Description

Technical Field

[0001] The present invention relates to the field of acceleration devices, and in particular to a high-acceleration system with a flexible and fast arrangement. Background Art

[0002] At present, common acceleration devices mainly include electric acceleration. Electric acceleration accelerates the load by driving the load with a variable frequency motor. The time required to accelerate the load to the specified speed varies depending on the load size, which can meet a wide load range. However, the larger the load, the longer the time required. For some specific occasions, such as quickly responding to large loads within a confined space and performing actions such as lifting, pulling or intercepting the load, the above-mentioned existing acceleration devices are difficult to respond quickly in a very short time and the equipment installation space is limited. Based on this, the following improvements are proposed. Summary of the Invention

[0003] The present invention is intended to provide a mobile and fast-arranged high-acceleration system to solve the problem of being unable to reach a high-acceleration state in response to a large load.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a mobile and fast-arranged high-acceleration system, including a frame, a rotating part for connecting a load is rotatably provided on the frame, and a variable frequency motor is also provided. The rotating part rotates coaxially with the variable frequency motor, and a rotating shaft is rotatably provided on the frame. The output end of the variable frequency motor is coaxially connected to the rotating shaft. The variable frequency motor drives the rotating part to rotate through the rotating shaft. An energy storage part is provided at the rotating shaft between the variable frequency motor and the rotating part. The energy storage part includes several flywheel assemblies coaxially arranged on the rotating shaft. The flywheel assembly includes a base wheel coaxially arranged on the rotating shaft and several sliding wheels coaxially slidably arranged on the rotating shaft. The frame is also slidably provided with a support part. The several sliding wheels are detachably connected to the base wheel and the support part. The support part is used to make the sliding wheel suspend in the air.

[0005] The beneficial effects of this solution are: the high rotational inertia characteristics of the flywheel assembly enable it to respond quickly and store energy during the acceleration process of the variable frequency motor. When the variable frequency motor needs to accelerate, the flywheel can absorb and store energy, thereby reducing the instantaneous power demand of the variable frequency motor and reducing the load pressure of the variable frequency motor. This characteristic is particularly important in electric vehicles, industrial variable frequency motors and energy storage systems, because these systems usually need to provide high power output in a short time. In contrast, traditional pneumatic or electromagnetic drive systems often require a larger variable frequency motor volume or higher current input at high speed and high load to meet the instantaneous power demand, and the flywheel assembly can achieve this goal more efficiently.

[0006] Furthermore, under high-speed and high-load conditions, traditional variable-frequency motors require a large power input to maintain high-speed operation. Flywheel assemblies, by storing energy, can release it when the variable-frequency motor needs it, thereby reducing the motor's instantaneous power requirements. Flywheel assemblies, through their high moment of inertia, exhibit significant advantages in the field of variable-frequency motor acceleration. They not only improve the motor's acceleration performance and response speed, but also reduce its size and weight, lower its power requirements, and improve system stability. The flywheel assembly's high energy density and high-speed rotation-adaptable material design give it broad application prospects in a variety of application scenarios. Therefore, from the perspective of existing pneumatic and electromagnetic drive technologies, flywheel assemblies have irreplaceable advantages under high-speed and high-load conditions.

[0007] Preferably, as an improvement, a clutch is provided between the frame and the rotating member, and the clutch is used to connect or disconnect the power transmission between the variable frequency motor and the rotating member.

[0008] The beneficial effect is that the clutch can engage power transmission when needed, and disconnect the power connection between the engine and the transmission system when not needed, thereby achieving flexible control of power transmission. This control capability allows the equipment to adjust power output according to actual needs during operation, improving the adaptability and efficiency of the system.

[0009] Preferably, as an improvement, the rotating member is configured as a winch, the winch is used to wind a flexible member acting on a load, and the frame is provided with a first bracket for rotatably mounting the winch.

[0010] The beneficial effect is: by fixing the winch on the first bracket on the frame, it can be ensured that the winch will not cause safety hazards due to shaking or falling off during use. Especially in mobile equipment such as vehicles, the winch is usually installed on the outside. If it is not firmly fixed, it may loosen or even fall off during driving, causing danger. Setting a rotatable winch bracket can improve driving safety.

[0011] Preferably, as an improvement, the clutch includes an inner cylinder and an outer cylinder which are arranged to rotate with each other, the frame is provided with a second bracket for rotating the inner cylinder of the clutch, the clutch is placed on the inner ring of the capstan and the outer cylinder is fixedly connected to the inner ring of the capstan, and the inner cylinder is connected to the rotating shaft.

[0012] The beneficial effects are: by placing the clutch on the inner ring of the capstan and fixedly connecting the outer cylinder to the inner ring of the capstan, the clutch can be installed compactly, space occupancy can be reduced, and integration into the mechanical system is facilitated. The direct connection between the inner cylinder and the rotating shaft makes power transmission more direct and efficient, which helps to reduce energy loss and improve overall transmission efficiency. The setting of the second bracket provides stable rotation support for the clutch inner cylinder, which helps to reduce vibration and wear and improve the stability of the transmission system. In addition, due to the relatively simple structural design of the clutch, it is easy to maintain and replace when needed, reducing maintenance costs and time.

[0013] Preferably, as an improvement, the rotating shaft includes a flywheel shaft for connecting to the energy storage part and a spline shaft for connecting to the clutch, and the flywheel shaft and the output shaft of the variable frequency motor, and the flywheel shaft and the spline shaft are coaxially connected through a coupling.

[0014] The beneficial effects are: by connecting the flywheel shaft to the output shaft of the variable frequency motor and the flywheel shaft to the spline shaft through a coupling, efficient power transmission can be achieved. The design of the coupling can reduce energy loss and ensure stable power transmission in the system; the coupling connection between the flywheel shaft and the output shaft of the variable frequency motor, as well as the connection between the flywheel shaft and the spline shaft, can effectively prevent structural loosening caused by axis deviation or vibration. This design helps to improve the stability and reliability of the entire system.

[0015] Preferably, as an improvement, the flywheel assembly also includes a conical disk fixed to the rotating shaft, and a clamping sleeve is connected between the base wheel and the flywheel shaft. The clamping sleeve is used to fix the base wheel to the rotating shaft and press against the end of the conical disk. The end with a larger diameter of the outer ring of the conical disk is equal to the tangent diameter of the inner ring of the sliding wheel.

[0016] The beneficial effects are: the expansion sleeve generates a clamping force between the inner ring of the base wheel and the flywheel shaft through high-strength tension bolts, thereby achieving a stable connection between the base wheel and the flywheel shaft. This connection method can effectively transmit torque and rely on pressure and friction to ensure the stability of the connection when bearing load. The installation of the expansion sleeve does not require heating, cooling or pressurizing equipment. It only needs to tighten the bolts to the required torque. The installation process is simple and quick.

[0017] In addition, the connection method of the expansion sleeve has low requirements on the processing accuracy of the shaft and the hub, which is convenient for manufacturing and assembly. The sliding wheel slides on the frame and places the conical disk in its inner ring. When the sliding wheel is connected to the base wheel, the inner ring of the sliding wheel is tangent to the outer ring of the larger end of the conical disk. At this time, the rotation of the rotating shaft can increase the stability of the rotation of the sliding wheel. When the sliding wheel is suspended on the frame through the support part, the inner ring of the sliding wheel does not contact the conical surface of the conical disk, and the selective connection of the flywheel can be realized.

[0018] Preferably, as an improvement, the sliding wheel is detachably connected to the base wheel by bolts.

[0019] The beneficial effect is that the bolt connection between the sliding wheel and the base wheel makes the sliding wheel easy to disassemble and install, thereby improving the maintainability of the equipment. This design not only simplifies the installation process, but also reduces maintenance costs.

[0020] Preferably, as an improvement, the support portion includes a slide rail fixed to the frame, a support frame slidably connected to the slide rail, the support frame and the sliding wheel are detachably connected by bolts, and the bottom end of the support frame is connected to a positioning bolt for abutting against the frame.

[0021] The beneficial effects are as follows: the support frame is slidably connected to the frame, and the position of the support frame on the frame can be adjusted according to the situation, so that the sliding wheels of different masses can be connected and fixed by bolts. The support frame and the sliding wheel are connected so that the sliding wheel is suspended relative to the rotating shaft and the conical disk. When the rotating shaft and the conical disk rotate, the sliding wheel connected to the support frame does not rotate. When the sliding wheel is connected, in order to ensure the stability of the structure, the support frame is fixed to the frame by the positioning bolt, so that the number of sliding wheels connected to the base wheel can be adjusted according to the load size, and it is ensured that the sliding wheels that are not connected do not rotate with it.

[0022] Preferably, as an improvement, the frame is slidably connected to a sliding seat, and the first bracket and the second bracket are both fixed to the sliding seat.

[0023] The beneficial effects are: the sliding seat realizes a sliding connection between the first bracket and the second bracket and the frame by fixing the first bracket and the second bracket. The sliding seat can move flexibly on the frame while maintaining the stability of the structure. When installing and disassembling the device, the position of the winch and the clutch on the frame can be adjusted by pushing the sliding seat. This design is not only easy to install, but also allows the position of the sliding seat to be adjusted under different working conditions to adapt to different usage requirements.

[0024] Preferably, as an improvement, the clutch inner cylinder is connected to the spline shaft.

[0025] The beneficial effects are: the spline shaft and the clutch inner cylinder are connected by splines, which can achieve smooth transmission and separation between the shafts. This connection method utilizes the multi-tooth structure of the spline to make the torque transmission more uniform, reduce the energy loss caused by sliding friction, and thus improve the transmission efficiency. In addition, the structural design of the spline connection enables the clutch to maintain good reliability during frequent engagement and disengagement. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example The embodiment is basically as shown in the attached Figures 1-6 As shown, Figure 1-Figure 3 The shown system is a mobile, fast-arranged, high-acceleration system, comprising a frame 1 at the bottom, a variable-frequency motor 11 fixedly mounted on the top of the frame 1, a frequency converter electrically connected to the variable-frequency motor 11, and the speed of the variable-frequency motor 11 is adjusted by the frequency converter. A flywheel shaft 21 is rotatably mounted on one side of the top of the frame 1 near the output end of the variable-frequency motor 11, the flywheel shaft 21 is coaxially arranged with the variable-frequency motor 11, and bearing seats are fixedly welded at both ends of the flywheel shaft 21 at the top of the frame 1. The two ends of the flywheel shaft 21 are rotatably mounted on the frame 1 through the bearing seats, and the flywheel shaft 21 and the output shaft of the variable-frequency motor 11 are fixedly connected by a coupling.

[0029] like Figure 2-Figure 4As shown, the flywheel shaft 21 is provided with an energy storage part 3, which includes a plurality of flywheel assemblies. The flywheel assembly includes a conical disk 33 welded coaxially fixed to the flywheel shaft 21, and a base wheel 31 fixedly mounted on the flywheel shaft 21. The inner ring diameter of the base wheel 31 is larger than the inner ring diameter of the flywheel shaft 21, and the inner ring diameter of the base wheel 31 is smaller than the outer ring diameter of the larger end of the conical disk 33. A tightening sleeve 311 is sleeved between the inner ring of the base wheel 31 and the flywheel shaft 21. The tightening sleeve 311 is fastened between the inner ring of the base wheel 31 and the flywheel shaft 21 by high-strength tension bolts. A clamping force is generated between the base wheel 31 and the flywheel shaft 21, thereby achieving a stable connection between the base wheel 31 and the flywheel shaft 21. This connection method can effectively transmit torque and rely on pressure and friction to ensure the stability of the connection when bearing load. During installation, the base wheel 31 is fixed to the flywheel shaft 21 through the expansion sleeve 311 and presses against the end face of the larger end of the conical disk 33. The flywheel assembly also includes several sliding wheels 32 that are axially slidably connected to the frame 1 along the flywheel shaft 21. The inner ring diameter of the sliding wheel 32 is the same as the outer ring diameter of the larger end of the conical disk 33.

[0030] The cam 32 is fixed to the frame 1 and the cam 32 is fixed to the frame 1 so that the cam 32 can rotate.

[0031] like Figure 2-Figure 4 As shown, the diameters of the sliding wheels 32 are different. Corresponding fixing holes are provided between the sliding wheels 32 and the base wheel 31. The base wheel 31 and the flywheel are also fixedly connected by bolts, so that the sliding wheels 32 with a mass corresponding to the load can be fixed on the base wheel 31 according to loads of different sizes. When the variable frequency motor 11 accelerates, the high rotational inertia characteristics of the flywheel assembly enable it to respond quickly and store energy, thereby reducing the instantaneous power demand of the variable frequency motor 11, and finally enabling the variable frequency motor 11 to quickly increase the speed of the flywheel shaft 21 to a high speed state. The frame 1 is fixedly provided with several positioning members on one side of the slide rail 41, and the bottom end of the bracket is connected to a positioning bolt 43 corresponding to the positioning member, and the support frame 42 is fixed to the frame 1 through the connection between the positioning bolt 43 and the positioning member.

[0032] The top of the frame 1 is located on both sides of the flywheel shaft 21 away from the variable frequency motor 11, and a slide groove is symmetrically opened on both sides. The top of the frame 1 is horizontally slidably connected to the sliding seat 5 through the slide grooves on both sides. The first bracket 51 and the second bracket 52 are fixedly welded on the sliding seat 5. The first bracket 51 and the second bracket 52 are symmetrically welded on both sides of the sliding seat 5. The top of the first bracket 51 is rotatably connected to the capstan 511, which is used to wind the flexible member acting on the load. The top of the second bracket 52 is installed with a clutch 6. The device 6 includes a spline shaft 22, and the clutch 6 includes an inner cylinder and an outer cylinder. The inner cylinder of the clutch 6 is connected to the spline shaft 22, and the outer cylinder of the clutch 6 is connected to the capstan 511. The spline shaft 22 is installed coaxially with the flywheel shaft 21. Bearing seats are also welded and fixed on both sides of the sliding seat 5. Both ends of the spline shaft 22 are rotatably mounted on the second bracket 52 through the bearing seats. The end of the spline shaft 22 close to the flywheel shaft 21 is also fixedly connected to the flywheel shaft 21 through a coupling. The flywheel shaft 21 and the spline shaft 22 together constitute the rotating shaft 2.

[0033] like Figure 5-Figure 6 As shown, the clutch 6 includes a hydraulic cylinder 61 fixedly mounted on the end of the spline shaft 22 away from the flywheel shaft 21, the hydraulic cylinder 61 is coaxially connected to the spline shaft 22, and also includes a roller 62 rotatably connected to the end of the spline shaft 22 close to the flywheel shaft 21, the roller 62 is coaxially arranged with the spline shaft 22, the hydraulic cylinder 61 and the roller 62 form a clutch 6 housing, the spline shaft 22 is located in the inner cavity of the housing and is connected to a plurality of brake discs 221 through the splines of the spline shaft 22, and a plurality of toothed discs 621 are arranged in the inner cavity of the clutch 6 at intervals from the brake disc 221, and the outer ring diameter of the toothed disc 621 is larger than that of the brake disc 221. The outer ring diameter, several grooves are symmetrically opened on both sides of the gear plate 621, and several pairs of grooves are arranged symmetrically with the center. The friction plate 6211 is fixedly installed in the groove. The outer ring of the gear plate 621 is opened with several teeth, and the inner wall of the drum 62 is opened with several tooth grooves corresponding to the outer teeth of the gear plate 621. Several tooth grooves axially span the inner wall of the drum 62. During installation, several gear plates 621 are meshed with the tooth grooves of the drum 62. The gear plate 621 and the brake disc 221 are arranged adjacent to each other, wherein the gear plate 621 and the drum 62 form the outer cylinder of the clutch 6, and the brake disc 221 hydraulic cylinder 61 forms the inner cylinder of the clutch 6.

[0034] The end of the hydraulic cylinder 61 is fixedly connected to an adapter 611, and a plurality of hydraulic oil circuits are opened inside the hydraulic cylinder 61. The hydraulic cylinder 61 is provided with a plurality of pistons 612 that slide axially along the spline shaft 22. When installed and driven, the adapter 611 is connected to the external hydraulic oil circuit, and the external hydraulic oil circuit drives the piston 612 to press against the gear plate 621 through the hydraulic oil, and the gear plate 621 drives the friction plate 6211 to press against the brake disc 221. The brake disc 221 and the gear plate 621 press against each other in turn, so that the friction plate 6211 on the gear plate 621 presses against the brake discs 221 on both sides. At this time, the friction force increases. When the spline shaft 22 drives the brake disc 221 to rotate, the friction plate 6211 also drives the gear plate 621 to rotate through friction, so that the gear plate 621 drives the drum 62 to rotate. A plurality of fixing plates are fixedly welded between the outer ring of the drum 62 and the inner ring of the capstan 511, so that the outer cylinder of the clutch 6 is fixedly connected to the capstan 511.

[0035] A plurality of first return rods 63 and second return rods 64 are fixedly connected between the hydraulic cylinder 61 in the inner cavity of the clutch 6 and the roller 62 along the axial direction of the spline shaft 22. The first return rods 63 and the second return rods 64 are both arranged parallel to the spline shaft 22. The plurality of first return rods 63 pass through the plurality of brake discs 221 in sequence, and the plurality of second return rods 64 pass through the plurality of toothed discs 621 in sequence. A first return spring is connected between the first return rod 63 and the plurality of brake discs 221 passed through, and a second return spring is connected between the second return rod 64 and the plurality of toothed discs 621 passed through. The first return rod 63, the first return spring, the second return rod 64, and the second return spring together constitute a return assembly. When the hydraulic cylinder 61 stops pushing the toothed disc 621, the first return spring and the second return spring respectively drive the brake disc 221 and the toothed disc 621 to reset, thereby disconnecting the inner cylinder from the outer cylinder.

[0036] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
