Abstract
The utility model discloses a semi-cylindrical arc end cover single-blade hobbing cutter device of a shield machine, which includes a cutter body, a cutter shaft and bearings, and a cutter head is mounted on the cutter body. The semi-cylindrical arc end cover single-blade hobbing cutter device is characterized in that a left end cover and a right end cover are arranged on the left and the right sides of the cutter shaft respectively; the left and the right end covers are semi-cylindrical in the transverse direction; the fixed parts of the left and the right end covers are semi-cylindrical arc below the longitudinal direction; one end cover is bolted with the cutter shaft; and spacer rings are mounted between the bearings. The utility model has the benefits that as the left and the right end covers are semi-cylindrical in the transverse direction, and the fixed parts of the left and the right end covers are semi-cylindrical arc below the longitudinal direction, the hobbing cutter device has a compact structure, the rectangular block of the hobbing cutter on a cutter head can lock the end covers, and cutter replacing in a clay warehouse is facilitated.
Description
Technical field
The utility model relates to a kind of shield machine semicolumn arc end cap single-blade hobboing cutter device.
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); The cutterhead of shield machine is provided with cutter; It mainly is the rotation that utilizes cutterhead; Rock, soil layer etc. are ditched, rolled and fragmentation etc. by cutter, hobboing cutter is simple in structure in the shield cutter, the broken cutter that the rock amount is big, efficiency of breaking rock is high, is mainly used in the fragmentation, hard rock; The single-blade disk cutter then with its simple structure, higher efficiency of breaking rock with than the long life characteristics, is widely used in the shield machine.Yet in present shield-tunneling construction engineering, in case run into complicated geology or hobboing cutter wearing and tearing, carry out frequent tool changing, but hobboing cutter is because of structural factor, volume is not compact, and because of the inclement condition of Tu Cang, makes tool changing very difficult.
The utility model content
The utility model provides a kind of shield machine semicolumn arc end cap single-blade hobboing cutter device, to solve the not compact problem of hobboing cutter structure of the fixed hobboing cutter device of present hobboing cutter rectangular block end cap.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of shield machine semicolumn arc end cap single-blade hobboing cutter device; Comprise cutter hub, cutter shaft and bearing, on the said cutter hub cutter head is installed, the left and right sides of said cutter shaft is respectively arranged with left end cap and right end cap; Said left and right end cap is half-cylindrical at horizontal direction; The standing part of said left and right end cap is cylindrical radial below longitudinal direction, end cap and cutter shaft connect with bolt, and spacer ring is installed between the said bearing.
Be provided with dynamic seal between said cutter hub and the left and right sides end cap; Said left and right end cap is provided with boss.
The beneficial effect of the utility model is: because said left and right end cap is half-cylindrical at horizontal direction; The standing part of said left and right end cap is cylindrical radial below longitudinal direction,, can be contained in the corresponding cylinder hobboing cutter cutter box; Compare with the hobboing cutter of other type; This device has the advantage of compact conformation, keeps the fixed form of hexagon end cap again, more helps tool changing operation in the native storehouse; Between cutter hub and left end cap and right end cap, be provided with dynamic seal, make said shield machine roller cutter device have the better seal effect.Therefore have under complex geological conditions, hobboing cutter is difficult for producing the problem of seal failure.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the said embodiment general structure of a utility model sketch map;
Fig. 2 is the structural representation of the said left end cap of embodiment;
Fig. 3 is the structural representation of the said right end cap of embodiment;
Fig. 4 is the said embodiment general structure of a utility model schematic top plan view.
Among the figure:
1, cutter shaft; 2, right end cap; 3, bearing; 4, dynamic seal; 5, cutter hub; 6, cutter head; 7 spacer rings; 8, bolt hole; 9, boss; 10, left end cap; 11, bolt; 12, semicolumn curved surface; 13, semicolumn arc.
The specific embodiment
Shown in Fig. 1 to 4; Provided a specific embodiment of the utility model, this single-blade hobboing cutter device comprises cutter hub 5, cutter shaft 1 and bearing 3, on the said cutter hub 5 cutter head 6 is installed; The left and right sides of said cutter shaft 1 is respectively arranged with left end cap 10 and right end cap 2; Said left end cap 10 is half-cylindrical with right end cap 2 at horizontal direction, is semicolumn curved surface 12, and the standing part of said left and right end cap is semicolumn arc 13 below longitudinal direction; Left end cap 10 connects with cutter shaft 1 usefulness bolt 11, and spacer ring 7 is installed between the said bearing 3.Be provided with dynamic seal 4 between cutter hub 5 and left end cap 10 and the right end cap 2.
The said device of the utility model is equipped with spacer ring 7 between bearing 3, purpose is the end play that controllable shaft is held, and guarantees the reliability that hobboing cutter is worked under various loads; Left end cap 10, right end cap 2 and cutter shaft 1 usefulness bolt 11 connect, and have improved the rigidity of axle; Said left end cap 10 is half-cylindrical with right end cap 2 at horizontal direction; Left end cap 10 is provided with boss 9 with right end cap 2; 9 pairs of hobboing cutters of boss play fixing and spacing effect; Can be contained in the corresponding cylinder hobboing cutter cutter box, keep the rectangular block fixed form of hobboing cutter end cap simultaneously again, more help tool changing operation in the native storehouse;
Simultaneously, between cutter hub 5 and left end cap 10 and right end cap 2, be provided with dynamic seal 4, make said shield machine roller cutter device have the better seal effect, therefore have under complex geological conditions, hobboing cutter is difficult for producing the problem of seal failure.
