The filter fan includes a fan body, and end plates and connecting pipes are welded on both sides of the fan body. The fan body has two fan surfaces.

[0003] Since it is the welding of stainless steel thin plates, the input line energy is high and the deformation is large. It is difficult to ensure that the centers of the two fan surfaces and the center of the connecting pipe are in a straight line after welding. Therefore, after welding is completed, it is necessary to detect the deformed position of the filter fan and perform plastic surgery. Since the bottom end of the connecting pipe and the fan surface of the fan body are not on the same plane, workers usually perform inspections on a platform. The filter fan is placed on the platform with the connecting pipe outside the platform. The workers observe whether there is a gap between the fan body and the upper surface of the platform, and then place the filter fan vertically on the platform to observe whether there is a gap between the end plate and the upper surface of the platform. The deformation position of the filter fan is detected and corresponding plastic surgery is performed using tools.

[0004] However, this method requires first detecting the deformation position of the fan body of the filter fan, and then two workers cooperate to erect the end plate, one to hold the end plate, and the other to check the deformation position of the end plate, and then detect the deformation position of the entire filter fan, which is time-consuming and labor-intensive, and has low work efficiency.

[0037] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a filter fan deformation detection device for detecting the deformation position of a welded filter fan, wherein the filter fan comprises a fan body, and end plates and pipes are respectively welded on both sides of the fan body, and the filter fan deformation detection device comprises a stepped platform 1, a limiting plate 2 and a limiting mechanism;

[0039] The step platform 1 has a first table top, a second table top and a third table top which are successively lowered, and the limit plate 2 is installed on the first table top;

[0040] The first table is used to place the fan body, and the second and third tables are used to place the connecting pipes;

[0041] The limiting mechanism is used to push the connecting pipe toward the limiting plate 2 so that the end plate contacts the limiting plate 2 .

[0042] The fan body of the filter fan is placed on the first table, and the connecting pipe of the filter fan is placed on the second table and the third table, so that the staff can visually check whether there is a gap between the fan body of the filter fan and the first table, and detect the deformation position of the fan body of the filter fan. Since the limiting mechanism pushes the connecting pipe of the filter fan toward the limiting plate 2, the end plate of the filter fan is in contact with the limiting plate 2, and then it is convenient to detect whether there is a gap between the end plate and the limiting plate 2, and detect the deformation position of the end plate of the filter fan, which saves time and effort, and does not require two staff members to cooperate in detecting the deformation position of the end plate of the filter fan, thereby improving work efficiency.

[0043] According to one embodiment of the utility model, Figure 2 As shown, the limiting mechanism includes a top rod 3 and a limiting seat 4;

[0044] The limit seat 4 is provided with a sliding hole 401, and the top rod 3 is slidably connected in the sliding hole 401;

[0045] The length direction of the sliding hole 401 and the length direction of the stepped platform 1 are the same as the length direction of the push rod 3;

[0046] The push rod 3 is used to abut against the connecting pipe.

[0047] After placing the fan body of the filter fan on the first table, manually push the push rod 3 to slide in the sliding hole 401, so that the push rod 3 abuts against the connecting pipe, and then the end plate contacts the limit plate 2, which is convenient for workers to detect the deformation position of the filter fan end plate.

[0048] According to an embodiment of the present invention, the limiting seat 4 is connected to the third table surface of the step platform 1 through a plurality of fasteners, and the fasteners are fixing bolts.

[0049] According to an embodiment of the present utility model, the top rod 3 includes a rod body 301 and a cone 302 connected to each other;

[0050] The cone 302 is connected to one end of the rod body 301 close to the limiting plate 2 .

[0051] The cone 302 can also be replaced by a conical frustum, and the diameter of the conical frustum at one end close to the rod body 301 is larger than the diameter at the other end.

[0052] The cone 302 is partially inserted into the connecting pipe of the filter fan. The maximum diameter of the cone 302 is larger than the inner diameter of the connecting pipe. After the cone 302 is inserted into a certain distance in the connecting pipe, the side wall of the cone 302 abuts against the inner wall of the connecting pipe, and the top rod 3 continues to move to push the filter fan to move so that its end plate abuts against the limit plate 2, which is convenient for detecting the deformation position of the end plate.

[0053] Of course, in this embodiment, the top rod 3 can also be in other forms, for example, the top rod 3 is a round rod, a square rod, etc. When a round rod is used, the diameter of the round rod is larger than the inner diameter of the connecting pipe, and the end of the connecting pipe is pressed against to push the filter fan. Its purpose does not deviate from the design concept of the utility model, and therefore, it should belong to the protection scope of the utility model.

[0054] According to an embodiment of the present utility model, the limiting mechanism further includes a driving assembly 5, and the driving assembly 5 includes a driving rod 501, a first rotating shaft 503, a second rotating shaft 504 and a connecting block 505;

[0055] The driving rod 501 is rotatably connected with a first rotating shaft 503, and the first rotating shaft 503 is rotatably connected with an end of the top rod 3 away from the limiting plate 2;

[0056] The connecting block 505 is connected to the side of the step platform 1 away from the limit plate 2, a bar hole 502 is opened on the driving rod 501, the second rotating shaft 504 is rotatably connected to the connecting block 505, and the second rotating shaft 504 is slidably connected to the bar hole 502. The second rotating shaft 504 can slide in the bar hole 502 and can also rotate relative to the bar hole 502.

[0057] The axis of the first rotating shaft 503 is parallel to the axis of the second rotating shaft 504 , and the axis direction of the first rotating shaft 503 is perpendicular to the length direction of the push rod 3 .

[0058] According to an embodiment of the present utility model, a first clearance groove 303 and a first through hole are formed in communication at one end of the push rod 3 away from the limiting plate 2;

[0059] The first rotating shaft 503 is rotatably connected to the first through hole.

[0060] The two sides of the driving rod 501 are in contact with two opposite side walls of the first clearance groove 303 respectively, which can limit the movement position of the driving rod 501 so that it will not move along the axial direction of the first rotating shaft 503, thereby better applying force.

[0061] like Figure 4 As shown, the first rotating shaft 503 includes a first cylinder 5031 and a second cylinder 5032 connected to each other, and also includes a threaded ring 5033. The diameter of the first cylinder 5031 is larger than the diameter of the first through hole. The second cylinder 5032 is provided with an external thread at one end away from the first cylinder 5031. The threaded ring 5033 is screwed on the external thread provided on the second cylinder 5032. The threaded ring 5033 and the first cylinder 5031 cooperate to limit the second cylinder 5032 from falling off from the first through hole. A circular hole adapted to the second cylinder 5032 is provided on the driving rod 501. A part of the second cylinder 5032 is rotatably connected in the circular hole, and another part of the second cylinder 5032 is rotatably connected in the first through hole. The driving rod 501 can be disassembled and separated from the top rod 3 by the provision of the first rotating shaft 503, so as to facilitate replacement.

[0062] According to an embodiment of the present utility model, the connecting block 505 is provided with a second paving groove 304 and a second through hole which are connected to each other;

[0063] The second rotating shaft 504 is rotatably connected in the second through hole, and one end of the driving rod 501 is located in the second easing groove 304 .

[0064] like Figure 4As shown, the second rotating shaft 504 includes a third cylinder, and limiting holes are provided at both ends of the third cylinder. Limiting pins are inserted into the limiting holes. The length of the limiting pins is greater than the diameter of the second through hole. The limiting pins are interference-connected in the second through hole, and can limit the third cylinder from being separated from the second through hole. The second rotating shaft 504, the connecting block 505 and the driving rod 501 are assembled by the limiting pins. Disassembly is more convenient and faster, the use effect is good, and the cost is low.

[0065] By providing the driving assembly 5, it is possible to save effort when pushing the push rod 3 to move.

[0066] For the convenience of description, one end of the strip hole 502 close to the first rotating shaft 503 is recorded as the first end, and the other end is recorded as the second end. In the initial position, the second rotating shaft 504 is located at the second end;

[0067] The staff holds the top end of the driving rod 501 and turns it counterclockwise, so that the driving rod 501 rotates around the first rotating shaft 503, giving a force to the top rod 3. Under the restriction of the sliding hole 401, the top rod 3 converts the rotational force of the driving rod 501 into a horizontal force, so that the top rod 3 slides along the length direction of the sliding hole 401. During the sliding process of the top rod 3, since the vertical distance from the first rotating shaft 503 to the second rotating shaft 504 does not change, the horizontal distance decreases. Therefore, the second rotating shaft 504 gradually approaches the first end of the strip hole 502. The provided strip hole 502 can avoid interfering with the movement of the driving rod 501 until the side wall of the cone 302 in the top rod 3 contacts the connecting pipe of the filter fan. Continue to apply force so that the end plate of the filter fan can abut against the limit plate 2, check the gap between the end plate and the limit plate 2, and thus detect the deformation position of the end plate.

[0068] Of course, in this embodiment, the driving component 5 can also be in other forms. For example, the driving component 5 is a cylinder, and the pushing direction of the cylinder is the same as the length direction of the sliding hole 401. The pushing end of the cylinder is connected to the push rod 3 and is electrically controlled. There is no need for manual pressure to be applied, which has a better labor-saving effect.

[0069] According to an embodiment of the utility model, the limiting plate 2 is a flat plate, and the flat plate is perpendicular to the step platform 1 .

[0070] According to an embodiment of the utility model, the limiting plate 2 is detachably connected to the step platform 1 via a connecting piece.

[0071] Preferably, the connecting member is a locking bolt, and both sides of the limit plate 2 are connected to a horizontal plate, each horizontal plate is provided with a first mounting hole, and the first table surface of the step platform 1 is symmetrically provided with a plurality of first screw holes, the width of the step platform 1 is greater than the width of the fan body, and the first screw holes are provided outside the fan body placement area, which does not affect the detection of the fan body, and each locking bolt is screwed into the first screw hole after passing through the first mounting hole. The position of the limit plate 2 can be adjusted by providing a plurality of first screw holes on the step platform 1, and fans of different lengths can be located on the first table surface for detection, which is highly practical.

[0072] Furthermore, the mandrel 3 is a combined rod, and the mandrel 3 also includes a screw rod, the large diameter end of the cone 302 is connected with the screw rod, the end of the rod body 301 close to the cone 302 is provided with a threaded hole, and the screw rod is screwed into the threaded hole, and the overall length of the mandrel 3 is adjusted by adjusting the length of the screw rod. The length direction of the screw rod is the same as the length direction of the rod body 301, and the screw rod and the rod body 301 are coaxially arranged.

[0073] Preferably, the entire stepped platform 1 is an integrated structure.

[0074] Optional, such as Figure 1 As shown, the step platform 1 includes an integrally formed first base body 101 and a second base body 102, and also includes a pad 103. The upper surface of the second base body 102 is lower than the upper surface of the first base body 101. The upper surface of the first base body 101 is the first table surface of the step platform 1. The second base body 102 is provided with a pad 103, and the pad 103 is detachably connected to the second base body 102 by a plurality of bolts. The pad 103 has a second table surface and a third table surface with successively decreasing heights.

[0075] In this embodiment, filter fans of different specifications can be tested by adjusting the position of the limiting plate 2 on the first table surface, the length of the screw exposed through the threaded hole, and replacing pads 103 of different specifications, which is more practical.

[0076] According to an embodiment of the utility model, there is a first transition surface between the first table top and the second table top, and there is a second transition surface between the second table top and the third table top;

[0077] The distance from the second transition surface to the limiting plate 2 is smaller than the distance from the push rod 3 to the limiting plate 2 .

[0078] When the distance from the second transition surface to the limit plate 2 is smaller than the distance from the top rod 3 to the limit plate 2, the filter fan as a whole is located between the top rod 3 and the limit plate 2, and the distance from the first transition surface to the limit plate 2 is adapted to the length of the fan body, so that the pipe of the filter fan can be placed on the second table and the third table. It should be noted that the pipe includes a connected transition section and a pipe section, the transition section is located on the second table, and the pipe section is located on the third table. Since the cross-sectional area of ​​the filter section of the pipe is large at one end away from the end plate and small at the other end, the second table is often an inclined table, which has a better support effect on the transition section of the pipe.

[0079] Specifically, the fan body has two relative first and second fan surfaces. First, the first fan surface and the end plate are inspected, and the filter fan is placed on the stepped platform 1, with the first fan surface in contact with the first table surface. By rotating the driving rod 501 counterclockwise, the driving rod 501 cooperates with the limiting seat 4, so that the rotational force of the driving rod 501 is converted into a force for horizontal movement of the top rod 3, and then the top rod 3 moves along the length direction of the sliding hole 401 to support the connecting pipe of the filter fan, and the driving rod 501 is continuously rotated until the end plate of the filter fan is in contact with the limiting plate 2 and then stops, and the gap between the first fan surface and the first table surface and the gap between the end plate and the limiting plate 2 are checked, and then the deformation position of the first fan surface and the deformation position of the end plate are detected at the same time. The deformation position of the second fan surface is detected by the above method, and then the deformation position of the filter fan can be detected, which saves time and effort. The overall structure of the filter fan deformation detection device is simple, the manufacturing cost is low, the positioning is accurate, and the work efficiency is improved.
