Abstract

Изобретение относитс к горному и строительному оборудованию и м.б, использовано дл извлечени гидроигл, буровых штанг и обсадных труб из грунта. Цель - снижение материальных затрат на извлечение. Устр-во дл извлечени гидроигл включает узел захвата гидроиглы в виде трех собачек 1, шарнирно закрепленных одними концами на верхней поверхности подвижной платформы (П) 2 и расположенных одна относительно другой под углом 120. Подвижна П 2 имеет два отверсти с винтовой резьбой, в которых вставлены вертикальные винтовые стержни (ВС) 3, закрепленные через подшипники с верхней неподвижной П и опорной П. В нижней части ВС 3 жестко закреплены шки- чвы, приводимые во вращение ремн ми 7 с помощью редуктора 8 и электродвигател (ЭД) 9. На верхней неподвижной П и опорной П установлены концевыр переключатели . При включении ЭД 9 через редуктор 8 приводные ремни 7 и шкивы вращают ВС 3. За счет резьбового соединени отверстий подвижной П 2 и ВС 3 происходит вертикальное перемещение П 2 вверх. Посредством большого трени между собачками 1 и гидроиглой движени последней происходит одновременно с подвижной П 2. При достижении П 2 крайнего верхнего положени срабатывает концевой переключатель, расположенный на верхней П, при этом происходит реверс ЭД 9. Цикл повтор етс автоматически до полного извлечени гидроиглы. 4 ил. А-А IThe invention relates to mining and construction equipment, and may be used to extract hydraulic needles, drill rods and casing from the ground. The goal is to reduce material costs for extraction. The device for extracting the hydro-needle includes a pick-up unit of the hydro-needle in the form of three dogs 1, hinged at one end on the upper surface of the movable platform (P) 2 and located one relative to the other at an angle of 120. The mobile P 2 has two screw holes with vertical screw rods (BC) 3 are inserted, fixed through bearings with the upper fixed P and supporting P. In the lower part of BC 3, the pulleys are set, driven by the belts 7 with the help of a gear 8 and an electric motor (ED) 9. On the top P fixed and the reference set P kontsevyr switches. When the ED 9 is turned on through the reducer 8, the drive belts 7 and the pulleys rotate the sun 3. Due to the threaded connection of the openings of the movable P 2 and Sun 3, the P 2 moves vertically upwards. By means of a large friction between the dogs 1 and the hydro-needle, the movement of the latter occurs simultaneously with the mobile P 2. When the P 2 reaches its extreme upper position, the end switch located on the upper P operates, and the ED 9 reverses automatically. The cycle repeats automatically until the hydro needle is completely removed. 4 il. A-A I

Claims

Claim

A device for extracting a hydroneedle, including a support platform, an engine for lifting a hydroneedle with a gearbox and a node for capturing a hydroneedle, characterized in that, p. In order to reduce the material costs of extraction, it is equipped with two rods vertically mounted on the support platform, made with screw threads along their entire length and with the possibility of rotation of the rods, additional upper fixed platform mounted on the free ends of the screw rods, and an intermediate platform made in it holes for the rods with screw threads and installed with the possibility of movement along these rods, and limit switches, one of which is mounted on the bottom th surface of the upper platform, and the other on the upper surface of the support platform with the possibility of contacting with the intermediate platform, while 'all platforms are made with' cutouts located one below the other, and the gripping unit is mounted on the intermediate platform along the edges of the cutout and is made in the form three locking dogs, pivotally fixed at one end on the upper surface of the platform and located one relative to the other under-angle 120 ^.
