Abstract
The utility model relates to a double-cylinder parallel oil cylinder, which mainly consists of a main cylinder and an assistant cylinder, and is characterized in that the bodies of the main cylinder and the assistant cylinder are superposed and fixed in parallel, and piston rods of the two cylinders stretch out reversely; oil inlets and oil outlets of the main cylinder and the assistant cylinder are mutually communicated, two independent flow channels are arranged in the piston rod of the main cylinder, and the two independent flow channels are respectively communicated with a cavity with a rod and a cavity without a rod of the main cylinder. The utility model has the advantages that the propulsion stroke of the double-cylinder parallel oil cylinder is determined by the superposition of the stretching lengths of the piston rods of the main cylinder and the assistant cylinder, and compared with the stroke of an ordinary hydraulic cylinder, the stroke of the double-cylinder parallel oil cylinder is increased by about one time on the basis of not increasing entire length. Built-in hydraulic oil flow channels are adopted in the main cylinder and the assistant cylinder for oil inlet and oil outlet, so the installation of hydraulic pipelines is reduced, and space is saved, which is conductive to the simplifying, miniaturizing and integrating development of equipment.
Description
Technical field
The utility model relates to a kind of hydraulic jack, big and twin-tub compact structure the oil cylinder in parallel of particularly a kind of stroke.
Background technique
Hydraulic jack is a most important executive component in the hydraulic system, and it is hydraulic pressure energy converter tool energy, and matches with various driving mechanisms, finishes various mechanical motion.That oil hydraulic cylinder has is simple in structure, ouput force is big, stable and reliable for performance, characteristics such as working service makes things convenient for, have wide range of applications.Along with the raising of mechanization degree, structure, quality and the volume of hydraulic jack are also had higher requirement.
Traditional hydraulic jack mainly comprises cylinder body and be located at piston rod in the cylinder piston chamber, and it advances length and cylinder piston cavity length to be equal to substantially, when the length of needs propelling is longer, then needs the cylinder body of respective length to realize, and is bulky.And can't realize by the lengthening cylinder body by the restriction of installing space, for example for solving the underground stereo garage that the parking difficulty problem now is in development, its translation mechanism of fetching and delivering platform is used for propelling vehicle and pushes parking position from fetching and delivering platform, or is taken back by parking position and to fetch and deliver platform.Fetch and deliver the platform advance distance more than 5 meters, the stroke of its required oil cylinder is more than 5 meters, prevent that vehicle from moving up and down or move forward and backward clamping, the jacking mechanism that causes the damage of scratching when rotating in the garage and fetch and deliver also need install in the platform, installing space is very restricted, and causes and fetches and delivers the shortcoming that platform by volume is huge, operating cost is high.
Summary of the invention
The technical problems to be solved in the utility model provides big and twin-tub compact structure the oil cylinder in parallel of a kind of stroke.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of twin-tub oil cylinder in parallel, mainly to form by master cylinder and secondary cylinder, and its innovative point is: the stack in parallel with the cylinder body of secondary cylinder of described master cylinder is fixing, and both piston rods oppositely stretch out; Being interconnected into and out of hydraulic fluid port of described master cylinder and secondary cylinder has two independent runners in the piston rod of master cylinder, described two independent runners are communicated with the rod chamber and the rodless cavity of master cylinder respectively.
Further, the end of described main cylinder piston-rod is equipped with bar head earrings, this bar head earrings be provided be communicated with main cylinder piston-rod two independent runners respectively into and out of hydraulic fluid port.
Further, the carriage that slides or roll and cooperate with other assemblies when being used for this twin-tub oil cylinder in parallel and being subjected to displacement is installed on the described twin-tub of forming by master cylinder and the secondary cylinder oil cylinder in parallel.
Further, be provided with chamfering on described carriage, this chamfering is positioned on the movement direction of twin-tub oil cylinder in parallel.
Advantage of the present utility model is: the propelling stroke of this twin-tub oil cylinder in parallel is by the piston rod extrusion stack decision of major and minor cylinder, about comparing normal hydraulic oil cylinder stroke on the basis that does not increase entire length and doubling.And major and minor cylinder adopts built-in hydraulic oil runner to carry out into and out of oil, has reduced the installation of hydraulic pipe line, has saved the space, helps equipment to simplifying, miniaturization and integrated direction development.
Description of drawings

Fig. 2 is the utility model twin-tub oil cylinder sectional view in parallel.
Fig. 3 is installed in the use schematic representation on the platform fetched and delivered of underground parking garage for the utility model twin-tub oil cylinder in parallel.
Embodiment
As shown in the figure, the utility model relates to big and twin-tub compact structure the oil cylinder in parallel of a kind of stroke, and it mainly is made up of master cylinder 1 and secondary cylinder 2, and this master cylinder 1 is fixing by flange stack in parallel with the cylinder body of secondary cylinder 2, and both piston rod 1a, 2a oppositely stretch out.
Master cylinder 1 is interconnected into and out of hydraulic fluid port with secondary cylinder 2, and concrete: the rod chamber of major and minor cylinder 1,2 is interconnected, and rodless cavity is interconnected.Have two independent runners 3,4 in the piston rod 1a of master cylinder 1, this two independent runner 3,4 is communicated with the rod chamber and the rodless cavity of master cylinder 1 respectively.Bar head earrings 5 is installed in the end of main cylinder piston-rod 1a, this bar head earrings 5 be provided be communicated with main cylinder piston-rod 1a two independent runners 3,4 respectively into and out of hydraulic fluid port 5a, 5b.
Bolt has carriage 6 on twin-tub oil cylinder in parallel, and sliding or roll with other assemblies when this carriage is used for this twin-tub oil cylinder in parallel and is subjected to displacement cooperates.Carriage 6 is provided with chamfering, and this chamfering is positioned on the movement direction of twin-tub oil cylinder in parallel.
Specifically be installed to and fetch and deliver on the platform when realizing fetching and delivering plate 7 front and back translations, as shown in Figure 3, twin-tub oil cylinder in parallel places on the base plate 8 of fetching and delivering platform, on the base plate 8 roller is installed, supporting plate 6 drops on the roller of base plate 8, cooperate with its rolling, the piston rod 1a of master cylinder 1 is fixedlyed connected with base plate 8, and the piston cylinder 1b of secondary cylinder 2 with fetch and deliver plate 7 and fixedly connected.Hydraulic oil enters the rodless cavity of master cylinder 1 and secondary cylinder 2 by bar head earrings 5 into and out of hydraulic fluid port along the runner of piston rod 1a, make the cylinder body slip of master cylinder 1 move forward, secondary cylinder 2 piston rod 2a reach realize the translation of fetching and delivering plate 7, the translation distance of fetching and delivering plate 7 is obtained by the stroke of master cylinder 1 and the stroke addition of secondary cylinder 2.
