Therefore, a limit switch other than the photoelectric switch can be used as the retaining switch 40.

In the tower assembling / disassembling apparatus 20 according to the present embodiment, the top end stand 10 is connected to a power source so that it can be operated independently of the transporter 2. For example, in order to perform an assembling operation to add the steel tower 1, the transporter 2 is lowered to the lowest position, and the wire rope 8 hanging from the counterweight is temporarily removed. Thereafter, a steel tower segment 1A to be added by a tow truck or the like is hung on the front side of the movable base 21 which has been moved down to the bottom by lowering the top series 10 and this steel tower segment 1A
Is raised from the floor of the landing 11 by an appropriate amount,

The tower segment 1 </ b> A held by 5 can be moved onto the existing tower 1. Therefore, when the connection position between the tower segment 1A held by the tower holding means 25 and the existing tower 1 is adjusted, the top connecting column is stacked until the tower segment 1A is stacked on the top surface of the existing tower 1. Lower 10

After the top gantry 10 reaches the required position in this way, the gantry support pieces 18, 18 provided in advance on the top gantry 10 (retreat when ascending and descending so as not to contact the steel tower 1). Is projected to the front of the tower 1 and is engaged with and supported on a horizontal member provided on the front of the tower 1. In this way, the top end stand 10 is supported by the tower supporting lateral members by the end stand supporting pieces 18, 18, and its longitudinal weight is shifted by the guide rollers 17, 17 engaged with the guide rails 1 a, 1 a. Is held
It is fixed stably. Therefore, this top series 10
As a result, safety can be secured without causing an accident such as dropping during the work of adding a steel tower.

When the tower segment 1A is stacked on the tower to be added, the tower supporting piece 25a holding the tower segment 1A is separated from the lower surface of the lateral side member 1c of the tower segment 1A and comes out of the supporting state. Therefore, if all the tower support pieces 25a of the tower holding means 25 are pulled out from the support piece insertion holes 26, the engagement with the tower 1 is released and the tower 1 is free, and the movable table 21 can be moved backward. Therefore, after the tower segment 1A to be replenished is bolted to the existing tower 1, the gantry supporting pieces 18, 1 are connected.
8 is retracted and the top staircase 21 is moved to the next tower segment 1A.
Can be lowered to the loading position, and thereafter, the above procedure can be repeated to perform the work of adding the steel tower 1.

Although the work of adding the tower 1 has been described above, when disassembling the tower 1, the carrier 2 is first lowered to the ground floor and removed, and then the power source is connected to the drive unit of the top connecting unit 10 (normal operation). At this time, the power source to the drive unit of the top gantry 10 is not connected) to retreat the gantry support pieces 18, 18 and release the holding of the gantry support pieces 18, 18 to the steel tower 1. Thereafter, the counterweight suspension wire rope 8 is removed by, for example, temporarily lowering the top connecting stand 10.

Next, the drive unit 12 of the top gantry 10 is operated to ascend to the top of the tower 1, the top gantry 10 is stopped at a position where one tower segment at the top can be removed, and the movable table 21 is moved to the tower. Advance to the holding position. After that, each support piece insertion hole 26 of both arms 24
The tower support piece 25a is inserted into the lower part of the horizontal member 1c on both sides of the tower segment 1A to be removed. During the operation of inserting the tower support piece 25a, the stop position of the top end stand 10 is determined so that the tower support piece 25a is located slightly below without contacting the horizontal member 1c of the tower segment 1A.

On both left and right sides of the tower 1, the tower support pieces 2
When 5a is inserted, the connecting bolt of the tower 1 is removed, and then the top connecting stand 10 is slightly raised so that each tower supporting piece 25a is brought into contact with the lower side of the horizontal member 1c on both sides of the tower, and the existing tower 1 is left as it is. Lifts the tower segment 1A. Therefore, if the moving table 21 is retracted in this state, the tower segment 1A is lifted up by the tower holding means 25 attached to the moving table 21 and is moved forward and away from the tower installation position while being lifted. Then, the steel tower segment 1A carried down on the ground part is lifted by a truck crane or the like to release the holding by the steel tower holding means 25 (withdrawing the steel tower supporting piece 25a), and the top end stand 10 is driven. The tower segment 1A is removed from above. Thereafter, by repeating this operation, the steel tower 1 can be sequentially dismantled and removed.

As described above, the operation of attaching / detaching the tower segment 1A to / from the existing tower is performed through the plurality of tower support pieces 25a on the arm 24 of the moving table 21 in the tower assembling / disassembling apparatus 20 on the top connecting stand 10. Since the tower segment 1A is held by being lifted upright, if the forward position of the moving table 21 is set by the stopper 13a so as to coincide with the position immediately above the existing steel tower 1, the moving table 21
And the vertical movement at the top of the tower of the top connecting stand 10 allows easy positioning and operation. In addition, since the landing 11 is provided with the landing 11 facing the front part and both sides of the tower 1, bolting and disassembling work of the tower 1 can be easily performed.

Next, another embodiment of the steel tower assembling / disassembling apparatus according to the present invention will be described with reference to FIGS. 7 and 8. FIG.

As shown in these figures, the tower assembling / disassembling apparatus 20A in this embodiment is mounted on the above-mentioned top end stand 10, and as described above, the required section of the tower and its front section are connected to each other. A movable platform 21A that can move between the movable platform, and both left and right frames (supports) 23 standing upright on the movable platform 21A.

The same parts as those in the above-described embodiment are denoted by the same reference numerals, and detailed description will be omitted.

The movable table 21A is positioned by a stopper (not shown) so that the tower segment 1A supported by the tower holding means 30 attached to the arm 24A at the most advanced position matches the existing tower installation position. The overall size is formed such that when it retreats backward, the tower segment 1A to be supported can be turned over.

The arm 24A attached to the frame 23A of the moving base 21A has its base end slidably engaged with a support seat 27 on the steel tower side of the frame 23A so as to be vertically slidable. It is connected movably up and down by a linear drive device 28 (for example, a hydraulic cylinder) provided between itself and the upper surface. In the middle of the upper part of these arms 24A, the bearings 3 are aligned on the same left and right axes.
1 are respectively attached. These bearings 31 are provided with support shafts (tower holding mechanisms) 32 each having a clamp 33 for gripping and fixing the horizontal member 1c of the tower 1 at the tip thereof. I have. It should be noted that, although not shown in place of the clamp 33 at the end of the support shaft 32, a support member including a face plate and a holding plate that can be fixed to the support shaft 32 by bolting with the steel tower horizontal member 1c or the like being used is used.

In addition to the tower holding means 30 comprising a support shaft 32 provided on the arm 24A and a clamp 33 (or a fixed holding by clamping a face plate and a holding plate), the arm 24A has a moving table 21A. It is preferable to provide a fixing means (not shown) such as a pad for temporarily fixing the tower segment 1A supported during the movement so as not to rotate.

The tower assembling / disassembling apparatus 2 thus constructed
For example, when the tower 1 is dismantled, the top tower 10 is operated independently to ascend the tower 1 and rises, and is fixed to the tower 1 at a predetermined position by the supporting pieces 18, 18 attached to the top tower 10. After that, the moving table 21A is moved forward to the steel tower side. Thereafter, the support shaft 32 of the tower holding means 30 attached to both arms 24A is advanced toward the tower, and the tower horizontal member 1c and the like are gripped and fixed by the clamp 33 at the tip. The positioning when the clamp 33 grips the horizontal member 1c of the steel tower 1 is performed by moving the arm 24A up and down by the driving device 28.

When the tower segment 1A to be dismantled is held by the tower holding means 30, the connected bolts are removed. After that, the drive unit 28 is operated to lift the tower segment 1A, and after separating from the existing tower 1, the moving table 21A is retracted, and if it is retracted to a position where it does not come into contact with the tower 1, the drive unit 28 is activated. The holding tower segment 1A is lowered to a stable posture, and the top connecting column 10 is lowered as it is to the ground portion. On the ground portion, when the movable base 21A is moved to the last retreat position, as shown in FIG. 7, the held steel tower segment 1A is pivotally displaced from the standing state to the horizontal state with the support shaft 32 as a fulcrum. In this way, on the ground portion, for example, a fork of a forklift is supported by being inserted into the frame of the tower segment 1A,
Tower horizontal member 1c by clamp 33 of tower holding means 30
When the holding operation is released, the forklift can be carried out of the top connecting stand 10 to the outside.

Thereafter, the tower 10 can be raised to the top of the tower, and the tower segments 1A can be sequentially disassembled and transported to the ground in the manner described above. In addition, the assembling of the tower 1 is performed in the reverse order of the dismantling operation described above.
A can be assembled by carrying A and sequentially adding it to the existing tower 1.

According to this specific example, the arm 24A attached to the movable base 21A mounted on the top connecting stand 10 and the tower holding means 30 are provided with a function of being moved up and down by the linear drive device 28. Therefore, the tower segment 1A can be assembled and dismantled without slightly moving the top connecting column 10 up and down at the top of the tower 1, so that there is an advantage that work at high places can be performed safely.

Note that the tower assembling / disassembling apparatus mounted on the top staircase in each of the above-mentioned embodiments does not cause any trouble in the mounted state during normal elevator operation.
