Description

one

The invention relates to chess lifting installations, in particular to a method for replacing their ropes.

Methods are known for replacing a rope on multi-aerial lifting installations by descending into the barrel of a suspended rope with its subsequent fastening on a vessel and ascent to the surface of the exchangeable one.

However, the known methods require a significant amount of auxiliary work on the installation of vessels on the beams and the release of the traction sheave from the ropes.

The purpose of the invention is to reduce the complexity of work when replacing ropes.

This goal is achieved by attaching one end of the replaceable and hanging ropes to the vessels while they are in the extreme lower and upper positions respectively, and the free ends of the ropes respectively to the receiving and feeding drums and moving the vessels from one extreme to the other. .

FIG. Figures 1 and 2 show a multi-cable lifting installation with equipment for replacing ropes at different times of performing operations for replacing a lifting rope; in fig. 3-6 - the same, when replacing the balancing rope.

The change of the lifting rope is performed as follows. The receiving and feeding drums 1, connected kinematically, are set at zero. The suspension cable 2 of the required length is pre-wound on the feed drum and at one end

attached to it. The vessel 3 of the lifting installation closest to the drums is set at the level of the zero platform. The replaceable rope 4 is detached from the vessel and attached to the receiving drum. The hanging rope is attached to the vessel at the site of the uncoupled replaceable rope. If necessary, deflecting rollers 5 are used. This completes the execution of auxiliary operations. FIG. 1 shows the position of the lift

installation before the start of the working operation. When you move the vessels 3, the coiled rope 2 is rolled up from the supply drum and fed into the barrel. At the same time, lifting from the barrel and winding

to the receiving drum of the interchangeable rope 4. FIG. Figure 2 shows the position of the lift unit at the time of the end of the working stroke. After ferrying vessels 3, the hanging rope 2 is attached at the level of the zero platform.

to the reinforcement of the trunk, the interchangeable rope 4 is uncoupled from the vessel in the upper position, in its place a hanging rope is fastened through the drum, after which the rope is separated from the reinforcement

the trunk.

When replacing the balance of the rope on the surface of the earth (see Fig. 3), the receiving and feed drums 1, kinematically interconnected, are installed and mounted south of the tower copra. Hanging rope 2 of the required length is wound on the bottom, drum ny. The vessel 3 on the installation side of the drums is lifted as far as possible up to the slide machine. The replaceable rope 4 is attached to the armnrovka of the barrel at the level of the bullet pad and is uncoupled from the upper and pizhiego vessels. The upper end of the blended cable is fastened to the receiving drum, after which it is separated from the amiming of the barrel. The upper vessel (see Fig. 3) is distilled to the lowest position (see Fig. 4). The hanging rope 2 is guided by deflecting rollers 5 through the traction sheave of the machine and the inclination towards the vessel, which is in its extreme upper position. The replaceable rope 4 with the lower end is attached to the second vessel. They choose a weak rope and create the necessary tension.

The lifting machine carries out distillation of vessels 3 (see Fig. 5). At the same time, the hanging rope 2, winding up from the feed drum, is fed into the trunk, and the interchangeable rope 4 is removed from the trunk and reeled up onto

welcome drum After the vessels are driven, the hanging rope 2 is attached to the trunk reinforcement at the zero mark, it is uncoupled from the lower vessel 3 and the supply drum and

the end of the kapat, which surrounds the machine, is removed from the drip pulley and placed in the bay at the zero platform. The replaceable rope 4, 11, which is moored on the take-up drum, is detached from the vessel. The vessels are again distilled.

(see. G). After the vessels are not transported to the extreme but not attached, the rope 2 is attached to them and is separated from the trunk reinforcement.
