Description

Technical Field

[0001] The utility model relates to the technical field of highway design auxiliary equipment, and particularly relates to a subgrade design model based on highway design. Background Technique

[0002] The subgrade refers to a strip-shaped structure built as the pavement foundation according to the route position and certain technical requirements. It is the foundation of railways and highways and is a linear structure built with soil or stone materials. Traditional subgrade design models can usually simulate a proportionally reduced subgrade and obtain a series of chemical reaction data of the subgrade after experiencing different weather conditions, and then judge whether the subgrade can be used in the expected section according to the experimental data of the subgrade.

[0003] At present, the utility model patent with the publication number of CN219497235U discloses a subgrade design model based on highway design. This application can adjust the height of the model substrate according to different operating states, so that operators in different states can be at a relatively convenient operating height, improving the defect of poor operability of traditional highway design models.

[0004] In recent years, earthquakes have occurred frequently. Earthquakes may cause subgrade settlement, distortion and deformation, and cracks, bulges and wavy deformations may appear on the road surface. The above technical solutions cannot simulate the state of the subgrade under earthquake damage, resulting in researchers not being able to fully understand the design system of the subgrade. Content of the Utility Model

[0005] The purpose of the utility model is to provide a subgrade design model based on highway design to solve the problem that the state of the subgrade under earthquake damage cannot be simulated in the above background technique, resulting in researchers not being able to fully understand the design system of the subgrade.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A subgrade design model based on highway design, including a bottom plate and a model body. The top of the bottom plate is respectively provided with an earthquake simulation mechanism and a rain simulation mechanism.

[0007] The earthquake simulation mechanism includes a placement plate, a driving motor, a rotating shaft and a belt. A plurality of springs are fixedly connected between the bottom of the placement plate and the top of the bottom plate. Two convex blocks are fixedly sleeved on the outer wall of the rotating shaft. The two convex blocks are arranged in opposite directions on the outer wall of the rotating shaft. The number of the rotating shafts is two, and the two rotating shafts are symmetrically arranged about the model body in the front and back. One end of the rotating shaft located in the front of the model body is fixedly connected with the output end of the driving motor through a coupling. The other end of the rotating shaft is fixedly sleeved with a driving wheel, and the same end of the rotating shaft located in the back of the model body is fixedly connected with a driven wheel. The driving wheel and the driven wheel are connected by a belt transmission.

[0008] The present utility model is further configured as follows: The rainwater simulation mechanism includes a water tank and a water pump. A connecting pipe is communicatively arranged between the back surface of the water tank and the input end of the water pump. The output end of the water pump is communicatively connected with a delivery pipe, and the other end of the delivery pipe is communicatively connected with a nozzle.

[0009] With the above technical solution, powered by the water pump, the water in the water tank is transmitted to the nozzle through the connecting pipe and the delivery pipe, and then sprayed from the nozzle onto the model. In the study of the subgrade state under simulated rainfall conditions, it breaks through the limitation that traditional subgrade models cannot adapt to changing climate conditions, providing strong support for engineers to deeply master the subgrade design principle.

[0010] The present utility model is further configured as follows: A support leg is rotatably sleeved on the outer wall of the rotating shaft, and the support leg is fixedly connected to the top of the bottom plate.

[0011] With the above technical solution, the support leg is used to assist in supporting the rotating shaft. By being rotatably connected to the rotating shaft, it does not affect the rotation of the rotating shaft.

[0012] The present utility model is further configured as follows: The driving motor is fixedly connected to the outer wall of the support leg through a motor bracket.

[0013] With the above technical solution, the driving motor is the power source of the earthquake simulation mechanism, providing power for the mechanism.

[0014] The present utility model is further configured as follows: An L-shaped rod is fixedly connected to the top of the bottom plate, and the delivery pipe and the nozzle are fixedly connected to the outer wall of the L-shaped rod.

[0015] With the above technical solution, the L-shaped rod is used as a support auxiliary member, facilitating the support and fixation of the delivery pipe and the nozzle.

[0016] The present utility model is further configured as follows: The water tank and the water pump are both fixedly installed on the top of the bottom plate.

[0017] With the above technical solution, the water tank is used to provide water for the rainwater simulation mechanism, and the water pump serves as the power source to provide power for the water delivery.

[0018] The present utility model is further configured as follows: Continuous protrusions are provided at the four peripheral edges of the top of the bottom plate. A support seat is fixedly connected to the bottom of the bottom plate, and the model body is placed on the top of the placement plate.

[0019] With the above technical solution, by setting the four peripheral edges of the top of the bottom plate as continuous protrusions, the water sprayed by the rainwater simulation mechanism can be collected, preventing it from spreading everywhere and affecting the environment. The support seat provided at the bottom of the bottom plate makes the entire device have a certain height, facilitating use and observation.

[0020] The utility model provides a subgrade design model based on highway design, which has the following beneficial effects:

[0021] (1) The driving motor of the utility model drives the rotation of the rotating shaft on the front of the model body, thereby driving the rotation of the two oppositely arranged bumps fixedly sleeved on the outer wall of the rotating shaft. When the longer part of the bump rotates downward, it squeezes the placement plate downward. When it moves away from the lower part, the placement plate will move upward under the action of the spring, so that the state of the model body simulating the longitudinal seismic wave can be obtained during the up and down movement of the placement plate. And through the transmission of the driving wheel, the belt and the driven wheel, the rotating shaft on the back of the model body rotates, and then drives the two bumps on that rotating shaft to rotate. Through the rotation of the bumps on the two rotating shafts, the model body can be pushed back and forth to simulate the transverse seismic wave, so that the researchers can simulate the state of the subgrade under earthquake conditions, and then it is convenient for relevant personnel to fully understand the design system of the subgrade.

[0022] (2) The utility model provides power through a water pump, conveys the water in the water tank to the nozzle through the connecting pipe and the conveying pipe, and then sprays it onto the model by the nozzle to simulate the state of the subgrade in rainy weather, solving the problem that the subgrade model in the prior art cannot simulate the state in different weather conditions, and then it is convenient for relevant personnel to fully understand the design system of the subgrade.

There are two rotating shafts 24. , two rotating shafts 24 are symmetrically arranged front and back about the model body 4, the driving motor 23 is fixedly connected to the outer wall of the supporting leg 25 through a motor frame, the driving motor 23 is the power source of the earthquake simulation mechanism 2, and provides power for the mechanism, one end of the rotating shaft 24 located on the front of the model body 4 is fixedly connected to the output end of the driving motor 23 through a coupling, and a driving wheel 27 is fixedly sleeved on the outer wall of the other end of the rotating shaft 24, and a driven wheel 29 is fixedly connected to the outer wall of the same end of the rotating shaft 24 located on the back of the model body 4, and the driving wheel 27 and the driven wheel 29 are connected through a belt 28.

[0031] The rainwater simulation mechanism 3 includes a water tank 31 and a water pump 33. Both the water tank 31 and the water pump 33 are fixedly installed on the top of the bottom plate 1. The water tank 31 is used to supply water to the rainwater simulation mechanism 3, and the water pump 33 serves as a power source to provide power for the transportation of water.

And through the transmission of the driving wheel 27, the belt 28, and the driven wheel 29, the rotating shaft 24 on the back of the model body 4 rotates, and then drives the rotation of the two convex blocks 26 on that rotating shaft 24.
