Embodiment 1

[0018] A device for braiding main cable strands with two sets of forming pulls, such as figure 2 As shown, the device for weaving the main cable strands consists of a wire guide frame 1, a pay-off reel 2, a wire separation frame 3, a forming device Ⅰ4, a traction machine Ⅰ5, a forming device Ⅱ7, a traction machine Ⅱ8, and a wrapping machine 9 connected in sequence. , coil forming machine 10, a buffer zone HC is set between the tractor I5 of the first set of forming traction device and the forming device II7 of the second set of forming traction device; It is released from the wire reel 2, and is bundled into the cross-sectional shape of the main cable strand through the wire guide frame 1, the wire separation frame 3, and the forming device I4. Under the traction and clamping action of the traction machine I5, it enters between the traction machine I5 and the traction machine II8. buffer between HC;

Embodiment 2

[0023] A method for weaving main cable strands, which adopts the device for weaving main cable strands described in Embodiment 1, adopts two or more tractions, sets a buffer zone, and eliminates the phenomenon of inconsistent internal force of steel wires during the forming process , accumulate the internal error of the main cable strands in the buffer area to reduce the internal error of the main cable strands; the following is the device for weaving the main cable strands with two sets of forming traction devices described in Embodiment 1 Take an example to illustrate its specific approach.

[0024] like figure 2 As shown, the steel wire is released from the pay-off reel 2, passes through the wire guide frame 1, and enters the wire distribution frame 3. The steel wire is bundled and formed by the forming device I4 into the cross-sectional geometric shape of the main cable strand, and is driven by the tractor I5 to output to the buffer zone. HC, after the main cable strands...

Abstract

The invention discloses a device for weaving main cable threads. The device is a production line composed of a wire guide frame, a pay-off spool, a wire distribution frame, n sets of forming and dragging devices, a wrapping machine and a coiling machine which are sequentially connected. Each set of forming and dragging device comprises a forming device and a dragger. A buffer area is arranged between every two forming and dragging devices. A method for weaving the main cable threads includes that steel wires are released from the pay-off spool, and pass the wire guide frame, the wire distribution frame and a forming device I to be clustered to be in the shape of cross sections of the main cable threads; under dragging and clamping actions of a dragger I, the steel wires enter the dragger I and the buffer areas among the forming and dragging devices; the steel wires are output by a dragger N of the Nth set of forming and dragging device to the wrapping machine, finished main cable threads are formed after fixed-distance wrapping is performed, and rolling and coiling of the main cable threads are performed by the coiling machine; N satisfies the condition that 2< / =N< / =10. By the device and the method, internal force deviations among the steel wires and length deviations of the steel wires in the main cable threads can be reduced.

Description

technical field [0001] The invention relates to a device for weaving main cable strands and a method for weaving main cable strands. Background technique [0002] The current production of main cable strands usually adopts the factory prefabricated strand method (PPWS), and the equipment used is a sequentially connected wire guide frame, pay-off reel, wire distribution frame, forming device, traction machine, wrapping machine, and coiling machine. The general process of the production line is as follows: arranging several steel wire pay-off reels in the workshop, the steel wires are drawn from each pay-off reel, and the main cable strands are formed after passing through the wire guide frame, forming device, traction machine and wrapping machine. The wire strands are then coiled by the coil forming machine (see figure 1 ); during the whole process, due to the difference in the relative position between the wire pay-off reel and the forming device, there are differences in t...
