Existing technologies offer limited simulation mechanisms for rapid erection systems for large, heavy-duty cylinders. While some simulation tools exist, most rely on simplified models or localized simulations, lacking the ability to accurately simulate and optimize the entire erection process. Furthermore, existing simulation mechanisms exhibit slow response speeds, often exceeding the second level, and occupy a significant amount of space, making it difficult to meet the demands for high precision and rapid response.

By adjusting the mechanism size and excitation, the simulation mechanism system can achieve the target "angle-time" curve for large, heavy-loaded cylinders, simulating the sub-second cylinder erection process.

[0028] like Figure 3As shown, the scissor assembly 100 is the main component for realizing the functions of the large-scale heavy-loaded cylinder rapid erection simulation mechanism system. The scissor assembly 100 includes a connecting plate 101, a thrust bearing 102, a scissor arm 103, a needle bearing 104, a scissor arm fixing seat 105, a support base 106, a limit block 107, a guide rail 108, a slider 109, and a scissor arm slider fixing seat 110. The connecting plate 101 connects the scissor assembly 100 to the cylindrical equivalent component 500. The support base 106 is a stable support platform and fixed platform for the large-scale heavy-loaded cylinder rapid erection simulation mechanism system and is fixedly connected to the ground. There are four scissor arms 103, and two of them form a group of cross-shaped scissor arms 103 to form a scissor mechanism. There are two thrust bearings 102, and the two thrust bearings 102 are respectively installed between the two scissor arms 103 of the two groups of scissor mechanisms to reduce friction when the scissor arms 103 rotate relative to each other. The two groups of scissor mechanisms are installed side by side and in parallel between the connecting plate 101 and the supporting base 106. The two groups of scissor mechanisms are installed on the supporting base 106 along the horizontal axis of the supporting base 106 as the center of symmetry, thereby ensuring the stability of the movement process. The number of the scissor arm fixing seats 105 is four, and the connecting plate (101) and the supporting base (106) are fixedly connected to the fixed end of the scissor arm (103) through the scissor arm fixing seat (105). Specifically, the scissor arm fixing seat 105, the guide rail 108, and the limit block 107 are all connected to the connecting plate 101 and the supporting base 106 by bolts. The connecting plate 101 and the supporting base 106 are connected to the free end of the scissor arm 103 by the scissor arm slider fixing seat 110, the slider 109, the guide rail 108 and the limit block 107 in a sliding manner. There are two guide rails 108 on the support base 106. The two guide rails 108 are arranged side by side and in parallel on the upper surface of the support base 106 with the horizontal axis of the support base 106 as the center of symmetry. There are two guide rails 108 on the connecting plate 101. The two guide rails 108 are arranged side by side and in parallel on the lower surface of the connecting plate 101 with the horizontal axis of the connecting plate 101 as the center of symmetry. A plurality of limit blocks 107 are fixed on both sides of the guide rails 108 to prevent the sliders 109 from falling out of the guide rails 108, thus playing a safety role. There are four sliders 109. The four sliders 109 are respectively installed in the guide rails 108 on the connecting plate 101 and the support base 106. There are four scissor arm slider fixing seats 110. The sliders 109 are fixedly connected to the scissor arm slider fixing seats 110 and locked with bolts. The guide rails 108 and the sliders 109 form a linear pair. The free end of the scissor arm 103 is linearly moved, and the scissor mechanism has a degree of freedom of 1 and a defined motion trajectory. The motion trajectories of the two scissor mechanisms are symmetrical, ensuring stability during the erection process.The scissor arm 103 and the scissor arm fixing seat 105 , as well as the scissor arm 103 and the scissor arm slider fixing seat 110 are connected by hinged bolts, and the friction is reduced by a needle bearing 104 .

[0029] like Figure 4 As shown, the drive assembly 200 includes a high-pressure cylinder 201, a cylinder fixing bracket 202, a Y-shaped adapter 203, a fisheye joint 204, a tension sensor 205, an H-shaped adapter 206 and a tension transmission rod 207. The high-pressure cylinder 201 provides adjustable tension for the drive assembly and is fixed to the support base 106 through the cylinder fixing bracket 202. The piston of the high-pressure cylinder 201 is connected to the Y-shaped adapter 203 by means of a thread. The two ends of the tension sensor 205 are respectively connected to the fisheye joint 204, and then one end is connected to the Y-shaped adapter 203 and the other end is connected to the H-shaped adapter 206. The function of the fisheye joint 204 is to adjust the tension angle and eliminate the remaining lateral forces. The tension sensor 205 is used to monitor the thrust of the high-pressure cylinder in real time. The other end of the H-shaped adapter 206 is connected to the tension transmission rod 207. The other end of the tension transmission rod 207 is divided into two ends and is respectively connected to the two scissor arm slider fixing seats 110. The tension transmission rod 207 uniformly transmits the tension generated by the high-pressure cylinder 201 to the scissor arm slider fixing seat 110. The Y-shaped adapter 203 and the fisheye joint 204, the fisheye joint 204 and the H-shaped adapter 206, the H-shaped adapter 206 and the tension transmission rod 207, and the tension transmission rod 207 and the scissor arm slider fixing seat 110 are connected by pins to ensure uniformity of tension transmission.

[0030] like Figure 5As shown, the buffer assembly 300 includes a housing 301, a buffer spring 302, a buffer seat 303, a linear bearing 304, and a buffer rod 305. The housing 301 is fixedly connected to the support base 106. Specifically, the housing 301 is fixedly connected to the support base 106 by bolts to transmit the buffer force to the support base 106. The buffer spring 302 is placed in the inner hole of the housing 301 to absorb part of the kinetic energy of the large-scale heavy-loaded cylindrical rapid erection system simulation mechanism and reduce the internal impact of the large-scale heavy-loaded cylindrical rapid erection system simulation mechanism. Preferably, the stiffness of the buffer spring 302 is adjustable to meet the impact absorption requirements of different loads. The linear bearing 304 is installed at the opening of the inner hole of the housing 301. The buffer rod 305 and the linear bearing 304 form a linear motion pair. The buffer seat 303 is fixedly connected to the buffer rod 305. Specifically, the buffer seat 303 and the buffer rod 305 are connected by the external thread of the buffer seat 303 and the internal thread of the buffer rod 305. When the buffer rod 305 is acted upon by the tension transmission rod 207, the buffer seat 303 contacts and compresses the buffer spring 302, thereby reducing the impact. There are two buffer assemblies 300, which are mounted side by side and parallel to the support base 106 along the horizontal axis of the support base 106, enhancing the buffering effect.

[0031] like Figure 6 As shown, since the scissor arms 103 of the scissor assembly 100 overlap in the initial state and there is a dead point in movement, the spring assembly 400 is designed to open the adjacent scissor arms 103 to a certain angle to help the scissor assembly 100 pass the dead point. The spring assembly 400 includes a spring rod 401, a spring spring 402, and a spring seat 403. One end of the spring spring 402 is placed in a blind hole inside the spring rod 401, and the other end is in contact with the support base 106. The spring rod 401 is in contact with the cylindrical equivalent assembly 500. The spring seat 403 and the spring rod 401 form a set of cylindrical pairs. Preferably, the spring seat 403 and the spring rod 401 are both designed with convex rings to play a guiding and limiting role and prevent the spring rod 401 from detaching. Before the large-size heavy-load cylinder rapid erection simulation mechanism system is released, the spring spring 402 is in a maximum compression state. When released, the adjacent scissor arms are opened to a certain angle.

[0032] like Figure 7As shown, the cylinder equivalent component 500 is a simplified large-sized heavy-duty cylinder, and a part of the cylinder is used to equivalent the actual cylinder. The cylinder equivalent component 500 includes a cantilever 501, a connecting seat 502, an equivalent cylinder 503 and a releaser 504. One end of the cantilever 501 is fixedly connected to the connecting plate 101, and the other end is connected to the equivalent cylinder 503 through the connecting seat 502; the releaser 504 provides an interface for the locking of the system, supporting manual release and automatic release. Preferably, the size and weight of the equivalent cylinder 503 are replaceable and can be adjusted according to actual needs to adapt to the erection simulation of cylinders of different sizes and weights.

[0033] The scissor assembly achieves rapid erection simulation of a large, heavy-duty cylindrical equivalent assembly through the coordination of its scissor arms with the guide rails and sliders, and the tension applied by the drive assembly to the scissor arm slider mount via a tension transfer rod. The scissor-type design enables equivalent single-axis rotation of a large, heavy-duty cylinder, reducing the space occupied by the mechanism and enabling the entire simulation process to be completed in sub-second time, achieving a sub-second response. The present invention incorporates a scissor assembly, a drive assembly, a buffer assembly, a spring assembly, and a cylindrical equivalent assembly to accurately simulate the structure and composition of the erection process of a large, heavy-duty cylinder. Furthermore, an adjustable load solution is provided for simulating the erection process of cylinders of varying weights and sizes. The protection simulation mechanism can adjust the load according to actual needs to verify its adaptability to different cylinder types. The present invention provides a design solution that improves the response speed of the simulation process, enabling the simulation mechanism to accurately and real-timely reflect the dynamic process of heavy-duty cylindrical erection. This technology ensures the system's rapid response to complex environments and changing conditions. Simulate the rapid erection of large, heavy-loaded cylinders in confined spaces, achieving efficient simulation of the erection process of large, heavy-loaded cylinders in limited spaces.
