[0002] The wire rope compression rigging is a cable structure that is formed by pressing a sleeve on the rope end to form a ring for connection. The existing technology is to cut the wire rope after stress-free length and then insert and press it to form the ring.

[0003] Wire rope is an elastic structure, and there are often large errors when it is customized without stress, which makes it impossible to guarantee the length accuracy of the wire rope pressing rigging. In particular, when used in pairs, there are often different lengths, which makes the wire rope pressing rigging unusable or causes safety accidents during use. Utility Model Content

[0004] The utility model aims to design a length-fixing device for steel wire rope pressing rigging and solve the technical problem of ensuring length accuracy during the production and manufacturing process of the steel wire rope pressing rigging.

[0006] A device for fixing the length of a wire rope compression rigging comprises a pinhole, a marking platform, a pin, a connecting bracket, a screw, an adjustment platform, a wire rope compression rigging, a slider, a guide shaft, a handle, and an end bracket. The adjustment platform is box-shaped with an open top, containing the slider, guide shaft, and pin. The connecting bracket and end bracket support and fix the adjustment platform and the marking platform. The adjusting handle drives the screw to slide the slider, tightening the wire rope compression rigging and marking the required length.

[0007] The beneficial effects of adopting the above technical solution are:

[0008] The technical solution of the utility model is applied in the production process of wire rope pressing rigging, which can simply and conveniently complete the length determination work of the wire rope pressing rigging, improve product quality, has a simple structure, is easy to operate, and is easy to promote and use.

[0014] A device for fixing the length of a wire rope compression rigging comprises a hook hole 1, a marking platform 2, a hook pin 3, a connecting bracket 4, a screw 5, an adjustment platform 6, a wire rope compression rigging 7, a slider 8, a guide shaft 9, a handle 10, and an end seat 11. The adjustment platform 6 is a box-like structure with an open top, containing the slider 8, guide shaft 9, and hook pin 3. The connecting bracket 4 and end seat 11 support and fix the adjustment platform 6 and the marking platform 2. The adjustment handle 10 drives the screw 5 to slide the slider 8, tightening the wire rope compression rigging 7 and marking the required length.

[0015] A plurality of hook pin holes 1 are set on the calibration platform 2. The closest hook pin hole 1 is selected according to the required rigging length. The wire rope pressing rigging of any length can be measured. The length relationship between the wire rope pressing rigging 7 and the hook pin hole 1 is L=L0+(n-1)*A, where L0 is the distance between the hook pins 3 at both ends of the measurement, n is the pin hole number, and A is the distance between adjacent hook pin holes 1.

[0016] The handle 10 can be replaced with a counterweight or motor-driven tension; it is suitable for calibration and testing of metal and non-metallic ring-pressed rigging.

[0017] A method for fixing the length of a wire rope pressing rigging fixing device comprises the following steps:

[0018] Step 1: According to the process technology requirements, the two ends of the wire rope 14 of the initial measured length are respectively inserted into the pressing sleeve 13;

[0019] Step 2: The two ends of the wire rope 14 are braided to form a loop 12, and the pressing sleeve 13 remains loose and movable;

[0020] Step 3: Connect the wire rope pressing rigging 7 including the pressing sleeve 13 to the hook pins 3 at both ends. Place the hook pin 3 at one end on the slider 8 and the hook pin 3 at the other end on the hook pin hole 1 of similar length on the calibration platform 2.

[0021] Step 4: Adjust the handle 10 to drive the screw 5 to slide the slider 8, tightening the wire rope until the handle cannot be turned;

[0022] Step 5: Measure the distance L0 between the two end pins 3, compare it with the process required length L, and mark the deducted allowance near the pin hole 1;

[0023] Step 6: Adjust the pressing sleeve 13 near the hook pin hole 1 to the marked point, loosen the adjustment handle 10, and remove the wire rope pressing rigging 7;

[0024] Step 7: Repeat steps 2 to 6 above until the difference between the distance L0 between the two end hook pins 3 and the process required length L is less than or equal to ±2 mm;

[0025] Step eight, pressing the sleeves 13 at both ends of the wire rope pressing rigging 7 to form a qualified product.

[0026] The principle of the utility model is to rotate the screw by adjusting the handle, so that the matching slider slides and tightens the wire rope, thereby achieving the required length of the wire rope pressing rigging marked in the tensioned state, and finally repeating the test many times and pressing after meeting the required length.
