Description
TECHNICAL FIELD
[0001] The utility model belongs to hot strip production technical field, especially relate to a device special for replacing laminar cooling roller way motor. BACKGROUND
[0002] It is known that laminar cooling roller way is an important component part in the production process of hot strip, and the roller way motor plays a vital role in this process, which not only has a decisive influence on the quality of the steel, but also has a large number of motors, up to hundreds of motors in the laminar cooling area and the entry roller way of the coiler. With the passage of time, the service life of these motors gradually increases, and the frequency of damage and the number of replacements also increase significantly. However, due to the limited space inside the roller way motor cover plate, the layout is compact, and the motor adopts a tail terminal box design, so the distance between the box cover and the cover plate is very close. In addition, the screws on the box cover are mostly outside hexagonal M4*20 bolts, which further increases the difficulty of disassembly. Due to the narrow space, traditional open-end wrenches, ratchet wrenches and other tools are difficult to operate, resulting in a time of about 15 minutes for disassembling and assembling a motor. During the disassembly process, two of the four fixed screws need to be blind disassembled, which undoubtedly increases the complexity and risk of operation. When the motor is disassembled and connected during the time of roll changing in the finishing mill, the equipment maintenance personnel need to remove the motor cover plate, which often leads to exceeding the scheduled roll changing time. If you choose to buy suitable special tools, the cost is high, and it cannot be guaranteed that every worker can be equipped. Therefore, how to quickly and safely replace and disassemble the motor has become a problem to be solved. The development of a more convenient and practical replacement tool will directly affect the length and safety of the replacement process. SUMMARY
[0003] In view of the problems existing in the prior art, the utility model provides a device special for replacing laminar cooling roller way motor, which can quickly and safely replace and disassemble the motor in a narrow space.
[0004] The utility model adopts the technical scheme of:
[0005] A device special for replacing laminar cooling roller way motor, comprising:

[0017] The design of the utility model adopts the overall T-shaped structure, which is not only compact in structure, but also practical. In the design, the size range of the two arms is particularly limited to ensure the stability and applicability of the structure. By adopting the technical scheme, the time for replacing the layer cold roller way motor disconnection is greatly shortened. This improvement significantly improves the convenience of disassembly work, and completely changes the inconvenience of having to use a long handle tool for operation in the past.

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.
[0023] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0024] Through multiple observations and actual operations in the production site, the engineers found that the main factors affecting the replacement speed at the present stage are two: first, the applicability of the replacement tool is insufficient; second, the lack of cooperation of equipment personnel to remove the cover plate directly leads to the extension of the time to disassemble the motor. Therefore, how to meet the demand of quickly disassembling the motor while solving the problem of lack of cooperation of equipment personnel has become the core problem that needs to be solved by the present application. This not only relates to the improvement of production efficiency, but also relates to the safety and reliability of the entire production process.
[0025] Referring to Figure 1 and Figure 2 A device dedicated to the motor of a cold roller of a changeover layer, comprising:
[0026] The first working rod 1 is designed to have a special structure at one end, that is, a first working head 1-1 is arranged at the end. The end face of the first working head 1-1 is designed to have a concave regular hexagonal structure that can perfectly match the external hexagonal M4*20 bolt. This design enables the first working rod 1 to conveniently match the parts with the corresponding external hexagonal thread. In addition, the total length of the first working rod 1 and the first working head 1-1 is strictly controlled to be not more than 85 mm, and such size limitation ensures that the first working rod 1 meets the use demand of narrow space in actual application.
[0027] The second working rod 2 has similar design features as the first working rod 1. A second working head 2-1 is also arranged at one end of the second working rod 2, and the end face thereof is also designed to have a concave regular hexagonal structure that matches the external hexagonal M4*20 bolt. The total length of the second working rod 2 and the second working head 2-1 is also not more than 85 mm, and such design ensures that the second working rod 2 meets the use demand of narrow space when in use, while having convenience and high efficiency in use.
[0028] It is particularly worth noting that the first working rod 1 and the second working rod 2 are designed to be perpendicular to each other. Such perpendicular structure design enables the two to form a stable T-shaped structure. In addition, the other end of the first working rod 1 and the side wall of the second working rod 2 are fixedly connected in a certain way, and the connection way can be welding, threaded connection or other mechanical fixing way, which ensures the stability and reliability of the T-shaped structure.
[0029] In order to better understand the technical content of the utility model, the following is non-limiting:
[0030] In the present application, the sizes of the first working rod 1 and the second working rod 2 are exactly the same.
[0031] Specifically, the lengths of the first working rod 1 and the second working rod 2 are designed to be consistent, and the numerical values are both 70 mm.
[0032] In addition, the first working head 1-1 and the second working head 2-1 both adopt a cylindrical design.
[0033] In terms of size, the heights of the first working head 1-1 and the second working head 2-1 are set to the same numerical value.
[0034] Further, the heights of the first working head 1-1 and the second working head 2-1 are both 12 mm.
[0035] For the concave regular hexagon structure, the length of each side is precisely set to 17.7 mm.
[0036] The forming process of the device special for replacing the motor of the cold roller of the layer is that through observation of the present used tool and multiple practices for the modified sleeve, the first working rod 1 and the first working head 1-1 can be integrally formed, the second working rod 2 and the second working head 2-1 can be integrally formed, for example, M12*70 internal hexagonal bolts can be selected, two bolts are welded into T shape with one horizontally and one vertically, and the self-made sleeve tool is made. The length of the self-made sleeve tool is very convenient to insert into the gap between the motor cover plate and the motor junction box, and there is enough space for the user to disassemble. The head of the bolt is a concave regular hexagon, which is exactly the size of the external hexagonal M4*20 bolt of the motor junction box cover, which can achieve the purpose of rotating the screw. And it is found in the test process that the self-made M12*70 internal hexagonal bolt sleeve can also disassemble the terminal nut inside the junction box, so that the motor can be disassembled and connected in the process of not affecting the equipment maintenance personnel to disassemble the cover plate, which greatly shortens the time of replacing the roller motor and disassembling the connection.
[0037] The above only describes the preferred embodiments of the present application, and is not intended to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application is included in the protection scope of the present application.
