The measuring points are marked obviously on the top plate and numbered uniformly, the positions of the points are encircled by red paint or white paint, and the numbers are marked on the roadway sides of the measuring points obviously, so that the use is convenient.
As the underground measuring points are arranged on the top plate of the roadway, the total station needs to be centered under the measuring points, when the total station is centered under the measuring points, the instrument needs to be leveled, a down-hanging ball is hung on the measuring points, and the total station is moved to enable the center of the point of the total station to be aligned with the tip of the down-hanging ball. However, due to the influence of large wind flow in the roadway and short side length of the underground measuring point, great attention needs to be paid to centering of the total station and the target so as to reduce the adverse influence of the total station and the target on the angle measuring precision.
The utility model has the following contents:
the utility model discloses the purpose is exactly in order to compensate prior art's defect, provides a portable rimq device is measured to centering under tunnel measurement point, convenient equipment, portable can block the distinguished and admirable that the vertical ball rocked in the tunnel during its use to can guarantee that accurate, quick centering is measured.
The utility model discloses a realize through following technical scheme:
the utility model provides a portable rimq device is measured in centering under tunnel survey point which characterized in that: the telescopic link that sets up including two symmetries, the telescopic link is suit formula structure, and it is including inner tube and outer tube, and the outer tube is located the below, the lower tip of inner tube and the upper end of outer tube do not are equipped with the locating hole that the interval set up, and close the set screw in the locating hole soon, the bottom portion of telescopic link is connected fixedly through horizontal connecting rod and the strengthening rib of cross arrangement, horizontal connecting rod is located the bottommost, installs the braces between the upper end of two strengthening ribs and the horizontal connecting rod, the both ends tip of telescopic link is equipped with the couple respectively, the couple is used for fixed windshield cloth, four corners of windshield cloth distribute and have the hanging hole.
The two ends of the reinforcing rib are respectively connected with the outer pipe body side walls of the bottom end parts on the two sides, and a hook used for fixing the reinforcing rib is installed on the outer pipe body side wall.
The two ends of the horizontal connecting rod are respectively provided with external threads, the side wall of the outer tube body corresponding to the installation position of the horizontal connecting rod is provided with a fixed rod in butt joint with the horizontal connecting rod, the diameters of the horizontal connecting rod and the fixed rod are the same, the fixed rod is distributed with the external threads, and the fixed rod is screwed with a fixed sleeve.
The both sides of wind-break cloth distribute the solid fixed ring that is used for fixed wind-break cloth that the interval set up, gu fixed ring's diameter is greater than the directness of outer tube, and can guide on the inside and outside body of telescopic link and remove.
The principle is as follows: through the structure of telescopic tube, can satisfy the requirement of co-altitude, and insert set screw through the locating hole between inner tube and the outer tube and fix spacingly, structure through the strengthening rib of cross arrangement is when increasing its bulk strength, can guarantee that it withdraws folding performance, structure through horizontal connecting rod can further strengthen stability between, structure through the braces, can facilitate the use, the people's back can to the tunnel measurement station at the back during use, back to the windward side, let the wind current blow along support both sides through the cloth that keeps out the wind, the plumb bob rocks and reduces, can block the wind current that influences the plumb bob and rocks in the tunnel better, thereby guarantee to carry out accurate centering flattening to total powerstation or target fast.
The utility model has the advantages that:
the utility model has the advantages of reasonable design, convenient equipment, portable can block the wind current that influences the plumb bob and rock in the tunnel during its use to can guarantee that accuracy, quick centering are measured, satisfied measuring operation requirement.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the wind-blocking cloth.
The specific implementation mode is as follows:
