[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic that liquid can evenly transmit force during the squeezing process to set up an adjustment mechanism. When using the device, first install the device. After the base is firmly installed, rotate the limit block 1 into the limit groove, then turn on the power to start the hydraulic cylinder. The hydraulic cylinder will squeeze the slider 2 upward. The cavity 1 is filled with liquid. The slider 2 slides upward to squeeze the liquid in the cavity 1. After being squeezed, the liquid flows from the cavity 1 into the cavity formed between the baffle 1 and the T-shaped support arm and the slide groove 2. The liquid squeezes the baffle 1 and the T-shaped support arm. The T-shaped support arm and the baffle 1 move outward and extend under the squeeze of the liquid. When the limit rod contacts the car, the car will give the baffle 1 an interaction force through the limit rod to offset the force of the liquid squeezing the baffle 1. At this time, the baffle 1 is in a force balance state, and the bottom of the T-shaped support arm is still subject to pressure from the liquid, so the baffle 1 and the T-shaped support arm will slide apart, so that the lateral distance between the lift and the car can be adjusted according to different vehicles.

[0020] (2) The present invention utilizes the characteristic that the pressure of the above-mentioned liquid in all directions is equal after being squeezed to set a stabilizing component. When the lateral distance is adjusted, the power is turned off, the hydraulic pressure stops moving, and the limit block 1 is rotated out of the limit groove. The power is turned on, and the hydraulic cylinder continues to squeeze upward. The liquid will enter the cavity 7 through the cavity 6, and then flow into the cavity 2 through the holes inside the connecting pipe. Two springs are arranged inside the cavity 2 to make the rubber plug close to the inner wall. The two sides of the cavity 2 are not connected to each other. When the pressure on the side of the cavity 2 connected to the connecting pipe increases, the inner wall will be pressed. The rubber plug near the connecting pipe is squeezed and the spring 1 is stretched. The liquid enters the other side of the cavity 2 from the hole near the connecting pipe, and then the liquid enters the cavity 4 through the cavity 3. The liquid pressure in the cavity 4 gradually increases, which squeezes the piston 2 to slide in the cavity 4, thereby driving the support arm 2 to slide inside the slide groove 4 to extend the support arm 2 outward. When the support arm 2 is extended outward, the liquid pressure on the side where the connecting pipe is located is equal to that on the other side in the cavity 2. The force analysis of the rubber plug near the connecting pipe can be It can be seen that at this time, the liquid on both sides of the rubber plug is in a dynamic equilibrium state, and the pressure of the liquid on both sides is equal. The side of the rubber plug connected to the spring one will also be subject to the force of the spring one to reset, driving the rubber plug to return to the initial closed state. During the extension of the support arm two, the pressure on one side of the connecting pipe will never be less than the other side, so the rubber plug on the side of the cavity four will always be in place. Therefore, at this time, the cavity two on the side away from the connecting pipe will be in a closed state with constant pressure. When the device is used, the hydraulic rod shrinks, and the pressure on one side of the connecting pipe in the cavity two will decrease. At this time, the pressure on the other side is greater than the side where the connecting pipe is located. The rubber plug on the side away from the connecting pipe opens, and the rubber plug on the side close to the connecting pipe is always in the initial state. Therefore, the pressure on the side of the cavity two away from the connecting pipe will also decrease accordingly, and the reverse flow pressure of the liquid decreases. The piston two moves toward the cavity three inside the cavity four, driving the support arm two to shrink, increasing the contact area and contact point between the lift and the car, so that the force on the vehicle during the lifting process is more uniform and stable, and better adapted to models with different shapes and weight distributions.

[0021] (3) The present invention utilizes the characteristic that the above-mentioned liquid will not be compressed to provide an anti-skid component. During the lifting process, since the bottom of the car is not smooth and has irregular bumps, the limit block 2 in contact with the car chassis will be pressed downward by the pressure of the car to squeeze the slider 3, thereby squeezing the liquid in the cavity 5. The limit block 2 not in contact with the car is supported by the upward force of the slider 3 under the action of the liquid pressure. Similarly, inside the support arm 3, the limit block 2 in contact with the car chassis will be pressed downward by the pressure of the car to squeeze the slider 3, thereby squeezing the liquid. The limit block 2 not in contact with the car is supported by the upward force of the slider 3 under the action of the liquid pressure, so that the car can be limited to prevent the car from rolling over due to shaking during the lifting process.

[0022] (4) The present invention utilizes the characteristic of generating centrifugal force by rotation to provide a self-locking component. When the device is in use, the slider 1 slowly rises. If the hydraulic cylinder fails, the slider 1 quickly falls. The slider 1 drives the gear 1 to rotate, and the gear 1 drives the gear 2 to rotate quickly. When the speed becomes faster, the slider 4 inside the gear 2 will slide outward inside the slide groove 6 under the action of centrifugal force. The slider 4 will be thrown into the slot to limit the position, so that the slider 1 stops sliding downward, preventing the slider 1 from falling quickly due to a failure of the lift, ensuring the life safety of the safety personnel, and providing time for escape.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] For example, see Figure 1-Figure 11As shown, the present invention is a car maintenance docking platform, 1. A car maintenance docking platform, comprising a base 1, a support frame 11 is fixedly connected to the top of the base 1, a hydraulic cylinder 12 is fixedly connected to the inside of the base 1, a slide groove 13 is provided at the left and right side walls of the support frame 11, a limiting groove 14 is provided at the side wall of the support frame 11, and a limiting block 15 is rotatably connected to the inner wall of the limiting groove 14;

[0045] The adjusting mechanism 2 includes a T-shaped support arm 25, a slider 1 21 for extending the T-shaped support arm 25, a cavity 1 22, a slider 23, a slide groove 24, and a limit assembly 6 for limiting the extension length of the T-shaped support arm 25;

[0046] The side wall of the slider 21 is slidably connected to the inner wall of the slide groove 13, the cavity 22 is opened on the inner wall of the slider 21, the side wall of the slider 23 is slidably connected to the inner wall of the cavity 22, the slide groove 24 is opened on the inner wall of the slider 21, the side wall of the T-shaped support arm 25 is slidably connected to the inner wall of the slide groove 24, the limiting component 6 includes a baffle 61 slidably connected to the inside of the slide groove 24, the side wall of the baffle 61 is slidably connected to the side wall of the T-shaped support arm 25, the side wall of the T-shaped support arm 25 slides through the limiting rod 62 and extends to the outside, the left extension of the limiting rod 62 is connected to the baffle The inner wall of the T-shaped support arm 25 is fixedly connected to the side wall of the cavity 61, a cavity 63 is opened on the inner wall of the T-shaped support arm 25, and a sliding groove 7 64 is opened on the inner wall of the front and rear sides of the T-shaped support arm 25. The limiting component 6 also includes a support arm 3 65 slidably connected to the inner wall of the sliding groove 7 64, and a cavity 7 66 is opened on the inner wall of the front and rear sides of the T-shaped support arm 25. The inner walls of the two cavities 7 66 are connected to the inner wall of the cavity 63, and the inner walls of the cavities 7 66 are slidably connected to the side wall of the cavity 63. A connecting pipe 67 is slidably connected to the inner wall of the cavity 7 66, and the end of the connecting pipe 67 away from the limiting rod 62 is fixedly connected to the side wall of the support arm 3 65. The side wall of the T-shaped support arm 25 The limiting slider 68 is fixedly connected to the wall, and the side wall of the limiting slider 68 is slidably connected to the outer wall of the through hole of the baffle 1 61. A stabilizing component 3 is arranged on the support arm 3 65. When in use, the device needs to be installed first. After the base is firmly installed, the limiting block 15 is rotated into the limiting groove 14, and then the power is turned on to start the hydraulic cylinder 12. The hydraulic cylinder 12 will squeeze the slider 23 upward. There is liquid in the cavity 1 22. The slider 23 slides upward to squeeze the liquid in the cavity 1 22. After being squeezed, the liquid flows from the cavity 1 22 into the baffle 1 61 and the T-shaped support arm 25 and the slide groove 24 In the cavity formed between the two, the liquid will squeeze the baffle 61 and the T-shaped support arm 25, and the T-shaped support arm 25 and the baffle 61 will move outward under the squeeze of the liquid. When the limit rod 62 contacts the car, the car will give the baffle 61 an interaction force through the limit rod 62 to offset the force of the liquid squeezing the baffle 61. At this time, the baffle 61 is in a force balance state, and the bottom of the T-shaped support arm 25 is still subject to the pressure from the liquid, so the baffle 61 and the T-shaped support arm 25 will slide apart, so that the lateral distance between the lift and the car can be adjusted according to different vehicles.

[0047] For example 2, please refer to Figure 1-Figure 16As shown, the stabilizing component 3 includes a cavity 2 31 opened at the inner wall of the supporting arm 3 65, the inner wall of the cavity 2 31 is connected through the inner wall of the connecting pipe 67, the side wall of the supporting arm 3 65 is fixedly connected with a supporting arm 1 32, the inner walls of the left and right sides of the cavity 2 31 are fixedly connected with springs 1 33, and the ends of the two springs 1 33 facing each other are fixedly connected with rubber plugs 34, the stabilizing component 3 also includes a cavity 35 opened at the inner wall of the supporting arm 3 65, the inner wall of the cavity 35 is connected through the inner wall of the cavity 2 31, a slide groove 4 36 is opened at the inner wall of the supporting arm 1 32, and the inner wall of the slide groove 4 36 is slidably connected with the supporting arm 2 39, the stabilizing component 3 also includes a cavity 4 37 opened at the inner wall of the supporting arm 1 32, and the inner wall of the cavity 4 37 is slidably connected with the supporting arm 2 The piston 2 is dynamically connected with the piston 38, and the end of the piston 2 is far away from the cavity 35 and is fixedly connected with the support arm 2 39. The inner wall of the cavity 4 37 is connected with the inner wall of the cavity 35. The support arm 2 is provided with an anti-skid component 4. When the lateral distance is adjusted, the power is turned off, the hydraulic pressure stops moving, and the limit block 15 is turned out from the limit groove 14. After the power is turned on, the hydraulic cylinder continues to squeeze upward, and the liquid will enter the cavity 7 66 through the cavity 6 63, and then flow into the cavity 2 31 through the holes in the connecting pipe 67. Two springs 1 33 are arranged inside the cavity 2 31 to make the rubber plug 34 close to the inner wall. The two sides of the cavity 2 31 are not connected to each other. When the pressure on the side where the cavity 2 31 is connected with the connecting pipe 67 increases, the inner wall will be squeezed and the liquid will be close to the cavity 2 31. The rubber plug 34 on one side of the connecting tube 67 is squeezed and the spring 1 33 is stretched. The liquid enters the other side of the cavity 2 31 from the hole near the side of the connecting tube 67, and then the liquid enters the cavity 4 37 through the cavity 35. The liquid pressure in the cavity 4 37 gradually increases, which squeezes the piston 2 38 to slide in the cavity 4 37, thereby driving the support arm 2 39 to slide inside the slide groove 4 36 so that the support arm 2 39 extends outward. When the support arm 2 39 is extended outward, at this time in the cavity 2 31, the liquid pressure on this side where the connecting tube 67 is located is equal to that on the other side. It can be seen from the force analysis of the rubber plug 34 near the side of the connecting tube 67 that at this time, the liquid on both sides of the rubber plug 34 is in a dynamic equilibrium state, and the pressure of the liquid on both sides is equal. The side of the rubber plug 34 connected to the spring 1 33 will also be subject to the restoring force of the spring 1 33, driving the rubber plug 34 to return to its initial closed state. During the extension of the support arm 2 39, the pressure on one side of the connecting pipe 67 will never be less than that on the other side. Therefore, the rubber plug 34 on the side of the cavity 4 37 will always be in place. Therefore, at this time, the cavity 2 31 on the side away from the connecting pipe 67 of the cavity 2 will be in a closed state with constant pressure. When the device is used, the hydraulic rod contracts, and the pressure on one side of the connecting pipe 67 in the cavity 2 will decrease. At this time, the pressure on the other side is greater than that on the side where the connecting pipe 67 is located. The rubber plug 34 on the side away from the connecting pipe 67 opens, and the rubber plug 34 on the side close to the connecting pipe 67 is always in the initial state.Therefore, the pressure on the side of cavity 2 31 away from connecting pipe 67 will also decrease, and the pressure of the liquid will decrease when it flows in the opposite direction. Piston 2 38 moves inside cavity 4 37 toward cavity 3 35, driving support arm 2 39 to contract, increasing the contact area and contact points between the lift and the car, making the force on the vehicle more uniform and stable during the lifting process, and better adapting to models with different shapes and weight distributions.

[0048] The anti-skid component 4 includes a cavity 5 41 formed on the inner wall of the support arm 2 39, a plurality of springs 2 42 are fixedly connected to the inner wall of the cavity 5 41, and a slider 3 43 is fixedly connected to one end of the spring 2 42 away from the piston 2 38, and the anti-skid component 4 also includes a limit block 2 44 fixedly connected to the top of the slider 3 43, and a side wall of the limit block 2 44 is slidably connected to the inner wall of the through hole of the support arm 2 39, and a cavity 8 45 is formed on the inner wall of the support arm 3 65, and a plurality of side walls of the limit block 2 44 are slidably connected to the inner wall of the through hole of the support arm 3 65, and an extension portion of the limit block 2 44 is fixedly connected to the top of the slider 3 43, and one end of the spring 2 42 away from the cavity 35 is fixedly connected to the bottom of the slider 3 43, and one end of the spring 2 42 away from the slider 3 43 is fixedly connected to the The inner wall of the cavity eight 45 is fixedly connected, and a self-locking component 5 is arranged inside the support frame 11. During the lifting process, since the bottom of the car is not smooth and has irregular bumps, the limit block two 44 in contact with the chassis of the car will be squeezed downward by the pressure of the car to squeeze the slider three 43, thereby squeezing the liquid in the cavity five 41, and the limit block two 44 not in contact with the car will be supported upward by the slider three 43 under the action of the liquid pressure. Similarly, inside the support arm three 65, the limit block two 44 in contact with the chassis of the car will be squeezed downward by the pressure of the car to squeeze the slider three 43, thereby squeezing the liquid, and the limit block two 44 not in contact with the car will be supported upward by the slider three 43 under the action of the liquid pressure, so that the car can be limited to prevent the car from rolling over due to shaking during the lifting process.

[0049] The self-locking component 5 includes a slide groove 51 provided inside the support frame 11, a gear 52 is rotatably connected to the inner wall of the slide groove 51, the side wall of the gear 52 is meshed with the side wall of the slider 1 21, a gear 2 53 is rotatably connected to the inner wall of the slide groove 51, the side wall of the gear 1 52 is meshed with the side wall of the gear 2 53, the self-locking component 5 also includes a plurality of slide grooves 6 54 provided on the front and rear side walls of the gear 2 53, the inner walls of the slide grooves 6 54 are slidably connected to the slider 4 55, and a plurality of card slots are provided on the inner wall of the support frame 11 56. During the use of the device, the slider 21 rises slowly. If the hydraulic cylinder 12 fails, the slider 21 falls quickly, the slider 21 drives the gear 52 to rotate, and the gear 52 drives the gear 2 53 to rotate quickly. When the speed becomes faster, the slider 4 55 inside the gear 2 53 will slide outward inside the slide groove 6 54 under the action of centrifugal force, and the slider 4 55 will be thrown into the card groove 56 for limiting, so that the slider 21 stops sliding downward, preventing the rapid fall due to the failure of the lift, ensuring the safety of the safety personnel and providing time for escape.

[0050] A specific application of this embodiment is as follows: when in use, the device needs to be installed first, and after the base is firmly installed, the limit block 15 is rotated into the limit groove 14, and then the power is turned on to start the hydraulic cylinder 12, and the hydraulic cylinder 12 will squeeze the slider 23 upwards. The cavity 12 is filled with liquid, and the slider 23 slides upward to squeeze the liquid in the cavity 12. After being squeezed, the liquid flows from the cavity 12 into the cavity formed between the baffle 1 61 and the T-shaped support arm 25 and the slide groove 24. The liquid squeezes the baffle 1 61 and the T-shaped support arm 25. The T-shaped support arm 25 and the baffle plate 61 are squeezed outward by the liquid. When the limit rod 62 contacts the car, the car will give the baffle plate 61 an interaction force through the limit rod 62 to offset the force of the liquid squeezing the baffle plate 61. At this time, the baffle plate 61 is in a force balance state, and the bottom of the T-shaped support arm 25 is still subject to the pressure from the liquid, so the baffle plate 61 and the T-shaped support arm 25 will slide apart, so that the lateral distance between the lift and the car can be adjusted according to different vehicles.

[0051] When the lateral distance is adjusted, the power is turned off, the hydraulic pressure stops moving, the limit block 15 is rotated out of the limit groove 14, the power is turned on, the hydraulic cylinder continues to squeeze upward, the liquid will enter the cavity 7 66 through the cavity 6 63, and then flow into the cavity 2 31 through the holes inside the connecting pipe 67. Two springs 1 33 are arranged inside the cavity 2 31 to make the rubber plug 34 close to the inner wall. The two sides of the cavity 2 31 are not connected to each other. When the pressure on the side where the cavity 2 31 is connected to the connecting pipe 67 increases, the inner wall will be squeezed, and the rubber plug 34 close to the connecting pipe 67 will be squeezed and the spring 1 33 will be stretched, and the liquid The liquid enters the other side of the cavity 2 31 from the hole near the connecting pipe 67, and then the liquid enters the cavity 4 37 through the cavity 35. The liquid pressure in the cavity 4 37 gradually increases, which squeezes the piston 2 38 to slide in the cavity 4 37, thereby driving the support arm 2 39 to slide inside the slide groove 4 36 so that the support arm 2 39 extends outward. When the support arm 2 39 is extended outward, at this time, in the cavity 2 31, the liquid pressure on the side where the connecting pipe 67 is located is equal to that on the other side. It can be seen from the force analysis of the rubber plug 34 near the side of the connecting pipe 67 that at this time, the liquid on both sides of the rubber plug 34 The body is in a state of dynamic equilibrium, and the pressures of the liquid on both sides are equal. The side where the rubber plug 34 is connected to the spring 1 33 is also affected by the restoring force of the spring 1 33, driving the rubber plug 34 to return to the initial closed state. During the extension of the support arm 2 39, the pressure on one side of the connecting pipe 67 will never be less than that on the other side. Therefore, the rubber plug 34 on the side of the cavity 4 37 will always be in place. Therefore, at this time, the cavity 2 31 on the side away from the connecting pipe 67 will be in a closed state with constant pressure. When the device is used, the hydraulic rod will retract, and the connecting pipe 67 in the cavity 2 31 will be closed. The pressure on the side of cavity 2 31 will decrease. At this time, the pressure on the other side is greater than that on the side where the connecting pipe 67 is located. The rubber plug 34 on the side away from the connecting pipe 67 opens, and the rubber plug 34 on the side close to the connecting pipe 67 is always in the initial state. Therefore, the pressure on the side of cavity 2 31 away from the connecting pipe 67 will also decrease accordingly. The pressure of the liquid flows in the opposite direction and decreases. The piston 2 38 moves from the inside of cavity 4 37 to cavity 3 35, driving the support arm 2 39 to contract, thereby increasing the contact area and contact points between the lift and the car, making the force on the vehicle more uniform and stable during the lifting process, and better adapting to models with different shapes and weight distributions.

[0052] During the lifting process, since the bottom of the car is not smooth and has irregular bumps, the limit block 2 44 in contact with the car chassis will be squeezed downward by the pressure of the car to squeeze the slider 3 43, thereby squeezing the liquid in the cavity 5 41, and the limit block 2 44 not in contact with the car will be supported upward by the slider 3 43 under the action of the liquid pressure. Similarly, inside the support arm 3 65, the limit block 2 44 in contact with the car chassis will be squeezed downward by the pressure of the car to squeeze the slider 3 43, thereby squeezing the liquid, and the limit block 2 44 not in contact with the car will be supported upward by the slider 3 43 under the action of the liquid pressure, so that the car can be limited to prevent the car from rolling over due to shaking during the lifting process.

[0053] During the use of the device, the slider 21 rises slowly. If the hydraulic cylinder 12 fails, the slider 21 falls quickly, the slider 21 drives the gear 52 to rotate, and the gear 52 drives the gear 2 53 to rotate quickly. When the speed becomes faster, the slider 4 55 inside the gear 2 53 will slide outward in the slide groove 6 54 under the action of centrifugal force, and the slider 4 55 will be thrown into the card groove 56 for limiting, so that the slider 21 stops sliding downward, preventing the rapid fall due to the failure of the lift, ensuring the safety of the safety personnel and providing time for escape.
