Description

Convenient 350 short stress bracket device of flexible adjustment

Technical Field

The utility model relates to an operation technical field is changed in the adjustment of spiale on the bracket, especially relates to a convenient 350 short stress bracket device of flexible adjustment.

Background

When producing hot rolled steel twisted steel, what the finish rolling region adopted is 350 short stress rolling mill trains, and the rolling mill trains comprises rolling mill assembly, bracket assembly, spiale assembly, sideslip device, locking cylinder assembly, reduction gear assembly and direct current motor, and this patent relates to bracket assembly and spiale assembly two parts in this train, and the spiale assembly is installed on the bracket assembly, and the bracket is the device that is used for adjusting fixed spiale.

The current spindle adjustment and replacement procedures are as follows:

(1) adjusting a spindle: the equipment maintainer utilizes the adjustable wrench to rotate the adjusting nut on the 350 bracket, the screw thread on the nut drives the pull rod to move up and down, the pull rod is connected with the connecting shaft bearing position through the connecting rod and the sliding block, the adjusting nut can change the relative position of the two connecting shafts, and finally the positions of the two connecting shafts are adjusted.

(2) And (3) replacing a connecting shaft: when the equipment personnel change the operation of single spiale, the overhead traveling crane hoists the spiale, need demolish bracket clamp plate upper portion bolt earlier, loosen clamp plate lower part bolt, strike the clamp plate to the outside with the hand hammer, take out the slider, hang out the spiale, and the repacking process is opposite with above-mentioned process. When the upper connecting shaft and the lower connecting shaft are replaced by an operator, the overhead travelling crane hangs the connecting shafts, the bolts on the pressing plates need to be firstly removed, the pressing plates need to be removed, the sliding blocks need to be removed, and the upper connecting shaft and the lower connecting shaft need to be hung out. In the process of reloading, the bracket pressing plate needs to be recovered by a plurality of persons for cooperative work.

The adjusting mode of the connecting shaft is thread rigidity adjustment, in actual operation, the tightness of the pull rod can be adjusted only according to experience, due to high-speed operation, vibration generated by a rolling mill can be transmitted to the bracket adjusting nut through the connecting shaft, the vibration can cause the adjusting nut to be loosened, and the phenomenon that the connecting shaft cannot be adjusted in place exists. The field devices are more, and the personnel can have the phenomenon of untimely adjustment. The adverse results were as follows:

1. causing damage to the spiale bearing;

2. causing the flat head of the connecting shaft to be worn;

3. causing the shortening of the service life of the rolling mill roller bearing and the occurrence of cracks;

4. resulting in a shortened useful life of the bracket.

The disadvantages of this spindle replacement are as follows:

1. people participate more than 3 people;

2. the replacement time is long, about 40 minutes;

3. when the upper connecting shaft and the lower connecting shaft are replaced, the pressing plate for fixing the upper connecting shaft and the lower connecting shaft by the bracket is the same, so that the pressing plate is difficult to reassemble when the pressing plate is reassembled.

The invention realizes the innovative design, avoids the problems, realizes the adjustment of the position of the connecting shaft at any time, avoids the operation error of personnel, has less personnel participation during the operation of replacing the connecting shaft, improves the utilization rate of the personnel, improves the replacing speed, reduces the time delayed by the replacement and maintenance of equipment and realizes the improvement of the productivity.
