Embodiment Construction

[0015] Such as figure 1 and figure 2 As shown, the rock cutting tool cutting test device includes a material box moving device 1, a material box rotating device 2, a tool device 3, a pressing cylinder device 4, a tool moving device 5, an overall frame 6 and a tool locking device 7. The integral frame 6 is connected by four tension rods 601 with prestress to connect the upper beam 602 , the lower beam 603 and the middle beam 604 . The overall frame 6 is rigidly connected with the material box moving device 1, and the material box moving device 1 is connected with the foundation. So that the whole is stable and the equipment is rigid. Said bin moving device 1 at least includes a base 101 , a guide rail 102 , a workbench 103 , and a hydraulic cylinder 104 . The working table 103 is pushed by the hydraulic cylinder 104, and the container turning device 2 is moved to the working area for work. After the rock breaking is completed, the hydraulic cylinder 104 pulls the material ...

Abstract

The invention belongs to the field of hardware tools or tunnel boring machines, and in particular to a cutting test method for a rock-cutting tool. The cutting test method for the rock-cutting tool is characterized in that: a cutting test device for the rock-cutting tool comprises a storage box moving device, a storage box turning device, a cutting tool device, a screw-down oil cylinder device, a cutting tool moving device, a whole frame and a cutting tool locking device; the whole frame is formed by connecting an upper crossbeam, a lower crossbeam and a middle crossbeam by four prestressed pull rods; the whole frame is in rigid connection with the storage box moving device which is connected with a foundation; the storage box moving device at least comprises a pedestal, a guide rail, an operating platform and a hydraulic cylinder; the storage box turning device is arranged on the operating platform which is fixed on the guide rail on the pedestal; and the storage box turning device is moved to a working area to work by pushing the operating platform by the hydraulic cylinder. The cutting test method for the rock-cutting tool can really simulate the actual working condition of a tunnel boring machine (TBM) so as to systematically analyze the rock breaking and wearing processes of the rock-cutting tool.

Description

technical field [0001] The invention belongs to the field of hardware tools or shield machines, especially the field of rock cutting tools. Specifically, it is a cutting test method for rock cutting tools, which is mainly used for important engineering special equipment for urban subway construction, road and tunnel construction, etc. Background technique [0002] Shield machine (TBM) is an important engineering special equipment mainly used in urban subway construction, road and tunnel construction, etc. With the vigorous development of road traffic construction in our country, the shield machine will play a greater role and have a broad space for use. But at present, only a few countries in the world, such as Europe, America and Japan, have the ability to master the research and development and production of this equipment. The shield machines used in my country mainly rely on foreign imports, and the equipment system, cost, use, and maintenance costs are extremely high. ...
