Description
Technical field
The utility model is related to science of bridge building field of measuring technique, and in particular to a kind of bridge deflection measurement device.
Background technology
Bridge structure has deformation deformation, it is necessary to bridge structure under long-duration load effect under load action for a long time
Service behaviour and service condition are made an appraisal.Amount of deflection is the actual parameter for reflecting bridge structure behaviour in service, in prior art bar
Under part, measurement means and method can not evade geographical position residing for bridge and bring the inconvenient problem of measurement, and staff is not easy to peace
Displacement meter is filled on bridge, even if using appurtenance, staff is wasted time and energy, and personal safety has hidden danger.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bridge deflection measurement device, and the device is arranged on not
Contact at bridge and easy placement location, measurement is convenient and accurate.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of bridge deflection measurement device, described device includes base, support, fixed pulley, steel wire, plummet, displacement meter；
The device, which is arranged on, not to be contacted at bridge and easy placement location；Steel wire one end is arranged on the side position for the treatment of of bridge, and steel wire is provided with
Mark, the other end connects plummet by fixed pulley；Plummet connects displacement meter；Support includes vertical rack and horizontal stand, level
Level meter is installed on support；Vertical rack is arranged on base, is placed on below base in adjusting means.
Further, transparent shield is installed on described base, the protective cover is movably set on support, the protective cover
Measurement accuracy can be effectively improved, it is to avoid the influence of wind speed and temperature to measurement result；
Further, described adjusting means includes horizontal rotary mechanism and tilt adjustment mechanism, horizontal rotary mechanism regulation
Fixed pulley deflection, horizontal rotary mechanism drives base to rotate to an angle, and then adjusts fixed pulley steering angle so that fixed sliding
Race is parallel with steel wire, tilt adjustment mechanism adjusting base setting angle, it is ensured that base horizontal positioned, there is one at placement location
During grade, tilt adjustment mechanism serves as wedge effect.
Further, described displacement meter uses resistive strain gage sensor, and displacement signal is converted to telecommunications by displacement meter
Number, so as to measure deflection value.
The beneficial effects of the utility model are：
The utility model is simple in construction, novel in design, both can measure convenient at bridge and easy placement location not contacting
And it is accurate, labor intensity is reduced again, is effectively reduced cost of labor and is improved measurement efficiency, brings good economy
Benefit.

Support 1 includes being provided with level meter 4 on vertical rack and horizontal stand, horizontal stand；
Vertical rack is arranged on base 2, and the lower section of base 2 is placed in adjusting means 3, is provided with described base 2
Transparent shield, the protective cover is movably set on support 1, and adjusting means 3 includes horizontal rotary mechanism and tilt adjustment mechanism,
Horizontal rotary mechanism adjusts the deflection of fixed pulley 6, the setting angle of tilt adjustment mechanism adjusting base 2, it is ensured that the level of base 2 is put
Put.
Operation principle of the present utility model：
With the utility model measure 9 amount of deflection of bridge when, with protractor can read bridge 9 at diverse location with
The angle of horizontal level, measured with meter ruler steel wire 5 in end points and target location difference, so as to be asked for according to Pythagorean theorem
The position amount of deflection of bridge 9.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to the utility model
Limitation, retouching, modification or equivalent substitution that all one of ordinary skill in the art are made as described above belong to this reality
With new protection domain.
