[0026] Currently, before installing concrete bridge decks with under-bridge spaces, it is necessary to weld the intersections between longitudinal support beams and transverse beams, and to install slag collection boxes to collect welding slag. However, traditional slag collection boxes are made by directly welding steel plates, and the enclosure area is fixed. Welders find it difficult to select the appropriate collection box according to the actual welding length, resulting in poor effect in preventing welding slag from splashing and inability to collect welding slag effectively.

[0027] To address the problem of poor effectiveness in preventing welding slag spatter, this application provides a welding slag collection device, which includes: a crossbeam and a support beam, the support beam being fixed to the crossbeam and perpendicular to the crossbeam; a first bending member located above the crossbeam, the first bending member having a fixed first hook, the first hook engaging with the support beam so that the first bending member hangs on the support beam, the first bending member including a first folding plate and a second folding plate, one end of the first folding plate being connected to one end of the second folding plate and forming an included angle, the other end of the first folding plate being abutted against the front side of the support beam; and the second folding plate... The extension direction of the folded plate is parallel to the length direction of the support beam. A groove is provided on the side of the second folded plate near the support beam. The second bent piece is located above the crossbeam and is fixed with a second hook. The second hook engages with the support beam so that the second bent piece hangs on the support beam. The second bent piece includes a third folded plate and a fourth folded plate. One end of the third folded plate and one end of the fourth folded plate are connected and have an included angle. The other end of the third folded plate is attached to the front side of the support beam. The extension direction of the fourth folded plate is parallel to the length direction of the support beam. The fourth folded plate is slidably connected to the groove. According to the solution provided in the embodiments of this application, firstly, a support beam is fixed on a crossbeam, and the support beam is perpendicular to the crossbeam. Then, a first bent component is located above the crossbeam, and a first hook is fixed to the first bent component. The first hook engages with the support beam so that the first bent component hangs on the support beam. A second bent component is located above the crossbeam, and a second hook is fixed to the second bent component. The second hook engages with the support beam so that the second bent component hangs on the support beam. This improves the stability of the first and second bent components and prevents them from falling from above the crossbeam. The first bent component includes a first folding plate and a second folding plate. One end of the first folding plate and one end of the second folding plate are connected and have an included angle. The other end of the first folding plate is attached to the front side of the support beam. The extension direction of the second folding plate is parallel to the length direction of the support beam. Correspondingly, the second bending component includes a third folding plate and a fourth folding plate. One end of the third folding plate and one end of the fourth folding plate are connected and have an included angle. The other end of the third folding plate is attached to the front side of the support beam. The extension direction of the fourth folding plate is parallel to the length direction of the support beam. Since a groove is provided on the side of the second folding plate near the support beam, and the fourth folding plate is slidably connected to the groove, the relative movement between the second folding plate and the fourth folding plate can make the first folding plate and the third folding plate move closer or further apart. This allows the welder to dynamically adjust the range of slag protection according to the actual welding length between the support beam and the crossbeam, improve the effect of preventing slag spatter, and better collect slag.

[0028] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the welding slag collection device provided in the embodiments of this application. Figure 2This is a schematic diagram of the specific structure of the welding slag collection device provided in the embodiments of this application. Figure 3 This is a schematic diagram of the structure of the first bend and the second bend provided in an embodiment of this application. This embodiment of the application provides a welding slag collection device, including:

[0030] A crossbeam 100 and a support beam 200 are provided. The support beam 200 is fixed to the crossbeam 100 and is perpendicular to the crossbeam 100.

[0031] The first bending member 300 is located above the crossbeam 100. The first bending member 300 is fixed with a first hook 500. The first hook 500 engages with the support beam 200 so that the first bending member 300 hangs on the support beam 200. The first bending member 300 includes a first folding plate 310 and a second folding plate 320. One end of the first folding plate 310 and one end of the second folding plate 320 are connected and have an included angle. The other end of the first folding plate 310 is attached to the front side of the support beam 200. The extension direction of the second folding plate 320 is parallel to the length direction of the support beam 200. A groove 330 is provided on the side of the second folding plate 320 near the support beam 200.

[0032] The second bending member 400 is located above the crossbeam 100. The second bending member 400 is fixed with a second hook 600, which engages with the support beam 200 so that the second bending member 400 hangs on the support beam 200. The second bending member 400 includes a third folding plate 410 and a fourth folding plate 420. One end of the third folding plate 410 and one end of the fourth folding plate 420 are connected and have an included angle. The other end of the third folding plate 410 is attached to the front side of the support beam 200. The extension direction of the fourth folding plate 420 is parallel to the length direction of the support beam 200. The fourth folding plate 420 is slidably connected to the slide groove 330.

[0033] The included angle between the first fold plate 310 and the second fold plate 320 is equal to the included angle between the third fold plate 410 and the fourth fold plate 420. In addition, the included angle between the first fold plate 310 and the second fold plate 320 and the included angle between the third fold plate 410 and the fourth fold plate 420 can be right angle, acute angle or obtuse angle, and the embodiments disclosed herein are not limited thereto.

[0034] The first folding plate 310 and the third folding plate 410 can be straight panels or curved panels, respectively, and this embodiment of the present disclosure is not limited thereto.

[0035] The cross-sectional shape of both the crossbeam 100 and the support beam 200 is rectangular.

[0036] Among them, the first fold plate 310, the second fold plate 320, the third fold plate 410 and the fourth fold plate 420 are all perpendicular to the upper plane of the crossbeam 100.

[0037] It should be noted that the first bending member 300 and the second bending member 400 may or may not be attached to the crossbeam 100, and this embodiment of the present disclosure does not limit the specific attachments.

[0038] Based on this, firstly, the support beam 200 is fixed to the crossbeam 100, and the support beam 200 is perpendicular to the crossbeam 100. Then, the first bending member 300 is located above the crossbeam 100, and the first bending member 300 is fixed with a first hook 500, which engages with the support beam 200 so that the first bending member 300 hangs on the support beam 200. Secondly, the second bending member 400 is located above the crossbeam 100, and the second bending member 400 is fixed with a second hook 600. The first bent component 300 engages with the support beam 200 so that the second bent component 400 hangs on the support beam 200, which can improve the stability of the first bent component 300 and the second bent component 400 and prevent them from falling from above the crossbeam 100. The first bent component 300 includes a first folding plate 310 and a second folding plate 320. One end of the first folding plate 310 and one end of the second folding plate 320 are connected and have an included angle. The other end of the first folding plate 310 is connected to the support beam 200. The front side of the support beam 200 is attached, and the extension direction of the second folding plate 320 is parallel to the length direction of the support beam 200. Correspondingly, the second bending member 400 includes a third folding plate 410 and a fourth folding plate 420. One end of the third folding plate 410 and one end of the fourth folding plate 420 are connected and have an included angle. The other end of the third folding plate 410 is attached to the front side of the support beam 200, and the extension direction of the fourth folding plate 420 is parallel to the length direction of the support beam 200. Since the second folding plate 320 is provided with a groove 330 on the side near the support beam 200, and the fourth folding plate 420 is slidably connected to the groove 330, the relative movement between the second folding plate 320 and the fourth folding plate 420 can make the first folding plate 310 and the third folding plate 410 move closer or further apart. This allows the welder to dynamically adjust the range of slag protection according to the actual welding length between the support beam 200 and the crossbeam 100, improve the effect of preventing slag spatter, and better collect slag.

[0039] In one possible implementation, both the second fold plate 320 and the fourth fold plate 420 are curved panels, and the bending direction and bending amplitude of the second fold plate 320 and the fourth fold plate 420 are the same. Correspondingly, the sliding groove 330 has the same bending direction and bending amplitude as the second fold plate 320.

[0040] In one possible implementation, the second folding plate 320 is provided with a groove 330 on the side away from the support beam 200.

[0041] Additionally, refer to again Figures 1 to 3In some embodiments of this application, the first hook 500 is fixed at the connection between the first folding plate 310 and the second folding plate 320, and the second hook 600 is fixed at the connection between the third folding plate 410 and the fourth folding plate 420.

[0042] The first hook 500 can be set on the side of the second folding plate 320 away from the support beam 200, and the second hook 600 can be set on the side of the fourth folding plate 420 away from the support beam 200.

[0043] Based on this, the first hook 500 is fixed at the connection between the first folding plate 310 and the second folding plate 320, and the second hook 600 is fixed at the connection between the third folding plate 410 and the fourth folding plate 420, so that the stress of the first hook 500 on the first folding plate 310 and the second folding plate 320 is similar, and the stress of the second hook 600 on the third folding plate 410 and the fourth folding plate 420 is similar, which can further increase the stability of the first bending part and the second bending part, thereby improving the overall stability of the welding slag collection device.

[0044] Additionally, refer to again Figures 1 to 3 In some embodiments of this application, the first hook 500 includes a first positioning post 510, a second positioning post 520 and a third positioning post 530 connected in sequence. The first positioning post 510 is vertically disposed on the second folding plate 320, the second positioning post 520 is disposed above the support beam 200, and the third positioning post 530 is vertically disposed on the rear side of the support beam 200.

[0045] The first positioning post 510 can be set on the side of the second folding plate 320 away from the support beam 200.

[0046] The bottom end of the first positioning post 510 is flush with the bottom end of the second folding plate 320.

[0047] The first positioning post 510 does not fit against the side of the support beam 200, while the third positioning post 530 fits against the side of the support beam 200.

[0048] It should be noted that the second hook 600 includes a fourth positioning post 610, a fifth positioning post 620 and a sixth positioning post 630 connected in sequence. The configuration of the second hook 600 is the same as that of the first hook 500, and will not be described in detail here.

[0049] Based on this, the first hook 500 includes a first positioning post 510, a second positioning post 520 and a third positioning post 530 connected in sequence. The first positioning post 510 is vertically arranged on the second folding plate 320, the second positioning post 520 is arranged above the support beam 200, and the third positioning post 530 is vertically arranged on the rear side of the support beam 200. This can prevent the welding slag receiving device from being displaced undesirably in the length direction of the crossbeam 100, improve the overall stability of the welding slag collection device, and prevent welding slag leakage when adjusting the enclosure range.

[0050] Additionally, refer to again Figures 1 to 3 In some embodiments of this application, the second positioning post 520 is parallel to the length direction of the crossbeam 100.

[0051] Based on this, the first hook 500 converts the weight of the first folding plate 310 into a force that makes the first folding plate 310 press against the support beam 200, and converts the weight of the third folding plate 410 into a force that makes the third folding plate 410 press against the support beam 200. The second positioning post 520 is parallel to the length direction of the crossbeam 100, which can increase the conversion of the force of the first folding plate 310 pressing against the support beam 200 and the force of the third folding plate 410 pressing against the support beam 200. This can prevent the welding slag receiving device from moving in the length direction of the crossbeam 100, improve the overall stability of the welding slag collection device, and thus prevent welding slag leakage when adjusting the enclosure range.

[0052] Additionally, refer to again Figures 1 to 3 In some embodiments of this application, the length of the first positioning post 510 is greater than the length of the third positioning post 530.

[0053] Based on this, the length of the first positioning post 510 is greater than the length of the third positioning post 530, so that the welding slag collection device can be disassembled without having to move it to a higher height, which can improve the ease of use of the welding slag collection device.

[0054] Additionally, refer to again Figures 1 to 3 and reference Figure 4 , Figure 4 The diagram below shows the structure of the limiting bolt provided in the embodiments of this application. In some embodiments of this application, the slag collection device further includes a limiting bolt 340, and the slide 330 is provided with a threaded through hole that matches the limiting bolt 340. The limiting bolt 340 is threadedly connected to the threaded through hole.

[0055] The threaded through hole is located on the side of the second folding plate 320 away from the first folding plate 310, and the axial direction of the threaded through hole is perpendicular to the upper plane of the crossbeam 100.

[0056] The nut of the limiting bolt 340 is polygonal, which allows welders to tighten or loosen the limiting bolt 340 without the need for tools.

[0057] Based on this, the welding slag collection device also includes a limiting bolt 340. The slide 330 is provided with a threaded through hole that matches the limiting bolt 340. The limiting bolt 340 is threadedly connected to the threaded through hole. The position that the fourth folding plate 420 can slide in the slide 330 can be controlled by the tightness of the limiting bolt 340. This enables the fourth folding plate 420 to be fixedly connected to the second folding plate 320, thereby improving the stability of the welding slag collection device.

[0058] Additionally, refer to again Figures 1 to 3 In some embodiments of this application, the side shapes of the first folding plate 310, the second folding plate 320, the third folding plate 410, and the fourth folding plate 420 are all rectangular.

[0059] Based on this, the side shapes of the first folding plate 310, the second folding plate 320, the third folding plate 410 and the fourth folding plate 420 are all rectangular, which can improve the fit between the welding slag collection device and the crossbeam 100, thereby improving the stability of the welding slag collection device and preventing welding slag leakage when adjusting the enclosure range.

[0060] Additionally, refer to again Figures 1 to 3 In some embodiments of this application, a support plate 210 is connected to the side of the support beam 200 near the first bending member 300. The bottom surface of the support plate 210 is on the same plane as the bottom surface of the support beam 200. The distance between the two ends of the first bending plate 310 and the distance between the two ends of the second bending plate 320 are both greater than the width of the support plate 210. The bottom of the first bending plate 310 and the third bending plate 410 are provided with notches 350 that match the support plate 210.

[0061] Based on this, the distance between the two ends of the first folding plate 310 and the distance between the two ends of the second folding plate 320 are both greater than the width of the support plate 210. The bottom of the first folding plate 310 and the third folding plate 410 are provided with notches 350 that match the support plate 210, which can further make the enclosure space at the bottom of the welding slag collection device more compact, so as to prevent welding slag leakage when adjusting the enclosure range.

[0062] Additionally, refer to again Figure 3 In some embodiments of this application, the number of slides 330 is two, and the two slides 330 are respectively disposed at the top and bottom of the second folding plate 320.

[0063] The groove 330 located at the top of the second folding plate 320 is recessed upwards, and the groove 330 located at the bottom of the second folding plate 320 is recessed downwards.

[0064] Based on this, two chutes 330 are respectively set at the top and bottom of the second folding plate 320, and match the top and bottom of the fourth folding plate 420 respectively, which can improve the stability of the welding slag collection module during the adjustment of the enclosure range.

[0065] Additionally, refer to again Figures 1 to 3 In some embodiments of this application, the first folding plate 310 is perpendicular to the second folding plate 320, the third folding plate 410 is perpendicular to the fourth folding plate 420, and the first folding plate 310 is parallel to the third folding plate 410.

[0066] Based on this, the first folding plate 310 is perpendicular to the second folding plate 320, the third folding plate 410 is perpendicular to the fourth folding plate 420, and the first folding plate 310 is parallel to the third folding plate 410, so that the enclosure space forms a cube, maximizing the enclosure range within a limited space and improving the effect of preventing welding slag spatter.

[0067] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
