Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly relates to a butt welding device for cable protection pipes. Background Art

[0002] A cable protection pipe refers to a metal protection pipe with a certain mechanical strength that is laid on the outer layer of a cable to prevent the cable from being damaged. Cable protection pipes are mainly installed in sections where communication cables cross power lines to prevent power lines from breaking and causing short-circuit accidents, which may cause communication cables and wire ropes to become charged, so as to protect the cables, switches, and circuit boards, avoid burning out the entire machine, and also play a certain role in isolating the magnetic field interference of power lines. Therefore, cable protection pipes need to be connected by welding to form a firm connection between them, which is not easy to loosen or break, ensuring the safe operation of the cables.

[0003] Deficiencies in the prior art: Before welding, two cable protection pipes need to be butted together. However, the butted joints of existing cable protection pipes may have burrs or unevenness due to cutting, which easily causes gaps between the two cable protection pipes, affecting the welding effect. At the same time, since the welding of cable protection pipes requires circumferential welding, the existing welding operations usually fix the cable protection pipes and then weld. After welding a part, the welding position is adjusted and fixed again for welding, which greatly reduces the welding efficiency of the device and easily causes deviation in the welding position, affecting the welding quality. Summary of the Invention

[0004] The problem to be solved by the present invention is that existing cable protection pipes may have burrs or unevenness due to cutting, resulting in gaps between the butted joints of the two cable protection pipes, affecting the welding effect.

[0015] The technical effects and advantages of the present invention:

[0016] 1. The present invention supports two cable protection pipes to be welded by providing two docking platforms, and fixes the protection pipes on the top of the fixed seat through a fixing component to ensure the stability during the welding process of the protection pipes, facilitating the docking of the welding joints between the two cable protection pipes. Place the two cable protection pipes on the tops of the fixed seats on both sides respectively, start the ejector rod, and drive the second clamping block to move up and down through the telescoping of the extending end of the ejector rod, so that the second clamping block clamps and fixes the cable protection pipe on the top of the first clamping block.

Detailed implementation manners

[0026] The present invention provides a cable protection pipe butt welding device, as Figure 1 - Figure 6 shown, which includes a welding table 1. Two sliding grooves 2 are opened at the top end of the welding table 1. Two docking tables 3 are arranged at the top end of the welding table 1. Two fixed seats 4 are fixedly installed at the top end of the docking table 3. A fixing component 5 for fixing the cable protection pipe is arranged between the two fixed seats 4. A grinding component 6 for grinding the cable protection pipe is arranged in the middle of the welding table 1.

[0027] Further, as Figure 1 , Figure 3 and Figure 4 shown, the fixing component 5 includes two support frames 51 fixedly connected to the top end of the docking table 3. An annular rack 52 is rotatably connected between the two support frames 51. A clamping component 53 for fixing the cable protection pipe is arranged on the inner wall of the annular rack 52. Annular guide rails 54 are fixedly connected to both sides of the outer surface of the annular rack 52.

[0028] Further, as Figure 2 and Figure 4 shown, an annular groove is opened at one end of the support frame 51 close to the annular rack 52. The inner cavity of the annular groove is movably connected to the annular guide rail 54.

[0029] Further, as Figure 3 and Figure 5 shown, the clamping component 53 includes a first fixing block 531 fixedly connected to the bottom end of the inner wall of the annular rack 52. A second fixing block 532 is fixedly connected to the top end of the inner cavity of the annular rack 52. A first clamping block 533 is fixedly connected to the top end of the first fixing block 531. A second clamping block 534 is movably connected to the bottom end of the second fixing block 532.

[0030] Furthermore, as Figure 2 and Figure 5 shown, the connection between the tops of the two fixed seats 4 and the inner cavity of the annular rack 52 is communicated, and the tops of the fixed seats 4 and the tops of the first clamping blocks 533 are on the same horizontal line.

[0031] Furthermore, as Figure 5 shown, ejector rods 535 are fixedly installed on both sides of the top of the first fixed block 531. The extending ends of the two ejector rods 535 are respectively fixedly connected to both sides of the bottom of the second clamping block 534. Telescopic connecting rods 536 are fixedly connected to both sides of the top of the second clamping block 534. The tops of the telescopic connecting rods 536 penetrate through the second fixed block 532 and are fixedly connected to the inner wall of the annular rack 52. When welding is required, the cable protection pipe is fixed in the inner cavity of the annular rack 52 through the clamping assembly 53. First, the two cable protection pipes to be welded are directly placed on the tops of the fixed seats 4 on both sides. Then, the ejector rods 535 are started. Through the expansion and contraction of the extending ends of the ejector rods 535, the second clamping block 534 is driven to move up and down. During the up and down movement of the second clamping block 534, the telescopic connecting rods 536 also expand and contract as they move, ensuring the stability of the second clamping block 534, so that the second clamping block 534 clamps and fixes the cable protection pipe on the top of the first clamping block 533. At the same time, according to the specific specifications and dimensions of the cable protection pipe, the position of the second clamping block 534 can be controlled, so that the clamping assembly 53 can fix cable protection pipes of various different specifications and dimensions. Since the tops of the fixed seats 4 and the tops of the first clamping blocks 533 are on the same horizontal line, the accuracy of the butt-joint position between the two cable protection pipes is ensured through the fixed seats 4 and the clamping assembly 53.

[0032] Furthermore, as Figure 3 shown, a rotary motor 55 is fixedly installed on one side of the top of the docking platform 3. The output end of the rotary motor 55 is fixedly connected to a gear 56. The outer surface of the gear 56 is meshed with the outer surface of the annular rack 52. After the clamping assembly 53 fixes the cable protection pipe, the welding operation is carried out. When the cable protection pipe needs to be rotated during the welding process, the rotary motor 55 is started. The gear 56 is driven to rotate by the rotary motor 55. When the gear 56 rotates, the annular rack 52 meshed on its surface rotates, so that the annular rack 52 rotates in the inner cavity of the annular groove on the support frame 51 through the annular guide rails 54 on both sides of its outer surface, driving the cable protection pipe fixed in the clamping assembly 53 to rotate during the welding process as the welding position changes, so that the device can directly carry out circular welding on the cable protection pipe, without the need to adjust the position after welding a part, re-fix and then weld again, avoiding multiple adjustments of the position, resulting in deviation of the welding position and affecting the welding quality of the device. At the same time, it avoids the rupture of the welded part during the adjustment process, effectively improving the welding efficiency of the device.

[0033] Furthermore, as Figure 6As shown in the figure, the grinding assembly 6 includes a linear guide rail 61 fixedly installed in the middle of the welding table 1. A slider 62 is provided at the top end of the linear guide rail 61. A double-output shaft motor 63 is fixedly installed at the top end of the slider 62. Grinding discs 64 are fixedly connected to both output ends of the double-output shaft motor 63. A driving device 65 for driving the slider 62 to move is provided in the middle of the top end of the welding table 1.

[0034] Further, as Figure 1 and Figure 2 shown in the figure, hydraulic cylinders 7 are fixedly installed on both sides of the top end of the welding table 1. The output end of the hydraulic cylinder 7 is fixedly connected to one end of the docking table 3. The bottom end of the docking table 3 is movably connected to the inner cavity of the chute 2. After the cable protection pipes to be welded on both sides are fixed, the driving device 65 is started. The driving device 65 drives the slider 62 to slide on the linear guide rail 61. The grinding assembly 6 is moved between the two fixing assemblies 5 through the movement of the slider 62. Then the hydraulic cylinder 7 is started. The extended end of the hydraulic cylinder 7 pushes the docking table 3 to slide in the inner cavity of the chute 2, so that the cable protection pipes fixed on both sides are moved to the positions of the two grinding discs 64. The double-output shaft motor 63 is started. The two output ends of the double-output shaft motor 63 drive the grinding discs 64 on both sides to rotate, and the welding joints of the cable protection pipes on both sides are ground at the same time, ensuring the flatness of the welding joints of the cable protection pipes, effectively avoiding the generation of gaps when the two cable protection pipes are docked, and ensuring the welding effect of the device.

[0035] Further, as Figure 1 and Figure 2 shown in the figure, an equipment rack 8 is fixedly installed in the middle of the welding table 1. A welding device 9 for welding is provided in the middle of the top end of the equipment rack 8. The welding device 9 is located above the grinding assembly 6. The two cable protection pipes after being processed are welded by the welding device 9.

[0036] Working principle of the present invention: First, directly place the two cable protection pipes to be welded on the top ends of the fixed seats 4 on both sides. Each cable protection pipe is supported by two fixed seats 4 and simultaneously penetrates through the fixing component 5. The fixing component 5 is used to fix the cable protection pipe. When fixing, first start the ejector rod 535. The extending end of the ejector rod 535 extends, pushing the second clamping block 534 downward. During the movement of the second clamping block 534, the telescopic connecting rod 536 also expands and contracts as it moves to ensure the stability of the second clamping block 534. Through the pushing of the extending end of the ejector rod 535, the second clamping block 534 clamps and fixes the cable protection pipe on the top end of the first clamping block 533, enabling the clamping component 53 to control the position of the second clamping block 534 according to the specific specifications and dimensions of the cable protection pipe, effectively improving the applicability of the device. After the fixing is completed, first start the driving device 65. The driving device 65 drives the slider 62 to slide on the linear guide rail 61. Through the movement of the slider 62, the grinding component 6 is moved between the two fixing components 5. Then start the hydraulic cylinder 7. The extending end of the hydraulic cylinder 7 extends, pushing the docking platform 3 to slide inside the chute 2, causing the cable protection pipes fixed on both sides to move to the positions of the two grinding discs 64. Start the double-output shaft motor 63. The two output ends of the double-output shaft motor 63 drive the grinding discs 64 on both sides to rotate, simultaneously grinding the welding joints of the cable protection pipes on both sides to ensure the flatness of the welding joints of the cable protection pipes, effectively avoiding the generation of gaps when the two cable protection pipes are docked. After the grinding is completed, start the driving device 65 again. The driving device 65 drives the slider 62 to move the grinding component 6 to the side away from the equipment rack 8 at the top of the linear guide rail 61. Then drive the extending end of the hydraulic cylinder 7 to continue to extend, pushing the cable protection pipes fixed on both sides to be butted together. Since the top end of the fixed seat 4 and the top end of the first clamping block 533 are on the same horizontal line, the accuracy of the docking position between the two cable protection pipes is ensured through the fixed seat 4 and the clamping component 53. After the docking is completed, start the welding device 9. The welding device 9 performs welding treatment on the docking joint between the two cable protection pipes. When it is necessary to rotate the cable protection pipe during the welding process, start the rotating motor 55. The rotating motor 55 drives the gear 56 to rotate. When the gear 56 rotates, it drives the annular rack 52 meshed on the surface to rotate, causing the annular rack 52 to rotate inside the annular groove of the support frame 51 through the annular guide rails 54 on both sides of the outer surface, driving the cable protection pipe fixed in the clamping component 53 to rotate during the welding process as the welding position changes, enabling the device to directly perform circular welding on the cable protection pipe without adjusting the position after welding a part, re-fixing and then welding again, avoiding multiple position adjustments, resulting in deviation of the welding position and affecting the welding quality of the device, and at the same time avoiding cracking of the welding joint during the adjustment process, effectively improving the welding efficiency of the device.
