Abstract

A slope-adjustable slope experimental device comprises a control mechanism, a slope surface workbench and a slope adjusting mechanism. The control mechanism is composed of a controller, a control system and a stepper motor drive system. The slope surface workbench comprises a surface plate and two sloping plates. The slope adjusting mechanism comprises a bottom groove, tooth-like tracks, a gear and a sliding block mechanism. The bottom groove is provided with a support pillar for supporting the surface plate, and a boss is arranged in the bottom groove. There are two tooth-like tracks which are parallelly arranged up and down in the length direction of the bottom groove, wherein one of the tracks is slidingly arranged on the boss. The gear is arranged between the two tooth-like tracks and is driven by a stepper motor in the stepper motor drive system after engaged with the two tooth-like tracks. The sliding block mechanism is composed of a sliding block and a chute which is arranged on the sloping plate and used for letting the sliding block slide. The sliding block is movably connected to one end of the corresponding tooth-like track. The device provided by the invention has an elaborate structure, is convenient to operate, has high angle adjustment accuracy and is especially applicable to slope experiments, in which height of a slope surface is required to be unchanged.

Description

technical field [0001] The invention belongs to the field of mechanical automatic control, in particular to an experimental device with adjustable slope. Background technique [0002] At present, in researching slope experiments such as goat climbing, there is a lack of an experimental device that can adjust the slope arbitrarily. [0003] The stepper motor is an open-loop control element stepper motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load change. When the stepper driver receives a pulse signal, it will drive the stepper motor to press The set direction rotates a fixed angle, which is called "step angle", and its rotation runs step by step at a fixed angle. Therefore, the angular displacement can be controlled by controlling the number of pulses, so as...
