Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module construction technology, specifically to a portable cable laying auxiliary device. Background Technology

[0002] During the construction of photovoltaic power generation systems, the main cables are usually laid in cable trenches or cable trays. For cables laid in cable trays, due to their thickness and overall weight, the friction between the cable and the ground is relatively large after the cable is laid on the ground and then moved into the cable tray. This can easily damage the insulation layer on the outer surface of the cable. At the same time, the force required to pull the cable is relatively large, which affects the laying efficiency of the cable.

[0003] The utility model patent with patent number CN218897023U discloses a cable laying guide frame, including a fixing seat for fixing on a cable support, a plurality of vertical rollers on the fixing seat, and a plurality of horizontal rollers on the fixing seat. The fixing seat includes a square sleeve and a plurality of fixing bolts. The fixing bolts are matched with threaded holes on the rear side wall of the square sleeve and pass through the side wall. The vertical rollers are erected at equal intervals on the front side of the top of the square sleeve. The number of horizontal rollers is one less than that of the vertical rollers. The horizontal rollers are located on the top surface of the square sleeve behind the vertical rollers. The top of the horizontal rollers is located below the two adjacent vertical rollers in the front-rear view, and the left and right ends of the horizontal rollers are located below the two adjacent vertical rollers in the front-rear view. By using multiple horizontal rollers for rolling support and positioning a cable between two adjacent vertical rollers, multiple cables can be easily guided at bends, avoiding damage caused by friction with sharp edges at bends. The guide frame can be easily fixed to the cable support via a fixing seat. The guide frame effectively reduces the need for additional manual guides at bends, lowering labor costs and improving construction efficiency. In this patent, the cable laying can be guided, reducing friction between the cable and the ground. However, when placing the cable in the cable tray after laying it out, the retaining bars need to be removed and the cable lifted into the tray, which is cumbersome and inefficient.

[0026] Preferably, the first support column 101 and the second support column 102 are both hollow rectangular rods, and the bottom end of the first support column 101 and the second support column 102 is provided with a support base plate 9.

[0031] In the above setup, the support base plate 9 is supported on the ground, and the fixing rod 2 passes through the fixing hole 12 and is inserted into the ground, so that the support base plate 9 is fixed on the ground. The two sets of support base plates 9 are located on both sides of the cable tray 26, so that the connecting frame 3 is located directly above the cable tray 26. By adjusting the position of the first support column 103, the first support column foot 101, the second support column 104, and the second support column foot, and fixing them with locking columns, the distance between the connecting frame 3 and the cable tray 26 can be adjusted, that is, the height of the connecting frame 3 can be adjusted.

[0032] Further, see Figure 3 Support plates 13 are provided on both sides of the connecting frame 3, and a rotating shaft 14 is provided on the support plate 13. The vertical guide roller 6 is rotatably mounted on the rotating shaft 14.

[0037] Further, see Figure 2 , 5 A locking rod 19 is rotatably mounted on the connecting frame 3, and a limiting rod 20 is provided at the end of the locking rod 19; a locking plate 21 is provided at the end of the support frame 15 away from the first support column 103, and a locking groove 22 is provided on the locking plate 21. One end of the locking rod 19 passes through the locking groove 22. The locking rod 19 rotates under the action of external force, so that the limiting rod 20 rotates accordingly and abuts against the locking plate 21, thereby restricting the position of the locking plate 21.

[0038] Preferably, the connecting frame 3 is provided with a movable hole 23, and one end of the snap-fit ​​rod 19 passes through the movable hole 23 and is provided with a rotating handle 24.

[0040] Furthermore, the outer end face of the horizontal guide roller 7 extends beyond the end face of the support frame 15.

[0041] Preferably, the support frame 15 is a hollow rectangular body, and a connecting shaft 25 is provided on the inner wall of the support frame 15. The two ends of the horizontal guide roller 7 are rotatably connected to the connecting shaft 25.

[0042] In the above configuration, one end of the support frame 15 is rotatably connected to the first column rod. By rotating the locking rod 19, the limiting rod 20 is parallel to the locking groove 22. After the limiting rod 20 disengages from the locking plate 21, the support frame 15 rotates along the rotating shaft 14 to disengage from the locking rod 19, and the horizontal guide roller 7 flips accordingly. At this time, the cable laying groove 5 is fully open, and the cable located in the guide channel 4 moves down into the cable tray 26. When laying a new cable, the support frame 15 is rotated to be parallel to the horizontal plane, the limiting rod 20 passes through the locking groove 22, and the locking rod 19 is rotated to drive the limiting rod 20 to rotate. The limiting rod 20 abuts against the bottom end of the locking plate 21, thereby fixing the position of the support frame 15. At this time, the horizontal guide roller 7 is parallel to the horizontal plane, pulling the cable end through the guide channel 4. The bottom end of the cable is located on the horizontal guide roller 7, and both sides of the cable are restricted by the branch guide roller.

[0043] In this embodiment, when laying the cable, the device is first installed at intervals on the cable tray 26, with support plates on both sides of the cable tray 26 and connecting frame 3 above the cable tray 26. The height of the support frame 1 can be adjusted as needed, thereby adjusting the height of the connecting frame 3. During the initial cable laying, the support frame 15 is kept horizontal by the limiting rod 20 and the locking rod 19. The horizontal guide roller 7 is kept horizontal and forms a "U" shape with the two sets of vertical guide rollers 6. The cable end is passed through the guide channel 4. The horizontal guide roller 7 supports the bottom of the cable, and the vertical guide rollers 6 support both sides of the cable. During the pulling of the cable, the horizontal guide roller 7 rotates accordingly, reducing the electrical current. The friction during cable movement, along with the vertical guide roller 6 acting as a cable limiter; after the cable is laid out, the locking rod 19 is rotated one by one to make the limiting rod 20 parallel to the locking groove 22, the support frame 15 disengages from the limiting rod 20 and flips over, and the cable loses the support of the horizontal guide roller 7 and falls into the cable tray 26, eliminating the need for manual lifting of the cable laid out on the ground and placing it into the cable tray 26; when laying the cable, the downward speed of the cable is manually controlled to prevent the cable from directly hitting the cable tray 26; after one cable is laid out, the support frame 15 is connected to the locking rod 19, so that the horizontal guide roller 7 is reset, and new cables can be laid out.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
