Abstract

The present invention discloses a test-bed for detecting measurement precision of a deflection-measuring system (4) of a continuous wall grab bucket machining device, including a control device (1), a power device (2) and a mobile device (3); the control device (1) controls the power device (2), so that the power device (2) drives the mobile device (3) to move according to a presetting motion state signal; the deflection-measuring system (4) detects a motion state of the mobile device (3) and transmits obtained detection signals to the control device (1); the control device (1) receives the detection signal and compares the detection signal with the motion state signal to obtain the measurement precision of the deflection-measuring system (4). the invention also discloses a test method for detecting the measurement precision of the deflection-measuring system (4) of the continuous wall grab bucket machining device. By means of the test-bed and the test method of the invention, it is capable of detecting the precision of the deflection-measuring system of the continuous wall grab bucket conveniently and accurately, and finding out reasons of affecting the system deflection-measuring precision.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a test bench for detecting the deviation measuring system of a continuous wall grab. Background technique [0002] Diaphragm wall grab is the main equipment for grooving in engineering construction, and its grooving accuracy directly affects the quality of diaphragm wall grab, while the grooving accuracy of diaphragm wall grab is mainly determined by the verticality of its working device and the composition of the grab. The depth of the groove is determined. Therefore, ensuring the verticality of the working device and the depth of the groove of the grab can directly guarantee the quality of the continuous wall grab. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical diaphragm wall grab in the prior art. [0004] The underground diaphragm wall grab mainly includes a mast 12 and a working device 14. The bottom of the mas...
