Description

  The present invention relates to a lifting method for lifting a heavy object such as an elevator hoist to a high position using an inexpensive general-purpose lifting machine having a small lifting capacity in a high-rise building.

  In recent years, with the increase in the number of buildings, elevators have become faster and larger, and in proportion to this, hoisting machines that drive elevators tend to be larger and heavier. In particular, there are many plans to build more than 100 stories outside of Japan, and this tendency is remarkable.

  Since the elevator hoist installed in such a high-rise building needs to be installed in the machine room on the top floor, how to lift the super heavy object hoist to the machine room on the top floor It has become a big issue.

  However, if it is possible to use a tower crane for construction with a large lifting capacity, this tower crane can lift the hoisting machine, but especially when the capacity of the tower crane is low or a tower crane is installed overseas. In many cases, the hoisting machine using a tower crane cannot be lifted because the construction period does not match.

  Furthermore, in Japan, tower cranes cannot be installed when replacing high-rise elevators in existing buildings, so it was impossible to lift the tower crane.

  Here, as a conventional technique related to a lifting method of a general elevator hoisting machine, for example, according to Patent Document 1, a winch rope from a winch is wound through a pulley and the winch rope is used as a hoisting machine. There has been proposed a method of lifting a hoisting machine toward a machine room at the top of a hoistway by engaging a mounted sling wire and driving a winch.

  Further, as a conventional technique for lifting a heavy object, for example, according to Patent Document 2, in order to increase the lifting capacity, a fixed pulley suspended at a fixed position and a lifting / lowering synchronized with the heavy object to be lifted are performed. There has been proposed a method of providing a moving pulley that lifts up as 2 to 1 roping.

Japanese Patent Laid-Open No. 08-165073 JP 2003-247355 A

  Generally, general-purpose lifting machines (winches) that are commercially available have a limit in the size of the take-up drum that winds up the tow rope, and if the diameter of the take-up drum is increased, the length (lift) of the rope that can be taken up becomes larger. However, the traction force decreases. In order to satisfy both the lifting height and the traction force, the winch body is also increased in size and weight.

  General commercially available winches have a traction of 2 to 5 tons and a rope winding amount (lift) of 200 m. With this capability, a 5 ton elevator hoist can be lifted up to a height of 200 m by 1: 1 roping, or a 10 ton hoist can be lifted up to a height of 100 m (building height of about 25-30 floors) by 2: 1 roping. I can't.

  Therefore, when the above-mentioned general purpose winch is used, the lifting method of the above-mentioned Patent Document 1 can lift 10 to 20-story middle / high-rise elevator hoisting machines. Or, an elevator for a super high-rise building having a higher height is not capable of being applied due to insufficient winch capacity (lift and traction).

  Furthermore, even the lifting method of 2 to 1 roping disclosed in Patent Document 2 described above has a disadvantage that the general-purpose winch cannot cope with the lifting height (lifting height).

  The object of the present invention has been made in view of the above-mentioned disadvantages. In a super-high-rise elevator of 50 to 100 stories or more, a heavy lifting elevator hoisting machine is used for general purpose lifting with a relatively small capacity. An object of the present invention is to provide a lifting method that enables lifting to a machine room at the top of a high altitude building using a winch.

In order to achieve the above object, the present invention provides a lifting method for lifting an elevator hoisting machine used for a super high rise elevator to the top floor machine room of a car hoistway. A step of installing a heavy winch, and a deceleration rope drawn out or wound up from the lifting winch was suspended by a lifting beam via a turn-turning gold wheel installed on a side surface in the car hoistway forming a wrapping by reduction roping between the movable pulley of the lift in conjunction with the fixed pulley and the elevator hoisting machine, and the elevator hoist the be movable pulley and Agekasane lengthwise A step of connecting with a separable suspension rope, a step of hanging a separable temporary holding rope temporarily holding the elevator hoisting machine from the top of the car hoistway, and driving the lifting winch to A step of Agekasane the elevator hoisting machine to the intermediate floor by flops, wherein the step of replacing hanging first temporary holding rope lower the elevator the hoisting machine in the middle floor from the suspension rope, said first separating the lower first suspension rope of the suspended sort of state the suspension ropes to the temporary holding rope connecting the elevator hoisting machine to the first upper second suspension rope suspension rope And lifting the elevator hoisting machine, and after lifting the elevator hoisting machine, the first temporary holding rope is removed, the lifting winch is driven and the suspension rope is more than the intermediate floor. Lifting up to the next intermediate floor, and suspending the elevator hoisting machine from the first suspension rope to the second temporary holding rope above the first temporary holding rope in the next intermediate floor Change Separating the second suspension rope in a state of being suspended to the second temporary holding rope, and suspending the elevator hoisting machine by connecting the elevator hoisting machine to the speed reduction rope side. If, after returning hanging the elevator hoisting machine to the decelerating rope side, and comprising the a step of Agekasane the elevator hoisting machine to the machine room by driving the lifting winch again To do.

  According to the present invention, an expensive large lifting winch is not used, no special reinforcement of the building is required, and a general purpose lifting winch that is inexpensive and relatively small in capacity is used to reach the height of a high-rise building. Super heavy objects such as elevator hoisting machines can be lifted.

  In addition, if the number of lifting stages of the suspension rope is increased, an elevator hoisting machine that is a super heavy object can be installed without using a special lifting winch or reinforcing a building even in a 500m or 800m super high-rise building. It is possible to lift up to a high altitude machine room.

  Lifting cargo (elevator hoisting machine) 23, which is a heavy object, is moved from the elevator hall first floor 1 to the elevator tower (elevating / lowering) by a general-purpose hoisting machine (lifting winch) 12 installed on the elevator hall uppermost floor 4. Road) 7 is lifted up to the elevator machine room 9 provided at the top of the building (the top of the hoistway). Here, the general purpose lifting winch 12 is installed in advance at the landing on the top floor 4. Further, the traction rope 16 and the deceleration rope 17 drawn from the lifting winch 12 are wound between the fixed pulley 14 and the moving pulley 15 to form a deceleration roping.

  FIG. 1 shows a conceptual configuration of a hoisting machine lifting method according to the present embodiment, and the main basic configuration of the hoisting machine lifting method is suspended from a lifting beam 10 (see FIG. 2). The fixed pulley 14, the moving pulley 15 that moves up and down in conjunction with the elevator hoisting machine 23, the traction rope 16 and the reduction rope 17 wound around the fixed pulley 14 and the movement pulley 15, the traction rope 16 and the reduction rope A hoisting machine for lifting (lifting winch) 12 that pulls 17 and an elevator hoisting machine 23 suspended from a movable pulley 15 are provided.

  In the overall cross-sectional view of the elevator shaft (inside the tower) 7 shown in FIG. 2, the present embodiment is for general-purpose lifting where a heavy cargo (elevator hoisting machine) 23 is installed in the uppermost elevator hall 4. A hoisting machine (lifting winch) 13 is used to lift from the first floor 1 of the elevator hall to the elevator machine room 9 at the top of the building (the top of the hoistway) via the elevator tower 7.

  At the time of lifting, for example, using a general purpose lifting winch 12 with 1: 1 towing, traction force of 5 tons, and rope winding amount of 200 m, it is attempted to lift cargo of less than 15 tons into a machine room 9 at a height of 200 m. In this case, since the pulling force of the lifting winch 12 is insufficient, the necessary lifting gravity (15 ton) cannot be obtained unless the roping 17 shown in FIG. 2 is decelerated to 3: 1 (lifting gravity increases) using a pulley. . However, when the roping 17 is decelerated to 3: 1, the lift is reduced to 1/3 (67 m), and the lift cannot be achieved up to a height of 200 m.

  Therefore, in the present embodiment, in order to compensate for the height of lifting, the length of the moving pulley 15 in FIG. 2 is the first of 1/3 (67 m) of the winding amount of the lifting winch 12 of 200 m. Two second suspension ropes 18 and 19 are connected in series, and the lower ends of these suspension ropes 18 and 19 are connected to the cargo (elevator hoisting machine 23).

  At this time, the suspension ropes 18 and 19 may be 40φ thick (breaking factor 97 ton, safety factor 6), but one piece becomes very heavy and handling becomes very difficult. Work is facilitated by hanging a plurality of medium-thick ones with a diameter of about 20φ in parallel.

  In addition, for lifting the cargo (elevator hoisting machine 23) after being wound by the lifting winch 12, the elevator hoisting machine 23 on the lower floor 2 which is the intermediate floor 1 and the upper floor 3 which is the intermediate floor 2 respectively. In order to suspend the vehicle (details will be described later), the first loading rope 24 and the second loading rope 25 are attached to the cargo (elevator hoisting machine 23) side in advance. As a specific configuration, the first and second loading ropes 24 and 25 are connected to the sling rope 22 of the elevator hoisting machine 23.

  Further, the hoistway is necessary when the cargo (elevator hoisting machine 23) wound by the pulling rope 16 and the deceleration rope 17 is suspended between the lower floor 2 and the upper floor 3 by operating the lifting winch 12. A first temporary holding rope 20 and a second temporary holding rope 21 each having a length of 67 m, which is 1/3 of a lifting height of 200 m, are attached to the lifting beam 10 on the ceiling of the machine room 9 located at the top of 7. Are connected in series so that they can be divided. Here, the pre-hanging operation of the first and second temporary holding ropes 20 and 21 is performed using a small winch or the like (not shown).

  In the present embodiment, there is provided a hoisting method for hoisting a super-high-rise elevator that uses a general-purpose lifting winch 12 to lift an elevator hoisting machine 23, which is a heavy object, to a high position of a long lift 5.

(See the illustrated structure). If the lifting winch 12 is wound up by 0.5 to 1 m in this connected state, the load of the elevator hoisting machine 23 moves from the first temporary holding rope 20 side to the second suspension rope 19 side again, The elevator hoisting machine 23 is suspended from the second suspension rope 19 (see the illustrated structure in FIG. 9).

  Here, further using the pulling rod 26, the first load-carrying rope 24 and the first temporary holding rope 20 are drawn together to separate the two ropes 24, 20 (see the illustrated structure in FIG. 10). .

  Next, the process of lifting the elevator hoisting machine 23 to the upper floor 3 which is the elevator hall middle floor 2 by the hoisting machine lifting method according to the embodiment of the present invention will be described with reference to FIGS. This will be described below.

 If the lifting winch 12 is hoisted while the elevator hoisting machine 23 is suspended by the second suspension rope 19 and the second unloading rope 15 at the time of 1/3 lifting of the head shown in FIG. As shown in the illustrated structure of FIG. 11, the machine 23 is lifted up to the intermediate floor 2 that is the upper floor 3.

  When the intermediate floor 2 has been lifted, the pulling rod 26 is used from the elevator hall side of the intermediate floor 2 to pull the first loading rope 24 and the second temporary holding rope 21 together, and Similarly to the description of FIG. 4, the ropes 24 and 21 are connected using a shackle (see the illustrated structure of FIG. 11).

  After the ropes 24 and 21 are connected, if the lifting winch 12 is unwound by 0.5 to 1 m and the elevator hoisting machine 23, which is a lifted cargo, is suspended, the load of the elevator hoisting machine 23 is increased to the second temporary It will move to the holding rope 21 side and will be in the state suspended (refer the illustration structure of FIG. 12).
