The invention relates to means of manufacturing products rigging of steel ropes, in particular, to devices for making Oganov and spletna lifting straps used for the execution of salvaging and underwater engineering works.

Known rigging tools for making slings, containing straight and bent swiki various designs intended for cultivation of the strands of the rope (the formation of "lantern") in place of punching.

Preparatory work for the dressing's fire (loop) is the melting of the end of the rope strands on a certain length and imposing on each strand brands. Manufacturer's fire lead by compressing the strands of the rope through one strand at two downhill or against the descent rope. Prepared end of the cable, bend it, leaving the desired size of the loop, and loose strands applied to the rope in the place where you expect to start punching. Three strands running places on top and three on bottom of the indigenous end. If the cable is thick, it is about the brand of running late to take the rope caballi. Tamping the fid begin under three strands that are on top. The first running of the lock should be chosen so that it does not twist the chassis end. Then punch the fid from the same location under two strands and through this hole the second strand lying nearby. Then about the more from the same place fid under one strand and pass it the first leftmost strand. After that, the Windows turn 90 degrees. broken locks up and absolutepath musceles or mallet, so he came down to the brand. Then the Windows again lay flat on the reverse side.

Further, at the side facing broken strands, punch fid in the place where you are coming from the first three strands running, and pass in this place the fourth running strand. Then fid punch for the fifth strands, which, like the first, breaking under one strand. The sixth section punch with the back of a radical strands, which are punched and the first running strand, in other words, the sixth running strand of radical served under which pierced first, and put it back in the direction of the fifth running of the strands.

The second punching begins with the first running strands, which is passed through one under two indigenous strands from right to left, if you look at splashing on the hinge side. That was not cool punch, turn the fid to the right, then skip the first running strand next to the fid, fid removed, and the lock turning from left to right. Then punch the second suspension strand through one radical under two indigenous strands, but for her the same way and the other running threads.

When the second perforation is completed, splashing obstuctive a mallet, turning the rope. The total number of punches to 4.5, and with a heavy load on the cable is 5.5.

PR is the manufacture of Windows, you must observe the correct tamping and even covering strands, and for the preservation of indigenous strands of his position (see, for example, Bobryk village T.N., Rigging rescue, M., Voenizdat, 1956, str-163, 183-187).

The disadvantage used in the above-described technology sweek is the greater complexity of manufacturing a sling, as all work is done manually.

A known machine for tabletki straps design CPCB MMF (project No. 3923).

The machine includes frame, on which the two vertical posts. One rack mounted on the bracket fixed clip to another clip for rotation about its own axis. The clamp rotates with a drive motor mounted in the frame of the machine.

The machine allows to mechanize the most time-consuming part of the process of making a sling - breeding strands of the rope (the formation of "lantern") in place of punching. However, the operation by the institution of the strands on the end of the rope between the strands in place of punching in the above-described technology of the Windows manually. In addition, the vertical arrangement of clamps complicates the operation of manufacturing slings, and a constant distance between the clamps reduces the range of diameters of steel ropes from which the sling is made as to the diameter of the rope depends on the length of the loop's fire (on the machine CPCB MMF Ave No. 3923 can Isrotel the address lines of the steel rope diameter up to 40 mm).

The closest analogue of the claimed invention is a device for the manufacture of slings that contains a frame, fixed and swivel clamps mounted on racks, and drive the rotary clip (SU # 103207, CL D07B 7/16, 01.01.1956).

The objective of the invention is to eliminate these disadvantages and improve the working conditions of workmen for the manufacture of slings, steel wire ropes.

The technical result of the invention is to simplify the manufacture of slings.

This technical result is achieved by the fact that in the known device for the manufacture of slings that contains a frame, fixed and swivel clamps mounted on the rack and the drive of the swivel clamp according to the invention is installed on the frame node pulling of the strands of the end of the rope, consisting of a drum with the drive wound on a cable drum of a small diameter with a self-locking grip on the end and clutch used for coupling and uncoupling the shafts of the drum and drive, and drive of movable clamp is made in the form of a worm gearbox with arms and hour fixed by the clamp is arranged to move along the guides of the frame and then secured in it.

New the essential features of the device are:

- availability of the site pulling of the strands of the end of the rope in razvedeny the strands;

- performance actuator movable clamp in the form of a worm gear with handles;

- presence on the frame rails to move the rack with a fixed clamp and clamps for locking.

These significant differences provide:

- ability to mechanize the operation of pulling the strands of the end of the rope in diluted strands, thereby eliminating manual labor;

- more precise fixation optimum position of the divorced strand, wherein the strand end of the rope will get a big kick out with less effort;

- manufacture of slings, steel wire ropes of different diameter.

Figure 1 shows a General view of the proposed device for the manufacture of slings.

Figure 2 shows a view of the device from above.

Device for the manufacture of slings made in the form of a horizontal frame 1, one end of which there is fixed hour 2 with swivel clip 3. Rotation of the clamp 3 is carried out using a worm gear 4 with the arms 5. At the other end of the frame mounted movable stand 6 with a fixed clamp 7. Hour 6 can move along the guide rails 8 of the frame 1. Fixing the movable rack 2 on the frame depending on the length of the loop of Windows provided with pins 9 inserted into the holes 10 in the guide 8 of the frame 1 and 6 hours. On the frame 1 also has a mechanism is rotaliana the loose strands of the end of the rope, which includes a self-locking grip 11 with a cable of small diameter 12, which is wound on the drum 13, resulting in rotation by means of motor 14. Between the drum and motor is mounted the Cam sleeve 15, which is intended for coupling and uncoupling the shafts of the drum and the motor.

The device is used as follows:

depending on the diameter of the rope from which the sling is made, move along the guides of the frame 1 the sliding rack 6 and fixed by pins 9;

- prepared to work the rope 16 is passed through the clamps 3 and 7, and then fix it in them. Using the knobs 5 rotate the gear 4 in the direction opposite to the direction of lay of the strands of the rope. While the strands of the rope start to separate from each other on the whole interval between the clamps, forming a "lantern" 17;

- loose strands of the end of the rope according to the technology's fire passed between the strands in the "lantern". Then self-locking gripper 11 capture one of the missing strands include the engine 14, which causes the rotation of the drum 13. The cable 12 begins to gather around the drum 13, carrying the missed strand. Upon reaching the missed strands the right place in the "lantern" with clutch 15 disconnect the shaft of the drum from the motor shaft. Wound the rope 12 from the drum 13, thereby returning the grip 11 in the original Polo is giving. Repeat this operation with another lock up until all strands of the end of the rope will not Protamine through the "lantern";

- after pulling all the strands rotate the gear 4 in the opposite direction. The rope 16 takes the former view. Then make swage "the lantern" and the imposition of benzele the treated area of the rope.

Feasibility advantage of the proposed device compared to adopted for the prototype known device structures CPCB MMF (No. 3923) is to reduce the amount of manual labor in the manufacture of slings and improve working conditions.

In the device according to this invention design documentation. The use of the invention it is possible in the manufacture of products made of steel ropes used in salvaging and underwater engineering and other works associated with the movement of various cargoes.
