BACKGROUND OF THE INVENTION The present invention relates to a chimney lining repair device for repairing a deteriorated chimney lining.
Particularly, the present invention relates to a chimney inner wall working device suitable for repairing a lining of a large chimney.

[0002]

2. Description of the Related Art In order to repair a deteriorated chimney lining, a worker who is on a gondola moving up and down in the chimney by a winch installed on the ground carries out dismantling work of the lining. The gondola is suspended by a wire rope via a gondola arm installed at the top of the chimney, and stops at a target position in the chimney.
The worker in the gondola manually dismantles the deteriorated lining using a wheel cutter or air breaker at the stop position, and after this disassembly, the gondola moves to the next destination and stops. Then, the worker dismantles the deteriorated lining again. In this way, the deteriorated lining is removed, and the reinforcing work is performed. In this way, the deteriorated lining is removed, and after the completion, the lining is sucked.
If the lining deteriorates over the entire area of the chimney,
The above operation is performed over the entire area of the chimney.

[0003]

However, the conventional apparatus has the following problems. An operator cuts a slit with a wheel cutter at the boundary between a deteriorated lining and a sound lining that has not deteriorated, and then disassembles the deteriorated lining with an air breaker. When this air breaker is used, a large vibration is transmitted to the operator and a large noise is generated in the space inside the closed chimney.
This noise is difficult for the workers themselves to quench, and leaks to the periphery of the chimney, so that there is a problem that the noise increases around the chimney during the dismantling work.

[0004] On the other hand, the lining dismantled by the air breaker has a problem that the working environment is deteriorated because a large amount of dust is generated by scattering around the worker in various sizes and shapes. Further, the gas contained in the dismantled lining is also released, so that the environment inside the chimney is further deteriorated. An object of the present invention is to provide a chimney inner wall working device that can dismantle a degraded lining of a chimney inner wall and reduce generated noise without any person.

[0005]

The gist of the present invention to solve the above problems is as follows: 1) A plurality of extendable jacks are mounted on a base in a horizontal direction.
A fixed mounting frame is provided at the tip of the jack, and the fixed mounting frame
A movable mounting frame is mounted to move up and down freely, and a fixed mounting frame and movable mounting
A hydraulic cylinder for moving the hydraulic pad forward and backward
Set the jack horizontally and turn it on the base.
A work machine on the inner wall of the chimney on the turntable.
Chimney inner wall working device characterized in that it can be moved forward and backward in the direction of the chimney wall 2) A plurality of jacks that move forward and backward with a hydraulic cylinder on the base
Mount horizontally and attach a vertical frame to the end of the jack.
Axle angle can be changed for drive wheels above and below the vertical frame
To the chimney wall on the base.
A chimney inner wall working device characterized by being provided so as to be able to move back and forth in the direction 3) A chimney inner wall working machine provided on a base is dismantled
4) The chimney inner wall working device according to any one of 1) and 2) above, 4) a chimney inner wall working machine provided on a base is a liner.
The chimney inner wall working device according to any one of 1) and 2) above, wherein the device is a working device.

[0006]

According to the first aspect of the present invention, the pressing pad provided on the jack of the base and the lower mounting base is extended by a hydraulic cylinder and pressed to a predetermined position on the inner wall of the chimney, so that the working device for the inner wall of the chimney is fixed to the wall of the chimney. At the same time, the tip of the working machine on the inner wall of the chimney provided on the turntable is extended to the wall of the chimney and fixed at the working position. When the pressing pad of the jack provided on the lower mounting base is contracted by the hydraulic cylinder and the lower mounting base is raised to a predetermined position below the base, the pressing pad of the jack provided on the lower mounting base is extended and pressed against the chimney wall surface.

When the pressing pad of the jack provided on the lower mounting base is pressed against the inner wall of the chimney and the lower mounting base is fixed to the inner wall of the chimney, the pressing pad of the jack provided on the base shrinks, and When it rises and reaches a predetermined position, the pressing pad is extended and the base is pressed against the chimney inner wall. While repeating the above, raising and lowering the chimney inner wall working device, the working machine of the chimney inner wall fixed to the chimney wall works spirally along the inner periphery of the chimney inner wall while turning with a turntable, and the chimney inner wall Unattended work.

In the invention of claim 2, the jack provided on the base is extended by a hydraulic cylinder, and the pressing pads of the jacks provided on the fixed mounting frame and the movable mounting frame provided on the tip of the jack are pressed against the inner wall of the chimney. Then, the chimney inner wall working device is fixed to the chimney inner wall. At the same time, the tip of the working machine on the inner wall of the chimney provided on the turntable is extended to the wall of the chimney and fixed at the working position. The pressing pad of the jack provided on the movable mounting frame is shrunk, the pressure is released from the inner wall of the chimney, the movable mounting frame is raised to a predetermined position, and the pressing pad of the jack provided on the movable mounting frame is pressed against the inner wall of the chimney.

When the pressing pad of the jack provided on the movable mounting frame is pressed against the inner wall of the chimney, the pressing pad of the jack provided on the fixed mounting frame is contracted, and the pressure is released from the inner wall of the chimney to release the inner wall of the chimney simultaneously with the fixed mounting frame. The working device is raised to a predetermined position, and the pressing pad of the jack provided on the fixed mounting frame is pressed against the inner wall of the chimney. The working machine of the chimney inner wall fixed to the chimney wall at the same time as raising or lowering the chimney inner wall working device by repeating the above, works spirally along the inner periphery of the chimney inner wall while turning with the turntable, and the chimney Unattended work on the inner wall.

According to the third aspect of the present invention, the jack provided on the base is extended by a hydraulic cylinder, and the wheels of the vertical frame provided at the tip of the jack are pressed against the inner wall of the chimney.
At the same time, the tip of the working machine on the chimney inner wall provided on the base is extended and fixed to the working position on the chimney inner wall. By setting the axles of the wheels of the vertical frame fixed to the chimney inner wall at a predetermined angle and rotating the wheels all at once, the chimney inner wall working device moves up or down the chimney inner wall while rotating. At the same time, the working machine of the chimney inner wall provided on the base spirally moves up and down while rotating along the chimney inner wall, and performs the work of the chimney inner wall unattended.
