[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Example 1:

[0039] like Figure 1-2 The figure shown is a tire mounting head provided in this embodiment, including a disassembly device 1, an installation device 2, a fixing device 3, and a resetting device 4;

[0040] The disassembly device 1 has a tire removal hook 13, which can extend between the rim 5 and the tire bead 61 of the tire 6 and hook up the tire bead to separate the tire 6 from the rim 5.

[0041] The mounting device 2 includes a mounting part 21 and a hinge part 22 connected to the mounting part 21. The hinge part 22 and the connecting part 12 are hinged together. The mounting part 21 can be rotated from the initial position to the working position. The fixing device 3 can fix the vertical mounting part 21 to one side of the disassembly part 11. After fixing, the mounting part 21 can extend to the space between the rim 5 and the tire bead, so that a gap is created between the rim 5 and the tire bead. The pressure plate extends to the gap and presses the tire 6 down onto the rim 5.

[0042] The reset device 4 is connected to the mounting device 2 and can drive the mounting device 2 to rotate to the initial position;

[0043] When removing tire 6, the linear drive unit drives the tire removal hook 13 to a suitable position, and then the tire pressure block presses down on the tire to create a gap between the tire bead and the rim. Figure 5 As shown, the lifting drive device drives the tire removal hook 13 of the disassembly device 1 to descend through the gap to the lower side of the upper tire bead and hook the upper tire bead. Then, driven by the lifting drive device, the tire removal hook 13 rises and hooks the upper tire bead to the upper side of the rim 5 flange. With the rotation of the tire 6, the upper tire bead of the tire 6 is completely pulled to the upper side of the rim 5 flange. Finally, the lower tire removal plate moves upward to lift the lower tire bead, so that the lower tire bead is placed on the upper side of the rim 5 flange, and the tire 6 is removed.

[0044] When installing tire 6, the linear drive device drives the tire removal hook 13 to a suitable position, then rotates the mounting device 2 to make the mounting part 21 vertical, and uses the fixing device 3 to fix its position (the mounting device 2 is fixed to the removal device 1). Figure 6As shown, the lifting drive device drives the mounting part 21 to move downwards and insert it between the rim 5 and the tire 6. The linear drive device drives the mounting device 2 (together with the disassembly device 1) to move radially outwards. The mounting part 21 increases the gap between the rim 5 and the tire 6, facilitating the insertion of the upper tire bead into the gap, so as to press the upper tire bead against the lower side of the upper flange of the rim 5. Figure 7 As shown, the installation of tire 6 and rim 5 is now complete;

[0045] In order to facilitate the removal of the next car tire to be removed by the disassembly device 1, after the fastening of the fixing device 3 is released, the mounting device 2, driven by the reset device 4, rotates away from the disassembly device 1 around its hinge position with the disassembly device 1, so that the mounting device 2 rotates from the vertical position to the initial position, making way for the use of the disassembly device 1.

[0046] This utility model of a tire removal and installation head has both a removal device 1 and an installation device 2. When it is necessary to remove the tire 6, the installation device 2 is set to the initial position, and the removal hook of the removal device 1 is used to separate the tire 6 from the rim 5. When it is necessary to install the tire 6, it is only necessary to rotate the installation device 2 so that the installation part 21 is in a vertical position and the installation part 21 extends between the tire 6 and the rim 5, which facilitates the insertion of the tire plate and the installation of the tire 6 on the rim 5. The operation of this tire removal and installation head is very convenient and can greatly improve the installation efficiency.

[0047] In a specific embodiment, such as Figure 1-4 As shown, the disassembly device 1 includes a disassembly part 11 and a connecting part 12 that is angularly connected to the disassembly part 11, and a tire removal hook 13 is provided at the bottom of the disassembly part 11; the mounting part 21 is a straight plate structure, and the mounting part 21 is angularly connected to the hinge part 22.

[0048] The hinge portion 22 is located on the upper side of the mounting portion 21; the angle between the mounting portion 21 and the hinge portion 22 is equal to the angle between the connecting portion 12 and the disassembly portion 11, so that when the mounting portion 21 is rotated to the working position, the bottom surface of the hinge portion is in contact with the top surface of the connecting portion 12; the connection portion can ensure the positional stability of the mounting device.

[0049] When it is necessary to install the tire 6 on the rim 5, the mounting part 21 of the mounting device 2 is manually driven to rotate, so that the bottom surface of the hinge part 22 is in contact with the top surface of the connecting part 12. At this time, the mounting part 21 is rotated to a vertical position. Since the mounting part 21 is a straight plate structure, after rotating the mounting part to a vertical position, it is driven to descend by the lifting drive device and extend between the rim 5 and the tire 6. Under the drive of the linear movement device, it moves radially outward, increasing the gap between the rim 5 and the tire 6. This makes it easier for the tire bead of the tire to be pressed down to the lower side of the flange of the rim 5 by the extension of the pressure plate into the gap, thus realizing the installation of the rubber tire.

[0050] In a specific embodiment, such as Figure 2 As shown, the fixing device 3 includes a fixing part 31 and a bolt 32;

[0051] The fixing part 31 is provided on one side of the mounting device 2, and the fixing part 31 is provided with a threaded hole, and the bolt 32 is provided at the threaded hole;

[0052] When the hinge 22 rotates to fit against the connecting part 12, the mounting part 21 is in a vertical position, the side wall of the fixing part 31 fits against the side wall of the disassembly part 11, and the bolt 32 is rotated so that one end of the bolt 32 abuts against the side wall of the disassembly part 11, thus fixing the mounting device 2 to the disassembly device 1; when it is necessary to install the tire 6, after the tire 6 is placed on the upper side of the rim 5, the external force drives the mounting device 2 to rotate around its hinge with the disassembly device 1, so that when the hinge 22 abuts against the top surface of the connecting part 12, the mounting part 21 rotates to a vertical state, the side wall of the fixing part 31 fits against the side wall of the mounting part 21, and the bolt 32 is rotated so that one end of the bolt 32 abuts against the side wall of the mounting part 21, thus locking the mounting device 2 to the disassembly device 1, so that the mounting part 21 can extend between the tire 6 and the rim 5, which facilitates the installation of the tire 6 and the rim 5 and improves the reliability of the installation;

[0053] When it is necessary to remove the next car tire, loosen bolt 32. Under the pull of reset device 4, mounting device 2 rotates upward around the hinge position with the disassembly device, so that the mounting part moves away from the disassembly device 1. Mounting device 2 resets so that disassembly device 1 can remove the next car tire.

[0054] In a specific embodiment, such as Figure 1 As shown, the reset device 4 includes a tension spring 41 and a tension spring fixing plate 42; the tension spring fixing plate 42 is fixed on the cross arm 7 located on one side of the disassembly device 1, one end of the tension spring 41 is connected to the tension spring fixing plate 42, and the other end of the tension spring 41 is connected to the hinge part 22; when the installation device 2 is used up, the bolt 32 is loosened, and the installation device 2 can move away from the disassembly device 1 under the pull of the tension spring, so as to avoid positional interference with the disassembly device 1 and avoid affecting the use of the disassembly device 1.

[0055] In a specific embodiment, the cross arm is connected to a linear drive device, which is mounted on the lifting drive device; both the linear drive device and the lifting drive device are cylinders. The linear drive device is used to drive the disassembly device and the installation device to move linearly, and the lifting drive device is used to drive the disassembly device and the installation device to move up and down.

[0056] In a specific embodiment, the connecting part 12 is provided with a mounting hole at one end away from the disassembly part 11, and the hinge part 22 is provided with a connecting hole at one end away from the mounting part 21. The connecting pin passes through the mounting hole and the connecting hole to connect the mounting device 2 and the disassembly device 1, so as to realize the hinge between the mounting device 2 and the disassembly device 1, which facilitates driving the mounting device 2 to a vertical state or to a reset state, improves the efficiency and convenience of switching the position of the mounting device 2, and improves the disassembly and assembly efficiency of the tire 6 and the rim 5.

[0058] A tire changing machine has a tire changing head as described in this solution, and the working process of the tire changing head is as described in Example 1.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
