Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.Following examples are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As shown in Fig. 1 is to 7, a kind of bridge three direction displacement long term monitoring device, including：
Pedestal 4, for being connected with abutment/bent cap 13 side；
A pair of expansion link 3, is respectively perpendicular the two ends being arranged on pedestal 4, and its upper horizontal is provided with connecting bolt 2；
Monitoring flat board 1, for being connected with plate-girder 10 bottom surface, it is by the separable expansion link 3 that is arranged on of connecting bolt 2
Top enable its go to when not working parallel with expansion link 3 in order to carry, its be foursquare transparent plastic sheet, its monitoring
Surface is provided with cross grid graduation mark；
And movable pointer, it is installed vertically on pedestal 4, and during monitoring, its top can be with the monitoring of detection flat board
Contact is moved on surface.
Movable pointer includes：
Pointer sleeve pipe 8, its movable set realizes the regulation of its height on pedestal 4 and by a push-and-pull bar 9, and pedestal is opened
It is provided with push/pull slot 7 to accommodate push-and-pull bar；
Pointer body 5, its movable set, in pointer sleeve pipe 8, its outer wall is provided with graduation mark to show height monitoring
Value；
And spring 6, it is set in pointer sleeve pipe 8, and its top is connected with pointer body 5, bottom and pointer sleeve pipe 8 connect
Connect, thus make pointer body 5 can move with the monitoring surface of monitoring flat board 1 all the time during monitoring contacting.
