Description

Technical Field

[0001] This invention belongs to the technical field of power line conduit fixtures, specifically relating to a linear connection tooling for power line conduits. Background Technology

[0002] Electrical conduit is a type of pipe used for laying power lines, primarily for protecting power lines and other communication lines, as well as providing support and fixation. When using electrical conduit, it is usually necessary to connect them to the wires to accommodate different lengths. In practice, this connection is typically done manually. Two sections of conduit are placed at either end, and then one end is pulled manually, or both ends are pulled simultaneously, to bring them closer together for connection. However, due to the weight and smooth surface of the conduit, workers lack a good point of leverage when pulling, making the connection process laborious and inefficient. Therefore, it is essential to provide a simple, rationally designed, automated, efficient, and labor-saving linear connection fixture for electrical conduits. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a linear docking fixture for power line conduits that is simple and reasonable in structure, automatically docks, improves work efficiency, and saves manpower.

[0004] The objective of this invention is achieved as follows: A linear docking fixture for power line conduits includes a frame, a passive docking assembly, and an active docking assembly. A first base is provided on one side of the frame, and the passive docking assembly is mounted on the upper surface of the first base. A base is provided on the left side of the first base, and the first base is slidably connected to the base via a set of slide rail assemblies, enabling the passive docking assembly to move horizontally along the base. A second base is provided on the left side of the base, and an active docking assembly is mounted on the upper surface of the second base. The active docking assembly is movably connected to the passive docking assembly via a set of pull cables, enabling linear docking of the power line conduit body. Clamping and positioning assemblies for clamping and positioning the power line conduit body are provided on the left side of the active docking assembly and the right side of the passive docking assembly.

A second connecting plate is hinged to each of the second T-shaped hinge seats, and the free end of each connecting plate is movably connected to a second arc-shaped groove plate located below the second lug.

[0009] In this invention, the second upper clamp is a semi-circular structure, and the first and second split clamps are both quarter-circular structures. The three together form a complete annular structure, and the two second lugs are symmetrically arranged on both sides of the outer circumference of the second upper clamp. The second T-shaped hinge seats are respectively arranged on the corresponding first and second split clamps.

[0010] Furthermore, a set of arc-shaped clamping plates are provided at intervals on the outer surface of the second upper clamp and the outer surface of the connection between the first split clamp and the second split clamp. A housing positioning cylinder is provided on the outer surface of the second upper clamp and the outer surface of the second split clamp. A T-shaped positioning plate is connected to the output end of the housing positioning cylinder.

[0011] In this invention, the arc-shaped clamping plate is used to install the clamping seat and the locking cylinder; the outer shell positioning cylinder can adjust the position of the T-shaped positioning plate.

[0012] Furthermore, the docking guide device includes an upper ring plate, a first ring plate and a second ring plate located on both sides below the upper ring plate. U-shaped grooves are provided on the upper ring plate and the second ring plate at the corresponding T-shaped positioning plates, and U-shaped positioning plates are installed inside the U-shaped grooves.

[0013] In this invention, the upper ring plate is a semi-circular structure, and the first and second ring plates are both quarter-circular structures, forming a complete circular ring structure. The U-shaped groove and the U-shaped positioning plate are arranged correspondingly above and below, and the space formed by the two is just used to limit the T-shaped positioning plate, which can slide automatically. The overall guiding structure consisting of the card seat, locking cylinder, perforated plate, support plate, guide funnel, and guide pin is respectively arranged on the corresponding upper ring plate and the first ring plate, and is centrally symmetrical about the center of the circle formed by the upper ring plate, the first ring plate, and the second ring plate.

[0014] Furthermore, both the outer surface of the upper ring plate and the outer surface of the first ring plate are provided with perforated plates.

[0018] The beneficial effects of this invention are as follows: This invention is a linear docking fixture for power line conduits. In use, by starting a winch, the winch drives the pulling cable to move. Under the guidance and support of the cable guiding assembly, the pulling cable drives the passive docking assembly to move. The passive docking assembly drives the first base to move, and the first base moves horizontally on the base via the slide rail assembly. This allows the passive docking assembly to slide towards the active docking assembly on the base, achieving automatic docking of the power line conduit body. Then, a clamping assembly or a handheld conduit connection device can be used for locking, improving the docking efficiency of the power line conduit body and saving manpower. After docking is completed, the clamping and positioning assemblies on both sides clamp and position the corresponding power line conduit body, ensuring the stability of the power line conduit body after docking and avoiding the risk of the power line conduit body shaking or even separating due to external forces. This invention has the advantages of simple and reasonable structure, automatic docking operation, improved work efficiency, and manpower saving. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the embodiments and / or accompanying drawings. Example 1

[0030] like Figure 1-9 As shown, a linear docking fixture for power line conduits includes a frame 1, a passive docking assembly 5, and an active docking assembly 7. A first base 2 is provided on one side of the frame 1, and the passive docking assembly 5 is installed on the upper surface of the first base 2. A base 3 is provided on the left side of the first base 2. The first base 2 is slidably connected to the base 3 through a set of slide rail assemblies 4, which enables the passive docking assembly 5 to move horizontally along the base 3. A second base 6 is provided on the left side of the base 3, and the active docking assembly 7 is installed on the upper surface of the second base 6. The active docking assembly 7 is movably connected to the passive docking assembly 5 by a set of pull cables 8, realizing the linear docking operation of the power line conduit body 12. A clamping and positioning assembly 9 for clamping and positioning the power line conduit body 12 is provided on the left side of the active docking assembly 7 and the right side of the passive docking assembly 5. The pull cables 8 passing through the active docking assembly 7 are oriented and guided by the cable guide assembly 10 and then connected to the winch 11.

[0031] The passive docking assembly 5 includes a first upper clamp 51, a first movable clamp 52 and a second movable clamp 53 located on both sides below the first upper clamp 51. A first lug 54 is provided on both sides of the outer periphery of the first upper clamp 51. A first switching hydraulic cylinder 55 is mounted on each of the first lugs 54. A first drive rod 56 is provided at the lower end of each of the first switching hydraulic cylinders 55. The end of the first drive rod 56 is connected to a first T-shaped hinge seat 57 located on the outer periphery of the first movable clamp 52 and the second movable clamp 53, respectively. A first... The connecting plate 58 has its free ends movably connected to the first arc-shaped groove plate 59 located below the first ear seat 54. A support 501 is installed on the outer circumference of the first upper clamp 51 near one of the first ear seats 54. The support 501 has an arc-shaped support groove 502 inside and an L-shaped locking groove 503 on the side. A locking pin 504 is provided in the support groove 502. A locking rod 505 is provided on the outer circumference of the locking pin 504 to lock in conjunction with the L-shaped locking groove 503. The locking pin 504 is connected to the active docking assembly 7 through a pull cable 8.

[0032] In this embodiment, the working principle of the passive docking component is as follows: In actual use, the frame can adopt a freely movable mechanism, such as a caster wheel, etc. The device of the present invention is placed in the power line conduit docking area, and then the two power line conduits to be docked are placed in the passive docking component and the active docking component, which are in the open state, respectively. After placement, the passive docking component and the active docking component are closed to fix the two power line conduits. Then, a winch is used to wind up and pull the cable. After the cable passes through the active docking component, it connects with the passive docking component. Therefore, by pulling the cable, the passive docking component can be driven to move horizontally and stably along the base, so that the two power line conduits approach each other and automatically dock. Then, a clamp component is used to lock the docked power line conduit body, which improves the docking efficiency of the power line conduits and saves manpower. Specifically, since the first ear seats are respectively set on both sides of the first upper clamp, and the first T-shaped hinge seats are respectively installed on the corresponding first movable clamp and second movable clamp, when the first switch hydraulic cylinder is activated, the first switch hydraulic cylinder drives the corresponding first movable clamp and second movable clamp to move outward through the first drive rod and the first T-shaped hinge seat, so that the first movable clamp and the second movable clamp open outward relative to the first upper clamp, and then the power line conduit body can be placed inside. Since the first connecting plate is connected to the first T-shaped hinge seat and the first arc-shaped groove plate at both ends, and the first arc-shaped groove plate is connected to the corresponding first ear seat, the first connecting plate and the first arc-shaped groove plate cooperate with each other to limit the opening and closing range of the first movable clamp and the second movable clamp, and also enable the first movable clamp and the second movable clamp to move under their limited trajectory, ensuring the stability of the movement of the first movable clamp and the second movable clamp. Specifically, a set of supports is arranged symmetrically at the center to ensure the stability of the passive docking assembly when moving on the base, making the docking of the power line conduit more accurate and preventing misalignment. The locking pin is located in the support groove, and the locking rod outside the locking pin is a T-shaped structure. The perpendicular side of this T-shaped structure is an obtuse "V"-shaped bend, which is located in an L-shaped locking groove. During installation, first place the locking pin inside the support groove, then align the bend of the locking rod with the L-shaped locking groove and move it downwards, and then move it to the left side of the L-shaped locking groove to achieve the locking state of the locking rod and the L-shaped locking groove. The locking pin locks one end of the pull cable, and the winch can be used to pull the cable to move the passive docking assembly on the base to realize the docking operation of the power line conduit body.

[0033] The active docking assembly 7 includes an active docking clamp 72 and a control panel 71 installed on the upper part of the active docking clamp 72. The active docking clamp 72 is equipped with a docking guide device 73. A clamping assembly 74 is provided in front of the docking guide device 73. The clamping assembly 74 is used to clamp a group of power line conduit bodies 12 after docking.

[0034] In this embodiment, the opening and closing state of the active docking component or the passive docking component is controlled by the control panel. Of course, in actual use, the control panel can also be installed on the passive docking component for separate control. The active docking clamp and docking guide device are used to clamp the power line conduit body. The clamping component is used to lock the docked power line conduit body.

[0035] The active docking fixture 72 includes a second upper fixture 21, a first split fixture 22 and a second split fixture 23 located on both sides below the second upper fixture 21. The second upper fixture 21, the first split fixture 22 and the second split fixture 23 are all provided with an inner arc plate 24. The inner circumference of the inner arc plate 24 is provided with a pad 25. The outer circumference of the second upper fixture 21 is provided with a second ear seat 26 on both sides. The second ear seat 26 is equipped with a second switch hydraulic cylinder 27. The lower end of the second switch hydraulic cylinder 27 is provided with a second drive rod 28. The end of the second drive rod 28 is connected to a second T-shaped hinge seat 29 located on the outer circumference of the first split fixture 22 and the second split fixture 23 respectively. The second T-shaped hinge seat 29 is hinged with a second connecting plate 201. The free end of the second connecting plate 201 is movably connected to a second arc-shaped groove plate 202 located below the second ear seat 26 respectively.

[0036] In this embodiment, the working principle of the active docking component is as follows: the power line conduits to be docked are placed in the active docking component in the open state. After placement, the active docking component is closed to fix the two power line conduits. Then, a winch is used to wind up and pull the cable. After the cable passes through the active docking component, it connects with the passive docking component. Therefore, by pulling the cable, the passive docking component can be moved horizontally and stably along the base, so that the two power line conduits approach each other and automatically dock. Then, a clamp component is used to lock the docked power line conduit body, which improves the docking efficiency of the power line conduits and saves manpower. Since the second ear seats are respectively located on both sides of the second upper clamp, and the second T-shaped hinge seats are respectively installed on the corresponding first split clamp and second split clamp, when the second switch hydraulic cylinder is activated, the second switch hydraulic cylinder drives the corresponding first split clamp and second split clamp to move outward through the second drive rod and the second T-shaped hinge seat, so that the first split clamp and the second split clamp open outward relative to the second upper clamp, and then the power line conduit body can be placed inside. Since the two ends of the second connecting plate are respectively connected to the second T-shaped hinge seat and the second arc-shaped groove plate, and the second arc-shaped groove plate is connected to the corresponding second ear seat, the second connecting plate and the second arc-shaped groove plate cooperate with each other to limit the opening and closing range of the first split clamp and the second split clamp, and also enable the first split clamp and the second split clamp to move within their limited trajectory, ensuring the stability of the movement of the first split clamp and the second split clamp.

[0037] A set of arc-shaped clamping plates 203 are provided at intervals on the outer surface of the second upper clamp 21 and the outer surface of the connection between the first split clamp 22 and the second split clamp 23. A housing positioning cylinder 204 is provided on the outer surface of the second upper clamp 21 and the outer surface of the second split clamp 23. The output end of the housing positioning cylinder 204 is connected to a T-shaped positioning plate 205.

[0038] In this embodiment, the inner arc plates are respectively installed inside the corresponding second upper half clamp, the first split clamp and the second split clamp, while the pads are respectively installed inside the corresponding inner arc plates, which play a protective role for the power line conduit body; the outer shell positioning cylinder adjusts the position of the T-shaped positioning plate so that the T-shaped positioning plate corresponds to the corresponding U-shaped groove, which facilitates the quick insertion and cooperation of the active docking clamp and the docking guide device.

[0039] The docking guide device 73 includes an upper ring plate 31, a first ring plate 32 and a second ring plate 33 located on both sides below the upper ring plate 31. U-shaped grooves 34 are provided on the upper ring plate 31 and the second ring plate 33 at the corresponding T-shaped positioning plates 205. U-shaped positioning plates 35 are installed inside the U-shaped grooves 34.

[0040] Both the outer surface of the upper ring plate 31 and the outer surface of the first ring plate 32 are provided with perforated plates 38. The perforated plates 38 are connected to the output end of the locking cylinder 37. The locking cylinder 37 is clamped in the arc-shaped clamping plate 203 by the clamping seat 36. Each perforated plate 38 is equipped with a support plate 39. Each support plate 39 is equipped with a guide funnel 301 corresponding to one end of the perforated plate 38. Each guide funnel 301 is provided with a guide pin 302 on the left side. The guide funnel 301 and the guide pin 302 are used to pull the cable 8 through, so that one end of the cable 8 is connected to the locking pin 504 and the other end is connected to the winch 11 after passing through the cable guide assembly 10.

[0041] In this embodiment, the overall guiding structure consisting of the card holder, locking cylinder, perforated plate, support plate, guide funnel, and guide pin is centrally symmetrically arranged. This is to ensure the pulled cable remains horizontally aligned, preventing bending and ensuring the stability of the passive docking assembly as it moves on the base. This makes the docking of the power line conduit more accurate and prevents misalignment. The guide funnel and guide pin are both located on the support plate, and the card holder is located inside the arc-shaped card plate. When the T-shaped positioning plate aligns with the U-shaped groove, the locking cylinder drives the U-shaped groove of the docking guide device to move along the T-shaped positioning plate, causing the guide ring structure consisting of the upper ring plate, first ring plate, and second ring plate to insert into the active docking fixture, completing the docking operation. Furthermore, in actual use… During use, the T-shaped positioning plate can be finely adjusted by the positioning cylinder on the outer shell. Then, the position of the card seat and locking cylinder can be finely adjusted within the arc-shaped card plate. This ensures that the pull cable, after passing through the guide funnel and guide pin and being fixedly connected to the locking pin, is in a taut and horizontal state, guaranteeing stable and reliable power line conduit docking operation. The docking guide device, on the one hand, cooperates with the active docking clamp to guide the pull cable and ensure that the pull cable is in a good horizontal state. On the other hand, after the docking guide device and the active docking clamp are fitted together, their end faces are flush. When the clamp assembly is used to lock the power line conduit after docking, it can prevent the clamp assembly from locking the active docking clamp or the docking guide device's redundant structure.

[0042] As one feasible implementation, the specific structure of the clamp assembly is as follows: the clamp assembly includes a split clamp device, and the upper and lower ends of the split clamp device are connected by fastening screws. A pressure test interface seat is installed on the outer peripheral surface of one of the clamp devices, and a pressure test interface connector is connected to the pressure test interface seat.

[0043] Specifically, after the power line conduit body is connected, a split clamp device is fitted onto the outside of the power line conduit body and locked with fastening screws. Then, the pressure test interface connector is connected to the pressure test device to conduct a pressure test and verify the actual effect of the connection.

[0044] This invention relates to a linear docking fixture for power line conduits. In use, the invention activates a winch 11, which drives a pulling cable 8. Under the guidance and support of a cable guide assembly 10, the pulling cable 8 moves a passive docking assembly 5. The passive docking assembly 5 then moves a first base 2. The first base 2 moves horizontally on a base 3 via a slide rail assembly 4, allowing the passive docking assembly 5 to slide towards an active docking assembly 7 on the base 3. This achieves automatic docking of the power line conduit body 12. A clamp assembly 74 can then be used for locking, improving the docking efficiency of the power line conduit body 12 and saving manpower. After docking, the clamping and positioning assemblies 9 on both sides clamp and position the corresponding power line conduit body 12, ensuring stability after docking and preventing the power line conduit body 12 from shaking or even separating due to external forces. This invention has the advantages of simple and reasonable structure, automatic docking operation, improved work efficiency, and manpower saving. Example 2

[0045] like Figure 1-9 As shown, a linear docking fixture for power line conduits includes a frame 1, a passive docking assembly 5, and an active docking assembly 7. A first base 2 is provided on one side of the frame 1, and the passive docking assembly 5 is installed on the upper surface of the first base 2. A base 3 is provided on the left side of the first base 2. The first base 2 is slidably connected to the base 3 through a set of slide rail assemblies 4, which enables the passive docking assembly 5 to move horizontally along the base 3. A second base 6 is provided on the left side of the base 3, and the active docking assembly 7 is installed on the upper surface of the second base 6. The active docking assembly 7 is movably connected to the passive docking assembly 5 by a set of pull cables 8, realizing the linear docking operation of the power line conduit body 12. A clamping and positioning assembly 9 for clamping and positioning the power line conduit body 12 is provided on the left side of the active docking assembly 7 and the right side of the passive docking assembly 5. The pull cables 8 passing through the active docking assembly 7 are oriented and guided by the cable guide assembly 10 and then connected to the winch 11.

[0046] The cable guiding assembly 10 includes a guide frame 101, with a through-hole frame 102 inside the guide frame 101. A first guide wheel device 103 is provided on the upper right side of the guide frame 101, and a second guide wheel device 104 is provided on the bottom left side.

[0047] In this embodiment, one end of the pull cable is fixedly connected to the locking pin, and the other end passes through the through hole of the perforated plate, the guide funnel and the guide pin, then passes through the first guide wheel device, then through the through hole frame and the second guide wheel device before being connected to the winch.

[0048] The winch 11 uses a reduction drive device 1101 as its power source. The winch 11 has a winch drum 1102 that is powered by the reduction drive device 1101. A limit frame 1103 is provided in front of the winch 11. The winch drum 1102 is connected to the pull cable 8 by a connecting buckle 1104.

[0049] In this embodiment, the pull cable after passing through the cable guide assembly is connected to the connecting buckle. There are two connecting buckles, which can realize the winding and anti-winding operations of two sets of pull cables at the same time. Moreover, the limiting frame restricts the connecting buckle to prevent it from passing through the opening of the limiting frame, and to prevent the winch drum from over-winding the cable, thereby avoiding damage to the pull cable, active docking assembly, passive docking assembly and other structures.

[0050] The clamping and positioning assembly 9 includes a telescopic cylinder assembly 91. A lifting plate 92 is provided at the upper end of the telescopic cylinder assembly 91. A lower pressure plate 93 is provided on both sides of the lower surface of the lifting plate 92. A semi-circular groove extending along its length is provided on the lower pressure plate 93, and the semi-circular groove is adapted to the power line conduit body. A set of support seats 94 is provided at intervals in front of the telescopic cylinder assembly 91. A Y-shaped positioning seat 95 is provided behind the support seats 94 corresponding to the lower pressure plate 93.

[0051] In this embodiment, when the power line conduit body is docked and locked using a clamp assembly, or when the power line conduit body is docked and accurately docked, a clamping and positioning assembly can be used to reliably clamp the power line conduit body to prevent relative movement, shaking, or breakage, which could lead to docking failure. Specifically, the telescopic cylinder assembly is activated, which drives the lifting plate to move up and down. When the telescopic cylinder assembly drives the lifting plate to move down, the lifting plate will drive the lower pressure plate to move down. The lower pressure plate cooperates with the Y-shaped positioning seat to effectively clamp the power line conduit body located between the lower pressure plate and the Y-shaped positioning seat, ensuring stability and reliability during the overall docking process.

[0052] As another feasible implementation, a handheld cable connector can be used instead of the clamp assembly. The structure of the handheld cable connector is as follows: The handheld cable connector includes a handheld frame, and clamping claws are movably installed on the left and right sides of the lower part of the handheld frame via pivot pins. An arc-shaped clamping plate is fixedly or detachably installed on the inner side of the clamping claws. A connecting frame is provided inside the handheld frame, and opening and closing plates are movably installed on the lower sides of the connecting frame. The lower ends of the opening and closing plates are respectively connected to the corresponding clamping claws, and the upper end of the connecting frame is poweredly connected to the linear drive device. Specifically, after the power line conduit body is connected, the clamping plate is placed at the connection point of the connected conduit body. Then, the linear drive device is activated. The linear drive device drives the opening and closing plate through the connecting frame. The opening and closing plate drives the clamping claw to rotate around the pivot pin, thereby opening the clamping plate and placing it at the connection point of the power line conduit body. Closing the clamping plate achieves effective clamping of the power line conduit body. When the clamping claw and the arc-shaped clamping plate are fixedly connected, it is only necessary to adjust the force of the linear drive device to ensure that the clamping plate is tightly clamped to the outside of the power line conduit body. Further, the clamping claw can be connected by fixing bolts or... Clamping plate; When the clamping claws and the arc-shaped clamping plate are connected in a separate manner (e.g., using magnetic attraction, snap-fit, adhesive, sliding groove engagement, or other separable connection methods), the clamping plate is tightly clamped to the outside of the power line conduit body by a linear drive device. Then, the upper and lower mating ends of the clamping plate are connected by fixing bolts (similar to the fixing connection operation of the clamp connection end) to lock it to the outside of the power line conduit body. Then, the clamping claws are separated from the clamping plate, and the hand-held conduit connection device is removed, leaving only the clamping plate effectively clamped and fixed to the outside of the power line conduit body.

[0053] This invention relates to a linear docking fixture for power line conduits. In use, the invention activates a winch 11, which drives a pulling cable 8. Under the guidance and support of a cable guide assembly 10, the pulling cable 8 moves a passive docking assembly 5. The passive docking assembly 5 moves a first base 2, which moves horizontally on a base 3 via a slide rail assembly 4. This allows the passive docking assembly 5 to slide towards an active docking assembly 7 on the base 3, automatically docking the power line conduit body 12. A handheld conduit connection device 84 can then be used for locking, improving the docking efficiency of the power line conduit body 12 and saving manpower. After docking, the clamping and positioning assemblies 9 on both sides clamp and position the corresponding power line conduit body 12, ensuring stability after docking and preventing the power line conduit body 12 from shaking or even separating due to external forces. This invention has the advantages of simple and reasonable structure, automatic docking operation, improved work efficiency, and manpower saving.
