Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a roadbed settlement detection device for municipal highways. Background Technology

[0002] With the continuous development of society and economy and the ongoing construction of modern cities, various municipal roads are constantly being built. The roadbed is a crucial foundation for road construction; once the roadbed settles, it can lead to problems such as cracking and subsidence of the road surface, ultimately damaging the road and affecting driving safety. Therefore, roadbed settlement monitoring is a necessary inspection item for municipal roads.

[0003] To accurately detect roadbed settlement, existing patent CN221882533U discloses a highway settlement detection device that can be easily supported inside settlement pits for adjustment and detection, facilitating precise alignment, adaptability, and stability. However, roadbed settlement can cause unevenness in the surrounding area. If the detection device in the aforementioned patent is placed in an uneven area, it will tilt, thus affecting the detection accuracy. Summary of the Invention

[0004] In view of this, the present invention discloses a roadbed settlement detection device for municipal highways, the purpose of which is to solve the problem that when the existing detection device is placed in an uneven area, it will cause the detection device to tilt, thereby affecting the detection accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roadbed settlement detection device for municipal highways includes a base with a spherical cavity. A connecting ball is disposed within the spherical cavity, and a support column is disposed on the connecting ball. Several support rods are hinged to the periphery of the support column. Each support rod has a support sleeve slidably connected to its end on the same axis. The ends of the support sleeves are all hinged to the base. A locking screw that abuts against the support rod is detachably connected to the support sleeve. A mounting seat is rotatably disposed on the support column, and a locking pin for limiting its rotation is detachably connected to the mounting seat. A support plate is disposed on the side wall of the mounting seat, and a detection structure for detecting settlement is disposed at the end of the support plate.

[0007] In this design, after placing the device on the ground, rotate the locking screw to remove it from contact with the support rod, allowing the support rod to slide relative to the support sleeve. At this point, the angle of the support column can be adjusted freely using the connection between the connecting ball and the base. Once the support column remains vertical, rotate the locking screw in the opposite direction to lock the support rod, thus securing the support column. This design avoids errors caused by device tilting, ensuring accurate detection of roadbed settlement. Furthermore, removing the locking pin allows rotation of the mounting base, which in turn rotates the detection structure, increasing the device's detection range.

[0008] Furthermore, the support plate is rotatably connected to a vertically arranged rotating shaft, and a pin that abuts against the rotating shaft is detachably connected to the support plate; the detection structure includes a horizontally arranged mounting plate, both ends of which are provided with vertically extending grooves that penetrate the mounting plate, and a sliding seat is slidably arranged in each groove. A positioning pin that abuts against the mounting plate is detachably connected to the sliding seat, and a detection rod is vertically slidably arranged on each sliding seat. A limiting pin that abuts against the detection rod is detachably connected to the sliding seat, and the middle part of the mounting plate is fixedly connected to the bottom of the rotating shaft.

[0009] In this scheme, by rotating the mounting base, the detection structure is positioned above the roadbed area to be detected. The positioning pin is removed, and the two sliding blocks are slid so that one detection rod is located at the edge of the roadbed settlement area, and the other detection rod is located within the roadbed settlement area. Then, the limiting pin is removed, allowing the detection rods to fall until they are in contact with the ground. The settlement height of the roadbed is measured by the height difference between the two detection rods. In addition, in this scheme, by sliding the two sliding blocks, both detection rods can be located at the edge of the detection area. The range of the settlement area is measured by the distance between the two sliding blocks, enabling the device to detect roadbed settlement data more comprehensively.

[0010] Furthermore, a level is provided on the support plate.

[0011] Furthermore, the detection rod has scale lines on its side wall, and the mounting plate also has scale lines on its upper surface.

[0012] Furthermore, a counterweight is provided on the mounting base.

[0013] Furthermore, a handle is provided at the top of the support column.

[0014] Furthermore, a rubber pad layer is provided at the end of the detection rod.

[0015] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0020] like Figures 1-2 As shown:

[0021] A roadbed settlement detection device for municipal highways includes a base 1 with a spherical cavity. A connecting ball 2 is disposed within the spherical cavity, and a support column 3 is disposed on the connecting ball 2. Several support rods 4 are hinged to the periphery of the support column 3. Each end of the support rod 4 is slidably connected to a support sleeve 5, and each end of the support sleeve 5 is hinged to the base 1. A locking screw 6 that abuts against the support rod 4 is detachably connected to the support sleeve 5. A mounting seat 7 is rotatably disposed on the support column 3, and a locking pin 8 for limiting its rotation is detachably connected to the mounting seat 7. A support plate 9 is disposed on the side wall of the mounting seat 7, and a detection structure for detecting settlement is disposed at the end of the support plate 9.

[0022] In this design, after placing the device on the ground, rotate the locking screw 6 to prevent it from contacting the support rod 4, allowing the support rod 4 to slide relative to the support sleeve 5. At this point, the angle of the support column 3 can be adjusted freely using the connection ball 2 and the base 1. After ensuring the support column 3 remains vertical, rotate the locking screw 6 in the opposite direction to lock the support rod 4, thus fixing the support column 3. This design avoids errors caused by device tilting in the detection structure, ensuring accurate detection of roadbed settlement. Furthermore, after removing the locking pin 8, the mounting base 7 can be rotated, thereby rotating the detection structure and increasing the detection range of the device.

[0023] In this embodiment, the support plate 9 is rotatably connected to a vertically arranged rotating shaft 10, and a pin 11 that abuts against the rotating shaft 10 is detachably connected to the support plate 9; the detection structure includes a horizontally arranged mounting plate 12, and both ends of the mounting plate 12 are provided with sliding grooves that pass through the mounting plate 12 vertically along its axial direction. A sliding seat 13 is slidably arranged in each of the sliding grooves, and a positioning pin 14 that abuts against the mounting plate 12 is detachably connected to the sliding seat 13. A detection rod 19 is slidably arranged vertically on each sliding seat 13, and a limiting pin that abuts against the detection rod 19 is detachably connected to the sliding seat 13. The middle part of the mounting plate 12 is fixedly connected to the bottom of the rotating shaft 10.

[0024] In this scheme, by rotating the mounting base 7, the detection structure is positioned above the roadbed area to be detected. The positioning pin 14 is removed, and the two sliding blocks 13 are slid so that one detection rod 19 is located at the edge of the roadbed settlement area and the other detection rod 19 is located in the roadbed settlement area. The positioning pin 14 is then reset and the sliding block 13 is locked using the positioning pin 14. The limit pin is then removed so that the detection rod 19 can only fall to the ground. The settlement height of the roadbed is measured by the height difference between the two detection rods 19.

[0025] Furthermore, in this scheme, by sliding the two slide blocks 13, both detection rods 19 can be positioned at the edge of the detection area; at the same time, the pin 11 can be removed, allowing the rotating shaft 10 to rotate, thereby rotating the mounting plate 12 to adjust the position of the detection rods 19 so that the detection rods 19 are located at the other edge of the settlement area; then the range of the settlement area can be measured by the distance between the two slide blocks 13, enabling the device to more comprehensively detect roadbed settlement data.

[0026] In this embodiment, a level 16 is provided on the support plate 9.

[0027] By setting the level 16, the level data of the support plate 9 is displayed in real time, ensuring that the support plate 9 and the mounting plate 12 are level and avoiding errors in the detection.

[0028] In this embodiment, the detection rod 19 has scale lines on its side wall (a conventional technique, so it is not shown in the figure), and the mounting plate 12 also has scale lines on its upper surface (a conventional technique, so it is not shown in the figure).

[0029] By setting scale lines, the height difference between the two detection rods 19 and the distance between the two slides 13 can be read quickly.

[0030] In this embodiment, a counterweight 17 is provided on the mounting base 7.

[0031] By setting counterweight 17, the center of gravity of the device is lowered, preventing the device from tipping over due to uneven ground.

[0032] In this embodiment, a handle 18 is provided at the top of the support column 3.

[0033] The handle 18 facilitates the handling of the testing device.

[0034] In this embodiment, a rubber pad layer is provided at the end of the detection rod 19.

[0035] A rubber pad is used to protect the end of the detection rod 19 to prevent wear on the end of the detection rod 19, which could lead to errors in the descent height data of the detection rod 19.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
