External electromechanical floor lifting step

Abstract

The invention provides an external electromechanical floor lifting step. C-shaped rails are laid along the two sides of a stair, openings of the left rail and the right rail correspond to each other, two rail wheels are arranged in each of the left rail and the right rail, spindles of the rail wheels are fixed to the two sides of the step and mainly bear the step to slide up and down in the rails, and handrails are arranged at the upper ends of the two sides of the step. An intelligent box and a lifting switch are installed at the upper ends of the handrails, U-shaped wheels are installed on the left side, on the right side and in the middle of the step, a motor is arranged in an accessory box of a wall surface above the stair, an intelligent alarm and a fire extinguisher are additionally installed in the accessory box, a roller is installed at the front end of the motor and connected with a steel wire rope, the steel wire rope extends in the left rail through a guide wheel and is inserted into grooves of left U-shaped wheel, the middle U-shaped wheel and the right U-shaped wheel, and the three U-shaped wheels are in an inverted triangle shape. Balance and stability of the step can be kept during up and down sliding, the tail end of the steel wire rope is connected to a fixing pin at the top end of the right rail, remote control switches are correspondingly installed on the wall faces above and below the stair, and the whole up-down sliding process of the step is completed by driving the roller to drag the steel wire rope through the motor and under supporting of two rail wheels.

Description

technical field [0001] The invention relates to a floor lifting step, in particular to an external electromechanical floor lifting step Background technique [0002] Recently, in response to the country's call for installing elevators in old urban communities, I invented a double-track floor elevator (application number 201920836950.6). The track is equipped with steps in the middle. At the same time, safety measures such as double-sided handrails and folding tables and chairs are added to the steps. The dual-track synchronous operation mode can easily carry two to three people (including children) and simple load crawling. However, this invention has a major defect: the most important electromechanical control system is assembled in the narrow space below the steps, and the thicker anti-skid steel plate is used above the steps. The screws are tightly closed. Under normal circumstances, it is impossible to open without professionals and professional tools. Therefore, in add...

The screws are tightly closed. Under normal circumstances, it is impossible to open without professionals and professional tools. Therefore, in addition to the difficulty of maintenance, once it is used for a long time, it is difficult to extinguish the leakage and fire caused by the aging of the motor or power supply, which will cause serious damage to residents. cause serious injury and loss
