Abstract
The utility model relates to a safety ladder used in construction of a continuous casting rotational flow sedimentation tank, and belongs to a construction safety protection device. The safety ladder is characterized by mainly comprising a straight ladder body and a cage, wherein the straight ladder body consists of front and rear main vertical rods and horizontal rods; the front and rear main vertical rods are vertically arranged symmetrically; the horizontal rods are uniformly welded between the front and rear main vertical rods horizontally from top to bottom; the cage is welded on the left side of the straight ladder body and mainly comprises an auxiliary vertical rod and arc protection rods; the front and rear ends of each arc protection rod are uniformly welded on the front and rear main vertical rods of the straight ladder body correspondingly from top to bottom; and the auxiliary vertical rod is vertically welded in the middles of the protection rods, so that the firm safety ladder is formed by assembly welding. During use, the safety ladder is fixedly arranged on the wall of the rotational flow sedimentation tank through embedded parts, operating personnel are safe and can temporarily rest when climbing up and down the ladder, and the ladder is safe and reliable.
Description
Technical field
The utility model belongs to the construction safety protection device, especially relates to a kind of continuous casting sedimentation basin construction safety climbing ladder.
Background technology
In the metallurgy industry steel-making continuous casting engineering, the body of rotational flow settling pond is underground reinforced concrete tube structure, the absolute altitude of this rotational flow settling pond bottom is negative more than 20 meter, usually adopt catladder as rotational flow settling pond bottom operating personnel's upper lower channel, but because the rotational flow settling pond bottom is darker, if the operating personnel up and down during cat ladder accidentally, will fall, can cause the generation of safe falling accident.
Summary of the invention
The purpose of this utility model is to propose a kind of continuous casting rotational flow settling pond construction safety climbing ladder, not only simple and reasonable, easy to make, safe and reliable, and effectively solve the operating personnel and fall because of accidentally dropping during cat ladder up and down and cause the problem of security incident generation.
The purpose of this utility model is achieved like this: a kind of continuous casting rotational flow settling pond construction safety climbing ladder (abbreviation safety climbing ladder), it is characterized in that: the construction of this continuous casting rotational flow settling pond with safety climbing ladder mainly by catladder with protect cage and form, this catladder is comprised of the main vertical rod in front and back and each cross bar, main vertical rod is symmetrical vertical the setting before and after this, the level cross bar that is welded in uniform way from top to bottom between the main vertical rod in front and back, main vertical rod can be made with the angle steel of ∟ 75 * 5 mm specifications before and after this, and each cross bar can be made with the round steel of Ф 20mm, simultaneously, welded and installed is protected cage in the left side of catladder, this protects cage and mainly is comprised of the guard bar of auxiliary pole and each circular arc, in uniform way the front and back end correspondence of each circular arc guard bar is welded in the main vertical rod in front and back of catladder from top to bottom, and the auxiliary pole that vertically is welded at the middle part of each guard bar, assembly welding becomes firmly safety climbing ladder, this guard bar can with wide * thick be that the band steel of 50 * 5mm is made, this auxiliary pole also available wide * thick be that the band steel of 50 * 5mm is made.
During use, from top to bottom pre-buried length * wide * thick is each steel plate built-in fitting of 200 * 200 * 10mm on the pool wall of rotational flow settling pond, horizontal spacing between each built-in fitting is identical with the horizontal spacing of the main vertical rod in front and back of catladder, the vertical spacing of each built-in fitting can be 2000mm, be that the support angle steel of ∟ 75 * 5mm of 500mm firmly welds with the safety cat ladder made and each built-in fitting with length, the operating personnel is not only safety but also can do interim rest during cat ladder up and down, and is safe and reliable.
Safety climbing ladder use in the construction of continuous casting rotational flow settling pond that the utility model proposes, and is not only simple and reasonable, easy to make, safe and reliable, and effectively solved the operating personnel and fall because accidentally dropping during cat ladder up and down and cause the problem of security incident generation.
The continuous casting rotational flow settling pond construction that now in conjunction with the accompanying drawings and embodiments the utility model is proposed is described further with safety climbing ladder.
