[0002] A total station, also known as a total station electronic distance meter, is a high-tech total station instrument that integrates optics, mechanics and electronics. It is a surveying and mapping instrument that integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measurement functions. A total station is needed in highway survey and design.

[0003] When using existing total stations, most of them are installed on tripods. However, because the outdoor terrain is relatively complex and the positions where the total stations need to be placed are different, the angles are easily offset when placed. Therefore, the tripod needs to be adjusted, and the total stations on the two tripods need to be adjusted to be relative, which is very cumbersome and inconvenient for the calibration of the total station. Therefore, it is necessary to propose a highway survey and design measurement device. Summary of the invention

[0019] A U-shaped limit block 17 is fixedly installed inside the protective cover 16 , the lower end of the U-shaped limit block 17 is arranged in an inclined shape, and a U-shaped pad 18 is fixedly sleeved inside the U-shaped limit block 17 , and the U-shaped pad 18 is sleeved on the total station 14 .

[0020] A fixing ring 27 is fixedly installed at one end of the connecting rope 26 outside the protective cover 16 , and the connecting rope 26 and the fixing rod 24 can be pulled by the fixing ring 27 .

[0021] The side of the positioning block 43 away from the rubber pulling block 42 is arranged in an arc shape, and the arc of the positioning block 43 matches the outer wall of the ball 13, so that the positioning block 43 can be fixed when it is pushed to abut against the ball 13.

[0022] The positions of the pushing groove 44 and the pushing hole 45 are opposite to the position of the threaded sleeve 33 , so that the threaded sleeve 33 and the threaded rod 34 will be opposite to the pushing groove 44 and the pushing hole 45 after rotating and adjusting their directions.

[0023] Among them, the axis lines of the total station 14, the ball 13 and the hook 15 are arranged to overlap, and the protective cover 16 is hung on the lower end of the ball 13 through the hook 15. At this time, the protective cover 16 will fall downward under its own weight and pull the ball 13 through the hook 15, so that the hook 15 and the total station 14 remain vertical.

[0024] Among them, a calibration protrusion is set at the lower end of the protective cover 16, and the calibration protrusion is clamped in the installation groove 31. The protective cover 16 can be positioned by clamping the calibration protrusion and the installation groove 31 to facilitate the alignment of the thread groove 35 and the threaded rod 34.

[0025] The lower surface of the fixing base 11 is provided with a mounting screw hole, and the fixing base 11 is mounted on the tripod by means of a mounting bolt which is threadedly connected to the mounting screw hole.

[0026] When in use, first place the tripod at the measuring position and adjust the mounting platform at its top to a relatively flat state, then place the fixing base 11 on the mounting platform of the tripod, and then thread the fixing base 11 with the mounting screw hole through the mounting bolt, so as to install the fixing base 11 on the tripod. At this time, the threaded rod 34 can be rotated by turning the handle 36, so that the threaded rod 34 drops and disengages from the threaded groove 35, thereby releasing the fixation of the protective cover 16. At this time, the protective cover 16 can be removed and the total station 14 can be leaked out, and then the connecting rope 26 is pulled through the fixing ring 27, and the connecting rope 26 pulls the fixing rod 24 back into the moving groove 22, and the fixing groove 21 is emptied. At this time, align the fixing groove 21 on the protective cover 16 with the hook 15, and lift the protective cover 16 so that the hook 15 is inserted into the fixing groove 21, and then loosen the fixing ring 27. At this time, the spring 23 will push the fixing rod 24 to insert into the fixing groove 21, thereby fixing the hook 15 in the fixing groove 21 and hanging the protective cover 16. At the lower end of the ball 13, the protective cover 16 will fall downward under its own weight and pull the ball 13 through the hook 15, so that the hook 15 and the total station 14 remain in a vertical state, and then the ball 13 and the total station 14 can be rotated to adjust the direction, so as to facilitate the calibration of the total station 14. After the calibration is completed, the threaded sleeve 33 and the threaded rod 34 can be rotated by the rotating shaft 32, so that the threaded sleeve 33 and the threaded rod 34 are rotated to a position opposite to the push hole 45. At this time, the threaded rod 34 is rotated by rotating the handle 36, so that the threaded rod 34 moves in the threaded sleeve 33, and is inserted into the push groove 44 through the push hole 45, and the positioning block 43 is pushed to move by abutting against the push groove 44, and the positioning block 43 moves to abut against the ball 13 to clamp and fix it, so that the total station 14 is supported after the ball 13 is clamped and fixed, so that the total station 14 maintains the direction angle, making the angle and direction adjustment of the total station 14 simpler and more convenient.
