Description

Pipeline bevel cut machine

The utility model relates to a kind of plant equipment-pipeline bevel cut machine to pipeline cutting, groove.

The pipeline of all kinds of different sizes need cut off pipeline also and weld behind the groove, so that weld is solid and reliable in laying and maintenance process.Currently used elder generation cuts with oxygen, again with the processing method of portable grinder or hand sander polishing finishing, it is low to exist efficient, ropy shortcoming, when the pipeline of repair and replacement oil transportation and combustible gas, owing to during portable abrasive machine and sander polishing finishing and thermal-flame during the oxygen cutting and the spark that splashes, very easily make residual oil and combustible gas breaking out of fire and explosion accident in the pipeline.

That the purpose of this utility model is to provide is a kind of good to pipeline cutting, groove crudy, and the efficient height does not produce spark, pipeline bevel cut machine safe in utilization.

The purpose of this utility model is achieved in that by arc sub-assembly 1 and connects and composes dismountable circulating type fuselage 2, locking device 14 is housed on the dismountable circulating type fuselage 2 and rolls guide wheel 3, be positioned at the gear ring 5 of dismountable circulating type fuselage 2 ends and roll guide wheel 3 and flexibly connect, power 9 by speed changer 8 and axle 16 make driving gear 4 drive gear rings 5 and on knife rest 10 rotate around pipe, cutter 11 is housed on the knife rest 10.

Both can also can connect between the described arc sub-assembly 1 with bolt 6 butt joints, overlap joint with connector 7.

Described gear ring 5 is dismantled and assembled forms, and dismounting combination place can be used bridging arrangement, also can use docking structure.

The garden week position of described gear ring 5 can be a spill, also can be convex.

On the described gear ring 5 a plurality of knife rests 10 can be installed, a knife rest 10 also can be installed.

Described knife rest 10 is provided with ratchet feed arrangement 13, the guide rail of knife rest 10 can be made the dovetail form, also can make rectangle.

Described power 9 can be used motor, also can be with air motor or oil motor.

The utility model compared with prior art has the advantage that crudy is good, efficient is high.Because the bevel cut process do not produce spark, so there is not the danger of fire and blast when using.Owing to adopt the dismounting combining structure, so easy to use, it is wide to be fit to scope.

The utility model will be further described below in conjunction with accompanying drawing.

As shown in Figure 1,1 pair of arc sub-assembly at one, is connected it with bolt 6, constitutes dismountable circulating type fuselage 2.Speed changer 8 is contained on the fuselage 2, and power 9 (can use motor, also can with air motor or oil motor) is installed on the speed changer 8, rolls guide wheel 3 and driving gear 4 and is contained on the axle 16, constitutes dynamical system.As Fig. 1 and shown in Figure 5, roll guide wheel 3 and be contained on the dismountable circulating type fuselage 2.Dismountable gear ring 5 as shown in Figure 6; Be combined with knife rest 10 it is connected together, versatilely gear ring 5 is connected the end of circulating type fuselage 2 by Fig. 1 and form shown in Figure 5 by rolling guide wheel 3, the bevel cut machine that assembles enclosed be enclosed within pipe (seeing the pipe G shown in Fig. 1 double dot dash line) and push away the fully position of bevel cut, for very long pipe, or when the maintenance pipeline, the position ring that can directly the bevel cut machine need be processed at pipe is assembled around pipe, after assembling, tighten the screw rod 15 of the locking device 14 that is located on the fuselage 2 respectively, locking device 14 stretches out to pipe, can securely fuselage 2 be fixed on the pipe.Turn on the power 9, through speed changer 8, axle 16, driving gear 4 is rotated, and drive gear ring 5 and rotate around pipe, the knife rest 10 that is installed on the gear ring 5 also rotates around pipe thereupon.In rotation process, as shown in figures 1 and 3, be arranged on the pin 12 that the ratchet feed arrangement 13 on the knife rest 10 is installed on the circulating type fuselage 2 and stir, make the cutter and the groove cutter that are installed on the knife rest 10 do radially feed campaign, pipe is cut and the cold machining processing of groove simultaneously.

The utility model can locate to adopt the structure that connects with liner plate 17 shown in Figure 10 deciliter of gear ring 5, installs a knife rest 10 and cutter 11 another deciliter locating, and pipe is only cut or the processing of groove.Also can after finishing cutting processing, change a groove cutter again and carry out groove processing.Also can be two knife rests 10 as Fig. 1 with shown in Figure 6 be installed in deciliter locating of gear ring 5; Or combine deciliter locating to connect with Fig. 9 or form shown in Figure 10, and two knife rests 10 and cutter 11 are installed in the position shown in the double dot dash line of Fig. 1 gear ring 5, just can finish simultaneously and cut and the processing of groove.Four knife rests 10 and four can also be installed simultaneously cutter 11 on gear ring 5, the working (machining) efficiency of its cutting, groove can be higher.

As shown in Figure 5, the spill that guide wheel 3 is complementary is made and is rolled at all positions, the garden of gear ring 5, so that gear ring 5 is connected the end of circulating type fuselage 2 versatilely.Also the garden of gear ring 5 week position can be made convex, the form that adopts flexible connection shown in Figure 7 to mate.

Constitute between the camber sub-assembly 1 of dismountable circulating type fuselage 2 can be shown in Figure 11,12 form with screw 6 butt joints or overlap joint.Also can form as shown in figure 13 connect with connector 7.Also can connect with the connector shown in Figure 15,16 7 as shown in figure 14, also can connect with bolt shown in Figure 180 as shown in figure 17 between the camber sub-assembly 1, constitute dismountable circulating type fuselage 2.

When power 9 adopted motor, preferred plan was to adopt the motor of end face type of attachment.If when adopting air motor, needing only compressed air (can be air compression station, engineering truck, air compressor.) pick on the air motor just passable with the tracheae of energy pressure-bearing.If when adopting oil motor, just pressure oil has been picked on the oil motor just with the oil resistant oil pipe of energy pressure-bearing.
