[0061] Reference Figure 1~Figure 5 An embodiment of the present invention provides a sound insulation barrier welding device, including a body 1, a first slide 2 is lifted and slidably arranged on the body 1, a second slide 3 is lifted and slidably arranged on the first slide 2, two first clamping assemblies 4 are respectively arranged on the first slide 2 and the second slide 3, and a clamping space 401 is formed between the two first clamping assemblies 4, a second clamping assembly 5 is lifted and slidably arranged on the second slide 3, and the second clamping assembly 5 is located on one side of the clamping space 401, one end of a vertical slide 6 is arranged on the first slide 2, and the vertical slide 6 is slidably arranged on the second slide 3, and the first clamping assembly 4 and the second clamping assembly 5 are respectively located on both sides of the vertical slide 6.

[0062] In this embodiment, considering that the I-beam is long, it is difficult to fix the fixed foot block in a precise position and perform subsequent welding and installation. This solution is mainly aimed at the welding of T-shaped fixed foot blocks, and is designed with a first slide 2 and a second slide 3. The two slides each have a protruding portion parallel to the ground, which is convenient for the installation of subsequent structures. A first clamping assembly 4 is also designed. The first clamping assembly 4 is arranged in pairs. After the second slide 3 slides on the first slide 2, the clamping space 401 is reduced. The first clamping assembly 4 is used to clamp the two sides of the I-beam. While clamping one end of the I-beam, the device can also be adaptively adjusted according to the position and size of the I-beam. This solution is also designed with a second clamping assembly 5, which is used to fix the fixed foot block.

[0063] The operation process of this scheme is to first clamp the fixed foot block on the second clamping assembly 5, then raise the first slide 2 to abut the bottom of the I-beam, and then slide the second slide 3 to abut the top of the I-beam. When the abutment is not completely clamped, move the device to the fixed foot block abutting the I-beam. The abutting position is the position where the foot block and the I-beam need to be welded. The vertical slide frame 6 provides a positioning guide for the welding tool. After the fixed foot block abuts the I-beam, the vertical slide frame 6 is on both sides of the part to be welded. The design of this scheme can clamp and position the upper and lower planes of the I-beam, and also clamp and position the stable clamping position of the fixed foot block. The setting of the two sets of moving components makes the positioning and placement before welding more accurate, reduces the difficulty of welding, and avoids the need to manually adjust and position the fixed foot block multiple times during welding in the prior art. While improving the accuracy, it also improves the efficiency of the welding process.

[0064] Furthermore, it also includes a first rack 7 arranged on the second clamping assembly 5, a second rack 8 arranged on the second slide 3 and located on one side of the first rack 7, a first gear 9 rotatably arranged on the first slide 2, the first gear 9 is meshed with the first rack 7, a second gear 10 is rotatably arranged on the first slide 2, and is coaxially arranged with the first gear 9 and rotates synchronously, and the second gear 10 is meshed with the second rack 8.

[0065] In this embodiment, considering that when welding the T-shaped fixed foot block, it is necessary to align the top surface of the fixed foot block and one end of the I-beam before welding, this scheme is designed with two sets of gear racks, the first gear 9 and the second gear 10 are coaxially arranged to rotate synchronously, and the module of the first gear 9 is smaller than the module of the second gear 10. When the second slide 3 slides up and down on the first slide 2, the second rack 8 drives the second gear 10 to rotate, and the first gear 9 and the second gear 10 rotate coaxially. Since the modules of the first gear 9 and the second gear 10 are different, the module ratio is set to be that after the second gear 10 is transmitted to the first gear 9, the linear speed of the first gear 9 is half of the second gear 10, so that after the second slide 3 slides on the first slide 2, the moving distance of the second clamping assembly 5 is only half of the second slide 3. After sliding, the second clamping assembly 5 is always located between the two first clamping assemblies 4, that is, the fixed foot block is always able to perform the effect of vertical centering positioning on the surface to be welded of the I-beam.

[0066] Further, the first clamping assembly 4 includes a first sliding shell, a first slider 403 is slidingly arranged on the first sliding shell 402 along the horizontal direction, a claw member 404 is rotatably arranged on the first slider 403, a second slider 405 is lifted and slidably arranged on the first slider 403, a third gear 406 is arranged on the claw member 404, a third rack 407 is arranged on the second slider 405, the third gear 406 is meshed with the third rack 407, and the second slider 405 drives the claw member 404 to rotate after being lifted and moved, one end of the first elastic member 408 acts on the first slider 403, and the other end acts on the second slider 405, providing force for the second slider 405 to slide upward.

[0067] In this embodiment, the first sliding shells 402 of the two first clamping assemblies 4 are respectively disposed on the first sliding bracket 2 and the second sliding bracket 3 . The second slider 405 is provided for detecting the fixed abutment state of the I-beam. After the I-beam abuts the second slider 405, the second slider 405 slides up and down on the first slider 403. The third rack 407 on the second slider 405 drives the third gear 406 to rotate, that is, drives the claw member 404 to rotate. After the rotation, the claw member 404 can be clamped at the bottom of the side groove of the I-beam, which can prevent the I-beam from sliding left and right and limit the upward tilting. As the extrusion process of the I-beam and the second slider 405 gradually proceeds, the clamping process of the I-beam by the claw member 404 is gradually completed, and the clamping is gradually performed and the clamping is completed at the end point. It can be achieved that the position of the device can still be adjusted during the clamping process, so as to achieve the final clamping positioning of the I-beam after the fixed foot block and the I-beam are completely abutted, so that the alignment process of the fixed foot block and the I-beam can be adjusted to prevent the fixed foot block and the I-beam from being incompletely or incorrectly connected after clamping.

[0068] Furthermore, the second clamping assembly 5 includes a second sliding shell 501 slidably arranged on the first sliding frame 2, a first rack 7 arranged on the second sliding shell 501, an upper clamp plate 502 and a lower clamp plate 503 are both lifted and slidably arranged on the second sliding shell 501, and the lower clamp plate 503 is located below the upper clamp plate 502, one end of the telescopic frame 504 is arranged at the bottom of the upper clamp plate 502, and the other end is arranged at the top of the lower clamp plate 503, two ends of the telescopic slide 505 are respectively horizontally slidably arranged on the upper clamp plate 502 and the lower clamp plate 503, the telescopic slide 505 is located on one side of the telescopic frame 504, one end of the second elastic member 506 acts on the upper clamp plate 502, and the other end acts on the lower clamp plate 503, providing a force for the upper clamp plate 502 and the lower clamp plate 503 to approach each other, and one end of the third elastic member 507 acts on the telescopic frame 504, and the other end acts on the telescopic slide 505, providing a force for the telescopic slide 505 to move away from the telescopic frame 504.

[0069] In this embodiment, considering that the fixed foot block needs to be centered, this solution is designed with a second sliding shell 501, a sliding arrangement between the upper clamping plate 502 and the lower clamping plate 503 that moves closer or farther from each other, and the upper and lower clamping plates 503 are used to clamp the supporting foot of the T-shaped foot block. The second elastic member 506 is set so that the upper and lower clamping plates 503 can maintain the reset force when they move closer or farther away. The telescopic frame 504 and the telescopic slide 505 are set to align the two ends of the foot block. The telescopic frame 504 and the telescopic slide 505 are both set to be vertically retractable. The foot block is positioned by the cooperation of the paired telescopic slide 505 and the third elastic member 507. The telescopic frame 504 provides a guide for the upper clamping plate 502 and the lower clamping plate 503, and provides support for the third elastic member 507.

[0070] Furthermore, each first clamping assembly 4 has two first sliders 403 arranged in pairs, and move closer to or away from each other after sliding. It also includes a fourth elastic member 11, which acts on the two first sliders 403 respectively to provide a force to move the two first sliders 403 away from each other.

[0071] In this embodiment, the first sliders 403 are arranged in pairs on each first clamping assembly 4, and the claw members 404 are also arranged in pairs. The claw members 404 are set so that the claw members 404 at both ends need to slide outwards a certain distance to achieve the clamping of the bottom of the I-beam. When the claw members 404 are inserted into the grooves on the sides of the I-beam, the first sliders 403 slide outwards. The setting of the fourth elastic member 11 provides a reset force for the first slider 403 on the one hand, and on the other hand, makes the claw members 404 on both sides clamped more tightly, so that the device is more adaptable to the shape of the I-beam.

[0072] Further, it also includes: a transverse sliding frame 12, the transverse sliding frame 12 is horizontally and lifted and slidably arranged on the vertical sliding frame 6, the transverse sliding frame 12 has a first through slot 1201, the vertical sliding frame 6 is located in the first through slot 1201, the transverse sliding frame 12 includes an outer transverse sliding frame 1202 horizontally and lifted and slidably arranged on the vertical sliding frame 6, and an inner transverse sliding frame 1203 is horizontally slidably arranged in the outer transverse sliding frame 1202,

[0073] In this embodiment, the transverse sliding frame 12 is raised and lowered on the vertical sliding frame 6. After the two first clamping assemblies 4 clamp the I-beam, the transverse sliding frame 12 is raised and lowered on the vertical sliding frame 6 to adjust the position according to the thickness of the I-beam, so that the transverse sliding frame can always position the welding position well, and the transverse sliding frame provides a precise and stable guide for the welding tool. During the sliding process of the first sliding block 403, the outer transverse sliding frame 1202 and the inner transverse sliding frame 1203 produce a telescopic effect, and the guide position can be adaptively adjusted.

[0074] Further, the first sliding shell 402 has a second through groove 409, the first slider 403 is slidably set in the second through groove 409, and also includes a fourth gear 13 rotatably set on the first sliding shell 402, located in the second through groove 409, the fourth rack 14 is set on the first slider 403, the fourth rack 14 is meshed with the fourth gear 13, the fifth rack 15 is set on the inner transverse sliding frame 1203, the sixth rack 16 is set on the outer transverse sliding frame 1202, the fifth gear 17 is coaxially arranged with the fourth gear 13, and the fifth gear 17 is meshed with the fifth rack 15, and the sixth gear 18 is meshed with the sixth rack 16.

[0075] In this embodiment, when the first slider 403 slides outward from the first sliding shell 402, the fourth rack 14 drives the fourth gear 13 and the fifth gear 17 coaxially and synchronously rotated with the fourth gear 13, and the fifth gear 17 and the sixth gear 18 are meshed, and the diameters and tooth thicknesses of the fifth gear 17 and the sixth gear 18 are different, so that the fifth gear 17 can mesh with the fifth rack 15 arranged on the inner transverse sliding frame 1203 at the same time, and also drive the sixth gear 18 to rotate, and the sixth gear 18 meshes with the sixth rack 16 arranged on the outer transverse sliding frame 1202, so as to drive the inner transverse sliding frame 1203 to slide outward from the outer transverse sliding frame 1202. The extension of the first slider 403 is determined by the distance between the claws of the two claw members 404. The I-beam is a standard part, and the distance between the two claw members 404 can reflect the width of the cross section of the I-beam. This design of the device enables the transverse sliding frame 12 to have an effect of equal extension, so that the length of the sliding frame that can provide a guide for the welding tool can be adjusted accordingly, so as to achieve precise fixed-length welding. At the same time, the outer transverse sliding frame 1202 and the inner transverse sliding frame 1203 are driven to move respectively, so that the midpoint of the transverse sliding frame 12 can always be kept in a position aligned with the center line of the I-beam, ensuring the accuracy and controllability of the welding process.

[0076] Furthermore, both the vertical sliding frame 6 and the horizontal sliding frame 12 have a slide rail 601 and a welding member 19 , and the welding member 19 is slidably disposed in the slide rail 601 .

[0077] In this embodiment, the welding member 19 is slidably disposed on the slide rails 601 of the vertical slide frame 6 and the horizontal slide frame 12 , and as the length of the slide rail 601 changes, the travel of the welding member 19 also changes.

[0078] Furthermore, the claw member 404 is configured to be arc-shaped, and further includes rollers 20 rotatably disposed at both ends of the claw member 404 , and a universal wheel 21 rotatably disposed on the second slider 405 .

[0079] In this embodiment, rollers 20 are arranged at both ends of the claw member 404 to prevent the abutting force between the claw member 404 and the I-beam from being too large, resulting in inaccurate position adjustment of the sliding frame, thereby causing errors in the welding process. Universal wheels 21 are arranged at the position where the second slider 405 contacts the I-beam to prevent errors caused by sliding friction and workpiece wear.

[0080] Furthermore, the vertical sliding frame 6 and the horizontal sliding frame 12 are arranged in pairs, and a welding piece 19 is arranged on each of the vertical sliding frame 6 and the horizontal sliding frame 12 .

[0081] In this embodiment, the vertical sliding frame 6 and the horizontal sliding frame 12 are arranged in pairs, so that the welding process can be completed after the welding piece 19 is moved from one side of the sliding frame to the other side, further improving the welding efficiency.

[0082] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
