Description

Technical Field

[0001] The utility model relates to the technical field of benchmarks, in particular to a benchmark for engineering surveying and mapping. Background Art

[0002] Surveying and mapping engineering is a prerequisite for construction. Before construction, the height and slope of the ground need to be measured and calculated to facilitate better construction.

[0003] However, the existing benchmark is fixed to the ground. When it needs to be rotated during the surveying process, the benchmark needs to be pulled out and adjusted before being fixed. However, the position at this time may be different from the position at the last surveying, which will cause the problem of reduced measurement accuracy. Therefore, a benchmark for engineering surveying is needed to solve the above technical problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a benchmark for engineering surveying and mapping, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] As a further solution of the utility model, the adjustment component includes a servo motor fixed to the bottom wall of the adjustment box, a swing arm is fixedly connected to the servo motor, and a sliding roller is fixedly connected to the top surface of the swing arm.

[0008] As a further solution of the utility model, a fixed cross block is fixed to the top wall of the regulating box, a T-shaped slot is provided on the bottom surface of the fixed cross block, a T-shaped block is slidably connected in the T-shaped slot, a driven cross block is fixedly connected to the bottom surface of the T-shaped block, and a driven push block is fixedly connected to the bottom surface of the driven cross block.

[0009] As a further solution of the utility model, the sliding roller is slidably connected in a sliding groove provided on the bottom surface of the driven push block.

[0010] As a further solution of the utility model, the side walls of the driven horizontal block are equidistantly fixed with meshing blocks, the side walls of the fixed horizontal block are fixed with fixed plates, the fixed plate is rotatably connected to a driven rotating rod, one end of the driven rotating rod is fixedly connected to a meshing gear at the meshing point of the meshing block, and the other end of the driven rotating rod is fixedly connected to the bottom surface of the fixed block.

[0011] As a further solution of the utility model, the supporting moving assembly includes a supporting frame, a universal wheel is provided at the end of the supporting frame, an L block is slidably connected to the supporting frame, a supporting seat is fixed at the end of the L block, and a limiting plate is fixed on the supporting frame.

After the triangular block passes through the through slot, the shift block returns to its original position to complete the clamping, thereby fixing the benchmark.

[0015] 2. The servo motor drives the swing arm to rotate, and the sliding roller slides in the slide groove to push the driven push block to move in the swing direction, thereby driving the driven cross block to slide in the T-slot and make the meshing block mesh with the meshing gear. The self-rotation of the meshing gear can drive the driven rotating rod to rotate, thereby driving the plug-in fixing component to rotate. The direction of the benchmark can be adjusted without taking it out, avoiding inaccurate surveying and mapping results caused by position differences. BRIEF DESCRIPTION OF THE DRAWINGS
