Description

Technical Field

[0001] This application belongs to the field of power emergency repair tower hardware / equipment, specifically relating to an emergency tower conductor suspension device. Background Technology

[0002] Emergency repair towers: Emergency repair towers are temporary replacement towers designed for high-voltage transmission lines damaged by icing, storms, foundation subsidence, external forces, etc. Conductor suspension requires additional hardware installed on the crossarm side as a suspension mechanism.

[0003] In emergency repair operations, the time spent on fitting installation and wire hanging accounts for a large proportion, so a device for quickly hanging wires is needed.

[0004] In the 220kV four-split conductor V-type insulator string replacement tool disclosed in Chinese utility model CN208401405U, the lower part of the tool has an insulated four-wire hook with angle steel clamps symmetrically mounted on two straight lead screws. This four-wire hook structure can be used for quickly suspending emergency tower conductors. Utility Model Content

[0005] Technical problem: The technical problem to be solved by this application is to further optimize the structure of the "clamp" part and improve the efficiency of the hoisting operation.

[0006] Technical solution:

[0007] An emergency tower conductor suspension device includes at least one hook, and a fastening mechanism is provided on one side of the hook. The fastening mechanism includes:

[0008] A fixing base is fixed to the hook mounting side. The fixing base is provided with a first hinge hole and a second junction hole. The horizontal position of the first hinge hole is higher than that of the second hinge hole, and it is farther away from the mounting side of the hook than the second hinge hole.

[0009] The clamping assembly has its front end connected to the first hinge hole and its end connected to a pressure plate facing the inside of the hook. By rotating the clamping assembly around the hinge axis, the pressure plate can be adjusted to move closer to or further away from the inside of the hook, thereby constraining the wires suspended inside the hook.

[0010] A push rod, the end of which is hinged to the second hinge hole;

[0011] The support rod has its front end hinged to the push rod near the middle, and its end hinged to the clamping assembly near the middle. By pushing the push rod, the support rod presses the pressure plate on the clamping assembly against the wire inside the hook, thus quickly completing the wire hanging.

[0012] Furthermore, the clamping assembly includes a connecting rod, the front end of which intersects with a first hinge hole, and its end is provided with a threaded hole. An adjusting screw is provided on the threaded hole, and a pressure plate is provided at the bottom of the adjusting screw. The end of a support rod intersects with the middle of the connecting rod. A push rod drives the support rod, which in turn drives the connecting rod to press down on the pressure plate for the first tightening, and then the adjusting screw is used for a second tightening adjustment.

[0013] Furthermore, all hinge axes of the connecting rod, push rod, and support rod are parallel to each other, and the threaded holes are perpendicular to any one of the hinge axes. That is, their hinge rotations belong to the same rotation plane or mutually parallel rotation planes.

[0014] Furthermore, the pressure plate is an arc-shaped plate, which can better fit the outer wall of the wire and achieve a better wrapping and pressing effect. Its middle part is sleeved on the end of the adjusting screw, which can rotate relative to the pressure plate. That is, the two are movably connected, and when the adjusting screw is rotated for longitudinal adjustment, the pressure plate does not rotate with the adjusting screw.

[0015] Furthermore, the device also includes a symmetrical main body with two upward-facing hooks symmetrically arranged at both ends and a hanging connection seat in the middle. The main body is a four-line hook with an upper hook.

[0016] Furthermore, a portion extends below the hook on the main body to serve as a connecting plate, on which a hanging rod is suspended. The bottom end of the hanging rod is also equipped with a hook.

[0017] Furthermore, on the basic structure of the above four-line hook, the two sides of the hook are the connecting side and the mounting side, respectively. The connecting side is used to connect the main body or the hanging rod, and the mounting side is located on the outside of the hook. Its side wall is provided with mounting holes for connecting the fixing seat.

[0018] Furthermore, the first hinge hole on the mounting base is positioned higher than the highest point on the hook mounting side. Sufficient allowance is provided for the connecting rod to rotate around its axis to avoid mechanical interference.

[0019] The beneficial effects of this application are as follows:

[0020] 1. Traditional hardware installation and conductor suspension are time-consuming. This device achieves rapid pressing and tightening through the linkage mechanism of the push rod, support rod, and clamping assembly. Pushing the push rod will drive the support rod to apply pressure to the inside of the conductor with the pressure plate, completing the initial constraint. This significantly shortens the operation time in emergency repairs and is suitable for urgent scenarios involving high-voltage lines.

[0021] 2. Further, a dual-fastening adjustment is introduced: first, mechanical pressing is performed through the push rod-support rod system (first-level fastening), and then fine longitudinal adjustment is performed using the adjusting screw (second-level fastening). This avoids the limitations of a single mechanism and improves the overall operation speed. Furthermore, adjusting the screw raises the height of the connecting rod end, causing the lower end of the support rod to also rise slightly, effectively limiting the position of the push rod and preventing the push rod from slipping and causing fastening failure.

[0022] 3. The design of the fastening mechanism (such as the first hinge hole of the fixing seat being higher than the second hinge hole and farther away from the hook mounting side) ensures that there is sufficient margin when the clamping assembly rotates around the shaft, avoiding mechanical interference or jamming, and improving the reliability and durability of the device.

[0023] 4. All hinge shafts are parallel to each other, and the threaded holes are perpendicular to the hinge shafts, ensuring that rotation is in the same plane or parallel plane, reducing friction and wear, and lowering the risk of failure during operation.

[0024] 5. The pressure plate features an arc-shaped design, which better fits the outer wall of the wire, providing a wrapping and clamping effect to prevent the wire from slipping or being damaged. Simultaneously, the pressure plate is movably connected to the adjusting screw (the pressure plate does not rotate with the screw), ensuring a smooth adjustment process and avoiding additional torsional damage to the wire.

[0025] 6. The device includes a symmetrical main body (similar to the upper hook of a four-line hook), with upward hooks at both ends and a hanging connection seat in the middle, which facilitates the simultaneous handling of multiple conductors (such as four-split conductors) and is suitable for three-phase or multi-phase power systems.

[0026] 7. An extension plate extends below the hook to hang a hanging rod (hook is also provided at the bottom), enabling vertical expansion, supporting more complex hanging configurations, and improving the versatility of the device.

[0027] 8. The clamping structure of existing tools (such as CN208401405U) has been optimized, and the functionality has been improved by using only simple mechanical components (fixed seat, clamping assembly, push rod, support rod).

[0028] The beneficial effects of this application focus on solving the problem of time-consuming installation of hardware mentioned in the background technology. Through mechanical linkage and multiple adjustment mechanisms, it achieves fast, safe and efficient wire hanging, which is suitable for the timeliness requirements of power emergency repair.

[0040] like Figure 1-3 As shown, an emergency tower conductor suspension device includes a hook 1, and a fastening mechanism is provided on one side of the hook 1. The fastening mechanism includes:

[0041] A fixing base 2 is fixed to the mounting side of the hook 1. The fixing base 2 is provided with a first hinge hole 3 and a second junction hole. The horizontal position of the first hinge hole 3 is higher than that of the second hinge hole 4, and the position of the first hinge hole 3 is higher than the highest point of the mounting side of the hook 1. Sufficient allowance is provided for the connecting rod 9 to rotate around the axis to avoid mechanical interference; and it is farther away from the mounting side of the hook 1 than the second hinge hole 4.

[0042] Reference Figure 3In this embodiment, the fixed part is hollow as a whole, and a part of its left side is perpendicular to the main board 5, serving as a connecting seat 6. The connecting seat 6 is symmetrically arranged on both sides, and two connecting holes 7 are provided on each side for connecting to the mounting holes 18 on the mounting side of the hook 1. The first hinge hole 3 is located at the upper left corner of the main board 5, and the second hinge hole 4 is located on the right side and is lower than the first hinge hole 3.

[0043] The clamping assembly has its front end connected to the first hinge hole 3 and its end connected to the pressure plate 8 facing the inside of the hook 1. By rotating the clamping assembly around the hinge axis, the pressure plate 8 can be adjusted to move closer to or further away from the inside of the hook 1, thereby constraining the wire suspended inside the hook 1.

[0044] The clamping assembly includes a connecting rod 9, the front end of which intersects with the first hinge hole 3 and is located inside the hollow cavity of the fixed base 2 (the other hinge positions are not described, but are shown in the attached drawings). Its end has a threaded hole 10, and an adjusting screw 11 is mounted on the threaded hole 10. A pressure plate 8 is mounted at the bottom of the adjusting screw 11. The front end of the support rod 12 is hinged to the push rod 13 near the middle, and the end of the support rod 12 intersects with the middle of the connecting rod 9. The end of the push rod 13 is hinged to the second hinge hole 4 and is located on the outer sides of both sides of the fixed base 2. By pushing the push rod 13, the support rod 12 presses the pressure plate 8 on the clamping assembly against the wire inside the hook 1, thus quickly completing the wire hanging.

[0045] The push rod 13 drives the support rod 12, which in turn drives the connecting rod 9 to press down the pressure plate 8 for the first tightening, and then the adjusting screw 11 is used for the second tightening adjustment.

[0046] The pressure plate 8 is an arc-shaped plate, which can better fit the outer wall of the wire and achieve a better wrapping and pressing effect. Its middle part is sleeved on the end of the adjusting screw 11, and the adjusting screw 11 can rotate relative to the pressure plate 8. That is, the two are movably connected. When the adjusting screw 11 is rotated for longitudinal adjustment, the pressure plate 8 does not need to rotate with the adjusting screw 11.

[0047] All hinge axes of connecting rod 9, push rod 13, and support rod 12 are parallel to each other, and threaded hole 10 is perpendicular to any one of the hinge axes. That is, their hinge rotations belong to the same rotation plane or mutually parallel rotation planes.

[0048] Its fastening principle is referenced Figure 4 In the figure, the purple circle represents the motion trajectory of the red push rod 13 (model I), the black circle represents the motion trajectory of the green connecting rod 9 (model II), the blue line represents the support rod 12 (model III) hinged to the connecting rod 9 and the push rod 13, and the upper and lower horizontal lines l1 and l2 are the horizontal reference lines for the positions of the first hinge hole 3 and the second hinge hole 4, respectively.

[0049] In Figure a, the connecting rod 9 drives the pressure plate 8 to completely disengage from the hook 1. As the push rod 13 rotates to the right, it drives the connecting rod 9 to rotate to the right. In state b, the support rod 12 and the push rod 13 are collinear, and the end of the connecting rod 9 is at its lowest point. When the push rod 13 continues to run to state c, the end of the connecting rod 9 returns slightly to the horizontal line, becoming level or almost level. At this time, the conductor generates an upward rebound force on the pressure plate 8, causing the connecting rod 9 to have a tendency to rotate. This, in turn, drives the support rod 12 to push the push rod 13 in the opposite direction, preventing the push rod 13 from resetting and causing the fastening to fail. If the rebound force is insufficient, the adjusting screw 11 can be adjusted to make the pressure plate 8 move downward, which can also make the connecting rod 9 rotate, thus achieving the above-mentioned locking function.

[0050] The device also includes a symmetrical main body 14, with two upward-facing hooks 1 symmetrically arranged at both ends of the main body 14, and a hanging connection seat 15 located in the middle of the main body 14. That is, the main body 14 is the upper hook 1 of the four-line hook. The hanging connection seat 15 is used to attach the four-line hook to the emergency tower.

[0051] Reference Figure 5 A portion of the hook 1 on the main body 14 extends below to form a connecting plate 16. A hanging rod 17 is suspended from the connecting plate 16, and a hook 1 is also provided at the bottom end of the hanging rod 17. On the basic structure of the above four-line hook, the two sides of the hook 1 are the connecting side and the mounting side, respectively. The connecting side is used to connect the main body 14 or the hanging rod 17, and the mounting side is located on the outside of the hook 1. Its side wall is provided with a mounting hole 18, which is used to connect the fixing base 2.
