Detailed description of the invention

Below in conjunction with accompanying drawing, stress the realization of high interchangeability for DN100 steel pipe boundling, the structure of this buncher, principle of work and using method are described simultaneously.

See Fig. 1, pipe bunching device is made up of beam 1, positioning pipe 2 and secure component.The width of described beaming device is 2275mm, 25mm less of the interior width 2300mm of common transport trolley.

Beam 1 has upper beam and each two totally four of underbeam, all adopt No. 12.6 I-beam sections, to be parallel to each other layout at end face and bottom surface horizontal direction respectively, underbeam from bottom supporting by the orlop pipe 5 of boundling, upper beam is pushed down by the superiors' pipe of boundling from top, the beam of a top aligns placement with the beam of a below is parallel up and down.

Beam 1 parallel welding model in main body is the square tube of 50, and square tube goes up the positioning groove that proportional spacing is distributed with positioning tube along its length, as a kind of positioning pipe 2 of form.

See Fig. 2, the positioning pipe 2 be distributed between two-layer pipe also adopts square tube, separate each layer in location by boundling pipe, at every layer of two positioning pipe that is arranged in parallel, the upper and lower surface of every root positioning pipe is distributed with the positioning groove of positioning tube along the length direction proportional spacing of pipe, and the spacing between described positioning groove is consistent with the spacing of the positioning groove on beam.

Positioning groove on the positioning groove 21 of the positioning pipe 2 on beam and interfix pipe is all the arc-shaped slot outputed on pipe welds arc and is formed, and the radian of arc is 120 °, in positioning groove, slipmat is housed.

The spacing of the pipe 5 after boundling is consistent with the requirement of 2004-100/150 hard pipeline distributing vehicle, and make whole beam tube after boundling to be directly lifted on distributing vehicle, a set of buncher positioning pipe has 14.

For improving intensity and being convenient to form fastening and lifting, the derby that wide 74mm is welded at the two ends of beam 1 respectively forms fastening and hoisting structure 4, concrete structure is on derby, cut out the suitable groove of size (breach), and processing is used for the depression platform of upper spring packing ring and nut, is convenient to be connected with pull bar.Derby separately opens a gap in the inner part for lifting.

Secure component 3 comprises four pull bars 31 and is assemblied in the clamp nut assembly 32 at pull bar two ends, is connected between the fastening and hoisting structure in the termination of beam, tension beam.Clamp nut assembly is by a first spring washer, it connects a nut, then uses an identical spring washer, finally again with two packing ring double nuts structures that an identical nut is formed, can improve fixing reliability.For prevent nut get loose and packing ring, nut loss, devise anticreep screwdriver bit 33 at pull bar two ends.After other completion of processing of pull bar, screwdriver bit process after two ends all form two packing ring, double nuts structure, then is carried out in pull bar two ends by upper spring packing ring, One-way nut, spring washer, One-way nut respectively at its two ends.

POL equipment 2004-100/150 hard pipeline distributing vehicle is equipped in sizing has stricter requirement to the horizontal location of steel pipe and vertical alignment, otherwise the steel pipe after boundling can not arrive the correspondence position of distributing vehicle smoothly, therefore the design will make device have the feature of registration and uniform pressure distribution.For this reason, this device adopt on beam and positioning pipe, all process internal diameter and outer diameter of steel pipes identical location arc, formation positioning groove, make location arc and pipe closely sealed, utilize the 120 ° of central angles be of moderate size, complete every a line location accurately and reliably in the horizontal direction.Simultaneously with the positioning groove on the beam of below for benchmark, utilize gravity to complete alignment that each is listed in vertical direction.Beam and horizontal location pipe two one, reach accurate positioning function jointly.The positioning groove design of this device, makes steel pipe contact with positioning groove forming surface, increases area of contact, reduce stress, make pressure be distributed in contact position more equably, uniform pressure distribution, the pipe shaft distortion effectively preventing pressure from causing; Location arc fastens rubber pad, makes pipe have good buffering, and increase friction, the horizontal and vertical slippage of pipe can be avoided.

For positioning pipe 2, see Fig. 2, the main body of positioning pipe is the square tube of length of side 50mm, and its length gets 2206mm, just aligns with about pipe shaft, not only reliable but also neat appearance.Its length of the location arc of positioning groove 21 gets 80mm, and analogy pipe range goes out 30mm, and the 15mm that two ends respectively have more mainly reserves for fastening rubber pad, also increases the area of contact of steel pipe and rubber pad simultaneously, reduces pressure.

Compared with former buncher, the structure of beam has very large change, and upper beam, underbeam all adopt identical structure.See Fig. 3, Fig. 4, the two ends of beam are designed with fastening and hoisting structure 4, formed by the derby of a long 200mm, wide 74mm, thick 126mm and the end machining of No. 12.6 I-beam sections, the One-way nut on clamp nut and pull bar selects the thicker hexagonal nut of the thick 30mm of internal diameter 20mm adapted 30mm spanner.

See Fig. 3 and Fig. 4, beam 1 adopts I-beam section, total length from before 2088mm become 2275mm, on it, leg 11 and waist 12 are processed, and lower leg 13 retains always.Carried out more processing to the derby increased in addition, derby has 118mm length to stretch into the inside of steel I-beam 1, and on afterbody shape slope 45 at 45 °, is not only more convenient for and the welding of I-beam section, is also conducive to preventing stress from concentrating.Lifting breach 41 on derby is processed as the arc of radius 53mm in cable wire junction, increase area of contact, make distribution of stress evenly, lifting breach self also turn fillet, avoid stress concentrate.

Particularly, two are processed with to the termination of steel I-beam 1: be first cut at Width, the upper leg 11 of I-beam section and waist 12 cut 82mm length, but retains leg 13, for clamp nut degree of tightness operation leaving space, simultaneously for derby add reserved location.Section 2 processes the U-lag mouth that a width is 17mm (3mm less of pull bar diameter), picking and placeing for pull bar to the lower leg stayed, and prevent pull bar with rotation during nut tightness adjusting.

Four are mainly contained to the processing of the derby as fastening and hoisting structure 4: be first to bottom surface processing on it, make it just to fit with the surface of the leg up and down of steel I-beam; Then three processing is symmetrically carried out at length direction (x to) again about xoy plane: the groove 44 being once the long 118mm of processing one, wide 5mm (identical with the waist thickness of No. 12.6 I-beam sections), then cutting a cross section in its termination is the triangular prism of isosceles right triangle, form 45 ° of slopes 45, concentrate to reduce stress; Another time processes at the other end U-lag 43 that a width is 17mm (3mm less of pull bar diameter), this U-lag 43 is positioned at directly over the U-lag mouth of leg on I-beam section, one is used from picking and placeing of pull bar, and prevents pull bar with rotation during nut tightness adjusting; Be for the third time the upper surface of derby process one with the semi-circular concentric in U-lag, circular pit 42 that the degree of depth is suitable, for upper fastening nut assembly, this circular pit has the vital function preventing from causing pull bar landing because of nut loosening.After steel I-beam and derby process, suitably weld at their touching positions, make it into as a whole, can further improve mechanical strength.

See Fig. 5, Fig. 3, Fig. 4, walk the problem of the beam of top for solving the time shift of mechanization stringing, this device spy is provided with in the downside of each termination of beam the anticreep block 34 that two are hung away beam.This anticreep block is made up of the derby of long 28.5mm, wide 10mm, high 30mm, and be welded in the outer surface of leg under I-beam section, its size and position make it to boundling without any impact.

After pull bar is withdrawn, the beam hanging away top has three kinds of methods: as shown in Figure 5, one is by the U-lag of lifting-steel-rope 6 through beam termination, utilize the combined action of U-lag and an anticreep block that cable wire is not skidded off, other one end of beam processes equally, utilizes homonymy anticreep block, then under the effect of deadweight, beam is stably lifted can rotate about 90 ° in lifting process after, is then hung away, recommendation the method.The second is in the above-mentioned methods, uses diagonal line (heteropleural) link stopper instead, then because beam is in astable state of equilibrium, may occur rotating, not recommendation which.The third is that utilize the breach that the registration arm on two anticreep blocks and beam is formed, other one end of beam processes equally, and beam is also in astable state of equilibrium by lifting-steel-rope through the both sides of beam termination, may occur rotation, also not recommendation which.

See Fig. 6, be for preventing pull bar from getting loose with nut assembly when rotation during nut tightness adjusting and transport to the processing of pull bar 31 end.Be processed into wide 12mm, two of long 120mm symmetrical planes parallel to each other in the side of pull bar upper and lower, two interplanar distances are 16mm, and 1mm less of the width (17mm) of U-lag, while preventing pull bar with nut rotation, is convenient to picking and placeing of pull bar.After the first-class spring washer in termination and nut, then carry out screwdriver bit process, form anticreep screwdriver bit 33, make pull bar, spring washer, nut form integral structure, to prevent getting loose of nut in the loss of packing ring, nut and boundling steel pipe transmission process.

This beaming device, by design symmetry, achieves block construction minimized.Upper beam, the underbeam Curve guide impeller generally adopted in other beaming devices is a kind of version by the first, underbeam can be exchanged with general, and can become main bearing member in turn, can increase the service life of buncher; It two is that pull bar upper and lower side is designed to a kind of version, and do not distinguish up and down, Tiebar structure simplifies further.The result of such design makes component processing become simpler on the one hand, can improve the interchangeability of parts of the same race on the other hand, bring convenience to use.

This beaming device is only made up of three kinds of parts, can not need in warehouse or field with manpower or machinery, pipe to be assembled into bundle easily by miscellaneous equipment, significantly can alleviate the labour intensity of the processes such as steel pipe storage, carrying, use, raise the efficiency.
