Description
Technical field
The present invention relates to a kind of position indicator, relate to a kind of movement position control setup of insertion plate door or rather.
Background technology
In the solid material process of conveying powdered, granular, block or its mixture, putty phenomenon happens occasionally, particularly in thermal powerplant conveying raw coal process, often run into coal breakage bucket and glue coal, paulin coal, chute blockage, therefore insertion plate door blocks logistics, to facilitate the visual plant of maintenance.In practical application, insertion plate door is an outer closure structure, after plate enters into hopper, be difficult to the particular location observing plate from the outside, clearly can not know the concrete stop position situation after plate insertion, potential safety hazard be existed for normal production, such as, as plate is in half-open position, affect coal to flow through, or Guan Bushang again when needing all to block, do not have the effect of damming, or plate contact is unreal, cause blanking, and is not easy to realize automatically control etc.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and provide a kind of control device for motion position of plug board door, structure is simple, convenient and practical, can know the particular location of plate definitely.
The present invention includes coal bunker, insertion plate door fixed support, hydraulic ram, hydraulic ram is fixed on insertion plate door fixed support by oil cylinder upper bracket, oil cylinder lower bracket, oil cylinder locating plate, the piston rod of hydraulic ram passes insertion plate door fixed support and connects plate, piston rod and the support bracket fastened junction of insertion plate door are provided with sealing arrangement I, it is characterized in that: perforate on insertion plate door fixed support, arrange indicator stem to insert from hole, connect plate by connecting panel, sealing arrangement II is housed between described indicator stem and hole; Between oil cylinder upper bracket, oil cylinder lower bracket, pointer anchor fitting is set, pointer anchor fitting comprises three pipes, be enclosed within oil cylinder upper bracket, oil cylinder lower bracket, indicator stem respectively, the pipe being enclosed within indicator stem connects pointer, oil cylinder lower bracket is fixed left proximity switch, right proximity switch; At plate, block is set away from one end of coal bunker, on insertion plate door fixed support, above plate, positioning plate is set.
Described oil cylinder lower bracket arranges scale, the range ability of display plate, left proximity switch place mark " full cut-off ", right proximity switch place mark " standard-sized sheet ".
As shown from the above technical solution, the present invention utilizes the run location of the perception plates such as left and right proximity switch, indicator stem, plate turnover is driven: indicator stem is advanced and retreated together along with plate by the motion of the piston rod of hydraulic control oil cylinder, pointer is synchronized with the movement along with indicator stem, once in motion is to left proximity switch, namely during full close position, left proximity switch will be responded to, and sends signal, instruction hydraulic efficiency pressure system quits work; When needing to open plate, the reverse fuel feeding of hydraulic ram, piston rod drives plate retraction, and indicator stem, pointer are synchronized with the movement, and once in motion is to right proximity switch, and namely during full open position of coupler, right proximity switch will be responded to, and sends signal, instruction hydraulic efficiency pressure system quits work; Therefore, be convenient to particular location and the running state of understanding plate, be conducive to realizing Automated condtrol; The baffle plate arranged, positioning plate also can control the run location of plate, avoid plate excessively to run.
accompanying drawing illustrates:
Fig. 1 is front view of the present invention.
Fig. 2 is birds-eye view of the present invention.
Fig. 3 is the A-A direction view of Fig. 1.
In figure, 1. coal bunker, 2. insertion plate door fixed support, 3. plate, 4. hydraulic ram, 5. piston rod, 6. sealing arrangement I, 7. oil cylinder upper bracket, 8. oil cylinder lower bracket, 9. oil cylinder locating plate, 10. pointer anchor fitting, 11. pointers, 12. left proximity switches, 13. right proximity switches, 14. indicator stems, 15. connecting panels, 16. sealing arrangement II, 17. blocks, 18. limiting stoppers, 19. scales, 20. pipes.
detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the present invention includes coal bunker 1, insertion plate door fixed support 2, hydraulic ram etc. 4.Hydraulic ram 4 is fixed on insertion plate door fixed support 2 by oil cylinder upper bracket 7, oil cylinder lower bracket 8, oil cylinder locating plate 9, the piston rod 5 of hydraulic ram 4 passes insertion plate door fixed support 2 and connects plate 3, and the junction of piston rod and 5 insertion plate door fixed supports 2 is provided with sealing arrangement I 6.Perforate on insertion plate door fixed support 2, arranges indicator stem 14 and inserts from hole, connects plate 3 by connecting panel 15, between described indicator stem 14 and hole, sealing arrangement II 16 is housed.
Shown in composition graphs 3, between oil cylinder upper bracket 7, oil cylinder lower bracket 8, pointer anchor fitting 10 is set, pointer anchor fitting 10 comprises three pipes 20, be enclosed within oil cylinder upper bracket 7, oil cylinder lower bracket 8, indicator stem 14 respectively, can slide along oil cylinder upper bracket 7, oil cylinder lower bracket 8, indicator stem 14, the pipe 20 being enclosed within indicator stem 14 connects pointer 11, oil cylinder lower bracket 8 is fixed left proximity switch 12, right proximity switch 13, described left proximity switch 12, right proximity switch 13 connecting circuit control setup.Pointer 11 can move between left proximity switch 12, right proximity switch 13.
Shown in composition graphs 2, arrange block 17 at plate 3 away from one end of coal bunker 1, the terminal position that namely plate 3 runs on insertion plate door fixed support 2, above plate 3 arranges positioning plate 18, when plate 3 runs to innermost end, block 17 contacts with positioning plate 18, just can not move again; Once left proximity switch 12, right proximity switch 13 etc. control malfunctioning automatically, the mechanical system that can be contacted with positioning plate 18 by block 17 limits the operation of plate 3.
