Abstract
The invention discloses an anti-impact and anti-extrusion ladder in a hold. A body of the ladder is composed of two opposite support mechanisms and a transverse footboard between the support mechanisms. The V-shaped support mechanisms are fixed onto a wall of the hold, and one lateral edge, connected with the transverse footboard, of each support mechanism is perpendicular to the wall of the hold. The ladder can bear fierce impact and extrusion, requirements for mechanical property are met, stress of a ship structure is even, and local fierce impact is avoided.
Description
Technical field
The present invention relates to a kind of ladder, be specifically related to the ladder of the interior impact resistance of a kind of cargo hold and extruding.
Background technology
Need to arrange the passage up and down for the people in the cargo hold of bulge carrier, this passage is generally taken on by ladder.For saving the space, generally ladder is attached on the bulkhead.In the vertical part, just can satisfy code requirement according to general vertical terraced design standard design, but because the ladder in the cargo cabin of bulk cargo ship places pier section (LOWER STOOL section) at the bottom of the cargo hold transcerse bulkhead, when loading the heavier goods of the larger quality of profile such as ore, often can often be subject to the impact that goods falls; Goods inclines with hull and shakes and can form powerful extruding to ladder when shipping, thus make according to the ladder of production-release design may because of simple in structure, can not to satisfy mechanical property impaired, affects service life.
Summary of the invention
Goal of the invention: the objective of the invention is in order to remedy the deficiencies in the prior art, a kind of ladder that can tolerate intense impact and extruding, satisfy mechanical property requirements is provided.
Technical scheme: impact resistance extruding ladder in a kind of cargo hold, comprise the ladder body, described ladder body is comprised of the horizontal pedal between two relative supporting mechanisms and the supporting mechanism, described supporting mechanism is fixedly installed on hold bulkhead, described supporting mechanism is " V " shape, and a side that connects with the pedal of being connected is perpendicular to hold bulkhead.
As preferably, the angle between described supporting mechanism and the hold bulkhead is 23-27 °.
As preferably, " V " shape bending spring of described supporting mechanism is 40-50 °.
Beneficial effect: the present invention has adopted after such structure, can tolerate strong bump and extruding, and the service life of ladder is longer.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
The specific embodiment
Specific embodiment
Impact resistance extruding ladder in a kind of cargo hold, comprise the ladder body, the ladder body is comprised of the horizontal pedal 2 between two relative supporting mechanisms 1 and the supporting mechanism 1, supporting construction 1 usefulness iron plate is carried out bending, and be fixedly installed on hold bulkhead, supporting mechanism 1 is " V " shape, and a side that connects with the pedal of being connected 2 is perpendicular to hold bulkhead, angle between supporting mechanism 1 and the hold bulkhead is 23-27 °, and " V " shape bending spring of supporting mechanism 1 is 40-50 °.
Substitute ladder both sides frame (65 * 9～band steel) and feet (65 * 12～band steel) with curved plates, so that former impulsive force and the squeese pressure that concentrates on the supported on both sides pin is distributed to whole curved plates effectively, the requirement that not only makes ladder satisfy mechanics and use is also so that the hull structure uniform stressed, avoid local powerful the impact.The thickness of steel plate generally between 10-16mm, is decided on actual loading intensity, is subjected to that position and description of cargo affect in cargo hold, and the cargo hold depth is larger, and the present position is the closer to the bottom, and is stressed stronger, and required steel plate is thicker; Different goods such as iron ore and cereal, because density is different, for onesize cargo hold, the ladder of same position is subjected to the force intensity also can be different, required steel plate thickness also needs different.
Claims (3)
