The present invention relates to a valve protective cover (cover) in the work line, but in more detail, as a cover for protecting the valve installed in the assembly or automobile supply pipe or hose supplying hydraulic or pneumatic in each process line The present invention relates to a valve cover which is easily removable and repaired.

In general, for example, a robot or various work tools are used for automobile assembly and manufacturing processes. Various energy sources are provided for such robots or work tools, such as power and hydraulic and pneumatic. In particular, when hydraulic and pneumatic are used as energy sources, such hydraulic and pneumatic pressures are supplied through pipes or hoses, and the amount and strength thereof are generally controlled by valves installed in the respective pipes or hoses.

However, such supply pipes or hoses are installed so that they are exposed directly to the ground, for example, paved with concrete and light flooring, and in particular, valves installed in such supply pipes or hoses can also be exposed, inadvertently manipulating the valves to provide accurate hydraulic and pneumatic Sometimes it interferes. Accordingly, in order to protect such a valve, a valve protection cover is generally provided at a portion where the valve is installed. An exploded perspective view showing such a general valve protection cover is shown in FIG. 1.

According to FIG. 1, the hydraulic or pneumatic supply pipe 1 is mounted and installed in the floor F of the process line which is not shown in detail. In addition, the supply pipe (1) is provided with a variety of control valve (2) to adjust the hydraulic or pneumatic. In particular, a protective cover 3 is provided for protecting and shielding such control valves 2. The protective cover 3 generally has a horizontal portion 3a and a vertical portion 3b formed on both sides of the horizontal portion 3a to form a valve receiving space. In addition, a fixing flange 3c is formed in each of the vertical portions 3b, and a bolt hole 4 is formed in each of the fixing flanges 3c.

Accordingly, the protective cover 3 is fixed to the fastening hole 6 drilled in the floor F by inserting a plurality of bolts 5 into the bolt holes 4 to protect the control valve 2 and Shield.

However, such a general protective cover 3 is not only easy to install and release, but also has the drawback that the maintenance of the control valve (2) is not quick. In more detail, in order to fix the valve protective cover 3 to the ground, a plurality of bolts 5 are fixed to the bolt holes 4 and the fastening holes 6 formed in the floor F, respectively, and the control valve 2 Even when the protective cover 3 is peeled off for repair, there is an inconvenience of releasing a plurality of bolts 5 through several bolt release processes. Such a delay in the installation and removal and the resulting maintenance of the control valve 2 inevitably result in the interruption of the operation, which inevitably leads to a decrease in productivity resulting in an increase in the manufacturing cost.

Therefore, the present invention has been devised to solve such a problem, and an object of the present invention is to provide a valve protection cover that is easy to install and remove in a work process line.

Another object of the present invention is to provide a valve protective cover that can be quickly installed and removed in the work process line, and thus can quickly repair the valve.

These objects are achieved by the preferred embodiment of the present invention, according to one embodiment of the present invention, the valve protection cover for protecting the valve installed in the supply pipe for supplying pneumatic or hydraulic pressure to the work line or assembly line is And a front wall, a rear wall, a first side wall, and a second side wall, each of which has a first opening for accommodating a worker's hand and a supply pipe therethrough. A base portion having a second opening; And a cover plate releasably inserted and fixed between the base parts, a plurality of rods formed at respective corners of the lower surface of the cover plate, flanges formed at ends of the rods, and the flanges. A cover part welded to and including an alignment pin fixed to the floor to be releasable; It consists of.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is an exploded perspective view of the valve protection cover according to the present invention, and FIG. 3 is a perspective view showing a state of use of the valve protection cover according to the present invention.

First, according to Figure 2, the valve protection cover according to the present invention is composed of a base portion 10 and the cover portion.

The base portion 10 is formed in a box shape with upper and lower portions open. The front wall 11 and the rear wall 12 are closed, and both side walls, that is, the first side wall 13 and the second side wall ( 14, a first opening 15 through which a worker's hand can enter and exit, and a second opening 16 through which a hydraulic or supply pipe 1 (not shown) passes are formed.

In addition, the cover portion 20 has a cover plate 21 for closing the upper portion of the base portion 10. Four rods 22 are welded and attached to respective corner portions of the lower portion of the cover plate 21. Of course, each rod 22 may be integrally formed with the cover plate 21.

The lower part of each rod 22 is also integrally formed with a flange 23, and each of the flanges 23 is welded with a pin that can be fixed to a floor (not shown). Is preferably a dowel pin 24.

According to FIG. 3, the base part 10 according to the present invention has a cover part 20 inserted therein. Referring to the installation method of the protective cover with reference to the base part 10, the base part 10 has a second opening ( It is mounted on the floor F so that the pneumatic or hydraulic supply pipe 1 may pass through 16). In this state, the cover part 20 is inserted through the upper part of the base part 10. In detail, each of the rods 22 formed on the cover part 20 includes the base part 10. When a force is applied to the cover plate 21 in a state of being inserted through each corner of the hole, each of the dowel pins 24 attached to the flange 23 of the rod 22 is drilled in the floor F (not shown). Not installed), the installation of the valve protection cover according to the present invention is completed.

Then, in order to remove the valve protection cover or to operate the valve, a hand is inserted through each of the first openings 15 formed in the base portion 10, and then the cover plate 21 is pulled in the vertical direction to the floor F. The cover part 20 is released from the base part 10 while the dowel pin 24 fixed to the cover is pulled out.

In this state, the valve can be easily operated. In addition, when the valve is required to be repaired and exchanged, the cover part 20 may also be removed, and then the valve may be repaired and replaced. Of course, the base part 10 and the cover part 20 may be removed at the same time. In this case, the cover part 20 is inserted into the base part 10 to each of the second openings 16. When both hands are inserted and pulled upwards, the entire protective cover can be removed from the floor (F).

After all, according to the valve protection cover of the present invention, the installation and removal of the valve protection cover is very quick, and the cover part or the whole cover can be removed by distinguishing the case of simply operating the valve from the case of repairing or replacing the valve. The valves can be operated or repaired very quickly and easily.

In particular, by using a dowel pin as a fixing means for fixing the cover to the floor, it is possible to simply fix and release a plurality of bolts without fastening and releasing each bolt like a conventional bolt fixing type, so that the entire valve protection cover The installation and removal of the valve is very quick, and thus, the operation and repair of the valve are very quick.

Although the preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and variations can be made without departing from the scope of the appended claims.
