[0031] In one embodiment of the present invention, Figure 2 As shown, the stator bracket 1 adopts an integrated design and consists of an intermediate plate 101, a bottom plate 102, an upper plate 103 and a side plate 104, which significantly reduces the dependence on other auxiliary components, thereby simplifying the overall structure. The intermediate plate 101 is not only used to install rotating components such as the bearing 14, the large pulley 4 and the small pulley 5, but also used to support and connect the slip ring cover assembly 8, the tensioning wheel assembly 9 and the motor 12.

A 2mm deep groove is cut out at the lower right corner of the intermediate plate 101 for installing the tensioning wheel assembly 9 and the motor adapter plate 13.

[0032] In one embodiment of the present invention, Figures 3 to 8As shown, the slip ring cover assembly 8 is composed of a slip ring cover module and a drawer module 802, wherein the slip ring cover module is composed of a slip ring cover disc 8011, a large arc 8012 on the side of the slip ring cover, a slip ring cover fixing piece 8013, a slip ring cover rib 8014, a fixing block 8015, a baffle 8016 and a baffle bracket 8017. It is fixedly mounted on the five protrusions of the stator bracket 1 through the slip ring cover fixing piece 8013. The slip ring cover disc 8011 can be made of a lightweight acrylic material, which not only provides good protection performance, but also has the advantages of high transparency and light weight, making it easy to directly observe the operating status of the internal part of the slip ring, which is conducive to timely detection of wear and fault problems and reducing maintenance and inspection time. The number of disassembly times improves maintenance efficiency. The baffle 8016 is installed on the baffle bracket 8017. The inner side is arc-shaped, and the arc radius is smaller than the large arc 8012 on the side of the slip ring cover. The arc-shaped sides of the baffle 8016 extend into the large arc 8012 on the side of the slip ring cover to prevent carbon brush dust from being thrown out from the side. The ribs of the baffle 8016 are C-shaped and are used to be fixed on the baffle bracket 8017. There is a 20mm wide rib on one side to receive the splashed carbon powder and make the carbon powder slide down the inner wall of the arc to the bottom of the box module 802. The end faces of the slip ring cover disc 8011 and the slip ring cover rib 8014 are milled with grooves with a width of 4.5mm and a depth of 2mm. The large arc 8012 on the side of the slip ring cover is precisely positioned and fixed by bonding. The slip ring cover disc 8011 and the slip ring cover rib 8014 are fixed on both sides with rectangular blocks and fixed with M4 screws. This not only effectively prevents the risk of components falling off due to aging or failure of glue during long-term use of the equipment, but also further enhances the overall stability of the module and ensures the reliable fixation of the slip ring cover fixing part 8013; the drawer module 802 is composed of an acrylic base plate 8021, a push-pull lock buckle 8022, a push-pull lock tongue 8023 and a drawer 8024.

It is bent into a hook shape to facilitate grabbing the drawer box 8024. Two holes are punched on the left side of the hook of the drawer box 8024 to fix the push-pull lock tongue 8023. The push-pull lock buckle 8022 is integrated into the drawer box module 802, and the push-pull lock buckle 8022 is fixedly installed on the slip ring cover disc 8011 to ensure that the drawer box 8024 can be easily pushed and pulled. There are mounting holes on the acrylic base plate 8021 for guiding and positioning the drawer box 8024, which facilitates the positioning function of the drawer box 8024 during blind insertion and prevents the problem of up and down shaking during transportation. It is not only convenient for cleaning carbon powder, but also makes the installation and disassembly of the drawer box 8024 more convenient, thereby improving the efficiency of maintenance and repair and reducing maintenance costs.

[0033] In one embodiment of the present invention, Figures 9 to 11As shown, the tensioning wheel assembly 9 consists of a tensioning wheel 901, a tensioning rod 902, a tensioning seat 903, an adjusting tensioning rod 904, a tensioning bracket 905, a tensioning bearing 906 and a bearing shaft fixing part 907. The adjusting tensioning rod 904 is designed to accurately adjust the position of the tensioning rod 902, thereby adjusting the position of the tensioning wheel 901 and achieving precise control of the tension of the synchronous belt 6. After the adjustment is completed, it can be fixed by two M10 combination screws, which simplifies the part structure and reduces the part management and manufacturing costs. The tensioning seat 903 and the tensioning bracket 905 are both centrally installed on the stator bracket 1. The tensioning seat 903 adopts a mountain-shaped design structure to facilitate the tensioning rod 902 to be positioned in the tensioning seat 903. 9024 is connected to one end of the tensioning rod 904.

[0034] In one embodiment of the present invention, Figure 12 As shown, the sound insulation cover assembly 10 consists of a sound insulation cover 1001 and sound insulation cotton 1002. The left side of the sound insulation cover 1001 adopts a mountain-shaped structure design to make an avoidance hole for the synchronous belt 6 to pass through. The sound insulation cotton 1002 is set to a wave shape with a height of 20mm. Three sides of the sound insulation cover 1001 are inserted into the motor adapter plate 13, and the other side is fixed by screws. The sound insulation cover assembly 10 not only reduces the spread of noise and protects the hearing health of the operator, but also improves work efficiency and the stability of equipment operation.

[0035] In one embodiment of the present invention, Figure 13 As shown, during the maintenance, assembly, and debugging of a CT, it is necessary to lock the CT rotor to prevent it from rotating. Therefore, a locking device is required on the CT, and the rotor needs to be locked conveniently and quickly. In an embodiment of the present invention, this is achieved through a CT rotor latch assembly 11, and there are two solutions: The first one, such as Figure 14 and Figure 15As shown, the CT rotor latch 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. Since there is no clamping object, the first insertion rod 1103 is easy to slide. Therefore, by providing the first compression spring 1104, the first spring hook plate 1105 and the second spring hook plate 1106, the first spring hook plate 1105 is installed on the stator bracket 1, and the second spring hook plate 1106 is installed on the connecting rod 1102. The first spring hook plate 1105 and the second spring hook plate 1106 are both provided with round holes, and the open hooks 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 when the first insertion rod 1103 is farthest 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 the rotor can be quickly locked with low cost. The second type, such as Figure 16 and Figure 17 As shown, the CT rotor latch assembly 11 consists of a latch fixing block 1107, a second handle 1108, a second insertion rod 1109 and a second compression spring 1110. The latch fixing block 1107 has a through-step hole, through which the second insertion rod 1109 and the second compression spring 1110 are inserted. The second compression spring 1110 is inserted into the small-diameter portion of the second insertion rod 1109. The end of the second insertion rod 1109 is connected to the second handle 1108. One end of the latch fixing block 1107 is provided with two mutually perpendicular slots. When the second handle 1108 is in the locked and released states, the latch fixing block 1107 has corresponding slots to ensure locking.

[0036] It can be understood that the setting directions of the first plug rod 1103 and the second plug rod 1109 are both circumferential and radial, and the CT rotor pin assembly 11 is installed on the stator bracket 1, and does not need to follow the movement of the rotor, 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 extending the service life.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
