Description

[Detailed Description of the Invention] The present invention relates to a roller conveyor device with a lifter for testing rotating machines.

The rotating machine manufacturing process consists of a conveyor system that integrates assembly, testing, painting, and shipping, and after the various test items in the test process are performed on the conveyor, it is transported to the next painting process.

Traditionally, the rotating machine manufacturing process is connected by a roller conveyor 1 as shown in Figure 1, and consists of an integrated system that includes assembly, testing, painting, and shipping, and when each process is completed, it is sent to the next process. It looks like this.

When a rotating machine is tested using this roller conveyor 1, there is a risk that the rotating machine will move on the roller conveyor 1 and fall from the conveyor due to its vibration.
The necessary tests were not possible.

Furthermore, vibration tests on a roller conveyor cannot measure accurate vibration values due to the instability of the rotating machine support method.

At the same time, operating a rotary machine on a conveyor may cause damage to the bearing due to vibrations.

For the reasons mentioned above, especially in the case of large models, during the assembly process, the parts are transported by crane to a rigid test base, where necessary operational tests are performed, and then transported by crane again to the painting process. .

In this way, all rotating machines were transported using cranes, which caused inefficiency due to a lot of waiting time for the cranes.

The present invention was developed in view of the above-mentioned circumstances, and involves disposing rollers between the child surfaces of each screen of a test base whose top surface is shaped like a screen, and fixing these rollers to two parallel rails. A lifting device is provided on the rail of the housing octopus to raise and lower the roller, and the roller can be moved up and down from each gap on the screen surface of the base, and when the roller is lowered, the top of the base becomes a stable platform. To provide a roller conveyor device with a lifter which can be used as a roller conveyor when the rollers are raised so that assembly, testing, painting, and transportation of a rotating machine can be performed consistently.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 to 5.

FIGS. 2a and 2b are a plan view and a front view of the conveyor device according to the present invention. In the figures, 21 is a base whose upper surface is shaped like a cage, and 22 is a small surface of each cage of this base 21. There are rollers placed between them.

This roller 22 is supported at both ends by bearings 23a protruding from two parallel rails 23.

Further, the rail 23 is provided so as to be movable only in the vertical direction with respect to the base 21, and a plurality of short shafts 24 for raising and lowering the rail are provided on the side surface of the rail 23 and protrude horizontally at predetermined intervals. be.

Furthermore, a drive rail 25 is provided below the rail 23 in parallel with the rail 23 so as to be movable only in its axial direction.

On the drive rail 25, wedge-shaped drive operation pieces 25 are provided at positions corresponding to the shafts 24, and the shafts 24 are in contact with the slopes of the drive operation pieces 26. When the rail 25 is moved forward or backward, the shaft 24 is raised or lowered by the slope of the driving operation piece 26, and the roller 22 is protruded or retracted from each gap on the lower surface of the screen.

27 is a hydraulic jack for driving the drive rail 25 forward and backward, and 28 is a support roller that supports and guides the drive rail 25.

Next, the operation of this device having the above configuration will be explained.

In this apparatus, as shown in FIG. 3, a plurality of rotating machines 31 are placed on a base 21 at predetermined intervals, and a series of operations such as assembly, testing, and painting are performed.

At this time, as shown in FIG. 4, the hydraulic jack 27 is driven to drive the drive rail 25 in the direction of arrow A.

As a result, the drive operation piece 26 provided on the drive rail 25 is also moved in the same direction, so that the shaft 24 of the rail 23
is moved down the slope of the drive operation piece 26.

Therefore, the rail 23 is lowered, and the rollers 22 supported by bearings 23a protruding from the rail 23 are lowered below the plan view of each cage on the base 21.

Therefore, since the rotary machine 31 is placed directly on the pre-walled walls of each screen of the base 21, it is placed in an extremely stable state.

Therefore, various operations such as assembly, testing, painting, etc. can be performed extremely safely and reliably.

In particular, in a rotation test, even if rotational vibration occurs, there is no risk of the rotating machine 31 moving, which is different from when it is on a roller.

Next, in the case of transportation, a hydraulic jack 27 is used as shown in Figure 5.
is driven to move the drive rail 25 in the direction of arrow B.

Then, the drive operation piece 26 is also moved in the same direction as the drive rail 25 moves, so the rail 2 that is in contact with the slope
3. Push up the shaft 24 on the slope.

As a result, the rail 23 is raised, and the rollers 2 supported by the bearings 23a of the rail 23 are also raised, and the upper portions of the rollers 2 are projected from the gaps between the screens of the base 21.

Therefore, the rotary machine 31 of the base 21 has a protruding roller 22.
It will be placed on top and will become a roller conveyor, so
The rotating machine 31 can now be transported and moved.

In this way, each roller of the roller conveyor is arranged vertically movably in each gap between the screens of the base, whose upper surface is shaped like a screen, and the rollers are lowered during various operations such as assembly, testing, and painting. Place the rotary machine on the pre-walled screen of the stand, and
During transportation, the rollers were made to protrude upward into each gap between the screens of the screen to function as a roller conveyor, so this device was installed for each process of assembly, testing, and painting. By connecting it as a conveyor line, the rotating machine manufacturing process can be carried out consistently on the conveyor-in, including assembly, testing, painting, and shipping.Moreover, each process can be performed stably, so it is possible to carry out the manufacturing process of rotating machines consistently on the conveyor-in, making it possible to perform operations stably in each process. Transportation work using a crane is no longer required for each process, reducing time loss, and there is no need to worry about damage to the bearings of rotating machines or falling from the conveyor, which were caused by transportation using a crane. Reliability can be improved, and since the testing process is conveyor-based, sufficient testing can be carried out in a much smaller amount of space compared to conventional testing facilities. It is possible to provide a roller conveyor device with a lifter that has excellent features such as improved work efficiency.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications within the scope of the invention.
