Description

The present invention relates to a storage device.

In construction machinery, a hydraulic coupler is used as a connecting member for a supply path for supplying pressure oil from a hydraulic source arranged in an upper swing body to a desired location (see JP-A-2000-21188).

Japanese Unexamined Patent Publication No. 2000-21188

Patent Document 1 describes a configuration in which a hydraulic coupler is provided on the base end boom. The hydraulic coupler described in Patent Document 1 is connected to another hydraulic coupler provided at the tip of a hydraulic hose or the like extending from a hydraulic source to form a pressure oil supply path. If foreign matter such as metal pieces or dust is mixed in this supply path, it may lead to damage to the hydraulic equipment. Therefore, normally, the hydraulic coupler is held by attaching a cap to the tip portion in a state where it is not connected to another hydraulic coupler. However, according to this configuration, it may not be possible to prevent foreign matter from entering the supply path when the cap is lost.

Further, the hydraulic coupler provided at the tip of a flexible pipe such as a hydraulic hose is fixed and held to a bracket or the like in a state where it is not connected to another hydraulic coupler. For example, this hydraulic coupler is fixed to the bracket by fitting a hydraulic hose into a U-shaped notch provided in the bracket. However, depending on this configuration, even if the hydraulic coupler can be fixed to the bracket, it is necessary to attach the above-mentioned cap to the tip of the hydraulic coupler in order to prevent foreign matter from entering the supply path. Further, according to this configuration, since the hydraulic coupler is easily held upward, if the cap is lost, there is a possibility that foreign matter may be promoted to enter the supply path.

In view of the above inconvenience, it is an object of the present invention to provide a storage device capable of fixing a coupler and suppressing foreign matter from entering the coupler.

The casing device according to one aspect of the present invention made to solve the above problems is a casing device capable of storing a coupler unit having a support plate and one or a plurality of couplers penetrating the support plate in the thickness direction. A casing having a pair of side edges facing each other, an end wall having opposite upper and lower edges, and a pair of side walls connected to the pair of side edges of the end wall and facing each other. It is provided with a cover which is arranged on the upper part of the end wall and can cover the space surrounded by the end wall and the pair of side walls from above. The support plate has a locking portion that can be locked between the pair of side walls so as to face the wall, and the support plate is locked between the pair of side walls and the casing. Further, a fixing member for fixing the cover to each other is provided.

In the storage device according to one aspect of the present invention, the coupler can be fixed and foreign matter can be suppressed from being mixed into the coupler.

In this embodiment, the coupler 22 is a hydraulic coupler. The storage device 10 is connected to a pair of side edges 11a and 11b facing each other, an end wall 11 having opposite upper edges 11c and a lower edge 11d, and a pair of side edges 11a and 11b of the end wall 11, respectively, and is connected to each other. It includes a casing 2 having a pair of side walls 12 facing each other, and a cover 3 arranged above the end wall 11 and capable of covering the space S surrounded by the end wall 11 and the pair of side walls 12 from above. The pair of side walls 12 has a locking portion 12a capable of locking the support plate 21 between the pair of side walls 12 so that the tip portion 22a of the coupler 22 faces the inner surface of the end wall 11. The storage device 10 includes a fixing member 4 for fixing the casing 2 and the cover 3 to each other in a state where the support plate 21 is locked between the pair of side walls 12.

The storage device 10 includes a bottom plate 5 that closes the lower opening of the space S surrounded by the end wall 11 and the pair of side walls 12. The storage device 10 is fixed to, for example, a support base (not shown) installed in a construction machine. The bottom plate 5 may be a part of the support base, or may be a member separate from the support base. The bottom plate 5 and the support plate 21 may be separated from each other in a state where the coupler unit 20 is stored in the storage device 10. However, from the viewpoint of securely fixing the support plate 21 between the pair of side walls 12, the bottom plate 5 and the support plate 21 may be in contact with each other.

(Coupler unit)
As described above, the coupler unit 20 has a support plate 21 and a plurality of couplers 22. The support plate 21 has a substantially rectangular shape in a plan view (thickness direction view). The support plate 21 has a plurality of through holes 21a in the thickness direction. The coupler 22 penetrates through the through hole 21a. A hydraulic hose 23 is connected to the base end of the coupler 22. The support plate 21 has a pair of side end faces 21b facing each other. Convex portions 24 project from the pair of side end faces 21b, respectively. That is, the coupler unit 20 has a pair of convex portions 24 protruding from the pair of side end faces 21b. The convex portion 24 is, for example, rod-shaped. The pair of convex portions 24 project outward in the facing direction from the facing positions of the pair of side end faces 21b.

(casing)
The end wall 11 has a substantially rectangular shape in a plan view (thickness direction view). The planar shape of the end wall 11 is substantially equal to the planar shape of the support plate 21 of the coupler unit 20. As a result, the tip portions 22a of the plurality of couplers 22 are held between the support plate 21 and the end wall 11 in a state where the coupler unit 20 is stored in the storage device 10. More specifically, the tip portions 22a of the plurality of couplers 22 are held in a space defined by an end wall 11, a pair of side walls 12, a cover 3, a bottom plate 5, and a support plate 21.

The pair of side walls 12 are configured to have substantially the same shape. The pair of side walls 12 extend from the entire area of the side edges 11a, 11b of the end wall 11.
