The utility model includes a hydraulic tank composed of a square tank body, a piston rod, a piston head and a tank body cover board, wherein, a connecting component is arranged on the piston head which is paralleled with the piston rod, the tail of the connecting component is arranged with a movable pulley, the underside of the square tank body is connected with a connecting board, a static pulley is arranged on the connecting board, one end of the steel wire rope is fixed on the connecting board, the other end is connected with the connector after rounding the movable pulley and the static pulley. The utility model has the advantages that a set of pulley group actuating mechanism is added at the lower part of the hydraulic tank, so as to realize the hydraulic tank travel route increasing within narrow space to improve the recovery speed. The utility model is mainly used in abutting joint and automatic drop-off of the refrigeration connector.

Description

The oil hydraulic cylinder that has the sound pulley
Technical field
The utility model belongs to a kind of driving mechanism field, is specifically related to a kind of oil hydraulic cylinder.
Background technique
Oil hydraulic cylinder is an executive component important in the hydraulic system, is widely used in every field.In many occasions, owing to be subjected to the restriction of space and power source, people finish the essential action except requiring oil hydraulic cylinder, also require oil hydraulic cylinder satisfying under the situation of spatial constraints, can realize bigger stroke and also improve recovery speed as much as possible.Conventional at present solution is to adopt multistage hydraulic cylinder and improve the power source flow, and the shortcoming of this way is: can not satisfy the requirement of small space; The increase of power source flow has brought the complexity of whole system; Complex structure, reliability decrease, cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of oil hydraulic cylinder that has the sound pulley that can realize big stroke and can improve recovery speed.
Realize the technological scheme of the utility model purpose: a kind of oil hydraulic cylinder that has the sound pulley, it comprises the oil hydraulic cylinder of being made up of square cylinder body, piston rod, piston head, cylinder body cover plate, wherein, the link parallel with piston rod is installed on the described piston head, the afterbody of this connected element is equipped with movable pulley, downside at square cylinder body is connected with connecting plate, quiet pulley is installed on this connecting plate, one end of wire rope is fixed on the connecting plate, and the other end is walked around movable pulley and is connected with connector with quiet pulley.
Effect of the present utility model: utilize conventional simple and easy oil hydraulic cylinder, increased by a cover sheave block driving mechanism, be implemented in the line increment journey of oil hydraulic cylinder under the small space and improved recovery speed in cylinder lower.When the oil cylinder piston bar stretches out, drive movable pulley also with the piston head motion by connecting plate, quiet pulley only rotates and does not move, if the piston rod movement stroke is X, then the connector stroke is 2X; With should the oil cylinder piston bar regaining stroke be X, movable pulley drive connector thereupon automatically backward movement travel be 2X.Because the effect of line increment journey makes the connector stroke increase one times.The sound pulley just in time has the speedup effect simultaneously, double at identical time female connector stroke, also increased by one times so connector reclaims speed thereupon, thereby guaranteed to put in place, thereby the assurance connector can be completely retracted into the position at the appointed time when oil cylinder piston reclaims synchronously with connector.The oil hydraulic cylinder that drives quiet pulley is the transmission device of a kind of machine liquid combination, has advantages such as compact structure, reliability height, stroke are big, recovery speed doubles.
Description of drawings
A kind of hydraulic cylinder structure schematic representation that has the sound pulley that Fig. 1 provides for the utility model.
Fig. 2 is motion principle figure of the present utility model.
Among the figure: 1. piston head; 2. wire rope; 3. piston rod; 4. quiet pulley; 5. cylinder body; 6. movable pulley; 7. cylinder body cover plate; 8. connecting plate; 9. link.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of oil hydraulic cylinder that has the sound pulley, it comprises the oil hydraulic cylinder of being made up of square cylinder body 5, piston rod 3, piston head 1, cylinder body cover plate 7, it is characterized in that being equipped with on the described piston head 3 link 9 parallel with piston rod 1, the afterbody of this link 9 is equipped with movable pulley 6, downside at square cylinder body 5 is connected with connecting plate 8, quiet pulley 4 is installed on this connecting plate 8, one end of wire rope 2 is fixed on the connecting plate 8, and the other end is walked around movable pulley 6 and is connected with connector with quiet pulley 4.Wherein said link 9 can be a connecting plate, also can be connecting rod.
As shown in Figure 2, a kind of motion principle that has the oil hydraulic cylinder of sound pulley: when the cylinder piston rod 3 of oil hydraulic cylinder stretches out, piston head 3 drives movable pulley 6 also with piston head 1 motion by link 9,4 on quiet pulley rotates and does not move, if the movement travel of piston rod 3 is X, then the stroke of connector is 2X; Regaining strokes when hydraulic cylinder piston rod 3 is X, movable pulley 6 drive connectors thereupon automatically backward movement travel be 2X.
Concrete usage mode of the present utility model: the oil hydraulic cylinder that has the sound pulley is installed in the plug cover, the refrigeration connector that is installed in the ZLT pull-plug device on certain launching tube is connected with the piston rod 3 of the oil hydraulic cylinder that has the sound pulley by wire rope 2, movable pulley 6 was also with piston head 1 motion when piston rod 3 stretched out, 4 on quiet pulley rotates and does not move, its movement travel is X when piston rod 3 reaches the end, the stroke of connector of freezing this moment is 2X, the refrigeration connector is the quick plug seat of close required butt joint, and can pin by machinery.When piston rod 3 is regained strokes and is X, movable pulley 6 drive connectors thereupon automatically backward movement travel be 2X, unblank by wire rope 2, the end extracted and is retracted to by the refrigeration connector from the quick plug seat.
The utility model is mainly used in the butt joint of refrigeration connector and comes off automatically.
