  Two trolleys 13 are each provided with a chain block 17 indicating a lifting portion. The chain block 17 has a hook member 17a. A lifting bracket 20 is suspended from the hook member 17a. Two hoisting brackets 20 and 20 are attached to the hoisting machine 100.

[Lifting bracket]
Next, a detailed configuration of the lifting bracket 20 will be described with reference to FIGS. 4 and 5.
4 and 5 are diagrams showing the lifting bracket 20.
As shown in FIGS. 4 and 5, the lifting bracket 20 has a first member 21 and a second member 22. The first member 21 is formed in a substantially flat plate shape with a part bent substantially vertically. The first member 21 has a fixed piece 21a formed in a substantially rectangular shape, and a connection piece 21b that extends substantially vertically from one end in the longitudinal direction of the fixed piece 21a.

  Two first adjustment holes 23, 23 are formed in the fixed piece 21a. The two first adjustment holes 23, 23 are long holes extending along the longitudinal direction of the fixed piece 21a. Further, the two first adjustment holes 23, 23 are formed at a predetermined interval in the lateral direction of the fixed piece 21a, that is, in the vertical direction. A fixing bolt 26 is inserted into the first adjustment hole 23. The two first adjustment holes 23 and 23 and the fixing bolt 26 constitute a first adjustment mechanism 25.

  The fixing bolt 26 is inserted into the first adjustment hole 23 and screwed into an attachment hole for attaching a cover member formed on the side surface portion of the hoisting machine main body 101. Thereby, the first member 21 is fixed to the hoisting machine main body 101 via the fixing bolt 26.

  Further, a connection hole 27 is provided in the connection piece 21b. The connection hole 27 is formed at the end of the connection piece 21b opposite to the end where the fixed piece 21a is continuous. A connection bolt 34 is screwed into the connection hole 27. The first member 21 is fixed to the second member 22 via connection bolts 34.

  The second member 22 is formed in a substantially flat plate shape having a substantially rectangular shape. The second member 22 is provided with a hanging point hole 33 and two second adjustment holes 31 and 31. The second adjustment holes 31, 31 are long holes extending along the longitudinal direction of the second member 22. The two second adjustment holes 31, 31 are formed at a predetermined interval in the width direction of the second member 22. A connection bolt 34 is inserted into the second adjustment hole 31 in order to connect the second member 22 and the first member 21. A second adjustment mechanism 32 is configured by the two second adjustment holes 31 and 31 and the connecting bolt 34.

  The suspension point hole 33 is formed at the end of the second member 22 opposite to the end where the second adjustment hole 31 is formed. A hook member 17a (see FIG. 2) of the chain block 17 is hung on the hanging point hole 33. Thereby, the lifting bracket 20 and the chain block 17 are connected. As shown in FIGS. 4 and 5, the point of contact with the hook member 17a in the suspension point hole 33 is the suspension point K1.

  The first adjustment mechanism 25 can adjust the horizontal position of the suspension point K1 by sliding the first member 21 with the fixing bolt 26 inserted into the first adjustment hole 23 as a fulcrum. The second adjustment mechanism 32 is hung by sliding the second member 22 along the vertical direction with respect to the first member 21 with the connection bolt 34 inserted into the second adjustment hole 31 as a fulcrum. The position of the point K1 in the vertical direction can be adjusted.

2. Next, a method of installing the hoisting machine 100 on the installation stand 180 using the lifting device 10 and the lifting bracket 20 having the above-described configuration will be described.

  The hoisting machine 100 is carried into the machine room 160 by a lifting method using a crane or a lifting method using a guide rail that guides the hoistway 110 and the car 120. Here, a line passing through the center of gravity G1 of the hoisting machine 100 and parallel to the vertical direction is defined as a vertical line N1. A line passing through the center of gravity G1 of the hoisting machine 100 and parallel to the horizontal direction is defined as a horizontal line M1.

  Next, as shown in FIGS. 2 and 3, the lifting device 10 is installed in the machine room 160. Four struts 11 are arranged so as to surround the hoisting machine 100 and are erected from the floor surface 162. At this time, the column 11 is extended in accordance with the height H1 from the floor surface 162 to the ceiling 161 in the machine room 160 in the longitudinal direction of the column 11. Then, the two trolleys 13 and 13 are moved along the trolley beam 12 so that the intermediate position between the two trolleys 13 and 13 is located on the vertical line N1 of the hoisting machine 100. Thereby, when the hoisting machine 100 is lifted, it is possible to prevent the hoisting machine 100 from being inclined in any one of the width directions.

  Next, the two lifting brackets 20, 20 are attached to the attachment holes 101 a for attaching cover members provided on both sides in the width direction of the hoisting machine body 101 using the fixing bolts 26. At this time, the two lifting brackets 20 and 20 are attached to two places excluding the top part which is the upper part in the vertical direction in the hoisting machine 100. In addition, the location where the two lifting brackets 20 and 20 are attached is below the minimum length H3 in the vertical direction in which the trolley 13 provided on the trolley beam 12 and the chain block 17 are combined from the top of the hoisting machine 100. It is preferable that it is attached to. Thereby, the suspension allowance which combined the trolley 13 and the chain block 17 is securable.

  Next, the mounting position of the lifting bracket 20 on the hoisting machine main body 101 is adjusted using the first adjusting mechanism 25. Specifically, the first member 21 is slid along the axial direction of the hoisting machine 100 with the fixing bolt 26 inserted into the first adjustment hole 23 as a fulcrum. 4A and 4B, the suspension point K1 in the lifting bracket 20 is made to coincide with the vertical line N1 in the axial direction of the hoisting machine 100. When the adjustment of the attachment position of the lifting bracket 20 is completed, the fixing bolt 26 is fastened to the first adjustment hole 23 and the attachment hole 101a of the hoisting machine 100.

  Thereby, the hoisting machine 100 can be lifted in a state where the suspending point K1 of the lifting bracket 20 and the vertical line N1 of the hoisting machine 100 match in the axial direction of the hoisting machine 100. As a result, when the hoisting machine 100 is lifted, the moment around the hoisting point K1 caused by the axial distance between the hoisting point K1 and the vertical line N1 can be prevented. It can be prevented from tilting to either side.

  Here, when the first member 21 is fixed to the hoist 100 with one fixing bolt 26, the first member 21 may rotate around the fixing bolt 26. In this example, two first adjustment holes 23 are provided in the first member 21 and fastened and fixed with two fixing bolts 26, thereby preventing the rotation of the first member 21 and the first member 21. It can be firmly fixed to the hoisting machine 100.

  Next, as shown in FIGS. 5A, 5 </ b> B, and 5 </ b> C, the vertical position of the suspension point K <b> 1 of the lifting bracket 20 is adjusted using the second adjustment mechanism 32. Specifically, the second member 22 is slid along the vertical direction with respect to the first member 21 with the connecting bolt 34 inserted into the second adjustment hole 31 as a fulcrum. Then, the suspension point K1 is adjusted so as to be positioned above the horizontal line M1 of the hoisting machine 100 in the vertical direction.

  In order to secure the suspension allowance, it is preferable that the suspension point K1 is close to the horizontal line M1 above the horizontal line M1 of the hoisting machine 100. Or you may adjust so that the suspending point K1 and the horizontal line M1 of the winding machine 100 may correspond.

  Thereby, since the suspending point K1 is located above the center of gravity G1 of the hoisting machine 100, the hoisting machine 100 can be prevented from tilting when the hoisting machine 100 is lifted.

  Further, in order to lower the center of gravity of the hoisting machine 100 downward in the vertical direction, a balance weight may be provided in the hoisting machine 100. Even in this case, the suspension point K1 of the lifting bracket 20 is adjusted so as to be positioned above the position of the center of gravity lowered by the balance weight.

  Furthermore, as shown in FIG. 5C, there is a hoisting machine 100 in which the center of gravity position is greatly deviated downward in the vertical direction when the hoisting machine 100 is different in type or when the hoisting machine 100 is provided with a balance weight. In this case, the second member 22 may be attached so that the hanging point hole 33 is positioned below the first member 21 in the vertical direction. Thereby, the position of the suspending point K1 can be lowered compared with the case where the suspending point hole 33 is disposed above the first member 21 in the vertical direction, and the suspension allowance can be sufficiently secured.

  Then, when the adjustment of the vertical position of the suspension point K1 is completed, the connection bolt 34 is fastened to the second adjustment hole 31 and the connection hole 27. Thereby, the 1st member 21 and the 2nd member 22 are connected firmly. In addition, when the position of the center of gravity G1 of the hoisting machine 100 and the information of the length H3 of the suspension allowance are known in advance, the first member 21 and the second member are attached before the first member 21 is attached to the hoisting machine 100. The attachment position of 22 may be adjusted and the 1st member 21 and the 2nd member 22 may be connected.

  Here, when the first member 21 and the second member 22 are connected by one connecting bolt 34, the second member 22 may rotate around the connecting bolt 34. In this example, two second adjustment holes 31 are provided in the second member 22 and fastened and fixed by two connection bolts 34, thereby preventing the second member 22 from rotating and the first member 21. And the second member 22 can be firmly connected and fixed.

  Next, the hook member 17 a of the chain block 17 is hooked into the hanging point hole 33 of the lifting bracket 20. Then, the hoisting machine 100 is lifted by the lifting device 10 to be higher than the vertical height H2 of the installation table 180. As described above, the position of the suspension point K1 of the lifting bracket 20 is aligned with the vertical line N1 of the hoisting machine 100 in the axial direction, and is disposed above the horizontal line M1 of the hoisting machine 100. Therefore, the hoisting machine 100 can be lifted in a stable state without tilting the hoisting machine 100.

  The hoisting machine 100 is placed on the installation table 180, and the hoisting machine 100 is installed on the installation table 180. When the installation of the hoisting machine 100 on the installation stand 180 is completed, the lifting bracket 20 is removed from the hoisting machine 100. By performing such a process, the installation work to the installation stand 180 in the hoisting machine 100 is completed.

  According to the installation method of the hoisting machine 100 of the present example, the two lifting brackets 20, 20 are attached to both sides excluding the top of the hoisting machine 100. Thereby, even when the height H1 of the machine room 160 is low, the length H3 of the lifting allowance of the lifting device 10 can be secured with a simple configuration.

  Further, the lifting bracket 20 is provided with a first adjustment mechanism 25 and a second adjustment mechanism 32 that can adjust the position of the suspension point K1. Thus, the position of the lifting point K1 of the lifting bracket 20 can be adjusted according to the center of gravity G1 of the hoisting machine 100, and the hoisting machine 100 is lifted in a stable posture without being tilted. be able to.

  Furthermore, the position of the suspension point K1 can be easily adjusted by the first adjustment mechanism 25 and the second adjustment mechanism 32 for other hoisting machines with different positions of the center of gravity G1. The length H3 of the suspension allowance can be ensured.

  The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims.

  For example, in the above-described embodiment, the example in which the two lifting brackets 20 and 20 are attached to the attachment holes 101a provided on both side portions in the width direction of the hoisting machine main body 101 has been described. It is not something. For example, when the mounting holes for the cover member are not provided on both sides in the width direction of the hoisting machine main body 101, mounting holes for attaching the lifting bracket 20 to the hoisting machine main body 101 may be formed.

  Furthermore, although the example which attaches the lifting bracket 20 to the hoisting machine main body 101 of the hoisting machine 100 with the fixing bolt 26 was demonstrated, the attachment method of the lifting bracket 20 is not limited to this. For example, the hoisting machine 100 and the lifting bracket 20 are provided with an engaging claw and an engaging receiving part, and the lifting bracket 20 is attached to the hoisting machine 100 by engaging the engaging claw and the engaging receiving part. It may be.

  Moreover, the location where the lifting brackets 20 and 20 are attached is not limited to both sides in the width direction of the hoisting machine main body 101. For example, the lifting bracket 20 is attached to the brake device 103 of the hoisting machine 100. Also good. Or you may attach the lifting bracket 20 to the sheave 102 which is the both sides of the axial direction of the winding machine 100, and the back part of the winding machine main body 101. As shown in FIG. However, in order to ensure the strength when lifting the hoisting machine 100, it is preferable to attach the lifting bracket to the hoisting machine main body 101 rather than the brake bracket 103 or the sheave 102.

  In addition, when attaching the lifting bracket 20 to the both sides of the hoisting machine 100 in the axial direction, the first adjusting mechanism is configured so that the hanging point K1 of the lifting bracket 20 is in the width direction with respect to the vertical line N1 of the hoisting machine 100. Used to match.

  Furthermore, although the example which comprised the 1st adjustment mechanism 25 and the 2nd adjustment mechanism 32 with the long hole and the volt | bolt was demonstrated, it is not limited to this. As the first adjustment mechanism and the second adjustment mechanism, the first adjustment hole and the second adjustment hole are configured by a plurality of fixing holes formed at predetermined intervals along the axial direction or the vertical direction of the hoisting machine 100. Also good. Alternatively, a plurality of claw portions formed at predetermined intervals along the axial direction or the vertical direction of the hoisting machine 100 and an engagement receiving portion that engages with the claw portions may be used. Further, the second adjustment mechanism that adjusts the position of the suspension point K1 may be configured by providing a plurality of suspension point holes along the vertical direction.

  Moreover, although the example which provided the 2nd adjustment hole 31 of the 2nd adjustment mechanism 32 in the 2nd member 22 was demonstrated, it is not limited to this. For example, the connection piece 21b in the first member 21 may be extended along the vertical direction, the second adjustment hole 31 may be provided in the connection piece 21b, and the connection hole 27 may be provided in the second member 22.

  Although the 1st adjustment mechanism 25 was provided in the connection location of the 1st member 21 and the hoisting machine 100, and the 2nd adjustment mechanism 32 was provided in the connection location of the 1st member 21 and the 2nd member 22, it is limited to this. It is not something. For example, a first adjustment mechanism that adjusts the horizontal position of the suspending point K1 is formed at a connection point between the first member and the second member, and a second adjustment mechanism that adjusts the vertical position of the suspending point K1 is the first. You may form in the connection location of a member and a winding machine.

  Moreover, although the example which attaches the lifting bracket 20 when installing the hoisting machine 100 was demonstrated, you may comprise the hoisting machine to which the lifting bracket 20 was attached previously.

  In the above-described embodiment, the case where the first member 21 and the second member 22 are independent members has been described. However, the first member 21 and the second member 22 are used as hoisting machine brackets of a predetermined model. The two members 22 may be integrally formed. Alternatively, when the first member 21 and the second member 22 are integrally formed, the position of the suspension point may be formed in advance according to the position of the center of gravity of the hoisting machine. If a plurality of such lifting brackets are prepared, adjustment of the lifting bracket and confirmation of the center of gravity of the hoisting machine can be omitted during lifting.

  Furthermore, if the lifting bracket is fixed to the hoisting machine main body by a method such as welding, the work of attaching the lifting bracket at the work site becomes unnecessary. As a result, not only when the hoisting machine is carried in but also when carrying out a future renewal work, it is not necessary to attach a lifting bracket, so that the position of the lifting point matches the center of gravity of the hoisting machine in advance. It is possible to use a suitable adjusted lifting bracket.

  In this specification, words such as “parallel” and “orthogonal” are used, but these do not mean only strict “parallel” and “orthogonal”, but include “parallel” and “orthogonal”. Further, it may be in a state of “substantially parallel” or “substantially orthogonal” within a range where the function can be exhibited.
