Description

Technical Field

[0001] This invention relates to the field of high-end wire transportation protection technology, specifically a method for protecting high-end wires during automobile transportation. Background Technology

[0002] In the high-end wire manufacturing and distribution sector, automobile transportation serves as a crucial link between production and customers. The protection of products during transportation directly impacts the final quality and market competitiveness of the wires. High-end wires, due to their high precision and surface quality requirements, are extremely sensitive to external disturbances such as vibration, friction, and collisions during transport. Even the slightest scratch can lead to a decline in product performance or direct scrapping, causing economic losses to companies and affecting customer trust. Traditional high-end wire transportation methods rely on rudimentary and unsystematic protective measures. The original designs lacked specific protective structures tailored to the shape and transport environment of the wire coils, and the interior of the truck bed lacked adequate insulation, leaving the high-end wire coils unprotected during transport. Specifically, the coils directly contact the bottom and side metal surfaces of the truck bed. Bumps, turns, and the inertia of starting and stopping during vehicle movement cause continuous friction and minor collisions between the coils and the bed. Furthermore, when multiple coils are stacked or arranged for transport, the lack of effective spacers allows adjacent coils to squeeze and rub against each other during transport, further increasing the risk of surface damage.

[0003] Furthermore, traditional protective methods lack standardized material selection, often using ordinary cardboard or untreated wood for simple padding. These materials are either insufficiently strong and easily damaged, or have rough surfaces with burrs, failing to provide effective protection and potentially becoming new sources of cable scratches. Moreover, the protection is often limited to single areas such as the bottom of the enclosure, neglecting critical areas prone to damage, such as the ends of coils and lateral contact between rows, creating blind spots. The installation process also lacks standardized operating procedures, with uneven material laying and insecure fixing being common problems. During long-distance transport or in complex road conditions, the protective structure is prone to failure, failing to continuously guarantee the safety of the cables. These issues directly lead to frequent scratches on high-end cables during transportation, increasing product defect rates and rework costs, and causing customer complaints and negatively impacting the company's brand image and market competitiveness. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a method for protecting high-end wires during automobile transportation. This method offers advantages such as comprehensive isolation and elimination of multi-dimensional scratches, and solves the problem that traditional high-end wire transportation methods suffer from rudimentary protective measures and a lack of systematic design.

[0005] (II) Technical Solution To achieve the aforementioned goal of comprehensively isolating and eliminating multi-dimensional scratches, this invention provides the following technical solution: a high-end wire transportation protection method, comprising S1 pre-transportation protective material preparation and pretreatment, S2 bottom and side protection installation of the vehicle body, S3 coil loading and interval protection setting, S4 post-loading protection reinforcement and inspection, and S5 transportation process monitoring and unloading protection, wherein S1 pre-transportation protective material preparation and pretreatment includes S101 protective material selection and specification determination and S102 protective material pretreatment; Among them, the S2 vehicle body bottom and side protection installation includes S201 bottom protection laying and S202 side longitudinal wooden board installation; Among them, the S3 coil loading and spacing protection setting includes S301 coil positioning and loading and S302 longitudinal and transverse protection installation between coils; Among them, S4 post-loading protection reinforcement and inspection includes S401 overall protection reinforcement and S402 protection effect inspection; Among them, S5 transportation process monitoring and unloading protection includes S501 real-time monitoring of the transportation process and S502 protection during unloading.

[0006] Preferably, the selection and specifications of the S101 protective material are determined as follows: The bottom protection uses high-strength corrugated cardboard with a thickness of 5-8mm (compressive strength ≥300kPa), with a single sheet size of 4m×3m. It is cut according to the actual size of the bottom of the car body to ensure that the edge of the cardboard extends 5-10cm beyond the bottom edge of the car body. The longitudinal protective boards are made of solid wood with a moisture content of ≤12%. The longitudinal boards 2 used on both sides of the box are 3m×0.15m×0.05m (length×width×thickness), and the longitudinal boards 3 used between the ends of the coils are 1.6m×0.15m×0.05m. The horizontal protective wooden board 4 is made of solid wood of the same material, with a size of 2.6m×0.15m×0.05m. The surface is sanded (surface roughness Ra≤6.3μm) to prevent the burrs of the wooden board from scratching the wire.

[0007] Preferably, the S102 protective material pretreatment: All protective wooden boards are treated with anti-corrosion coating, sprayed with environmentally friendly anti-corrosion paint (dry film thickness ≥30μm), and allowed to air dry for ≥24 hours; A moisture-proof agent is evenly coated on the bottom cardboard surface to form a moisture-proof layer (0.1-0.2mm thick), enhancing its moisture-proof performance during transportation.

[0008] Preferably, the bottom protective layer of S201 is laid as follows: Clean debris and protrusions from the bottom of the car body to ensure that the flatness error of the bottom of the car body is ≤5mm; Lay the pre-treated bottom cardboard 1 flat on the bottom of the box, with an overlap width of 10-15cm between the cardboard pieces. Secure the overlap with environmentally friendly tape (tape width ≥ 5cm) to ensure that the cardboard is wrinkle-free, has no gaps, and fits tightly against the bottom of the box.

[0009] Preferably, the longitudinal wooden board on the side of S202 is installed: At the bottom of the inner walls on both sides of the vehicle body, longitudinal wooden boards 2 are installed along the length of the body. The wooden boards are fixed to the body with detachable buckles (the buckle spacing is ≤50cm). Adjust the verticality of the longitudinal wooden board 2 to ensure that the gap between the wooden board and the side of the box is ≤2mm, and the top is 10-15cm higher than the stacking height of the coils.

[0010] Preferably, the S301 reel positioning and loading: Using hoisting equipment, the high-end wire coils are slowly placed on the bottom protective cardboard according to the preset arrangement (horizontal spacing of a single row ≥ 30cm), with the central axis of the coils parallel to the length direction of the car body; During the loading process, maintain the verticality error of the coil axis ≤3° to avoid coil tilting leading to protection failure.

[0011] Preferably, the S302 reel inter-coil longitudinal and transverse protective installation is as follows: Between the ends of two adjacent rows of coils, a longitudinal wooden board 3 is inserted along the coil axis. The two ends of the wooden board contact the longitudinal wooden boards 2 on both sides of the box, ensuring that the wooden board is tightly fitted to the end of the coil (gap ≤ 3mm). One longitudinal wooden board 3 is set every other coil. Between the two horizontal coils between rows, a horizontal wooden board 4 is placed along the width of the box. The two ends of the wooden board are pressed against the outer circular surface of the coils on both sides. At least two horizontal wooden boards 4 are set between each row of coils, and the spacing is evenly distributed (spacing deviation ≤ 10cm).

[0012] Preferably, the S401 provides overall protective reinforcement: Cover the top of the coil with high-strength corrugated cardboard of the same specifications as the bottom, align the edges of the cardboard with the bottom cardboard, and use elastic bandages (width ≥ 8cm) to fix the top cardboard and the bottom protection in place. The tension of the bandages should be controlled at 50-80N to prevent the coil from shaking up and down during transportation. For the contact points between the coil and the longitudinal wooden board 2 and the transverse wooden board 4, add rubber buffer pads with a thickness of 2-3mm (Shore hardness 60-70HA) to reduce friction damage caused by transportation vibration.

[0013] Preferably, the S402 protection effect check is as follows: Check that all protective wooden boards are securely fixed. Shake the boards by hand; the displacement should be ≤1mm. Check the gap between the coil and the protective material to ensure that there is no direct contact between the coil and the housing, or between coils, and control the gap to 5-10mm. Simulate transportation vibration test (amplitude ±5mm, frequency 2-5Hz), test time ≥5 minutes, and check after the test that the protective structure is not loose and the coil is not displaced.

[0014] Preferably, the S501 transportation process is monitored in real time: Vibration sensors are installed in the vehicle's cab to monitor vibration acceleration (threshold ≤ 10 m / s²) in real time during transportation. 2 When the vibration exceeds the threshold, a warning is issued to remind the driver to slow down; Every 2 hours, the condition of the coil and protective structure is checked using the vehicle-mounted camera, and any abnormalities are recorded. S502 protection during unloading: Before unloading, remove the top elastic bandage and covering cardboard, and check the condition of the coil and spacer protective boards. During unloading, keep the hoisting equipment running smoothly and control the hoisting speed at 0.3-0.5 m / s to avoid collision between the coil and the protective wooden planks; After unloading, reusable protective boards and cardboard are recycled and stored separately for future use.
