濟(jì)南電動(dòng)卷閘門驚險(xiǎn)掉落？配件尺寸偏差是隱形殺手

　　Jinan electric rolling gate fell dangerously? Dimensional deviation of accessories is an invisible killer

　　在濟(jì)南的商鋪、廠房日常運(yùn)營中，電動(dòng)卷閘門突然故障的情況并不少見，但若遇到關(guān)門時(shí)一端突然掉落的驚險(xiǎn)場景，不僅可能損壞門體，還存在極大隱患。近期就處理了這樣一起維修案例：電動(dòng)卷閘門關(guān)門過程中，一端突然下墜，現(xiàn)場查看后發(fā)現(xiàn)軌道下方有掉落的軸心，傳動(dòng)軸也存在尺寸偏差。今天就結(jié)合這個(gè)案例，給大家科普濟(jì)南電動(dòng)卷閘門配件品質(zhì)的重要性，以及這類故障的成因與維修要點(diǎn)。

　　In the daily operation of shops and factories in Jinan, it is not uncommon for electric rolling gates to suddenly malfunction. However, if there is a thrilling scene where one end suddenly falls off when closing the door, it may not only damage the door body, but also pose a great safety hazard. Recently, we handled a repair case where one end of an electric roller shutter suddenly fell during the closing process. Upon on-site inspection, it was discovered that there was a falling axis under the track, and there was also a dimensional deviation in the transmission shaft. Today, based on this case, we will explain to you the importance of the quality of accessories for Jinan electric rolling gate, as well as the causes and maintenance points of such faults.

　　先還原這起驚險(xiǎn)故障的排查過程：用戶反饋卷閘門關(guān)門時(shí)一端突然掉落，到場后在軌道下方發(fā)現(xiàn)了掉落的軸心，測量后發(fā)現(xiàn)該軸心比正常規(guī)格短了約五公分；隨后檢查上方卷筒位置，又發(fā)現(xiàn)傳動(dòng)軸同樣存在尺寸偏差，標(biāo)準(zhǔn)長度應(yīng)為6.76米，而實(shí)際安裝的傳動(dòng)軸僅6.7米，短了關(guān)鍵的六公分。綜合判斷，正是這兩處配件的尺寸偏差，導(dǎo)致門體運(yùn)行時(shí)受力失衡，終引發(fā)掉落故障，同時(shí)還伴隨電機(jī)支架板變形的連鎖問題。這類因配件尺寸不達(dá)標(biāo)導(dǎo)致的故障，隱蔽性強(qiáng)，初期使用可能無異常，一旦發(fā)作就容易造成嚴(yán)重?fù)p壞。

　　First, let's restore the troubleshooting process of this dangerous malfunction: the user reported that one end of the roller shutter suddenly fell off when it was closed. Upon arrival, the axis of the falling object was first discovered under the track. After measurement, it was found that the axis was about five centimeters shorter than the normal specification; Subsequently, the position of the upper drum was checked and it was found that there was also a dimensional deviation in the transmission shaft. The standard length should be 6.76 meters, but the actual installed transmission shaft was only 6.7 meters, which was six centimeters shorter than the critical length. Overall, it is the size deviation of these two components that caused the door to experience unbalanced force during operation, ultimately leading to a falling fault, and also accompanied by a chain problem of deformation of the motor bracket plate. This type of malfunction caused by the size of accessories not meeting the standard has strong concealment and may not have any abnormalities during initial use. Once it occurs, it is easy to cause serious damage.

　　可能有用戶疑惑，僅僅幾公分的尺寸偏差，為何會(huì)導(dǎo)致卷閘門掉落這樣的大故障？這就需要了解電動(dòng)卷閘門的傳動(dòng)原理：門體的升降全靠傳動(dòng)軸與軸心的精準(zhǔn)配合，通過均勻受力帶動(dòng)卷筒轉(zhuǎn)動(dòng)。傳動(dòng)軸和軸心的長度都是經(jīng)過精準(zhǔn)計(jì)算的，需與門體寬度、軌道間距完全匹配。當(dāng)兩者尺寸偏短時(shí)，傳動(dòng)結(jié)構(gòu)無法形成穩(wěn)定的受力支撐，門體運(yùn)行中會(huì)出現(xiàn)偏移、卡頓，長期受力不均會(huì)加劇部件磨損，終導(dǎo)致軸心脫落、傳動(dòng)軸變形，甚門體下墜?？此莆⑿〉某叽缯`差，實(shí)則是危及的“隱形殺手”。

　　Some users may wonder why a size deviation of only a few centimeters could cause a major malfunction such as the roller shutter falling off? This requires understanding the transmission principle of the electric roller shutter: the lifting of the gate body relies entirely on the precise coordination between the transmission shaft and the axis, which drives the drum to rotate through uniform force. The length of the transmission shaft and axis is accurately calculated and needs to be perfectly matched with the width of the door and the distance between the tracks. When the dimensions of the two are too short, the transmission structure cannot form a stable force support, and the door body will experience displacement and jamming during operation. Long term uneven force will exacerbate component wear, ultimately leading to axis detachment, transmission shaft deformation, and even door body falling. Seemingly small size errors are actually "invisible killers" that endanger safety.

　　這類故障的維修難度較大，需要團(tuán)隊(duì)和規(guī)范流程才能確保修復(fù)后穩(wěn)定。此次維修給出的方案是更換整條傳動(dòng)軸和變形的電機(jī)支架板，具體步驟繁瑣且耗費(fèi)心力：步先用電焊機(jī)將傳動(dòng)軸的孔吹大，套入一截鋼管適配尺寸；再用手拉葫蘆緩慢將門體拉起、平穩(wěn)放下，避免二次損傷；隨后拆除長度不達(dá)標(biāo)的舊傳動(dòng)軸，更換為標(biāo)準(zhǔn)6.76米的新軸；更換變形的支架板并精準(zhǔn)調(diào)試。整個(gè)維修過程耗時(shí)三個(gè)半小時(shí)，期間每一步都需要精準(zhǔn)操作，比如門體起落時(shí)的平衡控制、新軸安裝的精準(zhǔn)對位，非人員根本無法完成，盲目拆解只會(huì)加重故障。

　　The maintenance of such faults is difficult and requires a professional team and standardized procedures to ensure stability and safety after repair. The proposed solution for this maintenance is to replace the entire transmission shaft and the deformed motor bracket plate. The specific steps are cumbersome and labor-intensive: the first step is to use an electric welding machine to blow up the hole of the transmission shaft and fit it into a steel pipe to fit the size; Slowly pull up and smoothly lower the door using a chain hoist to avoid secondary damage; Subsequently, the old transmission shaft that did not meet the standard length was dismantled and replaced with a new shaft that meets the standard length of 6.76 meters; Finally, replace the deformed bracket plate and make precise adjustments. The entire repair process takes three and a half hours, during which each step requires precise operation, such as balancing control during door lifting and precise alignment of new shaft installation. Non professionals cannot complete it at all, and blind disassembly will only aggravate the fault.

　　這起案例也給濟(jì)南電動(dòng)卷閘門用戶提了重要警示，除了規(guī)范操作，配件品質(zhì)與尺寸核查更是關(guān)鍵：，選購卷閘門時(shí)，要避開劣質(zhì)配件，務(wù)必要求商家提供配件規(guī)格說明，核對傳動(dòng)軸、軸心等核心部件的尺寸是否與門體匹配，拒絕“非標(biāo)配件湊合用”；其次，安裝環(huán)節(jié)要找團(tuán)隊(duì)，安裝后需檢查傳動(dòng)部件的配合度，確保運(yùn)行平穩(wěn)無偏移；日常使用中，若發(fā)現(xiàn)門體升降有異響、卡頓或輕微偏移，要立即停止使用并排查，避免小問題惡化成事故；另外，定期維護(hù)時(shí)要檢查傳動(dòng)軸、軸心、支架板等關(guān)鍵部件，發(fā)現(xiàn)磨損、變形或尺寸偏差及時(shí)更換。

　　This case also serves as an important warning to users of Jinan electric roller shutter doors. In addition to standardized operation, quality and size verification of accessories are crucial. Firstly, when purchasing roller shutter doors, it is important to avoid inferior accessories and require the merchant to provide specifications for the accessories. Check whether the dimensions of core components such as transmission shafts and shafts match the door body and refuse to use non-standard accessories; Secondly, a professional team should be sought during the installation process, and after installation, the fit of the transmission components should be checked to ensure smooth operation without deviation; In daily use, if there is any abnormal noise, jamming or slight deviation in the lifting of the door body, it should be immediately stopped and checked to avoid minor problems deteriorating into safety accidents; In addition, during regular maintenance, it is important to focus on inspecting key components such as transmission shafts, shafts, and support plates. If wear, deformation, or dimensional deviations are found, they should be replaced in a timely manner.

　　對濟(jì)南的企業(yè)和商戶而言，電動(dòng)卷閘門不僅是防護(hù)設(shè)施，更是保障運(yùn)營的重要屏障。很多故障的根源并非使用不當(dāng)，而是初期選購時(shí)的配件品質(zhì)隱患。建議大家在采購卷閘門時(shí)，不要只看，要優(yōu)先選擇配件規(guī)格標(biāo)準(zhǔn)、品質(zhì)有保障的正規(guī)產(chǎn)品，同時(shí)認(rèn)準(zhǔn)的安裝和維修團(tuán)隊(duì)。尤其是對大跨度、高頻使用的卷閘門，核心配件的品質(zhì)直接決定使用，切勿為了節(jié)省成本選擇劣質(zhì)非標(biāo)配件。

　　For enterprises and merchants in Jinan, electric rolling gates are not only protective facilities, but also important barriers to ensure operational safety. The root cause of many malfunctions is not improper use, but the quality hazards of accessories during the initial selection process. It is recommended that when purchasing roller shutter doors, one should not only consider the price, but also prioritize the selection of legitimate products with standardized accessory specifications and guaranteed quality. At the same time, it is important to identify professional installation and maintenance teams. Especially for large-span and high-frequency use of roller shutters, the quality of core accessories directly determines the safety of use. Do not choose inferior non-standard accessories to save costs.
