Description

Technical Field

[0001] This utility model relates to the field of tire flipping technology, specifically a tire flipping frame. Background Technology

[0002] When repairing car tires, the tires need to be lifted up, and to facilitate the repair, they are often flipped over, which requires the use of a tire flipping frame.

[0003] Patent document CN212709333U discloses a car tire flipping device, including an anti-slip plate. A sliding component is fixedly installed on the upper end of the anti-slip plate. A housing is fixedly installed on the upper left side of the sliding component. A control box is fixedly installed on the upper front of the housing. A rotating device is fixedly installed inside the housing. A fixed plate is slidably connected to the upper end of the sliding component. A bearing seat is fixedly installed in the middle of the left end of the fixed plate. A support rod is movably installed in the middle of the left end of the bearing seat. Clamping devices are fixedly installed on the left end of the support rod and the right end of the rotating device. This car tire flipping device allows the fixed plate to slide within a slide rail and be fixed using a fastening knob, thereby adjusting the distance between the two clamping devices. This makes it widely applicable and conducive to large-scale promotion. The installation of a pressure sensor, control box, and cylinder prevents damage to the tire due to excessive clamping force during clamping. However, the existing technology still has shortcomings:

[0004] (1) The height of the clamping device used to clamp the tire in the prior art is fixed. The larger the tire size, the more space is needed when flipping. Therefore, the height of the clamping device cannot be adjusted, which reduces the applicability of the device. At the same time, the weight of the tire is generally large. The clamping device with a fixed height will make it inconvenient to place the tire, which is time-consuming and laborious, and reduces work efficiency.

[0005] (2) In the prior art, the two sides of the device rotate through a pivot or support rod when flipping, which can easily reduce the service life of the device. At the same time, the excessive weight of the tires can make it difficult for the clamping frame to rotate, which also reduces work efficiency. Utility Model Content

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0043] like Figures 1 to 6 As shown, this embodiment proposes a tire flipping frame, including a base plate 1. A rectangular groove 11 is provided on the top of the base plate 1. A movable structure 2 is provided in the rectangular groove 11. Two uprights 3 are symmetrically arranged on both sides of the top of the rectangular groove 11. A rectangular through hole is provided in the middle of the uprights 3. The movable structure 2 includes a bidirectional lead screw 21 rotatably connected to both sides of the inner wall of the rectangular groove 11. A motor 22 is fixedly installed on one side of the base plate 1. The output end of the motor 22 is fixedly connected to one end of the bidirectional lead screw 21. The threaded portions on both sides of the bidirectional lead screw 21 are threadedly connected to sliders 23. The uprights 3 are fixedly connected to the top of the sliders 23. By starting the motor 22, the bidirectional lead screw 21 is rotated, which in turn drives the sliders 23 to move, thereby causing the two uprights 3 to move closer or further apart, which facilitates the adjustment of the clamping range according to the tire size.

[0044] The upright frame 3 has a lifting structure 4 inside, and a mounting block 5 is provided on the lifting structure 4. The lifting structure 4 includes grooves 41 at both ends of the inner wall of the rectangular through hole. A screw 42 is rotatably connected between the top and bottom of the inner wall of the groove 41 at the rear end of the upright frame 3. A second motor 43 is fixedly installed on the top of the upright frame 3. The output end of the second motor 43 is fixedly connected to the top of the screw 42. A sliding rod is fixedly connected between the top and bottom of the inner wall of the groove 41 at the front end of the upright frame 3. A connecting rod 44 is slidably connected in the groove 41. One end of the connecting rod 44 is threaded to the screw 42, and the other end of the connecting rod 44 is slidably connected to the sliding rod. The mounting block 5 is fixedly connected to the connecting rod 44. The second motor 43 drives the screw 42 to rotate. The rotation of the screw 42 drives the connecting rod 44 to move, which in turn drives the mounting block 5 to move up and down. This makes it easy to adjust the clamping and flipping height according to the tire size, which improves the range of use of the device. At the same time, when placing a tire, the clamping structure 8 can be lowered to the bottom of the upright frame 3, which is convenient for workers to place the tire, saving time and effort.

[0045] A flipping structure 6 is provided on one side opposite to the mounting block 5, and a U-shaped clamping frame 7 is provided on the opposite side of the flipping structure 6. The flipping structure 6 includes a motor 61 fixedly installed on one side of the mounting block 5. A rotating shaft 62 is rotatably connected to the mounting block 5. One end of the rotating shaft 62 is fixedly connected to the output end of the motor 6, and the other end of the rotating shaft 62 is fixedly connected to the U-shaped clamping frame 7. The mounting blocks 5 on both sides are provided with a motor 61 for flipping, which can improve the efficiency of flipping and avoid the problem that only one side of the motor drives the flipping, thus reducing the service life of the device.

[0046] The U-shaped clamping frame 7 has a clamping structure 8 inside. The clamping structure 8 includes a cylinder 81 fixedly installed at the upper end of the U-shaped clamping frame 7. A fastening plate 82 is fixedly installed at the output end of the cylinder 81. A rubber pad 83 is fixedly installed at the bottom of the fastening plate 82. A pressure sensor 84 is fixedly embedded in the middle of the lower end of the U-shaped clamping frame 7. The cylinder 81 drives the fastening plate 82 to press down, thereby fixing the tire. During the fixing process, the pressure sensor 84 inside the U-shaped clamping frame 7 detects the pressure value and transmits the pressure detection value to the control terminal. The control terminal compares the detected pressure value with the pressure value set by the operator in advance. When the detected pressure value reaches the preset pressure value, the control terminal controls the cylinder 81 to stop working, thereby avoiding damage to the tire due to excessive clamping force during the clamping process. At the same time, the rubber pad 83 at the lower end of the fastening plate 82 can protect the tire during the clamping process and prevent tire damage.

[0047] An auxiliary structure 9 is provided between the mounting block 5 and the U-shaped clamping frame 7. The auxiliary structure 9 includes an annular groove 91 on the opposite side of the mounting block 5. A plurality of support rods 92 are fixedly connected to the side of the U-shaped clamping frame 7 near the mounting block 5. The plurality of support rods 92 are evenly distributed in a circle. The ends of the support rods 92 are provided with balls 93. The support rods 92 are slidably connected to the annular groove 91 through the balls 93. In order to prevent the U-shaped clamping frame 7 from being difficult to rotate due to the excessive weight of the tire, a motor 61 for flipping is provided on both sides of the mounting block 5. At the same time, support rods 92 and balls 93 are installed on the back of the U-shaped clamping frame 7, so that the balls 93 move in the annular groove 91 on the surface of the mounting block 5. This can relieve most of the pressure on the tire and make the U-shaped clamping frame 7 easier to rotate.

[0048] In practical implementation, this invention is used by first starting motor 22 according to the tire size, driving the bidirectional lead screw 21 to rotate, which in turn moves the slider 23, causing the two uprights 3 to move closer or further apart. Then, starting motor 43 drives screw 42 to rotate, which in turn moves connecting rod 44, causing mounting block 5 to descend to the bottom of upright 3, facilitating tire placement. After the tire is placed, starting cylinder 81 drives fastening plate 82 to press down, thus fixing the tire. During the fixing process, pressure sensor 84 inside U-shaped clamping frame 7 detects the pressure value to prevent damage to the tire due to excessive clamping force. Then, starting motor 43 drives mounting block 5 to move upward to a suitable height. After that, starting motor 61 drives U-shaped clamping frame 7 to rotate. At the same time, support rod 92 moves within annular groove 91 on the surface of mounting block 5 via ball bearing 93, which relieves most of the pressure on the tire, making rotation of U-shaped clamping frame 7 easier, saving time and effort, and improving the practicality of the device.

[0049] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
