Description
Technical field
The utility model relates to elevator technology field, is specifically related to a kind of traction pendant line.
Background technology
Elevator is the sports equipment for carrying certain load, and along with the development of elevator technology, drawing belt will progressively replace traditional steel rope, and the main flow becoming elevator traction pendant line is selected.
Drawing belt compares steel rope, has the clear superiority as traction pendant line, but if drawing belt designs improper, also can there are some shortcomings, and particularly superfluous the and roller of traction coordinates the noise problem brought with drawing belt.
Existing drawing belt, can be divided into two classes according to driving surface (face namely contacted with traction sheave or track adjusting wheel):
One, there is biplanar drawing belt.
Application publication number is that the patent of invention document of CN 1346329 A discloses a kind of biplanar flats composite steel band, and two inornate planes of composite steel band are all driving surfaces, and one of them plane contacts with traction sheave, and another plane contacts with track adjusting wheel.
Authorization Notice No. be the patent of invention document of CN 100509602 C disclose another kind of structure there is biplanar flats composite steel band, one of them plane is with the discontinuous groove perpendicular with elevator service direction, and another plane does not add any modification.
Two planes of the composite steel band in these two patents are all driving surface, contact with traction sheave or track adjusting wheel respectively, in running process of elevator, when composite steel band contact traction sheave or track adjusting wheel, air can be involved between composite steel band and traction sheave or track adjusting wheel, due to the outside coated softer composite material of steel band, the outside face of steel band is caused to there will be compressive deformation to a certain degree, indrawn air is compressed, when composite steel band departs from traction sheave or track adjusting wheel, air discharges by the contact surface of composite steel band and traction sheave or track adjusting wheel, along with the High Rotation Speed of traction sheave and track adjusting wheel, air is repeatedly by compression release, affect the normal operation of elevator on the one hand, continuous print noise can be produced on the other hand, this noise imports in car, have a strong impact on the comfort taken, therefore, the composite steel band of this biplane construction is not suitable for the track adjusting wheel of elevator, especially car track adjusting wheel.
Two, at least one wears the drawing belt of convex tendon.
Application publication number is that the patent of invention document of CN 102264623 A discloses a kind of belt, and one side is tissue layer, and another side is the face of band convex tendon, and this face is the driving surface of belt.
Because tissue layer resistance to abrasion is inadequate, be not suitable for track adjusting wheel or traction sheave with the use of, therefore, in use, the side of band convex tendon can only be adopted as driving surface, may need to reverse around its longitudinal axis, owing to bearing twisting resistance for a long time in process around the home, inner force-summing element discontinuity, the service life of belt shortens greatly.
The utility model patent document of Authorization Notice No. to be the utility model patent document of CN 201254671 Y and publication number be CN202247494U discloses a kind of hoisting rope for elevator of double-sided belt convex tendon, and two faces are driving surface.
This have a traction pendant line wearing convex tendon at least, when reality uses, using the face of band convex tendon as driving surface, compare plane or be with discontinuous groove flat to make driving surface, the area of contact of traction pendant line and traction sheave is excessive, when calculating elevator device traction, there is the problem of traction surplus, under the emergency work condition at the counterweight crouching end, traction pendant line can not skid, and causes car to be promoted, there is potential safety hazard, if eliminate this hidden danger, need additionally to increase safety device, cause elevator cost to increase further.
