Abstract
The utility model discloses a civil engineering hollow drum detection device, comprising a base; a signal processor internally provided with a signal processing circuit is arranged on the base; moving wheels are arranged at four corners of the bottom surface of the base; a connection rod is arranged at the side surface of the base; the rear end of the connection rod is hinged to the base; the front end of the connection rod is provided with a detection head; a microphone for collecting sound is arranged at the connection rod close to the detection head; the microphone is connected with the signal processing circuit; an elastic member for attaching the detecting head to a wall surface is arranged between the connection rod and the side surface of the base. In the detection process of the civil engineering hollow drum detection device, the detection head is enabled to always slide by adhering to the wall surface due to the action of the elastic member, the phenomenon of the instable contact when the detection head, held by a detection person, slides at the wall surface is prevented, so the accuracy of the detection result is ensured; the sliding of the detection head on the wall surface is realized by using moving the base, so the operation is convenient.
Description
Technical field
The utility model relates to a kind of civil engineering hollowing pick-up unit.
Background technology
In engineering civil engineering quality, the hollowing phenomenon of body of wall will badly influence intensity, the later stage decoration quality in house and use in the future, and therefore, in the time of Building Inspector, it is an important quality detecting index that hollowing detects.Conventionally the method that metope is manually knocked in employing in the past, according to the difference of sounding after knocking, judges hollowing situation, and therefore human factor is more, and accuracy rate is difficult to guarantee.Therefore also just there is electronic type detector, by the detecting head acoustical signal that sliding friction produces on metope, through signal processor processes, according to the analysis such as sound frequency, pulse width, judged the hollowing situation of body of wall.But this electronic type detector, conventionally adopts hand-held to hold detection head and moves on metope, when mobile, can produce unavoidably detection head and contact the phenomenon of not being close to metope, bring error to testing result.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency of prior art, provide one can make detection head be close to metope, guarantee to detect data civil engineering hollowing pick-up unit accurately.
The utility model solves the technical scheme that its technical matters adopts: a kind of civil engineering hollowing pick-up unit, comprise base, described base is provided with the signal processor that is built-in with signal processing circuit, four jiaos of base end faces are arranged with movable pulley, base side is provided with connecting link, connecting link rear end and base are hinged, connecting link front end is provided with detection head, the connecting link of nearly detection head is provided with the microphone of collecting sound, microphone and signal processor connection, be provided with between connecting link and base side in the time detecting and guarantee that detection head is closely attached on the elastic component of metope.
Further, described connecting link end has reclinate bend, and detection head is located at the end of bend, and microphone is located on the bend of connecting link.
Specifically, described elastic component is Compress Spring, and base side is provided with pressing plate, is fixed with briquetting on connecting link, and Compress Spring is between pressing plate and briquetting.
The beneficial effects of the utility model are: the utility model is in testing process, rely on Compress Spring effect, guarantee detection head be close to all the time metope slide, prevented that testing staff held detection head in the past contacts unsettled phenomenon in the time that metope slides, improve the accuracy of testing result, utilize the mobile detection head that drives of base to slide on metope, operation is also convenient simultaneously.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of civil engineering hollowing pick-up unit as shown in Figure 1, comprise base 1, described base 1 is provided with the signal processor 2 that is built-in with signal processing circuit, and four jiaos of base 1 bottom surfaces are arranged with movable pulley 3, base 1 side is provided with connecting link 4, and connecting link 4 rear ends and base 1 are hinged.
Described connecting link 4 ends have reclinate bend 41, the end of bend 41 is provided with detection head 5, bend 41 is provided with the microphone 6 of collecting sound, microphone 6 and signal processor 2 connections, between connecting link 4 and base 1 side, be provided with in the time detecting and guarantee that detection head 5 is closely attached on the Compress Spring 7 of metope, base 1 side is provided with pressing plate 8, is fixed with briquetting 9 on connecting link 4, and Compress Spring 7 is between pressing plate 8 and briquetting 9.
When the utility model uses, rely on Compress Spring 7 to act on, make detection head 5 be close to metope, testing staff moves pedestal 1, and detection head 5 slides on metope, in sliding process, there is friction and produce voice signal in detection head 5, voice signal is collected by microphone 6, is sent to signal processor 2 with metope, signal processor 2, according to the sound frequency height of collecting, is judged the hollowing situation of metope.Due in testing process, rely on Compress Spring 7 to act on, making detection head 5 be close to all the time metope slides, therefore prevented that testing staff held detection head 5 in the past contacts unsettled phenomenon in the time that metope slides, guarantee the accuracy of testing result, utilize base 1 to move simultaneously and drive detection head 5 to slide on metope, operation is also convenient.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to claim scope.
