Specific embodiment

Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.

As depicted in figs. 1 and 2, the cutting equipment of the present embodiment includes support device and cutter device 30, support device packet It includes：Support device includes：Supportive body 11, radial structure, radial drive mechanism and driving structure, the supportive body 11 of supporting are used for In 50 inner support cutter device 30 of pipeline；Radial direction supports structure setting on supportive body 11, radially supports structure along support master Being stretched in the radial direction to support the inner wall of pipeline 50 for body 11, provides support in pipeline 50 for cutter device 30；It is radial to pass Structure setting is moved on supportive body 11 and supports structure with radial direction and is connect, driving of the radial drive mechanism in driving structure 12 Under, the radial structure that supports of driving is stretched along the radial direction of supportive body 11.Cutter device includes：Chopping wheel 31, cutter 32, radial transmission component and the first driving mechanism, chopping wheel 31 are rotatably supported on supportive body 11；Cutter 32 are set It sets on chopping wheel 31；Radial transmission component is arranged on chopping wheel 31 and connect with cutter 32, and radial transmission group Under the driving of the first driving mechanism 33, driving cutter 32 move part along the radial direction of chopping wheel 31.

Cutting equipment is placed on to the inside of pipeline 50 before cutting pipeline 50 using the cutting equipment of the present embodiment.It cuts When pipe cutting road 50, under the driving of driving structure 12, radial drive mechanism driving is radial to support structure along the diameter of supportive body 11 It is mobile towards the inner wall of pipeline 50 to direction, it is supported on the inner wall of pipeline 50 until radially supporting structure, at this moment cutting equipment It is supported on the inner wall of pipeline 50, then under the driving of the first driving mechanism 33, radial transmission component drives 32 edge of cutter The inner wall of the radial direction of chopping wheel 31 towards pipeline 50 is mobile, meanwhile, chopping wheel 31 drives cutter 32 to rotate, thus So that cutter 32 are contacted and are cut with the inner wall of pipeline 50.After cutting, under the driving of the first driving mechanism 33, The axle center of radial direction towards pipeline 50 of the radial transmission component driving cutter 32 along chopping wheel 31 is moved, cutter 32 with The inner wall of pipeline 50 separates, and then the radial structure that supports of driving is moved along the radial direction of supportive body 11 towards the axle center of pipeline 50 It is dynamic, it radially supports structure and is separated with the inner wall of pipeline, cutting equipment is taken out from pipeline 50.In this way in pipeline 50 Cutting equipment is placed in portion, and support device is that cutter device 30 provides support, and cutter device carries out pipeline from the inside of pipeline Cutting, not by the narrow space between pipeline and pipeline the case where, be adapted to pipeline and arrange intensive occasion, convenient for removing arrangement Wherein one of intensive pipeline, effectively overcomes and cannot be used for metal tube to the cutting equipment of cuts in metallic pipe in the prior art The defect that densely arranged occasion is cut.

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

Due to chopping wheel 31 cutting when be it is rotary, movable claw 41 can be 31 turns with respect to chopping wheel in order to prevent It is dynamic.In the present embodiment, movable claw 41 is limited on chopping wheel 31, is only capable of moving along the radial direction of chopping wheel 31. Movable claw 41 and chopping wheel 31 are rotated synchronously, can not be rotated relative to chopping wheel 31.As it can be seen that movable claw 41 are merely able to move along the radial direction of chopping wheel 31, and then cutter 32 can be driven mobile, cut to pipeline 50.

As shown in Figure 10, it is preferable that movable claw matable assembly includes：Turntable 42 and card slot 411, turntable 42, rotationally It is arranged on chopping wheel 31, the surface of turntable 42 is equipped with the first spiral salient 421；Card slot 411 is arranged on movable claw 41 And it is matched with the first spiral salient 421；First driving mechanism 33 is rotated by driving turntable 42, drives movable claw 41 along cutting 31 radial direction of turntable is mobile.First driving mechanism 33 drives turntable 42 to rotate, and the rotation of turntable 42 drives movable claw 41 along cutting 31 radial direction of turntable is mobile, and then movable claw 41 drives cutter 32 to move along 31 radial direction of chopping wheel, can be to pipe It is cut in road 50.In other embodiments, spiral groove can also be set on the surface of turntable 42, set on movable claw 41 There are multiple protrusions compatible with spiral groove.

Preferably, card slot 411 is multiple, and multiple card slots 411 are arranged along the moving direction interval of movable claw 41.It in this way can be with Guarantee that the movement of movable claw 41 is more stable, is also possible to prevent to skid off from turntable 42 since the card slot 411 on movable claw 41 is very few and The case where.

In the present embodiment, pipeline 50 is metal tube.Certainly, pipeline 50 or 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 turntable bottom On seat 311, installation cavity is surrounded between rotary base 311 and disk cover 312, turntable 42 and movable claw 41 are arranged at installation cavity In, limit hole is formed on the side wall of installation cavity, the one end in the axle center of the separate turntable 42 of movable claw 41 can be from limit hole central diameter To stretching.Chopping wheel 31 is divided into two, is easily installed turntable 42 and movable claw 41, rotary base 311 and disk cover 312 can To play the role of limit, preventing turntable 42 and movable claw 41, there is a situation where move axially.Limit hole can limit movable claw 41 rotation, so that movable claw 41 can only radially direction be mobile relative to chopping wheel 31.
