Description

Technical Field

[0001] This invention relates to the field of electrical engineering technology, and in particular to an auxiliary device for connecting electrical pipelines and its usage method. Background Technology

[0002] Electrical conduits are pipes used to install wires and cables, typically made of metal or plastic. Their primary function is to protect wires and cables from damage or cut. To achieve precise connections between two electrical conduits, connection aids are required.

[0003] While existing electrical conduit connection auxiliary devices can provide basic connection assistance, they suffer from several drawbacks. The lack of highly adjustable support structures and the tendency for conduits to bend can lead to breakage, cracking, and scratches on insulation layers, posing a safety hazard of electrical leakage, especially when connecting long conduits. Therefore, it is necessary to provide an electrical conduit connection auxiliary device and its usage method to address these technical problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that, although the existing electrical pipeline docking auxiliary devices can achieve simple docking assistance functions in actual use, they are prone to being pulled apart, cracked, or having their insulation layer scratched when docking long pipelines due to the lack of highly adjustable support structures and the bending of the pipelines, which poses a safety hazard of leakage.

[0005] To address the aforementioned deficiencies in the prior art, the present invention provides an electrical conduit connection auxiliary device, comprising a base, on which: The pipeline docking structure is used to fix the pipeline and adjust its position; the pipeline docking structure is symmetrically arranged along the axial direction of the base and can slide back and forth along the axial direction of the base. A cleaning structure, installed on the pipeline connection structure, is used to clean the inner and outer walls of the pipeline; The pipeline support structure is located outside the pipeline docking structure and is symmetrically arranged at both ends of the base. Its overall height is adjustable, and it provides auxiliary support for the movement of electrical pipelines. It includes two sets of upper cavity plates and lower cavity plates. Each set of upper cavity plates and lower cavity plates is rotatably connected by two threaded columns. The upper ends of the two threaded columns extend out of the upper cavity plate and are rotatably connected to the top plate. The lower ends of the two threaded columns extend into the lower cavity plate. Pulleys are respectively sleeved on the two threaded columns located in the lower cavity plate. A transmission belt is sleeved on the outside of the two pulleys. A third motor is installed at the bottom of the lower cavity plate. The output shaft of the third motor passes through the lower cavity plate and is connected to the bottom end of one of the threaded columns. Both the upper cavity plate and the lower cavity plate are fixedly installed with rectangular frame plates on the side near the pipeline docking structure. A bidirectional lead screw is provided inside the rectangular frame plate. One end of the bidirectional lead screw is connected to the output shaft of the second motor installed on the rectangular frame plate. Mounting seats are symmetrically screwed onto the bidirectional lead screw. Each mounting seat is equipped with a support seat. The side of the support seat that contacts the pipeline is an inclined surface. A limit roller is rotatably connected to the inclined surface. The pipeline is clamped by the inscribed circle formed by the inclined surfaces of the four support seats.

[0006] Furthermore, the pipeline support structure also includes fixed platforms installed on both sides of the base. A fifth hydraulic telescopic rod is installed at the bottom of the fixed platform, and the upper end of the fifth hydraulic telescopic rod passes through the fixed platform and is fixedly connected to the lower cavity plate.

[0007] Furthermore, the pipeline support structure also includes a telescopic column installed between the lower cavity plate and the upper cavity plate.

[0008] Further, the pipeline docking structure includes two slidable docking seats mounted on the base. Each docking seat consists of two opposing semicircular rings. A connecting plate is installed on the side where the two semicircular rings meet. A third hydraulic telescopic rod is installed between the two corresponding connecting plates. Each docking seat is equipped with a cleaning structure.

[0009] Furthermore, the pipeline docking structure also includes a slide rail disposed within the base. The slide rail contains a bidirectional threaded rod rotatably connected to the base. A fourth motor is disposed inside the slide rail. The output shaft of the fourth motor is connected to the bidirectional threaded rod. Movable seats are symmetrically screwed onto the bidirectional threaded rod. The top of each movable seat is fixedly connected to the docking seat.

[0010] Furthermore, the pipeline docking structure also includes a plurality of first hydraulic telescopic rods installed along the axial direction of the docking seat, and the output end of each first hydraulic telescopic rod is connected to a pipeline clamp, which is located on the inner wall of the docking seat.

[0011] Further, the cleaning structure includes semi-toothed rings installed on opposite sides of two docking seats. Each of the two corresponding semi-toothed rings has an extension plate on its opposite surface. A sixth hydraulic telescopic rod connects the extension plate to the semi-toothed rings. A second and fourth hydraulic telescopic rod are vertically installed on the extension plate, respectively. An installation head is fixedly connected to the output end of both the second and fourth hydraulic telescopic rods. A built-in cleaning brush is inserted into the lower installation head, and an external cleaning brush is inserted into the upper installation head. A first motor is installed on the top of the docking seats. Gears are sleeved on the outer side of the output shaft of the first motor, and these gears mesh with the semi-toothed rings.

[0012] Further, a sliding groove is provided on the docking seat, and three ball-head components are evenly slidably connected inside the sliding groove. One end of each of the three ball-head components is fixedly connected to a semi-toothed ring.

[0013] Furthermore, the cleaning structure also includes insertion holes on the mounting head, the built-in cleaning brush, and the external cleaning brush. The built-in cleaning brush and the external cleaning brush are connected to the mounting head respectively through the cooperation of the tension spring, the insertion rod, and the insertion holes.

[0014] On the other hand, the present invention also provides a method of using an electrical conduit connection auxiliary device, comprising the following steps: S1. Place the base of this auxiliary device in a suitable working area, and insert one end of each of the two electrical conduits into the conduit support structure and the conduit docking structure on both sides respectively. At this time, the built-in cleaning brush is located inside the electrical conduit, while the external cleaning brush is located outside the electrical conduit. S2. Adjust the fifth hydraulic telescopic rod of the pipeline support structure so that the lower limit roller contacts the bottom of the electrical pipeline, and at the same time adjust the first hydraulic telescopic rod so that multiple pipeline clamps fix the electrical pipeline. S3. Start the third motor of the pipeline support structure, and use it in conjunction with the pulley and transmission belt to make the two threaded columns rotate synchronously, driving the outer upper cavity plate to drive the upper rectangular frame plate and support seat to move downward, so that the upper limit roller contacts the top of the electrical pipeline, at which point the length of the telescopic column is shortened. S4. Adjust the second hydraulic telescopic rod to shorten it, which will drive the mounting head connected to its output end to move the built-in dust cleaning brush so that it contacts the inner wall of the electrical conduit. S5. Adjust the extension of the fourth hydraulic telescopic rod to drive the mounting head connected to its output end to move the external cleaning brush so that it contacts the outer wall of the electrical conduit. S6. Start the first motor, drive the gear connected to its output shaft to rotate, drive the half gear ring to drive the built-in cleaning brush and the external cleaning brush to rotate, and clean the inner and outer walls of the electrical pipeline respectively. S7. After the cleaning work is completed, adjust the sixth hydraulic telescopic rod to extend it and move the extension plate so that the built-in cleaning brush and the external cleaning brush are disengaged from the electrical conduit. Then adjust the fourth hydraulic telescopic rod and the second hydraulic telescopic rod again so that the built-in cleaning brush and the external cleaning brush are raised to the highest position. S8. Start the fourth motor, which drives the bidirectional threaded rod connected to its output shaft to rotate. This drives the two movable seats on the outside to move the pipeline docking structure in opposite directions, so that the two electrical pipelines are adjusted to a suitable distance. The two electrical pipelines are then connected and fixed using the pipeline joint.

[0015] Compared with related technologies, the present invention has the following beneficial effects: This invention adds auxiliary support structures to both sides of the pipeline docking structure, which can provide auxiliary support for the movement of electrical pipelines. By starting a second motor, the bidirectional lead screw connected to its output shaft rotates, controlling the two mounting seats on the outer side to move the corresponding two support seats in opposite or opposite directions. Furthermore, by starting a third motor, in conjunction with a pulley and a transmission belt, the two threaded columns rotate synchronously, driving the upper cavity plate on the outer side to move the rectangular frame plate and support seats downwards. In summary, this allows the four limiting rollers on the same side to contact the outer side of the electrical pipeline, thus enhancing the safety of the electrical pipeline and avoiding friction. The pipeline auxiliary support structure has high adjustability and strong adaptability, solving the technical problem that existing electrical pipeline docking auxiliary devices, although they can achieve simple docking assistance functions, are prone to breakage, cracking, and damage to the insulation layer when docking long pipelines due to the lack of highly adjustable auxiliary support structures and pipeline bending, posing a safety hazard of leakage.

[0017] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate typical embodiments of the present invention.

[0018] Example 1 like Figure 1-4 As shown, an electrical wiring connection auxiliary device includes a base 1, on which: The pipeline docking structure is used to fix the pipeline and adjust the position of the pipeline; the pipeline docking structure is symmetrically arranged along the axis of the base 1 and can slide back and forth along the axis of the base 1. A cleaning structure, installed on the pipeline connection structure, is used to clean the inner and outer walls of the pipeline; The pipeline support structure is located outside the pipeline docking structure and is symmetrically arranged at both ends of the base 1. The overall height is adjustable, and it provides auxiliary support for the movement of electrical pipelines. It includes two sets of upper cavity plates 8 and lower cavity plates 40. Two threaded columns 7 are rotatably connected between each set of upper cavity plates 8 and lower cavity plates 40. The upper ends of the two threaded columns 7 extend out of the upper cavity plate 8 and are rotatably connected to the top plate 17. The lower ends of the two threaded columns 7 extend into the lower cavity plate 40. Pulleys 32 are respectively sleeved on the two threaded columns 7 located in the lower cavity plate 40. A transmission belt 26 is sleeved on the outside of the two pulleys 32. A third motor 25 is installed at the bottom of the lower cavity plate 40. The output shaft of the third motor 25 passes through the lower cavity plate 40 and is connected to the bottom end of one of the threaded columns 7. A rectangular frame plate 6 is fixedly installed on the side of the upper cavity plate 8 and the lower cavity plate 40 near the pipeline docking structure. A bidirectional lead screw 22 is provided inside the rectangular frame plate 6. One end of the bidirectional lead screw 22 is connected to the output shaft of the second motor 23 installed on the rectangular frame plate 6. Mounting seats 20 are symmetrically screwed on the bidirectional lead screw 22. A support seat 16 is installed on each mounting seat 20. The side of the support seat 16 that contacts the pipeline is an inclined surface. A limit roller 19 is rotatably connected to the inclined surface. The pipeline is clamped by the inscribed circle formed by the inclined surfaces of the four support seats 16.

[0019] In this embodiment, by adding pipeline auxiliary support structures on both sides of the pipeline docking structure, the movement of the electrical pipeline can be assisted. By starting the second motor 23, the bidirectional lead screw 22 connected to its output shaft is rotated, thereby controlling the two mounting seats 20 on the outer side to move the two corresponding support seats 16 in opposite or opposite directions. Moreover, by starting the third motor 25, in conjunction with the pulley 32 and the transmission belt 26, the two threaded columns 7 rotate synchronously, driving the upper cavity plate 8 on the outer side to move the rectangular frame plate 6 and the support seats 16 downward. In summary, the four limiting rollers 19 on the same side can contact the outer side of the electrical pipeline, thus enhancing the safety of the electrical pipeline and avoiding friction. The pipeline auxiliary support structure has high adjustability and strong adaptability, solving the technical problem that in the actual use of existing electrical pipeline docking auxiliary devices, although they can achieve simple docking assistance functions, the lack of highly adjustable auxiliary support structures and the bending of the pipelines lead to the easy occurrence of breakage, cracking, and scratching of the insulation layer when docking long pipelines, posing a safety hazard of leakage.

[0020] like Figure 4 As shown, the pipeline support structure also includes fixed platforms 21 installed on both sides of the base 1. A fifth hydraulic telescopic rod 33 is installed at the bottom of the fixed platform 21. The upper end of the fifth hydraulic telescopic rod 33 passes through the fixed platform 21 and is fixedly connected to the lower cavity plate 40, which can adjust the overall height of the lower cavity plate 40 and the upper cavity plate 8. In addition, the pipeline support structure also includes a telescopic column 24 installed between the lower cavity plate 40 and the upper cavity plate 8. The telescopic column 24 further improves the stability of the upper cavity plate 8 during the lifting and lowering adjustment process.

[0021] Example 2 Based on Example 1, this example provides a further detailed description of the pipeline connection structure and cleaning structure.

[0022] like Figure 5-9As shown, the pipeline docking structure includes two slidable docking seats 9 mounted on a base 1. Each docking seat 9 consists of two opposing semicircular rings. A connecting plate 34 is installed on one side where the two semicircular rings meet. A third hydraulic telescopic rod 18 is installed between the two corresponding connecting plates 34. Each docking seat 9 is equipped with a cleaning structure. The pipeline docking structure also includes multiple first hydraulic telescopic rods 5 installed axially along the docking seat 9. The output end of each first hydraulic telescopic rod 5 is connected to a pipeline clamp 10, which is located on the inner wall of the docking seat 9.

[0023] The pipeline docking structure also includes a slide rail 12 set in the base 1. The slide rail 12 is provided with a bidirectional threaded rod 2 that is rotatably connected to the base 1. A fourth motor 29 is provided on the inner side of the slide rail 12. The output shaft of the fourth motor 29 is connected to the bidirectional threaded rod 2. Movable seats 4 are symmetrically screwed onto the bidirectional threaded rod 2. The top of each movable seat 4 is fixedly connected to the docking seat 9.

[0024] The cleaning structure includes semi-toothed rings 3 installed on opposite sides of two docking seats 9. Each of the two corresponding semi-toothed rings 3 has an extension plate 11 on its opposite side. A sixth hydraulic telescopic rod 41 connects the extension plate 11 to the semi-toothed rings 3. A second hydraulic telescopic rod 13 and a fourth hydraulic telescopic rod 30 are vertically installed on the extension plate 11. The output ends of both the second and fourth hydraulic telescopic rods 13 and 30 are fixedly connected to mounting heads 35. A built-in cleaning brush 27 is inserted into the lower mounting head 35, and an external cleaning brush 28 is inserted into the upper mounting head 35. A first motor 15 is installed on the top of the docking seat 9. Gears 14 are sleeved on the outer side of the output shaft of the first motor 15, and these gears 14 mesh with the semi-toothed rings 3.

[0025] Among them, a sliding groove 37 is provided on the docking seat 9, and three ball head parts 36 are evenly slidably connected inside the sliding groove 37. One end of the three ball head parts 36 is fixedly connected to a half tooth ring 3.

[0026] The cleaning structure also includes insertion holes 31 on the mounting head 35, the built-in cleaning brush 27 and the external cleaning brush 28. The built-in cleaning brush 27 and the external cleaning brush 28 are connected to the mounting head 35 by the cooperation of the tension spring 39, the insertion rod 38 and the insertion holes 31.

[0027] In this embodiment, the semi-toothed ring 3 and the docking seat 9 are movably connected by a ball head 36 and a sliding groove 37. By adjusting the extension of the third hydraulic telescopic rod 18, the two docking seats 9 are separated, allowing the ball head 36 to slide out from the inside of the sliding groove 37, thus separating the semi-toothed ring 3 from the docking seat 9. This allows for sufficient lubrication of the inside of the sliding groove 37, improving the smoothness of the cleaning structure's rotation. Furthermore, both the built-in cleaning brush 27 and the external cleaning brush 28 are inserted into the mounting head 35. By pulling the insertion rod 38, the tension spring 39 is stretched, allowing one end of the insertion rod 38 to disengage from the inside of the built-in cleaning brush 27 and the external cleaning brush 28, facilitating replacement if the built-in cleaning brush 27 and the external cleaning brush 28 are severely damaged.

[0028] The specific usage method of the above-mentioned electrical wiring connection auxiliary device is as follows: S1. Place the base 1 of this auxiliary device in a suitable working area, and insert one end of each of the two electrical lines into the interior of the pipeline support structure and the pipeline docking structure on both sides respectively. At this time, the built-in cleaning brush 27 is located inside the electrical lines, while the external cleaning brush 28 is located outside the electrical lines. S2. Adjust the fifth hydraulic telescopic rod 33 of the pipeline support structure so that the lower limiting roller 19 contacts the bottom of the electrical pipeline, and at the same time adjust the first hydraulic telescopic rod 5 so that the multiple pipeline clamps 10 fix the electrical pipeline. S3. Start the third motor 25 of the pipeline support structure, and work with the pulley 32 and the transmission belt 26 to make the two threaded columns 7 rotate synchronously, which drives the outer upper cavity plate 8 to drive the upper rectangular frame plate 6 and support seat 16 to move downward, so that the upper limit roller 19 contacts the top of the electrical pipeline, and at this time the length of the telescopic column 24 is shortened. S4. Adjust the second hydraulic telescopic rod 13 to shorten it, which will drive the mounting head 35 connected to its output end to move the built-in dust cleaning brush 27 so that it contacts the inner wall of the electrical conduit. S5. Adjust the extension of the fourth hydraulic telescopic rod 30, which drives the mounting head 35 connected to its output end to move the external cleaning brush 28 so that it contacts the outer wall of the electrical conduit. S6. Start the first motor 15, drive the gear 14 connected to its output shaft to rotate, drive the half gear ring 3 to drive the built-in cleaning brush 27 and the external cleaning brush 28 to rotate, and clean the inner and outer walls of the electrical pipeline respectively. S7. After the cleaning work is completed, adjust the sixth hydraulic telescopic rod 41 to extend it, drive the extension plate 11 to move, so that the built-in cleaning brush 27 and the external cleaning brush 28 are removed from the inside of the electrical pipeline. Then adjust the fourth hydraulic telescopic rod 30 and the second hydraulic telescopic rod 13 again to raise the built-in cleaning brush 27 and the external cleaning brush 28 to the highest position. S8. Start the fourth motor 29, which drives the bidirectional threaded rod 2 connected to its output shaft to rotate, which drives the two movable seats 4 on the outside to move the pipeline docking structure in opposite directions, so that the two electrical pipelines are adjusted to a suitable distance, and the two electrical pipelines are connected and fixed by the pipeline joint.

[0029] When it is necessary to disassemble the semi-toothed ring 3, first adjust the extension of the third hydraulic telescopic rod 18 to separate the two mating seats 9, and then slide the ball head 36 out from the inside of the slide groove 37 to separate the semi-toothed ring 3 from the mating seat 9. When it is necessary to disassemble the built-in cleaning brush 27 and the external cleaning brush 28, first pull the insertion rod 38 to stretch the tension spring 39, so that one end of the insertion rod 38 is disengaged from the inside of the built-in cleaning brush 27 and the external cleaning brush 28, and then move the built-in cleaning brush 27 and the external cleaning brush 28 to separate them from the mounting head 35.
