Abstract
The utility model belongs to the technical field of power device, especially, relate to a pneumatic means. The pneumatic device comprises two cylinders, wherein a piston and a piston rod are arranged in each cylinder, a piston sealing ring is arranged at the position of each piston, the two cylinders are arranged in parallel in the same cavity shell, the rigidity of the cylinders is enhanced, the cylinders can be prevented from being broken by ores and other heavy objects, and the two cylinders are communicated during working, so that the stroke can be shortened.
Description
Technical field
The utility model belongs to field of power equipment technology, especially relates to a kind of Pneumatic actuator.
Background technique
The parking lot in each stage casing of existing plumbous zinc ore cage hoisting adopts the long-stroke pneumatic car puller to push away the mode of mine car tinning.Once push away two mine cars, the cylinder level is installed between the yard tracks.Cylinder is two sections structures that the processing butt joint forms, and its piston packing ring adopts two L type rubber rings.But existing rubber ring is ground away very soon, and the cushion rubber flange is involved between piston and the casing wall sometimes, and with seizure of piston, car puller can not be normal.The reason that produces above-mentioned phenomenon has: 1. piston structure is simple and crude, and piston and casing wall gap are big, and L type rubber ring thickness is 3mm only, width 14mm, and L type rubber ring bearing capacity and sealability can not adapt to the hard work of long-stroke pneumatic car puller; Piston rod is from great, and with the compressive strain of L type cushion rubber, the gap appears in L type cushion rubber and casing wall, causes seriously and collaborates, and make the cushion rubber flange; The cylinder sectional making, two sections cylinder joint centerings are poor, have dislocation, and the sharp edge shoulder occurs, the cylinder inner wall rough surface, even have the part to have unprocessed hair side, so the wear extent of casing wall is big.
The model utility content
The utility model can provide a kind of sealing effect better, and design is Pneumatic actuator more reasonably.
In order to solve the problems of the technologies described above, provide following technological scheme: Pneumatic actuator, comprise two cylinders, cylinder interior is provided with piston, piston rod, and the piston place is provided with piston packing, and described two cylinders are set up in parallel in same cavity enclosure interior.
Adopt above-mentioned technological scheme, in the utility model, Pneumatic actuator comprises two cylinders, and cylinder interior is provided with piston, piston rod, the piston place is provided with piston packing, described two cylinders are set up in parallel in same cavity enclosure interior, have strengthened the rigidity of cylinder, can prevent from being smashed cylinder by ore and other weight, two cylinders are communicated with during work, can shorten stroke.
Further, described piston packing is biserial Y type oil-resistant rubber ring, and the bearing capacity of piston and sealability are significantly improved, and has improved quality of processing simultaneously.
Further, the joint of described piston and piston rod head is provided with seal ring, and during the to-and-fro motion of damper piston bar, the impact force to piston brings shields to piston.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model Pneumatic actuator;
Fig. 2 is the structural representation of piston packing in the utility model Pneumatic actuator.
Embodiment
As shown in Figure 1, 2: Pneumatic actuator, comprise two cylinders 6, cylinder 6 inside are provided with piston 1, piston rod 2, piston 1 place is provided with piston packing 3, two cylinders 6 are set up in parallel in same cavity housing 4 inside, piston packing 3 is biserial Y type oil-resistant rubber ring, and described piston 1 is provided with seal ring with the joint of piston rod 2 heads.
In the present embodiment, Pneumatic actuator, comprise two cylinders 6, cylinder 6 inside are provided with piston 1, piston rod 2, and piston 1 place is provided with 3, two cylinders 6 of piston packing and is set up in parallel in same cavity housing 4 inside, strengthened the rigidity of cylinder 6, can prevent from being smashed cylinder 6 by ore and other weight, two cylinders 6 are communicated with during work, can shorten stroke; Piston packing 3 is biserial Y type oil-resistant rubber ring, and the bearing capacity of piston 1 and sealability are significantly improved, and has improved quality of processing simultaneously; Described piston 1 is provided with seal ring with the joint of piston rod 2 heads, and during 2 to-and-fro motion of damper piston bar, the impact force of bringing for piston 1 shields to piston 1.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; should be considered as protection domain of the present utility model, these can not influence effect and practical applicability that the utility model is implemented yet.
Claims (2)
