Abstract
The invention discloses a control device for the motion position of a plug board door. The control device solves the problem that the specific position of a plug board cannot be obtained by an existing device. The control device is characterized in that an indicating rod is arranged to penetrate through a plug board door fixing support and be connected with the plug board, an indicator fixing device comprising three circular pipes is arranged between an upper oil cylinder support and a lower oil cylinder support, the upper oil cylinder support, the lower oil cylinder support and the indicating rod are sleeved with the three circular pipes respectively, an indicator is connected to the circular pipe which the indicating rod is sleeved with, a left proximity switch and a right proximity switch are fixed to the lower oil cylinder support, a stopping block is arranged at one end, away from a coal bucket, of the plug board, and a limiting board is arranged at the portion, above the plug board, on the plug board door fixing support. According to the control device for the control position of the plug board door, the left proximity switch, the right proximity switch, the indicating rod and the like are utilized for sensing the running position of the plug board, a piston rod of a hydraulic oil cylinder is controlled to move to drive the plug board to get in and out, the specific position and the running status of the plug board are conveniently known, and the automation control is facilitated; the arranged stopping block and limiting board can also control the running position of the plug board, and excessive running of the plug board is avoided.
Description
Technical field
The present invention relates to a kind of position indicator, relate to or rather a kind of movement position control setup of insertion plate door.
Background technology
In the solid material process of conveying powdered, granular, block or its mixture, putty phenomenon happens occasionally, particularly at thermal powerplant, carry and in raw coal process, often to run into the sticky coal of coal breakage bucket, paulin coal, chute blockage, thus insertion plate door be to logistics block, to facilitate the visual plant of maintenance.In practical application, insertion plate door is an outer closure structure, because plate enters into after hopper, be difficult to from the outside observe the particular location of plate, can not clearly know the concrete stop position situation after plate inserts, for normal production, have potential safety hazard, such as, as plate is in half-open position, affect coal stream and pass through, or Guan Bushang again need to all block time, do not have the effect of damming, or plate contact is unreal, cause blanking, and is not easy to realize automatic control etc.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art provides a kind of insertion plate door movement position control setup, simple in structure, convenient and practical, can know definitely the particular location of plate.
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 is through insertion plate door fixed support and connect plate, the support bracket fastened junction of piston rod and insertion plate door is provided with sealing arrangement I, it is characterized in that: perforate on insertion plate door fixed support, indicator stem is set and from hole, inserts, by connecting panel, connect plate, 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 respectively on oil cylinder upper bracket, oil cylinder lower bracket, indicator stem, connect pointer being enclosed within on the pipe of indicator stem, on oil cylinder lower bracket, fix left approach switch, right approach switch; At plate, away from one end of coal bunker, block is set, on insertion plate door fixed support, plate above positioning plate is set.
On described oil cylinder lower bracket, scale is set, shows the range ability of plate, at left approach switch place mark " full cut-off ", at right approach 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 approach switch, indicator stem, by controlling the motion of the piston rod of hydraulic ram, drive plate to pass in and out: indicator stem is along with plate is advanced and retreated together, pointer is along with indicator stem is synchronized with the movement, once in motion is to left approach switch, while being full close position, left approach switch will be responded to, and sends signal, instruction hydraulic efficiency pressure system quits work; In the time of need to opening 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 approach switch, and during full open position of coupler, right approach switch will be responded to, and sends signal, instruction hydraulic efficiency pressure system quits work; Therefore, be convenient to understand particular location and the running state of plate, be conducive to realize automation and control; The baffle plate, the positioning plate that arrange also can be controlled the run location of plate, avoid plate excessively to move.
accompanying drawing explanation:
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 approach switchs, 13. right approach switchs, 14. indicator stems, 15. connecting panels, 16. sealing arrangement II, 17. blocks, 18. limiting stoppers, 19. scales, 20. pipes.
the specific embodiment:
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 is through insertion plate door fixed support 2 and connect 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 from hole, inserts, by connecting panel 15, connects plate 3, between described indicator stem 14 and hole, sealing arrangement II 16 is housed.
Shown in Fig. 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 respectively on oil cylinder upper bracket 7, oil cylinder lower bracket 8, indicator stem 14, can slide along oil cylinder upper bracket 7, oil cylinder lower bracket 8, indicator stem 14, connect pointer 11 being enclosed within on the pipe 20 of indicator stem 14, on oil cylinder lower bracket 8, fix left approach switch 12, right approach switch 13, described left approach switch 12, right approach switch 13 connecting circuit control setups.Pointer 11 can move between left approach switch 12, right approach switch 13.
