Abstract
The utility model relates to a concrete piston for concrete pump which comprises a link rod, a guiding ring, a piston body, a concrete sealing body and a pressing plate. The utility model is characterized in that the pressing plate has a barrel lid shaped structure, the piston body and the concrete sealing body are sheathed on the cylinder wall of the external cylinder, and the link rod is connected with the pressing plate. With the improving of the concrete piston structure, the connection board can be directly connected with the pressing plate, the structure of the piston body is simplified, the weight of the concrete piston is lightened, the maintainability of the concrete piston is increased, and the service life of the concrete piston is profitable to be increased.
Description
Technical field:
The utility model relates to the construction implement field, is specifically related to the improvement of pump usefulness concrete piston in the concrete pump distribution system.
Background technique:
Concrete pump relies on the to-and-fro motion of concrete piston in carrying cylinder in the pumping process, concrete is pressed in the conveyance conduit.Concrete piston common structure as shown in Figure 1, it mainly is made up of parts such as connecting rod, baffle plate, concrete seal, piston body and pressing plates, wherein piston body is the central module that interconnects with each part, its structure shape complexity, the processing charges height, connecting plate, baffle plate and pressing plate join with it by screw respectively, because the screw number is too many, assembling and dismounting are very inconvenient, and maintenance is poor.Particularly concrete seal, guide ring and dust ring all belong to easily damaged parts, need frequent dismounting concrete piston, and it is more outstanding to make that its maintenance difference gets defective.
The model utility content:
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, provides a kind of concrete piston simple in structure, that be easy to assembling and maintenance to improve structure.
Technical problem of the present utility model is to realize by following technological scheme.It comprises connecting rod, guide ring, piston body, concrete seal and pressing plate, it is characterized in that described pressing plate is a cover shape structure, and piston body and concrete seal all are placed on its urceolus barrel, and connecting rod is connected with pressing plate.
The utility model directly joins connecting plate and pressing plate by improving the concrete piston structure, has simplified piston body structure, has alleviated the weight of concrete piston, has improved the maintainalbility of concrete piston, the working life that helps improving the concrete piston.
Description of drawings:
Fig. 1 is the concrete piston structure figure of prior art;
Fig. 2 is the utility model structural drawing.
Among the figure:
The 1-connecting rod; The 2-screw; The 3-screw;
The 4-baffle plate; The 5-dust ring; The 6-guide ring;
The 7-screw; 8-concrete seal; The 9-piston body;
The 10-pressing plate; The 11-connecting rod; The 12-screw;
The 13-piston body; The 14-pressing plate.
Embodiment:
As shown in Figure 1, concrete piston in the prior art mainly is made up of parts such as connecting rod 1, baffle plate 4, concrete seal 8, piston body 9 and pressing plates 10, wherein connecting rod 1, pressing plate 10 and baffle plate 4 are fixed on the piston body 9 by screw 3, screw 7 and screw 2 respectively, go back correspondence on the piston body 9 and offer positioning boss, match with baffle plate 4, guide ring 6 and concrete seal 8 respectively, dust ring 5 is placed in baffle plate 4 outer rings, and guide ring 6 is placed in piston body 9 outer rings.Must earlier pressing plate 10 be loaded on the piston body 9 during assembling,, and then connecting rod 1 and baffle plate 4 be loaded on the piston body 9 with fixing concrete seal 8.When needing repairing or change concrete seal 8, then must earlier connecting rod 1 be disassembled, could dismantle pressing plate 10, thereby bother very much.
The utility model improves at above-mentioned defective, as shown in Figure 2, former connecting rod 1 and baffle plate 4 are combined to form an integral body, form a new connecting rod 11, by piston body 13 location, dust ring 5 is placed on the connecting rod 11 corresponding outer rings that are provided with, pressing plate 14 is designed to the cover form, and its side is concrete seal 8 location, and piston body 13 and concrete seal 8 all are placed on the pressing plate 14 urceolus barrels, guide ring 6 is placed in piston body 13 outer rings, and connecting rod 11 links together by screw 12 and pressing plate 14.Like this, pressing plate 14 directly is connected with connecting rod 11, has reduced the number of attachment screw, and assembling and dismounting are become easily, and 13 of piston bodies play pressing plate 14 location and support guide rings 6, and structure has become simply, has also reduced processing cost simultaneously.
