Problems solved by technology
[0004] However, because the coal mine roadway rock strata are mostly sedimentary rocks, the bottom plate is soft, and it is difficult to bear the weight of the conventional TBM main engine, and often the TBM will load the head or even jam the machine during construction.
In addition, the underground space of coal mines is limited, and the lifting capacity is generally insufficient. Especially in the construction of multiple roadways, the frequent transfer and disassembly of TBM takes up a lot of construction time, which is one of the main factors restricting the application of TBM in coal mine engineering.

The invention belongs to the technical field of tunnel boring machines, and particularly relates to a crawler walking open type TBM applied to coal mine rock roadway construction. The technical problem that in the coal mine tunnel construction process of a conventional TBM machine, main machine head loading and steering are not flexible can be solved. Comprising a main girder and a cutterhead, a main driving system and a belt conveyor are mounted on the main girder, and the main driving system is connected with the cutter head; the main driving system and the cutterhead are both mounted in the shield, and the shield is hinged to the temporary support through a temporary support oil cylinder; a main pushing oil cylinder is installed on the main girder, a cylinder rod of the main pushing oil cylinder is connected with one end of a supporting shoe, and the other end of the supporting shoe is connected with a saddle frame through a tight supporting oil cylinder. The saddle frame can slide back and forth on the main girder through the extension and retraction of the main push oil cylinder; the lower portion of the saddle frame is connected with a crawler walking mechanism, an anchor rod drilling machine is installed on the main girder, and the anchor rod drilling machine is used in cooperation with a temporary support and used for anchor rod supporting at the first time.
Description
technical field [0001] The invention belongs to the technical field of tunnel boring machines, and in particular relates to an open type TBM with crawler belts used in the construction of rock roadways in coal mines. Background technique [0002] In recent years, with the vigorous development of national infrastructure, the dependence on coal resources has gradually increased; for coal enterprises, higher requirements have been put forward, and there are many factors affecting coal excavation. Among them, roadway excavation construction technology is an important influencing factor, which directly determines the mining effect of coal enterprises, and also has a direct impact on the economic benefits of coal enterprises themselves. [0003] At present, coal mine roadway excavation has gradually developed from the traditional drilling and blasting + fully mechanized excavation construction to the direction of automation and intelligence, and the TBM technology for industrial t...
