Problems solved by technology
Theoretically speaking, using this method to release the rope will have a very good effect and high work efficiency; however, there will be many problems in the actual application: first, there needs to be a place to place all the wooden ropes outside the hall door on the top floor. Enough space for the reel, and the distance between the wooden reel and the elevator shaft must be far enough to guide all the wire ropes into the car anti-rope pulley at the same time; second, a large number of installation personnel are required, and each wooden reel needs to be equipped with at least one thirdly, because all the wire ropes are laid out at the same time, the required safety protection measures must be very strict, such as: how to prevent the wire ropes from falling rapidly due to their own weight; finally, it is only suitable for use on newly installed elevators, and it is not suitable for replacing old elevators. Not suitable for ladder wire rope

The invention relates to a reel-off method and a reel-off mechanism for an elevator steel wire rope in the technical field of elevators. According to the reel-off method, a first steel wire rope at a counter-weight side is pulled by a rope guide rack, and a subsequent steel wire rope is connected with the first steel wire rope through a rope guide piece to realize guide reeling off. The reel-off mechanism comprises a reel-off rack, a counter-weight side rope guide mechanism, a cage side rope guide mechanism and a counter-weight diversion sheave which is arranged in a well pit, wherein the counter-weight side rope guide mechanism comprises a first pulley, a rope gripper, a guide wheel and the rope guide rack or the first steel wire rope used as a rope reel-off guide; the first pulley is arranged on the top of an engine room; and the rope guide rack is arranged between two rows of counter-weight guide rails in an elevator shaft. The reel-off mechanism is simple and reliable, and is high in the efficiency and the safety; and in the whole reel-off process, routes passed by the steel wire rope are all provided with a guide and protection device, so that the reel-off effect is excellent, the steel wire rope has no mechanical injuries in the whole process so as to be small in distortion.
Description
technical field [0001] The present invention relates to a method and a device in the field of elevator installation technology, in particular to a wire rope unwinding method and a rope unwinding mechanism applied to an elevator with a traction ratio of 2:1. Background technique [0002] In the field of elevator construction, the quality of elevator wire rope installation has a great impact on its life. From the field investigation and analysis, almost 70% of the early damages of steel wire ropes are caused by improper installation operations; therefore, reasonable rope laying plays a vital role in improving the service life of steel wire ropes. Especially on the high-rise elevator with a traction ratio of 2: 1, because the steel wire rope is very long, how to ensure that the steel wire rope is not damaged during the whole rope-releasing process has more practical significance. [0003] In an elevator with a traction ratio of 2:1, the commonly used wire rope laying method is...
