The technical scheme is convenient for workers to go up and down the ship body and work high above the ground, and has high safety.
Preferably, the inclined ladder includes the inclined ladder frame, and the inside equidistance of inclined ladder frame sets up the footboard that the level was arranged, the footboard adopts anti-skidding steel sheet preparation. The steps made of the antiskid steel plates prevent feet of workers from skidding when the workers walk on the inclined ladder.
Preferably, the first frame is provided with diagonal braces. The diagonal stay improves the strength of the first frame.
Preferably, the second frame is provided with a second cross brace. The second traverse bar improves the strength of the second frame.
Preferably, the bottom of the first frame is provided with a universal wheel with a lock. The universal wheel with the lock increases the maneuverability of the step ladder.
Compared with the prior art, the utility model, have following advantage:
1. the inclined ladder, the first platform, the straight ladder and the second platform form a channel which is convenient for workers to get on and off the ship body, and the handrail on the inclined ladder, the first steel plate net at the first platform and the second steel plate net at the second platform improve the safety of the channel.
2. The inclined ladder footboard adopts the preparation of anti-skidding steel sheet, and first platform is provided with first steel sheet net, and the second platform is provided with the second steel sheet net, has increased the frictional force of staff foot, avoids skidding.
3. When the worker is on the first platform, the worker can operate at a height of 2m-4m relative to the bottom of the first frame, and the safety of the worker during operation is improved by the first steel plate net and the first guardrail on the first platform; when the staff is at the second platform, the staff can carry out the operation of 4m-6m height relative to the bottom of the first frame, and the second steel plate net and the second guardrail at the second platform improve the safety of the staff during operation.
4. The universal wheel with the lock increases the maneuverability of the step ladder.
