The invention provides a ladder and escalator heating device. The ladder and escalator heating device comprises a ladder, an escalator, a first switch, a second switch, a self-temperature-control heating cable, a power supply distribution box, a power supply wiring box and a terminal wiring box, wherein the ladder is vertically mounted on a crane tower body; the escalator is arranged above the ladder in a manner of forming a certain angle with the vertical direction, and the lower part of the escalator is fixedly connected with the upper part of the ladder; the first switch and the second switch are arranged on a power supply wire for connecting the power supply wiring box with the power supply distribution box; the first switch is arranged on one side of the lower part of the ladder; the second switch and the power supply distribution box are arranged in a cab; the self-temperature-control heating cable is distributed in the ladder and the escalator, and is connected with the power supply wiring box; the power supply wiring box is arranged in an armrest on one side of the lower end of the ladder; and the terminal wiring box is arranged in the armrest of the escalator, and is connected with the self-temperature-control heating cable. The ladder and escalator heating device has the characteristics of simple structure, low cost, fast temperature adjusting speed and high energy utilization rate.
Description
technical field [0001] The present invention relates to a heating device, and more particularly to a ladder and escalator heating device for cranes. Background technique [0002] The marine knuckle-arm crane is an important large-scale special mechanical equipment for marine engineering construction and offshore energy development. It is installed on the deck of a special ship through a base. At present, with the continuous expansion of the operating range of marine engineering ships, the working conditions of marine knuckle-boom cranes have become increasingly harsh. When working in extremely low-temperature sea conditions, the surface of the ladder and escalator of the crane will freeze. If the operator wants to enter the driver's cab, he must first pass through the icy ladder and escalator. Due to the freezing, the operator is very likely to have an accident during the climbing process, which poses a threat to personal safety and causes engineering accidents. Therefore,...
