The basic use principle of above-mentioned flame proof cable winding drum is: the electric current that the outside is rotated by the current collection slip ring is converted into static electric current to give power devices, but because partial structurtes unreasonable (electric clearance is too small, assembling is difficult), above-mentioned functions can not realize on overall safety ground.

The utility model content

The purpose of this utility model is to provide a kind of novel flame proof cable winding drum, and solution traditional cable reel is too small owing to the unreasonable partial electrical gap of causing of internal structure, the assembling difficulty, thereby has the problem of potential safety hazard.

The technical solution of the utility model is:

A kind of flame proof cable winding drum, have spindle assemblies, slip ring assembly, taper roll bearing and reel casing assembly, spindle assemblies inside is provided with explosion-proof chamber, explosion-proof chamber is positioned at spindle assemblies one end and is in the end of flame proof cable winding drum, and used a pair of taper roll bearing is installed on the spindle assemblies.

Described flame proof cable winding drum, the explosion-proof wiring post in the reel casing assembly evenly distributes by circumferencial direction.

Described flame proof cable winding drum, the outside driver plate of installing of the moving slip ring seat of slip ring assembly.

Described flame proof cable winding drum, the slip ring shaft end of slip ring assembly is provided with thrust bearing.

The beneficial effects of the utility model are:

1, the utility model flame proof cable winding drum has spindle assemblies, slip ring assembly, reel housing.The a pair of taper roll bearing of this reel is installed on the spindle assemblies fully, has guaranteed that motion steadily.Spindle assemblies inside is provided with explosion-proof chamber, and is in reel ends, and is convenient when making assembling.Be installed on the driver plate of moving slip ring seat outside, promptly strengthened electric clearance, improved assembling again.The end of slip ring assembly adds a thrust bearing, has improved the moving situation between slip ring, has improved fail safe.At the approximate equally distributed explosion-proof wiring post of circumferencial direction, effectively strengthen electric clearance, thereby improved fail safe, thoroughly eliminated the potential safety hazard of cable drum.

2, the utility model cable drum is according to GB3836.1-2000 " the general requirement of explosive gas atmosphere electrical installation ", and the standard design of GB3836.2-2000 " explosive gas atmosphere electrical installation flame-proof type " d " " is flameproof electrical apparatus.Its flame proof reel housing be form with welded steel plate two by the interconnective individual cavity of binding post, degree of protection IP54 is to adapt to special inflammable dangerous situation.
