Description

Technical Field

[0001] The utility model relates to the field of cable laying, in particular to a cable laying tool. Background Art

[0002] Cable laying is a basic and critical engineering activity in power systems, communication networks, and various industrial and construction fields. The quality of cable laying is directly related to the reliability, safety, and subsequent maintenance costs of the entire system. In order to improve the efficiency and quality of cable laying, various cable laying tools have emerged and are constantly improving with the development of technology.

[0003] At present, most long-distance cables are laid underground. Underground cables require digging cable trenches of a certain depth. Due to terrain or other restrictions, the cable trenches are not straight and often have corners. When encountering corners, the laying of cables also needs to follow the cable trench, so the cables will also change direction. When the cables encounter the corners of the cable trench, since most of the cables are laid by pulling, the cables and the corners of the cable trench will rub against each other for a long time, which can easily cause damage to the cable sheath and also cause the protective layer at the corners of the cable trench to rupture. Utility Model Content

[0004] The utility model is based on the above technical problems and proposes a cable laying tool.

[0005] A cable laying tool, characterized in that it includes: a fixed frame, a rotating shaft, and a roller. The fixed frame is composed of a long rod and two right-angle rods. The long rod is connected to one end of the two right-angle rods, and the angle between the two right-angle rods is not greater than 90°. The right-angle rods are provided with pin holes, and the fixed frame is fixed at the corner of the cable trench by inserting pins into the pin holes. The center lines between the right-angle rods are coaxial; the two fixed frames are arranged opposite each other up and down, and a plurality of rotating shafts are rotatably installed between the two long rods. The rotating shaft is provided with a roller, and the roller is a pulley with a central groove. An arc-shaped sealing plate is also installed on one side of the roller.

[0006] Preferably, the rotating shafts are evenly distributed along the axis of the long rod, and the rotating shafts are provided with the rollers which are evenly distributed.

[0007] Preferably, a fixing hole is opened on the long rod at the lower part, and the long rod is fixed on the ground of the cable trench by the cooperation between the long nail and the fixing hole.

[0008] Preferably, on the roller, the upper and lower sides of the groove are annular edges, and annular grooves are opened on both sides of the annular edges. A group of clips are respectively provided at the upper and lower ends of the inner side of the sealing plate, and the clips are composed of two parallel convex edges. A clip strip corresponding to the annular groove is also provided on the convex edge.

[0009] Preferably, the sealing plate is made of corrosion-resistant plastic.

[0010] Beneficial effect: The tool uses rollers at the corners of the cable trench to avoid direct contact between the cable and the cable trench, and the cable is stuck in the groove in the middle of the roller and restricted by a sealing plate, so that it can be pulled in layers, speeding up the construction progress.

[0013] Figure 3 The utility model shows a structural schematic diagram of the sealing plate. DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] like Figure 1~Figure 3 A cable laying tool is shown, characterized in that it includes: a fixing frame 1, a rotating shaft 8, and a roller 9. The fixing frame 1 is composed of a long rod 2 and two right-angle rods 3. The long rod 2 is connected to one end of the two right-angle rods 3, and the angle between the two right-angle rods 3 is not greater than 90°. In practical applications, the right-angle rods 3 are tightly attached to the side wall 6 of the corner of the cable trench, so the two right-angle rods 3 are generally set to 90° according to the angle of the corner of the cable trench. A pin hole 4 is provided on the right-angle rod 3, and the fixing frame 1 is fixed to the corner of the cable trench by inserting a pin 5 into the pin hole 4. A fixing hole is opened on the lower long rod 2, and the long rod 2 is fixed to the ground of the cable trench by the cooperation of a long nail 12 and the fixing hole.

[0016] The center lines between the right-angle rods 3 and the right-angle rods 3 are coaxial; two fixed frames 1 are arranged opposite to each other up and down, and a plurality of rotating shafts 8 are rotatably installed between the two long rods 2. Rollers 9 are arranged on the rotating shafts 8, and the rollers 9 are pulleys with a central groove 7. The rotating shafts 8 are evenly distributed along the axis of the long rods 2, and rollers 9 are equidistantly distributed on the rotating shafts 8. An arc-shaped sealing plate 10 is also installed on one side of the roller 9, and the sealing plate 10 is made of corrosion-resistant plastic.

[0017] The sealing plate 10 can prevent the bypassed cables from slipping out of the groove 7 of the roller 9 due to loose pulling, resulting in intertwining of the upper and lower cables and affecting normal pulling and wiring.

[0018] In order to make the sealing plate 10 more firmly clamped on the roller 9, the upper and lower sides of the groove 7 of the roller 9 are ring edges, and annular grooves 11 are opened on both sides of the ring edges. A group of clips are respectively provided at the upper and lower ends of the inner side of the sealing plate 10, and the clips are composed of two parallel convex edges 101. A clamping strip 102 corresponding to the annular groove 11 is also provided on the convex edge 101. When the sealing plate 10 is installed, the ring edge is clamped between the convex edges 101, and the clamping strip 102 on the convex edge 101 will be clamped into the annular groove 11.

[0019] In order to improve the adaptability of the sealing plate 10 , it is set to be an arc shape that fits the side of the roller 9 , and an annular groove 11 is provided on the roller 9 , so that the sealing plate 10 can be stuck in any suitable position on the side of the roller 9 .

[0020] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
