Description

Technical Field

[0001] This utility model relates to the field of aircraft tire removal technology, and in particular to a semi-automatic hydraulic tire remover. Background Technology

[0002] The wheel consists of a tire and a rim. During maintenance, the tire needs to be removed from the rim. This requires squeezing both sides of the tire to separate it from the rim, and removing the rim flange while one side of the tire is compressed. Because the tire and rim generate high temperatures during prolonged high-speed rotation and braking, the rim and tire are prone to sticking together, making tire removal very difficult. A tire removal tool is needed to separate the stuck parts before disassembly.

[0003] Most of the tire removal machines currently equipped on aircraft are horizontal tire removal machines. Since the wheels weigh between 100 and 200 kg, at least four people are needed to lift the wheels onto the working surface when removing or installing them. This consumes a lot of manpower, is inconvenient for staff to operate, and is prone to safety accidents. Utility Model Content

[0022] This utility model provides a semi-automatic hydraulic tire remover, including a frame body 1, a sloping platform 2, an operating component, a pressure plate structure 3, and an adjustment component. A wheel receiving frame 11 and an operating placement frame 12 are arranged side-by-side on the upper part of the frame body 1. The lower end of the opening of the wheel receiving frame 11 is rotatably connected to the lower end of the sloping platform 2, and the upper end of the opening of the wheel receiving frame 11 is detachably connected to the upper end of the sloping platform 2. The sloping platform 2 has a lowered state and a retracted state. When the sloping platform 2 is in the lowered state, it is tilted, and its upper end touches the ground. When the sloping platform 2 is in the retracted state, it is vertical, and its upper end connects to the upper end of the opening of the wheel receiving frame 11, thereby blocking the opening of the wheel receiving frame 11. The operating component and the adjustment component are both installed on the operating placement frame 12 and connected to each other. The adjustment component is connected to the pressure plate structure 3 and the adjustment component can push the pressure plate structure 3 to move. The pressure plate structure 3 can press the machine wheel 4 located in the machine wheel receiving frame 11. This utility model provides a semi-automatic hydraulic tire remover. During tire removal, the upper end of the inclined platform 2 is first separated from the upper end of the opening of the wheel receiving frame 11. Then, the inclined platform 2 is rotated so that its upper end contacts the ground, forming a transport channel. Only one operator is needed to roll the wheel 4 through the transport channel into the wheel receiving frame 11. The movement of the adjusting component is then controlled by the operating component, causing the pressure plate structure 3 to press against one side of the wheel 4, separating the tire from the rim. Next, the wheel 4 is removed, turned over, and placed back into the wheel receiving frame 11. The pressure plate structure 3 then presses against the other side of the wheel 4, completing the tire and rim separation. This utility model requires only one operator to complete the tire removal work, saving manpower and solving the technical problem of the high manpower required by existing horizontal tire removers.

[0023] As an optional implementation, the adjustment assembly includes a lifting adjustment assembly 5 and a horizontal adjustment assembly 6. The lifting adjustment assembly 5 is installed inside the operating placement frame 12, and the horizontal adjustment assembly 6 is located below the lifting adjustment assembly 5. The horizontal adjustment assembly 6 is slidably connected to the operating placement frame 12. The horizontal adjustment assembly 6 is connected to the lifting adjustment assembly 5, and the lifting adjustment assembly 5 can push the horizontal adjustment assembly 6 to move up and down. The operating assembly is connected to the horizontal adjustment assembly 6 through a hydraulic pipeline, and the operating assembly can drive the horizontal adjustment assembly 6 to move. The horizontal adjustment assembly 6 is connected to the pressure plate structure 3, and the horizontal adjustment assembly 6 can push the pressure plate structure 3 to move horizontally.

[0024] As an optional implementation, the horizontal adjustment assembly 6 includes a bidirectional hydraulic cylinder 61, a fixed plate 62, a movable plate 63, a guide rod 64, and a connector 65.

The connector 65 is connected to the movable plate 63 and is connected to the pressure plate structure 3 via a pin. One end of the guide rod 64 is connected to the movable plate 63, and the other end of the guide rod 64 passes through the fixed plate 62. The guide rod 64 and the fixed plate 62 are movably connected via a linear bearing 68. There are multiple guide rods 64. The guide rods 64 serve a guiding function and also a supporting function. All guide rods 64 are distributed around the bidirectional hydraulic cylinder 61. Slider 621 is provided on both ends of the fixed plate 62, and slide rails 121 are provided on both sides of the operating frame 12. The slide rails 121 are vertically arranged, and the slider 621 is slidably connected to the slide rails 121. A connecting seat 622 is provided on the fixed plate 62, and the lifting adjustment component 5 is connected to the connecting seat 622 through a rotating shaft. Under the push of the hydraulic oil of the operating component, the piston rod on the bidirectional hydraulic cylinder 61 will extend or retract, thereby driving the moving plate 63, guide rod 64 and connecting head 65 to move horizontally, thereby pushing the pressure plate structure 3 to move horizontally.

[0025] As an optional implementation, the lifting adjustment assembly 5 includes a housing body 51, a screw 52, ​​a connecting shaft 56, a handwheel 53, a drive gear, a limiting structure 54, and a fixing head 55. The housing body 51 is mounted on a seat on the operating placement frame 12. Both the connecting shaft 56 and the screw 52 pass through the housing body 51 and are arranged perpendicularly. The drive gear is located inside the housing body 51. The connecting shaft 56 is connected to the inner ring of the drive gear. The drive gear is meshed with the screw 52. One end of the connecting shaft 56 is connected to the handwheel 53, and the other end of the connecting shaft 56 is connected to the limiting structure 54. The lower end of the screw 52 is connected to the fixing head 55 through a bearing. The fixing head 55 is connected to the connecting seat 622 through a rotating shaft. By manually cranking handwheel 53, the connecting shaft 56 rotates, which in turn drives the drive gear to rotate. This causes the screw 52 to rotate downwards or upwards, which in turn causes the fixed head 55 to move up and down. Finally, this causes the leveling adjustment component 6 to move up and down, which in turn causes the pressure plate structure 3 to move up and down. The leveling adjustment component 5 is used to adjust the center position between the pressure plate structure 3 and the machine wheel 4.

[0026] As an optional implementation, the limiting structure 54 includes a limiting gear 541, a limiting rod 542, a limiting bracket 543, a sleeve 544, and a pull ring 545.

The lower end of the limiting rod 542 is provided with teeth 5421, which can extend into the tooth grooves of the limiting gear 541. The sleeve 544 is provided with two sets of limiting grooves 5441 of different depths, and the side wall of the limiting rod 542 is provided with two positioning heads 5422, which can cooperate with the limiting grooves 5441. Before cranking the handwheel 53, the pull ring 545 needs to be pulled up to pull the positioning head 5422 into the shallower limiting groove 5441. At this time, the teeth 5421 are separated from the limiting gear 541 and will not restrict the rotation of the connecting shaft 56. If the height of the pressure plate structure 3 is adjusted, the pull ring 545 is pulled up again to pull the positioning head 5422 into the deeper limiting groove 5441. At this time, the teeth 5421 extend into the tooth grooves of the limiting gear 541, thereby restricting the limiting gear 541 and preventing the connecting shaft 56 from rotating.

[0027] As an optional implementation, the operating components include an electro-hydraulic drive structure 7, a manual hydraulic drive structure 8, a first handle valve 9, a second handle valve 10, and an oil tank 20.

The connecting tube 36 has a bent structure, and the connector 65 is inserted into the connecting sleeve 31 and connected to the connecting sleeve 31 by a pin. The diameter of the first annular tube 33 is smaller than the diameter of the second annular tube 34. The second annular tube 34 directly contacts the wheel 4, thereby applying pressure to the wheel 4. The pressure plate structure 3 can be replaced to accommodate wheel 4s of different sizes.

[0031] As an optional implementation, the front end of the frame body 1 is provided with a rotatable traction component 13 and a limiting member 14 that restricts the rotation of the traction component 13. A caster assembly 15 is provided below the frame body 1. The operator pulls the traction component 13, thereby causing the frame body 1 to move under the rolling of the caster assembly 15. When it is not necessary to move the frame body 1, the traction component 13 is placed vertically and restricted by the limiting member 14.

[0032] The inner wall of the wheel housing 11 is covered with a soft elastic pad. When the pressure plate structure 3 presses one side of the wheel 4, the other side of the wheel 4 will come into contact with the soft elastic pad, thereby protecting the wheel 4.

When the wheel 4 enters the wheel receiving frame 11, a part of the wheel 4 will be located in the limiting opening 111, thereby limiting the wheel 4. At the same time, it is to ensure that the wheel 4 is in the same position every time it enters the wheel receiving frame 11.

[0033] When operating electrically: First, rotate the handles on the first handle valve 9 and the second handle valve 10 to the vertical downward position, so that both the first handle valve 9 and the second handle valve 10 are connected to the electro-hydraulic drive structure 7, but not to the manual hydraulic drive structure 8. Then, the switching power supply is powered on, the hydraulic control structure 30 is started, and the inclined platform 2 is lowered at the same time. Next, the wheel 4 is rolled into the wheel housing 11 and limited by the limiting port 111; Next, manually adjust the lifting adjustment component 5 to align the center positions of the pressure plate structure 3 and the machine wheel 4. Next, the hydraulic control structure 30 controls the electric pump 71, so that the hydraulic oil in the oil tank 20 enters the first cavity of the double-acting hydraulic cylinder 61 through the first handle valve 9, thereby pushing the piston rod to extend, so that the pressure plate structure 3 moves towards the wheel 4 and presses it, so that the tire separates from the wheel hub and the half ring is removed. At the same time, the hydraulic oil in the second cavity of the double-acting hydraulic cylinder 61 flows back to the oil tank 20 through the second handle valve 10 under the push of the piston rod. Then, the electric pump 71 is controlled by the hydraulic control structure 30, so that the hydraulic oil in the oil tank 20 enters the second cavity on the bidirectional hydraulic cylinder 61 through the second handle valve 10, thereby pushing the piston rod to retract, so that the pressure plate structure 3 moves away from the wheel 4. At the same time, the hydraulic oil in the first cavity on the bidirectional hydraulic cylinder 61 flows back to the oil tank 20 through the first handle valve 9 under the push of the piston rod. Finally, turn wheel 4 over, then control the bidirectional hydraulic cylinder 61 to extend and retract, thereby separating the tire from the other side of the hub. Close the hydraulic control structure 30, remove wheel 4, and retract the inclined platform 2.

[0034] When performing manual operation: First, rotate the handles on the first handle valve 9 and the second handle valve 10 to a horizontal position, so that both the first handle valve 9 and the second handle valve 10 are connected to the manual hydraulic drive structure 8, but not to the electric hydraulic drive structure 7. Next, turn the handle on the channel switching valve 82 to one side, while the inclined platform 2 is in the lowered state; Next, the wheel 4 is rolled into the wheel housing 11 and limited by the limiting port 111; Next, manually adjust the lifting adjustment component 5 to align the center positions of the pressure plate structure 3 and the machine wheel 4. Next, by inserting the pressing rod into the manual pump 81 and manually pressing the pressing rod back and forth, the hydraulic oil in the oil tank 20 enters the first cavity of the double-acting hydraulic cylinder 61 through the first handle valve 9, thereby pushing the piston rod to extend, so that the pressure plate structure 3 moves towards the wheel 4 and presses it, so that the tire separates from the hub and the half ring is removed. At the same time, the hydraulic oil in the second cavity of the double-acting hydraulic cylinder 61 flows back into the oil tank 20 through the second handle valve 10 under the push of the piston rod. Then, turn the handle on the channel switching valve 82 to the other side, so that the hydraulic oil in the oil tank 20 enters the second cavity on the bidirectional hydraulic cylinder 61 through the second handle valve 10, thereby pushing the piston rod to retract, so that the pressure plate structure 3 moves away from and closer to the wheel 4. At the same time, the hydraulic oil in the first cavity on the bidirectional hydraulic cylinder 61 flows back to the oil tank 20 through the first handle valve 9 under the push of the piston rod. Finally, turn wheel 4 over, and then control the bidirectional hydraulic cylinder 61 to extend and retract, so that the tire is separated from the other side of the hub, wheel 4 is removed, and the inclined platform 2 is retracted.

[0035] The electro-hydraulic drive structure 7 and the manual hydraulic drive structure 8 can be used in combination.
