Abstract
The utility model discloses a single-blade hobbing cutter device with semi-cylindrical and hexagonal end covers for a shield machine, which comprises a cutter body, a cutter shaft and bearings. The cutter body is provided with a cutter head. The single-blade hobbing cutter device with the semi-cylindrical and hexagonal end covers for the shield machine is characterized in that a left end cover and a right end cover are respectively arranged on the left side and the right side of the cutter shaft. The left end cover and the right end cover are in semi-cylindrical shapes in a transverse direction. The fixed portions of the left end cover and the right end cover are in hexagonal shapes in a longitudinal direction. One end cover is connected with the cutter shaft through a bolt. A partition ring is arranged between bearings. The single-blade hobbing cutter device with the semi-cylindrical and hexagonal end covers for the shield machine has the advantages that the left end cover and the right end cover are in semi-cylindrical shapes in a transverse direction, and the fixed portions of the left end cover and the right end cover are in hexagonal shapes in a longitudinal direction, thereby having compact structure, keeping fixed form of the hexagonal end cover and facilitating cutter changing operation in earth bins.
Description
Technical field
The utility model relates to a kind of shield machine semicolumn hexagon 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 hexagon 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 hexagon end cap.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of shield machine semicolumn hexagon 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 hexagon at longitudinal direction, and 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 hexagon at 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; The fixed form that keeps the 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 the utility model embodiment;
Fig. 3 is the structural representation of the said right end cap of the utility model embodiment;
Fig. 4 is the said embodiment general structure of a utility model schematic top plan view
Among the figure:
1, right end cap; 2, spacer ring; 3, dynamic seal; 4, bearing; 5, cutter head; 6, cutter hub; 7, left end cap; 8, bolt; 9, cutter shaft; 10, boss; 11, semicolumn curved surface.
The specific embodiment
Shown in Fig. 1 to 4, provided a specific embodiment of the utility model, among the figure; Comprise cutter hub 6, cutter shaft 9, bearing 4 and spacer ring 2, on the said cutter hub 6 cutter head 5 is installed, the left and right sides of said cutter shaft 9 is respectively arranged with left end cap 7 and right end cap 1;, as shown in Figure 4, said left and right end cap is half-cylindrical at horizontal direction; The outline of each end cap is that radius is the semicolumn curved surface 11 of R; The standing part of said left and right end cap is hexagon at longitudinal direction, and left end cap 1 connects with cutter shaft 9 usefulness bolts 8, and spacer ring 2 is installed between the said bearing 4; Be provided with dynamic seal 3 between cutter hub 6 and left end cap 7 and the right end cap 1; For conveniently installing and fixing, left and right end cap is provided with boss 10.
The utility model is equipped with spacer ring 2 between bearing 4, purpose is the end play that controllable shaft is held, and guarantees the reliability that hobboing cutter is worked under various loads; Because said left and right end cap is half-cylindrical at horizontal direction; The standing part of said left and right end cap is hexagon at 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; The fixed form that keeps the hexagon end cap again more helps tool changing operation in the native storehouse; Between cutter hub 6 and left end cap 7 and right end cap 1, be provided with dynamic seal 3, 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.
