U-shaped cable material cable manufacturer

Description :

　　The positioning of U-shaped steel cables as U-shaped steel supports requires high stress, safety and stability, and durability. The use of this equipment to process and manufacture cables can meet the requirements, and has the advantages of material saving, stable forming, high processing efficiency, and low investment benefits.

　　As a reliable connecting fastener provided by U-shaped steel brackets, U-shaped cables generally have a lap length of no more than 200mm, simple manufacturing process, and easy installation and operation. The U-shaped steel bracket connection is safe and reliable, which can improve the service life of the roadway, reduce the maintenance rate of the roadway, reduce the occurrence of safety accidents, and ensure the safety production of coal mines.

　　Characteristics of U-shaped cable

　　U-shaped cable has the ability to shrink and provide stable and reliable load-bearing capacity, adapting to the load and deformation of soft surrounding rock. It has a high utilization rate of cross section, easy support and retrieval of brackets, low maintenance volume, high recycling rate of brackets, and reduces the use of pit logs.

　　Technical requirements for U-shaped cable

　　1) The components of the cable clamp must have good interchangeability, and the bolts should be able to be directly installed on the cable clamp plate.

　　2) The surface of the cable shall not have defects such as cracks, burrs, or burrs.

　　3) The cable tray adopts quenching and tempering treatment, and the material is Q345 low carbon steel with mechanical properties not lower than that of U-shaped bracket steel;

　　4) The allowable thickness error of the formed cable tray is ± 0.5mm, and the allowable width error is ± 0.2mm. The allowable deviation of bolt hole spacing is ± 1mm.

　　5) The cable bolt should be made of round steel corresponding to the U-shaped steel material.

　　6) The bolt specification is M24, the length is 35mm, the basic thread size should comply with the provisions of GB/T96, the tolerance should comply with the provisions of GB/T197, and the accuracy is 8g.

　　7) The specification of the cable hole is M24 through-hole, and the basic thread size should comply with the provisions of GB/T96, with tolerances in accordance with GB/T197, and an accuracy of 8g.

　　8) The average working resistance of the 25U steel retractable support cable shall not be less than 100kN, the average working resistance of the 29U steel retractable support cable shall not be less than 140kN, and the average working resistance of the 36U steel retractable support cable shall not be less than 190kN.

　　9) The difference between high and low working resistance shall not exceed 25kN.

　　10) The strength of the cable and U-shaped bracket matches. zmjt055
