Abstract
The utility model provides a structure of driving an oil cylinder by a concrete pump swinging valve. The structure is characterized in that a plunger piston is arranged in a cylinder body; a buffering cavity is arranged in the middle of the plunger piston; a fixed cylinder cover is mounted at the end part of the cylinder body; a fixed buffering plunger piston is mounted in the middle of the inner end of the cylinder cover by using a bolt; the diameter of the outer diameter of the buffering plunger piston is less than the diameter of the inner circle of the buffering cavity; the outer circle of the buffering plunger piston is provided with a plurality of annular grooves; rubber rings are embedded into the annular grooves of the buffering plunger piston; the diameters of the outer circles of the rubber rings from the end part to the bottom part of the buffering plunger piston are gradually increased; and the diameter of the outer circle of the largest rubber ring is less than the diameter of the inner circle of the buffering cavity. The structure disclosed by the utility model has the advantages of simple structure and better buffering effect.
Description
Technical field
The utility model relates to concrete pump, is specifically related to the structure that concrete pump pendulum valve drives oil cylinder, belongs to the concrete pump technical field.
Background technique
the pendulum valve of concrete pump is the important spare part in the concrete output mechanism, its working method is to be completed by the action of doing the push-and-pull shape by the plunger piston fluid pressure cylinder that is arranged on its both sides, the hydraulic shock that produces at work in order to reduce oil cylinder, and the harmful effect to hydraulic system and pendulum valve that causes thus, existing oil hydraulic cylinder generally all is designed to the oil hydraulic cylinder with damping device, reduce the harmful effect that hydraulic cushion brings, at present, although existing these cushion cylinder structures are not quite similar, but, generally there is complex structure, the defective that cushioning effect is relatively poor.
Summary of the invention
The purpose of this utility model is: drive oil cylinder at the existing defects of context buffer for existing concrete pump pendulum valve, the utility model provides a kind of novel concrete pump pendulum valve to drive the structure of oil cylinder, overcomes existing concrete pump pendulum valve and drives the existing defects of oil cylinder.
the technological scheme that the above-mentioned purpose that realizes the utility model adopts is: described a kind of concrete pump pendulum valve drives the structure of oil cylinder, it comprises plunger, cylinder body, buffer plunger, rubber ring, cylinder cap, bolt forms, it is characterized in that: plunger is arranged on and is shaped with buffer cavity in cylinder body in the middle of described plunger, fixedly cylinder cap is installed in end at cylinder body, fixedly buffer plunger is installed with bolt in centre in the cylinder cap inner end, the outside diameter of described buffer plunger is less than the interior circular diameter of buffer cavity, be shaped with some circular grooves on the cylindrical of buffer plunger, be inlaid with rubber ring in the circular groove of buffer plunger, the outside diameter of described rubber ring from the end of buffer plunger to the bottom increases gradually, and the outside diameter of maximum rubber ring is less than the interior circular diameter of buffer cavity.
Cushioning principle of the present utility model is: when plunger motion near buffer plunger the time, at this moment, buffer plunger begins to insert the inside of buffer cavity, hydraulic oil in buffer cavity is extruded from rubber ring and buffer cavity formed gap, because the diameter of rubber ring strengthens gradually, so, the also minimizing gradually of the formed gap of rubber ring and buffer cavity, the buffering resistance strengthens gradually.
Beneficial effect: can be found out by structure principle chart of the present utility model and working principle, the utlity model has simple in structurely, cushioning effect is advantage preferably.
Description of drawings
Accompanying drawing is structure principle chart of the present utility model.
Shown in figure: 1, plunger; 2, cylinder body; 3, buffer plunger; 4, rubber ring; 5, cylinder cap; 6, bolt; 7, buffer cavity.
