Description
Technical field
The utility model relates to the device for measuring force of the tensile property of anchor pole in a kind of test base or bolt, the particularly a kind of location steering ball that can proofread and correct the dynamometry deviation.
Background technology
No matter be that people live, or in the commercial production, all need in metope or ground or ceiling etc., pre-install reinforcing bar suspenders such as anchor pole or bolt, be used for suspension or article are installed.For safe in utilization, often need the vertical tensile property of these suspenders of test.The device of the vertical tension pressure of existing test suspender; Need to change different force cells according to the specification of suspension member, for test process is made troubles, and in the test process; Because the deviation of directivity of used external force during pressurization; Or the inclination of suspender cause with device for measuring force in the sensor disalignment, thereby cause the test result out of true, therefore buried potential safety hazard for the follow-up use of suspender.
The utility model content
The utility model technical matters to be solved be to provide a kind of can be general under different suspension member sizes; And when overcoming dynamometry since the test error that the inclination of external force deviation or suspender causes have a device for measuring force of locating steering ball; Make test more convenient; The result is more accurate, guarantees safe in utilization side by side.
For solving the problems of the technologies described above; The utility model provides a kind of device for measuring force of locating steering ball that has; The tension of anchor pole or bolt in the test base; Comprise annular pressure sensor, surface bearing, compressive sleeve from bottom to top in regular turn, be enclosed within on anchor pole to be measured or the bolt that compressive sleeve external diameter and surface bearing internal diameter are less than the internal diameter of annular pressure sensor; Press on the pressure transducer by compressive sleeve; Wherein: above or below described pressure transducer, be provided with the annular ball seat of band screw vent and the location steering ball mechanism that annular bowl-shape hemisphere is formed, described annular ball seat and annular bowl-shape hemisphere are smoothly chimeric, and the annular bowl-shape hemisphere planar ends of pressure transducer engages with pressure transducer.
During use, select the specification of required compressive sleeve for use according to the test specimen specification, compressive sleeve passes surface bearing, need not more emat sensor and location steering ball mechanism, reaches laborsaving and general convenience; Location steering ball mechanism can be installed in pressure transducer above or below use.During test; Because ball seat and bowl-shape hemisphere in the steering ball of location are smoothly chimeric; Therefore bowl-shape hemisphere can be free to slide in ball seat, even when the external force direction that applies has deviation or suspender inclination to be tested during dynamometry, pressure transducer can be free to slide in the ball impression of ball seat with bowl-shape hemisphere; And bowl-shape hemispheroidal plane remains and the pressure transducer positive engagement; Guarantee that pressure transducer is stressed evenly, thereby both protected pressure transducer, guaranteed the accuracy of test result again.
On the such scheme basis, described annular ball seat is provided with round concave spherical surface, and the bowl-shape hemispheroidal sphere of described annular is smoothly chimeric with the circle concave spherical surface.
In order to protect pressure transducer, and prevent the influence to the utility model such as dust when operating at the scene, be covered with protective cover at sleeve, this protective cover covers on outside compressive sleeve, surface bearing, the annular pressure sensor in regular turn.
On the such scheme basis, described pressure cuffs jacket casing is made up of sleeve and top nut, and sleeve passes location protective cover inner via hole pressure transducer is exerted pressure.
On the such scheme basis, the bowl-shape hemispheroidal planar ends of described annular is provided with annular slot, and pressure transducer is embedded in the annular slot, and pressure transducer is fixed in the bowl-shape hemispheroidal circular draw-in groove all the time, more compact structure, firm.
The pressure transducer of the utility model is stressed evenly, has prolonged the serviceable life of pressure transducer, and has guaranteed the accuracy of test result.

Embodiment
The utility model is located shown in the steering ball mechanism structure synoptic diagram for structural representation and Fig. 2 of location steering ball like Fig. 1; Be a kind of device for measuring force of locating steering ball that has; Comprise compressive sleeve 1, location protective cover 2, surface bearing 3, pressure transducer 4, location steering ball mechanism 5, compressive sleeve 1 is made up of nut that is fixed together 11 and sleeve 12; Location steering ball mechanism 5 is as shown in Figure 2; Form with annular ball seat 52 by the bowl-shape hemisphere 51 of annular; Ball seat 52 inside are the concave spherical surface shape, and there is round tube hole the upper end, and there is cylindrical hole at the center of bowl-shape hemisphere 51; Lower surface has concentric circular draw-in groove 511, and bowl-shape hemisphere 51 is smoothly chimeric with ball seat 52.
In actual dynamometry process, compressive sleeve 1 is slightly less than surface bearing 3 with location protective cover 2 diameters, prevents that surface bearing 3 from sliding because of the external force deviation produces, and damages pressure transducer 4 and influence test accuracy; The effect of surface bearing 3 can turn compressive sleeve 1 when being to make test with less strength, reach the laborsaving purpose of test; Location steering ball 5 can be installed in pressure transducer 4 above or below use, and no matter be installed on above or below the pressure transducer 4, the draw-in groove 511 of annular bowl-shape hemisphere 51 all the time with pressure transducer 4 tablings.Because the ball seat 52 in the steering ball 5 of location is smoothly chimeric with bowl-shape hemisphere 51, bowl-shape hemisphere 51 can be free to slide for 52 li at ball seat.During dynamometry; Turn nut 11 with spanner and exert pressure, even the direction of exerting pressure has deviation or tested suspender that inclination is arranged, bowl-shape hemisphere 51 can slide along with the external force deviation produces; Remain circular draw-in groove 511 and pressure transducer 4 positive contacts; All the time make pressure transducer 4 stressed even, thereby both protected pressure transducer, guaranteed the accuracy of test result again.
