In order to achieve the above purpose, the utility model adopts the following technical scheme:

an auxiliary device for measuring bridge deformation by using a displacement meter method comprises a limiting plate, wherein a limiting hole is reserved in the middle of the limiting plate and used for limiting the reciprocating swing of a counterweight barrel; the limiting plate is provided with a level, three corners are respectively provided with a bolt hole, the three leveling bolts are connected with the limiting plate through the bolt holes, and the limiting plate is leveled and the height of the limiting plate is controlled by rotating the leveling bolts and observing the position of air bubbles in the level; three vertical supports are welded between the limiting plate and the second-layer bracket, so that the second-layer bracket and the limiting plate are always kept parallel; a displacement meter bracket is arranged on the second-layer bracket, and the displacement meter is arranged on the displacement meter bracket; the telescopic link of displacement meter contacts bottom the counter weight bucket, and thin iron wire is connected to the counter weight bucket, and thin iron wire another links to each other with gluing the hook, glues the hook and pastes on the roof beam body bottom surface.

The utility model discloses in, the displacement meter support adsorbs on two layers of brackets through self inside magnet, and on the displacement meter was fixed in the displacement meter support, the counter weight bucket hung spacing downthehole through thin iron wire, and counter weight bottom of the barrel portion contacts with the displacement meter telescopic link.

The utility model discloses in, the used material of limiting plate, vertical braces, leveling bolt and two layers of brackets is steel.

The utility model discloses in, surveyor's level quantity is one, for circular surveyor's level.

The utility model discloses in, counter weight bucket barrel is cylindrical, and upper and lower diameter is unanimous, and the external diameter is than spacing downthehole diameter little 5mm, is furnished with bucket handle and rings on the counter weight bucket, and bucket handle both ends pass through rivet connection, but free rotation with the counter weight bucket.

The utility model has the advantages of it is following:

the structure design is reasonable, the processing and the manufacture are convenient, the weight is light, and the carrying is convenient.

The limiting plate is parallel to the second-layer bracket, and the operation is simple only by leveling the limiting plate.

The height of the device can be freely adjusted through the leveling bolts, and the device has strong adaptability to places and environments.

The counterweight in the counterweight barrel can be freely added or reduced according to different field conditions.

The whole device is hollow on three sides, and the displacement meter and the reading are very convenient to install.

The displacement meter bracket is arranged on the two-layer bracket and is not limited by the unevenness of the field.

To sum up, the utility model has the advantages of reasonable design, easy installation, transfer, easy operation receives the restriction in place and environment little, and the reading is convenient, can effectively guarantee the stability and the degree of accuracy of measurement.
