Embodiment 1 FIG.
The first embodiment will be described with reference to FIGS.

  With reference to FIG. 1 and FIG. 2, the state in which the air conditioner 4 is attached to the upper part of the elevator cab 1 will be described, and the feature of the mounting structure of the air conditioner 4 in Embodiment 1 with reference to FIG. Indicates. FIG. 1 is a diagram showing a state in which the air conditioner 4 is attached to the upper part of the car room ceiling 9 as viewed from a direction perpendicular to the hoistway. FIG. 2 is a diagram illustrating a state in which the air conditioner 4 is attached as viewed from the upper part of the hoistway. FIG. 3 is a diagram showing the characteristics of the mounting structure of the first embodiment. As shown in FIG. 3, the air conditioner 4 is capable of rotating around the bolt 12b as a fulcrum for rotation. As a result, the air conditioner 4 can be further lifted by ΔB with respect to the cab ceiling 9 with respect to FIG. 1, and there is an advantage that a work space can be secured as follows.

Although the air conditioner 4 is attached to the mount 61, workability is poor when maintenance is attempted in the attached state shown in FIGS. That is, when the maintenance is performed in a state where the air conditioner 4 is horizontally installed as shown in FIG. 1 without rotating the air conditioner 4 as shown in FIG. 3, for example, the workability is poor in the following points.
(1) In FIG. 1, when the electrical component box 8 is to be maintained, the handrail 7 is positioned at the same height as the electrical component box 8, and, as shown in FIG. And the electrical component box 8 are narrow, so there is no work space for the operator.
(2) In addition, when the air-conditioning equipment 4 is installed horizontally, when trying to remove the blow-out duct 6 from the duct mounting portion 10, or when trying to attach the blow-out duct 6 to the duct mounting portion 10, or When it is going to check the state of the attached outlet duct 6, the work is difficult because the distance B between the car room ceiling 9 and the duct mounting portion 10 is small.
(3) For this reason, when performing the maintenance of (1) and (2) above, if the air conditioner 4 is not rotated as shown in FIG. 3, the air conditioner 4 placed in the horizontal state of FIG. It was necessary to remove the base 61 and move to another place for maintenance work.
(4) On the other hand, according to the mounting structure of the air conditioner 4 of the first embodiment, the air conditioner 4 can be further lifted by ΔB because it can rotate as shown in FIG. For this reason, since the work can be performed in the lifted state, the labor of removing the air conditioner 4 from the mounting base 61 and moving it to another place for maintenance is eliminated.

  Next, details of the mounting structure of the air conditioner 4 will be described with reference to FIGS. 4, 5, and 6. FIG. 4 corresponds to FIG. 1 and specifically shows parts used in the mounting structure, and the suction duct 5 and the blowout duct 6 are shown by hatching. FIG. 5 is a diagram illustrating a front view (FIG. 5A) and a right side view (FIG. 5B) of the air conditioner 4 in a state where the air conditioner 4 is attached. FIG. 5A is a view in which the suction duct 5 and the blowout duct 6 are removed from FIG. FIG. 6 is a diagram illustrating the mounting relationship between the mounting base and the mounting base when the air conditioner 4 is mounted. 6 (a) corresponds to FIG. 5 (a), and FIG. 6 (b) corresponds to FIG. 5 (b).

(1. Outline of mounting structure)
The air conditioner 4 is formed by combining the four mounting bases 11, 21, 31, 41 attached to the corresponding mounting bases 61, 62 with the structure of part A shown by the broken line in FIG. It is attached to the mounting bases 61 and 62. The A-part structure is provided at four locations on both ends of the device-side pedestal mounting portion 51 and on both ends of the device-side pedestal mounting portion 52, all having the same configuration. FIG. 6 shows the connection relationship between components, and does not show the assembly procedure. For example, the mounting base 21 may be attached to the mounting base 61 first.

(2. Installation position of air conditioning equipment)
As shown in FIG. 4, the air conditioner 4 is attached to the upper beam 2 passed to the upper part of the cab 9. In addition, as shown in FIG. 5, the air conditioner 4 includes a duct mounting portion 10 to which the blowout duct 6 is mounted on a lower surface 84 that is a surface facing the cab 9.

(3. Mounting structure on the air conditioner side)
With reference to FIG. 6, the attachment structure by the side of an air-conditioning apparatus is demonstrated. The air conditioner 4 includes a mounting device side pedestal mounting portion 51 and a device side pedestal mounting portion 52 on the lower surface 84. An attachment pedestal 11 (first pedestal) and an attachment pedestal 21 (second pedestal) are attached to the device side pedestal attachment 51. An attachment pedestal 31 (third pedestal) and an attachment pedestal 41 (fourth pedestal) are attached to the device side pedestal attachment 52. The device side pedestal mounting portion 51 and the device side pedestal mounting portion 52 are attached to the lower surface 84 of the air conditioning device 4 by welding or screwing, and become a part of the air conditioning device 4. Although the mounting base 31 does not appear in FIG. 6, in the device side base mounting portion 52, the mounting base 31 is mounted at a position corresponding to the mounting base 11 in the device side base mounting portion 51, and corresponds to the mounting base 21. The mounting base 41 is attached to the position to be used.

(4. Structure of part A)
The structure of the A part will be described with reference to FIG. The mounting pedestal 21 (second pedestal) is attached to the end of the device side pedestal mounting portion 51. The mounting base 21 is attached to an end portion in the longitudinal direction on the lower surface 84 side of the air conditioner 4. The device side pedestal mounting portion 51 has a “U” -shaped cross section. The mounting base 21 is attached by bolts 24b and nuts 24n to the inner surface of the device side base mounting portion 51 on the side where the "U" -shaped protrusion stands up via the vibration isolating rubber 23. That is, a hole through which the bolt shaft of the bolt 24b passes is formed in the device side pedestal mounting portion 51, the vibration isolating rubber 23, and the mounting pedestal 21, and the bolt shaft is connected to the device side pedestal mounting portion 51, the vibration isolating rubber 23, After passing through each hole of the mounting base 21, it is stopped with a nut 24n.

(5. Mounting relationship between mounting base 61 and upper beam 2)
Next, the mounting relationship between the mounting base 61 and the upper beam 2 will be described with reference to FIG. The mounting structure of the mounting base 62 and the upper beam 2 is the same. The upper beam 2 is fixed to the vertical column 3 of the car frame with bolts. The mounting base 61 is fixed to the upper surface of the upper beam 2 with bolts 81b, nuts 81n, bolts 82b, nuts 82n, and the like. The mounting base 61 (first elongated material) is an elongated material having a length substantially the same as the length in the longitudinal direction of the air conditioner 4 (equipment side pedestal mounting portion 51) and having a “U” shape in cross section. The mounting base 62 (second elongated material) is also an elongated material having a cross-sectional “U” shape having substantially the same length as the length in the longitudinal direction of the air conditioner 4 (equipment side pedestal mounting portion 52). The mounting base 62 is juxtaposed to the upper beam 2 at an interval larger than the maximum width of the duct mounting portion 10 in a direction substantially orthogonal to the longitudinal direction of the air conditioning equipment 4 with respect to the mounting base 61. That is, although the mounting base 61 and the mounting base 62 are arranged at positions sandwiching the duct mounting portion 10 of the air conditioning equipment 4, the distance between the mounting base 61 and the mounting base 62 is larger than the maximum width of the duct mounting portion 10. Therefore, the mounting base 61 and the mounting base 62 do not interfere with the duct mounting portion 10. Further, the chamfering process (curvature R) is performed on the portion B surrounded by the broken lines at both ends of the mounting base 61. This is to prevent interference between the mounting base 11 and the mounting base 61 on the rotation support side when the air conditioner 4 rotates as shown in FIG. In FIG. 6, chamfering is performed on both ends of the mounting base 61. The same applies to the mounting base 62.

(6. Mounting relationship between mounting base and mounting base)
The mounting relationship between the mounting base and the mounting base will be described with reference to FIG. The A part will be described. As described above, the other three places have the same attachment relationship as the A part. The mounting base 21 is attached to the mounting base 61 with bolts 22b and nuts 22n. As shown in FIG. 6, the mounting base 21 and the mounting base 61 have holes through which the bolt shafts of the bolts 22b pass. As shown in FIG. 5, the mounting base 21 and the mounting base 61 are attached such that the protruding sides of the “U” shape are combined with each other. Since the inner width of the “U” cross section of the mounting base 21 is slightly wider than the outer width of the “U” cross section of the mounting base 61, the mounting base 21 can be combined with the mounting base 61. The nut 22n is tightened through the bolt shaft of the bolt 22b with the through holes of the mounting base 21 and the mounting base 61 overlapping. Alternatively, the nut 22n may be welded to the mounting base 61. In FIG. 6, only one of the bolts 22b is shown for explanation, but actually, as shown in FIG. 5, it is fixed by two sets of bolts 22b and nuts 22n. In this case, the axis of the bolt shaft of the bolt 22 b is a direction substantially perpendicular to the longitudinal direction of the mounting base 61. That is, the bolt shafts of the four bolts 22b for fixing the mounting base 21 to the mounting base 61 and the two bolts 42b for fixing the mounting base 41 to the mounting base 62 are substantially the same. Similarly, the four bolt shafts of the two bolts 12b for fixing the mounting base 11 to the mounting base 61 and the two bolts 32b for fixing the mounting base 31 to the mounting base 62 have substantially the same bolt shaft. This is because, as shown in FIG. 3, in order for the air conditioner 4 to rotate using the bolts 12b and 32b as fulcrums, the bolt shafts need to be substantially the same. Note that the bolt shafts of the mounting base 21 side, the mounting base 41 side and the bolts 22b and 42b that are not the fulcrum of rotation in FIG. 3 are not required. In FIG. 3, it is also possible to rotate the bolt 22b and the bolt 42b as fulcrums.

(7. Procedure to rotate)
A procedure for changing the normal installation state of the air conditioner 4 shown in FIG. 5 (during normal elevator operation) to the state shown in FIG. 3 (during maintenance) when the air conditioner 4 is rotated will be described.
(1) The operator removes all the bolts 22b (second bolts) of the mounting base 21 and the bolts 42b (fourth bolts) of the mounting base 41 (four in total in this example).
(2) Further, the operator loosens all the bolts 12b (first bolts) of the mounting base 11 and the bolts 32b (third bolts) of the mounting base 31 (four in total in this example).
(3) As a result, the air conditioner 4 can rotate as shown in FIG. 3 using the two bolts 12b (first bolt) and the two bolts 32b (third bolt) as fulcrums for rotation. . The operator can rotate the air conditioner 4 to the state shown in FIG.

(8. Support members)
FIG. 7 is a diagram showing a case where a support member 71 (a connecting member) that fastens the mounting base 21 and the end of the mounting base 61 is used in the state of FIG. 3. The support member 71 may be fixed to the holes of the mounting base 21 and the mounting base 61 provided exclusively by pins 72 and 73 (in the case of FIG. 7), or one end of the mounting base 71 is passed through the bolt 22b. It may be attached to the hole of the pedestal 21 with a pin 73, and the other end may be attached to the hole of the mounting base 61 through which the bolt 22b passes with the pin 72. At this time, the equipment side pedestal mounting portion 51, the mounting base 61, and the support member 71 constitute three links, so that the support member 71 can support the rotation of the equipment side pedestal mounting portion 51 (air conditioner 4). Note that one end of the support member 71 is attached to the mounting base 21. However, as long as the three links are configured, the supporting member 71 may be attached to the equipment side base attaching part 51 or may be attached to the air conditioner 4 itself. Absent. In addition, you may attach to the mounting base 61 or the mounting base 21 so that the one end of the supporting member 71 can be moved freely. Thereby, the lifted state can be held immediately. Further, a support member may be attached to the mounting base 62 as well as the mounting base 61.

  With the mounting structure of the air conditioner 4 according to the first embodiment described above, if the bolt of one mounting base is removed, the fixing bolt of the other mounting base can be used as a fulcrum to rotate and lift the entire air conditioner. For this reason, work efficiency, such as attachment and replacement of a duct, can be improved. Moreover, since the visibility of the attachment part of a duct improves by rotating and lifting with an air conditioner, the burden of installation and a maintenance work is reduced. Moreover, since the cross section of the mounting base 61 and the mounting base 62 has a “U” shape, the rigidity can be increased and the mounting position of the air conditioner 4 can be lowered as compared with the case of combining L-shaped steel materials. In addition, the maintainability can be improved.

  In the first embodiment described above, the mounting base for attaching the air conditioner 4 to the upper beam 2 of the car frame as shown in FIG. 1 has a U-shaped rail shape with chamfered corners as shown in FIG. The mounting structure of the air conditioner characterized in that the bolt fastening positions of the mounting base and the mounting base (rail) of the air conditioning equipment body are close to both ends of the mounting base (rail) has been described. With this “air conditioning equipment mounting structure”, when the air duct or suction duct connecting the air conditioning equipment and the car room comes out from the lower part of the air conditioning equipment body, the above mounting structure is adopted, as shown in FIG. When the duct is attached or detached, the air-conditioning device main body can be lifted with the fixing bolt of the mounting base on the opposite mounting base as a fulcrum by removing the bolt on the mounting base to which the air-conditioning device main body on one side is attached. For this reason, visibility and workability are improved in duct installation / replacement work.

In the above first embodiment, as shown in FIG. 7, the mounting structure of the air conditioner including the support member that fastens the mounting base and the mounting base has been described. Air-conditioning equipment is usually heavy, and it is difficult for one worker in terms of workability and safety. Therefore, by providing the support member 71, it is possible to maintain the lifted state of the air conditioner, and work safety and workability are improved.
