Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for supporting power supply cables or other cables.

The present invention relates to a trolley transport device that can transport a trolley across a material passage gap provided on a trolley running rail. In the case of shelving equipment in which goods are carried in and out of multi-tiered shelves using electric shelving IJ lifts, a trolley running rail is constructed along the upper part of the lift running path, and a large number of trolleys run along the rail. By trolley
A power supply cable for the shelf stack is suspended and supported. On the other hand, if a shutter is provided at the end of the shelving equipment in the direction of lift travel for the purpose of preventing flames or theft, or if an elevating smoke-proof hanging wall is installed, the rails are divided and the rail passes through the shutter or smoke-proof hanging wall. It is necessary to provide a relatively large gap for this purpose.

The lever 34 is held in the collapsed position by the elasticity of the lever 34. Therefore, when the transport/operating trolley 27 is moved forward by the shelf stacking lift 29 in this state, the locking/operating portion 26 of the trolley 27 is held in the forward position of the lever 34. The railed trolley 14 is engaged with the engaging portion 41 and moved forward via the lever 34 . When the railed trolley 14 is further moved forward after the guide slope 39 of the lever 34 engages with the guide member 36, the lever 34 is rotated clockwise by the guide member 36 via the guide slope 39. When the center line of the tension spring 43 slightly exceeds the center line of the pivot 35, the lever 34 is rapidly rotated clockwise due to the tension force of the tension spring 43, and the front part of the trolley with rails 14 is rotated. When the trolley 6 hits the stopper 33 and the front end surface of the lower auxiliary rail 3 contacts or approaches the rear end surface of the lower main rail 8, the retreat prevention engagement portion 40 of the lever 34 prevents the holding frame 37 from retreating. Since it is engaged with the prevention stopper 38, the lower auxiliary rail 3 is prevented from moving backward.

As described above, when the front end surface of the lower auxiliary rail 3 is supporting or close to the rear end surface of the lower main rail 8, the lever 34 and the backing prevention stopper 38 prevent the lower auxiliary rail 3 and the lower main rail 8 from being connected. Relative separation movement is prevented, and since the forward engagement portion 41 of the lever 34 is disengaged from the locking/operating member 26 of the transfer operation trolley 27, the transfer/operation trolley is moved by the shelf IJ lift 29. 27 can be moved forward from the lower auxiliary rail 3 along the lower main rail 8, and a power supply and electrical control cable 45 is attached by a cable hanger 11 across each of the upper trolleys 10, 10' and each lower trolley 9. It is being

The transport and operation trolley 27 and each of the lower trolleys 9 adjacent to each other in the longitudinal direction are connected via a sacrificial condition (not shown) such as a chain or wire rope, and when the shelving IJ lift 29 is moved forward, Each lower trolley 9 is moved forward from the lower auxiliary rail 3 along the lower main rail 8 via the trolley 27 and the flexible strip. Next, when the shelf stacking lift 29 is moved backward, the transfer/operation trolley 27 is moved backward, and each of the lower trolleys 9 is sequentially moved backward by the trolley 27. When the member 26 engages with the lever-folding operation portion 42 of the lever 34 and then moves backward, the lever 34 is rotated counterclockwise, that is, in the direction of the folding, and the center line of the tension spring 43 slightly crosses the center line of the pivot shaft 35. , the lever 34 is rapidly rotated counterclockwise by the tensile force of the tension spring 43, and the back-back prevention engaging portion 4 of the lever 34 is rotated counterclockwise.
0 is removed from the back-up prevention stopper 38, and then the transfer/operation trolley 27 engages with the back-restriction stopper 28 fixed to the front part of the lower auxiliary rail 3. The trolley with rails 14 can be moved backwards via the rails 27.

．． One end of a cable support member 47 is pivoted to the lower part of the support fitting 46 fixed to the rear end of the lower auxiliary rail 3 by a pivot shaft 48 extending in the front-rear direction. The middle part of the cable support member 4 is pivotally connected to a support shaft 50 extending in the left-right direction, and the cable support member 4 is attached to a hook 51 provided at the tip of the support lever 49.
The other end of the support lever 49 is locked, and a holding tension spring 52 is attached that extends around the support lever 49 and the support fitting 46 and passes near the supporting rod 50.
3 is arranged below the distance G, and when the operating portion 53 is pressed down by a shutter or the like and the support lever 49 is rotated clockwise, the hook 51 of the support lever 49 is detached from the cable support member 47. Therefore, the cable support member 47
pivots downwards about the pivot 48, so that the cable 45 falls from the cable support village 47. The support fitting 46 also serves as a stopper to prevent the rearmost lower trolley 9 from coming off the rear end of the lower auxiliary rail 3.

When carrying out this invention, flanged wheels are employed as the running wheels 4 of each of the main trolleys 6 and 7 and the running wheels of each of the other trolleys, and the guides for these trolleys are provided.

The character may be omitted. According to this invention, the trolley with rail 14 that runs across the upper main rail 1 and the upper auxiliary rail 2 arranged in series in front of the upper main rail 1 with the member passing gap G interposed therebetween is connected to the lower auxiliary rail 3 and both front and rear sides thereof. The main trolleys 6 and 7 are fixed to the main trolleys 6 and 7, and each of the main trolleys 6 and 7 is equipped with a plurality of running wheels 4 arranged at an interval D in the longitudinal direction that is larger than the gap G. Even if there is a relatively large gap G between the upper main rail 1 and the upper auxiliary rail 2 for passing members such as shutters and smoke-proof hanging walls, it is possible to hold a large number of lower trolleys 9 for supporting cables. The trolley with rails 14 can be run smoothly, and the trolley with rails 14 can be moved forward to bring the front end surface of the lower auxiliary rail 3 close to or close to the rear end surface of the lower main rail 8. , many lower parts.
