The tires of large-horsepower tractors are relatively large, and it is extremely difficult and dangerous for ordinary farmers to replace the tires alone. The replacement of tires for other large vehicles also has the problem of great difficulty. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is how to facilitate the replacement of large tires.

[0004] The technical solution for the utility model to solve the above technical problem is as follows: A tire disassembly and assembly auxiliary device, including a telescopic driving mechanism, a first bracket, a second bracket, and a tire guiding and supporting platform. One end of the first bracket and one end of the second bracket are in transverse sliding fit. There are two tire guiding and supporting platforms, and the two tire guiding and supporting platforms are respectively fixedly connected to the other end of the first bracket and the other end of the second bracket. The two tire guiding and supporting platforms are arranged facing each other and inclined in the direction away from each other. The telescopic driving mechanism includes a driving main body and a driving piston rod in sliding fit. The driving main body is fixedly connected to the first bracket, and the driving piston rod is fixedly connected to the second bracket.

[0005] The beneficial effect of the utility model is that the telescopic driving mechanism expands and contracts, thereby driving the first bracket and the second bracket to approach or move away from each other. The two tire guiding and supporting platforms are located on both sides of the lower part of the tire to be disassembled and assembled and are in contact with the arc-shaped outer wall of the tire. The two tire guiding and supporting platforms approach or move away from each other as the first bracket and the second bracket move, thereby lifting or lowering the tire, facilitating the tightening or loosening of the nuts on the tire, and facilitating the movement of the tire. Using the tire disassembly and assembly auxiliary device can achieve the disassembly and assembly of large tires by a single person easily.

[0006] On the basis of the above technical solution, the utility model can also be improved as follows.

[0007] Further, the telescopic driving mechanism is a servo electric cylinder.

[0008] The beneficial effect of adopting the above further solution is that the selection of a servo electric cylinder for the auxiliary device can achieve electric telescoping, stepless speed change, precise control, realize tire clamping and precise positioning, and can realize the light installation of large tires.

[0009] Moreover, compared with manual or hydraulic auxiliary equipment, the outstanding advantage of choosing a servo electric cylinder is stepless speed regulation, which realizes the advantages of adjustable speed and precise positioning, enabling an operator to easily and accurately disassemble and assemble tires alone, and greatly improving the efficiency of tire replacement. The selected servo electric cylinder has a large torque and strong load-bearing capacity, with a maximum load of 1200 kg, capable of performing the disassembly and assembly work of heavy-duty tires. The used servo electric cylinder has a braking function and realizes self-locking after power-off, ensuring that the equipment can still maintain its original state after abnormal power-off, without the need for parts such as pins to lock it, making it safer to use.

[0010] Furthermore, it further includes a power distribution cabinet and a storage battery. Both the power distribution cabinet and the storage battery are fixed on the first bracket.

[0012] Furthermore, it further includes universal wheels. A plurality of the universal wheels are installed at the bottoms of both the first bracket and the second bracket.

[0013] The beneficial effect of adopting the above further solution is that universal wheels are installed at the bottoms of the first bracket and the second bracket, enabling the equipment to move freely and quickly after clamping the tire, and easily separating from and combining with the vehicle when disassembling and installing the tire.

[0014] Furthermore, it further includes a longitudinal telescopic rod and a transverse limiting rod. The lower end of the longitudinal telescopic rod is fixedly connected to the outer wall of one end of the first bracket. One end of the transverse limiting rod is horizontally slidably connected to the upper end of the longitudinal telescopic rod, and the other end of the transverse limiting rod has a limiting section extending downward.

[0015] The beneficial effect of adopting the above further solution is that the longitudinal telescopic rod can be telescoped up and down to enable the transverse limiting rod to clamp the tire in the up and down directions, adapting to tires of different specifications. The transverse limiting rod can move horizontally under the guidance of the upper end of the longitudinal telescopic rod, playing a role in axial support and anti-tipping of the tire.

[0016] Furthermore, the transverse limiting rod is a round rod, and the upper end of the longitudinal telescopic rod has a circular fitting hole. The transverse limiting rod is slidably connected to the circular fitting hole.

[0017] The beneficial effects of adopting the above further scheme are as follows: The lateral limiting rod is in sliding fit with the circular mating hole to achieve lateral telescoping. At the same time, the lateral limiting rod can also rotate around the axis, so that when the limiting section of the lateral limiting rod approaches the tire from one side of the tire, it can be manually rotated to the horizontal or other angles to avoid the tire. After the limiting section moves to the other side of the tire, the limiting section can rotate downward under its own weight to prevent the tire from tipping over.

[0018] Further, one end of the lateral limiting rod has a limiting portion.

[0019] The beneficial effects of adopting the above further scheme are as follows: A limiting portion is provided at one end of the lateral limiting rod to prevent the lateral limiting rod from disengaging from the circular mating hole.

[0032] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0033] As Figures 1-4 shown, this embodiment provides an auxiliary equipment for tire disassembly and assembly, including a telescopic driving mechanism 3, a first bracket 7, a second bracket 8, and a tire guiding and supporting platform 1. One end of the first bracket 7 and one end of the second bracket 8 are in transverse sliding fit. There are two tire guiding and supporting platforms 1, and the two tire guiding and supporting platforms 1 are respectively fixedly connected to the other end of the first bracket 7 and the other end of the second bracket 8. The two tire guiding and supporting platforms 1 are arranged facing each other and inclined in the direction away from each other. The telescopic driving mechanism 3 includes a driving body and a driving piston rod in sliding fit. The driving body is fixedly connected to the first bracket 7, and the driving piston rod is fixedly connected to the second bracket 8.

[0034] The telescopic driving mechanism 3 expands and contracts, thereby driving the first bracket 7 and the second bracket 8 to approach or move away from each other. The two tire guiding and supporting platforms 1 are located on both sides of the lower part of the tire to be disassembled and assembled and are in contact with the arc-shaped outer wall of the tire. The two tire guiding and supporting platforms 1 approach or move away from each other as the first bracket 7 and the second bracket 8 move, so as to lift or lower the tire, facilitating the tightening or loosening of the nuts on the tire and facilitating the movement of the tire. Using the auxiliary equipment for tire disassembly and assembly can enable a single person to easily carry out the disassembly and assembly work of large tires.

[0035] Optionally, the telescopic driving mechanism 3 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0036] In one relatively preferred example, the telescopic driving mechanism 3 is a servo electric cylinder.

[0037] The selected servo electric cylinder for this auxiliary device can achieve electric telescoping, stepless speed change, and precise control, enabling tire clamping and precise positioning, and making the installation of large tires more convenient.

[0038] Moreover, compared with manual or hydraulic auxiliary devices, the outstanding advantage of selecting a servo electric cylinder is stepless speed change adjustment, achieving the advantages of adjustable speed and precise position, enabling an operator to easily and accurately disassemble and assemble tires alone, and greatly improving the tire replacement efficiency at the same time. The selected servo electric cylinder has a large torque and strong bearing capacity, with a maximum load capacity of 1200 kg, and can realize the disassembly and assembly of heavy-duty tires. The used servo electric cylinder has a braking function and realizes self-locking after power-off, ensuring that the equipment can still maintain its original state after abnormal power-off, without using components such as pins for locking, and is safer to use.

[0039] Among them, a servo electric cylinder with a large stroke can be selected, with a stroke of 1000 mm, which can realize the disassembly and assembly of tires with a diameter ranging from 1000 mm to 2000 mm. Of course, servo electric cylinders with other strokes can also be selected according to the size of the tires.

[0040] Specifically, the selected servo electric cylinder is a servo electric cylinder of the Leadshine Intelligence brand, with fast response and large torque. The power of this electric cylinder is 0.75 Kw, the torque is 2.39 N·m, and the lifting force can reach 1200 kg, meeting the lifting requirements of large tires with a large weight. The rotation speed is 3000 r / min, with a fast rotation speed, and can realize fast stepless adjustment to ensure precise positioning and precise control during the disassembly and assembly of tires.

[0041] Specifically, for the disassembly and assembly of large-horsepower tractor tires, the most commonly used auxiliary equipment in the industry at present is hydraulic disassembly and assembly equipment. If a hydraulic type is selected, physical strength is required to operate the hydraulic oil pump, it is difficult to maintain body balance, and there are potential safety hazards. At the same time, the speed and accuracy of the hydraulic oil pump type are poor, and it is difficult to accurately position the rim mounting holes and hub bolts. Using the servo electric cylinder of this embodiment can achieve stepless speed adjustment and stepless position adjustment. The tire disassembly and assembly auxiliary equipment has safety, accuracy, and high efficiency.

[0042] On the basis of the above technical solution, it further includes a power distribution cabinet 5 and a storage battery 6. The power distribution cabinet 5 and the storage battery 6 are both fixed on the first bracket 7. A controller is provided in the power distribution cabinet 5, and the controller is communicatively connected with the servo electric cylinder. The storage battery 6 is electrically connected to the controller and the servo electric cylinder respectively.

[0043] The storage battery 6 supplies power to the power distribution cabinet 5 and the servo electric cylinder. Compared with plug-in equipment, the power supply of the rechargeable storage battery 6 enables the equipment to be used without being restricted by the working site, improving its practicality.

[0044] Specifically, the power distribution cabinet 5 is provided with a cooling fan, an emergency stop button, a jogging extension button, a jogging retraction button, a speed regulation knob, a power switch, a power indicator, etc. that are connected to the controller. The jogging extension button, the jogging retraction button, and the speed regulation knob are used to control the extension, retraction, and speed of the telescopic drive mechanism 3. The emergency stop button is used to urgently stop the telescopic drive mechanism 3. The power switch controls the connection or disconnection of the circuit between the storage battery 6 and the controller or the servo electric cylinder. The power indicator indicates whether the circuit of the storage battery 6 is connected. The control circuit of the power distribution cabinet 5 can be implemented by existing technologies and will not be elaborated here.

[0045] Specifically, the storage battery 6 is a 24V storage battery, which can supply power to the power distribution cabinet 5 and the telescopic drive mechanism 3. Selecting a storage battery instead of AC power supply can enable the work of tire replacement when there is no AC power outdoors.

[0046] On the basis of the above technical solution, it further includes universal wheels 4, and a plurality of the universal wheels 4 are installed at the bottoms of the first bracket 7 and the second bracket 8.

[0047] The universal wheels 4 are installed at the bottoms of the first bracket 7 and the second bracket 8, enabling the equipment to move freely and quickly after clamping the tire, and facilitating the easy separation from and combination with the vehicle during tire disassembly and installation.

[0048] On the basis of the above technical solution, it further includes a longitudinal telescopic rod 2 and a transverse limiting rod 9. The lower end of the longitudinal telescopic rod 2 is fixedly connected to the outer wall of one end of the first bracket 7, one end of the transverse limiting rod 9 is horizontally slidably connected to the upper end of the longitudinal telescopic rod 2, and the other end of the transverse limiting rod 9 has a limiting section extending downward.

[0049] The longitudinal telescopic rod 2 can be telescoped up and down to enable the transverse limiting rod 9 to clamp the tire in the up and down directions, adapting to tires of different specifications. The transverse limiting rod 9 can move horizontally under the guidance of the upper end of the longitudinal telescopic rod 2, playing a role in axially supporting the tire and preventing it from tipping over.

[0050] Specifically, the relative sliding direction of the first bracket 7 and the second bracket 8 is perpendicular to the transverse limiting rod 9. After two tire guiding and supporting platforms 1 clamp a tire, the transverse limiting rod 9 is parallel to the tire axis.

[0051] Optionally, the longitudinal telescopic rod 2 can be selected from an electric telescopic rod, a pneumatic telescopic rod, a hydraulic telescopic rod, or a sleeve formed by multiple sections slidingly cooperating in sequence. In one specific example, the longitudinal telescopic rod 2 includes two sleeves slidingly cooperating, which can be manually elongated. After releasing the hand, the longitudinal telescopic rod 2 shortens under its own weight and presses the transverse limiting rod 9 onto the top of the tire to limit the tire in the up and down directions.

[0052] On the basis of the above technical solution, the transverse limiting rod 9 is a round rod, the upper end of the longitudinal telescopic rod 2 has a circular fitting hole, and the transverse limiting rod 9 is slidably connected to the circular fitting hole.

[0053] The transverse limiting rod 9 is slidably fitted with the circular fitting hole to achieve transverse expansion and contraction. At the same time, the transverse limiting rod 9 can also rotate around the axis, so that when the limiting section of the transverse limiting rod 9 approaches the tire from one side of the tire, it can be manually rotated to the horizontal or other angles to avoid the tire. After the limiting section moves to the other side of the tire, the limiting section can rotate downward under its own weight to prevent the tire from tipping over.

[0054] On the basis of the above technical solution, one end of the transverse limiting rod 9 has a limiting portion.

[0055] A limiting portion is provided at one end of the transverse limiting rod 9 to prevent the transverse limiting rod 9 from disengaging from the circular fitting hole.

[0056] Optionally, the limiting portion is a protrusion at one end of the transverse limiting rod 9, or the limiting portion is a limiting pin. A plurality of limiting through holes are spaced along the length direction of the side wall of the transverse limiting rod 9, and the limiting pin can be inserted into one of the limiting through holes.

[0057] On the basis of the above technical solution, each tire guiding and supporting platform 1 is rotatably connected with a plurality of rollers from top to bottom in sequence, and the axis of each roller is horizontally arranged.

[0058] Rollers are arranged on the tire guiding and supporting platform 1 to reduce the resistance when two tire guiding and supporting platforms 1 clamp and lift the tire.

[0059] On the basis of the above technical solution, the first bracket 7 includes a first rod member 71 and a second rod member 72. One end of the first rod member 71 is fixedly connected to one end of the second rod member 72. The first rod member 71 and the second rod member 72 are perpendicular. The tire guiding and supporting platform 1 is fixedly connected to the first rod member 71, and the second rod member 72 has a sliding hole; the second bracket 8 includes a third rod member 81 and a fourth rod member 82. One end of the third rod member 81 is fixedly connected to one end of the fourth rod member 82. The third rod member 81 and the fourth rod member 82 are perpendicular. The tire guiding and supporting platform 1 is fixedly connected to the third rod member 81, and the other end of the fourth rod member 82 is slidably fitted with the sliding hole.

[0060] Both the first bracket 7 and the second bracket 8 are L-shaped, with simple structure, compact layout and low manufacturing cost.

[0061] Specifically, the driving body of the telescopic driving mechanism 3 is fixedly connected to the second rod member 72, and the driving piston rod is fixedly connected to the fourth rod member 82.

[0062] On the basis of the above technical solution, it further includes two columns 10. The two columns 10 are both vertically arranged and are respectively fixedly connected to the first bracket 7 and the second bracket 8.

[0063] The two columns 10 support on one side of the tire in the axial direction to prevent the tire from tipping over.

[0064] A tire disassembly and assembly auxiliary device in this embodiment can realize the transfer, installation, disassembly, etc. of the tire. The operation process during use is as follows:

[0065] Power on and confirm the device. After confirming that all wiring is normally connected, manually press the power switch. The power switch display light lights up, confirming that the device can be normally powered on. Then rotate the emergency stop button until the emergency stop button pops up, and the device resets to the working mode. Manually click the jog-out button and the jog-in button to confirm that the telescopic drive mechanism 3 can normally extend and retract. At the same time, adjust the speed control knob to adjust to a suitable operating speed.

[0066] Tire transfer. When transferring the tire, it is necessary to use other tools (such as a crane, jib crane, forklift, etc.) to place the tire in an upright state on the ground. The operator pushes the tire disassembly and assembly auxiliary device by hand, and it can move in any direction under the action of the universal wheels 4. Manually click the jog-out button or the jog-in button, and the telescopic drive mechanism 3 extends or shortens. Adjust the distance between the two tire guiding and supporting platforms 1 to be slightly larger than the tire size. Then push the tire disassembly and assembly auxiliary device so that the two tire guiding and supporting platforms 1 move to both sides of the tire (the tire rolling direction). Manually click the jog-in button, and the telescopic drive mechanism 3 shortens. The two tire guiding and supporting platforms 1 approach each other. As the two tire guiding and supporting platforms 1 clamp, the tire is continuously lifted. After the tire is lifted to a suitable size off the ground, the tire disassembly and assembly auxiliary device can be pushed to transfer the tire.

[0067] Tire installation. On the basis of the above tire transfer operation, push the tire disassembly and assembly auxiliary device to align the installation holes of the tire hub with the bolts of the vehicle rim basically. When the hub and the rim are approaching, according to the relative position of the installation holes of the tire hub and the bolts of the vehicle rim, manually click the jog-out button or the jog-in button, and the telescopic drive mechanism 3 extends or shortens to make the two tire guiding and supporting platforms 1 approach or move away from each other to adjust the height of the tire to a suitable position. When all the installation holes of the tire hub are aligned with the bolts of the vehicle rim, gently push the tire installation auxiliary device. All the installation holes of the tire hub pass through all the bolts of the vehicle rim, and then the tire is translated to the installation position, and the installation nuts are tightened.

[0068] Tire disassembly. First, lift one side of the tire to be removed with the help of other equipment (such as a crane, jack, etc.) and provide effective support to lift the tire off the ground. At the same time, remove the locking nuts of the tire. Push the tire disassembly and assembly auxiliary equipment to move the tire guiding support platform 1 under the tire. Manually click the jog-out button or jog-in button, and the telescopic drive mechanism 3 extends or retracts to make the two tire guiding support platforms 1 approach or move away from each other, so as to adjust the height of the tire to a proper position so that the mounting holes of the tire hub are basically aligned coaxially with the bolts of the vehicle rim, ensuring that there is no contact between the mounting holes of the tire hub and the bolts of the vehicle rim. At this time, gently push the tire disassembly and assembly auxiliary equipment to move the tire away from the vehicle rim.
