It is characterized in that a surveying instrument installation fixing structure, an adjustable support structure and a base shock-absorbing structure are arranged above the support plate, and the base shock-absorbing structure includes a spring telescopic rod and a spring damper.

[0003] During use, the high-stability engineering surveying bracket base in this patent application uses the spring telescopic rod and the spring damper on the shock-absorbing structure to reduce the shock of the device base moving on uneven roads, thereby improving the protection effect of the surveying instrument. However, during such use, since the surveying instrument needs to be in a horizontal position, and the device lacks a leveling device, it is difficult to keep the surveying instrument in a horizontal position on uneven ground, reducing the practicality of the device. For this reason, we propose a high-stability engineering surveying bracket base. Utility Model Content

[0017] 1. This is a highly stable engineering surveying and mapping bracket base. By setting a lifting mechanism and a leveling mechanism, when in use, the equipment can be moved to a specified position through a brake caster and the brake caster is locked. The adjusting hand wheel is turned to drive the adjusting bidirectional threaded rod to rotate, forcing the two adjusting nut blocks threadedly connected with the adjusting bidirectional threaded rod to move closer to or away from each other. The two adjusting nut blocks drive the two adjusting rotating rods to rotate under the support of the two adjusting support rods, thereby driving the installation support frame to move up and down and driving the placement frame to adjust the height to a suitable height. Loosen the positioning bolts, and the placement frame drives the movable ball to move inside the ball-type movable sleeve through the connecting support rod under the action of its own gravity. The placing frame is placed in a horizontal position, and the connecting support rod can be rotated to drive the placing frame to rotate and adjust it to a suitable position in the horizontal direction. The positioning bolts are tightened to contact with the movable ball to complete the position fixation of the placing frame. The surveying instrument body is placed between the two positioning clamping plates inside the placing frame, and the positioning handwheel is rotated to drive the positioning two-way threaded rod to rotate, forcing the two positioning nut blocks threadedly connected to the two positioning two-way threaded rods to drive the two positioning clamping plates to approach each other to clamp and fix the surveying instrument body, and subsequent surveying and mapping work can be carried out. The above operation is simple and practical, which realizes the convenient leveling operation of the equipment on the surveying instrument body, brings convenience to the use of the equipment, and improves the practicality of the equipment.

[0018] 2. The engineering surveying and mapping bracket base with high stability is provided with rubber pads. When two positioning clamps clamp and fix the surveying and mapping instrument body, the two rubber pads enhance the clamping effect of the two positioning clamps on the surveying and mapping instrument body by deformation, thereby improving the structural stability of the equipment.
