A shield tool detection test device

Abstract

The invention discloses a shield cutting tool detection test device, which comprises a machine body. A vertical tube is arranged inside the machine body. A vertical bar is slidably connected to the inside of the vertical tube, and a fastening unit is arranged at the bottom of the vertical bar. The performance detection test device of the shield cutting tool, through the cooperation between the machine body, the pallet, the pulping barrel, the vertical cylinder, the vertical rod and the fastening unit, can pass through the tooth plate and the spur gear, the spiral groove and the protrusion at the bottom of the tooth plate The meshing connection makes the slider drive the block to slide centripetally or centrifugally when the tooth plate rotates, so that different types of shield tools can be installed to improve the efficiency of detection and testing. At the same time, through the sliding connection between the block and the block , the installed shield tool can be prevented from falling off to ensure the stability of detection. Through the sliding connection between the round rod and the cylinder, and the movable connection between the round rod and the tapered groove, the pulping barrel can be axially positioned and switched, and the lifting The reliability of detection data ensures the accuracy of detection.

Description

technical field [0001] The invention relates to the technical field of shield machine tool detection devices, in particular to a shield machine tool detection test device. Background technique [0002] At present, most of the tests on shield tool wear are based on rock abrasive tests, and steel needles and balls, which are the same material as the tool, are used instead of tools, which are different from the wear of real tools. In addition, the test of linear cutting machine and rotary cutting machine is also an indoor test method that is widely used at present, but the test situation that can be simulated is relatively simple, and it is different from the actual working conditions of shield cutters. In order to explore the influence of different shield tunneling parameters, different stratum conditions, different tool types and configurations, mud improvement materials and other factors on the tool wear, it is necessary to design a corresponding test device in consideration...
