Description
Technical field
The invention belongs to Crack Detection equipment technical fields, relate in particular to the simple displacement monitor in crack.
Background technique
After massif, Dangerous Rock Body, building and road and bridge are formed, the crack moment of development was seriously threatened to week in crack
The safety of life and property of the side people, so needing real-time fracture to be monitored, in order to prevent safety accident
And the loss of property.The artificial simple monitoring of the tools such as tape measure, this side is usually taken in the monitoring in the crack for developing
Method has that the precision of measurement is low, cannot obtain monitoring data in real time, has certain subjective factor to dominate, can not be accurate
The developmental condition in crack is recorded, this will cause serious shadow to the reasonable moment of the selection for the measure prevented and reduced natural disasters and arrangement measure
It rings.
There are also some measuring devices for designing for crack at present, although solving, above-mentioned there are measurement accuracy
The problem of low, real-time monitoring, but its equipment has that structure is excessively complicated, inconvenient for use.
Summary of the invention
This is of the invention to aim to overcome that disadvantages mentioned above, and a kind of structure provided is simple, real-time monitoring, measurement accuracy
The simple displacement monitor in high crack.
It the purpose of the present invention and solves its technical problem underlying and adopts the following technical solutions to realize:
The simple displacement monitor in a kind of crack of the invention, including column A, column B, the graduated disk of mark and measuring scale,
In: column B is fixedly mounted shaft A, and shaft A is successively fixedly mounted disk, activity installation measuring scale and needle dial, measuring scale and refers to
Dials is fixedly connected, and shaft B is fixedly mounted in column A, and the slot activity of shaft B activity installation activity block, measuring scale and movable block is hung down
After straight cooperation and stretch out movable block.
The column A, the unilateral setting chamfering in the one end column B.
The measuring scale and the unilateral setting chamfering of movable block abutting end.
Four side slot activities of the measuring scale and movable block cooperate.
The movable block is coupled with the one end shaft B using cambered surface.
Compared with prior art, the present invention having apparent beneficial effect, from above-mentioned technical solution: of the invention
Disk, activity installation measuring scale and needle dial is successively fixedly mounted in the movable block and shaft A of activity installation on column A, realizes
The real-time monitoring of fracture, measurement accuracy are high；Since the component of this structure composition is few, shape is uncomplicated, so that device structure
Simply, it is easy to use；Column A, the unilateral setting chamfering in the one end column B, in favor of installing and using；Measuring scale and movable block abutting end
Unilateral setting chamfering, in favor of equipment assembly；Four side slot activities of measuring scale and movable block cooperate, and avoid sundries measuring scale and work
Motion block fit clearance improves the accuracy of measurement data；Movable block is coupled with the one end shaft B using cambered surface, raising activity
Precision when block rotates, improves the precision of measurement data.

Specific embodiment
The technical solution of the simple displacement monitor in crack for a better understanding of the present invention, below in conjunction with attached drawing and preferably implementation
Example, to mode, structure, feature and its effect, detailed description are as follows.
Referring to Fig. 1, the simple displacement monitor in a kind of crack of the invention, including column A1, column B2, the graduated circle of mark
Disk 4 and measuring scale 5, in which: shaft A3 is fixedly mounted in column B2, and disk 4, activity installation measuring scale is successively fixedly mounted in shaft A3
5 and needle dial 6, measuring scale 5 be fixedly connected with needle dial 6, column A1 be fixedly mounted shaft B8, shaft B8 activity installation activity block
7, after the slot moveable vertical cooperation of measuring scale 5 and movable block 7 and stretch out movable block 7.
The column A1, the unilateral setting chamfering in the one end column B2, are easily installed column when in use, as shown in Figure 1.
The measuring scale 5 and the unilateral setting chamfering of 7 abutting end of movable block, so that measuring scale 5 and movable block 7 are installed, such as
Shown in Fig. 1.
Four side slot activities of the measuring scale 5 and movable block 7 cooperate, between avoiding sundries measuring scale 5 and movable block 7 from cooperating
Gap improves the accuracy of measurement data, as shown in Figure 3.
The movable block 7 is coupled with the one end shaft B8 using cambered surface, and precision when movable block 7 rotates, such as Fig. 4 are improved
It is shown.
Working principle: referring to Fig. 1-4, matching part movable on the simple displacement monitor in the crack assembled is smeared into lubrication
Agent, the unilateral end of column B2 chamfering is fixedly installed to the fixed soil in crack or building body surface, the unilateral end of column A1 chamfering are fixed
It installs and remembers the pointer tip on needle dial 6 to it, with disk 4
Record is installed data shown in backpointer disk 6 and measuring scale 5, after the soil or building body of crack movement move, column
A1 is moved with it, and the smooth motion in the case where cooperating with shaft B8 cambered surface of movable block 7, measuring scale 5 hangs down with 7 side of movable block always
Directly, smooth sliding occurs in the four side slots with movable block 7 for measuring scale 5 at this time, while being fixedly connected with 5 other end of measuring scale
Needle dial 6 rotates, after mobile stop occurs for the mobile soil in crack or building body, by the data preparation of real-time monitoring,
It calculates to obtain the opposite width in crack both sides and height using trigonometric function.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form, appoint
What is to the above embodiments according to the technical essence of the invention any simply to repair without departing from technical solution of the present invention content
Change, equivalent variations and modification, all of which are still within the scope of the technical scheme of the invention.
