BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a mounting jig of a small column mounting crane according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a column of a frame or the like which is not strong enough to mount a small crane and suspend a load, 2 denotes a small crane, 3 denotes a small crane 2 and a crane support for supporting the weight of a suspended load, and 4 denotes a small crane 2 The control panel 5 is a rigid body for controlling the driving of the crane. The crane supports 3 are formed by joining the required number, and the control panel 4 is fixed to the crane supports 3. A crane pedestal 5 is mounted on the crane support 3 to support the small crane 2.
The mounting jig of the small crane is composed of an upper support portion and a lower support portion, each of which has a contact plate member 6 interposed between the column 1 and the crane support column 3, a pin fixing member 7 integrated with the contact plate member 6, and a jack. 8, a jack holding plate member 9, a jack plate member 10, a belt (steel strip) 11 connecting the pin fixing member 7 and the jack 8 interposed between the pillar 1 and the jack 8, and the pad plate member 6 are integrated. The lower connecting member 12 is composed of an upper connecting member 13 integrated with the crane support 3.
[0007]
2A and 2B show a lower support portion of the small crane mounting jig, FIG. 2A is a cross-sectional view as viewed from AA in FIG. 1, FIG. 2B is a side view of FIG. FIG. 3 is an enlarged view of the pin fixing member 7 of FIG.
The lower connecting member 12 is a thin plate-shaped member having a circular center portion formed in accordance with the circular shape of the crane support 3, as shown in FIG. I do. The pin fixing member 7 has a structure for pinning the belt 11 as shown in FIG. 3, and supports each end of the belt 11 with pins provided at both ends of the backing plate member 6 as shown in FIG. . The jack 8 is provided between the jack holding plate member 9 and the jack plate member 10, and the belt 11 is hung on the jack plate member 10. Although not shown, a guide for the belt 11 is provided on the jacking plate member 10 in order to prevent the jack 8 from shifting laterally and falling off.
[0008]
Next, the assembly of the lower support portion of the small crane mounting jig will be described. First, the lower connecting member 12 is fitted into the lower crane support 3, and the backing plate member 6 is fixed. Subsequently, the contact plate member 6 is applied to the column 1, and the crane support 3 is attached to the side surface of the column 1. On the other hand, the jack holding plate member 9 is applied to the column 1, the jack 8 is fixed to the jack holding plate member 9, and then the jack 8 is applied to the jack holding plate member 10. , And each end of the belt 11 is fixed to a pin of the pin fixing member 7. In this case, the jack 8 is on the opposite side of the small crane 2. When the jack 8 is jacked up in such a state, the jack 8 extends the belt 11 and fastens the crane column 3 to the column 1. In this way, the crane column 3 is attached to the column 1 with a gap corresponding to the width of the backing plate member 6.
On the other hand, when the jack 8 is jacked down, the belt 11 is slackened, and the mounting jig of the lower support portion is disassembled, and the crane column 3 can be removed from the column 1.
Here, when the crane support 3 is flange-connected, the gap corresponding to the width of the backing plate member 6 is determined by the fact that the diameter of the flange 3-1 is larger than the main body of the crane support 3, and This space is necessary when the crane support 3 cannot be brought into close contact with the column 1, such as when the diameter of the crane support 3 is larger than the diameter of the crane support 3.
[0009]
Next, the upper supporting portion of the small crane mounting jig has a lower portion in that the abutment plate member 6 does not have a thin plate-like member such as the lower connecting member 12 and the upper connecting member 13 is fixed to the crane support 3. Other than the support portion, the other configuration is the same as the mounting jig of the lower support portion. The upper coupling member 13 is provided on the opposite side of the control panel 4 as shown in FIG. The backing plate member 6 and the upper connecting member 13 are connected by bolts and nuts. Alternatively, the backing plate member 6 and the upper connecting member 13 may be integrally formed.
The assembling of the upper support portion is performed after the backing plate member 6 and the upper connecting member 13 are connected by bolts and nuts, and when the backing plate member 6 and the upper connecting member 13 are integrally formed, the belt 11 is connected to the backing plate member 6. After being supported by the pin fixing member 7, the operation is the same as the assembly of the lower support portion.
[0010]
In this manner, in the present embodiment, the belt is tightened by jacking up the jack, whereby the crane support can be easily attached to a column such as a frame. Of course, the belt can be loosened by jack-down of the jack, and the crane support can be easily removed from the column of the frame or the like.
[0011]
In the present embodiment, the lower supporting portion is configured such that the lower connecting member 12 is integrated with the backing plate member 6, but the upper supporting member 13 is used in place of the lower connecting member 12, and The configuration may be exactly the same.
Further, in the present embodiment, the upper support portion is provided with the upper coupling member 13 on the opposite side of the control panel 4, but when the upper support portion is provided at a position of the crane support different from the place where the control panel 4 is installed, It goes without saying that the same structure as the mounting jig for the lower support portion may be used.
[0012]
【The invention's effect】
As described above, according to the present invention, the belt (steel band) is tightened by jacking up the jack, the crane support is attached to a pillar such as a frame, and the belt (steel band) is relaxed by jacking down the jack. Therefore, since the crane support is removed from a column such as a frame, the labor and time required for attaching and detaching the crane can be reduced as compared with fixing with a bolt and a nut, and the construction jig can be simplified. Consequently, it is possible to efficiently and efficiently attach and remove the crane support to a column such as a frame.
Further, according to the present invention, since a space is formed between the column such as the frame and the column for the crane, when the diameter of the connecting flange of the column for the crane or the diameter of the base for the crane is larger than the main body of the column for the crane, etc. Posts can be attached.
