Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 3, the invention comprises a cutter disc 10, a power system 20 and a shield body 30, wherein the shield body 30 comprises a plurality of shield body blocks 305, a telescopic frame 301 and a hydraulic system 303, the adjacent shield body blocks 305 are movably connected through the hydraulic system 303, the telescopic frame 301 is fixed on the shield body 30, and the cutter disc 10 and the power system 20 are arranged on the telescopic frame 301.
The shield body block 305 is provided with a slide plate 306 on one side and a slide groove 307 on the other side, the slide plate 306 is matched with the slide groove 307, and the slide plate 306 between adjacent shield body blocks 305 is connected with the slide groove 307 to form the shield body 30. The distance between the shield blocks 305 is adjusted by the relative sliding of the sliding plate 306 and the sliding groove 307, so that the size of the shield 30 is adjusted. The change of the cross section size of the shield body 30 is realized through the extension and retraction of the shield body extension and retraction hydraulic system 303 and the relative movement between the sliding plate 306 and the sliding groove 307, so that the switching of the cross section area size within a certain range is realized.
A foldable shield shell 302 is further arranged between the adjacent shield blocks 305, and the foldable shield shell 302 is arranged on the outer side of the joint of the sliding plate 306 and the sliding groove 307. The connection part of the sliding plate 306 and the sliding groove 307 is protected and dustproof.
The telescopic frame 301 is fixed on one end on the shield block 305 and the other end on the cutter head 10 or the power system 20. The expansion and contraction of the hydraulic cylinders of the hydraulic system 303 drive the expansion or contraction of the distance between the shield blocks, so that the shield can be changed, and the expansion and contraction of the expansion bracket are driven. The expansion bracket 301 is a rod, and the expansion bracket 301 and the power system 20 are always kept at the center of the cross section of the shield body along with the change of the size of the cross section of the shield body, so that the adjustment of the size of the cross section of the shield body has no influence on the cutting cutterhead 10 and the power system 20, and the expansion bracket and the power system are mutually independent and can be adjusted according to production requirements.
