Embodiment Construction

[0017] The lifting device of the present invention is used to lift and separate a large rotating part from the frame. Such as figure 1 As shown, the rotating member 10 is a drying cylinder for papermaking. The end 11 of the drying cylinder is provided with a bearing 12 , and the bearing 12 is accommodated in a bearing seat 13 , and the bearing seat 13 is then fixed on a frame 14 . Wherein the upper half of the bearing seat 13 is fixed with the upper beam 141 of the frame 14, and the lower half of the bearing seat 13 is fixed with the lower beam 142 of the frame 14. figure 1 The upper half of the bearing housing 13 shown in has been removed. When the bearing 12 needs to be replaced, the end 11 of the drying cylinder needs to be separated from the frame 14 to dismantle the lower half of the bearing seat 13 to replace the bearing 12. The existing method is to lift the end portion 11 of the drying cylinder and separate it from the frame 14 at a journal 16 of the end portion 11 ...

Abstract

A lifting device for lifting and separating the bearing seat of the rotating part from the frame, the rotating part has a journal, the frame has two upper and lower beams, the lifting device includes a connecting rod, a jack Mechanism, several support plates and fixing parts, the support plate is fixed on the lower beam by the fixing parts, the support plate is provided with perforations for the connecting rod to pass through, and the jacking mechanism is arranged on the connecting rod and is used to push the journal of the rotating part. The present invention directly exerts force on the frame of the rotating part by means of related structures such as a connecting rod, a jacking mechanism, a support plate, and a fixing part, so that the rotating part is separated from the frame. The lifting device has a simple structure and can be operated in a small operating space. Compared with traditional cranes and other equipment, the lifting device has higher working efficiency and lower cost.

Description

technical field [0001] The invention relates to a lifting device, in particular to a lifting device for lifting heavy equipment so as to facilitate the replacement of parts in the equipment. Background technique [0002] The drying cylinder is an important equipment in the paper machine. After the dryer bearings are worn or damaged during operation, they need to be replaced in order to keep the dryer running normally. When replacing a bearing, the bearing housing must be separated from the frame first, then the worn bearing must be disassembled on-machine, and then a new bearing must be installed. Because the drying cylinder is heavy, it needs to be hoisted with the help of a crane or a large hoist to separate the bearing seat from the frame. However, due to the special installation position of the drying cylinder, there is an oven cover or other rollers above it. In the actual operation process, these devices hinder the hoisting of the crane, resulting in time-consuming a...
