Abstract

The present invention relates to a horizontally movable vertical shaft rope guide and a regulating method thereof, which are suitable for guiding of hoisting containers in vertical shafts. The vertical shaft rope guide comprises a hoisting rope, and two hoisting containers suspended from the tail ends of the hoisting rope, wherein, cage guide ropes are led through guide cage lugs arranged on the two sides respectively, a tensioner arranged on the ground at the shaft top is connected to the upper end of each cage guide rope, and a connector arranged under a steel slot at the shaft bottom is connected to the lower end of each cage guide rope; a hydraulic cylinder is connected at the other side of each tensioner and the corresponding connector, and the hydraulic cylinder is connected to the tensioner or connector. During hoisting in the vertical shaft, the hydraulic cylinders are controlled to act in advance, to push the tensioners or connectors to move towards the center between the two hoisting containers, so that the cage guide ropes led through the guide cage lugs on the two sides of the hoisting containers get close to each other at the same time and wrap the hoisting container; thus, the horizontal displacement of the hoisting containers is restrained, and the impact of air flow on the two hoisting containers is minimized when the two hoisting containers meet.

First claim

The invention claimed is:

1. A rope guide system that is configured to be horizontally moveable in a vertical shaft that extends downward from a ground level, comprising:
a hoisting rope ( 1 ) having two tail ends;
two hoisting containers ( 2 ); a first hoisting container and a second hoisting container ( 2 ) that are each suspended from one of the tail ends of the hoisting rope ( 1 ); wherein the first hoisting container ( 2 ) and the second hoisting container ( 2 ) are arranged, so that when the first hoisting container ( 2 ) runs up vertically in the vertical shaft the second hoisting container ( 2 ) run down vertically in the vertical shaft and when the second hoisting container ( 2 ) runs up vertically in the vertical shaft the first hoisting container ( 2 ) runs down vertically in the vertical shaft;
cage guide ropes ( 3 ) that extend from a top of the vertical shaft to a bottom of the vertical shaft guide motion of the hoisting containers ( 2 );
tensioners ( 4 - 1 ) positioned on the ground level at the top of the vertical shaft connected to a top end of each of the cage guide ropes ( 3 );
connectors ( 4 - 2 ) positioned at the bottom end of the vertical shaft connected to a bottom end of each of the cage guide ropes ( 3 ), each connector ( 4 - 2 ) having a corresponding tensioner ( 4 - 1 ) connected to an opposite side of the cage guide rope ( 3 );
a steel slot ( 5 ) at the bottom of the vertical shaft for holding the connectors ( 4 - 2 ) underneath the steel slot ( 5 ) at the bottom of the vertical shaft;
wherein each of the hoisting containers ( 2 ) comprises guide cage lugs ( 2 - 1 ) that are arranged symmetrically on two opposite sides of each of the hoisting containers ( 2 ); the cage guide ropes ( 3 ) are configured to be led through the guide cage lugs ( 2 - 1 ) on the two opposite sides respectively to guide the hoisting containers ( 2 );
wherein hydraulic cylinder ( 4 - 3 ) is connected to a side of each connector ( 4 - 2 ) and each of the corresponding tensioners ( 4 - 1 ); and
wherein each hydraulic cylinder ( 4 - 3 ) is configured to move the tensioners ( 4 - 1 ) and the connectors ( 4 - 2 ) horizontally toward a center of the vertical shaft between the first hoisting container ( 2 ) and the second hoisting container ( 2 ) when the two hoisting containers ( 2 ) are about to pass each other while moving in opposite directions in the vertical shaft, so that the cage guide ropes ( 3 ) that are led through the guide cage lugs ( 2 - 1 ) arranged on the two opposite sides of the hoisting containers ( 2 ) move horizontally toward the center simultaneously and apply a lateral force oriented to the center of the vertical shaft on the hoisting containers ( 2 ) to counteract air flow pressure on the two hoisting containers ( 2 ) when the two hoisting containers ( 2 ) pass each other.

2. The system according to claim 1 , wherein, there are 4 or 8 guide cage lugs ( 2 - 1 ) arranged symmetrically on the two opposite of the hoisting container ( 2 ).

3. The system according to claim 1 , wherein, the tensioner ( 4 - 1 ) and connector ( 4 - 2 ) comprise rollers ( 4 - 4 ) arranged symmetrically on a bottom of the tensioner ( 4 - 1 ) and connector ( 4 - 2 ) to enable the tensioner ( 4 - 1 ) and connector ( 4 - 2 ) to move horizontally towards the center simultaneously.

4. A regulating method of a rope guide system, comprising:
a) providing a rope guide system comprising:
a hoisting rope ( 1 ) having two tail ends;
two hoisting containers ( 2 ); a first hoisting container and a second hoisting container ( 2 ) that are each suspended from one of the tail ends of the hoisting rope ( 1 ); wherein the first hoisting container and the second hoisting container are arranged so that when the first hoisting container ( 2 ) runs vertically in the vertical shaft the second hoisting container ( 2 ) runs down vertically in the vertical shaft and when the second hoisting container ( 2 ) runs up vertically in the vertical shaft the first hoisting container ( 2 ) runs down vertically in the vertical shaft;
cage guide ropes ( 3 ) that extend from a top of the vertical shaft to a bottom of the vertical shaft to guide motion of the hoisting containers ( 2 );
tensioners ( 4 - 1 ) positioned on the around level at the top of the vertical shaft connected to a top end of each of the cage guide ropes ( 3 );
connectors ( 4 - 2 ) positioned at the bottom of the vertical shaft connected to a bottom end of each of the cage guide ropes ( 3 ), each connector ( 4 - 2 ) having a corresponding tensioner ( 4 - 1 ) connected to an opposite side of the cage guide rope ( 3 );
a steel slot ( 5 ) at the bottom of the vertical shaft for holding the connectors ( 4 - 2 ) underneath at the bottom of the vertical shaft;
wherein each of the hoisting container ( 2 ) comprises guide cage lugs ( 2 - 1 ) that are arranged symmetrically on two opposite sides of each of the hoisting containers ( 2 ); the cage guide ropes ( 3 ) are configured to be led through the guide cage lugs ( 2 - 1 ) on the two opposite sides respectively to guide the hoisting containers ( 2 );

b) connecting a hydraulic cylinder ( 4 - 3 ) to each connector ( 4 - 2 ) and each of the corresponding tensioners ( 4 - 1 );
c) when the two hoisting containers ( 2 ) are about to pass each other while moving in opposite directions in the vertical shaft controlling the hydraulic cylinders ( 4 - 3 ) to move the tensioners ( 4 - 1 ) and the connectors ( 4 - 2 ) horizontally toward a center of the vertical shaft between the first hoisting container ( 2 ) and the second hoisting container ( 2 ), so that the cage guide ropes ( 3 ) dual are led through the guide cage lugs ( 2 - 1 ) arranged on the two opposite sides of the two hoisting containers ( 2 ) move towards the center simultaneously and apply a lateral force oriented to the center of the vertical shaft on the hoisting containers ( 2 ) to counteract air flow pressure of the two hoisting containers ( 2 ) when the two hoisting containers ( 2 ) pass each other.

5. The regulating method of claim 4 , wherein, the hydraulic cylinders ( 4 - 3 ) a controlled to act 3-8 seconds in advance of the two hoisting containers ( 2 ) passing each other.
