On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] The present invention provides a measuring device for a rotary annealing furnace, the measuring device is used to measure the assembly accuracy of the annealing furnace, such as Figure 1 As shown, the measuring device includes: a first bracket 1, a reinforcement 2, a fixing plate 3, a rotatable clamping plate 4, a support plate 5, a second bracket 6 and a base 7; wherein,

[0045] One end of the first bracket 1 is placed on the ground, and the first bracket 1 is located at the center of the annealing furnace;

[0046] The reinforcement member is installed on the inner side of the first bracket 1;

[0047] The fixing plate 3 is located on the reinforcement member 2;

[0048] A rotatable clamping plate 4 is located on the fixed plate 3, and the rotatable clamping plate is used to fix a ruler, and the ruler is used to measure the assembly radius of each trolley frame of the annealing furnace;

[0049] A support plate 5 is located at the other end of the first bracket 1;

[0050] A second bracket 6, located on the support plate 5;

[0051] The base 7 is located on the second bracket 6, and an angle measuring mechanism is installed on the base 7, and the angle measuring mechanism is used to measure the assembly roundness of each trolley frame. The angle measuring mechanism can be a theodolite.

[0052] Specifically, refer to Figure 1 The first bracket 1 includes four columns, and a reinforcement member 2 is installed in the inner space of the first bracket 1. The reinforcement member 2 is respectively connected to the middle parts of three of the columns, so that the reinforcement member 2 is suspended in the inner space of the first bracket 1.

[0053] A fixing plate 3 is arranged on the reinforcement member 2, and a column 8 is arranged on the fixing plate 3; one end of the rotatable clamping plate 4 is annular, and one end of the rotatable clamping plate 4 is sleeved on the column 8. In this way, the rotatable clamping plate 4 can rotate 360 ​​degrees along the column 8.

[0054] The other end of the rotatable clamping plate 4 is rectangular, and one end of the ruler can be placed on the other end of the rotatable clamping plate 4, and the zero scale position of the ruler, the center of the angle measuring mechanism and the center position of the annealing furnace coincide.

[0055] In order to prevent the ruler from moving during the measurement process, the device also includes: a plurality of pressing plates 9; when the ruler is placed on the other end of the rotatable clamping plate 4, the pressing plate 9 is fixed above the ruler.

[0056] Continue to refer Figure 1 , the device further comprises: a fixing component 10;

[0057] A plurality of first screw holes are provided on the other end of the rotatable clamping plate 4, and second screw holes are provided at both ends of the pressing plate 9; the fixing component 10 fixes the pressing plate 9 to one end of the rotatable clamping plate 4 through the first screw holes and the second screw holes to prevent the scale from moving.

[0059] In order to ensure the horizontal state of the ruler, a tensioning component with a preset weight is connected to the other end of the ruler; wherein the preset weight may be 15 kg, and the tensioning component may be a hammer, a stone, etc.

[0060] After assembling the lower trolley, the roundness of each trolley frame needs to be measured, so the measuring equipment also needs to be arranged to place the angle measurement mechanism. Figure 1 A support plate 5 is also installed at the other end of the first bracket 1, a second bracket 6 is also installed above the support plate 5, and a base 7 is installed above the second bracket 6. The base 7 is annular in the middle, and the angle measuring mechanism can be stuck in the base 7.

[0061] Furthermore, in order to facilitate observation of whether the zero scale position of the ruler, the center of the angle measuring mechanism and the center position of the annealing furnace coincide with each other, a hole is opened in the middle of the support plate 5 .

[0062] Based on the above measuring equipment, the radius and roundness of the assembled trolley frame can be measured. It should be noted that when assembling the lower trolley, since the lower trolley includes multiple trolley frames, after each trolley frame is assembled, the roundness and radius of the trolley frame need to be measured.

[0063] Moreover, since there are a large number of trolley frames, they are assembled in groups. The tail trolley frame of the current group serves as the reference fan trolley frame of the next group of trolley frames, so that each group of trolley frames is connected, thereby better improving the assembly accuracy.

[0064] For example, if the trolley frame includes 25 panels, the first group of trolley frames may include the 1st to 6th trolley frames, the second group of trolley frames may include the 6th to 11th trolley frames, the third group of trolley frames may include the 11th to 16th trolley frames, the fourth group of trolley frames may include the 16th to 21st trolley frames, and the fifth group of trolley frames may include the 21st to 25th trolley frames.

[0065] The structure of each trolley frame is the same. Each trolley frame includes: a first detection track, a guide track and a second detection track from the outside to the center of the annealing furnace; a hydraulic cylinder push seat is installed on the first detection track; wherein,

[0066] Keep one end of the ruler at the same height as the other end of the ruler;

[0067] The ruler is used to measure a first distance between the second detection track and the center position of the annealing furnace, a second distance between the guide track and the center position of the annealing furnace, and a third distance between the hydraulic cylinder push seat and the center position of the annealing furnace;

[0068] The angle measuring mechanism is used to measure the assembly roundness of each trolley frame.

[0069] Among them, multiple support wheels are arranged under the first detection track and the second detection track, and a guide mechanism is placed between the support wheels under the second detection track. The guide wheels of the guide mechanism are attached to the guide track to prevent the guide track from shifting during the rotation of the annealing furnace.

[0070] In one embodiment, a first hydraulic cylinder push seat and a second hydraulic cylinder push seat are installed on the first detection track of each trolley frame; when the angle measuring mechanism is used to measure the assembly roundness of each trolley frame in the current group of trolley frames, the following is implemented:

[0071] When the cursor of the angle measuring mechanism is launched onto the reference fan trolley frame in the current group of trolley frames, the angle measuring mechanism is reset to zero;

[0072] For the current fan trolley frame in the current group of trolley frames, the angle measuring mechanism is controlled to rotate to the first hydraulic cylinder push seat of the current fan trolley frame, the center of the current fan trolley frame and the second hydraulic cylinder push seat of the current fan trolley frame in sequence, and the corresponding first angle, second angle and third angle are obtained respectively;

[0073] If it is determined that the first angle corresponding to each sash frame in the current group of trolley frames meets the first angle threshold, the second angle meets the second angle threshold, and the third angle meets the third angle threshold, then it is determined that the assembly roundness of the current sash trolley frame meets the requirements.

[0074] For details, please refer to Figure 2 , Figure 2It is a schematic diagram of assembling the first group of trolley frames. In the first group of trolley frames, the reference fan trolley frame is the first fan trolley frame (NO.1). After the second fan (NO.2) trolley frame is assembled with the first fan trolley frame, the cursor of the angle measuring mechanism is moved to the preset mark on the first hydraulic cylinder push seat of the second fan trolley frame. At this time, the corresponding first angle can be read from the angle measuring mechanism; the cursor of the angle measuring mechanism is continued to be moved to the preset mark on the central axis of the second fan trolley frame. At this time, the corresponding second angle can be read from the angle measuring mechanism; the cursor of the angle measuring mechanism is continued to be moved to the preset mark on the second hydraulic cylinder push seat of the second fan trolley frame. At this time, the corresponding third angle can be read from the angle measuring mechanism.

[0075] from Figure 2 It can be seen that the standard value of the first angle should be 12°42′, and the value range of the first angle threshold can fluctuate 0.5° above and below the first angle standard value. If the first angle is within the value range of the first angle threshold, it means that the first angle meets the first angle threshold. Similarly, the second angle and the third angle are also determined to meet the requirements using the same method. If it is determined that the first angle meets the first angle threshold, the second angle meets the second angle threshold, and the third angle meets the third angle threshold, it is determined that the assembly roundness of the second trolley frame meets the requirements.

[0076] Then, use a ruler to measure the first distance between the first detection rail in the second trolley frame and the center position of the annealing furnace, the second distance between the guide rail and the center position of the annealing furnace, and the third distance between the hydraulic cylinder push seat and the center position of the annealing furnace; if it is determined that the first distance meets the first distance threshold, the second distance meets the second distance threshold, and the third distance meets the third distance threshold, then it is determined that the assembly radius of the second trolley frame meets the requirements.

[0077] The assembly roundness and assembly radius of the remaining trolley frames in the current group of trolley frames are measured in the same way as the second trolley frame, so it is not repeated here. The only difference is that the first angle threshold, the second angle threshold, the third angle threshold, the first distance threshold, the second distance threshold and the third distance threshold corresponding to each trolley frame are different.

[0078] After the first set of trolley frames are assembled, Figure 3 shown.

[0079] It can be seen that the measuring device of the present embodiment is placed at the center of the annealing furnace to ensure that the center of the measuring device coincides with the center of the annealing furnace. Then, after assembling the trolley frames of each fan, the ruler can be used to measure the assembly radius on each trolley frame, and since the ruler is fixed on the rotatable clamping plate, it can be rotated to a suitable position to conveniently measure the trolley frames at different positions. Similarly, an angle measuring mechanism is installed on the base, so it is also convenient to measure the assembly roundness of each trolley frame, without the need to manually repeatedly adjust the position of the ruler and the angle measuring mechanism, thereby improving the measurement efficiency of the assembly accuracy of the annealing furnace.

[0080] Based on the same inventive concept as the above-mentioned embodiment, the present invention also provides a measuring method for a rotary annealing furnace, which is applied to the above-mentioned measuring device, such as Figure 4 As shown, the method comprises the following steps:

[0081] S410, using an angle measuring mechanism to measure the assembly roundness of each trolley frame in the current group of trolley frames.

[0082] As mentioned above, due to the large number of trolley frames, they are assembled in groups. The tail trolley frame of the current group serves as the reference fan trolley frame of the next group of trolley frames, so that each group of trolley frames is connected, thereby better improving the assembly accuracy.

[0083] For example, if the trolley frame includes 25 panels, the first group of trolley frames may include the 1st to 6th trolley frames, the second group of trolley frames may include the 6th to 11th trolley frames, the third group of trolley frames may include the 11th to 16th trolley frames, the fourth group of trolley frames may include the 16th to 21st trolley frames, and the fifth group of trolley frames may include the 21st to 25th trolley frames.

[0084] The structure of each trolley frame is the same. Each trolley frame includes: a first detection track, a guide track and a second detection track from the outside to the center of the annealing furnace; a hydraulic cylinder push seat is installed on the first detection track; wherein,

[0085] Keep one end of the ruler at the same height as the other end of the ruler;

[0086] The ruler is used to measure a first distance between the second detection track and the center position of the annealing furnace, a second distance between the guide track and the center position of the annealing furnace, and a third distance between the hydraulic cylinder push seat and the center position of the annealing furnace;

[0087] The angle measuring mechanism is used to measure the assembly roundness of each trolley frame.

[0088] Among them, multiple support wheels are arranged under the first detection track and the second detection track, and a guide mechanism is placed between the support wheels under the second detection track. The guide wheels of the guide mechanism are attached to the guide track to prevent the guide track from shifting during the rotation of the annealing furnace.

[0089] In one embodiment, a first hydraulic cylinder push seat and a second hydraulic cylinder push seat are installed on the first detection track of each trolley frame; and the assembly roundness of each trolley frame in the current group of trolley frames is measured by using an angle measuring mechanism, including:

[0090] When the cursor of the angle measuring mechanism is emitted to the reference fan trolley frame in the current group of trolley frames, the angle measuring mechanism is set to zero;

[0091] For the current fan trolley frame in the current group of trolley frames, the angle measuring mechanism is controlled to rotate to the first hydraulic cylinder push seat of the current fan trolley frame, the center of the current fan trolley frame and the second hydraulic cylinder push seat of the current fan trolley frame in sequence, and the corresponding first angle, second angle and third angle are obtained respectively;

[0092] If it is determined that the first angle corresponding to each sash frame in the current group of trolley frames meets the first angle threshold, the second angle meets the second angle threshold, and the third angle meets the third angle threshold, it is determined that the assembly roundness of the current sash trolley frame meets the requirements.

[0093] For details, please refer to Figure 2 , Figure 2 It is a schematic diagram of assembling the first group of trolley frames. In the first group of trolley frames, the reference fan trolley frame is the first fan trolley frame (NO.1). After the second fan (NO.2) trolley frame is assembled with the first fan trolley frame, the cursor of the angle measuring mechanism is moved to the preset mark on the first hydraulic cylinder push seat of the second fan trolley frame. At this time, the corresponding first angle can be read from the angle measuring mechanism; the cursor of the angle measuring mechanism is continued to be moved to the preset mark on the central axis of the second fan trolley frame. At this time, the corresponding second angle can be read from the angle measuring mechanism; the cursor of the angle measuring mechanism is continued to be moved to the preset mark on the second hydraulic cylinder push seat of the second fan trolley frame. At this time, the corresponding third angle can be read from the angle measuring mechanism.

[0094] from Figure 2It can be seen that the standard value of the first angle should be 12°42′, and the value range of the first angle threshold can fluctuate 0.5° above and below the first angle standard value. If the first angle is within the value range of the first angle threshold, it means that the first angle meets the first angle threshold. Similarly, the second angle and the third angle are also judged in the same way to see whether they meet the requirements. If it is determined that the first angle meets the first angle threshold, the second angle meets the second angle threshold, and the third angle meets the third angle threshold, it is determined that the assembly roundness of the second trolley frame meets the requirements.

[0095] The assembly roundness of the remaining sash trolley frames is measured in the same manner as the second sash trolley frame, so it will not be repeated here.

[0096] S411, using a ruler to measure the assembly radius of each trolley frame in the current group of trolley frames in turn; the assembly radius includes: a first distance between the first detection rail and the center position of the annealing furnace, a second distance between the guide rail and the center position of the annealing furnace, and a third distance between the hydraulic cylinder push seat and the center position of the annealing furnace.

[0097] Then connect one end of the ruler to the tensioning component of the preset weight, pull the other end of the ruler to the first detection track, and one end of the ruler is at the same height as the other end of the ruler. Use the ruler to measure the assembly radius of each trolley frame in the current group of trolley frames in turn; the assembly radius includes: the first distance between the second detection track and the center position of the annealing furnace, the second distance between the guide track and the center position of the annealing furnace, and the third distance between the hydraulic cylinder push seat and the center position of the annealing furnace.

[0098] refer to Figure 2 Taking the second trolley frame as an example, a ruler can be used to measure the first distance between the second detection track in the second trolley frame and the center position of the annealing furnace, the second distance between the guide track and the center position of the annealing furnace, and the third distance between the hydraulic cylinder push seat and the center position of the annealing furnace; if it is determined that the first distance meets the first distance threshold, the second distance meets the second distance threshold, and the third distance meets the third distance threshold, then it is determined that the assembly radius of the second trolley frame meets the requirements.

[0099] The assembly radius of the remaining trolley frames in the current set of trolley frames is measured in the same way as the second trolley frame, so it is not repeated here. The only difference is that the first distance threshold, the second distance threshold and the third distance threshold corresponding to each trolley frame are different.

[0100] S412: If it is determined that the first distance satisfies the first distance threshold, the second distance satisfies the second distance threshold, the third distance satisfies the third distance threshold, and the assembly roundness of each trolley frame in the current group of trolley frames satisfies the corresponding angle threshold, it is determined that the current group of trolley frames is assembled successfully.

[0101] If it is determined that the first distance satisfies the first distance threshold, the second distance satisfies the second distance threshold, the third distance satisfies the third distance threshold, and the assembly roundness of each trolley frame in the current group of trolley frames satisfies the corresponding angle threshold, then it is determined that the current group of trolley frames is assembled successfully.

[0102] In one embodiment, after determining that the current group of trolley frames is successfully assembled, the method further includes:

[0103] The tail trolley frame in the current group of trolley frames is used as the reference fan trolley frame of the next group of trolley frames;

[0104] Taking the reference fan trolley frame of the next set of trolley frames as the reference, measure the assembly roundness and assembly radius of the next set of trolley frames.

[0105] Taking the first set of trolley frames as an example, after confirming that the first set of trolley frames is assembled successfully, the tail trolley frame of the first set of trolley frames (since the first set of trolleys includes the 1st to 6th trolley frames, the tail trolley frame of the first set of trolley frames is the 6th trolley frame) is used as the reference trolley frame, and the next set of trolley frames is measured in the same way. And so on, until all trolley frames are measured.

[0106] It should be noted that if it is determined that the assembly of a certain trolley frame does not meet the requirements, it is necessary to fine-tune the installation position of the trolley frame of the sash, and then continue to measure until the assembly accuracy of the trolley frame of the sash meets the requirements.
