Abstract
The utility model discloses a transfer rope device of many ropes of console mode friction lifting machine in rope device technical field, by the head sheave axle, a bearing, the bearing frame, the displacement sleeve, but variable diameter guide pulley, the spring etc. constitute, the head sheave axle passes through the bearing, the bearing frame is fixed in the frame, the spring is installed to the axle both sides, the variable diameter guide pulley of several and distance sleeve are installed in the centre in proper order, when certain wire rope atress is bigger than normal, the device can directly make the diameter at wire rope place head sheave guide pulley diminish, the head sheave guide pulley diameter grow at the too little wire rope place of atress simultaneously, balanced tension is poor. The utility model discloses simple structure, safe and reliable, transfer the rope convenient operation, can realize each wire rope's tension balance.
Description
Technical Field
The utility model relates to a mine winder field, concretely relates to console mode multi-rope friction hoist's accent rope device.
Background
The mine hoisting equipment is one of necessary equipment of a mine production system, has the main task of hoisting coal (or ore), gangue, conveying materials, lifting personnel and equipment and the like along a shaft, is one of large-scale fixed equipment of a mine, is a junction for connecting a mine underground production system and a ground industrial square and is directly related to coal production and even personnel safety in safe operation of a throat for mine transportation. As important equipment for mine production, the floor type multi-rope friction hoist is developing towards the intelligent direction, the application of the rope adjusting device can timely deal with the problem of unbalanced stress of the steel wire rope, hidden dangers can be prevented, regular inspection and maintenance are not needed, and economic loss caused by overhaul and production halt is reduced.
The length of the rope of the cushion type rope adjusting device is only integral multiple of the thickness of the cushion block each time, so the rope adjusting effect is not ideal; the screw rope adjusting device has the advantages that the screw cannot rotate due to rusting, corrosion and the like, and the device is only suitable for mines with small hoisting rigidity and small terminal load; chinese patent CN114940430A discloses a self-excited rope adjusting device, which can achieve a self-excited pulling force closed loop, but the structure is too complex.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a rope adjusting device of a floor type multi-rope friction hoist, which solves the problems of uneven stress of each steel wire rope, short service life of the steel wire rope and the like of the floor type multi-rope friction hoist; in addition, the device also has the advantages of simple structure, safety, reliability, quick response and the like.
The utility model adopts the following technical scheme: the rope adjusting device comprises a main rope adjusting part arranged on a head sheave shaft, and a bearing for connecting the head sheave shaft with a bearing seat, wherein the bearing is mainly used for connecting a rope adjusting head sheave and a rack. The rope adjusting part mainly comprises a reducing guide wheel, a distance sleeve for keeping the distance between the variable-distance guide wheels and a return spring for returning the variable-distance guide wheels.
Furthermore, the connection of the crown wheel shaft, the reducing guide wheel, the distance sleeve, the return spring and other parts belongs to split connection, and the parts are easy to replace when a problem occurs.
Furthermore, the top wheel shaft is connected with the bearing seat through the bearing, so that the friction between the top wheel shaft and the bearing seat can be reduced, and the energy loss is effectively reduced.
Compared with the prior art, the invention has the beneficial effects that:
(1) The rope adjusting device of the floor type multi-rope friction hoist adopts the variable-diameter guide wheel as the guide wheel of each rope of the head sheave, and has the advantages of simple structure, quick response, safety, reliability and the like;
(2) The rope adjusting device of the floor type multi-rope friction hoist can automatically adjust the diameter of the guide wheel where the steel wire rope is located according to the stress of each steel wire rope, and manual intervention is not needed.
Drawings
Fig. 1 and fig. 2 are a front view and a left view of a rope adjusting device of a floor type multi-rope friction hoist of the present invention, respectively;
in the figure:
1 day wheel axle, 2 bearings, 3 bearing seats, 4 distance sleeves, 5 reducing guide wheels, 6 reset springs and 7 elevator steel wire ropes.
Detailed Description
The features and principles of the present invention will be described in detail below with reference to the accompanying drawings, and the illustrated embodiments are only for explaining the present invention, and do not limit the scope of the present invention.
As shown in the figure, the rope adjusting device of the floor type multi-rope friction hoist comprises a main rope adjusting part arranged on a head sheave shaft 1, a bearing 2 connecting the head sheave shaft 1 with a bearing seat 3, and the bearing seat 3 is mainly used for connecting a rope adjusting head sheave and a frame.
The rope adjusting part mainly comprises a reducing guide wheel 5, a distance sleeve 4 for keeping the distance between the variable-distance guide wheels 5 and a return spring 6 for returning the variable-distance guide wheels 5.
When the tension born by a certain steel wire rope in the steel wire ropes 7 of the elevator is greater than that of other steel wire ropes, the steel wire ropes can downwards extrude the reducing guide wheel 5 due to too large tension, the reducing guide wheel 5 where the steel wire rope with too large tension is located enables the two sides of the reducing guide wheel 5 to outwards move under the action of the gravity of the steel wire rope, the effective radius of the steel wire rope is reduced, and the two sides of the reducing guide wheel where the steel wire rope with too small tension is located inwards move due to too small stress of other steel wire ropes, and the effective radius of the steel wire rope is increased. Thereby the unbalanced problem of tension of each wire rope that can be better solution.
