Abstract
The present invention relates to a kind of construction method of the board-like vertical miller power transmission shaft of utilization suspender quick-replaceable, it is characterized in that：Alignment is carried out at cross bag using the crane in factory building by special hoisting appliance to vertical miller power transmission shaft carry extension, locked with safety lock, by vertical miller power transmission shaft, level is removed between edger roll and driving motor, it is placed on power transmission shaft storage stand, returns dress process opposite with unloading process step.Its advantage is：Vertical miller power transmission shaft is changed using the hoisting appliance of special design, the technical barrier of vertical miller power transmission shaft lifting is solved, it is simple to operate safe, time saving and energy saving, change vertical miller power transmission shaft efficiency high.
Description
Technical field
The present invention relates to a kind of construction method of the board-like vertical miller power transmission shaft of utilization suspender quick-replaceable, belong to
Metallurgical machinery equipment installation field.
Background technology
2250 vertical miller power transmission shafts of iron and steel enterprise are the attachment means between edger roll and driving motor, can
Vertical roll of rolling is set to run well.The installation site of power transmission shaft is on the inside of rolling-mill housing, and two ends are connected to
Motor side and vertical roller side, blending bolt fastening.The torsion occurred in the process of running because power transmission shaft is long
Greatly, it is the important component of vertical miller equipment.
The roughing mill of 2250 continuous rolling production lines plays the cogging effect of slab in process of production, in production process
The middle damage for producing great torsion to easily cause power transmission shaft, the quality of vertical miller cogging directly affects finished product
The quality of plate, more influence sale.So to regularly replace the power transmission shaft of vertical miller.General replacing options
It is：Both sides rational position sets two 10t jacks in frame, after then being removed using jack,
Step by step have bad luck the position that factory building crane can be lifted directly with stupid power, entered using the crane in factory building
Row handling.When vertical miller power transmission shaft returns dress, then using the inverted order method of the above method.This process
The cycle for completing dismounting and installing is more long, it is necessary to more manpower and materials.
The content of the invention
It is an object of the invention to provide a kind of safe, time saving and energy saving utilization suspender quick-changing plate simple to operate
The construction method of formula vertical miller power transmission shaft.
Technical scheme uses following steps：
1) the actual confined space of the actual measurement vertical miller power transmission shaft installation site in scene in rolling-mill housing,
And determine distance and crane eave tile at the top of Hoisting Position and milling train to lifting according to the own wt of power transmission shaft
Hang the distance of position；
2) hoisting appliance is made according to actual measured results, hoisting appliance is frame-shaped construction, by Top Crossbeam, is stood
Arm, lower cross arm are linked in sequence composition, and suspender ring is provided with Top Crossbeam, and U-shaped is provided with the end of lower cross arm
Lifting draw-in groove, the port of U-shaped lifting draw-in groove is provided with safety lock；
3) suspender is sling in the position of lifting point using the crane in factory building, then in jenny to frame
Lifted with U-shaped at the cross bag of vertical miller power transmission shaft is carried out at cross bag of the draw-in groove to vertical miller power transmission shaft
Alignment carries extension, is locked with safety lock；
4) bolt of transmission shaft connection place is removed, with crane and suspender by vertical miller power transmission shaft is from edger roll and passes
Level is removed between dynamic motor, is placed on power transmission shaft storage stand；
5) will need the vertical miller power transmission shaft for more renewing is carried out carrying padlock with suspender on stand and determines；
6) new vertical miller power transmission shaft is carried out into back dress, returns dress process opposite with unloading process step.
It is an advantage of the invention that：Vertical miller power transmission shaft is changed using the hoisting appliance of special design, is solved
The technical barrier of vertical miller power transmission shaft lifting, it is simple to operate safe, time saving and energy saving, change vertical miller and pass
Moving axis efficiency high.
Brief description of the drawings
Fig. 1 is the structural representation of hoisting appliance；
Fig. 2 is the A portions partial enlarged drawing of Fig. 1.
Specific embodiment
Embodiment：
Board-like vertical miller power transmission shaft on 2250 continuous rolling production lines of certain sheet material company is changed, specifically
Step is as follows：
1) the actual confined space of the actual measurement vertical miller power transmission shaft installation site in scene in rolling-mill housing,
And determine distance and crane eave tile at the top of Hoisting Position and milling train to lifting according to the own wt of power transmission shaft
Hang the distance of position；
2) hoisting appliance is made according to actual measured results, as shown in drawings, hoisting appliance is frame-shaped construction,
It is linked in sequence and is constituted by Top Crossbeam 1, armstand 2, lower cross arm 3, suspender ring 4 is provided with Top Crossbeam, under
The end of transverse arm is provided with U-shaped lifting draw-in groove 6, and the port of U-shaped lifting draw-in groove is provided with safety lock 5；
3) suspender is sling in the position of lifting point using the crane in factory building, then in jenny to frame
Lifted with U-shaped at the cross bag of vertical miller power transmission shaft is carried out at cross bag of the draw-in groove to vertical miller power transmission shaft
Alignment carries extension, is locked with safety lock；
4) bolt of transmission shaft connection place is removed, with crane and suspender by vertical miller power transmission shaft is from edger roll and passes
Level is removed between dynamic motor, is placed on power transmission shaft storage stand；
5) will need the vertical miller power transmission shaft for more renewing is carried out carrying padlock with suspender on stand and determines；
6) new vertical miller power transmission shaft is carried out into back dress, returns dress process opposite with unloading process step.
Only complete the replacing task of vertical miller power transmission shaft with 8 hours using above-mentioned steps, Billy is with falling
Chain carries out stupid power replacing and has saved 12 hours.
