Abstract
The utility model discloses a tool of a pipe pusher with simple structure and abrasion resistance. The structure of the tool comprises an outer shell of the pipe pusher; a cutter head spiral arm is arranged at the front end of the outer shell of the pipe pusher; a central cutter head is arranged on the middle part of the outer shell of the pipe pusher; a central tool is arranged on the central cutter head; a cutting tool is arranged on the cutter head spiral arm; and a flange tool is arranged at the outer end of the cutter head spiral arm. The tool of the pipe pusher is characterized in that the flange cutter is installed in the direction perpendicular to the force bearing direction of the flange cutter.
Description
Technical field
The utility model is to lay or device assembled conduit or that have placement pipeline or cable unit about having, and more particularly, the utility model is about the push-bench parts.
Background technique
At present, the push-bench cutter head, be adapted at jacking construction in the softer soil layer,, pile up when comparatively closely knit when big in soil layer hardness, wearing and tearing to cutter head are very big, after the edge cutter head lateral angle wearing and tearing, the cutting diameter of whole cutterhead is less than the external diameter of pipe jacking tunnelling machine, and the development machine front end has the part soil body not eliminated, frontal resistance sharply increases, and can cause jacking to interrupt when serious.
The model utility content
Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, provides a kind of simple in structure, nonabradable push-bench cutter head.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: its structure comprises the push-bench shell, described push-bench shell front end is provided with the cutterhead spiral arm, the middle part is provided with the center cutterhead, described center cutterhead is provided with the center cutter head, and described cutterhead spiral arm is provided with cutter tip, and the outer end of cutterhead spiral arm is provided with the edge cutter head, its main points are, the cutter head direction of described edge cutter head with its stressed direction vertical.
Beneficial effect: the utility model compared with prior art has following beneficial effect: increased the contact length of the carbide cutter tool piece and the soil body on the side cutting face, increased the working life of cutter head.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model structural representation.
Accompanying drawing 3 is the utility model cutter head structure schematic representation.
Accompanying drawing 4 is the utility model cutter head structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
Embodiment one:
Referring to accompanying drawing 1, the push-bench cutter head mainly is made of push-bench shell 1, cutterhead spiral arm 6, center cutterhead 4, center cutter head 5, cutterhead spiral arm 6, cutter tip 2, edge cutter head 3 etc.
Described push-bench shell 1 front end is welded with four cutterhead spiral arms 6, four cutterhead spiral arms 6 are the welding of " ten " font, cutterhead spiral arm 6 is welded with two row's cutter tips 2 respectively, every row's cutter tip 2 quantity are 2～3, cutterhead spiral arm 6 tops are welded with two edge cutter heads 3 respectively, and cutter head 3 cutter head directions in edge are vertical with suffered power.
Described push-bench front center is provided with center cutterhead 4, and described center cutterhead 4 is provided with a row center cutter head.
During cutting, preceding cutting face is responsible for by center cutter head 5 and cutter tip 2, and edge cutter head 3 only is responsible for the scraping of side cutting face, has increased the contact length of the carbide cutter tool piece and the soil body on the side cutting face, increases the working life of cutter head.
Embodiment two:
Referring to accompanying drawing 2, accompanying drawing 3 is all installed alloy knife piece 100 in end face and two sides of described tool rest 200, and the length of cut of both direction obviously increases, and the protection tool rest is not frayed, forms the full section cutting of development machine.
Embodiment three:
Referring to accompanying drawing 4; alloy knife piece 100 is miter angle with tool rest 200; in the process of the rotation scraping soil body; the carbide cutter tool piece is subjected to the impact of hard gravel; the alloy knife piece easily ruptures; cutter piece inclination 45 degree are installed; cutter piece and tool rest form three mating faces, and cemented carbide is completely wrapped among the tool rest, has increased area of contact; tool rest adopts the 45# steel; toughness is big, strong shock resistance, and the alloy knife piece is protected effectively by tool rest; strengthen the ability that shock resistance is collided with, prolonged the working life of cutter head.
