Abstract

The utility model relates to a lifting tool for replacing a drying roller and belongs to the technical field of mechanical equipment in metallurgy industry. The technical scheme is as follows: the sling comprises a primary lifting hook (1), a secondary lifting hook (2), a drying roller fixing sleeve (4) and an angular bracket (5), wherein the primary lifting hook and the secondary lifting hook are fixed on one side of the angular bracket, and the drying roller fixing sleeve is fixed on the other side of the angular bracket. The primary lifting hook and the secondary lifting hook are lifted by a crown block, when a part at which the drying roller is required to be replaced is reached, a spindle head protecting jacket is detached, one end of the drying roller is fixed by the drying roller fixing sleeve, after bearing blocks at two ends are detached, the crown block is operated to withdraw an old roller to a specific position, and a novel roller is lifted to be arranged in a groove. The lifting tool provided by the utility model has the advantages that the time of replacing the drying roller is greatly shortened, and the labor intensity of a maintenance worker is reduced; and moreover, the lifting tool has the characteristics of simple structure and convenience in operation.

Description

A kind of replacing squeeze roll suspender
Technical field
The utility model relates to a kind of lifting device of changing squeeze roll, belongs to the metallurgy industry mechanical equipment technical field.
Background technology
The cold-rolling pickling unit is changed squeeze roll and is all adopted squeeze roll replacing special cart both at home and abroad at present.The roll change process is following: ⑴, dolly is placed on the squeeze roll fore side platform track, and the plug that plugs in, energized promotes to select the squeeze roll of required replacing through motor; ⑵ go forward to enter the squeeze roll place through the movable motor driving trolley at its this track body; ⑶ drive jacking system through lifting motor and be elevated to the squeeze roll height, and then advance through movable motor and to make tentatively fixedly squeeze roll spindle nose of changing rig; ⑷ suppress locking squeeze roll spindle nose through the hydraulic locking jack on the changing rig; ⑸ dismounting squeeze roll bearing seat; ⑹ retreat through the movable motor driving trolley squeeze roll extracted out in acid tank, also will regulate jacking system as the case may be simultaneously; ⑺ fall after extracting old roller out, with overhead traveling crane old squeeze roll hung away, newer roller is placed on the dolly.Through reverse procedure new roller is installed again.When changing other squeeze roll, even also to the roll change buggy handling be carried out to corresponding platform.Changing squeeze roll through roll change buggy wastes time and energy, and changing 1 pair of squeeze roll needed about 2-3 hour, and influence is produced, and increases labor strength.
The utility model content
The utility model purpose provides a kind of replacing squeeze roll suspender, and is simple in structure, easy to operate, saves the squeeze roll time of changing, and reduces the labour intensity of service worker.Solve the problems referred to above that exist in the background technology.
The technical scheme of the utility model is: changes the squeeze roll suspender, comprises main suspension hook, secondary suspension hook, squeeze roll fixed sleeving, angle support, and fixing main suspension hook and secondary suspension hook on the limit of angle support, another side is the squeeze roll fixed sleeving fixedly
Be handled easily personnel's operation, the squeeze roll fixed sleeving is fixed on angle support end on one side, goes back fixed armrest on this limit.
Hang main hook with overhead traveling crane and hang with auxiliary hook and hang,, take squeeze roll spindle nose protecting sleeve apart to required replacing squeeze roll position; Fix squeeze roll one end with the squeeze roll fixed sleeving; Dismantled the two end axles bearing, just operation crown block is extracted old roller out and is placed on assigned address, and the new roller of slinging is then packed in the groove.
The beneficial effect of the utility model is: save the squeeze roll time of changing greatly, reduce the labour intensity of service worker.Have characteristics simple in structure, easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. main suspension hook, 2. secondary suspension hook, 3. handrail, 4. squeeze roll fixed sleeving, 5. angle support.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
With reference to accompanying drawing 1; Change the squeeze roll suspender; Comprise main suspension hook 1, secondary suspension hook 2, handrail 3, squeeze roll fixed sleeving 4, angle support 5, the angle support is a right angle rack, fixing respectively main suspension hook in two ends and secondary suspension hook on the limit of angle support; The end of another side is the squeeze roll fixed sleeving fixedly, goes back fixed armrest on this limit.Hang main hook with overhead traveling crane and hang with auxiliary hook and hang,, take squeeze roll spindle nose protecting sleeve apart to required replacing squeeze roll position; Fix squeeze roll one end with the squeeze roll fixed sleeving; Dismantled the two end axles bearing, just operation crown block is extracted old roller out and is placed on assigned address, and the new roller of slinging is then packed in the groove; This process simply saves time, and changes a pair of squeeze roll and only needs 40 minutes.
