Description

Technical Field

[0001] This invention belongs to the field of model testing technology, specifically relating to a safe observation and operation platform and operation method for a physical simulation test device. Background Technology

[0002] During model testing, observation from various angles and operation from appropriate positions are crucial for the smooth progress of the experiment. Model testing systems are generally large in size, and numerous limitations and safety hazards exist around the device during operation. Operators cannot easily grasp the experimental progress and perform corresponding operations, and relevant personnel cannot observe from different angles, hindering their understanding and mastery of the experiment. Therefore, a visitable operating platform accompanying the simulation testing system is essential.

[0003] However, in current model testing, operators, in pursuit of convenience, often fail to properly design and maintain the supporting operating platform, which can easily lead to accidents and poses significant safety hazards. As people's requirements for safe laboratory operations increase, it is essential to ensure that the operating platform is safe, reliable, provides a good view, is aesthetically pleasing, and easy to use.

[0004] Currently, there is no design for a corresponding visitor operation platform in the field of physical simulation experiments, while there are already various construction operation platforms in the construction field.

[0005] For example, Chinese patent CN 201921131181.6 invented a construction operation ladder, which is composed of multiple standard sections. It is easy to disassemble, assemble, and recycle, avoiding the need to frequently set up temporary operation ladders during construction, thus saving labor and time. It is equipped with braked steering wheels and adjustable support legs, making it easy to move without compromising safety, and is highly practical.

[0006] Chinese patent CN111058611A invented a method for constructing high-altitude steel structures and a self-climbing operating platform for construction. The device consists of two platforms, an upper platform and a lower platform. The upper platform does not require large external machinery and can be lifted by two hand-operated hoists, which facilitates the lifting operation.

[0007] Chinese patent CN202210437054.9 discloses a tilting device for welding hydraulic supports with adjustable angle. The tilting platform is provided with operating platforms on both sides, the axis of the operating platform is parallel to the axis of the tilting platform, and the upper surface of the operating platform is lower than the upper surface of the tilting platform. The operating platform is provided with guardrails and ladders on both sides to facilitate manual operation and observation of the weld.

[0008] Chinese patent CN 114572864 A discloses an omnidirectional mobile platform, an intelligent stacking crane, and its control method and system. This omnidirectional mobile platform features a triangular chassis, a stable center of gravity, and efficient use of storage space, offering advantages such as small size, high space utilization, and high flexibility. In terms of control, the flexible application of optical tracking provides accurate positioning and flexible movement. However, the platform's robotic arm can only be used for grasping goods, which cannot meet the requirements for experimental model fabrication.

[0009] Existing operating platforms primarily consider practical requirements such as minimizing floor space required during construction and flexible mobility, but their main limitations are as follows:

[0010] (1) Poor compatibility of the operating platform. The existing operating platforms are mainly used in engineering construction and are mostly simply built according to construction requirements. They are not compatible with the functions of physical simulation test benches and cannot meet the operation requirements of model tests; the overall coordination is poor.

[0011] (2) The degree of mechanization is low. The operating platform can only provide a certain operating space for the operator and cannot cooperate with the operator to carry out automated operation. Summary of the Invention

[0022] The lower end of the three-dimensional moving frame is equipped with a model-making robotic arm, which can realize multi-degree-of-freedom motion of rotation and extension, thereby realizing the production of complex geological structure models.

[0023] Furthermore, the test platform includes a main frame and an automatic sliding loading top beam disposed on the main frame. A flipping track is rotatably connected to the automatic sliding loading top beam. A first driving part is disposed on the automatic sliding loading top beam.

[0028] The secondary platform has multiple maintenance windows arranged in an array at one end near the test platform;

[0029] A plurality of visiting platform support columns are circumferentially arranged at the lower end of the secondary visiting platform. A wire mesh fence is arranged between two adjacent visiting platform support columns to prevent personnel from moving under the top beam. Among them, a safety passage is arranged on the wire mesh fence on the opposite side of the primary operation platform to facilitate the maintenance or transportation of test instruments.

[0030] A gantry crane is arranged on the secondary visiting platform to assist the operator in installing and transporting test instruments.

[0031] Furthermore, it further includes an operating pedal. The operating pedal includes a bottom plate, a folding pedal hinged to the bottom plate, and a support oil cylinder for driving the folding pedal to rotate relative to the bottom plate. The bottom plate is fixedly installed on the primary operation platform. One end of the support oil cylinder is hinged to the primary operation platform, and the other end is hinged to the folding pedal.

[0032] Folding guardrails and extension guardrails are arranged on both sides of the folding pedal. The extension guardrail is connected to one side of the folding guardrail at an adjustable angle, and the other side of the folding guardrail is installed on the primary operation platform at an adjustable angle.

[0033] Furthermore, a model making module connecting the primary operation platform and the secondary visiting platform is arranged on the top of the test platform. The model making module includes a crane and a multi-degree-of-freedom robotic arm. Among them, the crane is used to assist the operator in transporting the materials required for model making.
