In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Figure 1 The external structure of the turning machine provided in this embodiment is shown, and the turning machine mainly includes a base frame 1 and a bracket 2. The base frame 1 has a bottom frame 11 and two columns 12, and the two columns 12 are arranged on the bottom frame 11 opposite to each other. In addition, the bracket 2 includes a bearing platform 21 and two rotating arms 22, and the bearing platform 21 is provided with a plurality of mounting holes 211 for connecting with the target equipment to be maintained; the bottom ends of the two rotating arms 22 are respectively connected to the two sides of the bearing platform 21, and the upper ends of the two rotating arms 22 are rotatably arranged on the two columns 12 through the rotating shaft 23.

[0034] The turning machine provided in this embodiment can be used for maintenance or cleaning of transformers and other equipment. When in use, the target equipment to be maintained can be connected to the supporting platform 21 of the turning machine by bolts through the mounting holes 211 on the supporting platform 21. Then, the target equipment to be maintained can be turned over by rotating the two rotating arms 22 around the rotating shaft 23, so as to facilitate all-round deep cleaning and improve the efficiency of maintenance and cleaning.

[0035] For example, in combination Figure 1 and Figure 2The upper end of the rotating arm 22 is provided with a non-circular groove 2221, one end of the rotating shaft 23 is limitedly matched with the non-circular groove 2221, and the rotating shaft 23 is rotatably arranged on the column 12 through a bearing. In this way, the rotating arm 22 and the rotating shaft 23 can be connected in an interference fit manner, and the matching portion formed by the non-circular groove 2221 can prevent relative displacement between the rotating arm 22 and the rotating shaft 23.

[0036] In a preferred embodiment, the rotating arm 22 may include an arm body 221 and a plate 222, the plate 222 is provided with a non-circular groove 2221, the plate 222 is connected to the rotating shaft 23 through the non-circular groove 2221, and the arm body 221 is connected to the plate 222 through a screw. In this way, the plate 222 and the rotating shaft 23 can be connected first, and then the plate 222 and the arm body 221 can be connected, so that the connection process of the rotating arm 22 is more convenient.

[0037] Continue to refer to Figure 1 The turning machine further comprises a reduction motor 3 and a control cabinet 4. The reduction motor 3 is equipped with a motor, a reducer and a brake 31. For example, the motor can be a gear reduction motor 3, the reducer can be an RV reducer, and the transmission mode of the reducer can be a worm gear transmission.

[0038] The body of the reduction motor 3 is mounted on a column 12, and the output shaft of the reduction motor 3 is connected to a rotating shaft 23. In addition, the control cabinet 4 is connected to the reduction motor 3 via a cable to control the forward rotation, reverse rotation and stop of the motor. In this way, the control cabinet 4 is operated to allow the reduction motor 3 to drive the target device to be maintained to complete the flipping process, which can save more effort. In addition, the flipping process can also be operated by connecting a crank to the rotating shaft 23.

[0039] In a preferred embodiment, in combination Figure 3 and Figure 4 , the control circuit for the reduction motor 3 of the control cabinet 4 can be configured with a forward intermediate relay and a reverse intermediate relay. Among them, the normally open contact 51 of the forward intermediate relay is connected in series in the forward control circuit, and the normally closed contact 52 of the forward intermediate relay is connected in series in the reverse control circuit. The normally open contact 61 of the reverse intermediate relay is connected in series in the reverse control circuit, and the normally closed contact 62 of the reverse intermediate relay is connected in series in the forward control circuit. In this way, the forward and reverse interlocking of the turning machine can be realized, that is, only one of the forward control circuit and the reverse control circuit will be turned on at the same time, and when one circuit is turned on, the other circuit is disconnected.

[0040] In a preferred embodiment, continue to refer to Figure 3In the control circuit for the brake 31 of the control cabinet 4, at least one of the neutral line and the live line is provided with a normally open contact 51 of a forward intermediate relay and a normally open contact 61 of a reverse intermediate relay in parallel. In this way, the brake 31 can be configured so that when the forward control circuit or the reverse control circuit is powered on, the brake 31 is in a separated state; and the brake 31 can be configured so that when both the forward control circuit and the reverse control circuit are powered off, the friction disk of the brake 31 is in a engaged state. It can be understood that the forward intermediate relay and the reverse intermediate relay are both provided with multiple pairs of normally open contacts.

[0041] When the motor is powered on, the coil of the brake device 31 is also powered, the armature is attracted, and the brake shoe of the brake is separated from the brake wheel by overcoming the tension of the spring, and the motor operates normally. When the motor loses power, the coil of the brake device 31 is also powered off, the armature is separated from the iron core under the action of the spring tension, and the brake shoe of the brake tightly holds the brake wheel, and the motor is braked and stops.

[0042] In a preferred embodiment, referring to Figure 4 , the coil 53 of the forward intermediate relay and the forward button switch 71 are connected in series in the first switch circuit, and the coil 63 of the reverse intermediate relay and the reverse button switch 72 are connected in series in the second switch circuit. And, the first switch circuit and the second switch circuit are arranged in parallel and powered by a switch power supply 8. In this way, when the forward button switch 71 is manually operated to turn on, the forward control circuit can be turned on, thereby controlling the forward rotation of the bracket 2 of the flip machine; and when the reverse button switch 72 is manually operated to turn on, the reverse control circuit can be turned on, thereby controlling the reverse rotation of the bracket 2 of the flip machine.

[0043] In a preferred embodiment, continue to refer to Figure 4 The turning machine is also provided with a forward limit switch 91 and a reverse limit switch 92. The normally closed contact of the forward limit switch 91 is connected in series in the first switch circuit. The forward limit switch 91 is provided on the base frame 1, and the forward limit switch 91 is configured to trigger the contact of the forward limit switch 91 to be disconnected when the bracket 2 rotates forward to the first limit position, and the bracket 2 automatically stops at the position for cleaning, thereby reducing manual operation.

[0044] Furthermore, the normally closed contacts of the reversal limit switch 92 are connected in series in the second switch circuit. The reversal limit switch 92 is arranged on the base frame 1, and the reversal limit switch 92 is arranged to trigger the contacts of the reversal limit switch 92 to be disconnected when the bracket 2 rotates in the opposite direction to the first limit position, and the bracket 2 automatically stops there for cleaning work, thereby reducing manual operation.

[0045] For example, the limit switch, also known as the travel switch or position switch, is a commonly used low-current main control electrical appliance. It uses the collision of the moving parts of the production machinery to make its contacts move to connect or disconnect the control circuit to achieve a certain control purpose.

[0046] In a preferred embodiment, continue to refer to Figure 4 The control cabinet 4 is also provided with an emergency stop button switch 73, which is arranged at the power output end of the switching power supply 8 and can control the power on and off of the first switching circuit and the second switching circuit.

[0047] In a preferred embodiment, the control cabinet 4 may also be provided with an operation panel, on which a forward button switch 71, a reverse button switch 72, an emergency stop button switch 73 and a power indicator light are provided.

When in use, the target equipment to be maintained can be connected to the bearing platform 21 of the turning machine by bolts with the aid of the mounting holes 211 on the bearing platform 21 of the bracket 2.
