Problems solved by technology

3. Imported foreign bent pipe, the outer pipe is ordinary seamless steel pipe, the inner sleeve is made of die steel or high-speed steel inner bent pipe, this method has high wear resistance, easy to use, and quick replacement, but because there is no domestic manufacturer, the technology The points are all controlled in Germany, Japan and the United States, and the import price is higher, which increases the cost

Abstract

The invention discloses an inserted type high-wear-resistance composite integrated tail end elbow pipe for a concrete pump truck. The inserted type high-wear-resistance composite integrated tail end elbow pipe comprises an elbow pipe body, the side edge of the elbow pipe body is provided with a through hole, a high-alloy patch is inserted into the through hole, the outer side of the high-alloy patch is provided with a steel panel, and the steel panel is welded to the elbow pipe body. The inserted type high-wear-resistance composite integrated tail end elbow pipe has the characteristics of highstrength, high impact resistance, high wear resistance and the like, the wear-out period is prolonged by 6-8 times compared with other similar products, therefore the functions that the operation cost and materials are greatly reduced, and the replacement times are greatly lowered are achieved, the service life of the elbow pipe is prolonged, production efficiency is improved, and the functions of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an embedded high wear-resistant composite integrated end elbow for a concrete pump truck. Background technique [0002] At present, there are mainly the following types of delivery elbows for domestic concrete pump trucks (trailers and ground pumps): 1. General materials and single materials, such as seamless steel pipes that have been heated and retreated for a second time, and then manually welded to produce bends. Although the tube has a little strength and toughness, it has been basically eliminated because of its poor wear resistance, short service life and frequent replacement, which affects work efficiency and increases process costs. 2. Cast high-manganese steel pipe fittings are used to increase its wear resistance. Now the high-manganese steel elbow can increase the amount of concrete conveyed to 15,000 to 20,000 cubic meters on the basis of the first type...
