Abstract
The utility model discloses a piston for a concrete pump, which comprises a connecting rod, a baffle, a pressure plate, a piston body, a sealing body and a guide ring, wherein the pressure plate is arranged at the rear end of the connecting rod; the piston body and the sealing body are respectively sleeved on an outer ring of the connecting rod; the guide ring is sleeved on the outer ring of the piston body; the connecting rod and the pressure plate are integrated into a whole; and the baffle is in threaded connection with the connecting rod. According to the utility model, the integral structure of the piston can be simplified, so that the convenience in maintenance and disassembly can be realized and the cost can be effectively saved by reducing the total weight.
Description
Technical field
The utility model relates to a kind of building machinery field, particularly relates to a kind of concrete Piston for pump.
Background technique
In the concrete pumping process, oil cylinder promotion concrete piston moves reciprocatingly in carrying cylinder concrete is pressed in the conveyance conduit.As shown in Figure 1, be the structural representation of existing a kind of concrete Piston for pump 10, it mainly includes parts such as connecting rod 11, baffle plate 12, dust ring 13, guide ring 14, piston body 15, seal 16, pressing plate 17 and forms.Wherein, connecting rod 11, baffle plate 12, pressing plate 17 need respectively to be fixed on the piston body 15 by three groups of screws 181,182,183, the also corresponding location concave station that offers on the piston body 15, match with baffle plate 12, guide ring 14, piston body 15 respectively, dust ring 13 is sleeved on the outer ring of baffle plate 12, guide ring 14 is sleeved on the outer ring of piston body 15, and the while is fixing seal body 16 further.During assembling, need earlier pressing plate 17 to be loaded on the piston body 15, then connecting rod 11 and baffle plate 12 are loaded on the piston body 15.Need repairing or when changing seal 16, need earlier connecting rod 11 and baffle plate 12 are pulled down, could dismantle pressing plate 17.
In sum, the concrete Piston for pump of prior art is the structure shape complexity not only, and the attachment screw number is more, weight is bigger, and in practical operation, seal, guide ring and dust ring are easily damaged parts, need often to change, yet existing structure must be pulled down connecting rod earlier, just can pull down pressing plate, and operation is comparatively complicated, all brought inconvenience for assembling and dismounting, maintainability is poor, has reduced working efficiency to a certain extent, so remain to be improved.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of concrete Piston for pump, simplifies the overall structure of piston with realization, thereby reaches the effect of maintenance and convenient disassembly.
For achieving the above object, the utility model proposes a kind of concrete Piston for pump, include connecting rod, baffle plate, be arranged on the pressing plate of described connecting rod rear end, be socketed in piston body and the seal on the described connecting rod outer ring respectively and be socketed in guide ring on the described piston body outer ring, described connecting rod and described pressing plate are set to an overall structure, and described baffle plate and described connecting rod are by being threaded togather.
Further, described baffle plate is provided with first boss that is used for cooperating with described piston body the location.
Further, also be provided with on the described piston body and be used for cooperating first concave station of location and be used for cooperating second concave station of locating with described guide ring with described baffle plate.
Further, also be socketed with dust ring on the outer ring of described baffle plate.
Further, to be boss stepped in the outer ring of described connecting rod.
According to the utility model, because pressing plate and connecting rod are an integrated structure, simplified overall structure, connecting rod is threaded with baffle plate, can effectively avoid the use of fastening pieces such as screw of the prior art, alleviated gross weight, effectively save cost, made assembling and dismounting become convenient simultaneously, improved maintainalbility, further increase working life, significantly improved business efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the concrete pump of a prior art structure of piston schematic representation;
Fig. 2 is the concrete pump structure of piston schematic representation according to the utility model one mode of execution.
Embodiment
Below, by exemplary mode of execution the utility model is specifically described.Yet should be appreciated that under the situation that is not having further narration element, device and feature in mode of execution also can be attached in other mode of execution valuably.
As shown in Figure 2, be concrete Piston for pump 20, include connecting rod 21, baffle plate 22, pressing plate 27, piston body 25, seal 26 and guide ring 24 according to a mode of execution of the present utility model.For the ease of fixed piston body 25 and seal 26, the shape of boss ladder is arranged in the outer ring of connecting rod 21, piston body 25 and seal 26 are socketed in respectively on the outer ring of connecting rod 21 successively.Simultaneously, on the outer ring of piston body 25, also be provided with guide ring 24, thereby can play the effect of guiding.
It is worthy of note, for simplified structure, make the assembling of concrete Piston for pump 20 and dismantle more convenient, pressing plate 27 is arranged on the rear end of connecting rod 21, and be arranged to an overall structure with connecting rod 21, and reduce the number of part with this, cancelled fastening piece simultaneously, alleviated gross weight, further provided cost savings.
Meanwhile, on the external diameter of connecting rod 21, be provided with outside thread, the internal diameter of baffle plate 22 is provided with the internal thread that is complementary with outside thread, block 22 can link together by screw thread and connecting rod 21 like this, effectively avoided using other fastening piece, as screw of the prior art etc., further play the purpose that alleviates piston weight.
In order to play the dust-tight effect, on the outer ring of baffle plate 22, also be provided with dust ring 23.Meanwhile, in order to guarantee each part mounting stability and reliability further, on baffle plate 22, also be provided with first boss 221, be used for cooperating the location with piston body 25, on piston body 25, also be provided with first concave station 251 and second concave station 252, wherein first concave station 251 be used for baffle plate 22 on first boss 221 that is provided with cooperate the location, second concave station 252 is used for cooperating the location with guide ring 24.
According to concrete Piston for pump of the present utility model, integral structure by pressing plate and connecting rod, and being threaded of connecting rod and baffle plate, can effectively avoid the use of fastening pieces such as screw, alleviated integrally-built weight, effectively saved cost, when needs are changed and keep in repair part, more easily realize the separation between each parts simultaneously, make assembling and dismounting become convenient, strengthen working life, improved economic benefit.
Though should be pointed out that by above-mentioned mode of execution the utility model is described, yet the utility model also can have other numerous embodiments.Under the prerequisite that does not break away from the utility model spirit and scope; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the utility model, but these changes and distortion all should belong in the scope that the utility model claims and equivalent thereof protect.
