Hoisting and adjusting tool for cross door gas lock of discharging device

Abstract

The invention discloses a hoisting and adjusting tool for a cross door gas lock of a discharging device. One end of a hoisting frame of the hoisting and adjusting tool is fixed to a cross door shell,and a stretching-out portion at the other end and one end of a first lead screw are assembled through an adjusting screw; a freedom degree is formed between the first lead screw and the hoisting frame, and the adjusting screw rotates and makes the first lead screw move up and down; two lead screws are adjusted and connected through an adjusting lead screw support; and a hoisting ring is connectedto the lower end of a second lead screw, and is sleeved with a cross door gas lock shaft. According to the tool, after a cross door is fast supported and fixed by the tool, at least three maintainersand more than 180 min maintaining time are needed for the original disassembling and assembling process, only one maintainer and 30 min maintaining time are needed now, and the defect that the disassembling space is narrow can also be overcome.

Description

technical field [0001] The invention relates to a tool for hoisting and adjusting an air lock of a blanking cross door in wind power conveying equipment, in particular to the hoisting and adjusting of a cross door air lock of a tangential blanking device in production equipment for threshing and redrying. Background technique [0002] In the production equipment for threshing and redrying, the cross-door airlock bearing of the feeder of the threshing line air sub-machine is in a built-in closed environment with large dust, high wind speed (>25m / s), and high temperature (up to about 50°C) Among them, the oil seal of the cross door bearing is easy to cause aging deformation and lose its effect, and needs to be replaced; and the gap between the cross door air lock canvas rubber seal is worn and the gap increases, which will cause the air lock to leak, and the air distribution and air delivery system will cross each other, reducing the leaf blowing wind Subsystem efficiency. ...

Problems solved by technology

[0002] In the production equipment for threshing and redrying, the cross-door airlock bearing of the feeder of the threshing line air sub-machine is in a built-in closed environment with large dust, high wind speed (>25m / s), and high temperature (up to about 50°C) Among them, the oil seal of the cross door bearing is easy to cause aging deformation and lose its effect, and needs to be replaced; and the gap between the cross door air lock canvas rubber seal is worn and the gap increases, which will cause the air lock to leak, and the air distribution and air delivery system will cross each other, reducing the leaf blowing wind subsystem efficiency

[0003] There are 34 sets of tangential feeders in the beating line of the rebaking workshop. The cross door air locks have the same shape, diameter and size, and the average weight is 100kg; the cross door bearing and canvas rubber are built-in installation, and the cross door bearing must be removed first. And the supporting frame, the canvas rubber can only be replaced after taking out the cross door; since there is no special tool, the disassembly space is small, and each replacement of the cross door bearing or the cross door canvas rubber requires at least three maintenance personnel and more than 180 minutes of maintenance time
