Description

Online quick change device of ladle roller is prevented to withdrawal and straightening machine

Technical Field

The utility model relates to the technical field of mechanical device, in particular to draw and rectify machine and prevent online quick change device of wooden dipper roller.

Background

The tension leveler has the functions of pre-descaling the strip steel and improving the plate shape, is an essential device in the cold rolling and acid rolling process, and has the use effect directly influencing the acid washing effect of hot rolled incoming materials.

The traditional roller changing operation is that the outer cover of the car pulling machine is firstly lifted out, the strip steel in the frame is broken and pulled out, constructors enter the frame to disassemble and lift the rollers, then the new rollers are lifted into the frame to be reloaded, the outer cover is reloaded, and finally, the strip steel needs to be reloaded into the frame by using a guide rope, so that time and labor are wasted. The outer cover is lifted and removed for one hour, the steel strip is broken and drawn for 1.5 hours, the roller is replaced by a constructor for 4 hours, the outer cover is re-installed for one hour, the steel strip is threaded for 1.5 hours again, the acid rolling line is a continuous unit, the steel strip connected with a leading rope after the steel strip is broken can be recovered to the normal rotation of the unit before a rolling mill which runs at an extremely slow speed, and the time is at least fifteen hours of maintenance.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the utility model aims at providing an online quick change device of ladle roller is prevented to withdrawal and straightening machine, concrete technical scheme is as follows:

an on-line quick change device for a ladle-proof roller of a withdrawal and straightening machine comprises a roller change trolley and a roller change tool;

the roll changing tool is composed of a steel bracket;

the two ends of the bracket are provided with mounting seats, the lower end of the bracket is provided with a sliding chute which runs through the mounting seats at the two ends, and the sliding chute can be matched with a trolley body pulley of the roll changing trolley for use;

eight groups of roller bearing blocks are arranged on the bracket and are uniformly distributed at the upper end of the bracket, and a radial stabilizing groove is arranged between each pair of bearing blocks;

a radial stabilizing groove with the same size as that between the bearing blocks is formed in the center of the mounting seat;

an oblique square is arranged between every two adjacent groups of bearing blocks and used for reducing the whole weight of the roll changing tool;

the end face of the bearing block is a roller bearing face, and the radial stabilizing groove is matched with the radius of the roller and is used for ensuring that the roller cannot overturn in the roller conveying process;

the mounting base on one side is arranged to be a traction side, and the traction side is connected with a rotating lead screw of the roll changing trolley;

all be equipped with the bolt hole on mount pad, carrier block, the radial stable trough for hoist and mount and later stage add the annex and use.

The preferred scheme of the on-line quick change device for the anti-ladle roller of the withdrawal and straightening machine is that the distance between the radial bearing blocks is 50 mm.

The preferable scheme of the on-line quick change device for the anti-ladle roller of the withdrawal and straightening machine is that the length of the roller change tool is 2600mm, and the height range is 1500mm-2200 mm.

The utility model provides a draw and rectify quick-witted on-line quick change device of ladle roller that prevents: a constructor enters the tension leveler rack to disassemble an old roller and moves a roller changing vehicle with a roller changing tool to a corresponding tension leveler rack position; pushing the special tool into the rack, dropping the old roller onto the roller changing tool by constructors, drawing out the roller changing tool, and operating according to the reverse step after the new roller is reloaded.

The utility model has the advantages that: the utility model discloses a roll change specialized tool is exactly through reforming transform the former roller case to drawing the roller to use with drawing the roller changing car of straightening machine, directly take out the anti-gourd ladle roller in the frame under the condition of not demolising the outer cover of drawing the straightening machine, realize the quick change ability, very big reduction the activity duration.

1) The special roll changing tool is manufactured and organically combined with the existing pulling and straightening roll changing vehicle, convenience and flexibility are achieved, and meanwhile, the manufacturing cost is low and can be ignored.

2) Compact structure, small occupied space and high construction efficiency.

3) The condition that the upper limit of the crown block needs to be adjusted in the past operation is avoided, and the accident potential is eliminated.

4) The construction work intensity is greatly reduced.

The special roll changing tool is used, belt breakage and outer cover hanging are not needed, the belt hanging and breaking and threading time is saved, the whole construction process can be completed only in six hours, 60% of time is saved, the machine installing amount of six anti-gourd-ladles rolls is calculated, the machine is changed once a year, the machine halt time is saved by 6 x 9 to 54 hours, the machine halt time is saved by rolling 300 tons of cold-rolled plates per hour, the price profit of each ton of steel is calculated by 0.02 ten thousand yuan, and the pure value of 54 x 300 x 0.02 to 324 ten thousand yuan can be created. Has excellent economical efficiency.
