And is supported so as to be slidable only in the front-rear direction of the boom 12. A front moving pulley 32c and a rear moving pulley 32d as front and rear pulley members are attached to the front and rear of the left and right sliders 32aL and 32R so as to be rotatable about a vertical axis.

  Further, the left and right sliders 32aL and R, to which the front and rear moving pulleys 32c and 32d are attached in the front and rear directions, are connected to the counterweight 21 via the link mechanism 33, and the trolley 15 slides in the transverse direction. Has become acceptable. As the link mechanism 33, the support holes 33 d are inserted into the long holes 33 c on both sides formed in the swing arm 33 b as a swing link member that can be rotated by a link support pin 33 a attached near the center of gravity of the counterweight 21. The center portions of the left and right sliders 32aL and R are connected to each other.

  As a result, as shown by the solid line in FIG. 6, the left and right sliders 32aL and R are simultaneously moved, so that the support pin 33d can be moved in a state where the swing arm 33b is set at a right angle in the transverse direction or at a certain angle. The counterweight 21 can be traversed through the long hole 33c, the swing arm 33b and the link support pin 33a, while the left and right sliders 32aL and 32R are differentially moved as indicated by a two-dot chain line in FIG. Thus, the left and right sliders 32aL and 32R can be independently moved on the counterweight 21 within a range in which the swing arm 33b swings in the transverse direction. Then, using the independent movement of the left and right sliders 32aL, 32R on the counterweight 21, only the swinging beam 17c of the swinging mechanism 17 on the trolley 15 is swung.

  The interlocking drive mechanism 30 includes front and rear fixed pulley mechanisms 34 and 35 each having a plurality of fixed pulleys 34a and 35a at the front and rear portions of the boom 12 as a horizontal arm member.

  For example, as shown in FIG. 5, the front and rear fixed pulley mechanisms 34 and 35 have two fixed pulleys 34 a arranged in parallel at the front end corresponding to the left and right sliders 32 aL and R as the front fixed pulley mechanism 34. One fixed pulley 34a is juxtaposed in the vicinity of the turning support portion 11, and five fixed pulleys 35a are juxtaposed at the rear end corresponding to the left and right sliders 32aL and R as the rear fixed pulley mechanism 35. It is. In addition to these, fixed pulleys 34a and 35a are provided as necessary for wiring.

  Further, for the interlock drive by the interlock drive mechanism 30, an operation sheave 17b having grooves in two upper and lower stages is used as an operation pulley member of the swing mechanism 17 on the trolley 15, and the upper end of the swing shaft 17a is used. It is fixed to the part.

  A wire rope 31 as a driving rope member is routed in the movable sheave mechanism 32, the front and rear fixed pulley mechanisms 34 and 35, and the operation sheave 17b of the swing mechanism 17 as follows.

  In this interlocking drive mechanism 30, as shown in FIG. 6, a schematic routing state developed in plan view, basically, the left and right front drive rope members 31 a and 31 a are routed on the front part, and the rear part Similarly, the left and right rear drive rope members 31b and 31b are routed and a total of four wire ropes are used. Here, the front left and right two ropes 31a and 31a are connected to form a single wire. In addition to the rope 31a, the rear left and right two wires 31b and 31b are connected to form a single wire rope 31b.

  First, one of the two front drive rope members 31 a is a front right wire rope 31 a R (corresponding to the upper left wire rope in the figure), and one end is an operation sheave 17 b of the swing mechanism 17. Wrapped around the front sheave 17b itself from the front upper side through the rear side and fixed to the operation sheave 17b itself, and the other end is reversed from the front upper side by the two front fixed pulleys 34a and routed backward. After being wound around the upper side of the front moving pulley 32c of the slider 32aR on the right side of the pulley mechanism 32, it is reversed by the fixed pulley 34a in the vicinity of the turning support portion 11 and moved forward of the slider 32aR on the right side of the moving pulley mechanism 32. It is wound on the lower side of the pulley 32c, routed forward, and fixed to the boom 12.

  Similarly, another one 31a as a front drive rope member is a front left wire rope 31aL (corresponding to a wire rope on the lower left side in the figure), one end of which is on the front lower side of the operation sheave 17b of the swing mechanism 17 From the rear side to the front upper side and fixed to the operation sheave 17b itself, and the other end is reversed from the front lower side by two front fixed pulleys 34a and routed rearward, and the moving pulley mechanism 32 is wound around the upper side of the front moving pulley 32c of the slider 32aL on the left side of 32, and is then reversed by the fixed pulley 34a in the vicinity of the turning support portion 11 so as to be moved on the front moving pulley 32c of the slider 32aL on the left side of the moving pulley mechanism 32. It is wound around the lower side and routed forward and fixed to the boom 12.

  Next, one of the two rear drive rope members 31b is a rear right wire rope 31bR (corresponding to the upper right wire rope in the figure), one end of which is behind the operation sheave 17b of the swing mechanism 17 on the rear upper side. Is wound around the rear sheave 17b through the front side and is fixed to the operation sheave 17b itself, and the other end passes over the counterweight 21 from the upper rear side and is inverted by the two rear fixed pulleys 35a and routed forward. Then, after being wound on the lower side of the rear moving pulley 32d of the slider 32aR on the right side of the moving pulley mechanism 32, it is reversed by the fixed pulley 35a on the rear end portion of the boom 12, and the slider 32aR on the right side of the moving pulley mechanism 32 is rotated. It is wound around the upper side of the rear movable pulley 32d and routed rearward, and further reversed by the fixed pulley 35a at the rear end portion of the boom 12 and routed forward to be fixed to the boom 12.

  Similarly, the other one of the two rear drive rope members 31b is a rear left wire rope 31bL (corresponding to a wire rope on the lower right side in the figure), and one end is an operation sheave 17b of the swing mechanism 17. It is wound around the rear upper side from the lower rear side through the front side and fixed to the operation sheave 17b itself, and the other end passes through the counterweight 21 from the lower rear side and is reversed by the two rear fixed pulleys 35a. And is wound around the lower side of the rear moving pulley 32d of the slider 32aL on the left side of the moving pulley mechanism 32, and then reversed by the fixed pulley 35a at the rear end of the boom 12 so as to be located on the left side of the moving pulley mechanism 32. The slider 32aL is wound around the upper side of the rear moving pulley 32d and routed rearward, and is further reversed by the fixed pulley 35a at the rear end portion of the boom 12 and routed forward and fixed to the boom 12.

  When the front drive rope members 31a and 31a are configured as a single piece, one ends of the front left and right wire ropes 31aL and R are connected to each other, for example, once and half wound around the operation sheave 17b of the swing mechanism 17 The wire ropes 31aL and R may be fixed to the operation sheave 17b in the hung state.

  Similarly, when the rear drive rope members 31b and 31b are configured as a single piece, one ends of the rear left and right wire ropes 31bL and R are connected to each other, and, for example, wound once on the operation sheave 17b of the swing mechanism 17, for example. The wire ropes 31bL, R may be fixed to the operation sheave 17b in the hung state.

  Two rear drive rope members as a drive source for pulling in or feeding out one of the two front drive rope members 31aL, R and the two rear drive rope members 31bL, R Endless winders 36 are interposed in the rear left and right wire ropes 31bL and R, respectively, and the front left and right wire ropes 31aL and R, which are the two front drive rope members, each have an abnormality in the moving speed of the wire rope. A lock device 37 for detecting and automatically gripping and fixing the wire rope is provided.

  Although detailed description of the structure of the locking device 37 is omitted, an abnormal speed is detected by a speed detection roller that sandwiches the wire and a governor mechanism that is driven by this, and this is gripped by sandwiching the wire via the link mechanism. A member configured to operate the member is used.

  In the interlocking drive mechanism 30 configured in this way, the upper and lower two-stage moving pulley members 32c and 32d of the slider 32a provided on the counterweight 21 function as moving pulleys, and when the trolley 15 is traversed, the counterweight 21 moves in the opposite direction by ¼ of the movement amount of the trolley 15.

  For example, from the state shown in FIG. 6, when the rear left and right wire ropes 31bL, R are simultaneously pulled to the same length by two endless winders 36 and the trolley 15 is traversed to the right side in the drawing, When moved, the counterweight 21 moves to the left in the figure via the sliders 32aL, R on the counterweight 21 by the front left and right wire ropes 31aL, R. The front moving pulley 32c of the moving pulley mechanism 32 functions as a moving pulley, and the counterweight 21 moves to the left in the opposite direction by 1/4 of the moving amount of the trolley 15. Then, the slack behind the endless winder 36 of the rear left and right wire ropes 31bL, R generated in this case is moved to the rear moving pulley 32d of the upper and lower two-stage moving pulley mechanism 32 at the rear of the sliders 32aL, R. It is solved by pulling in only twice.

  On the other hand, when the rear left and right wire ropes 31bL and 31R are simultaneously fed out to the same length by the two endless winders 36 from the state shown in FIG. As the wire ropes 31bL and R are pulled backward at the other end, the counterweight 36 is moved to the right. However, the rear moving pulley 32d of the upper and lower movable pulley mechanisms 32 at the rear of the sliders 32aL and R is provided. Functions as a moving pulley, the counterweight 21 moves to the right side by a quarter of this pull-in amount, whereby the front moving pulley 32c of the two-stage moving pulley mechanism 32 in the upper and lower stages of the sliders 32aL and R is moved. The front left and right wire ropes 31aL and R function as a moving pulley and pull in the distance four times. Four times only trolley 15 of momentum will move to the left. Then, the slack on the left side of the endless winder 36 of the rear left and right wire ropes 31bL, R generated in this case is eliminated by the movement of the trolley 15.

  That is, in this interlocking drive mechanism 30, the counterweight 21 is always interlocked in the opposite direction with the movement amount of 1/4 with respect to the movement amount of the trolley 15 by the drawing or feeding of the wire ropes 31a and 31b in the endless winder 36. Can move.

Therefore, according to this interlocking drive mechanism 30, the trolley 15 and the counterweight 21 can be interlocked at different movement ratios (4: 1) in the opposite directions by one mechanism, thereby reducing the weight of the counterweight 21. 4 times the total weight of the trolley 15 and the work cage 16 suspended and supported by the trolley 15 (in practice, there are fluctuations in the suspension load and the weight ratio with the boom, so it is not exactly 4 times the weight). And the movement distance from the turning support 11 that is the fulcrum of the boom 12 of the counterweight 21 is set to ¼ the movement distance of the trolley 15. The work cage 16 can be moved back and forth by the trolley 15 while maintaining the balance of the entire boom 12.
Further, since the position of the counterweight 21 always corresponds to the position of the trolley 15 in a fixed relationship (here, a 4: 1 relationship), the position of the trolley 15 can be known by detecting the position of the counterweight 21. Thus, wiring and the like can be simplified by providing the position detection mechanism of the trolley 15 in the vicinity of the turning support portion 11 of the boom 12.

  The interlocking drive mechanism 30 is configured such that the trolley 15 and the counterweight 21 are interlocked in the opposite directions at a ratio of 4: 1. However, the moving ratio and the fixed pulley are one set, and the movement ratio is 2: 1. Alternatively, the moving ratio of the trolley 15 and the counterweight 21 can be set to be larger by arranging the driving rope members around the three or more sets.

  Further, in this interlocking drive mechanism 30, when the swing mechanism 17 of the trolley 15 is swung to change the direction of the hanging beam 17c, the two endless winder members 36 of the two rear drive rope members 31bL, R are used. Pull in one and operate to pull out the other.

  Therefore, for example, when the rear right wire rope 31bR (upper side in the figure) is pulled in and the rear left wire rope 31bL (lower side in the figure) is extended so that the hanging beam 17c shown by the two-dot chain line in FIG. The slider 32aR on the right side (upper side in the figure) on the weight 21 is moved forward by the front right wire rope 31aR being pulled with the rotation of the operation sheave 17b, and the left side (lower side in the figure) on the counterweight 21. Side) slider 32aL is moved rearward as the rear left wire rope 31bL is pulled in with the rotation of the operation sheave 17b, and is swung around the link support pin 33a of the link mechanism 33 with the counterweight 21. The moving arm 33b simply rotates and slides in the long hole 33c of the swinging arm 33b without moving the counterweight. 32aL, the support pins 33d is moving sliders 32aL of R, it is possible to move the R only can be held to without changing the balance condition without the movement of the center of gravity of the counterweight 21.

  Further, by swinging with the two wire ropes 31a and 31b through the operation sheave 17b of the swing mechanism 17, the operation of the wire ropes 31a and 31b is performed regardless of the swing angle of the hanging beam 17c. It can be swung at a constant speed according to the speed, and the two wire ropes 31a and 31b are wound around the swinging operation sheave 17b, so that the hanging beam 17c is stabilized at any angle. The suspended beam 17c can be held in a stable state and is hardly affected by an external force.

  Furthermore, since the counterweight 21 is set to one and the swing mechanism 17 can be operated by the link mechanism 33 independently of the counterweight 21, the two connected counterweights are compared to the case where the counterweight 21 is configured as two counterweights. Even when one of the wire ropes 31a, 31b is broken, the counterweight 21 can be restrained by the other connected wire rope via the swing arm 33b, thereby preventing the runaway. Can do. Needless to say, even when the four wire ropes 31a and 31b are used without being connected, the counterweight 21 can be prevented from running away via the link mechanism 33.

  Further, since the positions of the sliders 32aL and R on the counterweight 21 are always moved in a constant proportional relationship with the angle of the hanging beam 17c of the swing mechanism 17, the positions of the two sliders 32aL and R with respect to the counterweight 21 are detected. By doing so, the angle of the hanging beam 17c can be known, whereby an angle detection mechanism for detecting the swing angle can be installed in the vicinity of the turning support portion 11, and wiring and the like can be simplified.

  For example, as shown in FIG. 5, two limit switches 38 are installed on the counterweight 21 at both ends of the movement range corresponding to both ends of the swing limit angle of the slider 32a, and this detection signal is input to the control device 39. Then, the endless winder 36 which is a driving source of the swing limit angle alarm and the swing mechanism 17 is automatically stopped.

  Further, a light reflection type distance sensor for detecting the movement of the slider 32a is installed on the counterweight 21 and the swing angle of the hanging beam 17c is set by the swing mechanism 17, so that the detection information of the distance sensor is changed. If the control is performed so as to eliminate the change, the swing angle of the hanging beam 17c when the trolley is traversed can be kept constant while being corrected, and it is automatically used as a working member suspended from the trolley 15. Even when a working device or the like is used, it is possible to stably work in a certain direction while traversing the trolley 15 or turning the beam 12.

  According to such a transverse movement device 10 for the hanging work, it is not necessary to provide the trolley 15 with an operation driving device such as a motor for swinging the hanging beam 17c. There is no need to route cables that supply power.

  Further, since the position of the trolley 15 and the swing angle of the hanging beam 17c can be detected by detecting the movement of the slider 32a on the counterweight 21, the position information is transmitted from the trolley 15 to a control device (not shown) of the traverse moving device 10. This also eliminates the need to route control cables.

  Therefore, there is no need to connect the trolley 15 and the traveling carriage 14 with cables, and as a result, the booms 12 having different lengths can be easily changed only by changing the length of the wire rope as the suspension rope member 19 and the driving rope member 31. It can cope and has extremely high versatility.
