Embodiment Construction
[0013] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.
[0014] figure 2 It is a structural schematic diagram of a preferred embodiment of the concrete pump concrete piston of the present invention, as figure 2 As shown, this preferred embodiment mainly includes a front cover plate 1, a piston body 3, a rear cover plate 7, a connecting rod 8, a concrete sealing body 5 and a guide ring 4 which are set on the outer ring of the piston body 3, and are set on the rear cover plate 7. The dust-proof ring 6 of the outer ring, the back cover 7 and the connecting rod 8 are integrated. The two are an integral structure. Four screws 2 are evenly distributed around the connecting rod 8 on the back cover 7 to fasten the rear covers arranged in sequence. Plate 7, piston body 3 and front cover plate 1, the three are drilled and locked by screw 2 in turn, and the intervals between the four screws 2 are at an a...

A concrete piston for a concrete pump comprises a front cover plate, a piston body, a rear cover plate, a connecting rod, a concrete sealing body and a guide ring sleeved on an outer ring of the piston body and a dust ring sleeved on an outer ring of the rear cover plate, wherein the rear cover plate is integrated with the connecting rod; and at least two screws are uniformly distributed on the rear cover plate surrounding the connecting rod and fasten the rear cover plate, the piston body and the front cover plate which are sequentially distributed. Compared with the prior art, the concrete piston for the concrete pump has the advantages that the number of the screws is greatly reduced, the weight is reduced, the cost is saved, the assembly and maintenance are simple and convenient, and easily damaged parts such as the concrete sealing body, the guide ring and the dust ring are convenient to replace.
Description
technical field [0001] The invention relates to the field of concrete machinery, in particular to a concrete piston for a concrete pump. Background technique [0002] During the pumping process of the concrete conveying system, the main oil cylinder drives the concrete piston to reciprocate in the conveying cylinder to press the concrete into the conveying pipeline. The current concrete piston structure is as figure 1 As shown, it mainly includes a connecting rod 8, a baffle 7, a concrete sealing body 5, a piston body 3 and a front cover 1, wherein the connecting rod 8, the front cover 1 and the baffle 7 are respectively fixed on the piston by multiple sets of screws 2. On the body 3, the piston body 3 also has corresponding positioning bosses, which are respectively matched with the baffle plate 7, the guide ring 4 and the concrete sealing body 5. The dustproof ring 6 is set on the outer ring of the baffle plate 7, and the guide ring 4 is set on the outer ring of the baffl...
