DETAILED DESCRIPTION

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Referring to Figures 1 to 4As shown in the embodiment, the driving mechanism for the mobile CT machine comprises a connecting plate 1, a shaft seat assembly 2 mounted on the connecting plate 1, a rotating shaft assembly 3 rotatably connected with the shaft seat assembly 2, a support 6 fastened with the shaft seat assembly 2, and a power assembly 7 arranged on the support 6 for driving the rotating shaft assembly 3 to rotate; the rotating shaft assembly 3 comprises a hollow rotating shaft 31 and a sliding wire assembly 4 arranged in the cavity of the hollow rotating shaft 31; the power assembly 7 is provided with a wire protection tube assembly 5 which is coaxially and throughly arranged with the hollow rotating shaft 31.

[0031] The driving mechanism arranged by the above scheme makes the wire protection tube assembly 5 coaxially and throughly arranged with the hollow rotating shaft 31, and then the sliding wire assembly 4 is hidden in the cavity of the hollow rotating shaft 31, and the wire protection tube assembly 5 is arranged in the power assembly 7, so that the cable is connected with the sliding wire assembly 4 through the wire protection tube assembly 5, thereby avoiding the abrasion of the cable caused by the operation of the driving mechanism and finally leading to the breakage of the cable, and effectively improving the reliability and service life of the equipment.

[0032] Further, in combination with Figure 3 and Figure 4 As shown in the above embodiment, the shaft seat assembly 2 comprises a bearing seat 21 and a bearing 22 fastened with the bearing seat 21, the bearing 22 is matched with the hollow rotating shaft 31, and the driving end of the rotating shaft assembly 3 is exposed on one side of the shaft seat assembly 2 and is provided with a C ring. That is, the C ring is mounted on the exposed end of the hollow rotating shaft 31 from the bearing seat 21, compared with the scheme that the C ring is arranged in the middle part of the rotating shaft assembly 3 in the related art, the embodiment can disperse the weight of the C ring through the bearing seat 21; since the C ring is arranged on the end of the hollow rotating shaft 31 close to the bearing seat 21, the exposed end of the hollow rotating shaft 31 has a short arm length, and in comparison, the bearing capacity of the exposed end is relatively large, thus, the installation of the C ring with various weights within the bearing range can be effectively met, and the deformation of the hollow rotating shaft 31 caused by improper installation of the C ring can be avoided.

[0033] Further, in order to facilitate the installation of the power assembly 7 and maintain the coaxiality between the power output end and the hollow rotating shaft 31, the support 6 for supporting the power assembly 7 comprises a first support plate 61 and a second support plate 62 fastened to opposite sides of the bearing seat 21, and a third support plate 63 fastened to the first support plate 61 and the second support plate 62 respectively, wherein the third support plate 63 is arranged opposite to the bearing seat 21. Since the frame formed by the first support plate 61, the second support plate 62 and the third support plate 63 is integrated with the bearing seat 21 after fastening, the power assembly 7 can be installed on the third support plate 63 and connected to the hollow rotating shaft 31. Since the power assembly 7 is installed on the inner side of the third support plate 63, i.e. in the space surrounded by the first support plate 61, the second support plate 62 and the third support plate 63, the power assembly 7, the rotating shaft assembly 3 and the bearing seat assembly 2 are integrated, so that the components are compactly connected, the structure is more compact, the space occupation is smaller, and the stability of the entire driving mechanism is improved.

[0034] In order to facilitate the stable and reliable connection between the hollow rotating shaft 31 and the power output end of the power assembly 7, preferably, a first flange 8 is fastened to the driving end of the power assembly 7, and a second flange 9 is arranged at one end of the hollow rotating shaft 31 and fastened to the first flange 8. The fastening of the first flange 8 and the second flange 9 can stably transmit the power output by the power assembly 7 to the hollow rotating shaft 31, and facilitate the disassembly and maintenance between the power assembly 7 and the hollow rotating shaft 31.

[0035] Preferably, the power assembly 7 can be a hollow motor, and the connecting plate 1 is fastened to the body of the mobile CT machine. In this way, the wire protection tube assembly 5 can be coaxially installed in the cavity of the hollow motor and arranged coaxially with the assembled hollow rotating shaft 31. In addition, in order to facilitate the introduction of the wire from the port of the wire protection tube assembly 5 and facilitate the disassembly of the wire protection tube assembly 5, one end of the wire protection tube assembly 5 is exposed outside the third support plate 63.

[0036] The driving mechanism with the above structure can facilitate the installation of the wire protection tube assembly 5 when the power assembly 7 is a hollow motor, effectively reduce the space occupation caused by the external placement of the wire protection tube assembly 5 outside the power assembly 7, and facilitate the coaxial arrangement of the wire protection tube assembly 5 and the hollow rotating shaft 31.

[0037] Further, in combination with the above Figure 4As shown, the hollow rotating shaft 31 comprises a shaft body, a cavity provided at one end of the shaft body, and a through hole provided at the other end of the shaft body and penetrating the cavity. The hollow rotating shaft 31 with the above structure can be assembled with the slide wire assembly 4 installed in the cavity of the shaft body, thereby effectively reducing the space occupation caused by the external slide wire assembly 4. In addition, since the cavity penetrates the through hole, the wiring is also facilitated.

[0038] The embodiment principle of the driving mechanism for the mobile CT machine provided in the present application is that the hollow motor drives the hollow rotating shaft 31 to rotate without affecting the cable. Specifically, when the hollow motor mounted on the support 6 drives the hollow rotating shaft 31 to rotate, since the wire protection tube assembly 5 provided in the hollow motor is coaxially arranged with the slide wire assembly 4 provided in the hollow rotating shaft 31, the driving mechanism can effectively avoid causing abrasion to the cable and finally leading to the breakage of the cable during operation. In addition, since the slide wire assembly 4 is arranged in the cavity of the hollow rotating shaft 31, and the cable is electrically connected with the slide wire assembly 4 through the wire protection tube assembly 5 provided in the hollow motor, the space occupation caused by the external slide wire assembly 4 is greatly reduced, and the wiring is also facilitated.
