Abstract

Подъемное устройство, включающее червячную лебедку, преимущественно действующую от мускульной силы человека, канат с девятикратным полиспастом или более того, который подвешивают, как можно ближе к центру тяжести устройства, которое состоит из собственно устройства и манипулятора, который требуется поднять к монорельсу у кровли горной выработки и закрепить на последнем, отличающееся тем, что, с целью увеличения надежности действия полиспастов подъемного каната, увеличения надежности подъема манипулятора и уравновешивания некоторой остаточной несбалансированной части веса манипулятора, девятикратный полиспаст выполняют с блоками, располагают блоки в шахматном порядке с наиболее параллельными ветвями каната с минимальным скрещиванием ветвей восходящих и нисходящих, а с целью уравновешивания некоторой остаточной несбалансированной части веса манипулятора, к его четырем угловым точкам подвеса закрепляют уравновешивающий канат, который представляет собой бесконечный канат, закрепленный за восходящие ветви к манипулятору, блоки которого закрепляют штанговыми крепями к почве и кровле горной выработки, причем ветви канатов как уравновешивающего каната, так и подъемного каната должны быть строго параллельны, имеется в виду - их вертикальные ветви, иначе лебедка не потянет, таким образом, в уравновешивающем канате создается разное натяжение последнего в ветвях каната как в восходящих ветвях, так и в нисходящих.A lifting device including a worm winch, mainly acting on the muscular strength of a person, a rope with a nine-fold pulley or more, which is suspended as close as possible to the center of gravity of the device, which consists of the device itself and the manipulator that needs to be lifted to the monorail at the roof of the mine and fix on the latter, characterized in that, in order to increase the reliability of the hoisting hoists, increase the reliability of lifting the manipulator and balance some of the unbalanced part of the weight of the manipulator, the ninefold pulley block is carried out with blocks, the blocks are staggered with the most parallel branches of the rope with minimal crossing of the branches of the ascending and descending ones, and in order to balance some residual unbalanced part of the weight of the manipulator, the ropes are fixed to its four corner suspension points , which is an endless rope, fastened to the ascending branches to the manipulator, the blocks of which are fixed with rod creams straight to the soil and the roof of the mine, moreover, the branches of the ropes of both the balancing rope and the hoisting rope must be strictly parallel, meaning their vertical branches, otherwise the winch will not pull, so different tension of the latter is created in the balancing rope in the branches of the rope both in ascending branches and in descending ones.

Claims

A lifting device including a worm winch, mainly acting on the muscular strength of a person, a rope with a nine-fold pulley or more, which is suspended as close as possible to the center of gravity of the device, which consists of the device itself and the manipulator that needs to be lifted to the monorail at the roof of the mine and fix on the latter, characterized in that, in order to increase the reliability of the hoisting hoists, increase the reliability of lifting the manipulator and balance some of the unbalanced part of the weight of the manipulator, the ninefold pulley block is carried out with blocks, the blocks are staggered with the most parallel branches of the rope with minimal crossing of the branches of the ascending and descending ones, and in order to balance some residual unbalanced part of the weight of the manipulator, the ropes are fixed to its four corner suspension points , which is an endless rope, fastened to the ascending branches to the manipulator, the blocks of which are fixed with rod creams straight to the soil and the roof of the mine, moreover, the branches of the ropes of both the balancing rope and the hoisting rope must be strictly parallel, meaning their vertical branches, otherwise the winch will not pull, so different tension of the latter is created in the balancing rope in the branches of the rope both in ascending branches and in descending ones.
