Abstract

The utility model discloses a balance lifting appliance for replacing a bearing seat of a drying roller, which comprises a balance supporting base, wherein a balance lifting beam is fixedly arranged on the upper surface of the balance supporting base, a first lifting lug is arranged at the center of the surface of the balance lifting beam, and a second lifting lug and a third lifting lug are symmetrically arranged at the two ends of the surface of the balance lifting beam; the mirror image on the balance support base at the two ends of the balance hanging beam is fixedly provided with a bearing seat fixing plate, and a bearing seat fixing bolt is arranged on the bearing seat fixing plate. The lifting appliance has the characteristic of bidirectional balance, replaces the traditional working mode of manually pulling, pushing and lifting, saves time and labor, can finish the disassembly of an old bearing seat and the assembly of a new bearing seat in one-time lifting work, reduces the lifting frequency and greatly improves the working efficiency.

Description

Balance lifting appliance for replacing bearing seat of drying roller

Technical Field

The utility model relates to a metallurgical steel rolling lifting device field, concretely relates to balanced hoist for wringing roller bearing seat is changed.

Background

The squeeze roll in the cold rolling process of a carbon steel sheet plant is frequently replaced, about 260 rolls need to be replaced every year, the squeeze roll needs to be replaced by dismounting and mounting the bearing seat damaged by the non-transmission side every time, each bearing seat weighs about 60 kg, the bearing seat on the non-transmission side is embedded into the equipment rack, and vertical hoisting cannot be realized, so that the bearing seat is usually matched by using a crown block when being replaced on an operation site, the bearing seat is hoisted and transported to the position near the equipment rack, and then the bearing seat is pulled, pushed, lifted and dismounted by manpower, so that the working strength is high, and if the bearing seat is lifted unstably, the potential safety hazard that people are injured by sliding of the bearing seat exists.

SUMMERY OF THE UTILITY MODEL

The utility model provides a balanced hoist for change of wringing roller bearing frame, aim at solve the unable vertical hoisting of the inside bearing frame of embedding frame, and intensity is changed great to the manpower, and a large amount of replacement work is consuming time power not only, has the problem that the people potential safety hazard is hindered to the bearing frame landing moreover.

The utility model relates to a balance sling for replacing a bearing seat of a drying roller, which comprises a balance supporting base, wherein a balance hanging beam is fixedly arranged on the upper surface of the balance supporting base, a first lifting lug is arranged at the center of the surface of the balance hanging beam, and a second lifting lug and a third lifting lug are symmetrically arranged at the two ends of the surface of the balance hanging beam; and a bearing seat fixing plate is fixedly arranged on the balance support base at the two ends of the balance hanging beam in a mirror image manner, and a bearing seat fixing bolt is arranged on the bearing seat fixing plate.

Preferably, the two ends of the balance support base are provided with auxiliary handles.

Preferably, the first lifting lug, the second lifting lug and the third lifting lug are on the same horizontal line.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model provides a balanced hoist for change of wringing roller bearing frame, can fix new bearing frame in hoist one end earlier when changing, reuse overhead traveling crane cooperation chain block is hung in the balanced lug department of new bearing frame fixed position with the shackle, with its handling to change the position, then hang overhead traveling crane chain block in middle lug department with the shackle, fix old bearing frame in opposite side bearing frame fixed plate department simultaneously, handling tool has the characteristics of two-way balance, balanced operation hoist dismantles, at last with the rotatory 180 new bearing frames of the dress of balanced hoist, accomplish the change of embedding frame inside bearing frame, this hoist has replaced the tradition and has needed the manual work to draw, push up, lift the working method of dismouting, time saving and labor saving, and can accomplish the dismantlement of old bearing frame and the installation of new bearing frame in a handling work, the handling frequency has been reduced, the work efficiency is greatly improved.

2. The utility model provides a balanced hoist for change of wringing roller bearing frame, balanced support base both ends are equipped with auxiliary handle, the potential safety hazard that direct contact bearing frame brought when having avoided personnel's operation, and supplementary dismouting is more convenient.

3. The utility model provides a balanced hoist for change of wringing roller bearing frame can be customized according to different bearing frame models, simple structure, convenient operation, economical and practical.

Drawings

Fig. 1 is a schematic view of the overall structure of the balance spreader of the present invention;

in the figure: 1-a balanced support base; 2-balance hanging beam; 3-a first lifting lug; 4-a second lifting lug; 5-a third lifting lug; 6-bearing seat fixing plate; 7-bearing block fixing bolts; 8-an auxiliary handle; 9-bearing seat.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, the utility model relates to a balanced hoist for wringing roller bearing frame is changed, including balanced support base 1, balanced support base 1 both ends are equipped with auxiliary handle 8, and balanced support base 1 upper surface has set firmly balanced hanging beam 2, and 2 face center departments of balanced hanging beam are equipped with first lug 3, and 2 face both ends symmetries of balanced hanging beam are equipped with second lug 4 and third lug 5, and first lug 3, second lug 4, third lug 5 are in on the same water flat line. A bearing seat fixing plate 6 is fixedly arranged on the balance supporting base 1 at two ends of the balance hanging beam 2 in a mirror image manner, and a bearing seat fixing bolt 7 is arranged on the bearing seat fixing plate 6.

When changing the bearing frame, can fix the 6 left ends at the bearing fixed plate of hoist one end earlier with new bearing frame through bearing frame fixing bolt 7, reuse overhead traveling crane cooperation for the chain block break out hang in the second lug 4 department of new bearing frame fixed position, with its handling to change the position, then hang overhead traveling crane for the chain block break out in first lug 3 department, fix old bearing frame at the 6 right-hand members of bearing frame fixed plate through bearing frame fixing bolt 7 simultaneously, the handling instrument has the characteristics of two-way balance, the balanced operation hoist is dismantled, at last with the rotatory 180 new bearing frames of the dress of balanced hoist, accomplish the change work of the inside bearing frame of embedding frame.
