Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
This utility model is a kind of motor speed measuring device test platform for electronic weighing type coal feeder, and as Figure 2-Figure 5, it includes measure speed gears, by key, motor 8 is connected with measure speed gears, and motor 8 is extension shaft motor, as shown in Figure 2.Measure speed gears arranged above with fan blade 3, between measure speed gears and fan blade 3 by jump ring spacing.The surrounding of measure speed gears is evenly distributed with the support being fixed on motor 8, and the height of each support is all different.Each support is provided with a holes probe, and holes probe is threadedly secured on support by what coordinate on each support, and is concentrated on by cable in terminal block fixing.Holes probe is that the plug-in type being connected with CPU quickly switches probe.The waveform transfer detected by holes probe is to coal feeder control system CPU.The quantity of measure speed gears, support quantity all identical with the quantity of holes probe.Measure speed gears is provided with 2-10, and is different size.
The end overlapping measure speed gears more and being installed on extension shaft motor is installed concentratedly by this utility model, save the experiment number of motors that coal feeder control system verification is required, have only to a set of speed measuring device test platform, separate, from the plug-in type of cable terminal, the switching can being easily accomplished between different measure speed gears by connecting terminal block.Without being equipped with the motor of multiple stage difference measure speed gears simultaneously, it is greatly saved experimentation cost.This utility model overlaps speed measuring device because it can be equipped with on a motor simultaneously more simultaneously, can switch to another set of speed measuring device automatically by control system when a set of speed measuring device breaks down, it is not necessary to maintainer is exchange device more.Its practicality and reliability make it can directly apply to on-the-spot used device production.
The present embodiment has 4 measure speed gearses (i.e. first gear the 4, second gear the 5, the 3rd gear the 6, the 4th gear 7).
