Description
本發明係與電梯有關；更詳而言之是指一種用於電梯升降井道且位於電梯機坑的爬梯。The invention relates to elevators; more particularly to a ladder for an elevator hoistway and located in an elevator pit.
已知電梯機坑位於電梯升降井道的最下方，該空間係供放置電梯的緩衝機構，因而須受到升降機安全檢查構造標準以及中華民國國家標準等相關法規規定限制其設置及使用方法。It is known that the elevator pit is located at the bottom of the elevator shaft, which is a buffer mechanism for the elevator. Therefore, it is subject to restrictions on the safety inspection structure of the elevator and the relevant regulations of the Republic of China and other national regulations.
電梯機坑屬於較危險且非一般人會經常出入的場所，通常電梯機坑僅有維修或檢查時，會有維修人員會進出於電梯機坑。其中，當維修人員欲進入電梯機坑時，為確保維修人員的安全，於法規中規定「當電梯機坑深度在1.4公尺以上時，必須裝設讓維修人員容易進出電梯機坑底部的固定爬梯，以供應維修人員進入機坑底部維修用使用」。而法規中所明定之固定爬梯係指永久設置於電梯底坑的爬梯；其中為確保使用該爬梯進出電梯機坑的人員安全，是故於法規中對於該爬梯也有相對應的規定，但不限制其爬梯是否為可伸縮長度或者固定長度。Elevator pits are places that are more dangerous and are not frequently accessed by ordinary people. Usually, when the elevator pit is only repaired or inspected, maintenance personnel will enter the elevator pit. Among them, when the maintenance personnel want to enter the elevator pit, in order to ensure the safety of the maintenance personnel, it is stipulated in the regulations that “when the elevator pit depth is more than 1.4 meters, the maintenance personnel must be installed and fixed at the bottom of the elevator pit. Ladders are used to supply maintenance personnel to the bottom of the pit for maintenance." The fixed ladder specified in the regulations refers to the ladder permanently installed in the elevator pit; in order to ensure the safety of the personnel entering and leaving the elevator pit using the ladder, there are corresponding provisions in the regulations for the ladder, but not limited. Whether the ladder is of a retractable length or a fixed length.
其中，在對爬梯的相關法規中，可得知垂直設立於電梯機坑的爬梯其橫擋背面與機坑牆壁之間應至少有200毫米的淨距離；爬梯高度於可供人員進出的使用狀態，全長應高於樓地面1.10公尺；且為方便使用者使用，入口及爬梯存放位置間的距離不得大於800毫米。Among them, in the relevant regulations on ladders, it can be known that the ladder vertically set up in the elevator pit should have a clear distance of at least 200 mm between the back of the crosspiece and the wall of the pit; the height of the ladder is in a state of use for personnel to enter and exit. The total length shall be 1.10 meters above the floor of the building; and for the convenience of the user, the distance between the entrance and the storage position of the ladder shall not exceed 800 mm.
其中，爬梯有可能為可收折、伸縮或斜靠，故法規定有當梯子被使用時，入口邊緣與梯子中間橫擋之間的最大距離應為600毫米。但爬梯若僅根據法規規定之距離設置於電梯底坑，會讓電梯升降井道的空間為了能夠容納讓電梯與爬梯，進而使電梯升降井道的空間需要更大的空間。Among them, the ladder may be foldable, telescopic or inclined, so the law stipulates that when the ladder is used, the maximum distance between the entrance edge and the middle rail of the ladder should be 600 mm. However, if the ladder is set in the elevator pit only according to the distance stipulated by the regulations, the space of the elevator shaft is required to accommodate the elevator and the ladder, so that the space of the elevator shaft is required to have more space.
有鑑於此，本發明之目的在於提供一種電梯機坑爬梯，係符合法規範且具有良好收納性以及良好的使用機動性，且不需另外增加電梯升降井道的空間。In view of the above, an object of the present invention is to provide an elevator pit ladder which conforms to the law and has good storability and good maneuverability, and does not require additional space for the elevator hoistway.

請配合圖４所示，該定著物10包含有一固定支架12、兩對第一樞軸14及兩對連接桿16，請再配合圖５以及圖６所示，其中連接桿16一端樞接該第一梯架20，另一端則透過第一樞軸14而與固定支架12樞接，使得第一梯架20可以藉由連接桿16相對於固定支架12樞擺於圖２所示之第一位置P1與圖８所示之第二位置P2之間。其中，連接桿16連接於固定支架12的一端具有一圓孔162及連通該圓孔162的一第一長槽孔164，而第一樞軸14的截面積為配合第一長槽孔164的長柱狀，當第一梯架20收折於固定支架12時，各該第一樞軸14分別位於各該第一長槽孔164中（圖６參照），使該第一梯架20不會在未受到控制的情況下，因外在因素（例如振動）而離開第一位置P1。As shown in FIG. 4 , the fixed object 10 includes a fixing bracket 12 , two pairs of first pivots 14 , and two pairs of connecting rods 16 . Please refer to FIG. 5 and FIG. 6 , wherein one end of the connecting rod 16 is pivotally connected. The first ladder frame 20 is pivotally connected to the fixed bracket 12 through the first pivot 14 so that the first ladder frame 20 can be pivoted relative to the fixed bracket 12 by the connecting rod 16 in FIG. A position P1 is between the second position P2 shown in FIG. The connecting rod 16 is connected to the fixing bracket 12 at one end thereof and has a circular hole 162 and a first long slot 164 communicating with the circular hole 162. The cross-sectional area of the first pivot 14 is matched with the length of the first long slot 164. In the column shape, when the first ladder frame 20 is folded on the fixing bracket 12, each of the first pivot shafts 14 is located in each of the first long slot holes 164 (refer to FIG. 6), so that the first ladder frame 20 does not Without being controlled, the first position P1 is left due to external factors such as vibration.
圖７所示為向上提拉梯架使得連接桿16上的圓孔162位置改變，即第一樞軸14改落於圓孔162中，接著將梯架往背離定著物10的方向拉出使得第一梯架20移動至圖８所示的第二位置P2。此外，值得一提的是，於本實施例中，所述第一樞軸14的上下兩側面係採取弧面設計，藉此，第一樞軸14在圓孔162中旋轉時，可以順暢地沿著圓孔162的內周面轉動。Figure 7 shows the upward lifting of the ladder frame so that the position of the circular hole 162 on the connecting rod 16 is changed, that is, the first pivot 14 is changed into the circular hole 162, and then the ladder frame is pulled away from the fixed object 10. The first ladder frame 20 is moved to the second position P2 shown in FIG. In addition, in the embodiment, the upper and lower sides of the first pivot 14 adopt a curved surface design, whereby the first pivot 14 can smoothly rotate when rotated in the circular hole 162. The inner peripheral surface of the circular hole 162 is rotated.
在上述中，當第一梯架20位於第一位置P1時，第一梯架20靠近於定著物10，且電梯機坑爬梯100呈收折狀態，此時，電梯最低樓層的入口及電梯機坑爬梯100存放位置間的距離小於800毫米。當第一梯架20位於第二位置P2時，第一梯架20與定著物10保持有第一距離L1，其中第一距離L1介於200毫米~600毫米之間（圖８參照）。In the above, when the first ladder frame 20 is at the first position P1, the first ladder frame 20 is close to the fixed object 10, and the elevator pit ladder 100 is in a folded state. At this time, the entrance of the lowest floor of the elevator and the elevator are The distance between the storage locations of the pit ladder 100 is less than 800 mm. When the first ladder frame 20 is at the second position P2, the first ladder frame 20 and the fixture 10 are maintained at a first distance L1, wherein the first distance L1 is between 200 mm and 600 mm (refer to FIG. 8 for reference).
更詳而言，第一梯架20受操控自第一位置P1移動至第二位置P2的過程係藉由使用者操控第一梯架20連同第二梯架30（圖６參照）往上提拉至第一轉換位置P5（圖７參照），此時連接桿16呈垂直狀態，且第一樞軸14由第一長槽孔164中脫離移動至圓孔162中，接著再操控第一梯架20連同第二梯架30以固定支架12為支點向外拉出使得第一梯架20位於第二位置P2（圖８參照），此時連接桿16以第一樞軸14為支點於圓孔162中轉動使連接桿16由垂直狀態樞擺為水平狀態。另外，於一實施例中，在固定架12可設置有一固定塊13，該固定塊13可供連接桿16承靠，藉此，於連接桿16樞轉至水平狀態時，可承靠在固定塊13上，藉以維持於水平狀態。但於其他實施例中，並不以此為限，舉例而言，亦可由第二梯架30移動至第二位置P2時，由第二梯架30底部承靠在滑台64上，以提供支撐效果。More specifically, the process of moving the first ladder frame 20 from the first position P1 to the second position P2 is performed by the user manipulating the first ladder frame 20 together with the second ladder frame 30 (refer to FIG. 6). Pulling to the first switching position P5 (refer to FIG. 7), the connecting rod 16 is in a vertical state, and the first pivot 14 is disengaged from the first long slot 164 into the circular hole 162, and then the first ladder is controlled. The frame 20 is pulled out with the second ladder frame 30 as a fulcrum with the fixed bracket 12 as a fulcrum such that the first ladder frame 20 is located at the second position P2 (refer to FIG. 8), and the connecting rod 16 is pivoted with the first pivot 14 as a fulcrum. Rotation in the aperture 162 pivots the connecting rod 16 from a vertical state to a horizontal state. In addition, in an embodiment, a fixing block 13 can be disposed on the fixing frame 12, and the fixing block 13 can be supported by the connecting rod 16, thereby supporting the fixing when the connecting rod 16 is pivoted to a horizontal state. At block 13, it is maintained at a level. However, in other embodiments, it is not limited thereto. For example, when the second ladder frame 30 is moved to the second position P2, the bottom of the second ladder frame 30 is supported on the sliding table 64 to provide Support effect.
請再配合圖５所示，該第一梯架20更包含有一對連接結構22，其中連接結構22分別具有二片立板222以兩兩相對的方式分別連接於第一梯架20頂部的管段，且各對立板222具有對應設置的二弧形槽孔224，且第二梯架30具有第二樞軸32，其中第二樞軸32穿過二弧形槽孔224，使第二梯架30得以連接於第一梯架20。前述弧形槽孔224包含有第一端224a以及第二端224b（圖６參照），當第二樞軸32位於弧形槽孔224的第一端224a時，第二梯架30以第二樞軸32為支點可受操控移動於圖８所示第三位置P3與圖10所示第四位置P4之間移動，且在第三位置P3與第四位置P4之間更經過第二轉換位置P6；更進一步地說，如圖９所示之第二梯架30被往上翻轉扳起且第二樞軸32仍位於弧形槽孔224的第一端224a時，第二梯架30來到第二轉換位置P6，此時，使用者只需再略為施力上提第二梯架30，使第二樞軸32順著弧形槽孔224移動到第二端224b即表示第二梯架30來到第四位置P4，並與第一梯架20呈上下對接狀態（圖10參照），且第二梯架30與第一梯架20因穩固對接而延長攀爬行程，以使得第二梯架30的頂端至最下方處電梯口的底緣保持有一第二距離L2，其中第二距離L2應高於樓地面1.10公尺，是故，第二距離L2大於第一距離L1。As shown in FIG. 5 , the first ladder frame 20 further includes a pair of connecting structures 22 , wherein the connecting structures 22 respectively have two vertical plates 222 connected to the pipe segments at the top of the first ladder frame 20 in opposite directions. And each of the opposing plates 222 has a correspondingly disposed two arcuate slots 224, and the second ladder frame 30 has a second pivot 32, wherein the second pivot 32 passes through the two arcuate slots 224, so that the second ladder frame 30 is connected to the first ladder frame 20. The arcuate slot 224 includes a first end 224a and a second end 224b (refer to FIG. 6). When the second pivot 32 is located at the first end 224a of the arcuate slot 224, the second ladder 30 is second. The pivot 32 is pivotally movable between the third position P3 shown in FIG. 8 and the fourth position P4 shown in FIG. 10, and the second switching position is further between the third position P3 and the fourth position P4. Further, when the second ladder frame 30 shown in FIG. 9 is flipped up and the second pivot 32 is still at the first end 224a of the arcuate slot 224, the second ladder frame 30 comes. To the second switching position P6, at this time, the user only needs to slightly lift the second ladder frame 30 to move the second pivot 32 along the curved slot 224 to the second end 224b, indicating the second ladder. The frame 30 comes to the fourth position P4 and is in an up-and-down state with the first ladder frame 20 (refer to FIG. 10), and the second ladder frame 30 and the first ladder frame 20 extend the climbing course due to the stable docking, so that the first The bottom edge of the elevator ladder at the top to the bottom of the second ladder frame 30 maintains a second distance L2, wherein the second distance L2 should be 1.10 meters higher than the floor surface, so the second distance L2 To the first distance L1.
以下說明第二梯架30得以與第一梯架20穩固對接的實現方式。請配合圖11至圖13所示，該第二梯架30包含有一對插管34、一對第二長槽孔36以及一對操縱桿38，其中，插管34設置於第二梯架30與第一梯架20相連接的部分，而操縱桿38的一端連接在插管34管體與第二長槽孔36相面對的一側，另一端則穿過第二長槽孔36，藉此使插管34得以受到使用者操控連接於操縱桿38上的扣接件382，而於第二長槽孔36長軸向的上始點362與下始點364之間移動，更進一步而言，第一梯架20更包含有第三樞軸24穿過連接結構22將連接桿16樞接於第一梯架20的上部管段，且插管34用以固定第二梯架30於第四位置P4，而藉由使用者將操縱桿38上的扣接件382分離第二梯架30，使操縱桿38由上始點362往下移動到下始點364，此時，插管34位移至第一梯架20頂部的管段與第二梯架30下部的管段之間，插管34會抵靠於第一梯架20中的第三樞軸24，且操縱桿38會抵於下始點364，避免插管34過度掉入第一梯架20內。在上述中，扣接件382可以是彈簧，彈簧的一端連接於操縱桿38，另一端則以勾扣方式勾抵於第二梯架30上的一穿孔30a，所述使扣接件382分離第二梯架30即是將彈簧一端與穿孔30a分離。在其他實施例中，扣接件382可以是簡單的勾具。An implementation in which the second ladder frame 30 is securely docked with the first ladder frame 20 is described below. As shown in FIG. 11 to FIG. 13 , the second ladder frame 30 includes a pair of cannula 34 , a pair of second long slot holes 36 , and a pair of operating levers 38 .
