Description

  Embodiments described herein relate generally to an assembly assisting apparatus and an X-ray diagnostic apparatus.

  The X-ray diagnostic apparatus has such a size that it cannot pass through the door of the examination room when it is a finished product. Therefore, it is carried into the examination room in a state of being divided into a plurality of units before assembly, and the X-ray diagnostic apparatus is assembled by combining the plurality of units in the examination room. In general, each of the divided units has a mass of 100 kg or more. Therefore, it is difficult to assemble. For example, when assembling by human power, the worker's physical strength is required, and the work is dangerous. Although it is possible to assemble using a jig, the jig becomes a large-scale device. Moreover, much time is required for assembly and disassembly of such a large jig.

More specifically, the assembly assisting device according to the present embodiment moves the lifting target up and down in conjunction with the lifting and lowering of the lifting unit 230 by the driving force generated by the driving device 237. Hereinafter, the assembly assisting device according to the present embodiment will be described in detail with reference to the drawings. The main objects to be lifted according to the present embodiment are the bed part 210 and the X-ray tube holding part 220.

  FIG. 8 is a perspective view schematically showing an assembly assisting device attached to the elevating part 230 and the column part 240. As shown in FIG. 8, at the time of assembly, the support column 240 is installed on the floor surface, and the elevating unit 230 is attached to the support column 240.

  As shown in FIG. 8, the assembly assisting device according to the present embodiment includes an arm 11, a moving body 13, a lifting device 15, and a connection mechanism 17 (not shown in FIG. 8). The arm 11 is a structure having a pillar shape that is detachably attached to the support column 240. The arm 11 is fastened to the upper surface of the support column 240 so that the main axis Ax2 of the arm 11 is parallel to the floor surface and orthogonal to the main axis Ax1. More specifically, the arm 11 is provided so as to be orthogonal to the front surface of the column 241. The arm 11 supports the movable body 13 so as to be slidable along the main axis Ax2. For example, since the arm 11 slidably supports the movable body 13, the movable body 13 and the arm 11 have a structure that can be engaged with each other. Note that the moving body 13 according to the present embodiment does not necessarily need to be fitted into the arm 11 as long as it can slide along the main axis Ax2 of the arm 11. For example, a guide rail for guiding the slide of the moving body 13 to the arm 11 may be formed. In this case, the moving body 13 is fitted into the guide rail so as to be slidable along the guide rail. In addition, in order to perform the following description specifically, it is assumed that the movable body 13 and the arm 11 are engaged with each other.

  The moving body 13 is a structure that slides the arm 11 along the main axis Ax1 and supports the lifting device 15 so as to be movable up and down. More specifically, the moving body 13 and the lifting device 15 are connected via the connection mechanism 17. The connection mechanism 17 will be described later. The lifting device 15 is a structure having a structure to which a lifting object can be attached. For example, the lifting device 15 has a hook shape. In this case, the bed part 210 or the X-ray tube holding part 220 is preferably tied with a woven steel or a steel cord and hung on the lifting device 15.

  FIG. 9 is a schematic diagram of an assembly assisting device that simply shows the connection mechanism 17. As shown in FIG. 9, the connection mechanism connects the lifting / lowering unit 230 and the lifting device 15 in order to lift and lower the lifting device 15 relative to the moving body in conjunction with the lifting / lowering of the lifting / lowering unit 230 with respect to the support column 240. It is a set of machine elements that perform. In other words, the connection mechanism 17 is a power conversion mechanism that converts the lifting / lowering of the lifting / lowering unit 230 caused by the driving force generated by the driving device of the X-ray diagnostic apparatus into the lifting / lowering of the lifting device 15. Specifically, the connection mechanism 17 includes a plurality of pulleys 171 and a wire rope 173. The plurality of pulleys 171 include, for example, a pulley provided on the arm 11 (hereinafter referred to as an arm pulley) 171-1, a pulley provided on the moving body (hereinafter referred to as a moving pulley) 171-2, a lifting device And a pulley 171-3 (hereinafter referred to as a lifting device pulley) 171-3. A groove for guiding the wire rope 173 is formed at the edge of each pulley 171. As shown in FIG. 9, a fixed pulley is used as the arm pulley 171-1 and the moving body pulley 171-2, and a moving pulley is used as the lifting device pulley 171-3. One end of the wire rope 173 is fixed to an arbitrary part of the elevating unit 230. The other end of the wire rope 173 is fixed to the tip of the arm 11. More specifically, the wire rope 173 extends from the fixed end of the elevating unit 230 to the arm pulley 171-1, the first movable body pulley 171-21, the lifting device pulley 171-3, and the second movable body. It is connected to the fixed end of the arm 11 through the pulley 171-2.

  The wire rope 173 may be fixed to the lifting / lowering unit 230 or the arm 11 by any method as long as the lifting / lowering unit 230 does not come off. For example, the wire rope 173 may be bound to a predetermined portion of the lifting unit 230 without any modification to the existing lifting unit 230. Further, a fixing mechanism for fixing the wire rope 173 may be newly provided in the elevating unit 230. For example, a locking part such as a hook may be provided as the fixing mechanism. In this case, the wire rope 173 is fixed to the elevating part 230 by hanging the wire rope 173 on the engaging part.

  Next, the slide of the moving body 13 will be described. FIG. 10 is a diagram for explaining the sliding of the moving body 13. As described above, the moving body 13 is attached to the arm 11 so as to be freely slidable along the main axis Ax2 of the arm 11. Since both ends of the wire rope 173 are fixed, the moving body 13 can be slid along the main axis Ax2 while maintaining the height position of the lifting device 15. For example, when the operator slides the movable body 13 along the main axis Ax2 toward the support column 240, the wire rope portion 173 that connects the first movable body pulley 171-21 and the lifting instrument pulley 171-3. -1 moves downward toward the lifting device pulley 171-3, and the wire rope portion 173-2 connecting the lifting device pulley 171-3 and the second moving body pulley 171-22 is It rises toward the moving body pulley 171-22. Similarly, when the operator slides the moving body 13 along the main axis Ax2 to the side opposite to the support column 240, the wire rope portion 173-2 descends and the wire rope portion 173-1 rises. Therefore, the moving body 13 can be slid along the main axis Ax2 without moving the hoisting tool 15 in the vertical direction.

  Next, the raising / lowering movement of the lifting implement 15 is demonstrated. FIG. 11 is a view for explaining the up-and-down movement of the lifting device. As described above, one end of the wire rope 173 hanging on the lifting instrument pulley (moving pulley) 171-3 is fixed to the elevating unit 230 of the X-ray diagnostic apparatus. Therefore, the lifting device 15 can be raised and lowered in conjunction with the raising and lowering of the lifting unit 230. For example, as shown in FIG. 11, when the elevating unit 230 is lowered by the driving force generated by the driving device of the X-ray diagnostic apparatus, the wire rope 173 is pulled downward by the elevating unit 230, and the lifting device 15 is To rise. Further, when the elevating unit 230 is raised by the driving force generated by the driving device of the X-ray diagnostic apparatus, the wire rope 173 is pulled up by the elevating unit 230 and the lifting device 15 is lowered.

  In the assembly assisting device, the plurality of pulleys 171 have a one-stage configuration. That is, the wire rope 173 fixed to the elevating part 230 is assumed to be directly applied to the arm pulley 171-1. In this case, the moving distance of the lifting device 15 is ½ of the moving distance of the lifting / lowering unit 230. Depending on the specifications of the lifting / lowering unit 230, that is, the movable range of the lifting / lowering unit 230, In some cases, the amount of movement of the instrument 15 cannot be secured sufficiently.

  The plurality of pulleys 171 according to the present embodiment have a multi-stage configuration in order to amplify the movement distance of the lifting device 15 relative to the movement distance of the elevating unit 230. Hereinafter, an assembly assisting device having a multistage configuration will be described.

  FIG. 12 is a diagram schematically showing the configuration of the assembly assisting device according to the present embodiment having a multistage configuration. In addition, in order to clarify arrangement | positioning of the pulley 171, illustration of the arm 11, the raising / lowering part 230, and the support | pillar part 240 is abbreviate | omitted in FIG. As shown in FIG. 12, in order to amplify the moving distance of the lifting device relative to the moving distance in the lifting / lowering section 230, a pulley (hereinafter referred to as a supporting pulley) 171-4 and the lifting / lowering section 230 is added to a pulley (hereinafter, referred to as a lifting unit pulley) 171-5. Specifically, the wire rope 173 is not directly hung on the arm pulley 171-1 from the fixed end on the lifting unit 230 side, but is provided with a plurality of steps of the support pulley 171-4 and the lifting unit. It is hung on the arm pulley 171-1 via the pulley 171-5. For example, in the case of FIG. 12, two support block pulleys 171-4 are provided on the support column 240, two lift unit pulleys 171-5 are provided on the lift unit 230, and the wire rope 173 is on the lift unit 230 side. From the fixed end, the first support block pulley 171-41, the first lift pulley 171-51, the second support pulley 171-42, the second lift pulley 171-52, and the arm It is hung on a pulley 171-1. In this case, when the elevating unit 230 is moved by one unit movement amount, the wire rope 173 from the arm pulley 171-1 to the first moving body pulley 171-21 moves by five unit movement amounts, The instrument 15 moves by 2.5 unit movement. For example, it is assumed that the lifting / lowering movement amount of the lifting / lowering unit 230 is 400 [mm], and the lifting / lowering movement amount of the lifting device 15 required for assembly is 1000 [mm]. In the case of a one-stage configuration, when the elevating part 230 moves by 400 [mm], the moving amount of the lifting device 15 is 1 × 400 = 400 [mm], and the moving amount of the lifting device 15 necessary for assembly is obtained. I can't. However, in the case of the multi-stage configuration of FIG. 12, when the elevating unit 230 moves by 400 [mm], the amount of movement of the lifting device 15 is 2.5 × 400 = 1000 [mm], and the lifting device 15 required for assembly is as follows. The amount of movement can be obtained.

  The attachment positions of the pulleys 171-1, 171-41, and 171-42 are not limited to the above-described example, and may be provided at any position as long as the pulleys 171-1, 171-41, and 171-42 do not move up and down in conjunction with the lifting and lowering of the lifting unit 230. .

  The lifting / lowering movement amount of the lifting / lowering device 15 relative to the lifting / lowering movement amount of the lifting / lowering unit 230 can be arbitrarily designed by increasing or decreasing the number of stages of the pulley 171 as described above. More specifically, the lifting / lowering movement amount of the lifting device 15 with respect to the lifting / lowering movement amount of the lifting / lowering unit 230 is set to 1/2, 3 × 1/2, 5 × 1/2, 7 × 1/2, and the like. n × 1/2 can be designed. Note that n corresponds to the number of pulleys 171. Therefore, it is possible to ensure a sufficient amount of movement of the hoisting tool 15 necessary for assembling, regardless of mechanical restrictions on the amount of movement of the elevating unit 230.

  Next, an assembly flow of the X-ray diagnostic apparatus 100 (more specifically, the X-ray imaging table 200) using the assembly assisting apparatus according to the present embodiment will be described. FIG. 13 is a diagram showing a typical flow of assembling the X-ray diagnostic apparatus using the assembly assisting apparatus according to the present embodiment. Assume that the X-ray diagnostic apparatus is assembled in an examination room.

  First, an operator installs the support | pillar part 240 and the raising / lowering part 230 in a test room in step S1. Specifically, the support column 240 is fastened to the floor surface with a fastener such as a bolt or a nut, and the elevating unit 230 is fastened to the support column 240 with a fastener. In addition, what is necessary is just to fasten the support | pillar part 240 to which this raising / lowering part 230 was attached to a floor surface when the support | pillar part 240 to which the raising / lowering part 230 was attached was carried in to the test room.

  In step S <b> 2, the worker attaches the assembly assisting device according to the present embodiment to the support column 240 and the elevating unit 230. Specifically, as shown in FIG. 8, the worker fastens the arm 11 to which the lifting device 15 and the moving body 230 are attached to the upper surface of the support column 240 with a fastener. Further, for example, as shown in FIG. 12, the worker attaches a plurality of support section pulleys 171-4 to the support section 240 and attaches a plurality of lift section pulleys 171-5 to the lift section. Further, the arm pulley 171-1, the plurality of movable body pulleys 171-2, and the lifting device pulley 171-3 are attached to the arm 11, the moving body 13, and the lifting device 15, respectively. The arm pulley 171-1, the plurality of movable body pulleys 171-2, and the lifting device pulley 171-3 may be initially attached. Then, the operator uses the wire rope 173 as a plurality of lifting unit pulleys 171-5, a plurality of support unit pulleys 171-4, an arm pulley 171-1, a moving body pulley 171-2, and a lifting device pulley. 171-3, one end of the wire rope 173 is fixed to the elevating unit 230, and the other end is fixed to the tip of the arm 11. As described above, in order to amplify the moving distance of the lifting device 15 relative to the moving distance in the lifting / lowering section 230, the number of lifting / lowering section pulleys 171-5 and support section section pulleys 171-4 corresponding to the amount of amplification are provided. It should be done.

The drive device 237 can be operated via an operation board provided on the support column 241 of the support column 240. More specifically, a portable operation device can be connected to the operation board, and an ascending instruction or a descending instruction for the elevating unit 230 can be input via the connected operation device. For example, when the up button is pressed, the operation board repeatedly supplies the up signal to the driving device 237. The driving device 237 moves up and down while the rising signal is supplied. When the ascending button is released, the operation board stops supplying the ascending signal to the driving device 237. In response to the stop of the supply of the rising signal, the driving device 237 stops the elevating unit 230. Similarly, when the lowering button is pressed, the operation board repeatedly supplies a lowering signal to the driving device 237. The driving device 237 descends the elevating unit 230 while the descending signal is supplied. When the lowering button is released, the operation board stops supplying the lowering signal to the driving device 237. In response to the stop of the supply of the descending signal, the driving device 237 stops the elevating unit 230. When the lifting device 15 is lowered to an appropriate height, the operator operates the operation board to tie the bed unit 210 to the lifting device 15 with a wire rope or the like, and operates the driving device 237 to lower the lifting unit 230. As a result, the lifting device 15 is raised to an appropriate height.

  In step S <b> 4, the worker attaches the bed unit 210 to the lifting unit 230. More specifically, first, the operator moves the movable body 13 toward the support column 240 to an appropriate position, operates the driving device 237 and raises the elevating unit 230 to appropriately lift the lifting device 15. Lower to height. Then, the operator fastens the bed part 210 to the lifting part 230 with a fastener or the like.

  In step S5, the operator lifts the X-ray tube holding portion using the assembly assisting device as shown in FIG. Lifting of the X-ray tube holding unit 220 is performed in the same manner as the lifting of the bed unit 210 in step S3.

  In step S <b> 6, the operator attaches the X-ray tube holding unit 220 to the lifting unit 230 as shown in FIG. 16. More specifically, first, the operator moves the movable body 13 toward the support column 240 to an appropriate position, operates the driving device 237 and raises the elevating unit 230 to appropriately lift the lifting device 15. Lower to height. Then, the operator fastens the X-ray tube holding part 220 to the bed part 210 and the lifting part 230 with a fastener or the like. This completes the installation of the unit of the X-ray diagnostic apparatus 100 (more specifically, the X-ray imaging table 200) that requires an assembly auxiliary device for lifting.

  In step S <b> 7, the operator removes the assembly assisting device from the support column 240 and the lifting unit 230.

(Application 1)
In the above embodiment, the arm 11 is fixed to the support column. However, this embodiment is not limited to this. Hereinafter, the assembly assisting apparatus and the X-ray diagnostic apparatus according to Application Example 1 will be described. In the following description, components having substantially the same functions as those of the present embodiment are denoted by the same reference numerals, and redundant description will be given only when necessary.

  FIG. 17 is a perspective view schematically showing the assembly assisting device according to the application example 1 attached to the support column 240 of the X-ray diagnostic apparatus 100. As shown in FIG. 17, the arm 11 is provided on the support column 240 so as to be rotatable only on one side around the main axis Ax1 from the reference angle. Here, the reference angle is defined as an angle around the main axis Ax1 of the main axis Ax2 of the arm 11 in the working state. Specifically, the reference angle is assumed to be an angle at which the main axis Ax2 of the arm 11 is orthogonal to the front surface of the support column 240. Thus, by providing the arm 11 so as to be rotatable about the main axis Ax1, the assembly assisting device can be retracted from the work space for X-ray imaging.

  FIG. 18 is a plan view of the rear end portion of the arm 11 in the working state as viewed from above. As shown in FIG. 18, the working state is a state in which the arm is arranged in a direction orthogonal to the support column 240 toward the working space for assembling the X-ray diagnostic apparatus. That is, the arm 11 is installed at the reference angle in the working state.

  As shown in FIG. 18, support column pulleys 171-43 and 171-44 are added to enable the arm 11 to rotate to one side. Two support block pulleys 171-43 and 171-44 are fixed to the support column 240 near the rear end of the arm 11. Further, the arm pulley 171-1 is fixed to the arm 11. For example, the arm pulley 171-1 is fixed to the opposite side of the fourth support block pulley 171-44 across the main axis Ax2 of the arm 11. A wire rope 173 guided from a lifting unit pulley 171-5 provided in a lifting unit 230 (not shown) includes a third support unit pulley 171-43, a fourth support unit pulley 171-44, and an arm pulley. 171-1 is led to a movable body pulley 171-2 provided on a movable body 13 (not shown). The two support block pulleys 171-43 and 171-44 are immovable with respect to the rotation of the arm 11 around the main axis Ax 1. Therefore, the arm 11 can rotate clockwise with respect to the main axis Ax1, but cannot rotate counterclockwise. More specifically, the two support block pulleys 171-43 and 171-44 may be fixed to the support column 241 of the support column 240 opposite to the rotation direction of the arm 11. For example, in the case of FIG. 18, two support block pulleys 171-43 and 171-44 are provided on the left side when the tip is viewed from the rear end of the arm 11. In this case, the arm 11 cannot rotate counterclockwise (counterclockwise) with respect to the main axis Ax1 due to the interference of the two support section pulleys 171-43 and 171-44. On the other hand, the arm 11 can rotate in the clockwise direction (clockwise) with respect to the main axis Ax1 because there is no object that prevents the rotation. Thereby, the one side rotation mechanism of the arm 11 is implement | achieved.

  FIG. 19 is a diagram illustrating a transition from the working state to the evacuation state. The dotted lines in FIG. 19 indicate the structures of the assembly assisting device in the working state, and the solid lines in FIG. 19 indicate the structures of the assembly assisting device in the retracted state. The retracted state is a state where the arm 11 is retracted from the work space. For example, the arm 11 can be shifted from the working state to the retracted state by pushing the arm 11 in the rotatable direction (in the case of FIG. 19, clockwise with respect to the main axis Ax1).

  Note that the arm 11 can be shifted from the retracted state to the working state by rotating the arm 11 counterclockwise (counterclockwise) by the operator. For example, the arm can be shifted to a working state by providing stoppers around the support block pulleys 171-43 and 171-44 and rotating counterclockwise until the arm 11 contacts the stopper.

  As described above, according to the application example 1, when the assembly assisting device is not used, the arm 11 can be retracted from the work space. Even when the assembly of the X-ray diagnostic apparatus 100 is completed, it is not necessary to remove the assembly assisting apparatus from the X-ray diagnostic apparatus 100. Therefore, the labor of the operator involved in assembly can be reduced.

  Further, since it is not necessary to remove the assembly assisting device from the X-ray diagnostic apparatus 100 even after the assembly of the X-ray diagnostic apparatus 100 is completed, the assembly assisting apparatus can be used for other purposes other than the assembly of the X-ray diagnostic apparatus 100. it can. As another application, for example, the assembly assisting device according to the present embodiment may be used for placing the patient on the bed 210. For example, the arm 11 is usually installed in the retracted state, and when the patient is put on and off, the arm 11 is rotated and installed in the working state. Then, as in the assembly of the X-ray diagnostic apparatus 100, the patient is lifted on the bed using the assembly assisting device, and after the X-ray imaging is completed, the patient is lifted and lowered from the bed using the assembly assisting device. This is useful when the patient is unable to get on and off the bed by himself. After finishing the patient's loading, the operator retracts the arm 11 again. Thereby, the burden of medical workers, such as a nurse and a caregiver accompanying a patient's taking down, can be eased.

As the rotator 31, for example, a structure such as a metal having a disk shape may be used. The rear end of the arm 11 is fixed to the rotating body 31. As the rotator 31 rotates about the main axis Ax1, the arm 11 rotates about the main axis Ax1. As described above, in order to amplify the lifting / lowering distance of the lifting / lowering device 15 relative to the lifting / lowering distance of the lifting / lowering unit 230, a plurality of support block pulleys 171-4 and a plurality of lifting / lowering block pulleys 171-5 are provided in a multi-stage configuration. It has been. Specifically, a plurality of support block pulleys 171-4 are provided on the side surface of the support column part 240, and a plurality of lift unit pulleys 171-5 are provided on the upper surface of the lift unit 230. In the application example 2, the arm 11 has a hollow shape. An arm pulley 171-1 is provided at the rear end of the arm 11. In addition, a plurality of pulleys (hereinafter referred to as “rotary body pulleys”) 171-6 are provided on the outer peripheral surface of the rotating body 31. The wire rope 173 includes a first support pulley 171-41, a first lift pulley 171-51, a second support pulley 171-42, and a second lift from the fixed end of the lift 230 side. It is hung on a pulley 171-52 for a section, a pulley 171-45 for a third support column, and is hung on a plurality of pulleys 171-6 for a rotating body along the outer peripheral surface of the rotating body 31, It is hung on pulley 171-1. The wire rope 173 is fixed to the distal end of the arm 11 from the arm pulley 171-1 via the moving body pulley (not shown) 171-2 and the lifting equipment pulley (not shown) 171-3. Is done. With the above structure, the both-side rotation mechanism of the arm 11 is realized.

  FIG. 22 is a plan view of the rotating body 31 and the support block pulley 171-4 as viewed from above. As shown in FIG. 22, the third support pulley 171-45, that is, the support pulley 171-45 connected to the rotary pulley 171-6 via the wire rope 173, Along with the rotation about the main axis Ax1, it is provided so as to be able to swing around an axis (hereinafter referred to as a swing axis) Ax1 parallel to the main axis Ax1. Specifically, the third support column pulley 171-45 is supported by the pulley support mechanism 35 attached to the side surface of the support column 240 so as to swing around the oscillation axis Ax 3.
