Detailed Description

Referring to fig. 1 to 5, the present invention will be further described with reference to the following embodiments.

The invention relates to mapping equipment, in particular to a foundation pit dividing instrument, which comprises a tripod and is characterized in that: the tripod is provided with a control device, a rotator 5 is arranged at the top of the control device and connected with the control device, the top of the rotator 5 is connected with a laser 2 through an automatic leveling device 3, the top of the laser 2 is provided with a direction lens 1, the control device is a console 6, the console 6 consists of an input module, a display module, a main control chip and an output module, the main control chip is respectively connected with the input module and the display module, one end of the output module is connected with the main control chip, the other end of the output module is connected with the rotator 5, a dividing disc 4 is further arranged between the rotator 5 and the automatic leveling device 3, the main control chip calculates the angle of the laser which needs to be rotated by applying a formula a = (180 ° -b)/2, and then the main control chip transmits the angle of the laser 2 which needs to be rotated to the rotator 5 through the output module, the rotator 5 drives the laser 2 connected with the rotator to rotate to 4 foundation pit positions respectively, and the position aligned with the laser point emitted by the laser 2 is the center of the foundation pit.

The rotation angle is input in the input module, the signals are sent to the main control chip, the main control chip converts the rotation signals into pulse signals and sends the pulse signals to the rotator 5, and the rotator 5 is controlled to rotate so as to drive the laser 2 connected to the rotator to rotate by a corresponding angle. The angle of rotation of the directional lens 1 is read by the index plate 4.

When the automatic leveling device works, the foundation pit dividing instrument is installed on a tripod, then the foundation pit dividing instrument is placed on a central pile, a power supply is started, and the automatic leveling device 3 finishes leveling to enable the laser 2 and the directional lens 1 to be kept horizontal; the direction lens 1 is rotated to be aligned with the front pile and the rotation angle is recorded, then the direction lens 1 is rotated to be aligned with the rear pile, the rotation angle of the direction lens 1 from the front pile to the rear pile can be read through the index plate 4, and then the rotator 5 transmits the rotation angle to the main control chip through the input module of the control device; the main control chip calculates the angle of the laser required to rotate by using a formula a = ± (180 ° -b)/2; then main control chip transmits the angle that laser 2 needs to rotate for circulator 5 through output module, and circulator 5 just drives laser 2 of connecting on it and rotates respectively to 4 foundation ditch positions, and the position that the laser point that laser 2 jetted out aimed at is just the foundation ditch center, and the staff can according to the position pile that the laser point identified, divide the hole work to finish.
