Abstract
The utility model discloses a double-edged hob device for a semi-cylindrical hexagonal end cover of a shield machine. The double-edged hob device comprises a cutter body, a cutter shaft and a bearing, wherein a cutter bit is arranged on the cutter body; a left end cover and a right end cover are arranged on the left side and the right side of the cutter shaft respectively; the left and right end covers are semi-cylindrical in the horizontal direction; fixed parts of the left and right end covers are hexagonal in the longitudinal direction; the left and right end covers are connected with the cutter shaft through bolts; and a spacing ring is arranged below the bearing. The utility model has the advantages that: a double-edged hob is cylindrical in the horizontal direction except cutting edges, so that the double-edged hob device can be arranged in a hollow cylindrical cutter box; simultaneously, double edges are arranged in a limited spaced, so that the rock breaking efficiency of the hob which is operated under various loads is ensured, and the replacement difficulty of the hob is reduced.
Description
Technical field
The utility model relates to a kind of shield machine semicolumn hexagon end cap twolip 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 two, the broken cutters that the rock amount is big, efficiency of breaking rock is high of structure letter in the shield cutter, is mainly used in the fragmentation, hard rock; The twolip disk cutter then with the two structure of its letter, 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,, be easy to generate the problem of hobboing cutter axial displacement and seal failure in case run into complicated geology.
The utility model content
The utility model provides a kind of shield machine semicolumn hexagon end cap twolip hobboing cutter device; Run into complex geological conditions at present to solve; Hobboing cutter is easy to generate the problem that axial displacement, seal failure and hobboing cutter are changed difficulty, changes difficulty to guarantee the efficiency of breaking rock that hobboing cutter is worked under various loads with the minimizing hobboing cutter.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of shield machine semicolumn hexagon end cap twolip 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 left end cap and cutter shaft connect with bolt, and the below of said bearing is equipped with spacer ring.
For further realizing the beneficial effect of the utility model, be provided with dynamic seal between said cutter hub and the left and right end cap; Said left and right end cap is provided with boss; Between the said cutter head spacer ring is installed.
The beneficial effect of the utility model is: because spacer ring is installed below bearing, so the controllable shaft end play of holding, guarantee the reliability that hobboing cutter is worked under various loads; Because left end cap and cutter shaft are used Bolt Connection, improved the rigidity of axle; Because left and right end cap is the semicolumn hexagon; And left and right end cap is provided with boss, can be contained in the special cutter head of shield machine, compares with the hobboing cutter of other type; Boss can play fixing and spacing effect to hobboing cutter, makes this device have the big advantage of integral rigidity; Owing between cutter hub and left and right end cap, be provided with dynamic seal, make said shield machine semicolumn hexagon end cap twolip hobboing cutter device have the better seal effect.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model overall appearance structural representation;
Fig. 2 is the utility model general structure part subdivision schematic top plan view;
Fig. 3 is the surface structure sketch map of the utility model left end cap;
Fig. 4 is the surface structure sketch map of the utility model right end cap.
Among the figure:
1, left end cap; 2, spacer ring; 3, dynamic seal; 4, bearing; 5, cutter head; 6, cutter hub; 7, right end cap; 8, bolt; 9, cutter shaft; 10, boss; 11, circular curve; 12, spacer ring; 13, bolt hole.
The specific embodiment
As depicted in figs. 1 and 2, provided the specific embodiment of the utility model, among the figure, comprise cutter hub 6, cutter shaft 9, bearing 4 and spacer ring 2, cutter head 5 is installed on the cutter hub 6, spacer ring 12 is installed between the cutter head 5; The left and right sides of cutter shaft 9 is respectively arranged with left end cap 1 and right end cap 7; The below of bearing 4 is equipped with spacer ring 2, and purpose is the end play that controllable shaft is held, and guarantees the reliability that hobboing cutter is worked under various loads; Between cutter hub 6 and left end cap 1 and right end cap 7, be provided with dynamic seal 3, make the shield machine roller cutter device have the better seal effect.
As shown in Figure 2, said left and right end cap (1,7) is half-cylindrical at horizontal direction, and left and right end cap (1,7) horizontal direction is circular curve 11 shapes, and the standing part of said left and right end cap (1,7) is hexagon at longitudinal direction.Such design can guarantee compact conformation, can keep the fixed form of hexagon end cap again.
Shown in Fig. 2 to 4, left end cap 1 connects with cutter shaft 9 usefulness bolts 8, is in order to have improved the rigidity of axle like this; Left end cap 1, right end cap 7 are provided with bolt hole 13 so that hobboing cutter is fixed within the cutter box; Institute is because left end cap 1 is semicolumn and hexagon with right end cap 7 respectively at both direction; Left end cap 1 is provided with boss 10 with right end cap 7; Boss 10 can play fixing and spacing effect to hobboing cutter; Can be contained in the special cutter head of shield machine, compare with the hobboing cutter of other type, this device has the big advantage of integral rigidity.
Therefore, the described shield machine semicolumn of the utility model hexagon end cap twolip hobboing cutter device has under complex geological conditions, and hobboing cutter is difficult for producing the problem of seal failure, has the advantage that compact conformation is easy to change hobboing cutter simultaneously.
