The auxiliary shuttle drive unit 73 may be installed at an intermediate portion of the support member 70. When the support member 70 is long, the auxiliary shuttle drive unit 73 may be installed at a predetermined position.

The pair of running rails 10 are generally spaced apart from the floor by posts extending downward from the floor or supports extending downward from the ceiling. As described above, a pair of the running rails 10 are installed at positions facing each other by a predetermined distance, and a pair of saddle portions 20 are provided on each of the running rails.

The saddle portion 20 moves along the running rail 10 in the longitudinal direction of the running rail. The movement of the saddle portion 20 is performed by operating the saddle driving portion 21 provided at both ends. That is, the saddle portion 20 travels along the longitudinal direction of the running rail 10 by the saddle driving portion 21 at both ends of the saddle portion 20. [ The shuttle drive unit 30 is fixedly connected to the saddle unit 20 at a lower side of the saddle unit 20 and the main and shuttle girders 40 are movable with respect to the shuttle drive unit 30 The main and shuttle girders 40 move transversely with respect to the running rail 10 and the saddle portion 20 due to the operation of the shuttle driving portion 30. [

At this time, the own weight of the main and shuttle girders and the weight of the conveyed articles carried by the clippers cause an offset load, The saddle portion 20 and the saddle drive portion 21 are lifted from the running surface of the running rail 10 in conjunction with the main and shuttle girder on the opposite side of the crane. The first operating wheel 23 of the saddle drive unit 21 is lifted from the running surface (contact surface) of the running rail 10 and the running rail 23 of the saddle driving unit 21 is lifted from the running rail The frictional force is reduced, and the first operating wheel 23 is slipped on the running rail 10. [ This makes it difficult for the saddle portion 20 to move smoothly in the longitudinal direction along the running rail. At this time, the first counter roller 25 (the counter roller) is in intimate contact with the traveling rail 10, It is possible to prevent the first operating wheel 23 from being lifted from the running surface of the running rail. The first counter roller 25 may also be referred to as a traveling counter roller since the saddle portion 20 serves to smoothly travel in the longitudinal direction along the traveling rail without hoisting the traveling rail.

The shuttle drive unit 30 is a device for moving the main and shuttle girders 40 in the lateral direction with respect to the running rail 10 and includes a drive motor 31 for driving the shuttle drive unit 30, And a third operating wheel 32 which is operated by the drive motor to move the main and shuttle girders 40 in the lateral direction of the running rail 10, And is adjacent to the upper inner surface of the girder 40.

The clube driving unit 50 includes a driving motor 51 for driving the climb driving unit and a driving motor connected to the driving motor. The climb driving unit 50 is operated by the driving motor to rotate the climb 60 in the longitudinal direction of the main and shuttle girder 40 And the fourth operating wheel 52 is adjacent to the lower inner surface of the main and shuttle girder 40. The fourth operating wheel 52 is disposed on the lower inner surface of the main and shuttle girder 40,

The shuttle drive unit 30 of the present invention is fixed to the lower surface of the saddle portion 20 such that the main and shuttle girders 40 are movable relative to the shuttle drive unit 30, Is moved in the lateral direction of the running rail (10) with respect to the operating wheel (32).

On the opposite side of the third operating wheel 32, another operating wheel 32-1 is provided with a side surface (vertical plate) of the main and shuttle girder 40 interposed therebetween, (Not shown) of the saddle portion 20 is connected to the lower surface of the saddle portion 20 by a connecting member (not shown). Preferably, the other operating wheel 32-1 is a driven wheel, located at the same level as the third operating wheel 32, and adjacent to the upper inner surface of the main and shuttle girder 40. [ The main and shuttle girders 40 are moved by operating the drive motor 31 of the shuttle drive section and operating the third operation wheel 32 and the movement of the main and shuttle girders 40 causes the other operation wheel 32- 1) is rotated.

The other operating wheel 52-1 is further provided on the opposite side of the fourth operating wheel 52 with the side surface (vertical plate) of the main and shuttle girder 40 interposed therebetween, The operation wheel 52-1 of the crane 60 is connected to the crube 60 by a connecting member (not shown). Preferably, the other operating wheel 52-1 is located at the same level as the fourth operating wheel 52 and is adjacent to the lower inner surface of the main and shuttle girder 40, as a driven wheel. The driving motor 51 of the climb driving unit 50 is operated and the climb 60 connected to the climb driving unit by operating the fourth operating wheel 52 moves along the main and shuttle girder 40 together with the climb driving unit And the other operating wheel 52-1 is also rotated with respect to the main and shuttle girders 40 by the movement of the clutch 60. [

In the intermediate portion of the above-mentioned support member 70, a transverse connection bar 72 for connecting the support members to each other is formed, thereby maintaining the separation distance between the support members and reinforcing the rigidity. An auxiliary shuttle drive unit 73 is further provided below the support member. The auxiliary shuttle drive unit is connected to the drive motor 75 and the drive motor and is composed of operation wheels 76 and 76-1 adjacent to the inner surface on the upper side of the main and shuttle girder 40 and adjacent thereto. The operating wheels are constructed so as to face each other with the boundary of the side surface (vertical plate) of the girder 40 facing each other, in which two first operating wheels 76 on one side of the girder are juxtaposed with each other, The wheels 76-1 are also juxtaposed.

A part of the circumferential surface of the one operation wheel 76 is formed as a gear and connected to the rotation shaft of the drive motor 75 so that the one operation wheel 76 is rotated by the operation of the drive motor 75. The main and shuttle girders 40 move by the rotational force of the operating wheel 76 and the other operating wheel 76-1 which is the driven wheel also rotates by the movement of the girder. Operation of the operating wheel 76 by the drive motor 75 makes movement of the main and shuttle girder 40 more convenient. The operation wheels 76 and 76-1 of the auxiliary shuttle drive unit 73 can move the main and shuttle girders 40 out of the shuttle drive unit 30 on one side of the crane device for transporting the deliveries, When the operation is completed and then re-entered into the shuttle drive unit 30, the main and shuttle girders 40 are securely moved and reentrant. In addition, by preventing or compensating for the deflection of the girder, it is ensured that the girder is reliably re-entered into the escaped shuttle drive. That is, the auxiliary shuttle drive unit 73 installed on the support member 70 allows the girder to move easily, and also functions to maintain the height and the horizontal state of the girder incidentally.

The auxiliary shuttle drive unit 73 of this function is constituted in a slide rail type ceiling crane apparatus constituted by the support member 70 and constitutes an operation roller (not shown) in any device installed in the support member, May be configured to be adjacent to the inner surface on the upper side of the main and shuttle girder (40).

That is, the auxiliary shuttle drive unit 73 makes the movement of the main and shuttle girders 40 convenient, and at the same time, when the shuttle drive unit 30 is re-entered after transporting the transported goods, 32 on the upper surface of the operating wheel 32 without any collision. For this function, it is preferable that the third operating wheel 32 of the shuttle driving unit 30 and the operating wheels 76 and 76-1 of the auxiliary shuttle driving unit 73 are positioned at the same level.

Since the main shuttle girder 40 is generally long in order to prevent the movement of the girder after it has escaped from the shuttle drive unit 30, In order to ensure a smooth movement of the girder 40 and additionally to prevent the main and shuttle girder 40 from sagging due to its own weight when it exits the shuttle drive 30. The auxiliary shuttle drive unit 73 is generally connected to the support member 70 and installed below the support member. At least one auxiliary shuttle drive unit 73 may be installed at a predetermined position in a slide rail type ceiling crane apparatus having the support member 70.

A second counter roller 74 is provided above the auxiliary shuttle drive unit 73. The second counter roller 74 also functions to prevent lifting of the main and shuttle girder 40. [

The second counter roller 74 is installed in a rectangular or square structure 71 inside the lower side of the support member 70. The second counter roller 74 is disposed on the upper side of the main and shuttle girder 40 By intimate contact, the main and shuttle girder 40 presses the main and shuttle girders above the main and shuttle girders when the main and shuttle girders 40 are moved transversely relative to the running rail 10, It prevents the girder from lifting due to the load. These counter rollers are called lateral counter rollers.

A girder leveler 80 is further provided at a predetermined position inside the support member 70. The girder leveler 80 is provided with two side plates 82 inside the support member 70 And operating wheels 81 and 81-1 are rotatably mounted on the side plates inside the respective side plates. Specifically, the operating wheels 81 and 81-1 are installed between the side plates 82 and the side surfaces of the main and shuttle girders 40, and the circumferential surfaces of the operating wheels 81 and 81-1 are connected to the main and shuttle And is adjacent to the upper inner surface of the girder 40. Further, a side plate support bar 83 is provided between the side plates 82 to connect the side plates. The girder leveler 80 having such a configuration is connected to the support member 70 by a connecting member such as a bolt. The support bar 83 maintains the distance between the girder leveler 80 and reinforces the rigidity.

The girder leveler 80 is installed between the running rail 10 and the auxiliary shuttle drive unit 73 as shown in the figure so that the main and shuttle girder 40, which exits the shuttle drive unit 30 for lateral movement, To prevent sagging downward.

Generally, when the main and shuttle girders 40 are long, the main and shuttle girders 40 are pulled downward due to their own weight when they move out of the shuttle drive 30 to transport the goods. This deflection prevents horizontal movement of the girder. Particularly, if the girder can not maintain the horizontal state at the time of moving, reentry to the shuttle driving portion is not desired or the reentry itself can not be performed. In order to compensate for this, a girder leveler 80 is additionally provided so that the operation wheels 81 and 81-1 of the girder leveler support the girder under the upper inner surface of the main and shuttle girder 40, To prevent sagging. It is preferable that the operating wheel 32 of the shuttle driving unit 30 and the operating wheels 81 and 81-1 of the girder leveler 80 are positioned at the same level in order to prevent sagging of the girder. The girder leveler 80 may be provided at one or a plurality of predetermined positions of the support member 70.
