Foreword

According to the "National Energy Administration on the issue of the.2015 energy sector industry standard system (revision) According to the requirements of the “Notice of the Plan” (Guoneng Technology (2015) No. 283), the specification compilation team has been extensively Investigate and research, seriously sum up practical experience, refer to relevant domestic advanced standards, and extensively collect On the basis of soliciting opinions, revise this specification. The main technical content of this code is. basic regulations, design principles and requirements, loads, Materials, machinery, structure, electrical, safety. The main technical content of this specification revision is. This code replaces "Code for Design of Hoist Gear for Hydropower and Water Conservancy Projects" DL/T 5167-2002 The relevant content of the screw hoist design in the article; this specification replaces the "QL type screw hoist Machine series parameters" SD 297-88 and "QL type screw hoist technical conditions" SD 298-88. -Added the classification of screw hoist. -Added the relevant regulations for the swing type screw hoist to lift the arc gate. -Added anti-corrosion regulations. -Increased the requirement of welding structure for the base and chassis. -Added the design requirements of the rolling screw hoist. -Added "Security" chapter. -Adjusted the material table of the load-bearing nut. -Adjusted the model and series parameters of the screw hoist, and expanded the hoisting force series. -The requirement that the rise angle of the thread center line is not less than 4° has been deleted.
