Abstract

The invention discloses a prefabricating tool for a triple connecting pipe of a heat collecting pipe of a trough type photo-thermal power station. The prefabricating tool comprises a welding positioner and a plurality of adjustable lifting rolling tables, the welding positioner is located at one end of the triple connecting pipe of the heat collecting pipe, a clamping jaw of the welding positioner is in close contact with the surface of an inner pipe at the end of the triple connecting pipe of the heat collecting pipe, and the bottom of the welding positioner is fixed to the horizontal ground through foundation bolts. The adjustable lifting rolling tables and the welding positioner are installed on the same axis of the same horizontal plane, a distance is formed between every two adjacent adjustable lifting rolling tables, and each adjustable lifting rolling table makes contact with the surface of the triple connecting pipe of the heat collecting pipe so as to support the triple connecting pipe of the heat collecting pipe. The number of the adjustable lifting rolling tables is six. According to the prefabricating tool for the triple connecting pipe of the heat collecting pipe of the trough type photo-thermal power station, rapid prefabrication and welding of the triple connecting pipe of the heat collecting pipe are facilitated, the welding quality of the heat collecting pipe is guaranteed, finished product protection of the triple connecting pipe of the heat collecting pipe is facilitated, and the straightness requirement of the triple connecting pipe of the heat collecting pipe is guaranteed.

Description

technical field [0001] The invention relates to a prefabricated tooling for three-connected heat collecting tubes of a trough photothermal power station, which belongs to the technical field of photothermal power generation. Background technique [0002] The solar heat collection field is composed of several heat collection circuits: each heat collection circuit is composed of four 150-meter-long collector assemblies (SCA); each SCA is composed of twelve 12-meter-long collector units SCE connected; Each SCE contains 3 collector tubes. [0003] There are 144 heat collector tubes in each circuit. Before the heat collector tubes are installed on the SCE array, they are prefabricated and welded into three tubes. The outer diameter of the glass tube cover of the heat collecting tube is 125mm, the length of the metal heat absorbing tube is 4060mm, the material is TP321, and the specification is 70*2.2mm. [0004] The heat collecting tubes are fragile and require a large amount o...
