Изобретение касаетс креплени забоев угольных шахт секци ми механизированной крепи.The invention relates to securing the bottom of coal mines with mechanized support sections.

Известна -секци шахтн механизирован ной крепи, включающа посадочную и забойную части, св занные между собой силовык домкратом и имеющие основани , на которые (отираютс гидростойки, нбСуЩие верхн ки.The known section of mine shafts, including landing and downhole parts, interconnected with a power jack and having bases on which (hydraulic racks are opened, are equipped with a sump.

Однако така секци не может быть иопользована в пластах малой мс цности, так как силовые дс икраты, св зьгеающие забойную и посадочную части, загромождают про ход дл обслуживающего персонала и не обеспечивают синхронной передвижки оснон. вани и верхн ка забойной части с подпс ром .However, such a section cannot be used in seams of small masses, since the power supply connectors of the downhole and landing parts block the passage for the operating personnel and do not provide a synchronous movement of the core. vani and top of the downhole part with subs.

Цель изобретени - обеспечить синхрон- ную передвижку рснсжани и верхн ка аа бойной части секции с подаорс в пластах малой мсипности.The purpose of the invention is to provide a synchronous movement of the hinge and upper aa of the combat part of the section with the flow in the formations of small muddy.

Это достигаетс тем, что в основание и верхн к посадочной части секции вмонти рованы барабаны, сблокированные между собой телесктической балкой, причем один . из барабанов соединен гибким элементом с This is achieved by the fact that drums interlocked with each other by a telescopic beam are mounted in the base and upper to the landing part of the section, and one. of the drums connected by a flexible element with

силсюым домкратсни, а другой - с забойной частою секции.to a strong jack and the other with a downhole section.

На фиг. 1 изображена предлагаема сек ци , общий вид; на фиг. 2 верхн ки забойной и посадочной частей секции.FIG. 1 shows the proposed section, general view; in fig. 2 top ki downhole and landing sections.

Описываема секци включает посадоч ную 1 и забойную 2 части, св занные между собой силовым домкратсжд 3 и имеющие , основани 4 и 5, на которые спираютс гидростойки 6 и 7, несущие верхн ки 8 и 9.The described section includes a landing 1 and a downhole 2 parts, interconnected by a power jack 3 and having bases 4 and 5, onto which hydroresistances 6 and 7 are supported, carrying the tops 8 and 9.

В основание 5 и верхн к 9 посадочной части секции вмонтированы барабаны 10 и 11, сблсжир(жанные между собой телеск(ши« ческой балкой 12. Барабан 10 соединен гибким элементсжл 13 „с силовым домкратом 3, а барабан 11 гибким элементом 14 с забойной частью 2 секции. ; Секци работает следующим образсы.Reels 10 and 11 are mounted in the base 5 and top to 9 of the landing part of the section (chopped between each other telescope (shear beam 12. The drum 10 is connected by a flexible element 13 "to the power jack 3, and the drum 11 by a flexible element 14 with a downhole part Section 2; Section operates as follows.

Claims

As the bottom hole section moves, the lower drum is rotated through the flexible element, which is interlocked with the upper drum by the telescopic beam and also begins to rotate. Moreover, the flexible elements of the Nama. tans so that from one drum reel with, and. on the other, they are wound up. When the flexible element is wound on the upper drum, spring packages 15 are put forward synchronously with the destabilization of the bore part of the section.
