Fig. 2 is that A-A in Fig. 1 is to sectional structure schematic diagram.
Wherein in Fig. 1 and Fig. 2, the corresponding relation between Reference numeral and component names is:
1, elephant trunk, 11, interior pipe, 12, outer tube, 13, liner plate.
Detailed description of the invention
For the object, technical scheme and the advantage that make the utility model embodiment clearly, belowIn connection with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodimentCase is clearly and completely described, and obviously, described embodiment is of the present utility model oneSection Example, instead of whole embodiment. Based on the embodiment in the utility model, thisIt is every other that exercising ordinary skill obtains under the prerequisite of not making creative workEmbodiment, belongs to the scope of the utility model protection.
As shown in Figure 1, the utility model provide a kind of adopt that bilayer sleeve is wear-resisting can selfreparingType concrete chute 1, mainly for delivery of concrete, in elephant trunk 1 comprises interior pipe 11 and is enclosed withinOuter tube 12 on pipe 11 leaves gap, in institute between described interior pipe 11 and described outer tube 12The two ends of stating outer tube 12 are provided with the liner plate 13 matching with described gap shape and size (as figure2 is shown), described liner plate 13 and interior pipe 11 gap described in shutoff that is connected with outer tube 12, simultaneouslyLiner plate 13 also plays the effect that interior pipe 11 and outer tube 12 are connected and fixed. The utility model providesElephant trunk 1, adopt double-layer tube wall form hollow gap, when transport concrete, even interior pipeAfter 11 damages, the concrete in course of conveying can enter and fill interior pipe through interior pipe 11 breakage11 and outer tube 12 between gap, block breakage, form the new concrete protective shell of one deck,This elephant trunk is made to possess self-regeneration function, without the need to additionally repairing, safeguarding, comparatively economicalPractical; After interior pipe 11 is damaged, elephant trunk 1 can continue to use, and improves the use longevity of elephant trunk 1Life, and as long as outer tube 12 does not have damaged elephant trunk 1 just can reuse always, can reduceThe construction cost of concrete delivery, improves efficiency of construction.
It should be noted that the elephant trunk that the utility model provides, also can be multilayer sleeve combinationStructure, as the destination that three layers of sleeve pipe, four layers of sleeve pipe also can be realized the application, its aim is not de-From design philosophy of the present utility model, of the present utility model protection domain should be belonged to. .
Preferably, when elephant trunk is long, be also provided with multiple liner plates at the middle part of described outer tube 1213, interior pipe 11 and the bonding strength of outer tube 12 can be increased, ensure that the intensity of elephant trunk 1 is with steadyQualitative.
Wherein, described interior pipe 11 is coaxial with described outer tube 12, and described interior pipe 11 with described outsideThe length of pipe 12 is identical, the length of elephant trunk 1 can be designed, at interior pipe according to concrete demand11 and outer tube 12 between form the gap of ring-type, as shown in Figure 1, described liner plate 13 is with interiorThe ring-type steel plate that pipe 11 and outer tube 12 weld together, for blocking gap, and in connectionPipe 11 and outer tube 12; It should be noted that liner plate also can adopt other connected mode and outer tubeConnection, as joined by bolts etc., also can realize the application's object.
Wherein, described outer tube 12 is steel pipe, the pipe fitting that described interior pipe 11 is made for high-abrasive material,Preferably, pipe 11 is cast iron pipe, and cast iron pipe anti-wear performance is better, interior pipe 11 can be extended brokenThe time of damaging, the service life of pipe 11 in increasing.
It should be noted that, the material of described interior pipe 11 is not limited only to cast iron, high strengthSteel pipe, inorganic composite materials tubing etc. also can meet wear-resisting performance, and its aim does not depart from this realityBy novel design philosophy, of the present utility model protection domain should be belonged to.
In sum, the elephant trunk that the utility model provides, outside comprising interior pipe and overlapping on inner pipePipe leaves gap, is provided with at the two ends of described outer tube between described interior pipe and described outer tubeWith the liner plate that described gap shape and size match, described liner plate is connected with inner and outer tubesGap described in shutoff, liner plate also plays the effect that inner and outer tubes are connected and fixed simultaneously. This realityWith the novel elephant trunk providing, adopt the hollow gap that double-layer tube wall forms, when transport concrete,Even after interior pipe damages, the concrete in course of conveying can enter through interior pipe breakage and fillGap between interior pipe and outer tube, blocks breakage, forms the concrete protective shell that one deck is new,Possess self-regeneration function, without the need to additionally repairing, safeguarding, comparatively economical and practical; InteriorAfter pipe is damaged, elephant trunk can continue to use, and improves the service life of elephant trunk, and as long as outer tubeDo not have damaged elephant trunk just can reuse always, can reduce being constructed into of concrete deliveryThis, improve efficiency of construction; Simultaneously, pipe is high-abrasive material pipe fitting, and its anti-wear performance is superior.
