Description

  The present invention relates to a disassembly and transportation type pressure source unit, and more particularly to a disassembly and transportation type pressure source unit suitable for securing a pressure source in a remote place where transportation by a vehicle or the like is difficult.

As described in the prior art section of Patent Document 1, a steel tower for power transmission and communication is assembled by connecting a number of steel pipes to four tower legs. The outer peripheral surface of the steel tower is coated or coated with zinc to prevent corrosion. However, since steel towers are exposed to wind and rain, coatings formed by painting or galvanization are easy to peel off. There was a possibility that rust was generated at the peeled portion and the strength of the steel tower was lowered. In particular, the base of the tower base was close to the ground, and rust was easily generated.
Therefore, the steel tower is periodically repaired with a coating. At the time of repair, first, a blasting material such as metal powder, ceramic powder, and sand is sprayed onto the rust portion from a blasting apparatus. As a result, dirt, rust, remaining coating film and the like on the outer peripheral surface of the steel tower are removed. Next, paint is sprayed on the part from which rust has been removed or spraying of anticorrosive materials such as zinc and aluminum using a film forming device, and a part of the base treated with the blast material on the outer peripheral surface of the steel tower is coated with the film. cover.

The frame-like gantry 12 can be housed in the main body frame 15 in which the outer peripheral surfaces of the six cylinders 11 are in contact with both side surfaces three by three, and the inner space a of the main body frame 15 in an upside down state, and the main body frame 15 A head frame 16 that is detachably connected to the upper end surface of the head is an assembly type that is detachably connected by a bolt 17.
The main body frame 15 is a frame-like structure having a length of 90 cm, a height of 70 cm, and a depth (thickness) of 40 cm, and a pair of reinforcing frames 15b are provided between the lower ends of the vertical frames 15a constituting a part of both side surfaces. It is horizontal. On both the reinforcing frames 15b, six latch pins 30 of the three chains 13 for individually latching the three cylinders 11 are projected at a predetermined pitch. In addition, six similar latch pins 30 project from the upper frame 15c on both side surfaces of the main body frame 15 at a predetermined pitch. Inside the main body frame 15, an internal space a in which the head frame 16 can be stored is formed. Each latch pin 30 is disposed at the same corresponding position on one side surface and the other side surface of the main body frame 15.

The head frame 16 is a frame-like structure having a length of 75 cm, a height of 70 cm, and a depth (thickness) of 25 cm. The outer surface of the short frame 16a on the lower end side of the head frame 16 has a length extending over the entire length of the short frame 16a. Long brackets 18 with bolt holes formed at both ends in the direction are projected. Through both brackets 18, the head frame 16 is detachably provided on the upper surface of the main body frame 15 by two pairs of bolts 17.
Further, on the upper surface of the head frame 16, six neck valves 20 communicated with the gas discharge ports of the six cylinders 11 via the communication pipes 19, respectively, on both long frames 16 b constituting a part thereof, A gas discharge part 22 having a single annular gas collecting pipe 21 in which the neck valve 20 is arranged in the middle of the pipe is fixed. Specifically, each neck valve 20 protrudes at a predetermined pitch on both long frames 16b, and the flow path of the valve box of each neck valve 20 is communicated by an annular and horizontally long gas collecting pipe 21, and further the gas collecting pipe The pressure reducing valves 24 communicate with both end portions in the length direction of 21 via strainers 23. Both pressure reducing valves 24 are provided with a gas discharge nozzle 26 projecting from the end of the rubber hose (pipe) 25 (FIG. 4).

Next, with reference to FIGS. 1-4, the film repair work of the steel tower 14 of the mountainous remote area performed using the decomposition | disassembly conveyance type pressure source unit 10 which concerns on Example 1 is demonstrated.
When transporting the dismantling and transporting pressure source unit 10 to a mountainous area where the steel tower 14 is erected, first, the disassembling and transporting pressure source unit 10 is composed of six cylinders 11, a body frame 15, and a gas discharge unit. The head frame 16 with 22, six communication pipes 19, six chains 13, and two pressure reducing valves 24 are disassembled. Thereafter, the head frame 16 is turned upside down and stored in the internal space a of the main body frame 15, and the head frame 16 is fixed to the main body frame 15 in this state. Specifically, both brackets 18 are connected to both short frames 15 d constituting a part of the upper surface of the main body frame 15 by four bolts 17.
Thereafter, these members constituting the dismantling / transporting pressure source unit 10 are transported to a mountainous area, for example, by a carrier carrying or carrying the same. At this time, the frame-shaped gantry 12 is conveyed with the gas discharge part 22 facing downward. Since the frame-like gantry 12 is turned upside down on the head frame 16 including the gas discharge part 22 and is stored in the internal space a of the main body frame 15, the gas discharge part 22, particularly the neck valve 20, becomes an obstacle during transportation. The risk of collision and damage is reduced.

After transporting to a remote mountainous area, the disassembly and transport type pressure source unit 10 is assembled on site. Specifically, the head frame 16 is extracted from the internal space a of the main body frame 15, and the head frame 16 is fixed to the upper surface of the main body frame 15 with bolts 17. Next, six cylinders 11 are arranged in parallel on one side surface and the other side surface of the main body frame 15, and then a total of six chains 13 are latched on the respective latching pins 30 so that each cylinder 11 is hung on the main body frame 15. Thereafter, the gas discharge ports of the cylinders 11 and the neck valves 20 are communicated with each other through the six communication pipes 19.
Next, one end portion of the rubber hose 25 is communicated with the gas outlet nozzle 26 of one pressure reducing valve 24, and the other end portion of the rubber hose 25 is communicated with the gas pressure introducing portion of the blast treatment apparatus A. Further, one end portion of another rubber hose 25 is communicated with the gas outlet nozzle 26 of the other pressure reducing valve 24, and the other end portion of another rubber hose 25 is communicated with the gas pressure introducing portion of the thermal spraying apparatus (film forming apparatus) B. .

Thereafter, each neck valve 20 and one pressure reducing valve 24 are opened (the other pressure reducing valve 24 is closed), and nitrogen gas from each cylinder 11 gathered in the gas collecting pipe 21 is introduced into the blast treatment apparatus A. To do. Thereby, using the introduced gas pressure as a pressure source, the blast material is sprayed from the spray nozzle of the blast treatment apparatus A for a predetermined time toward the rust portion generated on the outer peripheral surface of the base of the tower base in the steel tower 14, Remove rust.
Next, one pressure reducing valve 24 is closed and the other pressure reducing valve 24 is opened, and nitrogen gas from each cylinder 11 is introduced into the thermal spraying apparatus B. Thereby, using nitrogen gas as a pressure source, aluminum is sprayed from the spray nozzle of the thermal spraying apparatus B to the portion where the rust of the tower base has been removed, and a part of the outer peripheral surface of the steel tower 14 that has been ground-treated with the blast material is made of aluminum. Coated. Since the dismantling and transporting pressure source unit 10 can be transported by human power, it can be transported to remote areas and used for coating repair work on the steel tower 14 standing on the site.

As described above, the disassembly and transportation type pressure source unit 10 includes the six cylinders 11, the main body frame 15, the head frame 16 with the gas discharge unit 22, the six communication pipes 19, and the six chains 13. Since it can be disassembled into two pressure reducing valves 24, the dismantling / transporting pressure source unit 10 can be transported manually to a site in a mountainous area. As a result, it is not necessary to secure a compressor installation base at a location apart from the site, which was essential in the past, and the long piping 25 for pumping high-pressure gas from the work base to the site is also unnecessary. It is possible to reduce the cost of repairing the coating including those required to secure the pressure source and to shorten the work time required to repair the coating.
Further, since the frame-shaped gantry 12 having an open wall surface is adopted as the gantry support frame, the weight of the gantry can be reduced. In addition, as the frame-shaped frame, a frame in which the main body frame and the head frame can be assembled and disassembled is adopted, so that the frame can be made compact during transportation.
Furthermore, since a large compressor is not used as in the prior art, noise during spraying is reduced, and construction in urban areas is also possible. In addition, a device for collecting dust is not required due to reduction of the gas pumping amount, and construction such as thermal spraying can be performed even in a narrow place.

  Further, since the height of the upper end surface of the head frame 16 after the assembly of the frame-shaped gantry 12 is set higher than the height of each cylinder 11, the six cylinders 11 are arranged in a confronting state in the middle of the frame-shaped gantry 12. Even when the frame-shaped gantry 12 is arranged on both sides, the operator can visually recognize the gas discharge port and the neck valve 20 of the cylinder 11 from the front, and the gas discharge port and the neck valve of the cylinder 11 by the communication pipe 19. The communication work with 20 can be easily performed. The reason why the six cylinders 11 are arranged in the middle of the frame-like gantry 12 is in a confronting state is that both sides of the dismantling / transporting pressure source unit 10 (left and right) ) For weight balance.

Moreover, the frame-like gantry 12 after assembling in this way is a large frame in which the height of the upper end surface of the head frame 16 is higher than that of the cylinder 11, and is not suitable for transportation by human power. Since 16 can be stored in the main body frame 15, the frame-like gantry 12 is made compact and can be transported.
Further, two or three or more disassembly and transportation type pressure source units 10 are used, and any one gas outlet nozzle 26 of each disassembly and transportation type pressure source unit 10 is communicated with each other by, for example, a one-touch connector. You may comprise so that it may increase.
