Specific embodiment
The utility model is described in further detail below.
Embodiment: a kind of measuring device for calibrating bridge pier column center and verticality, referring to Fig. 1 and Fig. 2, including pier
Column 1, the middle position of 1 top surface of pier stud are placed in cube-shaped central block 2, vertical and symmetrical screw thread on central block 2
There are four the adjusting bolt 21 for running through central block 2, the bottom ends of adjusting bolt 21 to be fixedly connected with hemispherical by rubber for connection
Manufactured non-slipping block 211.The top surface of central block 2 is also fixedly connected with air-bubble level 22.The top surface of central block 2 is rotatably connected to
The handle 4 being vertically arranged, handle 4 protrude into the master bevel gear 41 being installed with of one end of central block 2 coaxially, the side wall of central block 2
Center sliding be connected with threaded rod 3, the bottom that threaded rod 3 stretches out one end of central block 2 is installed with vertical baffle 31；
Secondary cone tooth that is that the threaded one end that threaded rod 3 protrudes into central block 2 is connected with axis horizontal setting and being engaged with master bevel gear 41
Wheel 42, secondary bevel gear 42 are installed with the connecting cylinder 43 coaxial with secondary bevel gear 42 with the internal side wall face of central block 2 on one side,
Connecting cylinder 43 is rotatably connected on the side wall of the inside of central block 2 and by 3 grafting of threaded rod.On the top surface of central block 2
The coaxial pawl for being fixedly connected with ratchet-gear wheel 5, being fixedly connected with the cooperation of ratchet-gear wheel 5 on the top surface of central block 2 on handle 4
51。
Referring to figs. 2 and 3, the top of the side wall of threaded rod 3 offers sliding slot 32, the side of central block 2 along its axis direction
