Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The invention provides a traction system for an elevator, which includes a traction machine 1 installed in the elevator shaft, a traction wire rope 2 and a counterweight 3 arranged under the traction machine 1, and is characterized in that: the traction wire rope One end of 2 is fixed to the inner wall of the elevator shaft, the other end of the traction wire rope 2 is fixed to the counterweight 3, and the middle part of the traction wire rope 2 is wound around the guide wheel 4.1 at the bottom of the car 4 and the center of the traction machine 1 in turn. On the driving wheel 1.1, surface treatment mechanisms for treating the surface of the traction wire rope 2 are provided between the counterweight 3 and the driving wheel 1.1 and between the guide wheel 4.1 of the car 4 and the driving wheel 1.1;

[0025] The surface treatment mechanis...

Abstract

The invention discloses a dragging system for an elevator. The dragging system comprises a dragging system, a dragging steel wire rope and a counterweight filler weight. The dragging system is characterized in that surface processing mechanisms for processing the surface layer of the dragging steel wire rope are respectively arranged between the counterweight filler weight and a driving wheel, as well as between guiding wheels of a lift car and the driving wheel; each of the surface processing mechanisms comprises a spraying mechanism and a wax removing mechanism; an annular groove allowing the dragging steel wire rope to be surrounded on the corresponding guiding wheel is formed in an outer periphery wall of the corresponding guiding wheel; at least three clamping grooves formed by internal tangency in the radial direction of the corresponding guiding wheel are formed in the position at the bottom of each annular groove; and a clamping block is arranged in the corresponding clamping groove, and the dragging steel wire rope is abutted to or separated from the upper end surfaces of the clamping blocks along with the rotation of the guiding wheels. According to the dragging system for the elevator provided by the invention, based on the condition that frictional force between the dragging steel wire rope and the driving wheel is not influenced, the protective performance of the surface layer of the dragging steel wire rope is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a traction system for elevators. Background technique [0002] The lifting process of the elevator is to wind the driving wheel of the traction machine, the guide wheel of the car and the counterweight wheel of the counterweight in sequence through the traction wire rope, so as to drive the movement of the car through the friction between the driving wheel and the traction wire rope. lift. As a special equipment, the safety of the elevator is directly related to the life safety of passengers. Therefore, the requirements for elevator repair and maintenance are high, that is, the frequency of maintenance is high, the service life of parts is short, and the replacement of vulnerable parts High frequency. And the elevator needs to lock the car and the counterweight during the maintenance process, so as to facilitate the loosening of the traction wire rope, and realize the inspect...
