Description
Technical field
The present invention relates to one kind being applied to Borehole strain observations device more particularly to a kind of body strains such as earthquake precursor observation
Instrument erection device.
Background technology
Body strain instrument is mounted in the drilling of 60~200 meters of depths, and bore size is bigger than body strain instrument outer diameter, and body is answered
After change instrument is put into underground, need erection device that body strain instrument is fixed on drill center position, then surrounding will with cement special
Instrument and drilling palisades are coupled.If body strain instrument cannot be guaranteed that, in the center of drilling, it will cause one side water
Mud coupling layer is thicker, and another side cement coupling layer is relatively thin, influences cement coupling effect, and then influence Instrument observation data.
Original erection device is to install three rubber bars in body strain instrument base portion, and there are six Buddhist nuns for top surrounding dress
Imperial screw.The length of rubber bar is close to bore diameter, by the apexes contact the wall of a borehole of rubber bar, to ensure that instrument bottom
The heart in the borehole；After top surrounding loads onto six nylon screws, diameter is slightly less than bore diameter, also can guarantee that top is being bored in this way
Hole center, to make instrument heart position in the borehole.
There are prodigious defects for existing this mode, and three rubber bars of bottom are flexible, after instrument is put into shaft bottom,
Because body strain instrument weight is close to 40 kilograms, the elastic force of rubber bar may not necessarily make instrument bottom rebound drill center；Six of top
Nylon screw is during probe is gone into the well, it is possible to by the rock on the borehole wall to wiping off, even if not wiping off all, because
For the smooth degree gone into the well in view of instrument, probe adds the outer diameter after nylon screw to be also necessarily less than bore diameter (otherwise instrument
Will it is drilled in micro probe stone to being tangled, cause the accident of going into the well), in this way can not be in the centre bit of drilling at the top of probe
It sets.

Specific implementation mode
The embodiment of the present invention will be described in further detail below.What is be not described in detail in the embodiment of the present invention is interior
Appearance belongs to the prior art well known to professional and technical personnel in the field.
The body strain instrument erection device of the present invention, preferable specific implementation mode are：
Including shell steel cylinder, body strain instrument main body is equipped in the shell steel cylinder, which is characterized in that the body strain instrument master
It is equipped with upper holder block in shell steel cylinder above body, lower lock block is equipped in the shell steel cylinder below the body strain instrument main body；
The upper holder block is reverse taper shape, and top surface is fixed with bale handle and is equipped with compression spring, the side conical surface of the upper holder block
The side wall of corresponding shell steel cylinder is equipped with top and pushes up stick, and the inner end of top top stick is against on the side conical surface of the upper holder block,
Top top stick is equipped with top side pressure spring；
The lower lock block is cone-shaped, and top surface is equipped with lower compression spring, and bottom surface is equipped with probe mount, the side of the lower lock block
The side wall of the corresponding shell steel cylinder of the conical surface is equipped with lower part and pushes up stick, and the inner end of lower part top stick is against the side conical surface of the lower lock block
On, lower part top stick is equipped with lower part side pressure spring.
When the bale handle drawstring lifting under naturally droop state under, the upper holder block is in upper, the lower lock block
In bottom, along side, the conical surface inside contracts for the top top stick and lower part top stick, withdraws in the shell steel cylinder；
When the probe mount bottoms out, under drawstring relaxed state, the upper holder block be in bottom, the lower lock block be in it is upper
Position, the top top stick and lower part top stick are slided along the side conical surface outward, are stretched out outside the shell steel cylinder.
The body strain instrument erection device of the present invention is divided to two parts up and down, squeezes upper lower lock block by spring, is able to
Probe upper and lower part is fixed on wellhole center, keeps cement coupling layer uniform, instrument can correctly observe rock
The stress variation of conduction.
Specific embodiment：
As shown in Figure 1, erection device is divided into the top part and the bottom part point.When probe installation is gone into the well, in order to go into the well smoothly, do not allow
Probe stone blocks instrument, and stick will be pushed up by, which needing, packs up.
Kernmantle ties up on bale handle 1, and bale handle 1 and upper holder block 4 weld together, and probe drops under the action of self-weight, draws
Power is transmitted to bale handle 1 by kernmantle, and instrument is made slowly to fall, and compression spring 3 is under the action of probe dead weight and upper pulling force by crowded
Compressive strain, 4 relative probe shell steel cylinder 7 of upper holder block are up walked, and top side pressure spring 5 makes top top stick 6 withstand on upper pressure by elastic force
4 side of block is walked toward probe middle part, is withdrawn in probe.
The probe mount 13 of lower part relative probe shell steel cylinder 7 under the action of dead weight and lower compression spring 9 walks downward, lower lock block
12 be bolted with probe mount 13 together with walk downward, lower part side pressure spring 10 by elastic force make lower part push up stick 11 withstand on down
12 side of briquetting is walked toward probe middle part, is withdrawn in probe.
As shown in Fig. 2, after probe reaches foot of hole, in order to allow probe to be maintained at drill center position, upper and lower top
Stick needs to stretch out, and withstands on the borehole wall.
Pulling force on bale handle 1 and upper holder block 4 is without under the elastic force of compression spring 3, extruding upper holder block 4 walks downward, upper pressure
4 side of block ejects top top stick 6, so that top top stick 6 is withstood on the borehole wall, ensure that instrument top is in drill center.
After probe mount 13 contacts shaft bottom, probe oppresses lower compression spring 9 under the action of self-weight, and lower compression spring 9, which is squeezed, to shorten,
12 opposite shell steel cylinder of lower lock block is up walked, and 12 side of lower lock block ejects lower part top stick 11, and lower part top stick 11 is made to withstand on the borehole wall
On, it ensure that instrument lower part is in drill center.
The present invention has considerable advantageous effect compared with prior art, and body strain instrument can be made to be installed on drill center
Position provides authentic data for earthquake prediction.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
