Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a jib crane device, and in particular, to expand the operable area of the device, reduce the number of necessary devices, and make effective use of space. It also relates to something that aims to shorten the working time.

(Prior Art) Overhead cranes and jib cranes have been used to disassemble, assemble, move, or lay down relatively small equipment. That is, a jib crane is placed outside the movable range of the overhead crane, and the above-mentioned operations are performed by a combination of the overhead crane and the jib crane.

The above configuration has the following problems.

■First of all, in the case of an overhead crane, the work requires 111 hours,
Therefore, there was a problem in that the operating rate of the plant decreased.

■Next is the jib crane. This jib crane is fixed to a wall or pillar, so the range of movement of one jib crane is narrow and limited, and therefore multiple jib cranes are required. There was a problem from the viewpoint of effective use of the limited space.

(Problems to be solved by the invention) In this way, with the conventional configuration, the work takes a long time and reduces the IS rate of the plant, and also requires multiple jib cranes, making it difficult to There are problems in attempting to simplify and reduce costs, and the present invention has been made based on these points, and its purpose is to reduce the number of units required by making them multipurpose and common. It is an object of the present invention to provide a jib crane device capable of reducing the amount of space required for effective use of space, shortening the time required for work, and improving the operating rate of a plant.

[Structure of the Invention] (Means for Solving the Problems) That is, the jib crane device according to the present invention has a first track laid along the wall of a building, and a jib crane device that runs along the first track and moves inside the building. a crane main body that moves to a desired position; a second track that is attached to the crane main body and is rotatable in a horizontal plane around the part; It is characterized by being equipped with a hoist mechanism that can travel along a track.

(Operation) In other words, a first track is laid along the wall of the building, and this
The crane main body travels along a track, and a second track is attached to the crane main body so as to be rotatable about the mounting number part. A hoist mechanism is attached to this second track, and this hoist mechanism is movable along the second track.

(Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a plan view showing the configuration of the jib crane device according to this embodiment. In the figure, reference numeral 1 is the wall of the building, reference numeral 2 is a plurality of pillars provided at equal intervals, and reference numeral 3 is the floor. It is. As shown in FIG. 2, a moving rail bracket 4 is attached to the pillar 2 at a predetermined height position. A moving rail 5 is laid on these moving rail brackets 4.

On the other hand, another moving rail 6 is also installed on the pillar 2 above the moving rail 5. A column 7 for mounting the jib crane travels via these pair of moving rails 5 and 6. That is, in this jib crane installation, a bracket 8 is attached to the lower end of the pillar 7, and this bracket 8
A plurality of traveling wheels 9 (only one is shown in the figure) are rotatably attached to the. The traveling wheels 9 are rotated by a drive i mechanism (not shown) to travel on the moving rails 5. On the other hand, when installing a jib crane, another bracket 10 is attached to the upper rear side of the pillar 7, and this bracket 10
is engaged with the moving rail 6 and functions as a guide during traveling.

The above jib crane is installed on the front side of the pillar 7 and has two upper and lower parts.
Bracket receivers 11 and 12 are attached to the locations, respectively. Brackets 13 and 14 are attached to the bracket receivers 11 and 12, respectively. An I-beam 15 is attached to the bracket 14, and a support member 16 is attached to the bracket 13. The tip of the support member 16 is connected to the tip of the I-beam 15 . The beam 15 is rotatable in a horizontal plane about the bracket 14 as a fulcrum, as shown by the arc in FIG.

A hoist 17 is attached to the I-beam 15, and the hoist 17 runs along the I-beam 15.

Further, a hook 18 is attached to the hoist 17, and a medical instrument or the like is held via this hook 18. In FIG. 1, numeral 18 is a hatch, and numeral 19 is a decontamination pan.

The operation will be explained based on the above configuration. The jib crane of this embodiment can travel inside the building along the moving rails 5 and 6, and the I-beam 15 rotates about the bracket 14 as a fulcrum. And hoist 17 is I beam 1
Drive along 5. In other words, the structure is such that only one jib crane can cover the entire building interior. To explain an example of the work, a device (not shown) to be decontaminated is lifted and placed on the decontamination pan 19. Next, the equipment that has been decontaminated is lifted up again and moved to a location away from one of the decontamination pans. Next, when disassembling or assembling equipment on the hatch 18, move the jib crane to the moving rail 5.
and 6 to near the hatch 18 (indicated by the dotted chain line in FIG. 1). Conventionally, in such cases, hatch 1
It was necessary to place another jib crane near No. 8. In this embodiment, the jib crane can be moved along the moving rails 5 and 6 to a desired position. After moving it to the vicinity of hatch 18, hatch 18
The equipment inside is lifted up and placed on the floor 3 for disassembly work. If the jib crane is to be used at another location, the jib crane may be similarly moved along the moving rails 5 and 6 to the desired location.

According to this embodiment, the following effects can be achieved.

■First of all, only one jib crane is required, whereas in the past multiple units were required. That is, the jib crane can be moved along the moving rails 5 and 6 to a desired position within the building, and therefore the entire building can be covered by one jib crane. Therefore, the configuration is greatly simplified and the limited space inside the building can be used effectively.

It is also possible to reduce costs.

■Next, since the jib crane can be moved within the building to a desired position, some of the work that was conventionally done with an overhead crane can be done with the jib crane. Therefore, it becomes possible to use the overhead crane and the jib crane simultaneously, and the time required for the work can be significantly reduced. This is extremely effective in improving plant availability.

■Furthermore, in the case of the real example, there are two moving rails 5.
and 6 are arranged to support the crane via brackets 8 and 10, respectively, so that stable traveling can be provided. Furthermore, since the load is supported by the moving rail bracket 4, it is structurally stable.

Next, a second embodiment will be described with reference to FIGS. 4 and 5. In this embodiment, the moving rail bracket 4 in the first embodiment is arranged above the moving rail 6, and the moving rail 5 is laid on the lower surface of this bracket 4. Although it is not shown in the drawing, it will run in a mole rail style. The other configurations are the same as those of the first embodiment. The second embodiment can also provide the same effects as the first embodiment.

Next, a third embodiment will be described with reference to FIGS. 6 and 7. This third embodiment has the structure of the first embodiment, but the moving rail 6 is also attached to the pillar 2 via the moving rail bracket 4. The rest of the structure is the same as that of the first embodiment, and the same effects as those of the first embodiment can be obtained.

Next, a fourth embodiment will be described with reference to FIGS. 8 and 9. In this fourth embodiment, the moving rail 5 is also attached to the wall 2 in the first embodiment. In this case as well, although not shown in the drawings, the vehicle is driven by running wheels and a drive mechanism. The rest of the structure is the same as that of the first embodiment, and therefore the same effects as those of the first embodiment can be achieved.

It should be noted that the present invention is not limited to the first to fourth embodiments described above, and various configurations can be considered, for example, regarding the method of mounting the moving rail or the configuration of the traveling section.

[Effects of the Invention] As detailed above, according to the jib crane device according to the present invention, the operable range of the device itself is greatly expanded, the number of required devices is greatly reduced, and space can be used effectively. In addition to this, the time required for the work is significantly shortened, making it extremely effective in improving plant operation rates.
