In Fig. 3 and Fig. 4, the hoistway entrance [2] is set on the front wall of the hoistway [1], and the hoistway door [4] is arranged opposite to the hoistway entrance [2] and fixed on the hoistway [1] ] The hanger frame [3] on the front wall hangs down from the upper end. Car [9] can move vertically along two guide rails [7] fixed on the side wall of hoist room [1]. A floor sill [5] placed on the ground of each hoistway door guides the lower end of the hoistway door [4]. The car bottom beam [14] laid on the car bottom of the car [9] is opposite to the ground bottom beam [5] and guides the lower end of the car door [13], which is a double door type. The slotted member [6] is fixed on a car door [13] on the side of the front wall of the hoistway [1]. The projections [15] are inserted into the slots of the slotting element [6] so that the hoistway door [4] opens and closes together with the car door [13]. The rectangular car frame [8] supporting the car [9] includes two car mullions [8a] and the upper and lower car beams connecting the car mullions [8a] to each other at their upper and lower ends, respectively. Liang [8b] and [8c]. The guide shoe [16] engaged with the guide rail [7] is fixed on the upper and lower beams [8b] and [8c]. Braces [11] are secured to each car mullion [8a] and extend towards the front wall of the hoistway [1]. An L-shaped beam [12] is fixed on the bracing arm [11] and the car door [13] is suspended from the upper end of the L-shaped beam [12]. The adjustment steel rope of drive car [9] and running steel cable can be erected on a near guide rail [7].
按照本发明的检测轿厢位置的装置包括一个固定在吊架框[3]上的操作部件[30]和由固定在L形梁[12]上的电磁感应继电器制成的检测元件[38]。吊架框[3]与L形梁[12]的相对位置必须是很恰当的，因提升间门[4]同轿厢门[13]通过有槽的构件[6]和突出物[15]之间的啮合一起被打开和关闭。为此，操作部件[30]和检测元件[38]可以固定在装置（factory）的吊架框[3]和L形梁[12]上，而当它们安装时就不必调节它们彼此在提升间[1]内的相对位置。The device for detecting the position of the car according to the present invention includes an operating part [30] fixed on the hanger frame [3] and a detection element [38] made of an electromagnetic induction relay fixed on the L-shaped beam [12] . The relative position of the hanger frame [3] and the L-shaped beam [12] must be very appropriate, because the hoistway door [4] and the car door [13] pass through the grooved member [6] and the protrusion [15]. The meshing between them is opened and closed together. For this reason, the operating part [30] and the detection element [38] can be fixed on the hanger frame [3] and the L-shaped beam [12] of the plant (factory), and when they are installed, it is not necessary to adjust them to each other in the lifting space. Relative position within [1].
在与操作部件[30]和检测元件[38]的位置相符合的吊架框[3]的 一部分形成一纵向延展切口[3a]。在地面底梁[5]的一端形成一个与切口[3a]相对应的纵向延展切口[5a]。在轿厢底梁的一端形成一个纵向延伸切口[14a]。这切口[14a]与地面底梁[5]切口[5a]相对。In the position of the hanger frame [3] that matches the position of the operating part [30] and the detection element [38] One part forms a longitudinally extending incision [3a]. Form a longitudinal extension slit [5a] corresponding to the slit [3a] at one end of the ground bottom beam [5]. A longitudinally extending cut [14a] is formed at one end of the car bottom beam. This cutout [14a] is opposite with ground bottom beam [5] cutout [5a].
地面底梁[5]和轿厢底梁[14]之间的距离必须为30毫米左右。操作部件[30]插入检测元件[38]的凹槽部分的量必须是预先确定的长度，以使甚至在轿厢[9]振动时或当在操作部件[30]插入提升间[1]的量在各层之间有不同时，操作部件[30]仍会插入检测元件[38]中。地面底梁[5]和轿厢底梁[14]中的切口[5a]和[14a]分别以规定的尺寸制造，以便操作部件[30]按合适的量插到检测元件中。至少切口[5a]和[14a]之一允许检测元件[38]作垂直移动和操作部件[30]插入检测元件[38]的量是足够大的，在与操作部件[30]插入检测部件[38]中的量相称的或地面底梁[5]或轿厢底梁[14]中作出一个切口。吊架框[3]和L形梁[12]彼此接近，因而不必架设从上梁[8b]伸出的延伸部件等把工作部件[30]和检测元件[38]分别地安装到提升间[1]和轿厢[9]上。除了这个优点外，还有从主钢绳、靠近轿厢构架[8]的调整钢绳和驱动轿厢[9]的钢缆移开了操作部件[30]和检测元件[38]，以致各类钢绳和钢缆在振荡时不会碰在操作部件[30]和检测元件[38]上。因为驱动轿厢门[13]的接线是由L形梁[12]支撑，因此检测元件[38]的接线可以同驱动轿厢门[13]的接线一起进行。The distance between the ground bottom beam [5] and the car bottom beam [14] must be about 30 millimeters. The amount by which the operation part [30] is inserted into the groove portion of the detection element [38] must be a predetermined length so that even when the car [9] vibrates or when the operation part [30] is inserted into the hoistway [1] When the amount differs between layers, the operating part [30] is still inserted into the detection element [38]. The cutouts [5a] and [14a] in the ground bottom beam [5] and the car bottom beam [14] are manufactured with prescribed dimensions respectively so that the operating parts [30] are inserted into the detection element by a suitable amount. At least one of the cutouts [5a] and [14a] allows the detection element [38] to move vertically and the amount of insertion of the operation part [30] into the detection element [38] is large enough, when the operation part [30] is inserted into the detection part [ 38] or make a cut in the ground bottom beam [5] or car bottom beam [14] commensurate with the amount. The hanger frame [3] and the L-shaped beam [12] are close to each other, so there is no need to set up extension parts stretching out from the upper beam [8b], etc., and the working parts [30] and the detection element [38] are respectively installed in the lifting room [ 1] and car [9]. In addition to this advantage, there are operating parts [30] and detection elements [38] removed from the main steel rope, the adjustment steel rope near the car frame [8] and the steel cable driving the car [9], so that each Class steel ropes and steel cables will not bump into the operating part [30] and detection element [38] when vibrating. Because the wiring of the driving car door [13] is supported by the L-shaped beam [12], the wiring of the detection element [38] can be carried out together with the wiring of the driving car door [13].
在图5和6所示的第二实施方案中，在提升间[1]和轿厢[9]的侧边上的两扇都为一扇门类型提升间门[4′]和轿厢门[13′]分别地相当于在图3和图4中双门类型的门[4]和[13]。支撑构件[44]被固定在当门关闭时提升间门[4′]逼近的吊架框[3]的一部分上。L型操作部件[45]固定在支撑构件[44]上。一个支撑构件[46]被固定在与操作部件[45]相对的L形梁[12]的未端上。具有其中制成凹槽的检测元件[48]含有电磁感应继电器，并且固定在支撑构件[46]上。操作部件 [45]的一腿[45a]插入面向提升间[1]的侧壁的检测元件[48]的凹槽中。本结构在其它方面类似于图3和图4所示的第一实施方案那样的结构。In the second embodiment shown in Figures 5 and 6, both doors on the sides of the hoistway [1] and car [9] are a door type hoistway door [4'] and car door [13'] corresponds to the doors [4] and [13] of the double door type in Fig. 3 and Fig. 4, respectively. The support member [44] is secured to the part of the hanger frame [3] where the hoistway door [4'] approaches when the door is closed. The L-shaped operating part [45] is fixed on the supporting member [44]. A supporting member [46] is fixed on the end of the L-shaped beam [12] opposite to the operating part [45]. The detecting element [48] having the groove formed therein contains the electromagnetic induction relay and is fixed on the support member [46]. Operating parts One leg [45a] of [45] is inserted in the groove of the detection element [48] facing the side wall of the hoistway [1]. The structure is otherwise similar to that of the first embodiment shown in FIGS. 3 and 4 .
在图5和图6所示的实施方案中，当提升间门[4′]借助于轿厢门[13′]通过突出物[15]和开槽的构件[6]之间的啮合打开时，二扇门都被收进到各自的门接收部分中，该门接收部分的端部都是接近于在图5上端的提升间[1]的侧壁处。为此，提升间进口[2]和轿厢进口[10]的宽度都根据验定的提升间[1]的宽度设计成尽可能宽。但是，在图5的下端提升间的相对侧壁和用于打开和关闭门，其包括电机，减速装置等的常规设备之间必要的间隙是大约150-200毫米，以便能够安装导轨[7]。因此，当利用这个间隙时，易于把操作部件[45]通过支撑构件[44]固定于吊架框[3]和使检测元件[48]通过支撑构件[46]固定在L形梁[12]上。In the embodiment shown in Figures 5 and 6, when the hoistway door [4'] is opened by means of the car door [13'] through engagement between the protrusion [15] and the slotted member [6] , the two doors are all retracted into respective door receiving portions, the ends of which are all close to the side walls of the hoistway [1] at the upper end of FIG. 5 . For this reason, the width of the hoistway entrance [2] and the car entrance [10] is all designed to be as wide as possible according to the width of the hoistway [1] verified. However, the necessary clearance between the opposite side walls of the hoistway at the lower end of Fig. 5 and the conventional equipment for opening and closing the door, which includes motors, reduction gears, etc., is about 150-200 mm in order to be able to install guide rails [7] . Therefore, when utilizing this gap, it is easy to fix the operating part [45] to the hanger frame [3] through the support member [44] and to fix the detection element [48] to the L-shaped beam [12] through the support member [46]. superior.
如上所述，操作部件[45]和检测元件[48]最好安装在当门被关闭后这门逼近的侧壁上，但是，当它们安放在门接收部份和提升间[1]的另一侧壁之间的间隙内，可以获得同样和效果。As mentioned above, the operating part [45] and the detection element [48] are preferably installed on the side wall of the door approaching when the door is closed, but when they are placed on the other side of the door receiving part and the lift room [1] The same effect can be obtained in the gap between the side walls.
在以上所述的第一和第二实施方案中，检测元件包括电磁感应继电器，但是检测元件也能够是检测组合操作部件的光电管那样的元件。此外，操作部件是安装在提升间[1]的侧边，而检测元件安装在轿厢[9]的侧边，但是操作部件和检测元件可以分别地安装在轿厢[9]和提升间[1]的侧边上。In the above-described first and second embodiments, the detection element includes an electromagnetic induction relay, but the detection element can also be an element such as a photoelectric cell that detects a combined operation part. In addition, the operating parts are installed on the side of the lift room [1], and the detection elements are installed on the side of the car [9], but the operating parts and detection elements can be installed on the car [9] and the lift room [9] respectively. 1] on the side.
如上所述，根据本发明运行钢绳、主钢绳和调节钢缆等在振荡时不会绊在检测轿厢位置的部件上。并且，因为在现场安装前操作部件和检测元件可以固定在装备的各自支撑部件上，所以当它们安装时不必在提升间进行其对准，不必为部件和检测元件安装到各自的支撑部件上提供专门延展的部件，因此将减少部件的数量和它的费用。另外， 当至少在提升间和轿厢的侧面的相对部份之一制作切口使检测元件垂直地移动时，操作元件插入检测元件的量可以做得足够大。As described above, according to the present invention, the running wire rope, the main wire rope, the adjustment wire rope, etc. do not get caught on the parts for detecting the position of the car when they vibrate. Also, since the operating part and the detecting element can be fixed on the respective supporting parts of the equipment before being installed on site, it is not necessary to carry out their alignment in the hoisting room when they are installed, and it is not necessary to provide Specially extended parts, thus reducing the number of parts and its cost. in addition, When at least one of the opposing portions of the sides of the hoistway and the car is cut so that the detecting member moves vertically, the amount of insertion of the operating member into the detecting member can be made sufficiently large.
