Embodiment Construction

[0031] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] Such as Figure 8 to Figure 9 As shown, according to the embodiment of the present invention, the manufacturing method of the long cantilever conveying pipe comprises: selecting the cantilever conveying pipe made of the wear-resistant pipe quenched on the inner wall as the cantilever conveying pipe to be welded; A solder groove is opened on the inner wall of the welding end, and wear-resistant solder is piled up in the solder groove; the two cantilever section delivery pipes to be connected are butt-jointed, and then grooved butt welding is performed.

[0033] Through the above method, when using the wear-resistant pipe quenched on the inner wall as the long cantilever conveying pipe, the two...

Abstract

The invention provides a long cantilever delivery pipe and a manufacturing method thereof. The manufacturing method includes: making a wear-resisting pipe, with the inner wall quenched, into cantilever delivery pipes used as cantilever delivery pipes to be welded; making a flux groove in the inner wall of the welding end of each cantilever delivery pipe to be welded, and stacking wear-resisting flux in the flux grooves; butt-connecting the two cantilever delivery pipes to be connected, and making grooves and connecting by butt welding. Through the application of the manufacturing method, the problem that the wear-resisting pipe with the inner wall quenched cannot be used as the cantilever delivery pipe in the prior art can be solved.

Description

technical field [0001] The invention relates to long cantilever material conveying equipment, in particular to a long cantilever conveying pipe and a manufacturing method thereof. Background technique [0002] With the rapid development of China's construction industry, the construction party's requirements for the size and length of pipe piles are diversified, resulting in an overall requirement for concrete delivery pipes for pipe pile manufacturing equipment to be longer and longer. For the pipe pile manufacturing equipment that generally uses cantilever pipe layout, the longer the cantilever, the greater the increase in the mass of the conveying pipe and concrete, and the greater the bending moment; the increase of the bending moment not only increases the bending of the cantilever pipe, but also increases the The interference of the mold will affect the production efficiency, and it is easy to bend and break, causing production accidents. [0003] as attached Figure 1...
