Description
Technical Field
The utility model relates to the technical field of ship lifts, in particular to a ship lift ship-receiving box escape ladder structure driven by a spiral lifting mechanism.
Background
When the ship lift ship receiving box is stopped at different heights, the deck of the ship receiving box is not exactly aligned with the ground of the escape door on the tower column, so that an escape ladder capable of being lifted is needed to connect the deck with the escape door, thereby facilitating daily passing and emergency evacuation of personnel.
The existing ship-receiving compartment escape ladder is generally provided with a top pedal, the top pedal can move up and down along the guide mechanisms on the two support columns, the inclined ladder steps below are installed in a rectangular frame which is obliquely placed through respective rotating shafts, one end of the frame is connected with the top pedal, and the other end of the frame is provided with rollers which can slide in a chute on the ground. The stair steps are connected with the top pedal through the connecting rod mechanism, so that the stair steps can always be kept horizontal when the top pedal drives one end of the rectangular frame to move up and down.
The top pedal of the escape ladder is driven to lift by adopting chain transmission, a hanging shaft is arranged on the top pedal, a chain is arranged at the end part of the hanging shaft, the chain upwards bypasses a fixed pulley chain wheel at the top of the supporting column, then downwards bypasses a chain wheel on the transmission shaft, and finally upwards is connected with the hanging shaft again. The motor drives the chain wheel on the transmission shaft to rotate through the speed reducing mechanism, so that the top pedal can be driven to move up and down, and the escape ladder can be lifted. The hanging shaft of the top pedal is generally directly installed in the guide grooves of the two support columns, and the hanging shaft and the guide grooves have smaller gap in design, so that the hanging shaft can play a role in guiding the ascending and descending of the escape ladder. However, after the escape ladder runs for a long time, a larger gap is formed between the hanging shaft and the guide groove due to abrasion, so that the upper pedal and the lower pedal of personnel are obviously rocked, shake and abnormal sound can be generated due to unsmooth guiding at two sides when the escape ladder is lifted, and a transmission shaft or a chain is broken when serious, so that a safety accident is caused. Worn hanging shafts can be replaced generally, but the guide grooves are not convenient to replace directly because the guide grooves are machined on the support column body, so that the problem is difficult to treat thoroughly.
In addition, in order to prevent the interference between the top pedal and the tower wall, a certain gap is generally left between the top pedal and the tower wall in consideration of the possibility of a certain degree of lateral movement of the ship receiving chamber. However, the existence of the gap brings the risk of stepping on the sky for the passage of people.
