Utility model content
In order to solve the above-mentioned problems in the prior art, this utility model provides a kind of coal pulverizer deslagging pneumatic door position limiting structure.
For achieving the above object, this utility model takes technical scheme: a kind of coal pulverizer deslagging pneumatic door position limiting structure, including the slag bucket plate at ash gate with to the cylinder-driven bar of slag bucket plate offer power, the piston end at cylinder-driven bar top is positioned at cylinder, cylinder-driven bar end is fixed on the middle part of slag bucket plate, also include that the length being located at outside cylinder gathers bar more than the cylinder-driven of cylinder-driven bar, cylinder-driven gathers bar and parallels setting with cylinder-driven bar, cylinder-driven gathers the end of bar and the end Joint of cylinder-driven bar, cylinder-driven gathers the top affixed limit induction baffle plate of bar；Between the top of cylinder to end, a stationary backplate is set on the horizontal direction of cylinder outer wall, stationary backplate is positioned at cylinder-driven and gathers the lower section of bar, stationary backplate is provided with near the one end at cylinder top and controls the first sensing limit switch that deslagging pneumatic door is closed, stationary backplate is provided with near one end of cylinder end and controls the second sensing limit switch that deslagging pneumatic door is opened, and limit induction baffle plate is movable between two sensing limit switches between two sensing limit switches.
Further, the end of cylinder-driven bar is provided with movable block, and movable block is fixed on the middle part of slag bucket plate.
Further, being provided with track below cylinder-driven bar, the bottom of movable block is positioned on described track.
The beneficial effects of the utility model are:This utility model include cylinder-driven gather bar, limit induction baffle plate, sense spacing.The mechanical driving lever of former deslagging pneumatic door is transform as transmission and gathers bar, at extension to cylinder；Change into mechanical position limitation sensing limit switch.This structure solves coal pulverizer deslagging pneumatic door close to slag bucket thermal source, and pneumatic door door-plate temperature is high, easily causes mechanical position limitation inner contact and cabinet deformed damaged, the spacing problem often being offset from of pneumatic door.Use transmission to gather bar and sensing limit switch, away from slag bucket thermal source, the spacing registration of pneumatic door, open and close flexible operation, do not have machinery bite, switch phenomenon not in place, it is simple to repair and maintenance and operation.This structure is applicable to the use of coal pulverizer deslagging pneumatic door.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing thereof, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Figure 1, a kind of coal pulverizer deslagging pneumatic door position limiting structure, including the slag bucket plate at ash gate with to the cylinder-driven bar of slag bucket plate offer power, the piston end at cylinder-driven bar top is positioned at cylinder, cylinder-driven bar end is fixed on the middle part of slag bucket plate, also include that the length being located at outside cylinder gathers bar 1 more than the cylinder-driven of cylinder-driven bar 7, cylinder-driven gathers bar 1 and parallels setting with cylinder-driven bar 7, cylinder-driven gathers the end of bar 1 and the end Joint of cylinder-driven bar 7, and cylinder-driven gathers the top affixed limit induction baffle plate 2 of bar 1；Between the top of cylinder to end, a stationary backplate 4 is set on the horizontal direction of cylinder outer wall, stationary backplate 4 is positioned at cylinder-driven and gathers the lower section of bar 1, stationary backplate 4 is provided with near the one end at cylinder top and controls the first sensing limit switch 31 that deslagging pneumatic door is closed, stationary backplate 4 is provided with near one end of cylinder end and controls the second sensing limit switch 32 that deslagging pneumatic door is opened, and limit induction baffle plate 2 is between two sensing limit switches.Two sensing limit switches are located at ash gate and are controlled to control the "ON" of ash gate, "Off" respectively in loop.The end of cylinder-driven bar 7 is provided with movable block, and movable block is fixed on the middle part of slag bucket plate.Being provided with track below cylinder-driven bar 7, the bottom of movable block is positioned on described track 8.
In the stationary backplate 4 of cylinder 6 extenal fixation strip, the sensing limit switch of coal pulverizer deslagging pneumatic door is respectively adopted 16 screws and is fixed in the two ends of stationary backplate.The end that cylinder-driven gathers bar 1 is fixed on ash gate cylinder-driven bar 7, Threaded Connector Coupling fastening in vertical welding 32, and cylinder-driven collection bar 1 lengthens 60cm and is extended down to ash gate cylinder body outer wall top, carries out the stroke collection of ash gate open and close position.Two sensing limit switch distance slag bucket more than plate 60cm, can prevent cable, control the bright boiling hot scaling loss of position switch.
