Abstract

The crane dustproof equipment of the present invention relates to a dustproof equipment installed by a ceiling crane installed in a clean room in order to prevent scattering of rust dust, which is a pollutant that may occur in rails and wheels during movement.

Conventionally, whenever a ceiling crane installed in a clean room or the like is used, contaminants such as rust dust or fine dust may come off due to friction during movement of the crane, such as rust on rails and wheels of a crane.

Therefore, the present invention maintains high cleanliness in many ceiling crane operations performed in a clean room space, and enables operation of the overhead crane without worrying about contamination of the test object, thereby improving operation and work efficiency of the clean room, and clean room. It provides the effect of extending the life of expensive high density filter installed for operation.

The present invention relates to a crane, in order to prevent the scattering of contaminants such as rust dust and fine dust that may occur during the use of the crane, a dustproof member is installed on the moving part of the crane, such as wheels or rails of the crane, Dustproof equipment is presented.

Heavy equipment often needs to be operated in a clean room depending on the equipment's characteristics. In this case, the surrounding equipment and test facilities must be suitable for the clean condition.

In particular, expensive test objects such as satellites can be fatally damaged by small contaminants, so special attention must be paid to the management of test objects.

Since the crane installed in the ceiling of a clean room is located on the heavy object because of the characteristics of the crane, it is almost unprotected by contaminants that can fall from above.

Therefore, the management of the overhead crane is one of the facilities to pay special attention, and as a way to manage this well, it prevents the fallout of pollutants such as rust dust or fine dust which may be caused by the friction of the rail and the wheel when using the crane. Therefore, there is a need for a method to prevent the possibility of lethal damage to expensive specimens due to the deterioration of cleanliness of the clean room.

The present invention solves the contamination problem that may occur during the use of the overhead crane in the clean room, and by moving the crane to reduce the operating cost by reducing the number of replacement of the high density (HEPA) filter to maintain the cleanliness of the clean room, The purpose of the present invention is to provide a dustproof installation technology of a crane having a dustproof member installed at the site.

The dustproof equipment of the crane of the present invention for achieving the above object,

Dustproof members are installed around the wheels and rails of the overhead crane to prevent dust from scattering when the wheels and rails are rubbed to the outside.

In addition, the anti-vibration member is ① is coupled to the winding motor box of the crane and the dust cover that surrounds the upper, front and rear and both sides of the wheel, and ② is installed on both sides of the rail, the top is the lowest end of the dust cover 160 And at least equal to or higher than the vibration isolator.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a form in which the crane of one embodiment of the present invention is installed, Figure 2 is a view for explaining the dustproof equipment installed on the moving part of Figure 1, the state seen from the front and side, respectively.

In general, overhead cranes are used to lift heavy loads. In general, since the work performed in a space such as a clean room should be basically performed in a state capable of maintaining cleanliness, as described above, the present invention generally includes a cover plate installed on rails and wheels of a commonly used overhead crane. This is to prevent rust dust, which is a pollutant.

As shown, the crane of this embodiment is provided with a rail 110 along the wall in a ceiling such as a test hall (long). The ceiling crane 150 is installed to move along the rail 110.

In addition, in such a crane, the rail 110 may be installed in a double or triple structure, so that the movement in space, ie, movement in the X, Y, and Z axes, may be installed.

In the present embodiment, when the ceiling crane 150 is to be used in a clean room or the like, as described above, pollutants such as rust dust or dust that may be generated by friction between the crane wheel 151 and the rail 110. In order to minimize contamination of the clean room and the test object, a dustproof member including a dustproof cover 161 and a dustproof plate 120 around the crane wheel (hereinafter referred to as “wheel”) 151 and the rail 110 is provided. Was installed. This will be described in detail below.
In order to prevent the dustproof plate 120 formed of a material such as stainless steel or surface-treated steel plate around the rail 110 by welding or the like, and then contact the bottom with an airtight agent 125 such as silicon to maintain airtightness. Formed by applying, the wheel 151 is also formed in the same way dustproof cover 160.

The anti-vibration plate 120 is installed on both sides of the rail along the rail 110 of the crane, the upper end is formed at least the same or higher than the lowest end of the anti-vibration cover 160, the ceiling crane 150 rail Contaminants such as rust dust or dust that may be generated during the movement along 110 are prevented from being pushed out to both sides.

In addition, the anti-vibration cover 160 is formed to surround the upper, front and rear and both sides of the wheel 151 while being coupled with the winding motor box 152 of the crane, the wheel 151 of the moving ceiling crane 150 It was developed to cover. In addition, in order to fix the dust cover 160 to the winding motor box 152, the fixing plate 161 is integrally formed on a surface of the dust cover to face the winding motor box 152, and the fixing plate 161 is formed. ) And the winding motor box 152 by screwing to enable the fixing of the dust cover (160). In this case, the fixing plate 161 and the dust cover 160 are preferably connected to each other by the reinforcing rib 162 to prevent deformation of the fixing plate 161.

The crane dustproof equipment of this embodiment, the dustproof plate 120 is installed in parallel to the rail 110 in a state perpendicular to the ground, and the dustproof cover 160 formed to simply wrap the outside of the crane wheel 151 is In addition to the simple structure as shown in Figure 2, it can be fixed and released with a bolt or the like for the convenience of inspection and repair of the crane, it is very easy to inspect and clean the equipment.

In addition, the material of the dustproof plate 120 and the dustproof cover 160 may be formed of a polymer material such as plastic or ceramic, in addition to a metallic material such as stainless steel or iron.

Therefore, through the above-described configuration of the present invention, when the crane crane 150 moves along the rail 110, the wheel 151 of the crane may be generated by friction with the rail 110, such as rust dust or fine dust It is possible to effectively prevent the contaminants of the clean room and to protect from contamination of the test object, as described above can be formed in a structure capable of separating and separating the dustproof plate 120 and the dustproof cover 160. It is possible to carry out more variously based on the technical concept of this invention, such that various materials can also be utilized.

As described above, the present invention improves the operation and work efficiency of the clean room by installing dustproof materials on the rails and wheels of the ceiling crane, and thus provides high cleanliness when working on a large number of ceiling cranes performed in a clean room. It enables to operate the overhead crane without worrying about the contamination of the test object, and extends the life of the expensive high density filter installed in the clean room.
