Abstract
The utility model provides a reciprocating jacking device. A reciprocating air-actuated device comprising a hydraulic oil cylinder, a cylinder, a piston, an air duct, and an air regulating valve is connected with a hydraulic jack; the reciprocating air-actuated oil pressure is combined with a novel jacking device; the pipe joint of the hydraulic oil cylinder of the reciprocating air-actuated device is connected with the lifting oil cylinder interface of the jack, and the cylinder body of the hydraulic oil cylinder is connected with the cylinder body bottom of the cylinder. The piston is a T-shaped piston arranged inside of the cylinder and the hydraulic oil cylinder, and the piston body of the upper part of the piston is connected inside of the cylinder by movable matching, and the column of the piston is connected inside of the hydraulic oil cylinder by movable matching; the column body of piston is sheathed with a return spring. The upper air vessel of the cylinder and the lower air vessel of the cylinder are communicated with an air regulating valve which is connected with the air bottle of an air pump. The utility model has novel structure, novel design, labor saving and convenient use, and the utility model is a novel lifting machine suitable to vehicles, mechanical maintenance service, manufacturing etc.
Description
Technical field
The utility model designs a kind of elevator machinery, especially a kind of instrument of lifting object of pneumatic, oil pressure.
Background technology
Among known technology, existing jacking device also is generally manual hydraulic type jack for " jack ", mainly by packing liquid oil and be equiped with check valve and operating handle is formed in the hydraulic piston tube into, and its effort of taking a lot of work, it is big to operate labour intensity; Also have plenty of the electric oil pressure jack, have the driven by motor hydraulic piston to carry out the jacking article, but its structure is complicated, use inconvenience.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of novel structure, saves labor, new-type jacking device easy to use.
The technical scheme in the invention for solving the technical problem is: adopt the reciprocating type air-operated apparatus of being made up of hydraulic ram, cylinder, piston, ventilation flue and Air-regulating valves to be connected oil jack, the combined jacking device of reciprocating type pneumatic oil pressure that consists of.The adaptor union of the hydraulic ram of reciprocating type air-operated apparatus connects the external tapping of jack, hydraulic ram is connected in the cylinder base of cylinder, the piston load is in cylinder and hydraulic ram, its top cock body running-fit is connected in the cylinder, bottom stick harness running-fit is connected in the hydraulic ram, and on the stick harness body of piston, be set with pull back spring, be equiped with upper and lower ventilation flue on the cylinder and be communicated with the Air-regulating valves that connects the air pump gas cylinder.During use, Air-regulating valves is connected with the air pump or the air bottle of air compressor, and the jacking dish of jack is positioned over the object appropriate location that needs jacking, open the gas cylinder switch, pressurized air has Air-regulating valves A mouth to enter, the last ventilation flue who is connected by the B mouth enters into from cylinder head and promotes piston in the cylinder and move down, the stick harness of piston enters into the hydraulic oil in the hydraulic ram in the jacking cylinder of jack by the check valve of adaptor union through jack, just the jacking post that promotes jacking cylinder shifts, and the lower chamber of cylinder is communicated with the exhaust E mouth exhaust of Air-regulating valves by downtake simultaneously; The plunger of pulling control Air-regulating valves is transformed to the downtake that is connected by the D mouth that communicates with the A mouth and enters into from cylinder bottom and promote piston stroking upward in the cylinder, piston passes through jack check valve inhalant liquid compressing cylinder to hydraulic oil under the effect of pull back spring, the upper chamber of cylinder is communicated with the exhaust C mouth exhaust of Air-regulating valves by last ventilation flue simultaneously, like this, just finished a working cycle.
Reciprocating type jacking device of the present utility model is applicable to the maintenance industry, manufacture of self-propelled vehicle and various machineries etc., because mostly these industries are to be equipped with by air pump or air compressor, so connect easy to use.
Because technique scheme has been adopted in the utility model design, show that it has novel structure through test for several times is on probation, advantage such as design innovation saves labor, and is safe and convenient to use is a kind of later-model machinery that hoists.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model embodiment concrete structure figure.
Fig. 2 is that the B-B of Fig. 1 is to view.
Reference numeral: 1 Air-regulating valves, 2 downtakes, ventilation flue on 3,4 cylinders, 5 springs, 6 pistons, 7 hydraulic rams, 8 adaptor unions, 9 jacks, 10 jack check valves, 11 cylinder body binding posts, 12 wiring are struck the post, 13 insulating mats.
The specific embodiment
Embodiment as shown in Figure 1, the utility model adopt the reciprocating type air-operated apparatus of being made up of hydraulic ram 7, cylinder 4, piston 6, last ventilation flue 3, downtake 2 and Air-regulating valves 1, and reciprocating type air-operated apparatus connects oil jack 9 and forms.The cylinder body inner bottom part of the cylinder 4 of reciprocating type air-operated apparatus is connecting hydraulic ram 7, the adaptor union 8 of hydraulic ram 7 connects the external tapping of jack 9, piston 6 is that the load of T type piston is in cylinder and hydraulic ram, its top cock body running-fit is connected in the cylinder 4, bottom stick harness running-fit is connected in the hydraulic ram 7, and on the stick harness body of piston 6, be set with pull back spring 5, and be communicated with the Air-regulating valves 1 that is connected the air pump gas cylinder with downtake 2 being fitted with ventilation flue 3 on the cylinder 4.Air-regulating valves 1 in the utility model is the Air-regulating valves of interior dynamic formula Air-regulating valves or other type.
Referring to accompanying drawing 1, Fig. 2 embodiment, the inner bottom part of cylinder 4 cylinder bodies of the present utility model also is equiped with the wiring of cylinder body insulation bonded assembly and strikes the post 12, wiring strike the post 12 and cylinder 4 cylinder bodies between be fitted with insulating mat 13, and on cylinder 4 cylinder bodies, be fitted with cylinder body binding post 11.During use, with wiring strike the post 12 and cylinder body binding post 11 be electrically connected respectively control Air-regulating valves 1 slug relay.Wiring in piston 6 running-fits and the cylinder block is struck the post and 12 is connected, and its effect is the after bottom center of setting in piston arrives, touches and links the wiring 12 slug relay's conducting work that connected with binding post 11 of striking the post, and just makes piston answer.
