Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment one (grease gun igniting rifle opening direction is contrary with the direction that expansion link stretches out cylinder).
The signal feedback device of boiler oil gun burning torch propelling stroke as shown in Figure 1, comprise the grease gun igniting rifle 20 being driven to pass in and out boiler by the expansion link 11 of cylinder 10, the stiff end of grease gun igniting rifle 20 of the present utility model is fixed on the top 110 of expansion link 11 by a connection piece 30, grease gun igniting rifle 20 is parallel with expansion link 11, and opening 201 direction of grease gun igniting rifle 20 is contrary with the direction that expansion link 11 stretches out cylinder 10; Install a strong magnet 40 at cylinder 10 end winding support, an in parallel and support 50 be synchronized with the movement is fixed at the top 110 of the expansion link 11 of cylinder 10, and on support 50, the stretch two ends of stroke of corresponding expansion link 11 fixedly mount a magnetic switch 60 respectively; Each magnetic switch 60 is connected with DCS control centre 90 respectively by the wire 70 being connected with three anti-master-slave sockets 80; Any one magnetic switch 60 produces a signal of telecommunication and feeds back to DCS control centre 90 to determine the propelling position of grease gun igniting rifle 20 when sensing strong magnet 40 magnetic field.
The following detailed description of operation principle of the present utility model with specifically implement action.
As shown in Figure 1, when the expansion link 11 of cylinder 10 stretches out and drives grease gun igniting rifle 20 to exit boiler furnace wall 120, support 50 and on two magnetic switch 60 along with the synchronous displacement to the right of expansion link 11, the magnetic switch 60 of support 50 upper left side senses strong magnet 40 magnetic field and produces a signal of telecommunication, this signal of telecommunication is fed back in time by the wire 70 of the three anti-master-slave sockets 80 be connected with and sends DCS control centre 90 to, to determine that grease gun igniting rifle 20 exits the position of boiler furnace; Even if grease gun igniting rifle 20 is when 1 ~ 3cm place that distance expansion link 11 stretches out end of travel produces slight bite phenomenon, respond to strong magnet 40 magnetic field fast due to magnetic switch 60 and the signal of telecommunication produced is fed back to DCS control centre 90, grease gun igniting rifle 20 can not be caused to exit the signal hysteresis of burner hearth position, and the signal of feedback is more reliable.
Expansion link 11 indentation of cylinder 10 drives grease gun igniting rifle 20 to enter boiler furnace wall 120, support 50 and on two magnetic switch 60 along with expansion link 11 synchronous to left dislocation, on support 50, the magnetic switch 60 on right side senses strong magnet 40 magnetic field and produces a signal of telecommunication, this signal of telecommunication is fed back in time by the wire 70 of the three anti-master-slave sockets 80 be connected with and sends DCS control centre 90 to, to determine that grease gun igniting rifle 20 enters the position of boiler furnace; Even if when grease gun igniting rifle 20 produces slight bite phenomenon at 1 ~ 3cm place of distance expansion link 11 indentation end of travel, respond to strong magnet 40 magnetic field fast due to magnetic switch 60 and the signal of telecommunication produced is fed back to DCS control centre 90, grease gun igniting rifle 20 can not be caused to enter the signal hysteresis of burner hearth position.
The three anti-master-slave sockets 80 that the utility model passes through plug dismounting because of magnetic switch 60 connect, therefore maintenance magnetic switch 60 is replaced more convenient, the detection that whether magnetic switch 60 damages simultaneously directly can be tested by a small magnet in uncharged situation, and the installation site of two magnetic switch 60 and strong magnet 40 can adjust flexibly.
Embodiment two (grease gun igniting rifle opening direction is identical with the direction that expansion link stretches out cylinder).
As shown in Figure 2, the present embodiment is with the difference of embodiment one: the direction that opening 201 direction of grease gun igniting rifle 20 and expansion link 11 stretch out cylinder 10 is identical, other structure of the present embodiment and operation principle are with embodiment one, expansion link 11 indentation that design like this can realize cylinder 10 drives grease gun igniting rifle 20 to exit boiler furnace wall 120, and expansion link 11 stretches out and drives grease gun igniting rifle 20 to enter boiler furnace wall 120.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, those skilled in the art, when not departing from spirit and scope of the present utility model, can also make various conversion or change.Therefore, all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
