Description

Technical Field

[0001] This application relates to the field of roadbed testing technology, and more specifically, to a device for measuring highway foundation settlement. Background Technology

[0002] When constructing a highway, a foundation must be laid first, followed by the pouring of cement or asphalt on the surface. As the highway is subjected to loads, the foundation soil will undergo vertical deformation or settlement due to compression, resulting in an uneven highway. Therefore, it is necessary to regularly inspect the highway to determine the degree of settlement and repair it in a timely manner.

[0003] Existing technology publication CN219218615U discloses a highway settlement depth detection device, including a foundation component, a pavement detection mechanism, other components, and a roadbed detection mechanism. The roadbed detection mechanism is characterized in that: the roadbed detection mechanism is located inside the foundation component, the other components are located at the top of the roadbed detection mechanism, and the pavement detection mechanism is located at the top of the other components; the pavement detection mechanism includes a fixed plate, a transverse support rod is fixedly connected to the left end of the fixed plate, and a longitudinal connecting rod is fixedly connected to the bottom left side of the transverse support rod. In this invention, the measurement markers are fixed by installing pre-embedded foundation components. During highway surveying, the level of the measurement markers can be measured, using them as temporary reference points, making surveying more convenient during highway construction. This achieves the effect of multiple uses for the device and plays a multi-functional role.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks:

[0005] The detection point is located at a fixed point on the shoulder of the road, which means that the foundation settlement can only be detected at a certain point on the road, and it is not possible to quickly detect and display the overall foundation settlement of the road.

[0006] Regarding the aforementioned related technologies, the inventor believes that the detection point is fixed at the shoulder, thus it can only detect the foundation settlement at a certain point of the highway, and cannot quickly detect and display the overall foundation settlement of the highway.

[0007] In view of this, we propose a device for measuring highway foundation settlement. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this application is to provide a device for measuring highway foundation settlement, which solves the technical problem in the above-mentioned background technology that the detection point is fixed at the shoulder, thus only the foundation settlement of a certain part of the highway can be detected, and the overall foundation settlement of the highway cannot be quickly detected and displayed, thereby achieving the technical effect.

[0010] 2. Technical Solution

[0011] This application provides a device for measuring highway foundation settlement, comprising:

[0012] Mounting plate;

[0013] The mounting plate has sliding rods that slide through both sides, and the side wall of the mounting plate is threaded with locking bolts.

[0014] Fixed plates are fixedly installed at both ends of the slide rod;

[0015] Wheels are installed on the bottom of the fixing plate;

[0016] Mounting posts, the mounting plate is provided with two mounting posts;

[0017] A roll of drawing paper is fitted onto the mounting post;

[0018] A testing mechanism is mounted on the mounting plate.

[0019] A transmission mechanism is installed between the mounting plate and the wheel, and the transmission mechanism is connected to the mounting column.

[0020] With the above method, the wheels move along the road shoulder, thereby driving the paper roll to rotate through the transmission mechanism. At the same time, the detection mechanism moves along the road surface, thereby drawing up and down fluctuations on the paper roll, which intuitively reflects the road settlement.

[0021] Optionally, a handle is installed on the side wall of the mounting plate, a locking nut is installed on the top of the mounting column, one mounting column is fixedly connected to the mounting plate, and the other mounting column rotates through the mounting plate, and an anti-slip rubber ring is fixedly provided on the surface of the rotating mounting column.

[0022] Optionally, the transmission mechanism includes a fixed base, a fixed base is fixedly installed on the bottom of the mounting plate, a rotating tube is rotatably sleeved on the fixed base, a bevel gear meshing with the rotating tube and a mounting post penetrating the mounting plate is sleeved on the rotating tube, a transmission shaft is rotatably sleeved between the fixed plates at both ends of one of the slide rods, and wheels are fixedly connected to both ends of the transmission shaft, the transmission shaft passes through the rotating tube, a spline is fixedly provided on the transmission shaft, and a keyway for engaging the spline is opened on the inner wall of the rotating tube.

[0023] With the above solution, the drive shaft and rotating tube are kept rotating synchronously when the mounting plate is adjusted, through the snap-fit ​​of splines and keyways. When the wheel rotates, the drive shaft drives the rotating tube to rotate, and the rotating tube drives the mounting column to rotate through bevel gears, so as to achieve the purpose of rotating the paper roll to pull the paper.

[0024] Optionally, the detection mechanism includes lifting rods, multiple lifting rods are slidably sleeved on the mounting plate, each lifting rod has a U-shaped seat fixedly installed at its bottom, a roller is installed inside the U-shaped seat, a spring is sleeved on the lifting rod between the top of the U-shaped seat and the bottom of the mounting plate, a fixing ring is fixedly installed at the top of the lifting rod, and a paintbrush is sleeved inside the fixing ring.

[0025] The above method uses a spring to make the roller conform to the road surface. When the wheel moves, the roller moves along the road. When it encounters a settlement area, the roller will move down, so that the paintbrush can draw a curve on the paper that reflects the undulation of the road surface, which can intuitively show the settlement of the roadbed.

[0026] Optionally, an adhesive plate is fixedly installed on the mounting plate, the paper of the paper roll is adhered to the adhesive plate, the lengths of the multiple lifting rods increase sequentially, and a baseline is provided on the paper of the paper roll.

[0027] Using the above method, the height of the baseline is the same as the height of the pen when the bottom of each roller is aligned with the bottom of the wheel. Thus, when the curve drawn by the pen at the settlement point is compared with the baseline, the settlement depth and distance can be reflected.

[0028] 3. Beneficial effects

[0030] 1. This application uses a wheel that moves along the road shoulder. When the wheel rotates, the drive shaft drives the rotating tube to rotate.

[0036] Reference Figure 1 This application provides a device for measuring highway foundation settlement, comprising: a mounting plate 1; a sliding rod 2, with sliding rods slidably passing through both sides of the mounting plate 1, and locking bolts threaded onto the side wall of the mounting plate 1; a fixing plate 3, with fixing plates 3 fixedly installed at both ends of the sliding rod 2; wheels 4, with wheels 4 installed at the bottom of the fixing plates 3; mounting posts 5, with two mounting posts 5 on the mounting plate 1; a drawing roll 6, with a drawing roll 6 sleeved on the mounting posts 5; a detection mechanism 7, with a detection mechanism 7 installed on the mounting plate 1; and a transmission mechanism 8, with a transmission mechanism 8 installed between the mounting plate 1 and the wheels 4, and the transmission mechanism 8 connected to the mounting posts 5. The wheels 4 move along the road shoulder, thereby driving the drawing roll 6 to rotate through the transmission mechanism 8. At the same time, the detection mechanism 7 moves along the road surface, thereby drawing up and down fluctuations on the drawing roll 6, visually reflecting the highway settlement.

[0037] Reference Figure 1 A handle is installed on the side wall of the mounting plate 1, and a locking nut is installed on the top of the mounting column 5. One mounting column 5 is fixedly connected to the mounting plate 1, and the other mounting column 5 rotates through the mounting plate 1. The surface of the rotating mounting column 5 is fixedly provided with an anti-slip rubber ring. The handle facilitates the movement of the device. The rotating mounting column 5 clamps the drawing paper roll 6 through the anti-slip rubber ring, thereby causing the drawing paper roll 6 to rotate and achieve the purpose of moving the drawing paper.

[0038] Reference Figure 1 and Figure 3The transmission mechanism 8 includes a fixed base 81. The fixed base 81 is fixedly installed on the bottom of the mounting plate 1. A rotating tube 82 is rotatably sleeved on the fixed base 81. A bevel gear 83 meshes with the rotating tube 82 and the mounting post 5 that passes through the mounting plate 1. A transmission shaft 84 is rotatably sleeved between the fixed plates 3 at both ends of a slide rod 2. The two ends of the transmission shaft 84 are fixedly connected to wheels 4. The transmission shaft 84 passes through the rotating tube 82. A spline 85 is fixedly provided on the transmission shaft 84. A keyway is opened on the inner wall of the rotating tube 82 to engage the spline 85. Through the engagement of the spline 85 and the keyway, the transmission shaft 84 and the rotating tube 82 are always kept rotating synchronously when the mounting plate 1 is adjusted. When the wheel 4 rotates, the transmission shaft 84 drives the rotating tube 82 to rotate. The rotating tube 82 drives the mounting post 5 to rotate through the bevel gear 83, so as to achieve the purpose of rotating the paper roll 6 to pull the paper.

[0039] Reference Figure 1 and Figure 2 The detection mechanism 7 includes a lifting rod 71. Multiple lifting rods 71 ​​are slidably sleeved on the mounting plate 1. A U-shaped seat 72 is fixedly installed at the bottom of each lifting rod 71. A roller 73 is installed inside the U-shaped seat 72. A spring 74 is sleeved on the lifting rod 71 between the top of the U-shaped seat 72 and the bottom of the mounting plate 1. A fixing ring 75 is fixedly installed at the top of the lifting rod 71. A paintbrush 76 is sleeved inside the fixing ring 75. The spring 74 makes the roller 73 fit against the road surface. When the wheel 4 moves, the roller 73 moves along the road. When it encounters a settlement area, the roller 73 will move down, so that the paintbrush 76 draws a curve with the undulation of the road surface on the drawing paper, which intuitively reflects the settlement of the roadbed.

[0040] Reference Figure 1 and Figure 3 A bonding plate 9 is fixedly installed on the mounting plate 1. The paper of the drawing paper roll 6 is bonded to the bonding plate 9. The lengths of multiple lifting rods 71 ​​increase sequentially. A baseline is provided on the drawing paper of the drawing paper roll 6. The height of the baseline is the height of the pen 76 when the bottom of each roller 73 is aligned with the bottom of the wheel 4. Thus, when the curve drawn by the pen 76 at the sinking point is compared with the baseline, the sinking depth and distance can be reflected.

[0041] Working principle: The wheel 4 moves along the shoulder. When the wheel 4 rotates, the drive shaft 84 drives the rotating tube 82 to rotate. The rotating tube 82 drives the mounting column 5 to rotate through the bevel gear 83, so that the drawing paper roll 6 rotates to pull the drawing paper. The spring 74 makes the roller 73 fit in contact with the road surface. When the wheel 4 moves, the roller 73 moves along the road. When it encounters a settlement, the roller 73 will move down, so that the pen 76 draws a curve with the undulation of the road surface on the drawing paper, which intuitively reflects the settlement of the roadbed and achieves long-distance detection of the road with clear results.
