Description
(54) УСТРОЙСТВО ДЛЯ ЗАЩИТЫ ОТ РАЗЛЕТА КУСКОВГ ПОРОДЫ ПРИ ВЗРЫВНЫХ РАБОТАХ(54) DEVICE FOR PROTECTION AGAINST SCALE OF DOG BREAK AT EXPLOSIVE WORKS
шпура, В верхней части т ги 4 имеетс захватное приспособление 9, выполненное , например, в виде кольц.а, дл креплени амортизатора 2. К захватнсму приспособлению 9 может крепйтьс непосредственно сеть 1.bore hole. In the upper part of the gig 4 there is a gripping device 9 made, for example, in the form of a ring, for fastening the shock absorber 2. The gripping device 1 can be attached directly to the gripping device 9.
Извлечение анкера производитс в следующем пор дке.The anchor is removed in the following order.
В отве1;4стие 10, имеквдеес в упоре 8, ввод т крюк 11, нанос т удар сверху по т ге 4, при этом штифт б переместитс вниз и отожмет упор 8 и п ту 5 от стенки шпура. Прижав рукой крюк 11 к т ге 4 вынимают анкер из шпура.In answer 1; 4, stage 10, imbods in support 8, hook 11 is inserted, a blow is struck from above on point 4, while the pin b moves down and depress stop 8 and ptu 5 from the hole wall. Pressing the hook 11 to 4 with the hand, take the anchor out of the hole.
До производства взрыва сеть 1 расстилают на поверхности грунта и по е периметру .т шпуры под анкера. Упор каждого перемещают вверх по т ге в крайнее верхнее положение и :анкер в сборе опускают в шпур. При достижении упором заданной глубины по нему нанос т удар, например, ломом или специальной оправкой в направлении стрелки Б (фиг.2). Дальнейшее прижатие к стенкам шпура упора 8 и п ты 5 происходит в результате приложени к захватно |у приспособлению 9 направленного вертикально вверх вырывающего усили .Before the explosion, the net 1 is spread on the soil surface and along its perimeter .t holes under the anchor. The stop of each is moved upwards to the extreme upper position and: the anchor assembly is lowered into the hole. When the stop reaches a predetermined depth, a blow is struck on it, for example, with a crowbar or a special mandrel in the direction of arrow B (Fig. 2). Further pressing of the stop 8 and 5 of the anvil 5 to the hole wall results from the attachment to the gripping device 9 of a vertically directed upward pulling force.
Предлагаемое устройство повышает надежность защиты от разлета кусков взрывной породы.The proposed device improves the reliability of protection against scattering of pieces of explosive rock.
