Description

Technical Field

[0001] The utility model relates to the field of shield machine cutters, in particular to a shield machine cutter hardness detection device. Background Art

[0002] The shield machine is a modern large-scale mechanical equipment used for tunnel construction. It can perform soil excavation, transportation and lining operations underground. This equipment is usually composed of main parts such as cutter head, shield shell, propulsion system, excavation system, lining system, etc. As an important engineering machinery for underground tunnel excavation, the wear condition of the cutter of the shield machine is directly related to the construction efficiency and safety. Under complex geological conditions, the hardness test of the cutter is particularly important. A shield machine cutter hardness test device is used to fix the cutter sample to ensure that the sample does not move during the test, and is used to apply a certain load to the cutter sample for hardness testing.

[0003] After searching, a utility model is disclosed in the announcement number: CN220271070U. The utility model discloses a tool hardness detection device, including a sliding base, a limiting groove is arranged in the middle of the sliding base, an inner sliding block is slidably installed in the limiting groove, an internal threaded tube is rotatably installed in the middle of the inner sliding block, and several groups of test blocks are inserted and placed in the inner sliding block, and the strength of the several groups of test blocks is strengthened sequentially. The inclined plate is used in conjunction with the leakage groove opened inside the limit groove, so that the cutting waste liquid and waste chips can be sent out more quickly to ensure the stability of the movement of the inner slider. Since the strength of the test blocks inserted inside the inner slider increases successively, the cutting tool body can be subjected to different levels of strength tests when the inner slider moves until the cutting tool body reaches the maximum strength and collapses. The strength test of the cutting tool body can be completed more accurately. The protective cover plate protects the cutting tool body and can avoid external damage to the greatest extent when the cutting tool body collapses. The application cannot perform multi-directional hardness testing on the tool and there is no clamping and positioning assembly for clamping the tool. It is easy to shake when testing the hardness, which affects the detection effect. Since the hardness of different positions of the tool cannot be detected, the practicality of the device is also limited. Utility Model Content
