Description

Technical Field

[0001] This invention relates to the field of power facility protection technology, specifically to a device for preventing external damage during the construction of power transmission lines. Background Technology

[0002] The power line construction protection device is a comprehensive protection system that uses a combination of "physical isolation + intelligent monitoring + real-time response" to minimize the risk of line damage caused by human, mechanical or environmental factors during construction, thus ensuring the safety and progress of power grid construction.

[0003] Utility poles are used to support power lines. If the poles are installed directly by burying them, in areas with strong winds, the top of the pole is prone to swaying, causing a gap between the bottom of the pole and the ground, resulting in lateral tilting or even toppling, which affects the subsequent support of the power lines.

[0004] To address the above problems, a device for preventing external damage during the construction of power transmission lines is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a device for preventing external damage during the construction of power transmission lines. By using this device, the problems mentioned in the background can be solved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for preventing external damage during the construction of power transmission lines, comprising a mounting base, a utility pole disposed in the inner cavity of the mounting base, a fixing base disposed in the inner cavity of the mounting base, the utility pole being located at the top of the fixing base, a fixing component disposed in the inner cavity of the fixing base, two fixing rings disposed near the top of the utility pole on the outer periphery, connecting plates disposed on the opposite side of the fixing rings near both sides, protective components disposed on the top of the fixing base near both sides, and anti-tilting components disposed on the protective components.

[0007] The fixing assembly includes a hydraulic rod fixedly installed at the top center of the inner cavity of the fixing base. A movable block is fixedly installed at the bottom end of the hydraulic rod. A hinge rod is hinged to the bottom of the movable block near both sides. An L-shaped rack plate is hinged to the opposite end of the hinge rod. The bottom of the L-shaped rack plate is slidably connected to the bottom of the inner cavity of the fixing base. A rotating gear is engaged at the top of the L-shaped rack plate. A drive handle is fixedly installed near the top of the front side of the rotating gear. A fixing frame is provided on the front side of the rotating gear. The front end of the drive handle moves through the inner cavity of the fixing frame. An L-shaped block is fixedly installed at the top of the fixing frame. The top of the L-shaped block moves through the inner cavity of the fixing base and is fixedly installed with an arc-shaped clamp plate. The arc-shaped clamp plate is fitted against the outer periphery of the utility pole.

[0008] Furthermore, a fixed shaft is fixedly installed on the rear side of each of the rotating gears, and the rear end of the fixed shaft is rotatably connected to the rear side of the inner cavity of the fixed seat.

[0009] Furthermore, limiting telescopic rods are fixedly installed on the opposite side of the fixed frame near the top and bottom, and the opposite ends of the limiting telescopic rods are fixedly connected to the inner cavity sidewall of the fixed seat.

[0010] Furthermore, the anti-tilt assembly includes a connecting box fixedly installed on the opposite side of the fixing ring and the fixing seat. A round rod is rotatably connected to the rear side of the inner cavity of the connecting box, and the front end of the round rod passes through the inner cavity of the connecting box. A drive disk is fixedly installed at the front end of the bottom round rod. A rotating roller is fixedly sleeved on the outer circumference of the round rod. A connecting rope is wound around the outer circumference of the bottom rotating roller, and one end of the connecting rope movably passes through the inner cavity of the two connecting boxes and is fixedly connected to the adjacent rotating roller.

[0011] Furthermore, a torsion spring is movably sleeved on the outer periphery of the top circular rod near the front end, and the two ends of the torsion spring are fixedly connected to the front side of the inner cavity of the connecting box and the outer periphery of the circular rod, respectively.

[0012] Furthermore, a T-shaped rod is movably inserted through the front side of the drive disk near the top, and several limiting holes are opened on the front side of the adjacent connecting box. The rear end of the T-shaped rod is movably inserted into the inner cavity of the adjacent limiting hole. A return spring is movably sleeved on the outer periphery of the T-shaped rod near the front end, and the two ends of the return spring are fixedly connected to the drive disk and the T-shaped rod respectively.

[0013] Furthermore, two dampers are fixedly installed on opposite sides of the mounting base and the fixed base. Each damper has a damping spring movably sleeved on its outer periphery, and the two ends of the damping spring are fixedly connected to the mounting base and the fixed base, respectively.

[0014] Furthermore, the protective assembly includes an L-shaped frame located near one side of the top of the fixed base. A fixed plate is fixedly installed on the other side of the L-shaped frame near both the front and rear sides. A connecting telescopic rod is fixedly installed on the front side of the rear fixed plate near both sides. A compression plate is fixedly installed at the ends of the connecting telescopic rods. A connecting spring is movably sleeved on the outer periphery of the connecting telescopic rods, and the two ends of the connecting spring are fixedly connected to the adjacent fixed plate and the compression plate, respectively.

[0016] Furthermore, a limiting block is fixedly installed at the bottom of the lead screw nut, and a limiting rod is movably passed through the front side of the limiting block, with both ends of the limiting rod being fixedly connected to the adjacent connecting frame respectively.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] When fixing the utility pole, the fixing components work together to move the two L-shaped rack plates to opposite sides, and the drive handle and fixing frame work together to move the two arc-shaped clamps to opposite sides, thus fixing the utility pole and improving the stability of the installation.

[0019] When stabilizing the utility pole laterally, the anti-tilt component, when used in conjunction with the anti-tilt device, can wind the connecting rope around the outer circumference of the bottom rotating roller, generating tension in the connecting rope. This allows for lateral traction on the utility pole, improving its stability and preventing it from tipping over.

[0020] When the connecting rope breaks, the upper part can be wound up around the outer circumference of the adjacent rotating roller with the help of the torsion spring. With the help of the protective components, the lower part of the connecting rope can be limited to prevent the rope from swinging due to breakage and causing injury to others.

Therefore, they should not be construed as limitations on this invention.

[0032] Example 1: As Figure 1 - Figure 8 A device for preventing external damage during the construction of power transmission lines includes a mounting base 1, a utility pole 3 installed in the inner cavity of the mounting base 1, a fixing base 2 installed in the inner cavity of the mounting base 1, the utility pole 3 located at the top of the fixing base 2, a fixing component 8 installed in the inner cavity of the fixing base 2, two fixing rings 4 installed on the outer periphery of the utility pole 3 near the top, connecting plates 5 installed on the opposite side of the fixing rings 4 near both sides, protective components 7 installed on the top of the fixing base 2 near both sides, and anti-tilting components 6 installed on each of the protective components 7.

[0033] The fixing component 8 includes a hydraulic rod 81 fixedly installed at the middle position of the top of the inner cavity of the fixing base 2. A movable block 82 is fixedly installed at the bottom end of the hydraulic rod 81. A hinge rod 83 is hinged to the bottom of the movable block 82 near both sides. An L-shaped rack plate 84 is hinged to the opposite end of the hinge rod 83. The bottom of the L-shaped rack plate 84 is slidably connected to the bottom of the inner cavity of the fixing base 2. A rotating gear 85 is meshed at the top of the L-shaped rack plate 84. A drive handle 86 is fixedly installed near the top of the front side of the rotating gear 85. A fixing frame 87 is provided on the front side of the rotating gear 85. The front end of the drive handle 86 moves through the inner cavity of the fixing frame 87. An L-shaped block 88 is fixedly installed at the top of the fixing frame 87. The top of the L-shaped block 88 moves through the inner cavity of the fixing base 2 and is fixedly installed with an arc-shaped clamp 89. The arc-shaped clamp 89 is fitted to the outer periphery of the utility pole 3.

[0034] Specifically, when fixing the utility pole 3, the two L-shaped rack plates 84 can be moved to opposite sides when used in conjunction with the fixing component 8, and the two arc-shaped clamps 89 can be moved to opposite sides when used in conjunction with the drive handle 86 and the fixing frame 87, thereby fixing the utility pole 3 and improving the stability of the installation of the utility pole 3.

[0035] Each of the rotating gears 85 has a fixed shaft 851 fixedly installed on its rear side, and the rear end of the fixed shaft 851 is rotatably connected to the rear side of the inner cavity of the fixed seat 2.

[0036] Specifically, by setting a fixed shaft 851, the rotating gear 85 can be supported, thereby improving the stability of the rotating gear 85 during operation.

[0037] On the opposite side of the fixed frame 87, near the top and bottom, a limiting telescopic rod 871 is fixedly installed, and the opposite end of the limiting telescopic rod 871 is fixedly connected to the inner cavity side wall of the fixed seat 2.

[0038] Specifically, by setting the limiting telescopic rod 871, the movement of the fixed frame 87 can be limited, thereby improving the stability of the movement of the fixed frame 87.

[0039] The anti-tilt assembly 6 includes a connecting box 61 fixedly installed on the opposite side of the fixing ring 4 and the fixing seat 2. (A rectangular opening A is opened on the opposite side of the connecting box 61, and the connecting rope 65 passes through the inner cavity of the rectangular opening A.) A round rod 62 is rotatably connected to the rear side of the inner cavity of the connecting box 61, and the front end of the round rod 62 passes through the inner cavity of the connecting box 61. A drive disk 64 is fixedly installed at the front end of the bottom round rod 62. A rotating roller 63 is fixedly sleeved on the outer circumference of the round rod 62. A connecting rope 65 is wound around the outer circumference of the bottom rotating roller 63, and one end of the connecting rope 65 movably passes through the inner cavity of the two connecting boxes 61 and is fixedly connected to the adjacent rotating roller 63.

[0040] Specifically, when stabilizing the utility pole 3 laterally, with the cooperation of the anti-tilt component 6, the connecting rope 65 can be wound around the outer periphery of the bottom rotating roller 63, which can generate tension in the connecting rope 65, thereby pulling the utility pole 3 laterally and improving the fixing effect of the utility pole 3, thus preventing it from tipping over.

[0041] A torsion spring 621 is movably sleeved on the outer periphery of the top round rod 62 near the front end, and the two ends of the torsion spring 621 are fixedly connected to the front side of the inner cavity of the connecting box 61 and the outer periphery of the round rod 62, respectively.

[0042] Specifically, by setting a torsion spring 621, when the connecting rope 65 breaks, the torsion spring 621 returns to its initial state, thereby enabling the adjacent round rod 62 to rotate, which in turn can wind up the connecting rope 65, prevent it from swinging, and improve its safety in use.

[0043] A T-shaped rod 641 is movably inserted through the front side of the drive disc 64 near the top. Several limiting holes 643 are opened on the front side of the adjacent connecting box 61, and the rear end of the T-shaped rod 641 is movably inserted into the inner cavity of the adjacent limiting hole 643. A return spring 642 is movably sleeved on the outer periphery of the T-shaped rod 641 near the front end, and the two ends of the return spring 642 are fixedly connected to the drive disc 64 and the T-shaped rod 641 respectively.

[0044] Specifically, by setting a T-shaped rod 641 to be inserted into the inner cavity of the adjacent limiting hole 643, the position of the drive disc 64 after it moves can be limited, and the connecting rope 65 can be kept taut.

[0045] Two dampers 11 are fixedly installed on opposite sides of the mounting base 1 and the fixed base 2. Each damper 11 is movably fitted with a damping spring 12 on its outer periphery, and the two ends of the damping spring 12 are fixedly connected to the mounting base 1 and the fixed base 2 respectively.

[0046] Specifically, by setting up damper 11 and damping spring 12, the sway of the utility pole 3 can be prevented from being too strong, thus extending its service life.

[0047] The protective component 7 includes an L-shaped frame 71 located on the top of the fixed base 2 near one side. A fixed plate 72 is fixedly installed on the other side of the L-shaped frame 71 near both the front and rear sides. A connecting telescopic rod 73 is fixedly installed on the front side of the rear fixed plate 72 near both sides. A compression plate 75 is fixedly installed at the ends of the connecting telescopic rod 73. A connecting spring 74 is movably sleeved on the outer periphery of the connecting telescopic rod 73. The two ends of the connecting spring 74 are fixedly connected to the adjacent fixed plate 72 and the compression plate 75 respectively. Several rubber blocks 76 are fixedly installed on the opposite side of the adjacent fixed plate 72 and the compression plate 75.

[0048] Specifically, by setting the connecting spring 74, rubber block 76, and fixing plate 72, the lower half of the connecting rope 65 can be limited to prevent it from shaking when it breaks.

[0049] Connecting frames 711 are provided on both the front and rear sides of the L-shaped frame 71, and the connecting frames 711 are fixedly connected to the adjacent connecting boxes 61. A support block 712 is fixedly installed on the front side of the front connecting frame 711, and a drive motor 713 is fixedly installed on the top of the support block 712. A reciprocating screw 714 is fixedly installed on the end of the power output shaft of the drive motor 713. The rear end of the reciprocating screw 714 moves through the adjacent connecting frame 711 and is rotatably connected to the adjacent connecting frame 711. A screw nut 715 is movably sleeved on the outer periphery of the connecting frame 711 near the front end, and the top of the screw nut 715 is fixedly connected to the L-shaped frame 71.

[0050] Specifically, by setting the reciprocating lead screw 714 and lead screw nut 715, the L-shaped frame 71 can move back and forth, and the connecting rope 65 can be evenly wound around the outer circumference of the rotating roller 63.

[0051] A limiting block 7151 is fixedly installed at the bottom of the lead screw nut 715, and the front side of the limiting block 7151 moves through the limiting rod 7152, and the two ends of the limiting rod 7152 are fixedly connected to the adjacent connecting frame 711 respectively.

[0052] Specifically, by setting the limit rod 7152 and the limit block 7151, the movement of the lead screw nut 715 can be limited, thereby improving the stability of its movement.

[0053] In summary, the working principle of this invention is as follows: When it is necessary to install the utility pole 3, the utility pole 3 can be lifted by external tools and placed at a suitable position on top of the fixed base 2. Then, the hydraulic rod 81 can be activated by an external controller. The hydraulic rod 81 causes the movable block 82 to move downward, thereby enabling the two hinge rods 83 hinged to the bottom of the movable block 82 to push the adjacent L-shaped rack plates 84 to move to opposite sides, thereby enabling the adjacent rotating gears 85 to rotate in opposite directions. The drive handle 86 fixed on the rotating gears 85 enables the two fixed frames 87 to move to opposite sides under the limitation of the two adjacent limiting telescopic rods 871. The L-shaped block 88 fixed on the fixed frame 87 enables the two arc-shaped clamping plates 89 to move to opposite sides, thereby fixing the utility pole 3. After the utility pole 3 is installed, the connecting plate 5 fixed on the adjacent connecting box 61 is placed with two fixed Between ring 4, the two connecting plates 5 can be fixed with bolts. After they are fixed and stable, the T-shaped rod 641 can be pulled forward to move it away from the inner cavity of the adjacent limiting hole 643. Then, the drive disk 64 can be rotated to rotate the adjacent round rod 62, which in turn causes the rotating roller 63 fixed on the outer circumference of the round rod 62 to rotate and wind up the connecting rope 65, making the connecting rope 65 taut. After releasing the T-shaped rod 641, under the elastic force of the return spring 642, the T-shaped rod 641 can be inserted into the inner cavity of the return spring 642, which can generate a lateral pulling force on the utility pole 3 and improve its installation stability. When the connecting rope 65 breaks, the upper part of the broken rope can be wound up on the outer circumference of the adjacent rotating roller 63 with the cooperation of the torsion spring 621. With the cooperation of the protective component 7, the lower part of the connecting rope 65 can be limited to prevent the connecting rope 65 from swinging due to breakage and causing injury to others.

[0054] Example 2: This example is applied to the construction of a 220kV suburban transmission line. This area experiences seasonal strong winds (maximum wind speed 15m / s) and agricultural machinery operations (such as tractors and rotary tillers), which can easily cause external damage such as tilting or collisions to the transmission line poles. This device is required for protection. The implementation process is detailed below with reference to the device structure and actual construction procedures.

[0055] I. Equipment Pre-assembly and Foundation Construction

[0056] Mounting base fixing: First, excavate a foundation pit with a depth of 1.2m and a diameter of 1.5m at the construction point. Place the mounting base 1 horizontally into the foundation pit and fix it with C30 concrete. The concrete covers the bottom and side walls of the mounting base 1 by 30cm. Cure for 72 hours until the strength meets the standard to ensure that the mounting base 1 is rigidly connected to the ground and avoid displacement in the later stage.

[0057] Assembly of the fixed seat and the buffer assembly: Two dampers 11 are symmetrically installed at the bottom of the inner cavity of the mounting seat 1. Each damper 11 is fitted with a damping spring 12 on its outer periphery. The two ends of the damping spring 12 are welded and fixed to the bottom of the inner cavity of the mounting seat 1 and the bottom of the fixed seat 2, respectively. The fixed seat 2 is placed horizontally in the inner cavity of the mounting seat 1, so that the bottom of the fixed seat 2 is in contact with the top of the damper 11. At this time, the damper 11 and the damping spring 12 form a buffer structure, which can absorb ground vibration (such as vibration from agricultural machinery passing by) and slight collision impact.

[0058] Preliminary positioning of the utility pole: Hoist the 300mm diameter concrete utility pole 3 to the top center of the fixing base 2, and adjust the verticality of the utility pole 3 (calibrated with a level, the verticality deviation ≤0.3%); install two semi-circular fixing rings 4 on the outer periphery of the utility pole 3 near the top (2.5m from the top of the pole), and fasten them with M16 bolts through the connecting plate 5, so that the fixing rings 4 fit tightly with the outer periphery of the utility pole 3, providing an installation base for the anti-tilt component 6.

[0059] II. Activation of the fixing components: Achieving rigid fixation of the bottom of the utility pole.

[0060] This step securely connects the utility pole 3 to the mounting base 2 using the fixing component 8 to prevent the bottom of the utility pole 3 from becoming loose. The specific operation is as follows:

[0061] Power drive and transmission linkage: Start the hydraulic rod 81 at the top center of the inner cavity of the fixed seat 2, set the output pressure of the hydraulic rod 81 to 0.8MPa, the piston rod of the hydraulic rod 81 extends downward, pushing the movable block 82 fixed at its bottom end to descend vertically (descending stroke 15cm); when the movable block 82 descends, the two hinge rods 83 hinged on both sides of its bottom simultaneously open outward, and the end of the hinge rod 83 away from the movable block 82 pushes the L-shaped rack plate 84 to slide along the slide groove at the bottom of the inner cavity of the fixed seat 2 (the two L-shaped rack plates 84 move in opposite directions, moving a distance of 20cm).

[0062] Gear transmission and clamping: The teeth at the top of the L-shaped rack plate 84 mesh with the rotating gear 85. When the L-shaped rack plate 84 slides, it drives the rotating gear 85 to rotate around the fixed shaft 851 (the rear end of the fixed shaft 851 is welded to the rear side of the inner cavity of the fixed seat 2 to ensure stable rotation of the rotating gear 85); the drive handle 86 fixed at the top front side of the rotating gear 85 rotates synchronously with the gear. The front end of the drive handle 86 is inserted into the inner cavity of the fixed frame 87. During the rotation, it pushes the fixed frame 87 to move closer to the utility pole 3 (the fixed frame...). The limiting telescopic rods 871 on both sides of 87 extend and retract synchronously, restricting the fixed frame 87 to move only in the horizontal direction to avoid displacement); the L-shaped block 88 welded to the top of the fixed frame 87 moves with the fixed frame 87, and after its top end passes through the through hole at the top of the fixed seat 2, it drives the arc-shaped clamp 89 to fit against the outer periphery of the utility pole 3 until the rubber pads (5mm thick) on the inner side of the two arc-shaped clamps 89 are in close contact with the outer periphery of the utility pole 3. At this time, the hydraulic rod 81 stops working, and the bottom of the utility pole 3 is completely fixed with no lateral loosening space.

[0063] III. Anti-tilt component adjustment: Enhancing the lateral wind resistance of utility poles.

[0064] To address the issue of strong winds in suburban areas causing the top of utility pole 3 to tilt, lateral tensile support is constructed using anti-tilt components 6. The operating steps are as follows:

[0065] Connecting rope tension adjustment: The operator stands on top of the fixed base 2 and pulls the T-shaped rod 641 on the front side of the bottom connecting box 61 by hand. The T-shaped rod 641 moves forward along the through hole of the drive disc 64, and the return spring 642 sleeved on its outer circumference is compressed (compression amount 2cm). At this time, the rear end of the T-shaped rod 641 disengages from the limiting hole 643 on the front side of the connecting box 61, and the drive disc 64 rotates clockwise (speed 5r / min). The drive disc 64 is welded and fixed to the bottom round rod 62, driving the bottom round rod 62 to rotate synchronously. The rotating roller 63 fixed on the outer circumference of the bottom round rod 62 rotates with the round rod 62 and begins to wind up the connecting rope 65 (the connecting rope 65 is made of galvanized steel wire rope with a diameter of 8mm and a tensile strength ≥15kN) wrapped around its outer circumference.

[0066] Tension locking and reset spring reset: The end of the connecting rope 65 away from the bottom rotating roller 63 passes through the through holes of the upper and lower connecting boxes 61 and is fixedly connected to the top rotating roller 63. When the bottom rotating roller 63 is wound up, the connecting rope 65 pulls the top rotating roller 63 to rotate. The top round rod 62 rotates with the rotating roller 63 and twists the torsion spring 621 sleeved on its outer circumference (the two ends of the torsion spring 621 are respectively welded to the front side of the inner cavity of the top connecting box 61 and the outer circumference of the top round rod 62); when the tension of the connecting rope 65 reaches 3... When the torque reaches kN (measured with the aid of a tension gauge), stop rotating the drive disc 64, slowly release the T-shaped rod 641, and the return spring 642 elastically rebounds, pushing the T-shaped rod 641 to move backward. Its rear end is inserted into the corresponding limiting hole 643 on the front side of the connecting box 61 (the limiting holes 643 are evenly distributed along the circumference of the drive disc 64 with a spacing of 15°), thus fixing the drive disc 64. At this time, the connecting rope 65 forms an oblique tension on the utility pole 3, which can counteract the lateral thrust caused by strong winds and prevent the utility pole 3 from tilting.

[0067] IV. Activation of protective components: to prevent breakage of connecting ropes and external impacts.

[0068] To prevent injury from collisions with agricultural machinery or from accidental breakage of the connecting rope 65 followed by swinging, activate the protective assembly 7. The specific operation is as follows:

[0069] Adjusting the position of the protective structure: Start the drive motor 713 (model Y100L-2, power 3kW) on the top of the front connecting frame 711. The power output shaft of the drive motor 713 drives the reciprocating screw 714 to rotate clockwise (speed 10r / min). The screw nut 715 sleeved on the outer periphery of the reciprocating screw 714 is threadedly engaged with the reciprocating screw 714. The limiting block 7151 welded to the bottom of the screw nut 715 slides along the limiting rod 7152 (the two ends of the limiting rod 7152 are welded to the front and rear connecting frames 711, restricting the screw nut 715 to move only in the horizontal direction). This drives the L-shaped frame 71 welded to the top of the screw nut 715 to move towards the connecting rope 65 until the distance between the extrusion plate 75 on the inner side of the L-shaped frame 71 and the outer periphery of the connecting rope 65 is 5cm.

[0070] Buffering and Collision Absorption: Two fixed plates 72 are symmetrically welded to the front and back of the other side of the L-shaped frame 71. Two connecting telescopic rods 73 (travel 10cm) are welded to the front of the rear fixed plate 72. The front end of the connecting telescopic rod 73 is welded to the extrusion plate 75. The two ends of the connecting spring 74 sleeved on the outer periphery are welded to the rear fixed plate 72 and the extrusion plate 75 respectively. When agricultural machinery accidentally collides with the extrusion plate 75, the connecting telescopic rod 73 retracts and the connecting spring 74 compresses to absorb the impact force and prevent the connecting rope 65 from breaking directly due to force. At the same time, rubber blocks 76 (Shore hardness 50HA) are glued to the opposite side of the fixed plate 72 and the extrusion plate 75 to further buffer the collision and increase the friction with the connecting rope 65, preventing the connecting rope 65 from slipping.

[0071] V. Handling Abnormal Situations: Emergency Protection After Connecting Rope Breakage

[0072] If the connecting rope 65 breaks due to extreme weather (such as strong winds mixed with foreign objects), the device can automatically trigger the protection mechanism:

[0073] Rewinding of the broken end: After the connecting rope 65 breaks, the torsion spring 621 on the outer periphery of the top round rod 62 is released elastically, causing the top round rod 62 to rotate in the opposite direction. The top rotating roller 63 rotates with the round rod 62, quickly rewinding the upper half of the broken connecting rope 65 (rewinding time ≤ 2s), preventing the upper half of the connecting rope 65 from swinging in the wind, getting tangled in the utility pole 3, or falling to the ground.

[0074] Lower half limit: The lower half of the connecting rope 65 is still between the compression plate 75 and the fixing plate 72. Under the elastic force of the connecting spring 74, the compression plate 75 always fits the lower half of the connecting rope 65, limiting its lateral swing amplitude (swing range ≤10cm), preventing the broken lower half of the connecting rope 65 from hitting surrounding personnel or equipment, and reducing the risk of secondary injury.
