Detailed description of the invention
The front view of the facing cutter protective cover that Fig. 1 provides for the embodiment of the present invention, the left view of the facing cutter protective cover that Fig. 2 provides for the embodiment of the present invention, Fig. 3 is the explosive view of Fig. 2.As shown in Figure 1 to Figure 3, the facing cutter protective cover that the present embodiment provides comprises: back cover 1 and front shroud, and front shroud comprises front shroud upper cover plate 21, front shroud lower cover 22 and access panel 23.Wherein, front shroud upper cover plate 21 and front shroud lower cover 22 are all spirally connected with back cover 1, and front shroud upper cover plate 21 and front shroud lower cover 22 are spirally connected.The side of access panel 23 and front shroud upper cover plate 21 pivot joint, opposite side and back cover 1 pin joint.
Front shroud adopts split-type structural, be made up of front shroud upper cover plate 21, front shroud lower cover 22 and access panel 23, shape as shown in Figure 1, wherein, the curved edge of front shroud upper cover plate 21 is connected with back cover 1 by bolt, the curved edge of front shroud lower cover 22 is also connected with back cover 1 by bolt, in the edge that front shroud upper cover plate 21 docks with front shroud lower cover 22, is connected by front shroud upper cover plate 21 by bolt with front shroud lower cover 22.
Access panel 23 adopts shape as shown in Figure 1, one side and front shroud upper cover plate 21 pivot joint, and access panel 23 can be rotated relative to front shroud upper cover plate 21, realizes access panel 23 to raise 180 °, hinge 24 specifically can be adopted to realize pivot joint.The arc-shaped edges of access panel 23 is connected with back cover 1 by pin, can refer to Fig. 4, Fig. 4 be in Fig. 1 A-A to sectional view.Spring catch 3 pairs of access panels 23 specifically can be adopted to be connected with back cover 1, in maintenance process, to extract spring catch 3, access panel 23 can be raised, to overhaul facing cutter.
When above-mentioned facing cutter protective cover is installed, first back cover 1 is fixed on facing cutter, again front shroud upper cover plate 21 is fixed on back cover 1, then front shroud lower cover 22 is fixedly connected with front shroud upper cover plate 21 with back cover 1 respectively, afterwards access panel 23 is connected with front shroud upper cover plate 21, finally by access panel 23 and back cover 1 pin joint, complete the installation of facing cutter protective cover.Because front shroud have employed split type structure, make the installation of facing cutter protective cover comparatively convenient.
When carrying out inspection and maintenance to facing cutter, first the latch structure connected between back cover 1 and access panel 23 being extracted, then access panel 23 being raised relative to front shroud upper cover plate 21, can facing cutter be exposed, be convenient to carry out inspection and maintenance to facing cutter.
