Description

Technical Field

[0001] This utility model belongs to the field of settlement monitoring technology, specifically relating to a road settlement and deformation monitoring device. Background Technology

[0002] During the use of roads after completion, road settlement may occur due to factors such as ground movement, excessive extraction of groundwater, or construction defects. In severe cases, this may induce collapse and pose a great safety hazard to the highway. Therefore, it is necessary to use monitoring devices to monitor road settlement.

[0003] Existing methods for monitoring road settlement typically involve leveling. Leveling rods are periodically placed on measuring poles and benchmarks, and height measurements are taken using a level instrument. However, existing leveling rods are usually held and stabilized manually. Since the measuring poles in leveling methods extend above the road surface, placing the leveling rod on the pole significantly raises its center of gravity. As the center of gravity rises, the distance between the holding and support point and the center of gravity increases, requiring more manpower to stabilize the rod and maintain its verticality. This increases the difficulty of keeping the leveling rod vertical, which significantly affects the final monitoring data and can lead to more serious losses. In conclusion, manually holding the leveling rod makes it difficult to guarantee measurement accuracy. Utility Model Content

[0004] The present invention aims to provide a road settlement and deformation monitoring device to solve the problem mentioned above that it is difficult to ensure measurement accuracy by manually holding a leveling rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road settlement and deformation monitoring device, comprising... The settlement assembly includes a base plate, a measuring rod, and a sleeve. The measuring rod is installed on the base plate, and the sleeve is set on the base plate and fitted over the measuring rod. Clamping assembly, detachably mounted on the sleeve; The measuring assembly includes a stabilizing sleeve, an extension rod, a vertical plate, a limiting bolt, and a leveling rod. The vertical plate is installed on the clamping assembly, the extension rod is slidably inserted into the vertical plate, the stabilizing sleeve is fixed to one end of the extension rod and abuts against the top surface of the measuring rod, the leveling rod is slidably inserted into the stabilizing sleeve and the bottom surface of the leveling rod abuts against the top surface of the measuring rod, and the limiting bolt is threaded into the vertical plate and the end of the limiting bolt abuts against the extension rod.

[0006] The principle and effects of this technical solution: 1. By connecting the vertical plate to the clamping assembly, the position of the vertical plate relative to the measuring rod and the sleeve can be kept stable. The extension rod allows the position of the stabilizing sleeve relative to the top of the measuring rod to be adjusted. The stabilizing sleeve guides and limits the leveling rod, making it less likely to tip over while keeping it vertical.

[0007] 2. By sliding the extension rod and the vertical plate together, part of the overturning force on the stabilizing sleeve can be overcome by the vertical plate. At the same time, the limit bolt abuts against the extension rod, and the other part of the force along the length of the extension rod can also be overcome by the frictional force generated by the limit bolt. Since the overturning force of the leveling rod on the stabilizing sleeve is not consistent with the direction of movement of the extension rod or the length direction of the sleeve, the clamping assembly and the extension rod do not need excessive friction to maintain a stable position.

[0008] The present invention is further configured such that an observation port is provided on one side of the stabilizing sleeve.

[0009] The principle and effect of this technical solution: The setting of the observation port ensures that the fixing sleeve can fix the lower end of the leveling rod without obstructing the dimensions of the lower end of the leveling rod.

[0010] The present invention is further configured such that: the clamping assembly includes a V-shaped plate, a U-shaped plate, a clamping plate and a clamping screw, one end of the U-shaped plate is rotatably connected to the V-shaped plate, the other end of the U-shaped plate is detachably connected to the V-shaped plate, the clamping plate is slidably fitted to the inner side of the U-shaped plate, the clamping screw is threaded into the U-shaped plate, and the end of the clamping screw extends to be rotatably connected to the clamping plate, and the sleeve abuts against the clamping plate and the V-shaped plate respectively.

[0011] The principle and effect of this technical solution: By using the V-shaped plate and clamping plate to abut against the outer wall of the sleeve, a three-point clamping effect can be achieved. At the same time, the V-shaped plate has a centering effect when it abuts against the sleeve. By rotating the clamping screw, the position of the clamping plate inside the U-shaped plate can be controlled, that is, the position can be adjusted according to the size of the sleeve.

[0012] The present invention is further configured such that: the two sides of the clamping plate have sliders, and the side wall of the U-shaped plate is provided with a groove, and the sliders slide and engage in the groove.

[0013] The principle and effect of this technical solution: By sliding the slider in the groove, the rotation of the clamping plate can be restricted and it can be disengaged from the U-shaped plate, while the movement of the clamping plate can be guided.

[0014] The present invention is further configured such that: the clamping assembly also includes a connecting bolt, the end of which passes through the V-shaped plate and is threaded into the U-shaped plate.

[0015] The principle and effect of this technical solution: By threading the connecting bolts into the U-shaped plate, the connecting bolts can connect the U-shaped plate and the V-shaped plate into a whole, and can also be disconnected by rotation, so that the U-shaped plate and the V-shaped plate can be disassembled.

[0016] The present invention is further configured such that the length of the observation port is less than the length of the leveling rod.

[0017] The principle and effect of this technical solution: By controlling the length of the observation port, the leveling rod can be limited by the stabilizing sleeve, while the observation port will not obstruct the scale of the leveling rod, thus facilitating observation and use.

[0018] The present invention is further provided with rubber pads on the side walls of the V-shaped plate and the clamping plate.

[0019] The principle and effect of this technical solution: The rubber pad can increase the friction coefficient of the V-shaped plate and the clamping plate, thus fixing them more firmly to the outside of the sleeve. Furthermore, the rubber pad can be locally deformed by compression, thereby increasing the contact area between the V-shaped plate and the clamping plate and the sleeve. Attached Figure Description
