(54) ВРЕМЕННАЯ НАДУВНАЯ ПЕРЕМЫЧКА ДЛЯ ГОРНЫХ ВЬ РАБОТОК(54) TEMPORARY INFLATABLE REMOVAL FOR MOUNTAIN WORKERS

Изобретение относитс к горной промышленности и предназначено дл временной установки перемычки в горных выработках при распределении воздуха или в аварийных случа х.The invention relates to the mining industry and is intended for the temporary installation of lintels in mine workings during air distribution or in emergency situations.

Известна временна шахтна перемычка, включающа соединенные между собой резиновые подушки 1.A temporary mine bridge is known, including interconnected rubber pads 1.

Недостаток данной надувной перемычки заключаетс в плохом прилегании ее к боковым породам вьфаботки.The disadvantage of this inflatable jumper lies in its poor fit to the side rocks.

Известна также временна надувна перемычка дл горных выработок, включающа каркас, состо щий из эластичных надувных секций, перего родку, злементы крепле ш и клапаны 2.Also known is a temporary inflatable jumper for mine workings, comprising a skeleton consisting of elastic inflatable sections, a partition, fasteners and valves 2.

Недостаток данной перемычки - больша затрата времени, необходимого на ее установку, и утечки воздуха через перемычку.The disadvantage of this jumper is the large amount of time it takes to install it and air leakage through the jumper.

Цель изобретени заключаетс в сокращении времени на установку перемычки и уменьшении утечки воздуха через нее.The purpose of the invention is to reduce the time to install the jumper and reduce air leakage through it.

Указанна цель достигаетс тем, что каркас перемычки выполнен в виде двух концентрически расположенных секций, соединенных посредством перегородки, причем перемычка снабжена герметизированным лазом и редукционным клапаном, установ ленными на перегородке, соедин ющей внутреннюю и наружную секции, а злементы креплени расположены на внутренней секции.This goal is achieved in that the jumper frame is made in the form of two concentrically located sections connected by a partition wall, the jumper is provided with a pressurized hole and a pressure reducing valve mounted on the partition connecting the inner and outer sections, and fasteners are located on the inner section.

На фиг. 1 показана перемычка, разрез; на фиг. 2 - сечение А-А фиг. 1.FIG. 1 shows a jumper, a cut; in fig. 2 is a section A-A of FIG. one.

Перемьтчка состоит из концентрически расположенных секций I и 2 с перегородкой 3, в которой расположен редукционный клапан 4. Секции снабжены защитной оболочкой 5 и перегородкой 6, вьшолненными из износоустойчивого теплоизол ционного материала. Перегородка вьшолнена с герметизированным лазом 7. Внутренн секци снабжена прив зочными ремн ми 8, штуцером с краном 9 дл заполнени ее воздухом и предохранительным клапаном 10. Внешн секци камеры снабжена запорным краном 11, который необходим дл демонтажа перемычки.The part consists of concentrically disposed sections I and 2 with partition 3, in which reduction valve 4 is located. The sections are equipped with a protective sheath 5 and partition 6, filled with durable heat insulating material. The partition is made with a sealed manhole 7. The inner section is provided with attachment belts 8, a fitting with a tap 9 for filling it with air and a safety valve 10. The outer section of the chamber is equipped with a shut-off valve 11, which is necessary for dismantling the lintel.

Монтаж временной надувной перемычки производитс следующим образом.The installation of a temporary inflatable jumper is as follows.

Claims

The compressed air is connected to the jumper through a fitting with a tap 9. Under the pressure of the air, the inner section expands into the contour of the output section. Upon further pumping, the reduction valve triggers, after which the outer section spreads out to fill the irregularities of the production section contour. When the preamble is maximized, a safety valve is triggered, after which the intake air system is turned off. The installed jumper is fastened with tied belts to tcpemi workings. The jumper is dismantled by opening both the inner and outer securing valves. The installation of a more rigid inner section creates a preliminary compaction of the surface of the production section and significantly reduces the size of the gaps on its unevenness. At the same time, the section is a support for a more elastic outer section, finally eliminating these gaps when it is spaced. Since air is only pumped into ring-shaped sections around the perimeter of production, its total consumption is significantly reduced. The jumper is securely fastened in the mine due to tight belts, which increases its stability. The presence of the manhole allows emergency work on both sides of the jumper, which simplifies emergency work. The invention is a temporary inflatable jumper for mine workings, including a frame consisting of elastic inflatable sections, a partition, fasteners and valves, characterized in that, in order to reduce the time for its installation and to reduce air leakage through the jumper, the frame is complete two concentrically arranged sections connected by means of a partition, the jumper being provided with a sealed manhole and a reducing valve mounted on the partition connecting the inner and outer sections and, and fasteners are located on the inner section.
