<p>A hanger device (50) and an annular cooler having same the hanger device (50) comprising a hanger fastener (51) and four connecting pieces (52 53 54 55) disposed in sequence from top to bottom; the upper end of the first connecting piece (52) is hinge connected to the hanger fastener (51); between the opposing ends of the second connecting piece (53) and the first connecting piece (52) is a first threaded fit; the opposing ends of the third connecting piece (54) and of the second connecting piece (53) are nested together and between the two opposing ends is allowed a vertical relative displacement with mating lower stop limiting units (E); between the opposing ends of the fourth connecting piece (55) and the third connecting piece (54) is a second threaded fit the lower end of the fourth connecting piece (55) being used to hinge connect to a gate type sealing device (60); and the sum of the vertical unscrewed lengths of the first threaded fit and the second threaded fit is greater than or equal to a vertical preset distance (L); the minimum vertical relative displacement between the third connecting piece (54) and the second connecting piece (53) enables both the first connecting piece (52) and the fourth connecting piece (55) to rotate around respective hinge points. The hanger device (50) has improved operability for installation and adjustment.</p> |
