The hanger for attaching the arrangement object of the construction machine according to the embodiment of the present invention will be described with reference to FIGS. 1 to 15.

FIG. 1 shows an example of a construction machine to which a hanger according to the present embodiment is applied. The work attachment 100 of the construction machine shown in FIG. 1 is a so-called long attachment, and includes a base end side boom 110, an inter boom 120, a tip end side boom 130, and an arm 140. The base end side boom 110 is composed of a plurality of boom bodies 111 to 114 that can be divided. Further, the tip side boom 130 is also configured to be separable. Each member of these work attachments 100 is connected by a pin inserted through a pin connecting hole.

When the construction machine is transported, each member of the work attachment 100 is divided and transported (hereinafter, each member obtained by dividing the work attachment 100 is simply referred to as an "attachment"). At that time, it is necessary to have a means for holding a hose (an example of an arrangement) provided in each attachment and whose end is not restrained. The hanger of this embodiment is used to hold such a hose and is applicable to any attachment having pin connecting holes.

As shown in FIG. 2, the hanger 1 includes a rod 2, hooks 3 (3A, 3B), and stoppers 4 (4A, 4B). In the present embodiment, the rod 2 is a round bar having a circular cross section and has a hollow pipe shape.

The hooks 3A and 3B for holding the hose are fixed to both ends of the rod 2. Hereinafter, as shown in FIG. 2, the left and right hooks are referred to as "hook 3A" and "hook 3B", but the hooks 3A and 3B have symmetrical shapes, and when the two are not distinguished, they are simply "hooks". Call it "3". The same applies to the pin connecting holes 51 (51A, 51B) of the stopper 4 (4A, 4B) and the attachment 5 (see FIG. 11).

Two hook members 31 are provided in parallel on each hook 3, and these hook members 31 are attached to the rod 2 via a mounting plate 33. Each hook member 31 is a concave plate member, and has a concave hose receiving surface 32 for receiving a hose 6 (more specifically, a multi-coupler 7 described later).

Further, disk-shaped stoppers 4A and 4B are provided between the hooks 3A and 3B on the rod 2. When the hanger 1 attached to the attachment 5 tries to move in the long direction (axial direction of the rod 2), the stoppers 4A and 4B come into contact with the attachment 5 to limit the movement of the hanger 1.

As shown in FIG. 3A, the hook 3 composed of the two hook members 31 and the mounting plate 33 fits in the pin connecting hole 51 in a side view (viewed from the axial direction of the rod 2). It is configured in such a size. That is, the hook 3 has a size that allows it to be inserted through the pin connecting hole 51.

Further, as shown in FIG. 3B, the stopper 4 is configured as a disk having a size slightly smaller than that of the pin connecting hole 51. That is, the stopper 4 is also large enough to be inserted into the pin connecting hole 51.

As shown in FIGS. 3A and 3B, the center of the stopper 4 coincides with the central axis C of the rod 2. On the other hand, with respect to the hook 3, the rod 2 is attached to the end of the attachment plate 33 instead of the center.

In this way, the hook 3 may be arranged so as to be offset from the central axis C of the rod 2, and the combined size of the hook 3 and the stopper 4 in the side view may protrude from the pin connecting hole 51. It is the size. Therefore, as will be described below, when the hanger 1 is attached to the attachment 5, the hanger 1 is inserted into the pin connecting hole 51 while being displaced in the direction orthogonal to the axial direction.

A procedure for attaching the hanger 1 to the pin connecting holes 51A and 51B of the attachment 5 will be described with reference to FIGS. 4 (a) and 4 (b) to 8 (a) and 8 (b).

First, as shown in FIGS. 4A and 4B, the hook 3A is inserted into the pin connecting hole 51B (insertion direction S1).

Next, as shown in FIGS. 5A and 5B, the hanger 1 is shifted to a position where the stopper 4A passes (moving direction S2), and the stopper 4A is passed through the pin connecting hole 51B.

Subsequently, as shown in FIGS. 6A and 6B, the hanger 1 is shifted (moving direction S3) before the hook 3A is passed through the second pin connecting hole 51A, and the hook 3A is inserted into the pin connecting hole 51A. Move to the position where.

Further, as shown in FIGS. 7 (a) and 7 (b), the hanger 1 is shifted to the position where the stopper 4B passes through the first pin connecting hole 51B (moving direction S4), and the stopper 4B is inserted into the pin connecting hole 51B. Let it through.

Then, after passing the stopper 4B through the pin connecting holes 51B, the rod 2 is placed against the ends of the pin connecting holes 51A and 51B as shown in FIGS. 8A and 8B (movement direction S5).

FIG. 9 shows a state in which the hanger 1 is placed at the end of the pin connecting hole 51. Here, the position of the center of gravity G of the hanger 1 and its action and effect will be described.

As shown in FIG. 3A, the center of gravity G of the hanger 1 is at substantially the same height as the central axis C of the rod 2 with the hose receiving surface 32 (see FIG. 2) of the hook 3 facing upward. If the hose receiving surface 32 of the hook 3 is facing upward and the center of gravity G is higher than the central axis C, the hanger 1 will rotate when placed at the end of the pin connecting hole 51 and will be pulled up and down. It may be repeated. Therefore, it is preferable that the center of gravity G of the hanger 1 is at the same height as the central axis C of the rod 2 or at a lower height than the central axis C with the hose receiving surface 32 of the hook 3 facing upward.

Further, due to the positional relationship between the hook 3 and the rod 2 described above, the center of gravity G of the hanger 1 is located at a position shifted in the horizontal direction with respect to the central axis C of the rod 2. More specifically, the center of gravity G is orthogonal to the central axis C in both the direction in which the hose receiving surface 32 faces (above in FIG. 3A) and the axial direction of the rod 2 (FIG. 3). It is in a position shifted to the right of 3 (a)). As a result, as shown in FIG. 9, when the hanger 1 is placed at the end of the pin connecting hole 51, the hanger 1 is tilted toward the center of gravity G with respect to the central axis C. In the present embodiment, since the hose 6 extends diagonally downward as shown in FIGS. 11 and 15, if the hanger 1 is tilted as described above, an extra force is applied to the hose 6 with the hose 6 attached. It's convenient. As described above, in the present embodiment, when the hanger 1 is placed at the end of the pin connecting hole 51, the center of gravity G of the hanger 1 is set so that the hose receiving surface 32 of the hook 3 faces upward (including diagonally upward). It is set.

In this embodiment, as shown in FIG. 10, the hose 6 is attached to a multi-coupler 7 that can handle a plurality of hoses together. The multi-coupler 7 shown in FIG. 10 is a member on the male side. The multi-coupler 7 has a base 71 and a plurality of hose attachment portions 72 provided on the base 71. A plurality of hoses are also attached to members on the female side (not shown). By attaching and detaching the male side member (multi-coupler 7) and the female side member (not shown), a plurality of hoses can be attached and detached together. Note that, in FIGS. 11 to 15, only one hose 6 is shown for convenience.

11 to 13 show a state in which the hanger 1 is attached to the pin connecting hole 51 and then the hose 6 (more specifically, the multi-coupler 7 to which the hose 6 is attached) is attached to the hanger 1. As shown in FIG. 13, in the holding state of holding the hose 6, the hooks 3A and 3B are located outside the pin connecting holes 51A and 51B. On the other hand, the stoppers 4A and 4B are located inside the pin connecting holes 51A and 51B. Although not shown, the multi-coupler 7 is fixed to the hooks 3A and 3B by using a binding band, a string, or the like.

Further, as shown in FIG. 14, in a state where the multi-coupler 7 is attached to the hanger 1, the multi-coupler 7 is attached so as to sandwich the base 71 of the multi-coupler 7 between the two hook members 31.

FIG. 15 shows the force acting on the hanger 1 to which the hose 6 is attached. Gravity F1 due to the weight of the hose 6 and the multi-coupler 7 and the repulsive force F2 of the hose 6 mainly act on the hanger 1. By these forces, the hanger 1 is received by the end of the pin connecting hole 51 and pressed against it to stabilize it.

According to the hanger 1 according to the embodiment described above, since the size is such that the entire hanger 1 can be inserted into the pin connecting hole 51, no tool is required at the time of mounting, the number of parts is small, and the workability is good. Further, in the holding state of holding the hose 6, the rod 2 is pressed against the end of the pin connecting hole 51 by the own weight and the repulsive force of the hose 6, so that the hose 6 is stably held. Further, since the entire hanger 1 is integrally formed, there is little risk of loss.

Further, according to the hanger 1 according to the above-described embodiment, since the stopper 4 is provided, it is possible to restrict the hanger 1 from moving in the axial direction even if the hook 3 is located away from the attachment 5. The hose 6 can be stably held.

Further, according to the hanger 1 according to the above-described embodiment, since the stopper 4 is provided so as to be located inside the pin connecting hole 51 in the holding state of the hose 6, the total length of the rod 2 can be shortened and the mass can be reduced. That is, since the hanger 1 is inserted while shifting when the hanger 1 is attached to the pin connecting hole 51B as described above, the distance D1 between the hook 3 and the stopper 4 (see FIG. 5B) is the thickness of the attachment 5. The hanger 1 cannot be shifted unless it is made larger than D2. If the stopper is provided so as to be located outside the pin connecting hole 51, the hook must be further provided at a position where the distance D2 is secured outside the stopper, so that the total length of the hanger becomes long.

As shown in FIG. 13, in the vicinity of the pin connecting hole 51 of the attachment 5, an inner bracket 56 is provided on the inner side surface of the side plate 55, and outer brackets 57 and 58 are provided on the outer surface of the side plate 55. The thickness D2 is the total thickness of the side plate 55, the inner bracket 56, and the outer brackets 57 and 58.

Further, the stopper 4 is provided so as to have a size and a mounting position so that the hanger 1 can be inserted into the pin connecting hole 51 to be in a holding state (a state in which the hose is held). That is, in the present embodiment, the combined size of the hook 3 and the stopper 4 when viewed from the axial direction (see FIG. 3A) is such that it protrudes from the pin connecting hole 51, as described above. Since the axial distance D1 between the hook 3 and the stopper 4 is secured, the hanger 1 can be inserted into the pin connecting hole 51 to be in the holding state. Note that, unlike the present embodiment, if the combined size of the hook and the stopper when viewed from the axial direction fits within the pin connecting hole, the hook and the stopper may be brought closer to each other in the axial direction. The hanger can be inserted into the pin connecting hole to hold it.

Further, according to the hanger 1 according to the above-described embodiment, two hook members 31 are arranged side by side, and the two hook members 31 sandwich and hold the base 71 of the multi-coupler 7 (see FIG. 14). It can be stably held even with the hose 6 of.

Further, according to the hanger 1 according to the above-described embodiment, the hose receiving surface 32 of the hook 3 is configured to face upward when the hanger 1 is inserted into the pin connecting hole 51 and placed at the end of the pin connecting hole 51. Has been done. Therefore, when the hose 6 is attached to the hanger 1, the work of changing the direction of the hanger 1 becomes unnecessary, and the workability is improved.

Further, according to the hanger 1 according to the above-described embodiment, since the rod 2 is a round bar, the pin connecting hole 51 is not easily damaged. Further, since the rod 2 is a round bar and is easy to rotate, the center of gravity of the hanger 1 is set as described above so that the hanger 1 faces a desired direction when it is placed at the end of the pin connecting hole 51. be able to.

The hanger for attaching the arrangement object of the construction machine according to the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the range described in the claims.

In the above-described embodiment, the rod 2 is a straight rod, but the rod may be bent as long as the hanger 1 can be inserted through the pin connecting hole 51. For example, as shown in FIG. 16, the rod 202 may be bent within a range that allows it to be inserted into the pin connecting hole 51. Also, the rod may be curved.

Further, in the above-described embodiment, the rod 2 is a round bar having a round cross section, but the cross section of the rod 2 may be another shape such as an ellipse, a quadrangle, or a hexagon.

Further, in the above-described embodiment, the hanger 1 is provided with the stopper 4, but the stopper may not be provided. In this case, the hook may have a stopper function.

Moreover, the stopper may be made smaller. For example, if the hook and the stopper are configured to fit in the size of the pin connecting hole when viewed from the axial direction, it is not necessary to insert the hanger while shifting it when attaching it to the pin connecting hole. However, in order to exert the function of the stopper, it is preferable that the stopper is large to some extent.
