3 Technical requirements
Product nameplate
3.1 The manufacture of the drilling platform shall comply with the requirements of this standard and be manufactured according to drawings and technical documents approved through the prescribed procedures. 3.2 Various steel materials used for the drilling platform shall comply with the corresponding national standards and industry standards. The mechanical properties of the materials used in the design shall take the minimum values ​​of the material specifications recommended by the national standards or industry standards. 1 The main bearing parts shall not use steel with a minimum yield limit less than 231MPa and steel pipe with a minimum yield limit less than 245MPa.
The ratio of shear yield limit to tensile yield limit is 0.58. Various steel materials used for drilling platforms should have quality certificates from the original manufacturers, otherwise they should be subjected to chemical composition analysis and mechanical property tests before they can be used.
3.3 Materials specified in the drawings may be substituted, but it should be ensured that the product performance will not be reduced after substitution. 3.4 Fasteners and connectors used in drilling platforms shall comply with the requirements of the drawings. 3,5 Steel and steel plates and cutting surfaces shall meet the requirements of the drawings. Electric welding rods shall comply with the provisions of GB5117 and GB5118. 3.6
3.7 Welding heads shall comply with the provisions of GB985 and GB986. The welding of drilling platforms shall comply with the provisions of SY5305. 3.8
3.9 The deformation of components after assembly welding is allowed to be corrected. After correction, the flatness tolerance of the plane on the turntable beam is 6mm. 3.10 Unqualified holes can be repaired with electric welding rods once, and the surface can be re-drilled after grinding. 3.11 All fasteners and connectors should be able to be installed smoothly, and it is not allowed to be assembled by strong methods such as chain beating and jack. 3.12 All threaded fastener connections are not allowed to be loose, and anti-loosening devices must not be missing. 3.13 The movable railing should be able to be smoothly installed in the railing socket. 3.14 The painting should comply with the provisions of SY5308. Approved by the Ministry of Energy of the People's Republic of China on February 22, 1993, and approved on August 1, 1993.
4 Test methods and inspection rules
4.1 Factory inspection
SY 5471--92
Each drilling rig should be inspected before leaving the factory, and can only leave the factory after passing the inspection. Check the flatness of the plane on the turntable beam, which shall comply with the provisions of Article 3.9. 4.1.1
4.1.2 Check the installation of all fasteners and connectors, which shall comply with the provisions of Article 3.11. 4. Straight, 3 Check all threaded fastener connections, which shall comply with the provisions of Article 3.12. 4.1.4 Check the installation of movable railings, which shall comply with the provisions of Article 3.13. 4.1.5 Check the appearance quality of the drilling platform, which shall comply with the provisions of Article 3.14. 4.2 Type inspection
4.2.1 Carry out type inspection on the first prototype of a new product or a major structural change. 1.2.2 For products subject to type inspection, load the turntable beam and the root box to the maximum test load value respectively. Loading shall be carried out in stages, and each load level shall be repeated at least once. The maximum test load value is equal to the maximum load of the drilling platform. The loading time of the maximum test load shall not be less than 15 minutes, and the loading time of the other levels of test loads shall not be less than 3 minutes. 4.2.3 For the parts with high stress on the test product, strain gauge shall be used to test the stress values ​​under various test loads. All measured stress values ​​shall be less than the design allowable value.
5 Marking, packaging and transportation
5.1 Marking
The product nameplate of the drilling platform shall be fixed at the position specified in the drawing. The nameplate shall comply with the provisions of JB8. The content of the nameplate is as follows: a. Product name and model
b. Maximum load
