Even if the device itself is not on a horizontal plane, the measuring instrument can automatically adjust to keep horizontal. Then, by rotating the rotating block, the threaded groove is threadedly connected to the spiral thread, thereby fixing the angles of the movable ring and the hemispherical body, ensuring its stability, avoiding the shaking of the measuring instrument caused by accidentally touching the device during the measurement process, enhancing the safety and reliability of the operation, making the measurement work smoother and more efficient. By referring to the protractor, the operator can accurately adjust the angle of the hemispherical body to ensure that the measuring instrument reaches the required measurement angle, flexibly coping with different terrains and environmental conditions, and ensuring that the measuring instrument can adapt to various measurement scenarios.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] As Figures 1-6 shown, the present utility model provides a technical solution: a road surveying tool for highway engineering, including a mounting seat 1. The inner bottom surface of the mounting seat 1 is fixedly connected with a motor 2, the output end of the motor 2 is fixedly connected with a lead screw 3, the lead screw 3 is in threaded connection with a movable seat 4, the outer wall of the movable seat 4 is movably connected with the inner wall of the mounting seat 1. The mounting seat 1 limits the movable seat 4 so that the movable seat 4 can only move longitudinally. The top end surface of the movable seat 4 is provided with a horizontal component, and the horizontal component includes a rotating shaft 5, a cross plate 6, a bracket 7, an annular frame 8, a connecting rod 9, a thread groove 10, a rotating block 11, a movable ring 12, a hemispherical body 13, a measuring instrument 14, a protractor 15, a bolt 16, a rotating seat 17, a threaded rod 18, a limit post 19, and a rubber pad 20.

[0027] In an embodiment of the present utility model, a rotating shaft 5 is fixedly connected to the top end face of the movable seat 4. The rotating shaft 5 is rotatably connected to the cross plate 6. A bracket 7 is fixedly connected to the top end face of the cross plate 6. The bracket 7 is fixedly connected to the annular frame 8. A threaded groove 10 is formed in the side wall of the connecting rod 9. The threaded groove 10 is threadedly connected to the annular frame 8. The connecting rod 9 is sleeved with the movable ring 12. The connecting rod 9 is fixedly connected to the rotating block 11. By rotating the rotating block 11, the threaded groove 10 is threadedly connected to the spiral thread, so as to fix the angles of the movable ring 12 and the hemispherical body 13. The inner wall of the movable ring 12 is fixedly connected with spiral threads. The connecting rod 9 is threadedly connected to the movable ring 12. The connecting rod 9 is sleeved with the hemispherical body 13. The inner wall of the hemispherical body 13 is fixedly connected with spiral threads. A measuring instrument 14 is fixedly connected to the bottom end face of the hemispherical body 13. A protractor 15 is fixedly connected to the top end face of the movable ring 12. By referring to the protractor 15, the angle of rotation of the hemispherical body 13 is manually adjusted to meet the requirements of on-site measurement of highways.

[0028] A bolt 16 is threadedly connected to the top end face of the cross plate 6. The cross plate 6 is rotatably connected to the rotating seat 17. The inner wall of the rotating seat 17 is threadedly connected to the threaded rod 18. The top end face of the limiting column 19 is movably connected to the rubber pad 20 through a connecting ball. The limiting column 19 is fixedly connected to the top end face of the cross plate 6. The limiting column 19 is sleeved with the threaded rod 18.

[0029] The motor 2 starts to drive the lead screw 3 to rotate, and the movable seat 4 moves longitudinally to adjust the height of the measuring tool. The cross plate 6 is rotated to make the cross plate 6 rotate around the rotating shaft 5 to adjust the horizontal angle of the measuring tool. The bolt 16 is rotated to make the bolt 16 abut against the movable seat 4, thereby fixing the horizontal angle of the measuring tool.

[0030] Due to the action of gravity, when the device is not horizontal, the measuring instrument 14 drives the hemispherical body 13 and the movable ring 12 to rotate, so that the hemispherical body 13 and the movable plate 12 rotate around the connecting rod 9, thereby keeping the measuring instrument 14 always in a horizontal state, ensuring the accuracy of the measurement results. Even if the device itself is not on a horizontal plane, the measuring instrument 14 can automatically adjust to be horizontal. Then, by rotating the rotating block 11, the threaded groove 10 is threadedly connected to the spiral thread, thereby fixing the angles of the movable ring and the hemispherical body 13, ensuring its stability, avoiding the shaking of the measuring instrument 14 caused by accidentally touching the device during the measurement, enhancing the safety and reliability of the operation, and making the measurement work smoother and more efficient.

[0031] When manual adjustment of the angle of the measuring instrument 14 is required, by referring to the protractor 15, the operator can accurately adjust the angle of the hemispherical body 13 to ensure that the measuring instrument 14 reaches the required measurement angle, flexibly cope with different terrains and environmental conditions, and ensure that the measuring instrument 14 can adapt to various measurement scenarios.

[0032] In addition, the horizontal plate 6 is rotatably connected to the rotating seat 17. The inner wall of the rotating seat 17 is threadedly connected to the threaded rod 18. The top end surface of the limiting column 19 is movably connected to the rubber pad 20 through a connecting ball. By rotating the rotating seat 17, the threaded rod 18 moves upward, and the rubber pad 20 abuts against the hemispherical body 13, thereby fixing the measuring instrument 14. This enables the measuring instrument 14 to be adjusted to the most compact and stable state before transportation, ensuring safety during transportation and reducing the risk of damage caused by jolts or uneven transportation.

[0033] In the present utility model, during use, the motor 2 drives the lead screw 3 to rotate, and the movable seat 4 moves longitudinally. Rotate the horizontal plate 6 to make the horizontal plate 6 rotate around the rotating shaft 5. Rotate the bolt 16 to fix the horizontal plate 6. Due to the action of gravity, the hemispherical body 13 and the movable plate 12 rotate around the connecting rod 9, causing the measuring instrument 14 to always remain in a horizontal state. The thread groove 10 is threadedly connected to the spiral thread to fix the angle between the movable ring and the hemispherical body 13. Rotate the rotating seat 17 to make the threaded rod 18 move upward, and the rubber pad 20 abuts against the hemispherical body 13 to fix the measuring instrument 14.

[0034] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
