Abstract
The utility model discloses an anchor dynamometer, including a high strength steel body, a strain gauge, a protecting end cover, an aviation plug, and an O-style seal ring, characterized in that the strain gauge is bonded in a groove of the high strength steel body and is sealed with sealant to prevent water; the aviation plug connects the strain gauge in the high strength body to a resistor in the receiving device and forms an electric bridge; the O-style seal ring is fixed on the protecting cover which is connected with the high strength steel body through a thread to perform the protection from water and moisture; the change of the high strength steel body results the change in resistance of the strain gauge. The utility model has the advantages of high measuring accuracy, convenient installation, and is convenient for engineering measurement.
Description
Technical field
The utility model relates to a kind of measuring instrument, particularly a kind of in the mine, department's Geotechnical Engineering anchor pole, cable bolting design, safety monitoring, mechanism such as building, electric power, water conservancy, railway, military project studies indispensable anchor dynamometer.
Background technology
The cable bolting design is widely used in colliery tunnel support, dam and stabilization of dam foundation, slope treatment, underground works, industry and covil construction isolith geotechnique journey, has obtained huge social and economic benefit.The unstable failure of Geotechnical Engineering all has evolution from gradual transformation to mutation, and generally the intuition only according to people is indiscoverable, need monitor by instrument.Anchor dynamometer can measure the stressed size of anchor cable (anchor pole) at any time, for the mechanism of action of research anchor cable in above-mentioned engineering, the rationality of the safe reliability of evaluation engineering and supporting design is all significant, the rigidity dynamometer comprises types such as strain chip dynamometer and steel chord type force-measuring meter, the utility model provides a kind of strain chip dynamometer, especially a kind of have measuring accuracy height, an anchor dynamometer easy for installation.
Summary of the invention
The purpose of this utility model provides a kind of strain chip dynamometer, especially a kind of measuring accuracy height, anchor dynamometer easy for installation.
The technical solution of the utility model is achieved in that anchor dynamometer comprises: the plow-steel body; foil gauge; the protection end cap; aviation plug; the O RunddichtringO is formed; it is characterized in that; described foil gauge is bonded in the groove of plow-steel body; and use the fluid sealant water-tight; thereby aviation plug is connected the foil gauge in the plow-steel body and forms electric bridge with resistance in the receiving trap; the O RunddichtringO is fixed on the protection end cap; protection end cap and plow-steel body are threaded; carry out waterproof and dampproof protection, the variation of plow-steel body causes the change of the resistance of foil gauge.
Described anchor dynamometer is rectangular parallelepiped.
The concrete course of work: anchor dynamometer before use, be connected with receiving device by aviation plug, read initial reading and record, anchor dynamometer is installed in the end of anchor cable, thereby causing the distortion of plow-steel body, the variation of anchor dynamometer load make the resistance value of foil gauge change, by the aviation plug foil gauge resistance value of record after changing that be connected with receiving device, according to the result of laboratory demarcation and the difference of resistance strain gage, finally determine the size of anchor dynamometer load then.
Advantage of the present utility model:
1. the utility model is simple in structure, and it is convenient to install, and cost is lower;
2. the utility model is owing to used the structure of strain chip, and measurement result is accurate;
3. the utility model volume is little, carries lightly, can carry out the collection of data at any time, is monitoring instrument the most practical in the Geotechnical Engineering.
4. the utlity model has the characteristics that rigidity is big, dynamic perfromance is good, and various antijamming capability is very strong, its linearity all is very desirable under any condition simultaneously.In addition, the utility model cost performance is very high.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model anchor dynamometer.
Embodiment
Below in conjunction with embodiment the technical solution of the utility model is described further:
As shown in Figure 1; anchor dynamometer comprises: plow-steel body 1, foil gauge 2, protection end cap 3, aviation plug 4; the O RunddichtringO forms 5; it is characterized in that; described foil gauge 2 is bonded in the groove 6 of plow-steel body 1; and use the fluid sealant water-tight; aviation plug 4 is connected the foil gauge 2 in the plow-steel body 1 with resistance in the receiving trap; form electric bridge; O RunddichtringO 5 is fixed on the protection end cap 3; protection end cap 3 and plow-steel body 1 are threaded, and carry out waterproof and dampproof protection, and the variation of plow-steel body 1 causes the change of the resistance of foil gauge 2.
The concrete course of work: anchor dynamometer before use, take off protective cover 3, measure initial reading, buckle well protective cover 3, be connected with receiving device by aviation plug 4, read reading and record, anchor dynamometer is installed in the end of anchor cable, the drag-line tool rises, make the resistance value of foil gauge 2 change thereby the variation of anchor dynamometer load causes the distortion of plow-steel body 1, accept foil gauge 2 resistance values after instrument record changes, then the result who demarcates according to the laboratory and the difference of resistance strain gage 2 by aviation plug 4, the final size of determining anchor dynamometer load, thus realize engineering is monitored in real time.
Claims (2)
1. anchor dynamometer comprises: plow-steel body, foil gauge, protection end cap, aviation plug; the O RunddichtringO is formed; it is characterized in that; described foil gauge is bonded in the groove of plow-steel body; and use the fluid sealant water-tight, aviation plug is connected the foil gauge in the plow-steel body with resistance in the receiving trap, form electric bridge; the O RunddichtringO is fixed on the protection end cap, and protection end cap and plow-steel body are threaded.
2. anchor dynamometer as claimed in claim 1 is characterized in that described anchor dynamometer is rectangular parallelepiped.
