Abstract
The utility model discloses an advance knife for a shield machine with a wear display function, comprising a knife body installed with a hard alloy body and a fixing shaft installed in a knife body shaft hole by means of interference fitting, wherein the knife body is provided with an inner cavity; the inner cavity is communicated to the upper end installed with the hard alloy body of the knife body from the lower end of the knife body; the inner cavity is connected with an oil transportation system; and the oil transportation system is provided with a pressure gage or a pressure sensor. Via the inner cavity disposed on the knife body and connected with the oil transportation system, oil with a certain pressure is filled and arrives the upper end of the knife body via the inner cavity; when the knife body is worn, the advance knife leaks oil; and the oil transportation system is provided with a pressure gage or a pressure sensor, so that the pressure change of the inner cavity can be intuitively seen, and the worn advance knife can be exactly found; the advance knife for a shield machine with a wear display function has the advantages of being exact in wear display and simple in structure.
Description
Technical field
The utility model relates to a kind of shield machine with the cutter of going ahead of the rest, and relates in particular to a kind of shield machine with wearing and tearing Presentation Function with the cutter of going ahead of the rest.
Background technology
Shield method is the job practices of in broken rock or soil layer, tunneling tunnel with protecting cover special machinery (being shield machine), and the cutterhead of shield machine is provided with cutter, mainly is the rotation that utilizes cutterhead; Rock, soil layer are ditched, rolled and fragmentation etc. by cutter; Cutter generally is divided into scraper, hobboing cutter and the cutter etc. of going ahead of the rest, and wherein cutter is through on cutter hub, opening a lot of holes, in the hole, welding much cemented carbide bodies in advance; Rock, soil layer are carried out fragmentation and roll etc. through alloy body; But the cutter in advance that uses does not at present generally have the wearing and tearing Presentation Function, and perhaps there is limitation at the position of cutter detection wearing and tearing in advance, will make troubles to maintenance like this; Be not easy to find out the cutter that has damaged, thereby can influence the efficient and the quality of whole construction.
The utility model content
The purpose of the utility model is to provide a kind of shield machine with wearing and tearing Presentation Function with the cutter of going ahead of the rest; To solve the position that present shield-tunneling construction do not wear and tear Presentation Function or survey wearing and tearing with cutter in advance circumscribed problem is arranged, having wearing and tearing and showing accurately and advantage of simple structure.
The purpose of the utility model is to realize through following technical scheme:
A kind of shield machine with wearing and tearing Presentation Function is with the cutter of going ahead of the rest; Comprise the fixed axis that interference fit is installed in cutter hub that cemented carbide body is installed and the cutter hub axis hole; Said cutter hub is provided with an inner chamber; Said inner chamber is communicated to the upper end that cutter hub is equipped with cemented carbide body from the lower end of cutter hub, and said inner chamber connects fuel transfer system, and said fuel transfer system is provided with pressure meter or pressure sensor.
The lower end of said cutter hub connects a baffle plate through the symmetrically arranged bolt in the left and right sides.
Said inner chamber comprises vertical cavity and the horizontal cavity that is interconnected, and vertically cavity is through to the upper end of said cutter hub from bolt center, said left side, and horizontal cavity is communicated to said vertical cavity from the right upper portion level of said cutter hub.
The end of said horizontal cavity is provided with plug.
Said left side bolt tube connector joint, and be provided with sealing ring at joint.
The beneficial effect of the utility model is: through the inner chamber that cutter hub is provided with, inner chamber connects fuel transfer system, and the oil of certain pressure is injected from union; Arrive the upper end of cutter hub through inner chamber; When wearing and tearing appearred in cutter hub, the leakage of oil situation will appear in cutter in advance, and said fuel transfer system is provided with pressure meter or pressure sensor; When wearing and tearing appearred in cutter hub, operating personnel can find out intuitively that the pressure of inner chamber changes.In conjunction with above method, can find out the cutter in advance that has worn and torn accurately, have wearing and tearing and show accurately and advantage of simple structure.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 has the structural representation of the shield machine of wearing and tearing Presentation Function with the cutter of going ahead of the rest for the utility model is described.
Fig. 2 is that the A-A shown in Fig. 1 is to cross-sectional schematic.
Among the figure:
1, cemented carbide body; 2, cutter hub; 3, fixed axis; 4, left side bolt; 5, vertical cavity; 6, horizontal cavity; 7, plug; 8, union; 9, sealing ring; 10, native storehouse side fuel transfer system; 11, fore side fuel transfer system; 12, hydraulic rotary joint; 13, pressure meter; 14, baffle plate.
The specific embodiment
In Fig. 1～2 illustrated embodiments, the shield machine that the utility model is described to have a wearing and tearing Presentation Function is with cutter in advance, comprises the fixed axis 3 of interference fit installation in cutter hub 2 that cemented carbide body 1 is installed and cutter hub 2 axis holes; The lower end of cutter hub 2 is connected a baffle plate 14 through symmetrically arranged left side bolt 4 with the right side bolt, bolt 4 center drillings in left side are through to the upper end of cutter hub 2, form a vertical cavity 5; The right upper portion of cutter hub 2 offers horizontal cavity 6; Horizontal cavity 6 is communicated with vertical cavity 5, and the end of horizontal cavity 6 is provided with plug 7, left side bolt 4 tube connector joints 8; And be provided with sealing ring 9 at joint; Union 8 connects native storehouse side fuel transfer system 10, and native storehouse side fuel transfer system 10 connects shield machine fore side fuel transfer system 11 through hydraulic rotary joint 12, and fore side fuel transfer system 11 is provided with pressure meter 13.
Through horizontal cavity 6 and vertical cavity 5 in cutter hub 2 set inside, fore side fuel transfer system 11 is delivered to native storehouse side fuel transfer system 10 with the oil of certain pressure through hydraulic rotary joint 12, injects from union 8 again; Arrive the upper end of cutter hubs 2 through horizontal cavity 6 and vertical cavity 5; The plug 7 that is provided with in the end of horizontal cavity 6, and the sealing ring 9 that the joint of bolt 4 and union 8 is provided with in the left side can be under cutter hub 2 unworn situation; Well with oil seal in cavity; When wearing and tearing appearred in cutter hub 2, the leakage of oil situation will appear in cutter in advance, the pressure meter 13 that fore side fuel transfer system 11 is provided with; When wearing and tearing appear in cutter hub, can find out intuitively that the pressure in the cavity changes.In conjunction with above method, can find out the cutter in advance that has worn and torn accurately, have wearing and tearing and show accurately and advantage of simple structure.
