Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a roadbed settlement detection device. Background Art

[0002] Roadbed settlement detection devices are equipment used to monitor and record roadbed settlement. They play an important role in the construction and operation of transportation infrastructure such as roads and railways. Settlement plates are one type of roadbed settlement detection device. After a highway is built using A4 soil as the cement subbase material, a roadbed settlement detection device is used to detect the roadbed settlement of the highway built with A4 soil as the cement subbase material in order to observe the degree of roadbed settlement.

[0003] However, the base plate and measuring rod of traditional roadbed settlement plates are often fixed together by threads or welding, which makes the disassembly and assembly of the base plate and measuring rod cumbersome and inconvenient, and thus makes it difficult to carry, store and use the roadbed settlement plate. Therefore, a roadbed settlement detection device is proposed to overcome the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a roadbed settlement detection device. By pulling the base plate to move the clamping plate, the clamping and fixing of the measuring rod is released. Then, by pressing the stop block, the stop block is released from the limiting block. Then, by rotating the measuring rod, the limiting block is rotated to release the limiting of the measuring rod, and the measuring rod can be removed from the protrusion. This solves the problem that the disassembly and assembly of the base plate and the measuring rod is cumbersome and inconvenient, which makes it difficult to carry, store and use the roadbed settlement plate.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a roadbed settlement detection device, including a base plate, a base plate, a protrusion, and a measuring rod. The top of the protrusion has an insertion hole, and the bottom end of the measuring rod is inserted into the insertion hole. The inner wall of the insertion hole has two vertical grooves, and the bottom of the two vertical grooves has mounting holes. The interior of the two mounting holes is provided with a second spring, and the top of the two second springs is connected to a stop block. A horizontal groove is provided on one side of each of the two vertical grooves. The outer wall of the measuring rod is provided with two limiting blocks, which are respectively set in the two horizontal grooves.

[0007] Furthermore, a mounting plate is provided on the top of the base plate, and a protrusion is installed at the top center of the mounting plate.

[0008] Furthermore, three grooves are evenly provided on the top of the mounting plate, and mounting rods are provided in the three grooves respectively. The outer walls of the three mounting rods are respectively fitted with first springs.

[0009] Furthermore, the substrate has three parts. A slider is provided on one side of the bottom end of the substrate. A sliding hole is provided on the slider. The slider is fitted onto the mounting rod through the sliding hole. One end of the first spring is connected to the slider and the other end is connected to one side of the sliding groove. A clamping plate is provided on the top side of one side of the substrate.

[0010] Furthermore, the substrate has a trapezoidal structure.

[0011] Furthermore, the clamp is located below the scale line on the measuring rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model moves the clamping plate by pulling the base plate, releasing the clamping and fixing of the measuring rod. Then, by pressing the stop block, the stop block compresses the second spring, causing the second spring and the stop block to retract into the mounting hole, thus releasing the stop block from limiting the limit block. Then, rotating the measuring rod causes the limit block to rotate, turning the limit block into the vertical groove, releasing the limit block from limiting the measuring rod, and the measuring rod can be removed from the protrusion. This solves the problem that the disassembly and assembly of the base plate and the measuring rod is cumbersome and inconvenient, which would make it difficult to carry, store and use the roadbed settlement plate.

[0014] 2. This utility model uses a clamping plate to hold and fix the measuring rod, and then the base plate can increase the stability of the measuring rod, enabling it to better detect the degree of settlement of the roadbed.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution: a roadbed settlement detection device, including a base plate 1, a base plate 3, a protrusion 4, and a measuring rod 5. The top of the protrusion 4 is provided with an insertion hole 401, and the bottom end of the measuring rod 5 is inserted into the insertion hole 401. The inner wall of the insertion hole 401 is provided with two vertical grooves 402, and the bottom of the two vertical grooves 402 is provided with mounting holes 404 respectively. The interior of the two mounting holes 404 is provided with second springs 405 respectively, and the top ends of the two second springs 405 are respectively connected to stop blocks 406, which are square structures. The side of the two vertical grooves 402 is provided with a horizontal groove 403 respectively, and the outer wall of the measuring rod 5 is provided with two limiting blocks 501, which are respectively disposed in the two horizontal grooves 403.

[0023] By pulling the base plate 3 to move the clamping plate 303, the clamping and fixing of the measuring rod 5 is released. Then, by pressing the stop block 406, the stop block 406 compresses the second spring 405, causing the second spring 405 and the stop block 406 to retract into the mounting hole 404, so that the stop block 406 releases the restriction on the limiting block 501. Then, by rotating the measuring rod 5, the limiting block 501 is rotated and rotated into the vertical groove 402, releasing the restriction on the measuring rod 5. The measuring rod 5 can then be removed from the protrusion 4. This solves the problem that the disassembly and assembly of the base plate 1 and the measuring rod 5 are cumbersome and inconvenient, which would make it difficult to carry, store and use the roadbed settlement plate.

[0024] The top of the base plate 1 is provided with a mounting plate 2, which is a circular structure. The protrusion 4 is installed in the middle of the top of the mounting plate 2. Three sliding grooves 201 are evenly opened on the top of the mounting plate 2. The three sliding grooves 201 are respectively provided with mounting rods 202. The mounting rods 202 are cylindrical structures. The outer walls of the three mounting rods 202 are respectively fitted with first springs 203.

[0025] The first spring 203 pushes the slider 301 to slide in the groove 201, thereby driving the base plate 3 and the clamping plate 303 to move, and then the clamping plate 303 fixes and limits the measuring rod 5.

[0026] There are three substrates 3. The substrates 3 are trapezoidal in structure. A slider 301 is provided on one side of the bottom end of the substrate 3. The slider 301 is square in structure and has a sliding hole 302. The slider 301 is fitted onto the mounting rod 202 through the sliding hole 302. One end of the first spring 203 is connected to the slider 301 and the other end is connected to one side of the sliding groove 201. A clamping plate 303 is provided on the top side of one side of the substrate 3. The clamping plate 303 is arc-shaped and is located below the scale line on the measuring rod 5.

[0027] The measuring rod 5 is clamped and fixed by the clamping plate 303, and the stability of the measuring rod 5 can be increased by the action of the base plate 3, so that it can better detect the degree of settlement of the roadbed.
