[0002]

2. Description of the Related Art Conventionally, as a hoisting and conveying device having an auxiliary supporting device, a plurality of electric chains are attached to a traveling girder traveling along a fixed girder, as disclosed in Japanese Patent Laid-Open No. 57-85788. A device is known in which a trolley with a block is placed, two elevating girders are laterally arranged at a lower level than the fixed girder, and a plurality of trolleys with suspenders are placed on each elevating girder. Has been.

[0003]

In the case of the above-mentioned conventional hoisting and conveying apparatus, when the object to be conveyed is hoisted and supported by the trolley with the lifting tool placed on the two hoisting and lowering girders, the hoisting and lowering girder is mounted on the lower part of the hoisting and lowering girder. Since the large load of the transported object acts diagonally through the lifting device of the trolley with the lifting device, a large horizontal force acts on the lower part of the lifting girder, which strengthens the lifting girder and its lifting support device against the horizontal force. Therefore, there is a problem that the manufacturing cost of the hoisting and conveying device having the auxiliary supporting device is high.

According to the present invention, a hoisting machine 3 for hoisting an object to be transported is attached to a traveling frame 2 which travels in the front-rear direction, and at one side of a passage of a suspension bar 4 in the hoisting machine 3. A first elevating rail 5 extending in the front-rear direction is provided, and a second elevating rail 6 and a third elevating rail 7 extending in the front-rear direction are provided on the other side of the passage of the suspension member 4, and the first elevating rail 5 is provided. The support fitting 9 is fixed to the first trolley 8 placed on the second trolley 10 and the third trolley 10 and the third trolley 10 placed on the second lifting rail 6.
An auxiliary supporting traverse beam 14 equipped with a transported object suspending device 13 is attached to a support member 12 supported by a third trolley 11 mounted on the elevating rail 7 so as to be movable in the left and right directions. Further, since the support pin 15 is provided on one of the support fittings 9 and the pin insertion hole 16 is provided on the other side, a large load of the carried object is perpendicular to the beam longitudinal direction at the lower part of the transverse beam for auxiliary support. Since it does not act from an oblique direction and therefore it is not necessary to strengthen the lifting rail and its lifting support device or auxiliary support device against horizontal force, it can be manufactured at low cost, and the transverse beam 14 can be produced laterally. When advanced to
Since the tip portion of the transverse beam 14 is supported by the first trolley 8 via the support fitting 9 and the support pin 15, the transverse beam 14 can be strongly supported in a stable state against the load of the transported object 81. Further, by moving the traverse beam 14 backward in the lateral direction, the traveling frame 2 with the hoisting machine for hoisting the transported object 81 is freely moved in the front-rear direction through the side portion of the traverse beam 14. You can In addition, a receiving bracket 18 fixed to the end of the insertion display plate 17
Is attached to the first trolley 8 or the support fitting 9 by means of a pivot 19 extending in the front-rear direction, and a guide cylinder 20 fixed to the support fitting 9 is provided with a display plate pushing-up operation member 21 and a pressure receiving member 22 in the left-right direction. And a pressing member 24 for pressing the pressure receiving member 22 is fixed to the tip of the transverse beam 14 by interposing a moving spring 23 between the operating member 21 and the pressure receiving member 22. Thus, it is possible to easily confirm that the support pin 15 is fitted into the pin insertion hole 16 by looking at the insertion display plate 17.
