Description
Technical field
The present invention relates to mass transport correlation technique, be specifically related to a kind of composite structure conveying straight tube of material handling machinery, also relate to the manufacture method of this composite structure conveying straight tube and use this composite structure to carry the material handling machinery of straight tube.
Background technique
Delivery pipe is material handling machinery (as concrete mixer, material distributing machine etc.) requisite auxiliary equipment, and material comprises concrete etc., only has and just can reach remote normal conveying by the continuous transmission of delivery pipe.
Delivery pipe General Requirements inwall has higher wear resistance, also requires that entirety has good toughness, and weight can not be too heavy in addition, otherwise the equipment of weight limits will be made overweight, also causes dismounting difficulty large simultaneously, affect working efficiency, and Security is not high.
At present, when carrying out constructions work, generally by conveying mechanism by concrete conveyance to predetermined place, to implement predetermined operation.In delivering concrete process, concrete arrives predetermined place by delivery pipe, and delivery pipe inwall needs to continue continuous erosion and the wearing and tearing of bearing concrete mud, like this, delivery pipe is after the concrete of transfer predetermined amounts, just need to change, change the efficiency that delivery pipe can affect concrete conveyance on the one hand frequently, too increase the cost of concrete conveyance on the other hand.
In order to reduce the replacement frequency of delivery pipe, reduce concrete conveying cost, the current multiple technologies scheme that have employed is to extend the working life of delivery pipe.According to the difference of its principle, roughly comprise two kinds of modes.
Mode is by increasing the wall thickness of delivery pipe to improve a working life for delivery pipe, and then the replacement frequency of minimizing delivery pipe.But this method can strengthen the weight of engineering machinery jib undoubtedly, when delivering concrete mud, be very easy to jib is transshipped, cantilever support fracture, jib side plate problems of crack can be caused time serious, cause security incident.
Another kind of mode be hardness by improving delivery pipe to increase the wear resistance of delivery pipe, and then working life of increase delivery pipe.Increase hardness and generally comprise again two kinds of modes, one is make delivery pipe with special high-abrasive material, and as cast with high manganese steel or special high-abrasive material, the delivery pipe high cost that this mode makes, is not suitable for concrete conveying.Two is carry out Quenching Treatment to delivery pipe, to improve the hardness of carrier wall, impact resistance and the toughness of the delivery pipe of this method manufacture are lower, especially hoist or need quickly delivering concrete time, delivery pipe all will bear higher pressure, under elevated pressures effect, easily cause delivery pipe embrittlement, booster, cause larger security incident.
Therefore, all there is safety risks in the method extending its working life by the mode of the wall thickness or raising delivery pipe hardness that increase delivery pipe.
For example, refer to Fig. 1, Fig. 1 is the cross section structure schematic diagram of the delivery pipe of a kind of material handling machinery in prior art.As shown in Figure 1, this delivery pipe 10 is single layer structure, comprises body 11 and flange 12, and wherein, this body 11 adopts steel or alloyed steel usually, and this flange 12 adopts plain carbon steel usually.This delivery pipe 10 is because taking into account toughness and wear resistance, and its inwall wear resistance is limited, and weight lays particular stress on simultaneously.
