Description

[Technical field]

[0001] The present invention relates to an elevator device. [Background technology]

[0002] Patent Document 1 describes an elevator equipped with a fixing part that fixes the position of a hoist having a sheave around which a rope is wound (see paragraphs 0013 and 0017). The fixing part includes a lower fixing member having a connection part directly connected to one counterweight rail and the other counterweight rail, respectively, and an upper fixing member having a connection part indirectly connected to one car rail and the other counterweight rail, respectively (see paragraph 0018). The lower fixing member and the hoist are connected by a connecting member with a vibration-proof member sandwiched between them in the vertical direction (see paragraph 0019). The upper fixing member and the upper part of the hoist are connected by a connecting member with a vibration-proof member sandwiched between them in the direction of the rotation axis of the sheave (see paragraph 0020).

[0003] [Patent Document 1] JP 2019-137511 A Summary of the Invention [Problem to be solved by the invention]

[0004] When the rope is wound around the sheave, the hanging load of the rope, the car, and the counterweight (balance weight) acts on the hoist, causing the sheave to tilt in the direction of the rotation axis. In a structure in which the upper fixed member and the hoist are connected in the direction of the rotation axis of the sheave with a vibration-proof member sandwiched between them as in Patent Document 1, when an elastic body is used as the vibration-proof member, the amount of tilt of the hoist will change if a hanging load is applied after the elastic body is attached in a non-suspended state. In order to keep the amount of tilt of the hoist within a reference value (within an allowable range), for example, a method of adjusting the amount of tilt of the hoist by inserting and removing a tilt adjustment plate (thin plate: liner) between the upper fixed member and the hoist is considered. Conventionally, it is difficult to insert and remove the tilt adjustment plate while the hanging load is applied to the hoist, and in order to insert and remove the tilt adjustment plate, it was necessary to remove the hanging load once. For this reason, it took a long time to adjust the amount of tilt of the hoist.

[0005] An object of the present invention is to provide an elevator apparatus capable of adjusting the amount of inclination of a hoisting machine without removing a suspended load. [Means for solving the problem]

[0006] In order to solve the above problems, the elevator device of the present invention comprises: An elevator apparatus including a lifting body that moves up and down a hoistway, a guide rail that guides the lifting body as it moves up and down, a main rope connected to the lifting body, a hoisting machine having a sheave around which the main rope is wound, and a hoisting machine support section that supports the hoisting machine, The hoist support portion is A lower support portion disposed below the hoist; An upper support portion disposed at an upper portion of the hoisting machine in a position facing a sheave side surface; a first adjustment unit and a second adjustment unit that adjust a gap between the upper support portion and a surface of the sheave side in a direction of a rotation axis of the sheave; having The second adjustment portion makes it possible to adjust the interval with the main rope wound around the sheave. Effect of the Invention

[0007] According to the present invention, it is possible to provide an elevator device that can adjust the amount of tilt of a hoisting machine without unloading a suspended load.

[0008] Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0011] The configuration of the elevator device 100 will be described with reference to Figs. Fig. 1 is a vertical cross-sectional view showing the configuration of an elevator system 100 according to an embodiment of the present invention. In Fig. 1, the size of the hoistway HW and the position and orientation of each device arranged in the hoistway HW are depicted in a form different from the actual one in order to explain the configuration of the elevator system 100. Fig. 1 also shows a state in which the car 104 is stopped at a landing 112 on the top floor.

[0012] The X-axis, Y-axis, and Z-axis directions are defined as shown in Fig. 1. The X-axis direction is horizontal and coincides with the width direction of the car 104. The Y-axis direction is horizontal and coincides with the depth direction of the car 104. The Z-axis direction is vertical (up and down) and coincides with the direction in which the car 104 rises and falls.

[0013] The elevator device 100 comprises a car 104 and a counterweight 105 that rise and fall within a hoistway HW, a hoist 102 around which a main rope 107 connected to the car 104 and the counterweight 105 is wound, a guide rail 109 that is erected in the hoistway HW and guides the rise and fall of the car 104 and the counterweight 105, a control panel 101 that controls the elevator device 100, and a governor 111 (see Figure 2) for detecting the rising and falling speed of the car 104.

[0014] The car 104 and counterweight 105 are provided inside a hoistway HW provided in a building, and are suspended in a bucket-like manner by a main rope 107. One end of the main rope 107 is supported near the ceiling of the hoistway HW, hung around a pulley 104b provided on the underside of the car 104, and wound around a sheave 102b of the hoisting machine 102. The other end of the main rope 107 wound around the sheave 102b of the hoisting machine 102 is passed through a pulley 105a of the counterweight 105 and supported near the ceiling of the hoistway HW (the hoisting machine support part 120).

[0015] The car 104 is electrically connected to the control panel 101 by a tail cord (not shown), receives power via the tail cord, and exchanges control signals and various other signals with the control panel 101. A buffer 106 is disposed on the bottom of the elevator shaft HW below the car 104 and the counterweight 105. In Fig. 1, the buffer 106 for the counterweight 105 is illustrated, but the buffer for the car 104 is not illustrated.

[0016] The hoisting machine 102 is supported by a hoisting machine support part 120 and is disposed at the top of the hoistway HW. The control panel 101 is disposed at the top of the hoistway HW and is disposed in the vicinity of the hoisting machine 102. The support part 120 is illustrated in a simplified manner in Fig. 1, and the configuration of the hoisting machine support part 120 will be described in detail later.

[0017] The car 104 and the counterweight 105 are guided in the vertical direction (ascending and descending direction) by a guide rail 109 erected in the vertical direction (height direction) along the inner wall (side wall) HW1 of the hoistway. The guide rail 109 is supported by a support base (guide rail support base) 103 and fixed to the inner wall HW1 of the hoistway HW by a rail bracket (not shown).

[0018] That is, in the elevator device 100 of this embodiment, an elevator body consisting of a car 104 connected to a main rope 107 and a counterweight 105 is guided by a guide rail 109 and ascends and descends in a hoistway HW.

[0019] The governor 111 is a device that detects the ascending and descending speed of the car 104, and has a main body (governor sheave) 111a, an upper diverting pulley 111b arranged above the main body 111a, a lower diverting pulley 111c arranged below the main body 111a, and a governor rope 111e wound around the main body 111a, the upper diverting pulley 111b, and the lower diverting pulley 111c.

[0020] Fig. 2 is a cross-sectional view parallel to the horizontal direction showing the configuration of an elevator system 100 according to an embodiment of the present invention. Note that Fig. 2 illustrates the state of the elevator shaft HW as seen from above the car 104, and depicts the car top 104c of the car 104.

[0021] A car door 104a is provided on the side of the car 104 facing the elevator hall 112. An entrance door 112a is provided on the elevator hall 112 side at a position opposite the car door 104a. A space is provided between the hoistway wall HW1 and the other sides of the car 104 except for the side on which the car door 104a is provided, in which equipment (hoistway interior equipment) such as the hoistway machine 102, the governor 111, and the control panel 101 are disposed.

[0022] To enable such an arrangement, the hoist 102 is configured as a thin hoist in which the dimension in the direction of the rotation axis (x-axis) of the sheave 102b is smaller than the dimension in the horizontal direction and in the direction perpendicular to the rotation axis (y-axis). In this embodiment, the hoist 102 and the governor 111 are arranged in the space on the left side of the car 104 when viewed from the elevator hall 112 side. The hoist 102 is fixed to the hoistway wall HW1 by the hoistway support part 120 (see FIG. 1). The hoistway support part 120 is fixed to the car guide rail 109A and the counterweight guide rail 109B, and the hoist 102 is fixed to the hoistway wall HW1 via the guide rail 109.

[0023] The control panel 101 is disposed in a space formed on the right side of the car 104 when viewed from the elevator hall 112 side. The control panel 101 is fixed to the hoistway wall HW1 by a control panel bracket (not shown). In this case, the control panel bracket is fixed to the car guide rail 109A, and the control panel 101 is fixed to the hoistway wall HW1 via the car guide rail 109A.

[0024] The elevator device 100 of this embodiment is of a traction type, in which the hoist 102 frictionally drives the main rope 107 to raise and lower the car 104 up and down along the car guide rails 109A, and raise and lower the counterweight 105 up and down along the counterweight guide rails 109B. That is, the guide rails 109 described in FIG. 1 include a pair of car guide rails 109A that guide the car 104, and a pair of counterweight guide rails 109B that guide the counterweight 105.

[0025] The car guide rail 109A includes a car guide rail 109Aa arranged on one side of the car 104 in the width direction (x-axis direction) of the car 104, and a car guide rail 109Ab arranged on the other side of the car 104 in the width direction (x-axis direction) of the car 104. The counterweight guide rail 109B includes a counterweight guide rail 109Ba arranged on one side of the counterweight 105 in the depth direction (y-axis direction) of the car 104, and a counterweight guide rail 109Bb arranged on the other side of the counterweight 105 in the depth direction (Y-axis direction) of the car 104.

[0026] One car guide rail 109Aa and one counterweight guide rail 109Ba are fixed to the hoistway wall HW1 by a shared rail bracket 108C shared by the car guide rail 109Aa and the counterweight guide rail 109Ba. The other car guide rail 109Ab is fixed to the hoistway wall HW1 by a car rail bracket 108A. The other counterweight guide rail 109Bb is fixed to the hoistway wall HW1 by a counterweight rail bracket 108B.

[0027] A pair of counterweight guide rails 109B and one car guide rail 109Aa are disposed in a space between one side surface 104d1 of the car 104 and the elevator shaft wall HW1. In this embodiment, the side surface 104d1 of the car 104 is the left side surface (left side surface) when facing the car 104 from the elevator hall 112. The common rail bracket 108C is fixed to the elevator shaft wall HW1 facing the left side surface 104d1 of the car 104 as viewed from the elevator hall 112. The counterweight rail bracket 108B is fixed to the elevator shaft wall HW1 facing the back surface 104d2 of the car 104. The car rail bracket 108A is fixed to the elevator shaft wall HW1 facing the right side surface (right side surface) 104d3 of the car 104 as viewed from the elevator hall 112. The arrangement of the pair of counterweight guide rails 109B and the pair of car guide rails 109Aa is not limited to the arrangement described above.

[0028] Hereinafter, when there is no need to distinguish between the car guide rail 109A and the counterweight guide rail 109B for the car and the counterweight, they will be simply referred to as guide rails 109 in the description.

[0029] As described above, the elevator device 100 of this embodiment includes the lifting bodies 104, 105 that rise and fall in the elevator shaft HW, a guide rail 109 that guides the rise and fall of the lifting bodies 104, 105, a main rope 107 connected to the lifting bodies 104, 105, a hoisting machine 102 having a sheave 102b around which the main rope 107 is wound, and a hoisting machine support part 120 that supports the hoisting machine 102.

[0030] The configuration of the support portion (hoisting machine support portion) 120 of the hoisting machine 102 will be described with reference to Figs. 3 to 5. Fig. 3 is a plan view showing the configuration of the hoisting machine support part 120 according to one embodiment of the present invention and its arrangement in the hoistway HW. Fig. 4 is a projection view of the hoisting machine support part 120 shown in Fig. 3 in the view of an arrow IV. Fig. 5 is a cross-sectional view of the hoisting machine support part 120 shown in Fig. 3 in the view of an arrow VV.

[0031] As shown in Figs. 3 to 5, the hoist support section 120 includes a lower support section 121 disposed below the hoist 102, and an upper support section 122 disposed at an upper portion of the hoist 102 in a position facing the front surface (the surface on the sheave 102b side). The hoist 102 is placed on the lower support section 121, and supports the weight of the hoist 102. The upper support section 122 is provided to support the upper portion of the main body section 102a of the hoist 102 from the car 104 side, and suppresses the main body section 102a from falling (tilting) toward the sheave 102b side. In the following description, the surface of the main body section 102a on which the sheave 102b is provided is referred to as the front surface, and the opposite surface is referred to as the back surface.

[0032] As shown in FIG. 4, the lower support 121 is installed between a pair of counterweight guide rails 109B and fixed to the counterweight guide rails 109B. The lower support 121 is connected to the counterweight guide rails 109B by a connecting member 126. The lower support 121 and the connecting member 126 are formed using shaped steel, castings, or the like. The hoist 102 is placed on a stand 127 fixed to the lower support 121 via an elastic body (elastic member) 124, and is fixed to the counterweight guide rail 109B via the elastic body 124, the stand 127, the lower support 121, and the connecting member 126. In this case, the hoist 102 is connected to the stand 127 by a connecting member 129 with the elastic body (elastic member) 124 sandwiched therebetween. The connecting member 129 may be, for example, a bolt and a nut, but is not limited to this.

[0033] The elastic body 124 functions as a vibration-proofing member that suppresses the transmission of vibration. The vibration-proofing member is, for example, a vibration-proof rubber. Therefore, the hoist 102 can be displaced relative to the counterweight guide rail 109B within the deformable range of the elastic body 124, and the fixation of the hoist 102 to the counterweight guide rail 109B does not mean a strict fixation that does not allow even a slight displacement.

[0034] In this embodiment, as shown in Figures 3 to 5, one end 107a of the main rope 107 is fixed to a lower support part 121. On the other hand, the other end 107b of the main rope 107 is fixed to a main rope fixing member 107c fixed to a car guide rail 109Ab as shown in Figure 3. The lower support part 121 also serves as a main rope fixing member for fixing one end 107a of the main rope 107.

[0035] 3 and 4, the upper support portion 122 has first upper support portions 122a and 122b fixed to the car guide rail 109Aa and second upper support portions 122c and 122d fixed to the counterweight guide rail 109Bb. The first upper support portions 122a and 122b extend from one end portion of the hoisting machine 102 in the width direction (y-axis direction) toward the center of the hoisting machine 102. The second upper support portions 122c and 122d extend from the other end portion of the hoisting machine 102 in the width direction (y-axis direction) toward the center of the hoisting machine 102.

[0036] The first upper support parts 122a, 122b have a guide rail side fixing member 122a fixed to the side of the car guide rail 109Aa, and a hoist side extension member 122b fixed to the guide rail side fixing member 122a and extending from the guide rail side fixing member 122a toward the hoist 102. The guide rail side fixing member 122a and the hoist side extension member 122b each have two sides that are bent vertically, and are connected with one side facing the other.

[0037] The other side of the guide rail side fixed member 122a and the other side of the hoist side extension member 122b each extend from the connection between the guide rail side fixed member 122a and the hoist side extension member 122b toward the opposite side. The other side of the guide rail side fixed member 122a is connected to the car guide rail 109Aa. The other side of the hoist side extension member 122b extends to the front surface of the hoist 102 and abuts against the front surface of the hoist 102 via an elastic body (elastic member) 124. That is, the hoist 102 abuts against the hoist side extension member 122b with the elastic body (elastic member) 124 sandwiched therebetween.

[0038] The elastic body 124 is connected to the hoist side extension member 122b by a connecting member 129. The elastic body 124 is held to the hoist side extension member 122b by the connecting member 129, and movement of the elastic body 124 relative to the hoist side extension member 122b is restricted. The connecting member 129 may be, for example, a bolt and a nut, but is not limited to a bolt and a nut.

[0039] The guide rail side fixed member 122a and the hoist side extension member 122b can be manufactured at low cost by using equal leg angle iron or unequal leg angle iron.

[0040] The second upper support parts 122c, 122d have a guide rail side fixing member 122c fixed to the side of the counterweight guide rail 109Bb, and a hoist side extension member 122d fixed to the guide rail side fixing member 122c and extending from the guide rail side fixing member 122c toward the hoist 102. The guide rail side fixing member 122c is made of a flat plate and is connected with the flat plate surface facing the counterweight guide rail 109Bb. The hoist side extension member 122d is made of a member having two sides that are bent vertically, and one of the two sides is connected with the guide rail side fixing member 122c facing the guide rail side fixing member 122c.

[0041] The counterweight guide rail 109Bb and the hoist side extension member 122d are connected to the same surface of the guide rail side fixed member 122c. The other side of the hoist side extension member 122d extends to the front surface of the hoist 102 and abuts against the front surface of the hoist 102 via an elastic body (elastic member) 124. That is, the hoist 102 abuts against the hoist side extension member 122d with the elastic body 124 sandwiched therebetween.

[0042] The elastic body 124 is connected to the hoist side extension member 122d by a connecting member 129. The elastic body 124 is held to the hoist side extension member 122d by the connecting member 129, and movement of the elastic body 124 relative to the hoist side extension member 122b is restricted. The connecting member 129 may be, for example, a bolt and a nut, but is not limited to a bolt and a nut.

[0043] The guide rail side fixing members 122a, 122c and the hoist side extending members 122b, 122d are fastened by fastening members 125. The fastening members 125 are composed of a bolt and a nut. The fastening members 125 may be composed of a bolt and a thread groove formed in either the guide rail side fixing members 122a, 122c or the hoist side extending members 122b, 122d.

[0044] The bolt insertion holes formed in either the guide rail side fixing members 122a, 122c or the hoist side extension members 122b, 122d are elongated holes having a longitudinal direction in the x-axis direction (the rotation axis direction 102bx of the sheave 102b). In this embodiment, the bolt insertion holes 122a1, 122c1 of the guide rail side fixing members 122a, 122c are elongated holes.

[0045] By making the bolt insertion holes 122a1, 122c1 elongated holes having a longitudinal direction in the x-axis direction, it is possible to enable relative displacement in the rotation axis direction (x-axis direction) 102bx between the guide rail side fixing members 122a, 122c and the hoist side extension members 122b, 122d. The bolt insertion holes 122a1, 122c1 constitute an adjustment unit that changes the interval (distance) in the x-axis direction between the hoist side extension members 122b, 122d and the front surface of the hoist 102. Therefore, the elevator device 100 of this embodiment has first adjustment units 122a1, 122c1 that adjust the interval (distance) in the x-axis direction between the hoist side extension members 122b, 122d and the front surface of the hoist 102.

[0046] That is, in the elevator device 100 of this embodiment, The guide rail side fixing members 122a, 122c and the hoist side extension members 122b, 122d are fixed by fastening members (bolts and nuts) 125. At least one of the guide rail side fixing members 122a, 122c and the hoist side extension members 122b, 122d has elongated holes 122a1, 122c1 having a longitudinal direction in the rotation axis direction (x-axis direction) 102bx as a bolt insertion hole, The first adjustment portions 122a1 and 122c1 are formed by elongated holes 122a1 and 122c1.

[0047] As described above, in the elevator device 100 of this embodiment, The upper support portion 122 has guide rail side fixing members 122a, 122c fixed to the guide rails 109Aa, 109Bb, and hoist side extension members 122b, 122d fixed to the guide rail side fixing members 122a, 122c and extending from the guide rail side fixing members 122a, 122c toward the hoist 102, The first adjustment portions 122a1, 122c1 enable relative displacement in the rotation axis direction (x-axis direction) 102bx between the guide rail side fixed members 122a, 122c and the hoist side extension members 122b, 122d.

[0048] 4 and 5, the hoist-side extension members 122b and 122d have a screw hole 122e for a jack bolt at a portion facing the hoist 102. A jack bolt (not shown) is screwed into the screw hole 122e for a jack bolt from the left side of the paper surface of FIG.

[0049] 5, when the main rope 107 is wound around the sheave 102b, the hoisting machine 102 receives a hanging load A of the main rope 107 and falls forward as shown by the arrow B. The amount of this falling (inclination) of the hoisting machine 102 needs to be adjusted so as to fall within a predetermined range.

[0050] A method for adjusting the amount of tilt of the hoisting machine 102 will be described with reference to Figs. Fig. 6 is an enlarged view of a portion VI in Fig. 5. Fig. 7 is a front view and a side view of an adjustment plate 128 used to adjust the amount of inclination of the hoisting machine 102. The method of adjusting the amount of inclination by the hoist-side extension member 122b is similar to the method of adjusting the amount of inclination by the hoist-side extension member 122d.

[0051] 6, in order to adjust the amount of inclination of the hoist 102, thin adjustment plates (liners) 128 are sandwiched between the hoist-side extension members 122b, 122d and the elastic body 124 to push back the fallen hoist 102. A necessary number of adjustment plates 128 are sandwiched between the hoist-side extension members 122b, 122d and the elastic body 124 to keep the amount of inclination (amount of tilt) of the hoist 102 within a predetermined range.

[0052] The hoist side extension members 122b, 122d abut against the front surface of the hoist 102 via the adjustment plate 128 and the elastic body 124, suppressing the tilt (inclination) of the hoist 102, thereby keeping the amount of tilt (inclination) of the hoist 102 within a predetermined range.

[0053] 7, the adjustment plate 128 has a slit 128a extending in the vertical direction. The adjustment plate 128 is locked to the connecting member 129 by engaging the slit 128a with a bolt of the connecting member 129. A necessary number of adjustment plates 128 for keeping the tilt amount (inclination amount) of the hoisting machine 102 within a predetermined range are locked to the connecting member 129. The outer shape of the adjustment plate 128 in this embodiment is rectangular, but is not limited to a rectangular shape.

[0054] In this embodiment, the hoist side extension members 122b and 122d are separate members, but the hoist side extension members 122b and 122d may be formed as a single member. In other words, the hoist side extension members 122b and 122d may be connected to each other. Fig. 8 is an enlarged view of part VI in Fig. 5, and shows a state in which the jack bolt 130 is screwed into the jack bolt screw hole 122e of the hoisting machine side extension members 122b and 122d. Fig. 9 shows a state in which the jack bolt 130 is screwed into the jack bolt screw hole 122e from the state shown in Fig. 8.

[0055] 5, when the main rope 107 is wound around the sheave 102b, the hoist 102 receives the suspended load A of the main rope 107 and falls forward (towards the sheave 102b). If the amount of this falling (inclination) of the hoist 102 does not fall within a predetermined range, it is necessary to insert an adjustment plate 128 between the hoist-side extension members 122b, 122d and the elastic body 124 to keep the amount of falling within the predetermined range.

[0056] In addition, the amount of elastic body 124 crushed by the fallen hoist 102 is not necessarily uniform between the hoist side extension members 122b and 122d due to the manner in which the hoist 102 falls and the unevenness of the elastic body 124. Therefore, the number of adjusting plates 128 inserted between the hoist side extension member 122b and the elastic body 124 is not necessarily the same as the number of adjusting plates 128 inserted between the hoist side extension member 122d and the elastic body 124.

[0057] In order to insert the adjustment plate 128 between the hoisting machine side extension members 122b, 122d and the elastic body 124, it is necessary to raise the hoisting machine 102, which is tilted under the hanging load A of the main ropes 107. However, it is not easy to raise the hoisting machine 102, which is leaning against the hoisting machine side extension members 122b, 122d under the hanging load A of the main ropes 107. For this reason, it was necessary to remove the hanging load A from the sheave 102b and adjust the amount of tilt of the hoisting machine 102.

[0058] In this embodiment, as shown in Fig. 8, the hoist side extension members 122b, 122d are provided with jack bolt threaded holes 122e. By screwing a jack bolt 130 into the jack bolt threaded hole 122e, the hoist 102 is pushed back by the hoist side extension members 122b, 122d via the elastic body 124, as shown in Fig. 9. At this time, a size δ is secured in the gap between the hoist side extension members 122b, 122d and the elastic body 124 so that the number of adjustment plates 128 required to keep the amount of tilt within a predetermined range can be sandwiched therein.

[0059] The positions of the hoisting machine side extension members 122b, 122d in the x-axis direction change due to the accumulation of installation errors of the elevator device 100. At this time, the first adjustment units 122a1, 122c1 make it possible to adjust the hoisting machine side extension members 122b, 122d so that they abut against the front surface of the hoisting machine 102 via the elastic body 124. In this case, the first adjustment units 122a1, 122c1 can be regarded as an interval adjustment unit (distance adjustment unit) that changes the interval (distance) in the x-axis direction between the hoisting machine side extension members 122b, 122d and the front surface of the hoisting machine 102 before applying the suspended load A to the sheave 102b of the hoisting machine 102.

[0060] The jack bolt screw hole 122e and the jack bolt 130 are a second adjustment portion that changes the interval (distance) between the hoisting machine side extension members 122b, 122d and the front surface of the hoisting machine 102 in the x-axis direction. That is, in the elevator device 100 of this embodiment, The second adjustment portion is composed of a jack bolt threaded hole 122e formed in the hoisting machine side extension members 122b, 122d, and a jack bolt 130 screwed into the jack bolt threaded hole 122e.

[0061] In particular, the screw hole 122e for the jack bolt and the jack bolt 130 can be regarded as a spacing adjustment part (distance adjustment part) that adjusts the spacing (distance) in the x-axis direction between the hoist side extension members 122b, 122d and the front surface of the hoist 102 when a hanging load A is applied to the sheave 102b of the hoist 102.

[0062] That is, in the elevator device 100 of this embodiment, The hoist support section 120 has a lower support section 121 arranged below the hoist 102, an upper support section 122 arranged at an upper portion of the hoist 102 in a position facing the surface on the sheave 102b side (the front surface of the hoist 102), and first adjustment sections 122a1, 122c1 and second adjustment sections 122e, 130 that adjust the distance between the upper support section 122 and the surface on the sheave 102b side in the rotation axis direction (x-axis direction) of the sheave 102b, The second adjustment parts 122e and 130 make it possible to adjust the interval while the main rope 107 is wound around the sheave 102b.

[0063] According to this embodiment, the amount of inclination of the hoisting machine 102 can be adjusted without releasing the suspended load.

[0064] Furthermore, the elevator device 100 of this embodiment has The lifting body 104, 105 includes a car 104 and a counterweight 105. The guide rail 109 includes a car guide rail 109A (109Aa) for guiding the elevator car 104 as it ascends and descends, and a counterweight guide rail 109B (109Bb) for guiding the counterweight 105 as it ascends and descends. The upper support portion 122 includes first upper support portions 122a and 122b provided on the car guide rail 109Aa side, and second upper support portions 122c and 122d provided on the counterweight guide rail 109B (109Bb) side, The first upper support portions 122a, 122b include a guide rail side fixing member 122a fixed to the car guide rail 109Aa side, and a hoist side extension member 122b fixed to the guide rail side fixing member 122a and extending from the car guide rail 109Aa side toward the hoist 102 side, The second upper support portions 122c, 122d include a guide rail side fixing member 122c fixed to the side of the counterweight guide rail 109Bb, and a hoist side extension member 122d fixed to the guide rail side fixing member 122c and extending from the side of the counterweight guide rail 109Bb toward the side of the hoist 102, The hoist-side extension member 122b of the first upper support portions 122a, 122b and the hoist-side extension member 122d of the second upper support portions 122c, 122d are configured as separate members.

[0065] According to this embodiment, the amount of inclination of the hoist 102 can be adjusted separately on the side of the first upper support portions 122a, 122b and the side of the second upper support portions 122c, 122d.
