Description

Technical Field

[0001] The utility model belongs to the field of total station laying-out devices, in particular to an engineering total station laying-out device with a positioning and alignment structure. Background Art

[0002] The total station is a high-tech measuring instrument that integrates optics, mechanics and electronics. It has the characteristics of integrating horizontal angle, vertical angle, distance and height difference measurement functions. It is often used for precision engineering measurement or deformation monitoring such as large-scale above-ground buildings and underground tunnel construction. When carrying out construction projects, it is also necessary to use a line-laying device in conjunction with the total station to carry out line-laying work, which facilitates subsequent construction.

[0003] At present, the total station needs to be used with a reflective sheet during the line-laying process. Usually, the angle deviation of the total station is reset to zero first, and then the reflective sheet is moved to the measurement position. Then, multiple fixed points are performed based on the distance displayed by the instrument. Since the reflective sheet is moved manually by the staff, it is difficult to ensure straight-line movement and the moving distance is also difficult to control, which affects the speed and accuracy of the line-laying work.

[0004] Therefore, in view of the problem that the above-mentioned existing total station needs to use reflective sheets for repeated positioning when performing line-laying work, but manual operation cannot ensure that the reflective sheets move in a straight line, affecting the speed and accuracy of the line-laying work, an engineering total station line-laying device with a positioning and alignment structure is designed, so that the reflective sheet can move in a straight line when moving forward and backward and left and right, which is convenient for the total station to accurately position.

The threaded rod is driven to rotate by rotating the knobs. The setting of the two knobs enables the user to operate the knobs with both hands, thereby improving the versatility of the device.
