Description

Technical Field

[0001] This utility model relates to a special tool for handling wire ropes coming out of the groove, belonging to the technical field of crane equipment in the metallurgical industry. Background Technology

[0002] In the metallurgical industry, molten metal cranes are critical equipment in the process flow. Occasionally, operational errors can cause the wire rope to slip out of the pulley groove. Previously, handling such problems required cutting a 200mm notch on one side of the pulley's edge with an oxy-acetylene torch. The wire rope was then inserted through this notch into the groove, and ∮10mm threaded steel bars were welded across both sides of the pulley's edge to block it. An ∮8mm traction wire rope was then attached to the threaded steel bar. An 8# iron wire threaded along the groove was used to pull the traction wire rope to the other side. On the other side, the traction wire rope was hooked onto a secondary hook. The lifting secondary hook, through the traction wire rope, caused the pulley to rotate, forcing the wire rope back into the groove. Finally, the cut-off edge was welded back in place. This process required welding and oxy-acetylene torches, was cumbersome, time-consuming (up to 2 hours), and carried the risk of cutting the wire rope. Utility Model Content

[0003] The purpose of this utility model is to provide a special tool for dealing with wire rope slippage from pulleys, which can conveniently and quickly handle the fault of wire rope slippage from pulleys without damaging the wire rope, thus solving the problems existing in the background art.

[0004] The technical solution of this utility model is:

[0005] A special tool for handling wire rope unloading from a groove includes a U-shaped clamp, a lead screw, a hook, a flip bracket, a nut, and a bushing. The U-shaped clamp is a single piece, while the lead screw, hook, flip bracket, nut, and bushing are each in pairs. The flip bracket is an integral structure welded from a central support ring and two trunnions on both sides. The lead screw moves through the central support ring. Nuts are welded to the hooks and connected to the lead screw. Bushings are welded to both sides of the U-shaped clamp. The bushings on both sides of the U-shaped clamp are fitted onto the trunnions in the flip bracket. The overall arrangement is symmetrical.

[0006] The spacing between the two sides of the U-shaped card plate matches the width of the wheel rims on both sides of the pulley.

[0007] The inner diameter of the intermediate support ring in the flip bracket is matched with the size of the lead screw.

[0008] One end of the lead screw is hexagonal, and the length of the lead screw matches the distance from the outer edge of the pulley to the center of the wheel hub process hole.

[0009] The hook's opening width is greater than the thickness of the pulley hub.

[0010] When dealing with the problem of wire rope coming out of the groove using this utility model, the wire rope is placed in the U-shaped clamp on one side of the pulley plate, and the two hooks are hooked into the process hole of the pulley plate hub. One end of the wire rope is pressed into the groove by tightening the screw. The other side is connected to the process hole of the pulley plate hub by a hand chain hoist. Pulling up the hand chain hoist causes the pulley plate to rotate, which in turn pulls the wire rope into the groove.

[0011] The beneficial effects of this utility model are: it can conveniently and quickly handle the fault of wire rope coming out of the pulley groove, and can control the fault handling time within 30 minutes, reduce hot shutdown, and will not damage the wire rope. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.

[0018] See attached document Figure 1-4 A special tool for handling wire rope unloading from a groove includes a U-shaped clamping plate 1, a lead screw 2, a hook 3, a flipping bracket 4, a nut 5, and a bushing 6. The U-shaped clamping plate 1 is a single piece, while the lead screw 2, hook 3, flipping bracket 4, nut 5, and bushing 6 are all in pairs. The flipping bracket 4 is an integral structure welded from a central support ring 8 and two trunnions 7 on both sides. The lead screw 2 moves through the central support ring 8. The nut 5 is welded to the hook 3 and connected to the lead screw 2. The bushing 6 is welded to both sides of the U-shaped clamping plate 1. The bushings 6 on both sides of the U-shaped clamping plate 1 are fitted onto the trunnions 7 in the flipping bracket 4. The overall arrangement is symmetrical.

[0019] In this embodiment, refer to the appendix Figure 1-4 The special tool for handling wire rope unloading includes: U-shaped clamp 1, lead screw 2, hook 3, flip bracket 4, nut 5, and bushing 6, wherein:

[0020] The U-shaped clamp 1 is made of 4mm steel plate, and the inner distance between its two sides is equal to the width of the wheel rim on both sides of the pulley plate 10. The U-shaped clamp 1 is provided with bushings 6 on both sides for connecting the flipping bracket 4. The U-shaped clamp 1 has notches on both sides, which can enable the flipping bracket 4 to flip at a certain angle in the notches, so that the hooks 3 on the lead screw 2 can be smoothly hung into the process hole 11 of the pulley plate hub.

[0021] There are two lead screws, each with a specification of M12*1.75. One end of each lead screw is hexagonal and used for screwing. The length of lead screw 2 is equal to the distance from the outer edge of pulley plate 10 to the center of the hub process hole.

[0022] Hook 3 consists of two pieces, made of ∮10mm round steel. The width of its hook opening is 5mm larger than the thickness of the pulley hub. M12*1.75 nuts 5 are welded onto hook 3 to connect to lead screw 2.

[0023] The flip bracket 4 consists of two parts, which are welded together by the middle bracket 8 and the two trunnions 7. The inner diameter of the middle bracket 8 is ∮14, which allows the lead screw 2 to move freely inside the bracket 8.

[0024] The operation process is as follows:

[0025] When dealing with the problem of the wire rope coming out of the groove, use this special tool to attach the wire rope 12 to one side of the pulley plate 10, hook the hook 3 into the process hole 11 of the pulley plate, tighten the screw 2 to press the wire rope 12 into the groove of the pulley plate 10, suspend a hand chain hoist above the other side of the pulley plate 10 and connect it to another pulley plate process hole 11, pull up the hand chain hoist to make the pulley plate 10 rotate 180° around the pulley shaft 9, and finally make the wire rope completely enter the groove.

[0026] This utility model patent is applicable to handling the problem of wire rope slippage from the groove in the moving pulley block of a molten metal crane. The moving pulley block consists of multiple pulley plates arranged axially, and the pulley block is equipped with a fixed pulley cover. The gap between the pulley cover and the edge of the pulley plate is smaller than the nominal diameter of the wire rope. For ease of illustration, the pulley cover has been deliberately removed from the figure, and only a single pulley plate is shown.
