[0030] The rivet 1 includes a strip plate 101 inserted between a plurality of sub-ropes 2. Both ends of the strip plate 101 are vertically fixedly connected to a limiting plate 102. The two limiting plates 102 and the limiting plates 102 form two receiving grooves for fixing the sub-ropes 2. A plurality of sub-ropes 2 are respectively placed in the two receiving grooves, and the number of sub-ropes 2 in the receiving grooves is equal.

[0031] Specifically, the steel wire is twisted around a rope core 201 with 9 steel wires 202, and 4 steel wires are twisted into sub-ropes 2, and then 4 sub-ropes 2 are twisted to the left, and the other 4 sub-ropes 2 are twisted to the right and arranged alternately; the 8 sub-ropes 2 are arranged neatly according to the lay length, and the seams of the sub-ropes 2 are opened using a conical tool. When the rivet 1 is inserted, the limiting plate 102 on the rivet 1 enters parallel to the sub-ropes 2 to facilitate passing through the seams of the sub-ropes 2. After the limiting plate 102 passes through the sub-ropes 2, it is flipped over so that all the sub-ropes 2 are distributed in equal numbers in the upper accommodating cavity and the lower accommodating cavity on the strip plate 101. At this time, the limiting plate 102 is perpendicular to each sub-ropes 2 to fully fix the sub-ropes 2; after the rivet 1 and the sub-ropes 2 are inserted, the actual width is 153mm, the actual thickness is 24mm, and the actual dimensional tolerance is (+6.9%, +0%), which meets the dimensional tolerance requirements of the length × width (±10%) of the flat steel wire rope section.

[0032] Furthermore, the lay length of the sub-rod 2 is 19 times to 21 times the diameter of the sub-rod 2 .

[0033] Furthermore, the sub-rope 2 is formed by twisting a plurality of steel wires.

[0034] Furthermore, the number of the steel wires is 4.

[0035] Furthermore, the steel wire includes a rope core 201 and a plurality of steel wires 202 , and the plurality of steel wires 202 are twisted around the outer wall of the rope core 201 .

[0036] Furthermore, the lay length of the steel wire is 8.5 to 9.5 times the diameter of the steel wire.

[0037] Furthermore, the number of the steel wires 202 is 9.

[0038] Furthermore, a protective layer is provided on the outer wall of the steel wire 202 .

[0039] Furthermore, the protective layer is a galvanized layer.

[0040] The utility model provides a mining rivet flat steel wire rope, the preparation steps are as follows:

[0041] Step 1: Install the sub-rods 2 side by side on the platform of the braiding machine in the order of left and right twist, and compact the sub-rods through the wire splitter, front pressure roller, and rear pressure roller. The model of the front pressure roller is selected according to the width of the flat rope + 5%, and the model of the rear pressure roller is selected according to the width of the flat rope + 10%;

[0042] Step 2: Design and process the standard parts of rivet 1, and require the surface to be hot-dip galvanized;

[0043] Step 3: Align the 8 strands of rope with 2 lay lengths and make sure the gaps are consistent;

[0044] Step 4, use the electric conical tooling of the braiding machine to open the seams of the 8 strands of sub-rope 2. When inserting and braiding, the two ends of the rivet 1 are horizontal, and the middle part is erected. The small height makes it easy to pass through the gap of the sub-rope 2, but the middle part is not firmly in contact with the sub-rope; after passing through, turn it 90° so that the middle flat part of the rivet 1 is firmly in contact with the sub-rope, and the two ends are erected to clamp the sub-rope 2, so that the sub-rope 2 and the rivet 1 are firmly combined together;

[0045] Step 5: Drive 4 rivets into each lay length in sequence to make the required rivet-fixed flat steel wire rope.

[0046] Embodiment 2:

[0047] Reference Figures 5 to 7As shown, the difference between this embodiment and the first embodiment is that one end of the strip plate 101 is vertically fixedly connected to the limiting plate 102, and the other end of the strip plate 101 is fixedly connected to the guide block 103, and the limiting plate 104 is slidably arranged on the guide block 103. The middle part of the limiting plate 104 is provided with a groove 105, and the limiting plate 104 is slidably connected to the guide block 103 through the groove 105; the limiting plate 102 is provided with two countersunk holes 108, and the two countersunk holes 108 are symmetrically arranged on the strip plate 101. On both sides of the plate 101, a pull wire 109 is passed through the countersunk hole 108, one end of the pull wire 109 is fixedly connected to a clamping block 107, one end of the pull wire 109 is limited by the limiting plate 102 through the clamping block 107, and the other end of the pull wire 109 is fixedly connected to a wire pressing bolt 110. The limiting plate 104 is provided with two through holes 106, and the through holes 106 are correspondingly arranged with the countersunk hole 108. The wire pressing bolt 110 passes through the through hole 106 and the wire pressing bolt 110 is threadedly connected with a clamping nut 111.

[0048] When in use, insert one end of the limit plate 102 with the guide block 103 into the gap of each strand of the rope 2 and pass through the rope 2. At this time, the limit plate 102 is perpendicular to the extension direction of each rope 2. After the insertion is completed, the guide block 103 extends out of each rope 2, the limit plate 2 104 is sleeved on the guide block 103, and the pull wire 109 with the pressure wire bolt 110 is passed through the countersunk hole 108 and the through hole 106 in turn and the pressure nut 111 is tightened. It should be noted that the pull wire 109 is a flexible steel rope with good tensile strength, and one end of the pull wire 109 is passed into the pressure wire The bolt 110 is inserted into the hole at the end thereof and is pressed and fixedly connected with a hydraulic tool. The pull wire 109 and the clamping block 107 are also pressed and fixedly connected with a hydraulic tool; each sub-rope 2 is limited in the receiving groove on the pull wire 109 and the limiting plate 102 to complete the fixation of the sub-rope 2. The structure in this embodiment is convenient for the insertion and fixation of each strand of the sub-rope 2, and the limiting plate 102 can be inserted into place in one step without turning 90°. At the same time, the setting of the pull wire 109 can prevent each sub-rope 2 from deflecting and escaping from the receiving groove, thereby further improving the firmness and reliability of the insertion of the sub-rope 2.
