Screw hoist the iron gate installation and commissioning and use of maintenance (a) a gate installation, before installation, to first check between mullions and horizontal frame, between the gate and the gate (gate finger multi-block combined gate) of the screw connection, is causing looseness in transport loading and unloading, their Stem whether the wrong tooth, to be adjusted to a gap plane, checking the shutter and the gate groove, the groove and the shutter gates ensure that the gap is not greater than 0.08mm if the gap can be adjusted Bijin devices. Tighten all bolts. 2. When installing the gate into the reserve overall vertical grooves on both sides stand in the box below to adjust the pad mat (mat prohibited under the crossbar), two vertical frame hoist and stayed with a firm hand, the gate looking straight leveling feet around the hole string bolt on, adjust the position of the gate good, support a good template pouring II. 3, pouring concrete, flowing into the gate, sluice boxes, wedges, mortar between the baffle should be thoroughly cleared to prevent the mortar Solidified gate opening and closing. 4. Clear reinforcements. Before the factory gates, for the gate, the gate frame fit compact, reducing the gap after installation, 2m above the gates are installed on the upper and lower frame 4-6 closed system pressure iron, attention after clearance adjustment, pressing iron Bijin demolition to open and close the gate. (B) the use of maintenance a gate, the gate should be noted on the gate, the lower limit position, not overrun, so as not to damage the gate or hoist. 2, in the starting gate closed during any abnormal situation should immediately stop using and timely inspection repair. 3, the gate in the closed end 10 centimeters away from the gate, suspended two minutes, rinse the bottom of the door so that the tank debris torrent, then the gates are closed. 4, to remove dirt and brake box on the gate when the gate is closed long before the emergency, after you have cleared the re-painted with new oil to prevent corrosion affect future hoist. (C) screw hoist one, be sure to keep the plane level basic layout 180o; hoist the base and foundation furnished flat contact area to reach more than 90%; screw axis to be perpendicular to the horizontal plane of the gate stage measure; to the gate plate lug holes and vertical text, avoiding screw tilt, causing local stress and mechanical damage. 2, the hoist into the installation location. Put a limit on the disk set screw, the screw is screwed into the beam from the lower hoist, hoist when the screw from the top of the machine is exposed, then put the stopper plate. Beneath the gate of the screw connection. 3, the basic building hoist installation must be firm and safe. Base and concrete foundation member, according to the provisions drawings pouring concrete strength at the time did not meet the design strength, are not allowed to remove and change the temporary support hoist, but can not reconcile commissioning trial. 4, according to gate lifting hoist installation centerline alignment so that the vertical and horizontal center line of the center deviation of no more than plus or minus 3mm, elevation deviation does not exceed plus or minus 5mm. Then pouring concrete or connected with two embedded steel. 5, from the closed installation machine electrical equipment, compliance with drawings and specifications, and all the electrical equipment are reliable ground. 6, each starting and closing machine installed on hoist clean, Repairing damaged protective paint, grease perfusion. (D) debugging a hoist, in the absence of load conditions to ensure that the three-phase current imbalance is not more than plus or minus 10%, and the measured current value. 2, upper and lower limit of adjustment: when the shutter is in the fully closed state, the upper limit on the compression stroke of the switch and secured to the screw. When the shutter is fully open, the compression stroke under the lower limit switch plate and fixed on the screw. 3, the main hoist controllers make adjustments to make sure the lift gate on the lower bit error does not exceed 1cm. 4. After installation, be sure to make the test run, one for no load test, which allows the screw to make two stroke, listen to any abnormal sound, detect the installation meets the technical requirements. Second, as a load test at rated load, as the two travel to observe the operation of the screw and the gate, whether the abnormal phenomenon. After confirmation before the official run. 1, the operator must have the structure, properties and methods of operation of the hoist, and have some mechanical knowledge, in order to ensure the normal operation of the machine. 2, before the operation, to conduct a comprehensive inspection from the closed machine, a part of lubrication is good, loose bolts. When the electric hoist to check the power line is switched on, the switch is good. 3, when the electric operation, the operator shall not leave the scene, they found the problem immediately shut down. 4, from the closed machine maintenance, load must be removed. 5, when used, need to inject lubricant at any time by filling hole, enough oil to keep the screw to regularly remove grease, oil coated the new guard, to prevent corrosion.
