Description

Technical Field

[0001] The utility model belongs to the technical field of slope detection, and in particular relates to a road slope detection device. Background Art

[0002] When constructing high slopes or long retaining walls, ensuring the required slope appearance is a crucial on-site inspection method. Slope testing is a frequent requirement on sloped structures, and the quality of control during construction directly impacts the finished product's appearance. Adjustments to meet design and regulatory requirements are often necessary during construction. Relying solely on surveyors' measurements and calculations for on-site slope inspections can severely impact construction efficiency and waste personnel.

[0003] Existing CN220472634U discloses a slope detection device for road and bridge inspection, comprising a measuring instrument, a GPS fixedly mounted on the top of the measuring instrument, a display screen provided on the top of the GPS, buttons provided on one side of the display screen, a dial fixedly mounted on the front of the measuring instrument, a level fixedly mounted inside the dial, and a rotating wheel fixedly mounted on one side of the GPS;

[0004] When the detection device is placed together with other devices, the exposed detection device is easily damaged, the scale of the dial is easily worn, the level tube is easily broken under squeezing, or the display screen is scratched and cannot be used normally, resulting in serious overall loss. At the same time, when using it, it is necessary to rotate the rotating wheel to adjust the level tube, which is relatively cumbersome and the slope information cannot be observed intuitively. Summary of the Invention

[0005] The utility model provides a road slope detection device, which aims to solve the problem that when the existing detection device is placed together with other devices, the exposed detection device is easily damaged, the scale of the dial is easily worn, the level tube is easily broken under squeezing, or the display screen is scratched and cannot be used normally, resulting in serious overall loss. At the same time, when in use, it is necessary to rotate the rotating wheel to adjust the level tube, which is relatively cumbersome and cannot intuitively observe the slope information.

[0006] An embodiment of the utility model provides a road slope detection device, including a measuring instrument, which is placed in a placement box. A fixing rod is fixed to the bottom of the measuring instrument, and a rotating mechanism is installed at the bottom of the placement box. The placement box is connected to the fixing rod through the rotating mechanism.

[0007] Furthermore, a transparent plate is provided in the middle of both sides of the measuring instrument, and a cavity is formed between the transparent plates. The cavity is semicircular, and a rope is fixedly connected to the top of the cavity, and a counterweight is fixedly connected to the lower end of the rope, and a pointer is fixedly connected to the bottom of the counterweight. Scale lines are provided at the lower end of the transparent plate, and snap-fit ​​grooves are provided at the top of both sides of the measuring instrument.

[0008] By adopting the above technical solution, under the action of the counterweight, the rope will always be straightened and perpendicular to the ground, so that the staff can know the current road slope through the scale indicated by the pointer, which is intuitive and clear.

[0009] Furthermore, the total length of the rope, the counterweight and the pointer is adapted to the radius of the semicircular cavity.

[0010] By adopting the above technical solution, the rope can be controlled by the counterweight, and the pointer can point vertically to the ground no matter how steep the road is, and the pointer will not touch the bottom of the cavity and cause the rope to bend.

[0011] Furthermore, the placement box includes a cover plate 1 and a cover plate 2, and the opposite surfaces of the cover plate 1 and the cover plate 2 are provided with grooves, and the grooves are adapted to the measuring instrument.

[0012] By adopting the above technical solution, when the cover plate 1 and the cover plate 2 are put together, the measuring instrument can be placed in the groove, which can provide good protection for the measuring instrument.

[0013] Furthermore, the rotating mechanism includes cut-off tubes on the left and right sides of the bottom end of the cover plate and a rotating tube in the middle of the bottom end of the cover plate. The cut-off tubes and the rotating tube are both rotatably connected to the outer peripheral side of the fixing rod.

[0014] By adopting the above technical solution, the cut-off tube and the rotating tube can be rotated on the outer peripheral side of the fixed rod, so that the cover plate 1 and the cover plate 2 can rotate synchronously on both sides of the measuring instrument.

[0015] Furthermore, a support rod is placed in the placement box, one end of the support rod is engaged in the engagement groove, and the other end is in contact with the grooves of the cover plate 1 and the cover plate 2.

[0016] By adopting the above technical solution, when cover plate 1 and cover plate 2 are opened and laid flat on the ground, one end of the support rod can be supported in the locking groove, and the other end can be resting in the groove, thereby supporting the measuring instrument so that the measuring instrument is always in a perpendicular state to the ground.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model sets a measuring instrument. Under the action of the counterweight, the rope will always be straightened and perpendicular to the ground, so that the staff can know the current road slope through the scale indicated by the pointer, which is intuitive and clear. At the same time, under the action of the counterweight, no matter how large the slope of the road is, the pointer can point vertically to the ground, and the pointer will not touch the bottom of the cavity to cause the rope to bend.

[0019] 2. The utility model provides a placement box. When the cover plate 1 and the cover plate 2 are put together, the measuring instrument can be placed in the groove, which can provide good protection for the measuring instrument.

[0020] 3. The utility model provides a rotating mechanism so that the cut-off tube and the rotating tube can rotate on the outer peripheral side of the fixed rod, so that the cover plate 1 and the cover plate 2 can rotate synchronously on both sides of the measuring instrument.

[0021] 4. The utility model provides a support rod and a snap-fit ​​groove. When the cover plate 1 and the cover plate 2 are opened and laid flat on the ground, one end of the support rod can be supported in the snap-fit ​​groove, and the other end can be against the groove, thereby supporting the measuring instrument so that the measuring instrument is always in a vertical position to the ground.
