Description

Technical Field

[0001] This utility model relates to the field of automotive repair equipment technology, specifically to a lifting platform for automotive repair. Background Technology

[0002] An automobile is a vehicle that is powered by its own energy and can move freely without relying on tracks or electricity. In a broader sense, any vehicle with four wheels is generally called an automobile. With the continuous development and popularization of automobiles, the maintenance and repair of automobiles has also formed the auto repair industry. In order to improve the efficiency of maintenance and repair, auto repair workbenches were thus created.

[0003] The prior art discloses a car repair workbench with easy lifting and lowering, application number CN201920145404.8, including a base, a ramp, a lifting device, and a lifting platform. A ramp is fixedly connected to one side of the base, and a lifting device is fixedly connected inside the base. The lifting platform is fixedly connected to the upper surface of the lifting device. A front stop is fixedly connected to one end of the upper surface of the lifting platform, and a rear stop is movably connected to the other end of the upper surface of the lifting platform. This utility model improves the repair efficiency of the workbench by setting a lifting device; reduces damage to the workbench by setting a first buffer layer, a second buffer layer, and a third buffer layer; further supports and fixes the workbench by setting a first support rod and a second support rod, improving overall stability and safety performance; and makes fixing the wheel wells more secure and convenient by setting an infrared sensor in the front stop.

[0004] However, the distance between the front and rear stops of the device is fixed, while different vehicles have different lengths, so the distance between the front and rear wheels is also different. As a result, the front and rear stops cannot limit and fix the wheels. At the same time, during vehicle maintenance, engine oil or coolant will inevitably drip onto the base, causing contamination of the maintenance table and making it easy for the feet to slip, which poses a safety hazard. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a lifting platform for automobile repair to solve the technical problems mentioned above in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting platform for automobile repair, comprising a base, four sets of support frames on the top of the base, and a first lead screw installed inside the four sets of support frames.

A second motor is provided inside the lifting platform, and a toothed rod is provided on the inner wall of the lifting platform. A bidirectional lead screw is connected to the output end of the second motor. A second threaded block is sleeved on the outer surface of the bidirectional lead screw. A threaded cylinder is installed on the top of the second threaded block, and a threaded rod is installed inside the threaded cylinder. The base has a stop block fixed at one end, and a gear is provided on the outer surface of the threaded cylinder. A first motor and a piston box are installed inside the base, and the output end of the first motor is connected to a first lead screw. The bottom end of one set of first lead screws is fixed with a driving bevel gear. A second lead screw is installed on one side of the piston box. One end of the second lead screw is fixed with a driven bevel gear, and a threaded seat is provided on the outer surface of the second lead screw. A piston rod is fixed on one side of the threaded seat, and one end of the piston rod extends into the interior of the piston box and is fixed with a piston plate. A water tank is provided on one side of the base. A water pump pipe and a water delivery pipe are connected to the outer surface of the piston box, and one end of the water pump pipe is connected to the water tank.

[0007] Furthermore, the outer surface of the water supply pipe is provided with several sets of nozzles, and the several sets of nozzles are evenly distributed at equal intervals.

[0008] By adopting the above technical solution, hot water can be sprayed evenly through several sets of nozzles, thus achieving a more ideal cleaning effect on oil stains.

[0009] Furthermore, both the water supply pipe and the water pumping pipe are equipped with one-way valves on their outer surfaces.

[0010] By adopting the above technical solution, the one-way valve can control the water in the water supply pipe and the water pumping pipe.

[0011] Furthermore, the first lead screw is provided in four sets, and each of the four sets of the first lead screw is provided with a sprocket at its top, and the outer surface of the sprocket is provided with a chain.

[0012] By adopting the above technical solution, the rotation of one set of lead screws can cause the sprocket to rotate, and under the action of the chain, the four sets of first lead screws can rotate synchronously.

[0013] Furthermore, the inner wall of the piston box is provided with two sets of heating blocks.

[0014] By adopting the above technical solution, the heating block can be heated with clean water, and the hot water can quickly decompose the oil stains, making the oil stain cleaning effect more ideal.

[0015] Furthermore, the outer surface of the base is provided with a control panel, and the heating block, the first motor and the second motor are all electrically connected to the control panel.

[0016] By adopting the above technical solution, staff can control the heating block, the first motor, and the second motor through the control panel.

[0017] Furthermore, the base has receiving slots on both sides of its top, and the lifting platform is adapted to the receiving slots.

[0018] By adopting the above technical solution, the receiving slot can accommodate the lifting platform, thus facilitating the vehicle to drive to the top of the lifting platform.

[0019] Furthermore, a ramp is provided on one side of the base, and a water return outlet and anti-slip strip are provided at the top of the ramp, and a drain outlet is provided on the outer surface of the ramp.

[0020] By adopting the above technical solution, the ramp facilitates the vehicle's exit from the lifting platform, the anti-slip strips prevent the wheels from slipping, the return water inlet can recycle oily wastewater, the oily wastewater is collected in the ramp, and the drain outlet can discharge the oily wastewater.

[0021] Furthermore, the base has several sets of guide strips at the top center.

[0022] By adopting the above technical solution, the flow guide strip can enhance the friction of the workers' feet, making it less likely to slip, and can also guide the hot water to flow and wash along the flow guide strip.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model comprises a second motor, a bidirectional lead screw, a rack, a gear, a threaded cylinder, a threaded rod, and a stop block. During maintenance, the worker drives the vehicle onto the lifting platform, then starts the second motor. The rotation of the second motor causes the bidirectional lead screw to rotate, which in turn causes the second threaded block to move in opposite directions. The movement of the second threaded block causes the threaded cylinder to move, which in turn causes the gear to mesh with the rack. The rotation of the gear drives the threaded cylinder to rotate, and the rotation of the threaded cylinder causes the threaded rod to push the stop block up. After the stop block is raised, the second threaded block continues to move, allowing the stop block to move to the position of the front and rear wheels, thus achieving the purpose of limiting the front and rear wheels. After maintenance is completed, the second motor rotates in the opposite direction, causing the two sets of second threaded blocks to move towards each other. When they reach a certain position, the gear meshes with the rack again, causing the threaded cylinder to rotate in the opposite direction. This causes the threaded rod to drive the stop block downward, allowing the stop block to retract into the lifting platform. This provides a more stable and convenient fixation, has a wide range of applications, and can limit the movement of different vehicle models.

[0025] 2. This utility model comprises a second lead screw, a driving bevel gear, a driven bevel gear, a threaded seat, a piston rod, a piston plate, a piston box, a water suction pipe, a water delivery pipe, and a nozzle. When the first lead screw rotates and drives the lifting platform upward, the rotation of the first lead screw causes the driving bevel gear to rotate, which in turn causes the driven bevel gear to rotate. The rotation of the driven bevel gear causes the second lead screw to rotate, which in turn causes the threaded seat to move to the left. This causes the piston rod to move the piston plate to the left, thereby drawing clean water from the water tank through the water suction pipe. The heating block heats the clean water. When the vehicle is repaired, the first lead screw rotates in the opposite direction, causing the lifting platform to support the vehicle and move downward. This causes the driving bevel gear to rotate in the opposite direction, which in turn causes the second lead screw to rotate in the opposite direction. The threaded seat causes the piston rod to move to the right, and the piston plate pushes the hot water in the piston box into the water delivery pipe. The hot water is sprayed out through the nozzle, thereby washing away the oil stains on the surface of the base and achieving the purpose of cleaning the oil stains. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1: A lifting platform for automobile repair, such as Figures 1-7 As shown, the system includes a base 1, with four sets of support frames 5 on top. A first lead screw 14 is installed inside each set of support frames 5. A first threaded block 15 is provided on the outer surface of the first lead screw 14. A lifting platform 6 is fixed to the outer surface of the first threaded block 15 via a connecting rod 16. A second motor 27 is installed inside the lifting platform 6, and a gear 30 is provided on the inner wall of the lifting platform 6. A bidirectional lead screw 28 is connected to the output end of the second motor 27. A second threaded block 29 is sleeved on the outer surface of the bidirectional lead screw 28. A threaded cylinder 31 is installed on the top of the second threaded block 29, and a threaded rod 33 is installed inside the threaded cylinder 31. A stop block 34 is fixed to the top of the threaded rod 33, and a gear 32 is provided on the outer surface of the threaded cylinder 31. A first motor 19 and a piston box 22 are installed inside the base 1, and the output end of the first motor 19 is connected to the first lead screw 14. One set of first lead screws... The bottom end of the rod 14 is fixed with an active bevel tooth 20. A second lead screw 21 is installed on one side of the piston box 22. One end of the second lead screw 21 is fixed with a driven bevel tooth 23. The outer surface of the second lead screw 21 is provided with a threaded seat 24. A piston rod 25 is fixed on one side of the threaded seat 24. One end of the piston rod 25 extends into the interior of the piston box 22 and is fixed with a piston plate 26. A water tank 3 is provided on one side of the base 1. A water pumping pipe 10 and a water supply pipe 11 are respectively connected to the outer surface of the piston box 22. One end of the water pumping pipe 10 is connected to the water tank 3. The outer surface of the water supply pipe 11 is provided with several sets of nozzles 12. The several sets of nozzles 12 are evenly distributed at equal intervals. Hot water can be evenly sprayed out through the several sets of nozzles 12, thereby achieving a more ideal cleaning effect on oil stains. The outer surfaces of the water supply pipe 11 and the water pumping pipe 10 are both provided with one-way valves. The one-way valves can control the water in the water supply pipe 11 and the water pumping pipe 10.

[0037] See Figures 3-4 In the above embodiment, the first lead screw 14 is provided in four sets, and each of the four sets of the first lead screw 14 is provided with a sprocket 17 at its top end. The outer surface of the sprocket 17 is provided with a chain 18. After one set of lead screws rotates, the sprocket 17 can rotate. Under the action of the chain 18, the four sets of first lead screws 14 can rotate synchronously.

[0038] See Figures 1-2 In the above embodiment, the base 1 has receiving grooves 7 on both sides of the top, and the lifting platform 6 is adapted to the receiving grooves 7. The receiving grooves 7 can accommodate the lifting platform 6, thereby facilitating the vehicle to drive to the top of the lifting platform 6.

[0039] See Figures 1-2 In the above embodiment, the top center of the base 1 is provided with several sets of guide strips 9. Under the action of the guide strips 9, firstly, it can enhance the friction of the workers' feet and prevent slipping. Secondly, it can guide the hot water so that the hot water can flow and wash along the guide strips 9.

[0040] Example 2: To improve the rinsing effect on oil stains, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 4 The piston box 22 has two sets of heating blocks 35 on its inner wall. The heating blocks 35 can be heated with water. Hot water can quickly decompose oil stains, making the oil stain cleaning effect more ideal.

[0041] See Figures 1-2 In the above embodiment, the outer surface of the base 1 is provided with a control panel 4, and the heating block 35, the first motor 19 and the second motor 27 are all electrically connected to the control panel 4. The operator can control the heating block 35, the first motor 19 and the second motor 27 through the control panel 4.

[0042] Example 3: To facilitate centralized wastewater treatment, Example 3 is an improvement upon Example 1. (See attached document.) Figure 1 , Figure 2 and Figure 7 The base 1 has a ramp 2 on one side, and the top of the ramp 2 has a water return port 13 and an anti-slip strip 8. The outer surface of the ramp 2 has a drain port 36. The ramp 2 facilitates the vehicle to get off the lifting platform 6. The anti-slip strip 8 can prevent the wheels from slipping. The water return port 13 can recycle oily wastewater. The oily wastewater is collected in the ramp 2. The drain port 36 can discharge the oily wastewater.

[0043] The implementation principle of this utility model is as follows: In use, the operator drives the vehicle onto the lifting platform 6, and then starts the second motor 27. The rotation of the second motor 27 causes the double-acting lead screw 28 to rotate, which in turn causes the second threaded block 29 to move backward. The movement of the second threaded block 29 causes the threaded cylinder 31 to move, thereby causing the gear 32 to mesh with the rack 30. The rotation of the gear 32 drives the threaded cylinder 31 to rotate, and the rotation of the threaded cylinder 31 causes the threaded rod 33 to push the stop block 34 to rise. After the stop block 34 rises, the second threaded block 29 continues to move, allowing the stop block 34 to move to the position of the front and rear wheels, thus achieving the purpose of limiting the front and rear wheels. Then, the operator starts the first motor 19, which causes the first lead screw 14 to rotate, thereby causing the first threaded block 15 to move upward. This allows the lifting platform 6 to support the vehicle and move upward. After the first lead screw 14 rotates, it drives the lifting platform 6 to move upward. During the upward movement, the rotation of the first lead screw 14 causes the active bevel gear 20 to rotate, which in turn causes the driven bevel gear 23 to rotate. The rotation of the driven bevel gear 23 causes the second lead screw 21 to rotate, which in turn causes the threaded seat 24 to move to the left. This causes the piston rod 25 to drive the piston plate 26 to move to the left, thereby drawing clean water from the water tank 3 through the water pipe 10. The heating block 35 can heat the clean water. When the vehicle is repaired, the first lead screw 14 rotates in the opposite direction, causing the lifting platform 6 to support the vehicle and move downward. This causes the active bevel gear 20 to drive the driven bevel gear 23 to rotate in the opposite direction, thereby causing the second lead screw 21 to rotate in the opposite direction. The threaded seat 24 drives the piston rod 25 to move to the right, and the piston plate 26 pushes the hot water in the piston box 22 into the water supply pipe 11. The hot water is sprayed out through the nozzle 12, thereby washing away the oil stains on the surface of the base 1. The washed wastewater is collected in the ramp 2.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
