[0001] The present invention relates to the technical field of welding devices, in particular to a special welding device for cable trays. Background Art

[0002] Cable trays are divided into trough-type, tray-type and ladder-type structures, which are fixed by cross arms, installation accessories, etc., and can neatly transfer cables from one device to another. The ladder-type cable tray is composed of two L-shaped plates and several cross tubes. The two L-shaped plates and several cross tubes need to be welded.

[0011] Compared with the prior art, the present invention provides a special welding device for cable trays, which has the following beneficial effects: 1. The special welding device for cable tray inserts the L-shaped plates on both sides of the cable tray to be welded into the two positioning grooves, and then the transverse tubes to be welded can be rolled along the trapezoidal plate b one by one through the trapezoidal plate b, and then the transverse tubes will fall through the slots into each supporting half-tube one by one, and then the two lifting bars can be driven upward by the cylinder to move upward, thereby driving each transverse bar to move upward, thereby driving each supporting half-frame to move upward and moving the transverse tube to be welded upward between the two L-shaped plates, so that the supporting transverse tube can be quickly positioned, so that the robot arm can control the welding gun for welding, and through each set of support bars, the height can be reduced one by one from left to right after the supporting half-tube moves downward to the bottom, so that the layout of each supporting half-tube is consistent with the inclined surface angle of the trapezoidal plate b, so that more than one transverse tube entering each slot or blocking the latter transverse tube from sliding to the right can be avoided.

[0012] 2. The special welding device for the cable tray moves the horizontal tube to be welded upward by supporting the half frame. The horizontal tube will first squeeze the two trapezoidal strips a, and then drive the two long strips to move away from each other. When the horizontal tube moves between the two L-shaped plates, the pressure of the pressure spring will drive the two L-shaped plates to fit with each horizontal tube, thereby preventing the horizontal tube from being unable to position and smoothly enter between the two L-shaped plates and fit with the two L-shaped plates at the same time.

[0013] 3. The cable tray welding device can drive the two back plates to move forward and backward by rotating the two screws back and forth, so that the distance between the two back plates can be adjusted. This makes it convenient for users to adjust the width of the cable tray to be welded.

[0014] 4. The special welding device for the cable tray can facilitate users to rotate the screw back and forth through the rotating disk, and can maintain the stability of the corresponding movable bar through the horizontal tube, so as to stably support the two back plates, and can guide users through the two inclined plates to facilitate users to insert the L-shaped plate.

[0015] 5. The special welding device for the cable tray can position the two trapezoidal bars according to the position of the back plates by adjusting the two back plates, and then each positioning plate can be used to cooperate with each positioning bar to position the two trapezoidal bars according to the position of the back plates. In this way, the fixed rod can be fixed to the long plate, and then the movable bar can be fixed by using the fixed rod to cooperate with the small plate and the fixed plate. In this way, when the supporting half frame moves upward and the horizontal tube that needs to be welded moves upward, it will drive the horizontal tube to move along the inclined surface of the trapezoidal bar to center the horizontal tube.

[0016] 6. The special welding device for the cable tray adjusts its position by moving the trapezoidal bar b. In this way, the two movable plates can be adjusted according to the length of the cross tube to guide the cross tube into the slot. The slide groove and the limit block can be used for positioning to prevent the strip from moving too far due to the pressure of the pressure spring. BRIEF DESCRIPTION OF THE DRAWINGS

Bar 17, each group of support bars 17 is fixedly installed with a horizontal bar 16, and each horizontal bar 16 is fixedly installed with a square tube 19 on the lower side. Each square tube 19 is movably connected with a vertical bar 20, and each vertical bar 20 is fixedly connected to the upper inclined surface of the trapezoidal plate a3. Long bars 9 are provided on the front and rear walls of the fixed half frame 5. Positioning grooves 26 are provided on the left sides of the two long bars 9. Square grooves 34 are provided on the inner walls of the two positioning grooves 26 close to each other. By inserting the L-shaped plates on both sides of the cable tray to be welded into the two positioning grooves 26, the horizontal tubes to be welded can be rolled along the trapezoidal plate b21 one by one through the trapezoidal plate b21, and then the horizontal tubes will fall through the notch 22 one by one into each supporting half pipe 18, and then the two lifting bars can be driven by the cylinder 33. 4 moves upward, thereby driving each horizontal bar 16 to move upward, thereby driving each supporting half frame 18 to move upward and moving the horizontal pipe to be welded upward between the two L-shaped plates, so that the robot arm 12 can control the welding gun to perform the welding process. Through each group of support bars 17, the height of the supporting half pipe 18 can be gradually reduced from left to right after it moves downward to the bottom, so that the layout of each supporting half pipe 18 is consistent with the inclined surface angle of the trapezoidal plate b21, so that more than one horizontal pipe can be prevented from entering each notch 22 or the rear horizontal pipe can be prevented from sliding to the right. The front and rear walls of the two fixed half frames 5 are both provided with back plates 38, and a plurality of pressure springs 25 are fixedly installed on the side away from each other of the two long strips 9. Each pressure spring 25 is respectively connected to the two The two back plates 38 are fixedly connected, and a short column 23 is fixedly installed on the side of each back plate 38 away from each other. A support tube 37 is movably sleeved on each short column 23. Each support tube 37 is fixedly connected to the two long strips 9 respectively. A trapezoidal bar a24 is fixedly installed on the lower side of each long strip 9. When the horizontal tube to be welded is moved upward by supporting the half frame 18, the horizontal tube will first squeeze the two trapezoidal bars a24, and then drive the two long strips 9 to move to the side away from each other. When the horizontal tube moves between the two L-shaped plates, the pressure of the pressure spring will drive the two L-shaped plates to fit with each horizontal tube, thereby preventing the horizontal tube from being unable to position and smoothly enter between the two L-shaped plates and fit with the two L-shaped plates at the same time. The two back plates 38 are fixedly installed on the side away from each other with a movable bar 29.Each movable bar 29 is movable through the front and rear walls of the fixed half frame 5 respectively, and the two back plates 38 are movably connected to each other on one side through a bearing. A screw rod 31 is movably connected to the front and rear walls of the fixed half frame 5 respectively. A short tube 30 is threadedly sleeved on the two screws 31. The two short tubes 30 are fixedly connected to the front and rear sides of the fixed half frame 5 respectively. By rotating the two screws 31 back and forth, the two back plates 38 can be driven to move forward and backward, so that the spacing between the two back plates 38 can be adjusted. This makes it convenient for users to adjust the width of the cable tray to be welded according to their needs. A rotating disk 32 is fixedly installed on the two screws 31. The two long strips 9 The upper side is fixedly installed with an inclined plate 10, and each movable bar 29 is movably sleeved with a transverse tube 27. Each transverse tube 27 is fixedly connected to the front and rear walls of the fixed half frame 5 respectively. The user can rotate the screw 31 back and forth conveniently through the rotating disk 32. The corresponding movable bar 29 can be kept stable through the transverse tube 27, so that the two back plates 38 can be stably supported. The two inclined plates 10 can be used to guide the user to insert the L-shaped plate. A positioning bar 28 is fixedly installed on each movable bar 29. Several movable bars 13 are movably penetrated on the fixed half frame 5. The front and rear inner walls of the fixed half frame 5 are fitted with two trapezoidal bars 8. The front and rear sides of the fixed half frame 5 are set There are fixing rods 11, two fixing rods 11 are respectively arranged above each moving bar 13, a small plate 15 is fixedly installed on the upper side of each moving bar 13, and a long plate 7 is fixedly installed on both sides of the fixed half frame 5. A positioning plate 14 is fixedly installed on each moving bar 13. After adjusting the two back plates 38, the two trapezoidal bars 8 can be positioned according to the position of the back plate 38 by each positioning plate 14 in conjunction with each positioning bar 28. In this way, the fixing rods 11 can be fixed to the long plate 7, and then the fixing rods 11 are used to cooperate with the small plate 15 and the fixing plate 14 to fix the moving bar 13. In this way, when the support half frame 18 moves upward, the horizontal pipe that needs to be welded moves upward. This will drive the cross tube to move along the inclined surface of the trapezoidal bar 8 so that the cross tube is centered. The lower sides of the two trapezoidal bars b8 are fixedly installed with movable plates 6. The lower sides of the two movable plates 6 are in contact with the upper inclined surface of the trapezoidal plate b21. Each support tube 37 has two chute grooves 35, and each chute 35 is movably connected to a limit block 36. Each limit block 36 is fixedly connected to each short column 23. The position is adjusted by moving the trapezoidal bar b8. In this way, the two movable plates 6 can be adjusted according to the length of the cross tube to guide the cross tube into the slot 22. The chute 35 and the limit block 36 can be used for positioning to prevent the production strip 9 from moving too far due to the pressure of the pressure spring.

[0022] When in use, the first step is: insert the L-shaped plates on both sides of the cable tray to be welded into the two positioning grooves 26, and then the transverse tubes to be welded can be rolled along the trapezoidal plate b21 one by one through the trapezoidal plate b21, and then the transverse tubes will fall through the notches 22 one by one into each supporting half-tube 18, and then the two lifting bars 4 can be driven upward by the cylinder 33, thereby driving each transverse bar 16 to move upward, thereby driving each supporting half-frame 18 to move upward and move the transverse tube to be welded upward between the two L-shaped plates, so that the robot arm 12 can control the welding gun to perform welding processing, and through each group of support bars 17, the height can be gradually reduced from left to right after the supporting half-tube 18 moves downward to the bottom, so that the layout of each supporting half-tube 18 is consistent with the inclined surface angle of the trapezoidal plate b21, so that more than one transverse tube entering each notch 22 or blocking the latter transverse tube from sliding to the right can be avoided.

[0023] Step 2: When the cross tube to be welded is moved upward by supporting the half frame 18, the cross tube will first squeeze the two trapezoidal strips a24, and then drive the two long strips 9 to move away from each other. When the cross tube moves between the two L-shaped plates, the pressure of the pressure spring will drive the two L-shaped plates to fit with each cross tube, thereby preventing the cross tube from being unable to position and smoothly enter between the two L-shaped plates and fit with the two L-shaped plates at the same time.

[0024] Step 3: By rotating the two screws 31 back and forth, the two back plates 38 can be driven to move forward and backward, so that the distance between the two back plates 38 can be adjusted, so that the user can adjust the width of the cable tray according to the needs of welding.

[0025] Step 4: The rotating disk 32 can facilitate the user to rotate the screw 31 back and forth, and the horizontal tube 27 can maintain the stability of the corresponding movable bar 29, thereby stably supporting the two back panels 38. The two inclined plates 10 can guide the user to facilitate the user to insert the L-shaped plate.

[0026] Step 5: After adjusting the two back plates 38, each positioning plate 14 can be used to cooperate with each positioning bar 28 to position the two trapezoidal bars 8 according to the position of the back plates 38, so that the fixing rod 11 can be fixed to the long plate 7, and then the fixing rod 11 is used to cooperate with the small plate 15 and the fixing plate 14 to fix the movable bar 13. In this way, when the support half frame 18 moves upward and the cross tube that needs to be welded moves upward, it will drive the cross tube to move along the inclined surface of the trapezoidal bar 8 to center the cross tube.

[0027] Step 6: Adjust the position by moving the trapezoidal bar b8, so as to adjust the two movable plates 6 so that the guide cross tube can be adjusted according to the length of the cross tube to enter the slot 22. The slide groove 35 and the limit block 36 can be used for positioning to prevent the production strip 9 from moving too far due to the pressure of the pressure spring.
