JB/T8137.1~8137.41999
The types and dimensions of this standard JB/T8137.1~8137.4-1999 are revised with reference to DIN46391. This standard JB/T8137 includes the following parts under the general title "Wire and Cable Delivery Tray": JB/T8137.1 Part 1: General provisions Appendix A Reference table of tray length; JB/T8137.2 Part 2: All-wood structure delivery tray, JB/T8137.3 Part 3: All-steel tile structure delivery tray; JB/T8137.4 Part 4: Steel composite structure delivery tray; Parts 2 to 4 should be used together with Part 1. In 1995, the standard number of GB4005-83 was changed to JB/T8137-95, but its content was not revised. When it is revised according to DIN46391 standard, d. is defined as the diameter of the shaft hole, which is consistent with DIN standard and small-diameter machine wire drum standard; and the original standard only divides the size and technical requirements into the method of writing partial standards, and divides the delivery drum into full wood structure, full steel corrugated structure and steel composite structure according to the structure, and the original iron and wood structure is classified into steel composite combination. Each part describes in detail the model, specification, material, basic technical requirements and test items of various delivery drums. From the date of implementation, this standard will replace JB/T8137.1~8137.2--95 at the same time. Appendix A of Part 1 of this standard is a reminder appendix. This standard is proposed and managed by the National Technical Committee for Standardization of Wires and Cables. This standard is drafted by Shanghai Cable Research Institute. The main drafters of this standard are: Wang Shanqing, Miao Dejiang, and Sun Xin. 96

4 Specifications
The specifications of the cable drum shall comply with the provisions of Table 1. The cable drum length of the delivery drum can be found in Appendix A. 98
JB/T8137.1—1999
The cable head protective cover and storage box shall not exceed this size. 1. It is the maximum allowable size. All bolts, nuts, and 2V exposed from the side panels are the volume of the wire drum,
lr(at-dl)
5 Outer guard plate of the delivery tray
5.1 The outer guard plate should be made of wood strips or thin steel plates. JB/T8137.1-1999
According to the different protection requirements for wire and cable products, other materials are allowed to be used. 5.2 The metal structure delivery tray should reserve the hole position of the outer guard plate. 6 Inspection and acceptance
6.1 Acceptance rules
6.1.1 The product shall be inspected and qualified by the technical inspection department of the manufacturer before it can be shipped out of the factory, and the shipped products shall be accompanied by a product inspection certificate. 6.1.2 The product shall be accepted according to the specified inspection method, and the inspection types are type inspection (T) and routine inspection (R). 6.1.3 The delivery tray after recycling and repair shall also be inspected in accordance with the requirements of this standard. 6.2 Inspection method
6.2.1 Inspection method for dimensional tolerance of delivery trays6.2.1.1 Inspection method for side plate diameter d1 and outer width !2 Use steel tape (leather) ruler to measure.
6.2.1.2 Inspection method for cylinder diameter dz and inner width 12 When the cylinder diameter is less than or equal to 300mm, use calipers to measure the cylinder diameter of the wire drum, and measure its value with a steel tape. When the cylinder diameter is greater than 300mm, the radius difference △R between the side plate and the cylinder can be measured, and d2 can be calculated by the formula: dz=d-2△R. The inner width i2 is measured with a steel tape (leather) ruler.
6.2.1.3 Inspection method for shaft hole diameter d2 Use a vernier caliper to measure the cylindrical hole diameter.
6.2.2 Inspection method for shape and position tolerance of delivery trays The inspection method for shape and position tolerance of delivery trays is shown in Figure 2 and Table 2. Figure 2 Test method for shape and position tolerance
