[0014] Compared with the prior art, the present invention provides a tire hoisting device and a hoisting method for solid rubber tires, and has the following beneficial effects: 1. For the tire hoisting device and the hoisting method for solid rubber tires, through the setting of the driving component and the hoisting mechanism, when hoisting the tire, after the crane main body lowers the fixed arm to an appropriate height through the hoisting rope, the staff turns the fixed arm towards the tire to be hoisted.

[0015] 2. For the tire hoisting device and the hoisting method for solid rubber tires, through the cooperation of the adjusting component and the clamping component, when the driving rod drives the clamping disks to close and clamp the tire, the transmission rod installed in the driving rod drives the spur gear on the rotating shaft to rotate under the drive of the driving rack, so that the spur gear drives the connecting rod to contract into the receiving groove, thereby reducing the distance between the clamping disks and the fixed arm. When the clamping disks clamp both sides of the tire, the contact area between the clamping disks and the tire is the maximum contact area, so that the clamping effect of the clamping component is better, and the tire can be firmly grasped and not easily fall off. Moreover, through the cooperation of the driving rod and the connecting rod, it can be applicable to tires of various models, thereby increasing the applicability of the device.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figures 1-8 , a tire hoisting device, including a crane main body 1 and a hoisting rope 11 connected to the crane main body 1. A driving assembly 2 and a hoisting mechanism 3 are arranged on the crane main body 1. The hoisting mechanism 3 includes a connecting piece 31, a fixed arm 32, an adjusting assembly 4 and a clamping assembly 5. The upper end of the connecting piece 31 is connected to the hoisting rope 11. The fixed arm 32 is installed on the connecting piece 31. The driving assembly 2 is installed at the end of the fixed arm 32. The adjusting assembly 4 includes a driving rod 41, a transmission rod 43 and a rotating shaft 44. The two driving rods 41 are respectively installed at both ends of the fixed arm 32. The driving rod 41 cooperates with the driving assembly 2. The driving assembly 2 is used to drive the driving rod 41 to move linearly on the fixed arm 32. A storage groove 411 is opened on the driving rod 41. The transmission rod 43 and the rotating shaft 44 are sequentially installed in the driving rod 41. When the driving rod 41 moves, it can drive the rotating shaft 44 to rotate through the transmission rod 43. The clamping assembly 5 includes a clamping disc 51 and a connecting rod 52. The clamping disc 51 is connected to one end of the connecting rod 52. The other end of the connecting rod 52 is installed in the storage groove 411 and cooperates with the rotating shaft 44. When the driving rod 41 drives the connecting rod 52 to move, the rotating rotating shaft 44 drives the connecting rod 52 to move in the storage groove 411, adjusts the clamping disc 51 to the corresponding position, and clamps the tire.

[0020] Among them, when in use, first move the device next to the maintenance vehicle. The crane main body 1 lowers the hoisting mechanism 3 to the side of the old tire to be replaced through the hoisting rope 11. After the old tire is disassembled by the staff, manually turn the fixed arm 32 towards the old tire to align the opened clamping assembly 5 with the old tire vertically installed on the vehicle. Then start the driving assembly 2, and the adjusting assembly 4 controls the clamping disc 51 to clamp the tire. Among them, initially, the two driving rods 41 are respectively located at both ends of the fixed arm 32, the clamping disc 51 is opened to the maximum extent, and the connecting rod 52 extends from the storage groove 411 to the maximum length, and the clamping disc 51 hangs down naturally. When the driving assembly 2 is started, the two driving rods 41 at both ends of the fixed arm 32 move towards the connecting piece 31 at the same time, causing the opened clamping disc 51 to start closing. At the same time, the moving driving rod 41 will drive the transmission rod 43 to drive the rotating shaft 44 to rotate in the reverse direction, and the rotating shaft 44 thus drives the connecting rod 52 to move into the storage groove 411, so that when the clamping disc 51 clamps both sides of the old tire, the contact area between the side of the old tire and the clamping disc 51 is the largest, so that the clamping disc 51 can firmly grasp the old tire. After the clamping disc 51 firmly grasps the old tire, the driving assembly 2 pauses. Subsequently, the staff pushes the old tire away from the maintenance vehicle, and the crane main body 1 then hoists the old tire through the hoisting rope 11. At the same time, the staff stops rotating the fixed arm 32, and the originally vertical old tire drives the fixed arm 32 to rotate downward into a lying state under the action of gravity. After hoisting the old tire, the staff controls the crane main body 1 to move to the stacking place of the old tire and stack the old tire on the stacked tires. During this process, the staff first moves the crane main body 1 to align the hoisted old tire with the stacked tires below, and then lowers the hoisting rope 11 to stack the old tire on the clamping disc 51 on the lower tire. Then start the driving assembly 2 to make the two driving rods 41 move in the reverse direction and move back to both ends of the fixed arm 32 respectively, so as to open the closed clamping disc 51 and end the clamping of the old tire by the clamping disc 51. At the same time, the driving rod 41 drives the rotating shaft 44 to rotate forward through the transmission rod 43, and pushes the connecting rod 52 retracted in the storage groove 411 out of the storage groove 411, so that the clamping disc 51 returns to the initial position. After completing the storage of the old tire, the staff moves the crane main body 1 to the side of the new tire to be installed on the vehicle and repeats the above steps. The new tire is clamped and hoisted through the hoisting mechanism 3 by the clamping disc 51. Then move the crane main body 1 back to the side of the maintenance vehicle, and lower the new tire to a suitable installation height through the hoisting rope 11, and manually rotate the fixed arm 32 to make the new tire stand upright and align with the axle. After the new tire is accurately installed on the maintenance vehicle, the driving assembly 2 drives the clamping disc 51 to open, ending the clamping of the new tire, so as to assist the staff in completing the repair of the vehicle.

[0021] The difference from the above embodiment is that a reversing groove 321 is provided in the middle of the fixed arm 32, and the upward side and the side away from the crane body 1 are open, and displacement grooves 322 are provided at both ends of the fixed arm 32, and the downward side of the displacement groove 322 is open, and a driving rack 323 is fixedly installed on the side of the displacement groove 322 close to the crane body 1, and a wrench 33 is fixedly connected to the fixed arm 32, and the wrench 33 is located on the side of the reversing groove 321.

[0022] Among them, during the process of lifting the tire, when the clamping plate 51 needs to be aligned with the tire, the staff uses the wrench 33 to push the fixed arm 32 upward on the connecting piece 31, so that the side of the reversing groove 321 away from the crane body 1 faces upward, and the side of the reversing groove 321 originally facing upward turns to face the crane body 1, thereby aligning the clamping plate 51 of the clamping assembly 5 toward the tire to be lifted. When lifting the tire, the staff releases the wrench 33, and the fixed arm 32 turns back to its original state under the action of gravity, thereby laying the tire flat.

[0023] The difference from the above embodiment is that the driving assembly 2 includes a driving motor 21, and the two driving motors 21 are respectively fixedly installed at the two ends of the fixed arm 32, and the output shaft of the driving motor 21 passes through the side wall of the displacement groove 322 and extends into the displacement groove 322. The output shaft of the driving motor 21 is coaxially fixedly connected with one end of the threaded rod 22, and the other end of the threaded rod 22 is rotatably installed in the displacement groove 322.

[0024] After the driving assembly 2 is started, when the clamping assembly 5 is required to clamp the tire, the driving motor 21 drives the threaded rod 22 to rotate in the reverse direction, and when the clamping assembly 5 is required to release the tire, the driving motor 21 drives the threaded rod 22 to rotate in the forward direction.

[0025] The difference from the above embodiment is that the driving rod 41 is slidably installed in the displacement groove 322, and one end of the driving rod 41 located in the displacement groove 322 is assembled on the threaded rod 22 through a thread, and the threaded rod 22 can drive the driving rod 41 to move in the displacement groove 322 when it rotates, and the other end of the driving rod 41 is provided with a transmission groove 414, and the transmission groove 414 is located on the side of the receiving groove 411, and a mounting seat 42 is fixedly connected in the transmission groove 414, and a notch is provided on one side of the transmission groove 414 located above the driving rack 323, so that the tooth surface of the driving rack 323 is located in the transmission groove 414, and the other side of the transmission groove 414 is connected to the receiving groove 411, and a limiting groove 412 is provided on the side wall of the receiving groove 411 close to the transmission groove 414, and a stopper 413 is fixedly installed on the side wall of the receiving groove 411, and the stopper 413 is close to the opening end of the receiving groove 411.

[0026] Wherein, when the threaded rod 22 rotates reversely, the driving rod 41 moves towards the connecting member 31 in the displacement groove 322. When the threaded rod 22 rotates forward, the driving rod 41 moves towards the end of the fixed arm 32 in the displacement groove 322. Meanwhile, during the movement of the driving rod 41, the notch of the transmission groove 414 slides along the driving rack 323.

[0027] The difference from the above embodiment is that the transmission rod 43 is rotatably installed on the mounting seat 42. A transmission gear 431 is coaxially and fixedly connected to one end of the transmission rod 43 close to the displacement groove 322. The transmission gear 431 meshes with the driving rack 323. A transmission bevel gear 432 is coaxially and fixedly connected to the other end of the transmission rod 43.

[0028] Wherein, when the driving rod 41 moves towards the connecting member 31, the transmission gear 431 drives the transmission rod 43 to drive the transmission bevel gear 432 to rotate forward under the cooperation of the driving rack 323. When the driving rod 41 moves towards the end of the fixed arm 32, the transmission gear 431 drives the transmission rod 43 to drive the transmission bevel gear 432 to rotate reversely under the cooperation of the driving rack 323.

[0029] The difference from the above embodiment is that both ends of the rotating shaft 44 are respectively rotatably installed on the side wall of the transmission groove 414 and the side wall of the receiving groove 411. A driven bevel gear 441 is coaxially and fixedly connected to one end of the rotating shaft 44 located in the transmission groove 414. The driven bevel gear 441 meshes with the transmission bevel gear 432. A spur gear 442 is coaxially and fixedly connected to one end of the rotating shaft located in the receiving groove 411. The spur gear 442 is located between the stop block 413 and the open end of the receiving groove 411.

[0030] Wherein, when the transmission bevel gear 432 rotates forward, it drives the driven bevel gear 441 to drive the spur gear 442 on the rotating shaft to rotate reversely. When the transmission bevel gear 432 rotates reversely, it drives the driven bevel gear 441 to drive the spur gear 442 on the rotating shaft to rotate forward.

[0031] The difference from the above embodiment is that the clamping disc 51 is fixedly connected to the connecting rod 52, and one side of the clamping disc 51 for clamping the tire protrudes from the side of the driving rod 41. A friction pad 511 is fixedly installed on the side of the clamping disc 51 facing the tire. A limiting strip 521 is fixedly connected to the side of the connecting rod 52. The limiting strip 521 is slidably installed in the limiting groove 412. An installation groove 522 is formed on the side of the connecting rod 52 facing the spur gear 442. One end of the installation groove 522 close to the driving assembly 2 corresponds to the stop block 413. An adjusting rack 53 is fixedly installed in the installation groove 522. The adjusting rack 53 meshes with the spur gear 442.

[0032] Among them, after the connecting rod 52 extends out of the receiving groove 411 to the maximum length, the inner side of the end of the installation groove 522 close to the driving assembly 2 abuts against the stop block 413, preventing the connecting rod 52 from moving excessively in the receiving groove 411 and continuing to extend outwards, ensuring the normal operation of the device. When it is necessary to clamp the tire, as the driving rod 41 drives the clamping disc 51 to close, the spur gear 442 rotates in the reverse direction, and through the cooperation with the adjusting rack 53, the connecting rod 52 extending out of the receiving groove 411 is driven to move into the receiving groove 411, so that the connecting rod 52 can change the position of the clamping disc 51 corresponding to the side of the tire according to the diameter of the tire, firmly grasping the tire, making the hoisting mechanism 3 applicable to tires of different models, thereby improving the applicability of the device. When it is necessary to end the clamping of the tire, as the driving rod 41 drives the clamping disc 51 to open, the spur gear 442 rotates in the forward direction, and through the cooperation with the adjusting rack 53, the connecting rod 52 retracted in the receiving groove 411 is driven to extend out of the receiving groove 411, restoring the clamping disc 51 to its original position and waiting for the next operation. Through the cooperation of the limiting strip 521 and the limiting groove 412, when the connecting rod 52 moves in the receiving groove 411, it can move in a straight line, ensuring that the clamping disc 51 will not shift and can effectively clamp the tire. At the same time, the friction pad 511 can provide friction when the clamping disc 51 clamps the tire, making the clamping effect of the clamping disc 51 better.

[0033] The difference from the above embodiment is that the connecting member 31 is rotatably installed in the reversing groove 321 through a rotating shaft, and a handle 311 is fixedly installed on the upper side of the connecting member 31.

[0034] Among them, when rotating the fixed arm 32, the staff needs to hold the handle 311 to facilitate pulling the wrench 33 to turn the fixed arm 32.

[0035] Embodiment 2: The difference from the above embodiment is that a plurality of universal wheels 6 are installed at the bottom of the crane main body 1, and the universal wheels 6 enable the crane main body 1 to move on the ground.

[0036] Among them, the universal wheel 6 is equipped with a brake. The crane main body 1 moves through the universal wheel 6. When the crane main body 1 stops moving, the staff can brake the universal wheel 6 to make the crane main body 1 stop moving, thereby providing a good working environment for the hoisting of the tire. When it is necessary to move the crane main body 1, the brake of the universal wheel 6 is released, enabling the staff to move the crane main body 1.

[0037] The present invention also provides a hoisting method for solid rubber tires, using a tire hoisting device.

[0038] Working principle: When in use, first move the device next to the maintenance vehicle. The crane main body 1 lowers the hoisting mechanism 3 to the side of the old tire to be replaced through the hoisting rope 11. After the old tire is removed by the staff, the staff holds the handle 311 and at the same time uses a wrench 33 to upwardly pull the fixed arm 32 on the connecting member 31, so that the side of the reversing groove 321 away from the crane main body 1 faces upward, while the side of the reversing groove 321 that originally faced upward turns towards the direction of the crane main body 1, thereby aligning the clamping disc 51 of the clamping assembly 5 with the old tire vertically installed on the vehicle. Then, start the driving assembly 2, and the adjusting assembly 4 controls the clamping disc 51 to clamp the tire. Among them, initially, the two driving rods 41 are respectively located at both ends of the fixed arm 32, the clamping disc 51 is opened to the maximum extent, and the connecting rod 52 extends from the receiving groove 411 to the maximum length, and the clamping disc 51 hangs naturally. When the driving assembly 2 is started, the driving motor 21 drives the threaded rod 22 to rotate in the reverse direction, and the two driving rods 41 at both ends of the fixed arm 32 move towards the connecting member 31 at the same time, causing the opened clamping disc 51 to start closing; At the same time, the moving driving rod 41 slides along the driving rack 323, and the transmission gear 431 drives the transmission rod 43 to drive the transmission bevel gear 432 to rotate forward through the cooperation with the driving rack 323, so that the driven bevel gear 441 cooperating with the transmission bevel gear 432 drives the spur gear 442 on the rotating shaft 44 to rotate in the reverse direction, thereby driving the connecting rod 52 to move into the receiving groove 411, enabling the connecting rod 52 to change the position of the clamping disc 51 corresponding to the side of the old tire according to the diameter of the old tire, so that the contact area between the side of the old tire and the clamping disc 51 is the largest, so that the clamping disc 51 can firmly grasp the old tire. After the clamping disc 51 firmly grasps the old tire, the driving assembly 2 pauses working. Subsequently, the staff pushes the old tire away from the maintenance vehicle, and the crane main body 1 then hoists the old tire through the hoisting rope 11. At the same time, the staff stops rotating the fixed arm 32, and the originally vertical old tire drives the fixed arm 32 to rotate downward into a lying state under the action of gravity. After hoisting the old tire, the staff controls the crane main body 1 to move to the stacking place of the old tires and stack the old tires on the stacked tires. During this process, the staff first moves the crane main body 1 to align the hoisted old tire with the stacked tires below, and then lowers the hoisting rope 11 to stack the old tire on the clamping disc 51 on the lower tire. Then, start the driving assembly 2; The driving motor 21 is driven to rotate the threaded rod 22 in the forward direction. The rotating threaded rod 22 drives the two driving rods 41 to move in the reverse direction and move back to both ends of the fixed arm 32 respectively, thereby opening the closed clamping disc 51 and ending the clamping of the old tire by the clamping disc 51. At the same time, the transmission gear 431 drives the transmission rod 43 to drive the transmission bevel gear 432 to rotate in the reverse direction through the cooperation with the driving rack 323, so that the driven bevel gear 441 engaged with the transmission bevel gear 432 drives the spur gear 442 on the rotating shaft 44 to rotate in the forward direction, pushing the connecting rod 52 retracted in the receiving groove 411 out of the receiving groove 411 and making the clamping disc 51 return to the initial position. Among them, after the connecting rod 52 extends out of the receiving groove 411 to the maximum length, the inner side of the end of the mounting groove 522 close to the driving assembly 2 abuts against the stopper 413, preventing the connecting rod 52 from moving excessively in the receiving groove 411 and continuing to extend outwards, ensuring the normal operation of the device. After the old tire is stored, the staff moves the crane main body 1 to the new tire to be installed on the vehicle and repeats the above steps. The new tire is clamped and lifted by the clamping disc 51 through the hoisting mechanism 3. Then, the crane main body 1 is moved back to the maintenance vehicle, and the new tire is lowered to a suitable installation height through the lifting rope 11. The fixed arm 32 is manually rotated to make the new tire stand upright and align with the axle. After the new tire is accurately installed on the maintenance vehicle, the driving assembly 2 drives the clamping disc 51 to open, ending the clamping of the new tire, thereby assisting the staff to complete the repair of the vehicle.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
