Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described Embodiment is a part of embodiment of this utility model, rather than the embodiment of whole.Based on the embodiment in this utility model, this The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality Novel protected scope.

As depicted in figs. 1 and 2, the cutting equipment of the present embodiment includes support meanss and cutter sweep 30, support meanss bag Include：Support meanss include：Supportive body 11, structure, radial direction drive mechanism and driving structure are radially supported, supportive body 11 is used for In the inner support cutter sweep 30 of pipeline 50；Radially support structure setting and structure is supported on supportive body 11, radially along support master The inwall to support pipeline 50 flexible in the radial direction of body 11, is that cutter sweep 30 provides support in pipeline 50；Radially pass Dynamic structure setting is connected on supportive body 11 and with radially structure is supported, driving of the radial direction drive mechanism in driving structure 12 Under, drive radial direction to support structure and stretch along the radial direction of supportive body 11.Cutter sweep includes：Chopping wheel 31, cutter 32nd, radial direction transmission component and the first drive mechanism, chopping wheel 31 is rotatably supported on supportive body 11；Cutter 32 set Put on chopping wheel 31；Radial direction transmission component is arranged on chopping wheel 31 and is connected with cutter 32, and radial direction transmission group Part drives cutter 32 to move along the radial direction of chopping wheel 31 under the driving of the first drive mechanism 33.

Using the cutting equipment of the present embodiment, before cutting pipeline 50, cutting equipment is placed on into the inside of pipeline 50.Cut During pipe cutting road 50, under the driving of driving structure 12, radial direction drive mechanism drives and radially supports structure along the footpath of supportive body 11 Move to direction towards the inwall of pipeline 50, support on the inwall of pipeline 50 until radial direction supports structure, at this moment cutting equipment It is supported on the inwall of pipeline 50, then under the driving of the first drive mechanism 33, radial direction transmission component drives the edge of cutter 32 The radial direction of chopping wheel 31 is moved towards the inwall of pipeline 50, meanwhile, chopping wheel 31 drives cutter 32 to rotate, so as to So that cutter 32 are contacted and cut with the inwall of pipeline 50.After cutting is finished, under the driving of the first drive mechanism 33, Radial direction transmission component drive cutter 32 along chopping wheel 31 radial direction towards pipeline 50 axle center move, cutter 32 with The inwall of pipeline 50 is separated, and then drives the radial direction for radially supporting structure along supportive body 11 to move towards the axle center of pipeline 50 It is dynamic, radially support structure and separate with the inwall of pipeline, cutting equipment is taken out from pipeline 50.So in pipeline 50 Cutting equipment is placed in portion, and support meanss are that cutter sweep 30 provides support, and cutter sweep is carried out from the inside of pipeline to pipeline Cutting, not by the situation of the narrow space between pipeline and pipeline, is adapted to the intensive occasion of pipeline arrangement, is easy to remove arrangement Wherein one of intensive pipeline, effectively overcomes in prior art and cannot be used for metal tube to the cutting equipment of cuts in metallic pipe The defect that densely arranged occasion is cut.

As shown in Fig. 8 to Figure 10, radial direction transmission component includes：Movable claw 41 and movable claw matable assembly, movable claw 41 sets Put on chopping wheel 31 and be connected with cutter 32；Under the driving of the first drive mechanism 33, movable claw matable assembly drives Movable claw 41 is moved along the radial direction of chopping wheel 31.Movable claw 41 can be with respect to chopping wheel 31 and along the radial direction of chopping wheel 31 Move in direction.Specifically, under the driving of the first drive mechanism 33, movable claw matable assembly drives movable claw 41 along chopping wheel 31 radial directions are moved, and then movable claw 41 drives cutter 32 to move along the radial direction of chopping wheel 31.Said structure can be with It is easy to drive cutter 32 to move, simple structure is easy to operate.

Because chopping wheel 31 can be rotation in cutting, in order to prevent the movable claw 41 can relative 31 turns of chopping wheel It is dynamic.In the present embodiment, movable claw 41 is limited on chopping wheel 31, is only capable of being moved along the radial direction of chopping wheel 31. Movable claw 41 and chopping wheel 31 can not can be rotated relative to chopping wheel 31 with synchronous axial system.It can be seen that, movable claw 41 are merely able to be moved along the radial direction of chopping wheel 31, and then cutter 32 can be driven to move, and pipeline 50 is cut.

As shown in Figure 10, it is preferable that movable claw matable assembly includes：Rotating disk 42 and draw-in groove 411, rotating disk 42, rotationally It is arranged on chopping wheel 31, the surface of rotating disk 42 is provided with the first spiral salient 421；Draw-in groove 411 is arranged on movable claw 41 And be engaged with the first spiral salient 421；First drive mechanism 33 is rotated by driving rotating disk 42, drives movable claw 41 along cutting The radial direction of rotating disk 31 is moved.The driving rotating disk 42 of first drive mechanism 33 is rotated, and rotating disk 42 is rotated and drives movable claw 41 along cutting The radial direction of rotating disk 31 is moved, and then movable claw 41 drives cutter 32 to move along the radial direction of chopping wheel 31, can be to pipe Cut in road 50.In other embodiments, it is also possible to helical groove is set on the surface of rotating disk 42, is set on movable claw 41 There are the multiple projections being adapted with helical groove.

Preferably, draw-in groove 411 is multiple, moving direction interval setting of the multiple draw-in grooves 411 along movable claw 41.So can be with Ensure that movable claw 41 moves more stable, it is also possible to prevent from being skidded off from rotating disk 42 because the draw-in groove 411 on movable claw 41 is very few and Situation.

In the present embodiment, pipeline 50 is metal tube.Certainly, pipeline 50 can also be the pipe of other materials, such as plastics Pipe etc..

As shown in figure 8, chopping wheel 31 includes rotary base 311 and disk cover 312, the lid of disk cover 312 is located at rotating disk bottom On seat 311, installation cavity is surrounded between rotary base 311 and disk cover 312, rotating disk 42 and movable claw 41 are arranged at installation cavity In, spacing hole is formed on the side wall of installation cavity, the one end in the axle center away from rotating disk 42 of movable claw 41 can be from spacing hole central diameter To stretching out.Chopping wheel 31 is divided into two, rotating disk 42 and movable claw 41 is easily installed, rotary base 311 and disk cover 312 can To play spacing effect, prevent rotating disk 42 and movable claw 41 from the situation of axial movement occurring.Spacing hole can limit movable claw 41 rotation so that movable claw 41 can only be relative to the radially direction movement of chopping wheel 31.

As shown in figure 8, the first drive mechanism 33 includes the first motor 333 and the first drive mechanism, the first motor 333 is fixed On chopping wheel 31, the first drive mechanism is connected between the output shaft of the first motor 333 and rotating disk 42,42 turns of driving rotating disk It is dynamic.Start the first motor 333, the output shaft rotation of the first motor 333 is rotated by the first drive mechanism driving rotating disk 42, turn Disk 42 is rotated and drives movable claw 41 to move along the radial direction of chopping wheel 31, and then movable claw 41 drives cutter 32 to turn along cutting The radial direction of disk 31 is moved, and pipeline 50 can be cut.In other embodiments, it is also possible to be not provided with the first driver Structure, is directly rotated by the driving rotating disk 42 of the first motor 333.
