FIG. 8 and FIG. 10 to FIG. 12 are enlarged views of the main part for explaining how to remove the receiving part provided in one embodiment of the elevator lifting body according to the present invention.

  As shown in FIG. 7, the employee 9 according to one embodiment of the present invention has a car 15 including a car frame 14 that needs to be supported on a guide rail, or a bottom of a lifting body including a counterweight frame 7. Abutting portions 9a that support the guide rail so that these lifting bodies are not displaced downward, and are fixed to the guide rail, and are disposed outside the horizontal projection surface of the lifting body, and the receiving portion 9a is detachable. It is the structure provided with the attachment part 9b attached to 1 and the connection body 9c which connects the receiving part 9a and the raising / lowering body. In the following description, it is assumed that the lifting body is, for example, the counterweight frame 7.

  The receiving portion 9a described above is formed with a receiving portion piece 91a in which a receiving portion through hole 92a through which the connecting body 9c is inserted is formed and detachably fitted to the mounting portion 9b.

  The mounting portion 9b described above is formed in a substantially C-shape, and a C-shaped body 91b that contacts the back surface of the counterweight guide rail 2 and a contact of the C-shaped body 91b to the counterweight guide rail 2 A rail clip 911b, which is provided on the side surface and holds the guide rail 2 between the C-shaped body 91b and extends from the end of the C-shaped body 91b, and is fitted with the receiving piece 91a. A pair of arm members 93b having a groove 931b and an arm through hole 932b, and a fastener 92b made of a bolt and a nut for fastening and fixing the pair of arm members 93b and the end of the C-shaped body 91b, respectively. ing. Note that the arm through hole 932b is formed in, for example, one of the pair of arm members 93b.

  The connecting body 9c described above includes a first ring 91c inserted into the receiving portion through hole 92a, a second ring 92c inserted into the first ring 91c, and inserted into the arm through hole 932b. The second ring 92c includes a connecting ring (shackle) 93c that detachably connects both ends of the second ring 92c.

  Here, during the transportation of the employee 9, as shown in FIG. 7, with the second ring 92 c inserted into the first ring 91 c, both ends of the second ring 92 c are connected by the connecting ring 93 c. What is necessary is just to connect, and if it does in this way, loss of the receiving part piece 91a can be prevented. Moreover, if the fastener 92b is removed, disassembled and transported, the occupied area during transport can be reduced and transported easily.

  A method of supporting the counterweight frame 7 by the above-mentioned employee 9 will be described in detail with reference to FIGS.

  First, the attaching portion 9b of the receiving employee 9 is attached to the counterweight guide rail 2 by holding the counterweight guide rail 2 with the rail clip 911b.

  Next, after the bottom of the counterweight frame 7 is brought into contact with and supported by the receiving piece 91a, the connecting ring 93c is removed, the second ring 92c is removed from the arm through hole 932b, and the removed second ring 92c is removed. Is inserted into the counter through hole 71 formed in the counterweight frame 7, and both ends of the second ring 92c are connected again by the connecting ring 93c. Thereby, the counterweight frame 7 and the receiving piece 91a are connected by the connecting body 9c.

  Here, except for the first ring 91c, the arm through hole 932b and the receiving portion through hole 92a or the receiving portion through hole 92a and the counter through hole 71 may be connected by the second ring 92c. Although it is conceivable, considering the margin for attaching and detaching the second ring 92c, the workability can be improved by providing the first ring 91c.

  As described above, when the counterweight frame 7 and the receiving piece 91a are connected by the connecting body 9c, the hoisting machine 6 is driven via the main rope 12 as shown in S13 of FIG. Then, the car 15 is lowered, the counterweight frame 7 is raised accordingly, and the receiving piece 91a of the payer 9 connected to the counterweight frame 7 can be removed as shown in FIG.

  In this way, the car 15 and the counterweight frame 7 can freely move up and down without interfering with the employee 9 as shown in FIG. In this state, the car 15 is lifted up to the middle floor where it is in the same position as the weight frame 7, and after the remaining car parts such as a door machine (not shown) are assembled, the remaining rated (total) weight is reduced to half. A corresponding number of weights 7b are loaded onto the counterweight frame 7 (S14 in FIG. 13).

  Here, the remaining portion of the receiver 9 from which the receiving piece 91a has been removed, that is, the mounting portion 9b remains attached to the counterweight guide rail 2, but the mounting portion 9b can be lifted and lowered as described above. Since the counterweight frame 7 to be formed is disposed outside the horizontal projection surface, there is no problem in raising and lowering the lifting body.

  Finally, as shown in FIG. 6 described above, the car 15 is raised to the mounting position of the employee 9, and the remaining portion of the remaining employee 9, that is, the attaching portion 9b is removed from the top of the car 15. Then, the series of work is finished (S15 in FIG. 13).

  According to one embodiment of the elevator lifting / lowering body according to the present invention used in the elevator rope hanging method as described above, when necessary, the mounting portion 9b is fixed to the counterweight guide rail 2, and this mounting portion is fixed. With the receiving portion 9a attached to 9b, the counterweight frame 7 can be supported on the counterweight guide rail 2 by the receiving portion 9a. When it is not necessary to support the counterweight frame 7, the counterweight frame 7 is lifted so that the receiving portion 9 a is removed from the attachment portion 9 b via the connecting body 9 c, and the counterweight frame 7 can freely travel. It becomes possible. In this case, since the attachment portion 9b is disposed outside the horizontal projection surface of the counterweight frame 7, it does not hinder the lifting / lowering of the counterweight frame 7.

  Next, another example of an elevator rope hanging method using the elevator lifting body according to the present invention will be described with reference to FIGS. FIGS. 14 to 17 are vertical sectional views of hoistway for explaining another example of the elevator rope hanging method, and FIG. 18 is a diagram for explaining how to remove the receiving part of the hire employed in another example of the elevator rope hanging method. FIG. 19 is an operation flowchart in another example of the elevator rope hanging method.

  Another example of this elevator rope hanging method is that when the rope is hung, the counterweight frame 7 is in the lower part of the hoistway 16 and the car frame 14 in the state before being assembled as the car 15 is placed in the upper part of the hoistway 16. It is characterized in that it is positioned at the position, and the mutual position of the elevating body is changed from the example of the elevator rope hanging method described above.

  In the operation flow of FIG. 19, S21 to S23 are the same as S1 to S3 in the example of the elevator rope hooking method described above, and thus the description thereof is omitted here.

  First, as shown in FIG. 14, the counterweight frame 7 is carried into the hoistway 16 and arranged near the lowermost landing 17 (S24 in FIG. 19).

  Next, as shown in FIG. 15, a plurality of weights 7b and a number corresponding to half of the rated (total) weight are loaded into the counterweight frame 7 from the frame scaffold 3 (S25 in FIG. 19).

  Furthermore, the clamp 10 is attached to the position where the car lower pulley 14a exists when the car frame 14 is assembled in the vicinity of the top floor hall 18 (S26 in FIG. 19).

  Thereafter, as shown by a solid line in FIG. 15, the main rope 12 is pulled out from the rope drum 11 installed on the uppermost landing 18 and the main rope 12 is wound around the upper part of the turning pulleys 5a and 5b from the uppermost part of the frame scaffold 3. After hanging and hanging in a U-shape and wrapping around the counterweight pulley 7a, the end of the main rope 12 on the counterweight frame 7 side is fixed to the pulley beam 5c (1 of S27 in FIG. 19).

  Next, as shown by a broken line in FIG. 15, the main rope 12 between the turning pulleys 5a and 5b is slackened and suspended in a U shape, and the hoisting machine sheave 6a is attached to the hoisting machine sheave 6a as shown by a two-dot chain line in FIG. Wrap (S27-2 in FIG. 19).

  Further, the main rope 12 on the side of the turning pulley 5b is slackened and suspended in a U shape as shown by a broken line in FIG. 15, and temporarily fixed to the clamp 10 as shown by a two-dot chain line in FIG. 15 (FIG. 19). After 3) of S27, the car side end of the main rope 12 is fixed to the pulley beam 5c (4 of S27 in FIG. 19).

  Next, as shown in FIG. 16, the frame scaffold 3 is disassembled to a position where a space in which the car frame 14 can be assembled can be secured at the upper part of the hoistway 16, and the car frame is utilized using the uppermost part of the disassembled frame scaffold 3. The employee 9 that constitutes an embodiment of the present invention is attached to the portion of the car guide rail 1 at a position that can support the bottom of 14 (S28 in FIG. 19).

  Then, as shown in FIG. 17 with the bottom supported by the employee 9, the car frame 14 is assembled (S <b> 29 in FIG. 19), and then the frame scaffold 3 below the car frame 14 is disassembled ( S30 in FIG. 19).

  One embodiment of the employer 9 used in another example of the elevator rope hanging method is the one shown in FIG. 7 described above, but the receiving portion 9a of the employer 9 is connected to the car frame via the connecting body 9c. 14 is connected to the bottom.

  Thereafter, the counterweight frame 7 is lowered, and the car frame 14 is raised in a fishing bottle manner accordingly. Accordingly, as in the example of the rope hanging method described above, as shown in FIG. 18, the receiving portion piece 91a of the employee 9 is also lifted from the attaching portion 9b in conjunction with the car frame 14 via the connecting body 9c and removed. It is.

  Therefore, the car frame 14 can be lowered downward from the receptionist 9, the car frame 14 is lowered to the bottom of the hoistway 16, and the bottom is supported on the car guide rail 1 by the reception not shown. The car 15 is assembled (S32 in FIG. 19).

  Thereafter, the unillustrated employee is removed from the bottom of the hoistway 16 (S33 in FIG. 19), and the car 15 is lifted to the intermediate floor at the same position as the counterweight frame 7, and the remaining car parts such as a door machine (not shown). After assembling, the number of weights 7b corresponding to half of the remaining rated (total) weight is loaded onto the counterweight frame 7 (S34 in FIG. 19).

  Finally, as shown in FIG. 17, the passenger car 15 is raised to the attachment position of the attachment part 9b of the employee 9, and the attachment part 9 of the employee 9 is removed from the passenger car 15 to complete a series of operations ( S35 of FIG. 19).

  In this way, even when the car guide rail 1 is provided with the support 9 and the car frame 14 is supported by the car guide rail 1, the counterweight is provided with the service weight 9 on the counterweight guide rail 2 described above. Similar to the case where the frame 7 is supported by the counterweight guide rail 2, when necessary, the mounting portion 9b is fixed to the car guide rail 1, and the receiving portion 9a is attached to the mounting portion 9b. By this receiving portion 9a, the car frame 14 of the car 15 can be supported by the car guide rail 1. When the car frame 14 of the car 15 is not required to be supported, the car frame 14 of the car 15 is lifted to remove the receiving part 9a from the mounting part 9b via the connecting body 9c. The car frame 14 can run freely. In this case, since the attaching portion 9b is disposed outside the horizontal projection surface of the car frame 14 of the car 15, it does not hinder the car frame 14 of the car 15 from moving up and down.

  As described above, according to one embodiment of the elevator lifting body receiving system according to the present invention, when the elevator 15 including the car frame 14 or the lifting body composed of the counterweight frame 7 is not required to be supported, The support state of the lifting body can be eliminated without intervention. Accordingly, it is possible to reduce the number of workers in the rope hanging work and the like, thereby reducing the work cost.
