Flame proof box is drawn by cable gland.
According to above-mentioned crane flame-proof type lifting height limiter, the flame proof seat at the mating surface of flame proof box with setting
There is O-ring seal.
According to above-mentioned crane flame-proof type lifting height limiter, the flame proof box and flame proof seat are to meet flame proof
It is required that structure.
According to above-mentioned crane flame-proof type lifting height limiter, the cable gland is explosion-proof type cable filler
Letter.
Compared with prior art, the beneficial effects of the utility model：
1. the utility model structure includes cable gland, flame proof box, modularization lifting height limiter and flame proof seat, every
Quick-fried seat is equipped with flame proof box, and seal cavity is formed between the inside of flame proof box and the upper surface of flame proof seat, is equipped with seal cavity
Modularization lifting height limiter, modularization lifting height limiter are fixed on flame proof seat, at the center of flame proof seat be equipped with to
Under straight slot, the bottom of flame proof seat offers flame proof seat slot, the output of modularization lifting height limiter along around straight slot
Axis may pass through straight slot and the outflow position of the output shaft is sealed by sealing ring, and sealing ring is arranged in flame proof seat slot；It is described
The upper end of modularization lifting height limiter is equipped with lead-out wire, and lead-out wire draws flame proof box by cable gland；Modularization rises
Rise limiter output shaft end designs a seal groove, sealing ring can be installed additional, to ensure explosive-proof grade and degree of protection, outlet
End is using the cable gland for meeting flame proof requirement；The structure design is simple in a word, superior performance, and explosion-proof security is high.
With being equipped with O-ring seal at the mating surface of flame proof box, 2. which exists flame proof seat described in the utility model structure
Flame proof box is with flame proof seat installation mating surface, designing the seam allowance length for meeting flame proof requirement, installing O-ring seal additional, formation meets
II C grades of flame proof design.
