Description

Technical Field

[0001] The present invention relates to the technical field of road engineering, and in particular to a settlement observation device used in road engineering. Background Art

[0002] Road engineering refers to the entire process of planning, design, construction, maintenance, and management of roads, as well as the physical construction involved. Subsidence observation in road engineering is crucial in many ways. Uneven road settlement can lead to cracks, potholes, and other road surface defects. For example, if settlement is significant on one side of a road, longitudinal cracks may form, allowing rainwater to seep into the roadbed through these cracks, further destabilizing it and shortening the road's service life. Subsidence observation can help identify abnormal settlements promptly, allowing appropriate repair measures to prevent further damage.

[0003] When observing road settlement, a base plate is usually buried in the road, and then the road settlement problem is observed based on the displacement of the observation rod. In some areas with complex geological conditions or low foundation bearing capacity, the base plate of the settlement plate may shift due to disturbance of the foundation soil or its own gravity, resulting in inaccurate monitoring data. Therefore, a settlement observation device for road engineering is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that in areas with complex geological conditions or low foundation bearing capacity, the bottom plate of the settlement plate may shift due to disturbance of the foundation soil or its own gravity, resulting in inaccurate monitoring data. A settlement observation device for road engineering is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The cam is secured to the upper edge of the base plate and secured to the lower edge of the base plate by a secure connection between the cam and the lower edge of the base plate. The second transmission unit drives multiple extension plates to move to the outside of the base plate. The larger contact area can disperse the load borne by the base plate and reduce the pressure per unit area, thereby reducing the risk of the base plate settling or shifting due to excessive local pressure, and improving the stability of the base plate on the road. At the same time, the first movable plate is lifted and forms a forty-five-degree angle with the extension plate. When the first rotating rod rotates, the second movable plate is driven downward through the third transmission unit, and at the same time, multiple fixed rods are driven to insert into the soil. The larger contact area can disperse the load borne by the base plate and reduce the pressure per unit area, thereby reducing the risk of the base plate settling or shifting due to excessive local pressure, and improving the stability of the base plate on the road.

[0007] The above technical solution further includes:

When the observation rod rotates and drives the circular plate to move downward, the movable rod is extended and retracted in the circular ring by the spring to adapt to the up and down movement of the circular plate.

[0009] A fixing groove is provided on the upper part of the circular plate, and a fixing block is installed at the bottom of the observation rod. The size of the fixing groove opening is adapted to the size of the fixing block. After the fixing block is inserted into the fixing groove, when the observation rod is rotated to connect with the fixing ring, the circular plate can be driven to rotate through the fixing block.

[0012] A plurality of moving rods are slidingly provided on the inner side of the sliding groove, the first threaded rod is threadedly connected to the moving rod, and the end of the moving rod away from the circular plate is fixedly connected to the extension plate. When the first rotating rod rotates, the first threaded rod is driven to rotate through the first bevel gear and the second bevel gear. When the first threaded rod rotates, it drives the moving rod and the extension plate to move toward the outside of the sliding groove.

[0013] A second square groove is provided on the inner side of the extension plate, and a torsion spring is installed on one end of the second rotating rod extending to the inner side of the second square groove. The torsion spring is fixedly connected to the inner wall of the second square groove. The torsion spring in the contracted state is reset, and at the same time, the first movable plate is lifted up by the second rotating rod and forms an angle of forty-five degrees with the extension plate.

[0015] The plurality of fixing rods are evenly distributed horizontally on the second movable plate.

[0016] The size of the opening of the opening slot is adapted to the size of the second movable plate, and the size of the opening of the sliding slot is adapted to the size of the extension plate.

[0017] The present invention has the following beneficial effects:

[0018] In the present invention, by arranging a stabilizing component, when the observation rod is installed on the base plate, multiple extension plates can increase the contact area between the base plate and the road.

When the first rotating rod 5 rotates, the third transmission unit drives the second movable plate 21 to move downward, and at the same time drives the multiple fixed rods 22 to insert into the soil. The larger contact area can disperse the load borne by the base plate and reduce the pressure per unit area, thereby reducing the risk of the base plate settling or shifting due to excessive local pressure, and improving the stability of the base plate on the road.

The torsion spring 19 in the contracted state is reset, and at the same time, the first movable plate 17 is lifted up by the second rotating rod 16 and forms an angle of forty-five degrees with the extension plate 25.

[0036] The third transmission unit includes a sliding block 20 installed on the upper part of the second movable plate 21, and the sliding block 20 is slidably connected to the base plate 1. A second threaded rod 23 is installed at the bottom of the first rotating rod 5, and the second threaded rod 23 is threadedly connected to the sliding block 20. An open groove 26 is provided at the bottom of the base plate 1, and the second movable plate 21 is slidably arranged on the inner side of the open groove 26. The force generated when the second threaded rod 23 rotates drives the sliding block 20 and the fixed rod 22 to move downward.

When the observation rod 3 is rotated and connected to the fixing ring 2, the circular plate 9 can be driven to rotate by the fixing block 4. When the circular plate 9 rotates, the first rotating rod 5 can be driven to rotate by the movable rod 8 and the circular ring 6. When the observation rod 3 rotates and drives the circular plate 9 to move downward, the movable rod 8 is retracted and expanded in the circular ring 6 by the spring 7 to adapt to the up and down movement of the circular plate 9. When the first rotating rod 5 rotates, it can drive the first bevel gear 11 to rotate. Since the first bevel gear 11 is meshed with the second bevel gear 27, the first rotating rod 5 drives the first threaded rod 13 to rotate through the first bevel gear 11 and the second bevel gear 27 when the first rotating rod 5 rotates. The force generated when the first threaded rod 13 rotates drives the movable rod 14 to move toward the outside of the sliding groove 12, and at the same time drives the extension plate 25 to move, so that the extension plate 25 moves to the outside of the sliding groove 12, increasing the connection between the bottom plate 1 and the road The contact area of ​​the road is larger, and the larger contact area can disperse the load borne by the base plate, reduce the pressure per unit area, thereby reducing the risk of settlement or displacement of the base plate due to excessive local pressure, and improving the stability of the base plate on the road. At the same time, when the extension plate 25 moves to the outside of the sliding groove 12, the torsion spring 19 in the contracted state is reset, and at the same time, the first movable plate 17 is lifted up by the second rotating rod 16 and forms a forty-five degree angle with the extension plate 25, and when the first rotating rod 5 rotates, it can drive the second threaded rod 23 to rotate. The force generated by the rotation of the second threaded rod 23 drives the sliding block 20 to move downward, and at the same time drives the second movable plate 21 to move downward along the open groove 26, and at the same time drives the fixing rod 22 to move downward, so that the fixing rod 22 is inserted into the soil, reducing the lateral movement of the base plate 1. After the fixing rod 22 is inserted into the soil and the first movable plate 17 is lifted, it provides an additional lateral constraint for the base plate 1, which can effectively resist the external force of the base plate in the horizontal direction, reduce the lateral movement of the base plate, and ensure the accuracy of the base plate position during settlement observation.
