Изобретение относитс к подъемно-транспортным устройствам, используе.мым дл ловителей лифтов и подъемников.FIELD OF THE INVENTION The invention relates to lifting and transporting devices used for elevator and hoist catchers.
По основному авт. св. № 479712 известен ловитель парашюта с тор.мозными канатами дл улавливани и остановки шахтной клети, включаюш.ий центральную т гу, соедин нующую ловитель с подъемным канатом , корпус с траверсой, два шарнира которой соединены посредством рычагов с клиновыми зажимами, причем траверса соединена с т гой посредством дополнительного шарнира, установленного соосно с шарниром штока 1.According to the main author. St. No. 479712 is known for a parachute safety device with toroidal ropes for catching and stopping the mine cage, including a central pull, a connecting safety device with a lifting cable, a body with a cross-arm, two hinges of which are connected by means of levers with wedge clamps, and the cross-arm is connected to t goy through an additional hinge mounted coaxially with the hinge rod 1.
Недостатком ловител вл етс передача от тормозныхканатов на клеть при срабатывании парашюта больших стопор ших усилий, вызываюших значительные инерционные нагрузки на клеть, которые могут нривести к травмированию наход ши.хс в клети людей.The disadvantage of the catcher is the transfer from the brake kits to the cage when the parachute is triggered by large stopping forces, which cause significant inertial loads on the cage, which can lead to injury to people in the cage.
Цель изобретени - повышение надежности путем ограничени инерционности сил.The purpose of the invention is to increase reliability by limiting the inertia of forces.
Дл достижени этой цели шток выполнен из двух частей, между которыми шарнирно закреплен гидроцилиндр.To achieve this goal, the rod is made of two parts, between which the hydraulic cylinder is hinged.
На фиг. 1 изображен ловитель, общий Еид; на фиг. 2 - гидросхе.ма цилиндра. Ловитель парашюта состоит «з корпуса 1, на котором шарнирно закреплены рычаги 2, соединенные траверсой 3, к траверсе 3 шарнирно прикреплена центральна т га 4 и шток 5. Клинь 6 подвижно св заны с рычагами 2 и снабжены предохранительны, устройством 7, гидроцилиндром 9 со штоком 10 гидроцилиндра. Траверса 3 с помошью шарниров 11 соедин етс с центральнойFIG. 1 shows the catcher, a common Eid; in fig. 2 - cylinder hydraulic circuit. The parachute safety device consists of the case 1, on which the arms 2, connected by traverse 3, are pivotally fixed, to the traverse 3, the central rod 4 and the rod 5 are pivotally attached. The wedge 6 is movably connected to the arms 2 and equipped with safety devices 7, a hydraulic cylinder 9 rod 10 hydraulic cylinders. Traverse 3 is connected to central hubs 11 by means of hinges.
0 т гой 4 и штоком 10 гидроцилиндра, а шарнира .ми 12 - с рычажной системой. Шарнир 13 соедин ет шток 5 и корпус гидроцилиндра 9. Поршнева полость цилиндра сообш,аетс с ко.мпенсационным бачком 14. Штокова и поршнева полости гидроци5 линдра соединены между собой магистралью 15 с обратным клапаном 16 и магистралью 17 с последовательно расположенными предохранительным клапано.м 18 и дросселем 19. Ловитель взаимодействует с канатом 20, имеющим втулку 21.0 tons 4 and a rod of 10 hydraulic cylinders, and a hinge. 12 them - with lever system. The hinge 13 connects the rod 5 and the hydraulic cylinder body 9. The piston cylinder cavity communicates with the cushion casing 14. The rod and piston cavity of the hydraulic cylinder are connected to each other by a main 15 with a check valve 16 and a main line 17 with successive safety valves 18 and choke 19. The safety device interacts with the rope 20, having a sleeve 21.
При обрыве головного каната или прицепного устройства пружина 8 разжимаетс , т га 4, траверса 3, гидроцилиндр 9 и шток 5 опускаютс , разворачива рычаги 2 вокругWhen the head rope or the hitch is broken, the spring 8 expands, th ha 4, the yoke 3, the hydraulic cylinder 9 and the stem 5 lower, turning the levers 2 around
