During the separation of the oil pan and the engine block, this residual oil will gradually drip out and fall onto the ground near the maintenance area, affecting the cleanliness of the environment and posing a risk of slipping. To address this, a drain bracket 4 is provided on the outer surface of the oil pan block 9 to guide the flow of the dripping engine oil. The drain bracket 4 includes drain slides 41 located on the left and right sides of the chassis 1. Positioning guides 42 are provided on both the front and back of the drain slides 41. The system includes a frame 421 that is slidably connected to the front and back of the drainage slide 41. A transverse drainage plate 422 is fixedly connected to the outer surface of the frame 421. A drainage needle 423 is fixedly connected to the outer surface of the transverse drainage plate 422 to collect and guide the dripping oil and prevent the oil from flowing out along the edge of the mechanism. The positioning guide 42 and the drainage slide 41 are fixed to the left and right sides of the frame 421 by bolts. Heating resistors are embedded inside the drainage slide 41 and the transverse drainage plate 422. The heating resistors are connected to the external control equipment through wires. The outer surfaces of the drainage slide 41, the transverse drainage plate 422, and the drainage needle 423 are covered with an oleophobic layer.

[0034] To guide and collect the oil flowing out of the drain rack 4, two longitudinal collection channels 5 are provided on the top of the chassis 1 and are symmetrically distributed on the top of the chassis 1. The longitudinal collection channels 5 include:

[0035] The longitudinal figure-eight channel 51 includes a longitudinal main body 511 located at the bottom of the drainage frame 4. The longitudinal main body 511 is located at the bottom of the drainage slide 41. A longitudinal support plate 512 is fixedly connected to the bottom of the longitudinal main body 511. The bottom of the left and right sides of the inner wall of the longitudinal main body 511 is inclined towards the center of the longitudinal figure-eight channel 51.

[0036] The longitudinal adjustment channel 52 is slidably connected to the bottom of the longitudinal main body 511. The longitudinal adjustment channel 52 is slidably connected to the back of the longitudinal support plate 512 via a spring. The outer end of the longitudinal adjustment channel 52 is located at the top of the oil collection box 2.

[0037] The longitudinal slide bar 53 includes a longitudinal ball joint seat 531 fixedly connected to the bottom of the longitudinal support plate 512. The bottom of the longitudinal ball joint seat 531 is rotatably connected to a longitudinal ball rod 532. The bottom of the longitudinal ball rod 532 is slidably connected to a sleeve by a spring. The bottom of the sleeve of the longitudinal ball rod 532 is fixedly connected to a pneumatic vibrator 8. The pneumatic vibrator 8 is connected to an external air pump device.

[0038] In order to guide and collect the oil flowing out of the drain rack 4, a transverse collection channel 6 is provided on the top of the chassis 1. There are two transverse collection channels 6, which are symmetrically distributed on the top of the chassis 1. The transverse collection channel 6 is located in front of the longitudinal collection channel 5. The transverse collection channel 6 includes a transverse figure-eight channel 61. The transverse figure-eight channel 61 includes a transverse main body 611 located at the bottom of the drain rack 4. The bottom of the left and right sides of the inner wall of the transverse main body 611 is inclined towards the center of the transverse figure-eight channel 61. A transverse support plate 612 is fixedly connected to the bottom of the transverse main body 611.

[0039] A horizontal adjustment channel 62 is slidably connected to the bottom of the horizontal support plate 612. The horizontal adjustment channel 62 is slidably connected to the back of the horizontal support plate 612 by a spring. The outer end of the horizontal adjustment channel 62 is located at the top of the oil collection box 2, and the horizontal adjustment channel 62 is located at the bottom of the vertical adjustment channel 52.

[0040] A transverse slide bar 63 is provided at the bottom of the transverse support plate 612. The transverse slide bar 63 includes a transverse ball joint seat 631 fixedly connected to the bottom of the transverse support plate 612. A transverse ball joint rod 632 is rotatably connected to the bottom of the transverse ball joint seat 631. A sleeve is slidably connected to the bottom of the transverse ball joint rod 632 through a spring. A pneumatic vibrator 8 is fixedly connected to the bottom of the sleeve of the transverse ball joint rod 632. The pneumatic vibrator 8 is connected to an external air pump device.

[0041] When in use, park the vehicle in the maintenance area, lift the entire vehicle, first install the drain bracket 4 on the outer surface of the oil pan, place the drain slide 41 on the left and right sides of the oil pan, then slide the positioning bracket 42 into the front and back of the drain slide 41, so that the drain slide 41 and the positioning bracket 42 are in contact with the outer surface of the oil pan, and make the top of the drain bracket 4 fit against the top mating surface of the oil pan. Then tighten the bolts of the positioning bracket 42 to fix the drain bracket 4 completely to the oil pan. Then move the entire device to the bottom of the oil pan and start the disassembly operation.

[0042] First, drain the engine oil until no more oil comes out. Then loosen the bolts and remove them. Pry open the joint between the oil pan and the engine body. At this time, some oil seeps out from the pried joint and is guided by the drain slide 41 and the transverse drain plate 422. The oil on the front and back flows to the drain needle 423 and then drips from the tip of the drain needle 423 onto the top of the transverse body 611. After passing through the transverse support plate 612, the oil flows to the oil collection box 2. When the joints on both sides are pried open, the oil is guided by the drain slide 41 onto the top of the longitudinal body 511. After passing through the longitudinal support plate 512, the oil flows to the oil collection box 2, completing the oil collection.

[0043] During this process, the heating resistors inside the drain carriage 41 and the transverse drain plate 422 are energized and generate heat, promoting the flow of engine oil and preventing engine oil from adhering for a long time. At the same time, the pneumatic vibrator 8 promotes the flow of engine oil dripping into the longitudinal collection channel 5 and the transverse collection channel 6 through vibration.

[0044] Example 2

[0045] Please see Figure 1-7 Based on Embodiment 1, the present invention provides a technical solution: Typically, after draining the engine oil, the engine and oil pan are left to stand for a period of time before disassembly. Although this can further reduce oil leakage during disassembly, some oil will still adhere to the bottom of the inner wall of the oil pan, causing accidental leakage when the oil pan is removed and installed. Therefore, to reduce leakage and achieve active oil drainage, an adjustment bracket 7 is provided on the top of the chassis 1. The adjustment bracket 7 includes a hydraulic cylinder bracket 71, which is connected to an external oil pump. A ball joint push rod 72 is slidably connected to the top of the hydraulic cylinder bracket 71. A support plate 73 is provided on the top of the ball joint push rod 72. The support plate 73 includes a plate body 731 rotatably connected to the top of the ball joint push rod 72. Pressure sensors 733 are embedded in the four corners of the plate body 731. The pressure sensors 733 are electrically connected to an external control device via wires. A heating plate 732 and a temperature sensor are embedded inside the plate body 731. The heating plate 732 is electrically connected to an external control device via wires.

[0046] In use, after removing the oil pan, the oil inlet of each cylinder of the hydraulic cylinder frame 71 is adjusted by the external control device, thereby adjusting the stroke of the ball head push rod 72, thus adjusting the posture of the oil pan body 9, so that the oil drain port of the oil pan body 9 faces downward, and an oil pan is placed under the oil pan body 9 to collect the oil. At this time, the oil pan body 9 drives the diversion frame 4 to adjust its posture together. The bottom of the diversion frame 4 squeezes the longitudinal collection channel 5 and the transverse collection channel 6, thereby adaptively adjusting the posture of the longitudinal collection channel 5 and the transverse collection channel 6.

[0047] During this process, the oil dripping from the engine block will fall onto the top of the drain bracket 4 and the oil pan body 9, and the collection process in Embodiment 1 will be carried out. Since the oil pan body 9 is tilted, the oil adhering to the inside of the oil pan body 9 and the oil falling into the inside of the oil pan body 9 will flow to the drain port to discharge the oil. The heating plate 732 is energized and heats up, which heats the oil pan body 9 to a certain extent, promoting the flow of the oil adhering to the inside of the oil pan body 9. At the same time, the pressure sensor 733 provides real-time feedback on the pressure value applied to the four corners of the oil pan body 9, assisting maintenance personnel in adjusting the posture of the oil pan body 9, improving the oil drainage efficiency and the oil drainage effect.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
