Description

Technical Field

[0001] The utility model relates to the technical field of cylinder size measurement, in particular to an outer diameter size measurement device for a large-diameter rotary reaction furnace cylinder body. Background Art

[0002] The Chinese patent with the authorization announcement number CN221376263U discloses a rotary reaction furnace roller support device, the structure of which includes an annular bracket for supporting the roller body. The annular bracket is an annular member coaxially connected to the outside of the reaction furnace cylinder body through a support rod, and is used for heat insulation between the reaction furnace cylinder body and the roller body. In order to make the roller body and the annular bracket more conveniently and stably installed, a plurality of stoppers are arranged on the outer side of the annular bracket in a circumferential array to avoid the risk of axial displacement after the roller body and the annular bracket are installed and connected.

[0003] From the structure of the above patent, due to the special position where the annular bracket is connected to the reaction furnace cylinder body, it is difficult to measure the outer diameter of the annular bracket by conventional measurement means. For example, when measuring with a traditional tape measure, only the outer circumference of the annular bracket can be measured to calculate its outer diameter. On the one hand, the accuracy of the tape measure is limited, there are certain errors in the direction of the tension of the tape measure itself, and the limitation of the stopper structure outside the annular bracket results in low measurement accuracy and large errors of this method. Since the diameter of the rotary furnace itself is very large, and the annular bracket is connected to the middle section of the rotary furnace cylinder body, it is difficult to accurately measure by conventional vernier calipers or other conventional measurement means. Therefore, how to accurately measure the outer diameter of the annular bracket for the special structure of the reaction furnace cylinder body with an annular bracket and stoppers connected to the outside has become a technical problem to be urgently solved.

[0040] The measuring device includes a first positioning mechanism 3 and a second positioning mechanism 4 with the same structure; it also includes a laser distance measuring sensor 5, and the laser distance measuring sensor 5 includes a transmitting device 51 and a receiving device 52;

[0041] The structures of the first positioning mechanism 3 and the second positioning mechanism 4 are the same; the first positioning mechanism 3 includes a first bracket 31, a second bracket 32, a first moving mechanism 33, a magnet block body 34, a second moving mechanism 35, a first roller 36, a second roller 37, a third roller 38, a fourth roller 39, and a telescopic rod 310;

[0042] The first bracket 31 and the second bracket 32 are connected by the first moving mechanism 33, and the first moving mechanism 33 is used to drive the second bracket 32 to move relative to the first bracket 31 along the X direction;

[0043] The magnet block body 34 is connected to the first bracket 31 through the second moving mechanism 35, and the second moving mechanism 35 is used to drive the magnet block body 34 to move along the Y direction;

[0044] The first roller 36 and the second roller 37 are rotatably and symmetrically connected to the first bracket 31. The axes of the first roller 36 and the second roller 37 are located in the same plane, and the plane is perpendicular to the X direction;

[0045] The third roller 38 and the fourth roller 39 are rotatably and symmetrically connected to the second bracket 32. The axes of the third roller 38 and the fourth roller 39 are located in the same plane, and the plane is perpendicular to the X direction;

[0046] One end of the telescopic rod 310 is connected to the first bracket 31, and the telescopic rod 310 is parallel to the X direction;

[0047] The transmitting device 51 of the laser distance measuring sensor 5 is connected to the telescopic rod 310 of the first positioning mechanism 3. The transmitting direction of the transmitting device 51 is perpendicular to the X direction, and the transmitting direction of the transmitting device 51 is located in the axial symmetry plane of the first roller 36 and the second roller 37;

[0048] The receiving device 52 of the laser distance measuring sensor 5 is connected to the telescopic rod 310 of the second positioning mechanism 4;

[0049] The measuring method of the large-diameter rotary reaction furnace cylinder outer diameter measuring device includes the following steps:

[0050] Step 1: Place the first positioning mechanism 3 and the second positioning mechanism 4 at the diagonal positions of the annular bracket body 2 respectively;

[0051] Step 2: Adjust the first moving mechanism 33 according to the axial width of the annular bracket body 2, so that the distance between the first roller 36 and the third roller 38 is equal to the axial width of the annular bracket body 2, and the distance between the second roller 37 and the fourth roller 39 is equal to the axial width of the annular bracket body 2, so that the first roller 36, the second roller 37, the third roller 38, and the fourth roller 39 are respectively pressed against the edge of the annular bracket body 2;

[0052] Step 3: Adjust the length of the telescopic rod 310 of the first positioning mechanism 3 and the length of the telescopic rod 310 of the second positioning mechanism 4, so that the receiving device 52 and the transmitting device 51 extend to the outside of one end of the rotary reaction furnace cylinder body 1, and make the projection directions of the receiving device 52 and the transmitting device 51 lie in the same plane, and the plane is perpendicular to the X direction;

[0053] Step 4: Slowly move the first positioning mechanism 3 or the second positioning mechanism 4 along the circumferential direction of the annular support body 2. When the distance measured by the laser distance sensor 5 is the longest, it means that the first positioning mechanism 3 and the second positioning mechanism 4 are exactly located at the diagonal corners of the annular support body 2. At this time, adjust the second moving mechanism 35 to make the magnet body 34 approach and adsorb on the outer circumferential part of the annular support body 2, and measure the outer diameter of the annular support body 2 through the laser distance sensor 5;

[0054] Step 5: Reverse-adjust the second moving mechanism 35 to make the magnet body 34 detach from the adsorption of the annular support body 2; reverse-adjust the first moving mechanism 33 to make the first roller 36, the second roller 37, the third roller 38 and the fourth roller 39 detach from the annular support body 2.

[0055] In the above embodiments, it should be noted that after the positioning is completed, the distance between the transmitting device 51 and the receiving device 52 of the laser distance sensor 5 can be exactly equal to the outer diameter of the annular support body 2, or there can be a fixed difference. The measured value of the laser distance sensor 5 is the distance between the transmitting device 51 and the receiving device 52, and the actual outer diameter measurement value is obtained by converting the fixed difference between the distance between the transmitting device 51 and the receiving device 52 and the outer diameter of the annular support body.

[0056] In the above embodiments, according to the structural characteristics of the large-diameter rotary reaction furnace cylinder body 1 and the annular support body 2, the structures of the specific first positioning mechanism 3 and the second positioning mechanism 4 are designed. The position of the four rollers is adjusted by the first moving mechanism 33 to make the four rollers press against the end face edge of the annular support body 2 for positioning. The receiving device 52 and the transmitting device 51 of the laser distance sensor 5 are positioned and connected through the telescopic rod 310. By finely adjusting the position of the first positioning mechanism 3 or the second positioning mechanism 4, the position of the first positioning mechanism 3 or the second positioning mechanism 4 is positioned by using the change of the numerical value measured by the laser distance sensor 5, so that the receiving device 52 and the transmitting device 51 are exactly located at the diagonal positions. The position of the magnet body 34 is adjusted by the second moving mechanism 35, and the first positioning mechanism 3 and the second positioning mechanism 4 are stably positioned by using magnetic adsorption, ensuring the stability and accuracy of the measured value. Since the position of the magnet body 34 is adjustable, it is applicable to magnetic adsorption positioning at the position of the block 21 of the annular support body 2 or non-block 21 positions. Compared with the method of measuring with a tape measure in the prior art, this solution has higher measurement accuracy.
