Cutting machine and cutting method
The present invention relates to mechanical processing technique and apparatus field, be a kind of by in the pipe to the Apparatus and method for of circumscribed pipe cutting.
In processing practice, some situation need with to caliber below 600 millimeters, the pipe that enters of people's inconvenience outwards cuts pipe internally, for example imbedded in the pipe trench pipe and will clip one section.The steel-pipe pile of architectural engineering also needs such cutting technique in addition: because the complexity of architectural engineering geological conditions, the depth of drive of steel-pipe pile often exists certain error with design, so just causes the steel-pipe pile of building lot normally will exceed one section than design height.And for the building that basement is arranged, the absolute altitude of these steel-pipe piles is at underground several meters.In the time the steel-pipe pile of the underground part that exceeds standard will being cut, because of the earth in the construction is to be wrapped in steel-pipe pile, implement to cut to such an extent that earth is on every side scooped away from steel-pipe pile is peripheral, make the efficient of construction reduce, also easily pile tube is bumped askew; Do not cut the earth earlier and then lack the prerequisite of cutting outside managing.If from the internal implementation cutting of steel-pipe pile, raising efficiency of construction that will be bigger.To outer cutting, can also overcome some and cut the defective that pipe otch bore is dwindled from outside to inside in the reason, be applicable to that some do not allow to cut the construction occasion that the back caliber diminishes.
The Granted publication CN2405696Y of Chinese patent literature publication, the ZL patent No. 00216174.5, name is called " the underground cutter sweep of steel-pipe pile ", this part utility model discloses the underground cutter sweep of a kind of steel steel-pipe pile, comprises mainly circumference cutting speed reducer structure that is made of motor, decelerator, planetary gear and the pneumatic pressure regulating device that constitutes the control loop of mainly being made up of the pneumatic element that comprises solenoid directional control valve, sequence valve and pressure-reducing valve and check valve.It mainly is made of fuselage supporting and positioning mechanism, circumference cutting speed reducer structure, pneumatic pressure regulating device and the pneumatic feeler mechanism of following.Adopt cutting mode in the pipe, can once cut off whole section pile crown, the cutting method of this part patent is to select the high temperature air plasma-arc for use.This patent cutter sweep need hang in pipe with cutting machine with loop wheel machine, thus the pipe that can only be used for directly putting, put into from top to bottom, and also the location of cutting position is difficult for accurately; In addition can the starting the arc in pipe, and the plasma arc cutting effect be can't see, not easy to operate; Compressed air pipe, cable etc. all are hang behinds, and cutting can be twisted together after rotating.The purpose of this invention is to provide a kind of pipe that level places to vertical any position, cutting machine that can cut pipe from inside to outside with multiple manufacturing process put into.
Summary of the invention
The objective of the invention is provides a kind of cutting machine and cutting method to this area, make its pipe that can put into level and place to vertical any position, can be outwards, cut the cutting machine of pipe with multiple manufacturing process by pipe, make it can solve cutting processing under the occasion that does not have condition to cut pipe from outside to inside; Because of its problem that otch bore is dwindled, do not allow to cut the processing occasion that the back caliber diminishes simultaneously applicable to some.The objective of the invention is to be achieved through the following technical solutions.
A kind of cutting machine, this cutting machine is the equipment from the outside quarter sawing pipe cutting of the internal diameter that is cut pipe, it comprises that rotatable platform assembly, locating wheel assembly, locating wheel extend out mechanism, rolling disc, central tube, gear assembly, rotary electric machine, control motor, cutting head, its design main points are that cutting machine is to insert to be cut in the pipe, for not being the vertical pipe of placing, also available central tube and top auxiliary wheel thereof push cutting machine and are cut in the pipe; It stretches into the degree of depth is to regulate by central tube and fixed head, and the mode of adjusting is regulated the length that another section central tube stretches into by the flange that central tube connected; Or the junction between fixed head and the central tube is provided with sleeve pipe and regulating sleeve, regulate the length that central tube stretches into.Described fixed head connects with the end face that is cut pipe, makes the position of cutting machine cutting comparatively accurate.
The also connection rotatable platform assembly of described central tube, the rotatable platform assembly extends out mechanism with rolling disc, locating wheel, the locating wheel assembly connects.
Described rotary electric machine drives rolling disc by gear assembly, and the control motor connects telescoping mechanism; The diametric plane of central tube connects the rotatable platform assembly, and the rotatable platform assembly is provided with rolling disc, locating wheel extends out mechanism, locating wheel assembly, auxiliary wheel carrier.
Described cutting head or select milling cutter cutting for use, or crowded cutter device, both can select one and choose.
Described cutting head or select oxy-acetylene for use, or plasma arc cutting device, both can select one and choose.
Described locating wheel extends out mechanism, the power of telescoping mechanism and rolling disc, or select for use pneumatic or hydraulic pressure drives, both can select one and choose.
A kind of cutting method of cutting machine, its main points are that cutting machine utilizes central tube and top auxiliary wheel carrier thereof, cutting machine are pushed be cut in the pipe, are put into the position that needs cutting; Cut lengths are to regulate by central tube and fixed head; Start locating wheel and extend out mechanism, the locating wheel assembly on the cutting machine is extrapolated, touches the steel-pipe pile inwall, assists the cutting machine location; Telescoping mechanism is extrapolated with cutting head, implements by the cutting of inwall to the external diameter direction; Start rotary electric machine simultaneously, make the rotatable platform assembly rotation of cutting machine, form a circle line of cut, finish and to exceed one section steel-pipe pile by interior radial outer diameter and cut off along the steel-pipe pile inwall.Cutting machine is inserted from be cut pipe, is put into the position that needs cutting, and stretching into the degree of depth is to regulate by central tube and fixed head.
The invention solves the technical problem that the pipe from horizontal positioned to vertical placement cuts pipe from inside to outside, can be used on the technical problem of cutting steel-pipe pile before cutting the earth earlier, improved the efficiency of construction of architectural engineering significantly.
