Abstract
The utility model discloses a fixing structure of a hobbing cutter with square end covers of a shield machine, which comprises the hobbing cutter, a cutter box, wedge-shaped blocks, a bolt, chamfered grooves, conical check blocks and a cutter face plate. End covers of the hobbing cutter are in square shapes and placed in the cutter box, and outlines of the end covers in another direction are circular arc. The cutter box is in a hollow cylindrical shape, and four chamfered grooves are arranged in the cutter box. The conical check blocks are arranged respectively below a left end cover, a right end cover and the chamfered grooves and integrally welded with the cutter box. Conical surfaces of the conical check blocks are mutually matched with two lateral faces of the end covers of the hobbing cutter to be positioned. Two lateral faces of the chamfered grooves are mutually matched with the other two lateral faces of the square end covers through the lateral faces of the wedge-shaped blocks to be positioned. Because the chamfered grooves are arranged in the cutter box, spaces for installing and dismounting the hobbing cutter are enlarged. Because the conical check blocks, the wedge-shaped blocks and the chamfered grooves are arranged and mutually matched with end faces of the hobbing cutter, the hobbing cutter and the cutter box are fixed more firmly, and the cutter box is easy to manufacture simultaneously.
Description
Technical field
The utility model relates to the fixed structure of the square end cap hobboing cutter of a kind of shield machine.
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, because general hobboing cutter cutter box is a rectangular configuration, the processing welding capacity is big, and cost is than higher, and precision is inaccurate, because of welding quantity is big, makes that the shield machine cost is higher.Though it is cylindrical structural that hobboing cutter cutter box is also arranged, fixed form is comparatively simple, adopts bolt that hobboing cutter directly is connected on the hobboing cutter cutter box, so comparatively simple fixed form, and under abominable working condition, reliability is bad, dismounting inconvenience.
The utility model content
The utility model provides a kind of fixed structure of shield machine roller cutter, to solve the fixing difficulty of hobboing cutter in the present shield-tunneling construction, reaches the problem that the processing and manufacturing difficulty is big, cost is high of hobboing cutter cutter box.
For realizing above-mentioned purpose, adopt following technical scheme:
The fixed structure of the square end cap hobboing cutter of a kind of shield machine; Comprise hobboing cutter, cutter box, wedge, bolt, chamfered groove, taper block and cutterhead panel; The end cap of said hobboing cutter is square, and its other direction profile is circular arc and is placed in the cutter box, and said cutter box is hollow cylindrical; Be provided with 4 chamfered grooves in the said cutter box; Below left and right end cap and chamfered groove, respectively be provided with the taper block and be one, the location that cooperatively interacts, the conical surface of said taper block and the hobboing cutter end cap two sides location that cooperatively interacts, other two sides of two sides of said chamfered groove and square end cap the side through wedge with cutter box weldering.
Said end cap is provided with boss and wedge is carried out spacing to prevent the wedge shifted laterally.
Said bolt is connected in the cutter box on the threaded cylinder in the cylindrical hole through wedge, is fastened in the cutter box thereby make wedge compress hobboing cutter.
The beneficial effect of the utility model is: owing in hollow cylinder cutter box, offer chamfered groove; Increased the space of installation and removal hobboing cutters; Owing to be provided with taper block, wedge and chamfered groove, and cooperatively interact, make fixing of hobboing cutter and cutter box more firm with the end cap side of hobboing cutter; Hollow cylinder cutter box is easy to processing and manufacturing simultaneously, welding capacity is few, has reduced the cost of making the cutter box.
