[0002] In modern architecture, overhead door is widely used in various places from ordinary residence to large commercial buildings, industrial plants and even warehousing facilities due to its good sealing, intuitive opening mode and other advantages. Compared with conventional size overhead door, the span of super-wide overhead door increases significantly, causing its weight to soar, bringing great load pressure to the rotation and support system of the door body. In this case, the automatic door spring compensation device can play a key role. It not only bears the responsibility of controlling the automatic closing of the door body and accurately adjusting the closing speed, but also relieves the pressure exerted on the rotation and support system due to the weight increase of the door body to a certain extent within its load range, assisting in maintaining the stable opening and closing of the door body and ensuring the normal operation of the entire door system.
[0003] Although the existing automatic door spring compensation device can perform routine load automatic compensation operation on super-wide overhead door, the box body and cover body are connected by bolts in the actual use process, which is intended to ensure stability, but this adds many inconveniences to routine maintenance. Regular inspection, cleaning and debugging of the automatic door spring are essential, and each operation means that the box cover needs to be opened, and the staff needs to repeatedly turn multiple bolts, which is tedious, time-consuming and labor-intensive, thus the use convenience of the automatic compensation device is insufficient. Moreover, the cover body and box body are simply spliced, and the interface lacks effective sealing design. Over time, dust and impurities enter. These fine particles accumulate inside the spring, gradually blocking the precise channel of hydraulic oil flow. The valve opening and closing is blocked, the piston operation is delayed, and the smooth hydraulic transmission mechanism frequently fails. In terms of door body performance, it is sluggish when opening and suddenly stalls when closing, with a loud and irritating noise. The accuracy of the automatic compensation device is greatly reduced, which seriously affects the use experience, and thus the use effect of the automatic compensation device is not good enough.
