Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically a power construction pipeline cable puller. Background Technology

[0002] In construction scenarios such as power line laying, cable renovation, and pipeline wiring, conduit cable pullers are the core equipment for efficiently pulling cables into and protecting pipelines. To improve adaptability and automation, the industry has developed multi-functional cable pulling structures, such as the power construction conduit cable puller disclosed in patent CN222981128U, which enables quick replacement of cables of different specifications through a detachable drum and adapts to cable tension and transmission speed with the help of elastic adjustment components, which greatly improves efficiency compared to traditional manual cable pulling.

[0003] However, the solution still has some shortcomings in its core performance: First, the vertical fixed layout of the drum leads to unstable cable laying height. When the cable is laid out evenly, the laying height is constantly different, which creates a dynamic height difference with the tension wheel at a fixed height in the conductor device. This can easily cause the cable to jam, get blocked, or even derail from the wheel groove, requiring frequent shutdowns for adjustment. Second, the problem of cable friction is prominent. The inner wall of the pipe is in continuous contact with the outer surface of the cable, especially when there are many bends and the cable length increases, the friction increases significantly.

[0004] Therefore, developing a power construction conduit cable puller that can eliminate the height difference of the cable laying, reduce the friction between the cable and the pipe, and ensure smooth cable pulling has become an urgent need to solve construction pain points and improve laying efficiency and safety. Utility Model Content

[0005] The purpose of this utility model is to provide a power construction pipeline cable puller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power construction conduit cable threader includes a base and a winding roller. A support frame is fixedly mounted on the base, and a fixing component for fixing the winding roller is located on one side of the support frame on the base. The fixing component is movable via a multi-stage electric push rod. A pair of wire assemblies are mounted side by side on the support frame, and a lubrication component is located between the two wire assemblies. The lubrication component includes a fixing frame, a three-way valve, an oiling wheel, an oil inlet main pipe, a branch pipe, a rotary joint, an oil pump, and an oil tank. The fixing frame is fixedly mounted on the support frame, and a pair of oiling wheels are rotatably mounted inside the fixing frame. The oiling wheels have a hollow structure and multiple oil outlet holes, and oil-absorbing cotton is sleeved on the oiling wheels. A rotary joint is mounted on the oiling wheel, and a branch pipe is mounted on the rotary joint. The branch pipe is connected to the oil inlet main pipe through the three-way valve. The oil inlet main pipe is connected to the output end of an oil pump located inside the support frame, and the input end of the oil pump is connected to the oil tank.

[0008] As a further embodiment of this utility model: the wire assembly includes a pair of wire wheels rotatably mounted on a support frame, one of which is driven by a first motor disposed within the support frame.

[0009] As a further embodiment of this utility model: another guide wheel and the same side oiling wheel are both movably set through the first slider, the support frame is provided with a first movable hole for the first slider to slide, and the support frame is also provided with an adjustment component for adjusting the distance between the guide wheels and the distance between the oiling wheels.

[0010] As a further embodiment of this utility model: the adjustment assembly includes a lead screw rotatably disposed on the top surface of the inner cavity of the support frame and guide rods symmetrically disposed on both sides of the lead screw. The lead screw is driven by a second motor disposed inside the support frame, and a nut is installed on the lead screw. A sliding sleeve is slidably disposed on the guide rod, and the sliding sleeve is connected to the nut through a connecting rod. Three first sliders are respectively fixedly installed on the nut and two sliding sleeves.

[0011] As a further embodiment of this utility model: the fixing frame is also provided with a second movable hole, and a second slider is slidably arranged in the second movable hole, and one of the rotary joints is fixedly installed on the second slider.

[0012] As a further embodiment of this utility model: the fixing component includes a support plate rotatably mounted on the telescopic end of the multi-stage electric push rod, a positioning post fixedly mounted on the support plate, and a limiting plate threaded onto the positioning post, with a knob installed on the limiting plate.

[0013] As a further embodiment of this utility model: a positioning ring is also fixedly provided on the support frame between the fixing component and the wire assembly, and the cable passes through the positioning ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention solves the problems of cable blockage and derailment, and friction damage between pipes and cables in traditional cable pullers through the design of "dynamic leveling and anti-jamming + lubrication and resistance reduction protection device". For anti-jamming, a multi-stage electric push rod can drive the fixed component and winding roller to rise and fall synchronously, dynamically matching the height of the conductor assembly and eliminating cable jamming and derailment caused by height differences. The positioning ring on the support frame guides and constrains the cable in the initial stage of cable laying, ensuring that the cable is stably transported to the conductor wheel along a straight line, further avoiding lateral deviation caused by laying inertia, forming a dual guarantee of "leveling-guidance" to ensure a smooth cable pulling process. Regarding the resistance reduction protection device, the lubrication component, through the cooperation of a hollow oiling wheel and oil-absorbing cotton, evenly penetrates and coats the lubricating oil on the cable surface, forming a complete oil film to reduce the coefficient of friction and avoid scratches on the inner wall of the pipe and wear on the outer sheath of the cable. The rotary joint ensures that the oil path does not entangle or break when the oiling wheel rotates, the oil pump provides a stable oil supply, and the three-way valve adjusts the oil volume as needed, ensuring uniform oiling and unobstructed oil flow throughout the process, solving the problems of uneven and wasteful manual oiling in traditional methods.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Example 1

[0025] Please see Figure 1-6 A power construction conduit cable threading device includes a base 1 and a winding roller 2. The base 1 provides a stable support foundation for the entire device. The winding roller 2 is used to wind the cable to be threaded. A support frame 3 is fixedly installed on the base 1, and a fixing component 4 for fixing the winding roller 2 is installed on one side of the support frame 3 on the base 1. The fixing component 4 is movable via a multi-stage electric push rod 5. The support frame 3 provides an installation carrier for the conductor assembly and lubrication assembly, and its frame structure ensures that the layout of each component is reasonable and does not interfere with each other. The fixing component 4 achieves precise fixing of the winding roller 2, preventing the cable from shifting due to the shaking of the winding roller 2 during cable release. The multi-stage electric push rod 5 can drive the fixing component 4 and the winding roller 2 to move up and down synchronously, dynamically adjusting the cable release height to ensure that the cable release height is always consistent with the conductor assembly, eliminating jamming and derailment problems caused by height differences.

[0026] A pair of wire assemblies are installed side by side on the support frame 3, and a lubrication assembly is provided between the two wire assemblies. The wire assemblies provide power for cable transmission and guidance constraint to prevent the cable from deviating during transmission. The lubrication assembly evenly applies lubricating oil to the surface of the cable to reduce friction between the cable and the inner wall of the pipe, thus solving the problems of pipe scratches and cable jamming in the prior art.

[0027] The lubrication assembly includes a fixed frame 8, a three-way valve 9, an oiling roller 10, an oil inlet main pipe 12, a branch pipe 13, a rotary joint 28, an oil pump 14, and an oil tank 15. The fixed frame 8 is fixedly mounted on the support frame 3, and a pair of oiling rollers 10 are rotatably installed inside the fixed frame 8. The oiling rollers 10 have a hollow structure and multiple oil outlet holes, and oil-absorbing cotton 11 is fitted on the oiling rollers 10. The fixed frame 8 provides stable installation support for the oiling rollers 10, ensuring that the position of the oiling rollers 10 does not shift when rotating. The hollow structure of the oiling rollers 10 cooperates with the oil outlet holes to evenly deliver lubricating oil to the oil-absorbing cotton 11. After absorbing the lubricating oil, the oil-absorbing cotton 11 can evenly spread the oil on the surface of the cable as the oiling rollers 10 rotate, avoiding direct dripping of lubricating oil and causing waste. At the same time, it ensures that a complete oil film is formed on the outer surface of the cable, which greatly reduces the coefficient of friction with the inner wall of the pipe.

[0028] A rotary joint 28 is installed on the oiling roller 10, and a branch pipe 13 is installed on the rotary joint 28. The branch pipe 13 is connected to the main oil inlet pipe 12 through a three-way valve 9. The main oil inlet pipe 12 is connected to the output end of the oil pump 14 installed in the support frame 3, and the input end of the oil pump 14 is connected to the oil tank 15. The rotary joint 28 ensures that the oil circuit is always unobstructed when the oiling roller 10 rotates, avoiding pipe entanglement and breakage. The branch pipe 13 divides the lubricating oil to the two oiling rollers 10 to achieve synchronous oil supply. The three-way valve 9 can adjust the oil circuit opening and closing and the flow rate to adapt to the oiling needs of different cables. The oil pump 14 provides stable power to the oil circuit, draws lubricating oil from the oil tank 15 and delivers it to the oiling roller 10 to ensure continuous and stable oil supply.

[0029] Example 2

[0030] Please see Figure 1 , Figure 2 and Figure 5 The wire assembly includes a pair of wire wheels 6 rotatably mounted on a support frame 3. One of the wire wheels 6 is driven by a first motor 7 installed inside the support frame 3. The pair of wire wheels 6 clamp the cable from both sides to prevent the cable from shifting vertically during transmission. The first motor 7 provides rotational power to the wire wheels 6, driving the cable forward at a uniform speed, replacing the traditional manual pushing of the cable, reducing labor intensity, and ensuring stable threading speed and improving threading efficiency.

[0031] Example 3

[0032] Please see Figure 3 , Figure 5 and Figure 6 The other guide wheel 6 and the oiling wheel 10 on the same side are both movably set through the first slider 16. The support frame 3 is provided with a first movable hole for the first slider 16 to slide. The support frame 3 is also provided with an adjustment component for adjusting the distance between the guide wheels 6 and the distance between the oiling wheels 10. The first slider 16 cooperates with the first movable hole to provide a sliding channel for the guide wheels 6 and the oiling wheels 10, so that the distance can be adjusted according to the cable diameter. The adjustment component realizes the precise adjustment of the distance, ensuring that the guide wheels 6 and the oiling wheels 10 can fit tightly against cables of different diameters, which avoids both loose clamping that causes cable displacement and excessive clamping that damages the cable.

[0033] Example 4

[0034] Please see Figure 5 and Figure 6The adjustment assembly includes a lead screw 17 rotatably mounted on the top surface of the inner cavity of the support frame 3 and guide rods 20 symmetrically arranged on both sides of the lead screw 17. The lead screw 17 is driven by a second motor 19 installed inside the support frame 3, and a nut 18 is installed on the lead screw 17. A sliding sleeve 21 is slidably mounted on the guide rod 20. The sliding sleeve 21 is connected to the nut 18 through a connecting rod 29. Three first sliders 16 are respectively fixedly mounted on the nut 18 and the two sliding sleeves 21. The second motor 19 drives the lead screw 17 to rotate, which drives the nut 18 to move up and down through threaded transmission. The guide rods 20 and the sliding sleeves 21 cooperate to limit the movement trajectory of the nut 18, preventing the nut 18 from deflecting when the lead screw 17 rotates. The connecting rods 29 drive the sliding sleeves 21 to move synchronously with the nut 18, so that the three first sliders 16 drive the corresponding guide wheel 6 and oiling wheel 10 to adjust the spacing synchronously, ensuring consistent adjustment and avoiding uneven cable stress caused by unilateral adjustment.

[0035] Example 5

[0036] Please see Figure 3 and Figure 4 The fixed frame 8 is also provided with a second movable hole, and a second slider 22 is slidably arranged in the second movable hole. One of the rotary joints 28 is fixedly installed on the second slider 22. The second slider 22 can slide along the second movable hole as the position of the oiling wheel 10 changes, ensuring that the rotary joint 28 and the oiling wheel 10 always remain coaxially connected, avoiding the oil circuit breakage or leakage caused by the oiling wheel 10 pulling the oil pipe when it moves, and ensuring the continuous and stable operation of the lubrication component.

[0037] Example 6

[0038] Please see Figure 1 and Figure 2 The fixing assembly 4 includes a support plate 23 rotatably mounted on the telescopic end of the multi-stage electric push rod 5, a positioning post 24 fixedly mounted on the support plate 23, and a limiting plate 25 threadedly mounted on the positioning post 24. A knob 26 is installed on the limiting plate 25. The support plate 23 provides bottom support for the winding roller 2, and its rotation design allows it to rotate synchronously with the cable unwinding, reducing friction between the winding roller 2 and the support plate 23. The positioning post 24 is inserted into the center hole of the winding roller 2 to achieve precise positioning of the winding roller 2. The limiting plate 25 is fixed to the top of the winding roller 2 by a threaded connection to prevent the winding roller 2 from coming off upwards during cable unwinding.

[0039] Example 7

[0040] Please see Figure 1A positioning ring 27 is also fixedly installed on the support frame 3 between the fixing component 4 and the wire assembly. The cable passes through the positioning ring 27. The positioning ring 27 guides and constrains the cable released from the winding roller 2, ensuring that the cable is stably transported in a straight line between the two wire wheels 6, avoiding the cable from shifting left and right due to the inertia of the cable release, and further reducing the risk of jamming and derailment.

[0041] Working principle:

[0042] Before threading, place the winding roller 2 on the positioning post 24, turn the knob 26 to tighten the limit plate 25 to fix the winding roller 2; start the second motor 19 to drive the lead screw 17 to rotate, which will drive the nut 18 and the sliding sleeve 21 to move synchronously, and adjust the distance between the guide wheel 6 and the oiling wheel 10 to match the current cable diameter.

[0043] During cable laying, the multi-stage electric push rod 5 is controlled to adjust the laying height of the winding roller 2 according to the height of the conductor assembly, ensuring that the cable and the conductor wheel 6 are at the same horizontal height. One end of the cable is passed through the positioning ring 27 and fed between the two conductor wheels 6. The first motor 7 is started to drive the conductor wheel 6 to rotate, and the cable is conveyed forward. At the same time, the oil pump 14 is started to draw lubricating oil from the oil tank 15 and send it to the oiling wheel 10 through the oil inlet main pipe 12, three-way valve 9, branch pipe 13 and rotary joint 28. The lubricating oil permeates to the oil-absorbing cotton 11 through the oil outlet hole and is evenly coated on the surface of the cable as the oiling wheel 10 rotates.

[0044] After being coated with lubricating oil, the cable continues to be fed forward and smoothly threaded into the power conduit. During the process, the positioning ring 27 keeps the cable guided, and the multi-stage electric push rod 5 dynamically adjusts the height of the winding roller 2 to eliminate height differences. The oil coating reduces friction with the inner wall of the conduit, preventing jamming and scratches. After the operation is completed, the motor and oil pump are turned off, and the winding roller 2 can be replaced by unscrewing the limit plate 25 to adapt to the next operation. This device solves the problems of cable blockage and derailment, and conduit friction damage in the background technology through "dynamic height adjustment and lubrication to reduce resistance," thereby improving cable threading efficiency and safety.

[0045] The motor involved in the embodiments, its matching control system, electromagnetic switch and pipeline circuit can also be provided by the manufacturer. In addition, the control module for controlling the extension and retraction of the multi-stage electric push rod and the start and stop of the oil pump involved in this utility model is existing technology, which can be fully implemented by those skilled in the art, and there is no need to elaborate. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0046] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
