Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail installation work support device used for installing a guide rail for guiding a car or a counterweight in an elevator hoistway, and a guide rail installation work using the device. Concerning the law.

[0002]

2. Description of the Related Art Generally, as one of elevator installation work for buildings such as buildings, it is necessary to install a guide rail for guiding a car or a counterweight over the entire length from the bottom to the top of the hoistway. In particular, as buildings have become higher in height as in recent years, the hoistway becomes longer, and many guide rails must be added and attached. Moreover,
If the multiple guide rails are connected outside the hoistway to form a long one-rigid rigid body, the guide rails cannot be pulled into the hoistway from a narrow entrance / exit, so all guide rails must be connected inside the hoistway. Are going up in high places.

In the conventional work of installing guide rails, first, a required number of guide rails having an appropriate unit length (usually 4 to 5 m) are installed from the factory to the floor at the bottom entrance of the hoistway of the building (site ) To carry. Each of these guide rails is pulled into the bottom of the hoistway (lower end pit) by a lifting machine and temporarily placed in a leaning position.

Next, a temporary scaffold is built up in the hoistway to a high level, and a worker rides on the temporary scaffold, and the first guide rail temporarily placed as described above is used for one rail by a hoist at the top of the hoistway. Lift to a height equivalent to the length of. Then, an operator riding on the temporary scaffolding joins the lower end of the first guide rail with the upper end of the second guide rail while aligning the upper ends of the second guide rails, and joins them together with a joint plate and a plurality of bolts. Connect with fasteners such as nuts. In this state, operate the lifting machine again and lift the first guide rail and the second guide rail together,
After being lifted to a height corresponding to the length of one of the second guide rails, the third guide rail is connected to the lower end in the same manner as described above.

By repeating the lifting and connecting work in this manner, the required number of guide rails are connected and lifted and held along a predetermined rail attachment position on the inner wall of the hoistway. In this state, an operator who rides on the gondola temporarily fixes the series of guide rails to a predetermined rail-attached position on the inner wall of the hoistway while fastening the rail brackets and rail clips. Finally, the series of guide rails are centered and adjusted in a vertical state without steps, and finally fixed and fixed, whereby the installation work is completed.

[0006]

By the way, in the above-described conventional work for attaching a guide rail, a guide rail that is carried into the bottom of the hoistway and temporarily placed in a leaning state is equivalent to the length of one rail by a lifting machine. The guide rail is lifted to a predetermined height in the hoistway by connecting the upper end of the next guide rail to this lower end by connecting the upper end of the next guide rail with a joint plate and multiple fasteners such as bolts and nuts. However, it is necessary to connect the guide rails one after another at the high places.

In order to perform the guide rail connecting work at a high place in the hoistway, a high temporary scaffold such as a yagura on which the worker rides is required, and the worker is unstable and is at a high risk of falling, and is dark. , The working environment is very bad. In addition, the ends of the guide rails are precision machined and it is necessary to carry out the connection work while carefully handling the finished surface, and the guide rails are very heavy (30 to 150 kg).
As described above, it was inefficient because it was very difficult to perform the connecting work at a high place in the hoistway, which was dark and had a very bad working environment.

[0008] Further, it is troublesome to unload the rail brackets for fixing a series of hoisted guide rails to the inner wall of the hoistway at each place height, and at the same time, the rail brackets are used to lift the rail brackets at each place height. Since the work of fastening each to the guide rail with the clip and the fastener is also at a high place, it was a troublesome work.

Therefore, in order to improve the efficiency of the setup work, the rail bracket is previously fastened and fixed to the required portion of each guide rail with a rail clip and a fastener, and in this state, each guide rail is carried in and hoisted in the hoistway. It is desirable to connect the rails one by one while sequentially connecting them, but in such a case, if a number of guide rails with rail brackets are erected in the hoistway and temporarily placed, the rail brackets of the guide rails may be caught or Since the rail bracket is caught on various beams and fastener plates on the inner wall of the hoistway, it is troublesome to handle, and the work of hoisting one by one and sequentially connecting them while hoisting along the predetermined rail attachment position on the inner wall of the hoistway is possible. Very difficult.

Thereafter, similarly to the above, using the rail loading table 10, the guide rail 101 of the B1 part of the first basement floor is dropped into the hoistway 2 to be vertically loaded and supported, and this is lifted by another hoist 60A above the hoistway 2. The rail is lifted up by one rail via the heavy equipment rope 61A, and then the guide rail 102 of the second basement B2 portion is dropped into the hoistway 2 in the same manner as above to carry in and support the guide rail 102 vertically.
The upper end of the guide rail 101 is positionally adjusted to the front, rear, left and right, and the height is adjusted to join the lower end of the guide rail 101, and both of them are aligned and connected as described above. In this state, the other lifting machine 60A is operated to operate the guide rails 101, 102.
Is lowered by one rail, and the guide rails 101 and 102 of these underground portions are supported by the rail guide support mechanism 20 and the height control mechanism 40 of the rail loading table 10. Then, from the upper end of the guide rail 101, the lifting machine rope 61
Remove A.

Thus, in the state shown in FIG. 15, the upper end of the guide rail 101 in the underground portion is adjusted to the front, rear, left and right in the same manner as described above, and the height is adjusted to join the lower end of the guide rail 1 in the ground portion. The cores are aligned and connected as described above. With this, the guide rails at the bottom pit of the hoistway can be left, and all the required number of guide rails can be lifted up and down in the hoistway 2 all at once.

When another lifting machine 60A cannot be prepared as described above, the rail carrying table 10 and the lifting machine 60 are used to carry in the guide rails 1 ...
After connecting and hoisting work, the hoisting rope 61 of the hoisting machine 60 is temporarily temporarily fixed to the top beam of the hoistway 2 or the like and removed from the hoisting machine 60, and another rope is wound on the hoisting machine 60. Then, by utilizing this, the guide rails 101 and 102 in the underground portion can be lifted at the time of carrying in, as described above.

As described above, the landing doorway 5 in the hoistway 2 with the guide rails at the lowermost pit of the hoistway being left and all the required number of guide rails being connected to each other.
After being vertically lifted near the vicinity, a series of these guide rails 1 to 102 are installed at predetermined rail mounting positions D on the inner wall of the hoistway 2 as shown in FIG. 3 (the left and right guide rail mounting positions for the car and the counterweight). (Either of the left and right guide rail installation positions) for the work. A fastener plate 64 for joining and fixing the brackets 4 attached to the guide rails 1 to 102 is fixed in advance at a predetermined rail attachment position D on the inner wall of the hoistway 2 with a space in the vertical direction. .

The operation of suspending the guide rails 1 to 102 at the predetermined rail attachment position D is performed by two-step lateral movement as shown by arrows a and b in FIG. First, for the lateral movement of the arrow a, as shown in FIG. 16, the lifting machine 60B is arranged in the upper part of the hoistway 2 near the rail attachment position D. This lifting machine rope 61B is connected to the uppermost ends of a series of guide rails 1 to 102 suspended by the lifting machine rope 61 of the preceding lifting machine 60 in the vicinity of the entrance and exit of the hoistway 2 as shown by an imaginary line. Then, the hoist 60B is operated to pull up the hoist rope 61B. With this, the tension of the lifter rope 61B is increased to balance with the tension of the previous lifter rope 61, and when the lifter rope 61B is further pulled up,
The front lifter rope 61 is loosened, and as shown by the solid line in FIG. 16, a series of guide rails 1 to 102 are laterally moved while being pulled up diagonally to the vicinity of the front of a predetermined rail attachment position D.

Next, the series of guide rails 1 to 102
Is horizontally moved as indicated by an arrow B in FIG. This is performed by sliding the lifting machine 60B from the position of the imaginary line to the position of the solid line with respect to the slide base 65 as shown in FIG.
A series of guide rails 1 to 102 are horizontally translated so that the rail brackets 4 overlap the upper surface of each fastener plate 64 on the inner wall of the hoistway 2. The rail brackets 4 are temporarily fixed to a position slightly higher than the specified position of the guide rail 1 so as not to interfere with the fastener plate 64 during the lateral movement. In this way, the series of guide rails 1 to 102 is suspended and held at the prescribed height of the predetermined rail attachment position D.

When the arrow A shown in FIG. 16 is moved laterally, the series of guide rails 1 to 102 move like a pendulum so that the rail bracket 4 contacts the fastener plate 64 on the inner wall of the hoistway 2. If a problem such as
Both the former lifting machine 60 and the next lifting machine 60B are operated while controlling them slowly to reduce the pendulum motion. Further, if the series of guide rails 1 to 102 can be moved horizontally substantially at the specified height without being vertically moved by the control operation of the both lifting machines 60 and 60B, the length of the series of guide rails up to the above can be achieved as much as possible. The guide rail 103 (see FIG. 21) at the lowermost pit portion that is finally connected to the lower end of the guide rail 103 can be made short and short. 18 to 20 show another work method for suspending the guide rails 1 to 102 from the vicinity of the entrance / exit of the hoistway 2 to a predetermined rail attachment position.

In this case, first, as shown in FIG. 18, a jig 71 having a hook 71a is installed on the floor beam or the like of the upper end machine room 2a of the hoistway 2. This is just above the predetermined rail attachment position in the hoistway 2. The hanging gold wheel 72 is hooked on the hook 71a of the jig 71. On the other hand, even in a building, a hoisting machine 60C such as a hoisting machine is installed on the uppermost floor Fn, the hoisting rope 61c is wound around the hoisting wagon 72 and hung down, and the midway of the hanging part of the rope 61c is the highest. From the floor, a pulling wagon 74 using a chain block 73 pulls the hoistway 2 toward the landing doorway side. This lower end hook of the hoist rope 61c
As described above, it is attached to the lifting metal fitting 75 fixed to the upper end of the uppermost guide rail 1 dropped into the hoistway 2 and carried in. In this way, the lifting machine 60C is operated to wind up the lifting machine rope 61c, so that a large number of connected guide rails 1 ... Are lifted along the vicinity of the landing entrance / exit in the hoistway 2.

Finally, a suspending rope 78 for suspending the series of guide rails 1 ... To the hook 76 such as the ceiling of the machine room 2a is passed from the machine room 2a to the top floor in advance. When the upper ends of the series of guide rails 1 ... Are pulled up to the vicinity of the landing entrance / exit 5 of the uppermost floor Fn, the lower end hooks of the hanging ropes 76 are hooked on the upper end lifting metal fittings 75. When the ceiling hook 76 cannot be prepared, as shown by the chain double-dashed line, the machine room 2a
The hook 76 'is prepared through the pedestal 79.

Thus, as shown in FIG. 19, the lifting machine 6
0C is operated to wind up the hoisting machine rope 61c, loosen the chain block 73, and pull up the series of guide rails 1 ... And laterally move it, and suspend it near the predetermined rail attachment position immediately below the jig 71.

At this time, the end hooks of the pair of posture operating ropes 80, 81 are hooked on the eyebolts protruding to the left and right of the lifting metal fitting 75 at the upper end of the guide rail 1 so that both ropes 80, 81 are at the top. A worker pulls from the floor Fn to control the swing and direction of the series of the guide rails 1 ... so that the rail bracket 4 does not interfere with the fastener plate 64 on the inner wall of the hoistway 2.

In this way, as shown in FIG. 20, the chain block 82 is pulled from the hook 76 such as the ceiling of the machine room 2a.
Is used to pull up the suspension rope 78 to suspend the series of guide rails 1 ... Then, the weight of the series of guide rails 1 ... Is all applied to the neighborhood rope 78, and when the jig 71, the lifting wagon 72, and the lifting machine rope 61c are free, the jig 71, the lifting wagon 72, and the lifting machine rope are provided. 61c and the hoisting safe 30 are moved to a position above the next predetermined rail attachment position to be on standby, and at the same time, a worker pulls the left and right posture operation ropes 80 and 81,
A series of guide rails 1 ... Is rotated so that the rail bracket 4 is attached to the fastener plate 64 on the inner wall of the hoistway 2.

Next, the loading of the guide rail 103 at the lowermost pit of the hoistway 2 will be described with reference to FIG. The guide rail 103 at the lowermost stage has a pendulum-like movement and a diagonally upward pulling movement when the guide rails 1 to 102 are laterally moved from near the landing doorway in the hoistway 2 to a predetermined rail attachment position. Out of the way,
It will be delivered at the end separately. Therefore, the lowermost guide rail 103 may be shorter than the standard guide rail (4 to 5 m). The lowermost guide rail 103 may be omitted if the length of the series of guide rails 1 to 102 lifted in the above-mentioned loading operation is already sufficient.

FIG. 21 shows an example of carrying in the lowermost guide rail 103 by using the above-mentioned guide rail attached work supporting device. First, similarly to the case shown in FIGS. 1 and 2, the lowermost guide rail 103 is placed on the rail loading table 10 and conveyed to the landing doorway 5 of the first floor F1 where the lowermost guide rail 103 is railed. While being guided by the guide support mechanism 20, the lengths of the pulling ropes 32 and 42 of the angle control mechanism 30 and the height control mechanism 40 are gradually changed to control them so that they can be dropped into the hoistway 2 and brought up vertically. Then, by extending the lengths of the tow ropes 32 and 42 as they are, the lowermost guide rail 103 is lowered into the lowermost pit portion. The loading operation of the lowermost guide rail 103 into the pit portion may be carried in from the basement floor using a simple lifting machine as in the conventional case.

Here, a worker pushes up the lowermost guide rail 103 carried into the pit portion while controlling the posture by a manual work or the like, and the upper end of the guide rail 103 is suspended first. Align and join to the lower end of No. 102. At the time of this centering joining, moving the series of previously suspended guide rails 1 to 102 has a considerable weight, and the joint plate 3 connecting the rails is bent or buckled. It is difficult because it may happen. Therefore, the lowermost guide rail 103 is pulled up by the pulling ropes 32 and 42 of the angle control mechanism 30 and the height control mechanism 40, or pushed up by using a separately prepared jack (not shown). Then, the upper end of the lowermost guide rail 103 is connected to the lower end of the upper guide rail 102. This connection work is performed manually in the pit portion as in the conventional case.

Finally, as shown in FIG. 22, a series of guide rails 1 to 103 suspended at the predetermined rail attachment positions on the inner wall of the hoistway 2 as described above are aligned so that they are in a vertical state without any step. The rail brackets 4 are adjusted so that the rail brackets 4 are fixed to the fastener plates 64 on the inner wall of the hoistway 2 by full tightening. This centering and fixing work is performed by a worker on a gondola or a hoistway work robot 90. The robot 90 is, for example, Japanese Patent Laid-Open No. 58-1938.
As shown in Japanese Patent Laid-Open No. 76, the guide rail is automatically centered, positioned and fixed while moving up and down in the hoistway 1.

With the guide rail installation work support device of the above-described embodiment, the guide rail 1 can be placed on the rail loading table 10 and transported to the elevator hall entrance / exit 5. Therefore, the guide rails 1 ... It is convenient to temporarily put it in a place where it does not interfere with other work such as in the lobby, and carry it from there at any time.

Also, the traveling and angle control mechanism 30 of the rail loading table (carriage) 10 of the guide rail installation work support device.
If the towing machines 31, 41, etc. of the height control mechanism 40 are manually operated, they are basically unpowered, and preparation of a power source or the like is unnecessary.

Further, the work supporting device provided with guide rails not only supports the carrying-in and connecting work of the guide rails 1 to 102 other than the lowermost stage into the hoistway 2, but also the lower end pit portion of the lowermost guide rail 103. It can also support the work of bringing in.

Furthermore, since the guide rail installation work supporting device is provided with the rail position fine adjustment mechanism 50 as shown in FIGS. 9 and 10, the n-th guide which is carried into the hoistway 2 and lifted up. With respect to the lower end of the rail, the upper end of the (n + 1) th guide rail can be easily finely adjusted in the horizontal directions X and Y and the vertical direction Z for reliable centering and joining, and the accuracy of the stop position of the bogie underframe 11 is somewhat. Even if there is a deviation, the rail connecting work can be performed easily and efficiently. in addition,
Since the connecting work can be performed in the vicinity of the elevator hall entrance / exit 5, the rail connecting work itself can be performed using a labor saving means such as a robot.
