Description

Technical Field

[0001] This invention relates to the field of coking temperature measurement equipment technology, and in particular to a track-mounted coking oven temperature measurement system. Background Technology

[0002] Currently, the coking industry commonly uses handheld infrared thermometers to measure the temperature of all representative flues on the coke oven side every four hours. After measurement, the results are manually imported into a computer, where specialized software calculates the linear temperature. Finally, the gas flow is adjusted based on the linear temperature deviation to ensure the furnace temperature. However, manual measurement involves long intervals, harsh working environments, and the results are highly susceptible to human error. It requires multiple people working together, and the accuracy of the temperature measurements is difficult to guarantee.

[0003] Chinese patent application CN211896789U discloses an automatic temperature measuring device for the inspection hole on the top of a coke oven. The device uses a control unit to move a railcar to the top of the integrated inspection hole to be inspected. The bottom of the railcar is pressed against one side of an automatic flip-top device, and the flip-top is achieved by lever operation. The infrared temperature measuring device's detection head is aligned with the center of the integrated fire-viewing hole to detect the temperature. The infrared temperature measuring device then sends the measured temperature data to the control device, which in turn sends the data to the receiving terminal, thus achieving the temperature measurement effect of mobile inspection. Although this reduces the risk of manual temperature measurement, lowers labor costs, and improves coke quality, the automatic flip-top device is located on one side of the railcar. The lateral force generated when the cover is opened causes the railcar's stability to deteriorate. When the cover is pressed up by the railcar, it generates vertical vibration, affecting the stability and service life of the railcar. The upward reaction force of the flip-top device on the railcar reduces the friction between the railcar and the track, making it prone to slippage, especially in outdoor rainy or snowy weather. Increasing the weight of the railcar itself will increase the load on the traveling mechanism, increasing energy consumption during travel and raising operating costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a track-mounted coke oven temperature measuring robot, which addresses the above-mentioned technical deficiencies by using a cover-opening mechanism located at the bottom of the shell, and a temperature measuring unit fixed in the shell and located above the cover-opening mechanism, thereby solving the problem of the lateral force generated during cover opening causing poor stability of the track vehicle.

[0036] The temperature measuring unit 3 is provided with an air nozzle 4 on one side. The air nozzle 4 is connected to the air pump 42 through an air pipe 41. The air pump 42 is located inside the housing 1.

[0037] The lid-opening mechanism includes a lid-opening translation lever 2, which includes a guide portion 22 and a holding portion 23. The length direction of the holding portion 23 is parallel to the length direction of the track, and the holding portion 23 is located on one side of the temperature measuring unit 3.

A hinge limiting part 21 is connected to one side of the lid-opening sliding lever 2, and the hinge limiting part 21 is fixed to the bottom of the housing 1 near the temperature measuring unit 3. A compression and reset mechanism 24 is provided between the lid-opening sliding lever 2 and the hinge limiting part 21. When the compression and reset mechanism 24 is compressed, the lid-opening sliding lever 2 can rotate around the hinge shaft 20 at a certain angle. A limiting block is provided on the side of the lid-opening sliding lever 2 opposite to the hinge limiting part 21, or a pull rod is provided between the lid-opening sliding lever 2 and the hinge limiting part 21, so that the lid-opening sliding lever 2 can only rotate in one direction.

[0038] Combination Figures 7 to 8 As shown, in this embodiment, when the track-mounted coke oven temperature measuring robot moves above the translational temperature measuring hole cover, the height of the cover-opening translational guide column 60 coincides with the movement path of the cover-opening translational lever 2. Combined with... Figures 2 to 4 As shown, in this embodiment, two sets of lid-opening translation levers 2 are provided symmetrically. The temperature measuring unit 3 is set between the two sets of lid-opening translation levers 2. The fixing seats 63 of the adjacent two translational temperature measuring hole furnace covers are arranged opposite to each other. In use, the reciprocating movement of the temperature measuring robot is achieved by the two sets of lid-opening translation levers 2 symmetrically, which can open adjacent single or double covers 6.

[0039] The temperature measuring unit 3 is electrically connected to the control module. The walking mechanism includes four rollers 5, at least two of which are connected to a rotary drive mechanism. The rollers 5 are in rolling contact with the set track. A clamping rod 51 is provided on the lower side of the rollers 5. The clamping rod 51 is arranged parallel to the rotation axis of the rollers 5. One end of the clamping rod 51 is pressed into the housing 1 by a limiting spring 52. The other end of the clamping rod 51 is provided with a clamping wheel 53. The clamping wheel 53 and the rollers 5 are respectively arranged on the upper and lower sides of the track.

[0040] Example 2, combined with Figures 1 to 5 As shown, a sliding temperature measuring hole furnace cover includes a cover body 6, the top of which is provided with a pin 61, and the upper part of the cover body 6 is connected to a sliding guide mechanism and a reset part.

[0041] The translational guiding mechanism includes a swing arm 62 and a fixed base 63. One end of the swing arm 62 is connected to the pin 61, and the other end of the swing arm 62 is provided with a cam disk 620. The cam disk 620 is hinged to the end of the fixed base 63. A push block 631 and a return spring 632 are contacted on one side of the cam disk 620. Unlike embodiment one, a sliding sleeve 6201 is provided at the hinge position between the cam disk 620 and the fixed base 63. A movable columnar cam 6202 is sleeved on the outer side of the sliding sleeve 6201 and fixed to the bottom of the cam disk 620. The lower part of the movable columnar cam 6202 is provided with a protrusion. The bottom of the movable columnar cam 6202 slides in contact with the fixed columnar cam 6203. The top of the fixed columnar cam 6203 is provided with a fixed cam groove 6204 that is adapted to the protrusion. The bottom side of the fixed cam groove 6204 is provided with a notch 6205. The upper part of the fixed columnar cam 6203 is coaxially provided with an annular dirt-collecting groove 6206. The annular dirt-collecting groove 6206 communicates with the fixed cam groove 6204. The bottom of the fixed columnar cam 6203 is provided with a positioning block 6207, which is engaged in the fixed seat 63.

[0042] In use, the cover 6 is placed on top of the temperature measuring hole. The cam disc 620, in conjunction with the push block 631 and the return spring 632, allows the cover 6 to swing open to one side and then horizontally return to its original position. When the guide post 60 is pushed to one side, the cover 6 swings horizontally open with the swing arm 62. The moving columnar cam 6202 rotates with the swing arm 62, and its axial interaction with the fixed cam groove 6204 pushes the swing arm 62 and cover 6 upwards during horizontal swinging. This simultaneous horizontal opening and upward movement of the cover 6 prevents external wear that could affect its service life, avoids jamming during opening, and improves the sealing effect when the cover 6 is closed. The notch 6205 and the annular dirt-collecting groove 6206 prevent foreign objects from getting stuck in the fixed columnar cam 6203 and affecting its accurate engagement.

[0043] Example 3, combined with Figures 1 to 5 As shown, a sliding temperature measuring hole furnace cover includes a cover body 6, the top of which is provided with a pin 61, and the upper part of the cover body 6 is connected to a sliding guide mechanism and a reset part.

[0044] The translational guide mechanism includes a slide 66 and a fixed base 63. The fixed base 63 has guide grooves 634 on both sides that connect with the edge of the temperature measuring hole. The slide 66 is slidably disposed along the guide grooves 634 in the fixed base 63. The fixed base 63 has a reset part at the end away from the temperature measuring hole. The reset part includes a columnar spring 65. One end of the columnar spring 65 is abutted against the end of the fixed base 63, and the other end is abutted against one end of the slide 66.

[0045] When in use, when the track-type coke oven temperature measuring robot passes through the upper part of the corresponding cover 6, the cover opening translation lever 2 contacts the pin 61 and pushes the slide 66 horizontally to one side. The slide 66 drives the cover 6 to move horizontally along the guide groove 634 to open the cover 6. When the cover opening translation lever 2 disengages from the pin 61, the cover 6 is pushed by the column spring 65 to close the temperature measuring hole.

[0046] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
