部上に据え付けている。The elevating drive unit 22 has an output shaft 3 of a reducer 31 directly connected to a motor 30 as shown in FIGS. 3 and 4.
2 is supported on the base 33 by a pair of left and right bearings 34 and 35, and the base 33 serves as a rotation preventing coupling means for preventing the motor 30 and the reducer 31 from rotating around the output shaft 32. A connecting pin 37 connects the bracket 36 attached above and the case projecting portion 31a of the reducer 31.
The driving gear wheels 23 and 24 are connected to the output shaft 32 at an intermediate position between the two bearings 34 and 35, and are mounted on the front end of the lower frame 1 via the base 33. It is installed.

。In addition, when raising and lowering the lifting carriage 6 in order to make the load transfer means 7 correspond to an arbitrary height of the shelf, the motor 30 of the lifting drive unit 22 is operated, and its rotation is controlled by the speed reducer 31.
The pair of elevating drive chains 16.1
All you have to do is turn 7. That is, when raising the lifting carriage 6, the drive gears 23 and 24 are rotated in the normal direction to rotate the chains 16 and 17 in the direction of lifting the lifting carriage 6. At this time, the chain 16 is ．．
Counterweight 29 suspended by 17
descends due to gravity. When the elevating carriage 6 is lowered, the driving gears 23 and 24 are reversed and the chains 16 and 17 are rotated in a direction to lift the counterweight 29, so that the elevating carriage 6 is lowered by gravity.

Therefore, the coupling pin 37 is configured to be sheared when an overload of a certain level or more is applied to the elevating carriage 6 side, and the movement of the reducer 31 that rotates within a certain range around the output shaft 32 is limited. If it is configured to be detected by a switch or the like, the coupling pin 37 can also be used as a torque limiter.

Therefore, the diameters of the drive gears 23, 24 must be considered so that the chains 16, 17 do not come into contact with the motor 30. However, as shown in FIG.
It is also possible to provide guide gear wheels 39a and 39b for each chain 16 and 1f to widen the gap between the chains 16 and 17 that make a U-turn on the upper side of the chain. The guide gear wheels 39a, 39b can be pivotally supported by a bracket 40 connected to a bearing 34.degree. 35 protruding from the base 33.

組み立て作業も簡単容易に行える。(Operations and Effects of the Invention) As described above, according to the crane elevating carriage drive device of the present invention, the elevating carriage and the counterweight are suspended from both ends of the elevating drive chain, and the power required for elevating and lowering the elevating carriage is reduced. Although this is aimed at reducing the weight, since the lifting drive unit that rotates the lifting drive chain is installed on the lower frame, maintenance and inspection of the lifting drive unit is easy, and the center of gravity of the entire crane is lowered, improving stability. improves. Moreover, the elevating drive unit supports the output shaft of the motor with a speed reducer on a base via a pair of bearings, and connects the base and the motor with a speed reducer by a rotation-preventing coupling means. Since the drive gear is attached to the output shaft at an intermediate position of the bearing, the structure of the entire elevating drive unit is extremely simple, and it is only necessary to attach the base to the lower frame. Coupled with the fact that the lifting drive unit is installed on the lower frame, assembly of the entire crane can be easily performed.
