Description

Technical Field

[0001] This invention relates to the field of model testing technology, specifically to a system and method for intelligent laying and waste recycling of large-scale physical simulation test models. Background Technology

[0002] In the research of underground engineering, theoretical research often assumes idealized conditions and simplifies numerical simulation parameters. However, field research is difficult, costly, and prone to errors, leading to distorted and unintuitive results. Physical simulation experiments, with their advantage of being able to repeatedly simulate the entire process of construction disaster evolution under multiple conditions, working conditions, and factors, have become an indispensable and important means for discovering new phenomena, exploring new laws, revealing new mechanisms, and verifying new theories in deep engineering.

[0003] Physical simulation testing is a method of scaling down engineering problems based on the principle of similarity. Through a certain similarity scale conversion, model tests can reflect the relationship between geological structure and engineering structure, more accurately simulate the construction process and its impact, and provide more intuitive test results, making it easier to analyze the stress distribution, deformation law, and stability characteristics of rock mass engineering. However, the mechanical parameters of the original rock are quite complex, and after proportional reduction, they cannot be simulated by a single material. Therefore, preparing similar materials suitable for specific stratum parameters and constructing similar models reasonably are necessary conditions for accurate model test research. Traditional model experiments rely on manual or semi-manual material preparation and laying, which has the following main drawbacks:

[0004] (1) Large error: The model test uses a lot of materials. The preparation and laying of similar materials need to be carried out in batches and cycles. Under artificial conditions, the parameters (compaction strength, laying route, etc.) of each cycle cannot be accurately controlled, which easily causes errors in the parameters of each layer of materials.

[0005] (2) Low efficiency: The production of geological similarity models has a low level of intelligence and mainly relies on manual labor, which is time-consuming and labor-intensive.

[0006] (3) High pollution: The raw materials of similar materials are mostly powder particles, which will generate a lot of dust pollution during the preparation and laying process, seriously affecting the hygiene of the laboratory environment.

[0007] Based on the above problems, the existing automated similar model production systems mainly include the following types:

[0008] Chinese patent CN201921131181.6 discloses a similarity simulation experimental system and method based on 3D printing rapid prototyping technology. This invention applies 3D rapid prototyping technology to the material preparation and spreading experiments of mining physical similarity simulation models, enabling the spreading of complex geological rock mass models such as folds, faults, and collapse columns that cannot be spread using traditional methods. However, this system suffers from drawbacks: viscous similar materials can clog the conveying pipes during material feeding, and uneven spreading can occur due to dead corners during model making. Furthermore, it lacks a compaction module, resulting in poor similarity model forming quality.

[0009] Chinese patent CN201911064657.3 discloses a 3D printing system for complex large-scale structural models. Through the simultaneous collaboration of structural printing components and a robotic arm assembly, it can achieve high-quality, high-efficiency, and high-precision machining of complex large-scale structural models. However, this system cannot automatically weigh and mix similar materials, lacks a compaction module, and the forming effect of similar models is uncontrollable.

[0010] The doctoral dissertation from Northeastern University, titled "Research and Application of 3D Printing Technology for Three-Dimensional Physical Models of Rock Mass," developed a large-scale 3D physical model printing device. This device was used to 3D print various engineering and geological structure physical models, such as tunnels and faults, and to evaluate the model forming accuracy and mechanical properties. However, the system can only produce paste-like models and lacks a compaction mechanism, making it impossible to control the material density.

[0011] Existing automated production systems for similar models each have their own characteristics, but their main limitations are as follows:

[0012] (1) The lack of a systematic intelligent material delivery module and concept makes it impossible to reasonably control the powder scattering and flying during the preparation and transportation of similar materials.

[0013] (2) Existing printing modules are mainly suitable for concrete materials, which solidify quickly and have uncontrollable strength. They do not meet the similarity criteria and are not suitable for printing similar materials with low moisture content and poor fluidity.

[0014] (3) Existing 3D printing modules for similar simulation tests do not have vibration compaction devices, which cannot control the strength and density of materials, affecting the model forming effect; and cannot achieve accurate reproduction of complex geology;

[0015] (4) It does not have a waste recycling module, making waste disposal difficult after the experiment, resulting in serious material waste and also harming the laboratory environment. Summary of the Invention

[0035] The dynamic load mechanism includes a vibration motor and a vibration spring. The vibration motor is fixedly mounted on a lower pressure plate at its bottom. The lower pressure plate and the upper pressure plate are connected by a guide post. The bottom of the guide post is fixedly mounted on the lower pressure plate, and the top of the guide post passes through a bolt hole in the upper pressure plate. The vibration spring is sleeved on the outside of the guide post.

[0036] Furthermore, a tilting cylinder is arranged on one side of the static load cylinder, and a telescopic guide rod is arranged on the other side. One end of the tilting cylinder and the telescopic guide rod are both hinged to the connecting plate, and the other end is both hinged to the upper pressure plate.

[0040] The tunneling cutterheads are distributed around the dust extraction channel on the cutterhead;

[0041] A drive motor is disposed on the top of the cutterhead and connected to the tunneling cutter head;

[0042] A waste conveying subsystem is used to convey the generated waste through the dust extraction channel to a designated recycling area.

[0043] The method for using a large-scale physical simulation test model intelligent laying and waste recycling system includes the following steps:

[0044] S1. Based on the volume of the experimental model, determine the similar materials required for each layer and calculate the weight required for each material;

[0045] S2. Open the switch valve at the bottom of the hopper, and the material falls into the automatic weighing device.

Detailed Implementation

[0066] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0067] Example 1

[0068] structure Figures 1 to 7 This embodiment provides a large-scale physical simulation test model intelligent laying and waste recycling system, including: model platform 3, automatic batching, mixing and conveying subsystem 1, 3D intelligent construction laying subsystem 2, and waste recycling subsystem 5;

[0069] The automatic batching, mixing and conveying subsystem 1 is located on one side of the model platform 3. The automatic batching, mixing and conveying subsystem 1 includes dry material mixing devices 1-4, which are used to mix similar materials.

[0070] The 3D intelligent construction laying subsystem 2 is set on the top of the model platform 3. The 3D intelligent construction laying subsystem 2 includes a wet material mixing device 2-4. The wet material mixing device 2-4 is connected to the dry material mixing device 1-4 through a first vacuum feeder 2-2. The wet material mixing device 2-4 is used to mix similar materials and water.

[0071] The waste recycling subsystem 5 is located at the bottom of the 3D intelligent construction laying subsystem 2 and is used to cut and crush the model and suck out the generated waste materials.

[0072] During operation, similar materials are mixed using a two-stage mixing method: dry material mixing and wet material mixing. First, the dry materials are mixed evenly in a dry powder mixer, and then conveyed to a wet material mixing device where water and additives are added and mixed. This reduces the time and distance that wet materials are transported in pipelines, making it suitable for similar materials with low moisture content and poor flowability.

[0073] Preferably, the automatic batching, mixing and conveying subsystem 1 further includes a dust-free feeding station 1-5 and a silo. The dust-free feeding station 1-5 is located on the ground on one side of the model platform 3. The inlet of the silo is connected to the dust-free feeding station 1-5 through a second vacuum feeder 1-1, and the outlet of the silo is connected to the dry material mixing device 1-4 through a third vacuum feeder.

[0074] In this embodiment, the silos are divided into large silos 1-2 and small silos 1-3, which can store similar materials according to their demand. The silos are also equipped with dust removal facilities to prevent dust from flying when materials are dropped.

[0075] In this embodiment, the silo is equipped with a metering sensor inside, a switch valve is provided at the outlet of the silo, and an automatic weighing device 1-6 is provided at the bottom of the outlet of the silo.

[0076] During operation, similar raw materials are sequentially fed into the dust-free feeding station 1-5. The dust-free feeding station 1-5 generates a certain negative pressure to remove dust emitted during material feeding, preventing dust leakage and achieving dust-free feeding of similar materials. The materials are then drawn into silos by the second vacuum feeder 1-1. Each silo has a valve at the bottom that automatically opens during weighing, allowing the material to enter the automatic weighing device 1-6 to weigh the required amount. This device can simultaneously measure and proportion multiple materials. Furthermore, the metering sensors designed in the silos can monitor the remaining material in each silo in real time. The quantity is convenient for test management; for similar materials with strong adhesion, in order to avoid clogging the pipeline during the transportation of similar materials, the weighed similar materials are stirred and mixed in the dry material mixing device 1-4, and then transported to the wet material mixing device 2-4 through the top first vacuum feeder 2-2. A predetermined amount of water and additives are added and stirring is continued to complete the preparation of similar materials; thus solving the problem that the existing technology lacks a systematic intelligent material delivery module and concept, and cannot reasonably control the powder scattering and flying during the preparation and transportation of similar materials.

[0077] Preferably, the 3D intelligent construction and laying subsystem 2 further includes: a main frame, a three-dimensional moving guide rail, a bidirectional sliding plate 2-7, and a material discharge pipe 2-5;

[0078] The main frame includes two horizontal beams 2-6 and one vertical beam 2-1. The vertical beam 2-1 is positioned between the two horizontal beams 2-6. The two horizontal beams 2-6 are arranged parallel to each other on the slide rail support 2-12 at the top of the model platform 3. The three-dimensional moving guide rail includes an X-axis rail 2-9, a Y-axis rail 2-10, and a Z-axis rail 2-3. The X-axis rail 2-9 is fixedly mounted on the top of the slide rail support 2-12, the Y-axis rail 2-10 is fixedly mounted on the inner wall of the horizontal beams 2-6, and the Z-axis rail 2-3 is fixedly mounted on the top of the slide rail support 2-12. The vertical beam 2-1 is placed on the outer wall of the vertical beam 2-1; the bidirectional sliding plate 2-7 is slidably mounted on the Y-axis track 2-10 on one side and on the Z-axis track 2-3 on the other side; the two horizontal beams 2-6 are slidably connected to the slide rail bracket 2-12 through the X-axis track 2-9; the feeding pipe 2-5 is located inside the vertical beam 2-1, the feeding end of the feeding pipe 2-5 is connected to the wet material mixing device 2-4 located on the upper part of the vertical beam 2-1, and the discharging end of the feeding pipe 2-5 extends into the model platform 3.

[0079] In this embodiment, the crossbeam 2-6 can be moved along the x-axis guide rail 2-9 by a motor to achieve material laying in the x-direction. The vertical beam 2-1 is connected to the crossbeam 2-6 by a track and a bidirectional sliding plate 2-7. The vertical beam 2-1 can be moved relative to the crossbeam 2-6 in the y-direction and z-direction by a motor.

[0080] The middle of the vertical beam 2-1 is a rib structure, and the top rib is used to fix the wet material mixing device 2-4. The rib is a hollow structure with a feeding pipe 2-5 inside, which transports the prepared similar material to the test bench 3.

[0081] Preferably, during the model laying stage, the bottom of the vertical beam 2-1 is connected to the dynamic and static composite loading and compaction mechanism 4 via a rotating mechanism 2-11; during the model material recycling stage, the bottom of the vertical beam 2-1 is connected to the waste recycling subsystem 5.

[0082] In this embodiment, the dynamic-static composite loading and compaction mechanism 4 includes a static load mechanism and a dynamic load mechanism. The static load mechanism includes a static load cylinder 4-2. One end of the static load cylinder 4-2 is connected to the rotating mechanism 2-11 through a connecting plate, and the other end is connected to the support of the upper pressure plate 4-7 through a ball joint 4-3. The dynamic load mechanism includes a vibration motor 4-5 and a vibration spring 4-4. The vibration motor 4-5 is fixedly mounted on the lower pressure plate 4-8 at its bottom. The lower pressure plate 4-8 and the upper pressure plate 4-7 are connected by a guide post. The bottom of the guide post is fixedly mounted on the lower pressure plate 4-8, and the top of the guide post passes through the bolt hole of the upper pressure plate 4-7. The vibration spring 4-4 ​​is sleeved on the outside of the guide post.

[0083] During operation, the rotary motor 2-8 drives the rotary mechanism 2-11, which in turn rotates the dynamic-static composite loading and compaction mechanism 4. The static load mechanism is connected to the hydraulic loading system and can apply a predetermined static thrust. The top of the static load cylinder 4-2 is connected to the support of the upper pressure plate 4-7 via a ball joint 4-3, which enables the inclined transmission of static load. The dynamic load mechanism can output a vibration load at a predetermined frequency. The lower pressure plate 4-8 is arranged at the bottom of the upper pressure plate 4-7, and the two are connected by a guide post. The guide post passes through the bolt holes of the upper pressure plate 4-7 and is movable relative to the upper pressure plate 4-7 to adapt to the deformation requirements of different materials. The vibration spring 4-4 ​​is sleeved on the guide rod, which can transmit the static load from the upper pressure plate 4-7 and also make the lower pressure plate 4-8 vibrate within a certain range under the drive of the vibration motor 4-5. The static load mechanism and the dynamic load mechanism work together to output a combined dynamic and static load to compact similar materials, making the strength and density of the similar materials more uniform. By adjusting the dynamic and static load strengths, the laying requirements of similar materials with different strengths can be met. This solves the problem that existing 3D printing modules for similar simulation experiments do not have a vibration compaction device, making it impossible to control the strength and density of materials, affecting the model forming effect, and failing to accurately reproduce complex geological conditions.

[0084] In this embodiment, a tilting cylinder 4-1 is arranged on one side of the static load cylinder 4-2, and a telescopic guide rod 4-9 is arranged on the other side. One end of both the tilting cylinder 4-1 and the telescopic guide rod 4-9 is hinged to the connecting plate, and the other end is hinged to the upper pressure plate 4-7. The top of the tilting cylinder 4-1 is connected to the rotating mechanism 2-11 through a support and a pin, and the bottom is connected to the upper pressure plate 4-7 through a support and a pin. During the test, the telescopic guide rod 4-9 can be moved by controlling the extension and retraction of the tilting cylinder, thereby tilting the upper and lower pressure plates at a specified angle. This can achieve the flattening of similar materials and meet the requirements for automated laying of inclined coal and rock layers. The tilting cylinder 4-1 and the rotating mechanism 2-11 can cooperate to realize the automated laying of coal and rock models with different inclination directions.

[0085] In this embodiment, the waste recycling subsystem 5 includes: a cutterhead 5-2, a dust extraction channel 5-3, a tunneling cutter head 5-4, a drive motor 5-1, and a waste conveying subsystem 6. The cutterhead 5-2 is connected to the bottom of the vertical beam 2-1; the dust extraction channel 5-3 is located in the middle of the cutterhead 5-2, and the tunneling cutter heads 5-4 are distributed around the dust extraction channel 5-3 on the cutterhead 5-2; the drive motor 5-1 is located at the top of the cutterhead 5-2 and connected to the tunneling cutter heads 5-4; the waste conveying subsystem 6 is used to convey the generated waste through the dust extraction channel 5-3 to a designated recycling area 7.

[0086] In this embodiment, the blades of the tunneling cutter head 5-4 are made of a combination of high-strength cemented carbide blades and diamond blades, resulting in strong rock-breaking ability and high efficiency. Each cutter head 5-4 is driven by a separate drive motor 5-1, which is mounted on the cutter head surface and rotates the cutter head. A tapered funnel-shaped dust collection channel is provided in the middle of the cutter head, and a vacuum pump is installed at the end of the channel to generate negative pressure inside the channel, reducing dust. When the cutter head 5-4 cuts the model, the waste material generated is extracted through the dust collection channel 5-3 and discharged to the designated recycling area 7 in the laboratory via the waste conveying system 6. This solves the problems of existing technologies that lack a waste recycling module, making waste disposal difficult after the experiment, resulting in serious material waste and negatively impacting laboratory hygiene.

[0090] S2. Open the switch valve at the bottom of the hopper, and the material falls into the automatic weighing device. When the predetermined weight is reached, the switch valve of the hopper is closed, and the weighed raw material is transported to the dry material mixing device 1-4 through the third vacuum feeder for primary mixing.

[0091] S3. The mixed dry material is conveyed to the wet material mixing device 2-4 through the first vacuum feeder 2-2, and a predetermined weight of water is added for secondary mixing to complete the preparation of similar materials.

[0092] S4. The prepared similar materials are transported into the model platform 3 through the feeding pipe 2-5. At the same time, the 3D intelligent construction and laying system moves in the X and Y directions to lay the materials evenly.

[0093] S5. The material is compacted by the dynamic and static composite loading compaction mechanism 4 and the main frame. The compaction density can be controlled by adjusting the output of the static load cylinder 4-2 and the amplitude of the vibration motor 4-5.

[0095] S7. After the test, replace the dynamic and static composite loading compactor with the waste recycling subsystem 5, crush the material and suck it away through the dust suction channel 5-3 to complete the recycling of similar materials.

[0096] Using the above-mentioned system and method, this invention completes the dust-free conveying of similar materials, the accurate reconstruction of similar physical models, and the green recycling of waste materials through an automatic batching, mixing and conveying subsystem, a 3D intelligent construction and laying subsystem, and a waste recycling subsystem, respectively. The whole system has a high degree of automation, and the preparation of similar materials and the production of test models are completed automatically without human intervention, which improves the efficiency of model testing and enhances test safety.

[0097] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention.
