Description

Technical Field

[0001] The invention relates to the technical field of contact network accessories processing equipment, in particular to a contact network punching bracket device. Background Art

[0002] The overhead rigid contact network is an important component of the subway electric traction system. Its main function is to provide a stable power supply for subway trains. Its working principle is based on the power transmission between the pantograph and the contact network. The pantograph contacts the contact network wire through the slide, and transmits power to the traction motor of the train to drive the train forward. The overhead rigid contact network has many advantages, such as compact structure, convenient construction, low maintenance cost, and long service life. The suspension channel steel of the overhead rigid contact network requires the use of drilling equipment during the processing process. The drilling equipment is used to open holes in the suspension channel steel so that the suspension channel steel can be bolted and fixed to the installation plane, thereby supporting the suspension system of the contact network and maintaining the height and tension of the contact network.

[0003] For example, Chinese invention patent CN111468758A discloses an auxiliary device for positioning the holes in channel steel. According to the number of holes to be punched in the channel steel and the distance between the two holes, the positioning slider is inserted into the transverse scale and fixed with the set screw. Then, the distance between the mounting plate and the positioning plate is adjusted according to the width of the channel steel. The bracket is difficult to operate and has poor support stability.

[0004] For example, Chinese invention patent CN109332759A, which belongs to the field of construction technology, specifically relates to a lever-type roof drilling electric drill bracket and its construction method. The electric drill bracket includes a support vertical rod, a joystick, and a lifting vertical rod; the bottom of the support vertical rod is supported on the foundation surface and is provided with a first horizontal crossbar and a second horizontal crossbar. This drilling bracket has low drilling accuracy and is difficult to drill.

[0005] The existing drilling technology and device operation method of the suspended channel steel of the overhead rigid contact network are basically the same, that is, the lifting and movement of the drilling rig is controlled by a lifting device. However, after the suspension channel steel of the overhead rigid contact network is drilled using a bracket, tooling and drilling equipment, the waste generated during the drilling process will be retained on the bracket and tooling, requiring staff to clean and maintain them from time to time. However, since the waste accumulates quickly and the cleaning work requires manual participation, it is easy to cause untimely or inadequate cleaning, resulting in waste accumulation. This not only increases the workload of the operator, but may also cause the waste to fall due to excessive accumulation, causing the equipment lifting device to become stuck, affecting the efficiency and quality of drilling.

[0006] Furthermore, if the position of the suspension channel steel is offset before the contact network suspension channel steel is punched, it will not only increase the difficulty of clamping, but also reduce the subsequent punching accuracy, thereby affecting the subsequent use quality of the suspension channel steel.

[0007] At the same time, when drilling holes in the side wall of the suspension channel steel, a thrust will be applied to the inner wall of the suspension channel steel, which will cause the position of the suspension channel steel to shift, and ultimately affect the subsequent drilling quality.

[0008] When the width of the suspension channel steel changes, the position of the waste chips generated after drilling changes accordingly. If the waste chips are still scraped and cleaned according to the initial position, the complete and effective recovery of the waste chips cannot be achieved, and it will affect the subsequent drilling of the suspension channel steel. Summary of the Invention

[0009] The purpose of the present invention is to provide a catenary drilling bracket device to solve the problems raised in the above background technology.

Detailed implementation manners

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

[0039] By Figures 1 to 9Given that, the present invention includes a suspension bracket 1. On both sides of the top of the suspension bracket 1, C-port crossbeams 4 are provided. The two C-port crossbeams 4 are symmetrically arranged and the openings are in both side directions. Inside both of the two C-port crossbeams 4, there are sprocket-type single-sided multi-point positioning modules 5 for fixing the catenary suspension channel steel workpieces to be drilled. Between the two sprocket-type single-sided multi-point positioning modules 5 is the workpiece clamping area. Then, the sprocket-type single-sided multi-point positioning modules 5 clamp and fix both sides of the suspension channel steel. On the top of the suspension bracket 1 on one side of the C-port crossbeam 4, there is a completely penetrating waste discharge port 2, and the waste discharge port 2 is for discharging the waste chips generated during drilling. Since the suspension channel steel has a large size and weight, and the suspension bracket 1 has sufficient load-bearing capacity and stability to prevent the workpiece from sinking or tilting.

[0040] On one outer wall of the suspension bracket 1, there is a double-rack pushing module 3 for driving the two sprocket-type single-sided multi-point positioning modules 5 to work synchronously and clamp the catenary suspension channel steel workpieces. The double-rack pushing module 3 continuously moves above the suspension bracket 1 and drives the sprocket-type single-sided multi-point positioning modules 5 to work and clamp the suspension channel steel.

[0041] On the top of both of the two C-port crossbeams 4, there are longitudinal beams 7. The extending direction of the longitudinal beams 7 is perpendicular to the extending direction of the C-port crossbeams 4. At both ends of the surfaces of the two longitudinal beams 7, sliding plates 8 are slidably installed. At the bottom of the sliding plates 8, there are limiting grooves, and at the top of the longitudinal beams 7, there are limiting blocks. The limiting blocks and the limiting grooves are in limiting sliding connection. Then, the sliding plates 8 can stably move horizontally on the top of the longitudinal beams 7. On one outer wall of the sliding plates 8 close to the sprocket-type single-sided multi-point positioning modules 5, there are scraping plates 10. The scraping plates 10 can not only position and support the suspension channel steel during drilling, but also scrape and clean the waste chips on the top of the suspension bracket 1 to ensure the stability of subsequent drilling of the suspension channel steel. On one outer wall of one of the sliding plates 8, there is a Z-axis lifting drive module 11 for controlling the height of the scraping plate 10. The Z-axis lifting drive module 11 drives the scraping plate 10 to move up and down and adjusts the supporting and scraping heights.

[0042] On one side of the top of both of the two C-port crossbeams 4, there are convex plates 6. On one outer wall of the convex plates 6 close to the longitudinal beams 7, there is a connecting rod pushing structure 9 for driving the sliding plates 8 and the scraping plates 10 to slide in the Y-axis direction. Between the connecting rod pushing structure 9 and the sprocket-type single-sided multi-point positioning module 5, there is a bevel gear transmission structure 902 for maintaining power transmission. The sprocket-type single-sided multi-point positioning module 5 works and drives the connecting rod pushing structure 9 to work through the bevel gear transmission structure 902.

[0043] At the bottom of the suspension bracket 1 below the waste discharge port 2, there is a discharge channel 101. At the bottom end of the discharge channel 101, there is an opening. The connecting rod pushing structure 9, the sliding plates 8, and the scraping plates 10 are used to discharge the waste chips remaining on the surface of the suspension bracket 1 into the waste discharge port 2 and the discharge channel 101.

[0044] The sprocket - type single - side multi - point positioning module 5 includes a number of equally - spaced rotating shafts 501 rotatably installed inside the C - port cross - frame 4, a stopper 502 fixed to one end of the surface of the rotating shaft 501, and a sprocket drive structure 504 installed at the top of the rotating shaft 501. A driven gear 503 is provided at one end of the surface of one of the rotating shafts 501. The sprocket drive structure 504 is used to connect the other rotating shafts 501 in the X - axis direction and rotate them synchronously. The use of the sprocket drive structure 504 ensures that the rotating shafts 501 do not slip during rotation, guaranteeing the stable transmission of rotational power.

[0045] After the catenary suspension channel steel to be processed is placed on the suspension bracket 1, the controller activates the double - rack pushing module 3. The double - rack pushing module 3 drives the driven gears 503 in the two sprocket - type single - side multi - point positioning modules 5 to rotate synchronously. Then, the driven gears 503 drive the rotating shafts 501 to rotate. During this process, the other rotating shafts 501 in the same X - axis direction rotate synchronously under the drive of the sprocket drive structure 504. Then, the rotating shafts 501 drive the stoppers 502 to swing towards the vertical central reference plane of the suspension bracket 1, that is, the stoppers 502 exert a force on one outer wall of the catenary suspension channel steel, so that the catenary suspension channel steel can be clamped and fixed by the stoppers 502.

[0046] An elastic friction block 5022 is provided on one outer wall of the stopper 502 close to the vertical central reference plane of the suspension bracket 1. The elastic friction block 5022 has elasticity. The elastic friction block 5022 gradually inclines towards the vertical central reference plane of the suspension bracket 1 from bottom to top. The setting of the elastic friction block 5022 can enable the outer wall surface and the bottom edge of the suspension channel steel to be stressed simultaneously, that is, both the horizontal direction and the Z - axis direction of the suspension channel steel are stressed, helping the suspension channel steel to be better fixed and limited.

[0047] Through the support of multiple positioning points, the weight of the workpiece can be more evenly distributed, avoiding offset or instability caused by single - point positioning. Especially when processing workpieces like suspension channel steel with large weight and irregular shapes, this multi - point support system can greatly improve the processing accuracy. At the same time, multi - point positioning can provide balanced support force to ensure that the workpiece does not deform during processing.

[0048] The double-rack pushing module 3 includes a cylinder frame 301 fixed on the outer wall of one side of the suspension bracket 1, a first cylinder 302 installed inside the cylinder frame 301, and a connecting beam 303 fixed to the top end of the piston rod of the first cylinder 302. Two mirror-symmetrical rack monomers 304 are installed on the outer wall of the connecting beam 303 close to the C-port cross beam 4. The driven gears 503 and the rack monomers 304 mesh with each other. The rotating shaft 501 drives the connecting rod pushing structure 9 to work through the bevel gear transmission structure 902. The first cylinder 302 drives the connecting beam 303 and the two rack monomers 304 to slide in the X-axis direction. Since the two rack monomers 304 are mirror-symmetrical, each rack monomer 304 drives one driven gear 503 to rotate, so as to force the sprocket-type single-sided multi-point positioning module 5 to act. Compared with motor-driven equipment, etc., the structure of the double-rack pushing module 3 can better balance the mechanical load during the transmission process and avoid dragging or jumping phenomena caused by uneven transmission, thereby ensuring the stable clamping of the suspended channel steel workpiece.

[0049] A notch 5021 is provided on the outer wall of the abutting block 502 close to the rack monomer 304. The notch 5021 is for the rack monomer 304 to horizontally slide in the X-axis direction. Concave openings 401 are provided on the outer walls of the two C-port cross beams 4 close to the connecting beam 303. The setting of the notch 5021 can allow the rack monomer 304 to slide, avoiding movement jamming caused by the X-axis sliding of the rack monomer 304 and the yaw of the abutting block 502, and the setting of the concave opening 401 can allow the connecting beam 303 to slide in the X-axis, promoting the stable cooperation of the double-rack pushing module 3 and the sprocket-type single-sided multi-point positioning module 5.

[0050] The Z-axis lifting drive module 11 includes a U-shaped seat 1101 fixed to the bottom end of one of the sliding plates 8, a second cylinder 1102 installed at the bottom end of the U-shaped seat 1101, and a sliding table 1103 slidably installed on the outer wall of one side of the sliding plate 8. A convex arm 1105 connected to the top end of the piston rod of the second cylinder 1102 is provided at one end of the sliding table 1103. The other end of the sliding table 1103 is fixedly connected to the outer wall of one side of the scraping plate 10. A guide post 1104 is provided inside one of the sliding tables 1103, and one end of the guide post 1104 penetrates to the outside of the other sliding table 1103.

[0051] After the catenary suspension channel steel workpiece is processed and removed from between the two symmetrical sprocket-type single-sided multi-point positioning modules 5, the controller controls the Z-axis lifting drive module 11 to operate. Then, the second cylinder 1102 drives the convex arm 1105, one of the sliding tables 1103, and the scraping plate 10 to move downward. Since the sliding table 1103 is slidably connected to another sliding table 1103 through the guide post 1104, the two sliding tables 1103 and the two scraping plates 10 in the Y-axis direction can move downward driven by the second cylinder 1102 until the bottom edge of the scraping plate 10 contacts the upper surface of the suspension bracket 1, thus facilitating the subsequent forward movement of the connecting rod pushing structure 9 to push the scraping plate 10, the sliding of the sliding plate 8, and the removal of waste chips.

[0052] The connecting rod pushing structure 9 includes a central shaft 901 rotatably installed inside the convex plate 6, a connecting plate 903 fixed to one end of the central shaft 901, an electric telescopic rod 905 on one side of the connecting plate 903, and a fish-eye connecting rod 904 hingedly installed on the outer wall of one side of the sliding plate 8. The end of the fish-eye connecting rod 904 away from the sliding plate 8 is hinged to the output end of the electric telescopic rod 905, and the other end of the central shaft 901 is kept in power connection with the rotating shaft 501 through the bevel gear transmission structure 902.

[0053] After the Z-axis lifting drive module 11 controls the scraping plate 10 to contact the suspension bracket 1, the controller activates the double-rack pushing module 3. When the double-rack pushing module 3 drives one of the rotating shafts 501, the rotating shaft 501 drives the central shaft 901 in the convex plate 6 to rotate through the bevel gear transmission structure 902. Then, the rotational movement of the connecting plate 903 and the electric telescopic rod 905 is converted into the Y-axis sliding movement of the sliding plate 8, the sliding table 1103, and the scraping plate 10 through the fish-eye connecting rod 904. Subsequently, the scraping plate 10 pushes the waste chips remaining on the surface of the suspension bracket 1 towards the waste discharge port 2, so that the waste chips enter the discharge channel 101. This enables the waste chip cleaning process to be carried out without manual intervention, reducing the time and labor intensity of manual cleaning.

[0054] After the cleaning is completed, the Z-axis lifting drive module 11 controls the scraping plate 10 to move away from the suspension bracket 1 again to prevent the scraping plate 10 from hindering the subsequent clamping operation of the sprocket-type single-sided multi-point positioning module 5.

[0055] Before the operation of the embodiment of the present application, initially, multiple abutting blocks 502 and the scraping plate 10 are in their initial positions. That is, the output end of the second air cylinder 1102 is at its maximum value. The second air cylinder 1102 drives the convex arm 1105 to move upward. The convex arm 1105 drives the scraping plate 10 to move upward through the sliding table 1103 and the guiding column 1104 and reaches the maximum value. The height value of the scraping plate 10 is greater than the height value of the C-port cross beam 4, thereby avoiding the influence of the scraping plate 10 on the blanking of the suspended channel steel. The output end of the electric telescopic rod 905 is at its minimum value. The electric telescopic rod 905 drives the scraping plate 10 to be in its initial position through the fish-eye connecting rod 904 and the sliding plate 8. The distance between the two scraping plates 10 is greater than the width value of the suspended channel steel. Then, the staff places the catenary suspended channel steel to be processed on the suspension bracket 1, and the opening of the suspended channel steel faces upward. The suspension bracket 1 is the basic equipment for supporting the suspended channel steel workpiece, providing a stable platform to ensure that the workpiece will not move due to gravity or external force during the processing.

[0056] Next, the staff activates the double-rack pushing module 3. The double-rack pushing module 3 can drive the two sprocket-type single-sided multi-point positioning modules 5 to act synchronously. During this process, the two sprocket-type single-sided multi-point positioning modules 5 clamp the suspended channel steel at multiple symmetric positioning points. Each sprocket-type single-sided multi-point positioning module 5 is equipped with multiple positioning points, and these positioning points are evenly distributed, which can effectively avoid the position deviation or deformation of the workpiece during the processing and avoid the deficiencies of the traditional single clamping point.

[0057] During this process, due to the different positions of the suspended channel steel on the suspension bracket 1, the distance values detected by the distance sensors 12 are different. If the distance value detected by one side of the distance sensor 12 is greater than the set distance preset value, and the distance value detected by the other side of the distance sensor 12 is less than the set distance preset value, it means that the suspended channel steel has shifted and is close to the side where the distance value detected by the distance sensor 12 is smaller. At this time, in order to quickly and effectively correct the position of the suspended channel steel, the controller first controls the output ends of the two electric telescopic rods 905 to extend, and the extension distance of the output end of the electric telescopic rod 905 on the side where the distance value detected by the distance sensor 12 is greater is greater than the extension distance of the output end of the electric telescopic rod 905 on the side where the distance value detected by the distance sensor 12 is smaller. The electric telescopic rod 905 drives the scraping plate 10 to move synchronously through the fish-eye connecting rod 904 and the sliding plate 8. At the same time, the second air cylinder 1102 is started synchronously and its output end shortens. The second air cylinder 1102 drives the convex arm 1105 to move downward. The convex arm 1105 drives the scraping plate 10 to move downward through the sliding table 1103 and the guiding column 1104. The scraping plate 10 moves downward and presses against the inner bottom of the opening of the suspended channel steel, thereby improving the subsequent positioning and clamping effect.

[0058] After that, the controller controls the first cylinder 302 to start and its output end to extend. The first cylinder 302 drives the two rack monomers 304 to move synchronously through the connecting beam 303. The rack monomers 304 mesh with the driven gear 503 and drive the rotating shaft 501 at the end to rotate. The rotating shaft 501 at the end drives the other multiple rotating shafts 501 to rotate synchronously through the multiple sprocket drive structures 504. The rotating shaft 501 drives the abutting block 502 to move towards the side wall end of the suspended channel steel, and then realizes the extrusion support for the side wall of the suspended channel steel through the elastic friction block 5022 at the end of the abutting block 502. At the same time, when the rotating shaft 501 rotates, it drives the central shaft 901 to rotate through the bevel gear drive structure 902. The central shaft 901 drives the connecting plate 903 to rotate. The connecting plate 903 drives the slide plate 8 to move horizontally through the electric telescopic rod 905 and the fish-eye connecting rod 904. The slide plate 8 drives the scraping plate 10 to move towards both sides inside the suspended channel steel. And because the extension distance of the electric telescopic rod 905 on the side with the larger distance value detected by the distance sensor 12 increases, when the connecting plate 903 rotates, it drives the slide plate 8 to move a larger distance through the electric telescopic rod 905 and the fish-eye connecting rod 904. The slide plate 8 drives the scraping plate 10 to move a larger distance. After the scraping plate 10 is in extrusion contact with the inner wall of the suspended channel steel, it drives the suspended channel steel to continuously move towards the end with the larger distance value detected by the distance sensor 12 on the top of the suspension bracket 1, thereby realizing the continuous precise positioning of the suspended channel steel on the top of the suspension bracket 1, and further ensuring the clamping stability and drilling accuracy of the suspended channel steel in the subsequent process.

[0059] As the suspended channel steel continuously moves on the top of the suspension bracket 1, the distance value detected by the distance sensor 12 continuously changes. The distance between the suspended channel steel and the side with the larger distance value detected by the distance sensor 12 continuously decreases. The distance value detected by the distance sensor 12 on this side continuously decreases, then the controller controls the output end of the electric telescopic rod 905 on this side to continuously decrease, thereby ensuring the pushing and positioning stability of the scraping plate 10 against the inner wall of the suspended channel steel. When the distance values detected by the distance sensors 12 on both sides are equal and equal to the set distance preset value, it means that the suspended channel steel is at the precise drilling position at this time. The controller controls the first cylinder 302 to stop working, and the multiple abutting blocks 502 and the scraping plate 10 cooperate to jointly clamp and position the suspended channel steel.

[0060] Once the suspended channel steel is stably fixed on the suspension bracket 1 and is precisely clamped through the positioning module, the staff can start to execute the processing task and complete the drilling operation on the suspended channel steel by using the drilling equipment. During this process, the sprocket-type single-sided multi-point positioning module 5 can keep the workpiece stationary, help the workpiece to be in the correct position, and avoid processing errors caused by workpiece displacement.

[0061] And before processing and drilling holes in the side wall of the suspended channel steel, the controller controls the second cylinder 1102 to start and its output end to extend. The second cylinder 1102 drives the convex arm 1105 to move upward. The convex arm 1105 drives the scraping plate 10 to move upward through the sliding table 1103 and the guide post 1104. The scraping plate 10 disengages from the extrusion contact with the inner bottom of the suspended channel steel, thereby avoiding the subsequent hole drilling position on the inner wall of the suspended channel steel, improving the subsequent drilling accuracy and efficiency. After the scraping plate 10 rises to a suitable position, the drilling equipment works horizontally in the inner cavity of the suspended channel steel and drills holes in the inner wall of the suspended channel steel. At this time, the height of the drilling equipment is positioned by means of the scraping plate 10, further ensuring the accuracy and uniformity of the drilling position.

[0062] During the hole drilling process of the drilling equipment, when the drilling equipment applies an extrusion distance to one side inner wall of the suspended channel steel, the waste chips formed after drilling the suspended channel steel can directly fall on the top of the suspension bracket 1 and are convenient for subsequent scraping and recycling of the waste chips. Under the action of this extrusion distance, the suspended channel steel moves synchronously. The outer side wall of the suspended channel steel squeezes the elastic friction block 5022 to move synchronously. The distance value detected by the distance sensor 12 on this side decreases, and the distance value detected by the distance sensor 12 on the other side increases. In this process, it is necessary to increase the reverse supporting force on the suspended channel steel to prevent the drilling equipment from driving the suspended channel steel to shift during the drilling process and affecting the drilling accuracy.

[0063] Then the output end of the first cylinder 302 of the controller continues to start and extend. The first cylinder 302 meshes with the driven gear 503 and drives the rotating shaft 501 to rotate. The rotating shaft 501 drives a plurality of abutting blocks 502 to move through the chain wheel transmission structure 504. The abutting blocks 502 drive the elastic friction block 5022 to move and increase the extrusion distance on the outer wall of the suspended channel steel. When the rotating shaft 501 rotates, it drives the central shaft 901 to rotate through the bevel gear transmission structure 902. The central shaft 901 drives the connecting plate 903 to rotate. At this time, the output end of the electric telescopic rod 905 on the side where the detected distance value by the distance sensor 12 increases extends. Then the connecting plate 903 on this side drives the sliding plate 8 to move a greater distance through the electric telescopic rod 905 and the fish-eye connecting rod 904. The sliding plate 8 drives the scraping plate 10 to move a greater distance. The thrust applied by the scraping plate 10 on the side where the detected distance value by the distance sensor 12 increases to the inner wall of the suspended channel steel increases, thereby increasing the reverse supporting force when the suspended channel steel is drilled, ensuring the stability and positioning of the suspended channel steel during the hole drilling by the drilling equipment, and preventing the suspended channel steel from shifting after a long time of hole drilling work and affecting the drilling quality.

[0064] When the hole drilling of the inner wall of the suspended channel steel is completed, the controller controls the first cylinder 302 to move in the reverse direction. At the same time, the electric telescopic rod 905 on the side where the detected distance value by the distance sensor 12 increases starts and its output end shortens. Then, through a plurality of abutting blocks 502 and the scraping plate 10, the suspended channel steel is driven back to the clamped state, and the above process is repeated to continuously carry out subsequent multiple hole drilling processes.

[0065] After the suspension channel steel is processed, the controller starts the double-rack pushing module 3 and the Z-axis lifting drive module 11. The double-rack pushing module 3 resets the sprocket-type single-sided multi-point positioning module 5 to release the suspension channel steel. During this process, the Z-axis lifting drive module 11 drives the scraping plate 10 to move downward until the bottom edge of the scraping plate 10 contacts the upper surface of the suspension bracket 1. During the operation of the sprocket-type single-sided multi-point positioning module 5, the connecting-rod pushing structure 9 also synchronously receives the driving power from the double-rack pushing module 3 and the sprocket-type single-sided multi-point positioning module 5. Then, the scraping plate 10 moves in the Y-axis direction driven by the connecting-rod pushing structure 9. The two connecting-rod pushing structures 9 ensure that the two scraping plates 10 move together under synchronous control and can accurately scrape the waste chips on the surface of the suspension bracket 1, so that the waste chips are poured into the waste discharge port 2, thereby quickly clearing the waste chips and preventing the waste chips from staying or accumulating on the workpiece surface.

[0066] And when actually scraping and cleaning the waste chips above the suspension bracket 1, if the distance value detected by the distance sensor 12 is smaller initially, it means that the width value of the suspension channel steel at the top of the suspension bracket 1 is larger, and the range for subsequent scraping and cleaning of the waste chips is larger.

[0067] Therefore, when the distance value detected by the distance sensor 12 decreases, after the blanking of the suspension channel steel is completed, the controller first controls the second cylinder 1102 to start and the output end shrinks to the minimum value, then the scraping plate 10 moves downward synchronously to the minimum value, the bottom of the scraping plate 10 squeezes and contacts the top of the suspension bracket 1, the output end elongation distance of the electric telescopic rod 905 increases, then the connecting plate 903 rotates and drives the sliding plate 8 to move horizontally above the longitudinal beam 7 through the electric telescopic rod 905 and the fish-eye connecting rod 904 with an increased range, the sliding plate 8 drives the scraping plate 10 to increase the horizontal scraping range on the top of the suspension bracket 1. With the continuous reciprocating horizontal scraping of the scraping plate 10, the waste chips can effectively enter the discharge channel 101 along the waste discharge port 2 for recycling treatment, further ensuring the effective scraping effect on the waste chips at the top of the suspension bracket 1, with higher scraping quality and better cleaning effect, and effectively avoiding affecting the subsequent drilling of the suspended scrap steel.

[0068] After the waste chip cleaning is completed, the sprocket-type single-sided multi-point positioning module 5 and the scraping plate 10 return to the initial position under the control of the double-rack pushing module 3. After all components return to the initial state, the staff can easily place the next batch of workpieces to be processed on the suspension bracket 1 and continue the processing. During this process, the waste chips have been cleaned, the suspension bracket 1 remains clean, and the staff does not need additional cleaning work.
