Abstract
Изобретение относитс к подъемным устройствам, а именно к безопасным руко ткам лебедок. Целью изобретени вл етс повышение долговечности лебедки путем повышени плавности работы руко тки. Безопасна руко тка жестко установлена на приводном валу 2 лебедки и содержит подпружиненный стопор 3, размещенный в корпусе 1 руко тки, защитный кожух 20, неподвижно соединенный с корпусом лебедки, фиксирующее колесо 7 с радиальными канавками , шаг которых равен 0,8-0,9 диаметра стопора 3, и две вилки, соединенные с колесом 7 втулкой 14, концы которых прикреплены пружинами 18 к защитному кожуху 20. При внезапном отпускании руко тки пружина 4 возвращаетс в свободное состо ние и вызывает перемещение стопора 3, который входит в одну из ближайших канавок фиксирующего колеса 7. Подвешенный груз стремитс повернуть приводной вал 2 с фиксирующим колесом 7 в сторону опускани груза, однако этому преп тствуют тормозные пружины раст жени 18, которые плавно останавливают приводной вал 2. 6 ил.The invention relates to lifting devices, namely to safe handles of winches. The aim of the invention is to increase the durability of the winch by improving the smoothness of the handle. The safety handle is rigidly mounted on the drive shaft 2 of the winch and contains a spring-loaded stopper 3 placed in the case 1 of the handle, a protective casing 20 fixedly connected to the case of the winch, fixing the wheel 7 with radial grooves whose pitch is 0.8-0.9 diameter of the stopper 3, and two forks connected to the wheel 7 by the sleeve 14, the ends of which are attached by springs 18 to the protective casing 20. When the handle is suddenly released, the spring 4 returns to its idle state and causes movement of the stopper 3, which is in one of the closest grooves of the locking wheel 7. The suspended load tends to turn the drive shaft 2 with the locking wheel 7 in the direction of lowering the load; however, this is prevented by the stretching brake springs 18, which gradually stop the drive shaft 2. 6 Il.
