Description

Technical Field

[0001] This utility model relates to the field of electromagnetic cranes, and in particular to a cable guiding device. Background Technology

[0002] In the new steelmaking process of the Special Steel Division, eight magnetic chucks in the scrap steel section are responsible for key operations such as unloading, loading, and dumping scrap steel required for electric arc furnace production. Due to the tight production schedule, the magnetic chucks operate at extremely high rates, leading to significant problems with the original fixed guide frames. Frequent swaying of the cables during hoisting easily causes friction with the guide frames, resulting in jamming. After prolonged operation, the cable sheaths wear down and even break due to continuous friction, affecting not only the reliability and stability of the equipment but also potentially causing sudden shutdowns, severely restricting production efficiency and increasing safety hazards. Furthermore, frequent cable maintenance and replacement result in high operating costs, hindering the company's efforts to reduce costs and increase efficiency.

[0003] Currently, most guiding mechanisms on the market are rigid and fixed designs. Due to their structural limitations, they are difficult to adapt to the high-intensity, high-frequency working environment of gantry cranes, especially under dynamic cable swinging conditions, where they cannot provide flexible guidance, exacerbating frictional losses. Although some improvement solutions attempt to use sliding pads or lubrication structures, they still cannot effectively solve the wear problem under high-load, high-frequency conditions.

[0004] Therefore, there is an urgent need for a simple and reliable rolling guide solution that can reduce cable friction resistance and improve durability, thereby ensuring the long-term stable operation of the magnetic crane, reducing maintenance workload and production costs. Utility Model Content

[0005] This utility model provides a cable guiding device that solves the problem that existing devices cannot provide flexible guidance under dynamic cable swinging conditions, and are prone to friction with the guide frame, thus causing jamming.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cable guiding device includes: a U-shaped frame, including two side arms and a top crossbeam, forming an upper and lower running channel for the cable; a rolling welded pipe, which is inserted through the two side arms and the top crossbeam of the U-shaped frame, with a 1-2mm gap reserved between the rolling welded pipe and the U-shaped frame to allow the rolling welded pipe to rotate freely; and a fixed base, welded to the bottom of the U-shaped frame, for fixing the device to the cover plate of the trolley on the cable lifting path.

[0008] Furthermore, the U-shaped frame is made of round steel bent and welded.

[0009] Furthermore, the outer diameter of the round steel bar is 2 mm smaller than the inner diameter of the rolling welded pipe to avoid jamming of the welded pipe and limit its radial wobble.

[0010] Furthermore, the surface of the rolling welded pipe is covered with a PVC flexible tube to absorb the impact force of the cable swinging.

[0011] Furthermore, the U-shaped frame is fixed to the trolley cover plate by flange bolts, and its center line is aligned with the cable reel and the cable movement trajectory.

[0012] Furthermore, the cable passes through the middle of the U-shaped frame, allowing for a natural drooping arc.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention significantly reduces cable wear and breakage, extending its service life by more than 50%. At the same time, it has a simple structure, low manufacturing cost, and requires no electric drive. It is suitable for high-frequency vibration and large-amplitude lifting conditions, and is easy to maintain.

[0015] This system enables the unloading and loading of scrap steel by eight disk cranes in the new steelmaking area of ​​the Special Steel Business Unit, extending the service life of the disk cables and reducing the impact on production. Attached Figure Description

[0024] This utility model provides a technical solution: a cable guiding device, such as... Figure 1 As shown, it includes a U-shaped frame 1, which is made of Φ20mm round steel bent and welded, including two side arms 11 and a top crossbeam 12, forming the upper and lower running channels of the cable 5;

[0025] The rolling welded pipe 2 is inserted through the two side uprights 11 and the top crossbeam 12 of the U-shaped frame 1. A gap of 1-2mm is reserved between the rolling welded pipe 2 and the U-shaped frame 1 so that the rolling welded pipe 2 can rotate freely.

[0026] The fixed base 3 is welded to the bottom of the U-shaped frame 1 and is used to fix the device on the trolley cover 4 of the cable 5 lifting path to maintain the stability of the device in a horizontal position.

[0027] Furthermore, the outer diameter of the round steel bar is 2 mm smaller than the inner diameter of the rolling welded pipe 2, in order to avoid the welded pipe getting stuck and to limit its radial sway.

[0028] Furthermore, the surface of the rolling welded pipe 2 is covered with a PVC flexible tube to absorb the impact force of the swinging cable 5.

[0029] Furthermore, the U-shaped frame 1 is fixed to the trolley cover plate 4 by flange bolts, and its center line is aligned with the cable 5 reel and the movement trajectory of the cable 5.

[0030] Furthermore, the cable 5 passes through the middle of the U-shaped frame 1, with a natural drooping arc reserved.

[0031] Rolling anti-jamming design: When the cable 5 contacts the rolling welded pipe 2, the rolling welded pipe 2 can rotate freely with the movement of the cable 5, converting sliding friction into rolling friction and reducing wear.

[0032] Gap optimization: The outer diameter of the round steel is 2mm smaller than the inner diameter of the rolling welded pipe 2, which avoids jamming and limits the large radial sway of the welded pipe.

[0033] Lubricating grease is applied regularly between the rolling welded pipe 2 and the round steel to further reduce the coefficient of friction.

[0034] Installation steps:

[0035] The U-shaped frame 1 is fixed to the trolley cover 4 of the cable 5 lifting path with flange bolts, ensuring that the center line of the U-shaped frame 1 is aligned with the cable drum and the movement trajectory of the cable 5.

[0036] Cable 5 passes through the middle of U-shaped frame 1, with a natural drooping arc reserved to avoid excessive tension.

[0037] Regularly check the rotation status of the rolling welded pipe 2, inject grease to maintain its flexibility, and replace the welded pipe when wear exceeds the standard.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
