Description

Technical Field

[0001] This invention relates to the field of vehicle pretreatment technology, specifically to a degreasing liquid removal device for vehicle pretreatment. Background Technology

[0002] Pre-treatment degreasing and oil removal for vehicle bodies involves removing oil and dirt from the vehicle surface using chemical and physical methods. The degreasing solution mainly consists of alkali and surfactants. It utilizes a saponification reaction (ester hydrolysis), where fatty acids react with alkali to produce fatty acid salts and water. Simultaneously, the surfactants chemically react with the oil on the vehicle body, dissolving it in water. Heating is then used to break up the emulsion, separating the oil and draining it from the degreasing tank. Currently, the main methods for degreasing and oil removal on the front of the vehicle body are spray degreasing and immersion degreasing. 1. Degreasing by spraying: This method mainly uses a high-pressure spraying device to spray degreasing agent onto the car body. However, this method has certain drawbacks. When the temperature of the degreasing agent is too low and there is an air leak in the pump body seal, more foam will be sprayed onto the car body, which will reduce the effectiveness of removing oil stains from the car body surface.

[0003] 2. Immersion degreasing: Traditional immersion methods require immersing the entire car body in a degreasing agent solution and using equipment such as ultrasound to remove oil stains from the car body. However, this method also has certain drawbacks. Due to the different degrees of oil solidification on the car body surface, the cleaning power is insufficient with low or no mechanical pressure, which will prolong the immersion time and increase energy consumption costs.

[0004] In view of this, a degreasing liquid removal device for vehicle body pretreatment was designed to solve the above problems. Summary of the Invention

[0010] In a preferred embodiment, the present invention may be further configured such that: the inner shell cleansing mechanism further includes a load-bearing beam movably installed in two tracks, a waterproof hydraulic component fixedly installed in the middle of the load-bearing beam, a clamp installed at the top of the hydraulic rod inside the waterproof hydraulic component, and two inclined arms movably installed at both ends of the clamp; The top plate of the load-bearing beam has a groove for constraining two sets of first outer clamps, and the bottom plate of the load-bearing beam has a groove for constraining two sets of first outer clamps and two sets of inner side fastening components. The two limiting frames are adapted to penetrate into two grooves in the bottom plate of the load-bearing beam, and the bottom end of the limiting frame is attached to the bottom of the inner cavity of the washing tank.

[0012] In a preferred embodiment, the present invention may be further configured such that the internal fitting assembly further includes five internal clamps, one of which is movably mounted on the pressure measuring end, two other internal clamps are movably mounted on two ends of the inclined pressure end, and the remaining two internal clamps are movably mounted on two ends of the top pressure end.

[0013] In a preferred embodiment, the present invention may be further configured such that the inner side fastening assembly includes a second column, a second top cover fixedly installed on the top of the second column, a second spring disposed inside the second column, a second sliding column movably installed between the second column and the second top cover, a second sealing plate installed outside the second sliding column, and a drawer plate installed outside the second column.

[0014] In a preferred embodiment, the present invention may be further configured such that: the elastic support is composed of a telescopic main tube, a telescopic secondary rod and a built-in compression spring, and the end of the telescopic secondary rod that penetrates into the inner cavity of the telescopic main tube is provided with a leak-proof plug.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention provides a cleaning mechanism by symmetrically distributing two tracks on the inner wall of a washing tank and laterally sliding an inner shell cleaning mechanism between the two tracks. When the hanger suspends the entire vehicle body into the washing tank until the body is completely submerged in the degreasing solution, the inner shell cleaning mechanism adapts to the inner side of the vehicle body and provides an inner cleaning platform. Simultaneously, an outer shell cleaning mechanism is provided on the outside of the vehicle body to provide an outer cleaning platform for the outer wall of the vehicle body. As the inner and outer cleaning platforms are pulled and vibrate at high frequency in the horizontal direction, the inner and outer walls of the vehicle body can be forcibly degreased under strong mechanical pressure, thereby improving the efficiency of degreasing and oil removal of the vehicle body.

[0017] 2. This invention involves the symmetrical installation of two sets of internal positioning components within the load-bearing beam. As the waterproof hydraulic components operate and control the two sets of internal positioning components to expand outward along the inner side of the vehicle shell, the two sets of internal positioning components can cooperate with multiple evenly distributed internal clamps to stretch the internal ribs and internal brush rollers until the internal ribs and internal brush rollers are fitted onto the irregular grooves or protrusions on the inner side of the vehicle shell. Meanwhile, the external brush roller is forcibly tightened by two sets of external edge tightening components. Ultimately, the external brush roller will fit against the irregular grooves or protrusions on the outer side of the vehicle shell, thereby ensuring that the oil stains that have solidified in the crevices of the vehicle shell are efficiently removed.

[0018] 3. In this invention, the degreasing assist mechanism is directly controlled by hydraulic components. Since the car body has a streamlined curved surface, in order to improve the perfect fit of the car body cleaning mechanism to the streamlined curved surface of the car body, the hydraulic components are directly operated to drive the degreasing assist mechanism to perform relative lifting and lowering activities. At this time, the car body cleaning mechanism suspended by the degreasing assist mechanism can prevent sagging, and at the same time, it can perform non-destructive cleaning treatment on the streamlined curved surface of the car body.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a degreasing liquid oil removal device for vehicle body pretreatment.

[0024] Example 1: Combination Figures 1 to 9 As shown, the present invention provides a degreasing liquid degreasing device for vehicle body pretreatment, including a ground-mounted cleaning and degreasing mechanism 100, a degreasing assist mechanism 200 disposed on the cleaning and degreasing mechanism 100, an inner shell cleaning mechanism 400 disposed within the cleaning and degreasing mechanism 100, and an outer shell cleaning mechanism 300 disposed on the degreasing assist mechanism 200, with the outer shell cleaning mechanism 300 located directly above the inner shell cleaning mechanism 400. The cleaning and degreasing mechanism 100 is used to hold the degreasing solution and provides a free lifting platform for the degreasing assist mechanism 200, while providing a horizontal brushing platform for the inner shell cleaning mechanism 400. The degreasing assist mechanism 200 is used to suspend the outer shell cleaning mechanism 300 and adapt to the streamlined curved surface of the outer side of the vehicle body. The outer shell cleaning mechanism 300 is used to provide an outer cleaning platform for the outer side of the vehicle body, and the inner shell cleaning mechanism 400 is used to provide an inner cleaning platform for the inner side of the vehicle body.

[0025] The outer shell facial cleansing mechanism 300 includes two sets of outer side fastening components 310, an outer rib 320 disposed between the two sets of outer side fastening components 310, an outer brush roller 330 disposed outside the outer rib 320, two first outer clamps 350 installed at both ends of the outer rib 320, positioning bolts 360 installed inside the first outer clamps 350, a plurality of second outer clamps 340 installed outside the outer rib 320 and located between the two first outer clamps 350, and reinforcing ribs 370 connected inside the two first outer clamps 350 and penetrating into the plurality of second outer clamps 340; The reinforcing rib 370 is used to enhance the structural strength of the outward expansion of the outer brush roller 330 and to provide an external cleaning platform for the outer side of the car body; The inner shell facial cleansing mechanism 400 includes a load-bearing beam 410, two sets of inner side clamping components 460 disposed inside the two sets of first outer clamps 350, an inner rib 470 disposed between the two sets of inner side clamping components 460, an inner brush roller 480 disposed outside the inner rib 470, two sets of shell-mounted matching components 450 disposed on the inner rib 470 and located inside the inner brush roller 480, a waterproof hydraulic component 420 fixedly installed in the middle of the load-bearing beam 410, a clamp 430 installed at the top of the hydraulic sub-rod inside the waterproof hydraulic component 420, and two inclined arms 440 movably installed at both ends of the clamp 430. The top plate of the load-bearing beam 410 has a groove for restraining two sets of first outer clamps 350, and the bottom plate of the load-bearing beam 410 has a groove for restraining two sets of first outer clamps 350 and two sets of inner side fastening components 460. The outer brush roller 330 and the inner brush roller 480 are made of multiple layers of thickened cotton brushes; The housing assembly 450 includes a vertical frame 451, a slide bar 452 inserted into the bottom of the vertical frame 451, a clamping plate 453 fixedly installed at the bottom of the vertical frame 451 and movably installed on the other end of the inclined arm 440, three elastic support members 454 fixedly installed inside the vertical frame 451, a pressure measuring end 457 movably installed on the side of the vertical frame 451 and placed in the bottom slide plate, an inclined pressure end 456 movably installed on the side of the vertical frame 451 and placed in the middle slide plate, and a top pressure end 455 movably installed in the top slide plate of the vertical frame 451. The housing fitting assembly 450 also includes five inner clamps 458. One inner clamp 458 is movably mounted on the pressure measuring end 457, two other inner clamps 458 are movably mounted on two ends of the inclined pressure end 456, and the remaining two inner clamps 458 are movably mounted on two ends of the top pressure end 455. The five inner clamps 458 are used to adjust the lateral bending of the inner rib 470 and to adapt and fit the inner side of the car body. Two sets of in-shell fitting components 450 are used to stretch the inner brush roller 480 to fit the inner side of the car shell, and the inner brush roller 480 is used to provide an inner cleaning platform for the inner side of the car shell. The inner and outer cleaning platforms are used to enhance the mechanical pressure on the inner and outer sides of the car shell and improve the efficiency of cleaning oil stains.

[0026] The tightness of the reinforcing rib 370 is adjusted by loosening the two positioning bolts 360. When the reinforcing rib 370 is stretched outward and the outer brush roller 330 and the outer rib rod 320 are raised upward, the two positioning bolts 360 can be tightened. The outer rib rod 320 with the two sets of outer side fastening components 310 fixed can form a U-shaped structure with the port facing downward. When the hoist 211 lifts the entire car body directly above the cleaning and degreasing mechanism 100 until the lifted car body is submerged in the degreasing solution inside the cleaning and degreasing mechanism 100, the two sets of expanded shell-mounted matching components 450 can expand the inner brush roller 480 outward until the expanded inner brush roller 480 fits and adheres to the inner side of the car body. At this time, the inner brush roller 480 and the two sets of shell-mounted matching components 450 can provide an inner cleaning platform for the inner side of the car body while also stabilizing and supporting the car body. The car body will be located in the center of the degreasing solution. As the outer brush roller 330 descends along the outer side of the car body until the outer brush roller 330 is pressed and adheres to the outer side of the car body, the outer brush roller 330 can provide an outer cleaning platform for the outer side of the car body, thereby ensuring that the transverse and vibrating inner cleaning platform and the outer cleaning platform thoroughly and efficiently remove oil from the car body.

[0027] Example 2: Combination Figures 1 to 3As shown, based on Embodiment 1, the cleaning and degreasing mechanism 100 includes a water washing tank 110, two tracks 120 fixedly installed on the inner wall of the water washing tank 110, two sets of clamps 130 fixedly installed on the outer side of the water washing tank 110, a hydraulic component 140 fixedly installed inside the two sets of clamps 130, and a suspension plate 150 installed at the top of the hydraulic rod inside the hydraulic component 140. Two tracks 120 are used to provide a free sliding support platform for the inner shell cleaning mechanism 400, and the outer shell cleaning mechanism 300 and the inner shell cleaning mechanism 400 after high-frequency vibration can move stably along the two tracks 120 to apply forced degreasing pressure to the inner and outer sides of the shell.

[0028] Preferably, the two rails 120 are fixedly installed on the side wall of the water washing tank 110, and the two ends of the load-bearing beam 410 are movably installed in the two rails 120. When the hydraulic component 140 is running, the degreasing assist mechanism 200 driven by its internal hydraulic rod can adapt and press the suspended outer shell cleaning mechanism 300 onto the outer side wall of the car body, and the load-bearing beam 410 is calibrated and constrained by the two limit frames 280. Finally, the outer shell cleaning mechanism 300 and the inner shell cleaning mechanism 400 can clean the inner and outer sides of the car body at the same time.

[0029] Example 3: Combination Figures 3 to 7 As shown, based on Embodiment 1, the degreasing assist mechanism 200 includes a power supply component 210 installed at the other end of the suspension plate 150; The power supply assembly 210 includes a lifting device 211, an eccentric wheel 212 movably installed inside the lifting device 211, a housing 213 fixedly installed on the top of the lifting device 211, a motor 214 fixedly installed inside the housing 213, a drive wheel 215 fixedly installed at the bottom of the drive shaft inside the motor 214, and a transmission belt 216 that is connected to the drive wheel 215 and the eccentric wheel 212. The degreasing assist mechanism 200 also includes a slider 240 movably installed in the hanger 211, an adjustable suspension 250 installed in the slider 240, two supports 260 movably installed in the inclined grooves at both ends, a fixed end 270 installed at the bottom of the support 260, and a limiting frame 280 provided outside the fixed end 270. Two limiting brackets 280 are adapted to penetrate into two grooves in the bottom plate of the load-bearing beam 410, and the bottom of the limiting brackets 280 is attached to the bottom of the inner cavity of the washing tank 110.

[0030] Preferably, the lifting device 211 has an overall L-shaped structure, and the housing 213 is fixed to two studs on the top of the lifting device 211 by nuts. The drive wheel 215 and the top end of the eccentric wheel 212 can be replaced by gears, and the corresponding transmission belt 216 needs to be matched with two gears to be set as a chain. When the motor 214 starts, the pull rod 220 and the traction rod 230, which are driven by gears and chains, will extend more stably and regularly, thereby improving the cleaning efficiency of the outer brush roller 330 and the inner brush roller 480 on the inside and outside of the car body.

[0031] Example 3: Combination Figure 5 and Figure 8 As shown, based on Embodiment 1, the outer side fastening assembly 310 includes a first column 311 installed in the fixed distance end 270, a first top cover 312 fixedly installed on the top of the first column 311, a first spring 313 disposed inside the first column 311, a first sliding column 314 movably installed between the first column 311 and the first top cover 312 and placed horizontally, and a first sealing plate 315 installed outside the first sliding column 314, and the first sealing plate 315 is adapted to penetrate into the vertical groove of the inner wall of the first column 311 and the first top cover 312; Two sets of outer edge tightening components 310 are used to forcibly tighten the outer rib 320, and together with the reinforcing rib 370, they enhance the structure of the outer rib 320 to improve the perfect fit of the outer brush roller 330 to the outer side of the car body.

[0032] Preferably, the fixed end 270 is fixed in the middle of the first column 311. As the support frame 260 applies downward pressure, the fixed end 270 installed at the bottom of the support frame 260 will be pressed and push the outer side tightening assembly 310 to continuously descend into the slide groove of the bottom end plate of the load-bearing beam 410. The outer rib rod 320 set between the two first slide columns 314 can carry the outer brush roller 330 to adapt and fit the outer side of the car body. Finally, the outer brush roller 330 can fully fit the streamlined curved surface of the outer side of the car body.

[0033] The inner side fastening assembly 460 includes a second column 461, a second top cover 462 fixedly installed on the top of the second column 461, a second spring 463 disposed inside the second column 461, a second slide column 464 movably installed between the second column 461 and the second top cover 462, a second sealing plate 465 installed outside the second slide column 464, and a drawer plate 466 installed outside the second column 461. The elastic support 454 is composed of a telescopic main tube, a telescopic secondary rod, and a built-in compression spring, and the end of the telescopic secondary rod that penetrates into the inner cavity of the telescopic main tube is provided with a leak-proof plug.

[0034] Preferably, the drawer plate 466 is fixedly installed on the second column 461, and the bottom end of the second column 461 is movably installed inside the load-bearing beam 410, and the drawer plate 466 is adapted to fit against the bottom end plate of the load-bearing beam 410 to provide a stabilizing platform for the horizontal lateral movement of the second column 461. Two sets of inner side tightening components 460 are used to provide downward support for the two ends of the inner rib 470 extending into the inner side of the car body, and cooperate with the two sets of inner housing matching components 450 to stretch the inner rib 470 and the inner brush roller 480. Finally, the stretched inner brush roller 480 can be adapted and fitted to the irregular area inside the car body.

[0035] The working principle and usage process of the present invention: After the lifting device 211 suspends the car body directly above the water washing tank 110, the lifting device 211 is used to immerse the car body into the solution inside the water washing tank 110 until the car body is fitted to be mounted on the outside of the inner shell cleaning mechanism 400. As the vehicle body descends, the waterproof hydraulic component 420 is operated until its internal hydraulic rod rises. The clamp 430 installed at the top of the hydraulic rod inside the waterproof hydraulic component 420 pulls the two inclined arms 440 to retract. At this time, the two sets of housing matching components 450 retract relative to each other along the groove of the top plate of the load-bearing beam 410. As the two sets of housing matching components 450 continue to retract, the combined inner rib 470 and inner brush roller 480 can be reduced until the reduced inner brush roller 480 is completely attached to the inner wall of the vehicle body. When the height of the vehicle body descent is constant, the waterproof hydraulic component 420 can be operated again until its internal hydraulic rod descends. The two inclined arms 440, which are pressed downward by the clamp 430, will push the two sets of housing matching components 450 to expand outward until the inner rib 470 and inner brush roller 480 are adapted to the structure of the inner side of the vehicle body. At this time, the inner brush roller 480 will provide an effective inner cleaning platform for the inner wall of the vehicle body. Next, the hydraulic component 140 is operated again. As the hydraulic subrod inside the hydraulic component 140 descends, the suspension plate 150 installed at the top of the hydraulic subrod will drive the power supply component 210 to descend as a whole. The slider 240 and the adjustable suspension 250 installed in the bottom groove of the hanger 211 will press down on the two supports 260 until the two supports 260 are centered and close together under the constraint of the load-bearing beam 410. The two limit frames 280 limit the lateral movement of the two fixed ends 270. At this time, the two sets of outer side tightening components 310 installed in the two fixed ends 270 will continue to descend along the groove of the bottom end plate of the load-bearing beam 410. Finally, the two sets of outer side tightening components 310 will press the outer rib rod 320 and the outer brush roller 330 onto the car body shell. At this time, the outer brush roller 330 will provide an effective external cleaning platform for the car body shell. When the motor 214 starts and runs, the internal transmission shaft of the motor 214 will work with the drive wheel 215 to drive the transmission belt 216. The eccentric wheel 212 held by the hanger 211 will drive the pull rod 220 to rotate eccentrically. Finally, the traction rod 230 will drive the slider 240 and the adjustable suspension 250 to vibrate at high frequency in the horizontal direction. After the degreasing assist mechanism 200 vibrates as a whole, the load-bearing beam 410 constrained by the two limit frames 280 will also vibrate along the inner side of the two tracks 120. At this time, the inner cleaning platform and the outer cleaning platform can work with the cleaning solution to perform efficient degreasing and oil removal on the vehicle body surface.

[0036] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
