Abstract

The utility model relates to a cutting machine of machining equipment, which is designed aiming at the problem that the construction efficiency is reduced as the cleaning of the longer section of a pile foundation work in the constructional engineering is to carry out cutting from the periphery of a steel pipe pile. The design key point is that the cutting machine is placed in the steel pipe pile, the depth stretching into the steel pipe pile is regulated by a central pipe and a fixed plate; the central pipe is fixedly connected with the plane of the steel pipe pile; a rotatable platform component of the diametric plane connection is connected with a rotating disc, a locating wheel external extending mechanism and a locating wheel component. The output shaft of a rotatable electrical motor is connected with a gear assembly, an electrical conduction sliding block component and the rotating disc. A control motor is connected with an extension planker; a cutting electrical motor is connected with the extension planker and a grinding wheel; the diametric plane of the central pipe is connected with the locating wheel external extending mechanism and an auxiliary wheel carrier; and the auxiliary wheel supplies driving force for the grinding wheel which rotates at a high speed and forms a circle of cutting line along the inner wall of the steel pipe pile so as to cut off the steel pipe pile, the inner diameter of which is one section higher than the outer diameter. The cutting machine solves the technical problem of the steel pipe pile cutting and is particularly suitable for project cleaning in the pile foundation work concluding stage.

Description

Cutting machine

Technical field

The utility model relates to mechanical processing technique and apparatus field, be a kind of by in the pipe to the equipment of circumscribed pipe cutting.

Background technology

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 utility model provides 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 purpose of this utility model is to provide a kind of cutting machine 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 purpose of this utility model is to be achieved through the following technical solutions.

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.

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, and locating wheel extends out mechanism, locating wheel assembly, auxiliary wheel carrier; Diametric plane connection locating wheel at central tube extends out mechanism, auxiliary wheel carrier.

The output shaft attachment tooth wheel assembly of described rotary electric machine drives rolling disc, rotatable platform rotation.The control motor can be controlled flexible planker, carries out cutting operation; Cutting motor connects flexible planker and grinding wheel; Diametric plane connection locating wheel at central tube extends out mechanism, auxiliary wheel carrier; Auxiliary wheel carrier is usefulness when cutting machine is put into the pipe that keeps flat, and when pipe is directly put in cutting, also can not adorn.

Motor on the described rotatable platform is powered by the conductive slider assembly.

The utility model has solved 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, has improved the efficiency of construction of architectural engineering significantly.
