(Prior Art) The above-mentioned outrigger floats are becoming larger and heavier as cranes become larger. Such a heavy float is generally detachable from the outrigger jack cylinder, and is installed below the jack cylinder when the outrigger is in use, and is separated from the jack cylinder and stored separately when not in use. In this case, alignment between the two poses a problem, especially when installing the float below the jack cylinder, but conventional floats cannot be pulled by multiple people using ropes or machines such as forklifts. Since the position must be adjusted by horizontally sliding the ground, this alignment work is extremely troublesome and inefficient.

(Structure of the invention) The present invention is a float that is installed below the jack cylinder of an outrigger so that it can be attached to and detached from the jack cylinder, and on the upper surface of the ground plate.
A plurality of vertical ribs are provided in a radial arrangement centered at one point in a plan view, and a rod receiving portion is provided between the upper ends of each of these vertical ribs, with which the lower end of the rod of the above-mentioned jack cylinder engages, thereby forming the float body. At multiple locations around the float body,
The freely rotatable roller can be raised and lowered via a spring that supports the weight of the float body to a position that protrudes downward from the bottom of the ground plate and a position that retreats upward from the bottom of the ground plate against the spring. It is something that is established.

At four locations on the top surface of this float body 1,
Upper and lower brackets 6 and 7 extend outward from the vertical ribs 3 and the ground plate 2, and a cylinder 8 is vertically fixed to the tips of the brackets 6 and 7. A rod 10 is inserted into each of the four cylinders 8 via a compression coil spring 9 that supports the weight of the float body so as to be able to rise and fall. mounted rotatably around the shaft
A shaft 13 and a bearing 14 are attached to the bracket 12.
The rollers 15 are rotatably mounted around a horizontal axis via.

In this way, the four rolling wheels 15... can freely rotate around the vertical and horizontal axes in a caster manner, and in the no-load state, the bottom surface of the float body 1 ( The float body 1 is configured to protrude downward from the bottom surface of the ground plate 2 and touch the ground, and to move upward when a load exceeding the spring force is applied to the float body 1.

Note that the rod 10 has a threaded portion 10a at its upper portion, and the threaded portion 10a protrudes from the upper bracket 6.
By screwing nuts 16 and 17 onto a, the rod 10 is fixed so that it can only move upward from the above-mentioned no-load state where the wheels are in contact with the ground.

As mentioned above, in the no-load state, this float has four caster rollers 15 on the periphery touching the ground, and the float body 1 rises from the ground as shown in Figs. 2 and 3, so the outrigger In use, this float is installed below the rod 5a of the jack cylinder 5, and during centering work to accurately match the rod receiving part 4 to the position of the rod 5a,
The float can be easily horizontally moved with a slight force by the wheels 15. Therefore,
This centering work can be easily and quickly performed by one person.

After the above alignment, the jack cylinder 5
When the cylinder rod 5a is extended, the lower end of the cylinder rod 5a engages with the rod receiving portion 4, and the cylinder thrust causes the float body 1 to descend and touch the ground (the state shown in FIG. 4). At this time, while the wheels 15 are in contact with the ground, the spring 9 is compressed and the cylindrical body 8 is lowered, relative to the wheels 15.
5...and the rod 10 rises. Therefore,
Since no outrigger load is applied to the wheels 15 in this state, there is no risk that the wheels 15 and the rod 10 will be damaged by heavy loads. Furthermore, when the jack cylinder 5 is raised after using the outriggers, the float body 1 is raised by the restoring force of the spring 9.
The wheels 15 are relatively lowered to reach the grounding state shown in FIGS. 2 and 3. Therefore, the float can be easily removed from below the jack cylinder 5 by the caster action.

By the way, it is conceivable that the vertical ribs 3 are not provided on the upper surface of the grounding plate 2, and the rod receiving portions 4 are provided directly on the upper surface of the grounding plate, so that the outrigger main body 1 is formed into a flat plate shape. If this is done, the weight of the main body will be significantly reduced, making it easier to move the float, or eliminating the need to provide the wheels 15.

However, in this case, the total height of the float is reduced, and the necessary vertical stroke of the outriggers cannot be secured unless the length of the jet cylinder 5 is increased accordingly. Therefore, not only does the jack cylinder 5 become expensive, but also disadvantages arise, such as an increase in the amount of upward protrusion of the cylinder 5 from the outrigger box when the outriggers are in the retracted state.

一方、フロートが低くなつた分、ジヤツキシリ

On the other hand, if the installation position of the jack cylinder 5 is lowered to compensate for the lower float, there is no need to increase the length of the cylinder. Since the height of the cylinder is reduced, there is a risk that the lower end of the cylinder may come into contact with an obstacle on the road surface when the crane is traveling.

Therefore, in this float, vertical ribs 3 are provided on the upper surface of the ground plate 2, and a rod receiving portion 4 is provided between the upper ends of the vertical ribs 3.
The overall height of the float main body 1 is increased, and the vertical ribs 3 ensure main body strength sufficient to support the weight of the float. In other words, while maintaining the necessary height and strength of the float body 1, the problem of float movement caused by the increased weight of the float is solved by the wheels 15.

When transporting this float by placing it on the body of a crane or a truck, tighten the nuts 16 and 17 for each wheel 15 as shown by the imaginary line in FIG. By holding the float at a position above the bottom surface, unexpected movement of the float during transportation can be prevented.
Incidentally, it is also possible to carry out the above-mentioned tightening operation in a state in which the rolling wheels 15 are raised by the weight of the outriggers and the spring force is not acting on the nuts 16 and 17. Further, in order to facilitate the tightening operation of the nuts 16, 17, hand levers may be provided protruding from the nuts 16, 17.

ところで、転輪15…の設置個所数は上記した

By the way, the number of locations where the wheels 15 are installed is not limited to the four locations described above, and can be increased or decreased as appropriate.

(Effects of the invention) As described above, when using the float of the present invention, it is possible to easily move horizontally while in contact with the ground using the rolling wheels while maintaining the height and strength necessary for a float. Especially when using an outrigger, alignment work with a jack cylinder can be easily and efficiently performed.
