Description

Насто щее изобретение касаетс  устройства электрической установки дл  питани  матнитофугальных отбойных молотков многофазным (преимущественно трехфазным) током.The present invention relates to an electrical installation device for feeding matifofugal jackhammers with a multi-phase (mainly three-phase) current.

Согласно изобретению, дл  этой цели предлагаетс  примен ть электрический генератор с возвратно-поступательным пр молинейным перемещением индуктора вдоль статора, приводимый в движение от двигател  Посто нной скорости (например, от асинхронного электродвигател ) при помощи кривошипно-шатунного механизма.According to the invention, for this purpose, it is proposed to use an electric generator with reciprocating rectilinear movement of the inductor along the stator, driven by a constant speed motor (for example, an asynchronous electric motor) using a crank mechanism.

Применением подобного устройства достигаетс  то, что бегущее магнитное поле в магнитофугальвых молотках в течение лервой половины хода бойка перемещаетс  равноускоренно , а в течение второй половины-равнозамедленно .By using such a device, it is achieved that the traveling magnetic field in the magnet-hammer hammers during the first half of the stroke of the striker moves equally accelerated, and during the second half it is equally slow.

На чертеже изображена предлагаема  электрическа  установка, состо ща  из вала 1 приводного двигател  (например, асинхронного электродвигател ), кривошипа 2шатуна 3, и«дуктора 4 и статора 6 синхронной мащины, представл ющих собой электрический генератор, и параллелей 5.The drawing shows the proposed electrical installation, consisting of a drive motor shaft 1 (for example, an asynchronous electric motor), a crank 2 of a rod 3, and a ductor 4 and a synchronous masking stator 6, which are an electric generator, and parallels 5.

Индуктор 4 лежит на параллел х 5 и перемещаетс  над плоским статором & при помощи кривошипно-шатунного мехаиизмд 2-3,Inductor 4 lies on parallel 5 and moves above the flat stator & using a crank drive mechanism 2-3,

При перемещении индуктора 4 измен етс  частота и величина амплитуды ЭДС, индуктированной в обмотке статора генератора, в результате чего бегущее магнитное поле в магнитофугальных молотках в течение первой половины хода бойк;; перемещаетс  равноускоренно, а в течение второ-й по.ловины - равнозамедленно .When the inductor 4 is moved, the frequency and amplitude of the EMF induced in the generator stator winding changes, resulting in a running magnetic field in the magnetic hammers during the first half of the stroke; moves evenly accelerated, and during the second half of the valley - equally immediately.

Соединение магнитофугального отбойного молотка с генератором можно производить кабелем, с целые осуществлени  дистанционного управлени  с одновременным контролем цепи заземлени  молотка.The connection of the magnetofugal breaker with the generator can be made by cable, with the entire implementation of remote control with simultaneous control of the ground circuit of the hammer.

Предмет изобретени  Электрическа  установка дл  питани  магнитафугальных отбойных молотков многофазным (преимущественно трехфазным) током, отличающа с  применением электрического генератора с возвратно-поступательным пр молинейным перемещением индуктора вдоль статора при помощи кривощипно-шатунного механизма от двигател  посто нной скорости (например, от асинхронного электродвигател ), с той целью, чтобы бегущее магнитное поле в молотках в течение первой половины хода бойка перемещалось равноускоренно , а в течение второй половинь равнозамедленна,Subject of the Invention An electrical installation for feeding magnet fi nal jackhammers with a multi-phase (mainly three-phase) current, which, using an electric generator with reciprocating rectilinear linear movement of the inductor along the stator using a crank mechanism from a constant speed motor (e.g. so that the running magnetic field in the hammers during the first half of the stroke was moved equally accelerated, and during the second half Vinh ravnozamedlenna,
