DETAILED DESCRIPTION

[0017] The present invention will be further explained and illustrated below with reference to the accompanying drawings:

[0018] For example, see Figure 1-Figure 2 An auxiliary device for installing purlins on the exterior guard plates of a thermal power generator plant comprises a base frame 1, pillars 3 and a top frame 4. A limiting column 2 is arranged at the front end of the base frame 1, pillars 3 are respectively arranged on both sides of the rear end of the base frame 1, a top frame 4 is arranged on the top of the pillars 3, a lifting mechanism is arranged above the top frame 4, and a merging frame 6 is hinged at the front end of the top frame 4. The bottom of the merging frame 6 is located on the limiting column 2, and the bottom of the merging frame 6 is fixedly connected to the limiting column 2 by bolts 8.

[0019] A U-shaped frame 9 is provided on the back side of the support column 3 , and a guide wheel 10 is provided inside the U-shaped frame 9 .

[0020] The upper part of the front end of the limiting column 2 is an inclined surface, the merging frame 6 is tightly attached to the front end surface of the limiting column 2, and a material receiving box 7 is provided at the lower part of the front end of the limiting column 2.

[0021] The front end of the top frame 4 is located in the upper middle portion of the bottom frame 1 . A lifting lug 5 is provided on the top of the top frame 4 . The lifting lug 5 is connected to a lifting structure via a pull rope 18 .

[0022] There are two lifting mechanisms, and each lifting mechanism is composed of a top plate 11, a wire wheel 12, a winding frame 13 and a motor 14. The top plate 11 is distributed in an L shape. A wire wheel 12 is provided at the front end of the top plate 11, and a winding frame 13 is provided on the top of the top plate. A pull rope 18 is wound around the winding frame 13, and a motor 14 is provided on one side of the winding frame 13.
