To lodzstatklal ggret - LPA and slalom / gov i-b) to weave: ix insufficient, b, resource and resource, calling another unexcited P) sadochka, and sasjpaici the blow block in the hull and scored in the ball, which gives 1 xx zdam It is superficial, which is exacerbated, but a good quality air intake is available (lack of filtrate and no spraying). In addition, the air breathing element, the sliding element, is rigidly fixed relative to the body, which contributes so much to an extremely strong pair of slaps - the floor is araiko. As a disadvantage, it was possible that the air in the BJSj.yxJno / .Bor TfleM element smolders opi / iy 1 core chip, which does not allow for a very long time and leads to a real efficient process.

The task was helpful, the job was from the west side of the device with the high efficiency of the process of destruction of the old pipeline, and, as a result, the high productivity of the process and the long life.

To solve the specified tasks in a country for a bouncy SHOW, pipelines containing a housing, a head with lies, and a pneumatic arm were struck with an anvil, an anvil and an anvil, an assortment, a different hole in the body cavity with a gap, and

A new pipe 4 is attached to the rear part of the rasirpytelnol head 4. An anvil o with an eye 6 is installed in the front of the housing I with an opening: w for slinging auxiliary pull cable. In the internal cavity of the housing 1 is placed with the possibility of movement along jcii the drummer 7, forming with the housing 1 the middle I and the rear of the chamber, and with the hollow of the pistons 10 and brought the inner cavity II to the inner chamber x2, which through the window 13 communicates with the k-shavuly 14 on the surface of the drummer 7.

An increase in friction is facilitated by air conditioning, including}: 1 liter TRG and injection of oil. Ronudpo grann nokel 3 rasiltelon 2 lay down crookedly 1p./phfodil in ormo lekno. the curve, the angle of the poli-catholite angle to the rozhucel grand and the ax is destroying the pipe in the case of the ore dp of the letra of its flange is 40 ° ...- t5J, and in the zone of the inner dsh-ilgera the pipe is breaking 15J ... 20 °. Pa destructive face of the knife is applied using, for example, welding, the material has increased hardness,

e.g. cjpMaiT. The cutting face of NMA is sharpened by an angle of 60 ± 10 °.

The device works as follows.

A winch cable is pulled through the old pipeline, the end of which is solved in the case 6. On the rear side of the expansion heads 2 they close the winding pipe 4, pre-securing the air dividing hose on the tail pipe nozzle 15. The ramp air enters the inner working chamber 12 and through the window 13 of the hammer 7 into the front chamber 8. Due to the difference in the area from the front 8 and the inside 12 chambers, the gadget 7 moves backward (p; to the drawing of FIG. 2 to the right). After the windows 13 have reached the trailing edge of the hollow piston 1C, the front cutter 6 will be exhausted through the groove 14, the openings 13 / rear chamber 9. holes in the ring 16 to the atmosphere. The air pressure in the inner Kaiviepe 12 impact 7 stops without impact and begins to move forward (according to the drawing of figure 2 - to the left) until the front edge of the hollow piston 1C passes through the window 13. After opening the windows 13, the striker 7 strikes the bolkon on the anvil 5, which is transferred to the yurpus 1 p on the expander head 2 with a chopping knife 3, which starts the chopping process. The sealing pipe has not absorbed sealing material (cg. CxeLiy ииг.З). Here, the angles are tangent to the profile of the destroyed faces of the nosei-i to the smallpipe of the pipe being destroyed, namely: at the point of contact in the flange zone /, otf-iQ ... 45, and in the inner zone

iv axis paspyjaoMOji pipe order ./ (LO.. .20 (si. 7), this lead to

toglu, that at first the destructive face of the bed does not touch the collar of the destructive pipe, but the sealing material. With its considerable viscosity and elasticity, instead of destroying the flange, the jammed head collapses, self-braking occurs, which leads to a significant increase in the force applied to the head, and then to the cessation of movement.

Thanks to the lemma: the profile of the cutting edge i can be avoided. It will be possible to achieve the damages of the skrjuktpnvnispnp process due to. N n i cutting edges of the material are more full of hardness, nachchdler hard alloy type sorlalt11 and Sharpening of the ground face under the globes 1x 60 J + 10 ° (yl. Jiir, 4 ... 6).

VdKiu obrgzol, due to the claimed combination of principles, it will be possible to increase the greenness of the pipe greening process to CO / o and the higher resource, air, powder, and gas with oU de 2CO, raic by A. The tests of an experienced eraser were performed. The installed irolon-N will be able to clean the shafts when:, dor1shzatsd1: .1e1 is prepared for devices of this type, which will significantly reduce costs.
