Description
Technical field
The utility model relates to a kind of development machine that is used for tunnel piercing, particularly a kind of eccentric multi-shaft multi-cutter disk type development machine that is used for tunnel piercing belongs to the tunnel machine field.
Background technology
Analyze from the function of use in tunnel, the form of fracture of highway tunnel, railway tunnel, subway tunnel, underpass, underground common trench is the most suitable with rectangle, and is the most economical.Yet in Rectangular Tunnel tunneling construction process, owing to can run into problems such as head back of the body soil, head rotation, the settlement Control on ground, the axial line control in tunnel all advance difficulty bigger than circular tunnel.Each the big construction company and the shield structure manufacturer of Japan have carried out the development and the test of each class mechanical type rectangular shield, and wherein successful is the DPLEX rectangular shield that the development of mill heavy industry is broadcast on the Ishikawa island, is a kind of earth pressure balanced shield, EPBS of eccentric multi-shaft knife cutting.It is the development machine of multiaxis hilted broadsword disc type.Domestic 3.8 * 3.8m assembled cutter head formula rectangular top pipe machine that the development of tunnel, Shanghai limited company is then arranged.But for the arbitrary cross-section constructing tunnel of big section, long distance, difficulty is bigger.Find that by literature search China Patent No. is: 95120602.8, name is called: shield tunnel boring machine, application is artificial: Daiho Construction Co., Ltd..This utility model patent has been introduced a kind of shield tunnel boring machine with excavator of parallel connection, it comprises the multistage excessive excavating tool that is divided into that combines with described excavator, excessive excavating tool at different levels with when being controlled independently of each other, can connect mutually by transmission device separately-driven, separately, it provides a kind of can realize excessive effectively excavation mode, the tunnel of the curved shape that can help constructing.Yet it is still a kind of development machine of multiaxis hilted broadsword dish, for the arbitrary cross-section digging of big section, long distance, because the unidirectional rotation of hilted broadsword dish very easily makes development machine that unidirectional skew easily takes place, thereby causes the skew of tunnel axis.Because the radius of gyration of cutting cutterhead is relatively large, the sliding distance of cutter tip is also relatively large, and cutter is easy to wear, is unfavorable for long distance driving.
Summary of the invention
The utility model is at the deficiencies in the prior art and defective, a kind of eccentric multi-shaft multi-cutter disk type development machine is provided, make it can carry out the full section construction of rectangle, by bite disk shape selected and digging section similar shape, the tunnel of all section configuration can also be digging become, and the construction of large cross-section tunnel can be adapted to.In construction, can control earth pressure balance effectively, guarantee that above ground structure is without prejudice, utilize its section configuration to build rectangle and section tunnels such as walkway, cable tunnel and common trench.
The utility model is realized by the following technical solutions, the utility model comprises: cutting cutterhead, cutter plate driver, deviation correcting device, conveying worm, preceding piece housing, back piece housing, base, eccentric shaft, its connected mode is: the cutting cutterhead by about two cutterheads form, be positioned at push pipe foremost, each cutterhead respectively with cutter-devices system in four eccentric shafts pass through Bolt Connection, both sides before two conveying worms are installed on respectively by bolt in the piece housing, the base under the deviation correcting device links up preceding piece housing and back piece housing.The both sides of each oil cylinder all are separately fixed on the base by pin oil cylinder in the deviation correcting device as one group with two, before two wing bases are welded on respectively on piece housing and the back piece housing girth sheets.
As the important component part of eccentric multi-shaft multi-cutter disk type rectangle development machine, the cutting cutterhead is made up of two opposite rectangle cutterheads of direction of rotation, and they need keep when making cutting movement synchronously, after its fortune circles, can cut the full section of rectangle.And single cutterhead is equipped with four rotary driving shafts.With the vertical mode fixed crankshaft, install the cutting cutterhead in the biased heart of their leading section, driving shaft is rotated by same direction, the cutting cutterhead is done the parallel ring motion, makes its energy digging section similar with the bite disk shape.When conversion bite disk shape, just can constitute the shield tunnel of various digging section configurations such as circle, ellipse and the shape of a hoof.Cutter head structure is latticed development machine support, and welded and installed the cross cutter, and all cutters be along with cutterhead can both be gone slick in certain radius, and the cutting on the excavation face is engaged in the full section construction that just can finish the tunnel with these drill bits.
In this kind development machine, two opposite rectangle cutterhead run-in synchronism cutting tunnel cross-sections of direction of rotation are the utility model point.At first the cutting section with big section is divided into two, can reduce the running radius of eccentric shaft, thereby reduces the cutting driving torque, and helps the processing and the installation of eccentric shaft.Secondly, because two cutterheads are done opposite synchronously running, can reduce the external force that produces owing to unidirectional rotation and cause development machine to be offset.
The utility model utilizes two opposite rectangle cutterheads of direction of rotation to make eccentric rotary cutting synchronously, and by front portion cutting soil is improved, makes whole rectangular cross section can obtain fully good cutting, and keeps the stability of excavation face.The cross cutter of installing on cutterhead is that a kind of knife angle, withdrawing angle equate, can make the cutter of comprehensive cutting.Use such cutter head, can cut big gravel and with fiber reinforced strong concrete wall (800kgf/cm
2).Along with the cutting cutterhead is done parallel motion digging stratum, the digging track of all cutter tips is the toroidal of minor diameter.The combination of several cutter cutter head tracks just becomes and can do full face digging.Utilize deviation correcting device correction and two kinds of methods of mud jacking correction can control preferably to the jacking misalignment of axe.Utilization is installed in the opposite conveying worm of two direction of rotation of two bottom sides and carries the soil of cutting, not only can make two ends, the big section left and right sides balance of being unearthed, and can avoid owing to the unidirectional rotation of conveying worm produces revolving force to housing.
The utlity model has substantive distinguishing features and marked improvement, the utility model can carry out full section cutting to arbitrary cross-section, keeps earth pressure balance, and is little to the surrounding soil disturbance; Under equal sectional area, eccentric multi-shaft multi-cutter disk type development machine because the radius of gyration of cutter is little, just can accomplish that the digging torque is less than other form development machines, can reduce to equip moment of torsion, reduces construction cost.And, logarithm platform drive part and two cutterhead parts, owing to can be convenient to install by the miniaturization unit, convey in section is most appropriate to the special-shaped section construction of big section.Because the radius of gyration of cutting cutterhead is little, the sliding distance of cutter tip diminishes, and has reduced the abrasion of cutter head, helps long distance driving.
