Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a vehicle-mounted DR capable of automatically switching between a vertical position and a horizontal position. Background Art

[0002] In view of remote areas, areas with inconvenient transportation and shortage of doctors, mobile medical vehicles can use their good mobility to achieve regular cycle diagnosis, cover larger areas and improve the utilization efficiency of medical equipment. DR refers to a new technology of direct digital X-ray photography under computer control, that is, an amorphous silicon flat-panel detector is used to convert X-ray information that penetrates the human body into digital signals, and the computer reconstructs the image and performs a series of image post-processing. As a popular imaging diagnostic device, DR has gradually become one of the standard configurations of mobile medical vehicles. The DR configured on the vehicle can be divided into two types according to the appearance: column type and wall type. However, due to the size of the vehicle and various restrictions, mobile medical vehicles are usually unable to set up a bed for horizontal radiological examinations, which limits their application.

[0003] In the prior art, the patent with application number 201911395146.X discloses a shielding room for vehicle-mounted DR and its arrangement and use method, which utilizes the foldable characteristics of the bed to realize vertical and horizontal dual inspection modes, but it needs to change the use position through the ball tube column track walking device to switch the mode, and when switching the mode, the ball tube needs to be rotated by the ball tube rotation control device before it can be used. The structure is cumbersome, and the position needs to be locked again after adjustment, which is inconvenient to use. In addition, a flat plate is used when in vertical mode, and a folding bed needs to be used when in horizontal mode. Different mechanisms need to be configured, occupying a large area, and reducing space utilization. Therefore, it is necessary to design a vehicle-mounted DR that can automatically switch between vertical and horizontal modes with a simple structure, convenient use, and small space occupation, so as to facilitate flexible use in a limited space.

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments can enable technicians in this field to understand the present invention more comprehensively, but the present invention is not limited to the scope of the embodiments.

[0034] like Figure 1-Figure 11 As shown, this specific embodiment adopts the following technical scheme: it includes a support frame 1, a fixed frame 2, a ball tube 3, a ball tube moving mechanism 4, a bed panel 5, and a bed panel moving mechanism 6; the support frame 1 is a frame-shaped structure to ensure the stability of the overall structure, and fixed frames 2 are longitudinally arranged on both sides of the interior of the support frame 1. The fixed frames 2 include a first fixed frame 21 of different widths for installing the ball tube moving mechanism 4 and a second fixed frame 22 for installing the bed panel moving mechanism 6, and the fixed frame 2 has a limiting and supporting function.

[0035] A first fixed frame 211 is provided inside the first fixed frame 21, and the ball tube moving mechanism 4 is installed in the first fixed frame 21 through the first fixed frame 211. The ball tube moving mechanism 4 can be in the first fixed frame 211, and can also move up along the first fixed frame 211 until it is converted into a horizontal state. The ball tube moving mechanism 4 is a ball tube moving frame, and the ball tube moving frame is driven to move by a ball tube moving frame double driving mechanism 7 provided in the first fixed frame 21. The ball tube moving frame double driving mechanism 7 can drive the ball tube moving mechanism 4 to move up and rotate a certain angle. The ball tube 3 is movably installed on the ball tube moving mechanism 4, and the ball tube 3 is driven to move by a single driving mechanism 8 provided on the ball tube moving mechanism 4. The single driving mechanism 8 drives the ball tube 3 to translate along the ball tube moving mechanism 4.

[0036] One end of the ball tube moving mechanism 4 is fixed with a motor seat through a crossbeam, and a single driving mechanism 8 is installed on the motor seat. The single driving mechanism 8 is a ball tube driving motor 81 and a first rolling screw 82. The output shaft of the ball tube driving motor 81 is connected to the first rolling screw 82 through a coupling. The rotation of the ball tube driving motor 81 drives the first rolling screw 82 to rotate. A corresponding first screw nut 83 is sleeved on the first rolling screw 82. The first screw nut 83 is connected to a first screw nut seat 84. The first screw nut seat 84 is fixed to the ball tube support plate 85. The ball tube 3 is connected to the ball tube support plate 85 through a hoop. When the first rolling screw 82 rotates, the first screw nut 83 can only translate along the first rolling screw 82. The first screw nut 83 is connected to the first rolling screw 82 through the first screw nut 83. The screw nut seat 84 drives the ball tube support plate 85 and the ball tube 3 to move, and the position of the ball tube 3 can be adjusted. At the same time, the two sides of the ball tube support plate 85 are respectively connected to the first sliders 86. The two first sliders 86 move along the two first slide rails 87 respectively. The two first slide rails 87 extend along the length direction of the ball tube moving frame. The two first slide rails 87 are respectively arranged on both sides of the ball tube moving frame. When the ball tube support plate 85 moves, it drives the first sliders 86 to move together. The first slide rails 87 play a guiding role, so that the ball tube support plate 85 can realize linear movement. The outer surface of the ball tube moving frame is provided with a cover plate 41, and the ball tube 3 is arranged on the outer side of the cover plate 41. The cover plate 41 is provided with a moving hole for the clamp to move. The cover plate 41 separates the ball tube 3 from the driving structure inside the ball tube moving frame.

[0037] The bottom end of the ball tube moving mechanism 4 is rotatably connected to the fixed shaft 78, and the fixed shaft 78 is supported by a support block 77 fixed on the mounting plate 76. When one end of the ball tube moving mechanism 4 is driven upward by the mounting plate 76, it can realize a certain angle of rotation, and gradually transform into a horizontal state while moving upward. The mounting plate 76 is connected to two second sliders 74, and the two second sliders 74 move along two second slide rails 75 respectively. The second slide rails 75 play a guiding role, so that the mounting plate 76 can move in a straight line. The two second slide rails 75 extend along the length direction of the first fixed frame 211, and the two second slide rails 75 are arranged on both sides inside the first fixed frame 211.

[0038] The second slider 74 and the ball tube moving mechanism 4 are driven to move by the ball tube moving frame double driving mechanism 7. The ball tube moving frame double driving mechanism 7 is composed of two groups of ball tube moving frame driving motors 71 and second rolling screws 72. The two ball tube moving frame driving motors 71 are respectively connected to the two second rolling screws 72 through couplings. The ball tube moving frame driving motor 71 drives the second rolling screw 72 to rotate. The two ball tube moving frame driving motors 71 are installed on the top of the first fixed frame 211 through a supporting plate. The two second rolling screws 2 are respectively sleeved with second screw nuts 73. The rotation of the second rolling screw 72 drives the second screw nut 73 to move. The second screw nut 73 is connected to the two second sliders 74 through a connecting plate. The connecting plate is connected to the mounting plate 76 through bolts. The second screw nut 73 is connected to the second sliders 74 through a connecting plate. The second slider 74 is driven to move, and at the same time, the mounting plate 76 is driven to move together, thereby driving the fixed shaft 78 to move up and down. The fixed shaft 78 is rotatably connected to the ball tube moving mechanism 4, which can drive the ball tube moving mechanism 4 to move up and gradually rotate a certain angle. A support shaft 212 is installed above the first fixed frame 211. The two side edges of the ball tube moving frame are respectively hinged to one end of the diagonal support rod 213, and the hinge point is in the middle position of the ball tube moving mechanism 4. The other end of the diagonal support rod 213 is rotatably connected to the support shaft 212. In the process of one end of the ball tube moving mechanism 4 moving up and rotating, the ball tube moving mechanism 4 and the diagonal support rod 213 are rotated, and the ball tube moving mechanism 4 gradually changes from longitudinal to lateral, and the diagonal support rod 213 plays a role of oblique support for the ball tube moving mechanism 4.

[0039] An electromagnet seat 13 is provided at the inner top of the first fixed frame 211, and a plurality of de-energized electromagnets 131 are provided on the electromagnet seat 13. By means of power-on and power-off settings, the de-energized electromagnets 131 can be made magnetic and non-magnetic. When the ball tube moving mechanism 4 is in a vertical state in the first fixed frame 211, the de-energized electromagnet 131 is magnetic and can magnetically attract the ball tube moving mechanism 4 to ensure structural stability. When the state of the ball tube moving mechanism 4 needs to be changed, the de-energized electromagnet 131 is non-magnetic and the ball tube moving mechanism 4 can move smoothly.

[0040] A second fixed frame 221 is provided inside the second fixed frame 22, and the bed panel moving mechanism 6 is installed in the second fixed frame 22 through the second fixed frame 221. The bed panel moving mechanism 6 is a bed panel moving frame, and the bed panel moving frame is driven to move by the bed panel moving frame dual driving mechanism 9 provided in the second fixed frame 221 to achieve position conversion. The bed panel 5 is installed on the outer surface of the bed panel moving mechanism 6.

[0041] The top of the bed panel moving mechanism 6 is connected with a rotating shaft 222, and the rotating shaft 222 is supported by a supporting block fixed on the moving plate 223. When the moving plate 223 moves, it drives the rotating shaft 222 to move, and the rotating shaft 222 drives the bed panel moving mechanism 6 to move. The bed panel moving mechanism 6 can rotate with the rotating shaft 222 at a certain angle while moving. The moving plate 223 is connected to two third sliders 94, and the moving plate 223 and the third sliders 94 move synchronously. The two third sliders 94 move along the two third slide rails 95 respectively. The third guide rails 95 have a guiding function to ensure that the moving plate 223 moves in a straight line. The two third slide rails 95 extend along the length direction of the second fixed frame 221, and the two third slide rails 95 are arranged on both sides inside the second fixed frame 221.

[0042] The third slider 94 and the bed panel moving mechanism 6 are driven to move by the bed panel moving frame double drive mechanism 9. The bed panel moving frame double drive mechanism 9 is composed of two groups of bed panel moving frame drive motors 91 and third rolling screws 92. The two bed panel moving frame drive motors 91 are respectively connected to the two third rolling screws 92 through couplings. The bed panel moving frame drive motor 91 drives the third rolling screw 92 to rotate. The two bed panel moving frame drive motors 91 are installed on the bottom of the second fixed frame 221 through support plates. The two third rolling screws 92 are respectively sleeved with third screw nuts 93. When the third rolling screw 92 rotates, due to space limitations, the third screw nuts 93 can only move linearly along the third rolling screw 92. The moving plate 223 is respectively connected to the two third screw nuts 93 and the two third sliders 94. The third screw nut 93 drives the moving plate 223 to move, thereby driving the bed panel moving mechanism 6 to move, and at the same time driving the third slider 94 to move.

[0043] An axle rod 224 is installed at the bottom of the second fixed frame 221. The middle positions of the two side edges of the bed panel moving frame are respectively hinged to one end of the diagonal support rod 213, and the other end of the diagonal support rod 213 is rotatably connected to the axle rod 224. During the downward movement and rotation of one end of the bed panel moving mechanism 6, the bed panel moving mechanism 6 and the axle rod 224 also rotate a certain angle, so that the bed panel moving mechanism 6 gradually changes from longitudinal to transverse, and the diagonal support rod 213 can have a certain oblique pulling and supporting effect on the bed panel moving mechanism 6.

[0044] A flat plate bracket 10 is movable on the back of the bed panel moving frame, and a filter grid 11 is installed on the flat plate bracket 10. The flat plate bracket 10 is driven by a flat plate bracket driving motor 101 to move along the length direction of the bed panel moving frame. The flat plate bracket driving motor 101 can drive the flat plate bracket 10 to move linearly along the length direction of the bed panel moving mechanism 6, thereby changing the position of the filter grid 11 so as to inspect different parts.

[0045] The flat bracket driving motor 101 is fixedly installed on the bed panel moving frame, and the output shaft of the flat bracket driving motor 101 is connected to the fourth rolling screw 102 through a coupling, and the flat bracket driving motor 101 drives the fourth rolling screw 102 to rotate, and a fourth screw nut 103 is sleeved on the fourth rolling screw 102, and the fourth rolling screw 102 rotates in situ to drive the fourth screw nut 103 to move linearly, and the fourth screw nut 103 is connected to the flat bracket 10 through the fourth screw nut seat 104, and the fourth screw nut 103 The fourth screw nut seat 104 is driven to move, thereby driving the flat panel bracket 10 to move linearly, changing the position of the flat panel bracket 10. The two ends of the flat panel bracket 10 are respectively connected to the two fourth sliders 105. The movement of the flat panel bracket 10 drives the fourth slider 105 to move. The two fourth sliders 105 move along the two fourth slide rails 106 respectively, and have a guiding function to ensure the linear movement of the flat panel bracket 10. The two fourth slide rails 106 extend along the length direction of the bed panel moving frame. The two fourth slide rails 106 are respectively arranged on both sides of the inside of the bed panel moving frame.

[0046] The outer side of the second fixed frame 221 is provided with a limiting device 12, which includes a limiting frame 121, a limiting plate 122 and a limiting pull rod 123. The limiting frame 121 is fixed on the second fixed frame 221, the bottom of the limiting frame 121 is hinged to the limiting plate 122, a limiting shaft is provided above the limiting frame 121, the limiting pull rod 123 is rotatably connected to the limiting shaft, the limiting pull rod 123 is hinged by two pull rods, the limiting pull rod 123 is hinged to the limiting plate 122, and one end of the bed panel moving frame is provided with Through the through hole for one end of the limiting plate 122 to pass through, after the bed panel moving mechanism 6 is transformed into the horizontal direction, the bed panel 5 is on the upper surface of the bed panel moving mechanism 6, so that the examiner can lie flat, and the limiting plate 122 of the limiting device 12 can be unfolded. The limiting plate 122 is composed of two plates with a certain angle. One end of the plate at the top of the limiting plate 122 can be extended into the through hole set on the bed panel moving frame. Through the oblique pulling action of the limiting pull rod 123, one end of the bed panel moving mechanism 6 can be supported, and the structure is more stable.

[0047] Working principle: when the ball tube moving mechanism 4 is arranged in the first fixed frame 211, the ball tube moving mechanism 4 is in a vertical state, the bed panel moving mechanism 6 is in the second fixed frame 221, and the bed panel moving mechanism 6 is also in a vertical state, the ball tube 3 can inspect the person located in front of the bed panel moving mechanism 6, the ball tube driving motor 81 of the single driving mechanism 8 drives the ball tube 3 to move up and down along the ball tube moving mechanism 4, thereby changing the position of the ball tube 3, and the flat plate bracket driving motor 101 drives the flat plate bracket 10 to move up and down along the bed panel moving mechanism 6, thereby changing the position of the filter grid 11, so as to inspect different parts;

[0048] If the examinee needs to lie flat for examination, the two groups of bed panel moving frame driving motors 91 of the bed panel moving frame dual driving mechanism 9 drive the moving plate 223 to move up and down. When the moving plate 223 moves, it drives the rotating shaft 222 to move. The rotating shaft 222 drives the bed panel moving mechanism 6 to move. The upper end edge of the bed panel moving mechanism 6 moves down with the rotating shaft 222, and rotates a certain angle together with the rotating shaft 222. The bed panel moving mechanism 6 and the diagonal support rod 213 also rotate at a certain angle, so that the bed panel moving mechanism 6 gradually changes from longitudinal to transverse. The bed panel 5 is located on the top of the bed panel moving mechanism 6. The examinee can lie directly on the bed panel 5 for examination. The filter grid 11 is still driven by the flat plate bracket driving motor 101 to change its position. The flat plate bracket driving motor 101 can drive the flat plate bracket 10 The ball tube 3 is moved horizontally along the bed panel moving mechanism 6, thereby changing the position of the filter grid 11, so as to inspect different parts. At the same time, the two sets of ball tube moving frame driving motors 71 of the ball tube moving frame dual driving mechanism 7 drive the mounting plate 76 to move upward, and the mounting plate 76 drives the fixed shaft 78 to move upward. The bottom end of the ball tube moving mechanism 4 moves upward along with the fixed shaft 78 and rotates around the fixed shaft 78 at a certain angle. The ball tube moving mechanism 4 and the diagonal support rod 213 also rotate at a certain angle, so that the ball tube moving mechanism 4 is gradually converted from a longitudinal state to a transverse state. The ball tube 3 is located below the ball tube moving mechanism 4. The ball tube 3 is still driven by the single driving mechanism 8. The ball tube driving motor 81 can drive the ball tube 3 to move horizontally along the ball tube moving mechanism 4, thereby changing the position of the ball tube 3, so as to inspect different parts.

[0049] The tube moving mechanism 4 and the bed panel moving mechanism 6 can both be changed from a vertical state to a horizontal state, and the vertical or horizontal inspection mode can be freely switched according to needs. The positions of the first fixed frame 211 and the second fixed frame 221 do not need to be changed. In different states, the position of the tube 3 is changed by the same driving mechanism, and the position of the filter grid 11 is changed by the same driving mechanism to inspect different parts, and the structure is simple. After the inspection mode is switched, there is no need to perform locking operations, which is convenient to use. In both modes, the bed panel 5 can be used in conjunction without the need for cooperation of other mechanisms, and the occupied area is small, thereby improving the space utilization rate.
