Detailed Description
The following describes embodiments of the present invention.
As shown in fig. 1 to 3, a measuring device for beam bridge vertical displacement include lifting rope 3, sash weight 4, percentage table 5, gauge stand 6, clamp 7, windshield 8 and iron stand 9, the one end and the beam bridge superstructure 1 of lifting rope 3 are connected, contact department at lifting rope 3 and beam bridge superstructure 1 sets up hoisting point 2 that is used for wiring lifting rope 3, this hoisting point 2 can be expansion bolts, form hoisting point 2 that can wiring lifting rope 3 through squeezing into beam bridge superstructure 1 with expansion bolts, the other end and the one end of sash weight 4 of lifting rope 3 are connected, offer in the head of sash weight 4 and be used for wiring the rings 401 of the lifting rope 3 other end. The hanging hammer 4 is positioned inside the windshield 8, and the windshield 8 is of a cylindrical hollow structure. The outer ring of the windshield 8 is held tightly by the clamp 7, and the diameter of the windshield 8 is smaller than that of the clamp 7. The clamp 7 is fixedly connected with one end of an iron frame 9, the other end of the iron frame 9 is fixedly connected with a gauge stand 6, the dial indicator 5 is fixed on the gauge stand 6, the contact head 501 is positioned at the top of the dial indicator 5, and a groove 402 used for abutting against the contact head 501 is further formed in the bottom of the hanging hammer 4. The depth of the groove 402 is 3-5 mm, and the diameter of the groove 402 is 5mm +/-1 mm.
The measurement process of the beam bridge vertical displacement by using the measurement device is as follows:
