　　Winding open and close machine installation process: after opening and closing equipment arrived at the construction site should be a comprehensive inspection, in accordance with relevant provisions of the DL/T5019-94 "water conservancy and hydropower engineering hoisting open and close machine manufacture, installation and acceptance of norms" (hereinafter referred to as "DL/T5019"), after passing the examination, square can be installed. Two check foundation bolts buried position, buried depth and exposed part of the bolt length should be accurate. Three check lift hoist platform height, the deviation should be no more than 5mm, the level of deviation should be less than 0.5/1000. Four lift hoist should be installed according to the lifting center alignment, the longitudinal, transverse center line deviation should not exceed 3.0mm. Five the length of the wire rope wound on the reel, when the hanging point in the lower position, the number of laps left on the drum is not less than 4 laps, when the hanging point in the upper position, the wire rope is not wound to the drum part of the light tube. Six double hanging point opening and closing machine Diaoju error not exceeding + 3.0mm; taut wire rope, and two lifting shaft center line should be at the same level, the difference in the orifice shall not exceed 5.0mm. Seven winding hoist machine electrical equipment installation shall comply with the SD315-93 the fixed hoist type open and close machine general technical conditions "of the relevant provisions. Eight electrical equipment through the test should be carefully checked all wiring and should be consistent with the design, the entire line of insulation resistance must be greater than 0.5M. In the experiment, the temperature rise of the motor and electrical components should not exceed their respective allowable values, the test should be used in the machine's own electrical equipment. If the contact and other components of the test have a burning, the reason and the replacement shall be identified. Nine open and close the no-load test of the whole trip should be up and down 3 times. Check and adjust the following electrical and mechanical parts.

　　Winding open and close machine installation notes: 1, the installation base foundation should be smooth and firm, left foot screw position, winch hoist in place after the leveling casting and moulding. 2, the first wire rope around the balance wheel, the length of the rope on both sides of the average, through the moving pulley group to the wire rope around, while at the same time fixed at the end of the drum. Winding open and close machine, installation and maintenance; opening and closing machine debugging, under no load, to ensure balanced three-phase current does not exceed plus or minus 10%, and measured current value. 2, the upper and lower limit of the adjustment: when the gate is in the state of the whole, the upper bound of the travel switch and fixed on the screw. When the gate is fully open, the lower limit position is pressed down and the stroke switch is fixed on the screw. 3, winch hoist the main controller adjustment, must ensure that the lift of the gate to the lower limit, the error is less than 1cm. 4, after installation, trial run, one for no load test that screw two travel, listen to their abnormal sound, installation and testing is in accordance with the technical requirements. Two for the load test, under the rated load, for the two stroke, observe the operation of the screw and the gate, there is no abnormal phenomenon. No mistake in the rear can be officially run. 1, the operator must grasp the structure, performance and operation of the hoist, and a certain mechanical knowledge, to ensure the normal operation of the machine. 2, before the operation, the closure of the machine for a comprehensive examination, a part of the lubrication is good, there is no loose bolts. Electric hoist check the power line is connected, the switch is good. 3, electric operation, the operator shall not leave the scene, found the problem immediately stop. 4, from the maintenance of the machine, the load must be cleared. 5, when in use, need to keep from oil hole injection lubricating oil, to keep enough oil, screw should be regularly cleaned grease, painted lip oil, to rust.
