[0046] S4. Convey the cable tray rib material, and perform resistance welding on the cable tray rib material through the contact of the electrode plates of the two welding modules.

[0047] The cable tray welding device and its application method of the present invention have the following beneficial effects compared with the prior art:

[0048] (1) By arranging two welding modules, sliding the electrode plates on the frame, and setting multiple limiting components, when the electrode plates move, the applicable limiting end face can be selected through the limiting components to correspond to the electrode plates, so as to realize the limiting of the electrode plates. Firstly, the position change of the electrode plates can be controlled, and secondly, the relative distance between the electrode plates can be adjusted. Thus, the applicable range of the welding device is effectively improved, which is beneficial to the production of cable trays of different models and has the advantage of good versatility;

[0049] (2) A displacement frame is arranged in the welding module, which is used to carry the electrode plates. Relying on the sliding fit between the displacement frame and the frame and abutting against the limiting end face of the limiting component can avoid damage to the electrode plates during the adjustment process;

[0050] (3) An adjusting component is arranged in the welding module to control the distance between adjacent electrode plates. The adjusting component is provided with a traction cable. When the end traction cable is pulled, all the rear traction cables and the swing frame can be driven to move synchronously, so as to realize the adjustment of the distance between all displacement frames and electrode plates, which has the advantage of convenient adjustment;

[0051] (4) In the welding module, a winding component is arranged on the traction cable. By adjusting the winding strength of the winding component, the winding strengths of all winding components can be increased in sequence, which can ensure that each swing frame can stably abut against the displacement frame, so as to ensure the adjustment of all displacement frames and electrode plates and keep their positions stable;

[0052] (5) In the welding module, the displacement frame is clamped by relying on the limiting component and the swing frame of the adjusting component, thereby realizing the fixation of the electrode plate. In this way, after the traction cable at the end is relaxed, the swing frame will become loose, and at this time, the displacement frame and the electrode plate can be directly removed for maintenance, which has the advantage of convenient operation and maintenance.

[0053] (6) In the frame structure, a detection component is arranged on the panel. The detection component can drive the lever to abut against the welded rib by means of the linear module and the sliding frame. In this way, by detecting the swing angle of the lever through the first angle sensor, it is possible to know whether the current solder joint is welded stably, which has the advantage of convenient detection and is conducive to ensuring the quality of the finished product.

[0079] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0080] As Figures 1 to 23 shown, the cable tray welding device of the present invention includes a frame 1, a welding module 2 and a detection component 3, which are used for cross-welding ribs to form a grid-type cable tray.

[0081] Embodiment 1:

[0082] As Figures 1 to 6 shown, two welding modules 2 are oppositely arranged on the frame 1. The welding module 2 includes a plurality of electrode plates 21 and a limiting component 22. Among them, the electrode plates 21 are slidably connected to the frame 1, and the electrode plates 21 of the two welding modules 2 can approach each other relatively; a plurality of limiting components 22 are movably arranged on the frame 1, and the limiting component 22 has three limiting end faces 2201; one of the limiting end faces 2201 is used to keep a plurality of electrode plates 21 at a predetermined distance X1; another limiting end face 2201 is used to keep a plurality of electrode plates 21 at a predetermined distance X1 and change the overall position; and another limiting end face 2201 is used to adjust the predetermined distance between a plurality of electrode plates 21 to X2;

[0083] With the above structure, when the cable tray welding device is applied, the electrode plates 21 adopt an adjustable structure, so that it can adapt to different models of cable trays for welding;

[0084] In this cable tray welding device, the electrode plate 21 is set as an adjustable structure, which is slidably matched with the frame 1 to adjust the spacing and overall position, and the limiting end face 2201 of the limiting component 22 is used to control the relative spacing and overall position of the electrode plate 21;

[0085] See Figure 18 , which is a schematic diagram of a standard bridge welding structure. The longitudinal bars are fed, the transverse bars are placed on the longitudinal bars, and then relying on the electrode plates 21 of the two welding modules 2, the longitudinal bars and the transverse bars are contacted to achieve resistance welding; in the illustrated structure, the electrode plates 21 can contact all the longitudinal bars; among them, one limiting end face 2201 of the limiting component 22 keeps the spacing between the electrode plates 21 at a predetermined spacing X1;

[0086] See Figure 19 , in this structure, the layout interval of the longitudinal bars has changed, and at this time the electrode plates 21 cannot contact all the longitudinal bars. Therefore, after the transverse bars are placed, the electrode plates 21 cannot weld all the intersection points of the longitudinal bars and the transverse bars; at this time, the positions of all the electrode plates 21 need to be adjusted; as shown by the dotted line in the figure, it is the position of the electrode plates 21 after adjustment. At this time, the electrode plates 21 cover all the longitudinal bars, so that after the transverse bars are placed, all the intersection points can be guaranteed to be welded; another limiting end face 2201 of the limiting component 22 keeps the spacing between the electrode plates 21 at a predetermined spacing X1 and the overall position changes;

[0087] See Figure 20 , in this structure, three longitudinal bars are in a group, but the spacing of each group of longitudinal bars has changed. At this time, the electrode plates 21 cannot contact all the longitudinal bars. Under the condition that each electrode plate 21 corresponds to a group of longitudinal bars, the spacing of the electrode plates 21 needs to be controlled; as shown by the dotted line in the figure, it is a schematic diagram of the position of the electrode plates 21 after adjustment. The spacing of the electrode plates 21 has changed, so as to cover all the longitudinal bars to weld all the intersection points of the longitudinal bars and the transverse bars; among them, another limiting end face 2201 of the limiting component 22 keeps the spacing between the electrode plates 21 at a predetermined spacing X2;

[0088] As set in the above related structures, by setting two welding modules 2, slidingly setting the electrode plates 21 on the frame 1, and setting a plurality of limiting components 22, so when the electrode plates 21 move, the applicable limiting end face 2201 can be selected through the limiting component 22 to correspond to the electrode plates 21, so as to realize the limitation of the electrode plates 21. In this way, on the one hand, the position change of the electrode plates 21 can be controlled, and on the other hand, the relative spacing of the electrode plates 21 can be adjusted, thereby effectively improving the applicable range of this welding machine device, being beneficial to producing bridge cables of different models, and having the advantage of good versatility.

[0089] Specifically, the electrode plate 21 in one welding module 2 is the positive electrode plate, and the electrode plate 21 in the other welding module 2 is the negative electrode plate, thereby realizing resistance welding. At the same time, the electrode plate 21 of one of the welding modules 2 is connected to a cylinder, so as to realize the relative approach of the two groups of electrode plates 21.

[0090] In some embodiments, the electrode plates 21 in the two welding modules 2 are both driven by cylinders.

[0091] As Figure 3 、 Figure 7 and Figure 8 shown, the welding module 2 further includes a displacement frame 23 and an adjusting member 24. Among them, a plurality of displacement frames 23 are provided and are slidably connected to the frame 1, and the electrode plate 21 is connected to the displacement frame 23; the adjusting member 24 is provided on the frame 1, and the adjusting member 24 is used to drive the displacement frame 23 to move so that the displacement frame 23 abuts against the limiting end face 2201.

[0092] In the welding module 2 with the above structure, the displacement frame 23 is used to carry the electrode plate 21, so as to drive the electrode plate 21 to move to realize position adjustment. The adjusting member 24 is used as a power source to drive the displacement frame 23, so that the displacement frame 23 can abut against the limiting end face 2201 of the limiting component 22, thereby realizing the positioning work.

[0093] As Figures 8 to 11 shown, the adjusting member 24 includes a swing frame 241, a traction cable 242, a winding assembly 243 and a motor 244. Among them, a plurality of swing frames 241 are provided, and one end of the swing frame 241 is hinged to the frame 1, and the other end corresponds to the displacement frame 23; a plurality of traction cables 242 are provided, and adjacent two swing frames 241 are connected by the traction cable 242, and a winding assembly 243 is arranged in the middle of the traction cable 242; the winding strengths of the plurality of winding assemblies 243 increase in sequence; two motors 244 are oppositely arranged on the frame 1, and the main shafts of the motors 244 are connected to the swing frame 241 through the traction cable 242.

[0094] In the above structure, a plurality of swing frames 241 are arranged on the frame 1, and the plurality of swing frames 241 are connected by a plurality of traction cables 242. Thus, when the motor 244 winds the traction cable 242 at the end, it will drive all the swing frames 241 to swing, and then rely on the swinging end of the swing frame 241 to push the displacement frame 23 to move, thereby realizing the adjustment of the distance between all the electrode plates 21.

[0095] As Figure 10As shown, when the motor 244 on the right side winds up, the motor 244 on the left side unwinds. At this time, all the swing frames 241 swing driven by the traction cable 242 and push all the displacement frames 23 to abut against the limiting component 22, thus realizing the adjustment of the distance between the electrode plates 21; by making the limiting component 22 adopt different limiting end faces 2201 to correspond to the displacement frames 23, the effect that the distance between the electrode plates 21 remains unchanged but the overall position changes is achieved; this structure is applicable to structures such as Figure 19 and Figure 20 shown;

[0096] For Figure 21 the shown implementation structure, it needs to rely on the winding component 243. In this structure, the traction cable 242 serves as a connecting part and plays a main connecting role; the winding component 243 on the traction cable 242 is used to control the telescopic sequence of multiple traction cables 242.

[0097] Such as Figure 10 and Figure 11 shown, if the distance between all the electrode plates 21 is changed, under the traction of the motor 244 on the right side, the winding component 243 located on the far left has the weakest winding strength, and the winding strengths of multiple winding components 243 increase sequentially from left to right;

[0098] In this way, the traction cable 242 with the winding component 243 set on the far left will first drive its corresponding displacement frame 23 to abut against the limiting end face 2201 of a limiting component 22 through a swing frame 241. At this time, the traction cable 242 on the far left continues to be stretched until the second traction cable 242 drives its corresponding displacement frame 23 to abut against the limiting component 22 through the second swing frame 241, and the traction cable 242 on the far left is no longer stressed;

[0099] In this way, multiple traction cables 242 are telescopically extended in sequence under the control of the winding component 243, thus realizing the sequential positions of multiple displacement frames 23 until all the electrode plates 21 are adjusted in place; this structure is beneficial to ensure that all the electrode plates 21 are adjusted in place, thereby avoiding loosening problems;

[0100] In this structure, the displacement frame 23 is clamped and fixed through the swing frame 241 and the limiting component 22 without other fasteners. Therefore, after the motor 244 unwinds, all the displacement frames 23 are loosened simultaneously, which is convenient for subsequent disassembly, adjustment and replacement.

[0101] Such as Figure 22As shown, it shows the spacing structure of the limiting component 22. Among them, X1 is the initial predetermined spacing and the spacing schematic for the overall position change of all the electrode plates 21, X2 is the predetermined spacing after the adjustment of the electrode plates 21; X3 is the relative spacing of the limiting component 22; among them, in the case where X3 remains unchanged, the upper end face of the limiting component 22 is successively retracted, so that the spacing of all the electrode plates 21 can be controlled to be X2.

[0102] Specifically, the winding component 243 can adopt a rewinding mechanism such as a winder with a rewinding spring structure.

[0103] As Figure 10 shown, the adjusting member 24 further includes a limiting cable 245. The predetermined spacing X1 of the plurality of displacement frames 23 is less than the predetermined spacing X2. Two adjacent swing frames 241 are connected by a limiting cable 245 to keep the spacing between the two swing frames 241 as X2;

[0104] As in the above structure, by setting the limiting cable 245, the relative interval of the swing frame 241 can be controlled, thereby avoiding the problem of over-pulling damage; preferably, when the electrode plates 21 adjust the relative spacing to X2, the limiting cable 245 reaches the stretching limit, so the limiting cable 245 is used to control the relative spacing of the swing frame 241 to be X2; specifically, the relative spacing is the relative spacing of the hinge points of two adjacent swing frames 241 and the frame 1.

[0105] As Figure 7 and Figure 11 shown, the displacement frame 23 includes a U-shaped carrier 231, a connecting rod 232 and rollers 233. Among them, the electrode plates 21 are arranged on the U-shaped carrier 231; the connecting rod 232 is connected to the U-shaped carrier 231, and the swing frame 241 corresponds to the connecting rod 232; two rollers 233 are rotatably arranged on both sides of the U-shaped carrier 231, and the rollers 233 are in rolling connection with the frame 1;

[0106] As in the above structure, the displacement frame 23 is used to drive the electrode plates 21 to move. It is connected to the frame 1 through the rollers 233, thereby realizing the movement of the displacement frame 23;

[0107] When the swing frame 241 swings, it abuts against the connecting rod 232, thereby driving the displacement frame 23 and the electrode plates 21 to move;

[0108] In this structure, the connecting rod 232 is installed through the U-shaped carrier 231, so that the movement of the swing frame 241 can be avoided from being interfered;

[0109] As Figure 6 and Figure 9As shown in the figure, the frame 1 includes a rectangular frame 11, an upper bracket 12, a lower bracket 13, a back plate 14 and an end plate 15. Among them, a plurality of upper brackets 12 are arranged on one inner surface of the rectangular frame 11; a plurality of lower brackets 13 are arranged on the other inner surface of the rectangular frame 11, and the lower brackets 13 are arranged opposite to the upper brackets 12; one side edge of the back plate 14 is connected to a plurality of upper brackets 12, and the other side edge is connected to a plurality of lower brackets 13; there are two end plates 15, one of the end plates 15 is connected to a plurality of upper brackets 12, and the other end plate 15 is connected to the lower brackets 13; chutes 101 are arranged on both the back plate 14 and the end plate 15, the rollers 233 are located in the chutes 101, and a first through groove 102 is formed on the back plate 14;

[0110] As described above, the frame 1 is composed of multiple plate frames. Among them, the rectangular frame 11 is the main frame; the upper bracket 12 and the lower bracket 13 are used to install the back plate 14 and the end plate 15, and then the displacement frame 23 is installed through the chutes 101 on the back plate 14 and the end plate 15; the rollers 233 of the displacement frame 23 are set as concave rollers, so that they can be clamped on the back plate 14 and the end plate 15, thus avoiding deviation and ensuring the stability of sliding;

[0111] Among them, the upper bracket 12 and the lower bracket 13 are set as U-shaped frames, and connecting rods are arranged on the back plate 14 and the end plate 15, and then they can be connected and fixed to the upper bracket 12 and the lower bracket 13 through fasteners such as bolts. This structure is convenient for disassembly, installation and maintenance;

[0112] Among them, the first through groove 102 on the back plate 14 is used to supply the longitudinal bars. In this way, the longitudinal bars will pass through between the two welding modules 2, and then the welding work can be carried out.

[0113] As Figure 1 and Figure 6 shown in the figure, the frame 1 further includes a panel 16. The panel 16 is a T-shaped plate. Two opposite side edges of the panel 16 are connected to an end plate 15, and the other side edge abuts against the electrode plate 21. And the panel 16 is provided with a second through groove 103 corresponding to the first through groove 102;

[0114] As described above, the panel 16 is used to further enclose the welding device to protect the internal components. The second through groove 103 on the panel 16 is used for the extension of the longitudinal bars and the input of the transverse bars. After the transverse bars are sent into the welding box through the second through groove 103 and welded, with the feeding of the longitudinal bars, the welded transverse bars can be output together;

[0115] Among them, the panel 16 is set as a trapezoidal plate, and its two opposite side edges can be clamped to the side edges of the end plate 15 through U-shaped grooves, so that it is convenient for subsequent disassembly;

[0116] The other side edge of the panel 16 abuts against the electrode plate 21 of the lower welding module 2, so as to facilitate the support of the reinforcement materials.

[0117] like Figures 12 to 15 As shown, the detection component 3 includes a sliding frame 31, a first angle sensor 32, a rotating shaft 33, a lever 34, a first limiting plate 35, a second limiting plate 36, a tension spring 37 and a linear module 38, wherein a third through slot 104 is provided on the panel 16, and the third through slot 104 is parallel to the second through slot 103; the sliding frame 31 is slidably arranged in the third through slot 104; the first angle sensor 32 is arranged on the sliding frame 31, and a rotating shaft 33 is rotatably arranged on the first angle sensor 32; one end of the lever 34 is connected to the rotating shaft 33, and the other end faces the second through slot 103; the first limiting plate 35 and the second limiting plate 36 are arranged on the sliding frame 31, the first limiting plate 35 resists the lever 34, and the second limiting plate 36 is connected to the lever 34 through a tension spring 37; the linear module 38 is arranged on the panel 16, and the movable end of the linear module 38 is connected to the sliding frame 31;

[0118] As in the above structure, in order to ensure the welding quality of the bridge, a detection component 3 is provided to detect the strength of the welding point;

[0119] Specifically, in the structure shown in the figure, the detection component 3 is located above the second through slot 103, and is suitable for detecting the bridge frame with the longitudinal reinforcement on the top;

[0120] During the inspection, the linear module 38 drives the other components of the inspection assembly 3 to move until the lever 34 abuts against the longitudinal rib. At this time, the lever 34 is stressed, but the sliding frame 31 still moves, so the lever 34 rotates at an angle. If the angle detected by the first angle sensor 32 is the predetermined angle, it means that the welding point is stable.

[0121] If the welding point is unstable, the tension generated by the tension spring 37 on the lever 34 will cause the longitudinal rib to deviate to a certain extent, and the angle detected by the first angle sensor 32 is not the predetermined angle;

[0122] In this way, it is possible to detect whether the welding point is stably welded; wherein the second limit plate 36 is used to install the tension spring 37, and the first limit plate 35 is used to limit the predetermined angle of the lever 34.

[0123] In some embodiments, the detection component 3 is placed below the second through slot 103, so that the transverse ribs can be supplied from the upper portion, and the detection component 3 can conveniently perform a detection on the longitudinal ribs below.

[0124] In some embodiments, the side of the frame 1 is slotted to facilitate the supply of the cross ribs through one side to avoid interference with the detection component 3.

[0125] like Figure 3As shown in the figure, the limit component 22 includes a cylinder 221, a support plate 222 and a limit frame 223. Among them, the cylinder 221 is connected to the frame 1; the support plate 222 is arranged on the movable end of the cylinder 221; the limit frame 223 is arranged on the support plate 222, and the limit frame 223 has a stepped structure to form a limit end face 2201;

[0126] In the above structure, the limit component 22 relies on the limit frame 223 to abut against the connecting rod 232 of the displacement frame 23, thereby realizing the limit of the electrode plate 21;

[0127] Among them, the limit frame 223 is set to a stepped structure, so that three or more limit end faces 2201 can be formed for the limit of the displacement frame 23; the cylinder 221 drives all the limit frames 223 to move through the support plate 222, so as to adjust the height of different limit end faces 2201, and then correspond to the displacement frame 23.

[0128] In some embodiments, as Figure 23 shown, between the adjacent limit end faces 2201 of the limit frame 223, there is an inclined surface. In this way, by continuously lifting the limit frame 223 by the cylinder 221, it can cooperate with the connecting rod 232 of the displacement frame 23 to make the displacement frame 23 slide and reset, which is convenient for the next adjustment.

[0129] Embodiment Two:

[0130] As Figures 16 to 18 shown, the detection mechanism adopted in this embodiment is different from that in Embodiment One;

[0131] The detection structure in this embodiment includes a torque motor 41, a detection rod 42, a connecting frame 43 and a second angle sensor 44; among them, the torque motor 41 is connected to the panel 16, the detection rod 42 is arranged on the main shaft of the torque motor 41, the angle sensor 44 is connected to the panel 16 through the connecting frame 43, and at the same time the main shaft of the torque motor 41 is set to a spline shaft structure and is connected to the main shaft of the angle sensor 44. In this way, when the main shaft of the torque motor 41 rotates, the angle detection can be realized by relying on the angle sensor 44;

[0132] In such a structure, when the welding is preset to be stable, the detection angle of the second angle sensor 44 is X1, and the torque detected by the torque motor 41 is N1; during the detection, the torque motor 41 is relied on to drive the detection rod 42 to deflect the longitudinal bars. If the angle is stable at X1 after the detection rod 42 abuts against the longitudinal bars, and the torque motor 41 can continuously output torque to N1, it means that the solder joint is stable;

[0133] If the solder joint is unstable, the detection angle is not X1, and the output torque N1 will also change; thereby, the detection of whether the solder joint is stable is realized.

[0134] The application method of the cable tray welding device of the present invention includes the following steps:

[0135] S1. Pre-adjust the limiting end face 2201 of the limiting component 22 to correspond to the displacement frame 23 with a suitable limiting end face 2201;

[0136] S2. Drive multiple displacement frames 23 and plates 21 to move with the adjusting component 24;

[0137] S3. Make the displacement frame 23 abut against the limiting end face 2201 to keep the positions of all plates 21 relatively fixed;

[0138] S4. Convey the cable tray ribs, and perform resistance welding on the cable tray ribs by contacting the plates 21 of the two welding modules 2.

[0139] Specific implementation steps:

[0140] First, drive the limiting frame 223 to rise and fall by the air cylinder 221, and select a suitable limiting end face 2201 to correspond to the displacement frame 23;

[0141] Rely on the motor 244 to wind up the traction cable 242, so that the swing frame 241 drives the displacement frame 23 to move in place, and the distance adjustment between the plates 21 is realized;

[0142] Then supply the longitudinal ribs and transverse ribs, and the two groups of plates 21 approach each other relatively to realize resistance welding;

[0143] Finally, rely on the detection component 3 to realize the stability detection of the welding points.

[0144] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
