Description

Technical Field

[0001] The present invention relates to the technical field of torque and electricity multiplication devices, and in particular to a wheel-type torque and electricity multiplication device. Background Art

[0002] Wheel-type torque and power multiplier devices primarily utilize a motor-driven gearbox, which in turn increases traction through a power wheel, driving a large-diameter rotor. Rotation of the large-diameter rotor delivers greater torque through the load center axis, saving effort and achieving high economic benefits. However, before the large-diameter rotor begins to rotate, static friction must be overcome, which is greater than the sliding friction during rotation. Therefore, a tensioning mechanism, assisted by a reduction gearbox, is required at the beginning of rotation to prevent belt slippage and maintain high torque to drive the large-diameter rotor. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention aims to provide a wheel-type torque and power multiplier device to solve the technical problem that the wheel-type torque and power multiplier device in the prior art compresses the tension wheel at the beginning of rotation, and the reduction box generates a large torque, which causes the belt to slip easily and the wheel cannot rotate. At the same time, it solves the technical problem of torque conversion generated by the central axis of the lever, gravity, and inertia force during the rotation of the wheel-type torque and power multiplier device.

[0004] In order to solve the above technical problems, the present invention provides a wheel-type torque and power generation device, which includes a frame, a rotating wheel, a driving mechanism and a power system. The rotating wheel is rotatably connected to the frame through a rotating shaft. The driving mechanism includes a belt, a power wheel, a reduction gear and a motor. The power wheel is rotatably connected to the frame. The motor is connected to the frame through a reduction gear and drives the power wheel to rotate. The belt is wrapped around the rotating wheel and the power wheel. The power system includes a generator, a speed increaser and a universal joint. The generator is connected to the frame, the generator is connected to the universal joint through the speed increaser, the universal joint is connected to the flange, and the flange is connected to the rotating shaft.

[0005] After adopting the above structure, the wheel-type torque and power generation device of the present invention has the following advantages: the motor in the driving mechanism drives the power wheel to rotate through the reduction gearbox, and the power wheel drives the rotary wheel to rotate through the belt to output a large torque. At the beginning of the rotation, the motor in the driving mechanism drives the rotary wheel to rotate, and the large-diameter rotary wheel is adjusted by the flange, universal joint and speed increaser. After the rotary wheel rotates, the universal joint realizes variable-angle force transmission and there is a speed difference between the rotation speed of the rotary wheel and the output speed of the gearbox. Only the driving mechanism drives the rotary wheel to rotate, thereby achieving the effect of saving energy.

[0006] As improvement, at least one set of tensioning structure is connected on the rack, the tensioning structure comprises a tensioning wheel, a slide rail and a driving member, the slide rail is connected on the rack, the tensioning wheel is slidingly connected on the slide rail, the driving member is connected with the rack and drives the tensioning wheel to slide, and the tensioning wheel abuts against the belt; by adopting the structure, the driving member drives the tensioning wheel to move so as to tension the belt, and the belt slip is prevented, and according to different working conditions, the driving member can drive the tensioning wheel to move to different positions to adjust the tension of the belt.

[0007] As improvement, two sets of tensioning structure are connected on the rack, and the tensioning wheels in the two sets of tensioning structure abut against the belts on both sides of the power wheel respectively; by adopting the structure, the belt slip is further prevented.

[0008] As improvement, the small-diameter runner belt is a common belt (the belt material is determined according to the actual size, for example, the canvas belt can be woven according to the actual size); by adopting the structure, the canvas belt can meet the requirement of the length of the belt in the application scenario of the large-diameter runner.

[0009] As improvement, the runner diameter is greater than or equal to 2 m; by adopting the structure, the runner output torque is larger under the size, and the economic benefit is higher.

[0010] As improvement, the flange, the universal joint and the speed increasing box are connected at one end of the shaft for connecting with the load.

[0011] As improvement, the wrap angle α of the belt to the power wheel is greater than or equal to 120°; by adopting the structure, the belt slip is further prevented. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0017] The application wheel type torque output device will be described in detail below with reference to the drawings.

[0018] like Figures 1 to 4 As shown, the wheel-type torque output device includes a frame 1, a wheel 2, a drive mechanism 3 and a power generation system 4. The wheel 2 is rotatably connected to the frame 1 through a shaft 5. That is, the shaft 5 is rotatably connected to the frame 1, and the center of the wheel 2 is connected to the shaft 5 and rotates synchronously with the shaft 5; Figure 1 and Figure 2 As shown, one end of the rotating shaft 5 is connected to a flange for connecting to a load, a generator, a speed increaser and a universal joint.

[0019] like Figure 1 and Figure 2 As shown, the driving mechanism 3 includes a belt 31, a power wheel 32, a reduction gear box 34 and a motor 33. The power wheel 32 is rotatably connected to the frame 1. In this embodiment, the power wheel 32 is located at the lower right corner of the belt 31. The motor 33 is connected to the frame 1 through the reduction gear box 34 and drives the power wheel 32 to rotate. The motor 33 is also connected to the starting inverter 8. The belt 31 is wound around the rotating wheel 2 and the power wheel 32. Figure 4 As shown, at least one set of tensioning structures 6 is connected to the frame 1, and the tensioning structure 6 includes a tensioning wheel 61, a slide rail 62 and a driving member 63. The slide rail 62 is connected to the frame 1, and the tensioning wheel 61 is slidably connected to the slide rail 62. The driving member 63 is connected to the frame 1 and drives the tensioning wheel 61 to slide, and the tensioning wheel 61 is against the belt 31; Figure 2 and Figure 4 As shown, in this embodiment, two sets of tensioning structures 6 are connected to the frame 1, and the tensioning wheels 61 in the two sets of tensioning structures 6 are respectively against the belts 31 on both sides of the power wheel 32. Specifically, the tensioning wheels 61 in the two sets of tensioning structures 6 slide in the horizontal direction. Preferably, the tensioning wheels 61 are not only slidingly connected to the slide rail 62, but also rotationally connected to the slide rail 62, and the driving member 63 is a hydraulic system.

[0020] like Figure 2 and Figure 3 As shown, the wrap angle α of the belt 31 to the power wheel 32 is greater than or equal to 120°. To prevent the belt 31 from slipping, the upper tensioning wheel 61 moves to the left, and the lower tensioning wheel 61 moves to the right, so that the wrap angle α of the belt 31 to the power wheel 32 increases. Conversely, the upper tensioning wheel 61 moves to the right, and the lower tensioning wheel 61 moves to the left, so that the wrap angle α of the belt 31 to the power wheel 32 decreases.

[0021] like Figure 1 As shown, the power generation system 4 includes a generator 41, a speed increaser 42, a universal joint 43 and a flange 7. The generator 41 is connected to the frame 1. The generator 41 is connected to the universal joint 43 through the speed increaser 42. The universal joint 43 is connected to the flange 7, and the flange 7 is connected to the rotating shaft 5.

[0022] In this embodiment, the diameter of the wheel 2 is greater than or equal to 2m. In order to meet the use requirements of the small diameter wheel 2, the length of the belt 31 also needs to be adaptively increased. The belt 31 is an ordinary belt. When a canvas belt is used, it is adjusted according to the diameter of the wheel 2 to prevent the belt 31 from slipping.

[0023] The following is an example of a runner 2 with a diameter of 3m. The diameter of the shaft 5 is 0.095m, and the speed increaser 42 (gear radius + gear radius + gear radius + gear radius) is 0.05m + 0.05m + 0.05m + 0.05m = 0.2m. Therefore, the lever magnification is the radius of the runner 2 ÷ the diameter of the shaft 5, and the leverage ratio is 1.5m - 0.095m - 0.2m = 1.205m. The runner 2 weighs 491kg, and its gravity is about 4812N. The torque obtained by the gravity of the runner 2 * the leverage ratio is 4812N * 12.05 = 57984.6N, and the drive runner 2 The traction force for rotation is the gravity of the runner 2 ÷ (the radius of the runner 2 - the diameter of the shaft 5 - the radius of the reduction gear and 0.2m). The required traction force is 4812N ÷ (1.5m-0.095m-0.2m) = 3993.361N. From the above derivation formula, it can be obtained that for the runner 2 with a diameter of 3m and a weight of 491kg, only 3993.36N of traction is required to output 57984.6N of torque, which greatly improves the output torque and has high economic benefits. The input traction force must be guaranteed to be above 3993.36N, and the load driven by the runner 2 must be below 57984.6N.

[0024] The motor 33 in the driving mechanism 3 drives the power wheel 32 to rotate, and the power wheel 32 drives the wheel 2 to rotate through the belt 31 to output a large torque. At the beginning of the rotation, the motor 33 and the reduction gear 34 in the driving mechanism 3 are started to drive the wheel 2 to rotate, which can output a large torque and achieve low speed and high torque. At the beginning of the rotation of the wheel 2, the auxiliary wheel 2 rotates, and the two tensioning wheels 61 are moved to a suitable tightness position to prevent the belt 31 from slipping, ensuring that the wheel 2 can start normally. After the wheel 2 rotates and there is a speed difference between the speed of the wheel 2 and the output speed of the speed increaser 42, the universal joint 43 enables the speed increaser 42 and the shaft 5 to change the angle of power transmission to achieve the number of revolutions required for the normal operation of the generator. The wheel 2 is only driven to rotate by the driving mechanism 3, thereby achieving the effect of saving energy. At this time, the positions of the two tensioning wheels 61 are appropriately adjusted to ensure that the belt 31 is appropriately tensioned, so that the device can operate normally as a whole.

[0025] The above describes the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned embodiment. All other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.
