Embodiment
Hereinafter will and combine embodiment to specify the utility model with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
As depicted in figs. 1 and 2; First embodiment according to the utility model; Delivery pipe is a straight tube; Comprise pipe fitting 10, be arranged on the link 20 at pipe fitting 10 two ends and be set in the reinforcement tube 30 outside the pipe fitting 10, the two ends of reinforcement tube 30 are fixedly installed on the link 20, and this fixed connection mode for example connects for welding, bolt or be bonding.Wherein between reinforcement tube 30 and pipe fitting 10, be provided with buffer gap 31, buffer gap 31 and evenly distributes between the outer wall of the inwall of reinforcement tube 30 and pipe fitting 10.
When delivering concrete, concrete can push and impact pipe fitting 10, after pipe fitting 10 is received impact, because the existence of buffer gap 31 can make pipe fitting 10 suffered impact forces reduce, reduces the suffered impact force of pipe fitting 10, thereby reduces the wearing and tearing of pipe fitting 10.When pipe fitting 10 was worn out, buffer gap 31 also can form buffering to concrete impact, reduced in the transmission and concrete transmission process the impact and the wearing and tearing of reinforcement tube 30, improved the explosion-proof ability of delivery pipe, strengthened the Safety performance of delivery pipe.
See also shown in Figure 2ly, wherein d0 is the wall thickness of pipe fitting 10, and d2 is the thickness of reinforcement tube 30, and d1 is the thickness of buffer gap 31.The thickness of buffer gap 31 is 3～5mm, so that when forming effective buffering, makes reinforcement tube 30 form effective protective action to pipe fitting 10.
Please combine referring to shown in Figure 3, according to second embodiment of the utility model, delivery pipe also is a straight tube, and itself and first embodiment's difference is that the set-up mode of the link 20 at pipe fitting 10 two ends is different.The link at pipe fitting 10 two ends among first embodiment was located at two ends in 20 minutes, and pipe fitting 10 is between two links 20.And the two ends of the pipe fitting 10 in the present embodiment are fixedly connected with stop lug, are arranged on the interior retaining wall of this holding flange through flange plate then, thereby form link 20.This link 20 is the outer wall stop lug inboards that are positioned at pipe fitting 10, rather than is positioned at the end face outside of pipe fitting 10.
Please combine referring to shown in Figure 4, according to the 3rd embodiment of the utility model, delivery pipe is a bend pipe, includes pipe fitting 10 and the reinforcement tube 30 that is set in outside the pipe fitting 10, between pipe fitting 10 and the reinforcement tube 30 buffer gap is set.The link of present embodiment lays respectively at the two ends of pipe fitting 10, and one-body molded with pipe fitting 10.First embodiment and second embodiment also can adopt this structure.
