Description

Technical Field

[0001] This utility model relates to the field of communication construction technology, specifically a conduit threader for communication construction. Background Technology

[0002] A conduit cable puller for communication construction is a tool specifically designed to guide and lay cables (such as network cables, telephone lines, fiber optics, etc.) in conduits, walls, or floors. It effectively solves the problem of difficult wiring in concealed works, improving construction efficiency and safety.

[0003] Existing conduit cable pullers used in communication construction can be referenced from Chinese Utility Model Patent Publication No. CN221530804U, which discloses a conduit cable puller including a connecting plate. The upper end of the connecting plate has four first connecting holes. A power component is fixedly installed at the lower end of the connecting plate. Four support columns are fixedly connected to the upper end of the connecting plate, and the four support columns are symmetrically distributed in pairs. The upper ends of two support columns on the same side are jointly fixedly connected to a fixing seat. Each of the two fixing seats has a slot at its front end, and the two slots jointly engage a cable clamping component. This utility model's conduit cable puller, by incorporating a power component, achieves the purpose of conveniently and quickly pulling cables through conduits, reducing the workload of workers; by incorporating a cable clamping component, it achieves the purpose of conveniently and quickly installing and disassembling cables and the cable puller, improving the success rate of cable pulling.

[0004] When the aforementioned equipment requires threading the wiring, the wire is passed through the elastic pad and installed inside the sleeve. The elastic pad has a certain degree of elasticity, which protects the wire while providing clamping force. However, the clamping force provided by the elastic pad is relatively limited and cannot be adjusted according to different wire diameters. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a conduit cable puller for communication construction, which has the advantages of flexible adjustment and efficient clamping of cables. By setting up components such as sealing rings, horizontal pipes, air supply pipes, air pumps, and air extraction pipes, air pressure is used to push the piston plate and connecting rod, which drives the arc-shaped clamping plate to move centripetally, thereby achieving adaptive clamping of cables of different diameters. This solves the problems of insufficient clamping force and non-adjustability of traditional elastic soft pads.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conduit cable puller for communication construction, comprising a connecting plate and a power assembly fixedly disposed at its bottom. Two fixing seats, parallel to the length direction of the connecting plate, are fixedly connected to the front and rear sides of the top of the connecting plate. A cable clamping assembly is commonly engaged at the top of the two fixing seats. The cable clamping assembly includes a mounting plate engaged above the top of the two fixing seats. A sleeve, parallel to the length direction of the mounting plate, is fixedly connected to the top of the mounting plate. The inner wall of the sleeve is fixedly connected with at least four arc-shaped clamping plates in a circumferential array. The four arc-shaped clamping plates move from the circumference of the sleeve towards its center. Annular shells coaxially arranged with the sleeve are fixedly fitted at both ends of the sleeve surface. Support seats are fixedly connected to the bottom of each of the two annular shells. The bottom of each of the two support seats is fixedly connected to the top left and right ends of the mounting plate. Two annular tubes coaxially arranged with the two annular shells are fixedly connected inside each of the two annular shells. At least four fixed tubes are fixedly connected in a circumferential array on the inner wall of each annular tube. Piston plates are slidably connected to the inner walls of each of the four fixed tubes. Connecting rods are fixedly connected to the side of each piston plate near the sleeve surface. The ends of the four connecting rods away from the four piston plates pass through the fixed tubes and extend into the sleeve, respectively fixedly connected to the opposite side of each of the four arc-shaped clamping plates. The surfaces of the four connecting rods are slidably connected to the four sides of the circumferential surface of the sleeve. A controller for controlling the entire device is fixedly connected to the front surface of the sleeve.

[0007] As a preferred embodiment of this utility model, each of the four corners of the top of the connecting plate is provided with a first connecting hole that runs vertically through the top, and the two fixed bases are fixedly connected to the left and right ends of their bottoms with support columns, and the bottoms of the four support columns are fixedly connected to the top of the connecting plate.

[0008] As a preferred embodiment of this utility model, the mounting plate is provided with locking rods on both the front and rear sides of its bottom, which are arranged along its length. The two locking rods are arranged parallel to the two fixing seats, and the two fixing seats are provided with locking grooves along their length.

[0009] As a preferred embodiment of this utility model, the two locking rods are adapted to the two locking slots, and electric telescopic rods are fixedly connected to the top left and right sides of the two locking rods. The top telescopic ends of the four electric telescopic rods are fixedly connected to the four corners of the bottom of the mounting plate.

[0010] As a preferred embodiment of this utility model, each of the plurality of fixed tubes is fixedly connected to a sealing ring at one end near the circumferential surface of the sleeve, the surfaces of the plurality of connecting rods are slidably connected to the inner walls of the plurality of sealing rings, and a horizontal tube is provided on the front side of the sleeve parallel to it.

[0011] As a preferred embodiment of this utility model, the left and right ends of the horizontal tube extend into the interior of the two annular shells and are fixedly connected to the two annular tubes on one side close to each other. A vertically arranged gas supply pipe is fixedly connected to the center of the bottom of the horizontal tube.

[0012] As a preferred embodiment of this utility model, the bottom of the gas supply pipe passes through the protective cover and is fixedly connected to the air pump outlet. The bottom of both the air pump and the protective cover are fixedly connected to the mounting plate. The air pump's suction end is fixedly connected to the suction pipe. The end of the suction pipe away from the air pump extends to the outside of the protective cover and is fixedly connected thereto.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When installing the wire clamping assembly, the operator can first align the clamping rod with the slot, start the electric telescopic rod to retract it, drive the mounting plate down, and let the clamping rod slide smoothly into the slot. Then the electric telescopic rod extends and lifts the mounting plate, so that the clamping rod is completely locked in the slot, preventing it from loosening or falling off due to vibration or resistance during the wire threading process.

[0014] 2. In this utility model, the cable to be installed is inserted through one end of the sleeve and passes through the central channel formed by four arc-shaped clamping plates. Then, the operator issues a command through the controller to start the air pump. The pump draws air from the outside through the suction pipe, pressurizes the air, and delivers it into the air supply pipe. The high-pressure gas flows upward along the air supply pipe into the horizontal pipe, and then through the horizontal pipe into the annular pipes inside the left and right annular shells. As gas continuously fills the annular pipes, it further diverts into multiple fixed pipes arranged in a circular array. When the gas pressure acts on the surface of the piston plate inside the fixed pipe, the piston plate slides along the inner wall of the fixed pipe towards the sleeve under the pressure of the gas. Because each piston... Each piston plate is fixedly connected to a connecting rod. Therefore, the movement of the piston plate drives the connecting rod to move synchronously from the outer circumference of the sleeve towards its central axis. The other end of the connecting rod is fixedly connected to the arc-shaped clamping plate. Thus, under the push of the four connecting rods, the four arc-shaped clamping plates are evenly gathered from the inner wall of the sleeve towards the center, gradually fitting the outer surface of the cable being threaded. This equipment can automatically adjust the clamping radius according to the actual diameter of the cable, achieving effective envelopment and firm clamping of network cables, coaxial cables, or optical cables of different thicknesses. Since the air pressure is adjustable, the clamping force can also be precisely controlled by the controller to avoid damage to the cable insulation layer due to excessive clamping or cable slippage during threading due to insufficient clamping.

[0021] Example 1 Reference Figure 1-4This is the first embodiment of the present invention, providing a conduit cable puller for communication construction, including a connecting plate 1 and a power component 4 fixedly installed at its bottom. Two fixing seats 3, parallel to the length direction of the connecting plate 1, are fixedly connected to the front and rear sides of the top of the connecting plate 1. A line clamping component 5 is commonly engaged at the top of the two fixing seats 3. The line clamping component 5 includes a mounting plate 53 engaged above the top of the two fixing seats 3. A sleeve 54, parallel to the length direction of the mounting plate 53, is fixedly connected to the top of the mounting plate 53. Since the power component 4 and related structures have already been disclosed in the referenced patent and are not improvements of this design, they will not be described in detail here. Furthermore, at least four arc-shaped clamping plates 55 are fixedly connected in a circumferential array on the inner wall of the sleeve 54. The four arc-shaped clamping plates 55 move from the circumference of the sleeve 54 towards its center. Annular shells 6, coaxially arranged with the sleeve 54, are fixedly fitted onto both the left and right ends of the sleeve 54. Support seats 601 are fixedly connected to the bottom of each of the two annular shells 6. The bottoms of the two support seats 601 are fixedly connected to the top left and right ends of the mounting plate 53. Two annular tubes 602, coaxially arranged with the two annular shells 6, are fixedly connected inside each of the two annular shells 6. The inner wall of each annular tube 602 is circumferentially arranged. The array is fixedly connected with at least four fixed tubes 603. Piston plates 604 are slidably connected to the inner walls of the four fixed tubes 603. Connecting rods 605 are fixedly connected to the side of the piston plates 604 near the surface of the sleeve 54. The ends of the four connecting rods 605 away from the four piston plates 604 pass through the fixed tubes 603 and extend into the inside of the sleeve 54. They are fixedly connected to the four arc-shaped clamping plates 55 on opposite sides. The surfaces of the four connecting rods 605 are slidably connected to the four sides of the circumferential surface of the sleeve 54. A controller 7 for controlling the entire device is fixedly connected to the front surface of the sleeve 54.

[0022] Specifically, the equipment mainly includes a connecting plate 1 and a power assembly 4 fixedly installed at its bottom. Two fixed seats 3, parallel to the length of the connecting plate 1, are fixedly connected to the front and rear sides of the top of the connecting plate 1. A cable clamping assembly 5 is clamped to the top of the two fixed seats 3. The cable clamping assembly 5 includes a mounting plate 53 clamped above the top of the two fixed seats 3. A sleeve 54, parallel to the length of the sleeve 54, is fixedly connected to the top of the mounting plate 53. At least four arc-shaped clamping plates 55 are fixedly connected in a circumferential array on the inner wall of the sleeve 54. The four arc-shaped clamping plates 55 move from the circumference of the sleeve 54 towards its center, thereby achieving radial clamping of the cable. Annular shells 6, coaxially arranged with the sleeve 54, are fixedly fitted at both ends of the sleeve 54. Support seats 601 are fixedly connected to the bottom of both annular shells 6. The bottoms of the two support seats 601 are connected to the mounting plate 53. The top left and right ends are fixedly connected to enhance the structural stability between the annular shell 6 and the sleeve 54. Two annular tubes 602, coaxially arranged with the annular shell 6, are fixedly connected inside each annular shell 6. At least four fixed tubes 603 are fixedly connected in a circumferential array on the inner wall of each annular tube 602. Piston plates 604 are slidably connected to the inner wall of the fixed tubes 603. Connecting rods 605 are fixedly connected to the side of the multiple piston plates 604 near the sleeve 54. The ends of the four connecting rods 605 away from the piston plates 604 pass through the fixed tubes 603 and extend into the sleeve 54, respectively, and are fixedly connected to the sides of the four arc-shaped clamping plates 55 away from each other. The rod body of the connecting rod 605 is slidably connected to the corresponding through hole on the circumferential surface of the sleeve 54 to ensure that the arc-shaped clamping plates 55 remain stable during radial movement. A controller 7 is also fixedly connected to the front surface of the sleeve 54 for controlling the entire device.

[0023] Furthermore, the power assembly 4 is first installed at the lower end of the connecting plate 1. At this time, the positions of the four second connecting holes are aligned with the four first connecting holes 11, so that the power assembly 4 is installed at the lower end of the connecting plate 1. When it is necessary to drive the wire guide to move in the pipe, the motor is started to drive the moving wheel to rotate, thereby making the whole unit move. At the same time, the connecting rods are rotated on both sides of the fixed plate, and the auxiliary wheel is installed using the buffer rod to provide auxiliary support for the wire guide as a whole, preventing the wire guide from tipping over during movement. This achieves the purpose of conveniently and quickly passing the wire through the pipe and reducing the workload of workers. The controller 7 issues a command to control the air pressure change inside the annular tube 602, pushing the piston plate 604 to slide in the fixed tube 603. Then, the connecting rod 605 drives the arc-shaped clamping plate 55 to move synchronously towards the center of the sleeve 54, realizing adaptive clamping for cables of different diameters. This structure overcomes the defects of insufficient clamping force and non-adjustable traditional elastic soft pads. It can provide stable, controllable, and uniform clamping force without damaging the cable, significantly improving the reliability and success rate of the wire threading process.

[0024] Example 2 In the second embodiment of this utility model, the top four corners of the connecting plate 1 are provided with a first connecting hole 11 that runs vertically through the top, and the bottom left and right ends of the two fixed seats 3 are fixedly connected with support columns 2, and the bottom of the four support columns 2 are fixedly connected to the top of the connecting plate 1.

[0025] Furthermore, the mounting plate 53 has two locking rods 51 on the front and rear sides of its bottom, which are arranged along its length. The two locking rods 51 are arranged parallel to the two fixing seats 3, and the two fixing seats 3 have slots 31 along their length.

[0026] Furthermore, the two locking rods 51 are adapted to the two locking slots 31, and electric telescopic rods 52 are fixedly connected to the top left and right sides of the two locking rods 51. The top telescopic ends of the four electric telescopic rods 52 are fixedly connected to the bottom four corners of the mounting plate 53.

[0027] Specifically, each of the four corners of the top of the connecting plate 1 has a through-hole 11. Support columns 2 are fixedly connected to the left and right ends of the bottom of each of the two fixing seats 3, for a total of four support columns 2. The bottoms of the four support columns 2 are fixedly connected to the four corners of the top of the connecting plate 1, thus stably supporting the two fixing seats 3 above the connecting plate 1. The fixing seats 3 are arranged parallel to the length of the connecting plate 1. The bottom of the mounting plate 53 has locking rods 51 extending along its length on both the front and rear sides. The two locking rods 51 are arranged parallel to the two fixing seats 3. The two fixing seats 3 have slots 31 along their length that match the locking rods 51. The locking rods 51 can slide into and fully embed themselves in the slots 31, achieving quick engagement between the line clamping assembly 5 and the fixing seats 3. The snap-fit ​​structure allows for easy disassembly and replacement of the line clamping assembly 5, facilitating maintenance or adaptation to different construction needs. Two snap-fit ​​rods 51 are fixedly connected to electric telescopic rods 52 on their top left and right sides, for a total of four electric telescopic rods 52. Their top telescopic ends are fixedly connected to the four corners of the bottom of the mounting plate 53. By controlling the telescopic movement of the electric telescopic rods 52, the overall height of the mounting plate 53 can be adjusted, thereby driving the sleeve 54 and the internal clamping structure to move up and down. This design not only ensures that the snap-fit ​​rods 51 can accurately and smoothly insert into or disengage from the slots 31, but also gives the entire line clamping assembly 5 a certain vertical adjustment capability to adapt to pipe inlets of different diameters or non-horizontal installation environments, improving the applicability of the equipment in complex construction sites.

[0028] Furthermore, to prevent the wire from shifting during movement and causing threading failure, a snap-fit ​​rod 51 is snapped into the slot 31, allowing the wire clamping assembly 5 to be quickly installed above the connecting plate 1. At the same time, an electric telescopic rod 52 is provided to accommodate pipes of different diameters, facilitating quick installation and removal of the wire and the threader.

[0029] Example 3 In the third embodiment of this utility model, a sealing ring 606 is fixedly connected to one end of a plurality of fixed tubes 603 near the circumferential surface of the sleeve 54, and a plurality of connecting rods 605 are slidably connected to the inner wall of the plurality of sealing rings 606. A horizontal tube 607 is provided on the front side of the sleeve 54 and is arranged parallel to it.

[0030] Furthermore, the left and right ends of the horizontal tube 607 extend into the interior of the two annular shells 6 and are fixedly connected to the two annular tubes 602 on one side close to each other. A vertically arranged gas supply pipe 608 is fixedly connected to the center of the bottom of the horizontal tube 607.

[0031] Furthermore, the bottom of the air supply pipe 608 passes through the protective cover 609 and is fixedly connected to the air outlet of the air pump 610. The bottom of both the air pump 610 and the protective cover 609 are fixedly connected to the mounting plate 53. The air pump 610 is fixedly connected to the air extraction end with an extraction pipe 611. The end of the extraction pipe 611 away from the air pump 610 extends to the outside of the protective cover 609 and is fixedly connected thereto.

[0032] Specifically, sealing rings 606 are fixedly connected to one end of each of the multiple fixed tubes 603 near the circumferential surface of the sleeve 54. The rods of the multiple connecting rods 605 pass through the inner wall of the sealing rings 606 and form a sliding seal with them. The function of the sealing rings 606 is to prevent gas from leaking from the gap between the fixed tubes 603 and the connecting rods 605, ensuring that the air pressure can effectively drive the piston plate 604 to move, thereby ensuring the stability and response speed of the clamping action. A horizontal tube 607 is provided on the front side of the sleeve 54, which is parallel to it. The left and right ends of the horizontal tube 607 extend into the interior of the two annular shells 6, respectively, and are fixedly connected to the side end faces of the two annular tubes 602 that are close to each other. The horizontal pipe 607 is connected to the annular pipes 602 on both sides to form a unified air supply channel. A vertically arranged air supply pipe 608 is fixedly connected to the center of the bottom of the horizontal pipe 607. The air supply pipe 608 extends downward and passes through the protective cover 609 before being fixedly connected to the air outlet end of the air pump 610. The bottoms of the air pump 610 and the protective cover 609 are both fixedly connected to the mounting plate 53 to ensure that the overall structure of the pneumatic assembly is stable and the operation is smooth. An air extraction pipe 611 is fixedly connected to the air extraction end of the air pump 610. The end of the air extraction pipe 611 away from the air pump 610 extends to the outside of the protective cover 609 and is fixedly connected to the protective cover 609 for drawing in air from the external environment.

[0033] Furthermore, when wiring is required, the wire is passed through the arc-shaped clamping plate 55 and installed inside the sleeve 54. To clamp wires of different diameters inside the sleeve 54, the operator starts the air pump 610 via the controller 7. After starting, the air pump 610 directly draws air from the environment through the suction pipe 611. The air is then transported through the suction pipe 611 and the air pump 610 to the air supply pipe 608. The gas transported to the air supply pipe 608 is then transported to the horizontal pipe 607 and gradually injected into the two annular pipes 602 inside the two annular shells 6. As gas is continuously injected into the two annular pipes 602, the gas... The gas can be gradually filled into the multiple fixed tubes 603. As the gas is continuously filled into the multiple fixed tubes 603, the gas pushes the multiple piston plates 604 to slide along the inner wall of the multiple fixed tubes 603. At this time, the multiple piston plates 604 can push the multiple connecting rods 605 from the circumference of the sleeve 54 to gradually approach its center. As the multiple connecting rods 605 gradually approach the center of the sleeve 54 from the circumference, the four arc-shaped clamping plates 55 can move from the periphery of the inner wall of the sleeve 54 to its center, until the inner wall of the four arc-shaped clamping plates 55 is in contact with the inner surface of the circuit inside the sleeve 54, so as to effectively fix the circuits of different diameters inside the sleeve 54 and provide good clamping force for the circuits of different diameters.

[0034] Working principle: First, install the power assembly 4 at the lower end of the connecting plate 1. Align the four second connecting holes with the four first connecting holes 11, ensuring the power assembly 4 is installed at the lower end of the connecting plate 1. When the wire guide needs to move within the pipe, start the motor to rotate the moving wheels, thus moving the entire assembly. Simultaneously, rotate the connecting rods on both sides of the fixed plate, and use the buffer rods to install auxiliary wheels to provide auxiliary support for the wire guide, preventing it from tipping over during movement. This facilitates quick and easy passage of the wire through the pipe, reducing the workload for workers. When wiring is required, the wire is passed through the arc-shaped clamping plate 55 and installed inside the sleeve 54. To clamp wires of different diameters inside the sleeve 54, the operator starts the air pump 610 via the controller 7. After starting, the air pump 610 directly draws air from the environment through the air extraction pipe 611. The air is then delivered to the air supply pipe 608 via the air extraction pipe 611 and the air pump 610. The gas delivered to the air supply pipe 608 is then delivered to the horizontal pipe 607 and gradually injected into the two annular pipes 602 inside the two annular shells 6 through the horizontal pipe 607. Inside, as gas is continuously injected into the two annular tubes 602, the gas gradually fills the multiple fixed tubes 603. As gas continues to fill the multiple fixed tubes 603, it pushes multiple piston plates 604 to slide along the inner walls of the multiple fixed tubes 603. At this time, the multiple piston plates 604 can push multiple connecting rods 605 from the circumference of the sleeve 54 towards its center. Because the multiple connecting rods 605 gradually approach the center of the sleeve 54 from its circumference, the four arc-shaped clamping plates 55 can respectively exit from inside the sleeve 54. The four arc-shaped clamping plates 55 move towards their center until the inner walls of the four arc-shaped clamping plates 55 are in contact with the inner surface of the wiring inside the sleeve 54, so as to effectively fix the wiring of different diameters inside the sleeve 54 and provide good clamping force for the wiring of different diameters. In order to prevent the wiring from shifting during the movement and causing the wiring failure, the clamping rod 51 is clamped into the clamping groove 31 by a snap-fit ​​method, so that the wiring clamping assembly 5 can be quickly installed above the connecting plate 1. At the same time, an electric telescopic rod 52 is provided so that it can be adapted to pipes of different diameters, which facilitates the quick installation and disassembly of wiring and wiring device.

[0035] In summary: by setting up components such as sealing ring 606, horizontal pipe 607, air supply pipe 608, air pump 610, and air extraction pipe 611, the piston plate 604 and connecting rod 605 are pushed by air pressure, which drives the arc-shaped clamping plate 55 to move centripetally, thereby completing the adaptive clamping of cables of different diameters and solving the problems of insufficient clamping force and non-adjustability of traditional elastic soft pads.
