After concrete has already reached to the maintenance term, you can draw ink lines of cables traveling central line, central lines of both earth shaft and installation on the terrace. At last, put every component in their right places. Set main shaft center of central rotary pay-off stand as a point and main shaft center of drum head stranding gearbox as another point. Then you can use steel wire (diameter is Φ1mm) to joint the two points together as a line .You can use turn buckle to pull it tight, and use heavy punch to make the small steel wire to stand in the same vertical face with ink line on the terrace. Together you can adopt a level instrument to calibrate central height mark of steel wire to be 1 meter. Then, you could adjust central height of all components according to it. Note: Attentions must be paid to that the circumferential gap of blind flange which was one end close to conduction device of main shaft of fork and stranding gearbox should be equivalent. It can be realized by adjusting devices of supporting wheel device. First make horizontal alignment of central height of fork stand. Then, with fork stand as the benchmark to adjust horizon of stranding gearbox.Finally, re-examining completely whether all sizes are equal to the requirements of the graphic. When correcting horizon and heights of installation, you must follow the working standard of TJ231.The allowable deviation of each component is ≤0.5mm.After examination, you are able to start second grouting. After about two-week’s maintenance, you should calibrate horizontal, vertical, central heights and sizes of the whole machine precisely. If any change occurs, it is permitted to add sizing block to the bottom of the machine, then fasten the anchor bolt.

Wire the connecting line according to the electrical wiring drawing. Jointing pneumatic and hydraulic pipelines and verifies the correctness of electric connection, no leakage in both of the pipelines. After installation and regulation, you ought to clean out the greasy dirt of every assembly especially the exterior surface of big bearing wheel and supporting wheel. Then inject the stated lubricant in lubricating point; checking the fastening pieces of every component to avoid looseness. Compressed air or other methods should be used to clean out sundries in every pneumatic and oil pipe, to prevent the sundries from entering into pneumatic, hydraulic devices.

After injecting hydraulic oil into every hydraulic box, start the oil pump motor, operate lifting and putting-down the oil cylinder time after time, making oil cylinder and pipeline full of oil and then filling the oil box with oil.

4.2 Trial run

You should trial run every component one by one. At the beginning, first check the firmness of them, let bobbin twisting head, caterpillar-tractor and taping device in free position, and let stranding gearbox in low-speed step. Start main motor slowly and gradually rise to max speed step by step. After ten-minute operation, then reduce the speed and stop the device. Then, let stranding gearbox rotate at intermediate speed and high speed respectively. Carry out the above trial run, let drum head rotate at low speed, intermediate speed and high speed separately and try for 20 minutes.

Add proper quantity of oil to rotary connection of caterpillar-traction (twisting off inlet connection of rotary connection individually) to reduce friction force between sealing ring and distribution connection. Adjusting compacting air pressure and tension pressure .Then join with caterpillar-traction, taping device, etc. and has trial run from low speed to high speed.

Next step is trial run of rotary pay-off stand then the trial runs of take-up device and traverse device.

During the trial run course, operating progressively form low speed to higher speed. Before running in high speed, checking fastening piece once again is suggested. If any abnormal situation appears, you should stop the machine to check in time. Continue trial run after clearing of the fault.Set fork stands of drum head and rotary pay-off stand at horizontal position respectively. And begin test run of clamping device and hydraulic lifting platform.

Start hydraulic system, make lifting platform rise or fall to the positions which are needed for lifting and putting down bobbins, and adjust position of each position switch.

Note: Overflow valve should be adjusted gradually from low level to higher level. It is proper for lifting platform to carry the bobbin filled with cables, and you should never adjust the overflow valve too low.

After finishing all the above trial run, next you can operate whole machine linked trial run, dry run for 2 hours from low speed to higher level. Both of its rotary pay-off stand and drum head should run for 40 minutes. There must be no abnormal sound. After the whole process, checking temperate rise of each bearing to make sure it is below 40℃. Test production can be started unless the dry run meets the criterion.


4.3 Operation

Before formal production, correctness, safety and reliability of interlocking mechanism of all running components must be checked. Follow the technology requirements to outfit needed wire mould; to place bobbins of every pay-off stand; to fix belting reel; to pull gear change hand level to required steps; to adjust traverse pitch adjuster knob to suitable place. Install Ф3150 take-up bobbin after adjusting the right tension of take-up motor according to the wire width.

After bobbins have been fixed onФ2250 rotating pay-off stand, pay-off tension of each bobbin should be adjusted properly and uniformly, bobbin must be pulled tightly and the retaining mechanism should be reliable enough. Letting discharging cable core wire pass the guiding stand then via assembly die carrier to assemble them together ,and linked with advanced prepared leading wire (Leading wire pass through tapping head, caterpillar capstan, conduction device , stranding gearbox and traverse stand to wind on the take-up bobbin). Then jogging to start the machine, adjusting the tapping tension, entrance angle, pitch and traverse pitch, etc. to suitable level. Machine can be run after wires winding on take-up bobbin.

After cables reach to the required length, stop the machine and jog to set fork stand to horizontal situation and plug the bolt into brake wheel, start bridge crane to hold take-up bobbin, power-on clamping motor. Turn the pulling rod and releasing bobbins, bridge crane rise to ground; rolling out the bobbin and be installed in the empty bobbin.

Note: After bobbins are clamped by pintles, clamping motor ought to be closed or it is easily to damage driving mediums like the clamping motor. Withdraw the horizontal bolt and wind cables around the empty bobbin. When all these works is done, formal star-up is allowed.(The course of rotating pay off stand loading and unload is same of the kind mentioned )

Attention: Line-start should be slow. Normal stop should be slow, the speed should be reduced, too.
