Description
Technical field
This utility model relates to the relative of bridge security detection field, a kind of bridge and splice plate girder construction
Displacement detector.
Background technology
Relative displacement detection method and sensor are mainly based on resistor type displacement sensor and hydrostatic level at present.Electricity
Resistive displacement transducer demarcates relative displacement by the change of the resistance value that detection relative displacement causes, it is judged that relative displacement
Whether in specification allowed band, and when hydrostatic level is by measuring change in displacement, in liquid storing barrel, the change of liquid level determines
The change in displacement of measuring point.Both detection sensor bulk are relatively big, heavier mass, installation inconvenience, temperature influence are big, collection
Frequency is low, low precision.
Summary of the invention
This utility model, for overcoming the deficiencies in the prior art, designs one not temperature influence, has sample frequency high, smart
Spend the relative displacement detection device of the bridge jointing slab and girder of high feature.
For achieving the above object, design the relative displacement detection device of a kind of bridge and splice plate girder construction, including gear,
Encoder, shell, it is characterized in that: in described shell, be respectively arranged on the left side and the right side gear and encoder, described encoder twines
Being wound with steel wire rope, the left end of described steel wire rope is fixing, and the right-hand member of steel wire rope is walked around gear and exposes outside shell on the encoder,
The right-hand member of steel wire rope is provided with draw ring.
Described shell be arranged over connector, described connector is located at the top of encoder.
The bottom of described gear and the bottom of encoder are in same level.
This utility model compared with the existing technology, simple in construction, novelty, easy to use；Use mechanical type Aulomatizeted Detect
Method relative displacement is directly measured, have data precision height, strong interference immunity, data are reliable, range is big, sampling
Frequency is high, the advantages such as volume is little, easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Seeing Fig. 1, wherein, 1 is gear, and 2 is encoder, and 3 is steel wire rope, and 4 is draw ring, and 5 is shell, and 6 is connector.
Detailed description of the invention
Below according to accompanying drawing, this utility model is described further.
As it is shown in figure 1, be respectively arranged on the left side and the right side gear 1 and encoder 2 in described shell 5, described encoder 2 twines
Being wound with steel wire rope 3, the left end of described steel wire rope 3 is fixed on encoder 2, and the right-hand member of steel wire rope 3 is walked around gear 1 and exposes outside
Outside shell 5, the right-hand member of steel wire rope 3 is provided with draw ring 4.
Described shell 5 be arranged over connector 6, described connector 6 is located at the top of encoder 2.
The bottom of described gear 1 and the bottom of encoder 2 are in same level.
This utility model use time, respectively draw ring 4 and connector 6 are fixed on two pieces of adjacent bridge plates, when this two
Occur between block bridge plate that relative relief can cause connection gear 1 and encoder 2 two parts steel wire rope 3 length to change same length
Degree, owing to steel wire rope 3 is to be wound on to be connected on gear 1 and encoder 2, the change of steel wire rope 3 length can driven gear 1 and correspondence
Encoder 2 rotate angle corresponding to corresponding length, θ=Δ L/(2 π R) × 360, wherein R is tooth radius.And encoder can root
Send corresponding pulse signal according to the angle rotated, corresponding relative shift can be obtained from the pulse signal sent, and
Discrepancy in elevation symbol.The relative displacement detection device range of this practicality reaches 300mm, precision 0.04mm, and sample frequency reaches 100Hz,
More existing detection equipment precision is high, and range is big, and sample frequency is high, the most not temperature influence.
