Description

  The present invention relates to an operation device for an article stacking and rotating frame that causes rotational displacement of articles attached to main devices and structures and facilitates work according to the purpose.

  For example, in a high position of a large device or structure (for example, a height of 2 m to several meters), an article or other article or structure that functions in cooperation with the device or structure can be used. In some cases, it may be desirable to attach the object while making it easy to transfer and reposition it. In particular, if the article that you want to easily transfer, reposition, etc. is heavy (for example, 50 kg or more) and is expensive, such as electronic equipment or precision machinery, it depends on the height from the ground. Considering the prevention of breakage of articles and the possibility of accidents involving workers, serious handling and careful handling are required. More specifically, for example, semiconductor manufacturing-related equipment includes, for example, large products with a height of about 2 meters or more above them, and a control device for controlling those devices is further loaded thereon. May be used in the field. In this case, for example, if the main body case height of the coating apparatus as the main body is 2 m and the height of the control device housing case is 1 m, the total height is 3 m, which may be transported and delivered in a set state. The loading and unloading operation of the control device with respect to the coating device is performed, for example, by setting up a stepladder or a scaffolding around the device and sharing the heavy goods while supporting the load while several workers respond. Furthermore, with the control device attached to the main body of these electronic devices and precision machines, the equipment can be loaded on the airplane as it is, and the cargo can be unloaded from the airplane at the destination and moved to be used at the destination factory. When assembling and installing in a state, each time the article side is transferred, repositioned, etc., the work is extremely complicated, and the labor, time, risk of accidents, and work cost during the work are heavy burdens Met. Conventionally, there has been no proposal of a low-cost device that can perform these operations safely and quickly.

  According to the above-mentioned conventional technology, the worker's scaffold is basically unstable, and there is an accident of dropping the operator and dropping an expensive control device when transferring or repositioning the article to the main body side. In addition to concerns, there was a problem that labor and work time were required, and transfer and repositioning work efficiency was inferior. Further, when a dedicated transfer / position change device is manufactured, there is a problem that the device becomes expensive in place of the work contents.

  The present invention has been made in view of the above-described conventional problems, and the object thereof is to transfer, change the position of the article to the main body side in a short time, change the position of the article, or change the attached state. It is providing the operating device of the article | item load | turning rotation frame which can perform. Another object of the present invention is to provide an operation device for an article stacking rotation frame with a simple configuration and low cost.

  In order to achieve the above object, the present invention is such that one end side is pivotally supported at a high position of the main body (26), and the other end side is displaceable between at least a horizontal state and a vertical state while the article 2 is loaded. A rotating frame 12 that rotates in a horizontal direction, a support mechanism 14 that supports horizontal-vertical rotation of the rotating frame 12, and a support mechanism 14 that is directly driven by manual operation from the ground to move the rotating frame 12 horizontally. And a manual operation device 16 for vertical rotation, and an operation device 10 for an article stacking rotation frame. The rotation range of the rotation frame is not limited to a range of 90 degrees from horizontal to vertical, but may be rotated to an arbitrary angle within 360 degrees.

  At that time, the support mechanism 14 is composed of a link operating device 40 constituted by a combination of a plurality of link rods 36 and 37 and an operating rod 38 interposed between the rotating frame 12 and the main body 1. Also good.

  The link operating device 40 has a first and a second one in which one end side is pivotally connected by a common shaft (51) and the other end is pivotally supported by the rotating frame 12 side and the main body 1 side, respectively. Link rods 36 and 37, and an operating rod 38 whose one end is pivotally supported (53) on the main body 1 side and linked to the common shaft (51) to freely change the link angle θ of the first and second link rods. It is good to provide.

  Further, it is more preferable that the operating rod 38 is connected to the common shaft (51) by a screw coupling structure that advances and retracts mutually. The rotary input motion on the hand input side of the operating rod is converted into a linear motion, and the common shaft portion of the link rod is changed so as to open and close the interval between the rotating frame and the main wall. Therefore, no effort is required for the input operation, and the lowering and raising movements on the free end side of the rotating frame can be basically performed by only one operator.

  In addition, the manual operation device 16 transmits the pivoting force of the hand rod to the operating rod regardless of the connection angle of the hand rod 60 connected to and disengaged from the operating rod 38 and the angle of the hand rod with respect to the operating rod. And a universal joint 62 for rotating the operating rod in the direction around the axis.

  Further, it is preferable to provide a lock device 66 that locks the release frame 12 so that the other end side of the rotation frame 12 is displaced in the vertical direction while the article 2 is loaded.

In addition, when the rotating frame 12 is in a horizontal state with the article 2 loaded, the plurality of link rods 36 and 37 are oriented 180 degrees so that the link rods are turned at the manual operator side from the ground. It is good to arrange it in a slightly bent state.

In addition, a straight rod portion 58 having no thread is formed at the tip portion pivoted to the main body 1 side of the operating rod 38, and the longitudinal direction of the operating rod 38 is secured while ensuring a pivotal state with the main body 1 side. The movement is ensured, and it is preferable that the locking and unlocking operation by the lock device 66 is performed through the play movement by the straight bar portion 58 when the rotation frame 12 is locked and released.

  An urging spring is provided so as to apply an urging force in the reverse direction from the main body side at the lower rotation limit position when the free end side of the rotation frame is rotated downward and approaches the lock position. Item 9. A device for operating an article stacking rotation frame according to any one of Items 1 to 8.

  The rotating frame 12 is pivotally supported and assembled in advance with an attachment frame 20 that is attached and fixed to the main body 1, and a plurality of link rods 36 and 37 are provided between the rotating frame 12 and the attachment frame 20. It is preferable to perform an opening / closing operation with respect to the attachment frame.

  According to the operation device for the article loading rotation frame of the present invention, the other end side is pivoted so as to be displaceable at least between the horizontal state and the vertical state while the one end side is pivotally supported at the main position and the article is loaded. A rotating frame, a support mechanism that supports horizontal-vertical rotation of the rotating frame, and a manual operation device that drives the support mechanism directly by manual operation from the ground to rotate the rotating frame horizontally-vertically. For example, even if it is several meters high, without using a stepladder, etc., it can be safely and reliably transferred and repositioned to the main body of the article in a short time, or attached. It is possible to perform state displacement work.

  In addition, the support mechanism is configured by a link operation device configured by a combination of a plurality of link rods and operating rods interposed between the rotating frame and the main body, thereby using a gear connection or the like. In addition, a stable and reliable rotation support of the rotation frame can be realized with a simple structure. In addition, it is possible to realize an operation device for an article stacking rotation frame that is easy to maintain and can be reduced in weight as a whole and has excellent handling properties.

  In addition, the link operating device includes first and second link rods that are pivotally connected to one end side by a common shaft and pivotally supported at the other end side by a rotating frame side and a main body side, respectively, The structure is provided with an operating rod that is pivotally supported on the main body side and that freely links the link angles of the first and second link rods in association with a common shaft, thereby providing a stable and reliable structure with a simple structure. The rotation support of the rotation frame can be realized. In addition, it is possible to realize an operation device for an article stacking rotation frame that is easy to maintain and can be reduced in weight as a whole and has excellent handling properties.

  In addition, since the operating rod is connected to the common shaft by a screw coupling structure that reciprocates with each other, the rotary input is converted into a linear motion, and for example, 100 kg or more can be obtained by a simple operation from the ground. For heavy objects, for example, rotational displacement between a horizontal state and a vertical state can be reliably performed.

  In addition, the manual operation device is connected to the operating rod and detachably connected to the operating rod and transmits the shaft turning force of the proximal rod to the operating rod regardless of the connection angle of the operating rod with respect to the operating rod. By providing a universal joint that rotates the shaft in the direction around the axis, it is possible to specifically realize the rotational input from the hand bag while changing the angle between the rotating frame and the main body. it can.

  In addition, a configuration is provided in which a lock device is provided that locks and releases the rotation frame in a state in which the free end side of the rotation frame rotates while the article is loaded and the article is displaced in the vertical direction. By doing so, for example, the main body and the entire article can be transported in a state of being compacted by pulling the height of the article, which is convenient particularly in the case of aircraft transportation or the like. Since both of them are fixed during transportation, the apparatus can be prevented from being broken or damaged by rattling or the like.

In addition, when the rotating frame is in a horizontal state with an article loaded, the plurality of link rods are slightly bent from the 180 degree direction so that the link rods turn to the manual operator side from the ground. Since the link rods are arranged at 180 degrees, that is, in a straight line, it becomes a resistance during the return rotation of the operating rod and reliably prevents the return rotation operation from becoming difficult. Thus, the return operation can be performed quickly and smoothly.

In addition, the tip part pivoted to the main body side of the operating rod is formed with a straight rod portion without a thread, and the movement of the operating rod in the longitudinal direction is ensured while ensuring the pivotal state with the main body side. In addition, since the lock device is engaged and locked and released through the play movement by the straight bar when the rotating frame is locked and released, for example, when the rotating frame is rotated downward, By setting the limit position and pressing the rotating frame strongly against the main body side from that state, the main body side and the rotating frame, that is, the article side can be semi-fixed, and it is possible to reliably prevent rattling during transportation. Can be prevented.

In addition, a biasing spring is provided so that a biasing force is applied from the main body side in the reverse direction at the lower rotation limit position when the free end side of the rotation frame rotates downward and approaches the lock position. This makes it possible to determine the lower limit of rotation of the rotation frame based on the magnitude of the reaction force to the operator due to the biasing spring force. Can be carried out.

  In addition, the rotating frame is pivotally supported by a mounting frame that is fixedly mounted on the main body side, and a plurality of link rods are interposed between the rotating frame and the mounting frame to open and close the mounting frame. Since the operation is performed, it is advantageous to be able to perform integrated management in production and sales management, and it is also reliable in use, even when there are no components to be connected to the main body side. The device can be used attached to the main body side.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. In this embodiment, for example, a case will be described in which a main device of a semiconductor manufacturing related device is a main body, and an article as a control device is attached to the upper surface of the main body so as to be able to be transferred and repositioned. In this case, the main device and the article are constituted by, for example, a rectangular parallelepiped case or a frame, and the article is placed on a support frame that is partially supported with respect to the main body and rotated at the other end. The support frame that holds the article in this state is displaced from the horizontal state to the vertical state, for example, and the attachment position of the article with respect to the main body is displaced.

In FIG. 1, a main body 1 as a main apparatus is built in a rectangular parallelepiped case frame having a height of about 2 meters, for example, and has a weight of several hundred kilograms, for example. For example, an article 2 as a control device attached thereto has a weight of about 100 kg, for example, and this heavy article is mounted directly above the main body 1 as shown by a broken line in FIG. Used in state. Then, when the main body 1 is transported or moved as necessary, it is rotated and displaced as shown by a solid line in FIG. 1 to a chain line in FIG. 8 so that the entire apparatus can be made compact.

  In FIG. 1, the operation device 10 of the article loading rotation frame according to the present embodiment is a rotation frame that is pivotally supported at one end side at a main position and is rotatable at the other end side (free end side). 12, a support mechanism 14 that supports the rotation of the rotation frame, and a manual operation device 16 that rotates the rotation frame 12 by directly driving the support mechanism 14 by manual operation from the ground. .

  The rotating frame 12 is provided at a position where the main body 1 is set so that it can be rotationally displaced at least from a horizontal state position to a vertical state position by a pivot shaft 18 fixedly attached to the main body 1 side. At that time, the article 2 is displaced on the upper surface side so as not to be detached, and thereby the relative attachment position of the article 2 with respect to the main body 1 can be changed. In the present embodiment, the pivot shaft 18 is attached to one end of the top wall of the main body 1, and the rotating frame 12 is a corner on one end of the top wall and the vertical wall (side wall) of the apparatus case of the main body 1. It is pivotally supported via a mounting frame 20 in the vicinity of the part.

  That is, in FIGS. 1 and 2, the mounting frame 20 is mainly composed of a horizontally long rectangular frame 21 made of a metal frame and a horizontal flange 21 a on one long side of the horizontally long rectangular frame 21 in the vicinity of the high corner of the main body 1. A holding frame 22 that extends to one side and is connected to the horizontal rod at right angles so that both ends of the horizontal rod sandwich the both end walls of the main body 1, and a horizontal frame on the other side of the horizontal rectangular frame 21. And an interval holding rod 23 that extends from the flange 21b to the main body 1 side and sets the distance between the horizontally long rectangular frame 21 and the side wall of the main body 1 to a required distance. The holding frame 22 can be fixed to the other vertical wall side of the main body 1 with bolts 24 in a state where the both side walls of the main body 1 are clamped, and the entire mounting frame 20 is detachably fixed to the main body 1. Is done. A part of the holding frame 22 of the mounting frame 20 is provided with a pivot shaft 18 projecting outward at two locations corresponding to both sides of one side (21a) of the horizontally long rectangular frame 21, and a rotating frame 12 described later. It is inserted into the pin hole on the side. The attachment frame 20 is assembled integrally with the rotation frame 12 in the present embodiment. Functionally, the mounting frame 20 functions as a relay device for pivotally connecting the rotating frame 12 to the main body 1 side. In the case where the pivot connecting portion between the rotating frame and the main body 1 side is directly provided on the main body 1 side, the mounting frame 20 may not be provided in principle.

  In FIG. 1, the rotating frame 12 has at least a free end side mounted in a cantilevered manner with one end side pivoted in a state where the article 2 is locked or semi-fixedly mounted on the upper surface thereof. In this embodiment, one end side is rotated around the mounting frame 20 via the pivot support portion 26 including the pivot shaft 18. It is connected freely.

  In FIG. 2, the rotating frame 12 is configured by a metal substantially square frame having one side having the same length as the long side portion of the horizontally long rectangular frame 21 of the mounting frame 20, and the horizontally long rectangular frame of the mounting frame 20. A mounting area larger than 21 can be secured. Two brackets 27 extending from the frame side to the main body 1 side at right angles to the main body 1 side (projecting upward in FIGS. 1 and 3) are provided at both sides of the one side of the rotating frame 12 near the main body 1 side. It is connected and fixed to the rotating frame 12, and a pin hole 28 is drilled on the distal end side of the bracket 27. Then, the pivot shaft 18 provided on the holding frame 22 of the mounting frame 20 is inserted into the pin hole 28, whereby one side of the rotating frame 12 is pivotally supported at the high position of the main body 1, and the other one side. The free end side of the is rotatably supported. With the pin hole 28 and the pivot shaft 18 fitted in the pin hole 28, the rotation frame 12 is pivoted on the other end (free end) side with respect to the mounting frame 20 in a one-side pivot state. Here, the pivotal support portion 26 is constituted by the pivotal shaft 18 and the pin hole 28. The rotation frame 12 is set so as to be substantially flush with the top wall of the case of the main body 1 when it is in a horizontal state via the rotation support section. In FIG. 1 to FIG. 3, four rollers 30 are supported on shafts and are rotatably mounted on the rotating frame 12, and similar rollers (not shown) are also attached to the top wall of the case of the main body 1. The article 2 placed horizontally on the rotating frame 12 is guided by the roller 30 or the roller on the top wall side from the state on the rotating frame in FIG. It can be moved laterally with respect to the top wall side or the rotating frame side. In the figure, 32 is an operation handle, and 33 is a receiving portion for the article 2, and receives the lower end portion of the article 2 at that time when the rotating frame is tilted to the vertical state as shown in FIG. 8. Further, in the figure, reference numeral 34 denotes a support hook attached to the side closer to the free end (rotation end) of the rotary frame 12, and this support hook 34 has a bent hook portion 35 with the tip portion directed toward the main body 1 side. When the side wall of the article hits the receiving portion 33 after being laterally moved from the main body 1 side, the hook 34 is inserted into the hook receiver of the article 2 (not shown). Thereby, it is possible to smoothly perform the displacement operation from the mounting state of the position directly above the main body 1 to the disengagement position by lateral movement, and further to the position to tilt the article by rotating approximately 90 degrees from that position. . In FIGS. 2 and 3, reference numeral 39 denotes a lock pin attached and fixed to the opposite vertical frame sides of the rotating frame and having a tip projecting outward from the rotating frame 12. Lock engages the lock actuator.

  The support mechanism 14 is a support driving means of a rotation frame that supports the horizontal-vertical rotation of the rotation frame 12 from the stationary position to the entire moving state. In this embodiment, the support mechanism 14 includes a plurality of support mechanisms 14. A link operating device 40 configured by a combination of link rods 36 and 37 and an operating rod 38 is included. Other support mechanisms for the cantilevered pivot frame include a gear occlusion, a rack and pinion, a cylinder mechanism, and the like. By using a combination of a link rod and an actuating rod as in the present embodiment, the structure is simple and low-cost, and the rotation frame can be rotated by a reliable operation.

  In FIGS. 1, 3, and 4, a link operating device 40 is a device that operates a plurality of link-connected link rods to rotate and displace the free end side of the rotating frame 12 supported by them. The link operating device 40 includes first and second link rods 36 and 37 that are pivotally connected at one end side by a common shaft and pivotally supported at the other end side by the rotating frame side and the main body side, respectively. And an operating rod 38 that freely adjusts and changes the link angles of these link rods. 2 and 3, the link operating device 40 of the present embodiment includes left and right link support portions 41 and 42 (right and left in a state of facing the pivoting frame in a tilted state), and these link support portions 41 and 42. And an actuating rod 38 linked simultaneously. The left and right link support portions 41 and 42 include first and second link rods 36 and 37, respectively. The other ends of the left and right first link rods 36 and 36 are pivotally supported at the longitudinal side of the horizontally long rectangular frame 21 of the mounting frame 20 by a pivotal support portion 43 including a pin and a hole, and one end side is a long plate-like shape. It is connected and fixed to both ends of the connecting frame 50. That is, the first link rods 36, 36 and the connecting frame 50 are integrated into a U-shaped frame as a whole. Therefore, both open ends of the U-shaped form the pivotal support 43, and the closed side portion thereof. Is supported so as to be rotatable around the pivot 43.

  The other ends of the left and right second link rods 37 and 37 are pivotally supported at the longitudinal side of the rotating frame 12 by a pivotal support portion 44 made up of a pin and a hole, and one end side is a hole 52 on the second link rod side. Further, pivot pins 51 projecting from both ends of the connecting frame 50 connected to the first link rod are inserted and pivotally attached. As a result, the one end side of the first and second link rods 36 and 37 is indirectly pivotally connected to the common shaft by the pivot pin 51 via the connecting frame 50, and an arbitrary link angle θ is formed between them. In this manner, the engagement angle is continuously changed. In the present embodiment, the first and second link rods are set so that the link angle θ <180 degrees in the entire rotation range of the rotation frame 12 from the horizontal state to the vertical state.

  The operating rod 38 is a link angle changing means that changes the link angle θ in association with the first and second link rods 36 and 37. In this embodiment, the straight rod-shaped operating rod 38 is provided with the pivot pin 51. The link frame 50 that links the first and second link rods 36 and 37 as a common shaft is moved forward and backward with respect to the rotation pivot portion 26 side of the rotation frame, thereby rotating by changing the link angle θ. The frame 12 is rotated around the rotation pivot 26. That is, in the present embodiment, one end side of the operating rod is pivotally supported 53 by the holding frame 22 of the mounting frame 20 and linked to the connecting frame 50. The attachment frame 20 itself is fixedly attached to the main body 1 side by the holding frame 22, and from this point, one end side of the operating rod 38 may be pivotally supported on the main body side. In FIG. 2, one end side of the operating rod 38 is connected to a bearing bracket 54 and a receiving shaft 55 provided on the holding frame 22, and is supported so as to be rotatable about the axis of the receiving shaft 55. The receiving shaft 55 is inserted into the shaft hole of the bearing bracket 54 and is rotatably supported. Further, the receiving shaft 55 passes through the inner hole of the receiving shaft 55, and a stopper stopper 56 is attached to the tip to provide an operating rod 38. ing. The operating rod 38 is connected to the receiving shaft 55 so as to be rotatable about its longitudinal axis. As shown in FIG. 2, the operating rod 38 is provided so as to pass the middle line of the opposite side of the square-shaped rotating frame 12 in a state where the rotating frame is tilted in the vertical direction.

In the present embodiment, the operating rod 38 is connected to the common shaft by a screw coupling structure that advances and retracts mutually. That is, the connecting frame 50 having the common shaft 51 is provided with a through hole drilled in a direction along the longitudinal direction of the operating rod, and is aligned so as to penetrate straight through the hole, and the through hole is formed inside. A screw cylinder 57 having a thread groove on the inner wall is fixed at an intermediate position of the connecting frame 50. On the other hand, in the present embodiment, the operating rod 38 is composed of a long screw bolt that continuously forms a thread around the entire length, and this operating rod penetrates the screw hole of the screw cylinder 57 and is screwed to each other. It is provided so that it can move forward and backward. As a result, the screw cylinder 57 is linearly moved along the operating rod 38 by rotating the operating rod 38 connected to the front end side in the form of a universal joint, for example, from FIG. As shown in FIGS. 4 and 8, the rotation frame 12 is rotated around the rotation pivot 26 while changing the link angle of the link rod. That is, the distal end side of the operating rod is pivotally supported by the universal joint pivot mechanism on the main body 1 side.

As shown in FIG. 2, a straight bar portion 58 having no thread is formed on one end side of the operating rod 38, that is, on a part of the distal end side pivotally supported on the main body side. In the operating rod, the straight bar portion 58 passes through the inner hole of the receiving shaft 55. Therefore, the operating rod 38 can move back and forth in the longitudinal direction with respect to the length range of the straight bar portion 58. As a result, the movement of the working rod in the longitudinal direction is ensured while the pivoting state with the main body side of the working rod 38 is secured. By moving the operating rod in the longitudinal direction, for example, the rotation angle of the link rod is not set to 0 degree, and the state where the rotating frame is tilted to the vertical wall 1a side of the main body 1 is left with a slight link angle. The moving frame tilting operation limit angle is set, and thereafter, the entire rotating frame is further pressed against the vertical wall 1a side of the main body 1 so that the rotating frame can be moved closer to the vertical wall 1a. Thereby, for example, it is possible to perform a locking operation that prevents backlash at the time of conveyance described later.

As shown in FIGS. 1 and 3, in this embodiment, when the rotating frame 12 is in a horizontal state with the article 2 loaded, the link angles of the plurality of link rods 36, 37, that is, the folding angle θ is 180. The angle is set to be smaller than degrees. For example, the angle is set so that the angle is not further increased by a stopper portion (not shown) in a state of a bending angle smaller than 180 degrees. For example, if the link angle is set to 180 degrees and the first and second link rods are set in a substantially linear state so that the rotating frame is in a horizontal state, the free end of the rotating frame from that state is set. This is to prevent the link from being easily broken during the downward rotation return operation on the side and making it impossible to easily operate the rotation direction of the rotation frame.

  In the present embodiment, the manual operation device 16 is a manual operation means that directly drives the support mechanism 14 by manual operation from the ground and rotates the rotation frame 12 horizontally-vertically. A long rod-like operation rod that can be connected is considered. For example, in the above-described embodiment, the operating rod 38 may be formed of an expansion / contraction rod, and may be extended as necessary so that the operator on the ground side operates the extension end side to drive the support mechanism.

In the present embodiment, the manual operation device 16 includes a hand rod 60 connected to the operating rod 38 so as to be detachable, and a second universal joint 62. In FIGS. 1 and 3, a straight rod-like hand rod 60 can be detachably connected to the operating rod 38 via a plug-in joint portion 61. Fix it. By connecting the hand rod 60 to the operating rod 38, the entire length of the operating rod 38 can be substantially extended, and the direct operation can be performed specifically by manual operation of the operator on the ground side. In the present embodiment, in addition to the plug-in joint portion 61, a second universal joint 62 is interposed between the link position with the common shaft of the operating rod and the proximal base portion. Regardless of the connection angle of the hand rod 60 with respect to the operating rod 38, the second universal joint can transmit the shaft turning force of the hand rod to the operating rod and rotate the operating rod around the axis. In particular, when an operator from the ground rotates by hand at a stationary position, it rotates around the main pivot 53 of the operating rod, and the connection angle between the operating rod and the hand rod changes accordingly. As a result, it is possible to smoothly rotate the hand bag. In this embodiment, the insertion receiving cylinder 63 is connected to the side of the hand rod closer to the connection side with the operating rod 38 via the universal joint 62, and operates on the insertion receiving cylinder 63 of the insertion type coupling portion 61 when necessary. It is designed to be used by inserting the base end side of the bag. In the figure, 64 is a handwheel handle attached to the base end side of the hand rod 60, and by manually rotating in the direction indicated by the arrow, the operating rod 38 rotates around the axis via the hand rod. By linearly changing the screwing position between the operating rod and the screw cylinder 57, the link angle θ can be changed and the free end side of the rotary frame 12 can be rotated.

  Further, in the present embodiment, a lock device 66 that locks and locks the state in which the other end side of the rotary frame 12 is displaced in the vertical direction in a state where an article is loaded is provided. The lock device 66 displaces the rotating frame in a substantially vertical state, and when the entire device is conveyed as it is, for example, the main body of the article prevents the main body 1 and the article from colliding with each other due to shaking or vibration. The rotating frame 12 on which the article is loaded is rotated to the free end side of the other end, for example, in the direction indicated by the arrow d in FIG. 3, and reaches near the vertical direction as shown in FIG. Sometimes, the vertically displaced state is locked so as to be locked and released. In the present embodiment, the lock device 66 includes a lock pin 39 on the rotating frame side, and a lock operation device 67 attached to both sides of the vertical side of the horizontally long rectangular frame 21 of the attachment frame 20. In this embodiment, the lock actuating device 67 is a known snap-lock actuating device, and is biased to selectively take two positions of open and closed on the main body 69 as shown in FIG. A snap cam 72 integrally having two claw portions 70 and 71 and a release lever 73 biased to the opening operation preparation position corresponding to the position of the snap cam 72 are provided. A cable 74 such as a chain or string is suspended from the release lever 73, and its lower end is suspended to a position where an operator from the ground can reach. The main body 69 is provided with a concave portion 75, and the concave portion 75 is selectively positioned at either the position where the forked portion of the two claw portions 70, 71 overlaps or the position where it escapes. The snap cam 72 is biased. By positioning and installing the lock pin 39 of the rotation frame so as to enter and exit the recess 75 of the main body, the rotation frame is stopped at the rotation (falling) limit position of the rotation frame by the hand guard 60, and further, the rotation frame is started from that position. By strongly pressing 12 to the vertical wall 1a side, it can be locked by the locking device and fixed in a state where it is tilted to the main body as shown in FIG.

At this time, since the play movement in the longitudinal direction of the operating rod is ensured, the locking device is locked and released through the play movement by the straight bar portion 58 when the rotating frame 12 is locked and released. Can do. 1, 3, and 7, the laterally long rectangular frame 21 of the mounting frame 20 has a biasing force so as to repel the force when the rotating frame 12 is pressed against the main body 1 side, that is, the mounting frame 20 side. A biasing spring 76 is attached to cause The urging spring 76 securely locks the rotating frame 12 by pressing it firmly against the mounting frame side and pulls the rope 74 to the ground side to release the lock. When the rotary frame 12 is turned upright, the repulsive force immediately moves the rotary frame to the rotation lower limit position by the amount of movement, so that the handwheel operation after that can be easily performed. That is, since a plurality of link rods 36 and 37 are provided between the rotating frame 12 and the mounting frame 20 so as to perform an opening / closing operation with respect to the mounting frame 20, it can be produced as a product with improved added value. In addition, manufacturing and sales management is easy, and on-site installation can be performed in a short time and easily.

  Next, the operation of the apparatus of this embodiment will be described. For example, the article 2 such as the control device is conveyed in a vertical state from the usage state of the apparatus of the main body 1 in FIG. The case of moving up is described.

  When the rotating frame is not attached to the main body 1 side, the mounting frame 20 is first bolted to a position near the corner of the main body vertical wall 1a set in advance by marking or the like. In the plug-in joint portion 61 as a detachable joint portion, the hand rod 60 is connected to the operating rod 38, and when the operator M on the ground turns the handle 64 to rotate the hand rod around the axis, the operating rod 38 is operated. Both rotate about the axis and change the link angle θ between the link rods 36 and 37 to rotate the free end side of the rotation frame. Then, the hand bag is rotated so as to increase the link angle, and the rotation frame 12 is made horizontal. Then, the article 2 in FIG. 1 is laterally moved from the chain line to the solid line, the side wall of the article 2 hits the receiving portion 33, and the support hook 34 of the rotation frame is inserted into the article 2 side to The article 2 is placed in a hook-locked state. When the article 2 is laterally moved, it can be easily moved by a simple operation by rolling of the roller on the lower surface side. When the article 2 is correctly arranged on the main body 1, the holding frame 22 of the mounting frame 20 is removed from the main body 1, and the entire operating device is detached from the main body, so that the intended driving operation or use is performed. When these main body 1 and article 2 are transported and moved, an operation reverse to the above is performed. First, the mounting frame of the operating device is bolted to a position near the corner of the vertical wall 1a of the main body 1 to connect the hand rod 60 and the operating rod 38, and the handle 64 of the hand rod is rotated around its axis to rotate the rotating frame 12. Is protruded laterally from the corner of the main body 1 and held in a horizontal state. In this state, the article 2 is slid in the horizontal direction, transferred onto the rotating frame, and locked. In this state, when the operator on the ground turns the handle 64 of the hand basket 60 from the state shown by the solid line in FIG. In the direction opposite to the axis, and the link angle θ between the link rods 36 and 37 is changed to be an acute angle so that the free end side of the rotating frame is lowered (counterclockwise at the rotating pivot). Rotate in the rotation direction). At this time, the long screw portion of the operating rod 38 and the screw cylinder 57 fixed to the connecting frame 50 are screwed together, and the screw cylinder moves linearly along the operating rod. Since the pivot 53 is pivotally supported on the main body side, the rotating frame is lifted and rotated (with the pivoting pivot at the pivotal support portion) in a state in which the rotation on the free end side of the rotating frame is securely supported with a light load. (Clockwise direction) and downward rotation can be performed. Moreover, this operation itself can be realized by one worker from the ground. When reaching the lower limit of rotation by the handle operation as shown in FIG. 5, the handle becomes heavy and difficult to rotate even if it is turned further. At this time, as shown in FIG. 5, the interval between the vertical wall 1a of the main body 1 and the rotation frame is set to be large, for example, on the lower end side of the rotation frame, and the rotation frame is attached at this rotation limit position. It is set so as to hit an urging spring 76 provided on the frame side. In this state, when the operator grips the operation handle 32 of the rotating frame 12 and strongly presses it against the vertical wall 1a against the elastic force of the biasing spring 76, the straight bar portion 58 at the tip of the operating rod 38 is The free pivot support 53 moves in the direction a, and the free end side of the rotation frame moves toward the vertical wall 1a. At this time, as shown in FIG. 7, when the lock pin 39 of the rotation frame 12 hits and pushes the claw portion 71 on the back side of the lock operating device 67, the snap cam 72 is counterclockwise via the support shaft 68. At this time, the lock pin 39 is fitted in the concave portion 75 of the main body, and the snap cam 72 is spring-biased at the position indicated by the chain line from the solid line in FIG. Here, in the state of FIG. 8, the article 2 can be securely fixed to the main body 1 side to reduce the overall height of the apparatus, and can be safely and reliably conveyed and moved in a compact state.

  When returning the article 2 to the position just above the main body 1 again at the destination, when the operator pulls the rope 74 downward, the release lever 73 moves the snap cam 72 to the open side to lock it. Is released, and the rotating frame 12 is immediately displaced to the rotation limit position of FIG. 5 by the elastic force of the urging spring 76. In this state, the hand bag 60 is again connected to the operating rod and rotated, and the link frame is operated so as to enlarge the link angle, thereby returning the rotating frame to the horizontal state shown in FIGS. Can do. From this, the article 2 can be easily transferred to the position directly above the main body 1 by simply moving the article laterally. Since the link frame has a link angle θ <180 degrees at the horizontal position of the rotary frame, when the free end side of the rotary frame is lowered and rotated from this state, the screw on the common shaft 51 portion is screwed. There is no resistance to screwing back and forth between the cylinder and the threaded portion of the operating rod, and it can be reliably rotated with a light operation. In particular, when lowering and turning the free end of the rotating frame, the handle operation of the operator's hand on the ground side is almost unloaded, and the lowering operation can be performed in a short time without requiring labor. Is possible.

  In the above embodiment, since the pivot frame 12 and the mounting frame 20 are pivotally connected and assembled in advance in the pivot pivot portion 26, product manufacture, management, sales management, on-site installation, This is advantageous for work management including removal.
