Description

Technical Field

[0001] This invention relates to the field of high-speed rail cantilever support tube processing technology, and in particular to a processing and production device for high-speed rail cantilever support tubes. Background Technology

[0002] There are two main types of existing high-speed rail cantilever support tubes: square strips and round tubes. During processing, a long blank tube is typically drilled, chamfered, and cut to produce the finished support tube. However, when processing round tube support tubes, especially large-diameter ones requiring symmetrical drilling, the drill bit cannot penetrate the tube due to its large diameter. Therefore, it is necessary to manually rotate the round tube 180°. The method of manually rotating the cylindrical support tube has the following drawbacks: it increases the workload of workers, is time-consuming and labor-intensive, and reduces the efficiency of drilling holes in the cylindrical support tube; at the same time, human factors play a significant role in manually rotating the cylindrical support tube, resulting in rotations of less than 180° or greater than 180°, which leads to asymmetrical holes drilled in the cylindrical support tube and affects its quality. Therefore, a processing and production device for the support tube of high-speed rail cantilever arm is proposed to solve the above problems. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-10 The present invention provides a technical solution:

[0030] A processing and production device for high-speed rail cantilever support tubes includes a workbench 1 and a linear motor 2 mounted on the workbench 1 for moving a fixing mechanism, thereby realizing the movement of the high-speed rail cantilever support tube; the linear motor 2 is provided with a fixing mechanism acting on the support tube, which facilitates clamping and fixing the high-speed rail cantilever support tube, thus facilitating drilling of the high-speed rail cantilever support tube; a U-shaped frame 8 is fixedly connected to the workbench 1, an electric push rod 9 is mounted on the U-shaped frame 8, and a mounting plate 13 is fixedly connected to the telescopic end of the electric push rod 9; a drilling device 15 (existing technology) is mounted at the bottom of the mounting plate 13 for drilling holes in the high-speed rail cantilever support tube;

[0031] The fixing mechanism includes a movable plate 3 mounted on a linear motor 2, a clamping plate 2 7 fixed to one end of the movable plate 3, a strip-shaped opening on the movable plate 3, and a lead screw 19 rotatably mounted in the strip-shaped opening. One end of the lead screw 19 is fixedly connected to a handle. A clamping plate 4 is threaded onto the outer wall of the lead screw 19. Both the clamping plate 4 and the clamping plate 2 7 are rotatably mounted on a rotating plate 5 via a short shaft 32, and both are fixedly mounted on the inner side of a support platform 6. An adjustment mechanism acting on the rotating plate 5 is provided on the outer surface of the clamping plate 2 7. By using the adjustment mechanism, the rotation of the high-speed rail cantilever support tube can be realized, thereby facilitating symmetrical drilling in the high-speed rail cantilever support tube and improving the working efficiency of drilling the high-speed rail cantilever support tube.

[0032] A mounting bracket and a heat dissipation mechanism are fixed to the outer side of the clamp plate 2 7. The heat dissipation mechanism can blow air to the drilling site of the high-speed rail cantilever support pipe, so as to blow away the debris generated during drilling, which is beneficial to drilling the high-speed rail cantilever support pipe. At the same time, it can also remove the heat generated during drilling, so as to cool down the drill bit in the drilling equipment 15 and improve the service life of the drill bit.

[0033] In this invention, the adjustment mechanism includes a gear 24 disposed at the outer end of the short shaft 32, a connecting shaft 23 rotatably disposed on the clamping plate 7, and a quarter gear 29 rotatably disposed on the outer wall of the connecting shaft 23 and cooperating with the gear 24. Through the mutual cooperation of the quarter gear 29 and the gear 24, the intermittent rotation of the rotating plate 5 is achieved, that is, the rotating plate 5 can rotate 180° each time, thereby achieving the rotation of the high-speed rail cantilever support tube after rotating 180° and then stopping the rotation; the quarter gear 29 has an annular cavity 38, and the annular cavity 38 is provided with a mechanism that acts on the quarter gear. The adjusting component of 29 has a fixing component on the clamping plate 7 that acts on the rotating plate 5. The fixing component facilitates the fixing of the rotating plate 5, thereby fixing the high-speed rail cantilever support tube and preventing it from rotating when drilling the high-speed rail cantilever support tube, which is beneficial for drilling the high-speed rail cantilever support tube. One end of the connecting shaft 23 has a driving mechanism that acts on the heat dissipation mechanism. The driving mechanism facilitates the synchronous operation of the heat dissipation mechanism and the adjusting mechanism, thereby achieving cooling of the high-speed rail cantilever support tube during drilling and rotation of the high-speed rail cantilever support tube.

[0034] In this invention, the fixing components include an L-shaped limiting plate 18 disposed on the clamping plate 2 7, an L-shaped plate 17 slidably disposed on the L-shaped limiting plate 18, and a compression spring 21 disposed between the L-shaped plate 17 and the L-shaped limiting plate 18. A fixing rod 33 and a sliding rod 34 are fixedly connected to the L-shaped plate 17. Fixing holes that cooperate with the fixing rod 33 are provided on both the rotating plate 5 and the clamping plate 2 7. An unlocking component 35 that cooperates with the sliding rod 34 is provided on the quarter gear 29. By using the unlocking component 35, the rotating plate 5 can be automatically unlocked and fixed when the rotation of the rotating plate 5 is adjusted, thereby fixing the high-speed rail cantilever support tube.

[0035] In this invention, the unlocking component 35 includes a fixing groove 3501 formed on the quarter gear 29, an unlocking groove 3502 formed at one end of the fixing groove 3501, and a stabilizing groove 3503 formed at one end of the unlocking groove 3502. The stabilizing groove 3503 and the fixing groove 3501 are connected by a return groove 3504. When the sliding rod 34 is located in the fixing groove 3501, the fixing rod 33 is inserted into the fixing hole to fix the rotating plate 5. When the sliding rod 34 slides in the unlocking groove 3502, the fixing rod 33 moves outward. When the slide rod 34 moves to the stabilizing groove 3503, the fixing rod 33 separates from the fixing hole and the quarter gear 29 and the gear 24 are about to mesh, thus unlocking the rotating plate 5. When the slide rod 34 slides in the stabilizing groove 3503, the quarter gear 29 and the gear 24 mesh. When the slide rod 34 is about to separate from the stabilizing groove 3503, the fixing rod 33 quickly inserts into the fixing hole to fix the rotating plate 5. Then the slide rod 34 enters the return groove 3504 and moves into the fixing groove 3501.

[0036] In this invention, the adjusting component includes a ratchet 37 fixed to the outer wall of the connecting shaft 23 within the annular cavity 38. A pawl 36, which rotatably engages with the ratchet 37, is provided within the annular cavity 38 via a torsion spring shaft. The torsion spring shaft consists of a torsion spring and a shaft, and exerts an automatic restoring force on the ratchet 36. Through the mutual engagement of the ratchet 37 and the pawl 36, the connecting shaft 23 can drive the quarter gear 29 to rotate when it rotates counterclockwise, while the quarter gear 29 idles when the connecting shaft 23 rotates clockwise, thus preventing the rotating plate 5 from rotating and ensuring the continuous operation of the heat dissipation mechanism.

[0037] In this invention, the driving mechanism includes a second connecting plate 28 fixed to the outer end of the connecting shaft 23, a rotating shaft 27 fixed to the second connecting plate 28, and a first connecting plate 22 fixed to one end of the rotating shaft 27. A drive motor 16 is mounted on the first connecting plate 22 via a short shaft 2, and the drive motor 16 is a forward and reverse rotating motor, which can realize the forward and reverse rotation of the output shaft; and the drive motor 16 is mounted on the mounting bracket via a motor bracket.

[0038] In this invention, the heat dissipation mechanism includes a sealing box 11 mounted on a mounting frame, a sealing plate 25 slidably mounted inside the sealing box 11, and a connecting rod 26 rotatably mounted on the sealing plate 25. One end of the connecting rod 26 is rotatably mounted with a rotating shaft 27. An annular air chamber 20 is provided inside the mounting plate 13. Multiple air outlet pipes 14 are evenly inclined at the bottom of the annular air chamber 20. The sealing box 11 and the annular air chamber 20 are connected by an air guide pipe 10. A one-way air outlet valve 12 is provided on the air guide pipe 10. An air inlet pipe 30 is provided on the sealing box 11. A one-way air inlet valve 31 is provided on the air inlet pipe 30.

[0039] Working principle: In use, the high-speed rail cantilever support tube is first placed between clamping plate 4 and clamping plate 7. Then, the handle is turned to drive the lead screw 19 to rotate, which in turn drives clamping plate 7 to move, thereby clamping and fixing the high-speed rail cantilever support tube with the two rotating plates 5. Then, the linear motor 2 is driven, which drives the movable plate 3 to move, thereby moving the high-speed rail cantilever support tube so that the position where the high-speed rail cantilever support tube needs to be drilled is moved below the drill bit of the drilling device 15. Finally, the drilling device 15 and the electric push rod 9 are opened. The movable end of the electric push rod 9 moves downward, which drives the drilling device 15 to move downward. Finally, the drilling device 15 is opened to drill a hole in the high-speed rail cantilever support tube.

[0040] When drilling the support tube of the high-speed rail cantilever, the drive motor 16 is started, and the output shaft of the drive motor 16 rotates clockwise. The clockwise rotation of the output shaft of the drive motor 16 drives the short shaft 2, the connecting plate 22, the rotating shaft 27 and the connecting plate 28 to rotate, which in turn drives the connecting shaft 23 to rotate, thereby driving the connecting rod 26 and the sealing plate 25 to move back and forth. When the sealing plate 25 moves closer to the drive motor 16, outside air enters the sealing box 11 through the air inlet pipe 30. When the sealing plate 25 moves away from the drive motor 16, the gas in the sealing box 11 is transported to the annular air chamber 20 through the air guide pipe 10. Finally, the gas is blown into the drill bit of the drilling equipment 15 through the air outlet pipe 14, thereby cooling the drill bit in the drilling equipment 15 and improving the service life of the drill bit in the drilling equipment 15.

[0041] When the output shaft of the drive motor 16 rotates clockwise, the ratchet 37 and pawl 36 work together, and the connecting shaft 23 will not drive the quarter gear 29 when it rotates.

[0042] Meanwhile, after one end of the high-speed rail cantilever support tube is drilled, the linear motor 2 is controlled to move the other end of the high-speed rail cantilever support tube to below the drilling equipment 15, and then the drilling equipment 15 drills a hole in the high-speed rail cantilever support tube.

[0043] After all the holes on the upper part of the high-speed rail cantilever support tube are drilled, the drive motor 16 is controlled to rotate its output shaft counterclockwise. At this time, with the cooperation of pawls 37 and 36, the connecting shaft 23 rotates, driving the quarter gear 29 to rotate, thereby driving the unlocking component 35 to rotate. When the slide rod 34 slides in the fixing groove 3501, the fixing rod 33 inserts into the fixing hole of the rotating plate 5, fixing the rotating plate 5. When the slide rod 34 slides in the unlocking groove 3502, the fixing rod 33 slowly moves outward. When the slide rod 34 moves into the stabilizing groove 3503, the fixing rod 33 separates from the fixing hole. Simultaneously, the four... The teeth of the quarter gear 29 mesh with the gear 24. As the slide rod 34 slides in the stabilizing groove 3503, the quarter gear 29 drives the gear 24 to rotate, which in turn drives the short shaft 32 to rotate, thereby driving the rotating plate 5 to rotate, thus realizing the rotation of the high-speed rail cantilever support tube. When the slide rod 34 moves from the stabilizing groove 3503 to the return groove 3504, the quarter gear 29 separates from the gear 24. The gear 24 will not rotate, while the high-speed rail cantilever support tube rotates 180°, realizing symmetrical drilling on the high-speed rail cantilever support tube. At the same time, under the action of the compression spring 21, the fixing rod 33 quickly inserts into the fixing hole of the rotating plate 5 to fix the rotating plate 5.

[0044] Then, the output shaft of the drive motor 16 is rotated clockwise, and the drilling equipment 15 is used to drill holes in the high-speed rail cantilever support tube. After the high-speed rail cantilever support tube is drilled, the handle is turned to reset the clamp 4, thereby unlocking the high-speed rail cantilever support tube and facilitating the unloading of the high-speed rail cantilever support tube.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
