Description

Technical Field

[0001] This invention belongs to the field of railway freight car maintenance technology, and more specifically, relates to a double-layer plate cutting device. Background Technology

[0002] Railway freight cars primarily transport goods and can be categorized into general-purpose freight cars and special-purpose freight cars based on their intended use. General-purpose freight cars are vehicles suitable for transporting a variety of goods, such as open wagons, boxcars, and flatcars. Special-purpose freight cars are vehicles used for transporting a specific type of goods, such as coal cars, container cars, and bulk cement cars.

[0003] After a period of operation, railway freight cars require maintenance on the double-layered panels of components such as side walls, end walls, top walls, and lower side doors of open wagons. This involves cutting and disassembling the rusted parts of the double-layered panels and then welding new double-layered panels onto the cut areas. However, if no protective measures are taken during the cutting and disassembly process, the cut parts can easily fall and injure workers, seriously threatening their personal safety. Summary of the Invention

[0006] In one possible implementation, the clamping member includes a mating plate rotatably connected to the through cavity and a clamping plate connected to the mating plate on the side away from the mounting seat. The mating plate and the clamping plate are set at an angle to form a receiving cavity for accommodating the double-layer plate. The lifting member can drive the support plate to move upward so that the double-layer plate presses down on the mating plate and causes the clamping plate to swing vertically to press against the top surface of the double-layer plate.

[0007] In some embodiments, the clamping member is rotatably connected to the through cavity via a rotating shaft. A torsion spring is sleeved on the rotating shaft to rotate the mating plate to protrude from the top surface of the support plate. One end of the torsion spring is connected to the inner wall of the through cavity, and the other end is connected to the clamping member.

[0008] In some embodiments, a limiting member is provided above the support plate to abut against the outer wall of the clamping plate to limit the swing amplitude of the clamping member. The limiting member is located on the side of the clamping member away from the mounting base.

[0009] In one possible implementation, the translation component is a slider, and a lead screw threadedly connected to the slider is provided through the slider in the horizontal direction. The lead screw is rotatably connected to the mounting base, and one end of the lead screw is connected to a rotary drive component.

[0010] In some embodiments, the cutting element is hinged to the slider via a hinge rod, and a second telescopic member for driving the hinge rod is hinged to the slider. The telescopic end of the second telescopic member is hinged to the hinge rod and is used to drive the cutting element to swing vertically to move closer to or away from the double-layer plate.

[0011] In some embodiments, the hinge rod and the cutting element are rotatably connected by a pin, and a nut is threaded onto the pin.

[0012] In one possible implementation, a positioning block is slidably connected to the bottom of the mounting base in a horizontal direction, and the adsorption element is disposed downward through the positioning block. The adsorption element is threadedly connected to the positioning block, and the inner end of the adsorption element is used to abut against the bottom surface of the mounting base to lock the horizontal position of the adsorption element.

[0013] In one possible implementation, the bracket is provided with a horizontally extending third telescopic member, the telescopic end of which is connected to a horizontally extending slide bar, the slide bar being arranged perpendicular to the main axis of the third telescopic member, and a lifting member being connected to the bottom of the slide bar.

[0014] When cutting double-layer boards using a double-layer board cutting device, the following steps are included:

[0015] The double-layer plate is adsorbed by an adsorption component, so that the cutter and the weld seam of the double-layer plate are aligned vertically, and the distance between the cutting head of the cutter and the weld seam is 3mm-5mm. The spindle of the cutter and the surface of the double-layer plate form an angle of 50°-70°.

[0016] The lifting device moves the support plate up to abut against the bottom surface of the double-layer plate, while the clamping device swings vertically and presses against the top of the double-layer plate.

[0017] Activate the cutting component and use the translation component to move the cutting component to cut the double-layer plate.

[0018] This application provides a double-layer board cutting device. In actual use, a gap is first cut into the rusted part of the double-layer board to allow the support plate to pass through. Then, the adsorption component is aligned and adsorbed onto the double-layer board to be cut, so that the cutting component is aligned with the part of the double-layer board to be cut. Through the sliding connection between the lifting component and the bracket, and the adjustment of the position of the support plate driven by the lifting component itself, the support plate is positioned on the side of the double-layer board away from the mounting seat and in contact with the double-layer board. The clamping component swings down and presses the double-layer board onto the support plate, and with the push of the first telescopic component, the clamping component can press the part of the double-layer board to be cut onto the support plate. Finally, the translation component drives the cutting component to cut the double-layer board, avoiding the direct fall of the cut part of the double-layer board and ensuring the personal safety of the workers.

[0019] The double-layer board cutting device provided by this invention, compared with the prior art, adjusts the horizontal position of the lifting component on the support and causes the lifting component to drive the support plate to rise and fall, so that the support plate is located on the side of the double-layer board away from the mounting seat and in contact with the double-layer board. The clamping component swings down and presses the double-layer board onto the support plate, and with the push of the first telescopic component against the clamping component, the clamping component can press the double-layer board onto the support plate. Finally, the translation component drives the cutting component to cut the double-layer board, avoiding the direct fall of the cut part of the double-layer board and ensuring the personal safety of the workers.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0032] Please see Figures 1 to 7The double-layer board cutting device provided by the present invention will now be described. The double-layer board cutting device includes a mounting base 10, an adsorption member 91, a translation member 20, a cutting member 30, a lifting member 40, and a clamping member 60. A bracket 11 is provided on the top of the mounting base 10; the adsorption member 91 is disposed at the bottom of the mounting base 10 for adsorbing the double-layer board 1; the translation member 20 is slidably connected to the top surface of the mounting base 10 in a horizontal direction; the cutting member 30 is disposed on the translation member 20 for cutting the double-layer board 1; the lifting member 40 is slidably connected to the bracket 11, and the sliding direction of the lifting member 40 is perpendicular to the sliding direction of the translation member 20. The lifting member 40 extends to the bottom of the mounting base 10 and is connected to a support plate 50 for supporting the double-layer plate 1. The top surface of the support plate 50 and the bottom surface of the mounting base 10 form an accommodating space for accommodating the double-layer plate 1. A through cavity 51 is provided through the support plate 50. The pressing member 60 is rotatably connected to the through cavity 51. The pressing member 60 can swing vertically and press down on the top surface of the double-layer plate 1. The support plate 50 is provided with a first telescopic member 70 for pushing the pressing member 60 to make the pressing member 60 swing.

[0033] This application provides a double-layer plate cutting device. Taking a double-layer plate 1 located on the top of a railway freight car as an example, in its actual use, a gap is first cut out of the rusted part of the double-layer plate 1 to allow the support plate 50 to pass through. Then, the adsorption member 91 is aligned and adsorbed onto the double-layer plate 1 to be cut, so that the cutting member 30 is aligned with the part of the double-layer plate 1 to be cut. By adjusting the horizontal position of the lifting member 40 on the bracket 11, the lifting member 40 drives the support plate 50 to rise and fall, so that the support plate 50 is located on the side of the double-layer plate 1 away from the mounting base 10 and in contact with the double-layer plate 1. The clamping member 60 swings down and presses the double-layer plate 1 onto the support plate 50, and with the push of the first telescopic member 70 against the clamping member 60, the clamping member 60 can press the double-layer plate 1 onto the support plate 50. Finally, the translation member 20 drives the cutting member 30 to cut the double-layer plate 1, avoiding the direct fall of the cut part of the double-layer plate 1 and ensuring the personal safety of the workers.

[0034] It should be noted that the above-mentioned double-layer plate cutting device has multiple usage states and can be used for cutting double-layer plates 1 of components such as side walls, end walls, top walls of railway freight cars and lower side doors of open wagons.

[0035] Compared with the prior art, the double-layer plate cutting device provided by the present invention adjusts the horizontal position of the lifting member 40 on the bracket 11 and causes the lifting member 40 to drive the support plate 50 to rise and fall, so that the support plate 50 is located on the side of the double-layer plate 1 away from the mounting seat 10 and contacts and cooperates with the double-layer plate 1. The pressing member 60 swings down and presses the double-layer plate 1 onto the support plate 50, and cooperates with the first telescopic member 70 to push the pressing member 60, so that the pressing member 60 can press the double-layer plate 1 onto the support plate 50. Finally, the translation member 20 drives the cutting member 30 to cut the double-layer plate 1, avoiding the direct fall of the cut part of the double-layer plate 1 and ensuring the personal safety of the workers.

[0036] In one possible implementation, the aforementioned clamping member 60 adopts, as shown in... Figures 1 to 5 The structure shown is described in the following document. Figures 1 to 5 The clamping member 60 includes a mating plate 61 rotatably connected to the through cavity 51 and a clamping plate 62 connected to the mating plate 61 on the side away from the mounting base 10. The mating plate 61 and the clamping plate 62 are set at an angle to form a receiving cavity 63 for accommodating the double-layer plate 1. The lifting member 40 can drive the support plate 50 to move upward so that the double-layer plate 1 presses down on the mating plate 61 and causes the clamping plate 62 to swing vertically to press against the top surface of the double-layer plate 1.

[0037] Specifically, the first telescopic member 70 is used to push the pressing plate 62. Through the sliding connection between the lifting member 40 and the bracket 11, and the adjustment of the position of the support plate 50 driven by the lifting member 40 itself, the support plate 50 is positioned on the side of the double-layer plate 1 away from the mounting base 10. At this time, the position of the support plate 50 is adjusted so that the mating plate 61 and the edge of the double-layer plate 1 are aligned. The lifting member 40 is controlled to drive the support plate 50 to gradually approach the double-layer plate 1. The double-layer plate 1 gradually squeezes the mating plate 61, causing the pressing plate 62 to swing down and press the double-layer plate 1 onto the support plate 50. With the push of the first telescopic member 70 against the pressing plate 62, the pressing plate 62 can press the cut part of the double-layer plate 1 onto the support plate 50.

[0038] Furthermore, the first telescopic member 70 is located on the side of the through cavity 51 away from the double-layer plate 1, and the telescopic end of the first telescopic member 70 is provided with an outwardly arc-shaped pushing block. The arc-shaped pushing block can facilitate a slight sliding fit between the first telescopic member 70 and the outer wall of the pressing plate 62 when the first telescopic member 70 pushes the pressing plate 62, thereby improving the pressing effect of the pressing plate 62 on the double-layer plate 1.

[0039] In some embodiments, see Figures 1 to 5 The clamping member 60 is rotatably connected to the through cavity 51 via a rotating shaft 65. A torsion spring 64 is sleeved on the rotating shaft 65 to rotate the mating plate 61 to protrude from the top surface of the support plate 50. One end of the torsion spring 64 is connected to the inner wall of the through cavity 51, and the other end is connected to the clamping member 60.

[0040] Specifically, in its natural state, the torsion spring 64 allows the outer edge of the mating plate 61 to protrude beyond the top surface of the support plate 50, facilitating the compression of the mating plate 61 by the double-layer plate 1. The torsion spring 64 also allows the clamping member 60 to return to its initial state after the double-layer plate 1 has been cut and the cut portion removed, facilitating future use and avoiding repeated manual adjustments.

[0041] In some embodiments, see Figures 1 to 4 Above the support plate 50 is a limiting member 52 for abutting against the outer wall of the clamping plate 62 to limit the swing amplitude of the clamping member 60. The limiting member 52 is located on the side of the clamping member 60 away from the mounting base 10.

[0042] Specifically, the limiting member 52 is in the shape of a door frame. After the cut portion of the double-layer plate 1 is removed from the support plate 50, the clamping member 60 returns to its initial state under the action of the torsion spring 64. After the outer edge of the mating plate 61 protrudes to a certain extent from the side of the support plate 50 near the lifting member 40, the clamping plate 62 abuts against the limiting member 52, thereby ensuring that the initial state of the clamping member 60 is the optimal state and improving practicality.

[0043] Furthermore, the outer edge of the mating plate 61 has an arc-shaped transition portion that curves outward. This facilitates the compression of the mating plate 61 by the double-layer plate 1.

[0044] Furthermore, the clamping plate 62 has an arc-shaped protrusion clamping part on the side near the mating plate 61, and the clamping part is located near the outer edge of the clamping plate 62.

[0045] In one possible implementation, the aforementioned translation component 20 adopts, as shown in... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The translation component 20 is a slider, and a lead screw 21 threadedly connected to the slider is provided along the horizontal direction. The lead screw 21 is rotatably connected to the mounting base 10, and one end of the lead screw 21 is connected to a rotary drive component 22.

[0046] Specifically, when it is necessary to cut the double-layer plate 1, the rotary drive 22 drives the lead screw 21 to rotate, and the slider drives the cutting component 30 to move on the mounting base 10, thereby cutting the double-layer plate 1 and facilitating the cutting of the double-layer plate 1.

[0047] In some embodiments, see Figures 1 to 3 The cutting piece 30 is hinged to the slider via a hinge rod 81. A second telescopic member 80 for driving the hinge rod 81 is hinged to the slider. The telescopic end of the second telescopic member 80 is hinged to the hinge rod 81 and is used to drive the cutting piece 30 to swing vertically to approach or move away from the double-layer plate 1.

[0048] Specifically, the hinge rod 81 is hinged to the translation member 20, and one end of the second telescopic member 80 is hinged to the translation member 20 and the other end is hinged to the hinge rod 81. This is used to drive the hinge rod 81 to swing, thereby adjusting the distance between the cutting member 30 and the double-layer plate 1 and improving the cutting effect of the double-layer plate 1.

[0049] In some embodiments, see Figures 1 to 3 The hinge rod 81 and the cutting part 30 are rotatably connected by a pin 82, and a nut 83 is threaded onto the pin 82.

[0050] Specifically, after the second telescopic member 80 drives the cutting member 30 to swing to a suitable position, the nut 83 can be loosened, and then the cutting member 30 can be rotated to further adjust the tilt angle of the cutting member 30 so that the cutting end of the cutting member 30 is aligned with the suitable position of the double-layer plate 1. Finally, the nut 83 is tightened, which improves the convenience and practicality of adjusting the cutting member 30.

[0051] In one possible implementation, the aforementioned mounting base 10 adopts the following... Figure 6 The structure shown is described in the following document. Figure 6 The bottom of the mounting base 10 is slidably connected to a positioning block 90 in the horizontal direction. The adsorption member 91 is set downward through the positioning block 90. ​​The adsorption member 91 is threadedly connected to the positioning block 90. ​​The inner end of the adsorption member 91 is used to abut against the bottom surface of the mounting base 10 to lock the horizontal position of the adsorption member 91.

[0052] Specifically, the positioning blocks 90 are slidably connected to the mounting base 10 along its extension direction. Several positioning blocks 90 are spaced apart along a direction perpendicular to the extension direction of the mounting base 10. When the surface of the double-layer plate 1 is uneven, the spacing between the positioning blocks 90 can be adjusted to avoid uneven areas, ensuring that the mounting base 10 is parallel to the double-layer plate 1 and guaranteeing the cutting effect of the cutting component 30.

[0053] After adjusting the position of the positioning block 90, rotate the adsorption component 91 so that the inner end of the adsorption component 91 presses against the bottom surface of the mounting base 10, thereby locking the position of the positioning block 90. ​​Finally, the adsorption component 91 is adsorbed onto the double-layer plate 1, which improves practicality.

[0054] Furthermore, the adsorption element 91 includes a locking post threadedly connected to the positioning block 90 and a magnet connected to the outer end of the locking post.

[0055] In one possible implementation, the aforementioned support 11 adopts the following... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2The bracket 11 is provided with a horizontally extending third telescopic member 42. The telescopic end of the third telescopic member 42 is connected to a horizontally extending slide bar 41. The slide bar 41 is set perpendicular to the main shaft of the third telescopic member 42. The lifting member 40 is connected to the bottom of the slide bar 41.

[0056] Specifically, the third telescopic member 42 is used to drive the slide bar 41 to move in a direction parallel to the plate surface of the mounting base 10, that is, to adjust the distance between the lifting member 40 and the double-layer plate 1. The lifting member 40 drives the support plate 50 to move, which is used to adjust the distance between the plate surface of the support plate 50 and the plate surface of the double-layer plate 1.

[0057] Furthermore, two lifting components 40 are provided at intervals along the extension direction of the slide bar 41, which improves the stability of the lifting component 40 driving the support plate 50 to move.

[0058] The present invention also provides a cutting method for cutting a double-layer plate 1 using a double-layer plate cutting device, comprising the following steps:

[0059] The double-layer plate 1 is adsorbed by the adsorption component 91, so that the cutting component 30 and the weld seam 2 of the double-layer plate 1 are aligned vertically, and the distance between the cutting head of the cutting component 30 and the weld seam 2 is 3mm-5mm. The main shaft of the cutting component 30 and the plate surface of the double-layer plate 1 form an angle of 50°-70°.

[0060] The lifting component 40 is used to move the support plate 50 upward and abut against the bottom surface of the double-layer plate 1, while the pressing component 60 swings vertically and presses against the top of the double-layer plate 1.

[0061] Open the cutting component 30 and make the translation component 20 move the cutting component 30 to cut the double-layer plate 1.

[0062] Specifically, because the arc is easily broken and continuous cutting is not possible when cutting the rust-filled middle of the double-layer plate 1, in order to avoid reducing the cutting quality, it is necessary to cut the weld seam 2 of the double-layer plate 1 during cutting to ensure the complete cutting of the double-layer plate 1 and improve the cutting quality and efficiency.

[0063] The specific process is as follows: First, a gap is cut into the rusted part of the double-layer plate 1 to allow the support plate 50 to pass through. Then, the adsorption component 91 is aligned and adsorbed onto the double-layer plate 1 to be cut. The extension and retraction of the second telescopic component 80 is controlled to align the cutting component 30 with the part of the double-layer plate 1 to be cut. The angle of the cutting component 30 is further adjusted by loosening the nut 83, so that the distance between the cutting component 30 and the weld 2 is 3mm-5mm, and the acute angle between the cutting component 30 and the double-layer plate 1 is α=50°-70° (e.g., ...). Figure 7As shown, the sliding connection between the lifting component 40 and the bracket 11 is adjusted, and the position of the support plate 50 driven by the lifting component 40 itself is adjusted so that the support plate 50 is located on the side of the double-layer plate 1 away from the mounting base 10. At this time, the position of the support plate 50 is adjusted so that the edge of the mating plate 61 is aligned with the edge of the double-layer plate 1. The lifting component 40 is controlled to drive the support plate 50 to gradually approach the double-layer plate 1. The double-layer plate 1 gradually squeezes the mating plate 61, so that the pressing plate 62 swings down and presses the double-layer plate 1 onto the support plate 50. With the cooperation of the first telescopic component 70 pushing the pressing plate 62, the pressing plate 62 can press the cut part of the double-layer plate 1 onto the support plate 50.

[0064] In this process, after the cutting of part 30 begins, the cutting line penetrates the weld 2 and the base material, and then penetrates the second layer of plate. Once penetration is observed, the cutting line moves at a constant speed of 300mm-800mm / s to complete the cutting. The cutting current and cutting speed are adjusted according to different plate thicknesses. After disassembling and separating the steel plates, the scrapped steel plates are removed, and the remaining steel sections are reused and re-welded with new steel plates to meet the standards for the repair of railway freight cars. This reduces costs, avoids secondary trimming and cutting, minimizes cutting deformation, and facilitates the assembly welding of the next process, thereby improving assembly welding efficiency. Furthermore, the bevel formed after cutting facilitates the splicing and welding of new steel plates, eliminating the need for secondary beveling, reducing costs, and ensuring welding quality.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
