Abstract
The utility model relates to a kind of calibrate AE sensor coupling device, particularly a kind of calibrate AE sensor pushing tow coupling device, is mainly used in acoustic emission detection sensor in Geotechnical Engineering and installs.The sensor of this device is placed between grip block and lower grip block and clamps with standing screw and nut screwing clamping, fixing and standing screw homoaxial bottom push rod on lower grip block, fixing and the homoaxial pushing tow screw rod of standing screw on upper grip block, pushing tow screw rod upper end is screwed into band nut pushing tow pipe.The utility model structure is simple, can make full use of angle position and the surface relief feature of measurand, comparatively easily sensor can be mounted on tested point.
Description
Technical field
The utility model relates to a kind of calibrate AE sensor coupling device, particularly a kind of calibrate AE sensor pushing tow coupling device, is mainly used in acoustic emission detection sensor in Geotechnical Engineering and installs.
Background technology
In the Geotechnical Engineerings such as mining, usually need to monitor the stability of rock mass, wherein the acoustic emission monitor(ing) of rock mass is one of important means.During monitoring, fixation is buried in be usually adhesively fixed method, bolt and hanger in place and the boring of the installation coupling scheme of calibrate AE sensor underground, and these methods all have its good and bad point and adaptability.
For the object that need carry out long term monitoring or deep monitoring, usually adopt well cementing Embedment and installation, sensor only can make single use.
For when the surface mount sensor of detected object, be adhesively fixed method more for convenience, its shortcoming is relevant to the set time of bonding agent.Usually, the bonding agent solid filling less (502 glue as conventional) that set time is short, this just requires the smooth smooth finish that bonding plane reaches certain, the constant intensity that guarantee is certain, but the monitoring target surface in Geotechnical Engineering is mostly coarse can't bear, and usually increases workload because needs carry out repairing; And for the more bonding agent of the solid filling being adapted to the coarse bonding plane of out-of-flatness, its set time is usually longer, can not detect in time; Bolt and hanger in place need on detected object, to bury bolt underground in advance, and it is also longer that it buries the set time underground, and at measuring point indefinite or how temporarily measuring point, need to bury set bolt underground in a large number, make troubles equally.
Under normal circumstances, in Geotechnical Engineering, all there are some angle positions in measuring point to be checked, such as, each angle position etc. in the angle position of the angle position of the corner, both sides (drift angle, base angle) in tunnel, limit, goaf nation and base plate or top board, ore pillar and base plate or top board and the local angle position formed by the large rock mass extremely given prominence to, chamber, and its surface is normally extremely irregular.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of emission sensor pushing tow coupling device, and this device can make full use of angle position and the surface relief feature of measurand, comparatively easily sensor can be mounted on tested point.
The technical scheme that the utility model adopts is: sensor is placed between grip block and lower grip block and clamps with standing screw and nut screwing clamping, fixing and standing screw homoaxial bottom push rod on lower grip block, fixing and the homoaxial pushing tow screw rod of standing screw on upper grip block, pushing tow screw rod upper end is screwed into band nut pushing tow pipe.
Described standing screw is through the marginal position of upper and lower grip block, and pushing tow screw rod and bottom push rod lay respectively at the center of grip block and lower grip block.
The standing screw of described upper grip block upper end is also equipped with one parallel with upper grip block and leave the push plate in gap, the sensor of this scheme Suitable Zones end leads, leaves the space of end leads and joint between push plate and upper grip block.
The invention has the beneficial effects as follows: there is angle at measurand position to be detected and under air spots shelf-regulating Conditions, calibrate AE sensor can be fixedly mounted easily in detected part, and dismounting is very convenient.
Accompanying drawing explanation
Fig. 1 is one of the utility model structural representation.
Fig. 2 is another structure using state schematic diagram of the utility model.
In figure, each label is: upper grip block 1, lower grip block 2, standing screw 3, nut 7, sensor 8, sensor lead 9, pushing tow screw rod 4, band nut pushing tow pipe 5, bottom push rod 6, push plate 10, measurand 11.
Embodiment
See Fig. 1,2, sensor 8 is placed in grip block 1 and lower grip block 2, and the edge of upper and lower grip block is processed with mounting hole, penetrates standing screw 3 and sensor 8 is tightened clamping by nut 7.Lower grip block 2 is fixed with and standing screw 3 homoaxial bottom push rod 6, upper grip block 1 is also fixed wtih pushing tow screw rod 4 in the same way, pushing tow screw rod 4 upper end has been screwed into band nut pushing tow pipe 5.For the sensor of strap end portion lead-in wire, the standing screw 3 of upper grip block 1 upper end is also equipped with one piece of push plate 10 parallel with upper grip block 1, and leaves gap between two plates, this gap is the space of sensor lead 9 and joint.
Claims (3)
1. a calibrate AE sensor pushing tow coupling device, it is characterized in that: sensor is placed between grip block and lower grip block and clamps with standing screw and nut screwing clamping, fixing and standing screw homoaxial bottom push rod on lower grip block, fixing and the homoaxial pushing tow screw rod of standing screw on upper grip block, pushing tow screw rod upper end is screwed into band nut pushing tow pipe.
2. by calibrate AE sensor pushing tow coupling device according to claim 1, it is characterized in that: standing screw is through the marginal position of upper and lower grip block, and pushing tow screw rod and bottom push rod lay respectively at the center of grip block and lower grip block.
