[0038] Since manually installing tires increases the installation stress, this invention provides a transport trolley to support the tires and reduce the installation stress.

[0039] This utility model embodiment provides a transport trolley for transporting tires, such as... Figures 1 to 3 As shown, the transport trolley includes a movable support 1, a support frame 2, and a drive structure 3. The support frame 2 is slidably connected to the movable support 1. The support frame 2 includes a first baffle 21 and at least two support components 22. The first baffle 21 and the movable support 1 are arranged opposite to each other. The support components 22 are connected between the first baffle 21 and the movable support 1 and are spaced apart. The area enclosed by the first baffle 21, the support components 22, and the movable support 1 is used to hold vertically placed tires 100. The drive structure 3 is connected to the support frame 2 to drive the support frame 2 to slide along the vertical direction of the movable support 1.

[0040] Because the support frame 2 is driven by the drive structure 3 to slide vertically on the movable bracket 1, the installer can place the tire 100 at a lower position on the trolley. In addition, the tire 100 is placed vertically on the support frame 2, so that the tire 100 is facing the vehicle body. After the drive structure 3 is controlled to lift the tire 100 to the installation position, the tire 100 is installed on the vehicle body by the transport trolley. Then the support frame 2 is lowered and detached from the tire 100, thereby reducing the workload of the installer. In addition, the first baffle 21, the support component 22 and the movable bracket 1 cooperate with each other to limit the tire 100, which can prevent the tire 100 from falling off the support frame 2.

[0041] Specifically, the movable bracket 1 and the first baffle 21 can limit the front and rear sides of the tire 100, while at least two support components 22 work together to support the tire 100, and the tire 100 is supported and limited by the support components 22 in the circumferential direction.

[0042] In some embodiments, the support assembly 22 includes a support shaft 221 and a roller 222. The roller 222 is sleeved on the support shaft 221 and can rotate relative to the support shaft 221. The support shaft 221 is connected to the first baffle 21 and the movable bracket 1, respectively. When moving the tire 100 into the transport trolley, after the tire 100 contacts the support assembly 22, the tire 100 can be released first. Since the roller 222 is sleeved on the support shaft 221 and can rotate relative to the support shaft 221, the tire 100 will slide towards the area enclosed by the first baffle 21, the support assembly 22, and the movable bracket 1, or slide in the opposite direction to this area, thus facilitating the handling and placement of the tire 100. In addition, the friction between the tire 100 and the support assembly 22 is also rolling friction, which can reduce the friction between the tire 100 and the support assembly 22 and avoid excessive friction between the support assembly 22 and the tire 100 during installation, thus preventing tire 100 wear.

[0043] Furthermore, the rotation of the roller 222 relative to the support shaft 221 facilitates the adjustment of the tire 100's position. When the tire 100 needs to be aligned with the vehicle body during installation, the tire 100 can be lifted up first, then rotated appropriately to a suitable position before resting it against the roller 222. The rotation of the roller 222 will adjust the position of the tire 100 so that it is located within the area enclosed by at least two support components 22. The vertical position of the tire 100 can be adjusted by lifting the support frame 2 as a whole. After the installation position is adjusted, the tire 100 is pushed horizontally into the bottom of the vehicle body for installation, which reduces the risk of the wheel rim being damaged.

[0044] Specifically, to ensure smoother rotation of the roller 222, the support assembly 22 also includes a bearing, which is positioned between the roller 222 and the support shaft 221. The inner ring of the bearing is in contact with the outer peripheral wall of the support shaft 221, and the outer ring of the bearing is in contact with the inner peripheral wall of the roller 222. This ensures a secure connection between the roller 222 and the support shaft 221 via the bearing, and also ensures that the support assembly 22 rotates relative to the tire 100.

[0045] Furthermore, in order to reduce the friction between the roller 222 and the tire 100, in some embodiments a rubber sleeve is provided on the outer periphery of the roller 222. The rubber sleeve can reduce the friction between the tire 100 and the roller 222, thereby protecting the tire 100.

[0046] Of course, in some other embodiments, the support component 22 includes a support shaft 221, which connects the first baffle 21 and the movable bracket 1, and the support shaft 221 provides support for the tire 100.

[0047] In order to ensure the limiting of the tire 100 and make the tire 100 more stable during movement, in some embodiments the support component 22 is arranged in parallel between the movable bracket 1 and the first baffle 21, and the two support components 22 are set at the same height, allowing for installation errors. This ensures that the tire 100 is supported at the same position on both sides, avoiding the tire 100 from tilting and separating from the support frame 2 due to one support position being higher or lower.

[0048] In some embodiments, such as Figure 3 and Figure 4 As shown, the support frame 2 also includes a connector 23, which is slidably connected to the movable bracket 1 and fixedly connected to the support assembly 22. The drive structure 3 is connected to the connector 23 to drive the connector 23 to slide along the vertical direction of the movable bracket 1. The connector 23 is used to connect the support assembly 22 to the movable bracket 1, thus enabling at least two support assemblies 22 to be driven by the drive structure 3 simultaneously. For example, the connector 23 is fixedly connected to the support assembly 22 by bolts.

[0049] like Figure 2 and Figure 3 As shown, for example, the movable bracket 1 and the connector 23 are slidably connected via the guide rail 4 and the slider 5. The movable bracket 1 is used to fix the guide rail 4, while the connector 23 is used to fix and connect the slider 5. The slider 5 is slidably connected to the guide rail 4 and can move relative to the guide rail 4. The extension direction of the guide rail 4 is in the same direction as the vertical direction. Through the cooperation of the guide rail 4 and the slider 5, the support frame 2 can be raised and lowered smoothly.

[0050] In some embodiments, the support frame 2 further includes a second baffle 24, which is fixedly connected to the connector 23 and the support assembly 22 respectively. The second baffle 24 is disposed between the support assembly 22 and the connector 23. The second baffle 24, together with the first baffle 21, allows the tire 100 to be vertically positioned without contacting the connector 23. This prevents the tire 100 from shaking during movement and causing large-area contact with the connector 23, thus protecting the tire 100. The width of the second baffle 24 is greater than the width of the connector 23, which increases the distance between the support assemblies 22 located on both sides of the tire 100. The support assemblies 22, which are positioned opposite each other, can be installed at an appropriate distance from the second baffle 24 to meet the support needs of tires 100 of different models and diameters. In addition, the structure of the connector 23 can be more compact, reducing the manufacturing cost of the transport trolley.

[0051] In some other embodiments, the top surface of the second baffle 24 is higher than the top surface of the first baffle 21. In order to facilitate the quick separation of the first baffle 21 from the tire 100, the height of the first baffle 21 should be minimized.

[0052] To facilitate the installation of the tire 100 on the axle of the vehicle body, the top of both the second baffle 24 and the first baffle 21 are provided with grooves 211. The grooves 211 can fully expose the wheel hub of the tire 100 and prevent the first baffle 21 and the second baffle 24 from interfering with the wheel hub respectively. This allows the axle to be inserted into the tire 100 after the tire 100 is pushed towards the axle. After the tire 100 is fitted onto the axle, bolts are inserted into the tire 100 through the grooves 211 provided on the second baffle 24. Then, the support frame 2 is lowered to separate from the tire 100, thereby separating the support frame 2 from the tire 100 and reducing the installation strength of the tire 100.

[0053] In order to facilitate fine-tuning and movement of the entire transport trolley, in some embodiments a grip handle 25 is provided on the top of the connector 23. Specifically, the grip handle 25 is fixed on both sides of the top of the connector 23, which facilitates the movement of the entire transport trolley.

[0054] In some embodiments, the transport trolley further includes a limiting component for limiting the travel of the support frame 2, the limiting component being disposed on the movable bracket 1. The limiting component can prevent the guide rail 4 and the slider 5 from disengaging when the support frame 2 rises or falls with the drive structure 3, thereby limiting the support frame 2. In addition, the limiting component can also limit the travel of the support frame 2 to prevent the tire 100 from being raised too high or too low.

[0055] In some embodiments, the limiting assembly includes a first limiting member 6 and a second limiting member 7, both of which are fixedly installed on the movable bracket 1. Vertically, the first limiting member 6 and the second limiting member 7 are respectively installed on both sides of the support frame 2. Thus, the first limiting member 6 and the second limiting member 7 cooperate to limit the travel of the support frame 2, preventing connection failure between the support frame 2 and the movable bracket 1.

[0056] For example, both the first limiting member 6 and the second limiting member 7 are stops, which are fixed to the movable bracket 1 by screws. In some other embodiments, both the first limiting member 6 and the second limiting member 7 are limit switches.

[0057] In some embodiments, the transport trolley further includes a material box bracket 8, which is fixedly installed on the side of the movable bracket 1 away from the support frame 2. The material box bracket 8 is used to hold material boxes 81. The material boxes 81 are used to hold tools, such as wrenches, screwdrivers, bolts, etc., which facilitates the unified storage of tools, avoids installation personnel from placing them randomly, and also makes it easier for installation personnel to fix the tires 100 in a timely manner.

[0058] In some embodiments, the transport trolley further includes a handle 9, which is fixedly installed on the side of the movable bracket 1 opposite to the support frame 2. The handle 9 is designed to facilitate hand gripping and pushing / pulling of the transport trolley.

[0059] Specifically, such as Figure 1 and Figure 3 As shown, the movable support 1 includes a support body 11, a base 12, and casters 13 disposed at the bottom of the base 12. The support body 11 is fixedly mounted on the top of the base 12. The support frame 2 is slidably connected to the support body 11. The drive structure 3 is disposed above the base 12, and the base 12 provides support for the drive structure 3. Specifically, the drive structure 3 is supported by a drive structure mounting plate 10 fixed on the base 12. The casters 13 allow the tire 100 to be transported from a distance to the installation station.

[0060] There are multiple casters 13. In order to enable the emergency stop of the transport trolley, at least one of the casters 13 is a self-locking caster. For example, the bottom of the base 12 is rotatably equipped with several casters 13. Among the two casters 13 near the push side, at least one caster 13 is equipped with a foot brake, that is, at least one caster 13 is a self-locking caster. The emergency stop of the transport trolley is controlled by stepping on the foot brake.

[0061] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
