The Z direction indicates the vertical direction, the Z1 side indicates the lower side in FIG. 2, and the Z2 side indicates the upper side in FIG.

  FIG. 1 is a plan view showing a configuration of a slide rail type overhead crane device 10A according to a first embodiment of the present invention. FIG. 2 is a front view showing the configuration of the slide rail type overhead crane device 10A shown in FIG. FIG. 3 is a side view showing the configuration of the slide rail type overhead crane device 10A shown in FIG. As shown in FIGS. 1 to 3, the slide rail type overhead crane device 10 A includes a traveling rail 20, a trolley mechanism 30, a connecting beam 60, a slide rail 70, a rail drive device 80, and a rail follower device 100. , An electric hoist 110, a mounting frame 120, and a hoist traveling device 130. The trolley mechanism 30 is a device called a traveling saddle or an end track, and the hoist traveling device 130 is a device called a traversing device or a traversing trolley, but in the present specification, it is called a trolley mechanism and a hoist traveling mechanism, respectively.

  The traveling rail 20 uses, for example, H steel, and is attached to a ceiling in a facility such as a factory via supporting members 25 arranged at appropriate intervals. In the traveling rail 20, the upper flange 21 side is fixed to the support member 25 and the trolley mechanism 30 is supported by the lower flange 22 side. Although two traveling rails 20 are provided in the configuration shown in FIGS. 1 and 2, the two traveling rails 20 are spaced apart from each other by a sufficient distance corresponding to the length of the slide rail 70. They are arranged parallel to one another. The lower flange 22 corresponds to the first traveling portion.

<About the trolley mechanism>
FIG. 4 is a plan view showing the configuration of the trolley mechanism 30 provided in the slide rail type overhead crane device 10A shown in FIG. FIG. 5 is a front view showing the configuration of the trolley mechanism 30 shown in FIG. The trolley mechanism 30 shown in FIGS. 4 and 5 is disposed on the other side (X2 side) in the transverse direction (X direction). As shown in FIGS. 4 and 5, the trolley mechanism 30 has a pair of saddle frames 31 and 32, a trolley drive mechanism 35, and a bouncing mechanism 42. Among these, the pair of saddle frames 31 and 32 are portions that support the trolley drive mechanism 35 and the anti-spring mechanism 42.

  The pair of saddle frames 31, 32 extend so that the Y direction is the longitudinal direction, but the length of the pair of saddle frames 31, 32 is the two slide rails 70 in the front-rear direction (Y direction) It is provided longer than the arranged dimension. More specifically, as shown in FIG. 1, the trolley drive mechanisms 35 are respectively disposed outside the opposing portions of the pair of connection beams 60. That is, the trolley drive mechanism 35 on the front side (Y1 side) is disposed on the front side (Y1 side) with respect to the connection beam 60 on the front side (Y1 side). In addition, the back side (Y2 side) trolley drive mechanism 35 is disposed further to the back side (Y2 side) than the connection beam 60 on the back side (Y2 side). Thereby, the trolley drive mechanism 35 can be disposed on the front side (Y1 side) and the rear side (Y2 side).

  The pair of saddle frames 31 and 32 are connected to each other by a pair of connecting members 33 and 34. The pair of coupling members 33 and 34 rigidly connect the saddle frames 31 and 32 on the lower side (Z 2 side) of the lower flange 22. In the configuration shown in FIG. 4, the pair of coupling members 33 and 34 are L-shaped steels, and the front (Y1 side) and the rear (Y2 side) of the pair of saddle frames 31 and 32 in the front-rear direction (Y direction) Each is connected by).

  The trolley drive mechanism 35 further includes a drive motor 36, an inner wheel portion 37, an inner meshing gear 43, a drive transmission shaft 44, an outer meshing gear 46, and an outer wheel portion 47. The drive motor 36 is a portion that provides a driving force for the trolley mechanism 30 to move (travel) along the traveling rail 20. For example, a geared motor having a built-in reduction gear can be used. May be used.

  Further, the inner wheel portion 37 has an inner rotation shaft 38, an inner hub 39, an inner drive wheel 40, and an inner large diameter gear 41. The driving force of the drive motor 36 described above is transmitted to the inner large diameter gear 41 via a gear, and the inner drive wheel 40 and the inner large diameter gear 41 are attached to the inner rotation shaft 38 so as to rotate integrally. There is. In the configuration shown in FIG. 5, the tire 40a is attached to the large diameter portion 39a on the X1 side of the inner hub 39 and the small diameter portion 39b on the X2 side to form the inner drive wheel 40. The inner large diameter gear 41 meshes with the inner meshing gear 43 so as to transmit the driving force, and the transmitted driving force is transmitted to the outer meshing gear 46 via the drive transmission shaft 44, and the outer meshing gear 46 is the outer wheel The driving force is meshed with the outer large diameter gear 51 of the portion 47 so as to be transmittable. Thereby, the driving force of the drive motor 36 is transmitted to the outer wheel portion 47. Although the inner large diameter gear 41 and the inner meshing gear 43 correspond to the driving force transmission mechanism, the driving force transmission mechanism may have a configuration other than these.

  Among these, the inner drive wheel 40 and the outer drive wheel 50 are portions that rotate in a state of being in contact with the upper surface side of the lower flange 22 of the traveling rail 20, and the trolley mechanism 30 is moved along the traveling rail 20 by its rotation. Moving.

  Further, the inner large diameter gear 41 is a portion that transmits the driving force to the bounce mechanism 42, but may play a role as a flange that prevents positional displacement with respect to the lower flange 22 of the inner drive wheel 40. In the present embodiment, the side rollers 33a and 34a attached to the coupling members 33 and 34 so as to rotate along the lower flange 22 prevent positional deviation in the lateral direction (X direction). Further, the bounce prevention mechanism 42 has an inner meshing gear 43, a drive transmission shaft 44, and a bounce prevention roller 45. The inner meshing gear 43 is a portion that meshes with the inner large diameter gear 41 described above. Further, the inner meshing gear 43 is attached to one side (X1 side) of the drive transmission shaft 44. The drive transmission shaft 44 is a rotating shaft that rotates integrally with the inner meshing gear 43, and is a portion that mounts the anti-collision roller 45 and the outer meshing gear 46 and rotates integrally with these. The inner large diameter gear 41 and the drive transmission shaft 44 are part of the components of the bouncing mechanism 42, but simultaneously constitute (or share) the components of the trolley drive mechanism 35.

  The bounce prevention roller 45 is a wheel that abuts on the lower surface side of the lower flange 22 of the traveling rail 20. The bounce roller 45 may not normally be in contact with the lower surface side of the lower flange 22. However, when the trolley mechanism 30 is lifted by the rotation of the connection beam 60 or the like, thereby raising the inner large diameter gear 41 from the upper surface of the lower flange 22 (lift), the anti-spring roller 45 is It abuts on the lower surface side of the lower flange 22. As a result, the trolley mechanism 30 can be prevented from slipping and losing the traveling drive force, and the drive force transmission mechanism can stably move along the traveling rail 20.

  For example, as shown in FIG. 2, in the state where the slide rail 70 largely protrudes from the traveling rail 20 on one side to one side (X1 side) in the transverse direction (X direction), one end side (X1) of the slide rail 70 Consider the case where the electric hoist 110 is present on the side) and the load is lifted. At this time, the slide rail 70 may rotate with the trolley mechanism 30 positioned on one side (X1 side) of the two traveling rails 20 as a fulcrum. At this time, the other end side (X2 side) of the slide rail 70 tries to rotate so as to lift the connecting beam 60, whereby the other end side (X2 side) of the connecting beam 60 is also a trolley mechanism 30. Try to pivot to lift the As a result, in the other end side (X2 side) trolley mechanism 30, the inner drive wheel 40 may be lifted (away) from the upper surface of the lower flange 22.

  However, even when the inner drive wheel 40 floats up from the upper surface of the lower flange 22 and the inner drive wheel 40 idles, the bounce roller 45 abuts on the lower surface side of the lower flange 22. As a result, it is possible to apply a driving force for the bouncing mechanism 42 to travel along the traveling rail 20 via the bouncing roller 45. Therefore, the trolley drive mechanism 35 and the anti-spring mechanism 42 cooperate to cause the trolley mechanism 30 to travel along the traveling rail. This prevents oblique travel and impossibility of traveling of the slide rail type overhead crane device 10A and enables stable traveling.

  Here, “to cooperate” means traveling (driving) along the traveling rail 20 while the inner drive wheel 40 or the outer drive wheel 50 corresponding to the drive wheel and the springing mechanism 42 complement each other. Say what to do. Therefore, when the inner drive wheel 40 and the outer drive wheel 50 corresponding to the drive wheels are in contact with the upper surface of the lower flange 22, the trolley mechanism 30 is driven by the rotation drive of the inner drive wheel 40 and the outer drive wheel 50. Drive along 20. On the other hand, when the bouncing mechanism 42 is in contact with the lower surface of the lower flange 22, the trolley mechanism 30 travels along the traveling rail 20 by the rotational driving of the bouncing mechanism 42.

  The bounce prevention roller 45 is provided to have the same diameter as the inner drive wheel 40 and the outer drive wheel 50. This makes it possible to share parts. Furthermore, for example, if the number of teeth of the large internal diameter gear 41 and the internal meshing gear 43 is the same, the speed at which the trolley mechanism 30 travels in a state where the bounce roller 45 abuts on the lower flange 22 is the inner drive wheel 40 and With the outer drive wheel 50 in contact with the lower flange 22, the speed at which the trolley mechanism 30 advances can be made the same. As a result, even when one of the trolley mechanisms 30 is lifted, it is possible to maintain a good running balance on the left and right. However, the inner drive wheel 40 and the outer drive wheel 50 may not have the same diameter, and the number of teeth of the inner large diameter gear 41 and the inner meshing gear 43 may not be the same.

  Further, an outer meshing gear 46 is attached to the other side (X2 side) of the drive transmission shaft 44. The outer meshing gear 46 is a gear similar to the inner meshing gear 43, and is meshed with the outer large diameter gear 51 of the outer wheel portion 47. In addition to the above-described large-diameter gear 51, the outer wheel portion 47 also has an outer rotation shaft 48 similar to the inner rotation shaft 38, an outer hub 49 similar to the inner hub 39, and an outer drive similar to the inner drive wheel 40. Wheels 50 are provided. The outer hub 49 is provided with a large diameter portion 49a similar to the large diameter portion 39a, and further provided with a small diameter portion 49b similar to the small diameter portion 39b. The outer drive wheel 50 is also provided with a tire 50a similar to the tire 40a. The inner drive wheel 40 and the outer drive wheel 50 correspond to drive wheels.

  Further, as shown in FIG. 4, the trolley drive mechanism 35 is also provided with an inner driven wheel 52 which is a component of the inner wheel portion 37 and an outer driven wheel 53 which is a component of the outer wheel portion 47. Therefore, four wheels are present in the trolley drive mechanism 35. Such a trolley drive mechanism 35 is provided on the front side (Y1 side) and the rear side (Y2 side) in the extending direction (Y direction) of the traveling rail 20, so that the trolley mechanism 30 can be connected to the connecting beam 60 or the slide rail 70. And the like, and can stably travel along the traveling rail 20 while supporting a load such as.

  Such a trolley mechanism 30 is supported by the traveling rail 20 on the other side (X2 side) in the transverse direction (X direction) of the two traveling rails 20 as apparent from FIGS. 1 and 2. On the other hand, as apparent from FIGS. 1 and 2, the trolley mechanism 30 is also disposed on the traveling rail 20 on one side (X1 side) in the transverse direction (X direction) of the two traveling rails 20. However, the trolley mechanism 30 located on one side (X1 side) in the transverse direction (X direction) has a configuration obtained by removing the bounce prevention roller 45 from the configuration shown in FIG. It is attached to the side (X2 side), but other than that becomes the same constitution. Therefore, the description is omitted.

<About connected beam>
Next, the connection beam 60 will be described. As shown in FIG. 1, two connecting beams 60 are fixed to the saddle frame 31. The connection beam 60 is provided to increase the sliding range of the slide rail 70 described later, and maintains the integrity in traveling of the trolley mechanism 30 disposed in each of the lateral directions (X direction), It is for preventing skewing.

  The two connecting beams 60 are connected to each other by an intermediate stay 61 in the middle thereof. Thereby, the rigidity is improved while maintaining parallelism along the entire longitudinal direction (X direction) of the connection beam 60. Further, since the trolley mechanism 30 is rigidly connected to both ends of the connection beam 60, it is possible to prevent skewing of the trolley mechanism 30. Since the rail drive device 80 for sliding the slide rail 70 is attached to the connecting beam 60, in addition to the strength for preventing the skewing of the trolley mechanism 30, the connecting beam 60 also has the strength for supporting the load applied to the slide rail 70. Have. Therefore, the lower end of the connecting beam 60 is substantially the same as the lower ends of the saddle frames 31 and 32 of the trolley mechanism 30, and the upper end of the connecting beam 60 is located above the upper ends of the saddle frames 31 and 32. In the present embodiment, the upper flange 21 of the traveling rail 20 is located above the upper ends of the saddle frames 31 and 32, and the upper end of the connection beam 60 is located above the upper end of the upper flange 21.

<About slide rail>
Next, the slide rail 70 will be described. As shown in FIGS. 1 and 2, the slide rail 70 slides relative to the trolley mechanism 30 and the connection beam 60, but the slide rail 70 is a rail drive 80 attached to the trolley mechanism 30 or the connection beam 60. Is slid in the transverse direction (X direction). As shown in FIG. 3, the slide rail 70 uses, for example, an H-shaped steel, and is suspended from the rail drive device 80 on the lower surface side on the upper flange 71 side. The upper surface of the lower flange 72 of the slide rail 70 travels along the slide rail 70 so that the wheels of the electric hoist 110 described later travel.

  As shown in FIG. 1, end stays 73 and 74 are attached to both ends of the slide rail 70 in the longitudinal direction (X direction). Thereby, the width between the two slide rails 70 is prevented from changing, and the two slide rails 70 slide integrally.

<About rail drive device>
Next, the rail drive device 80 will be described. The rail drive device 80 corresponds to a part of the rail transport mechanism. FIG. 6 is a view showing a configuration of the rail drive device 80 provided in the slide rail type overhead crane device 10A shown in FIG. 1 and a view from the front of the slide rail type overhead crane device 10A. FIG. 7 is a plan view showing the configuration of the rail drive device 80 shown in FIG. The rail drive device 80 shown in FIGS. 6 and 7 is attached to the trolley mechanism 30 on one side (X1 side) in the transverse direction (X direction). Therefore, the positional relationship in the transverse direction (X direction) is opposite to the configuration of the trolley mechanism 30 shown in FIGS. 4 and 5.

  The rail drive device 80 includes a pair of support frames 81 and 82, which are connected and fixed to the saddle frames 31 and 32 of the trolley mechanism 30 while being connected to each other on the upper side of the upper flange 71. The rail drive device 80 includes a drive motor 83, a pair of drive wheel portions 84 and 85, and a pair of driven wheel portions 87 and 88, in addition to the pair of support frames 81 and 82.

  The drive motor 83 is attached to the support frame 81 in the configuration shown in FIG. The drive motor 83 is a portion for applying a drive force to slide the slide rail 70. For example, a geared motor having a built-in reduction gear like the drive motor 36 may be used, but other motors may be used. good.

  Further, a pair of drive wheel portions 84 and 85 are also rotatably attached to the support frame 81. The pair of drive wheel portions 84 and 85 are provided in the same shape as each other, and these adopt the same configuration as the inner wheel portion 37 and the like described above. Specifically, the pair of drive wheel portions 84 and 85 includes drive shafts 84 a and 85 a corresponding to the inner rotation shaft 38, drive hubs 84 b and 85 b corresponding to the inner hub 39, and drive corresponding to the inner drive wheel 40. The wheels 84 c and 85 c and transmission gears 84 d and 85 d corresponding to the inner large diameter gear 41 are provided. Further, large diameter portions (reference numerals omitted) of the drive hubs 84b and 85b are transmission gears 84d and 85d. The driving wheels 84c and 85c correspond to an example of the wheels.

  In addition, although it is set as the structure which does not attach a tire, the small diameter part (code | symbol abbreviation | omission) of drive hub 84b, 85b may employ | adopt the structure which attaches a tire. Further, the transmission gears 84d and 85d function as flanges for preventing the drive wheels 84c and 85c from coming off the lower flange 72, similarly to the inner large diameter gear 41 and the like.

  The driving force of the driving motor 83 described above is transmitted to the transmission gear 84d through the gear, and the driving wheel portion 84 is rotated. Here, an intermediate gear 86 is disposed between the drive wheel portion 84 and the drive wheel portion 85, and the intermediate gear 86 meshes with both the transmission gear 84d and the transmission gear 85d. Therefore, when the drive wheel unit 84 is rotated, the drive wheel unit 85 is also rotated in the same direction at the same rotational speed. Thereby, the rail drive device 80 provides a driving force to slide the slide rail 70.

  On the other hand, on the support frame 82 opposite to the support frame 81 in the width direction (Y direction) of the slide rail 70, a pair of driven wheel portions 87, 88 is rotatably supported. The pair of driven wheel portions 87 and 88 are driven to rotate in a driven manner, and have a configuration similar to that of the inner driven wheel 52 and the like described above. For this reason, although the rail drive device 80 is also configured to have four wheels, the drive wheel portions 84 and 85 for applying a driving force for sliding the slide rail 70 are one side of the slide rail 70 in the width direction (Y1 Side only exists.

  However, as is apparent from FIG. 1, there are two slide rails 70, and the opposite slide rail 70 is also provided with a rail drive device 80. The rail drive device 80 in the slide rail 70 on the opposite side has a positional relationship in the Y direction opposite to that shown in FIG. Therefore, when the two slide rails 70 slide, the slides are stable without deviation.

  As shown in FIGS. 6 and 7, side rollers 89 are rotatably attached to the support frames 81 and 82 at both ends in the extending direction. The side roller 89 rotates along the side surface of the upper flange 71 and is a member that guides the slide rail 70 to move smoothly by the rail drive device 80.

  Further, as shown in FIGS. 1 and 2, a rail driving device 80 is provided also in the middle of the connection beam 60, and the driving wheel portions 84 and 85 are in contact with the lower surface side of the upper flange 71 of the slide rail 70. I am in touch. FIG. 8 is a view showing the rail drive device 80 in the middle part of the connection beam 60 provided in the slide rail type overhead crane device 10A shown in FIG. 1 and a view from the front of the slide rail type overhead crane device 10A. .

  In addition, the traveling rail 20 is not arrange | positioned in the middle part of the connection beam 60 shown in FIG. 8, therefore the trolley mechanism 30 does not exist, either. Therefore, in the rail drive device 80 existing in the middle part of the connection beam 60, the support frames 81 and 82 are fixed to the web 63 of the connection beam 60. Therefore, the rail drive device 80 shown in FIG. And slightly different. Specifically, in the configuration shown in FIG. 8, the arrangement position of drive motor 83 in rail drive device 80 is different from the configuration shown in FIG. 6, and is arranged between drive wheel portion 84 and drive wheel portion 85. As a result, the driving force of the driving motor 83 is transmitted to the transmission gears 84 d and 85 d through the gears, and the intermediate gear 86 is omitted. However, since the configuration other than these is the same as that of the rail drive device 80 shown in FIG. 6, the description of the details will be omitted. Further, the configuration shown in FIG. 8 is different from the rail drive device 80 shown in FIG. 6 in that the bounce prevention mechanism 90 is disposed to face the rail drive device 80.

<About the bounce mechanism>
As shown in FIG. 8, on the upper surface side of the rail drive device 80 and the upper flange 71, a bouncing mechanism 90 is disposed. The bounce mechanism 90 corresponds to the second bounce mechanism. FIG. 9 is a plan view showing the configuration of a bouncing mechanism 90 provided in the slide rail type overhead crane device 10A shown in FIG. The bounce prevention mechanism 90 holds the lifting from the drive wheel portions 84 and 85 due to the rotation of the slide rail 70, while the other end side (X2 side) of the slide rail 70 in the longitudinal direction (X direction) is below the connection beam 60. It is a portion that contacts the flange 62 or the trolley mechanism 30 to prevent running resistance.

  The spring stop mechanism 90 is attached to a lower flange 62 of the H-shaped steel connection beam 60 and a recess 64 in which the web 63 is cut out. Even when the lower flange 62 and a part of the web 63 are cut away, the concave flange 64 has a curved flange 65 covering the upper outer periphery of the spring stop mechanism 90 in order to reinforce and maintain the strength of the connecting beam 60. A portion of the web 62 and the web 63 facing the cutout 64 is fixed by welding or the like.

  As shown in FIGS. 8 and 9, the bouncing mechanism 90 mainly includes a pair of holding plates 91 and 92, a support shaft 93, and a bouncing roller 95. The pair of holding plates 91 and 92 are respectively disposed on the upper surface (the surface on the Y1 side) and the lower surface (the surface on the Y2 side) of the web 63 and via a connector 96 such as a bolt that penetrates the web 63. The pair of holding plates 91 and 92 are connected to each other. Thereby, the whole of the bounce mechanism 90 is attached to the web 63.

  Further, a support shaft 93 is attached to the pair of holding plates 91 and 92. A spring stop roller 95 is rotatably attached to the support shaft 93 via a bearing 94. The bounce roller 95 corresponds to a second bounce roller. As shown in FIG. 8, the bounce prevention roller 95 protrudes downward (Z 2 side) from the lower flange 62 of the connection beam 60 and abuts on the upper flange 71 of the slide rail 70. Thereby, the floating from the drive wheel portions 84 and 85 due to the rotation of the slide rail 70 is suppressed. The bounce prevention roller 95 may be disposed so as to have a slight gap without contacting the upper flange 71.

<About rail follower>
Next, the rail follower 100 will be described. The rail follower 100 corresponds to a part of the rail conveyance mechanism. As shown in FIG. 1, the rail follower device 100 is a lower side (Z2 side) of the traveling rail 20 and the trolley mechanism 30 located on the other side (X2 side) of the two traveling rails 20 in the transverse direction (X direction). And is fixedly attached to the trolley mechanism 30. FIG. 10 is a view showing the configuration of the rail follower 100 provided in the slide rail type overhead crane device 10A shown in FIG. 1 and a view from the front of the slide rail type overhead crane device 10A. As shown in FIG. 10, the rail follower device 100 adopts a configuration similar to the rail drive device 80 shown in FIGS. 6 and 8, but does not include a drive motor. Therefore, in the rail follower device 100, the four driven wheel portions 103 to 106 are rotatably supported by the pair of support frames 101 and 102. As a result, on the other side (X2 side) of the slide rail 70 in the longitudinal direction (X direction), sliding of the slide rail 70 can be well guided.

  As shown in FIG. 2, when the slide rail 70 moves to one side (X1 side), the rail follower device 100 does not support the slide rail 70. In this case, the slide rail 70 is connected to the connecting beam It is possible to move to the rail drive 80 located at the middle of 60. However, the slide rail 70 can not move to one side (X1 side) beyond the rail drive device 80 located in the middle of the connection beam 60.

  Further, as shown in FIG. 10, the rail follower device 100 is also provided with side rollers 107. The side rollers 107 are rotatably attached to both ends of the support frames 101 and 102 in the extending direction. Thereby, the movement of the slide rail 70 is smoothly guided by the rail follower 100. In FIGS. 1 and 2, the slide rail 70 slides only on one side (X1 direction) in the transverse direction (X direction). However, the slide rail 70 is slid on the other side in the transverse direction (X direction). When it is desired to slide in the (X2 direction), the rail driving device 80 is disposed instead of the rail following device 100. In that case, it is preferable to arrange the plurality of rail drive devices 80 and the anti-spring mechanism 90 in accordance with the slide amount also in the connection beam 60.

<About electric hoist>
Next, the electric hoist 110 will be described. FIG. 11 is a view showing the configuration of the electric hoist body 110 provided in the slide rail type overhead crane device 10A shown in FIG. 1 and a view from the side of the slide rail type overhead crane device 10A. FIG. 12 is a plan view showing the configuration of the electric hoist 110 shown in FIG. As shown in FIGS. 11 and 12, the electric hoist 110 mainly includes a hoist body 111, a mounting frame 120, and a hoist travel device 130. The hoisting machine main body 111 includes a hoisting motor 112, and the hoisting motor 112 rotates and drives a load sheave (not shown) to enable hoisting and lowering of the chain. A chain (not shown) hangs down from below the hoisting machine main body 111, but a hook 113 is attached to the lower end side of the chain. Then, when the hook 113 is loaded, the load can be lifted or the lifted load can be unloaded by driving the hoist motor 112.

  The chain located between the hoist main body 111 and the hook 113 is covered with an expandable cover 114 such as a bellows. Thus, even if the chain is pulled down, it is possible to prevent dust such as metal dust from the chain and splashes of machine oil from being scattered toward the outside. Further, a chain bucket 115 for storing the wound-up chain is also provided on the lower side than the winding machine main body 111, and it is possible to store the wound-up chain.

  Such a hoist main body 111 is attached to the mounting frame body 120. The mounting frame body 120 includes a pair of connecting bars 121 and 122, a pair of side frames 123 and 124, and a pair of connecting members 125 and 126. The pair of connecting bars 121 and 122 are rod-like members along the extension direction (Y direction) of the traveling rail 20, and are fixed to the pair of support frames 135 and 136 of the pair of hoist traveling devices 130, respectively.

  In addition, as shown in FIG. 1, the connection bar 121 is arrange | positioned at one side (X1 side) of the transverse direction (X direction) of the attachment frame body 120. As shown in FIG. Further, the connecting bar 122 is disposed on the other side (X2 side) in the transverse direction (X direction) of the mounting frame body 120 and is spaced apart from the connecting bar 121 by a predetermined distance. Thus, the chain and the hook 113 and the chain bucket 115 can be suspended from the hoisting machine main body 111 between the pair of connection bars 121 and 122. However, as shown in FIG. 12, the pair of connecting bars 121 and 122 are disposed at an interval that can receive the hoisting machine main body 111 including the hoisting motor 112 from the lower side.

  The pair of side frames 123 and 124 are connected to the connection bars 121 and 122 described above, and are arranged along the extending direction (X direction) of the slide rail 70. As shown in FIG. 11 and FIG. 12, the hoist main body 111 is attached between the side frames 123 and 124. Further, the pair of side frames 123 and 124 are connected by a pair of connecting members 125 and 126. The pair of connecting members 125 and 126 are provided with, for example, a rod screw and a nut, and the distance between the pair of side frames 123 and 124 can be adjusted.

  In addition, a hanging frame 127 is attached to the upper side (Z1 side) of the pair of side frames 123 and 124. The hanging frame 127 supports the hoisting machine main body 111 in a suspended state.

  Such a mounting frame body 120 is supported by the hoist travel device 130. The hoist travel device 130 includes four wheel sets 131 to 134, and each wheel set 131 to 134 includes a pair of support frames 135 and 136, and the pair of support frames 135 and 136 includes four wheels. The portions 137 to 140 are rotatably supported. In addition, the connection bars 121 and 122 described above are also supported by the pair of support frames 135 and 136 so that the mounting frame body 120 is instructed by the hoist travel device 130.

  In the configuration shown in FIG. 12, two of the four wheel sets 131 to 134 are drive wheel sets 131 and 134 to which the drive motor 141 is attached. In this drive wheel set 131, 134, for example, the drive motor 141 drives the two wheel portions 137, 138 aligned in the transverse direction (X direction) in the same manner as the rail drive device 80 shown in FIGS. Power is transmitted. However, the driving force may be transmitted by other methods. The remaining two of the four drive wheel sets 131 to 134 are driven wheel sets 132 and 133 in which the drive motor 141 is not present, but all of them are drive wheel sets and the drive force is dispersed and You can also

  As described above, when the hoist travel device 130 applies a driving force, the electric hoist 110 can slide along the slide rail 70.

  By the way, as shown in FIG. 11, in the electric hoist body 110, the hoist main body 111 is disposed between the pair of slide rails 70. The hoisting machine main body 111 is arranged above the lower flange 72 of the slide rail 70. With this configuration, it is possible to effectively use the space between the pair of slide rails 70. Further, as compared with the case where the hoist main body 111 is located lower than the lower flange 72, it is possible to prevent the hook 113 etc. from being located lower when the chain is stored, and the slide rail type overhead crane device 10A The dimension in the height direction of can be reduced.

  In the slide rail type overhead crane device 10A configured as described above, by operating the trolley mechanism 30, the slide rail 70 can be moved to a desired position in the extending direction (Y direction) of the traveling rail 20. Then, after moving the slide rail 70 or along with the movement of the slide rail 70, the electric hoist 110 can be operated with the load suspended by the hook 113. Thereby, it becomes possible to travel by the trolley mechanism 30 in the extending direction (Y direction) of the traveling rail 20 in a state in which the load is lifted, unloaded, or hung at a desired position.

  Further, by driving the rail drive device 80, the slide rail 70 can be moved along the extension direction (X direction) of the slide rail 70. Therefore, for example, as shown in FIG. 1 and FIG. 2, one side (X1) in the transverse direction (X direction) of the traveling rail 20 positioned on one end side (X1 side) of the connecting beam 60 in the extending direction (X direction). The slide rail 70 can be greatly protruded on the side). Then, the electric hoist 110 can be moved to the position where it is protruded, and the load can be lifted up or down.

<About the effect>
According to the slide rail type overhead crane device 10A configured as described above, the following effects can be produced. That is, the slide rail type overhead crane device 10A is attached to the upper attachment site and extends in the direction intersecting with the slide rail 70 and has a plurality of (for example, two) lower flanges 22 (first travel parts) The traveling rail 20 is provided. In addition, the slide rail type overhead crane device 10A includes an inner drive wheel 40, an outer drive wheel 50 (drive wheel), and a drive motor 36, and transmits a driving force from the drive motor 36 to lower flanges of the plurality of traveling rails 20. A plurality of trolley mechanisms 30 are provided on which an inner drive wheel 40 and an outer drive wheel 50 (drive wheel) travel along 22 (first travel unit).

  In addition, the slide rail type overhead crane device 10A includes a rail drive device 80 (rail transfer mechanism), and the rail drive device 80 (rail transfer mechanism) is at least attached to the trolley mechanism 30 and transfers the slide rail 70. Drive wheels 84c and 85c (wheels) are provided. In addition, the slide rail type overhead crane device 10A includes an electric hoist 110 that can move along the slide rail 70 and lift a load. Furthermore, the slide rail type overhead crane device 10A includes a bouncing mechanism 42. The bouncing mechanism 42 has an inner drive wheel 40 and an outer drive wheel 50 (drive wheel) with the lower flange 22 (first travel portion) interposed therebetween. And an anti-collision roller 45 traveling along the lower flange 22 (first travel portion) in cooperation with the inner drive wheel 40 and the outer drive wheel 50 (drive wheel). .

  According to such a configuration, by providing the rail drive device 80, it is possible to secure a sufficient slide amount of the slide rail 70.

Further, for example, when the electric hoist 110 is present on one end side (X1 side) of the slide rail 70 in the extending direction (X direction) in FIG. 2 and the load is lifted, the other end of the slide rail 70 The part side (X2 side) lifts the connecting beam 60, and thereby the other end side (X2 side) of the connecting beam 60 also lifts the trolley mechanism 30, the other side (X2 side) of the trolley mechanism 30 In this case, the inner drive wheel 40 may be lifted (separate) from the lower surface of the lower flange 22, which causes the loss of driving force or the resistance to driving. However, the slide rail type overhead crane device 10A of the present embodiment cooperates with the inner drive wheel 40 and the outer drive wheel 50 (drive wheel) to extend along the lower flange 22 (first travel portion) of the travel rail 20. A bounce mechanism 42 is provided with a running bounce roller 45. As a result, even if the inner drive wheel 40 and the outer drive wheel 50 (drive wheel) of the trolley mechanism 30 are lifted from the lower flange 22 (first travel portion) of the lower flange 22 and are idle, they are inclined or unable to travel Can travel without becoming As a result, the work area of the crane can be greatly expanded, and the operability can be greatly improved.
Can be prevented.

  Further, in the present embodiment, an inner large diameter gear 41 and an inner meshing gear 43 (driving force transmission mechanism) for providing a driving force to rotate the bounce prevention roller 45 are provided between the drive motor 36 and the bounce prevention roller 45. The bouncing roller 45 is driven by the drive of the drive motor 36. Therefore, it is not necessary to use a dedicated motor to drive the bounce roller 45, and it is possible to prevent an increase in the number of parts. In particular, it is possible to prevent an increase in running resistance, prevent an increase in the total weight, and drive a spring force that resists the lifting force, as compared with the one provided with a counterweight for preventing the lifting. It is possible to prevent an increase in running resistance more than a configuration in which the power is biased, thereby also preventing an increase in power consumption.

  Further, in the present embodiment, the bounce roller 45 can be provided with the same diameter as the inner drive wheel 40 and the outer drive wheel 50 (drive wheel). When configured in this manner, the parts of the inner drive wheel 40 and the outer drive wheel 50 and the bounce roller 45 can be made common, and an increase in the number of parts can be prevented. In addition, when the inner drive wheel 40 and the outer drive wheel 50 are lifted (separated) from the upper surface of the lower flange 22 and the bounce roller 45 contacts the lower surface of the lower flange 22, the lower flange 22 repels at the same speed. The roller 45 can be rotated. Thereby, it becomes possible to prevent the transport speed from being different between the trolley mechanism 30 on the other side (X2 side) in the transverse direction (X direction) and the trolley mechanism 30 on one side (X1 side), It is possible to prevent skewing and immobility without requiring a complicated mechanism.

  Further, in the present embodiment, the slide rail 70 is provided with an upper flange 71 (second travel unit) on which the drive wheels 84c and 85c (wheels) can travel. At the same time, at least one rail drive device 80 (rail transport mechanism) is provided opposite to the bounce mechanism 90 (second bounce mechanism), and the bounce mechanism 90 (second bounce mechanism) is rotatable. Is provided with a second anti-reflection roller 95 (second anti-reflection roller). In addition, the bouncing roller 95 (the second bouncing roller) is opposite to the drive wheels 84c and 85c (the wheels) of the rail drive device 80 (the rail conveyance mechanism) with the upper flange 71 (the second traveling portion) interposed therebetween. Deploy.

  When configured in this manner, the upper flange 71 is sandwiched by the bouncing roller 95 (second bouncing roller) and the drive wheels 84 c and 85 c (wheels). Thus, for example, in FIG. 2, the electric hoist 110 is present on the tip end side (X1 side) of the slide rail 70, and the load is suspended, and the other end side (X2 side) of the slide rail 70 is lifted. Even if it rotates, the anti-spring roller 95 can be in contact with the upper surface of the upper flange 71. This makes it possible to prevent the upper portion of the upper flange 71 from coming into contact with the connection beam 60, and to prevent running resistance in the slide of the slide rail 70.

  Further, in the present embodiment, the connection beam 60 is disposed between the plurality of traveling rails 20 and on the upper side (Z1 side) of the slide rail 70, and one end side (X1 side) of the connection beam 60. And the other end side (X2 side), the trolley mechanism 30 is rigidly connected.

  In such a configuration, it is possible to rigidly maintain the connection beam 60 between the two trolley mechanisms 30, so that positional deviation between the trolley mechanisms 30 can be prevented, and the trolley drive mechanism 35 and the rail drive can be prevented. An increase in traveling resistance of the device 80 can be prevented. In addition, the wear of the side rollers 33a, 34a, 89, 107 can be reduced, and the slide rail 70 can be smoothly slid.

  Further, in the present embodiment, the slide rail 70 is provided with the lower flange 72 located on the lower side (Z2 side), and the lower flange 72 is provided with a driving force for moving the electric hoist body 110. A hoist travel device 130 is movably supported. In addition, the hoist travel device 130 is connected to the mounting frame body 120 supporting the electric hoist body 110, and the electric hoist body 110 is mounted at a position above the lower flange 72 (Z1 side). It is attached to the body 120.

  In such a configuration, as shown in FIG. 3 and FIG. 11, the electric hoist 110 can be disposed in the dead space between the adjacent slide rails 70. Thus, the space in the height direction (Z direction) of the slide rail type overhead crane device 10A can be prevented from increasing. Thus, for example, even if the slide rail type overhead crane device 10A is installed in the clean room, the increase in the clean room ceiling height can be suppressed, and the effect of significantly reducing the clean room construction cost and the air cleaning apparatus cost can be achieved. Have.

That is, at portions positioned on both end sides of the three traveling rails 20, rail driving devices 80 having the same configuration as the rail driving devices 80 shown in FIG. 6 are provided. Therefore, the description of the details of the configuration is omitted. In the following description, it is assumed that rail drive devices 80 located at both ends of the three travel rails 20 are rail drive devices 80B1 and 80B2.

  Further, a rail drive device 80 (hereinafter, referred to as a rail drive device 80B3) disposed at a position where the middle travel rail 20 is located among the three travel rails 20 is the same as the rail drive devices 80B1 and 80B2 described above.

Specifically, the bounce mechanism 160 mainly includes a pair of holding plates 162 and 163, a support shaft 164, and a bounce roller 166. The pair of holding plates 162 and 163 is disposed on the upper side of the upper flange 71. The upper flange 71 corresponds to the second travel unit.

  Further, a support shaft 164 is attached to the pair of holding plates 162 and 163. A bounce roller 166 is rotatably attached to the support shaft 164 via a bearing 165. The bounce roller 166 corresponds to a second bounce roller. Similar to the bounce mechanism 90, the bounce roller 166 protrudes below the lower flange 62 of the connection beam 60 B (Z 2 side) and abuts on the upper flange 71 of the slide rail 70.

  The bounce prevention mechanism 160 suppresses the floating of the drive wheel portions 84 and 85 (the separation of the slide rail 70 from the drive wheel portions 84 and 85) due to the rotation of the slide rail 70. The bounce prevention roller 95 may be disposed so as to have a slight gap without contacting the upper flange 71.

  Next, in the present embodiment, the rail follower device 100 is provided between the rail drive device 80B1 and the rail drive device 80B3, and is provided between the rail drive device 80B3 and the rail drive device 80B2. Hereinafter, the rail follower 100 of the present embodiment is referred to as a rail follower 100B. FIG. 20 is a view showing a configuration of the rail follower 100 provided in the slide rail type overhead crane device 10B and a view from the front of the slide rail type overhead crane device 10B. FIG. 21 is a plan view showing the configuration of the rail follower 100 shown in FIG.

  As shown in FIGS. 20 and 21, the rail follower 100B includes a pair of support frames 101B and 102B. Among these, in the support frame 101B, the two driven wheel portions 103 and 104 are arranged in the transverse direction (X direction) in a state where they can freely rotate. Further, also in the support frame 102B, the two driven wheel portions 105 and 106 are arranged in the transverse direction (X direction) in a state where they can freely rotate.

  Here, the support frame 101B and the support frame 102B are connected by a connecting frame 108B. Thus, the support frame 101B, the support frame 102B, and the connection frame 108B are formed in the shape of a carriage, and the driven wheel portions 103B to 106B that rotate in a driven manner are attached to the outside of the carriage. The driven wheel portions 103B to 106B travel on the upper surface of the upper flange 71 of the two slide rails 70, but the flanges of the driven wheel portions 103B to 106B are out of the inner edge of the upper surface of the upper flange 71. Thus, removal of the driven wheels 103B to 106B is prevented.

  The rail follower device 100B is also provided with a side roller 107B, and the side roller 107B is provided rotatably with respect to the inner surface of the upper surface of the upper flange 71. The side wheels 107B also prevent the driven wheel portions 103B to 106B from being disengaged.

<About the effect>
The slide rail type overhead crane device 10B described above can also produce the same effect as the slide rail type overhead crane device 10A according to the first embodiment.

  Moreover, in the slide rail type overhead crane apparatus 10B which concerns on this Embodiment, in the extending direction (Y direction) of the traveling rail 20, only one connection beam 60B is arrange | positioned. Thus, on the upper side (Z1 side) of the two slide rails 70, it is not necessary to adopt a configuration in which the connection beams 60B are closely opposed to each other, and a space can be provided on the upper side (Z1 side) of the slide rails 70. . Thereby, it is possible to easily arrange, for example, the bouncing mechanism 160 and the like.

In the environment where iron powder is not favored, hard urethane wheels or stainless steel wheels or resin rollers are preferable as the wheels and side rollers, and it is preferable to lay stainless steel plates on the rail treads in combination. Further, although the driving force of the bouncing mechanism 42 is obtained through the trolley driving mechanism, the bouncing mechanism 42 may be provided with a dedicated drive motor.

  In each of the above-described embodiments, the rail drive devices 80 and 80B1 to 80B3 and the rail follower devices 100 and 100B correspond to the rail transport mechanism. However, the rail transport mechanism may use other than these. As another configuration, it is possible to use rollers, rollers, belts and the like other than illustrated. In each of the above-described embodiments, the bouncing mechanism 42 corresponds to the bouncing mechanism, and the bouncing mechanism 90 and the bouncing mechanism 160 correspond to the second bounce mechanism. Further, the bounce prevention roller 45 corresponds to the bounce prevention roller, and the bounce prevention roller 95 and the bounce prevention roller 166 correspond to the second bounce prevention roller. However, rollers or rollers other than these correspond to the anti-spring roller and the second anti-spring roller, and the configuration provided with the above-described rollers and rollers is equivalent to the anti-spring mechanism or the second anti-spring mechanism. Also good. In addition, a drive motor may be provided to drive the bouncing rollers 95 and 166 of the second bouncing mechanism.
