Description

Technical Field

[0001] This application relates to the field of tire removal and installation, and in particular to a tire stripping machine drive. Background Technology

[0002] After a vehicle has traveled a certain mileage, the tires may be punctured or damaged due to road debris, aging, or impacts. In this case, the tires need to be removed from the rims, the damaged areas inspected, and repaired or replaced.

[0003] Traditional tire removal methods include manual tire removal and mechanical tire removal. Manual tire removal relies on pry bars and manpower, which is inefficient and can easily damage the rim, making it only suitable for emergency situations. Mechanical tire removal uses a tire stripper to separate the tire from the rim. A tire stripper is a specialized piece of equipment used for removing and installing tires, and is widely used in auto repair shops, tire shops, and logistics fleets.

[0004] Tire stripping machines consist of a main frame and a turntable. The turntable is rotatably connected to the main frame, and clamps are attached to the turntable. The turntable is used to support and rotate the wheel hub, and the clamps are used to fix the wheel hub. The turntable is usually driven by an asynchronous motor. It can only control the turntable to stop, start, rotate forward or backward, and cannot dynamically adjust the speed according to the tire resistance. This can easily lead to tire bead tearing or wheel hub scratches, making it inconvenient for users to use. Utility Model Content

[0005] To facilitate user operation, this application provides a tire stripping machine drive device.

[0006] The tire stripping machine drive device provided in this application adopts the following technical solution:

[0007] A tire stripping machine drive device includes a mounting platform, a support plate, a fastening platform, a reducer, and a servo motor. The support plate is fixedly connected to the lower end of the mounting platform. A rotating column is fixedly connected to one side of the fastening platform. The mounting platform has a rotating opening. The rotating column is rotatably connected to the inner wall of the rotating opening around its own axis. The housing of the reducer is fixedly connected to the lower end of the mounting platform. The output shaft of the reducer is coaxially fixedly connected to the rotating column. The motor housing of the servo motor is fixedly connected to the mounting platform. The motor shaft of the servo motor is coaxially fixedly connected to the input shaft of the reducer.

[0008] By adopting the above technical solutions, stepless speed regulation and real-time torque control can be achieved, reducing tire damage, extending equipment service life, and making it easier for users to operate.

[0009] Preferably, it also includes a controller, which is fixedly connected to the mounting platform and electrically connected to the servo motor.

[0010] By adopting the above technical solution, the controller facilitates the adjustment of the fastening platform speed, reduces tire damage, extends the service life of the equipment, and makes it easier for users to operate.

[0011] Preferably, the device further includes an operating component, which includes a base, a main pedal, a permanent magnet, and a Hall sensor. The base is fixedly connected to a support plate, and a hinge seat is fixedly connected to the upper end of the base. A hinge column is fixedly connected to one end of the main pedal, and the hinge column is rotatably connected to the hinge seat around its own axis. The permanent magnet is coaxially fixedly connected to the hinge column, and the Hall sensor is fixedly connected to the base and electrically connected to the controller.

[0012] By adopting the above technical solution, when the user steps on the main pedal, the hinge column rotates, and the permanent magnet rotates synchronously, changing its relative position and angle with the Hall sensor on the base. The Hall sensor detects the change in magnetic field in real time, outputs an analog voltage signal proportional to the magnetic field strength, and transmits the signal to the controller to control the motor speed, making it convenient for the user.

[0013] Preferably, the operating component further includes a torsion spring, which is sleeved on the outer periphery of the hinge post. One end of the torsion spring is fixedly connected to the outer wall of the hinge post, and the other end of the torsion spring is fixedly connected to the hinge seat.

[0014] By adopting the above technical solution, the torsion spring enables the main pedal to automatically reset, making it convenient for users to operate even when the servo motor stops working.

[0015] Preferably, it also includes a sponge, which is disposed between the base and the main pedal, and is fixedly connected to the base. The sponge is used to abut against the main pedal.

[0016] By adopting the above technical solution, the sponge supports the base, reducing the damage caused by prolonged stress on the torsion spring, extending the service life of the torsion spring, and making it easier for users to use.

[0017] Preferably, the support plate has an operating port, and the end of the main pedal away from the hinge seat is located on the outer periphery of the support plate, with the main pedal passing through the operating port.

[0018] By adopting the above technical solution, the main pedal extends out of the operating port, making it convenient for users to step on and use.

[0019] Preferably, it also includes a clamping block. The fastening platform is provided with a sliding port. There are multiple sliding ports, which are evenly spaced around the axis of the rotating column. The clamping block is slidably connected to the inner wall of the sliding port.

[0020] By adopting the above technical solution, multiple clamping blocks slide to clamp the tire, thereby improving clamping efficiency.

[0021] Preferably, it further includes a turntable, a traction plate, and a push block. The turntable is coaxially rotatably connected to the outer wall of the rotating column. One end of the traction plate is hinged to the turntable, and the other end of the traction plate is hinged to the push block. The push block is fixedly connected to the clamping block. Multiple traction plates are provided, and the traction plates and clamping blocks are arranged in a one-to-one correspondence. The multiple traction plates are evenly spaced around the axis of the rotating column.

[0022] By adopting the above technical solution, the rotation of the traction plate facilitates the simultaneous control of the movement of multiple clamping blocks, improving clamping efficiency and making it easier for users to operate.

[0023] Preferably, it further includes a fixed plate and a drive cylinder, wherein the fixed plate is fixedly connected to the outer wall of the rotating column, the cylinder body of the drive cylinder is fixedly connected to the fixed plate, and the piston rod of the drive cylinder is fixedly connected to a push block.

[0024] By adopting the above technical solution, the driving source is reduced. Only one pusher needs to be controlled to control the sliding of all clamping blocks, reducing resource waste and making it easier for users to use.

[0025] Preferably, the upper surface of the fastening platform is provided with a scale mark, which is set along the length direction of the sliding opening and is used to mark the distance to the axis of the rotating column.

[0026] By adopting the above technical solution, it is easy to observe and adjust the movement distance of the clamping block, making it convenient for users.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Achieve stepless speed regulation and real-time torque control, reduce tire damage, extend equipment service life, and facilitate user operation;

[0029] 2. When the user presses down the main pedal, the hinge column rotates, and the permanent magnet rotates synchronously, changing its relative position and angle with the Hall sensor on the base. The Hall sensor detects the change in magnetic field in real time, outputs an analog voltage signal proportional to the magnetic field strength, and transmits the signal to the controller to control the motor speed, making it convenient for the user.

[0030] 3. The rotation of the traction plate facilitates the simultaneous control of the movement of multiple clamping blocks, improving clamping efficiency and making it easier for users to operate. Attached Figure Description
