Abstract
The invention relates to a steel wire rope with long service and great safety performance. The steel wire rope has a main rope (1) and is characterized in that the main rope (1) is a six-strands steel wire rope having a hemp core in the middle; the upper and lower ends of the main rope (1) are divided into different strands and bend to form annular buckles (2); the annular buckles (2) are inserted into the middle part of the main rope (1) to orderly form a first-time forward-direction insertion part and a second-time negative-direction insertion part; the hemp core is cut off from the insertion start end; six scattered strands are formed during the insertion; the tail end of the second-time negative-direction insertion part is provided three re-weaved scattered strands; the three re-weaved scattered strands are not adjacent to each other; and the three re-weaved scattered strands are then re-weaved into the main rope (1). The steel wire rope with the long service life and great safety performance is advantaged by free damage to the steel wire rope end, exposure resistance and long service as well as great safety performance.
Description
Technical field
The present invention relates to the good rope rig of high safety performance in a kind of service life and manufacture method thereof.
Background technology
Traditional end being spliced rope rig is directly exposed to outside, and general way adopts the mode of oxygen cutting to remove the steel wire exposed, and can damage steel wire rope like this, reduce service life; Good way is the mode adopting machinery to remove, as the steel wire exposed is removed by crop(ping)shears.In use, the steel wire exposed can hurt the hand of user to the rope rig produced with upper type, causes certain potential safety hazard.Therefore seek a kind of steel cord ends can not damage the good rope rig of the high safety performance in service life that also can not expose and manufacture method particularly important.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the rope rig that the high safety performance in service life providing a kind of steel cord ends to damage also can not to expose is good and manufacture method thereof.
The object of the present invention is achieved like this:
The good rope rig of high safety performance in a kind of service life, it comprises main rope, described main rope is middle six strand steel wire ropes with hemp core, the other capitiform of the equal share split in the described upper and lower two ends of main rope becomes latch closure, described latch closure carries out being spliced formation forward successively to main rope middle part and is spliced part and is oppositely spliced part twice, hemp core be spliced initiating terminal cut from, six roots of sensation broken lot is formed when being spliced, oppositely be spliced portion distal end in second time and the broken lot that three are returned volume is set, three are returned the broken lot compiled be non-conterminous three broken lots mutually, and three are returned the broken lots compiled and return and compile extremely in main rope.
The manufacture method of above-mentioned rope rig comprises the following steps:
Step one, choosing rope picture point
Select middle six strand steel wire ropes with hemp core, measuring distance size L1, L1 at first in the end of steel wire rope is other head section start, and measuring second point distance size L2, L2 is other head termination, draws a mark at first place and second point place respectively;
Step 2, share split
In one end share split of steel wire rope, be divided into two groups of three stranded ropes, hemp core and one group of three stranded rope are divided into same group, and share split position is to second point place;
Step 2, other head
Start to work out latch closure in one end of steel wire rope, two groups of three stranded ropes carry out other head first position, and other head forms latch closure to second point position;
Step 3, broken lot remove hemp core
The latch closure of steel wire rope is fixed on a stiff end of bench vice, the suspension hook that top walked around by main rope is fixed on another stiff end of bench vice, above latch closure, two groups of three stranded ropes are carried out broken lot, form six roots of sensation broken lot and a hemp core, hemp core albert lays rotation along with hammer drill, make hemp core screw on main rope lay pitch, then hemp core is cut from main rope;
Step 4, forward are spliced
By six roots of sensation broken lot respectively from just twisting with the fingers to being upwards spliced one axial cord;
Step 5, first time are oppositely spliced
By six roots of sensation broken lot respectively from reverse lay two strands of axial cords to being upwards spliced;
Step 6, second time are oppositely spliced
By six roots of sensation broken lot respectively from reverse lay two strands of axial cords to being upwards spliced;
Step 7, time volume
By three non-conterminous broken lots respectively to compiling next time;
Step 8, end portion treatment
Adopt crop(ping)shears to wipe out on the broken lot head of six roots of sensation broken lot, then adopt trimmer shaping at haircut position, now the broken lot head of six roots of sensation broken lot is protected in main rope inside and does not expose.
Preferred as one, above-mentioned rope rig manufacture method concrete steps are as follows:
Step 4, forward are spliced
Define the upper six strands of clockwise directions of main rope and be respectively A stock, B stock, C stock, D stock, E stock and F stock, six roots of sensation broken lot after definition broken lot is respectively I stock, II stock, III stock, IV stock, V stock and VI stock clockwise, now on main rope bottom one be A stock, six roots of sensation broken lot bottom one be I stock;
By six roots of sensation broken lot respectively from just twisting with the fingers to being upwards spliced one axial cord;
4.1, I stock is passed below A stock,
4.2, II stock is passed below B stock,
4.3, III stock is passed below C stock,
4.4, IV stock is passed below D stock,
4.5, V stock is passed below E stock,
4.6, VI stock is passed below F stock;
Step 5, first time are oppositely spliced
By six roots of sensation broken lot respectively from reverse lay two strands of axial cords to being upwards spliced;
5.1, VI stock is passed below A stock and B stock,
5.2, V stock is passed below F stock and A stock,
5.3, IV stock is passed below E stock and F stock,
5.4, III stock is passed below D stock and E stock,
5.5, II stock is passed below C stock and D stock,
5.6, I stock is passed below B stock and C stock;
Step 6, second time are oppositely spliced
