Description

[Detailed Description of the Invention] The present invention relates to a gondola device for a smoke stack chimney.

Figure 1 shows the lining construction work and lining repair work for a conventional chimney with a smoke collection structure, in which a gondola suspension support beam 3 is inserted into a manhole 2 provided in a chimney barrel 1, and the gondola suspension support beam 3 is attached to the beam 3. The gondola 6 is moved by the pulley 4 and the lifting cable 5 that spans the pulley 4.
The gondola 6 is lifted and lowered to carry out the required work by suspending and supporting the hoisting cable 5 and winding it back up by a hoisting machine on the ground. Work inside the smoke collecting section where the gondola 6 cannot be raised or lowered is carried out by constructing a scaffold 8 from the top 7. There is also a method of constructing the smoke collecting section with a double pipe lining made of stainless steel without spray lining, but this method has the disadvantage of high cost.

The conventional lining construction and repair work described above requires scaffolding work at dangerous heights, which reduces work efficiency, and also requires large scaffolding equipment to be brought in from the ground each time during construction, repair, and inspection. The number of man-hours increased because the choreography was choreographed using the same technique, and it was also necessary to install a manhole for the gondola suspension support beams and install the suspension support beams.
This method had the disadvantage that materials and man-hours were increased.

The present invention was proposed in order to eliminate such drawbacks, and includes a gondola hanging support that is removably supported by a support member installed on the outer circumferential surface of the top of a smoke collection structure chimney, and extends from the top opening of the chimney. A fixed pulley is attached to a beam for use, and one end is connected to the beam,
and a gondola device for a smoke-collecting structure chimney, characterized in that the other end of the gondola lifting cable that suspends and supports the gondola inside the chimney is connected to a hoisting device on the ground part via the fixed pulley. It is.

In the present invention, as described above, a gondola suspension support beam equipped with a fixed pulley extending from the chimney top opening is removably attached to the support member disposed on the outer peripheral surface of the top of the smoke collection structure chimney. The gondola is raised and lowered within the barrel via a gondola lifting cable that spans a pulley, has one end connected to the beam, and the other end connected to a hoisting device on the ground. By suspending the gondola from the top of the cylinder, it is possible to eliminate the need for scaffolding at high places, improving safety and work efficiency, and eliminating the need for conventional large gondola suspension support beams and manholes. Therefore, it is possible to reduce the number of man-hours and cost, and furthermore, it is possible to reduce the cost by reducing the portion where the stainless steel double tube lining is applied.
Furthermore, according to the present invention, the beam is removably supported by the support member on the outer peripheral surface of the top of the cylinder, so the present invention has many advantages, such as easy installation and removal of the gondola device. .

The present invention will be described below with reference to the illustrated embodiments.

2 to 6 show a first embodiment of the present invention, in which 10 is a gondola fixed to the top part 11a of the top part 11 of the smoke collecting structure chimney so as to project to the upper end opening of the top part 11. The suspension support beam is fixed to a mounting member 13 fixed to the outer circumferential surface of the cylinder body 11 via a vertical support member 12 hanging from the base end thereof.

A fixed pulley 14 is attached to the gondola suspension support beam 10, and one end is connected to the beam 1 through an eye plate 15.
A gondola lifting cable 16 connected to the gondola 17 is spanned over the suspension support pulley 18 of the gondola 17 and the fixed pulley 14, and is wound around a winch on the ground.

Since the illustrated embodiment is constructed as described above, the gondola 17 is raised and lowered within the barrel 11 by winding and unwinding the lifting cable 16 using a winch.

Note that when the gondola is not in use, the beam 10 and auxiliary equipment are removed from the barrel 11, and this embodiment has a simple configuration and is easy to install and remove.

7 to 9 show a second embodiment of the present invention, in which the gondola suspension support beam 10 is formed longer than in the first embodiment to support the gondola on which the fixed pulley 14 is mounted. The point protrudes from the top 11a of the cylinder 11 toward the center of the cylinder, and the base of the beam 10 is fixed to a mounting member 19 fixed to the outer circumferential surface of the top of the cylinder 11, and attached to the bottom of the plate 19. Attachment member 20 fixed to barrel 11 at
The diagonal member 21 is fixed to the main body of the main body through diagonal members 21. In the figure, reference numeral 14' denotes a fixed pulley attached to the beam 10, and other parts equivalent to those in the embodiment described above are given the same reference numerals.

By protruding the gondola support point of the gondola suspension support beam 10 into the inside of the barrel, the gondola 17 can be lifted higher, which increases the possible range of castable lining construction. Therefore, the number of parts to be lined with stainless steel double tubes is reduced, and costs are reduced.

10 and 11 show a third embodiment of the present invention, in which the gondola suspension support beam 10 is composed of a T-shaped beam formed by combining a horizontal beam 10A and a cross beam 10B, and this is attached to the top of the barrel 11. It is supported in three places, with the center of the cross beam 10B and the horizontal beam 1 on the beam.
Fixed pulleys 14, 14″ at two locations with the base end of 0A
is mounted. In the figure, 22 indicates each beam 10A,
10B is a mounting member. Other parts in the drawings that are equivalent to those of the above embodiments are given the same reference numerals.

In this embodiment, as in the second embodiment, the gondola support point of the gondola suspension support beam 10 protrudes into the inside of the barrel, so the gondola 17 can be lifted high, and the possible range of castable lining construction is increased. This reduces the number of parts to be lined with stainless steel double tubes and reduces costs.

12 to 14 show a fourth embodiment of the present invention, in which a pair of upper and lower eye plates 23, 23' are attached to the outer peripheral surface of the barrel 11, and a gondola suspension support beam 10 is attached to the lower eye plate 23. A vertical support member 24, which hangs vertically from the base end of the eye plate 24, is pivotally attached so as to be able to rise and fall freely, and the member 24 is detachably connected to the upper eye plate 23. Fixed pulleys 14, 14 are attached to the beam 10 at its tip and base ends.

When suspending the gondola 17, the vertical support member 24 is raised as shown by the dotted line in FIG. Then, one end of the gondola lifting cable 16 is connected to the eye plate 15 of the beam 10, and the lifting cable 16 is connected to the gondola 1.
7 and the pulleys 14 and 14'', and is wound around a winch on the ground.

The gondola 17 is raised and lowered by winding and returning the gondola lifting cable 16 by operating a winch.

When storing the illustrated device, remove the lifting cable 16 and the gondola 17, and remove the eye plate 2.
3 is removed, the vertical support member 24 is rotated, and the platform is lowered onto the storage box 25 of the platform.

According to the illustrated embodiment, by storing the gondola suspension device, there is no need to bring in a new gondola suspension device during lining repair work, reducing the number of man-hours and construction period. It can also be used for loading cargo, and it also eliminates unsafe work such as disassembly and installation.
