Description

Technical Field

[0001] This invention relates to the field of practical training technology, specifically a belt drive teaching and training platform with fault setting function. Background Technology

[0002] A belt drive teaching and training platform is a device specifically designed for teaching and experimentation, aiming to intuitively and clearly demonstrate the working principle, structural characteristics, performance parameters, and installation and debugging methods of belt drives. It is typically a modular and integrated platform.

[0003] The existing belt drive teaching and training platform requires physical reinstallation every time different training content is changed. Since the platform components are relatively heavy, this frequent disassembly and reassembly not only significantly increases the difficulty and labor intensity of equipment installation, but also makes it difficult and time-consuming to quickly switch and simulate multiple application scenarios. This ultimately leads to reduced teaching efficiency (too much class time is spent on installation) and impaired teaching effectiveness (limited student operating experience and scenario coverage).

[0004] In addition, when setting up training content before teaching, the existing training platforms may cause programmatic faults in their equipment due to the content they set. After the faults occur, the equipment will vibrate. When simulating faults such as belt breakage, the rigid connection and lack of buffer design of the transmission system of traditional equipment will cause the flange connection bolts to loosen, the oil seals and sealing rings to wear faster, the lubricating oil to leak, and the electrical wiring terminals to loosen due to vibration, resulting in poor contact or short circuit.

[0005] Therefore, a belt drive teaching and training platform with fault setting function was proposed to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a belt drive teaching and training platform with fault setting function, so as to solve the problems that have occurred in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a belt drive teaching and training platform with fault setting function, comprising a training platform, a protective cover installed on one side of the upper surface of the training platform, tool boxes symmetrically installed on one side of the middle of the training platform, a partition fixedly installed on the inner wall of the middle of the training platform near the upper surface of the tool boxes, a detection device installed on the inner wall of the training platform near the partition, a control panel installed on the side of the upper surface of the training platform away from the fault setting, and further comprising a multi-mode switching mechanical structure and a shock absorption damping mechanism; The multi-mode switching mechanical structure is installed on the partition plate and is used for the rapid adjustment of the training platform. The vibration damping mechanism is installed and is used for vibration damping when the training platform is working.

[0008] Preferably, the multi-mode switching mechanical structure includes a guide groove, which is symmetrically opened on a partition plate. A limit groove is symmetrically opened on the partition plate near the inner side of the guide groove. A limit slide rail is fixedly installed on the upper surface of the training platform near the middle of the guide groove and the limit groove. A slide table is symmetrically slidably installed on the limit slide rail.

[0009] Preferably, the multi-mode switching mechanical structure further includes a rotating wheel, which is symmetrically rotatably mounted on the lower surface of the partition. A positioning transmission belt is driven on the outer surface of the rotating wheel, and a fixing clamp is symmetrically fixedly mounted on the positioning transmission belt.

[0010] Preferably, a connecting block is fixedly installed at the end of the fixed clamp away from the positioning transmission belt, the upper surface of the connecting block is fixedly installed on the slide table, and the outer surface of the connecting block is slidably installed in the limiting groove.

[0011] Preferably, the simulation mechanism includes a shaft drive platform and a gear drive platform, which are slidably mounted on the upper surface of the slide, and a movable drive platform is installed on the training platform near the side of the shaft drive platform.

[0012] Preferably, a training drive motor is installed on the upper surface of the movable drive platform, and an extrusion guide column is fixedly installed on the lower surface of the shaft transmission platform and the gear transmission platform. The outer surface of the extrusion guide column is slidably installed in the limiting slide rail.

[0013] Preferably, the shock absorption damping mechanism includes a first damping block and a second damping block. The slide table has a vibration damping groove on the side near the partition. A slide rail plate is fixedly installed in the middle of the vibration damping groove. The first damping block and the second damping block are symmetrically slidably installed on the outer surface of the slide rail plate.

[0014] Preferably, pressure blocks are rotatably mounted at both ends of the first and second damping blocks, and ball bearings are slidably mounted on the pressure blocks. A first damping rod and a second damping rod are symmetrically fixedly connected to the second and first damping blocks, respectively.

[0015] Preferably, the first damping rod is slidably mounted on the first damping block at one end away from the second damping block, and the second damping rod is slidably mounted in the second damping block at one end away from the first damping block. A return spring is sleeved on the outer surface of the second damping rod, one end of which is fixedly mounted on the first damping block, and the other end of which is fixedly mounted on the second damping block.

[0016] Compared with the prior art, the belt drive teaching and training platform with fault setting function provided by the present invention has the following beneficial effects: 1. Multi-mode rapid switching structure revolutionizes traditional inefficient processes. When switching transmission modes (such as shaft drive / gear drive) on existing training platforms, manual disassembly and reassembly of components and repeated position calibration are required, which takes up to 20 to 30 minutes. This solution uses a motor-driven rotary wheel with a sensor positioning belt to switch the slide position accurately within 90 seconds through a multi-mode switching mechanical structure, which improves the efficiency of teaching preparation by 300% and solves the problem of wasted course time due to manual operation.

[0017] 2. Integrated vibration damping mechanism overcomes persistent vibration interference problems. Traditional equipment, when simulating faults such as belt breakage, suffers from severe vibrations due to the rigid connection and lack of buffering in the transmission system, resulting in data acquisition errors exceeding 15%. This solution employs a triple vibration reduction design: sliding energy dissipation of damping blocks, vibration direction conversion by pressure block ball bearings, and residual impact absorption by a return spring and rubber vibration damping groove, suppressing the vibration amplitude to <2mm and ensuring the accuracy of fault test data.

[0018] 3. Modular platforms overcome the limitations of teaching scenarios. Existing technologies are limited by their single-function structure (such as supporting only a single transmission mode), making it difficult to simulate the complex transmission scenarios of shaft-gear-belt in real industry. This solution supports four linkage modes through the free combination of a detachable shaft transmission platform, a gear transmission platform, and a motor on a movable drive platform. Figure 5-7 This allows students to complete advanced practical training, from basic transmission to multi-level faults, on the same equipment.

[0019] 4. Intelligent control lowers the professional threshold for operation. Traditional equipment relies on manual debugging by teachers, which stems from the lack of human-computer interaction and low level of automation. This solution uses a preset program on the control panel to drive the sensor network (fixed clamp positioning + detection device monitoring) to automatically perform slide positioning and fault injection, enabling students to complete complex experiments independently and reducing teacher intervention costs by 80%.

[0020] 5. Compact design eliminates space and maintenance pain points. The most significant drawback of existing technology is its bulky and dispersed structure: the use of external shock absorbers, separate tool storage, and exposed transmission components increases the equipment's footprint by 40%, and vibrations easily cause external parts to detach (requiring maintenance twice a month). This problem stems from a non-integrated design mindset. This solution addresses this issue through three major innovations: Embedded vibration damping: The damping mechanism is fully integrated into the vibration damping groove of the slide to avoid external collisions; Integrated storage: Tool boxes and shelves are integrated into the training table, reducing the floor space by 50%; Enclosed operation: The protective cover covers the transmission components, which can prevent personnel injuries caused by splashing equipment parts, while reducing the maintenance requirement to 0.5 times / semester.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example 1, please refer to Figures 1 to 9 As shown: To address the problems mentioned in the technical solutions, this application provides a belt drive teaching and training platform with fault setting function, including a training platform 1. A protective cover 11 is installed on one side of the upper surface of the training platform 1. Tool boxes 14 are symmetrically installed on one side of the middle of the training platform 1. A partition 12 is fixedly installed on the inner wall of the middle of the training platform 1 near the upper surface of the tool box 14. A detection device 13 is installed on the inner wall of the training platform 1 above the partition 12. A control panel 15 is installed on the side of the upper surface of the training platform 1 away from 1. It also includes a multi-mode switching mechanical structure 2 and a shock absorption damping mechanism 4. The multi-mode switching mechanical structure 2 is set on the partition 12 and is used for the rapid adjustment of the training platform. The vibration damping mechanism 4 is installed and is used for vibration damping when the training platform is working. Specifically, guide grooves 21 are symmetrically opened on partition plate 12, and limit grooves 23 are symmetrically opened on the inner side of partition plate 12 near guide grooves 21. Limit slide rails 22 are fixedly installed on the upper surface of training platform 1 near the middle of guide grooves 21 and limit grooves 23. Slide tables 24 are symmetrically slidably installed on limit slide rails 22. Rotary wheels 29 are symmetrically rotatably installed on the lower surface of partition plate 12. Positioning transmission belts 27 are driven on the outer surface of rotary wheels 29. Fixed clamps 26 are symmetrically fixedly installed on positioning transmission belts 27. A connecting block 25 is fixedly installed on the end of fixed clamps 26 away from positioning transmission belts 27. The upper surface of connecting block 25 is fixedly installed on slide table 24, and the outer surface of connecting block 25 is slidably installed in limit grooves 23. Among them, the guide groove 21 is V-shaped to simulate the alternating switching of mechanism 3, and at the same time... Figure 3 As shown, the drive motor is installed in the middle of the rotating wheel 29. The rotation of the drive motor can drive the rotating wheel 29 to rotate. A sensing and positioning device is installed on the fixed clamping plate 26 and is electrically connected to the drive motor. It is used to control the position of the slide table 24 on the partition plate 12 by controlling the transmission action of the positioning transmission belt 27, thereby realizing the switching of the position of the slide table 24.

[0026] Specifically, the shaft drive platform 31 and the gear drive platform 32 are slidably mounted on the upper surface of the slide table 24, and a movable drive platform 33 is installed on the training table 1 near the side of the shaft drive platform 31; a training drive motor is installed on the upper surface of the movable drive platform 33, and an extrusion guide column 28 is fixedly installed on the lower surface of the shaft drive platform 31 and the gear drive platform 32, and the outer surface of the extrusion guide column 28 is slidably mounted in the limit slide rail 22; The slide table 24, via transmission on the partition 12, can control the change to multiple postures, including, for example... Figure 4 As shown, the transmission simulation of the drive motor on the 1-axis transmission platform 31 and the movable drive stage 33 is demonstrated. like Figure 6 As shown; 2. Practical training and transmission simulation of the drive motor on the gear transmission platform 32 and the movable drive stage 33; like Figure 5 As shown; The drive motor on the movable drive platform 33 and the shaft transmission platform 31 are linked through the belt and gear transmission platform 32 to simulate belt transmission and gear transmission in the training test. like Figure 7 As shown; 4. A training and testing platform for movable drive platform 33 and gear transmission platform 32 via shaft transmission; It should be noted that when switching between different scenarios, the shaft and belt need to be installed accordingly for experimental simulation. The shaft transmission platform 31 consists of a transmission shaft and a transmission wheel support; the gear transmission platform 32 consists of a gearbox, a transmission shaft, a transmission wheel, and a support; and the movable drive platform 33 is slidably mounted on the partition 12 by adjusting the nuts.

[0027] This solution enables rapid switching between different training platform modes through simple motor drive and sensor control. Compared to traditional simulation platforms that require staff to install and place the training vehicle before training and then debug and simulate, this solution only requires simple control through the control panel 15 to switch between different modes. It is not only easy to operate, but also more advantageous for simulating large-scale experiments. It can also adapt to different scenarios and be designed quickly, which is conducive to the rapid conduct of experiments.

[0028] Specifically, a vibration damping groove 41 is provided on the side of the slide table 24 near the partition plate 12. A slide rail plate 42 is fixedly installed in the middle of the vibration damping groove 41. The first damping block 43 and the second damping block 47 are symmetrically slidably installed on the outer surface of the slide rail plate 42. Pressure blocks 44 are rotatably installed at both ends of the first damping block 43 and the second damping block 47. Ball bearings are slidably installed on the pressure blocks 44. A first damping rod 45 and a second damping rod 46 are symmetrically fixedly connected to the second damping block 47 and the first damping block 43, respectively. The end of the first damping rod 45 away from the second damping block 47 is slidably installed on the first damping block 43. The end of the second damping rod 46 away from the first damping block 43 is slidably installed in the second damping block 47. A return spring 48 is sleeved on the outer surface of the second damping rod 46. One end of the return spring 48 is fixedly installed on the first damping block 43, and the other end of the return spring 48 is fixedly installed on the second damping block 47. In this design, a buffer damping device is installed at the bottom of the slide table 24, such as... Figure 9As shown, when the simulated training begins, the transmission will vibrate due to the fault type set. To ensure the stability of the training platform, this solution uses the buffer of the pressure block 44 to drive the first damping block 43 to slide on the slide rail plate 42. The first damping rod 45 and the second damping rod 46 guide the sliding of the second damping block 47, and the return spring 48 can be used to quickly return the pressure block 44 to its original position. When the first damping rod 45 and the second damping rod 46 are subjected to strong vibration, the pressure block 44 drives the first damping block 43 to slide, which can compress and dampen the inner wall of the vibration damping groove 41. The inner wall of the vibration damping groove 41 is set with rubber buffer pads. The sliding collision of the first damping rod 45 and the second damping rod 46 can achieve vibration damping. At the same time, the rubber buffer pads can absorb the mechanical vibration of the collision between the first damping rod 45 and the second damping rod 46, which is conducive to the stability of the training platform and reduces the mechanical damage caused by equipment vibration.

[0029] The specific implementation steps are as follows: Example 2: The drive motor and shaft transmission platform 31 are used for shaft transmission training simulation. like Figure 3 As shown, first, turn on the power control switch on the control panel 15, and simultaneously start the drive motor located on the lower surface of the partition 12. At this time, the positioning sensor on the fixed clamp 26 controls the transmission distance of the positioning transmission belt 27 by controlling the rotation of the motor. Then, by controlling the sliding of the connecting block 25 fixedly installed at the bottom of the slide 24, the slide 24 at the bottom of the gear transmission platform 32 slides to the guide groove 21 near the end of the movable drive platform 33. At this time, the positioning sensor automatically controls the drive motor to stop rotating after monitoring. At the same time, the operator installs the prepared transmission shafts on the drive motor of the movable drive platform 33. After adjusting the position of the movable drive platform 33 by loosening the positioning nut on the movable drive platform 33, the transmission shaft is then installed on the transmission shaft of the gear transmission platform 32 through the connector to realize the training simulation of shaft transmission.

[0030] Example 3 differs from Example 2 in that it is designed as a gear meshing training simulation. like Figure 6As shown, first, turn on the power control switch on the control panel 15, and simultaneously start the drive motor located on the lower surface of the partition 12. At this time, under the control of the positioning sensor on the fixed clamp 26 and the programmed settings of the terminal, the transmission distance of the positioning transmission belt 27 is controlled by controlling the rotation of the motor. Then, by controlling the sliding of the connecting block 25 fixedly installed at the bottom of the control slide 24, the slide 24 at the bottom of the shaft transmission platform 31 slides to the guide groove 21 near the end of the movable drive platform 33. At this time, the positioning sensor automatically controls the drive motor to stop rotating after monitoring. At the same time, the operator installs the prepared transmission shafts on the drive motor of the movable drive platform 33. After adjusting the position of the movable drive platform 33 by loosening the positioning nut on the movable drive platform 33, the transmission shaft is then installed on the transmission shaft of the shaft transmission platform 31 through the connector to realize the training simulation of gear transmission.

[0031] Example 4 differs from Example 3 in that it is designed as a training simulation of gear meshing and belt and shaft transmission. like Figure 5 As shown, under the control of the drive motor at the bottom of the partition 12, the shaft drive platform 31 and the gear drive platform 32 slide along the upper surface of the slide table 24 after being squeezed by the mutual squeezing action of the squeeze guide post 28 and the limiting groove 23. When the positioning drive belt 27 drives the slide table 24 to be parallel to each other, the motor stops rotating through the program design. At this time, as shown... Figure 5 As shown, the transmission belts are installed on the transmission wheels of the shaft transmission platform 31 and the gear transmission platform 32 respectively. At the same time, the movable drive platform 33 is adjusted to be in the same straight line as the three axes. When the transmission shaft is installed, the movable drive platform 33 and the transmission shaft of the shaft transmission platform 31 drive each other. The motor drive of the movable drive platform 33 can drive the shaft on the shaft transmission platform 31 to rotate, drive the transmission disk to drive the transmission belt, and realize the gear transmission linkage simulation on the gear transmission platform 32.

[0032] Table 1 presents a statistical summary of the solutions offered in this scheme compared to existing technologies.

[0033] This solution improves teaching efficiency by 300% through mechatronics design, as calculated in the example, while extending equipment life by more than 30%. The shock absorption mechanism reduces parts wear and tear, meeting the core needs of modern vocational education for efficient, safe, and multi-scenario practical training.
