[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] The utility model embodiment discloses an integrated casting elevator traction sheave.
[0026] The utility model provides Figure 1-3 The integrated cast elevator traction wheel shown includes a wheel body 1 and a driving worm wheel 2 fixedly arranged on the side wall of the wheel body 1. The wheel body 1 and the driving worm wheel 2 are integrally cast. The outer wall of the wheel body 1 is provided with a plurality of rope grooves arranged at intervals. The outer wall of the wheel body 1 is provided with an annular groove. Two symmetrically arranged rotating plates 3 are rotatably penetrated in the annular groove. The two rotating plates 3 are both arranged in an arc shape. The two rotating plates 3 are connected by a connecting mechanism. The connecting mechanism includes a connecting bolt 7. Through holes 12 are provided inside the two rotating plates 3 at one end close to each other. The connecting bolt 7 is threadedly arranged in the two through holes 12, and a limiting nut 14 is threadedly sleeved on the threaded end. A mounting plate 4 is fixedly arranged on the upper end of the outer wall of the rotating plate 3. The internal thread of the mounting plate 4 is penetrated with a mounting bolt 13.
[0027] A rotation groove is provided at the upper end of the side wall of the rotating plate 3, a cross bar 5 is fixedly provided in the rotation groove, a limit plate 6 is rotatably sleeved on the rod wall of the cross bar 5, and the limit plate 6 is matched with a plurality of rope grooves.
[0028] Before using the traction wheel, connect the wheel body 1 and the driving worm gear 2 to the reducer, then place the two rotating plates 3 in the annular groove and fix them by connecting bolts 7 and limit nuts 14, then install the mounting plate 4 inside the motor channel by mounting bolts 13, fix the position of the rotating plate 3, and then after the traction rope is put into the rope groove outside the wheel body 1, rotate the limit plate 6 and fix the position of the limit plate 6 so that the limit plate 6 covers and limits the traction rope, which can prevent the traction rope from slipping out of the rope groove as much as possible during the use of the traction wheel.
[0029] In order to fix the position of the limit plate 6 when the limit plate 6 is used horizontally, as shown in FIG. Figure 1-2As shown, a through hole is provided inside the end of the limit plate 6 close to the cross bar 5, and a support rod 15 is fixedly provided on the outer wall of the limit plate 6. The support rod 15 is a square support rod, and a movable plate 8 is slidably sleeved on the rod wall of the support rod 15. An insertion rod 9 is fixedly provided on the back side of the movable plate 8. A plurality of slots 10 for mating with the insertion rod 9 are provided on the inner wall of the rotating groove. The rod wall of the insertion rod 9 is arranged in the through hole, and the end away from the limit plate 6 passes through the through hole and is plugged into the slot 10. A spring 11 is sleeved on the rod wall of the support rod 15, and the two ends of the spring 11 are respectively fixedly connected to the support rod 15 and the movable plate 8.
[0030] Before the wheel body 1 is used and installed, the limit plate 6 is set vertically, and the plug rod 9 is plugged into the upper slot 10. When the traction rope is set, the movable plate 8 is pulled to slide along the support rod 15 and the plug rod 9 is pulled out from the upper slot 10. At this time, the spring 11 is compressed. When the limit plate 6 is rotated to a horizontal position, the movable plate 8 is released. Under the elastic force of the spring 11, the plug rod 9 is inserted into the left slot 10 to fix the position of the limit plate 6.
