Description
Известны лебедки, предназначенные по преимуществу дл подвески комба 1нов или врубовых машин при выемке угл , приводимые в движение Эотектродвигателем через коробку скоростей, содержаш,ую шестерню , включаемую при иомош,и поворотного рычага, управл емого соленоидом . Однако в таких лебедках скорости переключаютс вручную.The winches, which are mainly used for the suspension of a combo of a new or a cutting machine during coal excavation, driven by an electric motor through a gearbox, are known, containing the gear that is activated by the motor and a rotary lever controlled by the solenoid. However, in such winches, the speeds are switched manually.
Дл осуш,ествлени дистанционного реверса электродвигател одновременно с включением шестерни предлагаетс лебедка, в которой сердечник соленоида выполнен из двух еоосных частей. Одна из I-THX частей неподвижна, а друга , сопр женна с поворотным рычагом, перемещаетс навстречу первой, причем обе части включены в цепь управлени электродвигателем так, что при их соприкосновении замыкаетс цепь реверса электродвигател .To dry, remotely reverse the electric motor and simultaneously turn on the gear, a winch is offered, in which the solenoid core is made of two axle parts. One of the I-THX parts is stationary, and the other, coupled to the pivot arm, moves towards the first, with both parts included in the motor control circuit so that when they are in contact, the reverse motor circuit is closed.
На чертеже изображена схема лебедки.The drawing shows the scheme of the winch.
Лебедка состоит из барабана 1, коробки скоростей 2 и приводитс 1 движение от реверсивного электродвигател 3.The winch consists of a drum 1, a gearbox 2 and 1 movement from a reverse motor 3 is driven.
Во врем рабочего хода комбайна или врубовой машины крут щий момент от электродвигател 3 передаетс через зубчатые колеса 4 5 и фрикционную муфту 6 на вал 7, а с него через черв чную передачу 8 и зубчатую передачу 9 на барабан 1. Зубчатое колесо 10, свободно сид щее на валу //, не вращаетс , так как собачка 12, св занна с колесом 10, свободно обегает храповое колесо 13, вращающеес вместе с валом 11.During the working stroke of the combine or the cutting machine, the torque from the electric motor 3 is transmitted through the gears 4 5 and the friction clutch 6 to the shaft 7, and from it through the worm gear 8 and the gear gear 9 to the drum 1. Gear The shaft on the shaft // does not rotate, since the pawl 12, connected to the wheel 10, runs freely around the ratchet wheel 13, which rotates together with the shaft 11.
При включении обратного хода ток поступает в обмотку 14 соленоида 15, подвижна часть 16 сердечника которого начинает перемещатьс навстречу неподвижной части П. При этом зубчатое колесо 4, св занное через поворотный рычаг 18 с подвижной частью 16 сердечника соWhen reverse motion is switched on, the current enters the winding 14 of the solenoid 15, the movable part 16 of the core of which begins to move towards the stationary part P. At the same time, the gear wheel 4 connected through the rotary lever 18 to the movable part 16 of the core with
