Abstract
The invention relates to an all-cross-section cutting rectangular pipe-pushing machine cutting mechanism used in rectangular pipe-pushing devices used in non-excavation engineering. The mechanism comprises an installing seat, four cutterheads with cutting surfaces located on the same plane are installed on the front end face of the installing seat, centers of rotating shafts of the four cutterheads are respectively located on four vertexes of a square and are driven by an identical spindle located at the center of the installing seat to synchronously rotate at a uniform speed, the end face contour of every cutterhead is a long shape with the dimension in the length direction larger than the dimension in the width direction, cutting blades are arranged on the edge of the cutterheads, the length direction of every cutterhead is perpendicular to the length direction of the cutterheads adjacent to the cutterhead, the maximum cutting radius of every cutterhead and the maximum cutting radius of the adjacent cutterhead have an overlapped part, and the four cutterheads do not interfere with each other when rotating synchronously at the uniform speed. Rectangular all-cross-section cutting can be achieved, the all-cross-section cutting rectangular pipe-pushing machine cutting mechanism is high in difficulty overcoming capability, simple in structure and high in reliability, the technical requirements for constructors are low, and soil mass is mixed fully.
Description
Technical field
The present invention relates to a kind of underground engineering construction equipment, the full section cutting rectangular pipe jacking machine cutting mechanism used in the rectangular top pipe equipment that specifically a kind of trenchless engineering is used.
Background technology
Non-excavation underground construction jacking construction is a kind of hand excavation of replacement pipeline laying method, only need, at starting point and the terminal excavation active well of pipeline laying, use pipe jacking equipment to utilize hydraulic jack directly in underground soil layer, to tunnel, by pipeline communication.
Rectangular top pipe is a kind of in jacking construction, is mainly used in the non-excavating construction of the engineerings such as subway walkway, high voltage cable.It uses rectangular duct to carry out pipelining, and relatively traditional circular push pipe net sectional area is large, the adaptation size range is wide, the space availability ratio advantages of higher.
The cutting mechanism of existing rectangular top pipe equipment mainly contains following several form:
1, many parallel axes eccentric rotary (profiling frame) structure.It drives whole Cutting tool rotary cutting under its acting in conjunction by multiaxis (being generally 4 axles).Its defect is: the technique realization is more difficult, product reliability is lower, soil body stirring is insufficient, transmission efficiency is low.
2, swinging, telescopic cutter head structure.It increases by one group of auxiliary blade row driven by deflecting wheel behind at cutterhead.In the process that the operator dish swings, by the predetermined movement orbiting motion, realize cutting.Its defect is: complex structure, sealing difficulty, transmission efficiency are low.
3, size combinations cutter head structure.It is combined by a plurality of cutterheads, makes Cutting trajectory be similar to rectangle.Its defect is: non-full section cuts (80-85%), the ability of getting rid of poverty is lower, soil body stirring is inhomogeneous.
4, multi-cutter-disk overlapping combination structure.It,, by the placement of staggering before and after a plurality of same cutterheads, makes Cutting trajectory be similar to rectangle.Its defect is: the ability of getting rid of poverty is lower, the soil body stirs inhomogeneous.
5, multi-cutter-disk public affairs-Self-rotation structure.In the time of by the rotation of pocket knife dish, along built-in gear ring revolution, with gear ring, control the cutterhead attitude and accomplish full section cutting.Its defect is: manufacture is difficult, reliability is very low, difficulty of construction is had relatively high expectations to operating personnel more greatly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can realize that the full section of rectangle cuts, the ability of getting rid of poverty is strong, simple in structure, reliability is high,, soil body stirring fully full section cutting rectangular pipe jacking machine cutting mechanism low to constructor's technical requirements.
Full section cutting rectangular pipe jacking machine cutting mechanism of the present invention includes a mount pad, cutting face is installed on the mount pad front end face and is positioned at conplane four cutterheads; The spindle central of four cutterheads lays respectively on foursquare four summits, and by the synchronous constant speed rotation of same main shaft drives that is positioned at the mount pad center; The end profile of cutterhead is that lengthwise dimension is greater than the microscler of width size, and the edge of cutterhead is placed with cutting edge; The length direction of each cutterhead is perpendicular to the length direction of the cutterhead be adjacent, and the maximum radius of clean-up of the maximum radius of clean-up of each cutterhead and adjacent cutterhead has equitant part, do not interfere with each other while making four synchronous constant speed rotations of cutterhead.
Described mount pad top is provided with inspection eye.
Both sides, described mount pad top are provided with inlet opening.
Described mount pad bottom is provided with the conveying worm entrance.
Advantage applies of the present invention exists:
1, can realize the cutting of full section: 4 cutterheads move in a circle around transmission output shaft separately, and the movement locus of 4 circles is interfered with each other, and form the movement locus that is similar to rectangle.The cutting face accounting reaches more than 95%.
2, the stronger ability of getting rid of poverty: 4 cutterheads can be by same main shaft drive work, during its work, arbitrary cutterhead meets with obstruction, rotational resistance progressively increases, in the time of can't continuing jacking, other cutterheads form the idling mode that is not subjected to head resistance, its hydraulic power can be passed to the cutterhead that is obstructed, equipment dynamic more than 75%, act on the position of being obstructed jointly the time, so the ability of getting rid of poverty of type equipment is greatly improved.
3. structure is relatively simple: 2 rank transmissions only occur in transmission case.Only slightly complicated than traditional circular push-bench.Can use the sealing system of ripe circular push-bench, make the reliability of its sealing higher.Therefore can enhance productivity, reduce and manufacture risk, construction risk, reduction accident rate.
4. the soil body stirs fully: owing at drive mechanism, having solved the cutterhead interference problem.Therefore all cutterheads, all in same work plane work, make the soil body fully to be stirred.
