Description

[0001] Cable tray having a cover fixing device [0002]

The present invention has a structure in which a cover disposed on an upper portion of a cable tray is connected to a cable tray in a simple and quick manner, and also has a structure in which an external dynamic impact factor such as a sea breeze and a vibration Since the connecting structure is not released to the dynamic impact factor and the connecting member for connecting the cover and the cable tray is disposed between the cover and the cable tray, the connecting member is not exposed to the outside, The present invention relates to a cable tray provided with a cover fixing device that minimizes safety incidents that may occur.

Generally, big and small diameter cables are arranged along the ceiling and floor or wall for supply of power supply or fluid to the factory, ship and offshore structure, and the cable arranged in this way gives inconvenience to aesthetics and passers In order to avoid this, the cable tray is used to support and fix it.

The cable tray can be classified into a ladder type, a bottom closed type, and a perforated type depending on the shape of the body. The cable tray can be classified into a straight type, an elbow type, a T type, a cross type, a straight type Reducer, Ducer and others.

As described above, the cable tray is commonly manufactured to have a predetermined length and then joined with other members. In order to interconnect the adjacent cable tray bodies, a separate connecting member and a fixing member are required, And the manufacturing cost (construction cost) is increased because the assembly is not smooth.

The above-mentioned problems have been filed and registered by the applicant of the present invention, and it is an object of the present invention to provide a cable tray integrated with a flexible joint for reducing the manufacturing cost by connecting the adjacent cable tray bodies without connecting members to each other, Document 1).

On the other hand, a cover is provided on the cable tray so that rainwater or foreign matter does not enter the cable tray.

FIG. 1 is a perspective view showing a cover fastening device of a conventional cable tray (Patent Document 2), and FIG. 2 is a sectional view showing a cover fastening device of a conventional cable tray.

As shown in the figure, a conventional cable tray cover fastening apparatus includes a tray body 10 having a rung 3 supporting the cable 2 across a pair of beams 1, A request 6 is formed in both sides in the longitudinal direction of the cover 5 and a beam 5 of the cover 5 is attached to the beam 1 of the tray body 10 And a clamp 7 having elasticity is fitted to fix the clamp 7 to the request 6 and fix it.

At this time, in order to fix the cover 5 on the pair of beams 1, the structure of the clamp 7 includes a lower engaging portion 7a which is engaged with the vertical portion 1 'of the beam 1, A bending pressing portion 7c having a V-shaped fastening portion 7b corresponding to the shape of the request 6 so as to press the request 6 of the bending portion 5 and the lower bending portion 7a and the bending pressing portion 7c And a connecting portion 7d which integrally connects the connecting portions 7a and 7b.

However, in the conventional cover fastening apparatus for a cable tray having such a fixing structure, the lower fastening portion 7a constituting the clamp 7 is simply fitted to the vertical portion 1 'of the beam 1, Shaped coupling portion 7b fixes between the pair of beams 1 and the cover 5 so as to simply press the request 6 of the cover 5. [

In this case, since the clamp 7 uses an elastic material for facilitating the fixing operation, when the cover fastening device of the conventional cable tray is installed on the outside, when a twist occurs due to the wind like a sea breeze, The clamp 7 having an elastic material for fixing between the pair of beams 1 and the cover 5 is also easily distorted and deviated from the pair of beams 1 and the cover 5. As a result, There arises a problem that the cover 5 fixed to the upper part of the body 1 is unlocked.

This is because, even when installed inside, even when external dynamic shocks such as vibrations generated in accordance with the driving of a machine installed in a room are continuously transmitted to the pair of beams 1 and the cover 5, The cover 5 fixed to the upper portion of the pair of beams 1 is unfixed due to the twist deformation caused by the deformation of the cover 5 and the deformation of the cover 5 due to the torsional deformation.
