Description

11редлагаелюе изобретение относ тс  к устройствам, состо щим из грейфера, на раме которого смонтирован тельфер. Известны грейферы, у которых открывание и закрывание ковшей осуществл ютс  посредством полиспаста . В предлагаемо,, согласно изобретению, грейфере, с целью придани  ему компактности и уменьшени  его высоты, неиодвижные блоки полиспаста смонтированы соосно с барабаном тельфера. На фиг. 1 и 2 изображены две вертикальные проекции грейфера, на фиг. 3-вертикальный разрез тельфера . Сущность предложени  заключаетс  в следующем. К головке 2 грейфера прикреплен блок тельфера, в котором соосно смонтированы мотор 1, барабан 7 и неподвижные блоки 9 полиспаста , нижние подвижные блоки 8 которого укреплены на траверсе 4. На той же траверсе 4 поворотно укреплены ковши 5 и 6, шарнирно сочлененные с т гами 3, подвешенными к головке 2 грейфера и сопр женными между собой посредством системы звеньев 10. Открывание и закрывание ковшей осуществл етс  при помощи барабана 7 посредством полиспаста и т г 3. П р е i м е п 3 о б р е т е н н   Грейфер с применением монтированного на его раме тельфера, осуществл ющего закрывание ковщей и св занного с последними посредством полиспаста, отличающийс   тем, что неподвижные блоки 9 полиспаста смонтированы соосно с барабаном 7 тельфера.11, the present invention relates to a device consisting of a grab, on the frame of which a hoist is mounted. Grabs are known in which the opening and closing of the buckets are carried out by means of a chain hoist. In the proposed, according to the invention, the grapple, in order to give it compactness and reduce its height, the non-sliding blocks of the chain hoist are mounted coaxially with the hoist drum. FIG. 1 and 2 show two vertical projections of the grapple; FIG. 3-vertical section of the hoist. The essence of the proposal is as follows. A telpher block is attached to the head 2 of the grapple, in which the motor 1, the drum 7 and the fixed blocks 9 of the polyspast are coaxially mounted, the lower movable blocks 8 of which are fixed on the traverse 4. On the same traverse 4, the buckets 5 and 6 are hingedly articulated 3, suspended from the head 2 of the grapple and mated to each other by means of a system of links 10. The opening and closing of the buckets is carried out with the help of a drum 7 by means of a chain hoist and t g 3. Reme n 3 o barre n Grapple with mounted on its frame a blade that closes the forgers and is connected to the latter by means of a tackle, characterized in that the fixed blocks 9 of the tackle are mounted coaxially with the hoist 7.
