[0002] Since the invention of coking production technology more than 140 years ago, the horizontal row temperature measurement of coke ovens has always relied on manual measurement. The temperature at the upper part of the coke oven is high, the dust is large, and the working environment is harsh. Replacing manual temperature measurement with automatic temperature measurement is the consistent requirement of the coking industry and the basic condition for realizing automation and unmanned operation in coke oven coking.
[0003] A horizontal row temperature measurement mechanism for coke ovens is the basic mechanism for realizing the automation of horizontal row temperature measurement of coke ovens. A horizontal row temperature measurement mechanism for coke ovens cooperates with electrical appliances and an automatic control part to realize automatic temperature measurement of the horizontal row of coke ovens.
[0004] A horizontal row temperature measurement mechanism for coke ovens has the following advantages: it can adapt to the horizontal row direction to perform automatic temperature measurement through various obstacles. On the path of the horizontal row temperature measurement direction, there are tracks of the oven top car, water seal seats, water supply pipes of the water seal seats, and obstacles formed by gas riser pipes. The switch cover component and temperature measurement component for automatic temperature measurement can perform automatic measurement of the horizontal row temperature without being affected by these obstacles; the accuracy error of the thermometer is better than five thousandths; due to the large number of horizontal row vertical flues, it takes several days for manual horizontal row temperature measurement to measure the temperature of all horizontal row vertical flues once. A horizontal row temperature measurement mechanism for coke ovens can measure the temperature of all horizontal row vertical flues in about one day. Summary of the Invention
[0005] The purpose of the present invention is to realize automatic measurement of the horizontal row temperature of coke ovens, replace manual temperature measurement in the harsh working environment on the oven top, and is the basic mechanism for realizing the automation and unmanned operation of coke oven temperature measurement.
[0006] The present invention provides the following technical solution: A horizontal row temperature measurement mechanism for coke ovens includes a horizontal row viewing hole opening cover component, a horizontal row viewing hole temperature measurement component, and a horizontal row viewing hole closing cover component; the horizontal row viewing hole opening cover component, the horizontal row viewing hole temperature measurement component, and the horizontal row viewing hole closing cover component have the same interval distance from three consecutive horizontal row viewing holes of the coke oven and are installed above the viewing holes; there is an electromagnetic suction switch cover head below the horizontal row viewing hole opening cover component and the horizontal row viewing hole closing cover component, and the electromagnetic suction switch cover head can lift and lower the viewing hole cover with electromagnetic force; the horizontal row viewing hole temperature measurement component installs a thermometer, and the thermometer moves along the horizontal row viewing hole direction to measure the temperature; the horizontal row viewing hole opening cover component, the horizontal row viewing hole temperature measurement component, and the horizontal row viewing hole closing cover component move along the straight line direction of the coke oven viewing holes to measure the temperature of each horizontal row viewing hole of the coke oven.
[0007] Further, for the horizontal flue inspection hole cover opening component, there is a support at the upper end; and an electromagnetic force switch cover head at the lower end. The electromagnetic force switch cover head uses electromagnetic force to lift and lower the inspection hole cover. The horizontal flue inspection hole cover opening component is used to move the inspection hole cover to one side of the inspection hole for opening the cover.
[0008] Further, for the horizontal flue inspection hole temperature measuring component, there is a support at the upper end; and a thermometer is installed on the support. The thermometer moves to measure the temperature of the horizontal flue inspection hole.
[0009] Further, for the horizontal flue inspection hole cover closing component, there is a support at the upper end; and an electromagnetic force switch cover head at the lower end. The electromagnetic force switch cover head uses electromagnetic force to lift and lower the inspection hole cover.

[0010] Further, including the horizontal flue inspection hole cover opening component, the horizontal flue inspection hole temperature measuring component, and the horizontal flue inspection hole cover closing component at one end close to the riser pipe. During temperature measurement, the end of the support corresponds to the inspection hole at the end between two riser pipes. When the horizontal flue inspection hole cover opening component, the horizontal flue inspection hole temperature measuring component, and the horizontal flue inspection hole cover closing component need to move to the next horizontal flue inspection hole, the supports of the horizontal flue inspection hole cover opening component, the horizontal flue inspection hole temperature measuring component, and the horizontal flue inspection hole cover closing component are shortened to prevent the riser pipe from blocking the movement. When moving above the next horizontal flue inspection hole, the supports of the horizontal flue inspection hole cover opening component, the horizontal flue inspection hole temperature measuring component, and the horizontal flue inspection hole cover closing component extend to be able to open the inspection hole cover at the end of the horizontal row close to the riser pipe, measure the temperature of the vertical flue at the end of the horizontal row close to the riser pipe, and close the inspection hole cover at the end of the horizontal row close to the riser pipe.
[0011] Further, for the electromagnetic force switch cover head at the lower part of the horizontal flue inspection hole cover opening component, when opening the cover, it descends to contact the inspection hole cover to generate electromagnetic suction force. The electromagnetic suction force holds the inspection hole cover and connects it as a whole with the switch cover head. It rises to drive the inspection hole cover away from the inspection hole opening, drives the inspection hole cover to move to the unobstructed side, descends and places it on the top of the coke oven. The electromagnetic force disappears, and the electromagnetic force switch cover head rises away from the inspection hole cover to complete opening the cover.
[0012] Further, for the thermometer of the horizontal flue inspection hole temperature measuring component, it aligns with the opened inspection hole opening to measure the temperature of the temperature measuring point at the bottom of the vertical flue. The thermometer moves in the horizontal direction to measure the temperatures of all the temperature measuring points of the vertical flues in one horizontal row.
[0013] Further, for the electromagnetic force switch cover head at the lower part of the horizontal flue inspection hole cover closing component, when closing the cover, it descends to contact the inspection hole cover to generate electromagnetic suction force.

It rises to drive the inspection hole cover away from the top surface of the furnace, drives the inspection hole cover to move above the inspection hole opening, descends and places it on the inspection hole opening. The electromagnetic force disappears, and the electromagnetic force switch cover head rises away from the inspection hole cover to complete closing the cover.
[0014] The advantages of the present invention are as follows: The present invention is a transverse temperature measuring mechanism for coke ovens. Traditionally, the transverse temperature measurement of coke ovens has been carried out manually.

It adopts a transverse flue hole opening cover component, a transverse flue hole temperature measuring component, and a transverse flue hole closing cover component to perform opening the cover, temperature measurement, and closing the cover. The present invention solves the problem that there are multiple obstacles in the transverse temperature measurement direction affecting temperature measurement, and realizes automatic temperature measurement instead of manual operation. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The present invention does not add drawings. EMBODIMENTS
[0016] In order to more clearly illustrate the embodiments of the present invention, the following will briefly introduce the embodiments. Obviously, the following descriptions are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other embodiments can also be obtained according to these embodiments and are within the protection scope of the present invention.
[0017] This embodiment provides a transverse temperature measuring mechanism for a coke oven, including a transverse flue hole opening cover component, a transverse flue hole temperature measuring component, and a transverse flue hole closing cover component.
[0018] The transverse flue hole opening cover component is at the forefront in the straight-line moving direction. After the transverse flue hole opening cover component aligns with the flue hole cover below, the electromagnetic force switch cover head descends to contact the flue hole cover, generating an electromagnetic force to suck the flue hole cover. The transverse flue hole opening cover component drives the flue hole cover to rise away from the flue hole opening. The transverse flue hole opening cover component pushes the switch cover head. When there is an obstacle on the right, the electromagnetic force switch cover head moves left, and when there is an obstacle on the right, the electromagnetic force switch cover head moves left to make the switch cover head leave the flue hole opening. The transverse flue hole opening cover component drives the electromagnetic force switch cover head to move down to the furnace top surface, the electromagnetic force disappears, the electromagnetic force switch cover head releases the flue hole cover, and the electromagnetic force switch cover head moves up to leave the flue hole cover, realizing the function of opening the cover.
[0019] The transverse flue hole temperature measuring component is at the middle position in the straight-line moving direction. It moves along the straight-line direction to the position above the opened transverse flue holes and aligns with the flue hole positions. The temperature measuring instrument on the transverse flue hole temperature measuring component moves along the transverse direction to measure the temperature of the temperature measuring points at the bottom of each flue hole, completing the temperature measurement of the vertical flues of an entire row of transverse flue holes.
[0020] At the rearmost position of the horizontal row of fire hole closing cover components moving straight in the direction of the fire hole, the horizontal row of fire hole closing cover components drive the electromagnetic force switch cover head to move above the fire hole cover. The horizontal row of fire hole closing cover components control the electromagnetic force switch cover head to move downward to contact the fire hole cover, generating electromagnetic suction force to make the fire hole cover and the switch cover head suck together as one. The horizontal row of fire hole closing cover components control the switch cover head to drive the fire hole cover to move upward and move in the direction of the fire hole opening. When reaching above the fire hole opening, the electromagnetic force switch cover head drives the fire hole cover to move downward to the fire hole opening, making the fire hole cover cover on the fire hole opening. The electromagnetic force switch cover head eliminates the electromagnetic suction force and releases the fire hole cover, and the electromagnetic force switch cover head moves upward to leave the fire hole cover, and the cover closing is completed.
[0021] After the temperature measurement of a horizontal row is completed, the horizontal row of fire hole opening cover components, the horizontal row of fire hole temperature measurement components, and the horizontal row of fire hole closing cover components shorten at the riser pipe end to avoid the obstruction of the riser pipe, and then move along the straight direction of the fire hole to the next horizontal row for temperature measurement. The temperature measurement process repeats the processes in

[19] until all the horizontal row temperature measurements are completed.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
