In addition, the existing measuring devices are not convenient to adjust the measuring angle during the measurement process, which makes the measurement inconvenient.

[0003] For example: Chinese patent announcement number CN217843386U, announcement date November 18, 2022, the name of the utility model is a measuring device for easy-to-fix road and bridge construction measurement. The application discloses a road and bridge survey device, including a measuring device body, a connecting seat is provided at the bottom of the measuring device body, a support seat is provided at the bottom of the connecting seat, and a measuring lens is fixed to the outside of the measuring device body. The scheme is provided with a shielding mechanism to ensure the stability of the adjustment knob protection structure on the outside of the measuring device body, and when the shielding cover is opened, the fitting pad on the outside of the shielding cover can fit with the protective pad to ensure the stability of the placement structure and ensure the normal measurement of road and bridge construction. This scheme cannot effectively protect the measuring instrument, and the measuring device has fewer measuring angles. It is necessary to change the position of the device body to change the angle, which is extremely inconvenient to measure. Utility Model Content

[0004] The utility model overcomes the problems that the existing road and bridge surveying devices are inconvenient to store and measure, and provides a road and bridge surveying device. This scheme can store the measuring instrument to protect the measuring instrument from damage, and can also measure the measuring angle of the measuring instrument, thereby improving the convenience of road and bridge surveying.

In this solution, the lifting mechanism can adjust the height of the measuring instrument, and can realize the collection of measurement data at different height positions. At least two rotational degrees of freedom are arranged on the adjustment mechanism, so that the measuring instrument can measure at multiple angles and collect measurement data at different angles; and the box body can store the lifting mechanism, the adjustment mechanism and the measuring instrument. By lowering the lifting mechanism to the lowest position, all structures can be stored in the box body, which plays a good protective role on the device.

[0006] Preferably, the lifting mechanism comprises a fixed frame arranged on both sides of the box body, the upper and lower ends of the fixed frame are provided with transmission wheels, the transmission wheels are provided with a transmission chain, and the support frame is fixedly connected to the transmission chain. The fixed frame mainly plays a supporting role for the lifting mechanism, and two fixed frames are provided and are respectively located on both sides of the box body. The transmission wheels on the upper and lower sides of the fixed frame can drive the transmission chain to drive, thereby driving the support frame to move up and down to achieve the lifting effect.

[0007] Preferably, the fixed frame is provided with a slide groove, and the support frame is slidably connected in the slide groove. The slide groove on the fixed frame mainly guides the support frame to slide, and prevents the support frame from being unstable during the lifting process.

[0008] Preferably, the transmission wheels at the same end of the fixed frames on both sides of the box body are synchronously driven. On the two fixed frames, the corresponding driving wheels at the upper and lower ends move synchronously, so that the transmission chain can move synchronously, thereby driving the support frame to rise and fall smoothly.

[0009] Preferably, a limit plate is provided between the upper and lower driving wheels of the fixed frame, and the transmission chain passes through the limit plate. The transmission chain passes through the limit plate, which can prevent the transmission chain from shaking violently during movement, and the limit plate can limit the support frame; preventing the support frame from moving to the upper and lower ends of the fixed frame and falling off.

[0010] Preferably, the adjustment mechanism comprises a frame, the frame is fixedly connected to the support frame, a first rotating shaft with a receiving plate is rotatably connected to the frame, and the first rotating shaft rotates axially in the horizontal direction. The frame is fixedly connected to the support frame, and when the support frame is lifted or lowered, the frame is driven to be lifted or lowered together, and the first rotating shaft on the frame enables the adjustment mechanism to have a horizontal degree of rotation freedom, so that the measuring instrument can be tilted and adjusted to change the pitch angle of the measuring instrument.

[0011] Preferably, the receiving plate is rotatably connected to a second rotating shaft, the second rotating shaft is perpendicular to the receiving plate, and the measuring instrument is fixedly connected to the second rotating shaft. The receiving plate can be provided with a second rotating shaft, the second rotating shaft is perpendicular to the receiving plate, and thus the second rotating shaft is perpendicular to the first rotating shaft. The rotational freedom of the second rotating shaft makes the measuring angle of the measuring instrument more diversified, thereby increasing the measuring range of the measuring instrument.

[0012] Preferably, a plurality of fixing sleeves are evenly arranged on the outside of the box body, and a ground pin is connected to the inner thread of the fixing sleeve. The ground pin is mainly used to fix the box body structure. When measurement work is required, the ground pin is extended out of the fixing sleeve and inserted into the ground to fix the box body. When the measurement work is finished and the device is stored, the ground pin is retracted into the fixing sleeve. This can protect the ground pin, but it can also expose the ground pin to the outside and accidentally injure the operator. The telescopic action of the ground pin in the fixing sleeve can be realized by the threaded cooperation between the fixing sleeve and the ground pin.

[0013] Preferably, the upper part of the box body is rotatably connected with a box door, and a solar panel is arranged inside the box door. The box door can cover the box body to protect the measuring instrument and lifting mechanism inside. At the same time, the solar panel can provide a certain amount of electric energy for the power structure inside the surveying device, thereby improving the practicability of the device.

[0014] Preferably, the box body is further provided with a handle on the outside, and the handle on the box body facilitates the operator to carry and transport the surveying device.
