Embodiment Construction

[0034] Hereinafter, the form for carrying out the main rope replacement method of the elevator of this invention is demonstrated based on drawing. In addition, the same code|symbol is attached|subjected to the part which overlaps with the description of the said prior art.

[0035] An elevator applying an embodiment of the main steel rope replacement method of the elevator of the present invention includes: for example image 3 Shown are a car 27 installed on the hoistway 100 and stopped on each floor; a counterweight 20 suspended via the car 27 and main ropes 4 ; and a pair of guide rails 21a, 21b guiding the counterweight 20 . Furthermore, in this embodiment, the elevator is constituted by a 2:1 roping ratio elevator, and as will be described later, the main rope replacement work of this embodiment is mainly performed on the uppermost floor 103a among the floors. and the lowermost laminate 103b. In addition, a plurality of main steel cables 4 are erected.

Abstract

The invention provides a main tightwire replacing method of elevator, which can be rapidly used for replacing the main tightwire, and reducing cost. The method employs a main tightwire replacing fixture (11) for replacing the main tightwire, and the main tightwire replacing fixture comprises a cross-bar (6) which is arranged between guide rails and above a counter weight; guiding part (7a, 7b) which are fixed at double ends of the cross bar and isntalled on each guide rail; stringing pulley (2a, 2b) which wind the main tightwire for replacing and are isntalled on the cross-bar part; cable connecting mechenism (5a, 5b) which are equipped on the cross-bar and connect the used main tightwire. The method comprises the following processes: an installation process for holding down the new main tightwire from the machine room and installing the new main tightwire on the stringing roller; a connection process for connecting the used main tightwire to the tightwire connection mechanism; a moving process for moving the cross-bar part downwards.

Description

technical field [0001] The present invention relates to a main wire rope replacement method for replacing an old main wire rope to be replaced with a new main wire rope for replacement. Background technique [0002] Figure 6 It is a figure explaining the main rope replacement method of the conventional elevator. [0003] In general, elevators have: Figure 6 The liftway 100 shown; the machine room 101 provided on the upper part of the liftway 100 ; and the machine beam 102 provided in the machine room 101 . In addition, the elevator is further equipped with: a car 27 provided on the hoistway 100; a counterweight 20 that moves up and down relative to the car 27; and a pair of guide rails 21a, 21b that guide the counterweight 20. [0004] The machine room 101 includes: a traction machine (not shown) mounted on a machine beam 102 ; a hoist winch 26 rotated by being supplied with electric power; and a beam pulley 25 rotatably arranged near the hoist winch 26 . On the other h...
