Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge welding device. Background Art

[0002] A cable tray is a metal structure used to support the laying of cables, either inside a building or in an outdoor environment. The main function of a cable tray is to provide a safe and orderly passage to enable the transmission of cables from one point to another while protecting the cables from mechanical damage and environmental influences.

[0003] For laying cables of different types or purposes, it is usually necessary to weld separators inside the cable tray. The separators can be used to disperse the load and prevent interference between cables, and also increase the structural strength and stability of the tray.

[0004] At present, existing manufacturers usually weld the partition plates into the cable tray manually, which requires the staff to hold the partition plates by hand while welding the partition plates into the cable tray through a welding machine. Since the specification length of the cable tray is generally two meters or more, the partition plates are long and thin. During welding, the manual welding method makes the partition plates prone to tilting or bending, so that the partition plates cannot divide the interior of the cable tray evenly along its length, resulting in a large error, which affects the quality of the cable tray. Utility Model Content

[0005] In order to solve the technical problems existing in the above background technology, the utility model provides a cable tray welding device.

[0006] The technical solution of this utility model is as follows:

[0007] A cable tray welding device includes a welding platform, the upper end surface of which is provided with staggered transverse grooves and longitudinal grooves, support frames are symmetrically provided on both sides of the cable tray in the width direction, the lower portion of the support frame is inserted into the intersection of the transverse grooves and the longitudinal grooves, the support frame includes vertically arranged support rods, the upper portions of the support rods of two groups of support rods are connected by a transverse connecting rod, the transverse connecting rod is located above the cable tray, a correction plate is rotatably connected to the transverse connecting rod, the correction plate can move along the length direction of the transverse connecting rod, and the correction plate is connected to the transverse connecting rod by a locking member;

[0008] The cable bridge has a partition plate, the length direction of the correction plate is perpendicular to the horizontally arranged transverse connecting rod, and a correction opening capable of passing the partition plate is opened in the middle of the correction plate along its length direction.

[0009] The cable tray is placed along the length of the welding platform so that the cable bridge is located between the two sets of support frames. Before welding the partition plate to the cable tray, first move the correction plate to directly above the partition plate, rotate the correction plate so that the partition plate is located in the correction opening, and lock the position of the correction plate with the locking piece. The correction plate can vertically support the partition plate in the preset welding position. Compared with manually holding the partition plate, the welding error of the partition plate can be greatly reduced.

[0010] The specific structure of the above-mentioned correction plate is that the length of the correction plate is greater than the height of the partition plate, and the lowest point that its lower end can reach is located at the lower part of the partition plate. The correction plate has a certain length and can better support and position the partition plate from top to bottom.

[0011] Regarding the structure of the support frame, the support frame also includes a transverse support plate, whose length direction is consistent with the length direction of the cable tray, and a sliding groove is provided on its upper end face along the length direction. The lower end of the support rod slides in the sliding groove, and its lower part is plugged into the welding platform through a plug-in block. The position of the correction plate can be adjusted by sliding the support rod, thereby realizing the movement of the correction plate while welding the partition plate to the cable tray, without the need to frequently adjust the position of the support frame on the welding platform.

[0012] The above-mentioned plug-in blocks are arranged in such a manner that there are at least two plug-in blocks arranged along the length direction of the transverse support plate, and the plug-in blocks are plugged into the intersection of the transverse groove and the longitudinal groove.

[0013] Regarding the specific structure of the plug-in block, the plug-in block is a cross-shaped plug-in block, which is directly plugged into the welding platform for easy disassembly, and its height is less than the depth of the transverse groove or the longitudinal groove, so that the bottom surface of the plug-in block is higher than the bottom surface of the transverse groove or the longitudinal groove, which can avoid the bottom surface of the plug-in block from colliding with the welding slag or impurities in the transverse groove or the longitudinal groove, affecting the stability of the plug-in block on the welding platform.

[0014] The specific structure of the above-mentioned correction opening is that the width of the correction opening is 1-5 mm greater than the thickness of the partition plate, and an oblique opening is provided at the lower end of the correction opening. The maximum width of the oblique opening is greater than the width of the correction opening. The oblique opening plays a guiding role, facilitating the smooth connection between the correction plate and the partition plate.

[0015] Regarding the connection structure between the correction plate and the transverse connecting rod, the upper end of the correction plate is slidably connected to the transverse connecting rod through a sleeve, and one end of the locking piece passes through the sleeve and is pressed against the outer surface of the transverse connecting rod.

[0016] The partition plates are usually long. In order to facilitate the support and fixation of the partition plates before welding, facilitate welding and improve the quality of the cable tray, multiple groups of support frames are symmetrically arranged. Correction plates are set on each group of symmetrical support frames. Multiple groups of symmetrical support frames are arranged side by side and along the length direction of the cable tray.

[0017] The beneficial effects of the present invention are:

[0018] The transverse connecting rod is arranged parallel to the upper end surface of the welding platform. The correction plate arranged thereon can rotate and move. The correction plate moves to the top of the partition plate and is rotated so that the partition plate is inserted into the correction opening. The correction opening limits the partition plate. The correction plate can be set vertically or tilted, and both can limit the partition plate. The position of the correction plate is fixed by a locking piece, and the direction of the partition plate is welded.

[0019] By moving the position of the support rod on the horizontal support plate, the position of the correction plate on the partition plate can be adjusted, which facilitates welding of the partition plate after the correction position;

[0020] By setting up multiple sets of support frames and correction plates on both sides of the cable tray, the partition plates can be supported and positioned in advance before welding, which facilitates the rapid welding of the partition plates, improves the welding quality of the cable tray, and reduces errors in the partition plates.

[0030] See also Figure 1 、 Figure 2 and Figure 3As shown, a cable tray welding device includes a welding platform 1, whose upper end face is provided with staggered transverse grooves 101 and longitudinal grooves 102, and the cable tray 2 is symmetrically provided with support frames on both sides along the width direction, and the lower part of the support frame is inserted into the intersection of the transverse grooves 101 and the longitudinal grooves 102.

[0031] Among them, the support frame includes a vertically arranged support rod 3 and a horizontally arranged transverse support plate 4. The transverse support plate 4 is arranged above the welding platform 1. The length direction of the transverse support plate 4 is consistent with the length direction of the cable tray 2. Its upper end face is provided with a sliding groove 401 along the length direction. The sliding groove 401 is an inverted T-shaped groove. The lower end of the support rod 3 slides in the sliding groove 401, and the lower end of the support rod 3 is adapted to the sliding groove 401.

[0032] See also Figure 3 and Figure 6 As shown, the lower portion of the transverse support plate 4 is connected to the welding platform 1 via a plug-in block 7. There are at least two plug-in blocks 7, which are arranged along the length of the transverse support plate 4. The plug-in blocks 7 are plugged into the intersection of the transverse groove 101 and the longitudinal groove 102. The plug-in block 7 is a cross-shaped plug-in block 7. The plug-in block 7 is directly plugged into the welding platform 1 for easy disassembly. Its height is less than the depth of the transverse groove 101 or the longitudinal groove 102, so that the bottom surface of the plug-in block 7 is higher than the bottom surface of the transverse groove 101 or the longitudinal groove 102. This can prevent the bottom surface of the plug-in block 7 from colliding with welding slag or impurities in the transverse groove 101 or the longitudinal groove 102, which would affect the stability of the plug-in block 7 on the welding platform 1.

[0033] See also Figure 3 and Figure 5 As shown, the upper portions of the support rods 3 of the two sets of support frames are connected by a transverse connecting rod 5, which is located above the cable tray 2. A correction plate 6 is rotatably connected to the transverse connecting rod 5. The correction plate 6 can move along the length of the transverse connecting rod 5 and is connected to the transverse connecting rod 5 via a locking member 8. Regarding the connection structure between the correction plate 6 and the transverse connecting rod 5, the upper end of the correction plate 6 slides with the transverse connecting rod 5 through a sleeve 9. One end of the locking member 8 passes through the sleeve 9 and is tightened against the outer surface of the transverse connecting rod 5. The locking member 8 is a fastening bolt, and the sleeve 9 is provided with a threaded hole adapted to the fastening bolt.

[0034] See also Figure 3 and Figure 4As shown, the cable tray 2 has a partition plate 201. The length direction of the correction plate 6 is perpendicular to the horizontally arranged transverse connecting rod 5. A correction opening 601 is opened in the middle of the correction plate 6 along its length, through which the partition plate 201 can be inserted. The correction opening 601 is set along the width direction of the correction plate 6, and the end of the correction opening 601 away from the transverse connecting rod 5 is also set as an opening. The specific structure of the above-mentioned correction opening 601 is that the width of the correction opening 601 is 1-5 mm greater than the thickness of the partition plate 201. The length of the correction plate 6 is greater than the height of the partition plate 201, and the lowest point that its lower end can reach is located below the partition plate 201. The correction plate 6 has a certain length to provide good support and positioning for the partition plate 201 from top to bottom.

[0035] The function of the above structure is that before the partition plate 201 is welded to the cable tray 2, the correction plate 6 is first moved to the top of the partition plate 201, and the correction plate 6 is rotated so that the partition plate 201 is located in the correction opening 601. The position of the correction plate 6 is locked by the locking member 8. The correction plate 6 can vertically support the partition plate 201 in the preset welding position. Compared with manually holding the partition plate 201, the welding error of the partition plate 201 can be greatly reduced.

[0036] See also Figure 1 As shown, since the partition plate 201 is usually long, generally at least greater than 2 meters, in order to facilitate the support and fixation of the partition plate 201 in advance before welding, facilitate welding and improve the quality of the cable tray 2, multiple groups of support frames are symmetrically arranged, and each group of two symmetrically arranged support frames is provided with a correction plate 6. Multiple groups of symmetrically arranged support frames are arranged side by side and arranged along the length direction of the cable tray 2. The partition plate 201 is inserted into the correction opening 601 of multiple correction plates 6, which can facilitate the welding of the partition plate 201. A scale can be set on the horizontal connecting rod 5 to facilitate the unified setting of the position of the correction plate 6 to avoid the phenomenon that multiple correction plates 6 are not in the same horizontal plane.
