Description
Technical field
The utility model relates to a kind of pick-up unit that is used to detect the concrete sample inherent vice, is applicable to the detection of the test specimen of various common sizes and concrete grade.
Background technology
Detection method to the concrete sample inherent vice mainly contains at present: ultrasonic imaging Non-Destructive Testing, infrared imaging detection, geological radar detection etc.But these detection methods all are the surveys line that adopt hand-held instrument, finish along the test specimen surface to be measured.The speed that is difficult to controlled motion speed in the measuring process causes in the post analysis processing procedure extremely inaccurately to defect location, and detection efficiency is also very slow.The traditional concrete checkout equipment can only carry out analyzing and processing and artificial interpretation to the one-dimensional signal that is received, inefficiency, and reliability is relatively poor.In addition because the composite material that concrete is made up of cement, sand, thick bone loose material; Simultaneously owing to testing environment in the bridge detection is complicated; Influence factor is many; Directly receive the signal and obtain also to have sizable difficulty and uncertainty the general suitable working experience of dependence device operator that needs relatively definitely about the description of concrete internal soundness from one dimension.This has become serious restriction concrete Ultrasonic detection means and has popularized and the one of the main reasons that develops.
Summary of the invention
The technical matters that the utility model solved is exactly: a kind of test experience device of concrete sample inherent vice is provided, and this device can load multiple detecting instrument test specimen is detected quickly and accurately.
The utility model solves the technical scheme that its technical matters adopted: a kind of pick-up unit that is used to detect the concrete sample inherent vice; Comprise the displacement platform; Described displacement platform comprises displacement playscript with stage directions body, the slide block that is provided with the detecting instrument fixed orifice, screw rod, servomotor and displacement controller; Described screw rod is arranged at also can be around the axis rotation with driving sliding block in the displacement playscript with stage directions body; Described slide block is arranged on the displacement playscript with stage directions body and connecting screw rod, and described servomotor connecting screw rod is with the drive screw rotation, and displacement controller is electrically connected to the control end of servomotor.
Described a kind of pick-up unit that is used to detect the concrete sample inherent vice also comprises fixed support, and described displacement platform is fixed on the fixed support.
Described a kind of pick-up unit that is used to detect the concrete sample inherent vice, described support bracket fastened bottom is equipped with pulley.
The technique effect of the utility model is that various detecting instruments are fixed on the slide block through jig, by the displacement mode and the speed of displacement controller control slide block, according to the detection needs test specimen is fixed a point to detect or continuous area detection.The detection efficiency and the precision of the utility model are higher, and economical rationality can be carried multiple detecting instrument, are convenient to implement, and have stronger application value.
Below in conjunction with accompanying drawing the utility model is described further.
