DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-7 The utility model provides a technical solution: a foundation pit detection and calibration device that is convenient for positioning, including a fixed long cylinder 1, a laser rangefinder 2, a mounting plate 3, a mounting column 4, a mounting sleeve 5, an adjustment column 6, a movable sleeve 7, a fixed rod 8, a support plate 9, a fixed pin 10, a fixed bolt 11, an auxiliary rod 12, a positioning mechanism 13, a fixed frame 14, an auxiliary plate 15, a spring 16, a pull rod 17, a positioning plate 18 and a protrusion 19.

[0032] When using this convenient positioning foundation pit detection and calibration device, if Figure 1 , Figure 2 and Figure 4 As shown, first move the device to the foundation pit detection position, the laser rangefinder 2 is fixedly installed on the lower end of the mounting plate 3, and the upper end of the mounting plate 3 is fixedly connected with the mounting column 4. First, the mounting plate 3 drives the mounting column 4 to be inserted into the middle of the fixed long cylinder 1, and the mounting plate 3 is engaged with the lower end of the fixed long cylinder 1. Then, by rotating the mounting sleeve 5 threadedly connected to the outer surface of the mounting column 4, the mounting sleeve 5 is fitted to the upper end, thereby facilitating the limiting of the mounting plate 3 and the fixed long cylinder 1, thereby facilitating the disassembly and assembly of the laser rangefinder 2 and the fixed long cylinder 1. After the installation is completed, according to the width of the foundation pit, combined with Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, both left and right ends of the fixed long tube 1 are penetrated and connected with adjustment columns 6, and the auxiliary rod 12 is connected with the fixed long tube 1 by a slot, and the upper end of the auxiliary rod 12 is provided with a positioning mechanism 13, which includes a fixed frame 14 fixedly connected to the upper end of the auxiliary rod 12, an auxiliary plate 15 with a slot set in the middle of the fixed frame 14, a spring 16 set between the auxiliary plate 15 and the fixed frame 14, a pull rod 17 fixedly connected to the middle of the auxiliary plate 15, and a positioning plate 18 fixedly connected to the front and rear ends of the auxiliary plate 15;

[0033] By pulling the pull rod 17, the pull rod 17 slides with the fixed frame 14, and the pull rod 17 drives the auxiliary plate 15 to move upward, so that the auxiliary plate 15 squeezes the spring 16. At this time, the spring 16 undergoes elastic deformation, and the auxiliary plate 15 drives the positioning plate 18 to move upward, so that the positioning plate 18 is disengaged from the protrusion 19, thereby releasing the limit between the adjusting column 6 and the fixed long tube 1, and then by pulling the adjusting column 6, the adjusting column 6 slides with the fixed long tube 1, and the adjusting column 6 drives the auxiliary rod 12 to move with the fixed long tube 1. When the adjusting column 6 drives the support plate 9 to extend and retract outside the fixed long tube 1, the spacing between the support plates 9 on the left and right sides can be adjusted, so as to facilitate the detection of foundation pits of different sizes. When the adjustment is completed, the pull rod 17 is directly released. At this time, the spring 16 restores its elastic deformation, so that the auxiliary plate 15 drives the positioning plate 18 to move downward. The protrusions 19 are arranged at equal intervals on the side of the fixed long tube 1, and the positioning plate 18 is engaged with the protrusions 19 at the corresponding position, so as to facilitate the limit between the adjusting column 6 and the fixed long tube 1;

[0034] Then, the support plate 9 is placed on the ground above the foundation pit, and the support plate 9 drives the fixing pin 10 to be inserted into the ground, so as to facilitate the positioning of the entire detection device and improve the stability during the detection process. Then, the fixed long cylinder 1 is pulled back and forth, and the fixed long cylinder 1 drives the movable sleeve 7 to slide between the fixed rod 8 through the adjustment column 6, so as to facilitate the adjustment of the position of the laser rangefinder 2. When it is adjusted to the corresponding detection position, the foundation pit can be detected by the laser rangefinder 2. In addition, the fixing bolt 11 can be rotated. The fixing bolt 11 is threadedly connected to the movable sleeve 7. The lower end of the fixing bolt 11 is squeezed on the upper end of the fixed rod 8, which can limit the position between the movable sleeve 7 and the fixed rod 8.
