Description

  The present invention relates to an X-ray imaging apparatus having a mechanism for adjusting a wiring length between a moving part and a fixed part connected by a cable, and in particular, even if the necessary cable length changes as the moving part moves. The present invention relates to a technology for storing without loosening.

  For electrical equipment consisting of a moving part and a fixed part connected by a cable, the required cable wiring length may differ depending on the operating position of the moving part, and the wiring length is based on the longest length. Is secured. If the wiring length secured by the operating position of the moving part is not required, the extra length of the wiring is taken out of the electrical equipment, or a storage space for extra wiring is provided inside the electrical equipment. .

  For example, in an X-ray imaging apparatus, a spring balancer is disposed at an upper position of a support for holding an X-ray tube, a roller is provided at a lower position, and a cable connected from the X-ray tube is attached to the roller and the spring balancer. There has been provided a cable processing apparatus having a structure that is held by slackening through a wire with a through ring (see Patent Document 1).

  Conventionally, since the extra length of wiring has been provided outside the X-ray imaging apparatus, the X-ray imaging apparatus occupies extra space and has a problem of detracting from aesthetics. On the other hand, when an extra length of wiring is disposed inside the X-ray imaging apparatus, the wiring may be tangled in a narrow space of the X-ray imaging apparatus, and further, the wiring may be damaged or disconnected. There is a possibility.

  In the present invention, a cable is connected between a moving part and a fixed part, and an intermediate part of the cable is stretched in an S shape with respect to a pulley mechanism in which two pulleys are arranged, and one side of the pulley mechanism. The pulley is configured to be movable in the moving direction of the cable while being urged in the direction opposite to the moving direction of the cable toward the moving portion. Furthermore, the pulley on one side is biased in the direction opposite to the direction of the moving part by a spring force. Alternatively, the pulley on one side is biased in the direction opposite to the direction of the moving portion by the load of the weight attached to the pulley on the one side. Accordingly, the extra length of the cable is folded back and forth so that it is not entangled even in a narrow space.

  The extra length of the cable is folded back and forth by a pulley and the wiring route is determined. Therefore, an X-ray imaging apparatus equipped with a wiring length adjustment mechanism that does not entangle in a narrow space inside the X-ray imaging apparatus. Supply is possible. In addition, since the wiring does not go outside, the aesthetic appearance of the X-ray imaging apparatus is maintained and the operator's work is not disturbed. Furthermore, workability is improved because it is not necessary to consider a margin for the maximum length required for wiring work during installation.

It is a figure which shows schematic structure of the adjustment mechanism of the wiring length by the Example of this invention. It is a figure which shows schematic structure of the adjustment mechanism of the wiring length by the modification of this invention.

  An electric apparatus including a moving unit and a fixed unit connected by a cable according to an embodiment of the present invention relates to an X-ray imaging apparatus, and holds an X-ray tube constituting the moving unit and the X-ray tube. It has a structure consisting of an upper column and a cylindrical column that holds the upper column so as to be vertically movable. The cylindrical support column constitutes the fixed portion and is held so as to be tiltable together with the top plate.

  An X-ray imaging apparatus having a wiring length adjustment mechanism according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing a schematic structure of a wiring length adjusting mechanism according to an embodiment of the present invention. In FIG. 1, an X-ray tube 1 and a column upper part 2 provided with cable guides 2a and 2b constitute a moving part, and a tube provided with a guide 3a, a cover 4, pulleys 6 and 7, and a spring 8. The column-shaped column 3 constitutes a fixed part. The X-ray tube 1 is held at one end of the column upper part 2 and can rotate around the axis of the column upper part 2 (rotation direction α). The upper column 2 is held by a cylindrical column 3 so that it can move up and down (moving direction e). The cylindrical column 3 is laid on the floor so as to be tiltable together with a top plate (not shown), and a cover 4 that is removed for explanation is provided on the cylindrical column 3.

  The cable 5 having one end connected to the X-ray tube 1 is slidably disposed inside the two sets of cable guides 2a and 2b provided on the upper surface of the column upper part 2 and descends along the side surface. It is guided to a rotatable pulley 6 that is introduced into a column-like column 3 and is held movably. Further, the cable 5 is folded back into a U shape by a pulley 6 and guided to a fixed pulley 7, held and fixed by the pulley 7, and the other end is connected to an X-ray generator (not shown).

  The rotatable pulley 6 is held so as to be movable along a guide 3 a formed on the cylindrical column 3, and is urged in a direction opposite to the direction of the column upper portion 2 by a spring 8 attached to the pulley 6. The cable 5 is urged by a force that is ½ of the spring force of the spring 8.

  Since the present invention has the above-described structure, when the required wiring length of the cable 5 is pulled out due to the rotation operation of the X-ray tube 1 or the upward movement of the column upper part 2, the pulley 6 moves upward and wiring is performed. The folded portion is shortened, and the necessary wiring length is secured. On the contrary, when the necessary wiring length is shortened, the pulley 6 moves downward and the extra wiring is folded. Further, even if the wiring length that the pulley 6 moves up and down is changed, the wiring route is determined by the pulley 6 and the pulley 7 and the cable 5 is biased by the spring force, so that the wiring is loosened and entangled. There is nothing.

  In the embodiment shown in FIG. 1, the pulley 6 is biased by a spring 8. Instead, the weight 21, the rope 23 that applies the load of the weight 21 to the pulley 6, and the tubular shape shown in FIG. 2. The present invention can also be applied to a biasing means having a structure including a roller 22 that always causes the force acting on the pulley 6 to be in the direction w even if the inclination angle β of the column 3 changes. 2 are the same as those in FIG. 1 and are not described here.

  The present invention relates to an X-ray imaging apparatus having a mechanism for adjusting a wiring length between a moving part and a fixed part connected by a cable, and in particular, even if the necessary cable length changes as the moving part moves. There is a possibility of using the technology to store without loosening.
