Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of simulation sand table for building engineering, and particularly relates to a simulation sand table for road and bridge engineering design. BACKGROUND

[0002] In road and bridge engineering design, simulation sand table is a very important tool, mainly used for intuitively showing and verifying design scheme, and assisting decision-making and optimization. The specific functions are as follows: simulation sand table can show the overall layout of road and bridge engineering in an intuitive and three-dimensional way, including road direction, bridge structure, surrounding topography and geomorphology, etc. Through physical or digital sand table, designers, decision-makers and stakeholders can more intuitively understand the design scheme. Through sand table model, actual terrain, bridge structure and road system can be simulated to verify the rationality of the design scheme. Problems in the design (such as space conflicts, unreasonable curve radii, etc.) can be found in advance and optimized and adjusted. Problems that may be encountered in the construction process, such as bridge erection, road excavation and filling, can be visualized to improve the feasibility of the construction scheme. Sand table model can also be used to demonstrate construction sequence, construction equipment arrangement, etc. Through sand table model, the relationship between the project and the surrounding environment can be simulated to evaluate the impact of the project on ecology, urban landscape and residents' life. Especially in mountainous areas with large elevation differences, sand table can help analyze the impact of the project on terrain transformation. Sand table is an important tool for communication with the public and stakeholders. Through visual models, it helps them understand the overall design of the project, increases transparency and reduces resistance.

[0003] The existing simulation sand table for road and bridge engineering design is basically fixed, but during the process of road and bridge engineering, local design may change, including changing the direction of the local area of the sand table for demonstration, especially in the function demonstration of the bridge, the existing sand table simulates the river through light, which reduces the authenticity of the simulation sand table and is not conducive to more specific function demonstration of the bridge.

[0004] In view of the above situation, in order to overcome the above technical problems, the utility model designs a portable metering equipment for road and bridge reconnaissance, which solves the above technical problems. UTILITY MODEL CONTENTS

[0006] In order to achieve the above technical purpose, the utility model provides the following technical scheme:

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1-8 As shown, a simulation sand table device for road and bridge engineering design includes a base mechanism 1, connecting components 2, an installation mechanism 3, and a sand table body 4. The base mechanism 1 is fixed to a display platform, providing a stable support foundation for the sand table. The connecting components 2 are located at the four corners of the base mechanism 1, mainly used for dynamic simulation of water flow and for support functions. The installation mechanism 3 is positioned above the base mechanism 1, used to support the sand table body 4 and adjust its position. The sand table body 4, located above the installation mechanism 3, is the core area for simulating road and bridge engineering design.

[0033] like Figure 6 As shown, the connecting component 2 has an ingenious structural design, comprising a connecting block 21, a connecting column 22, a water inlet channel 23, a water outlet channel 24, a support spring 25, and a telescopic ring 26. The connecting block 21 is fixed at the four corners of the base mechanism 1, providing basic support for the installation of the connecting column 22. The connecting column 22 is vertically positioned in the center of the connecting block 21, and has an inlet channel 23 inside to simulate water flow into the sandbox. An outlet channel 24 is located on the outer side of the top of the connecting column 22 for water to exit the sandbox. The support spring 25 is installed between the connecting column 22 and the connecting block 21, adjusting the stability and flexibility of the overall structure through elastic deformation. The telescopic ring 26 is located above the support spring 25, further enhancing the system's adaptability and ensuring that the connecting component 2 maintains good functionality under different load conditions.

[0034] The staff can adjust the position of the sand table body 4 by lifting the mounting mechanism 3, rotating to the appropriate position, and then putting down the mounting mechanism 3. When the mounting mechanism 3 and the base mechanism 1 are separated, the water flow path formed between the connecting assembly 2 and the mounting column 32 is also disconnected. During use, the base mechanism 1 can supply water to the mounting mechanism 3, which can simulate the characteristics of river and other water resources on the sand table, making it more realistic. On the other hand, it can also cool the sand table body. Since the sand table body now uses many electronic components and lamp tubes to simulate the actual road and bridge engineering status, it will generate heat and affect work efficiency and shorten the service life. Water cooling can effectively solve this problem.

[0035] As shown in Figures 3-4 , the base mechanism 1 includes a base body 11, a matching clamping block 12, a positioning assembly 13, and a support block 14. The base body 11 is fixedly installed on the display stand to provide overall load bearing and support functions. The matching clamping block 12 is installed on the inner side of the base body 11, which realizes stable connection with other components and prevents structural loosening. The positioning assembly 13 is arranged at the middle position of the base body 11 to ensure the accuracy of installation and stable positioning of components, thereby improving the safety of the device. The support blocks 14 are evenly distributed around the positioning assembly 13, which can effectively enhance the support performance of the structure, disperse pressure, and prolong the service life of the device. This design can ensure the structural stability and installation convenience of the base mechanism 1, and adapt to different usage scenarios.

[0036] As shown in Figure 4 , the upper surface of the support block 14 is designed as an inner concave conical surface. The concave conical surface can effectively concentrate the supporting force at the center point, making the force more uniform, thereby improving the stability and reliability of the support and reducing structural deformation or damage caused by uneven force. Enhance component fixation: The design of the conical surface can form a more stable contact with the bottom surface of the supported component, reducing the possibility of sliding or displacement through shape self-locking. The inner concave conical surface has a certain guiding function, which helps to automatically align the position of the component during installation, improving the accuracy and efficiency of installation.

[0037] As shown in Figure 5As shown, the positioning assembly 13 includes a steering block 131, a sliding groove 132, a telescopic sleeve 133 and a telescopic spring 134. Specifically, the steering block 131 is located at the upper part of the positioning assembly 13, which provides a rotating adjustment function to meet different angle requirements, enhancing the adaptability and flexibility of the assembly. The sliding groove 132 is opened in the inner side of the steering block 131 at the central axis position, which guides other components to slide along the predetermined path, ensuring the accuracy of positioning and reducing the deviation in operation. The telescopic sleeve 133 is arranged at the lower part of the positioning assembly 13, which provides support function for up and down movement to meet the requirements of height adjustment. The telescopic spring 134 is installed inside the telescopic sleeve 133, which provides buffering and return function through elastic restoring force, effectively preventing the influence of vibration on the structure, improving the stability and durability of the assembly. This structural design not only realizes flexible positioning in multiple directions, but also guarantees the overall installation stability and operation reliability.

[0038] As shown in Figure 7 The installation mechanism 3 includes an installation plate 31, an installation column 32, a clamping plate 33, a matching groove 34, a connecting block 35 and a rotating block 36, and each component has compact structure and clear function. Specifically, the installation plate 31 is fixedly installed above the base mechanism 1, serving as the core bearing component of the entire installation mechanism 3, providing a stable support surface. The installation column 32 is located at the lower bottom surface of the installation plate 31 at the four corners, which disperses the support force to ensure the stability and uniform stress of the installation plate 31, suitable for different load requirements. The clamping plate 33 is arranged below the installation plate 31, which is designed to realize clamping connection with other components, facilitating quick assembly and disassembly operation. The matching groove 34 is ingeniously opened on the four side surfaces of the clamping plate 33, which is used in cooperation with external components to further enhance the firmness and reliability of the connection. The connecting block 35 is fixedly installed at the lower middle position of the installation plate 31, serving as the hub of the installation mechanism 3, and cooperates with the rotating block 36 to realize flexible angle adjustment function. The rotating block 36 is distributed around the connecting block 35, which meets different direction adjustment requirements through precise rotating design, making the entire installation mechanism 3 have higher flexibility and adaptability. This design not only has reasonable structure, but also has good stability and easy operation.

[0039] As shown in Figure 8 The installation column 32 is a hollow structure, which is arranged as a hollow structure to pass water flow. The cross-sectional shape of the installation column 32 is arranged as a symmetrical L shape, which can ensure the rapid passage of water flow.

[0040] As shown in Figure 7 The side surface of the rotating block 36 is provided with a plurality of freely rotating rolling balls, which rotate in the sliding groove 132 to reduce the friction force during rotation and ensure rapid rotation.

[0041] The bottom surface shape of the mounting column 32 and the shape of the telescopic ring 26 are set to be the same.

[0042] In the preliminary installation process, the user aligns the rotating block 36 with the positioning assembly 13, and after each matching groove 34 and matching block 12 are matched with each other, the user presses down to complete the installation, so that the rotating block 36 is clamped in the rotating block 36, the supporting block 14 and the connecting block 35 are matched with each other, the effect of point support is achieved, and the uniformity of the force of the base mechanism 1 is ensured.

[0043] An external water source is arranged below the base mechanism 1, the water source pumps water into the water inlet channel 23, and the water is in a sealed state due to the interception of the telescopic ring 26, and when the mounting mechanism 3 and the base mechanism 1 are combined, the mounting column 32 extrudes the telescopic ring 26 to overcome the elastic force of the supporting spring 25 and moves downward, and the water flow can enter the mounting column 32 from the water inlet channel 23 and the water outlet channel 24, thereby entering the inside of the mounting mechanism 3, and is used for cooling electronic components and simulating river and other geomorphic features.

[0044] When the direction of the sand table body 4 needs to be adjusted, the mounting mechanism 3 is lifted, the telescopic sleeve 133 moves upward, the required angle is rotated, and then the mounting mechanism 3 is lowered, at this time, the supporting block 14 and the connecting block 35 are in contact again, and the support is ensured.
