Description

Anti-skid inclined ladder

Technical Field

The invention relates to the technical field of ships, in particular to an anti-skid inclined ladder.

Background

The inclined ladder is equipment for assisting a shipman to reach a certain position and height, the existing ship inclined ladder generally adopts a pressure welding steel grating step, but the inclined ladder is installed in a cabin folding stage after prefabrication is completed, at the moment, a pedal can be inclined downwards due to the error of an installation angle, and the gravity center is vertical to feet in the process of ascending and descending the ladder by the shipman, so that the gravity center can incline downwards along with the gravity center, and the gravity center of the shipman is unstable and slides down when ascending and descending the inclined ladder; meanwhile, when the ship runs on the sea, the stairs are very easy to wet, the environment of the ship cabin is complex, oil stains are common on the stairs, and the risk of slipping is caused easily by crews. Therefore, there is an urgent need for an anti-slip ramp that avoids a crew from slipping down in the event of a wet and leaning ramp.

Optionally, the pedal is a steel grid pedal.

Optionally, the ladder frame further comprises an upper eye plate and a lower eye plate, wherein the upper eye plate and the lower eye plate are respectively connected with two ends of the fixing plate and used for fixing the ladder frame.

Optionally, the dustproof piece is a dustproof plate, and the dustproof piece is connected with the fixed plate.

Optionally, the device further comprises an upper strut, wherein one end of the upper strut is connected with the upper eye plate, and the other end of the upper strut is connected with the armrest.

Optionally, the handrail is provided with a fixed block, and the handrail is connected with the ladder frame through the fixed block.

Optionally, the triangular anti-slip strip is connected with the pedal by welding or bolts.

Optionally, the dust guard is connected with the ladder frame by bolts.

The beneficial effects of the invention are as follows:

during the process of ascending and descending the ladder by the crewman, the gravity center is vertical to the feet, on one hand, if the pedal installation angle of the ladder is inclined, the gravity center of the crewman is inclined; on the other hand, when oil stains or water stains exist on the ladder, the friction force between the pedal and the foot of a shipman is extremely small, and the ladder is easy to slip. By arranging the triangular anti-slip strips at the edges of the pedals, when a shipman walks up and down stairs normally, shoes can be clamped on the triangular anti-slip strips, and certain resistance is formed on the shoes; meanwhile, the gravity center of the front sole is inclined forwards, and the gravity center of the shipman body is inclined backwards after the front sole is supported, so that the occurrence of slipping accidents caused by downward inclination of pedals can be prevented when the shipman goes up and down stairs, and the safety of the shipman is improved.
