Description

电梯设备elevator equipment

技术领域 technical field

本发明涉及一种不设置机械室的电梯设备。The invention relates to an elevator installation without a machine room.

背景技术 Background technique

在现有的电梯设备中，例如像日本特开2007-297209号公报(专利文献1)中所记载的那样，构成如下结构，即，电梯轿厢和平衡重的悬吊负载作用在主吊索固定基座的相反侧的电梯轿厢导轨、平衡重导轨、安装在顶部横梁上的顶部绳轮以及主吊索端部上，该悬吊负载由电梯轿厢侧导轨、平衡重导轨以及顶部横梁支承柱支承，其中，所述顶部横梁固定在所述顶部横梁支承柱的上部。并且，平衡重导轨固定在电梯坑基座的上表面，顶部横梁支承柱经由卷扬机固定基座固定在电梯坑基座的上表面，因此，作用在位于最下层附近的卷扬机绳轮上的朝上方拉起的力由平衡重导轨以及顶部横梁支承柱来承受。从除作用在电梯轿厢主吊索固定基座上的负载以外的悬吊负载、卷扬机绳轮的上拉负载、支承这些负载的导轨及顶部横梁支承柱之间的位置关系来看，一部分负载的作用位置超出了以连结主吊索固定基座的相反侧的电梯轿厢导轨和主吊索固定基座侧平衡重导轨的直线为一条边并且以顶部横梁支承柱为其他两条边的三角形，进而，主吊索固定基座侧平衡重导轨和顶部横梁支承柱只竖立地设置到顶部横梁的下表面，而并没有竖立地设置到升降通道的顶部。In conventional elevator equipment, as described in Japanese Unexamined Patent Application Publication No. 2007-297209 (Patent Document 1), for example, it is configured such that the suspension load of the elevator car and the counterweight acts on the main ropes. The elevator car guide rails on the opposite side of the fixed base, the counterweight guide rails, the top sheave mounted on the top beam and the end of the main sling, the suspended load is composed of the elevator car side guide rails, the counterweight guide rails and the top beam The support column is supported, wherein the top beam is fixed on the upper part of the top beam support column. And, the counterweight guide rail is fixed on the upper surface of the elevator pit base, and the top beam support column is fixed on the upper surface of the elevator pit base via the hoist fixing base, so the upward direction acting on the hoist sheave located near the lowermost layer The pull-up force is borne by the counterweight guide rail and the top beam support column. From the point of view of the suspension load other than the load acting on the fixed base of the main sling of the elevator car, the pull-up load of the hoist sheave, the positional relationship between the guide rails supporting these loads and the support column of the top beam, a part of the load The action position exceeds the triangle with the straight line connecting the elevator car guide rail on the opposite side of the main sling fixed base and the counterweight guide rail on the side of the main sling fixed base as one side and the top beam support column as the other two sides , and furthermore, the main sling fixing base side counterweight guide rail and the top crossbeam support column are only vertically provided to the lower surface of the top crossbeam, but are not vertically provided to the top of the hoistway.

专利文献1：日本特开2007-297209号公报Patent Document 1: Japanese Unexamined Patent Publication No. 2007-297209

在上述现有的电梯设备中，从除作用在电梯轿厢主吊索固定基座上的负载以外的悬吊负载及卷扬机绳轮的上拉负载与支承这些负载的导轨以及顶部横梁支承柱之间的位置关系来看，一部分负载的作用位置超出了以连结主吊索固定基座的相反侧的电梯轿厢导轨和主吊索固定基座侧平衡重导轨的直线为一条边并且以顶部横梁支承柱为其他两条边的三角形。因此，在超出三角形这一侧的导轨或者支承柱上作用有压缩负载，而在与上述超出侧相反的一侧的导轨或者支承柱上则作用有拉伸负载，从而，使得负载出现集中在一部分的导轨或者支承柱上的倾向，由此，需要增强上述导轨以及支承柱的强度，从而有可能导致制造成本上升。此外，由于主吊索固定基座侧平衡重导轨以及顶部横梁支承柱没有竖立地设置到升降通道的顶部，因此，在采用钢结构等的建筑物中，通过导轨支架将导轨以及顶部横梁支承柱能够固定在建筑物上的高度必须设定在顶部横梁的下方，从而存在需要增设中间横梁或紧固板等构件的问题。In the conventional elevator equipment described above, the suspension load other than the load acting on the fixed base of the main rope of the elevator car and the pull-up load of the hoisting sheave, and the guide rails supporting these loads and the support column of the top beam From the point of view of the positional relationship between them, the acting position of a part of the load exceeds the line connecting the elevator car guide rail on the opposite side of the main sling fixed base and the counterweight guide rail on the side of the main sling fixed base as one side and the top beam The support column is a triangle with the other two sides. Therefore, a compressive load acts on the guide rail or support column on the side beyond the triangle, and a tensile load acts on the guide rail or support column on the side opposite to the above-mentioned excess side, so that the load appears to be concentrated in one part. The tendency on the guide rails or support columns, therefore, the strength of the above-mentioned guide rails and support columns needs to be enhanced, which may lead to an increase in manufacturing costs. In addition, since the main sling fixed base side counterweight guide rail and the top beam support column are not vertically installed on the top of the hoistway, in buildings using steel structures, etc., the guide rail and the top beam support column The height that can be fixed on the building must be set below the top beam, so there is a problem that members such as intermediate beams and fastening plates need to be added.

发明内容 Contents of the invention

本发明是为了解决上述问题而作出的，其目的在于提供一种电梯设备，其借助较简单的结构，无需增加导轨的强度，而能够降低成本。The present invention was made in order to solve the above problems, and an object of the present invention is to provide an elevator system capable of reducing costs by virtue of a relatively simple structure without increasing the strength of the guide rail.

在本发明的电梯设备中，使包括安装于顶部横梁的绳轮上的负载作用点和卷扬机的绳轮上的负载作用点的负载作用点位于由支承这些负载的导轨和顶部横梁支承柱围成的虚拟多边形内。In the elevator equipment of the present invention, the load application point including the load application point installed on the sheave of the top beam and the load application point on the sheave of the hoisting machine is located in the area surrounded by the guide rails and the top beam support column supporting these loads. within the virtual polygon.

根据本发明，由于能够抑制作用在导轨和顶部横梁支承柱上的负载集中在局部，所以不需要增强导轨和顶部横梁支承柱的强度，也不需要加大导轨和顶部横梁支承柱的尺寸。According to the present invention, since local concentration of the load acting on the guide rail and the top beam support column can be suppressed, there is no need to increase the strength of the guide rail and the top beam support column, and it is not necessary to increase the size of the guide rail and the top beam support column.

平衡重3位于电梯轿厢2的背部，也就是位于电梯轿厢门30侧的相反侧和与其对置的升降通道壁面之间的空间内。卷扬机4也位于相同的空间内，该卷扬机4相对于主吊索固定基座的相反侧的导轨17，在平衡重3的相反侧固定设置在升降通道内的最下层地板高度附近。绳轮不通过减速齿轮而直接安装在卷扬机4的电动机部的旋转轴上。该绳轮设置在卷扬机主体上，位于卷扬机的靠电梯轿厢2的一侧。The counterweight 3 is located at the back of the elevator car 2, that is, in the space between the opposite side of the elevator car door 30 side and the wall of the hoistway opposite to it. Hoist 4 is also located in the same space, and this hoist 4 is fixedly arranged near the lowermost floor level in the hoistway on the opposite side of counterweight 3 with respect to the guide rail 17 on the opposite side of the main sling fixed base. The sheave is directly attached to the rotating shaft of the motor portion of the hoist 4 without passing through a reduction gear. The sheave is arranged on the main body of the hoist and is positioned at the side of the hoist near the elevator car 2 .

当驱动卷扬机4时，电梯轿厢2在主吊索固定基座6侧的导轨即主吊索固定基座侧电梯轿厢导轨13、以及主吊索5从电梯轿厢下部绳轮7朝向电梯轿厢侧顶部绳轮8a、8b延伸的一侧的导轨即主吊索固定基座的相反侧的电梯轿厢导轨14的引导下升降，平衡重3在平衡重主吊索固定基座11侧的导轨即主吊索固定基座侧平衡重导轨16、以及主吊索5从平衡重的绳轮朝向顶部平衡重侧绳轮10延伸的一侧的导轨即主吊索固定基座的相反侧的平衡重导轨17的引导下朝着与电梯轿厢2相反的方向升降。When the hoist 4 is driven, the guide rail of the elevator car 2 on the side of the main sling fixed base 6 is the elevator car guide rail 13 on the side of the main sling fixed base, and the main sling 5 moves toward the elevator from the lower sheave 7 of the elevator car. The guide rail on the side where the top sheaves 8a and 8b extend on the side of the car is guided by the elevator car guide rail 14 on the opposite side of the main sling fixed base, and the counterweight 3 is on the side of the counterweight main sling fixed base 11 The guide rail of the main sling fixed base side counterweight guide rail 16, and the guide rail of the side where the main sling 5 extends from the sheave of the counterweight toward the top counterweight side sheave 10 is the opposite side of the main sling fixed base Under the guidance of the counterweight guide rail 17 of the elevator car, it goes up and down in the direction opposite to the elevator car 2.

电梯轿厢侧主吊索固定基座6、电梯轿厢侧顶部绳轮8a、8b、平衡重侧顶部绳轮10以及平衡重侧主吊索固定基座11上作用有电梯轿厢2和平衡重3的悬吊负载，另一方面，卷扬机4的绳轮上作用有朝向上方的上拉负载。悬吊负载由固定在位于升降通道底面的电梯轿厢侧电梯坑基座15的上表面的电梯轿厢导轨13、14、固定在位于升降通道底面的平衡重侧电梯坑19的上表面的主吊索固定基座侧平衡重导轨16、主吊索固定基座的相反侧的平衡重导轨17以及顶部横梁支承柱18支承。此外，连结主吊索固定基座的相反侧的导轨14和顶部横梁支承柱18的虚拟直线与相邻的升降通道壁面平行。也就是说，电梯轿厢侧顶部横梁9在其长度方向上与相邻的升降通道壁面平行。另外，连结主吊索固定基座侧平衡重导轨16和顶部横梁支承柱18的虚拟直线与相邻的升降通道壁面平行。也就是说，平衡重侧顶部横梁12a、12b在其长度方向上与相邻的升降通道壁面平行。The elevator car side main sling fixing base 6, the elevator car side top sheave 8a, 8b, the counterweight side top sheave 10 and the counterweight side main sling fixing base 11 act on the elevator car 2 and the balancer. On the other hand, the suspension load of the weight 3 acts on the sheave of the hoist 4, and the upward pulling load acts on it. The suspended load is fixed on the elevator car guide rails 13, 14 on the upper surface of the elevator car side elevator pit base 15 located at the bottom surface of the hoistway, and the main rails 13 and 14 fixed on the upper surface of the counterweight side elevator pit 19 located at the bottom surface of the hoistway. The counterweight guide rail 16 on the side of the sling fixing base, the counterweight guide rail 17 on the opposite side of the main sling fixing base, and the top beam support column 18 are supported. In addition, an imaginary straight line joining the guide rail 14 on the opposite side of the main sling anchorage base and the top beam support column 18 is parallel to the adjacent hoistway wall. That is to say, the elevator car side top cross beam 9 is parallel to the wall surface of the adjacent hoistway in its length direction. In addition, the imaginary straight line connecting the counterweight guide rail 16 on the fixed base side of the main sling and the top beam support column 18 is parallel to the wall surface of the adjacent hoistway. That is to say, the top beams 12a, 12b on the counterweight side are parallel to the adjacent walls of the lifting passage in the length direction.

电梯轿厢导轨13、14、平衡重导轨16、17和顶部横梁支承柱18通过导轨支架20a～20d被牢固地固定在建筑物的紧固板21a～21d或者建筑物的横梁22a～22d等上(参照图3)。The elevator car guide rails 13, 14, the counterweight guide rails 16, 17 and the top beam support column 18 are firmly fixed on the fastening plates 21a-21d of the building or the beams 22a-22d of the building through the guide rail brackets 20a-20d. (Refer to Figure 3).

电梯轿厢侧顶部横梁9由长条状构件构成，其两端部分分别固定在主吊索固定基座的相反侧的电梯轿厢导轨14的顶部和顶部横梁支承柱18的顶部，使得电梯轿厢侧顶部横梁9的长度方向与电梯轿厢的进深方向平行。平衡重侧顶部横梁12a、12b由二根长条状构件构成，其两端部分分别固定在主吊索固定基座侧平衡重导轨16和顶部横梁支承柱18的顶部，使得这二根长条状构件的长度方向分别与位于电梯轿厢2背部的升降通道壁面平行。电梯轿厢侧顶部横梁9和平衡重侧顶部横梁12a、12b设置在升降通道内的角部，形成为近似为直角的大致L字形状。此外，在本实施方式中，平衡重侧顶部横梁由二个构件构成，但也可以由一个构件构成。The top beam 9 on the side of the elevator car is made of a strip-shaped member, and its two ends are respectively fixed on the top of the elevator car guide rail 14 and the top of the top beam support column 18 on the opposite side of the main sling fixed base, so that the elevator car The longitudinal direction of the car side top beam 9 is parallel to the depth direction of the elevator car. The top crossbeam 12a, 12b on the counterweight side is made of two strip-shaped members, and its two ends are respectively fixed on the top of the main sling fixed base side counterweight guide rail 16 and the top crossbeam supporting column 18, so that the two long strips The longitudinal directions of the shaped members are respectively parallel to the walls of the hoistway at the back of the elevator car 2 . The elevator car-side roof beam 9 and the counterweight-side roof beams 12a, 12b are provided at corners in the hoistway, and are formed in an approximately right-angled substantially L-shape. In addition, in the present embodiment, the counterweight-side roof beam is composed of two members, but it may be composed of one member.

如图2所示，电梯轿厢侧顶部绳轮8a、8b、平衡重侧顶部绳轮10、平衡重侧主吊索固定基座6、用于安装这些构件的电梯轿厢侧顶部横梁9以及平衡重侧顶部横梁12a、12b在平面上位于与主吊索固定基座的相反侧的电梯轿厢导轨14、主吊索固定基座侧平衡重导轨16以及顶部横梁支承柱18错开的位置，因此，能够将主吊索固定基座的相反侧的电梯轿厢导轨14、主吊索固定基座侧平衡重导轨16以及顶部横梁支承柱18竖立地设置到升降通道的顶部。由此，即使在采用钢结构等的建筑物中，也能够方便地将导轨支架20安装在建筑物的位于升降通道顶部的横梁和紧固板等上，所以不需要在顶部横梁的下方增设中间横梁等。As shown in Figure 2, the elevator car side top sheave 8a, 8b, the counterweight side top sheave 10, the counterweight side main sling fixing base 6, the elevator car side top beam 9 for installing these components and The top crossbeams 12a and 12b on the counterweight side are located at positions staggered from the elevator car guide rail 14 on the opposite side of the main sling fixing base, the counterweight guide rail 16 on the side of the main sling fixing base and the top crossbeam support column 18 on the plane, Therefore, the elevator car guide rail 14 on the opposite side of the main rope fixing base, the counterweight guide rail 16 on the main rope fixing base side, and the top beam support column 18 can be vertically installed on the top of the hoistway. As a result, even in buildings with steel structures, the guide rail bracket 20 can be easily installed on the beams and fastening plates at the top of the building, so there is no need to add an intermediate frame under the top beams. Beams etc.

如图2所示，电梯轿厢侧顶部绳轮8a、8b安装在电梯轿厢侧顶部横梁9的靠电梯轿厢的一侧。此外，电梯轿厢侧顶部横梁9在靠该电梯轿厢的一侧，与主吊索固定基座的相反侧的电梯轿厢导轨14以及顶部横梁支承柱18的背面连接。从图2所示的升降通道的水平剖面观察时，主吊索固定基座侧平衡重导轨16、平衡重侧主吊索固定基座11、平衡重的绳轮、平衡重侧顶部绳轮10、主吊索固定基座的相反侧的平衡重导轨17、卷扬机4的绳轮以及顶部横梁支承柱18按照上述顺序沿着平衡重侧顶部横梁12a、12b即二根长条状构件的长度方向设置，并且位于这些长条状构件之间。其中，平衡重侧顶部绳轮10固定在平衡重侧顶部横梁12a、12b上。As shown in Figure 2, the elevator car side top sheaves 8a, 8b are installed on the side of the elevator car side top beam 9 close to the elevator car. In addition, the elevator car side roof beam 9 is connected to the back side of the elevator car guide rail 14 and the roof beam support column 18 on the side opposite to the main rope fixing base on the side of the elevator car. When viewed from the horizontal section of the hoistway shown in Figure 2, the main sling fixed base side counterweight guide rail 16, the counterweight side main sling fixed base 11, the sheave of the counterweight, and the top sheave 10 on the counterweight side 1. The counterweight guide rail 17 on the opposite side of the main sling fixed base, the sheave of the hoist 4 and the top beam support column 18 follow the length direction of the top beam 12a, 12b on the counterweight side, that is, the two long strip members in the above order Set, and located between these strip-shaped components. Wherein, the top sheave 10 on the balance weight side is fixed on the top beams 12a, 12b on the balance weight side.

在图2所示的零件和构件以及设备的设置方法中，电梯轿厢侧顶部绳轮8a、8b的悬吊负载的负载作用点与电梯轿厢侧顶部横梁9相比，也就是与连结主吊索固定基座的相反侧的电梯轿厢导轨14和顶部横梁支承柱18的虚拟直线相比，更靠近电梯轿厢侧。此外，作用在卷扬机4的绳轮上的上拉负载的负载作用点以及平衡重侧顶部绳轮10和平衡重侧主吊索固定基座11上的悬吊负载的负载作用点与连结主吊索固定基座侧平衡重导轨16和顶部横梁支承柱18的虚拟直线相比，更靠近电梯轿厢侧。In the parts and components and the installation method of the equipment shown in Fig. 2, the load action point of the suspension load of the elevator car side top sheave 8a, 8b is compared with the elevator car side top beam 9, that is, the connection main The elevator car guide rail 14 on the opposite side of the sling fixing base is closer to the elevator car side than the virtual straight line of the top beam support column 18 . In addition, the load action point of the pull-up load acting on the sheave of the winch 4 and the load action point of the suspension load on the top sheave 10 on the counterweight side and the main sling fixing base 11 on the counterweight side are connected to the main hoist The cable fixing base side counterweight guide rail 16 is closer to the elevator car side than the virtual straight line of the top beam support column 18 .

具体来说是，从除作用在电梯轿厢主吊索固定基座6上的负载以外的悬吊负载、卷扬机4的绳轮的上拉负载与支承这些负载的主吊索固定基座的相反侧的导轨14、主吊索固定基座侧平衡重导轨16以及顶部横梁支承柱18之间的位置关系来看，所有的负载的作用位置均位于以连结主吊索固定基座的相反侧的电梯轿厢导轨14和主吊索固定基座侧平衡重导轨16的虚拟直线为一条边并且以顶部横梁支承柱18为其他两条边的三角形中，并位于除电梯轿厢2的水平投影以外的范围内。Specifically, from the suspension load other than the load acting on the main rope fixing base 6 of the elevator car, the pull-up load of the sheave of the hoist 4 is opposite to that of the main rope fixing base supporting these loads. From the perspective of the positional relationship between the side guide rail 14, the side counterweight guide rail 16 of the main sling fixed base, and the top beam support column 18, all loads are located on the opposite side of the main sling fixed base. The virtual straight line of the elevator car guide rail 14 and the main sling fixed base side counterweight guide rail 16 is one side and the triangle with the top beam support column 18 as the other two sides, and is located outside the horizontal projection of the elevator car 2 In the range.

在此，以平衡重侧顶部绳轮10的悬吊负载为例，参照图4进行说明。在图4中，平衡重侧顶部绳轮10上的负载作用点位于以连结主吊索固定基座的相反侧的电梯轿厢导轨14和主吊索固定基座侧平衡重导轨16的虚拟直线为一条边并且以顶部横梁支承柱18为其他两条边的三角形中，因此，各个负载都是朝下方作用的负载，从而能够抑制负载在局部集中。由此，可以抑制力过度地集中在一根导轨或者顶部横梁支承柱18上的情况发生，所以不需要增大导轨和顶部横梁支承柱的尺寸，从而能够抑制制造成本。并且，在连结主吊索固定基座的相反侧的电梯轿厢导轨14的背面和顶部横梁支承柱18的背面的虚拟直线与升降通道侧壁面平行时，能够使电梯轿厢侧顶部横梁9的结构变得更为简单，为此能够降低成本。Here, taking the suspended load of the top sheave 10 on the counterweight side as an example, it will be described with reference to FIG. 4 . In Fig. 4, the load application point on the top sheave 10 on the counterweight side is located on a virtual straight line connecting the elevator car guide rail 14 on the opposite side of the main sling fixed base and the counterweight guide rail 16 on the main sling fixed base side In a triangle having one side and the top beam support column 18 as the other two sides, each load is a load acting downward, and local concentration of the load can be suppressed. This suppresses excessive concentration of force on one guide rail or the roof beam support column 18, so that the size of the guide rails and the roof beam support column does not need to be increased, and manufacturing costs can be suppressed. And, when the imaginary straight line connecting the back side of the elevator car guide rail 14 on the opposite side of the main rope fixing base and the back side of the top beam support column 18 is parallel to the side wall surface of the hoistway, the top beam 9 on the side of the elevator car can be The structure becomes simpler, and thus the cost can be reduced.

图5是表示本发明的电梯设备的另一实施方式的俯视图。与图1相同的构件采用相同的符号表示。在本实施例中，除了图1的实施方式的结构以外，还在升降通道的顶部通过电梯轿厢主吊索固定基座侧顶部横梁23来连接主吊索固定基座侧电梯轿厢导轨13和主吊索固定基座侧平衡重导轨16，并在该电梯轿厢主吊索固定基座侧顶部横梁23上安装了电梯轿厢侧主吊索固定基座6。连结主吊索固定基座侧电梯轿厢导轨13和主吊索固定基座侧平衡重导轨16的虚拟直线和与其相邻的升降通道壁面平行。也就是说，电梯轿厢主吊索固定基座侧顶部横梁23被设置成在其长度方向上与相邻的升降通道壁面平行。Fig. 5 is a plan view showing another embodiment of the elevator equipment of the present invention. The same components as those in Fig. 1 are denoted by the same symbols. In this embodiment, in addition to the structure of the embodiment shown in FIG. 1 , the elevator car guide rail 13 on the side of the main sling fixing base is connected to the top beam 23 on the side of the main sling fixing base of the elevator car at the top of the hoistway. And main sling fixed base side counterweight guide rail 16, and on this elevator car main sling fixed base side top beam 23, elevator car side main sling fixed base 6 was installed. The imaginary straight line connecting main sling fixed base side elevator car guide rail 13 and main sling fixed base side counterweight guide rail 16 is parallel to the hoistway wall surface adjacent to it. That is to say, the top beam 23 on the side of the fixing base of the main sling of the elevator car is arranged to be parallel to the wall surface of the adjacent hoistway in its length direction.

电梯轿厢侧顶部绳轮8a、8b、平衡重侧顶部绳轮10、平衡重侧主吊索固定基座11、用来安装这些构件的电梯轿厢侧顶部横梁9、平衡重侧顶部横梁12a、12b以及电梯轿厢主吊索固定基座侧顶部横梁23在平面上位于与主吊索固定基座侧电梯轿厢导轨13、主吊索固定基座的相反侧的电梯轿厢导轨14、主吊索固定基座侧平衡重导轨16以及顶部横梁支承柱18错开的位置。因此，主吊索固定基座侧电梯轿厢导轨13、主吊索固定基座的相反侧的电梯轿厢导轨14、主吊索固定基座侧平衡重导轨16以及顶部横梁支承柱18能够竖立地设置到升降通道的顶部，因此，与上述实施方式一样地，即使在采用钢结构等的建筑物中，也能够方便地将导轨支架安装在建筑物的位于升降通道顶部的横梁和紧固板等上，所以不需要在顶部横梁的下方增设中间横梁等。Elevator car side top sheave 8a, 8b, counterweight side top sheave 10, counterweight side main sling fixing base 11, elevator car side top beam 9 for installing these components, counterweight side top beam 12a , 12b and the elevator car main sling fixed base side top beam 23 are located on the plane with the main sling fixed pedestal side elevator car guide rail 13, the elevator car guide rail 14 on the opposite side of the main sling fixed pedestal The main sling fixes the staggered positions of the base side counterweight guide rail 16 and the top beam support column 18 . Therefore, the elevator car guide rail 13 on the side of the main rope fixing base, the elevator car guide rail 14 on the opposite side of the main rope fixing base, the counterweight guide rail 16 on the side of the main rope fixing base, and the top beam support column 18 can be erected. Therefore, like the above embodiment, even in buildings using steel structures, etc., the guide rail bracket can be easily installed on the beams and fastening plates at the top of the elevator passage of the building. Wait, so there is no need to add middle beams etc. below the top beam.

此外，从所有的悬吊负载以及卷扬机4的绳轮的上拉负载与支承这些负载的主吊索固定基座侧电梯轿厢导轨13、主吊索固定基座的相反侧的电梯轿厢导轨14、主吊索固定基座侧平衡重导轨16以及顶部横梁支承柱18之间的位置关系来看，所有的载重的作用位置均位于由连结两根电梯轿厢导轨13、14和主吊索固定基座侧平衡重导轨16以及顶部横梁支承柱18的虚拟直线围成的虚拟四边形中，所以能够减少负载局部地集中在导轨或者顶部横梁支承柱的情况发生，从而不需要增大导轨和顶部横梁支承柱的尺寸，并且能够抑制制造成本的上升。In addition, from all suspended loads and the pull-up load of the sheave of the hoisting machine 4 and the elevator car guide rail 13 on the side of the main rope fixing base supporting these loads, and the elevator car guide rail on the opposite side of the main rope fixing base, 14. From the perspective of the positional relationship between the main sling fixed base side balance weight guide rail 16 and the top beam support column 18, all the loads are located at the position where the two elevator car guide rails 13, 14 and the main sling are connected. In the imaginary quadrilateral surrounded by the virtual straight line of the fixed base side counterweight guide rail 16 and the top beam support column 18, it is possible to reduce the local concentration of the load on the guide rail or the top beam support column, so that there is no need to enlarge the guide rail and the top beam support column. The beam supports the size of the column, and an increase in manufacturing cost can be suppressed.

并且，在连结主吊索固定基座侧电梯轿厢导轨14的背面和主吊索固定基座侧平衡重导轨16的背面的虚拟直线与升降通道侧壁平行时，能够使电梯轿厢侧顶部横梁9的结构变得简单，为此能够降低成本。And, when the imaginary straight line connecting the back side of the elevator car guide rail 14 on the side of the main rope fixing base and the back side of the counterweight guide rail 16 on the side of the main rope fixing base is parallel to the side wall of the hoistway, it is possible to make the top of the elevator car side The structure of the crossbeam 9 becomes simple, and it can reduce cost for this.
