Steel ball free-rolling-down type electronic gradient measurer

Abstract

The invention relates to a measuring apparatus, in particularly to a steel ball free-rolling-down type electronic gradient measurer which mainly comprises a rolling path, an upper end, a lower end, a steel ball, a liquid crystal display, a micro electromagnet, a travel switch, a control cabinet, and the like. When the measurement begins, the switch of the steel ball free-rolling-down type electronic gradient measurer is pressed down, a control button of the micro electromagnet is then pressed down, the micro electromagnet is pulled in at the moment to loosen the blocked steel ball, the steel ball begins to roll downwards from the static state along the rolling path, and meanwhile, a timer in the control cabinet begins timing; the steel ball continuously rolls downwards faster and faster until stopping when touching the lower end, at the moment, the steel ball presses the travel switch to enable the timer to stop timing, and a numerical value of the measured gradient is displayed on the liquid crystal display through the operation of a microprocessor in the control cabinet.

Description

Technical field [0001] The invention relates to measuring equipment, in particular to a free-rolling type of steel ball which can be used to measure the slope conveniently and accurately when a steel ball rolls down from a smooth raceway of a certain length, the movement time of which has a certain relationship with the inclination of the raceway Electronic slope measuring instrument. Background technique [0002] In engineering, we often need to measure slope, but the current slope measuring instruments on the market either have low measurement accuracy, or the measurement process and calculation are cumbersome, and there is no ideal product that can meet this demand for engineering measurement. Summary of the invention [0003] In order to solve this problem, the present invention provides a free-rolling electronic slope measuring instrument for steel balls, which allows users to measure slope conveniently and accurately. [0004] The technical scheme adopted by the present inven...
