Abstract
Description
Technical Field
[0001] This utility model belongs to the field of safety maintenance technology for metallurgical lifting equipment, specifically relating to a quick reset device for a derailed wire rope of a metallurgical crane. Background Technology
[0002] In steelmaking production, the main coil wire rope of metallurgical cranes is prone to derailment and jamming due to stress deviation or mechanical vibration. Traditional handling methods have three major drawbacks: High reliance on manual labor: maintenance personnel must climb to dangerous high-altitude areas to manually adjust the wire rope; low efficiency: the average troubleshooting time exceeds 2 hours, severely impacting production continuity; and high safety risks: manual operation easily leads to crush injuries, and the reliance on auxiliary hooks poses a secondary accident hazard. Current technology lacks specialized tools for rapid, non-contact wire rope reset, necessitating the development of a safe and efficient solution.
[0003] In view of the above factors, a quick reset device for derailed wire ropes of metallurgical cranes is provided. It adopts a non-contact reset mechanism that uses mechanical traction to replace direct manual operation, thereby eliminating the risks of working at heights. Utility Model Content
[0004] The purpose of this utility model is to provide a quick reset device and application method for derailed wire ropes of metallurgical cranes, so as to solve the problems mentioned in the background art.
[0005] The purpose of this utility model is achieved through the following technical solution: a quick reset device for a derailed wire rope of a metallurgical crane, comprising a first positioning frame and a second positioning frame, wherein the first positioning frame and the second positioning frame are detachably connected.
[0006] Both the first positioning frame and the second positioning frame are symmetrical arc-shaped structures. Double-sided wing plates are fixedly provided on both sides of the first positioning frame and the second positioning frame, and symmetrical through holes are opened on the double-sided wing plates.
[0007] A limiting device is provided on the inner side of the second positioning frame, and the limiting device tends to be centrally symmetrical along the arc-shaped structure of the second positioning frame.
[0008] Furthermore, two sets of the limiting devices are symmetrically fixed along the width of the second positioning frame.
[0009] Furthermore, the limiting device is detachably connected to the inner wall of the second positioning frame.
[0010] Furthermore, the limiting device includes a support frame and rollers movably connected to the support frame, with both sides of the rollers rotatably connected to the support frame;
[0011] The circumferential surface of the roller is parallel to the inner wall of the second positioning frame.
[0012] Furthermore, the limiting devices are symmetrically inclined, and a wire rope accommodating space is formed between the two sets of symmetrically inclined limiting devices and the second positioning frame.
[0013] Furthermore, the two ends of the support frame are detachably connected to pressure plates, and the bottom of the pressure plates is provided with a limiting part.
[0014] Furthermore, support columns are welded vertically to both ends of the support frame along the inclined surface of the support frame, and pressure plates are fitted onto the support columns and fixed with nuts.
[0015] Furthermore, the limiting part is provided with an arc-shaped structure, and the limiting part extends into the space where the two sets of symmetrically inclined limiting devices are located.
[0016] Furthermore, the inner surface of the second positioning frame is provided with an anti-slip textured layer, which is formed along the inner wall of the second positioning frame and is a laser-clad tungsten carbide particle anti-slip layer.
[0017] A method for applying a quick reset device for a derailed wire rope on a metallurgical crane includes the following steps: The first and second positioning frames are arc-shaped clamps made of Q345B steel. The on-site operation involves confirming the derailed position of the wire rope, inserting the second positioning frame into the wire rope, installing the pressure plate, pre-tightening the bolts to a torque of 5 N·m, and then aligning the first and second positioning frames. A hook is fixed to the second positioning frame with a nut. The hook is a rod structure with a circular hole at the upper end and a screw structure at the lower end that passes through a positioning hole on the first positioning frame. A rope buckle connects the hook to the auxiliary hook. One end of the rope buckle is attached to the hook, and the other end is hooked to the crane's auxiliary hook. The auxiliary hook is slowly raised, and the wire rope automatically slides into the track groove for reset through directional traction. The rope buckle is kept taut, and the auxiliary hook is raised at a speed of 0.5 m / min. The movement trajectory of the wire rope is observed. After the wire rope enters the groove, the pressure is released, and the device is disassembled.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This utility model connects a rope buckle to a crane auxiliary hook at the other end. The rope buckle is made of tensile-resistant synthetic fiber rope with a diameter of 15mm and a length of 1.5 meters. Both ends are braided with closed rope loops. The auxiliary hook is operated to slowly lift the crane, and the steel wire rope is automatically slid into the track groove and reset through directional traction force.
[0020] This invention employs a non-contact reset mechanism, replacing direct manual operation with mechanical traction to eliminate the risks associated with working at heights. Attached Figure Description

[0032] In use, the double-sided wing plates 3 on the first positioning frame 1 are connected to the fixing rod 9 by a hinge. The fixing rod 9 is a bolt rod structure. The fixing rod 9 is engaged with the through hole 10 of the double-sided wing plate 3 on the second positioning frame 2 and locked with a nut.
[0033] The bottom of the double-sided wing plates 3 of the second positioning frame 2 is provided with a shallow groove structure for accommodating nuts to prevent the fixing rod from coming out during the lifting process.
[0034] To facilitate use, depending on the diameter of the wire rope, the limiting device 4 can be symmetrically arranged in one or two sets, with two sets of the limiting device 4 fixedly fixed symmetrically along the width of the second positioning frame 2.
[0035] The limiting device 4 is detachably connected to the inner wall of the second positioning frame 2.
[0036] In order to facilitate the limiting device to reduce the sway of the wire rope during hoisting in use, the limiting device 4 includes a support frame 5 and a roller 6 movably connected to the support frame 5. The two sides of the roller 6 are rotatably connected to the support frame 5.
[0037] The circumferential surface of the roller 6 is parallel to the inner wall of the second positioning frame 2.
[0038] The limiting device 4 is symmetrically inclined, and the two sets of symmetrically inclined limiting devices 4 form a wire rope accommodating space between the second positioning frame 2.

The on-site operation involves confirming the derailed position of the wire rope, inserting the second positioning frame into the wire rope, installing the pressure plate, pre-tightening the bolts to a torque of 5 N·m, and then aligning the first and second positioning frames. A hook is fixed to the second positioning frame with a nut. The hook is a rod structure with a circular hole at the upper end and a screw structure at the lower end that passes through a positioning hole on the first positioning frame. A rope buckle connects the hook to the auxiliary hook. One end of the rope buckle is attached to the hook, and the other end is hooked to the crane's auxiliary hook. The auxiliary hook is slowly raised, and the wire rope automatically slides into the track groove for reset through directional traction. The rope buckle is kept taut, and the auxiliary hook is raised at a speed of 0.5 m / min. The movement trajectory of the wire rope is observed.
