[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown, a four-wheel positioning lift includes a lifting platform 1, a limiting unit 2, a supporting unit 3, a protective side plate 21, a sliding connecting plate 23, and a front baffle 22. In order to facilitate vehicle entry, a supporting unit 3 for vehicle placement is provided on the lifting platform 1.

[0024] To achieve the goal of shielding the sides of the vehicle tires without affecting the operation of other parts, a portion of the limiting unit 2 is slidably inserted into the supporting unit 3. The limiting unit 2 includes a sliding connecting plate 23 that is partially slidably connected to the supporting unit 3. Both ends of the sliding connecting plate 23 extend outside the supporting unit 3 and are detachably connected to a protective side plate 21 by bolts. To ensure that the protective side plate 21 can limit and shield both sides of the tires, the plane where the highest point of the protective side plate 21 is located is designed to be higher than the plane where the highest point of the supporting unit 3 is located.

[0025] A front baffle 22 is provided between two adjacent protective side plates 21. The highest point of the front baffle 22 should be higher than the center of a normal running tire. The bottom of the front baffle 22 and the top of the sliding connecting plate 23 are detachably connected by bolts. The vehicle tire and the front baffle 22 abut against each other to drive the protective side plates 21 to move. In order to ensure that the tire can drive the front baffle 22 forward, the plane where the highest point of the front baffle 22 is located and the plane where the highest point of the protective side plate 21 is located are designed to be coplanar. When the vehicle tire moves to the position of the front baffle 22, it will abut against the front baffle 22. When the vehicle continues to move forward on the support unit 3, the driver's movement speed will be very slow to ensure safety. The slow movement will not bend the front baffle 22, but will only push the front baffle 22 to drive the sliding connecting plate 23 and the protective side plate 21 forward. At the same time, the highest point of 22 should be higher than the center of a normal running tire to reduce the phenomenon of the anti-skid treads on the wheel getting stuck with the front baffle 22.

[0026] The lateral length of the protective side plate 21 in the above components is not unique and can be varied according to specific needs. Similarly, the distance between the protective side plates 21 is not unique. In order to ensure that the protective side plate 21 is close to the side of the tire and fits the tire, the distance between the protective side plates 21 can be varied according to specific needs.

[0027] The effect achieved by the entire embodiment is that when the vehicle is driven onto the support unit 3, the vehicle tires will come into contact with the front side of the front baffle 22. As the vehicle continues to move forward on the support unit 3, its movement speed will be very slow. The slow movement will not bend the front baffle 22, but will only push the front baffle 22 to drive the sliding connecting plate 23 and the protective side plate 21 to continue forward. At the same time, the protective side plate 21 will shield the sides of the tires, reducing the probability of displacement between the tires and the support unit 3.

[0028] Example 2

[0029] like Figure 1-5 As shown, a four-wheel alignment lift includes a support unit 3 comprising a horizontal plate 31 detachably connected to the bottom of the lift platform 1. The horizontal plate 31 is used for the movement and placement of the vehicle's tires. A sliding member 33 is provided in the horizontal plate 31 for the sliding of the limiting unit 2, thereby limiting the sliding position of the limiting unit 2.

[0030] The sliding member 33 includes a first sliding groove 331 and a second sliding groove 332. The first sliding groove 331 is located inside the horizontal plate 31 and extends laterally through both sides of the horizontal plate 31. The second sliding groove 332 is located at the center of the top of the horizontal plate 31. The second sliding groove 332 is connected to the first sliding groove 331, and the second sliding groove 332 is slidably inserted into the front baffle 22, wherein the front baffle 22 is as follows: Figure 3 The image shown is a vertical design, but it can also be designed horizontally depending on the requirements, such as... Figure 5 The horizontal design shown, if adopted Figure 5 The lateral design allows the second sliding groove 332 at the top of the side support unit 3 to be left ungrooved, and adopts... Figure 5 The design requires that the plane containing the lowest point of the front baffle 22 be higher than the plane containing the highest point of the horizontal plate 31.

[0031] The distance between two adjacent protective side plates 21 is greater than the width of the horizontal plate 31, and the width of the front baffle 22 is less than the width of the sliding member 33, so as to ensure that the entire limiting unit 2 can be displaced on the supporting unit 3.

[0032] A ramp 32 is connected to one end of the horizontal plate 31. The bottom of the ramp 32 is in contact with the ground. The ramp 32 is used for vehicles to enter the horizontal plate 31.

[0033] The effect achieved by the entire second embodiment is that when the vehicle enters the horizontal plate 31 through the inclined plate 32, it will simultaneously drive the protective side plate 21 to move when it comes into contact with the front side of the front baffle 22, thereby limiting the tire position.

[0034] Example 3

[0035] like Figure 1-4As shown, a four-wheel positioning lift has columns 11 inserted at the four corner positions inside the lifting platform 1, and the lifting platform 1 slides longitudinally on the columns 11.

[0036] A drive unit mounting part 12 is provided at the center position below the lifting platform 1. A drive unit is detachably connected to the drive unit mounting part 12. The drive unit is connected to the bottom of the lifting platform 1. The drive unit should contain at least one cylinder for lifting the lifting platform 1.

[0037] The bottom of the column 11 extends to the bottom of the lifting platform 1 and is bolted to a base 13, which is connected to the ground. The bottom of the base 13 and the bottom of the drive unit mounting part 12 are bolted together. The base 13 is connected to the limiting unit 2, and the bottoms of both the base 13 and the limiting unit 2 are bolted to the ground. This allows the drive unit on the limiting unit 2 to lift the lifting platform 1 and the components on top of it, while ensuring that the lifting platform 1 can slide longitudinally on the column 11.

[0038] The effect achieved by the entire embodiment 3 is that the base 13, the drive component mounting part 12 and the ground are fixedly connected by bolts, flanges and the like. Then, an external power supply and controller are connected. The controller controls the drive unit fixedly connected to the drive component mounting part 12 to lift the lifting platform 1, increasing the height of the vehicle on the lifting platform 1 and making it easier for staff to carry out vehicle maintenance later.

[0039] Working principle: When using this four-wheel alignment lift with an external power supply, first check whether all components are installed completely. Then, move the vehicle onto the horizontal plate 31 through the ramp 32. At this time, the vehicle tires will contact the front side of the front baffle 22. As the vehicle moves forward on the support unit 3, its movement speed will be very slow. The slow movement will not bend the front baffle 22, but will only push the front baffle 22 to drive the sliding connecting plate 23 and the protective side plate 21 forward. At the same time, the protective side plate 21 will shield the sides of the tires, reducing the probability of misalignment between the tires and the support unit 3.

[0040] Finally, the base 13, drive unit mounting part 12 and the ground are fixedly connected by bolts, flanges and other means. Then, an external power supply and controller are connected. The controller controls the drive unit fixedly connected to the drive unit mounting part 12 to lift the lifting platform 1, increasing the height of the vehicle on the lifting platform 1 and the ground, which facilitates the maintenance of the vehicle by the staff later. Finally, the work of the four-wheel alignment lift is completed.
