During the revision, editorial changes will be made to the original standard, but the main technical content will not change. This standard replaces ZBJ81008.19 from the date of implementation. This standard is produced and imported by Beijing Hoisting and Conveying Machinery Research Institute. This standard was drafted by: Beijing Hoisting and Conveying Machinery Research Institute. Scope Machinery Industry Standard of the People's Republic of China Overbead conveyorDrag rlveil essehalinThis standard specifies the types, basic parameters, dimensions and technical requirements of detachable chain for overhanging conveyors. This standard is applicable to ground conveyors. 2 Reference standards JH/T 9016.1-1999 The new provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised. The service provider who uses this standard should consider the possibility of using the latest version of the following standards. GB.T9785-1988 Chain and sprocket technology 3 Types, basic parameters and dimensions 3.1 The detachable armor of the conveyor chain adopts two structural types: die forging chain (Figure 1) and stamping chain (Figure 2), and two types of structure. 3.2 The basic parameters and dimensions of the detachable load should comply with the requirements of Figure 2 and Table 2. It is recommended to use the standard of "10". The National Machinery Industry Bureau approved the shaft on June 28, 1999. 2000H) [-01 implementation. Most names. Name. Pitch. Meshing pitch.

The length of the chain link should be consistent with the direction of the steel fiber. 4.2 The surface of the chain parts shall not have cracks, marks, oxide scale and traces of material overheating. The chain parts shall not be repaired. 4.3 The assembled chain shall ensure that all joints can rotate flexibly. 4.4 The length of the chain assembly shall be determined by the manufacturer and the user. 5 Test methods and inspection rules 5.1 All chains shall be tested for the flexibility of the external and joint parts according to the requirements of 4.3 and 4.4. 5.2 From each batch of chains produced, select 3 chains with 5 sections and 1 chain with the specified length (then 5.5] to carry out the test. The 5-section chain segment H is required to check whether it meets the requirements of 3.2 (except the specified length of the chain); the specified length chain segment is used to check the average length tolerance L specified in the corresponding table. When the measurement result does not meet the requirements, a repeated test is carried out and the number of repeated test samples is doubled. The result of the repeated test is the final result. 5.3 The total length of the annual batch chain should not exceed 1000m. 5.4 The row spacing P is 0.01. 5.5 Take the chain segment with the specified length of 32mm or 500mm and measure it under the condition of full-length support and 0 .0" Measure its length under the state of ultimate control load. 5.6 All chain pieces are inspected periodically. 5.7 Use a material tensile testing machine to determine the ultimate tensile load of the chain. The test length is at least 4 pitches, and both ends are connected to the testing machine with pins. The chain must be able to rotate freely. If the breakage occurs near the clamp, the test can be repeated. 5.8 Determine the weight of each meter of the chain. Take one or several sections with a length of about 15m for testing. 59 When the structure, material or process of the chain is changed, the first batch of chains produced after the change should be type tested. The test content should include: a) Measure the ultimate total difference of the standard length of the chain, and the sample number is 10 pieces randomly selected. b) Measure the light ultimate tensile load of the chain, and the sample number is randomly selected. Pieces. Stone marking, packaging and storage 6.! Each chain section should be marked with the chain model, standard number and manufacturing mark on at least one inner or outer ring. The chain should be packed in a closed box. Before packing, apply anti-rust grease: Use plastic film to wrap the chain. When the chain is shipped, the packaging box shall include the following contents: a) Product name and model: b) Factory number (or contract number: c) Box size and destination (port), manufacturer name and shipment date. 4 Products should be stored in a well-ventilated warehouse without corrosive gas without opening the package. 7.1 Under the conditions of following the storage, installation and use rules, the manufacturer shall ensure that the chain meets the requirements of the standard. 7.1 The warranty period of a group of chains is 18 months, but not more than 24 months from the date of shipment. During the warranty period, if the chain is damaged due to poor quality and cannot be used normally, the manufacturer shall repair or replace it for the user free of charge.
