Abstract
The utility model provides a concrete composite conveying straight pipe which mainly solves the technical problems that an inner pipe moves up or a wear-proof sleeve is washed out, and the end opening of an existing concrete composite conveying straight pipe is worn out and loses effectiveness in the process of operating and dredging a blocked pipe. The concrete composite conveying straight pipe is technically characterized by comprising a flange (1), a wear-proof sleeve (2) and a composite straight pipe body (3). A wear-proof sleeve chamfer (5) is arranged on the outer side of the connecting end opening of the wear-proof sleeve (2) and the composite straight pipe body (3), and fixedly connects the wear-proof sleeve (2) and the composite straight pipe body (3) in a building up welding mode. The flange (1) is installed on the periphery of the wear-proof sleeve (2) and coats the connecting end opening of the wear-proof sleeve (2) and the composite straight pipe body (3), so that the flange (1) and the composite straight pipe body (3) are fixedly connected in a build up welding mode. The concrete composite conveying straight pipe is mainly used in concrete pump trucks in the building construction field.
Description
Technical field
The utility model relates to the automobile-used concrete of a kind of concrete pump and carries the compound conveying straight tube of straight tube, particularly a kind of concrete.
Background technique
Present popularizing owing to construction machineization, the pump truck that is used for the concrete conveying becomes the visual plant of construction, in concrete course of conveying, conveyance conduit is a most general easily worn part, concrete mud is delivered to the predetermined area by delivery pipe under certain pressure, carry out concrete cast or perfusion operation.
In concrete course of conveying, conveyance conduit will bear persistency impact wear and the corrosion that produces when concrete mud flows on the one hand; Conveyance conduit also will bear the pressure effect of concrete mud on the other hand.Factor of these two fermentation just requires concrete conveying pipe to possess higher wear resistance, good toughness and intensity.
Be wear resistance, intensity, the toughness reguirements of satisfying concrete delivery pipe, that generally uses at present all is the two-layer compound delivery pipe, and inner tube material is the alloyed steel of high wear resistance, and outer tube material is low-carbon alloy steel, and there is the flange connection at two ends, inlay wear-resistant sleeve in the flange.Owing to be not metallurgy combination between the composite pipe, in conveying, have following defective: 1, the composite force of outer tube and interior pipe a little less than, after in operation process, plugging occurring, operator generally take to take apart discharge end, carry out comb by pump concrete or water, manage very easily play in the comb process or be rushed out; 2, the easy wear out failure in compound straight tube port.
Summary of the invention
The purpose of this utility model provide a kind of in operation and plugging comb process, can prevent in pipe the generation that play or wear-resistant sleeve are rushed out phenomenon takes place, can significantly reduce the compound conveying straight tube of concrete of the wearing and tearing of straight tube port simultaneously.
The technological scheme that its technical problem that solves the utility model adopts is: comprise flange 1, wear-resistant sleeve 2 and compound straight tube 3, wear-resistant sleeve chamfering 5 is arranged and wear-resistant sleeve 2 and 3 built-up welding of compound straight tube are connected firmly in be connected with compound straight tube 3 arranged outside of port of wear-resistant sleeve 2, flange 1 is installed on wear-resistant sleeve 2 peripheries and coats and covers wear-resistant sleeve 2 and place, composite pipe 3 connecting ports, and flange 1 and composite pipe 3 built-up welding connect firmly.
Circumferential weld 4 in flange 1 is reserved with wear-resistant sleeve 2, the gap of interior circumferential weld 4 is 0-0.5mm, wear-resistant sleeve 2 and compound straight tube 3 built-up welding peripheries and flange 1 inwall match.
Described compound straight tube 3 is to adopt the bimetal pipe interference to be composited, and flange 1 overlaps with the medial axis of compound straight tube 3,
Fit up gap between compound straight tube 3 and the wear-resistant sleeve 2 is 0-0.5mm.
The beneficial effects of the utility model have provided a kind of compound straight tube of concrete of split-type design structure, boxing and the internal pipe of wear-resistant sleeve position in utilizing, can effectively prevent from managing the generation play in delivery pipe is in operation or plugging comb process, or even be rushed out, by the gap between control wear-resistant sleeve end face and the compound straight tube end face, prolong the cycle that compound straight tube end wear lost efficacy greatly.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
Embodiment 1, the utility model provides a kind of concrete compound conveying straight tube, it is characterized in that: comprise flange 1, wear-resistant sleeve 2 and compound straight tube 3, wear-resistant sleeve chamfering 5 is arranged and wear-resistant sleeve 2 and 3 built-up welding of compound straight tube are connected firmly in be connected with compound straight tube 3 arranged outside of port of wear-resistant sleeve 2, flange 1 is installed on wear-resistant sleeve 2 peripheries and coats and covers wear-resistant sleeve 2 and place, composite pipe 3 connecting ports, flange 1 and composite pipe 3 built-up welding connect firmly, the steadiness of pipe in improving.
Embodiment 2; the utility model flange 1 and composite pipe 3 built-up welding connect firmly employing be in; outer double-deck boxing connects; utilize auxiliary mould to guarantee that flange 1 overlaps with the medial axis of compound straight tube 3; it is carried out outer boxing; boxing 4 in carrying out behind the location; the width of interior circumferential weld 4 and height are just identical substantially with wear-resistant sleeve chamfering 5 sizes of wear-resistant sleeve 2; utilize hydraulic-feed mechanism that wear-resistant sleeve 2 is pressed in the flange 1; wear-resistant sleeve 2 end faces and compound straight tube 3 end faces are fitted; wear-resistant sleeve 2 chamferings and interior circumferential weld 4 are fitted; fit up gap between compound straight tube 3 and the wear-resistant sleeve 2 is 0-0.5mm; flange 1 fastening wear-resistant sleeve 2; 2 pairs of compound straight tube ports of wear-resistant sleeve also play a very good protection, and are not caused losing efficacy by unexpected wearing and tearing, and pipe is gone out in effectively preventing under flange links closely.Consult Fig. 1 to Fig. 6, all the other are with embodiment 1.
