Conveying equipment and conveying bent pipe thereof

Abstract

The invention discloses a conveying bent pipe and conveying equipment with the conveying bent pipe. The conveying bent pipe comprises an outer pipe and an inner pipe; an adhesive layer is arranged between the outer pipe and the inner pipe; the inner pipe is spliced by at least two inner pipe sections; the end faces of the inner pipe sections form an end face of the inner pipe; and splicing seams among the inner pipe sections and a centre line of the conveying bent pipe are parallel. The provided conveying bent pipe has the advantages of contributing to guaranteeing the adhesion quality, improving the flatness of an inner wall surface of the inner pipe, along with easier manufacture, higher yield, easier guarantee of matching accuracy of the inner pipe and the outer pipe, and capacity of meeting the requirement for mass production. In addition, when the inner pipe sections are subjected to higher impact force, proper displacement can be generated among the inner pipe sections due to the presence of the splicing seams so as to facilitate transferring the impact force to the high-intensity outer pipe and make the outer pipe play a role in protection, so that the impact resistance of the inner pipe and the integral intensity of the conveying bent pipe are improved. Therefore, the conveying bent pipe has the advantages of better manufacturing technology and higher usability.

Description

technical field [0001] The invention relates to a related technology of a delivery pipe, in particular to a delivery elbow and delivery equipment with the delivery elbow. Background technique [0002] When a concrete pump truck is used for construction work, the inner wall of the delivery pipe is subjected to the erosion and wear of the concrete slurry, which makes the wear resistance of the delivery pipe very critical. The wear resistance is not only related to the service life of the delivery pipe The length will also affect the working stability of the concrete pump truck. [0003] The conveying pipe is connected by a conveying straight pipe and a conveying elbow; in use, the conveying elbow must bear the impact caused by the turning of the concrete mud; therefore, the wear resistance and strength of the conveying elbow become an important factor affecting the overall life of the conveying pipe factor. In order to improve the wear resistance of the delivery elbow, vario...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of elbow is: the manufacturing process is relatively complicated, which makes its production cost relatively high; and the casting is prone to defects, making the quality of the elbow very unstable

This technical problem exists not only in the conveying pipe for conveying concrete slurry, but also in the conveying elbow for conveying ash and slag with similar properties to concrete mud
