Description

Technical Field

[0001] The invention belongs to the technical field of cable construction, and more specifically, relates to a precise cable laying-out device. Background Art

[0002] The cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire product used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. During the construction process, the cable needs to be laid out. The existing cable laying device consists of a reel with rotational freedom. The cable is wound on the reel. When laying out the cable, the driving part drives the reel to rotate and release the cable. Because the cable is soft, it is difficult to ensure that the tightness of the cable wrapped on the reel is always consistent. Therefore, the existing laying structure cannot accurately control the laying length, and can only roughly estimate the laying length by the number of rotations of the rotating wheel. In actual implementation, since the laying accuracy is difficult to control, it is often chosen to reserve more length for manual cutting after the reel rotates a predetermined number of times, resulting in an increase in construction costs.

It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

In the description of the present invention, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0024] The precise cable pay-out device provided by the present invention is now described.

[0025] like Figures 1 to 5As shown, the first embodiment of the present invention provides a precise cable pay-out device, including a cable pushing mechanism, a cutting mechanism and a control unit. The cable pushing mechanism is provided with a base 1 and an adjusting structure. A slideway 2 is provided on the base 1. Two slides 11 are slidably arranged on the slideway 2. A group of belt transmission components is provided on each slide 11. A channel for the cable 38 to pass through is formed between the belts 12 of the two groups of belt transmission components. The belts 12 are used to frictionally push the cable 38 forward. The slideway 2 and the channel are perpendicular to each other. The adjusting structure is connected to the two slides 11, and the adjusting structure is used to push the two slides 11 to slide along the slideway 2 and adjust the width of the channel; the cutting mechanism is provided at one end of the cable pushing mechanism, and is used to cut off the cable 38; the control unit is electrically connected to the cutting mechanism and the cable pushing mechanism, and is used to control the speed at which the cable pushing mechanism pushes the cable 38 and the cutting mechanism cuts the cable 38.

[0026] The cable precision pay-off device provided in this embodiment is provided with a cable pushing mechanism and a cutting mechanism compared with the prior art. The control unit is electrically connected to the cable pushing mechanism and the cutting mechanism. The control unit controls the speed of the cable pushing mechanism to push and release the cable 38, and performs timing. The length of the released cable 38 is calculated by controlling the speed and monitoring the time. When the cable 38 is released to the set length, the control unit controls the cutting mechanism to cut the cable 38. The cable pushing mechanism is provided with a base 1, a slideway 2 is provided on the base 1, two slides 11 are slidably provided on the slideway 2, and a group of belt transmission components is provided on each slide 11. A channel for the cable 38 to pass through is formed between the belts 12 of the two groups of belt transmission components. The cable 38 extends into the channel, and the belts 12 of the two groups of belt transmission components are in frictional contact with the cable 38. The movement of the belt 12 drives the cable 38 to move, thereby pulling the cable 38 out of the placement and continuously pushing it forward to achieve the pay-off of the cable 38. The cable pushing mechanism is also provided with an adjustment structure, and the width of the channel can be adjusted by the adjustment structure to adapt to the pay-off of cables 38 of different specifications. The precise cable pay-out device of the present invention can accurately control the pay-out length of the cable 38 and cut the cable 38 through a cutting mechanism, thereby effectively reducing construction costs and improving construction efficiency.

[0027] In this embodiment, Figure 5 As shown, a cable 38 is wound around a reel 39 having the freedom to rotate around its own axis, and the free end of the wound cable 38 extends between the two belts 12 of the cable pushing mechanism. The control unit controls the moving speed of the belt 12, and the cable 38 and the belt 12 move synchronously by friction. When the belt 12 starts to push the cable 38, the control unit synchronizes the timing, calculates the length of the cable 38 paid out by multiplying the pushing speed by the pushing time, and pre-sets the distance between the cutting mechanism and the entrance end of the cable pushing mechanism. Through calculation and program control, when the paid-out length of the cable 38 reaches the preset length, the portion of the cable 38 to be cut is moved to the cutting mechanism, and the control unit controls the cutting mechanism to cut.

[0028] In this embodiment, the placement of the cable 38 does not necessarily have to be a reel 39 structure, and the cables 38 can be placed in an orderly manner as long as the cable pushing mechanism can pull the cables 38 out of the placement of the cables 38 without knotting, obstruction, etc.

[0029] like Figures 1 to 3 As shown, a specific embodiment of the present invention is provided on the basis of the first embodiment as follows: the adjustment structure includes a fixed plate 14, a swivel 7, a first auxiliary gear 20, a second auxiliary gear 18, a transition gear 19, a driving gear 21, a first transmission gear 16, a second transmission gear 13, a first rack 5, a second rack 9 and a driving member, the fixed plate 14 is arranged at one end of the base 1, the fixed plate 14 is provided with a push hole 17, and the cable 38 can pass through the push hole 17; the swivel 7 is connected to the fixed plate 14 and is located on the outer side of the fixed plate 14, the swivel 7 is coaxial with the push hole 17, the swivel 7 can rotate around its own axis, and a first gear segment and a second gear segment are provided on the outer wall of the swivel 7; the first auxiliary gear 20 is rotatably arranged on the outer side of the fixed plate 14 and meshes with the first gear segment; the second auxiliary gear 18 is rotatably arranged on the outer side of the fixed plate 14 and meshes with the second gear segment; The transition gear 19 is rotatably arranged on the outer side of the fixed plate 14 and meshes with the second auxiliary gear 18; the driving gear 21 is rotatably arranged on the outer side of the fixed plate 14 and meshes with the first auxiliary gear 20; the first transmission gear 16 is rotatably arranged on the inner side of the fixed plate 14 and is coaxially connected to the first auxiliary gear 20; the second transmission gear 13 is rotatably arranged on the inner side of the fixed plate 14 and is coaxially connected to the transition gear 19; the first rack 5 is slidably arranged on the inner side of the fixed plate 14, and the sliding direction of the first rack 5 is parallel to the length direction of the slideway 2, and the first rack 5 is meshed with the first transmission gear 16; the second rack 9 is slidably arranged on the inner side of the fixed plate 14, and the sliding direction of the second rack 9 is parallel to the length direction of the slideway 2, the second rack 9 is meshed with the second transmission gear 13, and the first rack 5 and the second rack 9 are respectively connected to the two slides 11; the driving member is used to drive the driving gear 21 to rotate.

[0030] In this embodiment, Figure 2The operation is described from the perspective of . When the driving member pushes the driving gear 21 to rotate clockwise, the driving gear 21 is meshed with the first auxiliary gear 20, and the first auxiliary gear 20 rotates counterclockwise. The first auxiliary gear 20 is coaxially connected with the first transmission gear 16 and rotates synchronously. The first transmission gear 16 is meshed with the first rack 5, and the first transmission gear 16 drives the first rack 5 to move toward the inside of the slideway 2. Because the first auxiliary gear 20 is meshed with the first gear segment on the rotating ring 7, the rotating ring 7 is driven to rotate clockwise. The second gear segment on the rotating ring 7 is meshed with the second auxiliary gear 18, which drives the second auxiliary gear 18 to rotate counterclockwise. Because the second auxiliary gear 18 is meshed with the transition gear 19, the transition gear 19 is driven to rotate clockwise. The transition gear 19 is coaxially connected with the second transmission gear 13 and rotates synchronously. The second transmission gear 13 is meshed with the second rack 9, driving the second rack 9 to slide toward the inside of the slideway 2. The first rack 5 and the second rack 9 are both oriented toward the inner side of the slideway 2, so that the slide 11 connected to the first rack 5 and the second rack 9 also slides toward the inner side of the slideway 2, thereby making the belts 12 on the two slides 11 approach each other to adjust the width of the channel between the two belts 12. Similarly, when the driving member pushes the driving gear 21 to rotate counterclockwise, the first rack 5 and the second rack 9 are both moved toward the outer side of the slideway 2, and the two belts 12 are away from each other.

[0031] like Figures 1 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: the driving member is a push-up electric cylinder 8, one end of the push-up electric cylinder 8 is rotatably connected to the fixed plate 14, and the other end of the push-up electric cylinder 8 is rotatably connected to the end face of the driving gear 21.

[0032] In this embodiment, one end of the push-up electric cylinder 8 is rotatably connected to the fixed plate 14, and the other end of the push-up electric cylinder 8 is rotatably connected to the end surface of the driving gear 21. When the push-up electric cylinder 8 is extended, it will push the driving gear 21 to rotate a certain angle, thereby driving the first rack 5 and the second rack 9 to move a certain distance. Because there is no need to adjust the spacing between the belts 12, the driving gear 21 does not need to rotate a full circle. The push-up electric cylinder 8 can be extended or retracted by a certain length to drive the driving gear 21 to rotate a small angle for adjustment.

[0033] like Figures 1 to 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: two groups of adjustment structures are set, and the two groups of adjustment structures are respectively located at two ends of the base 1, the first racks 5 of the two groups of adjustment structures are connected to the same slide 11, and the second racks 9 of the two groups of adjustment structures are connected to the same slide 11.

[0034] In this embodiment, two groups of adjustment structures are provided, and the two groups of adjustment structures are respectively located at the two ends of the base 1, that is, at the two ends of the two slides 11. The adjustment structures synchronously push the slides 11 to rotate from both ends, thereby being able to push the two slides 11 to move more smoothly.

[0035] like Figure 1 and Figure 4 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: the cutting mechanism includes a connecting seat 4, a lifting electric cylinder 25, a cutting frame 10, a slice 23, and a cutting motor 24. The connecting seat 4 is connected to the fixed plate 14 at one end of the cable pushing mechanism; the lifting electric cylinder 25 is arranged on the connecting seat 4; the cutting frame 10 is connected to the lifting electric cylinder 25, and the lifting electric cylinder 25 is used to control the lifting and lowering of the cutting frame 10; the slice 23 is rotatably arranged on the cutting frame 10; the cutting motor 24 is arranged on the cutting frame 10, connected to the slice 23, and is used to control the rotational cutting of the slice 23.

[0036] In this embodiment, the cable 38 passes under the cutting frame 10 during the forward movement. When the cable 38 needs to be cut, the lifting electric cylinder 25 drives the cutting frame 10 to move downward, and the cutting motor 24 drives the cutter 23 to rotate to cut the cable 38.

[0037] like Figure 1 As shown, the present invention provides a specific implementation mode based on the above implementation mode as follows: two groups of cable pushing mechanisms are provided, and the two groups of cable pushing mechanisms are respectively located at two ends of the cutting mechanism.

[0038] In this embodiment, two groups of cable pushing mechanisms are provided, and the two groups of cable pushing mechanisms are respectively located at the two ends of the cutting mechanism, and the two ends of the connecting seat 4 of the cutting mechanism are respectively connected to the two groups of cable pushing mechanisms. When there is no need to cut, the two groups of cable pushing mechanisms drive the cable 38 forward through the friction between the belt 12 and the cable 38. When the cable 38 needs to be cut, the adjustment structure of the two groups of cable pushing mechanisms can start to act, so that the belt 12 moves toward the cable 38 and clamps the cable 38, so that the cable 38 to be cut is clamped from both sides, which can effectively prevent the cable 38 from moving when being cut, and better ensure the accuracy of cutting and the quality of the cutting plane. After the cutting is completed, the adjustment structure drives the belt 12 to release the cable 38.

The lower wall of the first through cavity 6 is provided with first avoidance holes which are the same in number as the outrigger electric cylinders 3, and the cylinder rods of the outrigger electric cylinders 3 can extend to the ground through the first avoidance holes to support the base 1.

[0040] In this embodiment, a first wheel 22 is provided at the bottom of the base 1, and the device can be placed in a suitable position by pulling during construction, which saves time and effort. At the same time, a first through cavity 6 is provided on the base 1, and a first avoidance hole is provided on the lower wall of the first through cavity 6. The number of the first avoidance holes is the same as that of the outrigger electric cylinder 3 and they correspond one to one. The cylinder rod of the outrigger electric cylinder 3 can extend out of the first through cavity 6 through the first avoidance hole and contact the ground. When the device is pulled to a suitable position, the control unit controls the cylinder rod of the outrigger electric cylinder 3 to extend, the outrigger electric cylinder 3 contacts the ground, and the base 1 is lifted, and the first wheel 22 is detached from the ground, so that the base 1 is fixed, thereby preventing the device from moving when the cable 38 is released.

[0043] Because the cable 38 may be bent or piled up after leaving the cable pushing mechanism during the process of laying out and pushing, multiple operators are required to operate together in the actual construction process, with one operator assigned at a certain distance. Once bending or the like is found, the cable 38 is combed. In this embodiment, a support mechanism is added, and multiple support mechanisms can be provided, one at a certain interval. After the cable 38 is sent out from the cable pushing mechanism, it is placed on the support mechanism. Several support mechanisms support and transmit the cable 38, freeing up manpower.

[0044] In this embodiment, the roller assembly includes a bracket 27 and a support roller 35. The bracket 27 includes two inclined sub-frames, and the two sub-frames are arranged in a V shape. A support roller 35 is rotatably arranged on each sub-frame, and the cable 38 is placed between the support rollers 35 on the two sub-frames.

[0045] In this embodiment, the bottom end of the support seat 26 of the support mechanism is provided with a second wheel 37, so that the support mechanism can be moved to a suitable position by pushing. At the same time, the support seat is provided with a second through cavity 31, and the bottom surface of the second through cavity 31 is provided with a plurality of threaded holes, and a bolt support leg 28 is threadedly connected in each bolt hole. When the support mechanism is moved to a suitable position, the bolt support leg 28 is rotated so that the bolt support leg 28 contacts and presses the ground, so that the support seat 26 is fixed.

[0046] In this embodiment, the lower end of the bolt support foot 28 can be rotatably provided with a pad foot 40, and the bolt support foot 28 contacts the ground through the pad foot 40. Because the bolt support foot 28 is rotatably connected with the pad foot 40, when the pad foot 40 contacts the ground, the bolt support foot 28 can be continuously rotated to lift the support seat 26 and lift the second wheel 37 off the ground.

[0047] like Figures 6 to 8 As shown, a specific embodiment of the present invention provided on the basis of the above-mentioned embodiment is as follows: taking the pushing direction of the cable 38 as the front-to-back direction, arc-shaped channels 32 are provided on the left and right sides of the base 1, and hanging rods 29 are correspondingly provided on the left and right sides of the support seat 26, one end of the hanging rod 29 is rotatably connected to the support seat 26, and the other end of the hanging rod 29 is rotatably provided with a roller 36, and the roller 36 can roll along the arc-shaped channel 32 on the same side as the rotation of the hanging rod 29, and a accommodating cavity is provided on the side wall of the arc-shaped channel 32, and a stopper 33 and a spring 34 are provided in the accommodating cavity, the stopper 33 is slidably arranged and can extend into the arc-shaped channel 32 from the accommodating cavity, and the spring 34 is used for pushing the stopper 33 to extend into the bottom of the roller 36 in the arc-shaped channel 32, limiting the rolling of the roller 36 along the arc-shaped channel 32, and realizing the hanging connection between the support seat 26 and the base 1.

[0048] In this embodiment, the support mechanism and the cable pushing mechanism are detachably connected. When the support mechanism is connected to the cable pushing mechanism, they can be moved to the construction position together. When the support mechanism is disconnected from the cable pushing mechanism, the support mechanism can be independently adjusted to a suitable position.

[0049] In this embodiment, arc-shaped channels 32 are provided on both sides of the base 1, and a receiving cavity is provided on the side wall of the arc-shaped channel 32. A stopper 33 and a spring 34 are provided in the receiving cavity. The stopper 33 is slidably arranged and can be extended from the receiving cavity into the arc-shaped channel 32 under the push of the spring 34. Hanging rods 29 are provided on both sides of the support seat 26. One end of the hanging rod 29 is rotatably connected to the support seat 26, and the other end of the hanging rod 29 is rotatably provided with a roller 36. The roller 36 can roll along the arc-shaped channel 32 as the hanging rod 29 rotates. When the support mechanism needs to be connected with the cable pushing mechanism, the stopper 33 is manually pushed back into the receiving cavity, the spring 34 is compressed, the hanging rod 29 is rotated, and the roller 36 enters the arc-shaped channel 32 on the same side as the hanging rod 29 rotates, and moves to the upper end of the arc-shaped channel 32, and then the stopper 33 is released. The stopper 33 is pushed into the lower part of the roller 36 in the arc-shaped channel 32 under the push of the spring 34, and the roller 36 is restricted from rolling along the arc-shaped channel 32. Because the hanging rods 29 on the left and right sides of the support seat 26 are connected to the arc-shaped channels 32 on the left and right sides of the base 1, the support mechanism cannot move forward and backward or left and right, and can only move together with the cable pushing mechanism. When the connection needs to be disconnected, the stopper 33 is pushed into the accommodating cavity, and the hanging rod 29 automatically rotates downward along the arc-shaped channel 32 under the action of gravity.

[0050] In this embodiment, the above-mentioned detachable structure is not limited to the connection between the cable pushing mechanism and the supporting mechanism, and adjacent supporting mechanisms can also be connected in this way, so that multiple supporting mechanisms can be set up, which is more convenient for long-distance cable laying.

[0051] In this embodiment, cover plates 30 are disposed on both the left and right sides of the base 1 , and the cover plates 30 cover the accommodating cavity.
