DETAILED DESCRIPTION OF THE INVENTION

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1: Please refer to Figures 1-5 , this embodiment discloses a steel structure edge milling machine, which includes a long bracket 6, a transmission 12, and a height adjustment component. A moving frame 10 that moves along the length direction of the long bracket 6 is installed on the side of the long bracket 6. A height-adjustable support 3 is installed on the top side of the moving frame 10 through the height adjustment component. A first motor 1 is installed on the top side of the support 3. The power output shaft of the first motor 1 is fixedly connected to the power input shaft of the transmission 12. A milling edge component is provided on the power output shaft of the transmission 12. The power output shaft and the power input shaft of the transmission 12 are parallel to each other. The transmission 12 is fixed on the first motor 1 or the support 3.

[0026] The milling edge component includes a rotating shaft 18, a universal joint 19, and a fixed seat 9 fixedly installed on the bottom side of the support 3. The power output shaft of the transmission 12 and one end of the rotating shaft 18 are connected through the universal joint 19. A coaxial milling cutter 13 is fixedly installed at the other end of the rotating shaft 18. The support 3 is located between the milling cutter 13 and the first motor 1. An installation seat 17 that rotates around the axis of the rotating shaft 18 is installed on the rotating shaft 18. An arc-shaped hole 16 is provided on the fixed seat 9. A sliding positioning member 14 is provided on the arc-shaped hole 16. The positioning member 14 is fixed on the installation seat 17. The positioning member 14 can drive the installation seat 17 to slide along the arc-shaped hole 16, and the positioning member 14 can fix the position of the installation seat 17.

[0027] A plurality of first adsorption components 20 are installed on the bottom side of the long bracket 6. A plurality of second adsorption components 21 are installed on the bottom side of the moving frame 10. A power component for driving the moving frame 10 to move along the length direction of the long bracket 6 is installed on the moving frame 10.

[0028] Further, the first adsorption component 20 is an electromagnet or a negative pressure suction cup. The second adsorption component 21 is an electromagnet or a negative pressure suction cup. An external power supply and a control switch cooperate to supply power to the electromagnet. An external negative pressure pump and a switching valve cooperate to enable the negative pressure suction cup to adsorb the steel structure. The bottom sides of the first adsorption component 20 and the second adsorption component 21 are located on the same plane.

[0029] Further, the ratio of the length of the long bracket 6 to the length of the moving frame 10 is 10.0 - 50.0:1.0. The moving frame 10 is located between the long bracket 6 and the fixed seat 9. The rotation plane of the rotating shaft 18 is perpendicular to the length direction of the long bracket 6.

[0030] Preferably, the mounting seat 17 is a bearing seat or a collar, the height adjustment assembly is a diamond jack, a hydraulic cylinder or a pneumatic cylinder, the power assembly is a hydraulic cylinder or a pneumatic cylinder, and the positioning member 14 is a screw.

[0031] The first motor 1, the electromagnet or the negative pressure suction cup used in the present invention are all common devices in the prior art, and their working modes, structures, and usage methods are all well-known technologies, which will not be elaborated here.

[0032] The working process and principle of this embodiment are as follows: The staff places both the long bracket 6 and the moving frame 10 on the top side of the steel structure. The staff makes the length direction of the long bracket 6 parallel to the side of the steel structure to be milled. The staff makes the positioning member 14 drive the mounting seat 17 to slide along the arc-shaped hole 16. When the rotating shaft 18 rotates to the set inclination angle, the staff fixes the position of the mounting seat 17 with the positioning member 14.

[0033] The staff adjusts the height adjustment assembly so that the milling cutter 13 moves in a direction perpendicular to the top side of the steel structure. The staff adjusts the distance between the long bracket 6 and the side of the steel structure to be milled. The above two adjustment operations make the milling cutter 13 located on the trajectory of the milling operation of the steel structure.

[0034] Initially, one end of the moving frame 10 is close to the long bracket 6. The staff makes the first motor 1 drive the milling cutter 13 to rotate through the transmission 12, the universal joint 19 and the rotating shaft 18.

[0035] The first adsorption assembly 20 on the long bracket 6 adsorbs on the steel structure, and the second adsorption assembly 21 on the moving frame 10 does not adsorb the steel structure. The power assembly drives the moving frame 10 to move along the length direction of the long bracket 6. The rotating milling cutter 13 performs milling operation on the side of the steel structure. When the staff observes that the moving distance of the moving frame 10 along the long bracket 6 is close to the length of the long bracket 6, the staff makes the second adsorption assembly 21 on the moving frame 10 adsorb on the steel structure, and the first adsorption assembly 20 on the long bracket 6 stops adsorbing the steel structure. The power assembly drives the long bracket 6 to move along the length direction of the long bracket 6 to change the position of the long bracket 6 on the steel structure. Then the staff makes the first adsorption assembly 20 on the long bracket 6 adsorb on the steel structure, and the second adsorption assembly 21 on the moving frame 10 stops adsorbing the steel structure. Repeat the above operation to realize continuous milling of the side of the steel structure.

[0036] This steel structure milling machine moves step by step on the steel structure. When milling the steel structure, it is not necessary to adjust the position of the steel structure, and there is no need for manual site cleaning or equipment position adjustment, which improves the milling efficiency of the steel structure.

[0037] This steel structure milling machine can achieve double-sided milling of the steel structure by adjusting the tilt angle of the rotating shaft 18 of this steel structure milling machine, reducing the energy consumption of flipping the steel structure without flipping the steel structure, avoiding errors caused by multiple positioning, and ensuring the symmetry and dimensional consistency of double-sided milling.

[0038] Preferably, at least one adsorption component one 20 is fixed at a position on the bottom side of the long bracket 6 away from the end of the long bracket 6, so that this steel structure milling machine can mill the end of the steel structure.

[0039] Furthermore, the transmission 12 enables the rotational speed of the milling cutter 13 to be adjustable, and this steel structure milling machine can adapt to different processing requirements, improving processing efficiency and accuracy.

[0040] Furthermore, when this steel structure milling machine is working, the center of gravity of this steel structure milling machine is located above the steel structure, preventing this steel structure milling machine from falling off the steel structure.

[0041] Furthermore, the staff draws the cross-sectional shape of the position to be milled on the end face of the steel structure, facilitating the staff to adjust the position of the milling cutter 13 according to the cross-sectional shape of the position to be milled.

[0042] Embodiment 2: As Figures 1-5 shown, this embodiment discloses a steel structure milling machine, whose structure is substantially the same as that of Embodiment 1.

Openings are provided in the elastic pads 15 corresponding to the positions of the adsorption component one 20 or the adsorption component two 21, and the elastic pads 15 are elastic rubber pads or elastic silica gel pads.

[0043] The working process and principle of this embodiment are: During the movement of the long bracket 6 and the moving bracket 10 on the top side of the steel structure, the elastic pads 15 push aside sundries such as iron filings, stones, and rust on the surface of the steel structure, reducing the influence of the sundries on the movement of the adsorption component one 20 or the adsorption component two 21.

[0044] Furthermore, the staff sprays water on the surface of the steel structure, and a thin water film is filled between the elastic pads 15 and the steel structure. The elastic pads 15 and the thin water film increase the adsorption force between the long bracket 6 and the steel structure, preventing the long bracket 6 from shifting.

[0045] Embodiment 3: As Figure 1 、 Figure 3 and Figure 5 shown, this embodiment discloses a steel structure milling machine, whose structure is substantially the same as that of Embodiment 2. The difference is that adjusting frames 8 with adjustable extended lengths are fixed at both ends of the long bracket 6 in the length direction in this embodiment, and rotating rollers 7 are installed on each adjusting frame 8.

[0046] Further, a sliding block is provided on the adjusting frame 8. The sliding block is fixed on the long bracket 6, and a bolt or a clamp for positioning the adjusting frame 8 is installed on the sliding block.

[0047] The working process and principle of this embodiment are as follows: When the steel structure milling machine mills the steel structure, the rotating roller 7 abuts against the side of the steel structure to prevent the long bracket 6 from rotating on the steel structure.

[0048] Embodiment 4: As Figure 1 , Figure 3 and Figure 5 shown, this embodiment discloses a steel structure milling machine, whose structure is substantially the same as that of Embodiment 1. The difference is that the height adjustment assembly of this embodiment includes a screw rod 1 and a guide rod 22 arranged in parallel. A threaded hole adapted to the screw rod 1 is provided on the support 3. The screw rod 1 passes through the threaded hole. One end of the screw rod 1 is connected to the top side of the moving frame 10 through a bearing. One end of the guide rod 22 is fixedly connected to the top side of the moving frame 10, and the other end of the guide rod 22 penetrates through the support 3 and extends outside the support 3. The guide rod 22 enables the support 3 to move along the length direction of the guide rod 22.

[0049] The working process and principle of this embodiment are as follows: The staff rotates the screw rod 1 forward or backward, thereby adjusting the distance between the support 3 and the moving frame 10.

[0050] Preferably, a plurality of distance scales are provided on the guide rod 22 along its length direction to facilitate measuring the distance between the support 3 and the moving frame 10.

[0051] Embodiment 5: As Figure 1 and Figure 3 shown, this embodiment discloses a steel structure milling machine, whose structure is substantially the same as that of Embodiment 1. The difference is that the power assembly of this embodiment includes a motor 2 11 fixed on the moving frame 10. A gear 4 is coaxially fixed on the power output shaft of the motor 2 11. A rack 5 is fixed on the top side of the long bracket 6. The gear 4 meshes with the rack 5.

[0052] Further, the motor 2 11 is a stepper motor, a servo motor or a servo motor, and an external power supply and a control switch cooperate to supply power to the motor 2 11.

[0053] The working process and principle of this embodiment are as follows: The staff can control the forward or reverse rotation of the motor 2 11. The motor 2 11 makes the moving frame 10 move relative to the long bracket 6 through the gear 4 and the rack 5.

[0054] Furthermore, position sensors commonly used in the prior art are installed at both ends of the long bracket 6 corresponding to the positions of the moving frame 10. The first motor 1, the second motor 11, the first adsorption assembly 20, the second adsorption assembly 21, and the two position sensors are all electrically connected to an external PLC controller. The PLC controller measures the position of the moving frame 10 through the position sensors, enabling this steel structure edge milling machine to continuously mill the edges of the steel structure under the control of the PLC controller, reducing the labor intensity of the staff and improving the intelligent level of edge milling.

[0055] Embodiment Six: As Figure 3 and Figure 4 shown, this embodiment discloses a steel structure edge milling machine, whose structure is substantially the same as that of Embodiment One. The difference lies in that the positioning member 14 of this embodiment includes a second screw 141. One end of the second screw 141 is fixedly connected to the mounting seat 17, and a nut 142 is installed at the other end of the second screw 141. The second screw 141 passes through the arc-shaped hole 16, and the fixed seat 9 is located between the nut 142 and the mounting seat 17.

[0056] The working process and principle of this embodiment are as follows: The staff makes the second screw 141 drive the mounting seat 17 to slide along the arc-shaped hole 16. When the rotating shaft 18 rotates to the set inclination angle, the staff rotates the nut 142 to fix the position of the mounting seat 17.

[0057] Furthermore, several angle scales are provided at the position of the fixed seat 9 close to the arc-shaped hole 16 to facilitate determining the inclination angle of the rotating shaft 18.
