Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a large fixed roof type tanker and transport device.

A large safety valve is installed at the top of the roof of the large fixed roof tank.
A main valve etc. is provided. These safety valves need to be inspected periodically, but conventionally, crane work is difficult due to the presence of a dike, so temporary scaffolding is built on the roof and removed manually, and in some cases, they are transported to the ground and inspected again. It was transported from the tank shoulder to the top of the tank. Therefore, the work was laborious, it was necessary to obtain the material in large numbers, and it was dangerous.

In addition, in the past, aluminum materials were used to reduce the weight of safety valves, etc. (for example, 9 out of 100), but the safety standards for safety valves, etc. are so strict that it is no longer possible to use all real aluminum materials. The weight of safety valves, etc. has also increased by about three times (for example, 300 times 9), making it almost impossible to transport them manually as before.

The present invention was developed in view of the above-mentioned conventional situation, and the heavy objects can be transported by a small number of people by running the heavy objects along a rail laid from near the top of the tank roof to the tank shoulder. This involves a transportation device on the tank roof that can be carried out in a short time and safely.

Embodiments of the present invention will be described below with reference to the drawings.

Figures 1 and 2 show an embodiment of the present invention, in which two rails (2) are laid horizontally from the top of the tank roof (1) to the shoulders, and a trolley is equipped with wheels (3). (4) is placed on the front rail (2) so that it can run, and a rope of a winch (not shown) provided at the top of the tank roof (1) is connected to the truck (4), and the truck (4) This makes it possible to prevent towing regression and runaway. Further, a tower davit (5)' is disposed near the shoulder of the tank roof (1) of the rail (2).

In the figure, (6) is baggage.

When inspecting or replacing the valve at the top of the tank roof (1), remove the valve, place it on the trolley (4), unwind the rope with a winch, and move the trolley (4) from the top to the shoulder on the rail. (2) Run on top of the rail. Next, transfer the cargo (6) such as valves placed on the trolley (4) to the tower davit (5), and change the direction of the tower davit (5) to the rail (5). 2) From the side toward the outer periphery/side of the tank side wall, use a winch on the ground to lower cargo (6) onto the ground J:1.Here, lower cargo (d) such as valves, etc.
When the trolley (4) on which is mounted is run (lowered) along the rail (2), the operator may use the inclination of the rail (2) to run while braking.

Next, the baggage (6) such as the valve that was inspected or replaced on the ground is again transported and attached to the top of the tank roof (1) by reversing the removal procedure described above. Here, the carriage (4) carrying the cargo (6) is moved (raised) by winding a rope with a winch.

FIG. 3 shows another embodiment of the present invention, in which the tank roof (1)
Two rails (2) are laid parallel to the roof staircase (7), which is permanently installed from the top to the shoulder of the roof staircase (7).
This is an example in which the cart (4) can run between the handrails (8) of the The other configurations are the same as those of the previous embodiment.

In the case of this embodiment as well, the cargo (6) such as a valve can be transported in the same manner as in the previous embodiment, and in particular, the equipment cost can be reduced because existing equipment can be used.

In the above embodiment, there is no need to permanently install the truck (4) and the winch, rope, etc. for running the truck (4).
When inspecting or replacing valves, etc., it may be temporarily transported and placed on the tank roof (1).

It should be noted that the carrying bag W (d) on the tank roof of the present invention is not limited to the above-mentioned embodiment, and it is of course possible to make various changes without changing the spirit of the present invention. .

As described above, according to the transport equipment on the tank roof of the present invention, the cargo can be transported along the rails that are laid from the top of the tank roof to the shoulders, making it possible to transport heavy objects in small numbers. It can be performed safely by personnel in a short period of time, and exhibits various excellent effects.

[Brief explanation of the drawing]

FIG. 1 is a diagram showing a state in which rails are laid in the present invention, FIG. 2 is a first explanation of one embodiment of the present invention, and FIG. 6 is an explanatory diagram of another embodiment of the present invention. In the diagram, (1) shows the tank roof, (2) shows the rail, (3) shows the wheels, (4) shows the trolley, (5) shows the tower dahit, (7) shows the roof stairs, and (8) shows the handrail. .

Claims (1)

[Claims] 1) A rail laid from the top of the tank roof to the shoulder, a bogie that runs along the rail, a winch for running the bogie, and a rail installed on the shoulder of the tank roof and near the end of the rail. A transport device on a tank roof, comprising a tower davit.
