Description

Technical Field

[0001] This application relates to the field of ladder-type cable tray welding technology, and more particularly to a welding device for ladder-type cable trays. Background Technology

[0002] Ladder-type cable trays are formed by placing two ladder sides parallel to each other, then placing multiple ladder liners at intervals along the length of the two ladder sides, and finally welding the two ends of the multiple ladder liners to the two ladder sides respectively.

[0003] Currently, welding ladder-type cable trays involves manually placing multiple ladder liners into predetermined positions after setting up two ladder sides, followed by welding. This manual placement of each liner is labor-intensive. Current welding equipment operates by first positioning and fixing all liners to the ladder sides, placing multiple lines individually at their designated welding positions, and then welding sequentially. This results in the welding equipment's length being equal to the length of the ladder side of the cable tray. For example, for a 12-meter ladder-type cable tray, the welding area of ​​the equipment needs to be 12 meters long, the feeding end needs to be over 12 meters long, and the discharge end also needs to be 12 meters long, requiring at least 36 meters of space – a very large footprint. Furthermore, the ladder liners are U-shaped or C-shaped cross-section structures with grooves on one side, requiring each of the three sides of one end of the liner to be welded to the inner wall of the ladder side, making manual operation complex. In addition, after the ladder edge and the ladder lining are welded, painting is required. The current welding equipment for ladder cable trays does not have a painting device, so the welded ladder cable trays need to be painted manually, which increases labor costs. Summary of the Invention

[0004] The purpose of this application is to address the above problems by providing a welding device for ladder-type cable trays. The device stores and automatically feeds materials through a material storage device, and integrates a welding device, a cooling device, and a painting device. It has a high degree of overall functional integration and reduces labor costs.

[0005] This application provides a welding device for a ladder-type cable tray. The welding device for the ladder-type cable tray includes a main frame, which includes two parallel support platforms. A storage device, a welding device, a cooling device, and a painting device are sequentially arranged at corresponding positions along the length of each of the two support platforms. The two storage devices can abut against both ends of the ladder liners to stack and store multiple ladder liners parallel to the horizontal plane and to convey the multiple ladder liners downwards one by one. The grooves of the multiple ladder liners all face the feed end of the welding device. The ladder liners and ladder edges pass sequentially through the welding device, the cooling device, and the painting device of the welding device.

[0006] According to the technical solutions provided in certain embodiments of this application, the welding equipment for the ladder-type cable tray further includes:

[0007] Two adjustment platforms are respectively set at corresponding positions of two support platforms. Each adjustment platform includes a sliding table, a sliding seat, and a plurality of third support columns.

The plurality of third support columns are spaced apart along the length direction of the support platform, and the upper ends of the plurality of third support columns are all connected to the lower surface of the sliding table. The material storage device is connected to the sliding seat.

[0008] Two conveying devices are respectively positioned at corresponding positions on the two support platforms. The conveying devices are capable of reciprocating along the length of the support platforms to convey the lower ladder liner of the storage device to the welding device.

One of the two support platforms is slidably connected to the plurality of slide rails.

[0011] According to the technical solutions provided in certain embodiments of this application, the storage device includes:

[0012] A storage bin, perpendicular to a horizontal plane, has a sidewall with a groove along its height. Multiple ladder liners extend through the groove into the interior of the storage bin and abut against its inner wall, allowing them to be stacked along the groove. The multiple ladder liners are parallel to the horizontal plane and can slide downwards along the groove. The grooves of the multiple ladder liners face the sidewall of the storage bin. A through-slot is provided at the bottom of the storage bin to form a flipping area between the lower part of the sidewall and the bottom wall of the storage bin.

[0018] A flipping component, which is connected to the telescopic rod of the flipping cylinder, has an upwardly bent hook portion;

[0019] During the process of the extension rod of the flipping cylinder changing from extension to retraction, the flipping component moves from the feeding end to the discharging end, so that the hook part pushes the ladder lining of the bottom wall of the storage bin to flip.

[0020] According to the technical solutions provided in certain embodiments of this application, the storage bin includes:

[0021] A fixed wall is disposed on the sliding seat;

[0022] The movable wall is detachably connected to the fixed wall to adjust the width of the slide groove so that there is a gap of 3mm-5mm between the slide groove and the ladder liner.

[0023] According to the technical solutions provided in certain embodiments of this application, the conveying device includes:

[0024] A sliding part is disposed on the support platform, and the sliding part reciprocates along the length direction of the support platform;

[0025] A clamping part is disposed on the sliding part, and the clamping part is capable of clamping the ladder liner at the lower part of the storage bin to transport the ladder liner to the welding device.

[0028] Three first adjustment components are provided, each of which is disposed on the first support column. Each first adjustment component includes two first adjustable stroke cylinders and one first telescopic cylinder. The first telescopic cylinder extends and retracts along the length direction of the support platform, and the two first adjustable stroke cylinders extend and retract along the width direction and height direction of the welding equipment, respectively.

[0029] Three welding torches are connected to three first adjustment components respectively. The welding nozzles of the three welding torches correspond to the ends of the three surfaces of the ladder liner and the welding points of the ladder edge respectively. The height of the welding nozzle of the middle welding torch is higher than the height of the welding nozzles of the two adjacent welding torches.

[0030] A detection component is provided on the wire feeding structure of the welding device. The detection component includes a proximity switch and a detection wheel with multiple metal sensors. The detection wheel rotates coaxially with the driven wheel of the wire feeding structure. The proximity switch is positioned corresponding to the detection wheel.

[0031] According to the technical solutions provided in certain embodiments of this application, the cooling device includes:

[0032] trachea;

[0033] An air blowing component is provided at the air outlet of the air pipe, with the air blowing port of the air blowing component facing the weld between the ladder liner and the ladder edge, and the air blowing port of the air blowing component is flat.

[0034] According to the technical solutions provided in certain embodiments of this application, the painting apparatus includes:

[0035] A second support column is disposed on the support platform;

[0036] The second adjustment component is disposed on the second support column. The second adjustment component includes two second adjustable stroke cylinders and one second telescopic cylinder.

[0038] Compared with existing technologies, the beneficial effects of this application are as follows: Two correspondingly arranged storage devices can fix the positions of both ends of the ladder liners, allowing them to be placed parallel to the horizontal plane, i.e., the ladder liners are placed horizontally with their grooves facing the feed end of the welding equipment. Furthermore, the corresponding arrangement of the two storage devices can simultaneously limit the ends of multiple ladder liners, allowing them to be stacked along the height direction, thus enabling the storage of multiple liners at once for convenient processing. Simultaneously, the storage devices can convey multiple ladder liners downwards one by one, reducing manual operation and labor costs. Moreover, the method of conveying multiple ladder liners one by one, i.e., a step-by-step feeding method, allows the welding equipment to weld multiple ladder liners to the ladder edge one by one, reducing the overall length of the welding equipment and thus minimizing its space occupation. It integrates welding, cooling and painting equipment. After the ladder lining and ladder edge are welded, the welding area can be cooled by blowing air through the cooling device. Then, the welding area can be painted by the painting device to form a coating. The overall welding equipment has a high degree of functional integration and does not need to be moved to other equipment for painting after the ladder lining and ladder edge are welded, thus reducing space occupation.

[0068] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this application.

[0069] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0070] As mentioned in the background section, a ladder-type cable tray is formed by placing two ladder sides parallel to each other, then placing multiple ladder liners at intervals along the length of the two ladder sides, and finally welding the two ends of the multiple ladder liners to the two ladder sides respectively.

[0071] Currently, welding ladder-type cable trays involves manually placing multiple ladder liners into predetermined positions after setting up two ladder sides, followed by welding. This manual placement of each liner is labor-intensive. Current welding equipment operates by first positioning and fixing all liners to the ladder sides, placing multiple lines individually at their designated welding positions, and then welding sequentially. This results in the welding equipment's length being equal to the length of the ladder side of the cable tray. For example, for a 12-meter ladder-type cable tray, the welding area of ​​the equipment needs to be 12 meters long, the feeding end needs to be over 12 meters long, and the discharge end also needs to be 12 meters long, requiring at least 36 meters of space – a very large footprint. Furthermore, the ladder liners are U-shaped or C-shaped cross-section structures with grooves on one side, requiring each of the three sides of one end of the liner to be welded to the inner wall of the ladder side, making manual operation complex. In addition, after the ladder edge and the ladder lining are welded, painting is required. The current welding equipment for ladder cable trays does not have a painting device, so the welded ladder cable trays need to be painted manually, which increases labor costs.

[0072] To address the problems in the prior art, this embodiment provides a welding device for ladder-type cable trays. The following description, in conjunction with the appendix to the specification, details the following steps. Figures 1-14 The welding equipment for ladder-type cable trays according to embodiments of this application is described in detail.

[0073] like Figure 1 As shown, the welding equipment 1000 has two ends in the length direction. The end for feeding materials into the welding equipment 1000 for processing is the feeding end 800, and the end for outputting the finished product is the discharging end 900.

[0074] like Figure 1 , Figure 2 and Figure 9As shown, the welding equipment 1000 for ladder-type cable trays includes a main frame 100, which includes two support platforms 110 arranged parallel to each other. The two support platforms 110 are arranged in parallel and can be used to place the two ladder sides of the ladder-type cable tray respectively, that is, the two ladder sides are also parallel to each other.

[0075] like Figure 3 , Figure 6 , Figure 8 and Figure 10 As shown, a material storage device 200, a welding device 300, a cooling device 400, and a painting device 500 are sequentially provided at corresponding positions along the length of each of the two support platforms 110. In other words, the two support platforms 110 are arranged in parallel, and each of the two support platforms 110 has a material storage device 200, a welding device 300, a cooling device 400, and a painting device 500 at corresponding positions along its length. Thus, the entire welding equipment 1000 has two corresponding material storage devices 200, two corresponding welding devices 300, two corresponding cooling devices 400, and two corresponding painting devices 500. This allows for the storage of multiple ladder liners, and the welding, cooling, and painting of the ladder liners to both ends of the ladders with the two ladder edges, respectively.

[0076] Furthermore, such as Figure 3 As shown, two storage devices 200 are respectively installed on two support platforms 110, and the positions of the two storage devices 200 are corresponding, and they can abut against both ends of the ladder liner, that is, limit both ends of the ladder liner so that the ladder liner is placed horizontally.

[0077] In other words, the two storage devices 200 are equivalent to two support structures, placing the ladder liners horizontally. This structure allows multiple ladder liners to be stacked and stored parallel to the horizontal plane. That is, multiple ladder liners can be stacked and stored by the two storage devices 200 supporting the two ends of the horizontally placed ladder liners, eliminating the need for multiple refills. The storage devices 200 convey the multiple ladder liners downwards one by one, allowing for sequential welding of each liner to the ladder edge. Compared to placing the ladder edge first and then individually placing the multiple liners in their corresponding positions before welding, this reduces the overall size of the welding equipment 1000 and minimizes space occupation. The welding equipment 1000 for the ladder-type cable tray of this application positions the grooves of the multiple stacked and stored ladder liners towards the feed end 800 of the welding equipment 1000. Compared to stacking multiple ladder liners with their grooves facing downwards, this method avoids the problem of misalignment and difficulty in material unloading caused by the narrow edge of the grooved side of the U-shaped ladder liner when multiple U-shaped ladder liners are stacked. Furthermore, the welding equipment 1000 for ladder-type cable trays of this application is applicable to both U-shaped and C-shaped ladder liners.

[0078] Those skilled in the art will understand that one of the surfaces of the ladder liner is a grooved surface with grooves, and the grooves of multiple ladder liners all face the feed end 800 of the welding equipment 1000. The grooves of the ladder liner facing the feed end 800 of the welding equipment 1000 facilitate the subsequent flipping of the ladder liner to the welding state.

[0079] It should be noted here that the horizontal and vertical planes in this article refer to the conventional understanding of horizontal and vertical planes. The vertical plane is perpendicular to the horizontal plane, which will not be elaborated further.

[0080] According to an embodiment of this application, the welding equipment 1000 for ladder-type cable trays uses two corresponding storage devices 200 to fix the positions of both ends of the ladder liners, allowing the liners to be placed parallel to the horizontal plane, i.e., the liners are placed horizontally, with the grooves of the liners all facing the feed end 800 of the welding equipment 1000. Furthermore, the two storage devices 200, when correspondingly arranged, can simultaneously limit the positions of both ends of multiple ladder liners, allowing multiple liners to be stacked along the height direction, i.e., multiple liners can be stored at once, facilitating processing. Simultaneously, the storage devices 200 can convey multiple liners downwards one by one, reducing manual operation and labor costs. Moreover, the method of conveying multiple liners one by one, i.e., the step-by-step feeding method, allows the welding equipment 1000 to weld multiple liners to the ladder edge one by one, reducing the overall length of the welding equipment 1000, thereby reducing the space occupied by the welding equipment 1000. It integrates a welding device 300, a cooling device 400, and a painting device 500. After the ladder lining and ladder edge are welded, the welding area can be cooled directly by blowing air through the cooling device 400, and then the welding area can be coated by spraying paint through the painting device 500. The overall welding equipment 1000 has a high degree of functional integration, eliminating the need to move to other equipment for painting after the ladder lining and ladder edge are welded, thus reducing space occupation.

[0081] In some embodiments of this application, such as Figure 4 As shown, the welding equipment 1000 for ladder-type cable trays also includes two adjusting platforms 130, which are respectively positioned at corresponding locations on the two supporting platforms 110. Each adjusting platform 130 includes a sliding table 131, a sliding seat 133, and multiple third support columns 132. The multiple third support columns 132 are spaced apart along the length of the supporting platform 110, and each column is perpendicular to the upper surface of the supporting platform 110. The upper ends of each column are connected to the lower surface of the sliding table 131, thereby supporting the sliding table 131. The sliding seat 133 slides in cooperation with the sliding table 131. In this application, three third support columns 132 are used, which are parallel to each other and perpendicular to the supporting platform 110.

[0082] Specifically, such as Figure 4 As shown, the sliding table 131 may have a groove, and the sliding seat 133 reciprocates in the groove along the length of the support platform 110. The sliding seat 133 and the sliding table 131 can be controlled by a screw drive to control the position of the sliding seat 133 on the sliding table 131. The storage device 200 is connected to the sliding seat 133, thereby enabling the sliding seat 133 to drive the overall movement of the storage device 200 to adjust the position of the storage device 200.

[0083] It should be noted that, as will be understood from the following text, such as Figure 5 As shown, the conveying device 600 includes a sliding part 610 and three conveying parts 630. The sliding part 610 and the three conveying parts 630 are all spaced apart along the length of the support platform 110, and the three conveying parts 630 move synchronously with the sliding part 610. Thus, the three conveying parts 630 and the sliding part 610 serve as four structures capable of simultaneously conveying the ladder lining and as points for conveying the ladder lining.

[0084] Therefore, in the actual process of welding ladder liners and ladder edges, when welding multiple ladder liners to ladder edges, the spacing between multiple ladder liners needs to be adjusted according to actual needs.

[0085] For ease of explanation, the four points of one sliding part 610 and three conveying parts 630 are defined sequentially as the first point, the second point, the third point, and the fourth point in the direction from the discharge end 900 to the feed end 800. The fourth point is the location of the storage device 200. When the interval between two adjacent ladder linings of the ladder-type cable tray to be processed is D1, the first point is used as the starting point, and the second point is set to a distance of D1 from the first point. Similarly, the interval between the third point and the second point is also D1, and the interval between the fourth point, i.e., the location of the storage device 200, and the third point is also D1.

[0086] If, according to the processing requirements, the interval between two adjacent ladder linings of the processed ladder-type cable tray needs to be changed to D2, then, taking the first point as the starting point, the second point is set to have an interval of D2 between it and the first point. Similarly, the interval between the third point and the second point is also D2. The fourth point, namely the position of the storage device 200, needs to be adjusted so that the interval between the storage device 200 and the third point is also D2. The position adjustment of the storage device 200 is achieved by moving the sliding table 133 along the sliding seat 131 via a screw drive, thereby driving the storage device 200 to move along the length direction of the support platform 110 to adjust its position.

[0087] In some embodiments of this application, such as Figure 4As shown, the material storage device 200 includes a material storage bin 210, a material discharge cylinder 220, a buffer cylinder 230, and a flipping assembly 240.

[0088] Specifically, the storage bin 210 is perpendicular to the horizontal plane, meaning it is arranged vertically. The side wall of the storage bin 210 has a groove 213 along its height. The ends of multiple ladder liners extend through the groove 213 into the interior of the storage bin 210 and abut against its inner wall. Therefore, the two storage bins 210 of the two storage devices 200 can abut against the ends of the ladder liners to limit their movement. This allows multiple ladder liners to be stacked along the groove 213, all parallel to the horizontal plane and capable of sliding downwards along the groove 213. The grooves of the multiple ladder liners face the feed end 800 of the storage bin 210, facilitating subsequent contact with the flipping assembly 240. A through groove 214 is provided at the bottom of the storage bin 210 to form a flipping area 216 between the lower part of the side wall and the bottom wall 215 of the storage bin 210. Figure 13 As shown, the through groove 214 is an open groove that passes through the lower part of the storage bin 210, so that the lower part of the storage bin 210 forms a support platform that allows the ladder liner to move along the length of the support platform 110 with the bottom wall 215 of the storage bin 210 as a support platform.

[0089] The height of the flipping area 216 is less than the width of the ladder liner. Therefore, when the ladder liner slides from the chute 213 to the bottom wall 215 of the storage bin 210, since the grooved surface of the ladder liner faces the feed end 800, a portion of the ladder liner is located within the chute 213, and another portion is located in the flipping area 216. That is, due to the partial restriction of the chute 213, the ladder liner falls to the bottom wall 215 of the storage bin 210 with its grooved surface facing the feed end 800. Then, by pushing the flipping assembly 240, the ladder liner is flipped so that its grooved surface faces the lower horizontal plane. Furthermore, by providing the through groove 214, the ladder liner can move along the length of the support platform 110 through the through groove 214 on the bottom wall 215 of the storage bin 210. Finally, the ladder liner is conveyed by the conveying device 600, causing it to slide out of the bottom wall 215 of the storage bin 210 and move to the welding position.

[0090] like Figure 4 As shown, the discharge cylinder 220 is disposed on the side wall of the storage bin 210, and the telescopic rod of the discharge cylinder 220 extends through the side wall of the storage bin 210 into the interior of the storage bin 210 to block or detach from the lower part of the ladder liner of the lower part of the storage bin 210.

[0091] For ease of description, when multiple ladder liners are stacked, the bottom ladder liner is defined as the first ladder liner, the ladder liner adjacent to the first ladder liner is defined as the second ladder liner, and correspondingly, the ladder liner adjacent to the second ladder liner is defined as the third ladder liner. The same principle applies to subsequent ladder liners.

[0092] Specifically, multiple ladder liners slide downwards along the chute 213. The first ladder liner slides downwards along the chute 213, and the extension rod of the discharge cylinder 220 extends to form a blockage, preventing the first ladder liner from falling from the lower part of the storage bin 210. When the extension rod of the discharge cylinder 220 retracts, the first ladder liner can continue to fall from the lower part of the storage bin 210. This achieves the sequential conveying of multiple ladder liners.

[0093] like Figure 4 As shown, the buffer cylinder 230 is disposed on the side wall of the storage bin 210. When the telescopic rod of the buffer cylinder 230 extends, it abuts against the groove of the adjacent ladder liner at the bottom of the storage bin 210. In other words, when multiple ladder liners slide downward through the slide groove 213, the first ladder liner abuts against the telescopic rod of the discharge cylinder 220. At this time, the telescopic rod of the buffer cylinder 230 extends and abuts against the groove of the second ladder liner. Furthermore, when the telescopic rod of the discharge cylinder 220 retracts, the second ladder liner and the third ladder liner above it, and other ladder liners, are restricted from moving, while only the first ladder liner continues to fall to the bottom wall 215 of the storage bin 210 because it is released from the limit of the discharge cylinder 220.

[0094] Therefore, by combining the material discharge cylinder 220 and the buffer cylinder 230, the function of conveying multiple ladder liners one by one can be realized. Thus, the conveying of ladder liners does not require manual operation to be carried out one by one. It is achieved through the cooperation of the material discharge cylinder 220 and the buffer cylinder 230, which reduces the difficulty of manual operation and improves efficiency.

[0095] like Figure 4 As shown, the flipping component 240 is disposed on the side wall of the storage bin 210. The flipping component 240 is capable of flipping the ladder liner located on the bottom wall 215 of the storage bin 210 in the flipping area 216 so that the groove of the ladder liner faces downward.

[0096] Specifically, when welding the ladder liner to the ladder edge, the groove of the ladder liner faces downwards. When the ladder liner is stored in the storage bin 210, the groove faces the side wall of the storage bin 210 to facilitate contact between the ladder liner and the telescopic rod of the buffer cylinder 230. The flipping assembly 240 can flip the ladder liner so that the groove faces downwards, thus facilitating subsequent welding between the ladder liner and the ladder edge when the conveying device 600 transports the ladder liner to the welding device 300.

[0097] In some embodiments of this application, such as Figure 4As shown, the tilting assembly 240 includes a tilting cylinder 241 and a tilting member 242. The tilting cylinder 241 is disposed on the side wall of the storage bin 210, and the telescopic rod of the tilting cylinder 241 extends and retracts along the length of the support platform 110. The tilting member 242 is connected to the telescopic rod of the tilting cylinder 241, and the tilting member 242 has an upwardly bent hook portion 2421. Thus, the tilting member 242 can be moved by extending and retracting the telescopic rod of the tilting cylinder 241.

[0098] During the process of the extension rod of the tilting cylinder 241 changing from extension to retraction, the tilting component 242 moves from the feed end 800 toward the discharge end 900, so that the hook part 2421 pushes the ladder lining of the bottom wall 215 of the storage bin 210 to tilt.

[0099] Specifically, when the telescopic rod of the tilting cylinder 241 extends, the distance between the tilting component 242 and the feed end 800 is less than the distance between the ladder liner and the feed end 800. At this time, there can be a gap between the hook part 2421 and the ladder liner. When the telescopic rod of the tilting cylinder 241 retracts, the tilting component 242 abuts against the ladder liner and can tilt the ladder liner. As mentioned above, when the ladder liner falls to the bottom wall 215 of the storage bin 210, part of the ladder liner is located in the chute 213 and the other part is located in the flipping area 216. Therefore, the hook part 2421 abuts against the part of the ladder liner located in the flipping area 216. That is, the upper part of the ladder liner is limited by the chute 213 and the lower part of the ladder liner is located in the flipping area 216. When the hook part 2421 pushes the lower part of the ladder liner, the ladder liner will rotate towards the feed end 800 in the flipping area 216 due to the push of the hook part 2421, thereby flipping the ladder liner from the groove towards the feed end 800 to the groove facing downward.

[0100] In some embodiments of this application, such as Figure 4 , Figure 12 and Figure 14 As shown, the storage bin 210 includes a fixed wall 211 and a movable wall 212. Specifically, as... Figure 4 As shown, the fixed wall 211 is disposed on the sliding seat 133, thereby allowing the position of the storage device 200 to be adjusted along the length of the support platform 110 by sliding the sliding seat 133 along the sliding table 131. The movable wall 212 is detachably connected to the fixed wall 211 to adjust the width of the slide groove 213 so that there is a 3mm-5mm gap between the slide groove 213 and the ladder liner. In other words, the width of the slide groove 213 is greater than the thickness of the ladder liner, i.e., there is a 3mm-5mm gap between the slide groove 213 and the ladder liner. By adjusting the position between the movable wall 212 and the fixed wall 211, the width of the slide groove 213 can be easily adjusted, so that the slide groove 213 can both limit the position of the ladder liner and allow the ladder liner to slide smoothly downwards. This also prevents the ladder liner from sliding between the slide grooves 213 and rubbing against the storage bin 210.

[0101] In some embodiments of this application, such as Figure 13 and Figure 14 As shown, the storage bin 210 also includes a guide plate 217. One end of the guide plate 217 is pivotally mounted to the movable wall 212, and the other end of the guide plate 217 can abut against the ladder liner located on the bottom wall 215 of the storage bin 210. Thus, when the ladder liner is flipped by the flipping assembly 240, the guide plate 217 can abut against the wall surface of the ladder liner facing the discharge end 900. Therefore, when the flipping cylinder 241 pushes the hook part 2421 to flip the ladder liner, the guide plate 217 abuts against the surface of the ladder liner facing the discharge end 900, limiting the movement distance of the ladder liner on the bottom wall 215, so that the conveying device 600 can clamp the ladder liner at a designated position, preventing the ladder liner from deviating from the docking position between the conveying device 600 and the ladder liner under the action of the flipping cylinder 241.

[0102] In some embodiments of this application, such as Figure 4 As shown, the welding equipment 1000 for ladder-type cable trays also includes two conveying devices 600. The two conveying devices 600 are respectively set at corresponding positions of the two support platforms 110. The conveying devices 600 can reciprocate along the length direction of the support platform 110 to convey the lower ladder lining of the storage device 200 to the welding device 300.

[0103] Specifically, the conveying device 600 is located below the storage device 200. When the lower part of the storage device 200 conveys a single ladder liner, the ladder liner can fall from the lower part of the storage device 200. The conveying device 600 can convey the single ladder liner to the welding device 300, where the ladder liner is welded to the ladder edge. After the conveying action is completed, the conveying device 600 returns to its previous position to wait for the next ladder liner to fall from the lower part of the storage device 200 and be conveyed.

[0104] Conveying devices 600 are installed at corresponding positions on both support platforms 110, which can simultaneously clamp both ends of the ladder liner and move synchronously for conveying. This ensures that the relative position of the ladder liner to the ladder edge is highly accurate after the ladder liner is conveyed to the welding device 300. Furthermore, both ends of the ladder liner correspond to the ladder edge, preventing the ladder liner from tilting and affecting the accuracy of subsequent welding.

[0105] Furthermore, such as Figure 4As shown, the conveying device 600 includes a sliding part 610 and a clamping part 620. The sliding part 610 is disposed on the support platform 110, and the clamping part 620 is disposed on the sliding part 610. The sliding part 610 reciprocates along the length of the support platform 110, thereby allowing the clamping part 620 to move synchronously with the sliding part 610. The clamping part 620 can clamp the ladder liner at the bottom of the storage bin 210 to convey the ladder liner to the welding device 300. The conveying device 600 enables multiple ladder liners to be conveyed to the welding position one by one without manual operation, reducing labor costs and improving processing efficiency.

[0106] In some embodiments of this application, the clamping part 620 is a gripper, which is pivotally mounted to the sliding part 610. That is, the gripper can be opened and closed by rotation to grip or release the ladder liner. When the gripper is open, it can be parallel to the horizontal plane, allowing it to move to a position below the ladder liner to be conveyed. When the gripper is closed, it grips the outer periphery of the ladder liner and conveys it. Correspondingly, after the conveying device 600 conveys the ladder liner to the welding device 300, the gripper can open to avoid the ladder liner, thus returning to its initial position.

[0107] In some embodiments of this application, such as Figure 5 As shown, the conveying device 600 also includes three conveying sections 630, which are spaced apart along the length of the support platform 110. All three conveying sections 630 move synchronously with the sliding section 610, and at least one of the three conveying sections 630 can contact the ladder lining that has been welded to the ladder edge. That is, when the sliding section 610 moves towards the feed end 800, the three conveying sections 630 also move synchronously towards the feed end 800. Correspondingly, when the sliding section 610 moves towards the discharge end 900, the three conveying sections 630 also move synchronously towards the discharge end 900. Thus, when the sliding section 610 reciprocates to convey the ladder lining one by one, at least one of the three conveying sections 630 can simultaneously convey the welded portion of the ladder bridge towards the discharge end 900 by contacting the ladder lining that has been welded to the ladder edge, thereby realizing the automatic welding conveying function of the welding equipment 1000.

[0108] In some embodiments of this application, the welding equipment 1000 for ladder-type cable trays further includes a base frame 700. The base frame 700 is provided with a plurality of slide rails 710 that are parallel to each other and extend along the width direction of the base frame 700. The plurality of slide rails 710 are spaced apart along the length direction of the base frame 700. One of the two support platforms 110 is slidably connected to the plurality of slide rails 710.

[0109] Specifically, such as Figures 1-3 , Figure 6 and Figure 10As shown, support platforms 110 are arranged along the length of the base frame 700. One support platform 110 is located on the side of the base frame 700 along its length, and the other support platform 110 is slidably connected to a slide rail 710 of the base frame 700, thereby allowing the position of the support platform 110 connected to the slide rail 710 to be adjusted. Specifically, the distance between the two support platforms 110 in the width direction of the welding equipment 1000 can be adjusted. This allows for adjustment of the width distance between the two material storage devices 200, the two conveying devices 600, the two welding devices 300, the two cooling devices 400, and the two painting devices 500. The support platforms 110 move via the slide rail 710, facilitating operation.

[0110] The width spacing between the two support platforms 110 is adjusted according to the length of the ladder liner. As mentioned earlier, the ladder liner of the welding equipment 1000 for the ladder-type cable tray of this application is placed horizontally. Therefore, by adjusting the width spacing between the two support platforms 110, the two storage devices 200 can respectively abut against both ends of the ladder liner. This enables the storage and transportation of the ladder liner. Thus, when the width distance between the two support platforms 110 is adjusted according to the length of the ladder liner, subsequent welding, cooling, and painting operations can be further performed correspondingly to the welding points between the ladder liner and the ladder edge.

[0111] In some embodiments of this application, such as Figures 1-3 , Figure 6 and Figure 10 As shown, the base frame 700 also includes a power component 730, which is disposed between the support platform 110, which slides in cooperation with the slide rail 710, and the base frame 700, so that the support platform 110 can reciprocate along the slide rail 710.

[0112] Specifically, the power component 730 can provide power for the movement of the support platform 110, enabling the support platform 110 to reciprocate along the slide rail 710, thereby adjusting the distance between the two support platforms 110 for easier operation.

[0113] In some embodiments of this application, the power component 730 is a lead screw. One end of the lead screw is connected to the support platform 110 that slides with the slide rail 710, and the other end of the lead screw is connected to the base frame 700. The support platform 110 and the base frame 700 are connected by a lead screw drive, which allows for easy control of the position of the support platform 110 with high adjustment accuracy.

[0114] Furthermore, a servo motor can be installed on the base frame 700. The output shaft of the servo motor provides power to the rotation of the lead screw. The servo motor's rotation can be automatically controlled by a program set by an external control device. That is, after the width distance between the two support platforms 110 is set by the external control device, the external device controls the rotation of the servo motor, which in turn controls the rotation of the lead screw to adjust the width distance between the two support platforms 110 to the set width. Therefore, the servo motor does not require long-term manual operation; it can be controlled by an external device. At the same time, the rotation control of the servo motor is more precise, down to the millimeter level.

[0115] In some embodiments of this application, such as Figure 5 As shown, the welding device 300 includes a first support column 310, three first adjustment components 320, three welding torches 330, and a detection component 350. The first support column 310 is mounted on the support platform 110. The first support column 310 serves as a support foundation, ensuring the stability of the positions of the first adjustment components 320 and the welding torches 330. All three first adjustment components 320 are mounted on the first support column 310, and the three welding torches 330 are respectively connected to the three first adjustment components 320. That is, one first adjustment component 320 is connected to one welding torch 330, thereby allowing the position of the corresponding welding torch 330 to be adjusted via the first adjustment component 320.

[0116] Furthermore, such as Figure 5 As shown, the first adjustment component 320 includes two first adjustable stroke cylinders 321 and one first telescopic cylinder 322. The first telescopic cylinder 322 extends and retracts along the length of the support platform 110, and the two first adjustable stroke cylinders 321 extend and retract along the width and height directions of the welding equipment 1000, respectively. Therefore, each welding torch 330 is controlled to move by three cylinders, and each welding torch 330 can move in the height, length, and width directions. The adjustable stroke cylinders can be manually adjusted to adjust the extension length of the telescopic rod, thereby fine-tuning the movement distance of the corresponding welding torch 330 and making the movement stroke of the welding torch 330 more precise.

[0117] like Figure 5 As shown, the welding nozzles of the three welding torches 330 correspond to the welding points at the ends of the three surfaces of the ladder liner and the ladder edges, respectively. The welding nozzle of the middle welding torch 330 is higher than the nozzles of the two adjacent welding torches 330. Therefore, the welding nozzles of the three welding torches 330 are distributed in an arc shape in height, corresponding to the welding positions at the ends of the ladder liner and the ladder edges. The three welding torches 330 are positioned at the three welding points, resulting in a more uniform welding effect.

[0118] In other words, such as Figure 5As shown above, one surface of the ladder insert is a grooved surface. When welding the ladder insert to the ladder edge, the grooved surface of the ladder insert faces the downward horizontal plane. The two ends of the grooved surface of the ladder insert are not welded to the ladder edge, but the end edges of the other three surfaces of the ladder insert are welded to the ladder edge. Therefore, the welding nozzles of the three welding guns 330 correspond to the end edges of the three surfaces respectively. The three welding nozzles of the three welding guns 330 are at different heights, with the welding nozzle of the middle welding gun 330 at a higher height than the welding nozzles of the two adjacent welding guns 330. This ensures that the three welding nozzles correspond to the three edges of the ladder insert that need to be welded to the ladder edge.

[0119] Furthermore, the welding of the ladder lining to the ladder edge can be done by drag welding or spot welding.

[0120] In some embodiments of this application, such as Figure 11 As shown, the welding apparatus 300 also includes a detection component 350. The detection component 350 is disposed on the wire feeding structure of the welding apparatus 300. The detection component 350 includes a proximity switch 352 and a detection wheel 351 having multiple metal sensing elements 353. The detection wheel 351 rotates coaxially with the driven wheel of the wire feeding structure. The proximity switch 352 is disposed at a position corresponding to the detection wheel 351.

[0121] Those skilled in the art will understand that welding requires welding wire, and the welding apparatus 300 has a position for placing the welding wire, namely the wire feeding structure mentioned above (not shown in the figure). The wire feeding structure can transport the welding wire to the inner tube of the welding torch 330 and continuously provide conveying power so that the welding wire is delivered from the nozzle of the welding torch 330. The conveying principle of the wire feeding structure is as follows: the wire feeding structure has a driving wheel and a driven wheel, and the wheel surface of the driving wheel can abut against the wheel surface of the driven wheel, that is, the driving wheel and the driven wheel are on the same plane, and the rotation axis of the driving wheel is parallel to the rotation axis of the driven wheel.

[0122] The welding wire is positioned behind the wire feeding structure and passes through the interface between the surfaces of the drive wheel and the driven wheel; in other words, the welding wire is clamped at the interface of the two wheel surfaces. The rotation of the drive wheel provides power for the feeding of the welding wire, thereby gradually feeding the welding wire out of the welding torch 330 for welding. Simultaneously, the driven wheel also rotates synchronously, causing the detection wheel 351, which has multiple metal sensors 353, to rotate coaxially with the driven wheel. The multiple metal sensors 353 are disposed on the surface of the detection wheel 351 facing the proximity switch 352 and are spaced apart around the rotation axis of the detection wheel 351. Thus, when the welding wire can be fed by the welding torch 330 through the clamping of the drive wheel and the driven wheel, the detection wheel 351 rotates. After the detection wheel 351 rotates, the metal sensors 353 react with the proximity switch 352, enabling the proximity switch 352 to send a detection signal.

[0123] Correspondingly, when the welding wire cannot be fed inside the welding gun 330 due to wire blockage, the rotational power of the drive wheel cannot drive the driven wheel to rotate, and the detection wheel 351 cannot rotate either. The proximity switch 352 cannot detect the metal sensor 353 passing through the proximity switch 352 within a predetermined time, which can notify that the wire feeding has failed, thereby enabling the welding equipment 1000 of this application to detect whether wire blockage has occurred.

[0124] For example, if the system is set to require the proximity switch 352 to detect the passage of a metal sensor 353 within a specified time, then the detection wheel 351 will rotate once, and the proximity switch 352 will send a signal when a metal sensor 353 passes by. If the proximity switch 352 fails to react to a metal sensor 353 within the predetermined time, it will not send a signal, and the welding equipment 1000 will indicate that wire blockage has occurred.

[0125] The proximity switch 352 can be installed on the welding device 300 according to actual needs.

[0126] In some embodiments of this application, such as Figure 7 As shown, the cooling device 400 includes an air pipe 410 and an air blowing component 420. The air pipe 410 can be a bendable type, allowing adjustment of the air blowing direction of the air blowing component 420. The air inlet of the air pipe 410 can be connected to an external air supply device. The air blowing component 420 is positioned at the air outlet of the air pipe 410, with its air outlet facing the weld between the ladder lining and the ladder edge. The air outlet of the air blowing component 420 is flat. The flat air outlet allows for a wider range of airflow.

[0127] In some embodiments of this application, such as Figure 7 As shown, the painting device 500 includes a second support column 510, a second adjustment component 520, and a paint gun 530. The second support column 510 is mounted on the support platform 110 and serves as a support base, ensuring the stability of the positions of the second adjustment component 520 and the paint gun 530.

[0128] Furthermore, such as Figure 5As shown, the second adjustment component 520 is mounted on the second support column 510, and the paint gun 530 is mounted on the second adjustment component 520. The paint gun 530 can evenly spray paint onto the welded joint between the ladder lining and the ladder edge. Spraying paint achieves galvanization of the welded joint between the ladder lining and the ladder edge, thus preventing rust. Furthermore, spraying paint can cover the welding marks between the ladder lining and the ladder edge, improving the overall aesthetics. The second adjustment component 520 includes two second adjustable stroke cylinders 521 and one second telescopic cylinder 522. The second telescopic cylinder 522 extends and retracts along the length of the support platform 110, and the two second adjustable stroke cylinders 521 extend and retract along the width and height directions of the welding equipment 1000, respectively. Therefore, the position of the paint gun 530 is controlled by three cylinders, allowing the paint gun 530 to move in the height, length, and width directions. The adjustable stroke cylinder can be manually adjusted to adjust the extension length of the telescopic rod, thereby fine-tuning the travel distance of the paint gun 530 and making the travel stroke of the paint gun 530 more precise.

[0129] In some embodiments of this application, such as Figure 3 , Figure 5 and Figure 6 As shown, the main frame 100 also includes a plurality of longitudinal guide members 111 and a plurality of transverse guide members 112. The plurality of longitudinal guide members 111 are spaced apart along the length direction of the support platform 110 to the upper surface of the support platform 110, and the plurality of transverse guide members 112 are spaced apart along the length direction of the support platform 110 to the opposite walls of the two support platforms 110. The plurality of longitudinal guide members 111 and the plurality of transverse guide members 112 are all bearings.

[0130] Specifically, such as Figure 3 , Figure 5 and Figure 6 As shown, the support platform 110 is equipped with multiple longitudinal guide members 111 and multiple transverse guide members 112. The rotation axis of the longitudinal guide members 111 is perpendicular to the horizontal plane, and the rotation axis of the transverse guide members 112 is perpendicular to the vertical plane. The longitudinal guide members 111 can abut against the outer surface of the ladder edge. The transverse guide members 112 can abut against the lower surface of the ladder edge. Thus, when conveying the ladder edge, the multiple longitudinal guide members 111 and multiple transverse guide members 112 convey the ladder edge, making the conveying of the ladder edge smoother. Furthermore, the multiple longitudinal guide members 111 and multiple transverse guide members 112 are all bearings, which can convey the ladder edge and limit its movement, and can also reduce the wear on the ladder edge during conveying, protecting the surface integrity and aesthetics of the product, and improving the quality of the product.
