Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a paving machine cable. Background Art
[0002] A paver is a special machine used to lay asphalt mixture and other graded materials. It evenly spreads the mixed asphalt mixture (asphalt concrete or black aggregate) on the prepared roadbed or base according to certain technical requirements (thickness and cross-sectional shape), and gives it preliminary compaction and leveling. The working environment of the paver cable is between 100-140℃, and it is often moved frequently. The existing paver cables are mainly imported and need to be replaced frequently, which are prone to aging, brittle cracking, conductor breakage and other problems. Utility Model Content
[0003] In view of this, the utility model proposes a paver cable to solve the problem that the existing paver cable is prone to aging and brittle cracking, and conductor breakage.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A paving machine cable, comprising a cable with multiple cable cores twisted together, an inner sheath, a shielding layer, an outer sheath and a heat insulation layer, wherein the cable core comprises a conductor and an insulation layer, and the insulation layer is extruded from high temperature resistant and extremely soft platinum silicone rubber. The inner sheath is extruded on the outside of the cable, the shielding layer is woven on the outside of the inner sheath, the outer sheath is extruded on the outside of the shielding layer, and the heat insulation layer comprises a quartz wire braided layer and a fluorosilicone resin paint coating. The quartz wire has high temperature resistance and heat insulation capabilities, and the fluorosilicone resin paint has the ability to insulate and reflect heat, and the combination of the two improves the heat insulation capability of the cable.
[0006] Preferably, the conductor is formed by twisting a number of tinned copper wires, and the twisting pitch is 8-10 times.
[0007] Preferably, the inner sheath is extruded from platinum silicone rubber with an extrusion thickness of 0.5 mm. Platinum silicone rubber has a high temperature resistance grade and good aging resistance.
[0008] Preferably, the shielding layer is braided with tinned copper wires, which can improve the shielding and tensile strength of the cable, and the braiding density is not less than 80%.
[0009] Preferably, the outer sheath is extruded from platinum silicone rubber with an extrusion thickness of 0.5 mm.
[0010] Preferably, the braiding density of the quartz wire braided layer is not less than 70%.
[0011] Compared with the existing technology, the beneficial effects of the utility model are:
[0012] The utility model paver cable adopts platinum silicone rubber, which has stronger aging resistance than ordinary silicone rubber and is not easily decomposed at high temperature, ensuring long-term effective use. The conductor twisting pitch and the cable twisting pitch are dense, ensuring that the entire cable is soft enough and suitable for frequent bending. The combination of non-metallic braiding and fluorosilicone resin paint coating effectively isolates heat and ensures that the cable can be used for a long time. BRIEF DESCRIPTION OF THE DRAWINGS
