Embodiment Construction

[0040] The core of the present invention is to provide a hanger device for hoisting the door-shaped sealing device on the support beam of the trolley, which can effectively use the screw thread to adjust the overall length to meet the assembly requirements of the door-shaped sealing device. The advantages of operation; at the same time, it provides an effective guarantee for improving operation safety.

[0041] Without loss of generality, this embodiment will be described in detail below in conjunction with the accompanying drawings.

[0042] The orientation words involved in this article, such as upper and lower, are defined based on the use status of the annular cooler. It should be understood that the use of the above orientation words, such as upper and lower, does not limit the scope of protection claimed in this application.

[0043] The annular cooler described in this embodiment is roughly divided into high-temperature zone I, medium-temperature zone II, low-temperatur...

Abstract

The invention discloses a lifting frame device, comprising a lifting frame fixing member and four connecting members arranged from top to bottom in sequence; the upper end of the first connecting member is articulated with the lifting frame fixing member; opposite ends of the second connecting member and the first connecting member are in first screw-thread fit; opposite ends of the third connecting member and the second connecting member are nested, and the third connecting member and the second connecting member can undergo vertical relative displacement and are provided with matched lower stopping and limiting parts; opposite ends of the fourth connecting member and the third connecting member are in second screw-thread fit, and the lower end of the fourth connecting member is articulated with a gate-type sealing device; and the sum of vertical screw-out lengths of the first screw-thread fit and the second screw-thread fit is more than or equal to a predetermined vertical distance,and minimum vertical relative displacement between the third connecting member and the second connecting member meets a condition that both the first connecting member and the fourth connecting member can rotate around respect articulation points. The lifting frame device disclosed by the invention ahs the advantages of better operability and safety. Based on the lifting frame device, the invention further provides a circular cooler with the lifting frame device.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to a ring cooler and a hanger device for a door-type sealing device thereof. Background technique [0002] Annular coolers are used in iron and steel enterprises to cool sintered high-temperature materials. The annular cooler has a circular shape as a whole, and is divided into a cooling zone and a non-cooling zone along the circumference. During the operation, the ore to be cooled is poured into each ring cooler trolley from the charging station in the non-cooling area, and after entering the cooling area, the ore is cooled by the pressure wind, and then each ring cooler trolley enters the non-cooling machine. The unloading station in the area completes cooling and unloading. [0003] See figure 1 and figure 2 ,in, figure 1 is a schematic diagram of the overall structure of the ring cooler, figure 2 for figure 1 A-A partial sectional view of the annular cooler shown....
