Description

Technical Field

[0001] This invention belongs to the field of wire laying frame technology, specifically a gantry wire laying device. Background Technology

[0002] Cables are essential power transmission tools in the power industry, mainly used for controlling and installing equipment, as well as for transmitting electricity. In daily life, overhead lines and underground cables in the power field, optical fibers and cables in the information transmission field, and signal lines and control lines in the instrumentation field are all major applications of cables.

[0003] During cable manufacturing, a sheath is typically wrapped around the cable. The cable sheath is the outermost layer of the cable; a common example is the VV cable, which has PVC insulation and a PVC sheath. For different cable models, the material and structure of the sheath may vary to meet different operating environments and performance requirements. For instance, some cables may need to operate in high or low temperature environments, so their sheaths need to be resistant to these conditions. Furthermore, the sheath also protects the internal conductors of the cable from mechanical damage, chemical corrosion, and animal bites.

[0004] When wrapping cables with sheaths, it is usually necessary to move the take-up roller with the cable wound around it to the processing position, and then pull the cable to drive the take-up roller to rotate. During the process of pulling the cable, the cable sheath is wrapped. However, because the take-up roller is heavy after being wrapped with the cable, it is inconvenient to move the take-up roller.

[0005] Therefore, the present invention provides a gantry cable laying device. Summary of the Invention

[0010] Preferably, air guide holes are provided between the multiple sliding frames; the air guide holes are located on the side of the sliding frame away from the guide holes; this makes the anti-wear rollers push the cable more effectively.

[0011] Preferably, an anti-detachment block is fixedly connected to the side wall of the sliding frame; the anti-detachment block is slidably connected to the inside of the first guide frame; this can effectively prevent the sliding frame from detaching from the first guide frame.

[0012] Preferably, a plurality of guide blocks are fixedly connected to the side wall of the sliding rod; the guide blocks are slidably connected to the inside of the movable frame; making the sliding of the sliding rod more stable.

[0013] Preferably, the first sliding block has multiple pushing blocks slidably connected inside, and the pushing blocks are arranged in a circular array inside the first sliding block; a spring is fixed between the side wall of the pushing block and the inner side wall of the first sliding block; multiple pushing grooves are opened on the rotating shaft of the rotating roller; the pushing blocks and pushing grooves are arranged in a corresponding manner; this can effectively prevent the cable from falling off due to rotation after the winding roller stops rotating.

[0014] Preferably, a positioning rod is fixedly connected inside the mobile frame; the first sliding block is slidably connected to the positioning rod, making the sliding of the first sliding block more stable.

[0015] Preferably, a positioning block is fixedly connected inside the movable frame; the positioning block is set on the rotation axis corresponding to the first guide frame and the second guide frame inside the movable frame; this makes the rotation of the first guide frame and the second guide frame more stable.

[0016] Preferably, multiple balls are provided between the first guide frame, the second guide frame, and the positioning block; the sidewalls of the balls contact the sidewalls of the positioning block; this reduces wear between the first guide frame and the positioning block, as well as between the second guide frame and the positioning block.

During the cable feeding process of the feeding device, the take-up roller can rotate synchronously with the rotating roller, the extrusion roller and the take-up roller, thereby realizing the cable feeding structure design, realizing the function of making cable feeding more convenient, and effectively solving the problem that during the cable pulling process, the sheath of the cable is wrapped, and the weight of the take-up roller after the cable is wrapped is heavy, making it inconvenient to move the take-up roller.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figure 1 , Figure 2 and Figure 5As shown in the embodiment of the present invention, a gantry cable feeding device includes a movable frame 1; multiple drive wheels 2 are installed at the bottom of the movable frame 1; multiple first sliding blocks 3 are slidably connected inside the movable frame 1; a spring is fixedly connected between the bottom of the first sliding block 3 and the inner sidewall of the movable frame 1; the first sliding blocks 3 are symmetrically arranged inside the movable frame 1, and a rotating roller 4 is provided between every two symmetrical first sliding blocks 3; the rotating roller 4 is rotatably connected to the internal position of the first sliding block 3; a second sliding block 5 is provided inside the movable frame 1; a sliding rod 7 is fixedly connected to the top of the second sliding block 5; the sliding rod 7 is slidably connected to the internal position of the movable frame 1; a pressing roller 6 is rotatably connected inside the second sliding block 5; a fixing plate 8 is fixedly connected to the top of the movable frame 1; the fixing plate 8 is set at the position corresponding to the sliding rod 7, and a fixing bolt 9 is threadedly connected inside the fixing plate 8; during operation, when it is necessary to wrap the cable with a sheath, the cable winding roller can be placed on the rotating roller. At the top of roller 4, the first sliding block 3 moves downward under the pressure of the take-up roller, and through the push of the spring, the rotating roller 4 is adapted to the bottom side wall of the take-up roller. Then, the second sliding block 5 can be moved, causing the second sliding block 5 to drive the extrusion roller 6 to descend, thereby making the extrusion roller 6 fit against the top side wall of the take-up roller and fix the take-up roller. Then, the fixing bolt 9 can be rotated, so that the fixing bolt 9 engages with the thread of the fixing plate 8, causing the fixing plate 8 to clamp and fix the sliding rod 7, thereby allowing the take-up roller to be stably placed inside the moving frame 1. Then, the drive wheel 2 can be controlled to rotate, driving the moving frame 1 to move. After moving to the processing position, the cable can be passed through the extrusion port of the sheath extruder and wound on the take-up equipment. During the process of the take-up equipment winding the cable, the take-up roller can rotate synchronously with the rotating roller 4, the extrusion roller 6 and the take-up roller, making the take-up roller more stable when unwinding. The rotation of the drive wheel 2 moves the moving frame 1, thereby realizing the unwinding of the cable, making the unwinding of the cable more convenient.

[0033] like Figure 1 and Figure 3As shown, the movable frame 1 has a first wire guide frame 10 and a second wire guide frame 11 rotatably connected inside by a torsion spring; both the first wire guide frame 10 and the second wire guide frame 11 have wire through holes; the first wire guide frame 10 is perpendicular to the rotating roller 4, and the second wire guide frame 11 is inclined; the first wire guide frame 10 has an anti-wear roller 15 inside; the second wire guide frame 11 has a roller installed inside; during operation, when it is necessary to lay the cable, the cable can be passed through the wire through holes of the first wire guide frame 10 and the second wire guide frame 11, thereby allowing... The cable is positioned closer to the center of the movable frame 1, allowing for more accurate insertion into the extrusion port during cable laying. This results in more precise cable laying. Additionally, the presence of anti-wear rollers 15 inside the first conductor frame 10 and rollers inside the second conductor frame 11 reduces friction between the cable and the first and second conductor frames 10 and 11, effectively preventing excessive friction that could damage the cable.

[0034] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a connecting rod 12 is fixedly connected to the top of the first sliding block 3; a push plate 13 is fixedly connected to the top of the connecting rod 12; the push plate 13 is slidably connected to the interior of the movable frame 1; multiple sliding frames 16 are slidably connected inside the first wire frame 10; the sliding frames 16 are positioned at positions corresponding to the wire through holes inside the first wire frame 10; a spring is fixedly connected between the sliding frame 16 and the inner wall of the first wire frame 10; the anti-wear roller 15 is rotatably connected to the interior of the sliding frame 16; the sliding cavity of the push plate 13 and the sliding cavity of the sliding frame 16 are... An air guide pipe 14 is connected between the two parts. During operation, when the rotating roller 4 is squeezed by the winding roller and causes the first sliding block 3 to slide downward, the air pusher plate 13 can be pulled by the connecting rod 12. This allows the air inside the sliding cavity of the air pusher plate 13 to be introduced into the sliding cavity of the sliding frame 16 through the air guide pipe 14, and pushes the sliding frame 16 to slide closer to the wire through hole. This pushes the anti-wear roller 15 to fit with the cable, thereby making the cable more stable inside the wire through hole. At the same time, the connecting rod 12 guides the sliding of the first sliding block 3, making the sliding of the first sliding block 3 more stable.

[0035] like Figure 3As shown, air guide holes 17 are provided between the multiple sliding frames 16; the air guide holes 17 are located on the side of the sliding frame 16 away from the guide holes; during operation, when gas enters the sliding cavity of the sliding frame 16 through the air guide pipe 14, the air between the sliding cavities of each sliding frame 16 can be balanced by providing air guide holes 17, thereby making the distance the sliding frame 16 is pushed out more uniform, so that the cable can be better kept at the center position of the wire through hole of the first wire frame 10, and the anti-wear roller 15 can push the cable better.

[0036] like Figure 3 As shown, an anti-detachment block 18 is fixedly connected to the side wall of the sliding frame 16; the anti-detachment block 18 is slidably connected to the inside of the first guide frame 10; during operation, when the sliding frame 16 slides inside the first guide frame 10, the anti-detachment block 18 on the side wall of the sliding frame 16 can guide the sliding of the sliding frame 16, thereby making the sliding of the sliding frame 16 more stable. At the same time, when the gas pushes the sliding frame 16, the first guide frame 10 blocks the anti-detachment block 18, which can effectively prevent the sliding frame 16 from detaching from the first guide frame 10.

[0037] like Figure 2 As shown, a plurality of guide blocks 19 are fixedly connected to the side wall of the sliding rod 7; the guide blocks 19 are slidably connected to the inside of the movable frame 1; during operation, when the sliding rod 7 slides inside the movable frame 1, the sliding of the sliding rod 7 is restricted by the guide blocks 19, which can reduce the tilting of the sliding rod 7 when it slides inside the movable frame 1, making the sliding of the sliding rod 7 more stable.

[0038] like Figures 6 to 7 As shown, multiple pushing blocks 20 are slidably connected inside the first sliding block 3, and the pushing blocks 20 are arranged in a circular array inside the first sliding block 3; a spring is fixed between the side wall of the pushing block 20 and the inner side wall of the first sliding block 3; multiple pushing grooves 21 are opened on the rotating shaft of the rotating roller 4; the pushing blocks 20 and the pushing grooves 21 are arranged correspondingly; during operation, when the rotating roller 4 rotates together with the take-up roller, the pushing blocks 20 engage with the pushing grooves 21, which increases the friction between the rotating roller 4 and the first sliding block 3 after the rotating roller 4 stops rotating, thereby effectively preventing the cable from falling off due to rotation after the take-up roller stops rotating.

[0039] like Figure 5As shown, a positioning rod 22 is fixedly connected inside the mobile frame 1; the first sliding block 3 is slidably connected to the positioning rod 22; during operation, when the first sliding block 3 slides inside the mobile frame 1, the positioning rod 22 restricts the sliding of the first sliding block 3, which makes the first sliding block 3 less prone to tilting during sliding, and makes the sliding of the first sliding block 3 more stable.

[0040] like Figure 8 As shown, a positioning block 23 is fixedly connected inside the movable frame 1; the positioning block 23 is set on the rotation axis corresponding to the first guide frame 10 and the second guide frame 11 inside the movable frame 1; during operation, when the first guide frame 10 and the second guide frame 11 rotate inside the movable frame 1, the rotation of the first guide frame 10 and the second guide frame 11 is restricted by the positioning block 23, which can make the rotation of the first guide frame 10 and the second guide frame 11 more stable.

[0041] like Figure 8 As shown, multiple balls 24 are provided between the first guide frame 10, the second guide frame 11, and the positioning block 23; the sidewalls of the balls 24 are in contact with the sidewalls of the positioning block 23; during operation, when the first guide frame 10 and the second guide frame 11 rotate inside the movable frame 1, by providing balls 24 between the first guide frame 10, the second guide frame 11, and the positioning block 23, the sliding friction between the first guide frame 10 and the positioning block 23 and the second guide frame 11 and the positioning block 23 can be changed into rolling friction, so that the friction between the first guide frame 10 and the positioning block 23 and the second guide frame 11 and the positioning block 23 is smaller, thereby reducing the wear between the first guide frame 10 and the positioning block 23 and the second guide frame 11 and the positioning block 23.

[0042] During operation, when it is necessary to wrap the cable with a sheath, the cable take-up roller can be placed on top of the rotating roller 4. The first sliding block 3 will move downward under the pressure of the take-up roller, and through the push of the spring, the rotating roller 4 can be aligned with the bottom side wall of the take-up roller. Then, the second sliding block 5 can be moved, causing the second sliding block 5 to drive the extrusion roller 6 to descend, thereby making the extrusion roller 6 fit against the top side wall of the take-up roller and fixing the take-up roller. Then, the fixing bolt 9 can be rotated, so that the fixing bolt 9 engages with the thread of the fixing plate 8, causing the fixing plate 8 to move the sliding rod 7. The clamping and fixing mechanism allows the take-up roller to be stably placed inside the movable frame 1, thereby controlling the rotation of the drive wheel 2 and moving the movable frame 1. After moving to the processing position, the cable can be passed through the extrusion port of the sheath extruder and wound onto the take-up device. During the take-up process, the take-up roller can rotate synchronously with the rotating roller 4 and the extrusion roller 6, making the take-up roller more stable during cable unwinding. The rotation of the drive wheel 2 moves the movable frame 1, thereby enabling cable unwinding, which makes cable unwinding more convenient.

[0043] When it is necessary to lay out the cable, the cable can be passed through the wire through holes of the first wire frame 10 and the second wire frame 11, so that the cable is closer to the center of the movable frame 1. This allows the cable to be inserted more accurately into the internal position of the extrusion port during cable laying, making the cable laying more precise. At the same time, anti-wear rollers 15 are set inside the first wire frame 10 and rollers are set inside the second wire frame 11, which reduces the friction between the cable and the first wire frame 10 and the second wire frame 11. This effectively avoids the situation where the cable is easily damaged due to excessive friction between the cable and the first wire frame 10 and the second wire frame 11.

[0044] When the rotating roller 4 is squeezed by the take-up roller and causes the first sliding block 3 to slide downward, the connecting rod 12 can pull the air-pushing plate 13, so that the air inside the sliding cavity of the air-pushing plate 13 is introduced into the sliding cavity of the sliding frame 16 through the air guide pipe 14, and pushes the sliding frame 16 to slide closer to the wire through hole, pushing the anti-wear roller 15 to fit with the cable, thereby making the cable more stable inside the wire through hole. At the same time, the connecting rod 12 guides the sliding of the first sliding block 3, making the sliding of the first sliding block 3 more stable.

[0045] When gas enters the sliding cavity of the sliding frame 16 through the gas guide pipe 14, the gas between the sliding cavities of each sliding frame 16 can be balanced by opening the gas guide holes 17 between the sliding cavities of each sliding frame 16. This makes the distance that the sliding frame 16 is pushed out more uniform, so that the cable can be better kept at the center position of the wire through hole of the first wire frame 10, and the anti-wear roller 15 can push the cable better.

[0046] When the sliding frame 16 slides inside the first guide frame 10, the sliding of the sliding frame 16 can be guided by the anti-detachment block 18 provided on the side wall of the sliding frame 16, thereby making the sliding of the sliding frame 16 more stable. At the same time, when the gas pushes the sliding frame 16, the anti-detachment block 18 is blocked by the first guide frame 10, which can effectively prevent the sliding frame 16 from detaching from the first guide frame 10.

[0047] When the sliding rod 7 slides inside the movable frame 1, the sliding of the sliding rod 7 is restricted by the guide block 19, which makes the sliding rod 7 tilt less when it slides inside the movable frame 1, and makes the sliding of the sliding rod 7 more stable.

[0048] When the rotating roller 4 rotates together with the take-up roller, the push block 20 engages with the push groove 21, which increases the friction between the rotating roller 4 and the first sliding block 3 after the rotating roller 4 stops rotating. This effectively prevents the cable from falling off due to rotation after the take-up roller stops rotating.

[0049] When the first sliding block 3 slides inside the movable frame 1, the sliding of the first sliding block 3 is restricted by the positioning rod 22, which makes the first sliding block 3 less likely to tilt during sliding, and makes the sliding of the first sliding block 3 more stable.

[0050] When the first guide frame 10 and the second guide frame 11 rotate inside the movable frame 1, the rotation of the first guide frame 10 and the second guide frame 11 is restricted by the positioning block 23, which makes the rotation of the first guide frame 10 and the second guide frame 11 more stable.

[0051] When the first guide frame 10 and the second guide frame 11 rotate inside the movable frame 1, the ball bearings 24 arranged between the first guide frame 10, the second guide frame 11 and the positioning block 23 can change the sliding friction between the first guide frame 10 and the positioning block 23 and the second guide frame 11 and the positioning block 23 into rolling friction, so that the friction between the first guide frame 10 and the positioning block 23 and the second guide frame 11 and the positioning block 23 is smaller, thereby reducing the wear between the first guide frame 10 and the positioning block 23 and the second guide frame 11 and the positioning block 23.
