Description

Technical Field

[0001] This invention relates to the field of automotive repair equipment technology, specifically to an automotive repair and cleaning lift. Background Technology

[0002] During maintenance, a lifting platform is typically used to raise a car or other vehicle to a suitable height for repair, inspection, and maintenance. There are two existing types of lifting platforms: one type involves driving the car directly onto the platform, securing the tires to prevent movement, and then lifting the entire car to the appropriate height; the other type involves the lifting platform supporting the car body while the tires are not positioned on the platform, facilitating tire removal.

[0003] The main function of a car lift is to raise the entire vehicle off the ground, thereby vacating the chassis, wheels, suspension, pipelines, and other lower structures, creating an unobstructed working space. This eliminates the inconvenience of crouching, lying down, or crawling under the car, making it a fundamental piece of equipment in auto repair workshops. To facilitate maintenance work, the chassis usually needs to be thoroughly cleaned after the car is lifted. However, existing car lifts do not have the function of automatically cleaning the car chassis after lifting, requiring workers to manually operate the cleaning equipment, which is not conducive to improving the efficiency of car maintenance. Therefore, a car maintenance and cleaning lift is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive repair and cleaning lift to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automobile repair and cleaning lift, comprising: a lift body and a cleaning mechanism; The cleaning mechanism includes a plate body, with connecting plates symmetrically fixedly connected to one side of the plate body. One end of the connecting plates is fixedly connected to the frame of the lifting machine body. A hollow groove is opened inside the plate body, and a movable plate is movably connected inside the hollow groove. A water supply hose is fixedly embedded inside the movable plate, and one end of the water supply hose is connected to a hollow shell. The outer side of the hollow shell is fixedly connected to the movable plate. Spray nozzles are evenly connected to the top of the hollow shell. A rack is fixedly connected to one side of the movable plate. A forward and reverse motor is fixedly installed inside the hollow groove. A gear is fixedly connected to the output shaft of the forward and reverse motor, and the outer side of the gear meshes with the rack.

[0006] By adopting the above technical solution, after the car is driven to the middle position inside the lift body and lifted, the forward and reverse motor can be started to drive the gear to rotate clockwise and counterclockwise. This allows the rack to drive the movable plate to move back and forth in the slot under the action of the gear. After the external water pump is started, the cleaning water can be delivered to the hollow shell through the water supply hose, so that the nozzle can spray the water in the hollow shell upward to clean the car chassis. The nozzle can also move back and forth during the spraying process.

[0007] Preferably, the end of the water delivery hose away from the hollow shell is connected to the outlet of the external water pump.

[0008] By adopting the above technical solution, the external water pump can deliver cleaning water to the water delivery hose after it is started, and the length of the water delivery hose can meet the back-and-forth movement of the movable plate.

[0009] Preferably, a slide rail is fixedly installed on the inner side wall of the slot, and a slider is slidably connected inside the slide rail, with one side of the slider being fixedly connected to the movable plate.

[0010] By adopting the above technical solution, the movable plate can always maintain a stable linear movement under the action of gears.

[0011] Preferably, a controller is fixedly installed on the outer side of the plate, and the electrical control output terminal of the controller is electrically connected to the electrical control input terminal of the forward and reverse motor.

[0012] By adopting the above technical solution, it is possible to control the operating status of the forward and reverse motor in real time, and to set the forward and reverse switching parameters of the forward and reverse motor.

[0013] Preferably, the electrical control output terminal of the controller is electrically connected to the electrical control input terminal of the external water pump.

[0014] By adopting the above technical solution, it is easy to control the start and stop of the external water pump.

[0015] Preferably, both the outer sides of the plate and the lifting machine body are fixedly connected to a fixing block.

[0016] By adopting the above technical solution, it is easy to fix and install the plate and the lifting machine body.

[0017] Preferably, the fixing block has symmetrical through holes inside.

[0018] By adopting the above technical solution, after the pre-embedded studs penetrate the through holes, the fixing blocks can be fixed by tightening the threaded sleeves on the studs, which facilitates the stable installation of the plate and the lifting machine body.

[0019] Preferably, the number of nozzles is several, and the several nozzles are distributed in a fan shape on the top of the hollow shell.

[0020] By adopting the above technical solution, the spray range of the nozzle can be increased, thereby enabling the car chassis to undergo a more comprehensive cleaning treatment.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This car repair and cleaning lift incorporates a cleaning mechanism on its main body. After the car is lifted, the motor drives a movable plate to move back and forth via gears and racks. This, in turn, causes the hollow housing to drive the nozzles to automatically spray water onto the car's chassis. This design enables the lift to automatically clean the car's chassis, thereby improving the efficiency of car repair work. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1 Please see Figures 1-6 The present invention provides a technical solution: an automobile repair and cleaning lift, comprising: a lift body 1 and a cleaning mechanism 2; First, in order for the car to be lifted to the middle position inside the lift body 1, the forward and reverse motor 28 can be started to drive the gear 27 to rotate clockwise and counterclockwise. This allows the rack 26 to drive the movable plate 22 to move back and forth in the slot 203 under the action of the gear 27. After the external water pump is started, the cleaning water can be delivered to the hollow shell 24 through the water delivery hose 23, so that the nozzle 25 can spray the water in the hollow shell 24 upward to clean the car chassis. The nozzle 25 can move back and forth during the spraying process. The cleaning mechanism 2 includes a plate 21, and a connecting plate 20 is symmetrically fixedly connected to one side of the plate 21. One end of the connecting plate 20 is fixedly connected to the frame of the lift body 1. The interior of the plate 21 is opened There is a hollow trough 203, and a movable plate 22 is movably connected inside the hollow trough 203. A water supply hose 23 is fixedly embedded inside the movable plate 22. One end of the water supply hose 23 is connected to a hollow shell 24. The outer side of the hollow shell 24 is fixedly connected to the movable plate 22. Spray nozzles 25 are evenly connected to the top of the hollow shell 24. A rack 26 is fixedly connected to one side of the movable plate 22. A forward and reverse motor 28 is fixedly installed inside the hollow trough 203. A gear 27 is fixedly connected to the output shaft of the forward and reverse motor 28. The outer side of the gear 27 is meshed with the rack 26. In order to deliver cleaning water to the water supply hose 23 after the external water pump is started, and the length of the water supply hose 23 is sufficient to allow the movable plate 22 to move back and forth, the end of the water supply hose 23 away from the hollow shell 24 is connected to the outlet of the external water pump. Secondly, in order to ensure that the movable plate 22 maintains a smooth linear movement under the action of the gear 27, a slide rail 201 is fixedly installed on the inner wall of the slot 203, and a slider 29 is slidably connected inside the slide rail 201. One side of the slider 29 is fixedly connected to the movable plate 22. In order to facilitate real-time control of the operating status of the forward and reverse motor 28 and to set the forward and reverse switching parameters of the forward and reverse motor 28, a controller 202 is fixedly installed on the outer side of the plate 21. The electrical control output terminal of the controller 202 is electrically connected to the electrical control input terminal of the forward and reverse motor 28. In order to facilitate the start and stop control of the external water pump, the electrical control output terminal of the controller 202 is electrically connected to the electrical control input terminal of the external water pump. In order to increase the spray range of the nozzle 25, so that the car chassis is cleaned more thoroughly, there are several nozzles 25, and the several nozzles 25 are distributed in a fan shape on the top of the hollow shell 24. Furthermore, in order to secure the fixing block 10 by tightening the screw sleeve on the pre-embedded stud through the through hole 11, thereby facilitating the stable installation of the plate 21 and the lifting machine body 1, fixing blocks 10 are fixedly connected to the outer sides of both the plate 21 and the lifting machine body 1, and through holes 11 are symmetrically opened inside the fixing blocks 10; in order to ensure that the gear 27 and rack 26 can be used effectively for a long time, both gear 27 and rack 26 are made of stainless steel, and the staff can clean the tooth grooves of gear 27 and rack 26 regularly as needed.

[0026] It should be noted that the model of the lift body 1 is TLT235SC.

[0027] Example 2 Please refer to the following: Figures 1 to 6 As shown in the figure. This embodiment provides an automotive maintenance and cleaning lift, including: a lift body 1 and a cleaning mechanism 2.

[0028] The cleaning mechanism 2 includes a plate 21, which is fixedly connected to the frame of the lifting machine body 1 via a connecting plate 20. A slot 203 is formed inside the plate 21, and a movable plate 22 is movably disposed within the slot 203. A water supply hose 23 is embedded inside the movable plate 22, one end of which is connected to a hollow shell 24. Multiple fan-shaped nozzles 25 are evenly connected to the top of the hollow shell 24.

[0029] Unlike Embodiment 1, in this embodiment, to achieve precise cleaning of the car chassis without blind spots, a limit switch (not shown) or a position sensor (e.g., an infrared photoelectric sensor) is fixedly installed on the bottom of the movable plate 22, and trigger stops are provided at corresponding positions on both ends of the inner wall of the empty groove 203. The signal output terminal of the limit switch or position sensor is electrically connected to the signal input terminal of the controller 202.

[0030] In addition, a rack 26 is fixedly connected to one side of the movable plate 22, and a forward and reverse motor 28 is fixedly installed inside the slot 203. A gear 27 is fixedly connected to the output shaft of the forward and reverse motor 28, and the gear 27 meshes with the rack 26. The electrical control output terminal of the controller 202 is electrically connected to the electrical control input terminal of the forward and reverse motor 28 and the external water pump.

[0031] The working principle of this embodiment is as follows: After the car is lifted to a predetermined height by the lift body 1, the cleaning program is started by the controller 202. The controller 202 first starts the external water pump, and the cleaning water is sprayed upward from the nozzle 25 after passing through the water delivery hose 23 and the hollow shell 24. At the same time, the controller 202 controls the forward and reverse motor 28 to rotate forward, driving the movable plate 22 to move horizontally from one end of the empty slot 203 to the other end, driving the nozzle 25 to perform a one-way spray on the car chassis. When the movable plate 22 moves to the other end, when the limit switch or position sensor on it contacts the trigger stop, it immediately sends a reversing signal to the controller 202. After receiving the signal, the controller 202 controls the forward and reverse motor 28 to rotate in the reverse direction, driving the movable plate 22 to perform a reverse horizontal spray. Through the above reciprocating motion, this embodiment can realize the automatic reciprocating and limit reversing of the nozzle 25 under the car chassis, without the need for manual setting of the motor forward and reverse switching parameters, further improving the automation level of cleaning and the accuracy of path coverage.

[0032] As a further optimization, in addition to the nozzle 25, the top of the hollow housing 24 is also equipped with a row of high-pressure nozzles, the orifice diameter of which is smaller than that of the nozzle 25. An external water pump can be a variable frequency water pump. When cleaning stubborn stains, the controller 202 can control the water pump to increase the output pressure, using the high-pressure nozzles to perform powerful cleaning on specific areas of the chassis; during regular cleaning or rinsing, the water pump pressure is reduced, allowing for large-area coverage using the ordinary nozzles 25. Through these settings, this embodiment not only achieves automatic reciprocating cleaning but also has the function of distinguishing between regular cleaning and high-pressure cleaning, significantly improving the cleaning effect and applicability.

[0033] Example 3 Please see Figures 1 to 6 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, including a lifting body 1 and a cleaning mechanism 2. The cleaning mechanism 2 includes a plate 21, a movable plate 22, a water supply hose 23, a hollow shell 24, a nozzle 25, a rack 26, a gear 27, a forward and reverse motor 28, and other components, and their connection relationship is the same as that of Embodiment 1.

[0034] The difference in this embodiment is that a water collection trough (not shown) is provided at the top outer edge of the plate 21, and the water collection trough is arranged in a closed manner around the plate 21. A drain outlet is provided at the bottom of the water collection trough, and the drain outlet is connected to a sewage collection tank (not shown) located on one side of the lifting machine body 1 through a drain pipe. A filter screen can be installed inside the sewage collection tank to intercept large particles of impurities such as silt and sand.

[0035] Preferably, the inner wall of the water collection tank, i.e. the side facing the center of the plate 21, is set as an inclined guide surface, so that the sewage dripping after spraying can flow smoothly into the bottom of the water collection tank and prevent water accumulation.

[0036] To facilitate the rapid removal of residual water droplets after the car chassis is cleaned, this embodiment also includes a drying mechanism on the movable plate 22. Specifically, an air supply pipe is embedded inside the movable plate 22. One end of the air supply pipe is connected to an external compressed air source (such as an air pump or air tank), and the other end is connected to a hollow air blowing pipe. The hollow air blowing pipe is arranged side by side with the hollow housing 24, and its top is evenly provided with multiple air outlets. A solenoid valve is installed on the air supply pipe, and the electrical control input terminal of the solenoid valve is electrically connected to the electrical control output terminal of the controller 202.

[0037] The working principle of this embodiment is as follows: After the automatic spray cleaning of the car chassis is completed, the controller 202 first shuts off the external water pump and stops spraying water. Then, the controller 202 controls the forward and reverse motor 28 to drive the movable plate 22 to move back and forth again, while simultaneously opening the solenoid valve, so that compressed air is sprayed out at high speed from the air outlet after passing through the air supply pipe and the hollow air blowing pipe, to blow clean the wet car chassis, accelerate the evaporation or dripping of moisture on the chassis surface, and prevent the parts from rusting due to prolonged dampness. The cleaning wastewater dripping from the chassis flows along the plate 21 into the surrounding water collection tank, and then flows into the sewage collection tank through the drainage pipe, realizing the centralized collection and treatment of wastewater, avoiding sewage flowing around the work site, and significantly improving the environmental friendliness and cleanliness of the working environment.

[0038] With the above settings, this embodiment, in addition to having automatic cleaning function, further integrates wastewater recycling and rapid drying functions, forming a complete automobile chassis cleaning operation system, which greatly improves the integration, automation and environmental protection level of auto repair shops.

[0039] Based on the above technical solution, the working steps of this solution are summarized as follows: When in use, after the car is driven to the middle position inside the lift body 1 and lifted, the forward and reverse motor 28 can be started to drive the gear 27 to rotate clockwise and counterclockwise. This allows the rack 26 to drive the movable plate 22 to move back and forth in the empty slot 203 under the action of the gear 27. After the external water pump is started, the cleaning water can be delivered to the hollow shell 24 through the water delivery hose 23. Then, the nozzle 25 can spray the water in the hollow shell 24 upward to clean the car chassis. The nozzle 25 can move back and forth during the spraying process.

[0040] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
