Abstract

PROBLEM TO BE SOLVED: To contrive improvement of attachment by providing the bolt hole of a valve side attaching seat plate outside the substantially parallel both edges of a machine body-side attached plate, and tightening an L-shaped hook metal fitting hooked on both the edges of the attached plate by a bolt inserted in the bolt hole. SOLUTION: The bolt hole of an attaching seat plate 12 integrated with a valve 11 is provided outside both substantially parallel edges corresponding to the attached plate 13 of a machine body side. Next, an L-shaped hook metal fitting 14 with a screw hole is disposed on the attaching face side of a bolt hole, hooked on both the edges of the attached plate 13, and the metal fitting 14 is tightened by a tightening bolt 15 inserted in the bolt hole of the attaching seat plate 12 to fix the attaching seat plate 12 on the attached plate 13. In addition, one thin plate 17 composed of rubber material exists between the hooked face part of the attached plate 13 and the hook face of the metal fitting 14. Thereby a valve can be attached without using a specific tool or the like, and damage can be prevented at the time of attaching of the attached plate.

Conventionally, in a construction machine, for example, when a new special work is to be performed, a special work machine may be attached to the tip of the work attachment to cope with the special work. In such a case, it is necessary to fix a valve of a hydraulic device or the like necessary for a hydraulic circuit of the special working machine to the body. As the fixing means, a screw hole for a bolt is drilled at a position corresponding to a bolt hole of a mounting seat plate formed integrally with the valve, or a block with a screw hole is attached to a mounting surface portion of the body. We are trying to weld. However, the method of drilling a screw hole for a bolt as the fixing means requires an electric ball and a tapping tool for drilling, and requires a considerable amount of labor and time for drilling the screw hole, and is inconvenient. . In addition, a method of welding a block with a screw hole requires a welding machine, and it has been necessary to pay attention to strength, such as preventing welding distortion and cracking caused by welding. According to the means, for example, if the surface to be mounted is a painted surface, the painted surface is damaged, and when the valve is removed when it is no longer needed, the screw hole or the block with a screw hole remains, It rusted and looked bad. The present invention eliminates the need for a processing tool or tool for mounting a valve, and can also be moved to a required position and mounted if the width dimensions of the mounting plate are the same, and the valve is not required. It is an object of the present invention to provide a valve mounting device for a construction machine in which the surface to be mounted does not differ from the surface to be mounted before mounting the valve even when the valve is removed.

[0004]

SUMMARY OF THE INVENTION According to the present invention, there is provided a valve mounting apparatus in which a valve of a hydraulic device or the like is mounted on a body of a construction machine by bolt tightening, and a mounting seat fixed integrally with the valve. At least one bolt hole is drilled at a position outside the corresponding substantially parallel edges of the mounting plate of the fuselage, and a screw hole is provided on the mounting surface side of the drilled bolt hole. The L-shaped hooks are arranged and hooked on the both edges, and a tightening bolt is passed through the bolt hole, and the L-shaped hook is fastened to fix the mounting seat plate to the mounting plate. I did it. In the case described above, substantially the entire surface between the opposed facing surfaces of the mounting seat plate and the mounted plate is further reached between the hooked surface portion of the edge portion of the mounted plate and the hooking surface portion of the L-shaped hooking member. Until then, one thin rubber sheet was interposed.

According to the present invention, at least one bolt hole is formed in each of the mounting seat plates integrally fixed to the valve at positions outside the corresponding substantially parallel edges of the mounting plate of the body. An L-shaped hook with a screw hole is arranged on the mounting surface side of the drilled bolt hole and hooked on both edges, and a tightening bolt is passed through the bolt hole. Since the hooks are tightened, machining tools and equipment for mounting the valve are not required when mounting the valve, and if the width of the mounting plate on the fuselage side is the same, move it to the required position. It is also possible to attach it. One sheet is provided over substantially the entire surface between the facing surfaces of the mounting seat plate and the mounting plate, and further between the hooking surface portion of the edge portion of the mounting plate and the hooking surface portion of the L-shaped hooking member. However, since the thin plate of the rubber material is interposed, the opposing surfaces of the mounting seat plate and the mounted plate can be in close contact with each other via the thin plate, and the occurrence of damage at the time of mounting to the mounted plate can be prevented. Therefore, even when the valve becomes unnecessary and is removed, the surface to be mounted can maintain the state of the surface to be mounted before the valve is mounted.
