experiment example

[0022] Perform a performance test on a certain type of hob.

[0023] 1. Test preparation

[0024] Check whether each connecting bolt of the test platform is loose and whether each control system is working normally, and if there is any abnormality, take appropriate measures. Make sure the main power is off.

[0025] 2. Test process

[0026] running test running test

[0027] 1) Use the universal fixture and the top to fix the cutter shaft firmly, and adjust the cutter ring clamping device to a suitable height to clamp the cutter ring;

[0028] 2) Start the running-in power device of the hob and run-in for a certain period of time. If the operation is stable and there is no abnormal noise, the cutter bearing is qualified.

[0029] 2. Hob air tightness test

[0030] 1) Fix the tested hob on the universal fixture on the table:

[0031] 2) Connect the quick interface of the air circuit on the table and the interface of the tool with a hose, turn on the air source, adjust to ...

Abstract

Hob comprehensive performance detection testing platform is a testing platform to carry out a comprehensive detection for critical performance of a tunnel boring machine hob and consists of a hob running-in test equipment, an air tightness test equipment and a rolling torque testing device. The hob comprehensive performance detection testing platform has advantages that an integrated design is carried out for the hob running-in test equipment, the air tightness test equipment and the rolling torque testing device of the hob, the three devices are in the same platform and all detection devices are designed to be adjustable. According to the hob comprehensive performance testing platform, the integrated detection for bearings, sealing devices and assembly quality of the hob can be achieved to guarantee reliability of critical performance of the hob and smooth tunneling of the tunnel boring machine.

Description

technical field [0001] The invention relates to the field of basic research of shield tunneling technology, and specifically designs a test platform for comprehensive performance detection of hob cutters of tunnel boring machines. Background technique [0002] With the development of science and technology, tunnel boring machines are widely used in underground engineering and tunneling operations. In the tunnel boring machine construction, although there are various knives distributed on the cutter head, the hob mainly relies on the hob to roll, crush and cut rock, soil and sand. Since the hob bears huge load and impact, severe friction and high temperature, the connection performance and sealing performance of each part are easily damaged. According to engineering examples, with the increase in hob maintenance and tool change times, the phenomenon of tool bolts loosening, falling off, breaking and even tool dropping is becoming more and more serious. The performance of th...
