Description

Technical Field

[0001] This patent application is a divisional application of the patent application with the application number 2023235386238. The utility model relates to a guiding structure, in particular to a sleeve guiding structure which is installed on a converter gas holder and guides the steel wire rope used in its leveling device. Background Art

[0002] At present, a leveling device needs to be adopted on a converter gas holder, such as the "leveling device for a converter gas holder" of Chinese Patent CN201922176433.3 applied by our company. During the adjustment process, in order to prevent the steel wire rope from hitting the surrounding personnel due to shaking during operation, a protective cover needs to be installed. However, it is found in actual use that if the protective cover is set too small, the steel wire rope is likely to frequently rub against the cover wall, resulting in serious wear. If the protective cover is too large, it will undoubtedly increase the floor area of the entire gas holder. Therefore, a limit guiding mechanism needs to be installed to restrict the steel wire rope, so that it can shake within a limited range, which is beneficial to reducing the volume of the protective cover, not only beneficial to reducing costs, but also beneficial to realizing miniaturization. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above deficiencies and provide a guiding structure for a converter gas holder, which restricts the steel wire rope within the moving swing amplitude through the design of an inner sleeve and an outer sleeve that can slide relative to each other.

[0004] The purpose of the utility model is achieved as follows:

[0005] A guiding structure for a converter gas holder includes an outer sleeve fixedly installed on a mounting plate, an inner sleeve fixedly inserted on an adjusting plate, the adjusting plate is slidably placed on the top of the outer sleeve, and the lower part of the inner sleeve passes through the adjusting plate and is located inside the outer sleeve.

[0006] Preferably, a rubber inner lining cylinder is attached to the inner cylinder wall of the outer sleeve.

[0007] Preferably, the rubber inner lining cylinder is composed of a plurality of vertically arranged rubber strips, and the plurality of rubber strips lined on the inner cylinder wall of the rubber inner lining cylinder are overlapped left and right to form a cylindrical structure.

[0008] Preferably, bell mouths are arranged at both the upper and lower open ends of the inner sleeve.

[0009] Preferably, a wear-resistant sleeve composed of a ceramic wear-resistant layer is arranged on the inner cylinder wall of the inner sleeve.

[0010] Preferably, a wear-resistant layer composed of polytetrafluoroethylene is arranged on the bottom surface of the adjusting plate.

[0011] A guiding structure for a converter gas holder, comprising an adjusting plate slidably placed on the open end of the outer sleeve. The adjusting plate is composed of two butt plates on the left and right, and semi-circular grooves are provided on both butt plates. An arc plate is embedded and fixed in the semi-circular groove, and the two arc plates are joined together to form an inner sleeve. Connecting ear plates are provided on the side walls of both sides of the two arc plates.

[0012] Preferably, semi-trumpet mouths are provided at the upper starting ends of the arc plates, and the semi-trumpet mouths formed by joining the two arc plates together form a complete trumpet mouth.

[0013] Preferably, a wear-resistant layer composed of ceramic wear resistance is provided on the inner wall of the arc plate.

[0014] Preferably, the bottom surface of the butt plate is sprayed with a wear-resistant layer composed of polytetrafluoroethylene.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] After adopting the present utility model, the steel wire rope plays a preliminary limiting and guiding role after passing through the inner sleeve. And because the adjusting plate fixedly connected with the inner sleeve is slidably arranged on the outer sleeve, when the steel wire rope shakes, the steel wire rope can drive the inner sleeve to shake back and forth, left and right in the outer sleeve, and a secondary limiting effect is achieved through the outer sleeve, greatly reducing the shaking amplitude. And through the design of the inner and outer sleeves, contact between the steel wire rope and the outer sleeve is avoided, and for the steel wire rope in the inner sleeve, due to the follow-up design of the inner sleeve, the friction between the steel wire rope and the inner sleeve is also greatly reduced, which is beneficial to reducing the wear amount and prolonging its service life.

[0018] Figure 2 It is a schematic structural diagram of Embodiment 2 of a guiding structure for a converter gas holder of the present utility model.

[0019] Wherein:

[0020] Outer sleeve 1, inner sleeve 2, adjusting plate 3, mounting plate 4;

[0021] Rubber lining tube 1.1;

[0022] Trumpet mouth 2.1, wear-resistant sleeve 2.2 (ceramic wear-resistant coating), arc plate 2.3, connecting ear plate 2.4;

[0023] Wear-resistant layer 3.1 (polytetrafluoroethylene flat coating), butt plate 3.2. DETAILED DESCRIPTION OF THE EMBODIMENTS Embodiment 1:

[0024] See Figure 1 Figure 1 , a guiding structure of a converter gas holder according to the present utility model includes a fixedly installed outer sleeve 1, and a rubber inner lining cylinder 1.1 is attached to the inner cylinder wall of the outer sleeve 1. Specifically, the rubber inner lining cylinder 1.1 is composed of a plurality of vertically arranged rubber strips. The rubber strips lined on the inner cylinder wall of the rubber inner lining cylinder 1.1 are attached by back glue. After the plurality of rubber strips are overlapped left and right, they form a cylindrical structure, and by heating, the adjacent rubbers are sulfur-bonded into an integral structure and attached to the inner wall of the rubber inner lining cylinder 1.1.

[0025] The inner sleeve 2 is fixedly inserted into the adjusting plate 3, that is, the upper end and the lower end of the inner sleeve 2 are respectively located on both sides of the adjusting plate 3. During assembly, since the upper and lower open ends of the inner sleeve 2 are both turned outwards with a flared opening 2.1 of an arc structure (the provided flared opening 2.1 can guide the steel wire rope, making its rising or falling smoother and avoiding the friction between the steel wire rope and the wall of the upper and lower open ends of the inner sleeve 2, which affects the service life of the steel wire rope), the aperture of the through hole on the adjusting plate 3 for the inner sleeve 2 to pass through is larger than the outer diameter of the inner sleeve 2. After the inner sleeve 2 is inserted into the adjusting plate 3, solder is filled between the outer wall of the inner sleeve 2 and the adjusting plate 3 and then welded together to form a fixedly connected integral structure.

[0026] Preferably, a wear-resistant sleeve 2.2 composed of a ceramic wear-resistant layer is provided on the inner cylinder wall of the inner sleeve 2, so that better wear resistance can be provided when the steel wire rope passes through the inner sleeve 2. And since the inner sleeve 2 can move back and forth, left and right along with the adjusting plate 3, when the steel wire rope shakes, the follow-up mode of the inner sleeve 2 can relieve most of the lateral pressure, thus greatly reducing the friction force between the steel wire rope and the inner wall of the inner sleeve 2, thereby reducing its wear amount (and the smaller friction force makes the steel wire rope not drive the inner sleeve 2 to move upwards when moving upwards), greatly prolonging its service life.

[0027] At the same time, a wear-resistant layer 3.1 composed of a polytetrafluoroethylene layer is sprayed on the bottom surface of the adjusting plate 3. Through the polytetrafluoroethylene layer, not only the sliding of the adjusting plate 3 on the outer sleeve 1 is smoother, but also the polytetrafluoroethylene layer has strong wear resistance, which helps to prolong its service life.

[0028] During the assembly of the present utility model, different installations can be carried out according to the actual model of the converter gas holder. When the leveling device does not need to pass through the horizontal plate of the cabinet body, the outer sleeve 1 is fixed on the mounting plate 4, and the mounting plate 4 is fixedly installed on the side wall of the gas holder cabinet body; when the leveling device needs to pass through the horizontal plate of the cabinet body, the outer sleeve 1 is directly fixedly connected through the horizontal plate of the gas holder cabinet body.

[0029] During the use of the leveling device, the inner sleeve 2 limits the steel wire rope, and the inner sleeve 2 plays a follow-up role with the steel wire rope, reducing the sway amplitude of the steel wire rope. Embodiment 2:

[0030] When the outer sleeve 1 is directly inserted and fixed on the horizontal plate of the gas holder cabinet body, since the outer sleeve 1 can be modified by borrowing the inherent structure preset on the cabinet body, but since the steel wire rope has been inserted into the cabinet body, if the cylindrical structure of the inner sleeve 2 is adopted, the entire leveling device needs to be disassembled, and then the steel wire rope is passed through the inner sleeve 2 and reconnected and assembled, which is time-consuming and laborious and has low efficiency. Therefore, it needs to be adjusted as follows:

[0031] See Figure 2 , at this time, the inner sleeve 2 is divided into two arc-shaped plates 2.3 that are joined together to form a cylindrical structure, and the adjusting plate 3 is divided into two left and right butt plates 3.2. The butting side of the butt plate 3.2 is recessed to form a semi-circular groove for the arc-shaped plate 2.3 to be embedded. After the arc-shaped plate 2.3 is embedded in the semi-circular groove, it is welded to the butt plate 3.2. Connecting ear plates 2.4 are arranged on both side walls of the arc-shaped plate 2.3, so that the arc-shaped plate 2.3 and the connecting ear plate 2.4 form a hoop structure. When modifying a conventional leveling device, only two arc-shaped plates 2.3 need to be joined together on both sides of the steel wire rope to form an inner sleeve 2 for the steel wire rope to pass through, and the assembly is completed by screwing bolts between the connecting ear plates 2.4 of the two arc-shaped plates 2.3. Subsequently, the assembled inner sleeve 2 is inserted downward into the outer sleeve 1, and at the same time, the butt plate 3.2 fixing the arc-shaped plate 2.3 is placed on the top opening end of the outer sleeve 1, so as to quickly realize the modification.

[0032] In addition, it should be noted that the above specific implementation manner is only an optimized solution of this patent, and any changes or improvements made by those skilled in the art according to the above concept are within the protection scope of this patent.
