Description

[0001] The present invention relates to the technical field of cable tray welding processing, and particularly relates to a segmented cable tray staggered-layer overlapping welding device. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, arms and installation accessories, etc. The cable trays in buildings can be erected independently or laid on various building and pipe gallery brackets. The grid type cable tray mainly consists of keels, end ornaments, cross ornaments and cover plates, etc. The keels are usually welded and connected by the overlapping welding method, and then the components such as end ornaments, cross ornaments and cover plates are assembled.

[0003] In the prior art, when the cable grid type tray is welded and assembled, the warp wires and weft wires are arranged in a laminated and staggered manner for welding. The warp wires are continuously fed manually through threading, while the weft wires are intermittently fed by relevant equipment to initially form a grid form, and then the connection points are welded one by one synchronously. However, when the warp wires and weft wires are welded synchronously, it is difficult for the weft wires to form a stable position during the continuous feeding of the warp wires, that is, the weft wires will roll forward and backward or even skew after being positioned, resulting in welding deviation and a decrease in the yield of the finished product. Therefore, the present application proposes a solution. Summary of the Invention

A blanking straight groove is installed at the lower end of the feeding box corresponding to the transverse falling hole; In front of the lower end of the blanking straight groove, a welding seat aligned with the intersection of the warp wires and weft wires is rotatably installed, a welding rod is installed at the lower end of the welding seat, and an electromagnetic adsorption rod is installed at the lower end of the base plate corresponding to the welding rod.

[0006] Further set as: a cylinder is installed at the middle position of the bottom of the feeding box, the output end of the cylinder is horizontally installed with a fixing plate, and the upper end of the fixing plate is connected to the bottoms of a plurality of the lifting rod seats.

[0007] Further set as: guide plates are symmetrically installed on both sides of the bottom of the feeding box, guide holes are formed on both sides of the guide plates, guide rods matching the guide holes are installed at both ends of the fixing plate, and the lifting rod seats reciprocate along the running tracks of the guide rods in the guide holes.

[0008] Further set as: rod grooves are formed on both the intermittent stepping rod seat and the lifting rod seat, a blanking slope is installed on one side of the feeding box away from the transverse falling hole, and the bottom end of the blanking slope is aligned with one side of the rod groove at the bottom.

[0009] Further set as: a chassis is installed on one side of the substrate, an electric push rod is arranged inside the chassis, and positioning frames are installed on both sides of the substrate corresponding to the overlapping welding forming area.

[0010] Further set as: sliding rods are installed at both ends of the self-driven roller, the outer ends of the sliding rods penetrate through the positioning frames and are connected to the output end of the electric push rod, and the inner ends of the sliding rods are movably connected to sleeves fixedly connected to another positioning frame.

[0013] The present invention has the following beneficial effects: 1. The present invention aims at the problem of welding deviation caused by the difficulty of the weft wire to form a stable landing during the continuous feeding of the warp wire. By combining the synchronous longitudinal feeding of the warp wire with the intermittent merging of the weft wire, a grid structure is formed, and it is ensured that the merging stage of the weft wire and the warp wire is stably landed, achieving the purpose of accurate overlapping welding; 2. During the overlapping welding process, while the preliminary correction feeding of the warp threads is completed, secondary correction feeding can also be performed by the self-driven rollers during the subsequent continuous feeding of the warp threads. Specifically, the warp threads pass through the limiting hoop in the longitudinal feeding cylinder, and after obtaining the preliminary correction feeding, they continue to feed. And the secondary correction feeding can be completed under the supporting action of the movably arranged self-driven rollers. That is, during the continuous feeding of the warp threads, when the warp threads deviate at the un-welded intersection points, the deviation correction action is immediately carried out, so as to complete the double smooth correction feeding actions in combination with the preliminary correction feeding of the warp threads, ensuring the accuracy during the continuous feeding of the warp threads and avoiding the deviation phenomenon that occurs when stacking with the weft threads. 3. During the overlapping welding operation stage, the welding rod will generate high temperature. To avoid the influence of the high temperature of the welding rod, during the welding gap, that is, the feeding stage of the warp threads, the welding rod follows the welding seat to move away from the intersection point of the two, so as to avoid the high temperature of the welding gap from affecting the bending degrees of the warp threads and the weft threads.

Specific embodiments

[0017] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: Aiming at the problem that it is difficult for the weft thread to form a stable landing position during the continuous feeding of the warp thread, which leads to welding deviation, the following technical solutions are proposed: Referring to Figures 1-8 As shown, a segmented cable tray staggered layer welding device in this embodiment includes a substrate 1. On one side of the upper end of the substrate 1, a feeding plate 5 for continuously feeding the warp thread 6 is installed. Above the side of the substrate 1 close to the feeding plate 5, a feeding box 3 for intermittently feeding the weft thread 7 is suspended; A longitudinal feeding cylinder 16 is embedded in the feeding plate 5. A limiting hoop 17 is inserted inside the longitudinal feeding cylinder 16. The limiting hoop 17 is movably arranged inside the longitudinal feeding cylinder 16 and can be actively adjusted according to the diameters of the warp and weft threads of the grid cable tray to be overlapped and welded, improving its use adaptability; The lower end of the longitudinal feeding cylinder 16 is provided with an extension section for quickly inserting and continuously feeding the warp thread 6. A number of self-driven rollers 26 for supporting the warp thread 6 are horizontally and movably arranged inside the upper end of the substrate 1. Among them, the self-driven roller 26 is a roller structure with a semi-circular groove embedded with a micro motor, which can drive the warp thread 6 to complete frictional transmission and achieve continuous feeding; Referring to Figure 2 , Figure 3 and Figure 7 As shown, intermittent stepping rod seats 12 are fixedly installed at both ends inside the feeding box 3. Lifting rod seats 13 are installed at intervals in the middle of the feeding box 3. And a transverse blanking hole 21 is opened at one end of the feeding box 3. A blanking straight groove 10 is installed at the lower end of the feeding box 3 corresponding to the transverse blanking hole 21; A cylinder 20 is installed at the middle position of the bottom of the feeding box 3. A fixing plate 28 is horizontally installed at the output end of the cylinder 20. The upper end of the fixing plate 28 is connected to the bottom of a number of lifting rod seats 13. Guide plates 29 are symmetrically installed on both sides of the bottom of the feeding box 3. Guide holes are provided on both sides of the guide plates 29. Guide rods 30 matching the guide holes are installed at both ends of the fixing plate 28. The lifting rod seats 13 reciprocate along the running track of the guide rods 30 in the guide holes. Rod grooves 14 are provided on both the intermittent stepping rod seats 12 and the lifting rod seats 13. A blanking slope 19 is installed on one side of the feeding box 3 away from the horizontal blanking hole 21. The bottom end of the blanking slope 19 is aligned with one side of the rod groove 14 at the bottom; During the feeding process of the weft wire 7, the weft wire 7 slides down through the blanking slope 19 in sequence and is distributed in each rod groove 14. Specifically, the cylinder 20 is started to drive the lifting rod seats 13 to reciprocate up and down. During the reciprocating movement, the weft wire 7 on the intermittent stepping rod seats 12 on both sides can be driven to move into the next rod groove 14, so as to achieve the effect of step feeding. And the weft wire 7 in the last rod groove 14 falls into the blanking straight groove 10 through the horizontal blanking hole 21 and drops onto the continuously feeding warp wire 6 from the blanking straight groove 10; During this process, the feeding process of the weft wire 7 can gradually shift into the rod groove 14 on the intermittent stepping rod seat 12 during the intermittent reciprocating movement of the lifting rod seat 13, and finally complete the blanking by dropping into the blanking straight groove 10 through the horizontal blanking hole 21. The intermittent feeding method can adjust the longitudinal interval between the weft wire 7 and the warp wire 6 by changing the telescopic frequency of the cylinder 20, which is convenient for the adaptive overlapping welding processing of the grid cable tray; Refer to Figure 4 、 Figure 5 and Figure 6 As shown in the figure, a welding seat 24 aligned with the intersection of the warp wire 6 and the weft wire 7 is rotatably installed on the front side of the lower end of the blanking straight groove 10. A welding rod 27 is installed at the lower end of the welding seat 24; an electromagnetic adsorption rod 18 is installed on the substrate 1 corresponding to the lower end of the welding rod 27. A coil is sleeved outside the electromagnetic adsorption rod 18. After the coil is energized, the electromagnetic adsorption rod 18 can generate magnetic suction, and can generate electromagnetic attraction for both the warp wire 6 and the weft wire 7, so as to realize the timely fixation of the position after the weft wire 7 drops onto the warp wire 6 and avoid the deviation of the weft wire 7 causing the overlapping welding deviation phenomenon; It should be supplemented and explained here that: the processing procedure of the cable tray is to weld first and then demagnetize. And even if the cable tray after demagnetization still has the phenomenon of incomplete demagnetization, it does not affect the normal use process of the cable tray. Therefore, it will not be elaborated here too much. Here, those skilled in the art only need to know that the energized electromagnetic adsorption rod 18 can adsorb the warp wire 6 and the weft wire 7 synchronously to assist their stable positioning; Refer to Figures 3-6As shown, drive motors 22 are installed on both sides of the lower end of the blanking straight groove 10. The output end of the drive motor 22 is connected to a rotating rod 23. Welding seats 24 are sleeved on the rotating rod 23 at intervals and are vertically aligned with the warp wires 6 respectively. During the overlapping welding process, the drive motor 22 drives the welding seats 24 to approach and move away from the intersection points between the warp wires 6 and the weft wires 7 in a cyclic manner; The purpose is that: during the overlapping welding operation stage, the welding rod 27 will generate high temperature. In order to avoid the influence of the high temperature of the welding rod 27, during the welding gap, that is, the feeding stage of the warp wire 6, the welding rod 27 follows the welding seat 24 to move away from their intersection point, so as to avoid the influence of the high temperature in the welding gap on the bending degrees of the warp wire 6 and the weft wire 7; The staggered overlapping welding process of the present invention is as follows. First, the steel wire of the warp wire 6 is transformed from the coiled state to the straight rod state through a straightening device in the prior art, and then it passes through the longitudinal feeding cylinder 16 on the feeding plate 5 for continuous feeding. During the process of passing through the longitudinal feeding cylinder 16, preliminary corrected feeding can be obtained; Meanwhile, the weft wire 7 slides down through the blanking slope 19 in sequence and is distributed in each rod groove 14. Specifically, the air cylinder 20 is started to drive the lifting rod seat 13 to move up and down reciprocally. During the reciprocating movement process, the weft wire 7 on the intermittent stepping rod seats 12 on both sides can be driven to move into the next rod groove 14, so as to achieve the effect of step feeding. And the weft wire 7 in the last rod groove 14 falls into the blanking straight groove 10 through the transverse falling hole 21 and drops onto the continuously feeding warp wire 6 from the blanking straight groove 10; At the same time, the electromagnetic coil wound around the electromagnetic adsorption rod 18 is energized to generate magnetism, so as to complete the positioning adsorption of the weft wire 7 falling on the warp wire 6. The drive motor 22 is started to drive the welding seat 24 to deflect to the intersection point of the warp wire 6 and the weft wire 7, and the welding operation is completed through the welding rod 27. Thus, the same group of intersection points between the warp wire 6 and the weft wire 7 complete a single overlapping welding step sequence, and the above steps are repeated to complete the segmented overlapping welding of a single-section grid cable tray; Finally, the segmented cutting is completed through the cutting tool head 15 on the cutting table 2, and the overlapping welding of the next section of the grid cable tray continues; Basic principle: The difference between the overlapping welding method of the grid cable tray in the present invention and that in the prior art lies in that: the grid structure is formed by combining the synchronous longitudinal feeding of the warp wire 6 with the intermittent combination of the weft wire 7, and it is ensured that the combination stage of the weft wire 7 and the warp wire 6 is stably positioned, so as to achieve the purpose of accurate overlapping welding.

[0019] Embodiment 2: For the corrected feeding process of the warp wire 6 in Embodiment 1, a secondary correction structure and a correction process for the stable feeding of the warp wire 6 are further provided, which are specifically as follows: Refer to Figure 2 and Figure 8As shown in the figure, a chassis 8 is installed on one side of a substrate 1. An electric push rod is arranged inside the chassis 8. Positioning frames 11 are installed on both sides of the substrate 1 corresponding to the overlapping welding forming area. Sliding rods 9 are installed at both ends of a self-driven roller 26. The outer ends of the sliding rods 9 penetrate through the positioning frames 11 and are connected to the output ends of the electric push rods. The inner ends of the sliding rods 9 are movably connected to sleeves 25 fixedly connected to another positioning frame 11; It should be noted importantly that during the overlapping welding process, while the preliminary correction feeding of the warp wire 6 is completed, secondary correction feeding can also be performed by the self-driven roller 26 during the continuous feeding process of the subsequent warp wire 6. Specifically, the warp wire 6 passes through the limiting hoop 17 in the longitudinal feeding cylinder 16 to obtain preliminary correction feeding and then continues to feed. And the secondary correction feeding can be completed under the supporting action of the movably arranged self-driven roller 26. The self-driven roller 26 is driven by the electric push rod to move the sliding rod 9 horizontally axially, driving the self-driven roller 26 to move horizontally. That is, during the continuous feeding process of the warp wire 6, when the warp wire 6 deflects at the un-welded intersection point, an immediate deviation correction action is performed, so as to complete a double smooth correction feeding action in combination with the preliminary correction feeding of the warp wire 6, ensuring the accuracy during the continuous feeding process of the warp wire 6 and avoiding deviation phenomena when stacking with the weft wire 7; Regarding the above-mentioned immediate deviation correction action when the warp wire 6 deflects at the un-welded intersection point, the deflection of the warp wire 6 is measured by an infrared sensor arranged above, and the left and right deviations are judged according to the infrared sensor, so as to send a signal to the electric push rod, and the electric push rod then performs the corresponding deviation correction action to realize the correction feeding of the warp wire 6; A cutting table 2 is installed on one side of the upper end of the substrate 1. A connecting plate 4 welded to the cutting table 2 is installed at the rear side of the feeding box 3. A cutting tool head 15 for segmentally cutting the grid structure is installed at the bottom of the cutting table 2. Referring to Embodiment 1, after the overlapping welding of the grid cable tray is completed, according to the segment length, the welded cable tray is cut and separated by the cutting tool head 15 on the cutting table 2, and thus is discharged and stacked for collection under the continuous rotation of the self-driven roller 26. Thus, the single processing process of the segmented cable tray is completed.

[0020] Embodiment 3: This embodiment combines the technical contents of Embodiment 1 and Embodiment 2 to form the following overlapping welding method, including the following steps: Step 1: The warp wire 6 first changes the steel wire from the coiled state to the straight rod state through a straightening device, and then continuously feeds through the longitudinal feeding cylinder 16 and the limiting hoop 17 on the feeding plate 5, and preliminary correction feeding can be obtained during the process of passing through the longitudinal feeding cylinder 16; Step 2: The weft wires 7 slide down successively through the blanking slope 19 until they are distributed in each rod groove 14. The air cylinder 20 is activated to drive the lifting rod seat 13 to move up and down reciprocally. During the reciprocating movement, the weft wires 7 on the intermittent stepping rod seats 12 on both sides can be driven to move into the next rod groove 14, so as to achieve the effect of step feeding. And the weft wires 7 in the last rod groove 14 fall into the blanking straight groove 10 through the horizontal through holes 21 and fall onto the continuously feeding warp wires 6 from the blanking straight groove 10; Step 3: When the weft wires 7 contact the warp wires 6, the electromagnetic coils wound around the electromagnetic adsorption rods 18 are energized to generate magnetism, so as to complete the positioning and adsorption of the weft wires 7 falling on the warp wires 6. The driving motor 22 is activated to drive the welding seat 24 to deflect to the intersection of the warp wires 6 and the weft wires 7, and the welding operation is completed through the welding rod 27. Thus, the single overlapping welding sequence of the same group of intersection points between the warp wires 6 and the weft wires 7 is completed; Step 4: The grid-type cable tray is segmented and cut through the cutting tool head 15 on the cutting table 2, and the overlapping welding of the next section of the grid-type cable tray continues.

[0021] The effects of the solution are as follows: In the present invention, the grid structure is formed by combining the synchronous longitudinal feeding of the warp wires 6 with the intermittent merging of the weft wires 7, and it is ensured that the merging stage of the weft wires 7 and the warp wires 6 is stably positioned, so as to achieve the purpose of accurate overlapping welding.

[0022] On the one hand, through the synchronous application of the preliminary correction feeding and the secondary correction feeding for the continuous feeding process of the warp wires 6, the feeding process of the warp wires 6 can stably and parallelly feed and form an absolutely perpendicular state with the weft wires 7; On the other hand, through the intermittent step feeding process during the blanking process of the weft wires 7 combined with the electromagnetic adsorption stage, the accurate positioning of the weft wires 7 after blanking is realized. And after the positioning, the situation that the bending degrees of the warp wires 6 and the weft wires 7 are interfered by the high temperature of the welding gap is avoided through the cyclic overlapping welding approach and separation operation; Combining the two can realize that the weft wires 7 can be relatively and stably positioned and accurately positioned relative to the warp wires during the overlapping welding process of the grid-type cable tray, and avoid the problem of the decrease in the yield of the finished product caused by deviation during overlapping welding.
