Electric building climbing vehicle with compensation function

Abstract

An electric building climbing vehicle with a compensation function comprises a front rotating shaft (1) driven by a motor. Two ends of the front rotating shaft are movably connected with a star-shapedfront wheel carrier (6). A planetary gear (5) and front wheels (7) are integrally formed on the top of the front wheel carrier spoke. The planetary gear is meshed with a sun gear (9) through an intermediate wheel, and the sun gear is fixedly connected with the rotating shaft. A driving sprocket (10) is fixedly connected to the inner side of the front wheel frame. An electromagnetic clutch is arranged between the driving sprocket and the rotating shaft. The rear wheel frame (15) on the rear rotating shaft rotates synchronously with the front wheel frame. The electromagnetic clutch is controlled by a controller, the electromagnetic clutch is controlled by a controller, and the controller comprises a single-chip microcomputer, a rotation angle sensor for detecting the rotation angle of the rear rotating shaft, and a travel switch for judging the size of the staircase. The single-chip microcomputer controls the closure or separation of the electromagnetic clutch according to the rotationangle signal and the travel switch signal so as to roll or translate the wheel frame, thereby realizing the automatic compensation of the staircase, being convenient to use and not easy to wear the staircase.

Description

technical field [0001] The invention relates to a stair climbing device, which is used for transporting goods upstairs. Background technique [0002] The structure of the electric stair climbing vehicle generally includes a rotating shaft, which is driven by a motor, and a wheel frame is installed on the top of the rotating shaft. The wheel frame is composed of multiple spokes, and its shape is star-shaped. When the rotating shaft rotates, the wheel frame rolls on the stairs to realize climbing. Actions. The size of the stairs has a certain range. For example, for a certain staircase, its size is at the lower limit of the range. Each time the wheel frame rotates at a specified angle, the adjacent spokes can rest on the adjacent step plane, but for another For stairs, the size is at the upper limit of the range. For example, the depth of the steps is 300mm (40mm larger than the lower limit). The frame rotates again and can be blocked by the vertical surface of the step, so ...

Problems solved by technology

The size of the stairs has a certain range. For example, for a certain staircase, its size is at the lower limit of the range. Each time the wheel frame rotates at a specified angle, the adjacent spokes can rest on the adjacent step plane, but for another For stairs, the size is at the upper limit of the range. For example, the depth of the steps is 300mm (40mm larger than the lower limit). If the frame rotates again, it will be blocked by the vertical surface of the steps, and the climbing action cannot be completed; in order to solve this problem, the length of the spokes needs to be adjusted according to the specific size of the stairs before use, which brings inconvenience to the use
