Problems solved by technology

However, because the length of the elevator wire rope changes very slightly, the trigger sensitivity of the existing automatic wire rope tensioning device is not high, and it cannot respond quickly to the change of the elevator wire rope and tension it in time, which makes the elevator have certain safety hazards

Abstract

The invention discloses an automatic tension adjusting system for an elevator wire rope. The system comprises a first cross beam (1), wherein first sliding chutes (2) are formed in the first cross beam (1), first high-strength springs (3) are arranged in the first sliding chutes (2), a first moving beam (4) is fixed on the first high-strength springs (3), and a lower pulley block (6) consisting of multiple lower pulleys (5) is arranged on the first moving beam (4); a pulley upper beam (7) is arranged above the first cross beam (1), an upper pulley block (9) consisting of multiple upper pulleys (8) is arranged on the pulley upper beam (7), and the upper pulley block (9) and the lower pulley block (6) are wound with the elevator wire rope (10). The automatic tension adjusting system for the elevator wire rope has the characteristics of high trigger sensitivity, quick response and rapid tension compensation, and further, the system can supply higher lifting power with smaller travel change so as to effectively tension the wire rope.

Description

technical field [0001] The invention relates to an automatic tension adjustment system, in particular to an elevator wire rope automatic tension adjustment system. Background technique [0002] In a climate with a large temperature difference, the length change of the elevator wire rope due to thermal expansion and cold contraction is very obvious. When the temperature does not change, the elevator wire rope will also be extended and its length will change after long-term use. Therefore existing elevator is generally provided with wire rope automatic tensioning device at the suspension wire rope end, is used for adjusting the elongation of compensation elevator wire rope, can guarantee the safe and stable operation of elevator. However, because the length of the elevator wire rope changes very slightly, the trigger sensitivity of the existing automatic wire rope tensioning device is not high, and it cannot respond quickly to the change of the elevator wire rope and tension i...
