Embodiment
As depicted in figs. 1 and 2, a kind of Portable multi-head concrete bouncing back instrument, including telescopic shell 1 and some reisilometer lists
Body 2.The one end open of telescopic shell 1, inside is used to the reisilometer monomer 2 is fixedly installed provided with some single cavities 3.It is logical
Integrated multiple reisilometer monomers 2 in the telescopic shell 1 are crossed, the synchronous detection of multi-measuring point are realized, so as to reduce detection
Workload, raising detection efficiency.
The quantity of the reisilometer monomer 2 is 4 multiple.Required according to existing concrete reisilometer operational procedure, survey area
Interior rule lays 16 measuring points.Under regular situation, area is surveyed from square, often 4 measuring points are all provided with row, each column.The resilience
Monomer 2 is laid according to measuring point.Consider the lower pressure needed for attack, the quantity of reisilometer monomer 2 preferably selects 4.
The telescopic shell 1 is by fixed shell 4, dynamic housing 5 and connects the fixed shell 4 and the bottom of dynamic housing 5
Flexible extension spring 6 is constituted.The inwall of fixed shell 4 is provided with the chute that the gib block 51 being provided with the dynamic outer wall of housing 5 matches
41.The dynamic housing 5 vertical telescopic in the fixed shell 4 is slided.The top surface levelness of dynamic housing 5 is higher.Due to
The topside area of dynamic housing 5 is noticeably greater than the top cross-section area of elastic stem 22 of the reisilometer monomer 2, thus is conducive to protecting
The axis trend of the reisilometer monomer 2 is demonstrate,proved, so as to improve accuracy of detection.
The reisilometer monomer 2 mainly includes central guide rod 21, elastic stem 22, elastic tension spring 23, elastic hammer 24, hook
25th, zeroing screw 26 and sensor 27.The central guide rod 21 is arranged at the axis of the single cavities 3, the extension
Hook 25 and the zeroing screw 26 are arranged at the blind end bottom of fixed shell 4.The construction of reisilometer monomer 2 and existing coagulation
Native reisilometer structure is similar, and the shell structure of existing concrete reisilometer is replaced using the single cavities 3.For the ease of improving
Detection efficiency, then can use electronic/digital formula.
The sensor 27 can select velocity sensor or range sensor, and with being arranged at the outer wall of fixed shell 4
The data storage device 7 at place is connected.The data storage device 7 uses integrated chip, can simultaneously store, handle multi-group data.
The spacing of reisilometer monomer 2 is not less than 20mm.The open top width of dynamic housing 5 is not less than 20mm.According to
Existing concrete reisilometer operational procedure requires the spacing set, to ensure to detect structure accuracy.
Illustrate that the utility model embodiment is as follows in conjunction with the embodiments：
In embodiment, horizontal layout has 4 reisilometer monomers 2 in the telescopic shell 1, and 4 can be once detected simultaneously
Individual measuring point.
When surveying area's layout, it is only necessary to determine the base level line in square survey area.
S1：The bottom two ends of fixed shell 4 described in hands grasping, make the plan vertical of dynamic housing 5 pressure at inspection area.Push
The fixed shell 4, shrinks the dynamic housing 4, until each elastic stem 22 is contacted with surveying area surface.Both hands thumb gently presses institute
The bottom of fixed shell 4 is stated, makes each hook 25 out of stock.
S2：Slowly lift the fixed shell 5, the elastic stem 22 and the dynamic housing 5 is stretched out simultaneously, it is static after, two
Person's top horizontal.Now, the hook 25 hangs up the elastic hammer 24, the record start data of sensor 27, and reaches institute
State storage in data storage device 7.
S3：The top upper limb alignment base level line of dynamic housing 5 is adjusted, lower edge, which is located at, to be surveyed in area.Slowly push again
The fixed shell 4, shrinks the dynamic housing 5 and the elastic stem 22.After the elastic stem 22 is depressed sufficiently, make the hook
25 break off relations with the elastic hammer 24.It is elastic hammer 24 along the central guide rod 21 under the pulling force effect of elastic tension spring 23
Hit the elastic stem 22.Collision makes the stress of elastic hammer 24 to jump, the now end of record data of sensor 27, and passing
Stored in the data storage device 7.
Completion is once tested.
S4：Repeat S2 operations.The telescopic shell 1 is moved down, the top upper limb of dynamic housing 5 is down to dynamic shell during S3
The top lower edge of body 5.S3 is repeated, second is completed and tests.
Being repeated two more times S4 can complete to survey the detection operation of 16 measuring points in area.
