Description
Technical Field
The utility model relates to an elevator traction mechanism, in particular to a traction mechanism for an anti-drop elevator.
Background
With the development of technology, the traction steel belt has been widely used as an elevator traction system by gradually replacing a steel wire rope due to the advantages of silence, attractive appearance, long service life, stable operation and the like compared with the traditional steel wire rope structure. The existing driving structure for dragging the steel belt mainly comprises a dragging shaft, dragging steel belt pulleys and dragging seats, wherein the dragging shafts are rotatably connected with the dragging seats at two ends of the dragging shaft, and the dragging steel belt pulleys are arranged on the dragging shaft side by side and respectively limit and guide each dragging steel belt. Meanwhile, in order to avoid the mutual slipping between the traction steel belt and the steel belt wheel, the two ends of the traction steel belt wheel are provided with corresponding friction limiting structures, and the friction limiting structures are as shown in patent 201510819747.4 and 201620822643.9.
However, this structure has a disadvantage in that the steel belt grooves on the respective steel belt pulleys cannot be completely aligned in the lateral position due to machining errors of the traction steel belt, the traction steel belt pulley, and installation errors between the steel belt pulleys at different positions in the elevator hoistway, and the opening size of the respective steel belt grooves cannot be completely matched with the width of the traction steel belt. This results in the traction steel belt being offset left and right with the positional error of the steel belt groove during installation and the side wall of the steel belt groove on the offset side being pressed during subsequent traction, thereby increasing the possibility of bending deformation of the traction steel belt during use. On the other hand, when the traction steel belt wheel receives extrusion force from the traction steel belt, friction damage of the traction steel belt at the extrusion part is further aggravated, so that a gap is formed between the traction steel belt and the steel belt groove after long-term use, and the anti-skid effect of the friction limiting structure is reduced.
Therefore, the existing anti-slip mechanism for the elevator traction steel belt has the problems of poor anti-slip stability and easiness in abrasion of the traction steel belt.
