Problems solved by technology

[0003] However, the current laboratory devices used to fix the resistance strain extensometer achieve unsatisfactory results. During the experiment, the simple combination of spring and rubber band is used to fix the extensometer. It is easy to displace or even fall off, which seriously affects the accuracy of the experimental results and does not meet the experimental requirements

Abstract

The invention belongs to the field of strain extensometer fixation and specifically discloses a fixing device of a resistance strain extensometer. The fixing device comprises a support plate, a strainmeter connection board, a walking frame, walking wheels, a walking frame fixing mechanism and a support plate fixing mechanism. The support plate is connected to the support plate fixing mechanism. The support plate is provided with a guide channel used for linear motion of the walking wheels. The walking wheels are positioned inside the guide channel. The walking frame is arranged on the walkingwheels. The walking frame is provided with the strain meter connection board. The walking frame is fixed with the support plate through the walking frame fixing mechanism. According to the fixing device, a strain extensometer can be fixed on the walking frame through the strain meter connection board; as the walking wheels are arranged below the walking frame and walking wheels can move along a straight line, the strain extensometer is brought to an appropriate position; and the walking frame fixing mechanism fixes the walking frame and the support plate after the walking wheels move to an appropriate position, and the support plate is fixed by the support plate fixing mechanism. Thus, stability of the whole fixing device is ensured.

Description

technical field [0001] The invention belongs to the field of fixing strain extensometers, in particular to a fixing device for resistance strain extensometers and an application thereof. Background technique [0002] Under laboratory conditions, in order to obtain the change of elastic modulus of the specimen after experiencing different times of freeze-thaw cycles, a universal testing machine is used to conduct pressure experiments on test blocks of different sizes, and the change of elastic modulus is further obtained through the stress-strain relationship Condition. [0003] However, the current laboratory devices used to fix the resistance strain extensometer achieve unsatisfactory results. During the experiment, the simple combination of spring and rubber band is used to fix the extensometer. It is easy to displace or even fall off, which seriously affects the accuracy of the experimental results and does not meet the experimental requirements. Contents of the invent...
