Description

Technical Field

[0001] The utility model relates to the technical field of heavy truck production, in particular to a tire installation hanger for a heavy truck production line. Background Art

[0002] Heavy truck is the abbreviation of heavy truck. It is an authentic, traditional and informal name for heavy trucks and semi-trailer tractors, including various special vehicles (sprinklers, fire trucks, road cleaning trucks, tank trucks, mixer trucks, etc.), dump trucks (earth-moving trucks, all with lifts), trucks (for transporting goods, including livestock) and some rare off-road vehicles that we see on the road. Some existing heavy trucks need to install tires during the production process, and the tires are heavy, so hoists are needed to move the tires.

[0003] Some existing tire hoists can move the tire after clamping it when in use, but some hoists use steel wire ropes for lifting. Although the steel wire ropes are strong, they are relatively soft. When the tire is moved, the tire will swing, which makes the tire unstable when moving. Not only is the tire prone to falling, but it also affects the safety of tire installation.

[0004] At the same time, when the tire is installed, the tire and the wheel hub need to be hoisted, and the existing hoisting device can only hoist the tire or the wheel hub when in use. The hoisted tire or wheel hub can only be replaced by replacing the hoisting device, which leads to the poor applicability of the existing hoisting device, which is not only inconvenient, but also affects the installation efficiency of the tire.

Under the action of the winding roller, the steel wire rope can be wound up, so as to facilitate the adjustment of the position of the tire. One end of the steel wire rope of the lifting mechanism 2 is fixedly connected to a fixing frame 3, and an electric telescopic rod 4 is bolted to the top of the fixing frame 3. The output shaft of the electric telescopic rod 4 penetrates into the interior of the fixing frame 3 and is movably connected to the inner wall of the penetration point, and the output shaft of the electric telescopic rod 4 is hinged with a movable rod 5. There are three movable rods 5, and they are all distributed in a circular array with the center point of the electric telescopic rod 4. Under this action, the tire can be clamped from three directions, so that the device is more stable when clamping the tire. A positioning frame 6 is fixedly connected to the lower part of the inner cavity of the fixed frame 3. The positioning frame 6 is a Y-shaped structure design, and the positioning frame 6 is used in conjunction with the movable rod 5. The surface of the positioning frame 6 is slidably connected with a movable sleeve 7. The top of the movable sleeve 7 and the bottom of the movable rod 5 are hinged to each other, and the bottom of the movable sleeve 7 is fixedly connected with a connecting plate 8. Under this action, the movable rod 5 and the positioning frame 6 can cooperate with each other to move the movable sleeve 7 through the electric telescopic rod 4, and several movable sleeves 7 can be moved at the same time, which is more convenient.

Under the action of the positioning mechanism 9, the surface of the wheel hub can be squeezed to clamp the wheel hub. The other side of the connecting plate 8 is fixedly connected to a limiting block 10. The limiting block 10 is designed in an arc structure. The limiting block 10 is made of rubber and can be opened in the opposite direction under this action, so that the tire can be opened normally, thereby facilitating the movement of the tire. A fixing shell 11 is provided on one side of the top of the mounting frame 1. The other end of the fixing shell 11 penetrates the bottom of the mounting frame 1 and is slidably connected to the inner wall of the penetration point. The fixing shell 11 is designed in a T-shaped structure. Under this action, the fixing shell 11 will not easily detach from the surface of the mounting frame 1. The inner wall of the fixing shell 11 is slidably connected to a guide The guide rod 12 is provided with a connecting mechanism 13 at the bottom thereof, and the connecting mechanism 13 can connect the guide rod 12 and the fixing frame 3, so that the fixing frame 3 will not swing when the lifting mechanism 2 is lifted or lowered, effectively improving the stability of the fixing frame 3 during movement, and also improving the stability of the tire and the wheel hub during movement. Guide blocks 14 are fixedly connected to both sides of the inner cavity of the fixing shell 11, and guide grooves 15 are provided on both sides of the guide rod 12. The inner wall of the guide groove 15 is slidably connected to the surface of the guide block 14. Under this action, when the guide rod 12 moves, the guide block 14 and the guide groove 15 cooperate to guide the guide rod 12, so that the guide rod 12 can be more stable during movement.

[0024] The positioning mechanism 9 includes a mounting groove 91 provided on one side of the connecting plate 8. The cross-section of the inner cavity of the mounting groove 91 is a T-shaped structure design. The inner cavity of the mounting groove 91 is slidably connected with a connecting block 92.

The positioning plate 93 is designed in an arc shape, which facilitates the clamping and fixing of the wheel hub. A rotating groove 94 is provided on the surface of the mounting groove 91. Under this action, when the tire is moved using the limit block 10, the connecting block 92 can be moved to the rotating groove 94 through the positioning plate 93, and then the positioning plate 93 and the connecting block 92 are rotated to reduce the space occupied by the positioning plate 93. Then, the positioning plate 93 is limited under the cooperation of the connecting block 92 and the mounting groove 91, so that it will not rotate easily, which is more convenient.

[0025] The connecting mechanism 13 includes a fixed ring 131, the bottom of which is fixedly connected to the top of the fixed frame 3, a movable groove 132 is provided on the top of the fixed ring 131, the cross-sectional shape of the movable groove 132 is a T-shaped structure design, the inner wall of the movable groove 132 is slidably connected with a movable block 133, the top of the movable block 133 is fixedly connected to the bottom of the guide rod 12, under this action, when the fixed frame 3 needs to be rotated, the cooperation of the movable block 133 and the movable groove 132 will not affect the guidance of the fixed shell 11 and the guide rod 12 to the fixed frame 3, thereby making the sling more convenient to use.

[0026] It is worth noting that the technical features such as the mounting frame 1 and the lifting mechanism 2 proposed in this technical solution should be regarded as the prior art. The specific structure, working principle, and possible control method and spatial arrangement method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: First, when the wheel hub needs to be moved, the staff moves the positioning plate 93 to the surface of the wheel hub through the cooperation of the mounting frame 1 and the lifting mechanism 2, and then turns on the electric telescopic rod 4. Under the action of the electric telescopic rod 4, the movable sleeve 7 drives the connecting plate 8 to move through the movable rod 5. Under this action, the connecting plate 8 drives the positioning plate 93 to move through the cooperation of the mounting groove 91 and the connecting block 92, so that the positioning plate 93 clamps the wheel hub, and then turns on the lifting mechanism 2 to drive the wheel hub to move through the cooperation of the fixing frame 3. When the fixing frame 3 moves, it will guide the fixing frame 3 through the cooperation of the fixing shell 11 and the guide rod 12, so that the fixing frame 3 can be more stable when moving, and with the cooperation of the connecting mechanism 13, the wheel hub can be easily rotated at various angles. After the wheel hub is moved to a suitable position, the limit of the wheel hub is released. When the tire needs to be moved, the positioning plate 93 is pushed to move the connecting block 92 to the rotating groove 94, and then the positioning plate 93 is rotated ninety degrees, so that the positioning plate 93 can stand up to reduce the space occupied by it, and then the limit block 10 is put into the inside of the tire, and then the limit block 10 is moved outward under the action of the electric telescopic rod 4 to fix the tire, and then the tire is moved to a suitable position through the cooperation of the mounting frame 1 and the lifting mechanism 2.
