[0055] In an embodiment of the present application, as shown in Figure 13 During the CT maintenance, assembly and debugging process, the CT rotor needs to be locked to prevent rotation. Therefore, a locking device needs to be arranged on the CT, and the rotor needs to be locked conveniently and quickly. In the embodiment of the present application, the CT rotor bolt assembly 11 is used to achieve the above-mentioned functions, and two schemes are provided.

[0056] The first scheme is shown in Figure 14 and Figure 15As shown, the CT rotor bolt assembly 11 is composed of a first handle 1101, a connecting rod 1102, a first insertion rod 1103, a first compression spring 1104, a first spring hook plate 1105 and a second spring hook plate 1106. The first insertion rod 1103 is easy to slide due to the absence of clamping objects. Therefore, the first spring hook plate 1105 is installed on the stator support 1, the second spring hook plate 1106 is installed on the connecting rod 1102, and the first spring hook plate 1105 and the second spring hook plate 1106 are provided with round holes. The open hook heads at both ends of the first compression spring 1104 are buckled into the round holes. When the first insertion rod 1103 is inserted into the rotor and the first insertion rod 1103 is farthest away from the rotor, the first compression spring 1104 is in the shortest state, so that the first insertion rod 1103 is not easy to slide and can quickly lock the rotor, and the cost is relatively low.

[0057] The second, as shown in Figure 16 and Figure 17 The CT rotor bolt assembly 11 is composed of a bolt fixing block 1107, a second handle 1108, a second insertion rod 1109 and a second compression spring 1110. The bolt fixing block 1107 has a through stepped hole, the second insertion rod 1109 and the second compression spring 1110 are inserted into the through stepped hole, the second compression spring 1110 is sleeved into the small diameter part of the second insertion rod 1109, the end of the second insertion rod 1109 is connected with the second handle 1108, and one end of the bolt fixing block 1107 is provided with two mutually perpendicular slot grooves. When the second handle 1108 is in the locked and released states, the bolt fixing block 1107 has corresponding clamping grooves to ensure locking.

[0058] It can be understood that the setting direction of the first insertion rod 1103 and the second insertion rod 1109 is the circumferential radial direction, and the CT rotor bolt assembly 11 is installed on the stator support 1 without following the rotor movement, which can effectively reduce the structural composition of the rotor assembly 3, thereby reducing the weight of the rotating part, reducing the load of the motor 12, and prolonging the service life.

[0059] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
