Escalator for ship

Abstract

The invention relates to an escalator for a ship. The escalator is characterized in that an underlying machine room is adopted, a drive tractor is fixedly arranged on the lower part of an upper horizontal section of a truss, and a main drive chain of a drive system is provided with a tension deviation prevention device; a transverse profile of the truss is provided with an emergency guide rail, two guide rail supporting plates are respectively provided with a return-side auxiliary wheel press rail and a return-side main wheel press rail; an electrical system is provided with an inclination angle sensor, an automatic heating loop and an automatic air exhaust loop, so that the escalator for the ship can satisfy the application characteristics on the ship. Not only can the normal running of a transmission chain be guaranteed, but also the danger of the transmission chain in a shaking environment can be prevented; meanwhile, the running range of a stepped chain wheel and a stepped auxiliary wheel can be limited, and the salt corrosion problem of the escalator when used on a large-sized ship can be solved.

Description

technical field [0001] The invention relates to a conveyor, in particular to a marine escalator. Background technique [0002] In recent years, the speed of my country's shipbuilding industry has continued to grow. With the steady improvement of social living conditions, the desire of passengers to pursue a comfortable living environment has gradually become stronger, and the demand for installing marine escalators on large and medium-sized ships has become increasingly strong, and the market prospect is broad. Compared with the shipbuilding industry of western developed countries, the localization level of my country's marine supporting equipment is relatively low. Therefore, increasing the share of domestic marine equipment is an inevitable trend for the sustainable development of the national shipbuilding industry. Compared with land escalators, the demand for marine escalators is relatively small and has industry characteristics, so it has not attracted enough attentio...

Problems solved by technology

In addition, conventional escalators installed on land will not shake under normal circumstances, but due to environmental conditions, the ship will shake at ±10° in the horizontal direction, with a period of 10s, and ±7.5° in the vertical direction, with a period of 7s. In the operating environment, due to the chain drive itself, the stability of the transmission chain in the main drive system of the escalator cannot be guaranteed at all times. At the same time, the operation of the escalator under this shaking condition will lead to unstable operation of the ladder road, and the occurrence of step sprockets Or the case where the step wheel slips out of the track
