Of course, it may also be in a suspended state. A driving means 4 for operating each of the above-mentioned components is mounted on the upper part of the support body 3. As the drive means 4, a generator 6, a hydraulic unit 7, a hydraulic pump 8, a drive motor 9, etc. are provided. Further, a pipe IO for sending a medium (oil liquid) for operating each of the above-mentioned components is suspended below the support body 3. Reference numeral 11 denotes a lifting wire so that the entire demolition apparatus 1 can be lifted up by a crane Z or the like. Surveillance cameras 12a, 12b, and 12c are provided on the crane side and inside the cylinder tower body, respectively, in order to monitor the cutting state of the cylinder tower body 2. These surveillance cameras 12a, 12
Images captured by units b and 12c are displayed on a monitor television T (see Figure 4) on the ground using wireless signals, so that each component of the demolition equipment l can be controlled from the ground. A tube tower body cutting device main body 5 is suspended from the lower part of the support main body 3 by a wire 13. This tower body cutting device main body 5 has a size that can be inserted into the chimney X to be dismantled, and is equipped with each component for cutting the tower body 2 as described above. That is, at the lower end of the barrel-tower body cutting device main body 5, telescopic arms 14 are disposed on the left and right sides in the horizontal direction.
4 is designed to be expanded and contracted by an internally installed hydraulic cylinder 14a. Rod 14b of this hydraulic cylinder 14a
Two roller bits 15, which are cutting blades for cutting firebrick a, and one disc cutter 16, which is a cutting blade for cutting steel pipes, are rotatably attached to the tip. The disc cutter 16 projects slightly outward from the roller bit 15, and the difference therebetween is set to be equal to or slightly larger than the wall thickness of the steel pipe to be cut. In addition, the hydraulic cylinder 14a is operated so that the rod 14
In order to expand and contract the pipe 10. It is also delivered to each hydraulic cylinder 14a through a central through hole 19 of a rotating shaft 18 connected via a swivel 17. Further, both of the telescopic arms 14 are connected to the cylinder tower body cutting device main body 5.
It is configured to rotate via the rotation shaft 18 by a hydraulic motor 20 disposed in the. 21 is each hydraulic motor 20
This is a gear fitted to the shaft 20a of the rotary shaft 18, and meshes with a large gear 22 fitted to the rotating shaft 18. The rotation shaft 18 is rotatably supported by a bearing 23 in the vertical direction. As shown in FIG. 2, reference numeral 24 denotes support means operated by the drive means 4 to hold the cut portion of the cylinder tower body 2a from the inside. This support means 24 is connected to the cylinder tower body cutting device main body 5.
A plurality of them are arranged at two locations: at the upper end (see FIG. 1) and at the lower end of the main body 5 of the barrel-tower body cutting device, slightly above the telescopic arm 14. Each support means 24 consists of a boomerang-shaped rotational reaction force receiving plate 25 and an operating cylinder 26, and one end of the rotational reaction force receiving plate 25 is provided protruding from the outer periphery of the supporting plate 27 and is rotatable on a support piece portion 28. It is pivoted to. Further, the operating cylinder 26 is mounted on a support plate 27, and the tip of a rod 29 is connected to the vicinity of the pivoting portion of the rotational reaction force receiving plate 25. The actuating cylinder 26 is actuated by the action of the driving means, and the rod 29 protrudes, so that the rotational reaction force receiving plate 25 rotates around the pivoted portion as a fulcrum, and the rotational reaction force receiving plate 25 is activated by the refractory brick a of the chimney X. The cylindrical tower body 2 of the cut part cut into the
a and is fixed to the cylinder tower body 2a so that the cylinder tower body cutting device main body 5 does not rotate. The above-mentioned dismantling equipment 1 is located in a control room 30 on the ground (see Fig. 4).
The above-mentioned surveillance cameras 12a, 1
Monitor TV T for images sent from 2b and 12c
The cutting situation of the chimney X can be grasped while looking at the chimney X, and each component of the demolition equipment I can be operated by remote control by radio to cut the chimney X. The operation of the crane Z that suspends the demolition equipment 1 and the cut tower body 2a is as follows:
It is operated by the worker aboard the crane Z while communicating between the worker aboard the crane Z and the worker monitoring the cutting state on a monitor TV T on the ground. In order to dismantle the chimney X that is no longer needed using the demolition device l constructed as described above, first, the demolition device l is lifted up by the wire 13 using a crane, and the cylindrical tower body equipped with each component is placed in the upper opening Y of the chimney X. The cutting device main body 5 is inserted, and the support main body 3 is placed on the upper end of the chimney X. Next, each actuating cylinder 26, which is the supporting means 22, is operated by the action of the generator 6, the hydraulic uni-soto 7, the hydraulic pump 8, etc., which are the driving means 4, and the rod 29 is protruded, and the rotational reaction force receiving plate 25 is activated. The cylindrical tower body cutting device main body 5 is fixed in the chimney X by being fitted into the refractory brick a attached to the inner surface of the chimney. Next, the hydraulic motor 20 is rotated by the action of the driving means 4, and the telescopic arm 14 is rotated via the gear 21, the large gear 22, and the rotation shaft 18, and the cylinder 14a installed inside the telescopic arm 14 is actuated. Then, the rod 14b is made to protrude in the horizontal direction, and the refractory brick b is scraped off using a roller bit 15 rotatably provided at the tip of the rod 14b, and the steel pipe is cut using a disc cutter 16. The cutting state of the above-mentioned steel pipe is observed on the monitor TV T via the surveillance camera 12, and when the cutting is completed, the rotation of the telescopic arm 14 equipped with the roller bit 15 and the disc cutter 16 is stopped by wireless operation, and the telescopic arm 14 is
The rod 14b of is contracted. The rotational reaction force receiving plate 25 remains wedged into the refractory brick b of the cut cylindrical tower body 2a. After doing this, the demolition device 1 is lifted up again by a crane, and the cut tower body 2a is lowered to the ground. By repeating these operations one after another, the high-rise chimney X is cut and dismantled. In addition, FIG. 5 shows another embodiment according to the present invention, and in this embodiment, the support means for supporting the chimney portion 2a to be cut is a gripper cylinder 31 and a mandrel type stabilizer 32.
Below the mandrel type stabilizer 32 is a disc cutter 33 for cutting the steel pipe of the chimney.
is arranged, further below this disc cutter 33,
A roller bit 34 is provided to remove the refractory brick a prior to cutting of the steel pipe by the disc cutter 33. 34 is a hydraulic pressure generating device that operates the gripper cylinder 31, mandrel type stabilizer 32, disc cutter 33, and roller bit 34. In this embodiment, the surveillance camera 12 is provided on the crane Z side and also on the cutting section side (not shown).
