Description

Technical Field

[0001] This utility model relates to the technical field of coupling disassembly equipment, and in particular to a coupling disassembly device. Background Technology

[0002] Couplings are mainly used for connecting shafts to transmit motion and torque, and therefore play a very significant role in the metallurgical industry. In continuous annealing production lines, tension rollers work together to establish and maintain the tension of the annealing unit. To meet the load transmission requirements, the universal coupling flange of the tension roller is designed as a keyless cylindrical connection with a large interference fit, with a maximum interference fit of 0.268 mm.

[0003] In existing technology, the coupling on the roller side must be disassembled each time the tension roller is replaced. Current disassembly methods mainly rely on large machine tools, but the cost of purchasing such tools is too high. Furthermore, existing disassembly methods typically involve directly and destructively cutting off the coupling, which not only wastes a significant amount of spare parts but also increases operating costs. For the numerous tension rollers (48 in total) in the unit, this traditional disassembly method is clearly insufficient in both cost and efficiency. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0031] This utility model provides a technical solution: a coupling disassembly device, such as... Figure 1-5 As shown, it includes: a dismantling frame main body assembly and a high-pressure oil pump 6; a coupling 8 is placed in the concave opening inside the force plate frame 1 of the dismantling frame main body assembly; the high-pressure oil pump 6 is connected to the coupling 8 through a pipeline;

[0032] The main dismantling frame consists of a load-bearing plate frame 1, a reinforcing plate 2, a hydraulic jack 3, a support plate 301, an adjusting bolt 302, a support frame 4, and pulleys 5. The load-bearing plate frame 1 has reinforcing plates 2 on both the left and right sides and on the top and bottom. The load-bearing plate frame 1 has a support plate 301 located inside the frame away from the opening. The hydraulic jack 3 is positioned above the support plate 301. An adjusting bolt 302 passes through the center of the support plate 301. Support frames 4 are located at the four corners of the bottom of the load-bearing plate frame 1. Pulleys 5 are located at the bottom of each support frame 4.

[0033] A push rod 7 is provided between the hydraulic jack 3 and the shaft head 801 on the coupling 8 to transmit the thrust of the hydraulic jack 3 to the shaft head 801.

[0034] A pad 10 is inserted between the hydraulic jack 3 and the load-bearing plate frame 1; the pad 10 is T-shaped; the rear support of the hydraulic jack 3 is provided with a T-shaped pad 10 with a thickness of 100mm that can be added or removed during the pulling process.

[0035] The load-bearing plate frame 1 is made of a material with high strength and high rigidity.

[0036] The load-bearing plate frame 1 is made of X80 high-strength steel with a thickness of 130mm. Its internal hollow dimensions are 495mm wide and 1375mm long. The upper and lower parts of the L-shaped load-bearing surface of the load-bearing plate frame 1 are welded with reinforcing plates 2 with a thickness of 100mm.

[0037] The support plate 301 consists of multiple U-shaped support components used to support and fix the hydraulic jack 3.

[0038] The bolt 302 is M12. The M12 adjusting bolt 302 is used to adjust the horizontal height of the hydraulic jack 3 on the support plate 301, so that the horizontal center position of the hydraulic jack 3 is kept at the center of the force plate 3.

[0039] The high-pressure oil pump 6 includes multiple high-pressure oil pumps, which are manually operated; a high-pressure manual pressurizing pump nozzle (G1 / 4) and oil pipe are installed, and the manual pressurizing pump pressurizes (to check for leaks) at a pressure of 200MPa.

[0040] The usage process of this utility model is as follows:

[0041] First, use a crane to place the roller 9 and the coupling 8 at the concave opening of the load-bearing plate frame 1, with the concave opening aligned with the end face of the coupling 8.

[0042] The hydraulic jack 3 is then horizontally positioned above the support plate 301. The height of the hydraulic jack 3 is controlled by adjusting the height of the adjusting bolt 302 on the support plate 301. The hydraulic jack 3, the push rod 7, the load-bearing plate frame 1, and the coupling 8 are then adjusted to the same horizontal position.

[0043] Start the hydraulic jack 3 to apply pressure, so that the push rod 7, hydraulic jack 3, coupling 8 and load-bearing plate frame 1 abut against each other and maintain the pressure state;

[0044] Since the coupling 8 is a keyless cylindrical interference fit connection, in order to prevent damage to the mating surface between the coupling 8 and the shaft head 801, pressurized oil is injected into the mating surface between the coupling 8 and the shaft head 801 by the high-pressure oil pump 6, so that the interference fit parts undergo elastic deformation.

[0045] After manually operating the high-pressure oil pump 6 until the pressure is sufficient, the hydraulic jack 3 begins to pressurize until the coupling 8 is pulled out. The high-pressure oil pump 6 is manually operated to continue pressurizing, maintaining the pressure at around 200MPa. When the stroke of the hydraulic jack 3 is about to end, the hydraulic jack 3 retracts, and the rear is inserted into the T-shaped pad. Pressurize again until the coupling is pulled out (the coupling and the jack rod are supported by a crane to prevent them from falling).

[0046] The mating parts are disassembled by using the axial pulling force of the hydraulic jack 3.

[0047] This utility model, by setting up a disassembly frame main device, a high-pressure oil pump 6 and a push rod 7, avoids structural damage and large cost consumption caused by destructive cutting of the coupling, as well as the problem of low disassembly efficiency, thereby saving equipment costs and providing strong support for normal production. It significantly reduces labor costs and maintenance time, greatly improves production efficiency, and has a simple structure, is easy to use, has high disassembly efficiency and strong applicability.

[0048] 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.
