Изобретение относитс к горному делу, конкретно к устройствам дл выполнени монтажа и демонтажа механизированной крепи в очистном забое.The invention relates to mining, specifically to devices for mounting and dismounting mechanized lining in a clearing face.

Известно устройство дл монтажа секций механизированной крепи, включающее балку и подъемник, выполненный в виде вращающегос домкрата, снабженного захватом со скольз щими хомутами 1.A device for mounting mechanized roof supports is known, comprising a beam and a hoist made in the form of a rotating jack provided with a catch with sliding clamps 1.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс устройство дл установки верхн ков секций механизированной крепи, включающее подъемную стрелу с домкратами управлени , захват, блоки и канаты 2.The closest to the proposed technical essence and the achieved result is a device for installing upper sections of power support, including a lifting boom with control jacks, grip, blocks and ropes 2.

Недостатком указанных известных устройств вл етс сложность соединительных элементов дл креплени верхн ков на подъемном устройстве, недостаточна надежность закреплени и значительна трудоемкость сн ти верхн ка с подъемного устройства .The disadvantage of these known devices is the complexity of the connecting elements for fastening the tops on the lifting device, the lack of reliable fastening and the considerable laboriousness of removing the top from the lifting device.

Цель изобретени - повышение производительности и безопасности выполнени работ.The purpose of the invention is to increase the productivity and safety of work.

Указанна цель достигаетс тем, что захват выполнен с гидропатроном, выдвижна часть которого снабжена пластинами с насечками дл распора в ребра жесткости верхн ка секции механизированной крепи, при этом блоки жестко соединены с захватом .This goal is achieved by the fact that the grip is made with a hydraulic cartridge, the sliding part of which is equipped with plates with notches for expansion into the stiffeners of the upper section of the mechanized support, while the blocks are rigidly connected to the grip.

На фиг. 1 показано устройство в монтажной камере, вид сбоку; на фиг. 2 - блок захвата с гидропатроном, вид сбоку; на фиг. 3 - вид А на фиг. 2; на фиг. 4 - вид Б на фиг. 2.FIG. 1 shows the device in the mounting chamber, side view; in fig. 2 - gripping unit with hydraulic cartridge, side view; in fig. 3 is a view A of FIG. 2; in fig. 4 is a view B in FIG. 2

Устройство дл монтажа секций механизированной крепи включает подъемную A device for mounting mechanized lining sections includes lifting

Claims

10 boom 1, jack 2 controlling boom 1 and jack 3 controlling gripper 4, which is hinged at the end of the boom, gripper block 5 and ropes 6. Gripper 4 consists of hydraulic cartridge 7 located in weld 5 of construction 8. Gripper blocks 5 are connected to axis 9 with pins 10. From hydraulic cartridge 7, conclusion 11 was made to connect the hose to the hydraulic system. A strap 13 is welded to the stem of the hydrop cartridge, having a notch to increase friction when coupling with stiffeners 14 of the top 15. The device 6 is fixed at one end to the gripping blocks and the other to the traverse 16 of the gripping control 3. The brackets 17 mounted between the blocks 5 are designed to mount the device on the boom of the actuator. The device works as follows. Before installation, the grip 4 is lowered to the top 15 of the lining section lying on the ground. In this case, the stem of the jack 3 of the control is extended, and the rope 6 is wound on the block 5 of the grip. The sliding part 12 of the hydraulic cartridge 7 is extended and braced into the stiffening ribs 14 of the top 15. When the boom is raised, 1 jack stem 3 is pulled in, and the rope 6 wound on the gripper blocks 5 moves. the top 15 fixed on it. The diameter of block 5 is chosen based on the condition that half the circumference of the block is equal to the stroke of the piston 3. At the same time, with the fully shortened jack 3, block 5 is rotated 180 °, i.e. fixed on the hydraulic top to the side of the roof. After pririzhi top girders are attached to the roof to it. The advantage of the proposed device is fast and reliable replenishment of the top on the lifting boom, safety of operations, reduction of labor intensity. Apparatus of the Invention A device for installing overhead mechanized support sections, including a lifting boom with control jacks, a catch, blocks and ropes, characterized in that, in order to increase productivity and safety of the work, the catch has a hydraulic cartridge, the sliding part of which is equipped with notches in the stiffeners of the upper section of the mechanized support, while the blocks are rigidly connected with the grip.
