Description
Technical field
The utility model relates to the mass transport correlation technique, is specifically related to a kind of composite structure delivery pipe, also relates to the material handling machinery that uses this composite structure delivery pipe.
Background technique
Delivery pipe is the requisite auxiliary equipment of material transfer equipment (like concrete mixer, material distributing machine etc.), and material comprises concrete etc., has only the continuous transmission through delivery pipe just can reach remote normal the conveying.
Delivery pipe fitness for purpose inwall has higher wear resistance, also requires integral body to have toughness preferably, and weight can not be too heavy in addition, otherwise will make the equipment of weight limits overweight, also causes the dismounting difficulty big simultaneously, influence working efficiency, and Security is not high.
At present, when carrying out constructions work, generally transmission and concrete transmission is arrived predetermined place, with the operation of implementing to be scheduled to through conveying mechanism.In the delivering concrete process; Concrete arrives predetermined place through delivery pipe, and the delivery pipe inwall need continue to bear the continuous erosion and the wearing and tearing of concrete mud, like this; Delivery pipe is behind the concrete of transfer predetermined amounts; Just need to change, frequent replacing delivery pipe can influence the efficient of transmission and concrete transmission on the one hand, has also increased the cost of transmission and concrete transmission on the other hand.
In order to reduce the replacing frequency of delivery pipe, reduce concrete conveying cost, current working life of having adopted the multiple technologies scheme to prolong delivery pipe.According to the difference of its principle, roughly comprise dual mode.
A kind of mode be wall thickness through increasing delivery pipe improving the working life of delivery pipe, and then reduce the replacing frequency of delivery pipe.But this method can strengthen the weight of engineering machinery jib undoubtedly, when delivering concrete mud, is very easy to make the jib overload, can cause jib to support fracture, jib side plate problems of crack when serious, causes security incident.
Another kind of mode be hardness through improving delivery pipe increasing the wear resistance of delivery pipe, and then increase the working life of delivery pipe.Increase hardness and generally comprise dual mode again, the one, make delivery pipe with special high-abrasive material, as casting with high manganese steel or special high-abrasive material, the delivery pipe cost that this mode is made is too high, is not suitable for concrete conveying.The 2nd, delivery pipe is carried out Quenching Treatment; To improve the hardness of carrier wall, impact resistance and the toughness of the delivery pipe that this method is made are lower, are hoisting or needs quickly during delivering concrete especially; Delivery pipe all will bear higher pressure; Under the elevated pressures effect, cause delivery pipe embrittlement, booster easily, cause bigger security incident.
Therefore, all there is Security hidden danger in wall thickness through increasing delivery pipe or the mode that the improves delivery pipe hardness method that prolongs its working life.
