Description

【Technical Field】 【0001】 The present invention relates to a component mounting bracket and an elevator. 【Background Art】 【0002】 Conventionally, an elevator has a car and guide rails that support the car so that it can move up and down. Various components such as sensors for detecting the distance from the guide rails, speakers, and air conditioning equipment are attached to the car. 【0003】 As an elevator with components installed in the car, for example, there is one described in Patent Document 1. Patent Document 1 describes a speed detection device attached to a car for detecting the speed of the car inside the hoistway where the car moves up and down. And Patent Document 1 describes that it includes a detection unit for image-detecting the surface state of a pair of guide rails laid opposite each other in the hoistway along the movement path of the car, and an arithmetic unit for calculating the speed of the car from the image difference of the guide rail surface detected by the detection unit. 【0004】 Also, the car is supported by the guide rails by a guide device. This guide device includes a roller-type guide device composed of a plurality of guide rollers and a guide shoe-type guide device having a guide shoe that slides on the guide rail. And in the guide shoe-type guide device, an oil tank for supplying oil to the guide shoe is arranged above the car. 【Prior Art Documents】 【Patent Documents】 【0005】 【Patent Document 1】 Japanese Unexamined Patent Application Publication No. 2020-7085 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0006】 However, with guide shoe type guide devices, refueling the oil tank was necessary during maintenance and inspection. Therefore, when installing various components on the elevator car, guide shoe type guide devices had to be installed with the top of the oil tank open to facilitate maintenance and inspection. In contrast, with roller type guide devices, there is no need to consider the open state of the top of the guide device when installing various components on the elevator car. Therefore, conventionally, when installing various components on top of the elevator car, different mounting structures were used depending on the specifications of the guide device, making the installation work of various components very complicated. 【0007】 Considering the above problems, the object of the present invention is to provide a component mounting bracket and elevator that can install components on the top of the elevator car without being affected by the specifications of the guide device. [Means for solving the problem] 【0008】 To solve the above problems and achieve the objective, a component mounting bracket reflecting one aspect of the present invention is used to mount a component to the upper part of a vehicle car that moves up and down along a guide rail via a guide device. The component mounting bracket comprises a support portion installed on the upper part of the vehicle car in the vertical direction so as to be able to approach and move away from the guide rail, and a mounting surface portion connected to the support portion on which the component is placed. 【0009】 Furthermore, the elevator comprises a car that moves up and down within a hoistway provided in a building structure, guide rails erected in the direction in which the car moves up and down within the hoistway, and a guide device provided on the car that guides the car along the guide rails. The elevator also comprises a component positioned at the top of the car and a component mounting bracket for attaching the component to the car. The component mounting bracket is a component mounting bracket having the configuration described above. [Effects of the Invention] 【0010】 With the component mounting bracket and elevator configured as described above, the components can be installed on top of the elevator car without being affected by the specifications of the guide device. Furthermore, issues, configurations, and effects other than those mentioned above will be clarified by the following description of the embodiments.

[Modes for carrying out the invention] 【0012】 Hereinafter, embodiments of a component mounting bracket and an elevator will be described with reference to FIGS. 1 to 11. In each figure, common members are denoted by the same reference numerals. 【0013】 1. First Embodiment Example 1-1. Configuration of Elevator First, the configuration of the elevator according to the first embodiment example (hereinafter referred to as "this example") will be described with reference to FIG. 1. FIG. 1 is a schematic configuration diagram showing the car of the elevator in this example. 【0014】 As shown in FIG. 1, the elevator has a car 1 that moves up and down in a hoistway provided in a building structure, a guide rail 4 that supports the car 1 movably, and a main rope (not shown) and the like connected to the car 1. The guide rail 4 is disposed on both sides in the width direction orthogonal to the vertical direction in which the car 1 moves up and down, and stands in the hoistway along the up and down direction of the car 1. Further, the guide rail 4 is a general T-shaped guide rail that is integrated so as to have a T-shaped cross section. 【0015】 The elevator also has a hoisting machine (not shown) around which the main rope is wound. By driving the hoisting machine, the car 1 moves up and down in the hoistway together with the main rope. 【0016】 The car 2 has a car compartment 2 for people and goods to enter and exit. An opening is provided in the front part of the car compartment 2, and a door 3 is installed in this opening so as to be openable and closable. The car compartment 2 is disposed on both sides in the width direction, and has side faces 2b facing the guide rail 4 and a ceiling 2a disposed at the upper part in the vertical direction. 【0017】 Furthermore, the elevator car 2 has a frame that supports the car compartment 2. The frame has a pair of vertical frames 6, an upper frame 7, and a lower frame. The upper frame 7 is positioned above the ceiling 2a of the car compartment 2 in the vertical direction. The upper frame 7 extends along the width direction of the elevator car 2. That is, the longitudinal direction of the upper frame 7 is positioned parallel to the width direction of the elevator car 2. The vertical frames 6 are connected to both ends of the longitudinal direction of the upper frame 7. 【0018】 The vertical frame 6 is positioned between the side portion 2b of the elevator car 2 and the guide rail 4. The vertical frame 6 extends in the vertical direction. Guide devices are provided on the upper frame 7 and the vertical frame 6 to support the elevator car 2 so that it can move along the guide rail 4. Furthermore, the elevator car 2 is equipped with various devices such as a sensor 40 (see Figure 4, etc.) for measuring the distance to the guide rail 4, a speaker, and air conditioning equipment. 【0019】 1-2. Guide device Next, an example of a guide device will be described with reference to Figures 2 and 3. Figure 2 is a perspective view showing a roller-type guide device, and Figure 3 is a perspective view showing a guide shoe-type guide device. 【0020】 The roller-type guide device 10 shown in Figure 2 is positioned on the upper surface of the upper frame 7. The guide device 10 is positioned at both ends in the longitudinal direction of the upper frame 7. Furthermore, the guide device 10 is positioned between the connecting brackets 21 that connect the upper frame 7 and the vertical frame 6. The guide device 10 has a plurality of guide rollers 11 that contact the guide rail 4 and guide the elevator car 1 so that it can move. 【0021】 The guide shoe type guide device 15 shown in Figure 3 is arranged on the upper frame 7 and the vertical frame 6. The guide device 15 has a guide shoe 16 that slides on the guide rail 4 and an oil tank 17 that supplies oil to the guide shoe 16. The guide shoe 16 is arranged on one side facing the guide rail 4 at the upper end of the vertical frame 6. The oil tank 17, similar to the roller type guide device 10, is arranged at both ends in the longitudinal direction of the upper frame 7, between the connecting brackets 21 that connect the upper frame 7 and the vertical frame 6. 【0022】 1-3. Part mounting bracket Next, referring to Figures 4 to 7, the configuration of the component mounting bracket for attaching various devices such as the sensor 40 to the elevator car 1 will be described. Figures 4 and 5 are perspective views showing the component mounting bracket of this example applied to a roller-type guide device. 【0023】 As shown in Figures 4 and 5, the component mounting bracket 22 is positioned on a connecting bracket 21 provided at the corner of the upper frame 7 and the vertical frame 6. The component mounting bracket 22 has a pair of support parts 23 and a mounting surface 24. The pair of support parts 23 are positioned opposite the connecting bracket 21. The support parts 23 are movably fixed to the connecting bracket 21 via fixing bolts 25. 【0024】 Furthermore, the support portion 23 has multiple guide grooves 23a formed therein. The guide grooves 23a are elongated holes that open along the width direction of the elevator car 1, that is, the direction of approaching and moving away from the guide rail 4. These guide grooves 23a extend along the direction of movement of the support portion 23. The multiple guide grooves 23a are formed parallel to each other with spacing in the vertical direction. Fixing bolts 25 are inserted into these guide grooves 23a. The fixing bolts 25 are then fixed to the connecting bracket 21. 【0025】 In this example, we have described an example in which multiple guide grooves 23a are provided (two in this example), but this is not the only option, and the number of guide grooves 23a may be just one. In order to move the component mounting bracket 22 horizontally without any wobbling, it is preferable to provide multiple guide grooves 23a. 【0026】 The upper end of the support portion 23 is positioned above the guide device 10 located on the upper frame 7. A mounting surface portion 24 is continuously provided on the upper end of the support portion 23. The mounting surface portion 24 connects the pair of support portions 23. The mounting surface portion 24 is positioned above the guide device 10 located on the upper frame 7. Therefore, under normal circumstances, the mounting surface portion 24 covers the top of the guide device 10. A sensor 40 is positioned on this mounting surface portion 24. 【0027】 The sensor 40 positioned on the mounting surface 24 faces the guide rail 4. The sensor 40 is, for example, a distance sensor that measures the distance between the guide rail 4 and the elevator car 1. However, the sensor 40 is not limited to a distance sensor; a position detection sensor that detects the position of the elevator car 1 and various other types of sensors can also be used. 【0028】 As shown in Figure 5, when inspecting the guide device 10 and sensor 40 during maintenance, first loosen the fixing bolt 25 and move the support part 23 along the guide groove 23a. This allows the sensor 40 to be moved away from the guide rail 4. By increasing the distance between the sensor 40 and the guide rail 4 from the normal distance, the sensor 40 can detect that the current state is a maintenance inspection state. This makes maintenance inspection work safer. 【0029】 Furthermore, the mounting surface 24 of the component mounting bracket 22 and the sensor 40 are detached from above the guide device 10. As a result, the area above the guide device 10 in the vertical direction is opened up. This makes it easier to inspect the guide device 10. 【0030】 Once the maintenance work is complete, the support part 23 is moved toward the guide rail 4. Then, when the component mounting bracket 22 moves to the predetermined position, the fixing bolt 25 is tightened to secure the support part 23 to the connecting bracket 21. At this point, by using the detection signal from the sensor 40, it is easy to determine that the maintenance work is complete and that the sensor 40 and component mounting bracket 22 are in their predetermined positions. As a result, it is possible to detect if the component mounting bracket 22 or sensor 40 have been forgotten to be returned when the maintenance work is completed. 【0031】 Figures 6 and 7 are perspective views showing an example of applying the component mounting bracket 22 having the above-described configuration to a guide shoe type guide device 15. As shown in Figure 6, under normal conditions, the mounting surface 24 of the component mounting bracket 22 is positioned above the oil tank 17 of the guide device 15 in the vertical direction, covering the top of the oil tank 17. Then, as shown in Figure 7, during maintenance and inspection, similar to the roller-type guide device 10, the support portion 23 moves along the guide groove 23a, and the component mounting bracket 22 and sensor 40 move away from the guide rail 4. 【0032】 As the support portion 23 moves, the mounting surface portion 24 of the component mounting bracket 22 and the sensor 40 are removed from above the oil tank 17 of the guide device 15. As a result, the area above the oil tank 17 in the vertical direction is opened up. This makes it easier to perform inspection work on the guide device 15 and refueling work on the oil tank 17, thereby reducing working time. 【0033】 As described above, the component mounting bracket 22 in this example can be applied to different types of guide devices, such as the roller-type guide device 10 and the guide shoe-type guide device 15. In other words, the device can be installed on top of the elevator car without being affected by the specifications of the guide device. As a result, the component mounting bracket 22 can be standardized, eliminating the need to change the structure of the component mounting bracket according to different types of guide devices, and making the installation of the sensor 40 easier. 【0034】 Furthermore, with the component mounting bracket 22 in this example, there is no need to remove the component during maintenance and inspection, so the wiring of the sensor 40 is not affected by the work. 【0035】 Furthermore, although the above-described embodiment example shows the mounting surface 24 of the component mounting bracket 22 and the sensor 40 positioned above the guide devices 10 and 15, the invention is not limited to this. For example, the mounting surface 24 of the component mounting bracket 22 and the sensor 40 may be positioned below the guide devices 10 and 15 in the vertical direction. 【0036】 2. Second Embodiment Example Next, a component mounting bracket according to a second embodiment will be described with reference to Figures 8 to 11. Figures 8 to 11 show a component mounting bracket according to a second embodiment. Figures 8 and 9 are perspective views of the component mounting bracket according to the second embodiment applied to a roller-type guide device 10. Figures 10 and 11 are perspective views of the component mounting bracket according to the second embodiment applied to a roller-type guide device 15. 【0037】 The difference between the component mounting bracket 32 ​​in this second embodiment and the component mounting bracket in the first embodiment is the configuration of the direction of movement. Therefore, here, the same reference numerals are used for parts that are common to the component mounting bracket in the first embodiment, and redundant explanations are omitted. 【0038】 As shown in Figures 8 and 9, the component mounting bracket 32 ​​has a pair of support parts 33 and a mounting surface 34. The pair of support parts 33 are positioned opposite the connecting bracket 21. The support parts 33 are supported on the connecting bracket 21 so as to be movable (rotatable) via a pivot shaft 36. 【0039】 The pivot shaft 36 is positioned at the lower end of the support portion 33 in the vertical direction, on the end that is separated from the guide rail 4. A guide groove 33a is also formed in the support portion 33. The guide groove 33a is an arc-shaped elongated hole centered on the pivot shaft 36. A fixing bolt 35 is inserted into this guide groove 33a. 【0040】 A mounting surface 34 on which the sensor 40 is placed is positioned at the upper end of the support portion 33. Under normal circumstances, the mounting surface 34 covers the upper part of the guide device 10. As shown in Figure 9, an opening is formed on the lower surface of the mounting surface 34 opposite to the upper surface on which the sensor 40 is placed, exposing the connection portion 40a of the sensor 40. Wiring that electrically connects to the sensor 40 is connected to this connection portion 40a. The wiring is then inserted through the opening formed in the mounting surface 34. By providing the first fixing point of the wiring connected to the sensor 40 on the component mounting bracket 32 ​​side in this way, the wiring of the sensor 40 is not affected even when the component mounting bracket 32 ​​is moved. As a result, it is possible to prevent the wiring from coming off the sensor 40 during maintenance and inspection. 【0041】 When inspecting the guide device 15 and sensor 40 during maintenance, first loosen the fixing bolt 35. Then, as shown in Figure 9, rotate the support part 33 around the pivot axis 36 at an angle of approximately 90 degrees. This causes the mounting surface part 34 to be parallel to the vertical direction. As a result, the support part 33 and the mounting surface part 34 are separated from the guide rail 4. In addition, the mounting surface part 34 of the component mounting bracket 32 ​​and the sensor 40 are removed from above the guide device 10. As a result, the area above the guide device 10 in the vertical direction is opened up. This makes it easier to inspect the guide device 10. 【0042】 Furthermore, as the component mounting bracket 32 ​​rotates, the sensor 40 faces a different direction from the direction opposite to the guide rail 4. In other words, when the guide rail 4 moves out of the detection direction of the sensor 40, the sensor 40 can detect that the current state is a maintenance inspection state. This makes maintenance inspection work safer. 【0043】 Once the maintenance work is complete, the support unit 33 is rotated around the pivot axis 36. This causes the sensor 40 to face the guide rail 4, and the guide rail 4 to enter the detection range of the sensor 40. Therefore, by using the detection signal from the sensor 40, it is easy to determine that the maintenance work is complete and that the sensor 40 and the component mounting bracket 32 ​​have been returned to their predetermined positions. 【0044】 Figures 10 and 11 are perspective views showing an example of applying the component mounting bracket 32 ​​having the above-described configuration to a guide shoe type guide device 15. As shown in Figure 10, under normal conditions, the mounting surface 34 of the component mounting bracket 32 ​​is positioned above the oil tank 17 of the guide device 15 in the vertical direction, covering the top of the oil tank 17. Then, as shown in Figure 11, during maintenance and inspection, similar to the roller-type guide device 10, the support portion 33 rotates around the pivot axis 36, and the component mounting bracket 32 ​​and sensor 40 move away from the guide rail 4. 【0045】 As the support portion 33 rotates, the mounting surface portion 34 of the component mounting bracket 32 ​​and the sensor 40 are removed from above the oil tank 17 of the guide device 15. As a result, the area above the oil tank 17 in the vertical direction is opened up. This makes it easier to perform inspection work on the guide device 15 and refuel the oil tank 17. 【0046】 In this second embodiment, the same component mounting bracket 32 ​​can be used for different types of guide devices, similar to the component mounting bracket 22 in the first embodiment. As a result, the component mounting bracket 32 ​​can be standardized, eliminating the need to change the structure of the component mounting bracket according to different types of guide devices, and making the installation of the sensor 40 easier. 【0047】 The other components are the same as those of the component mounting bracket 22 in the first embodiment described above, so their description will be omitted. The component mounting bracket 32 ​​in this second embodiment can also be made to have the same functions and effects as the component mounting bracket 22 in the first embodiment described above. 【0048】 Furthermore, according to the component mounting bracket 32 ​​of the second embodiment, after maintenance work is completed, the support portion 33 can be rotated to a position where its rotation stops, returning it to its normal initial position. As a result, positioning work on the sensor 40 relative to the guide rail 4 can be easily performed. Moreover, when the mounting surface portion 34 is tilted with respect to the horizontal direction, the sensor 40 does not face the guide rail 4. Therefore, with a configuration in which the support portion 33 and the mounting surface portion 34 rotate, as in the component mounting bracket 32 ​​of the second embodiment, it is easy to determine from the detection signal of the sensor 40 whether maintenance work has been completed and the sensor 40 has been returned to its normal position. 【0049】 Furthermore, the invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the gist of the invention as described in the claims. 【0050】 Furthermore, in the above-described embodiment, a sensor 40 for measuring the distance to the guide rail 4 was used as an example of a component to be installed in the elevator car 1, but the invention is not limited to this. For example, speakers, air conditioning equipment, and various other components may be attached to the elevator car 1 using the component mounting bracket described above. By using the sensor 40 as a component, it is possible to detect whether the current state is normal or during maintenance and inspection. 【0051】 The aforementioned component mounting brackets can be applied not only to 1:1 roping and 2:1 roping elevators that use a hoisting machine to raise and lower the elevator car, but also to hydraulic elevators and various other types of elevators. 【0052】 Furthermore, while the above-described embodiment illustrates the installation of a component mounting bracket in a new elevator, it is not limited to this. For example, when refurbishing an existing elevator, the component mounting bracket described above may be used to install a new component. 【0053】 Furthermore, this technology can also be applied to multi-car elevators, where multiple elevator cars move up and down within a single hoistway. 【0054】 In this specification, although terms such as "parallel" and "orthogonal" are used, these do not mean only strictly "parallel" and "orthogonal," but may also refer to states that are "approximately parallel" or "approximately orthogonal," which include "parallel" and "orthogonal" and are within a range in which they can perform their functions.
