Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] As described in the background section, current methods for practicing construction project cost estimates primarily rely on traditional paper-based materials or electronic documents. However, the inventors have discovered that this method has significant shortcomings in terms of intuitiveness, dynamic interaction, and effectiveness.

[0026] Specifically, when using paper documents for drills, operators need to manually sift through a large amount of material to find the required data and information, resulting in a cumbersome process and low work efficiency. Furthermore, paper documents are inconvenient to store and update, making it difficult to adapt to continuous changes in engineering needs. Although electronic documents improve information storage capacity and retrieval efficiency to some extent, they still cannot provide a simulation environment that closely resembles real engineering scenarios, lacking an immersive and interactive training experience, resulting in poor drill effectiveness.

[0027] Based on this, please refer to Figures 1-8The present invention provides a construction project cost budgeting simulation device 100, which can effectively improve the aforementioned technical problems. Specifically, it can intuitively display the content of the budgeting simulation, dynamically adjust the simulation position to meet the simulation needs in different scenarios, and is simple and convenient to operate, improving work efficiency and simulation effectiveness. The construction project cost budgeting simulation device 100 will be described in detail below.

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of the construction project cost budgeting simulation device 100 provided in this embodiment. Figure 2 This is a partial structural schematic diagram of the construction project cost budgeting simulation device 100 provided in this embodiment. (Combined with...) Figure 1 and Figure 2 The construction project cost budgeting simulation device 100 includes a simulation frame 10, a simulation board 20, a roll material take-up and unwinding assembly 30, a lifting assembly 40, a drive mechanism, and a controller (not shown in the figure). The simulation frame 10 has a simulation space inside, the simulation board 20 is rotatably mounted on the simulation frame 10 and located in the simulation space, and the lifting assembly 40 is connected to the simulation frame 10.

[0029] For details, please refer to Figure 3 , Figure 3 This is an assembly diagram of the training board 20 and the roll material take-up and unwinding assembly 30 provided in this embodiment, combined with... Figures 1-3 The roll material unwinding assembly 30 includes an unwinding roller 31, a take-up roller 32, and a training roll 33. Both the unwinding roller 31 and the take-up roller 32 are rotatably mounted on the training plate 20. One end of the training roll 33 is connected to the unwinding roller 31, and the other end is connected to the take-up roller 32. The drive mechanism includes a first drive mechanism 50, a second drive mechanism 60, and a third drive mechanism 70. The first drive mechanism 50 is connected to the training plate 20, the second drive mechanism 60 is connected to both the unwinding roller 31 and the take-up roller 32, and the third drive mechanism 70 is connected to the lifting assembly 40. The controller is electrically connected to the first drive mechanism 50, the second drive mechanism 60, and the third drive mechanism 70 to control these mechanisms, thereby adjusting the rotation angle of the training plate 20, the unwinding and take-up speed of the training roll 33, and the height of the training frame 10.

[0030] In other words, by setting the second drive mechanism 60, the unwinding roller 31 and the take-up roller 32 can be driven to rotate relative to the training plate 20, thereby causing the training roll 33 to clearly and continuously display the training content on the training plate 20, improving the intuitiveness of operation. Furthermore, by setting the first drive mechanism 50, the training plate 20 can be driven to rotate relative to the training frame 10, enabling the training roll 33 to be displayed at different angles. And by setting the third drive mechanism 70, the training frame 10 can be driven to rise and fall, enabling the training roll 33 to unfold at different heights, thus achieving dynamic adjustment of the training position and meeting the training needs in different scenarios. Simultaneously, by setting a controller, the first drive mechanism 50, the second drive mechanism 60, and the third drive mechanism 70 can be coordinated to achieve automated and intelligent adjustment of the training roll 33, making operation simple and convenient, improving work efficiency and training effectiveness.

[0031] It should be noted that in this embodiment, the training frame 10 is a U-shaped frame structure, and the training space is the internal space of the U-shaped frame structure. The training board 20 can rotate relative to the training frame 10 under the action of the first driving mechanism 50, so that the training board 20 can be parallel to the training frame 10, that is, the training board 20 is in the training space; of course, it can also be at a certain angle to the training frame 10, that is, part of the training board 20 is in the training space, so as to adapt to the needs of observing the training roll 33 from different angles and in different scenarios.

[0032] Specifically, in this embodiment, the training frame 10 includes a base 11 and an outer frame 12. The outer frame 12 is connected to the base 11. The outer frame 12 has a C-shaped structure and a training space is formed between the outer frame 12 and the base 11.

[0033] It should be noted that in this embodiment, the controller is built into the base 11, which improves the overall compactness and aesthetics of the device and reduces exposed wiring. Of course, the controller buttons can also protrude from the outer surface of the base 11, making it convenient for operators to operate and control.

[0034] Please refer to Figure 4 , Figure 4 for Figure 3 A magnified view of a section at point A, combined with Figures 2-4 In order to facilitate the rotational coordination between the training board 20 and the training frame 10, a first rotating shaft 21 is provided on the side of the training board 20 near the base 11, and the first rotating shaft 21 is rotatably connected to the base 11.

[0035] Furthermore, in order to facilitate the installation of the first rotating shaft 21 and improve rotational stability, a rotating part 114 is provided on the side of the base 11 near the training board 20. The rotating part 114 has a rotating groove (not shown in the figure), and the first rotating shaft 21 is disposed in the rotating groove.

[0036] To further improve rotational stability, in this embodiment, a second rotating shaft 22 is provided on the side of the training board 20 away from the base 11, and the second rotating shaft 22 is rotatably connected to the outer frame 12.

[0037] Please continue to combine Figures 2-4 Specifically, the first drive mechanism 50 includes a first motor 51, a first detection switch (not shown), and a first transmission assembly 52. ​​The first motor 51 is mounted on the training frame 10, the first detection switch is mounted on the first motor 51, and the first transmission assembly 52 is connected to both the first motor 51 and the training board 20. The first motor 51 drives the training board 20 to rotate relative to the training frame 10 via the first transmission assembly 52. ​​The controller is electrically connected to both the first motor 51 and the first detection switch.

[0038] The controller can control the operation of the first motor 51 according to the preset rotation angle and speed. Specifically, the first detection switch can detect the rotation position and speed of the first motor 51 in real time and feed the information back to the controller. Based on the feedback information, the controller precisely adjusts the output of the first motor 51 and drives the training board 20 to rotate at multiple angles through the first transmission component 52, ensuring that the training board 20 accurately reaches the preset angle and rotates at a stable speed. If the training board 20 encounters an obstacle or other abnormal situation during rotation, the first detection switch will promptly transmit a signal to the controller, which will immediately stop the rotation of the first motor 51 and issue an alarm. After the abnormal situation is resolved, the operator can restart the rotation operation, thereby meeting the observation and operation needs in different training scenarios and greatly improving the flexibility, applicability, and safety of the device.

[0039] Specifically, the first transmission assembly 52 includes a driving wheel 521, a driven wheel 522, and a belt 523. The driving wheel 521 is connected to the output end of the first motor 51, and the driven wheel 522 is connected to the training board 20. The driving wheel 521 is connected to the driven wheel 522 via the belt 523. In this embodiment, the driven wheel 522 is connected to the first rotating shaft 21.

[0040] It should be noted that in other embodiments, the first transmission component 52 may also be other transmission components such as gear and rack transmission, sprocket and chain transmission.

[0041] Furthermore, in order to facilitate the installation of the first motor 51 and improve its working stability, in this embodiment, the first drive mechanism 50 also includes a first mounting bracket 53, which is disposed on the base 11 of the training frame 10, and the first motor 51 is disposed on the first mounting bracket 53.

[0042] Please refer to Figure 5 , Figure 5 for Figure 3A magnified view of a section at point B, combined with... Figure 3 and Figure 5 The second drive mechanism 60 includes a second motor 61, a second detection switch (not shown), and a second transmission assembly 62. The second motor 61 is mounted on the training plate 20, and its output end is connected to one end of the unwinding roller 31. The second detection switch is mounted on the second motor 61. The second transmission assembly 62 is connected to the other end of the unwinding roller 31 and to the take-up roller 32. The second motor 61 drives the unwinding roller 31 to rotate relative to the training plate 20, thereby driving the take-up roller 32 to rotate relative to the training plate 20 via the second transmission assembly 62. The controller is electrically connected to both the second motor 61 and the second detection switch.

[0043] During the exercise, the controller can control the rotation speed of the second motor 61 according to the preset unwinding and winding speed. Specifically, the second detection switch can monitor the actual rotation speed of the second motor 61 in real time and feed it back to the controller. The controller compares the actual rotation speed with the preset rotation speed. If there is a deviation, it automatically adjusts the input power of the second motor 61 to ensure that the exercise roll 33 is stably unwinded and wound at the preset speed. When the exercise needs to be paused or the unwinding and winding direction needs to be changed, the operator can send a command to the controller through the control switch. The controller responds quickly and adjusts the forward and reverse rotation and rotation speed of the second motor 61, thereby adjusting the rotation speed of the unwinding roller 31. This causes one end of the exercise roll 33 wrapped around its outer side to slowly unwind, while the winding roller 32 also slowly rotates to begin winding the exercise roll 33. The exercise roll 33 records in detail key information of the construction project cost budget, such as the details of various expenses and the cost change trends at different stages. This provides clear and continuous display content for the cost budget exercise, effectively improving the intuitiveness and accuracy of the exercise, greatly reducing the operational difficulty of the exercise device, and improving work efficiency.

[0044] Specifically, the second transmission assembly 62 includes a first gear 621 and a second gear 622. The first gear 621 is disposed at the end of the unwinding roller 31 away from the second motor 61, and the second gear 622 is disposed at the end of the take-up roller 32 away from the second motor 61, and the first gear 621 and the second gear 622 mesh.

[0045] In other words, under the driving action of the second motor 61, the unwinding roller 31 drives the upper first gear 621 to rotate synchronously. The first gear 621 and the unwinding roller 31 work together to transmit the rotational power through precise meshing with the second gear 622. Since the second gear 622 is fixedly connected to the take-up roller 32, the take-up roller 32 begins to rotate synchronously in the opposite direction to the unwinding roller 31. This reverse rotation design will enable the training roll 33 to be unwound at one end while the other end can be rolled up in an orderly manner, avoiding the accumulation and chaos of the roll, and further improving the stability and accuracy of the training roll 33 in the display process.

[0046] It should be noted that in other embodiments, the second transmission component 62 may also be other transmission components such as belt 523 pulley drive, sprocket and chain drive or gear and rack drive.

[0047] Furthermore, in order to facilitate the installation of the second motor 61 and improve its working stability, in this embodiment, the second drive mechanism 60 also includes a second mounting bracket 63, which is disposed on the training board 20, and the second motor 61 is disposed on the second mounting bracket 63.

[0048] Please continue to combine Figure 3 The roll take-up and unwind assembly 30 also includes a driven roller 34, an unwind roller 31 and a take-up roller 32, all located on one side of the training plate 20. The driven roller 34 is rotatably disposed on the opposite side of the training plate 20, and the training roll 33 abuts against the outer side of the driven roller 34.

[0049] As is easily understood, the driven roller 34 can cooperate with the unwinding roller 31 and the take-up roller 32 to assist in unwinding and taking up the rolled material. Specifically, the driven roller 34 not only supports the training rolled material 33, reducing friction between the training rolled material 33 and other components, but also makes fine adjustments during the transport of the training rolled material 33, ensuring that it always remains flat and stable. This provides a reliable way to display information for construction cost budgeting exercises, further improving the stability and accuracy of the training rolled material 33 during the display process.

[0050] Furthermore, to facilitate the installation of the unwinding roller 31 and the take-up roller 32, in this embodiment, the upper and lower ends of one side of the training plate 20 are respectively provided with a first protrusion 23 and a second protrusion 24. The two ends of the unwinding roller 31 and the take-up roller 32 are rotatably connected to the first protrusion 23 and the second protrusion 24, respectively. The first gear 621 and the second gear 622 are both provided on the side of the first protrusion 23 away from the second protrusion 24, and the second mounting bracket 63 is provided on the side of the second protrusion 24 away from the first protrusion 23.

[0051] Similarly, in order to facilitate the installation of the driven roller 34, in this embodiment, the upper and lower ends of the opposite side of the training plate 20 are respectively provided with a third protrusion 25 and a fourth protrusion 26, and the two ends of the driven roller 34 are rotatably connected to the third protrusion 25 and the fourth protrusion 26 respectively.

[0052] Please refer to Figure 6 , Figure 6 This is a first-view assembly diagram of the lifting assembly 40 and the third drive mechanism 70 provided in this embodiment, combined with... Figure 2 and Figure 6 Specifically, the lifting assembly 40 includes a support plate 41, a first rotating rod 42, and a second rotating rod 43. The support plate 41 is spaced apart from the training frame 10. The first rotating rod 42 and the second rotating rod 43 are rotatably connected. One end of the first rotating rod 42 is hinged to the training frame 10, and the other end of the first rotating rod 42 is slidably engaged with the support plate 41. One end of the second rotating rod 43 is slidably engaged with the training frame 10, and the other end of the second rotating rod 43 is hinged to the support plate 41. The third driving mechanism 70 is disposed on the support plate 41 and connected to the end of the first rotating rod 42 near the support plate 41.

[0053] like Figure 6 As shown, the rotational cooperation of the first rotating rod 42 and the second rotating rod 43 forms a scissor crossbar structure. The first rotating rod 42 is driven to slide relative to the support plate 41 by the third driving mechanism 70, thereby causing the second rotating rod 43 to slide relative to the training frame 10, realizing the lifting and lowering operation of the training frame 10, and thus adjusting the height of the training roll 33.

[0054] The third drive mechanism 70 includes a drive element 71 and a third detection switch (not shown in the figure). The output end of the drive element 71 is connected to the lifting assembly 40. Specifically, in this embodiment, the drive element 71 is connected to the end of the first rotating rod 42 near the support plate 41, and the third detection switch is disposed on the drive element 71. The controller is electrically connected to both the drive element 71 and the third detection switch.

[0055] It should be noted that in this embodiment, the driving component 71 is specifically a cylinder; of course, in other embodiments, the driving component 71 can also be a hydraulic cylinder or an electric push rod or other driving structures.

[0056] As is easily understood, the controller can control the drive component 71 according to a preset height value. For example, in this embodiment, the controller can control the extension and retraction of the cylinder. Specifically, a third detection switch installed on the cylinder is used to start and stop the cylinder's operation and monitor the cylinder's extension and retraction position in real time. The cylinder pushes the first rotating rod 42 to rotate relative to the second rotating rod 43, and the distance between the training frame 10 and the support plate 41 is adjusted by the sliding cooperation between the first rotating rod 42 and the second rotating rod 43 and the support plate 41, respectively. When the height approaches the preset value, the controller gradually reduces the driving force of the cylinder, allowing the device to smoothly reach the target height, further enhancing the device's practicality and convenience in different environments.

[0057] To improve stability during the lifting process, there are two first rotating rods 42 and two second rotating rods 43, with the two first rotating rods 42 spaced apart and the two second rotating rods 43 spaced apart; one first rotating rod 42 is rotatably connected to one second rotating rod 43, and the other first rotating rod 42 is rotatably connected to the other second rotating rod 43. The third drive mechanism 70 is simultaneously connected to the end of both first rotating rods 42 near the support plate 41.

[0058] It should be noted that in other embodiments, the number of the first rotating rod 42 and the second rotating rod 43 may also be one, three, or four, etc.

[0059] In this embodiment, in order to facilitate the simultaneous driving of the two first rotating rods 42, the third driving mechanism 70 also includes a pull rod 72. The two ends of the pull rod 72 are respectively connected to the ends of the two first rotating rods 42 near the support plate 41, and the output end of the driving member 71 is connected to the pull rod 72.

[0060] Optionally, the lifting assembly 40 also includes a side plate 45, which is disposed on the support plate 41. The fixed end of the drive component 71 is disposed on the side plate 45, which can improve the installation stability of the drive component 71.

[0061] Optionally, the lifting assembly 40 also includes fasteners 48, and the two ends of the pull rod 72 are connected to the two first rotating rods 42 through the fasteners 48, which can improve the connection stability between the two.

[0062] To further improve drive stability, the third drive mechanism 70 also includes a pull block 73, which is disposed on the pull rod 72, and the output end of the drive component 71 is connected to the pull block 73.

[0063] Furthermore, in order to improve the rotational stability between the two first rotating rods 42 and the two second rotating rods 43, so as to improve the smoothness of the height adjustment of the training frame 10, in this embodiment, the lifting assembly 40 also includes a connecting shaft 46. One end of the connecting shaft 46 is rotatably engaged with the connection between one of the first rotating rods 42 and one of the second rotating rods 43, and the other end of the connecting shaft 46 is rotatably engaged with the connection between the other first rotating rod 42 and the other second rotating rod 43.

[0064] Optionally, in order to further improve the connection strength between the two first rotating rods 42 and the two second rotating rods 43 and enhance the stability during the lifting process, in this embodiment, the lifting assembly 40 further includes a reinforcing rod 47, the two ends of which are respectively connected to the two second rotating rods 43.

[0065] Please continue to combine Figure 2 and Figure 6 To facilitate the overall installation of the training frame 10 and improve lifting stability, the lifting assembly 40 also includes a lifting plate 44. The lifting plate 44 is spaced apart from the support plate 41, and the training frame 10 is mounted on the lifting plate 44, located on the side of the lifting plate 44 away from the support plate 41. The end of the first rotating rod 42 away from the support plate 41 is hinged to the lifting plate 44, and the end of the second rotating rod 43 away from the support plate 41 is slidably engaged with the lifting plate 44.

[0066] Combination Figure 2 , Figure 4 and Figure 6 The base 11 includes a first fixing part 111, a connecting part 112, and a second fixing part 113 connected in sequence. The first fixing part 111 and the second fixing part 113 are spaced apart. The outer frame 12 is connected to both the first fixing part 111 and the second fixing part 113. The connecting part 112 is spaced apart from the lifting plate 44. Specifically, in this embodiment, the driving wheel 521, the driven wheel 522, and the belt 523 are all located on the side of the connecting part 112 closer to the lifting plate 44, while the rotating part 114 and the first mounting bracket 53 are all located on the side of the connecting part 112 away from the lifting plate 44. This ensures that the first rotating shaft, the first transmission component 52, and the first motor 51 do not interfere with each other during operation, thus improving the rotational stability of the training plate 20.

[0067] Please refer to Figure 7 and Figure 8 , Figure 7 This is a second-view assembly diagram of the lifting assembly 40 and the third drive mechanism 70 provided in this embodiment. Figure 8 for Figure 7 A magnified view of a section at point C. (Combined with...) Figures 6-8The support plate 41 is provided with a first slide rail 411, the lifting plate 44 is provided with a second slide rail 441, the first rotating rod 42 is provided with a first roller 421 at one end near the support plate 41, and the first roller 421 is slidably disposed on the first slide rail 411; the second rotating rod 43 is provided with a second roller 431 at one end near the lifting plate 44, and the second roller 431 is slidably disposed on the second slide rail 441.

[0068] In this embodiment, the smoothness and stability of the training frame 10 during the lifting and lowering process can be improved through the sliding cooperation between the slide rail and the roller. It should be noted that when the drive component 71 pushes the pull block 73 to move, the first roller 421 slides within the first slide rail 411. The controller can determine the height adjustment status of the training frame 10 by detecting the position of the first roller 421. When the height approaches the preset value, the controller gradually reduces the driving force of the drive component 71, allowing the device to smoothly reach the target height. After the height adjustment is completed, the controller controls the drive component 71 to lock, ensuring the device height is stable, thereby completing the overall lifting and lowering of the training frame 10.

[0069] Furthermore, to facilitate the installation and rotational engagement of the first rotating rod 42 and the second rotating rod 43 with the lifting plate 44 and the support plate 41 respectively, in this embodiment, the support plate 41 is further provided with a first rotating sleeve 412, and the lifting plate 44 is further provided with a second rotating sleeve 442. The end of the first rotating rod 42 near the lifting plate 44 is rotatably connected to the second rotating sleeve 442, and the end of the second rotating rod 43 near the support plate 41 is rotatably connected to the first rotating sleeve 412.

[0070] As described above, the controller can comprehensively coordinate the actions of the first motor 51, the second motor 61, and the drive component 71 according to different training scenarios and needs. Specifically, when it is necessary to simultaneously adjust the winding and unwinding speed of the training roll 33, the rotation angle of the training plate 20, and the height of the training frame 10, the controller will rationally allocate the action time and intensity of each component according to a preset logical sequence and priority to achieve the best training effect. At the same time, the controller will also monitor the working status of each component in real time, such as the current and temperature of the first motor 51 and the second motor 61, and the pressure of the drive component 71 (cylinder). When abnormalities occur, corresponding protective measures will be taken in a timely manner to ensure the safe and reliable operation of the training device.

[0071] In summary, embodiments of the present invention provide a construction project cost budgeting simulation device 100, which includes a simulation frame 10, a simulation board 20, a roll material unwinding assembly 30, a lifting assembly 40, a drive mechanism, and a controller. The simulation frame 10 has a simulation space inside, the simulation board 20 is rotatably mounted on the simulation frame 10 and located within the simulation space, and the lifting assembly 40 is connected to the simulation frame 10. The roll material unwinding assembly 30 includes an unwinding roller 31, a winding roller 32, and a simulation roll material 33. Both the unwinding roller 31 and the winding roller 32 are rotatably mounted on the simulation board 20. One end of the simulation roll material 33 is connected to the unwinding roller 31, and the other end of the simulation roll material 33 is connected to the winding roller 32. The drive mechanism includes a first drive mechanism 50, a second drive mechanism 60, and a third drive mechanism 70. The first drive mechanism 50 is connected to the training plate 20, the second drive mechanism 60 is connected to both the unwinding roller 31 and the take-up roller 32, and the third drive mechanism 70 is connected to the lifting assembly 40. The controller is electrically connected to the first drive mechanism 50, the second drive mechanism 60, and the third drive mechanism 70 to control them, thereby adjusting the rotation angle of the training plate 20, the unwinding and take-up speed of the training roll 33, and the height of the training frame 10.

[0072] The construction project cost budgeting simulation device 100, through a second drive mechanism 60, can drive the unwinding roller 31 and the rewinding roller 32 to rotate relative to the simulation board 20, thereby causing the simulation roll material 33 to clearly and continuously display the simulation content on the simulation board 20, improving the intuitiveness of operation. Furthermore, through a first drive mechanism 50, it can drive the simulation board 20 to rotate relative to the simulation frame 10, enabling the simulation roll material 33 to be displayed at different angles. And through a third drive mechanism 70, it can drive the simulation frame 10 to rise and fall, enabling the simulation roll material 33 to unfold at different heights, thus achieving dynamic adjustment of the simulation position to meet the simulation needs in different scenarios. Simultaneously, by setting up a controller, it can coordinate the control of the first drive mechanism 50, the second drive mechanism 60, and the third drive mechanism 70 to achieve automated and intelligent adjustment of the simulation roll material 33, making operation simple and convenient, improving work efficiency and simulation effect.
