Referring to Fig. 1, the utility model is a kind of multifunctional pipe interface equipment, comprise that two are drawn back of the body body and wire rope, it is characterized in that drawing back of the body body by saddle-shaped drawing clamp 1, rubber plate 10, upper bar frame 2, lower bar frame 16, go up pulling block 5, lower drawing block 15, rack tube 4, tooth bar 7, gear 8, gear shaft 13, rocking handle 14, draw ear 12 and bolt draw bar 17 to constitute, wherein, upper bar frame 2 is welded on drawing clamp 1 top, lower bar frame 16 is welded on the bottom of drawing clamp 1, last pulling block 5 is placed in the recess of upper bar frame 2, and lower drawing block 15 is placed in the recess of lower bar frame 16; Rubber plate 10 and drawing clamp 1 bottom surface adhering junction; Rack tube 4 lower ends are provided with gear shaft 13, and gear 8 is fixed on the gear shaft 13, and rocking handle 14 is enclosed within on the gear shaft 13, and an end of tooth bar 7 is welded with and draws ear 12, and tooth bar 7 passes rack tube 4, and the wheel of its tooth and gear 8 is nibbled and closed the location; Rack tube 4 is located between drawing clamp 1 two side, is welded to connect with drawing clamp 1.Last pulling block 5 is cuboid, has two holes above, is used for the wire rope break-through; Lower drawing block 16 is cuboid, has two holes above, places the bolt draw bar 17 of band nut 20 in the hole.

Tooth bar 7 is microscler tooth bars, has positioning hole 11 on the tooth bar 7, in order to insert latch 3.Tooth bar 7 can forward and reversely be installed in the rack tube, is applicable to two-way pipeline in succession.

Lower bar frame 16 is angle Supports, and front plate is provided with two microscler through holes of opening, is used to place bolt draw bar 17.

In order to reinforce, between the two side of drawing clamp 1, also to be provided with and to strengthen pipe 9.

Use in order to tear pipe open, also be welded with in the outside, two side of drawing clamp 1 and draw ear 12.

Referring to Fig. 2, Fig. 3, during use, at first place two drawing clamps in the bilateral symmetry of pipe 25, last pulling block 5 is placed in the recess of upper bar frame 2, by last wire rope 6 two interface equipments is connected together; Lower drawing block 15 is placed in the recess of lower bar frame 16, with two following wire rope 19 by bolt draw bar 17 with the interface equipment lock ring on body.Following wire rope 19 elbows are firm with wire rope clip 18 cards.By different functions, promptly take over, rectify a deviation, tear open pipe and narrate respectively below:

Referring to Fig. 4, take over operating procedure, both sides are welded with the end that the adapter arm-tie 22 that draws ear is placed on pipe 25, two sides are respectively with a wire rope 21, one end of wire rope 21 is fastened drawing on the ear at adapter arm-tie 22, (tensioning tool can be a jack for the other end of wire rope 21 and tensioning tool 23, the palm cucurbit, very heavy drawing or oil hydraulic cylinder) connect, the other end of tensioning tool 23 is connected with the ear that draws on the tooth bar 7 by wire rope, after being ready to, elder generation's rotation crank 14, this hour rack 7 moves, and with wire rope 21 tensions, inserts positioning hole 11 with latch 3, its effect is to overcome the wire rope amount of deflection, operation is left again, the tensioning tool 23 on right side, pipe will move forward, and finish the butt joint of pipeline.
