detailed description

The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the jack of the disassembling tire of the present invention comprises a vertical frame 1 having a column 2, and the vertical frame 1 is provided with a lifting mechanism 3 which is movable up and down along the column 2 The outer end of the lifting mechanism 3 is provided with a rim positioning mechanism 4 parallel to the column 2, and the upper side of the column 2 is provided with a tire outer rim upper bar 5 that can cooperate with the rim positioning mechanism 4.

The rim positioning mechanism 4 is composed of an L-shaped shaft 4-1 and a rim disc-shaped cartridge 4-2 connected to the upper end of the L-shaped shaft 4-1. The horizontal shaft portion 4-1-1 of the L-shaped shaft is rotatably coupled to the connection end of the elevating mechanism 3, and is provided with a rotational connection positioning mechanism 4-3. The upper side of the vertical frame 1 is provided with a hook piece 6 for pulling the retaining ring of the tire 8. The hook piece 6 is provided with a slit 6-1 for engaging the retaining ring, and is connected to the vertical seat via the connecting piece 7 The upper side of the frame 1 is connected.

The vertical frame 1 is provided with a beam 9. The beam 9 is provided with a lever mechanism 11 driven by a cylinder or cylinder 10 for supporting the inner edge of the tire 8 and for assembling with the rim.

The above-mentioned lever mechanism 11 is a slider 11-2 which is slidable relative to the beam 9 and driven by the cylinder or the piston rod 11-1 of the cylinder 10, and a lever 11-3 whose upper end is hinged to the side end of the carriage 11-2. And two intercepting links 11-4 hinged to the other side of the lever 11-3 and the slider 11-2 are connected.

An L-shaped hook 13 for hooking the toe of the inner edge of the tire 8 is attached to the slider 11-2 via the chain 12.

The lifting mechanism 3 includes a lifting carriage 3-2 driven by a vertical cylinder or cylinder 3-1 provided in the column, a lifting rack 3-3 provided on the carriage 3-2, and a rack for driving the rack 3-3 is composed of a rack-and-pin drive cylinder or cylinder 3-4, and the rack 3-3 drives the rim positioning mechanism 4 via a gear 3-5 connected to the horizontal shaft portion 4-1-1 of the L-shaped shaft. The longitudinal plane rotates.

The upper bar 5 is rotatable along a horizontal plane, and the inner end thereof is hinged to the column 2.

The above-mentioned stopper bar includes upper and lower stopper bars 5, 14 which are respectively located on the upper side and the lower side of the column 1.

The working principle of the present invention is achieved as follows: When disassembling the high-pressure tire with the inner tube, firstly, the rim positioning mechanism is rotated from the horizontal position by 9 Q to the vertical position, and then the tire to be disassembled is mounted on the rim positioning mechanism and locked. Next, re-rotate the rim positioning mechanism back to 9 Q to the horizontal position, and raise the lifting slide so that the lever of the lever mechanism is placed on the tire casing, so that the retaining ring sleeved on the outer ring of the rim protrudes, with the seam The hook piece of the mouth hooks the retaining ring, then lowers the lifting slide, and finally the retaining ring is separated from the rim, and then the upper bar is rotated to the working plane of the tire, and the height of the rim positioning mechanism is higher than that of the upper bar The height rises and lowers the slide seat, so that the lever of the lever mechanism is placed on the tire casing, and then the L-shaped hook is placed in the space formed by the plunger to squeeze the tire casing, and then the lifting slider is lowered, due to the pulling effect of the L-shaped hook, The upper ring of the tire is separated from the rim, and the upper ring of the tire is pressed against the lower ring of the tire through the upper bar, so that the lower ring of the tire is also separated from the rim, thereby achieving the purpose of getting rid of the tire. When it is applied to a low-pressure tire equipped with a tube, the tire fixing process is the same as that of a high-pressure tire, but it does not need to be separated from the retaining ring process, but only the lifting and lowering slide, so that the lever of the lever mechanism is placed on the tire casing, and then the L-shaped hook is placed. In the space formed by the plunger to squeeze the tire, and then the lifting slider is lowered, the upper ring of the tire is separated from the rim by the pulling action of the L-shaped hook, and the tire can be completely detached from the rim by manpower. When the vacuum tire is removed, the tire fixing process is the same as the high pressure tire. Next, the lifting slide is raised, the lever of the lever mechanism is placed on the tire, and the L-shaped hook is placed in the space formed by the tire to squeeze the tire. Then, the lifting slide is lowered, and the upper ring of the tire is separated from the rim by the pulling action of the L-shaped hook, and then the rack is placed on the lifting mechanism. The driving cylinder or the cylinder drives the rack to rise, and the rack drives the gear matched thereto, since the gear is connected with the horizontal shaft portion of the L-shaped shaft of the rim positioning mechanism, thereby driving the rim positioning mechanism to rotate 180 degrees along the longitudinal plane, causing the tire to be reversed Then, the lower bar is rotated to the working plane of the tire, the height of the lower bar is higher than the height of the tire, and then the lifting carriage is raised, so that the upper bar blocks the tire from ascending and disengages from the rim.

When installing the tire, first position the rim, place one side of the tire on the outer ring of the rim, and place the other side on the upper surface of the rim, and at the same time adjust the lateral position of the lever of the toggle mechanism through the slide driven by the cylinder or cylinder. , so that it falls into the inner ring of the tire casing, and then moves outward through the sliding rod driven by the cylinder or cylinder, so that the outer tube expands outward, so that the inner ring of the tire reaches the outer diameter of the rim, due to the rim The inner edge of the tire is coated with a lubricant. After the tire is expanded, it will be directly drawn into the outer ring of the rim, so that the rim is completely placed under the package of the tire, and finally the purpose of installing the tire is achieved.

The above are only the preferred embodiments of the present invention, and all changes and modifications made by the scope of the present invention should be construed as the scope of the present invention.
