Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present embodiment provides a movable heat exchanger overhauls hoist and mount frame of falling chain, including ejector pin 1 that the level set up, ejector pin 1 rear end downside symmetry sets up two inclined support pole 2, and the contained angle of two inclined support pole 2 and vertical face is the same, connects horizontal anchor strut 3 between 2 front side middle parts of two inclined support pole, connects inclined anchor strut 4 between 3 middle parts of horizontal anchor strut and the anterior downside of ejector pin 1, and 2 bottom homonymy levels of inclined support pole set up positioning bolt 5, and positioning bolt 5 front portion homonymy threaded connection fixation nut 6, the ejector pin 1 front end sets up riser 7, and the riser 7 lower part sets up the hanging hole 8 that hangs the falling chain.
In this embodiment, ejector pin 1, inclined support rod 2, horizontal strengthening rod 3, inclined strengthening rod 4 all adopt the channel-section steel.
In this embodiment, the connection modes of the ejector rod 1 and the inclined support rod 2, the ejector rod 1 and the inclined reinforcing rod 4, the inclined reinforcing rod 4 and the horizontal reinforcing rod 3, and the horizontal reinforcing rod 3 and the inclined support rod 2 are all welded.
