Multi-point deflection synchronous test system for bridge

Abstract

The invention discloses a multi-point deflection synchronous test system for a bridge. The system comprises a fixed plate, a vertical rod is vertically and fixedly installed at the center position of the upper end of the fixed plate, a fixed disc is horizontally and fixedly installed at the upper end position of the vertical rod, a rotating shaft is fixedly installed at the upper end position of the fixed disc, a rotating disc is movably installed at the upper end of the rotating shaft, scale marks are arranged at the upper end of the rotating disc, a detection equipment body is fixedly installed at the upper end of the rotating disc, and a plurality of limiting holes are evenly formed in the outer side end of the rotating disc in a surrounding mode. When rotation is needed, an L-shaped rod is moved through an operation block, a spring is stretched, a clamping block is separated from the interior of a limiting hole, then a rotating disc is rotated, a specific rotation angle is determined through cooperation of a pointer and scale marks, the operation block is loosened after rotation to a proper angle, and the spring is reset to drive the L-shaped rod to reset; so that a clamping block is clamped in the corresponding limiting hole, and the position of the rotating disc is fixed.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a bridge multi-point deflection synchronous testing system. Background technique [0002] Deflection refers to the linear displacement of the rod axis in the direction perpendicular to the axis or the linear displacement of the middle surface of the plate and shell in the direction perpendicular to the middle surface when the force or non-uniform temperature changes. The linear displacement of the center of the cross-section along the perpendicular direction of the axis when the bridge deforms in bending. The deflection of a thin plate or shell refers to the displacement of each point on the midplane on the normal line to the midplane at that point. The deflection function or displacement function of each point on the object varies with position and time. The deflection is related to the magnitude of the load, the section size of the member and the physical properties of t...

Problems solved by technology

[0003] The detection of the bridge winding requires the use of detectors, but the existing detectors require special storage equipment for protection, and the operation is cumbersome when used, and the equipment needs to be rotated as a whole when rotating, which is inconvenient to rotate, and the specific rotation angle cannot be determined, so Need a kind of device badly to solve the above problems
