[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0025] See the appendix Figure 1, A shock-absorbing installation structure for a vehicle-mounted CT device, including a cabin 1, which is fixedly installed on the trailer chassis of a tractor.

[0026] The tractor is 6x4, with a towing mass of not less than 30 tons. The trailer chassis is a 12-meter air suspension skeleton trailer chassis, which is used as the bearing chassis of the cabin. The trailer chassis is equipped with air suspension shock absorption, which can minimize the impact of road bumps during driving on the equipment. The trailer chassis is equipped with corner fittings locks to lock the corner fittings of the cabin and fix the cabin.

[0027] The interior of the cabin 1 adopts a "day" - shaped layout to separate doctors and patients and avoid cross - infection. Specifically, the cabin 1 is a rectangular box, and the interior of the cabin is successively divided into a CT examination room 1 - 1, an operation room 1 - 2, and an equipment room 1 - 3 along the length direction of the cabin.

[0028] On the side wall of the CT examination room 1 - 1, there are a patient access door 1 - 11 and a maintenance door 1 - 12. The patient access door is for patients to enter and exit, and the maintenance door is used for the installation, commissioning, and later maintenance and repair of the CT device. The number of maintenance doors 1 - 12 is two, and the two maintenance doors are respectively arranged on two opposite side walls of the CT examination room. The two maintenance doors are staggeredly arranged, not symmetrically placed, which is convenient for the disassembly, assembly, and movement of the front and rear decorative covers of the CT. On the side wall of the operation room 1 - 2, there is a medical staff door 1 - 21, which is convenient for medical staff to enter and exit, thus effectively separating doctors and patients, achieving spatial isolation, and effectively avoiding cross - infection, especially having practical significance for the diagnosis of infectious diseases.

[0029] Inside the CT examination room of the cabin, there is a CT device 4. See the appendix Figure 2 , The CT device includes two split parts, a CT scanner 4 - 1 and a CT bed 4 - 2. The bottoms of the CT scanner 4 - 1 and the CT bed 4 - 2 are respectively installed on the bottom surface of the cabin through shock - absorbing devices. Further, preferably, two shock - absorbing devices are installed at the bottom of the CT scanner, and the two shock - absorbing devices are located near the left and right sides of the bottom of the CT scanner; preferably, two shock - absorbing devices are installed at the bottom of the CT bed, and the two shock - absorbing devices are located near the front and rear sides of the bottom of the CT bed.

[0030] Specifically, see the appendix Figures 3 - 6, the structure of the shock absorber 5-1 at the bottom of the CT scanner is as follows: It includes a CT mounting plate 5-11, a transverse wire rope shock absorber group 5-12, a vertical adjustment and locking device group 5-13, and a ground fixing bottom plate 5-14. The transverse wire rope shock absorber group 5-12 and the vertical adjustment and locking device group 5-13 are installed between the CT mounting plate 5-11 and the ground fixing bottom plate 5-14. The CT mounting plate 5-11 is fixed to the bottom of the CT scanner 4-1 by bolts, and the ground fixing bottom plate 5-14 is fixed to the ground of the CT examination room by bolts. Among them, the transverse wire rope shock absorber group includes 4 transverse wire rope shock absorbers. The 4 transverse wire rope shock absorbers are arranged in a square. Each transverse wire rope shock absorber includes upper and lower coil bundle fixed mounting keels 5-12a and 5-12b. A rigid wire rope 5-12c is spirally penetrated and installed between the upper and lower coil bundle fixed mounting keels. The upper coil bundle fixed mounting keel 5-12a is fixed to the CT mounting plate 5-11 by screws, and the lower coil bundle fixed mounting keel 5-12b is fixed to the ground fixing bottom plate 5-14 by screws. The vertical adjustment and locking device group includes 4 vertical adjustment and locking devices. The 4 vertical adjustment and locking devices are respectively arranged at the 4 vertex positions of the square formed by the 4 transverse wire rope shock absorbers. Each vertical adjustment and locking device includes a base 5-13b, a spring 5-13c, and a top seat 5-13a. The base 5-13b is a cylindrical shape with a chassis, and the top seat 5-13a is a cylindrical shape with a top plate. The cylinder of the top seat and the cylinder of the base are installed oppositely. The spring 5-13c is installed between the base and the top seat. The diameter of the cylinder of the base is larger than that of the cylinder of the top seat, so that the cylinder of the top seat can be placed into the cylinder of the base, and there is a certain gap between the cylinders of the base and the top seat, so that the top seat can be radially offset, thereby providing shock absorption movement; there are screw holes on the chassis of the base, and the chassis of the base is fixed to the ground fixing bottom plate by screws; there are also screw holes on the top plate of the top seat, and the top plate of the top seat is fixed to the CT mounting plate by screws. Through the shock absorption structure composed of the above transverse wire rope shock absorber group and vertical adjustment and locking device group, it can effectively buffer the impact loads in all directions of up and down, front and back, and left and right during the vehicle driving process, and effectively protect precision components such as CT slip ring bearings.

[0031] Similarly, refer to the appendix Figures 7 - 8, the structure of the shock absorber 5-2 at the bottom of the CT table is as follows: It includes a CT mounting plate 5-21, a horizontal wire rope shock absorber group 5-22, a vertical adjustment locking device group 5-23, and a ground fixing bottom plate 5-24. The horizontal wire rope shock absorber group and the vertical adjustment locking device group are installed between the CT mounting plate and the ground fixing bottom plate. The CT mounting plate is fixed to the bottom of the CT scanner by bolts, and the ground fixing bottom plate is fixed to the ground of the CT examination room by bolts. The difference is that the horizontal wire rope shock absorber group includes 2 horizontal wire rope shock absorbers, and the vertical adjustment locking device group includes 2 vertical adjustment locking devices. The 2 horizontal wire rope shock absorbers are arranged in a straight line, and the 2 vertical adjustment locking devices are respectively located at the side ends of the 2 horizontal wire rope shock absorbers.

[0032] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0033] Moreover, relative terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0034] The above is an exemplary description of the present invention. It should be noted that without departing from the core of the present invention, any simple deformation, modification, or equivalent replacement that can be made by those skilled in the art without creative labor falls within the protection scope of the present invention.
