Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a crane movement method for lifting a crane fixedly attached to a freight car and moving it to another freight car.

<Conventional technology> In recent years, with the development of transportation means, most railways have changed from diesel locomotives to electric trains, but in order to run trains, electric wires to supply electricity and utility poles to attach them are required. It becomes necessary. Conventionally, as shown in Fig. 8, for example, the method of transporting these utility poles is to attach and fix a crane 1 to a - freight car A, load a large amount of utility poles A onto another freight car, and pull them with a diesel locomotive P. I was going by that. When you arrive at the designated location, crane 1
The utility poles A are lowered one after another at predetermined intervals, and when all of the utility poles A are finally removed, the utility poles A are returned to the original location where they were loaded, and the utility poles A are loaded again by 1 u and transported again. By repeating the process several times, a large number of utility poles were transported.

In addition, as another transportation method, as shown in Figure 9, electric poles A and B
A freight car with crane 1 attached and fixed is placed between freight cars a and c loaded with utility poles, and behind it is placed a freight car with crane 1 attached and fixed between freight cars d and ``, which are loaded with utility poles C and D. A large number of freight cars were connected to each other so as to be placed in the same position, and the trains were transported by being pulled by a locomotive P.When they arrived at a predetermined location, a crane 1 was used to move utility poles A and B of freight cars a and (on both sides) at a predetermined distance. When the utility poles A and B on both sides are all gone, the utility poles C and D from the other freight cars d and f are lowered to their designated locations by the crane attached and fixed to the freight car e. Ta.

<Problems to be solved by the invention> However, in the former method, after all utility poles A are lowered to the ground, the utility poles A must be returned to the loading location, loaded onto the freight car a again, and transported. However, in order to transport a large number of utility poles, it is necessary to make multiple trips back and forth, which poses problems such as a great deal of labor and effort.

In addition, the latter method requires a large number of cranes, which requires a lot of time and effort to attach and secure them to the freight car, and also requires the use of a single crane at the location where the utility pole is to be lowered. Since no other cranes are used while the vehicle is in use, many cranes are wasted.
There were problems such as a decrease in the amount of 3i.

The crane moving method according to the present invention aims to solve these problems. The process of releasing the crane attached and fixed to the crane, the process of extending the four arms installed on the crane horizontally in the width direction of the freight car, and the process of extending the legs connected to each of the cough arms downward. It consists of a step of raising the legs, a step of further extending the legs to lift the crane, and a step of moving the freight car below the crane.

According to the above means, the crane can be unattached, the four arms can be extended outward beyond the width of the freight car, and the legs connected to the arms can be erected. Furthermore, by extending the legs, the crane can be lifted, and the crane can be moved from one freight car to another.

<Example> Next, an example to which the above means is applied will be described with reference to the drawings.

Figure 1 is a schematic diagram of the movement of utility poles, Figures 2 and 3 are illustrations of crane movement, Figure 4 is an illustration of crane fixation, Figure 5 is an illustration of crane lifting, and Figures 6 and 3 are illustrations of crane movement. FIG. 7 is an explanatory diagram of the contraction of the arms and legs.

In the figure, a, b, c... old... are freight cars that are connected together to form a train, and a crane 1 is mounted on top of the leading freight car a by a specific fixing device (not shown). It is installed and fixed, and below the freight car on the second side are utility poles A, B, C...
...... are loaded respectively.

Furthermore, four arm parts 2 that can freely expand and contract in the width direction of the freight car a are integrally attached to the four sides of the lower part of the crane 1,
Legs 3 that can freely expand and contract in the vertical direction to lift up the crane 1 are connected to the tips of the arms 2, respectively. configured to control. Also, at the lower ends of the four leg parts 3, there is a bottom plate 3a that stabilizes the legs when standing on the ground.
is installed.

Note that P is a diesel locomotive for pulling freight cars.

Next, to explain how to use and move the crane 1, first, when you arrive at the place where the utility pole A is to be lowered, as shown in Figure 4,
While extending the arm 2 of the book in the width direction of the freight car a,
Extend outward beyond the width of the

Next, the legs 3 connected to the arms 2 are extended downward, the bottom plate 3a is fixed to the ground, and the legs 3 are fixed in an upright position, thereby further stabilizing the operation of the crane 1.

Next, the crane 1 lowers a predetermined number of utility poles A on the freight car at predetermined intervals, and when all the utility poles A on the freight car are finally removed, the crane 1 is unattached from the freight car a and the legs are lowered as shown in Figure 5. The part 3 is further extended downward, and the crane 1 is lifted above the freight car a via the arm part 2. In this state, the locomotive P is run in the direction of the arrow X as shown in FIG. By placing the crane 1 on the freight car, the crane 1 can be moved from the freight car a to the freight car A.

Thereafter, the crane 1 is attached and fixed to the freight car using a fixing device.

Then, as shown in FIG. 6, the legs 3 are contracted and
The train is rotated by .degree. C. so as to be parallel to the upper surface of the freight car, the arms 2 are contracted as shown in FIG. 7, and the train is driven to the next location.

Next, when arriving at the designated location, the utility pole B of the freight car C is lowered, and if the utility pole B of the freight car C is no longer present,
If the crane 1 is mounted and fixed on top of the freight car C in the same manner as described above, the telephone pole C of the freight car d can be lowered.

By repeating the above operations, utility poles loaded on a large number of freight cars can be sequentially lowered to predetermined locations using one crane 1.

In the above-mentioned embodiment, in order to lower a predetermined number of utility poles at once, the legs 3 are fixed in an upright position to stabilize the operation of the crane 1. If the weight is light, the legs 3 do not need to be fixed in an upright position.

Furthermore, in the above-described embodiments, utility poles were used as an example of the load on a freight car, but it goes without saying that the above-described method can also be applied to transporting railroad ties, rails, and the like.

<Effects of the Invention> The crane moving method according to the present invention is as follows:1. In addition to releasing the crane attached to the freight car, the four wooden arms on which the crane is attached can be extended beyond the width of the freight car, and the legs connected to each arm can be erected. Furthermore, the crane can be lifted by extending its legs and moved from one freight car to another, so it is only necessary to mount and fix one crane on a freight train, thus requiring less effort. This has the advantage of not only eliminating the need for cranes, but also making it possible to load utility poles and the like onto all other freight cars, making it possible to load a large amount of cargo.
