The components of the machine should be in good order and in good order, and should not cause danger and damage to the components of the unit. 1. The depth of the site should be considered when installing the machine. 4.3 The construction personnel should follow the provisions of this specification or other related technical documents, and should comply with the relevant safety requirements and labor protection regulations. 4.4 According to the characteristics of the machine, the installation team should be composed of specially trained or professional installation personnel, and the site control should be designated. 5 Technical preparation 5.1 Before installation, read the instruction manual carefully, understand and be familiar with the structural characteristics of the installed unit, and the installation steps and methods of the unit. 5.2 The packing list of the service product should be carefully checked and checked to see if the components and parts of the unit are complete. If missing parts are found, they should be replaced. If damaged, they should be repaired and replaced. 5.3 Prepare and use materials, install, and hoist the equipment according to the instructions on the page. 54. The installation team shall formulate necessary construction plans, operating procedures and safety measures according to the specific construction case. 6 Installation procedures 6.1 Foundation G.1.1 Foundation pit The foundation pit control includes: B/T10395—2004 a) Select a suitable location at the determined installation site to dig a spot and determine the water half standard of the foundation; 3) Dig the foundation pit according to the requirements of the instruction manual; c) When the tower foundation pit is over-explored or the soil is loose, Lou Use concrete workers to pour and level. 6.1.2 Pouring foundation The details of the dense foundation should include: a) The inner surface of the concrete mold should be neat and connected, and the design and construction quality of the foundation should be guaranteed. When pouring concrete without a template, it is necessary to prevent mud and other impurities from leaking into the concrete. :) The anchor bolts and embedded parts in the foundation should be cleaned of rust in advance, and the threaded part should be separated. The anchor bolts should be firmly fixed and their position should be accurate ) The inserted foundation tower is completed together with the tower frame The lowest section is structurally assembled, temporarily fixed, aligned, and then placed in place. The flow system is checked and corrected at any time: d) The cement grade shall not be lower than the requirements of the installation manual, and the platform ratio shall meet the requirements of the installation manual. In winter, the foundation surface should be protected by the following materials: 6.1.3 Foundation maintenance Foundation maintenance should take into account: a) Start watering maintenance 2 hours after pouring (3 hours in hot and windy weather): Cover the surface of the foundation with curing materials. b: The concrete foundation made of ordinary silicate and mineral silicate water filtration shall not have a watering maintenance period of more than 12 months. In hot and dry areas, the watering maintenance period shall be extended. This type of cement should not be used for winter construction. 6.2 Installation of pull-type tower tube units 6.2.1 At the installation point, choose the starting direction and fix the seat and box according to the regulations. 6.2 Pre-install the tower control cable, adjust the spiral buckle, and position the tower pipe upright on the pool surface. 6.2.3 Install all components such as the rotating body, generator, wind wheel, and feeder snake, and connect the output power. 6.2.4 After the machine is in a repairable state, use personnel or lifting equipment to complete the machine and adjust it. 6.3 Installation of light-lift tower unitsbZxz.net 6.31 Assembling the tower The tower installation should include: ) Assemble the tower according to the tower installation method and precautions provided in the service manual: , when the hole is enlarged due to misalignment, the increased true diameter of the enlarged hole should exceed mm. If it exceeds 3mm, it should be re-processed after welding. It is strictly forbidden to use the gas pair method to expand: c; After the tower is installed, all the connections of the tower parts should be staggered on the opposite sides of the tower, and tightened gradually in one or three times to the torque required by the manual. The bolt stress detection method should be effective: 1) After the tower is assembled, use instruments to check whether the tower is vertical. The inclination of the tower should not exceed 3. 5.3.2 Assembling the upper part of the tower The assembly of the upper part of the tower is divided into: 1) Split assembly method: According to the structural characteristics of the unit, the components of the three parts of the unit are assembled in sequence on the tower body: b) Overall lifting method: Assemble all the power components on the tower on the ground, lift them with wind equipment, and then fasten them to the tower: 6.4 Installation of the electrical system According to the requirements of R17 and the instruction manual, set up the transmission lines and indoor controllers, core devices, battery and electrical circuits. 5.5 Safety regulations 551 The unit should be installed in a location without heavy rain and with strong winds not exceeding 5m/s. 2 5.5.2 The whole unit should be installed in a weather environment.
