In a suspension lifting device in which a suspension belt is wound around a pulley attached to a drive shaft so that it can be unwound, there is a recessed space opened to the side inside the belt winding body of the pulley. At the same time, the inner end of the hanging belt is fixed to the boss part located in the center of this same large space and integrated with the body part, and the belt attachment allows the members to be fitted in relative rotation and insertion/removal. Then, the hanging bell (extending from the belt attachment part f'j) is led out to the outside of the body through a slit with one end open provided in the body, and the body is connected to the bell. I. Suspension formed by forming a protruding cam part on the inner circumferential surface of the body part to sandwich the hanging belt between the tip circumferential surface of A and the belt attachment part when rotated in the winding direction. We propose a lifting device.

とか出来る。When loading and unloading the conveyed objects onto the hanger 16, the electromagnetic brake I9 is switched from the braking state to the releasing state, and at the same time, the electricity is supplied from the power supply rail 7 to the current collecting unit 1-8. The direct drive motor 13 is energized to drive its outer rotor 20 in normal rotation, and the rotation is transferred to each of the spur gears 21 to 23 and the drive shafts 17 and 18.
The transmission is transmitted to each pulley 15a to 15c via the suspension bell I□ 1.4 a
~I By interlockingly rotating the 4C in the feeding direction at the same speed, the hanger 16 can be lowered to an arbitrary level. Further, the outer rotor 20 of the motor 13
The hanger 16 can be raised by rotating the pulleys 15a and -15C in the opposite direction and rotating the pulleys 15a and -15C at the same speed in the direction of winding up the hanging belts 14a to +4c.

When winding +4c, as explained earlier, the inner end 29 of the hanging belt l4a-14c is fixed to the belt attachment member 32, and this belt attachment member 32 is attached with the flange 26 removed. The belt is fitted to the boss portions 28 of the pulleys 15a to 15c and inserted into the recessed space 27, and the belt is attached to the hanging bells 1 to 14 extending from the member 32.
a to 14c, the belt is attached to the tip peripheral surface 32a of the member 32.
The suspension belt 1, 4. a
~14c sandwiched between the slits 33 or 34
The belt is led out from the belt winding trunk 24. Then, the hanging belts 14a to 14c are wound around the body 24 in a direction opposite to the winding rotation direction of the pulleys 15a to 15c. Finally, by screwing the flange 26 to the side of the body 24, the work of winding the suspension belt is completed.

。Since the pulleys 1.5b and 15c are attached to both ends of the drive shaft 18 so as to be on the outside of the flange 26, the hanging belt 14C is wound around one of the pulleys 15c as shown in FIG. When wrapping the hanging belt 4b on the other pulley 15b, the belt is attached by turning the member 32 over and fitting it into the boss part 28, and then attaching the hanging belt l- to the other pulley 15b.
14b is led out from the slit 34 to the outside of the body 24. Therefore, in this pulley 1.5b, the hanging belt 141) is sandwiched between the distal end circumferential surface 32a of the member 32 and the protruding cam portion 36 when the belt is attached.

たって安全に使用することか出来る。Moreover, although the belt installation is done by simply fitting the part H into the boss part of the pulley as described above, when the pulley rotates in the direction of belt winding -1-, the surface belt installation does not work. Since the hanging belt is sandwiched between the tip peripheral surface and the protruding cam part on the bully side, when attaching the hanging belt, the tensile force acting on the belt is applied to the set screw part that fixes the hanging belt to the member. Almost no action is required, therefore, the risk of breakage from the threaded hole at the inner end of the belt is greatly reduced, and the belt can be used safely for a long period of time.
