Description
Technical field
This utility model relates to subsurface investigation technical field, a kind of sensor for below ground vibration-testing
Protection and positioner.
Background technology
Along with the expanding day with city size that develops rapidly of modern industry, vibration is to urban life environment and building ring
The impact in border has become the focus of public concern.In addition to factory, enterprise and architectural engineering, the ambient vibration that traffic system causes is asked
Inscribing oneself and become the emphasis of concern, overpass, subterranean railway, light rail transit and traffic above-ground around the most day by day form one and stand
Body space railway and highway system, the inevasible meeting of neighbouring skyscraper is affected generation slight vibration by surrounding traffic system.
Therefore the vibration-testing of building is required more and more higher by architectural design, and engineering staff needs that BUILDINGS MODELS is carried out micro-vibration and divides
Analysis, in order to study the impact on building of the long-term vibration environment, therefore the micro-vibration-testing of environment must be carried out at underground certain depth.
Carry out how sensor to certain depth by vertical drilling in the soil body, is placed at the bottom of hole and carries out by ground vibration test
Vibration signals collecting.For solving sensor water-proof, positioning, be easy to place and the problem such as recovery, in prior art, generally will vibration
Sensor and aspect sensor are fixed in metal material sealing drum, are sent at the bottom of hole by borer drill rod, at rotary drill rod
Regulation sensor levels angle to after measurement direction, reversion drilling rod, departs from sealing drum, after being completed, with cable wire by sealing drum
Take out ground.In another technology, will be fixed in metal material sealing drum by vibrating sensor, its top has an orientation to pass
Sensor storehouse, passes through latch hinged bottom aspect sensor storehouse and between vibrating sensor sealing drum, there is a cable wire in latch one end system,
Top, aspect sensor storehouse is connected by the end to end metallic rod of pin and more piece.The metal link rod using more piece to be connected will shake
After dynamic sensor sealing drum is placed at the bottom of hole, according to aspect sensor reading, adjusts vibrating sensor by rotating metallic connecting rod and survey
Examination angle.After being adjusted in place, by pulling cable wire, it is achieved aspect sensor storehouse separates with vibrating sensor sealing drum, carries out
Vibration-testing, after being completed, takes out ground by cable wire by sealing drum.
Above prior art is primarily present following deficiency:
(1), in prior art, the sealing drum equipped with sensor need to be by coupled borer drill rod or more piece phase end to end
The metal link rod connect is delivered at the bottom of hole, and by the way of rig rotates drilling rod or rotates metallic rod by manpower, passes according to orientation
Sensor indicating position angle, is adjusted to specified angle by the sensor test direction in sealing drum, then by sealing drum and drilling rod or
Metal link rod carries out vibrating data collection after disengaging.Angle is there is by the way of borer drill rod carries out the adjustment of sensor test direction
The problem that degree is difficult to control to, angle control precision is poor, by the way of the metallic rod that more piece is connected carries out measurement direction adjustment
Then there is the problem that metallic rod is heavier, connecting rod splicing is loaded down with trivial details, efficiency of the practice is low, take manpower.
(2) in prior art, for ensureing the robustness of sealing drum, sealing drum many employings metal material processing and fabricating, weight
Relatively big, strength, quantity and cooperation to test implementation personnel there are certain requirements；And processing charges is more expensive.
(3) in prior art, the data wire connecting sensor is non-dismountable, and sealing drum needs with the data wire linked together
Overall carrying, when hole depth is relatively big, data wire is longer, increases weight of equipment, carrying inconvenience.
(4), in prior art, the cable wire playing recovery sensor effect passes through fixed form with the closing cylinder equipped with sensor
Connect, non-dismountable, increase carrying difficulty.
The most all deficiencies increase the enforcement difficulty of ground vibration test to a certain extent.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is proposed that for below ground vibration-testing
Sensor protection and positioner, drive outer barrel motor to reverse by line traffic control mode, thus drives internal vibration pickup to rotate,
Realize the accurate adjustment of measurement direction.
A kind of sensor protection for below ground vibration-testing and positioner, it is characterised in that: described device bag
Including urceolus and motor, described motor is fixedly installed on the inside of described urceolus, the rotating shaft of described motor at least with one
Vertical vibration pickup and two horizontal vibration pickups constitute transmission and coordinate, between described vertical vibration pickup and described horizontal vibration pickup mutually
Vertical and spaced, described vertical vibration pickup and described horizontal vibration pickup under the driving of described motor in described urceolus
Internal rotating.
The other end in described rotating shaft is provided with the bearing matched with it, and described bearing is fixedly connected with a stock, institute
State stock bottom and be fixedly installed aspect sensor.
The data wire of described aspect sensor is connected with the data wire of vertical vibration pickup and horizontal vibration pickup merges into one
Data wire.
Described vertical vibration pickup is all connected with a water joint with the data wire of described horizontal vibration pickup.
Being fixedly installed a cable wire on described urceolus to buckle, described urceolus is buckled by described cable wire and is constituted detachable with a cable wire
The connection of formula is fixed.
Described urceolus is light-weight high-polymer material urceolus.
The utility model has the advantages that: 1) reduce handling workload: will change into by the way of lever regulated measurement direction
Being regulated by motor, and be connected by cable wire button with main equipment by cable wire, data wire is by reaching the company of IP68 classification of waterproof
Connect device to be connected with main equipment, carry separately after cable wire and data wire are detachable during carrying；Additionally, this technology uses macromolecule
Material makes sealing drum, is lighter than metal material, convenient in carrying in weight.
2) reduce vibration-testing step, shorten the testing time: regulate direction by motor, directly by cable wire, equipment is put
In at the bottom of hole, save installation, dismounting connecting rod step, save a large amount of testing time.
3) data acquisition success rate is improved: drive sealing drum motor internal to reverse by line traffic control mode, thus drive inside
Vibration pickup rotates, and reaches to adjust the purpose of measurement direction, improves the success rate of data acquisition.
4) more laborsaving in test process: new equipment is macromolecular material (such as acrylic), lightweight, so in testing
More laborsaving；When using former method to test, test equipment is lowered into hole neutralize upwards from hole take out during, connecting rod
Connection and dismounting need dismount screw, now need people and continue upward equipment of firmly catching hold of, prevent it from crashing in hole, this mistake
Cheng Shifen effort and time span are long.
5) device internal part duty it is clearly visible: sealing drum material uses macromolecular material (such as acrylic),
When using transparent macromolecular material, seen clearly the duty of internal part by transparent material.
