Abstract

The utility model provides an elastic modulus measurement protection device, it mainly comprises exposed core, protection tube, electron extensometer, sample, exposed core, stress hole and rubber buffer, exposed core and centre gripping have the sample, upwards are provided with the protection tube sample week, and the protection tube is provided with the stress hole, and the rubber buffer sets up the clearance between protection tube and sample, and the electronics extensometer is installed in sample one side. The utility model discloses an at the protection tube that sample week upwards set up, it is effectual to the harm of electronics extensometer when having prevented sample tensile failure, guaranteed the person and equipment safety.

Description

A kind of elastic modulus measuring and protecting device
Technical field
The utility model relates to a kind of elastic modulus measuring and protecting device, belongs to detection experiment equipment technology field.
Background technology
Adopt electronic extensometer to detect elastic modulus during general steel strand tensile tests for prestressed concrete, and easily there is unexpected fracture in this sample in test drawing process, causes damaging electronic extensometer, even injures testing crew.And this kind of electronic extensometer protective device mainly utilizes based on the measuring principle of metal wire rod elastic modulus, the technological synthesis such as principle, the test method design of metal wire rod tension test, thus solve this technical barrier.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of elastic modulus measuring and protecting device, available protecting extensometer is not damaged in detection experiment process, the safety of warranty test personnel.
When detecting metal wire rod elastic modulus, a set of pre-designed protective device being installed, by the installation of device, sample not only can being protected surprisingly to rupture the device damage caused, simultaneously can also the handling safety of warranty test personnel.This device is by taking a set of tubular metal material, and sky is opened in employing, rubber clamp etc. of jumping a queue, and when can realize metal wire rod tension test, the detected parameters of neither shadow test, does not affect testing crew operation yet.
The utility model is primarily of bare terminal end, protection tube, electronic extensometer, sample, bare terminal end, stress hole and rubber plug composition; Bare terminal end and be clamped with sample, sample circumference is provided with protection tube, and protection tube is provided with stress hole, and rubber plug is arranged at the gap between protection tube and sample, and electronic extensometer is installed on sample side.Rubber plug, for clamping protection tube and sample, prevents protection tube from gliding.
When electronic extensometer is used for metal wire rod tension test detection elastic modulus under normal circumstances; because unexpected fracture easily appears in sample in tension test process; electronic extensometer is caused to damage; personnel even may be caused to injure; the protection tube of the utility model by arranging in sample circumference; infringement to electronic extensometer when effectively preventing sample tension failure, ensure that the person and device security.
The beneficial effects of the utility model:
1, this apparatus structure is simple, makes easily, easy to use.
2, available protecting extensometer is not damaged in testing process, ensure that the person and device security.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of elastic modulus measuring and protecting of the utility model device.
In figure: 1-bare terminal end, 2-protection tube, 3-electronic extensometer, 4-sample, 5-bare terminal end, 6-stress hole, 7-rubber plug.
Embodiment
Below in conjunction with accompanying drawing, a kind of elastic modulus measuring and protecting of the utility model device is described in further detail:
In figure: it forms primarily of bare terminal end 1, protection tube 2, electronic extensometer 3, sample 4, bare terminal end 5, stress hole 6 and rubber plug 7; Bare terminal end 1 and 5 is clamped with sample 4, and sample 4 circumference is provided with protection tube 2, and protection tube 2 is provided with stress hole 6, and rubber plug 7 is arranged at the gap between protection tube 2 and sample 4, and electronic extensometer 3 is installed on sample 4 side.
Electronic extensometer 3 is for the detection to elastic modulus during metal wire rod tension test; and because unexpected fracture easily appears in sample in tension test process; electronic extensometer is caused to damage; personnel even may be caused to injure; the protection tube 2 of the utility model by arranging in sample 4 circumference; infringement to electronic extensometer 3 when effectively preventing sample 4 tension failure, ensure that the person and device security.
