Abstract

A method for preventing the elevator from an unexpected acceleration includes the following steps. A revolution monitoring means is provided to continually monitor the revolution of a hoisting motor during the elevator being operated. The power of the hoisting motor is taken off and a brake is operated when the elevator is moved to the intended position. At the same time, a controller judges that the brake is out of order when the revolution monitoring means monitors that the hoisting motor is not static, and the hoisting motor is operated to have a zero revolution to form a motor torque to stop the elevator. As a result, the hoisting motor is used as a brake device to stop the elevator and prevent the elevator from an unexpected acceleration for promoting the safety of the elevator when the brake is broken.

Description

電梯防暴衝方法及其結構Elevator anti-storming method and structure thereof

本發明係涉及一種電梯控制方法；特別是指一種電梯防暴衝之創新方法與結構技術揭示者。The invention relates to an elevator control method; in particular to an innovative method and structural technology revealer for an elevator anti-storm.

按，電梯是目前各種高樓大厦建築物環境中不可或缺的運輸設備，它帶給人們生活所需的便利性，但也隱藏著一定程度的危險性，此部份從近年來發生的一些電梯暴衝夾傷人甚至夾死人等意外事件即可瞭解。According to the elevator, the elevator is an indispensable transportation device in the environment of various high-rise buildings. It brings convenience to people's lives, but it also hides a certain degree of danger. This part has occurred in recent years. Elevator rushing to catch people and even pinching people and other accidents can be understood.

本發明所欲探討者，係為其中的電梯暴衝問題，而吾人認為電梯暴衝的原因，通常是煞車功能失效所致，煞車功能的失效會導致無法將電梯停住，此情況下，電梯車廂會因為載重情況的不同而產生向上或向下暴衝的狀態，因為根據電梯法規所訂內容，電梯車廂側規定乘載量需達額定載重一半時才會等於配重側的重量，所以當一、倆人乘坐電梯時，因配重側重量大於電梯車廂側，如果電梯電磁煞車無制動力時，依據槓桿原理該配重側會往下墜落，車廂則相對會往上暴衝；反之當電梯車廂為滿載量時，則會向下暴衝呈墜落狀態，所述暴衝過程中，其危險性主要是因為人員此時可能正好處於上下電梯的位置處(亦即位在電梯門中間)，所以當電梯暴衝而上下位移過程中，電梯與樓板相錯位時會造成人員被夾傷甚至因而喪命之嚴重事故。The inventor of the present invention is the elevator rush problem, and the reason that the elevator rush is usually caused by the failure of the brake function, the failure of the brake function may cause the elevator to be stopped, in this case, the elevator The car will be up or down due to different load conditions, because according to the regulations of the elevator regulations, the passenger car side must have a load capacity of half the rated load, which will equal the weight of the counterweight side. 1. When two people take the elevator, the weight of the counterweight is greater than the side of the elevator car. If the electromagnetic brake of the elevator has no braking force, the weight side will fall down according to the principle of the lever, and the carriage will be rushed upwards; When the elevator car is at full load, it will fall down and fall into a falling state. During the storming process, the danger is mainly because the personnel may just be at the position of the elevator up and down (that is, in the middle of the elevator door). Therefore, when the elevator rushes and moves up and down, the elevator and the floor are misaligned, which may cause a serious accident in which the person is pinched or even killed.

承上所述，電梯煞車功能的失效的原因大致有二，其一係電梯煞車機構產生機械性的卡死現象，進而導致煞車動作無法開啟或無法關閉；其二係為電梯之電控系統故障(如接點黏著、電磁煞車無法釋放、接點老舊損壞導致煞車卡鉗無法打開等等)。As mentioned above, there are two reasons for the failure of the elevator braking function. One of the series of elevator braking mechanisms produces mechanical jamming, which in turn causes the braking action to fail to open or close; the second is the elevator electronic control system failure. (If the contact is stuck, the electromagnetic brake cannot be released, the old contact is damaged, the brake caliper cannot be opened, etc.).

另查，目前雖然亦有業界研發出一種利用夾住鋼纜的方式來達到防止暴衝的結構型態者，惟此種習知電梯防暴衝技術於實際應用經驗中發現，其仍舊存在容易損壞鋼纜及相關構件之問題與缺弊，實仍非一理想實用之結構設計。In addition, although the industry has developed a structure that uses the method of clamping the steel cable to prevent overburden, the conventional anti-riot technology of the elevator has been found in practical application experience, and it still exists easily damaged. The problems and shortcomings of steel cables and related components are still not an ideal and practical structural design.

是以，針對上述習知電梯控制技術所存在之問題點，如何研發出一種能夠更具理想實用性之創新構造，使電梯能夠在面臨煞車功能失效的情況下，仍舊得以有效防止暴衝問題發生，實有待相關業界再加以思索突破之目標及重要技術課題。Therefore, in view of the problems existing in the above-mentioned conventional elevator control technology, how to develop an innovative structure that can be more ideal and practical, so that the elevator can effectively prevent the occurrence of the overburden problem in the case of the failure of the brake function. It is up to the relevant industry to think about the breakthrough goals and important technical issues.

有鑑於此，發明人本於多年從事相關產品之製造開發與設計經驗，針對上述之目標，詳加設計與審慎評估後，終得一確具實用性之本發明。In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

本發明之主要目的，係在提供一種電梯防暴衝方法，其所欲解決之技術問題，係針對如何研發出一種更具理想實用性之新式電梯防暴衝方法為目標加以思索創新突破。所述電梯係藉一鋼纜構件吊組於一曳引電動機，鋼纜構件另一端連接有一配重構件，另設有一煞車制動器以產生煞車作用，曳引電動機包括馬達及鋼纜拖曳輪，且曳引電動機係藉一控制器控制其運轉或停止狀態，進以控制電梯的升降或定位。The main object of the present invention is to provide an elevator anti-storming method, and the technical problem to be solved is to think about how to develop a new type of elevator anti-storming method which is more ideal and practical. The elevator is connected to a traction motor by a cable member, the other end of the cable member is connected with a weight member, and a brake is provided to generate a brake function, and the traction motor includes a motor and a cable tow wheel. And the traction motor controls the running or stopping state of the elevator by a controller to control the lifting or positioning of the elevator.

本發明解決問題之技術特點，主要在於該電梯防暴衝方法係包括：透過一馬達轉速監測手段，用以於該電梯使用過程中常態性監測該曳引電動機的馬達轉速狀態；於該電梯到達定位位置時，關閉曳引電動機之馬達使其停止運作，並啟動煞車制動器執行煞車動作；於所述電梯到達定位位置且煞車制動器執行煞車動作狀態下，此時若該馬達轉速監測手段所測得之馬達轉速不等於0，則控制器係判斷煞車制動器為故障，即令馬達啟動且控制其速度為0 ，從而產生一轉矩以定位電梯，藉此以防止電梯暴衝。The technical feature of the invention solves the problem, mainly that the elevator riot prevention method comprises: through a motor speed monitoring means, the motor speed state of the traction motor is normally monitored during the use of the elevator; and the elevator arrives at the position In the position, the motor of the traction motor is turned off to stop the operation, and the brake is activated to perform the braking operation; when the elevator reaches the positioning position and the brake is executed, the motor speed monitoring means detects the motor speed monitoring means. If the motor speed is not equal to 0, the controller determines that the brake is faulty, that is, the motor is started and its speed is controlled to be 0, thereby generating a torque to position the elevator, thereby preventing the elevator from overshooting.

本發明之主要效果與優點，係可有效解決煞車制動器故障時的問題，透過控制馬達轉速的方式，以將馬達作為煞車結構使用，使得電梯不致因為煞車制動器故障即發生暴衝夾人事故，進而達到大幅提昇電梯使用安全之實用進步性。The main effects and advantages of the present invention are that the problem of the brake brake failure can be effectively solved, and the motor is used as the brake structure by controlling the rotation speed of the motor, so that the elevator does not cause a violent collision accident due to the brake brake failure, and further Achieve the practical progress of greatly improving the safety of elevator use.

請參閱第1圖所示，係本發明電梯防暴衝方法之較佳實施例，惟此等實施例僅供說明之用，在專利申請上並不受此結構之限制；所述電梯10係藉由一鋼纜構件20吊組於一曳引電動機30，該鋼纜構件20之另一端連接有一配重構件40，另設有一煞車制動器50以產生煞車作用(註：例如對曳引電動機30 煞車)，該曳引電動機30包括一馬達31及一鋼纜拖曳輪32，且該曳引電動機30係藉由一控制器60控制其運轉或停止狀態，進以控制電梯10的升降或定位。Please refer to FIG. 1 , which is a preferred embodiment of the elevator riot prevention method of the present invention, but the embodiments are for illustrative purposes only, and are not limited by the structure in the patent application; A wire rope member 20 is hoisted to a traction motor 30. The other end of the wire rope member 20 is connected with a weight member 40, and a brake brake 50 is additionally provided to generate a braking effect. (Note: for example, the traction motor 30 The traction motor 30 includes a motor 31 and a cable towed wheel 32, and the traction motor 30 controls its operation or stop state by a controller 60 to control the lifting or positioning of the elevator 10.

請配合第1、2圖所示，該電梯防暴衝方法係包括下述： a、透過一馬達轉速監測手段，用以於該電梯10使用過程中常態性監測該曳引電動機30的馬達31轉速狀態；所述馬達轉速監測手段具體實現上可透過設置後文所述馬達轉速監測器70的方式具體達成； b、於該電梯10到達定位位置(即各樓層位置)時，關閉曳引電動機30之馬達31使其停止運作，並啟動煞車制動器50執行煞車動作； c、於所述電梯10到達定位位置且煞車制動器50執行煞車動作狀態下，此時若該馬達轉速監測手段所測得之馬達31轉速不等於0，則控制器60係判斷煞車制動器50為故障，即令馬達31啟動且控制其速度為0 ，從而產生一轉矩以定位電梯10，藉此以防止電梯10暴衝。Please cooperate with the first and second figures, the elevator riot prevention method includes the following: a. Through a motor speed monitoring means, the motor 31 of the traction motor 30 is normally monitored for the normal operation of the elevator 10 during use. The motor speed monitoring means can be specifically realized by setting the motor speed monitor 70 described later; b. when the elevator 10 reaches the positioning position (ie, each floor position), the traction motor 30 is turned off. The motor 31 stops the operation, and activates the brake brake 50 to perform the braking operation; c. when the elevator 10 reaches the positioning position and the brake brake 50 performs the braking operation state, the motor measured by the motor rotation speed monitoring means at this time If the rotational speed is not equal to 0, the controller 60 determines that the brake brake 50 is faulty, that is, causes the motor 31 to start and controls its speed to be zero, thereby generating a torque to position the elevator 10, thereby preventing the elevator 10 from overshooting.

如第1圖所示，其中該方法並可包括一電梯門狀態偵測手段(圖面未標示)，當該控制器60判斷煞車制動器50為故障時，係先透過該電梯門狀態偵測手段偵測電梯門11是否關閉，若偵測電梯門11為尚未關閉狀態，判斷人員為未脫困，即令馬達31啟動且控制其速度為0 ，從而產生一轉矩以定位電梯10；若偵測電梯門11為關閉狀態，判斷人員為安全狀態，控制器60得令馬達31加速運轉將電梯10拉引至設定最頂樓位置(如第3圖所示狀態，亦即使配重構件40相對落到低點位置)，並打開電梯門11讓受困人員離開電梯10，經一設定脫困時間後，令電梯門11關閉，並於偵測電梯門11為關閉狀態後關閉馬達31使其停止運作，再透過馬達轉速監測手段監測馬達31轉速，以判斷煞車制動器50是否恢復正常，若煞車制動器50故障，電梯10得被配重構件40所牽引上升至一設定最高點位置而停止，令其不再有任何動作等待人員故障排除，若判斷煞車制動器50正常，則恢復電梯10正常使用狀態。As shown in FIG. 1 , the method may include an elevator door state detecting means (not shown). When the controller 60 determines that the brake brake 50 is faulty, the controller first passes the elevator door state detecting means. Detecting whether the elevator door 11 is closed or not, if it is detected that the elevator door 11 is not closed, it is judged that the person is not getting out of sleep, that is, the motor 31 is started and its speed is controlled to be 0, thereby generating a torque to locate the elevator 10; The door 11 is in a closed state, and the person is judged to be in a safe state. The controller 60 has to accelerate the operation of the motor 31 to pull the elevator 10 to the set topmost position (as shown in Fig. 3, even if the weight member 40 is relatively falling The low position is opened, and the elevator door 11 is opened to allow the trapped person to leave the elevator 10. After the set time is removed, the elevator door 11 is closed, and after the elevator door 11 is detected to be in the closed state, the motor 31 is turned off to stop the operation. The motor 31 speed is monitored by the motor speed monitoring means to determine whether the brake brake 50 is restored to normal. If the brake brake 50 is faulty, the elevator 10 is pulled by the weight member 40 to a set maximum position and stopped. So that it no longer has any person waiting troubleshooting action, determining if the normal brake brake 50, the elevator 10 to restore the normal state.

前段實施例中，控制器60令電梯10拉引至最頂樓位置的好處是讓配重構件40能夠相對下降至較低點位置處，如此一來可避免配重構件40從過高處下墜而容易造成相關構件(如緩衝器)損壞的問題發生，安全性也相對較高。In the previous embodiment, the advantage of the controller 60 pulling the elevator 10 to the topmost position is that the weight member 40 can be relatively lowered to a lower point position, thus avoiding the weight member 40 from being too high. It is easy to cause damage to related components (such as shock absorbers) and the safety is relatively high.

As shown in FIG. 1 , the elevator anti-riot structure comprises: a motor rotation speed monitor 70 for normally monitoring the traction motor during use of the elevator 10 . a motor 31 rotational speed state; a controller 60 electrically coupled to the motor 31 of the traction motor 30, the motor speed monitor 70, and the brake brake 50; and wherein the controller 60 is closed when the elevator 10 reaches the positioning position The motor 31 of the traction motor 30 is stopped to operate, and the brake brake 50 is activated to perform the braking operation, and when the elevator 10 reaches the positioning position and the brake brake 50 performs the braking operation state, at this time, if the motor rotation speed monitor 70 measures If the motor 31 speed is not equal to 0, the controller 60 determines that the brake brake 50 is faulty, that is, the motor 31 is started and its speed is controlled to be 0, thereby generating a torque to position the elevator 10, thereby preventing the elevator 10 from rushing. .

補充說明的是：所述馬達轉速監測手段的具體實現，係可令該曳引電動機30的馬達31係採用交流馬達裝設編碼器，或者直接採用伺服馬達，如此即可具體達到監測馬達31轉速狀態之功能。It is to be noted that the specific implementation of the motor speed monitoring means enables the motor 31 of the traction motor 30 to be equipped with an AC motor or an encoder motor, so that the speed of the monitoring motor 31 can be specifically achieved.
