Test-bed device for cutter of shield machine

The utility model relates to a test-bed device for a cutter of a shield machine. The thrust of the test-bed device reaches100 tons, and the driving torque of a cutter disk reaches 1000 KN.m. By adopting the test-bed device, various cutters of the shield machine can be installed on the test-bed device for realizing cutting simulation tests, the test-bed device can simulate a test-bed capable of providing provides various geological conditions, can accurately obtain the loading condition of each part of the cutter to carry out analysis and calculation and can ensure the manufacturing quality of various cutters of the shield machine and the adaptability of the cutters to various geological conditions, so that the appropriate cutters can be better chosen according to the geological conditions, and the design and manufacturing scheme can be optimized based on the geological characteristics. The test-bed device is composed of a boost hydraulic cylinder, a rack, a simulating rock-soil bin, a simulating shield machine cutter disk, a rotation support, a transition connecting disk, a bearing pedestal, a planetary speed reducer, a variable frequency motor, a transmission base, a signal system, a signal control system, an oil cylinder supporting boots, a guiding device, a gear sleeve coupling and a pin coupling. The test-bed device has a simple structure, is easy to manufacture, ensures the convenience and speediness of experiments and is labor-saving, time-saving and strength-saving; the wastage of the cutter of the shield machine is reduced, and the service life of the cutter is prolonged; and the work efficiency of the test-bed device is improved.
