Description
Предметом изобретени вл етс домкрат, приводимый в действие жидкой рабочей средой, подаваемой при помощи пневмо-гидравлического насоса.The subject of the invention is a jack driven by a liquid working medium supplied by a pneumatic-hydraulic pump.
Домкраты, у которых насос выполнен в виде питаемого сжатым воздухом пневматического двигател , сообщающего поступательное движение соединенному с его поршнем плунжеру гидравлического насоса , известны.Jacks, in which the pump is designed as a pneumatic engine powered by compressed air, which communicates the translational movement of the plunger of a hydraulic pump connected to its piston, are known.
Предлагаемый домкрат выполнен более компактно, что обеспечивает возможность его применени в неудобных дл работы местах, например под вагоном, паровозом и т. п.The proposed jack is made more compact, which makes it possible to use it in places that are inconvenient for work, for example, under a carriage, a locomotive, etc.
Па фиг. 1 и 2 изображен домкрат в нерабочем и рабочем положении в разрезе.Pa figs. 1 and 2 shows the jack in the non-working and working position in the section.
Плунжер 1 подъемно-опускного цилиндра 2 гидравлического домкрата неподвижно смонтирован с соосным с ним цилиндром 4 гидравлического насоса на крышке 5 пневматического двигател 6. Плунжер 3 насоса жестко соединен с поршнем 7 пневматического двигател , наход щимс под действием пружины S, сообщающей ему холостой- ход. Посредством канала 9 с обратным клапаном 10 пространство над плунжером насоса сообщаетс с пространством над плунжером домкрата.The plunger 1 of the lifting and lowering cylinder 2 of the hydraulic jack is fixedly mounted with the cylinder 4 of the hydraulic pump coaxial with it on the cover 5 of the pneumatic engine 6. The plunger 3 of the pump is rigidly connected to the piston 7 of the pneumatic engine, which is under idling. Through channel 9 with a check valve 10, the space above the pump plunger is in communication with the space above the ram plunger.
При подаче жидкости в пространство над плунжером / домкрата его цилиндр 2 поднимаетс и производит ра|боту. Дл опускани цилиндра 2 жидкость из него выпускаетс в расположенный р дом резервуар по каналу в стенке нлунжера / через управл емый вручную запорный орган.When a fluid is introduced into the space above the plunger / jack, its cylinder 2 rises and produces work. To lower the cylinder 2, liquid is discharged from it into a reservoir located next to it through a channel in the wall of the reservoir / through a manually operated shut-off member.
