A u-support fixing device for a pipe expander

Abstract

The invention discloses a U-shaped support fixing device. The U-shaped support fixing device comprises an installing base and U-shaped supports; the installing base has more than two installing areas which are arranged in parallel; the U-shaped supports are arranged on the installing base; the U-shaped supports have more than two types, and more than two types of the U-shaped supports correspond to the installing areas one to one. According to the U-shaped support fixing device of a pipe expander, when a certain type of heat exchange equipment is fixed, the installing area of the corresponding type of the U-shaped support and the heat exchange equipment are correspondingly arranged, and a finned tube of the heat exchange equipment is fixed with the U-shaped support of the installing area; more than two installing areas can correspond to more than two types of the heat exchange equipment. Accordingly, the finned tubes of more than two types of the heat exchange equipment can be fixed, and the mode that in the prior art, a U-shaped support fixing base is replaced is not needed; the U-shaped support fixing device can adapt to more types of the heat exchange equipment, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to a U bracket fixing device, in particular to a U bracket fixing device of a tube expander. Background technique [0002] When the tube expander expands the finned tubes in the heat exchange equipment, the finned tubes need to be auxiliary fixed by the U bracket of the U bracket fixing device. The spacing and number of finned tubes of different types of heat exchange equipment are different, and corresponding types of U brackets are required for clamping and fixing. Therefore, different types of heat exchange equipment need to use corresponding U bracket fixing devices for heat exchange equipment. to fix. Currently, before the tube expander expands the finned tubes of different types of heat exchange equipment, the U bracket fixing device of the tube expander is replaced with the U bracket fixing device corresponding to the heat exchange equipment, and the U bracket fixing device The replacement operation is inconvenient, time-...
