Engineering supervision verticality detection device

Abstract

The invention discloses an engineering supervision verticality detection device, which belongs to the technical field of engineering supervision and comprises an operation table, two side plates are fixedly mounted at the bottom of the operation table, an arc block is fixedly mounted at the bottom of the operation table and between the two side plates, a movable cushion block is arranged between the two side plates and below the arc block, and a U-shaped top block is arranged between the movable cushion block and the arc block. Through the structural design of a movable cushion block, a threaded block, a lead screw and a U-shaped ejector block, the lead screw is rotated to drive the U-shaped ejector block to move, the lower surface of an arc block is in an arc shape, the length of the U-shaped ejector block is determined, the movable cushion block can rotate and deviate through movement of the U-shaped ejector block, one end of the movable cushion block can be high, and the other end of the movable cushion block can be low through rotation and deviation of the movable cushion block. Therefore, the ground unevenness is compensated, the function that the whole device can still keep accurate measurement under the condition that the ground is unevenness is achieved, and the problem that perpendicularity measurement is inaccurate due to the unevenness of the ground is solved.

Description

technical field [0001] The invention relates to the technical field of engineering supervision, more specifically, it relates to a verticality detection device for engineering supervision. Background technique [0002] Perpendicularity is the position tolerance, and the verticality tolerance is: the actual direction of the measured element, the maximum allowable variation between the ideal direction perpendicular to the reference, which is given on the drawing, to limit the measured actual element Deviation from the vertical direction, the maximum allowable variation range, verticality measurement is an indispensable part of engineering supervision work. [0003] However, there are still certain problems in the existing verticality detection device. For example, in the process of measurement, if the ground itself is uneven, it is easy to make the position of the alignment column and the measurement column deviate, thereby affecting the detection. Accuracy, and in the proces...
