[0001] The present application relates to the field of power tower processing, and in particular to a cutting device for power tower steel structure profiles. Background Art

[0002] With the rapid development of the power industry, the demand for power towers is increasing, which makes the processing efficiency of power tower steel structure profiles one of the key factors to improve overall productivity. However, in the traditional profile processing process, especially in the two key steps of cutting and chamfering, due to the heavy reliance on manual operation, not only is the work efficiency low, but also it is easy to produce large processing errors, which seriously affects the product quality and subsequent assembly operations.

[0003] At present, when cutting and chamfering profiles on the market, it is necessary to first cut the profiles through a cutting machine to cut a whole long profile into multiple shorter profiles of a set length. Then the ends of the cut profiles are cut and chamfered for subsequent installation. At present, when cutting and chamfering, the staff needs to manually place the profile under the cutter and manually adjust the position of the profile to perform chamfering. Although this method is low in cost, due to the large differences in the experience and technical level of the operators, the chamfering accuracy is difficult to guarantee and the labor intensity is high.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a cutting device for a steel structure profile of an electric power tower. Figure 1The cutting device for the steel structure profile of the power tower includes a cutting platform 1, a first cutting tool 2 installed on the cutting platform 1, a first driving assembly 3 for driving the first cutting tool 2 to move, a second cutting tool 4 installed on the cutting platform 1, and a second driving assembly 5 for driving the second cutting tool 4 to move. Among them, a first rotating plate 11 and a second rotating plate 12 are rotatably connected on the cutting platform 1, the first cutting tool 2 and the first driving assembly 3 are installed on the first rotating plate 11, and the second cutting tool 4 and the second driving assembly 5 are installed on the second rotating plate 12. When the profile reaches the cutting platform 1 from one side of the cutting platform 1, the profile continues to move on the cutting platform 1. When the profile moves the first set length, the first rotating plate 11 also drives the first cutting tool 2 to rotate the set tool, so that the first cutting tool 2 is placed at a set angle with the profile, and the end of the profile can be chamfered by the first cutting tool 2; then the profile continues to move, and when it moves to the second set length, the second rotating plate 12 drives the first cutting tool 2 to reset, so that the first driving component 3 drives the first cutting tool 2 to cut the profile, thereby cutting the profile; then the profile continues to move the third set length, at this time the second driving component 5 drives the second cutting tool 4 to rotate, so as to cut and chamfer the other end of the profile by the second cutting tool 4, and the automatic cutting and chamfering operations of the profile can be realized through the same equipment, without the need for manual work by the staff, which greatly reduces the labor intensity of the staff when cutting and chamfering, has a high degree of automation, and greatly improves the chamfering accuracy.

[0033] Among them, the first cutting tool 2 and the second cutting tool 4 have the same structure, and the first drive component 3 and the second drive component 5 have the same structure. The only difference is the installation position. This application takes the structure of the first cutting tool 2 and the first drive component 3 as an example for explanation.

[0034] Reference Figure 1 A loading assembly 6 is provided on one side of the cutting platform 1, and the profile to be cut is transported to the cutting platform 1 through the loading assembly 6 to realize automatic loading; a discharging assembly 8 is provided on the other side of the cutting platform 1, and the profile after cutting is transported and unloaded through the discharging assembly 8. The first rotating plate 11 is located between the second rotating plate 12 and the loading assembly 6, so that the automatic loading of the profile can be realized through the loading assembly 6, and the profile transported to the cutting platform 1 by the loading assembly 6 will first reach the first rotating plate 11, so that the first cutting tool 2 on the first rotating plate 11 can cut the profile.

[0035] Reference Figure 1 and Figure 2The first cutting tool 2 includes a mounting seat 21 fixedly connected to the first rotating plate 11, a mounting plate 22 rotatably connected to the mounting seat 21, and a cutter 23 rotatably connected to the mounting plate 22, wherein the cutter 23 is disc-shaped, and the outer circumferential surface of the cutter 23 is a serrated blade, and a cutting motor 24 for driving the cutter 23 to rotate is also fixedly connected to the mounting plate 22. The first driving assembly 3 is connected to the mounting plate 22 to drive the mounting plate 22 to rotate through the first driving assembly 3, so that the first driving assembly 3 can drive the cutter 23 to rotate around the hinge axis of the mounting plate 22 and the mounting seat 21, so that the cutter 23 is close to the profile to cut the profile.

[0036] Reference Figure 2 and Figure 3 A rotating motor 13 for driving the first rotating plate 11 to rotate is fixedly connected to the cutting platform 1. The rotating motor 13 can drive the first rotating plate 11 to rotate to adjust the position of the cutter 23. When the cutter 23 is in the initial state, the first driving component 3 drives the mounting plate 22 to rotate around the hinge axis with the mounting seat 21, and the cutter 23 can be driven to cut the profile on the cutting platform 1, so as to cut the profile. After the profile is cut, as the profile continues to move, after the profile moves to the direction of the unloading component 8 by a set length, the rotating motor 13 also drives the first rotating plate 11 to rotate a set angle, so that the cutter 23 and the profile are placed at a set angle. At this time, the hinge axis of the mounting plate 22 and the mounting seat 21 is driven to rotate by the first driving component 3, and the end of the profile can be cut and chamfered by the cutter 23.

[0037] Among them, in order to limit the rotation angle of the first rotating plate 11, a first encoder for detecting the rotation amount of the output shaft of the rotating motor 13 is installed on the output shaft of the rotating motor 13. The first encoder is connected to the rotating motor 13 through a controller, so that when the rotation amount of the output shaft of the rotating motor 13 reaches a set value, the controller controls the rotating motor 13 to stop. The rotation amount of the output shaft of the rotating motor 13 can be controlled by the first encoder, so that the rotating motor 13 can drive the cutter 23 to rotate to be perpendicular to the profile to cut the profile, or drive the cutter 23 to rotate to a set angle with the profile to cut and chamfer the profile.

[0038] However, when the cutter 23 is perpendicular to the profile, the distance between the output shaft of the rotating motor 13 and the profile is different from the distance between the output shaft of the rotating motor 13 and the profile when the cutter 23 and the profile are at a set angle, so the mounting plate 22 is set as a telescopic plate.

[0039] Specifically, the mounting plate 22 includes a first plate 221 rotatably connected to the mounting seat 21, a second plate 222 slidably connected to one end of the first plate 221 away from the mounting seat 21, and an electric push rod 223 fixedly connected between the first plate 221 and the second plate 222, and a sliding groove 224 for the electric push rod 223 to be embedded is provided at one end of the first plate 221 away from the mounting seat 21. A linear displacement sensor is also installed on the electric push rod 223, the body of the linear displacement sensor is fixedly connected to the body of the electric push rod 223, and the sliding sheet of the linear displacement sensor is fixedly connected to the push rod of the electric push rod 223, so that the extension and contraction amount of the electric push rod 223 is detected by the linear displacement sensor to control the overall extension and contraction length of the mounting plate 22. Among them, the linear displacement sensor and the electric push rod 223 are both connected to the controller, so that when the rotating motor 13 drives the first rotating plate 11 to rotate a set angle, the electric push rod 223 also extends, and the linear displacement sensor detects the extension amount of the electric push rod 223 and transmits the detected data to the controller in real time. When the detection value of the linear displacement sensor received by the controller reaches the set value, the electric push rod 223 is controlled to stop, ensuring that no matter how many degrees the first rotating plate 11 rotates, the cutter 23 can accurately cut the profile located on the cutting platform 1.

[0040] Reference Figure 2 The first driving assembly 3 includes a driving motor 31 fixed to the first rotating plate 11, a rotating disk 32 fixed to the output shaft of the driving motor 31, and a connecting rod 33 rotatably connected to the rotating disk 32 away from the driving motor 31. The connecting rod 33 is hinged on the mounting plate 22, and the rotation axis of the connecting rod 33 and the rotating disk 32 is staggered with the axis of the output shaft of the driving motor 31, so that a crank rocker mechanism is formed between the rotating disk 32, the connecting rod 33, and the mounting plate 22. When the driving motor 31 is started to drive the rotating disk 32 to rotate, one end of the connecting rod 33 performs a circular motion around the axis of the output shaft of the driving motor 31, and the other end of the connecting rod 33 drives the mounting plate 22 to rotate around the hinge axis with the mounting seat 21 through the driving rod, so that the mounting plate 22 swings back and forth, thereby driving the cutter 23 installed on the mounting plate 22 to swing back and forth to achieve cutting of the profile. When the profile needs to be cut, the driving motor 31 only needs to drive the rotating disk 32 to rotate one circle. At this time, the connecting rod 33 can drive the mounting plate 22 to swing back and forth once, and when the mounting plate 22 swings to cut the profile, the cutting motor 24 also drives the cutter 23 to rotate, making the cutting of the profile smoother.

[0041] In order to control the rotation amount of the drive motor 31, a second encoder is installed on the output shaft of the drive motor 31, and the rotation amount of the output shaft of the drive motor 31 can be controlled by the second encoder. The drive motor 31 and the second encoder are both connected to the controller, so that when the drive motor 31 is controlled to start, the second encoder detects the rotation amount of the output shaft of the drive motor 31, and transmits the detected data to the controller in real time. When the data detected by the second encoder received by the controller reaches the set value, the controller controls the drive motor 31 to stop, so as to achieve precise control of the drive motor 31 for each rotation.

[0042] At the same time, in order to ensure that when the mounting plate 22 swings relative to the mounting seat 21, it can smoothly drive the cutter 23 to cut the profile, the second plate 222 is set to be L-shaped as a whole, and the L-shaped opening of the second plate 222 is set toward the cutting platform 1, so that when the mounting plate 22 rotates relative to the mounting seat 21, the cutter 23 can be smoothly rotated to the profile of the cutting platform 1 to cut the profile.

[0043] Reference Figure 1 and Figure 4 In order to prevent the cutter 23 from contacting the cutting platform 1 and damaging the cutting platform 1 and the cutter 23 during the process of cutting the profile, an avoidance groove 14 for the cutter 23 to be embedded is provided on the cutting platform 1, and a plurality of avoidance grooves 14 can be radially arranged around the rotation axis of the first rotating plate 11. Since the commonly used chamfers for chamfering profiles are 30 degrees, 45 degrees and 60 degrees, in the present application, the cutting platform 1 is provided with avoidance grooves 14 embedded when the cutter 23 cuts the profile at 30 degrees, and avoidance grooves 14 embedded when the profile is chamfered at 30 degrees, 45 degrees and 60 degrees respectively. Since the second cutting tool 4 is used to chamfer the other end of the profile, three avoidance grooves 14 for the second cutting tool 4 to be embedded are opened on the cutting platform 1, corresponding to the positions of the second cutting tool 4 when it is rotated 30 degrees, 45 degrees and 60 degrees respectively, and the direction of the avoidance groove 14 for the second cutting tool 4 to be embedded is opposite to the direction of the avoidance groove 14 for the first cutting tool 2 to be embedded.

[0044] Reference Figure 1 and Figure 4 A detection component 7 is provided on the cutting platform 1 for detecting whether the profile reaches a set position of the cutting platform 1 .

[0045] Specifically, the detection assembly 7 includes a first fixed plate 71 fixedly connected to the cutting platform 1, a second fixed plate 72 fixedly connected to the cutting platform 1, an infrared transmitter 73 fixedly connected to the first fixed plate 71 on the side facing the second fixed plate 72, and an infrared receiver 74 fixedly connected to the second fixed plate 72 on the side facing the first fixed plate 71. A sliding space for the profile to pass through is formed between the first fixed plate 71 and the second fixed plate 72. Under normal conditions, the infrared receiver 74 can receive the signal emitted by the infrared transmitter 73. When the profile is transported to the cutting platform 1 by the feeding assembly 6, the profile will slide out of the sliding space and block the signal emitted by the infrared transmitter 73 to the infrared receiver 74. At this time, it can be detected whether the profile has reached the set position of the cutting platform 1.

[0046] The feeding assembly 6 includes a feeding frame 61, a conveyor belt 62 installed on the feeding frame 61, and a feeding motor 63 for driving the conveyor belt 62. The feeding motor 63 can drive the conveyor belt 62 to transmit the profile to the cutting platform 1. A third encoder is installed on the output shaft of the feeding motor 63, and the third encoder can collect the rotation amount of the output shaft of the feeding motor 63 to obtain the moving distance of the profile.

[0047] Among them, the driving motor 31, the feeding motor 63, the third encoder, and the infrared receiver 74 are all connected to the controller. When the signal received by the infrared receiver 74 is blocked, the controller can receive it, and then control the feeding motor 63 to rotate the set angle to transport the profile to the avoidance groove 14, and then the controller will control the driving motor 31 to rotate one circle, so that the profile is cut by the cutter 23. Then the feeding motor 63 is started, and the profile is driven to move the first set length through the belt 623. At this time, the rotating motor 13 also drives the first rotating plate 11 to rotate the set angle, and the electric push rod 223 also retracts the set length. Then the output shaft of the driving motor 31 rotates one circle, so that the cutter 23 cuts and chamfers the profile after moving the set distance. Then the belt 623 drives the profile to move the second set length, and the rotating motor 13 also drives the first rotating plate 11 to rotate in the opposite direction to reset the set angle, and the electric push rod 223 also retracts the set length. At this time, the controller will control the driving motor 31 to rotate one circle, so that the profile is cut by the cutter 23. Then the belt 623 drives the profile to continue moving the third set length. At this time, the controller controls the second drive assembly to drive the second cutting tool to move, so as to realize the chamfering of the other end of the cut profile, thereby completing the automatic processing of a section of the profile, and repeating the cycle in sequence until the cutting of all the profiles is completed.

[0048] Specifically, a first preset control and a second preset formula are stored inside the controller. Through the rotation angle of the first rotating plate 11, the controller can automatically calculate the extension and retraction data of the electric push rod 223 according to the first preset formula stored inside, so as to control the extension and retraction of the electric push rod 223; through the rotation angle of the first rotating plate 11, the controller can automatically calculate the first set length according to the second preset formula stored inside, so as to control the feeding motor 63 to rotate the set angle after the detection component 7 detects the profile to control the profile to move the first set length.

[0049] Reference Figure 4 When the cutter 23 is set to be perpendicular to the profile, the distance between the rotation axis of the mounting plate 22 and the side of the profile away from the mounting plate 22 is a; when the cutter 23 is set at an angle to the profile, the distance between the rotation axis of the mounting plate 22 and the side of the profile away from the mounting plate 22 is b, the line between a and b is c, and the angle between a and b is x. The value of x is the chamfer value of the profile to be cut, which is the set value, and the length of a is also the set value. cos x = a / b, b=a / cos x, and the length of b can be obtained. The telescopic amount of the electric push rod 223 is the difference between b and a, so the first preset formula is (a / cos x)-a.

[0050] And tan x=c / a, then c=a*tan x. When the cutter 23 is perpendicular to the profile, the distance between the cutter 23 and the detection component 7 is set to d, which is a fixed value, so the second preset formula is a*tan x+d, so that the value of the first set length can be automatically calculated.

[0051] The length of the profile to be cut is set to e, and the second set length is e+d.

[0052] The same method is used to set that when the cutter 23 in the second cutting tool 4 is perpendicular to the profile, the distance between the rotation axis of the mounting plate 22 and the side of the profile away from the mounting plate 22 is a1; when the cutter 23 is at a set angle to the profile, the distance between the rotation axis of the mounting plate 22 and the side of the profile away from the mounting plate 22 is b1, the line between a1 and b1 is c1, the angle between a1 and b1 is also x, and the length between a1 and the detection component 7 is set to g.

[0053] The same method as above can be used to obtain the length of c1, and the third set length is e+g-c1.

[0054] The above formulas are stored in the controller, and the lengths of a, a1, d and g are also stored in the controller. When in use, the values ​​of e and x are set in advance according to the length of the profile to be cut and the chamfer angle of the profile to be processed, and the automatic processing of the profile can be realized.

[0055] It can be understood that the first set length, the second set length and the third set length mentioned above are all calculated from the time when the detection component 7 detects the profile.

[0056] In order to ensure the accuracy of the profile movement driven by the loading assembly 6, refer to Figure 1 The conveyor belt 62 includes a first belt roller 621 rotatably connected to one end of the loading frame 61, a second belt roller 622 rotatably connected to the other end of the loading frame 61, a belt 623 sleeved on the first belt roller 621 and the second belt roller 622, and a push plate 624 fixed to the belt 623. The loading motor 63 is fixed to the loading frame 61, and the output shaft of the loading motor 63 is fixed to the first belt roller 621 / the second belt roller 622, so that the belt 623 is driven by the loading motor 63 for transmission. A plurality of push plates 624 are arranged at intervals in the length direction of the belt 623, and the distance between two adjacent push plates 624 is consistent with the length of the profile raw material, so that the profile to be cut can be embedded between the two push plates 624, and the push plate 624 pushes the profile to reach the cutting space, and the push plate 624 pushes the profile to move on the cutting platform 1.

[0057] Reference Figure 1 The unloading assembly 8 can use a belt conveyor, which is a prior art and will not be described in detail in this application. As long as the cut profiles can be transported, it can be used. A receiving box 91 is placed at the end of the unloading assembly 8 away from the cutting platform 1, so that the cut profiles are transported to the receiving box 91 by the unloading assembly 8, realizing automatic receiving operation.

[0058] A waste collection box 92 is also provided between the cutting platform 1 and the unloading assembly 8, so that the waste generated after cutting and chamfering the profile can be pushed by the profile to the unloading assembly 8 and fall into the waste collection box 92 under the action of gravity. Since the profile is relatively long, the profile can smoothly pass through the waste collection box 92 and reach the unloading assembly 8, so as to be transported by the unloading assembly 8 to the receiving box 91 for collection.

[0059] The implementation principle of the cutting device of the steel structure profile of the power tower in the embodiment of the present application is as follows: when in use, first set the values ​​of e and x according to the length of the profile to be cut and the chamfer angle of the profile to be cut, and then place the profiles to be cut one by one on the belt 623 in sequence by manual or automatic feeding, and make the profiles located between two adjacent push plates 624. Then, the belt 623 is driven by the feeding motor 63 to transmit, so as to convey the profile to the cutting platform 1. When the end of the profile reaches between the first fixed plate 71 and the second fixed plate 72, the profile will block the signal transmitted by the infrared transmitter 73 to the infrared receiver 74. At this time, the controller controls the value of the first set length calculated according to the formula stored internally, and controls the feeding motor 63 to stop after rotating the set number of circles according to the obtained value, and the rotating motor 13 also rotates the set number of circles, and the controller also controls the electric push rod 223 to extend the set length. Then, the driving motor 31 is controlled to start and rotate one circle to drive the cutter 23 to chamfer the end of the profile. Then the feeding motor 63 continues to rotate to drive the profile to move the second set length. At this time, the controller also controls the rotating motor 13 to rotate in the opposite direction to reset, and controls the electric push rod 223 to retract the set length to reset, and then controls the driving motor 31 to rotate one circle to drive the cutter 23 to cut the profile. Finally, the controller continues to control the feeding motor 63 to rotate a set number of circles, so that the profile moves the third set length. At this time, the second cutting tool 4 also cuts the other end of the profile into a chamfer. When the cutter 23 cuts the profile, the controller also controls the second section of the profile, and when the second section of the profile moves the first set length, the cutter 23 processes the chamfer of the profile, and the cycle is repeated in sequence, so that the cutting and chamfering of the profile can be automatically completed by the same device, which greatly reduces the labor intensity of the staff when cutting and chamfering, improves the chamfering accuracy, and the entire device is relatively simple and the cost is relatively low.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
