Definitions

  • the invention relates to a pressure-equalising device of steel rope sets for an elevator, and more particularly, to a two nodal pressure-equalising device of two steel rope sets for an elevator capable of adjusting a pressure sustained to two steel rope sets and enabling the pressure sustained between these two steel rope sets to be the same.
  • a traction elevator suspending and lifting system is composed of a traction wheel, a steel rope set, a car platform sill, a balance block system and other main parts; a friction pressure generated by winding each steel rope of the steel rope set in a groove of the traction wheel in the traction elevator suspending and lifting system provides a power for the car platform sill to lift up or down; under the adjustment that the elevator driving technology keeps developing, both the lifting height of the elevator and the running speed are greatly improved, at the same time, higher requirements are also proposed on the safety and the reliability of the elevator.
  • the pressure sustained to each steel rope in the steel rope set shall be the same in the using process of the elevator, and the shape and the size of the groove for winding the steel rope on the traction wheel shall also be the same; but in the actually using process, the pressure sustained to each steel rope in the steel rope set shall be different due to various reasons, this results in a situation that some steel ropes are pressured highly and some steel ropes are pressured lowly; the friction pressure between the highly-pressured steel rope and the groove on the corresponding traction wheel will relatively higher, this results in a condition that the friction of the groove on the corresponding traction wheel is more severe, so the shape and the size of the groove on the corresponding traction wheel are changed over time, resulting in that the highly-pressured steel rope is pressured more and more in work.
  • the steel rope will move less than 0.314mm; by taking the 20-storey building for example, the traction wheel will rotate about 100 turns, so the steel rope will move less than 31.4mm.
  • the steel rope will pressured more than about 3000N; when the steel rope in the steel rope set is pressured unevenly, a wriggling phenomenon is generated between the lowly-pressured steel rope and the traction wheel, the wriggling between the steel rope and the traction wheel will cause the abrasion of the steel rope and the traction wheel; the higher the storey is, the more severe the situation above becomes.
  • the highly-pressured steel rope used for a long time is easy to break in the using process, resulting in safety accidents of the elevator; at the same time, the lowly-pressured steel rope will also be damaged due to the abrasion of the traction wheel. If the damage is severe, the steel rope will also be broken to result in the safety accidents of the elevator; for this reason, we develop a two nodal pressure-equalising device of steel rope sets for an elevator capable of adjusting the pressure to two steel rope sets and enabling these two steel rope sets to pressure the same.
  • the object of the invention is to overcome the shortages of the prior art and is intended to provide a two nodal pressure-equalising device of steel rope sets for an elevator capable of adjusting the pressure to two steel rope sets and enabling these two steel rope sets to pressure the same.

  • two spherical cavities are symmetrically provided on the pressure-equalising device main body; the spherical nodal point is arranged in each spherical cavity, and cam rotate.
  • the lower portion of the pressure-equalising device main body is provided with a rotating mount; the centre line of the pressure-equalising device main body and the centre line of the rotating mount are collinear; the bottom of the rotating mount is provided with an arc-shaped bump; the base seat is provided with an arc-shaped groove; and when the arc-shaped bump is arranged in the arc-shaped groove, the arc-shaped bump can rotate around the arc-shaped groove.
  • the pressure-equalising device main body is opened with a screw hole, and a screw can fix the rotating mount at the lower portion of the pressure-equalising device main body via the screw hole.
  • the base seat is uniformly distributed with fixed holes to conveniently mount the base seat.
  • the centre of the spherical nodal point is provided with a through hole for accommodating the steel rope.
  • the present invention has the following advantages compared to the prior art:

  • two spherical cavities 2 are symmetrically provided on the pressure-equalising device main body 1 along the centre line; the spherical nodal point 8 is arranged in each spherical cavity 2 and can rotate;
  • the lower portion of the pressure-equalising device main body 1 is provided with a rotating mount 4;

  • the arc-shaped bump 6 can also be set as a spherical bump, and the corresponding arc-shaped groove 7 is set as a spherical groove.
  • the present invention has the following advantages compared with the prior art: according to the two nodal point pressure-equalising device of the steel rope sets for the elevator described in the present invention, wherein the pressure-equalising device main body is rotatably provided on a base seat to balance the pressures at both ends thereof by wiggling around the rotation centre; two spherical nodal points are symmetrically provided on the pressure-equalising device main body; the centre of the spherical nodal points is provided with a through hole; the through hole is used for mounting a steel rope; the spherical nodal points can rotate or wiggle around the pressure-equalising device main body; the rotation centre of the pressure-equalising device main body is located on the centre line thereof; and the rotation centre of each spherical nodal point is on the same horizontal plane as the rotational centre of the pressure-equalising device main body and is collinear.
  • the two nodal point pressure-equalising device enables each independent traction steel rope to have a mechanics relationship correlative to the other steel rope by means of an oscillating bar and the lever principle, i.e., the change in the pressure sustained to any steel rope will transmit to the spherical nodal points under the condition that the pressure is sustained to the traction steel rope set, and the spherical nodal point is pressured to wiggle to enable the pressure-equalising device main body to lose balance to wiggle around the rotation centre.
  • the device according to the solution of the present invention can adjust the pressure sustained by two sets of steel ropes, and when a stable state is reached, the pressure sustained by two steel rope sets will be the same, thereby enabling the damage caused by unequal pressure sustained by the steel rope set for the elevator to be overcome, increasing the service life of the steel ropes, and improving the safety of the elevator.
