Abstract
The invention belongs to the field of a mounting technology of an inner cutter of a disc cutter on the cutter head of a full-face tunnel boring machine, and particularly relates to an anti-tipping mounting method of an inner cutter of a disc cutter on the cutter head of a full-face tunnel boring machine. A mounting seat for the inner cutter of the disc cutter on the cutter head is provided with a bracket and an inner cutter of the disc cutter supported by the bracket; and the plane of the inner cutter blade of the disc cutter on the cutter head is formed by rotating the plane of the inner cutter blade of the disc cutter in a positive mounting mode for an angle lambdai along the rotation direction of the cutter head in the boring direction by taking the diameter of the maximum penetration point of the inner cutter of the disc cutter on the cutter head as an axle. The method can effectively avoid lock of the inner cutter of the disc cutter on the cutter head due to excessive axial force generated by side slip in the operation process of the inner cutter of the disc cutter on the cutter head and avoid consequent tipping of the inner cutter of the disc cutter on the cutter head, and can reduce the cutter replacing frequency, save the engineering construction cost and shorten the engineering construction period.
Description
Technical field
The invention belongs to the positive cutter mounting technique of disk cutter field on the complete-section tunnel boring machine cutterhead, the anti-tipping mounting method of the positive cutter of disk cutter on particularly a kind of complete-section tunnel boring machine cutterhead.
Background technology
The installation of the positive cutter of disk cutter on cutterhead all is just to install on the cutterhead of complete-section tunnel boring machine plane at present.Adopt this mounting means,, have the positive cutter of disk cutter about 10 to lose efficacy because of tipping takes place according to engineering statistics.Through theoretical calculate proof main cause of the positive cutter generation of disk cutter tipping on the cutterhead of plane is because the positive cutter of the excessive disk cutter that causes of its lateral force is stuck and causes, thereby, reduce even eliminate the uneven lateral force of the positive cutter of disk cutter in construction, just can avoid it to be stuck, thereby eliminate the tipping that the positive cutter of disk cutter occurs in engineering construction.
Summary of the invention
The present invention is directed to the tipping loss problem that the positive cutter of disk cutter occurs in construction, proposed a kind of anti-tipping mounting method that is used for the positive cutter of disk cutter on the complete-section tunnel boring machine cutterhead.
The technical solution used in the present invention is:
On the cutterhead mount pad of the positive cutter of disk cutter, carriage is set, and by the positive cutter of the disk cutter of bracket support; The plane, blade place of the positive cutter of disk cutter is that the plane, disk cutter positive blade place of positive mounting means is an axle with the diameter of invading dark point by its maximum, looks along tunneling direction, along angle λ of cutterhead direction of rotation rotation
i, this angle
Wherein, r is the positive cutter radius of disk cutter, R
IpBe the trace radius of the positive cutter of disk cutter, h is the average cutting-in of the positive cutter of disk cutter, and χ is the broken rock sword territory of the positive cutter of a disk cutter pressure distribution index, is 0≤χ≤1.
Described included angle X
iImplementation be: the position of the positive cutter mount pad of disk cutter is about the cutter diameter symmetry, and the position of screw is the center with mount pad to the center of holding, and looks along the direction rotation λ of cutterhead rotation along the complete-section tunnel boring machine tunneling direction
iThe angle; Perhaps the position of the positive cutter mount pad of disk cutter is the center with it to the center of holding, and looks along the direction rotation λ of cutterhead rotation along the complete-section tunnel boring machine tunneling direction
iThe angle.
Beneficial effect of the present invention is: use the present invention can effectively reduce the lateral force in the broken rock work of the positive cutter of disk cutter, prevents to be stuck in the broken rock work of the positive cutter of disk cutter on the cutterhead, helps reducing the engineering construction cost, shortens the duration of a project.
Description of drawings
Fig. 1 is a mounting means schematic diagram of the present invention;
Fig. 2 is a screwhole position schematic diagram on the positive cutter mount pad of disk cutter.
Number in the figure:
The positive cutter of 1-disk cutter; The 2-carriage; The positive cutter mount pad of 3-disk cutter; The 4-cutterhead; The 5-screw.
The specific embodiment
The invention provides the anti-tipping mounting method of the positive cutter of disk cutter on a kind of complete-section tunnel boring machine cutterhead, the present invention will be further described below by description of drawings and the specific embodiment.
Fig. 1 is the schematic diagram of mounting method of the present invention.On the mount pad 3 of the cutterhead 4 of the positive cutter of disk cutter, carriage 2 is set, and the positive cutter 1 of disk cutter that supports by carriage 2.
The plane, blade place of the positive cutter of disk cutter is that the plane, disk cutter positive blade place of positive mounting means is an axle with the diameter of invading dark point by its maximum, looks along tunneling direction, along angle λ of cutterhead direction of rotation rotation
i, and
Wherein, r is the positive cutter radius of disk cutter, R
IpBe the trace radius of the positive cutter of disk cutter, h is the average cutting-in of the positive cutter of disk cutter (a revolution cutterhead driving amount), and χ is that the broken rock sword territory of the positive cutter of disk cutter pressure divides not index, is determined by concrete engineering rock matter condition, is generally 0≤χ≤1.
The disk cutter positive blade place plane included angle λ of the plane, blade place of the positive cutter 1 of disk cutter and conventional mounting mode
iImplementation be:
(1) position of the positive cutter mount pad 3 of disk cutter is about the cutter diameter symmetry, and the position that the positive cutter of disk cutter is installed screw 5 is the center with the mount pad symmetrical centre, looks along the complete-section tunnel boring machine tunneling direction and rotates (broken rock motion) direction rotation λ along cutterhead
iThe angle, concrete mode is referring to Fig. 2; Adopt this mode to realize, the positive cutter of disk cutter does not have interchangeability, and promptly the positive cutter of the disk cutter of optional position cannot exchange;
(2) position of the positive cutter mount pad 3 of disk cutter is the center with its symmetrical centre, looks along the complete-section tunnel boring machine tunneling direction and rotates (broken rock motion) direction rotation λ along cutterhead
iThe angle; Adopt this mode to realize, the positive cutter of disk cutter has interchangeability, and promptly the positive cutter of the disk cutter of optional position can exchange.
