Such a foldable gantry crane tent of the present invention is an awning installed in a gantry crane including a girder and a pair of saddles 100 for supporting girders at both ends of the girder, which are arched and both sides. A plurality of sets of frames (1), the ends of which are hinged to be rotatable on the same side of the pair of piers 100; A flexible cover (2) covering an upper portion of the set of frames (1); It is configured to include a winch (winch) (31) to relax the closing frame (1) the winding wire 3 and the winding wire (3) associated with the set.

,

또는 ∧) 프레임으로 구성된다.The frame (1) set is a skeleton that serves to expand or fold the flexible cover (2) at the bottom of the flexible cover (2) at least two arches (

,

Or iii) a frame.

In one embodiment (attached photo) of the present invention, the set of frames (1) is connected to a fixed frame 11 fixed to the pier 100, the fixed frame 11 and the flexible connection wire (1a) It may be composed of a rotating frame (12). At this time, both ends of the frame is hinged to be rotatable to the bracket 10 fixed to the piers (see Fig. 4b). On the other hand, since the fixing frame 11 is to function to fix one end (girder side) of the flexible cover 2, it is not necessarily in the form of a conventional frame, and also necessarily be connected to the bracket as shown in Figure 4b Of course, there is no need.

Meanwhile, one or more intermediate frames 13 may be further installed between the fixed frame 11 and the rotation frame 12 as shown in FIGS. 4 and 5. The intermediate frame 13 is also rotatably connected at both ends to the bracket 10 like the pivoting frame 12 so that the tent of the present invention is unfolded at regular intervals as shown in FIG. 4 and folded. In the state, as shown in FIG. Hereinafter, an example in which a plurality of intermediate frames 13 are installed between the fixed frame 11 and the rotation frame 12 will be described.

The flexible cover 2 is installed on the outside (upper) of the set of frames 1 configured as described above. The flexible cover 2 is a frame in which the pivoting frame 12 is fully extended so that the pivoting frame 12 is rotated away from the fixed frame 11. It is installed to be covered between the (11, 12, 13) or the top of the frame (11, 12, 13). As shown in FIG. 4A, the plurality of connection wires 1a connected between the frames 11, 12, and 13 serve to connect each other while maintaining the maximum spacing of two adjacent frames, as well as the flexible cover 2. It also serves to support (hold) the middle of the flexible cover 2 below.

According to a preferred embodiment, the center of gravity of the pivot frame 12 in the folded state of the tent is designed to be outside the pivot axis of the pivot frame 12 (i.e., bracket 10) (e.g., 90 ° Designed to be somewhat less built). As a result, simply unwinding the winding wire 3 when the tent is unfolded, and the tent is unfolded by the asymmetric center of gravity of the rotation frame 12.

FIG. 4B shows an enlarged view of the ends of the frames 11, 12, 13 connected to the piers 100 rotatably by the bracket 10.

As described above, the pulley wire 3 is pulled by the winch 31 to pull the intermediate frame 13 including the pivoting frame 12 toward the pier and thus the flexible cover 2 is folded to fold the tent. Get kicked.

In this way, the winding wires 3 connected to the pivoting frame 12 in order to allow the frames 12 and 13 to be sequentially folded when the tent is walked, as shown in FIGS. 4C and 4D, the intermediate frame 13. It is connected to the winch 31 via the roller (3a) installed in, between the portion connected to the winch 31 of the winding wire (3) and the inner middle frame 13 of the roller installed in the support (5) The force pulled by the twisted wire (3) was directed upward through the center of the gantry crane (ie, toward the girder side).

The winch can be installed anywhere, but it is desirable to be at the top of the girder in order to increase the operating efficiency and to prevent interference with other installations.

As described above, the tent of the present invention in which the plurality of frames 12 and 13 are rotatably connected may be struck in the middle of the tent due to the weight of the frames 12 and 13 or by the weight of snow or rain. In the middle of the rotation frame 12 and the intermediate frame 13, a support wire 4 for supporting the weight of the frame 12, 13 is installed, the support wire 4 is suspended on the support (5).

That is, as shown in FIGS. 2 to 5, the tent is supported by the support wire 4 in the state where the tent is fully extended by installing one or more support wires 4 in the middle of the frames 12 and 13. ) Is prevented from being struck in the middle of the frames 12 and 13.

When the support wire 4 is installed in this way, when the tent is folded, the support wire 4 is in a stretched state, and the support wires 4 are entangled with each other. Therefore, in the present invention, as shown in FIG. 3, two support wires 4 are provided at intervals for each frame 12 and 13, and the support wires connected to each frame are connected by separate springs 41. This prevents tangling with other support wires. In one embodiment of the present invention (FIG. 4A), two support wires 4 are installed per frame, but it will be obvious that the number of support wires 4 can be increased or decreased according to the load of the frame.

For example, if two support wires 4 are installed in one frame 12 and 13 and a spring is installed between the two support wires 4, the spring 41 pulls the support wires 4 when the tent is folded. As shown in FIGS. 3 and 4D, the two support wires 4 are kept in a tense state, thereby preventing them from becoming tangled with the support wires 4 installed in the other frame.

As shown in FIG. 6 and shown in FIGS. 8A to 8C, the pivoting frame 12 installed outside of the frames 11, 12, and 13 constituting the foldable gantry crane tent of the present invention configured as described above is illustrated in FIGS. Likewise, by constructing three-dimensionally to reinforce the strength and construct a heavy, the fixed frame 11 and the intermediate frame 13, which is a frame installed inside, as shown in Figures 7 and 8a to 8c, It is desirable to minimize the weight while maintaining the overall strength.

The reason why the outer rotating frame 12 is configured to be heavy is that when the winding wire 3 is loosened by the driving of the winch 31, the rotating frame 12 is formed by the weight (position of the center of gravity) of the rotating frame 12 itself. ) So that the tent can unfold.

In addition, the fixed frame 11 and the intermediate frame 13 is a simple and lightly configured reason is that if the weight of the entire tent is too heavy, the construction is difficult, as well as to prevent accidents from being separated from the piers by its own weight in the installed state It is to.

(2) The present invention also relates to a folding tent mounting gantry crane equipped with the above-described foldable gantry crane tent. Conventional gantry cranes are well known in the art, and the structure and function of the foldable gantry crane tent according to the present invention have been described in detail above. Therefore, the additional description of the folding tent mounting gantry crane itself equipped with a foldable gantry crane tent is omitted.

An example of the folding tent mounting gantry crane according to the present invention is shown in the photographs in FIGS. 8A to 8C. Description of each component is as above-mentioned.

(3) Hereinafter, the operation of the foldable gantry crane tent according to the present invention configured as described above is outlined.

As described above, the center of gravity of the rotating frame 12 in the folded state (see FIGS. 8A to 8C) is slightly outwardly directed. For example, the rotatable frame 12 is designed to stand slightly less than 90 °, that is, the distal end (upper part) is inclined outward than the bracket 10 connection part (lower part) of the rotating frame 12. .

First, when the tent is unfolded, the winch 31 is operated to loosen the winding wire 3 so as to be rotated downward by the self-weight (weight center position) of the distal end (upper portion) of the rotation frame 12, thereby connecting it. As the wire 1a is pulled, the intermediate frames 13 also rotate so that the flexible cover 2 is unpowered.

Once the tent is unfolded as desired, stop the winch 31 so that the tent is no longer unfolded.

In this case, the support wire 4 supports the frames 12 and 13 in a state in which the frames 12 and 13 are suspended from the support 5, and the spring 41 is in an unfolded state (FIGS. 4D, 8A, 8b).

When the winch 31 is driven in the opposite direction to fold the tent, the winding wire 3 is pulled by the winch while the rotation frame 12 is pulled toward the piers 100.

At this time, the distance between the frame connection end of the support wire 4 and the support connection end becomes short, so that the support wire 4 becomes loose, but the spring 41 pulls the support wire 4 and the support wire 4 is tight. The tension is maintained so that the support wires are not entangled with each other (see FIG. 4D).
