However, this vertical continuous production does not take into account that when the elevator is actually used, the requirements for both ends and the middle are different.
When the elevator car is at the top or bottom of the hoistway, the load conditions are relatively harsher, the starting and braking are more frequent, and the acceleration or deceleration is too large, so in this case, slippage is often caused by insufficient traction of the elevator At the same time, the wear at both ends of the traction belt will also increase, thus affecting its overall strength
In view of the difference between the working conditions of the elevator in the starting (or braking) stage and the high-speed stage, the existing traction belt with uniform longitudinal structure can no longer meet the requirements of making the elevator run efficiently in the middle and both ends of the hoistway

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention, and the drawings are only for the purpose of illustration, and are not drawn according to the original scale.
[0021] like figure 1 As shown, this embodiment provides a wear-resistant lifting member for an elevator, which is a longitudinal steel belt structure, including a tensile body 1, a coating material 2 and a friction body 3, wherein the tensile body 1 is set There are multiple wire ropes, specifically steel wire ropes extending longitudinally along the steel belt, which are used as the supporting part of the lifting member; th...

The invention discloses an abrasion-resisting lifting piece for an elevator. The lifting piece is of a longitudinal steel belt structure and comprises a plurality of anti-pulling bodies extending in the longitudinal direction, and a coating material wrapping the anti-pulling bodies. Concave-convex friction bodies are arranged at the two ends of the longitudinal steel belt structure. The friction bodies are located on the surfaces of the two sides of a steel belt and used for being matched with the inner side faces of elevator traction wheels. The friction body structures are arranged at the two ends of the steel belt, so that friction force between the steel belt and the traction wheels is increased. In the using process, the engagement between the steel belt and the traction wheels is tighter, and the phenomenon that when an elevator is braked or started, slipping happens due to insufficient traction force is avoided; and running stability and reliability of the elevator are effectively guaranteed. Meanwhile, the steel belt is endowed with better abrasion resistance through the structure of the friction bodies, and the service life of the steel belt is greatly prolonged.
Description
technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a wear-resistant lifting member for an elevator. Background technique [0002] Belt tension parts for elevators have been applied in the domestic market, and there are many related patents, but the belt products involved in these patents are all longitudinally uniform structures, such as patent "99803362.6 Tension parts for elevators", " 99814864 Elevator Tensile Components", "200480039990.4 Elevator Equipment" and "200310104380.5 Drivable Bearing or Traction Device and Manufacturing Method", the steel core embedded in the tensile part and its coating layer in the above patents are all uniform, The production process also adopts continuous extrusion production. [0003] The advantage of this structure is that the manufacturing process is relatively simple, and the requirements for equipment and processes are relatively low. However, this vertical continuous productio...
