Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body pre-treatment, in particular to a degreasing liquid deoiling device for vehicle body pre-treatment. Background Art

[0002] Degreasing and oil removal is a pre-treatment process for vehicle bodies that removes oil stains from the vehicle's surface through chemical and physical methods. The degreasing solution primarily consists of alkali and surfactants, utilizing saponification (ester hydrolysis), where fatty acids react with alkali to form fatty acid salts and water. The surfactants also chemically dissolve the oil on the vehicle body in water, and heating the emulsion to separate the oil and drain it out of the degreasing tank. The existing front degreasing and oil removal of vehicle bodies mainly adopts two methods: spray degreasing or immersion degreasing: 1. Spray degreasing: It mainly uses a high-pressure spray device to spray the degreaser onto the car body. However, this method has certain defects. When the degreaser temperature is too low and the pump seal leaks, the foam sprayed onto the car body will increase, which will lead to a decrease in the oil removal effect on the car body surface.

[0003] 2. Immersion degreasing: The traditional immersion method requires the entire vehicle body to be immersed in a degreaser solution, and ultrasonic equipment and other equipment are used in conjunction with solution immersion to remove the oil stains on the vehicle body. However, this method also has certain defects. Due to the different degrees of oil solidification on the surface of the vehicle body, the cleaning power of low mechanical pressure or no mechanical pressure is insufficient, which will extend the immersion time and increase energy consumption costs.

[0004] In view of this, a degreasing liquid degreasing device for vehicle body pre-treatment is designed to solve the above problems. Summary of the Invention

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. The present invention provides two symmetrically distributed tracks on the inner wall of the water washing tank, and provides an inner shell cleaning mechanism that can slide laterally between the two tracks.

[0018] 3. The degreasing assisting mechanism in the present invention is directly controlled by hydraulic components. Since the vehicle shell has a streamlined surface, in order to improve the perfect adaptation of the shell cleaning mechanism to the streamlined surface of the vehicle shell, the hydraulic components are directly operated to push the degreasing assisting mechanism to perform relative lifting activities. At this time, the shell cleaning mechanism suspended by the degreasing assisting mechanism can prevent sagging, and at the same time, the streamlined surface of the vehicle shell can be cleaned non-destructively.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0023] A degreasing device for degreasing liquid for vehicle body pre-treatment provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] Example 1: Combine Figures 1 to 9 As shown, the present invention provides a degreasing liquid deoiling device for vehicle body pre-treatment, comprising a ground-mounted cleaning and degreasing mechanism 100, a degreasing auxiliary mechanism 200 arranged on the cleaning and degreasing mechanism 100, an inner shell cleaning mechanism 400 arranged in the cleaning and degreasing mechanism 100, and an outer shell cleaning mechanism 300 arranged on the degreasing auxiliary mechanism 200, and the outer shell cleaning mechanism 300 is located directly above the inner shell cleaning mechanism 400. The cleaning and degreasing mechanism 100 is used to hold the degreasing solution and provide a free lifting platform for the degreasing auxiliary mechanism 200, while providing a horizontal brush platform for the inner shell cleaning mechanism 400. The degreasing auxiliary mechanism 200 is used to suspend the outer shell cleaning mechanism 300 and adapt to the streamlined curved surface on the outside of the vehicle shell. The outer shell cleaning mechanism 300 is used to provide an outer cleaning platform for the outside of the vehicle shell, and the inner shell cleaning mechanism 400 is used to provide an inner cleaning platform for the inside of the vehicle shell.

[0025] The outer shell cleaning mechanism 300 includes two sets of outer edge tightening assemblies 310, an outer rib 320 disposed between the two sets of outer edge tightening assemblies 310, an outer brush roller 330 disposed outside the outer rib 320, two first outer clamps 350 mounted on both ends of the outer rib 320, a positioning bolt 360 mounted in the first outer clamp 350, a plurality of second outer clamps 340 mounted outside the outer rib 320 and located between the two first outer clamps 350, and a reinforcing rib 370 connected to the two first outer clamps 350 and extending through the plurality of second outer clamps 340. The reinforcing ribs 370 are used to enhance the structural strength of the outer brush roller 330 and provide an outer cleaning platform for the outside of the vehicle shell; The inner shell cleaning mechanism 400 includes a load-bearing beam 410, two sets of inner side tightening assemblies 460 arranged inside the two sets of first outer clamps 350, an inner rib 470 arranged between the two sets of inner side tightening assemblies 460, an inner brush roller 480 arranged outside the inner rib 470, two sets of inner shell coordination assemblies 450 arranged 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 clamping seat 430 installed at the top end of the hydraulic sub-rod in the waterproof hydraulic component 420, and two inclined arms 440 movably mounted at both ends of the clamping seat 430; A sliding groove is defined in the top plate of the load-bearing beam 410 to be constrained by the two sets of first outer clamps 350 , and a sliding groove is defined in the bottom plate of the load-bearing beam 410 to be constrained by the two sets of first outer clamps 350 and the two sets of inner side tightening assemblies 460 . The outer brush roller 330 and the inner brush roller 480 are made of multiple layers of thickened cotton brushes; The in-shell coordination assembly 450 includes a vertical frame 451, a slide rod 452 inserted into the bottom end of the vertical frame 451, a clamping plate 453 fixedly mounted on the bottom end of the vertical frame 451, and the clamping plate 453 is movably mounted on the other end of the oblique arm 440, three elastic support members 454 fixedly mounted in the vertical frame 451, a pressure measuring terminal 457 movably mounted on the side of the vertical frame 451 and in the bottom slide, an oblique pressure terminal 456 movably mounted on the side of the vertical frame 451 and in the center slide, and a top pressure terminal 455 movably mounted in the top slide of the vertical frame 451; The inner shell coordination assembly 450 further includes five inner clamps 458, one of which is movably mounted on the pressure measuring terminal 457, two other inner clamps 458 are movably mounted on two ends of the oblique pressure terminal 456, and the remaining two inner clamps 458 are movably mounted on two ends of the top pressure terminal 455. The five inner clamps 458 are used to adjust the lateral bending amplitude of the inner rib 470 and adapt the inner shell to the inner side of the vehicle body. The two sets of in-shell coordination components 450 are used to stretch the inner brush roller 480 to adapt to the inner side of the vehicle shell, and the inner brush roller 480 is used to provide an inner cleaning platform for the inner side of the vehicle shell, and the inner and outer cleaning platforms are used to enhance the mechanical pressure on the inner and outer sides of the vehicle shell and improve the efficiency of cleaning oil stains.

[0026] The tightness of the reinforcing ribs 370 can be adjusted by loosening the two positioning bolts 360. When the reinforcing ribs 370 are 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, and the outer rib rod 320 fixed by the two sets of outer side tightening assemblies 310 can form a U-shaped structure with the end facing downward. When the hoist 211 lifts the entire car shell toward the top of the cleaning and degreasing mechanism 100 until the lifted car shell is immersed in the degreasing solution in the cleaning and degreasing mechanism 100, the two sets of expanded in-shell coordination components 450 can expand the inner brush roller 480 outward until the expanded inner brush roller 480 fits well with the inner side of the car shell. At this time, the inner brush roller 480 and the two sets of in-shell coordination components 450 can provide an inner cleaning platform for the inside of the car shell while providing stability and support for the car shell. The car shell will be located in the center of the degreasing solution. As the outer brush roller 330 descends along the outside of the car shell until the outer brush roller 330 is pressed and fits against the outside of the car shell, the outer brush roller 330 can provide an outer cleaning platform for the outside of the car shell, thereby ensuring that the laterally moving and vibrating inner cleaning platform and outer cleaning platform can comprehensively and efficiently remove oil from the car shell.

[0027] Example 2: Combine Figures 1 to 3As shown, based on Example 1, the cleaning and degreasing mechanism 100 includes a water washing tank 110, two rails 120 fixedly mounted on the inner wall of the water washing tank 110, two sets of clamps 130 fixedly mounted on the outside of the water washing tank 110, a hydraulic component 140 fixedly mounted inside the two sets of clamps 130, and a suspension plate 150 mounted on the top of the hydraulic sub-rod in the hydraulic component 140; The two tracks 120 are used to provide a freely 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 stably move laterally along the two tracks 120 to apply forced oil removal pressure to the inner and outer sides of the vehicle body.

[0028] Preferably, the two tracks 120 are fixedly mounted on the side walls of the washing tank 110, and the two ends of the load-bearing beam 410 are movably mounted in the two tracks 120. When the hydraulic component 140 is running, the degreasing auxiliary mechanism 200 pushed by the internal hydraulic sub-rod can adapt and press the suspended outer shell cleaning mechanism 300 onto the outer wall of the vehicle shell, and calibrate the load-bearing beam 410 with the two limit frames 280. Finally, the outer shell cleaning mechanism 300 and the inner shell cleaning mechanism 400 can clean the inside and outside of the vehicle shell at the same time.

[0029] Example 3: Combine Figures 3 to 7 As shown, based on embodiment 1, the degreasing auxiliary mechanism 200 includes an energy supply component 210 installed at the other end of the suspension plate 150; The energy supply assembly 210 includes a sling 211, an eccentric disc 212 movably mounted within the sling 211, a chassis 213 fixedly mounted on the top of the sling 211, a motor 214 fixedly mounted within the chassis 213, a drive wheel 215 fixedly mounted at the bottom end of a transmission shaft within the motor 214, and a transmission belt 216 connected between the drive wheel 215 and the eccentric disc 212. The degreasing auxiliary mechanism 200 further includes a slider 240 movably mounted in the sling 211, a distance-adjusting suspension 250 mounted in the slider 240, two supports 260 movably mounted in the chute at both ends, a distance-fixing end 270 mounted at the bottom end of the supports 260, and a limit frame 280 disposed outside the distance-fixing end 270. The two limiting frames 280 are adapted to penetrate into the two sliding grooves of the bottom plate of the load-bearing beam 410 , and the bottom ends of the limiting frames 280 are attached to the bottom of the inner cavity of the washing tank 110 .

[0030] Preferably, the sling 211 is L-shaped as a whole, and the chassis 213 is fixed to the two studs on the top of the sling 211 by nuts. The driving wheel 215 and the end of the top of the eccentric wheel disc 212 can be replaced by gears, and the corresponding transmission belt 216 needs to be configured as a chain with the two gears. When the motor 214 is started, the pull rod 220 and the traction rod 230 driven by the gear and chain 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 vehicle shell.

[0031] Example 3: Combine Figure 5 and Figure 8 As shown, based on Example 1, the outer side tightening assembly 310 includes a first column 311 installed in the distance end head 270, a first top cover 312 fixedly installed on the top of the first column 311, a first spring 313 arranged inside the first column 311, a first sliding column 314 movably installed and horizontally disposed between the first column 311 and the first top cover 312, and a first sealing plate 315 installed outside the first sliding column 314, and the first sealing plate 315 is adapted to penetrate the vertical grooves on the inner walls of the first column 311 and the first top cover 312; The two sets of outer side tightening components 310 are used to forcibly tighten the outer rib 320 and cooperate with the reinforcing ribs 370 to strengthen the structure of the outer rib 320 to improve the perfect adaptation of the outer brush roller 330 to the outer side of the vehicle shell.

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

[0033] The inner side tightening assembly 460 includes a second column 461, a second top cover 462 fixedly mounted on the top of the second column 461, a second spring 463 disposed inside the second column 461, a second sliding column 464 movably mounted between the second column 461 and the second top cover 462, a second sealing plate 465 mounted on the outside of the second sliding column 464, and a drawer plate 466 mounted on the outside of the second column 461. The elastic support member 454 is composed of a telescopic mother tube, a telescopic sub-rod and a built-in compression spring, and an anti-seepage plug is provided at the end of the telescopic sub-rod that passes through the inner cavity of the telescopic mother tube.

[0034] Preferably, the drawer plate 466 is fixedly mounted on the second column 461, and the bottom end of the second column 461 is movably mounted inside the load-bearing beam 410, and the drawer plate 466 is adapted to fit on the bottom end plate of the load-bearing beam 410, so as to provide a stabilizing platform for the horizontal movement of the second column 461; The two sets of inner side tightening components 460 are used to provide downward support for the two ends of the inner rib rod 470 extending from the inner side of the vehicle shell, and cooperate with the two sets of inner shell matching components 450 to stretch the inner rib rod 470 and the inner brush roller 480. Finally, the stretched inner brush roller 480 can adapt to and fit the special-shaped area on the inner side of the vehicle shell.

[0035] The working principle and usage process of the present invention are as follows: After the sling 211 suspends the car body directly above the water washing tank 110, the sling 211 is used to immerse the car body into the solution inside the water washing tank 110 until the car body is properly loaded 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 sub-rod rises, and the clamping seat 430 installed at the top of the hydraulic sub-rod in the waterproof hydraulic component 420 will pull the two oblique arms 440 to shrink. At this time, the two sets of shell coordination components 450 will shrink relatively along the slide groove of the top plate of the load-bearing beam 410. As the two sets of shell coordination components 450 continue to shrink, the combined inner rib rod 470 and the 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 is constant, the waterproof hydraulic component 420 can be operated again until its internal hydraulic sub-rod descends, and the two oblique arms 440 pressed downward by the clamping seat 430 will push the two sets of shell coordination components 450 to expand outward until the inner rib rod 470 and the inner brush roller 480 are adapted to the structure inside the vehicle body. At this time, the inner brush roller 480 provides an effective internal cleaning platform for the inner wall of the vehicle body. Then the hydraulic component 140 is operated again. As the hydraulic sub-rod in the hydraulic component 140 falls downward, the suspension plate 150 installed at the top of the hydraulic sub-rod inside it will drive the energy supply component 210 to fall as a whole, and the slider 240 movably installed in the bottom slide groove of the sling 211 and the distance-adjusting suspension 250 will press the two support frames 260 downward until the two support frames 260 are centered and close together under the constraint of the load-bearing beam 410, and the two limit frames 280 are used to limit the lateral movement of the two fixed-distance end heads 270. At this time, the two sets of outer side tightening assemblies 310 installed in the two fixed-distance end heads 270 will continue to fall along the slide groove of the bottom end plate of the load-bearing beam 410. Finally, the two sets of outer side tightening assemblies 310 will adaptably press the outer rib rod 320 and the outer brush roller 330 onto the vehicle body shell. At this time, the outer brush roller 330 will provide an effective external cleaning platform for the vehicle shell. When the motor 214 starts and runs, the transmission shaft inside the motor 214 will cooperate with the driving wheel 215 to drive the transmission belt 216, and the eccentric wheel disc 212 clamped by the sling 211 will drive the pull rod 220 to rotate eccentrically, and 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 overall vibration of the degreasing auxiliary mechanism 200, 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 cooperate with the cleaning solution to perform efficient degreasing and oil removal operations on the vehicle body surface.

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