Abstract

The invention discloses a bridge deflection measuring device which comprises a dial indicator, a jacking mechanism, a sliding mechanism and a control mechanism. The jacking mechanism comprises a base,a jacking gear rotationally arranged on the base, a jacking motor used for driving the jacking gear to rotate, a rack meshed with the jacking gear, a shear fork rod and a top platform hinged to the top of the shear fork rod. The rack is in sliding connection with the base and hinged to one end of the bottom of the shear fork rod, and the other end of the bottom of the shear fork rod is hinged with the base; the sliding mechanism comprises at least two lead screws rotationally arranged on the top platform, a sliding trolley forming a threaded motion pair with the lead screws and a sliding motor used for driving the lead screws to rotate, the lead screws are arranged in parallel, and the dial indicator is fixed to the sliding trolley; the control mechanism comprises a controller, and the jacking motor and the sliding motor are electrically connected with the controller. The device provided by the invention greatly facilitates the measurement of the deflection of a bridge.

Description

technical field [0001] The invention relates to the technical field of building deflection measurement, in particular to a bridge deflection measurement device. Background technique [0002] The safety of the bridge must be evaluated after completion acceptance and service for a certain number of years. Static and dynamic load tests are usually carried out during the safety evaluation. An important content of the static load test is to measure the deformation of the structure, that is, the deflection. The method is generally to use a dial indicator for detection. [0003] In the prior art, the dial indicator is usually measured by contacting the bottom of the bridge during detection, but because the height of the bottom of the bridge is high, the surveyor needs to use a jacking mechanism and carry the dial indicator to the bottom of the bridge. Measure again; adopt this method to measure very inconveniently, and there are following problems: [0004] 1. It is not convenien...
