Background
For a tamping coke oven, in the process of charging coal of the coke oven, a coal dragging bottom plate brings coal cakes from a side oven door of the coke oven to a coke side of a carbonization chamber, if the coal dragging bottom plate is too close to the coke side when advancing, the coal dragging bottom plate possibly pushes a door lining brick at the coke side, and in severe cases, the oven door can be pushed out to cause accidents; if the front limit distance of the coal dragging bottom plate is too large, namely the distance of the coke-side coal cake from the coke-side furnace door is too far, the temperature of the coke-side furnace of the carbonization chamber is possibly too high, and high-temperature accidents and the like are caused.
The traditional method for determining the operation front limit of the coal dragging bottom plate is that the coke side furnace door is taken to enable the coal car coal dragging bottom plate to penetrate into the carbonization chamber to determine the coal dragging bottom plate front limit, the coal car coal dragging bottom plate is difficult to implement under the condition that the coal car coal dragging bottom plate is baked at the temperature of about 1000 ℃ in the hearth of the carbonization chamber, measurement is inaccurate, time and labor are wasted, normal production of the coke furnace is affected, and safety problems of personnel scalding are easily caused.

In the figure: 1-a laser emitter; 2-a graduated scale; 3-coke side oven door; 4-a coal dragging bottom plate experiment platform; 5-dragging a coal bottom plate; 6-furnace group.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, a plurality of carbonization chambers are arranged side by side to form a furnace group 6, and a coal dragging bottom plate experiment platform 4 is arranged at one end of the furnace group 6. The method can be used for confirming the front limit position of the coal dragging bottom plate 5 in each carbonization chamber at any time in the production process. In fig. 1, the upper part of the oven group 6 is the coke oven side, and the lower part is the coke oven side.
A. A laser emitter 1 is arranged on a coke side furnace door 3; a graduated scale 2 is arranged on the coke side of a coal dragging bottom plate experiment platform 4 of the coke oven end table; a displacement sensor is arranged on the coal dragging bottom plate 5, and the displacement sensor is connected with a driving motor of the coal dragging bottom plate 5;
B. turning on the laser emitter 1, emitting a laser column in a direction parallel to the furnace group 6 (namely, perpendicular to the longitudinal direction of the carbonization chamber) and shooting the laser column to the graduated scale 2, and recording the position A of the laser column shot on the graduated scale 2;
C. measuring the vertical distance length a of the emission point of the installed laser emitter 1 from the lining brick of the coke side furnace door 3; according to production practice, determining the distance length b from the coal dragging bottom plate 5 to the lining brick of the coke side furnace door 3 after entering the carbonization chamber, wherein b is determined to be 50mm;
D. b, finding a position with a distance a+b from the position A to the machine side direction according to the position A of the laser column shot on the graduated scale 2 recorded in the step A on the coal dragging bottom plate experiment platform 4, wherein the position is marked as a point B, and the point B is the front limit position of the coal dragging bottom plate 5;
E. and (D) aligning the front end of the coal dragging bottom plate 5 to the machine side end of the coal dragging bottom plate experiment platform 4, manually sending out the coal dragging bottom plate 5 to the position point B found in the step (D), setting the moving distance on a displacement sensor, and controlling a driving motor of the coal dragging bottom plate 5 to be closed by the displacement sensor when the coal dragging bottom plate 5 moves forward to the set distance.
When the laser transmitters 1 are mounted on different coke oven doors 3, the positions should be chosen to be the same and fixed position for each coke oven door 3. The laser emitter 1 is preferably a laser emitter with a buckle or adsorptivity, and is convenient to place and take down. The laser emitted by the laser emitter 1 is a red or green visible light beam, the beam spot is small enough, the laser is emitted in a straight line, the position is accurate, and the laser cannot be changed due to environmental change.
When the vertical distance a between the emission point of the installed laser emitter 1 and the lining brick of the coke oven door 3 is measured, the same type of the coke oven door can be carried out on the standby oven door; and the distance a is very little changed for different furnace doors of the same coke furnace, and can be ignored, namely, the distance a takes the same value when the front limit position of the coal dragging bottom plate is determined in each carbonization chamber of the whole coke furnace.
The invention provides a scientific and accurate operation method for adjusting the stroke of the coal dragging bottom plate, and the method is simple to operate, time-saving and labor-saving and has high reliability.
