Description

Technical Field

[0001] This invention relates to the field of vehicle repair and manufacturing technology, and in particular to a tire lifting device and tire inspection equipment. Background Technology

[0002] Existing tire lifting devices use cylinders to drive the lifting mechanism of the loaded tires. This requires manual operation of the control valve on the cylinder to control the extension and retraction of the cylinder, thereby controlling the lifting and lowering of the tires.

[0003] Specifically, once the target height to which the tire needs to be raised is determined, the user needs to manually operate the control valve of the cylinder to output power and raise the tire. When the tire is raised to near the target height, the user needs to manually and slightly, in small amounts and multiple times, adjust the position of the tire until it reaches the target height. This process is cumbersome and inefficient. Summary of the Invention

[0004] This invention provides a tire lifting device and tire inspection equipment to solve the problems of existing tire lifting devices that use cylinders to drive the lifting mechanism of the loaded tire. These devices require manual operation of the control valve on the cylinder to control the extension and retraction of the cylinder to control tire lifting. Specifically, once the target height to be lifted is determined, the user needs to manually operate the control valve of the cylinder to output power and lift the tire. When the tire is lifted close to the target height, the user needs to manually and slightly adjust the position of the tire by repeatedly turning the control valve until the tire reaches the target height. This process is cumbersome and inefficient.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0006] In a first aspect, embodiments of the present invention provide a tire lifting device, comprising:

[0007] The base includes: a base plate and a standing base disposed on the base plate;

[0008] A lifting mechanism, mounted on the stand, is used to lift or lower the loaded tire along the length of the stand.

[0009] A limiting device is provided on the stand and located above the lifting mechanism, which can both rise or fall along the length of the stand and rotate relative to the stand.

[0010] The limiting device and the lifting mechanism are linked together by a linkage mechanism. When the lifting mechanism is rising, it links the limiting device to descend, and when the lifting mechanism is descending, it links the limiting device to rise.

[0011] The power unit has a power output end connected to the lifting mechanism, and the power unit is connected to the power source through the limiting device;

[0012] The limiting device has a first limiting angle, and when the limiting device rotates to the first limiting angle, it cuts off the connection between the power device and the power source.

[0013] Optionally, the linkage mechanism includes:

[0014] The pulley has two pulleys, which are arranged one above the other on the stand with their axes parallel to each other.

[0015] The flexible cable is sleeved between the two pulleys and has two side sections located between the two pulleys and opposite to each other. One side section is connected to the lifting mechanism and the other side section is connected to the limiting device.

[0016] Optionally, the power unit includes: a cylinder, and a pneumatic control valve for controlling the extension and retraction of the cylinder; the power source is an air source.

[0020] A first valve is provided on the limiting seat. The contraction control valve port of the pneumatic control valve is connected to the air source through the first valve. When the contraction control valve port is connected to the air source, the pneumatic control valve controls the cylinder to contract. The first valve is used to control the connection or disconnection between the contraction control valve port and the air source.

[0021] A limiting component is rotatably mounted on the limiting seat and connected to the first valve. When the limiting component rotates to the first limiting angle, it triggers the first valve to control the contraction control valve port to disconnect from the air source.

[0022] Optionally, the first valve includes: a valve body, a first opening and a second opening disposed in the valve body, and a spring-loaded mechanical switch mechanism disposed in the valve body;

[0023] The first opening and the second opening are connected through the valve cavity of the valve body. The first opening is connected to the air source, and the second opening is connected to the contraction control valve port. The spring-loaded mechanical switch mechanism is used to control the connection and disconnection between the first opening and the second opening.

[0024] The limiting component is connected to the spring-loaded mechanical switch mechanism. When the limiting component rotates to the first limiting angle, it triggers the spring-loaded mechanical switch mechanism to control the disconnection between the first opening and the second opening.

[0025] Optionally, it also includes:

[0026] A manual control valve is located between the first valve and the gas source, used to control the connection or disconnection between the first valve and the gas source;

[0027] The manual control valve is also connected to the extension control valve port of the pneumatic control valve, and is used to control the connection or disconnection between the extension control valve port and the air source. When the extension control valve port is connected to the air source, the pneumatic control valve controls the cylinder to extend.

[0028] When the manual control valve controls the first valve to be connected to the air source, it controls the extension control valve port to disconnect from the air source.

[0029] When the manual control valve controls the extension control valve port to be connected to the air source, it controls the first valve to be disconnected from the air source.

[0034] Optionally, the support plate includes: a first support plate and a second support plate;

[0035] The first support plate is fixedly connected to the support base;

[0036] The second support plate is rotatably connected to the outer edge of the first support plate away from the stand, and has an unfolded state and a retracted state relative to the first support plate; in the unfolded state, the surface of the second support plate extends downward at an angle away from the stand, and in the retracted state, the second support plate and the first support plate fold together one above the other.

This invention enables the lifting mechanism and the limiting device to move in tandem. Furthermore, when the limiting device rotates to the first limiting angle, the connection between the power device and the power source is cut off, interrupting the tandem movement of the lifting mechanism and the limiting device. This avoids tedious manual operation and enables efficient and convenient tire lifting. Attached Figure Description

[0073] The technical solutions in 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, not all, of the embodiments of the present invention. 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.

[0074] The terms "first," "second," etc., used in this embodiment of the invention are used to distinguish similar objects, not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, without limiting the number of objects; for example, the first object can be one or more. Furthermore, in this embodiment of the invention, "or" indicates at least one of the connected objects. For example, "A or B" covers three scenarios: Scenario 1: includes A but does not include B; Scenario 2: includes B but does not include A; Scenario 3: includes both A and B. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0075] In the technical solutions of the embodiments of the present invention, terms such as "connection", "coupling" or "connected" are not limited to physical or mechanical connections, but may include electrical connections.

[0076] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0077] This invention provides a tire lifting device, see [link to relevant documentation]. Figure 1 As shown, it includes:

[0078] The base includes: a base 100 and a stand 200 disposed on the base 100;

[0079] The lifting mechanism 1 is mounted on the stand 200 and is used to lift or lower the loaded tires along the length of the stand 200.

[0080] The limiting device 2 is provided on the stand 200 and located on the upper side of the lifting mechanism 1. It can rise or fall along the length of the stand 200 and rotate relative to the stand 200.

[0081] The limiting device 2 and the lifting mechanism 1 are linked together by the linkage mechanism 3. When the lifting mechanism 1 rises, the limiting device 2 is linked to fall, and when the lifting mechanism 1 falls, the limiting device 2 is linked to rise.

[0082] Power unit 4, the power output end is connected to lifting mechanism 1, and power unit 4 is connected to power source through limit device 2;

[0083] The limiting device 2 has a first limiting angle S. When the limiting device 2 rotates to the first limiting angle S, it cuts off the connection between the power device 4 and the power source.

[0084] It should be noted that in practical applications, users can adjust the limit position of tire lifting (i.e., the target height to which the tire needs to be lifted, which can be set by the user according to the tire specifications) by adjusting the limit device 2, which provides high flexibility.

[0085] In this embodiment of the invention, when it is necessary to lift the tire, the user can operate the power unit 4 to drive the lifting mechanism 1 to rise, thereby lifting the tire mounted on the lifting mechanism 1. Simultaneously, the linkage limiting device 2 descends, and the lifting mechanism 1 and the limiting device 2 gradually approach each other. As the tire rises, the tire comes into contact with the limiting device 2. After contact, as the tire rises further until it pushes the limiting device 2 to rotate to the first limiting angle S, the limiting device 2 disconnects the power unit 4 from the power source, causing the power unit 4 to stop driving the lifting mechanism to rise, and the tire is positioned at the limiting position.

[0086] In this embodiment of the invention, the tire lifting device includes: a base, including a base 100 and a stand 200 disposed on the base 100; a lifting mechanism 1, disposed on the stand 200, for loading a tire and lifting or lowering it along the length of the stand 200; a limiting device 2, disposed on the stand 200 and located above the lifting mechanism 1, capable of both lifting or lowering along the length of the stand 200 and rotating relative to the stand 200; the limiting device 2 and the lifting mechanism 1 are linked together by a linkage mechanism 3, wherein when the lifting mechanism 1 rises, it links the limiting device 2 to fall, and when the lifting mechanism 1 falls, it links the limiting device 2 to rise; a power device 4, with its power output end connected to the lifting mechanism 1, and the power device 4 connected to a power source through the limiting device 2; the limiting device 2 has a first limiting angle S, and when the limiting device 2 rotates to the first limiting angle S, it disconnects the power device 4 from the power source. The present invention can realize the linkage movement of the lifting mechanism 1 and the limiting device 2. When the limiting device 2 rotates to the first limiting angle S, the connection between the power device 4 and the power source is cut off, interrupting the linkage movement of the lifting mechanism 1 and the limiting device 2, avoiding tedious manual operation, and can realize tire lifting and lowering efficiently and conveniently.

[0087] In some embodiments of the present invention, see optionally, see Figures 1 to 5 As shown, the linkage mechanism 3 includes:

[0088] There are two pulleys 31, which are arranged one above the other on the stand 200 with their axes parallel to each other.

[0089] The flexible cable 32 is sleeved between two pulleys 31 and has two side sections located between the two pulleys 31 and opposite to each other. One side section is connected to the lifting mechanism 1 and the other side section is connected to the limiting device 2.

[0090] Specifically, see Figures 2 to 5As shown, in some optional embodiments, the lifting mechanism 1 includes a linkage rod 61 extending vertically. The lower end of the linkage rod 61 is connected to the support base 12 of the lifting mechanism 1, and the upper end of the linkage rod 61 is provided with a first clamping member 62. The lifting mechanism 1 is clamped to one side of the flexible cable 32 by the first clamping member 62, and the lifting mechanism 1 is connected to this side. The limiting device 2 includes a second clamping member 7, which is clamped to the other side of the flexible cable 32, and the limiting device 2 is connected to this other side. When the power device 4 drives the lifting mechanism 1 to rise, the lifting mechanism 1 is connected to the flexible cable 32 by the clamping connection of the first clamping member 62, causing the flexible cable 32 to move around the two pulleys 31; the flexible cable 32 is further driven to descend by the clamping connection of the second clamping member 7, thereby realizing that the lifting mechanism 1 descends in conjunction with the limiting device 2 while rising. The principle by which the lifting mechanism 1 moves up in conjunction with the limiting device 2 when it is descending is the same as the principle by which the limiting device 2 moves down, only in the opposite direction, and will not be repeated here.

[0091] In some embodiments of the present invention, the flexible cord 32 may include any of the following: rope, chain, or belt. It should be noted that when the flexible cord 32 is a chain, the two pulleys 31 also have their own circumferentially extending toothed grooves to engage with the chain.

[0092] In some optional embodiments, the lifting mechanism 1 further includes a limiting member 63 for limiting the displacement of the linkage rod 61 in the axial direction of the linkage rod 61 (in this embodiment, i.e., the vertical direction). The limiting member 63 is fixedly disposed on the stand 200 and has a limiting hole extending in the vertical direction. The linkage rod 61 passes through the limiting hole and can slide up and down along the limiting hole.

[0093] In some embodiments of the present invention, see optionally 6 and... Figure 10 As shown,

[0094] The power unit 4 includes: a cylinder 41, and a pneumatic control valve 42 for controlling the extension and retraction of the cylinder 41; the power source is an air source 300.

[0095] See Figures 2 to 7 As shown, the limiting device 2 includes:

[0096] The first guide rail 21 is provided on the stand 200 and extends in the vertical direction;

[0097] The limiting seat 22 is slidably disposed on the first guide rail 21 along the length direction of the first guide rail 21;

[0098] The first valve 23 is located on the limit seat 22, specifically, see [link to details]. Figure 10As shown, the contraction control valve port N of the pneumatic control valve 42 is connected to the air source 300 through the first valve 23. When the contraction control valve port N is connected to the air source 300, the pneumatic control valve 42 controls the cylinder 41 to contract. The first valve 23 is used to control the connection or disconnection between the contraction control valve port N and the air source 300.

[0099] Specifically, in this embodiment of the invention, when the contraction control valve port N is connected to the air source 300, the gas from the air source 300 enters the pneumatic control valve 42 through the air inlet A of the pneumatic control valve 42, and the pneumatic control valve 42 inputs gas from the first exhaust port L to the first air inlet P of the cylinder 41. After the gas enters the cylinder 41, it pushes the cylinder 41 to contract.

[0100] The limiting component 24 is rotatably mounted on the limiting seat 22 and connected to the first valve 23. When the limiting component 24 rotates to the first limiting angle S, it triggers the first valve 23 to control the contraction control valve port N to disconnect from the air source 300.

[0101] It should be noted that, in this embodiment of the invention, the power output end of the power device 4 can be the telescopic arm of the cylinder 41. This telescopic arm is located within the cylinder body cavity of the cylinder 41. Under pneumatic control, the telescopic arm can slide and extend along the extending direction of the cylinder body cavity of the cylinder 41.

[0102] See Figure 8 and Figure 9 As shown, Figure 8 This is a schematic diagram of the limiting component 24 under normal working conditions, wherein the limiting component 24 and the stand 200 form an angle R, and the angle value of the angle R is 0°. Figure 9 This is a schematic diagram of the limiting component 24 under the first limiting angle S, wherein the limiting component 24 and the stand 200 form the first limiting angle S, and the first limiting angle S satisfies: 0° < S < 90°.

[0103] It should be noted that in practical applications, users can precisely design the limiting device to set the target height (i.e., the limiting position) to which the tire needs to be raised when the first limiting angle S is reached, according to their own needs. For details, see [link to relevant documentation]. Figures 7 to 9As shown, the limiting assembly 24 includes: a limiting plate 241 extending in the front-rear direction, with its rear side rotatably mounted on the limiting seat 22 and connected to the first valve 23; and a limiting groove 242 extending vertically on its front side. The limiting assembly 24 also includes: a limiting rod 243, one end of which is detachably disposed in the limiting groove 242. When the target height needs to be adjusted, the user can remove the limiting rod 243 from the limiting groove 242, adjust the connection position of the limiting rod 243 within the limiting groove 242, and then reconnect the limiting rod 243 to the limiting groove 242 to complete the adjustment of the target height. For example, adjusting the connection position upwards increases the target height; adjusting the connection position downwards decreases the target height.

[0104] In some embodiments of the present invention, optionally, the limiting device 2 further includes a first elastic element 25, which is disposed between the limiting component 24 and the limiting seat 22, for providing the limiting component 24 with the elastic force required to maintain normal operating conditions. In some optional embodiments, the first elastic element 25 is a spring.

[0105] In some embodiments of the present invention, see optionally, see Figures 7 to 9 As shown, the first valve 23 includes: a valve body 230, and a first opening 231 disposed in the valve body 230 (i.e., Figure 10 The opening F in the middle and the second opening 232 (that is) Figure 10 The opening G in the valve body 230, and the spring-loaded mechanical switch mechanism 233 provided in the valve body 230;

[0106] The first opening 231 and the second opening 232 are connected through the valve cavity of the valve body 230. The first opening 231 is connected to the air source 300, and the second opening 232 is connected to the contraction control valve port N. The spring-loaded mechanical switch mechanism 233 is used to control the connection and disconnection between the first opening 231 and the second opening 232.

[0107] In this embodiment of the invention, the limiting component 24 (limiting plate 241) is connected to the first valve 23, and the limiting plate 241 abuts against the elastic boss 233a of the spring-loaded mechanical switch mechanism 233.

[0108] Specifically, in the embodiments of the present invention, see Figure 8As shown, under normal operating conditions, the elastic boss 233a of the spring-loaded mechanical switch mechanism 233 is pressed by the limiting component 24 and retracts into the spring-loaded mechanical switch mechanism 233, opening the spring-loaded mechanical switch mechanism 233 and controlling the first opening 231 and the second opening 232 to conduct, so that the contraction control valve port N is connected to the air source 300. The gas from the air source 300 enters the pneumatic control valve 42 through the air inlet A. The pneumatic control valve 42 inputs gas from the first exhaust port L to the first air inlet P of the cylinder 41. After the gas enters the cylinder 41, it pushes the cylinder 41 to contract. The contraction of the cylinder 41 pulls the lifting mechanism 1 to rise. As the lifting mechanism 1 rises, the limiting device 2 descends in conjunction with it, and the lifting mechanism 1 and the limiting device 2 gradually move closer together.

[0109] See Figure 9 As shown, when the limiting component 24 rotates to the first limiting angle S, the elastic boss 233a of the spring-loaded mechanical switch mechanism 233 extends out of the spring-loaded mechanical switch mechanism 233, the spring-loaded mechanical switch mechanism 233 closes, and controls the first opening 231 and the second opening 232 to disconnect, so that the contraction control valve port N is disconnected from the air source 300, the first exhaust port L is disconnected from the first air inlet port P, the cylinder 41 stops contraction movement, the movement of the limiting device 2 and the lifting mechanism 1 stops, that is, the tire reaches the limiting position.

[0110] In some embodiments of the present invention, see optionally, see Figure 1 and Figure 10 As shown, the tire lifting device also includes:

[0111] Manual control valve 5 is located between the first valve 23 and the air source 300, and is used to control the connection or disconnection between the first valve 23 and the air source 300;

[0112] The manual control valve 5 is also connected to the extension control valve port M of the pneumatic control valve 42, and is used to control the connection or disconnection between the extension control valve port M and the air source 300. When the extension control valve port M is connected to the air source 300, the pneumatic control valve 42 controls the cylinder 41 to extend.

[0113] When the manual control valve 5 controls the first valve 23 to be connected to the air source 300, it controls the extension control valve port M to disconnect from the air source 300.

[0114] When the manual control valve 5 controls the extension control valve port M to be connected to the air source 300, it controls the first valve 23 to disconnect from the air source 300.

[0115] See Figure 11aAs shown, when the manual control valve 5 controls the first valve 23 to connect with the air source 300, under normal operating conditions, the spring-loaded mechanical switch mechanism 233 controls the first opening 231 and the second opening 232 to conduct, and the contraction control valve port N is connected to the air source 300. The gas from the air source 300 enters the pneumatic control valve 42 through the air inlet A. The pneumatic control valve 42 inputs gas from the first exhaust port L to the first air inlet P of the cylinder 41. After the gas enters the cylinder 41, it pushes the cylinder 41 to contract. The contraction of the cylinder 41 pulls the lifting mechanism 1 to rise. When the lifting mechanism 1 rises, the linkage limit device 2 descends, and the lifting mechanism 1 and the limit device 2 gradually move closer together. It should be noted that when the manual control valve 5 controls the first valve 23 to connect with the air source 300, that is, the gas from the air source 300 flows through the air inlet A and the exhaust port E of the manual control valve 5, and then enters the first valve 23 through the opening F of the first valve 23. The spring-loaded mechanical switch mechanism 233 controls the first opening 231 and the second opening 232 to be connected, that is, controls the opening F and the opening G of the first valve 23 to be connected.

[0116] See Figure 11b As shown, when the manual control valve 5 controls the first valve 23 to connect with the air source 300, when the limiting component 24 rotates to the first limiting angle S, the spring-loaded mechanical switch mechanism 233 controls the first opening 231 to disconnect from the second opening 232, causing the contraction control valve port N to disconnect from the air source 300, the first exhaust port L to disconnect from the first air inlet port P, the cylinder 41 to stop contraction, and the limiting device 2 and the lifting mechanism 1 to remain relatively stationary, i.e., the limit is reached. It should be noted that, see Figure 11b As shown, when the manual control valve 5 controls the first valve 23 to be connected to the air source 300, that is, the gas from the air source 300 flows through the air inlet A and the air outlet E of the manual control valve 5, and then enters the first valve 23 through the opening F. The spring-loaded mechanical switch mechanism 233 controls the first opening 231 to disconnect from the second opening 232, that is, controls the opening F and opening G of the first valve 23 to disconnect.

[0117] See Figure 11c As shown, when the limiting component 24 rotates to the first limiting angle S, or when it is necessary to increase the distance between the lifting mechanism 1 and the limiting device 2 to load the tire, the user can operate the manual control valve 5 to connect the extension control valve port M to the air source 300. The gas from the air source 300 can flow through the air inlet A and the second exhaust port K of the pneumatic control valve 42, and then enter the cylinder 41 from the second air inlet O, pushing the cylinder 41 to extend. It should be noted that operating the manual control valve 5 to connect the extension control valve port M to the air source 300 means that the gas from the air source 300 flows through the air inlet A and the exhaust port D of the manual control valve 5, and then flows into the extension control valve port M. Figures 11a to 11c In the manual control valve 5, opening B is the exhaust end, which is connected to the outside atmosphere; opening I of the pneumatic control valve 42 is the exhaust end, which is connected to the outside atmosphere.

[0118] In some optional embodiments, the manual control valve 5 has a lever that can be moved up and down. When the user moves the lever up, it controls the first valve 23 to connect with the air source 300; when the user moves the lever down, it controls the extension control valve port M to connect with the air source 300.

[0119] In this embodiment of the invention, the ventilation path design enables efficient and accurate control of cylinder movement, avoiding the problems of complex layout and poor reliability associated with electronic control. The tire lifting device in this embodiment of the invention has high adaptability and high reliability.

[0120] In some embodiments of the present invention, see optionally, see Figure 1 and Figure 6 As shown, the lifting mechanism 1 includes:

[0121] The second guide rail 11 is provided on the stand 200 and extends in the vertical direction;

[0122] The support base 12 is connected to the power output end of the power device 4 and can slide along the second guide rail 11;

[0123] The support plate 13 is connected to the support base 12 and is used to load the tire.

[0124] In some embodiments of the present invention, optionally, the length extension directions of the first guide rail 21 and the second guide rail 11 are parallel to each other.

[0125] It should be noted that the second guide rail 11 is used to limit the displacement of the support seat 12 in the vertical direction, to avoid the movement of the support seat 12 from interfering with other components, and to ensure high transmission efficiency of the support seat 12, thereby ensuring high reliability of the tire lifting device.

[0126] In this embodiment of the invention, the lifting mechanism 1 includes a second guide rail 11, a support base 12, and a support plate 13, which helps to ensure the high reliability of the tire lifting device.

[0127] In some embodiments of the present invention, see optionally, see Figure 1 and Figure 12 As shown, the support plate 13 includes: a first support plate 131 and a second support plate 132;

[0128] The first support plate 131 is fixedly connected to the support base 12;

[0129] The second support plate 132 is rotatably connected to the outer edge of the first support plate 131 away from the stand 200, and has an unfolded state and a retracted state relative to the first support plate 131; in the unfolded state, the surface of the second support plate 132 extends downward in the direction away from the stand 200; in the retracted state, the second support plate 132 and the first support plate 131 move closer together and fold inward.

[0130] In practical applications, during the process of loading the tire onto the support plate 13, the user can switch the second support plate 132 to the unfolded state. Then, the user can push the tire along the inclined surface of the second support plate 132 onto the first support plate 131. After the tire lifting device is used, the user can switch the second support plate 132 to the retracted state, reducing the volume occupied by the tire lifting device.

[0131] In some embodiments of the present invention, see optionally, see Figure 1 and Figure 13 As shown, the base 100 includes:

[0132] The frame 101 is provided with a third guide rail 102 extending in the left and right direction;

[0133] The movable base 103 is mounted on the frame 101 and can slide along the third guide rail 102. The upright base 200 is mounted on the movable base 103.

[0134] In this embodiment of the invention, the base 100 includes: a frame 101, on which a third guide rail 102 extending in the left-right direction is provided; a movable seat 103, which is disposed on the frame 101 and can slide along the third guide rail 102; and a stand 200 disposed on the movable seat 103, which can realize the displacement of the loaded tire in the left-right direction and improve the flexibility of the loading and unloading of the loaded tire.

[0135] In some embodiments of the present invention, see optionally, see Figure 1 and Figure 13 As shown, the third guide rail 102 includes at least two parallel tracks 102a. In some alternative embodiments, the tracks 102a are linear tracks.

[0136] This invention also provides a tire inspection device, including any of the tire lifting devices described in this invention.

[0137] In some embodiments of the present invention, see optionally, see Figures 14 to 17 As shown, the tire inspection equipment may also include a tire balancing device 400.

[0138] Specifically, see Figure 14As shown, the user operates the tire lifting device to lift the tire to the limit position, that is, the limit device 2 rotates to the first limit angle S. At this time, the tire is aligned with the tire loading shaft of the tire balancing device 400. Furthermore, the tire lifting device slides along the third guide rail 102 via the movable seat 103 to push the tire into the tire loading shaft of the tire balancing device 400.

[0139] See afterward. Figure 15 As shown, by sliding the movable seat 103 along the third guide rail 102, the user operates the tire lifting device away from the tire balancing device 400 to avoid interfering with the user's tire balancing calibration operation using the tire balancing device 400.

[0140] See Figure 16 As shown, after the balancing calibration is completed, the user operates the tire lifting device to approach the tire balancing device 400 via the sliding seat 103 along the third guide rail 102, until the tire is positioned between the lifting mechanism 1 and the limiting device 2. Then, the user manipulates the lifting mechanism 1 to rise, and the limiting device 2 to fall in conjunction with it, until the tire pushes the limiting device 2 to rotate to the first limiting angle S. At this point, the lifting mechanism 1 and the limiting device 2 stop moving, and the tire lifting device completes the tire loading.

[0141] See Figure 17 As shown, the user operates the tire lifting device to push the tire that has completed the balance calibration operation away from the tire balancing device 400.
