Abstract

PURPOSE:To allow a crane to be continuously changed in direction by resting one of running wheels which are provided for the both side of the beam of an over head crane, onto a turn table, resting the other wheel onto a turn trolley, and thereby turning the turn trolley to the different direction between No.1 and No.2 linear paths. CONSTITUTION:Running wheels 6A and 6B on one side of the beam of an over head crane 1 are rested on the turn rail 26 of a turn table 21, and running wheels 7A and 7B on the other side are rested on the turn rail 33 of a turn trolley 30. The table 21 is rotated as fulcrum at a point A, and the turn trolley 30 is accordingly run along rails 29A and 29B in a circular arc shape by means of wheels 31A and 31B so that the over head crane 1 is rotated from No.1 linear path 2A to No.2 linear path 2B in the different direction. In this case, the turn rail 26 is connected with a rail 4B, and the rail 33 is connected with a rail 5B. This thereby permits the over head crane to be run to the direction of No.2 linear path 2B over the running rails 4B and 5B which are changed in direction.

This switching device 3 includes a turntable 21 and a swivel base i30.
For smoother rotation, turntable 2
1 and a swing truck 30 are connected by a swing beam 61 and integrated. That is, this swing beam 61 includes an inner support section 61a erected on the outer side of the turntable 21, an outer skin column section 61b erected on the outer side of the swing truck 30, and these inner and outer support sections 61a, 61b. m connected between the upper ends
With the beam part 61c, the turntable 21 and the turning trolley 3
It is formed in the shape of a gate surrounding the overhead crane 1 that has moved onto the crane 0. Further, an arcuate rail 62 that guides the rotating cart 30
is a single tree, and a swing drive device 63 is provided independently of the travel drive device 41B of the overhead crane 1. This swing drive device 63 is provided with a drive gear 65 on the output shaft of a faucet motor 64 with a speed reducer disposed on the swing truck 30, and this drive gear 65 is fixed to a swing wheel 67 via an intermediate gear 66. It is configured to be connected and interlocked with a driven gear 68.

According to the second practical example of the turning device 3, the turntable 21 and the turning cart 30 are connected and integrated by the gate-shaped turning beam 61, so that (1) the turntable 21 and the turning cart 30 are Since the overhead crane 1 is left behind and rotated, the load on the overhead crane 1 can be reduced.

(2) The turntable 21 and the rotating truck 30 can surely rotate in synchronization, and there is no danger of the overhead crane 1 falling.

(3) It is possible to reliably support the force that urges the turntable 21 and the rotating carriage 30 outward, which is generated by centrifugal force or the like when the rotation occurs.

(4) Due to vibrations such as earthquakes transmitted from the ground, the m relics may resonate and the shaking may be amplified. It can be connected to the structural member supporting 5B by passing the hook, and amplification of shaking can be prevented.

Effects of the Invention As described above, according to the present invention, one overhead crane can be run continuously on the first straight route and the second straight route that are connected in the bending direction. Compared to the case where one overhead crane was required for each straight path, transportation efficiency can be improved and equipment costs can be reduced by 6.

Furthermore, by providing this diversion device at each bend in the straight path, the travel path of the overhead crane can be arbitrarily arranged, and the factory space can be used effectively.
