specific Embodiment 2

[0090] The specific embodiment 2 of the roadheader provided by the present invention is mainly different from the embodiment 1 in that: in the embodiment 1, the damper is fixed in the corresponding opening cavity by welding. In this embodiment, threaded holes are formed on the side walls of the damper, and fixing holes corresponding to the threaded holes on the damper are formed on the ribs of the corresponding openings. Screws fix the dampers in the corresponding openings.

specific Embodiment 3

[0091] The specific embodiment 3 of the roadheader provided by the present invention is mainly different from the embodiment 1 in that: in the embodiment 1, the sealing cover is fixed in the corresponding particle filling hole by screws. In this embodiment, the sealing cover is a screw plug, and the corresponding particle filling hole is a threaded hole.

[0092] The specific embodiment 4 of the roadheader provided by the present invention is mainly different from the embodiment 1 in that: in the embodiment 1, the volume of the damping particles in the box accounts for 70%-90% of the cavity of the box. In this embodiment, the volume of the damping particles in the box accounts for less than 70% of the cavity of the box, such as 65%.

specific Embodiment 5

[0093] The specific embodiment 5 of the roadheader provided by the present invention is mainly different from the embodiment 1 in that: in the embodiment 1, the mass ratio of damping particles of different sizes in the damper ranges from 1:1 to 1:1.5. In this embodiment, the mass ratio of the damping particles of different sizes in the damper is greater than 1:1 to 1:1.5, and is 1:1 to 1:1.6. Of course, in other embodiments, the damping particles of different sizes in the damper The mass ratio of the particles can also range from other ranges of values ​​greater than 1:1 to 1:1.5.

[0094] The embodiment of the roadheader cutter head provided by the present invention:

[0095]The structure and working principle of the cutter head of the roadheader in the present invention are the same as those of the cutter head of the above-mentioned roadheader, and will not be repeated here.

Abstract

The invention belongs to the field of tunnel excavation equipment, and particularly relates to a heading machine cutterhead and a heading machine. The heading machine cutterhead comprises a cutterhead panel and hobs installed on the cutterhead panel, the cutterhead panel comprises a front panel, hob installation holes are formed in the front panel, rib plates are fixed to the rear panel face of the front panel, and the hob installation holes are formed in the rib plates; the rib plate is matched with the front panel to form different open cavities with backward openings on the rear side of the front panel, the cutterhead of the heading machine further comprises a damper installed in at least part of the open cavities, the damper comprises a closed box body and damping particles filled in the box body, the shape of the box body is matched with that of the open cavities, and the damping particles are arranged in the box body. A box body of the damper is fixedly connected with a rib plate, the front side wall of the box body is attached to a front panel, the rear side wall of the box body forms a sealing plate for sealing a cavity opening of a corresponding opening cavity and forms a rear panel of a corresponding area of a cutterhead panel at the same time, the side wall of the box body is connected with the rib plate, vibration reduction is achieved through the damper, and meanwhile the damper enhances the connecting strength of the rib plate. And the structural strength of the cutterhead is further ensured.

Description

technical field [0001] The invention belongs to the field of tunnel excavation equipment, in particular to a boring machine cutter head and a boring machine. Background technique [0002] As a kind of underground engineering equipment with high degree of mechanization, fast driving efficiency and safe construction, hard rock roadheaders are widely used in underground space development. During the specific work, the cutter head of the hard rock roadheader rotates under the driving of the main drive and squeezes each other through the hob on the cutter head panel and the rock surface, so that the rock is broken and fallen off, and the excavation of the hard rock formation is realized. [0003] Compared with the excavation of soft soil strata, the impact load generated in the rock breaking process of the hard rock roadheader will cause the cutter head on which the hob is installed to vibrate violently, and the instantaneous large load impact may cause serious deformation of the...
