A floating mechanism and an annular air duct end sealing device

Abstract

A floating mechanism is used to support the floating member. The floating mechanism includes at least three levers and radial pulley blocks with the same number as the levers. The three levers share a fulcrum, and the fulcrum is a cylinder; one end of each lever is applied with balance gravity, and the other end of each lever is provided with a first guide device that limits the movement of the pulley block along the axis of the lever. The fulcrum is fixedly installed on the workbench or track. The pulley block includes the same number of pulleys and pulley support mechanisms as the number of levers, and a second guide device for limiting the movement of the pulleys in the vertical direction. The pulley support mechanism includes a support body that moves along the second guide device, a guide block that is rigidly connected with one end of the support body and moves along the first guide device, and a guide block that is rigidly connected with the other end of the support body and is used to support the pulley. Pulley support. The invention also provides an end sealing device of the annular air duct, which is used to ensure the sealing of the end of the annular air duct.

Description

technical field [0001] The invention relates to a floating mechanism, in particular to a floating mechanism and an end sealing device of an annular air duct. Background technique [0002] The annular cooler generally uses air cooling to cool the material of the annular cooler trolley, but it does not need to be cooled in the unloading area of ​​the annular cooler trolley, and this area is called a non-cooling area. In order to ensure that the cold air does not leak in the non-cooling area, it is necessary to seal the end of the annular air duct. [0003] The double-layer trolley of the annular cooler is generally equipped with an annular air duct, and the cold air passing through the annular air duct cools the material of the annular cooler trolley. In order to ensure the cooling effect of the cooling zone and prevent the leakage of cold air, it is very important to seal the annular air duct. [0004] The existing better way to ensure air duct sealing is to adopt a liquid ...

AI Technical Summary

Problems solved by technology

[0006] Due to the installation and processing errors of the annular cooler, the door-type sealing device may have radial and axial displacements of the annular cooler. When the cover plate of the door-type sealing device produces radial deviation and axial displacement, the door-shaped The scratch between the sealing device cover plate and the baffle may even damage the baffle and drive the baffle to move together

As a result, the cold air enters the non-cooling area directly from the door-type sealing device, causing the liquid in the annular liquid tank to fluctuate and vibrate strongly
