DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application.

[0020] In the application, the word "exemplary" is used to mean "serving as an example, illustration, or description". Any embodiment described in the present application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not described in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in the present application.
[0021] To facilitate understanding of the scheme of the present application, the spline curves and arrows used in the drawings are explained here: the components indicated by the spline curves without arrows are solid components, that is, components with solid structures; the components indicated by the spline curves with arrows are virtual components, that is, components without solid structures.
[0022] At present, milling machine processing centers cannot meet the requirements for making arc grooves of larger-sized plate units; There is a 30mm gap between the center of the milling groove and the center of the main weld, which will increase the welding deformation; The milling groove position has a great influence on ultrasonic nondestructive testing because it interferes with ultrasonic emission.
[0023] See also Figure 1-4 as well as Figure 7 and Figure 8 , a portable semi-automatic slot milling machine, comprising: Guide rail 1; A support frame, the support frame is slidably connected to the guide rail 1, a milling cutter disc 6 is provided on the support frame, the milling cutter disc 6 extends to the outside of the support frame, a milling blade 8 is provided on the milling cutter disc 6, and a power system is also provided on the support frame, and the power system is connected to the milling cutter disc 6; A lifting system is provided on the support frame and drives the power system and the milling cutter disc 6 to move up and down.
[0024] It can be understood that according to the construction drawing of the steel structure bridge, the distribution position of the drip groove is clearly defined, and the guide rail 1 positioning line is drawn on the surface of the milled groove solid component. Before drawing the line, the distance between the guide rail 1 and the drip groove needs to be calculated. After the distance data is obtained, the drip groove position edge line (inside or outside of the milling cutter disc 6) is drawn according to the construction drawing, and the guide rail 1 positioning edge line parallel to the drip groove position edge line and the guide rail 1 distance is drawn.
[0025] It can be understood that after the guide rail 1 is fixed, the protruding materials on the surface of the guide rail 1 and the milled groove component in the milling machine area are cleaned, and the support frame is installed by lifting and hanging to match the guide rail 1, and is installed in the working area from top to bottom with the guide rail 1 as the reference.
[0026] In some embodiments, the guide rail 1 is a linear guide rail 1. The support frame moves in a straight line along the guide rail 1 to perform the groove milling.
[0027] In some embodiments, the guide rail 1 is a curved guide rail 1, which realizes the curved milling groove of the round-trip axis (generating an arc along the X-axis toward the Z-axis direction and an arc toward the Y-axis direction); it can be adapted to multi-axis curve construction.
[0028] In some embodiments, the guide rail 1 is made of flexible magnesium-aluminum alloy.
[0029] It can be understood that the support frame is a hollow three-dimensional structure, which is the main body of the slot milling machine. A milling cutter disc 6 is provided on the support frame, and a milling blade 8 is installed on the milling cutter disc 6. The power system provides power to the milling blade 8 to realize rotating slot milling.
[0030] It can be understood that the lifting system drives the power system and the milling cutter disc 6 to move up and down, with the purpose of adjusting the required height in combination with the milling groove depth requirement.
[0031] It can be understood that since the slot milling machine body is in a mobile working state, according to the conventional milling cutter steering and travel force (the slot milling machine and the milled component form an up and down (Z axis) thrust at the moment of cutting, it is not conducive to the close fit between the blade and the component during the slot milling process of the slot milling machine, thereby directly affecting the walking stability and cutting stability. Therefore, the steering setting of the milling blade 8 of the present application is counterclockwise steering cutting, and a restraining force is formed between the travel direction, the cutting direction of the milling cutter disc 6, the gravity of the slot milling machine, and the component to be slotted. During the process of manual propulsion and continuous cutting, the slot milling machine and the component to be slotted are kept in real-time engagement, ensuring smooth travel during the slot milling operation.
[0032] In the technical solution of the present application, the slot milling machine of the present application forms a geometric frame of a stable structure, the power system provides power for the milling cutter disc 6, driving the milling blade 8 to rotate and mill the slot; it is slidably connected to the guide rail 1 through a support frame to generate a walking reference, and the whole body moves with the help of manpower; the lifting system drives the power system and the milling cutter disc 6 to move up and down, and adjusts the required height in combination with the milling slot depth requirements. The slot milling machine of the present application can be constructed as a whole after the whole bridge is assembled, with centralized procedures and high production efficiency. In addition, the present application also avoids the displacement deviation of the drip groove between the beam sections caused by the milling of unit parts and then the overall assembly and welding. Therefore, the present application has the advantages of convenient construction, quality assurance, and adaptability to multi-axis curved construction capabilities and effects in the processing technology of the drip grooves of steel structure bridges, and has the technical breakthrough value of bridge drip groove processing.

In this way, the two first frames 2, the two second frames 10 and the two third frames 16 form a hollow geometric frame with a stable structure, and other components are distributed and fixed based on the geometric frame. It can also be understood that the two first frames 2 are square plates, which are symmetrically arranged on the left and right. The upper parts of the two sides of the openings of the two square plates are blocked by the two second frames 10, and the lower parts of the two sides of the openings of the two square plates are blocked by the two third frames 16, forming a hollow geometric frame, wherein a gap is left between the second frame 10 and the third frame 16 on the same side, so as to facilitate the installation of other components and reduce the overall weight of the slot milling machine; the second frame 10 and the third frame 16 are both plate-shaped.
[0035] In some embodiments, the support frame is in a regular shape, such as a cuboid, a cube, a trapezoid or a pyramid. It is understood that the support frame may also be in an irregular shape, and the present application is not limited thereto.
[0036] In some embodiments, the first frame 2 , the second frame 10 , and the third frame 16 are all made of carbon steel.
[0037] It can be understood that the lifting platform 35 drives the power system and the milling cutter disc 6 to move up and down.
[0038] In some embodiments, the electrical box 31 is provided with a second switch 27 , a third switch 28 , a fourth switch 30 and an emergency stop button 29 ; the electrical box 31 is also provided with an input inlet, to which a power cord 32 is connected.
[0039] It can be understood that the second switch 27 is an overload protection switch, which ensures that the faulty circuit can be automatically cut off when a serious overload, short circuit, or pressure loss occurs in the circuit, thereby effectively protecting the electrical equipment; the third switch 28 is a convenient off button, which ensures convenient and quick operation when stopping in time; the fourth switch 30 is a convenient on button, which ensures convenient and quick operation when starting in time; the emergency stop button 29 ensures that all power supplies can be instantly pressed to shut down during an emergency to ensure safety.
[0040] In some embodiments, a high-current contactor is provided inside the electrical box 31, which can frequently switch on and off the high-current power supply, and at the same time has a power supply voltage loss release protection function, ensuring that the slot milling machine automatically shuts down in the event of a power supply voltage loss.
[0041] In some embodiments, according to the torque and speed requirements of the milling blade 8, a 380V\1.5KW asynchronous motor is equipped to match the front motor installation method to ensure the balance of the slot milling machine's weight.
[0042] In some embodiments, a fixed chassis 15 is fixedly connected between the first frame 2 below the lifting platform 35; The lifting platform 35 is threadedly connected with a lifting spiral guide rod 13, the lifting spiral guide rod 13 extends to the top of the fixed chassis 15, and a first handle 12 is provided at one end of the lifting spiral guide rod 13 away from the fixed chassis 15; The first frame 2 is provided with rectangular holes symmetrically arranged on the left and right sides, and a wedge-shaped rotating support positioning structure 36 is symmetrically arranged in each hole. Both ends of the lifting platform 35 are rectangular parallelepiped structures, and each rectangular parallelepiped structure corresponds to the wedge-shaped rotating support positioning structures 36 located in the hole.
[0043] It can be understood that there is a certain distance between the lifting platform 35 and the fixed chassis 15 , and the lifting spiral guide rod 13 is not connected to the fixed chassis 15 .
[0044] It can be understood that the lifting platform 35 and the motor 3 fixed on the lifting platform 35, and the milling cutter disc 6 fixedly connected to the motor 3 use the connecting line of the two rectangular structures as the axis to achieve a small upward and downward rotation in a fan shape, that is, lifting and lowering in a fan shape.
[0045] In some embodiments, a first perforation position is provided on the first frame 2 corresponding to the milling cutter disc 6, and the milling cutter disc 6 passes through the first perforation position and extends to the outside, and the space of the first perforation position is larger than the volume of the milling cutter disc 6 located in the first perforation position; a second perforation position is provided on the first frame 2 corresponding to the motor 3, and one end of the motor 3 extends to the outside of the second perforation position, and the space of the second perforation position is larger than the volume of the motor 3 located in the second perforation position, so that when the lifting platform 35 moves up and down, the motor 3 and the milling cutter disc 6 can move up and down smoothly.
[0046] Furthermore, the motor 3 extending to the outside of the support frame and the milling cutter disc 6 are located on the same side of the support frame.
[0047] In some embodiments, the first handle 12 is circular, square, triangular or parallelogram. It is understandable that the first handle 12 may also be an irregular shape, and the present application is not limited thereto.
[0048] In some embodiments, a counterweight 11 is disposed on the lifting platform 35 .
[0049] It can be understood that the first handle 12 is rotated clockwise until the bottom of the lifting spiral guide rod 13 and the fixed chassis 15 generate mutual thrust, and then the first handle 12 is continued to be rotated clockwise, so that the lifting platform 35 and the motor 3 on the lifting platform 35, the milling disc 6 connected to the motor 3 and the counterweight 11 are all fan-shaped. When the first handle 12 is rotated counterclockwise, the lifting platform 35 and the motor 3 on the lifting platform 35, the milling disc 6 connected to the motor 3 and the counterweight 11 are fan-shaped. It can also be understood that during the height adjustment, the lowest position of the milling blade 8 is mainly used as a reference point, and the required height is adjusted in combination with the milling groove depth requirement.
[0050] It can also be understood that first, the first handle 12 is rotated clockwise, the lifting platform 35, the milling cutter disc 6, the milling blade 8, the locking bolt 5, the motor 3 and the counterweight 11 are raised, so that the lowest point of the milling blade 8 leaves the surface of the washed groove component. After checking that the working position is correct, the fourth switch 30 (convenient power button) on the electrical box 31 is started. After starting the machine, the locking bolt 5, the milling cutter disc 6 and the milling blade 8 begin to rotate counterclockwise at a low speed of 700 revolutions per minute. At this time, the first handle 12 is rotated counterclockwise, and the lifting platform 35, the milling cutter disc 6, the milling blade 8, the locking bolt 5, the motor 3 and the counterweight 11 are synchronously descended to the required height at a speed of 0.5 mm per second. Then the operator uses his own arms to hold the top of the milling machine frame, and the travel speed is mainly based on the resistance to the milling operation depth and the forward movement (the counterthrust is about 5 kg) to move forward for milling.
[0051] In some embodiments, a second handle 39 is disposed on the top of the first frame 2. It is understood that the second handle 39 may be U-shaped, ring-shaped, T-shaped, or irregularly shaped, and the present application is not limited thereto.
[0052] In some embodiments, positioning baffles 14 are respectively disposed on both sides of the fixed chassis 15 , and the positioning baffles 14 extend to the location of the lifting platform 35 .
[0053] It can be understood that the positioning baffle 14 blocks the opening between the fixed chassis 15 and the lifting platform 35 to prevent the broken iron chips from entering the gap between the fixed chassis 15 and the lifting platform 35 .
[0054] In some embodiments, an iron cutting baffle 4 is provided on the first frame 2 on the side where the milling cutter disc 6 is located, and the iron cutting baffle 4 is arc-shaped and extends to the outside of the milling cutter disc 6; The bottom of the iron cutting baffle plate 4 extends to the bottom of the first frame 2, and a first iron cutting isolation brush 9 is provided at the bottom of the iron cutting baffle plate 4; A second iron cutting isolation brush 37 is provided at the bottom of the first frame 2 located on the side of the iron cutting baffle 4 close to the milling cutter disc 6; A third iron cutting isolation brush 38 is provided at the bottom of the third frame 16 away from one end of the second iron cutting isolation brush 37 .
[0055] It can be understood that the iron cutting baffle 4 is located outside the advancing direction of the milling cutter disc 6 and is arc-shaped.
[0056] It can be understood that the setting of the iron cutting baffle 4, the first iron cutting isolation brush 9, the second iron cutting isolation brush 37 and the third iron cutting isolation brush 38 prevents the iron cuttings from splashing onto the working surface of the milling machine in the direction of travel during the milling construction process, thereby affecting the stable movement of the milling machine.
[0057] See also Figure 7 , wherein the bottom of the support frame is surrounded by running wheels 33. It can be understood that the running wheels 33 are connected to the bottom of the support frame through a bracket 17, a bracket 2 34 and an axle pin 7.
[0058] It can be understood that since the groove milling machine of the present application is precision machining, it must move stably. In order to ensure the absolute size relationship between the walking wheel 33 and the steel component to be grooved, the bottom walking wheel 33 is designed to be a hard alloy wheel surface, forming a hard connection relationship with the steel component to be grooved, to avoid the walking wheel 33 from generating excessive vibration during operation and affecting the travel stability.
[0059] It can also be understood that the lifting platform 35, the motor 3 on the lifting platform 35, the milling disc 6 connected to the motor 3, and the counterweight 11 form a soft connection relationship with the main support frame. The vibration generated during the operation is mainly transmitted to the lifting platform 35. Since the motor 3 carried by the lifting platform 35, the milling disc 6 connected to the motor 3, and the counterweight 11 form a vibration amount confrontation relationship, the effect of reducing the vibration amount is achieved, and the resonance phenomenon of the entire slot milling machine is effectively avoided. Keep the dynamic operation process of the walking wheel 33 and the steel member being milled continuously move in harmony.
[0060] See also Figure 5 In some embodiments, a plurality of magnetic seats 21 are provided on the track, each of the magnetic seats 21 is fixed to a first bracket 23 by a fixing bolt 20, the first bracket 23 is fixed to the track by a connecting bolt 18, and a first switch 19 and a magnet 22 are also provided on the magnetic seat 21.
[0061] It can be understood that according to the positioning line of the guide rail 1 above, an angle ruler is used to assist in measuring the corresponding positioning line position inside the track, and the first switch 19 of the knob of the magnetic seat 21 of the guide rail 1 is rotated 90° clockwise to open and close the magnetic seat 21. The principle is: when the knob is rotated 90° clockwise, the magnet 22 is close to the internal contact, and the magnetic material near the contact will be attracted by the magnet 22, thereby generating magnetization and adsorbing on the surface of the milled groove component, so that the magnetic seat 21 and the milled groove component produce a magnetic attraction effect, which plays a role in positioning and fastening. When the knob is rotated 90° counterclockwise, the internal contact of the magnet 22 is disconnected, the magnetic material near the contact loses magnetization, and the magnetic seat 21 is disconnected. At this time, the magnetic seat 21 fixes the guide rail 1 according to the positioning line in sequence, and the track laying work is completed.
[0062] See also Figure 6 In some embodiments, a second bracket 25 is provided at the bottom of the first frame 2 near the guide rail 1, and a pin 24 is provided on the second bracket 25. A guide wheel 26 is connected to the lower end of the pin 24, and the guide wheel 26 is slidably connected to the track.
[0063] It can be understood that the pin shaft 24 with the guide wheel 26 , the second bracket 25 , and the side surface of the first frame 2 close to the guide rail 1 form an inverted U-shaped structure that cooperates with the guide rail 1 and slides on the guide rail 1 .
[0064] It can be understood that after the guide rail 1 is fixed, the protruding materials on the surface of the guide rail 1 and the milled groove component in the milling machine area are cleaned, and the support frame is installed in match with the guide rail 1 by lifting and hanging. It is installed in the working area from top to bottom with the guide rail 1 and the guide wheel as the reference. Normal operation is carried out based on the contact surface between the guide wheel and the guide rail 1.
[0065] In some embodiments, each of the first frames 2 is a structure that is small at the top and large at the bottom.
[0066] Exemplarily, the first frame 2 is a trapezoidal structure that is small at the top and large at the bottom. In this way, the entire slot milling machine is a stable pyramid-shaped structure that is small at the top and large at the bottom. The main purpose is to increase the bottom weight and conduct and offset the vibration inward under the action of the pyramid structure to provide walking stability.
[0067] The slot milling machine of the present application adopts a portable design, combined with the auxiliary condition that the track can be arranged in a curve, so it can realize the portable construction of the drip trough of the larger steel structure bridge (steel box beam) after the overall assembly. First, the slot milling machine of the present application replaces the current situation that the drip trough can only be processed by the traditional fixed milling machine; second, the track used by the slot milling machine of the present application can be arranged in a curve, and the curved slot can be milled along the axis (arcs are generated along the X-axis to the Z-axis direction and arcs are generated along the Y-axis direction), which is suitable for multi-axis curved construction; third, the slot milling machine of the present application can be constructed as a whole after the whole bridge is assembled, so it avoids the displacement deviation of the drip trough between the beam sections caused by the milling of unit parts and then the overall assembly and welding.
[0068] The basic concepts have been described above. Obviously, for those skilled in the art, the above detailed disclosure is only for example and does not constitute a limitation of the present application. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements and amendments to the present application.
