Bagaimanakah saya dapat mengelakkan mekanisme angkat katil dari tidak sengaja meluncur atau terjebak semasa operasi?

Preventing unexpected sliding or jamming of the Bed Lift Mechanism during operation is an important part of ensuring its safety and reliability. Berikut ini membincangkan secara terperinci bagaimana untuk mencegah masalah ini secara berkesan daripada berlaku dari pelbagai aspek seperti reka bentuk, pemilihan bahan, proses pembuatan, sistem kawalan dan penyelenggaraan:

Optimization in the design stage
Use a reliable locking mechanism
Tambah peranti mengunci mekanikal atau elektronik ke mekanisme angkat katil untuk memastikan ia dapat dikunci secara automatik selepas ketinggian sasaran dicapai.
Common locking methods include:
Mechanical friction lock: fix the position by increasing friction.
Hydraulic self-locking: use the pressure balance principle of the hydraulic system to achieve stable support.
Electromagnetic lock: control the electromagnet to attract through current to prevent accidental movement.
Enhance structural rigidity
Gunakan bahan kekuatan tinggi (seperti keluli aloi atau aloi aluminium kelas penerbangan) untuk mengeluarkan komponen utama untuk mengurangkan risiko jamming atau gelongsor yang disebabkan oleh ubah bentuk.
Ensure the quality and tightness of connectors (such as bolts, pins, etc.) to avoid loosening or falling off.
Design multiple protection systems
Configure overload protection device: When the load exceeds the rated value, the system will automatically stop running to prevent damage.
Set limit switch: limit the lifting range to avoid jamming or failure caused by exceeding the design limit.
Improvement of control system
Accurate speed control
Use advanced motor drive technology (such as brushless DC motor) to ensure smooth and controllable lifting process.
Integrate PID control algorithm to adjust the motor output power in real time to avoid shock caused by sudden acceleration or deceleration.
Intelligent monitoring and feedback

Install sensors (such as displacement sensors, pressure sensors) to monitor the status of bed lift in real time.
If an abnormality is detected (such as uneven load or obstructed movement), the system can immediately suspend operation and issue an alarm.
Emergency brake function
Integrate emergency brake button in the control system, users can quickly stop the equipment operation when abnormalities are found.
Untuk mengangkat katil elektrik, fungsi perlindungan kuasa juga boleh direka untuk memastikan kedudukan semasa dapat dikekalkan apabila kuasa terganggu.
Selection of materials and manufacturing processes
Select high-quality materials
Komponen utama (seperti landasan panduan, skru plumbum, galas, dan lain-lain) hendaklah dibuat daripada bahan tahan haus dan tahan kakisan untuk memanjangkan hayat perkhidmatan.
Lubricated parts should use high-performance lubricants to reduce friction and wear.
Precision machining and assembly
Improve the machining accuracy of parts and ensure that the clearance between components meets the design requirements.
Strictly follow the operating specifications during the assembly process to avoid jamming or sliding problems caused by improper installation.
Daily maintenance and care
Pemeriksaan biasa
Secara kerap periksa status semua bahagian yang bergerak, termasuk landasan panduan, slider, skru plumbum, dan lain -lain, untuk memastikan permukaannya licin dan tidak rosak.
Check whether the locking device is working properly and adjust or replace it if necessary.
Lubrication and cleaning
Regularly lubricate moving parts to prevent jamming due to dryness.
Remove dust, dirt or other foreign matter to prevent them from affecting the normal operation of the mechanism.
Load test
Regularly perform load tests to verify whether the bed lift performs stably under different weights.
If abnormal conditions (such as vibration, noise or sliding) are found, the causes should be promptly investigated and repaired.

Langkah -langkah di atas dapat mengurangkan risiko kemerosotan kemalangan atau jamming mekanisme angkat katil semasa operasi, dengan itu meningkatkan keselamatan, kebolehpercayaan dan hayat perkhidmatannya. Kaedah ini bukan sahaja boleh digunakan untuk senario seperti katil perubatan dan katil kejururawatan, tetapi juga kepada platform perindustrian dan kawasan aplikasi lain yang serupa.
