Analysis and solution to the cause of cardoning in the flip-board car door

Cause analysis and solution for the flip-flop car door cardton

Cardton appears when the flip-flop car door opens and closes. It is divided into two situations for discussion. The editor of Kunming Haiton Car Park believes that one is that a card appears when it is installed and tested, which is a technical problem for installation. The second is how many reasons there are poor cardtons during use after delivery.

One ​​is the technical problems in the decoration stage. For example, the reason for the problem of road installation: If the road installation is not horizontal or vertical, it will cause uneven friction between the door and the road during operation, resulting in the emergence of the kton. In addition, the track is not firmly fixed and the screws are inconsistent. The track may shift slightly during door movement, affecting the smooth running of doors.

Solution: Use a horizontal meter to retest the horizontality and verticality of the track, and adjust the parts that do not meet the requirements. Make sure the track is in the same plane and perpendicular to the ground, adjusting the height or position of the track bracketSet to be realized. At the same time, check the fixing screws of the rails and use suitable tools to tighten according to the specified torque to ensure that the rails are securely installed without loosening.

Cause of roll installation: The mounting position of roll is incorrect, if it deviates from the center line of the rail, or if the mounting angle is deviated, the roll will not move in the rail, causing the door to be stuck. In addition, the model of the roller does not match the track, which will also affect the smooth operation of the door.

Solution: Carefully check the installation position and angle of the roller. If there is any deviation, reinstall the roller to ensure that the roller is located in the center of the rail and is well-secured with the rail and is flexible in the rotation. At the same time, confirm whether the roller model and the track are suitable. If it does not match, change it to the roller model of the correct one in time.

Reason for door connection: If the connection between the various boards of the flip-board car door is not tight or the connection method is incorrect, during the rise or fall of the door, relative displacement or sway may occur between the boards, causing door running jams.

Solution: Check the connecting parts between each panel of the door, such as chains, to ensure that the connection is tight and not loose. For situations where the connection method is inappropriate, adjust it according to the correct installation instructions to ensure that the connection between each panel is stable and can be operated smoothly.

Cause of installation problems between motor and motor system: The installation position of the motor is not accurate, which may lead to poor coordination between the motor chain or belt and the link and belt, and slip or jam. In addition, the tightness of the transmission parts is not suitable, and excessive looseness or tightness will affect the normal operation of the door.

Solution: Recheck the installation position of the motor to ensure that the motor is in line with the links, belts and other components of the transmission system, so that the transmission chains or belts can be transmitted normally. For the transmission of the chain, adjust the tightening wheel to make the chains tightness appropriate, and use the chains. It is appropriate for the strip to run smoothly on the chain wheel and the up and down movement range is within the specified range; for the belt movement, the tension of the belt is adjusted by adjusting the motor position or the belt tension, and pressing the belt with your fingers, and the sinking amount is within the appropriate range.

Cardon is not smooth during use after delivery

Cause of the problem of the track: During daily use, dust and mists may be accumulated in the track, such as stones, leaves, etc., which will hinder the normal sliding of the door. At the same time, long-term use may cause the track to wear, unevenness or scratches on the surface, increasing the friction between the door and the track. In addition, extreme weather conditions, such as large temperature changes, may cause the track to heat, cool down, and cause the track to deform.

Solution: Use brushes, vacuum cleaners and other tools to thoroughly clean the fog in the duct to ensure the inside of the duct. For the duct wear, you can use sand paper or grinding tools to gently polish the surface of the duct to remove uneven parts, and then apply a suitable amount of slippers , such as specialized duct sliders or silicone oil to reduce friction. If the duct is deformed due to heat cooling, it can be adjusted according to the deformation. A slight deformation can be tried to use a duct correction tool for repair; if the duct deformation is severe, a new duct needs to be replaced.

Cause of rolling wheel problem: After long-term use, the surface of rolling wheel will become unsmooth due to wear, and may even break or deform, affecting the rolling performance of rolling wheel. The bearing of rolling wheel may also be damaged due to lack of slippage or long-term rotation, resulting in rolling wheel not rotating.

Solution: Check the wear condition of the roller surface. If the wear is lighter, apply a suitable amount of grease on the roller surface and bearing area to improve its rotation performance. If the roller is broken, deformed or bearing damaged, a new roller needs to be replaced in time. When changing rollers, choose products that match the warehouse model and ensure that the safety is correct.

Door problem: The door may be deformed due to external impact, such as a car accidentally bumping into a car door. In addition, after long-term use, the balance of the door may be affected, causing the door to become stuck during operation.

Solution: For doors that are deformed due to impact, if the deformation is lighter, you can try to use professional correction tools for repair; if the deformation is severe, you need to change the damaged door panel. Switch to balance the door For problems, the balance of the door can be restored by adjusting the balance spring on the door. Generally speaking, professionals need to make precise adjustments based on the actual situation of the door to ensure smooth door operation.

Make up of motor and transmission system: The components inside the motor may be worn due to long-term use, resulting in insufficient motor power and the door cannot be brought up or down smoothly. The transmission link or belt may be loose, stretched or worn, affecting the transmission effect. In addition, the control system of the motor may be malfunctioned, such as aging control board components and poor contact, which may cause the motor to operate unstable.

Solution: For the problem of insufficient motor power, it is necessary to perform a repair of the motor, check the wear of the rotor, stator, brush and other components inside the motor, and if necessary, replace the worn parts. If there is a problem with the transmission chain or leather belt, for loose chain or leather belt, you can adjust the tension To adjust the strength of the wheel; if the chain or belt is worn seriously, a new chain or belt needs to be replaced. For the failure of the motor control system, professional technical personnel need to use professional tools to detect the control board and find fault points, such as changing aging components, repairing poor contact lines, etc.

Other objects or obstacles Cause: If the items in the cart are not placed properly, they may interfere with the door during the door operation, causing jamming. In addition, if there are bumps or depressions on the ground around the door, it may also affect the normal operation of the door.

Solution: Clean up the barriers in the garage to ensure that there are no barriers around the door running road. Check the ground around the door, polish and smooth the raised parts, and fill and repair the depressions with suitable materials to ensure that the door is not affected by the ground during its operation.
