Embodiment 2

[0047] A method for installing a high-speed elevator compensating rope tensioning device, comprising the following steps,

[0048] (1) Drill holes on the ground of the well pit, fix the base 6 of the tensioning device on the ground of the well pit through expansion screws, and the tension pulleys 2 on both sides correspond to the positions of the car and the counterweight vertical suspension compensation wire rope respectively;

[0049] (2) Adjust the position of the diagonal tie rod 12 through the bolts on the diagonal tie rod seat 11, so that the axes of the tension pulleys 2 on both sides are on the same plane, pass the compensation wire rope through the tension pulley 2 on both sides, and compensate one end of the wire rope It is connected to the center of gravity of the car, and the other end is connected to the center of gravity of the counterweight frame;

[0050] (3) Adjust the tension of the spring 16 by turning the adjusting screw 18 to drive the balance baffle 17 up...

Embodiment 3

[0054] A high-speed elevator, including the high-speed elevator compensating rope tensioning device described in embodiment 1, the high-speed elevator compensating rope tensioning device described in embodiment 1 is installed and connected according to the method described in embodiment 2.

Abstract

The invention relates to a high-speed elevator compensating rope tensioning device and application thereof. The high-speed elevator compensating rope tensioning device comprises a base, fixed guide rails symmetrically arranged on the two sides of the base, and a balance baffle arranged above the base; a tensioning mechanism is arranged between the base and the balance baffle, is positioned between the fixed guide rails on the two sides, is connected with the fixed guide rails in a sliding manner, and comprises a tightening wheel fixing device, tightening wheels arranged on the two sides of the tightening wheel fixing device, and a balancing weight arranged at the bottom of the tightening wheel fixing device; the top part of the tightening wheel fixing device is connected with the balance baffle through an elastic component. Compared with the prior art, the elevator tensioning device is directly mounted on a pit floor, so that the occupied area is small, and the mounting is flexible. A pair of safety tongs is replaced with a flexible balance device, so that the operation of an elevator is more comfortable. In addition, the weight of an original steel plate is replaced with the additionally arranged balancing weight, so that the device is not only more flexible, but also convenient to mount, and meanwhile, the cost is reduced.

Description

technical field [0001] The invention relates to a high-speed elevator compensating rope tensioning device and an application thereof, belonging to the technical field of elevators. Background technique [0002] The compensation rope tensioning device is mainly used for high-speed elevators. The existing tensioning device is generally connected to the guide rail and braked with a safety gear. Components such as raised seats and guide rail brackets interfere. [0003] For example, Chinese patent document CN202848803U discloses a tensioning device for high-speed elevator compensation ropes, which mainly includes a guide rail support frame, a tensioning wheel bracket, a lower limit safety switch, an upper limit baffle, a tensioning wheel and a balance weight. The lower limit switch is used to detect the elongation of the compensation rope to prevent elevator safety accidents caused by the elongation and bottoming of the compensation rope. The upper limit baffle is used to limit...
