Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] Such as figure 1 As shown, a self-filling elbow proposed by the embodiment of the present invention includes an elbow body 1, the elbow body 1 is in the shape of a shoe as a whole, and the elbow body 1 can use wear-resistant cast iron as the base body, and the elbow body 1 At least one section of the internally formed pipeline is an arc-shaped pipeline 2, and the elbow body 1 is provided with a groove 3 on the outer arc side of the section of the arc-shaped pipeline 2, which can be filled with and retain the material transported by the pipeline. Since the bent pipe body 1 of the embodiment of the present invention is provided with a groove 3 on the outer arc side of the arc-shaped pipe 2,...

Abstract

The invention discloses a self-filled elbow. The self-filled elbow comprises an elbow body (1), wherein at least one section of a pipeline formed in the elbow body (1) is an arc-shaped pipeline (2); and a groove (3) which can be filled and in which a material conveyed by the pipeline is retained is formed in the outer arc side of the arc-shaped pipeline (2) of the elbow body (1). Since the groovewhich can be filled and in which the material conveyed by the pipeline is retained is formed in the outer arc side of the arc-shaped pipeline of the elbow body, when the elbow conveys the material, the groove is self-filled with the material conveyed by the pipeline; the material in the groove can resist abrasion to and impact on the outer arc side of the arc-shaped pipeline when the pipeline conveys the material; the material in the groove can be continuously self-replenished; and therefore, the wear resistance of the outer arc side of the arc-shaped pipeline is improved, and the wear resistance and the impact resistance of all parts of the elbow are well balanced. The invention further discloses a pipeline conveying system including the self-filled elbow and a concrete pump.

Description

technical field [0001] The invention relates to an elbow used for material transportation, in particular to a self-filling elbow used for concrete delivery, and also relates to a pipeline delivery system and a concrete pump including the self-filling elbow. Background technique [0002] In many pipeline transportation systems, elbows are usually provided at the corners of the pipelines, and the outer arc side inside the elbows in the pipelines usually wears the fastest. For example, the most common bends of the pipeline conveying system on the boom of the pump truck are single-layer cast steel bends and composite bends. During the work of conveying concrete, the bend of the pipeline conveying system on the boom of the pump truck needs to bear Due to multiple forces such as concrete erosion and pressure fluctuation impact, the middle part of the outer arc inside the elbow is extremely worn. Among the elbow damage failure forms, the failure of the middle part accounts for as h...
