Technical field
The invention patent relates to concrete strength inspection Instrument technology field, more particularly to one kind are novel based on annular elastomeric The concrete bouncing back instrument of spring.
Technical background
Concrete bouncing back instrument is strong for detecting common buildings component, bridge and various concrete components (plate, beam, column, gantry) The instrument of degree.But existing concrete reisilometer is hand-held by operator, applies the type excited after external force, spring energy-storage manually Formula, there are inconveniences.
In the existing patent about concrete bouncing back instrument, most of is in the premise for not changing reisilometer spring energy-storage construction Under, it is aided with external support facility, improves the precision and operability of measurement, but there is no shakinesses when improving rebound for such measure Determine factor, and often size is bigger than normal for external aids, it is inconvenient to be unfavorable for realizing.
Summary of the invention
Present invention aim to overcome drawbacks described above, a kind of concrete bouncing back instrument based on ring spring is provided, is adopted Use ring spring as energy storage member, mutually converting for curvilinear motion and linear motion can substantially reduce instrument axial dimension.
To achieve the goals above, the concrete bouncing back instrument based on ring spring designed by the present invention, including elastic stem, Casing is characterized in that further include connecting rod, pointer, notched ring spring, described connecting rod one end and annular elastomeric Spring notch side is hinged, and the other end and elastic stem one end are hinged, and the elastic stem is arranged in Normal Constraint device, the connection Bar, pointer and notched ring spring are arranged in casing, and the opening mobile for elastic stem is provided on the casing;Institute State the limit restraint device for also setting up on casing and limiting annular spring contraction position;The pointer is directed toward ring from ring spring center Shape spring and connecting rod hinged place, the corresponding dial of the pointer are arranged on the hollow out window of casing.
Further, the dial is circular ring shape, is parallel to ring spring, is located above ring spring, the casing Hollow out window is the transparent sight hole for being provided with transparent cap.Convenient for observing the reading of pointer, make whole device in closed sky In, improve precision and the service life of whole device.
It further, further include being set inside the metal framework for constraining annular SPRING METHOD OF STONE to mobile metal framework It is equipped with the sliding slot moved radially for ring spring, guarantees that ring spring loses without strain energy of distortion.
Further, it is provided with the zeroing screw for adjusting pointer direction on the ring spring, guarantees that pointer is each Dial zero point is all pointed to before measurement, avoids initial error.
Further, the ring spring notch side is provided with shock absorbing resilient gasket, energy loss when avoiding springing back.
Further, cooperate normal direction restraint device to be provided with axially directed piece of sliding block on the elastic stem, guarantee elastic stem The vertical excitation measured every time.
Further, the limit restraint device includes position-limitting pin and is provided in Normal Constraint device, casing and bullet Hit the corresponding limit pin hole of bar side wall.
The present invention has the advantages that
Using ring spring as energy storage member, curvilinear motion and linear motion are mutually converted, compared with traditional design, Instrument axial dimension can substantially be reduced.And ring spring has hysteresis effect, can provide strength and buffer, meet narrow It is used under bulk restrictive condition, improves the operability of instrument.
Detailed description of the invention
Fig. 1 is the reisilometer block schematic illustration of the present application patent.
Fig. 2 is the ring spring and double link schematic device of the present application patent.
Fig. 3 is the attack rod guiding device and Normal Constraint device figure of the present application patent.
Fig. 4 is the ring spring block schematic illustration of the present application patent.
In figure, 1 casing, 2 dials, 3 transparent sight holes, 4 casing limit pin holes, 5 ring springs, 6 second shafts, 7 refer to Needle, 8, elastomeric pad, 9, first rotating shaft, 10 zeroing screws, 11 metal link rods, 12 elastic stems, 13 guide runners, 14 Normal Constraints Device, 15 limit pin holes, 16 metal frameworks.
Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments:
A kind of concrete based on ring spring as Figure 1-Figure 4 designed by the present invention, that the invention patent provides Reisilometer device, including casing 1, dial 2, ring spring 5, doubly-linked lever apparatus and Accessory Members.Casing 1 is provided with one above A reading pointer 7 is arranged in a casing limit pin hole 4,5 plane of ring spring.
Wherein, in practical applications, ring spring 5 is circular ring shape jaggy, and notch side has shock absorbing resilient gasket 8.
Wherein, in practical applications, the doubly-linked lever apparatus includes metal link rod 11, elastic stem 12 and shaft 9.Metal connects 11 one end of bar is hinged on 5 notch side of ring spring by first rotating shaft 9, and the other end passes through the second shaft 6 and elastic stem 12 1 End is hinged.Elastic stem 12 is equipped with Normal Constraint component 14, is additionally provided on elastic stem 12 and matches with Normal Constraint component 14 The axially directed piece of sliding block 13 closed;14 side wall of Normal Constraint component is provided with limit pin hole 15.Elastic stem 12 and chassis sidewall It is correspondingly arranged on limit pin hole, cooperation position-limitting pin realizes that the accumulation of energy to entire elastic stem limits, and pointer 7 is from ring spring 5 The heart is directed toward metal link rod end shaft 9.
Wherein, in practical applications, stating dial 2 is circular ring shape, is placed in right above ring spring 5 in parallel, 1 top of casing Transparent sight hole 3 is set.
Wherein, in practical applications, the 5 notch other side of ring spring is fixed.Remaining position is located in metal framework 16, gold Category frame 16, which is fixed on remaining position of casing annular spring, to be moved axially along spring, Normal Constraint.
Wherein, in practical applications, ring spring notch side is provided with the zeroing spiral shell for adjusting pointer direction Nail.When practical application, elastic stem 12 is compressed by external force, doubly-linked lever apparatus is driven to move, ring spring 5 is shunk.To annular elastomeric Spring 5 is contracted to required position, and limit pin hole 15 cooperates position-limitting pin to constrain elastic stem, i.e., carried out about to ring spring Beam.Spring constraint is removed by pulling out position-limitting pin, ring spring 5 stretches, by doubly-linked lever apparatus by the curve of ring spring 5 Conversion of motion is the linear motion of elastic stem 12.Elastic stem 12 starts to spring back after hitting surveyed concrete component, and the reading of pointer 7 is annular Spring 5 springs back center of circle angle value, obtains surveyed strength indexes of concrete by conversion.
Above example is only used to illustrate the technical scheme of the present invention and not to limit it, and those skilled in the art should manage Solution, technical solution of the present invention are modified or are replaced on an equal basis, without departing from the spirit and scope of the technical solution of the present invention, It should cover within the scope of the claims of the present invention.
