Abstract
The invention discloses a coal mill water resistor polar plate guide structure. The coal mill water resistor polar plate guide structure comprises a polar plate, guide rails, a movable rod and a first limit switch, wherein the polar plate, the guide rails, the movable rod and the first limit switch are arranged in a water resistor cabinet; the guide rails are located on the two sides of the polar plate; the two sides of the polar plate are provided with sliding grooves which are in sliding fit with the guide rails correspondingly; the movable rod is mounted in the center of the top surface of the polar plate; and the first limit switch is mounted at the top end of one guide rail. According to the coal mill water resistor polar plate guide structure, the polar plate is limited to be prevented from damaging the water resistor cabinet in the rising process, so that production accidents are avoided.
Description
Technical field
The present invention relates to coal dust and produce equipment technical field, especially coal mill water resistance pole plate guide frame.
Background technology
After coal mill water resistance start, pole plate is during dropping to rising, it is from certain build-up lag, if pole plate of leaving rises under effect of inertia, will cause pole plate bursting water resistance cabinet end face, cause damage, and traditional guide frame is difficult to avoid that the generation of problems.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose coal mill water resistance pole plate guide frame, by spacing to this, it is to avoid pole plate damages water resistance cabinet in uphill process, the method that thus avoid production accident is raw.
In order to realize foregoing invention purpose, the present invention provides techniques below scheme:
Coal mill water resistance pole plate guide frame, including the pole plate being arranged in water resistance cabinet, guide rail, motion bar and the first limit switch,
Described guide rail is positioned at described pole plate both sides, is respectively provided on two sides with chute at described pole plate, and described chute coordinates with described slide,
Described motion bar is arranged on described pole plate end face center,
Described first limit switch is arranged on described guide rail top.
Further, also include the second limit switch, described second limit switch be arranged on on the guide rail of described first limit switch opposite side.
Further, described second limit switch is positioned at the top of described first limit switch.
Further, described second limit switch is positioned at above described first limit switch at 5mm, and distance water resistance cabinet end face certain distance.
Coal of the present invention mill water resistance pole plate guide frame, by spacing to this, it is to avoid pole plate damages water resistance cabinet in uphill process, the method that thus avoid production accident is raw.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of coal of the present invention mill water resistance pole plate guide frame.
Detailed description of the invention
Describing the present invention below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, should not have any restriction effect to protection scope of the present invention.
Coal mill water resistance pole plate guide frame as shown in Figure 1, including the pole plate 5 being arranged in water resistance cabinet, guide rail 4, motion bar 2 and the first limit switch 3,
Described guide rail 4 is positioned at described pole plate 5 both sides, is respectively provided on two sides with chute at described pole plate 5, and described chute is slidably matched with described guide rail 4,
Described motion bar 2 is arranged on described pole plate 5 end face center,
Described first limit switch 3 is arranged on described guide rail top.
Also include the second limit switch 1, described second limit switch 1 be arranged on on the guide rail 4 of described first limit switch 3 opposite side.
Described second limit switch 1 is positioned at the top of described first limit switch 3.
Described second limit switch 1 is positioned at above described first limit switch 3 at 5mm, and distance water resistance cabinet end face certain distance.
During use, pole plate 5 is in uphill process, its top still can rise after touching the first limit switch 3 under effect of inertia, now, the first limit switch 3 can be the most touched, causes this motor the most out of service again to run, band movable plate electrode 5 continues to rise, for avoiding motion bar 2 bursting water resistance cabinet end face, installing the second limit switch 1, pole plate 5 stops when touching the second limit switch 1 rising.
Coal of the present invention mill water resistance pole plate guide frame, by spacing to this, it is to avoid pole plate damages water resistance cabinet in uphill process, the method that thus avoid production accident is raw.
