Description

Technical Field

[0001] The utility model relates to a stator outlet structure of a rolling mill with a protective cover structure. Background Art

[0002] At present, the motors of rolling mills with protective cover structures are all wired from the bottom of the copper bar, and the copper plate of the wire is exposed outside the motor. There is no wire box protection at the connection with the user's power supply line. Figure 1 As shown, in the base 4 under the protective cover 1, the copper busbar is fixed by the bakelite wire clamp 2 to the lower conductive busbar 3. When the user requires side outlet with outlet box, because the outlets on both sides of the base are open, the outlet gear is located between the base and the outer cover. During transportation and maintenance, the base and the outer cover are two parts that need to be separated, and it is impossible to install a fixed wire clamp between the two to fix the outlet copper busbar or cable. Therefore, when designing, it is necessary to consider the reliability of the outlet method and the impact on the later lifting in and out of the protective cover. Summary of the invention

[0003] The utility model aims to provide a lead-out structure of the side lead-out wires of a rolling mill motor with a protective cover structure, so as to effectively meet different wiring modes of users on site.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a protective cover structure rolling mill stator outlet structure, including an outlet box, a protective cover, a machine base, an outlet bracket, a bakelite board, an insulating sleeve and a connecting cable, two outlet brackets arranged up and down are cantilevered on one side of the machine base, a bakelite board is fixed between the two outlet brackets, holes are opened on the bakelite board and an insulating sleeve is put on it for fixing the cable.

[0005] Furthermore, a protective cover is installed on the outside of the base.

[0006] Furthermore, the protective cover is provided with an outlet box to ensure the protection level of the connection between the user power supply and the motor lead wire.

[0007] Furthermore, the outlet bracket is made of bent flat steel, with a support added in the middle to ensure rigidity.

[0008] Furthermore, the outlet bracket is fixedly connected to the machine base by bolts through screw holes instead of welding, which is simple and easy to disassemble.

[0009] Furthermore, the cable lead-out line of the rolling mill stator of the protective cover structure is connected to the conductive bar in the outlet box installed on the protective cover through bolts, which can ensure the reliability and safety of the electrical connection.

[0010] Furthermore, the installation position of the outlet bracket is adapted to the extension length of the cable, so as to ensure that after the stator lead-out cable is disconnected from the conductive bar in the outlet box, the protective cover can be smoothly lifted out and lifted in without removing the outlet box.

[0011] The beneficial effects of the utility model are:

[0012] The stator outlet structure of the protective cover structure rolling mill of the utility model is compared with the original outlet mode of the existing rolling mill protective cover series, which is the copper bar outlet. This technical solution breaks through the existing structure. The stator outlet is located above the motor side. Compared with the existing rolling mill protective cover series in which the stator outlet is located below the machine base, the side outlet makes wiring more convenient and can meet the different wiring arrangements of users on site. At the same time, the installation of the outlet box makes the electrical connection part safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 2 As shown in FIG3 , the stator outlet structure of the rolling mill with the protective cover structure of the utility model comprises a machine base 11, a protective cover 12, an outlet bracket 13, a bakelite board 14, an insulating sleeve 15, a stator lead-out cable 16 and an outlet box 17 mounted on the protective cover.

[0018] A cantilever is connected to two outlet brackets 13 arranged up and down on one side of the base 11, and a bakelite board 14 is fixedly connected between the two outlet brackets 13. The bakelite board 14 has holes and is equipped with an insulating sleeve 15 for fixing the cable. A protective cover 12 is installed outside the base 11.

[0019] In order to overcome the problems existing in the lower wire outlet structure of the rolling mill stator with the existing protective cover structure, the utility model adopts a cantilever support method of the wire outlet bracket 13 (two on one side, upper and lower), and screw holes are pre-drilled on the machine base 11 for fixing the wire outlet bracket 13, and the other side is suspended. The wire outlet bracket 13 is made of flat steel and a support is added in the middle to ensure rigidity. The bakelite board 14 is fixed on the wire outlet bracket 13. The bakelite board 14 is opened with a hole and equipped with an insulating sleeve 15 for fixing the cable. The outer side of the protective cover 12 is equipped with a wire outlet box 17, and the cable 16 and the conductive bar in the wire outlet box 17 are bolted together. At the same time, pay attention to the installation position of the wire outlet bracket 13 and the extension length of the cable 16 to ensure that after the bolts of the cable 16 and the wire outlet box 17 are removed, the cable can be pulled back into the machine base 11 without affecting the lifting out and lifting in of the protective cover 12.
