Description

Technical Field

[0001] This invention relates to the field of high-altitude operations technology, and more specifically, to a fall arrest rope safety lock and a fall arrest rope installation device. Background Technology

[0002] Currently, overhead transmission lines serve as the main arteries for power transmission. To ensure extremely high operational reliability, tower climbing operations are necessary to eliminate faults in these lines. However, tower climbing operations face several challenges, including insufficient coverage of existing fall arrestor rails, inconsistent supplier quality, and the time-consuming and laborious process of alternating safety belts. These issues severely impact the safety of personnel climbing the towers. Existing technologies for tower fall arrestor systems during overhead transmission line inspection or maintenance include foot spikes, safety belts, and fall arrestor hooks. During these systems, personnel climb the towers step by step, alternating between fall arrestor safety belts.

[0003] The inventors discovered through research that existing fall protection devices for working at heights have at least the following drawbacks:

[0004] Workers are required to perform high-altitude operations. To reach the work position, they need to carry safety ropes and use fall arrest hooks to climb step by step. This process is labor-intensive, time-consuming, and slow, consuming a lot of the workers' physical strength and seriously affecting work safety and efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a safety lock for a fall arrest rope and a fall arrest rope installation device, which can be used in conjunction with a drone to deploy fall arrest ropes, simplifying the deployment operation, reducing the labor intensity of workers, and improving operational safety and work efficiency.

[0006] The embodiments of the present invention are implemented as follows:

[0007] In a first aspect, the present invention provides a fall arrest rope safety lock, comprising:

[0008] A lock body having a first side and a second side opposite to each other in a preset direction, the first side being provided with a lock groove;

[0009] A lifting rod, wherein the lifting rod is slidably connected to the lock body in the preset direction;

[0010] The lock tongue is movably connected to the lock body, and the lifting rod is drivenly connected to the lock tongue. When the lifting rod slides relative to the lock body, the lifting rod drives the lock tongue to switch between a first position and a second position. In the first position, the lock tongue closes the opening of the lock groove, and in the second position, the lock tongue opens the opening of the lock groove.

[0011] In an optional embodiment, the fall arrestor safety buckle further includes a locking member, which is movably connected to the lock body so that the locking member has a lock position and an unlock position that can be switched between each other; when in the lock position, the locking member can restrict the bolt from moving from the first position to the second position; when in the unlock position, the bolt can move from the first position to the second position.

[0012] In an optional embodiment, the locking member is mounted on the lifting rod, and the lifting rod can, after driving the locking member to switch from the locked position to the unlocked position, drive the bolt to switch from the first position to the second position.

[0013] In an optional embodiment, the latch is rotatably connected to the lock body, and the lifting rod is rotatably connected to the latch. The lifting rod is used to drive the latch to rotate when sliding relative to the lock body in the preset direction, so that the latch switches between the first position and the second position.

[0014] In an optional embodiment, the latch includes a connected locking rod and a connector, the locking rod being rotatably connected to the lock body, the locking rod being used to close or open the slot of the lock groove, and the connector being used to connect to a fall arrest rope; the lifting rod is rotatably connected to the locking rod.

[0015] In an optional embodiment, the lifting rod includes a guide rod and a transmission rod. The guide rod is slidably connected to the lock body in the preset direction, and the locking member is fixedly connected to the guide rod. One end of the transmission rod is rotatably connected to the guide rod, and the other end of the transmission rod is rotatably connected to the connecting member. When the guide rod slides relative to the lock body in the preset direction, the transmission rod can drive the lock rod to rotate through the connecting member, so that the lock rod closes or opens the slot of the lock groove.

[0016] In an optional embodiment, the latch is provided with a limiting groove, the limiting groove having a limiting groove wall; when in the locked position, the locking member is inserted into the limiting groove, and the locking member and the limiting groove wall have a clearance space in the rotation direction of the latch, the locking member is used to abut against the limiting groove wall to restrict the latch from switching from the first position to the second position; when in the unlocked position, the locking member leaves the limiting groove;

[0017] During the process of the lifting rod driving the locking member to switch from the locked position to the unlocked position, the limiting groove wall can rotate in the direction close to the locking member.

[0018] In an optional embodiment, the locking tongue is provided with a fixed pulley for winding a fall arrest rope.

[0019] Secondly, the present invention provides a fall arrest rope installation device, the fall arrest rope installation device comprising:

[0020] The drone hoisting mechanism and the fall arrest rope safety buckle as described in any of the foregoing embodiments are provided, wherein the drone hoisting mechanism is used to connect to the drone, and the drone hoisting mechanism and the fall arrest rope safety buckle are detachably connected.

[0021] In an optional embodiment, the fall arrestor rope installation device further includes a hanging rod, a hook, and a hanging ring. The hanging rod is used to connect to the drone, and the hook is connected to the hanging rod. The hanging ring is connected to the lifting rod, and the hook and the hanging ring are detachably connected.

[0022] The beneficial effects of the embodiments of the present invention are:

[0023] The fall arrestor safety lock provided in this embodiment can be used with drones and other accessories to safely deliver the fall arrestor rope to the designated location for high-altitude operations, thereby providing safety for personnel working at heights. During the deployment of the fall arrestor rope, the drone connects to the lifting rod of the safety lock via an accessory, lifting the entire lock. After lifting, the first side of the lock body is below the second side; that is, the first side can be understood as the bottom side of the lock body, and the second side as the top side, with the lock groove opening facing downwards. Furthermore, under the weight of the lock body itself, the lifting rod moves relative to the lock body, causing the latch to move to the second position, meaning the latch remains in the unlocked lock groove opening. When the drone reaches the set height, the lock groove opening is above the crossbeam to be suspended, essentially aligned with it. The drone continues to descend and gradually approach the crossbeam, using the lock body's groove to guide the crossbeam into the lock groove. As the drone continues its descent, the lock body contacts the crossbeam. The crossbeam supports the weight of the lock body, preventing it from descending with the drone. However, the lifting rod descends with the drone, sliding relative to the lock body and causing the bolt to move relative to the lock body. This switches the bolt from its second position to its first position, closing the lock groove. At this point, the crossbeam is positioned within the closed loop structure formed by the lock body and bolt, securing the safety latch in its suspended position. Before being hoisted to the crossbeam, the safety latch can be raised along with the fall arrest rope, thus securing the rope. The fall arrest rope installation is achieved via drone, eliminating the need for workers to climb levels, reducing labor intensity, saving time and effort, increasing work efficiency, and improving worker safety. Simultaneously, the safety latch's downward movement engages the crossbeam in the lock groove, reducing operational difficulty and improving efficiency. Attached Figure Description

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Currently, in the field of high-altitude operations, it is necessary to secure fall arrest ropes to designated locations at heights to provide safety for workers. Existing technologies primarily employ two methods for securing fall arrest ropes: one involves workers climbing the tower step by step, carrying the fall arrest rope to the designated height, and then securing it. This method is labor-intensive, time-consuming, inefficient, and unsafe. The other method uses a drone to hoist the fall arrest rope to the designated location and secures it to the tower using a safety lock. This method reduces the labor intensity for workers; however, existing safety locks use electronic locking rods (310), which are susceptible to failure and offer low safety.

[0041] In view of this, the designers have provided a fall arrest rope safety lock 001, which can use a drone to move the fall arrest rope to the target crossarm and fix it, reducing the labor intensity of the workers and improving the safety of the operation; at the same time, it relies on the mechanical structure to achieve automatic locking and unlocking, with a low failure rate and high reliability.

[0042] Please combine Figures 1-6 In this embodiment, the fall arrestor safety buckle 001 includes a lock body 100, a lifting rod 200, and a locking tongue 300. The lock body 100 has a first side 101 and a second side 102 opposite to each other in a preset direction, and the first side 101 is provided with a lock groove 103. The lifting rod 200 is slidably connected to the lock body 100 in the preset direction. The locking tongue 300 is movably connected to the lock body 100, and the lifting rod 200 is drively connected to the locking tongue 300; when the lifting rod 200 slides relative to the lock body 100, the lifting rod 200 drives the locking tongue 300 to switch between a first position and a second position; wherein, when in the first position, the locking tongue 300 closes the groove 104 of the lock groove 103, and when in the second position, the locking tongue 300 opens the groove 104 of the lock groove 103.

[0043] Based on the above, the working principle of the fall arrest rope safety buckle 001 provided in this embodiment is as follows:

[0044] Please combine Figure 3 , Figure 4 and Figure 7The fall arrestor safety lock 001 is used in conjunction with a drone to suspend the fall arrestor rope on the latch 300, and the lifting rod 200 is connected to the drone. The drone is operated to carry the entire fall arrestor safety lock and the fall arrestor rope installed on the latch 300 together. After being lifted, the first side 101 of the lock body 100 is below the second side 102; that is, the first side 101 can be understood as the bottom side of the lock body 100, and the second side 102 can be understood as the top side of the lock body 100. Thus, the groove 104 of the lock groove 103 faces downwards. Furthermore, under the weight of the lock body 100 itself, the lifting rod 200 moves relative to the lock body 100, causing the latch 300 to move to the second position, meaning the latch 300 is always in the position where the groove 104 of the lock groove 103 is not locked. When the drone reaches the set altitude, the slot 104 of the locking groove 103 is positioned above the crossarm to be suspended, with the slot 104 essentially aligned with it. The drone continues to descend, gradually approaching the target crossarm, and the target crossarm is guided into the locking groove 103 through the slot 104 on the locking body 100. As the drone continues its descent, the locking body 100 first contacts the target crossarm, its weight supported by the target crossarm. At this point, the locking body 100 will not descend with the drone. The lifting rod 200 can descend with the drone. During the descent, the lifting rod 200 slides relative to the lock body 100 and drives the locking tongue 300 to move relative to the lock body 100, so that the locking tongue 300 switches from the second position to the first position, that is, the locking tongue 300 closes the slot 104 of the lock groove 103. At this time, the target crossarm is located in the closed loop structure formed by the lock body 100 and the locking tongue 300, completing the fixation of the suspension position of the safety lock, that is, realizing the installation and fixation of the fall arrest rope.

[0045] This design allows for the installation of the fall arrestor rope using a drone, eliminating the need for workers to climb up and down stairs. This reduces the workload for workers, saves time and effort, and improves work efficiency and safety. Simultaneously, the safety latch moves from top to bottom, engaging the crossbeam into the locking groove 103, reducing operational difficulty and increasing efficiency. The opening and closing of the slot 104 in the locking groove 103 is an automated mechanical operation, ensuring convenient operation and high reliability.

[0046] The following embodiments illustrate the detailed structure of the fall arrest rope safety buckle 001 provided in this application.

[0047] Please combine Figure 5In this embodiment, optionally, the lock body 100 includes a first rod 110, a second rod 120, a third rod 130, and a first pivot 140 connected in sequence. One end of the first rod 110 is connected to the second rod 120, and the other end of the first rod 110 is suspended. One end of the third rod 130 is connected to the second rod 120, and the other end of the third rod 130 is swivel-shaped. The first rod 110 and the third rod 130 are located at opposite ends of the second rod 120 and are arranged relatively parallel to each other. In this way, the first rod 110, the second rod 120, and the third rod 130 cooperate to define a "U"-shaped structure with an opening on one side, that is, the first rod 110, the second rod 120, and the third rod 130 cooperate to define a lock groove 103, and the groove 104 of the lock groove 103 is the opening of the "U"-shaped structure. Meanwhile, the first rod 110 is provided with an assembly groove 111, which has two opposing sidewalls. Each sidewall has a strip-shaped guide hole 112, the length of which extends in a predetermined direction. Both the first rod 110 and the third rod 130 extend in the predetermined direction. The second rod 120 is provided with an assembly hole 121, which penetrates the bottom wall of the assembly groove 111 and communicates with it. The third rod 130 is provided with a limit hole 131. A first rotating shaft 140 is connected to the first rod 110 and is located within the assembly groove 111, penetrating both sidewalls. The latch 300 is rotatably engaged with the lock body 100 via the first rotating shaft 140.

[0048] Please combine Figure 2 and Figure 3In this embodiment, optionally, the lifting rod 200 includes a guide rod body 210 and a transmission rod body 220. The guide rod body 210 passes through the mounting hole 121, and two coaxially arranged guide shafts 230 are provided on the guide rod body 210. The two guide shafts 230 are slidably passed through two guide holes 112, so that the guide rod body 210 and the first rod 110 are slidably connected in a preset direction. The guide shafts 230 slide in the guide holes 112, and the two hole walls of the guide holes 112 in the preset direction limit the sliding range of the guide shafts 230, thereby limiting the sliding range of the lifting rod 200 relative to the lock body 100 and preventing the lifting rod 200 from disengaging from the lock body 100. Meanwhile, the transmission rod 220 is configured as an arc-shaped rod. One end of the transmission rod 220 is rotatably connected to the guide rod 210 via a second rotating shaft 240, and the other end of the transmission rod 220 is provided with an oblong hole 221 extending in the extension direction of the transmission rod 220. A third rotating shaft 250 passes through the oblong hole 221 and is fixed to the latch 300. The transmission rod 220 and the latch 300 are rotatably connected via the third rotating shaft 250. When the guide rod 210 slides relative to the lock body 100 in a preset direction, the transmission rod 220 can drive the latch 300 to rotate relative to the lock body 100 around the axis of the first rotating shaft 140, so that the latch 300 closes or opens the slot 104 of the lock groove 103. It should be understood that the first rotating shaft 140, the second rotating shaft 240, and the third rotating shaft 250 are all arranged in parallel.

[0049] Please combine Figure 2 and Figure 6In this embodiment, optionally, the locking tongue 300 includes a locking rod 310, a connecting member 320, and a fixed pulley 330. The locking rod 310 and the connecting member 320 are connected, and the fixed pulley 330 is rotatably mounted on the connecting member 320. The connecting member 320 can be a rod-shaped structure, and the connecting member 320 and the locking rod 310 have a non-zero included angle. The locking rod 310 passes through the assembly groove 111, and the locking rod 310 is rotatably connected to the first rod 110 of the lock body 100 through a first rotating shaft 140. The locking rod 310 is used to close or open the slot 104 of the lock groove 103, and when the locking rod 310 closes the slot 104 of the lock groove 103, the end of the locking rod 310 away from the connecting member 320 is engaged in the limiting hole 131. The fixed pulley 330 on the connecting member 320 is used for winding the fall arrest rope, thereby positioning the fall arrest rope. One end of the force transmission rod is rotatably connected to the locking rod 310 via a third rotating shaft 250. The third rotating shaft 250 is located on the side of the first rotating shaft 140 away from the third rod 130. In other words, the locking rod 310 has a first end and a second end. The third rotating shaft 250 is mounted on the first end, and the second end is used to engage with the limiting hole 131 on the third rod 130. The first end and the second end are located on both sides of the first rotating shaft 140 in the length direction of the locking rod 310. When the force transmission rod pulls the first end of the locking rod 310 upward through the third rotating shaft 250, the second end of the locking rod 310 rotates downward accordingly. Similarly, when the force transmission rod pulls the first end of the locking rod 310 downward through the third rotating shaft 250, the second end of the locking rod 310 rotates upward accordingly.

[0050] Furthermore, a limiting groove 311 is provided on the locking rod 310, and the limiting groove 311 has a limiting groove wall 312, which is the bottom wall of the limiting groove 311. The groove opening 104 of the limiting groove 311 is located at the first end, the limiting groove wall 312 is spaced from the second end, and the limiting groove wall 312 is located on the side of the first rotating shaft 140 closer to the second end, with a gap between the limiting groove wall 312 and the first rotating shaft 140.

[0051] Please combine Figure 2 , Figure 3 and Figure 4In this embodiment, optionally, the fall arrestor safety buckle 001 also includes a locking member 400. The locking member 400 is fixed to the guide rod 210, and the locking member 400 can slide back and forth relative to the lock body 100 in a preset direction with the guide rod 210. Furthermore, when the locking member 400 slides relative to the lock body 100, the locking member 400 has a lock position and an unlock position that can be switched between each other; when in the lock position, the locking member 400 can restrict the bolt 300 from moving from the first position to the second position; when in the unlock position, the bolt 300 can move from the first position to the second position. Simultaneously, the positions of the locking member 400 and the locking tongue 300 are linked. That is, during the movement of the lifting rod 200, it can simultaneously drive the locking member 400 and the locking tongue 300. When the locking member 400 is in the locked position, the locking tongue 300 is in the first position; when the locking member 400 is in the unlocked position, the locking tongue 300 is in the second position. When the lifting rod 200 moves the locking member 400 from the locked position to the unlocked position, it can move the locking tongue 300 from the first position to the second position. In other words, when the locking member 400 is in the locked position, applying force to the locking tongue 300 prevents it from moving from the first position to the second position, thus maintaining the locking tongue 300 in the first position. When force is applied to the lifting rod 200, the lifting rod 200 can drive the locking member 400 to switch from the locked position to the unlocked position. At this time, the locking member 400 loses its limitation on the bolt 300. If force is continued to be applied to the lifting rod 200, the lifting rod 200 can drive the bolt 300 to switch from the first position to the second position.

[0052] Please combine 3 and Figure 4Specifically, when the locking member 400 is in the locked position, the locking member 400 is inserted into the limiting slot 311 on the locking rod 310, and the locking member 400 is located between the first rotating shaft and the limiting slot wall 312. There is also a gap between the locking member 400 and the limiting slot wall 312 to form a clearance space 313. Because of the clearance space 313, when force is applied to the lifting rod 200, causing it to move the locking member 400 and the bolt 300, the locking member 400 can first pull out the limiting slot 311 to switch to the unlocked position. In other words, in order for the locking member 400 to switch from the locked position to the unlocked position, force needs to be applied to the lifting rod 200. Applying force to the lifting rod 200 will inevitably cause the bolt 300 to move from the first position to the second position. Because of the clearance space 313, during the process of the locking member 400 pulling out the limiting slot 311, the bolt 300 can rotate at a certain angle. During the process of the locking member 400 pulling out the limiting slot 311, the limiting slot wall 312 will not prematurely abut against the locking member 400, and there will be no interference. The lifting rod 200, the locking member 400 and the bolt 300 can move smoothly. With this design, the movement of both the locking member 400 and the locking tongue 300 is achieved by the lifting rod 200. When the locking tongue 300 is in the position of closing the slot 104 of the lock groove 103, if the lifting rod 200 does not pull the locking member 400 and the locking tongue 300 to rise, the locking member 400 will not rise away from the limiting slot 311. At this time, even if the locking tongue 300 is rotated, the locking tongue 300 can only directly abut against the locking member 400 after rotating a small angle. The locking tongue 300 will not switch to the second position, that is, the locking tongue 300 will not automatically open the slot 104 of the lock groove 103, and the target crossbeam located in the lock groove 103 will not fall out, thus ensuring high safety.

[0053] In other words, during high-altitude operations, the lock body 100 is suspended on the target crossbeam, and the fall arrest rope is wound around the fixed pulley 330. When the fall arrest rope is subjected to external force, it will transmit the external force to the lock tongue 300 and drive the lock body 100 to move relative to the target crossbeam. When the force transmitted by the fall arrest rope to the lock tongue 300 has an angle with the preset direction, the fall arrest rope may apply a torque to the lock tongue 300, causing the lock tongue 300 to have a rotational tendency to switch from the first position to the second position. It is precisely because of the design of the locking member 400 that the movement of the lock tongue 300 is hindered, preventing the lock tongue 300 from opening the slot 104 of the lock groove 103 under the pull of the fall arrest rope, thereby improving the safety during the operation.

[0054] The fall arrestor safety lock 001 provided in this embodiment achieves the linkage movement of the locking tongue 300 and the locking member 400 through a mechanical structure. When the locking tongue 300 is in the closed position of the groove 104 of the lock groove 103, the locking member 400 is in the locked position, effectively preventing the locking tongue 300 from automatically opening under the action of the fall arrestor rope, thus improving safety during operation. Simultaneously, after the operation is completed, force can be applied to the lifting rod 200, simultaneously moving the locking tongue 300 and the locking member 400. After the locking member 400 switches from the locked position to the unlocked position, the locking tongue 300 can switch from the first position to the second position, thereby opening the groove 104 of the lock groove 103, facilitating the removal of the lock body 100 from the target crossarm. The entire process is highly automated, with convenient mounting and dismounting, resulting in high operational efficiency.

[0055] Please combine Figure 7 This embodiment also provides a fall arrest rope installation device, including a drone hoisting mechanism 002 and a fall arrest rope safety lock 001 as described in the above embodiment. The drone hoisting mechanism 002 is used to connect with the drone, and the drone hoisting mechanism 002 and the fall arrest rope safety lock 001 are detachably connected.

[0056] Optionally, the fall arrestor installation device also includes a hanging rod 021, a hook 022, and a hanging ring 023. The hanging rod 021 is used to connect to the drone, and the hook 022 is connected to the hanging rod 021. The hanging ring 023 is rotatably connected to the guide rod 210 of the lifting rod 200, and the hook 022 is detachably connected to the hanging ring 023. That is, when it is necessary to use a drone to position the fall arrestor rope to the target crossarm, the hanging rod 021 is installed on the drone, the hook 022 is hooked to the hanging ring 023, the drone takes off, and through the cooperation of the hook 022 and the hanging ring 023, the fall arrestor rope safety lock 001 and the fall arrestor rope move together. Once the drone reaches the designated position, it descends and connects the lock body 100 to the target crossarm. The drone continues its descent, but the lifting rod 200 cannot descend, and the hanging ring 023 mounted on the lifting rod 200 cannot descend. The hook 022 descends relative to the hanging ring 023. After descending a certain height, the hook 022 detaches from the hanging ring 023. The drone then flies laterally, separating the hook 022 from the hanging ring 023, allowing the drone to return normally. When it is necessary to disassemble the safety lock, the drone carries the hook 022 and flies above the hanging ring 023, connecting the hook 022 to the hanging ring 023. The drone ascends, the locking tongue 300 opens, and the lock body 100 detaches from the target crossarm. The drone then returns together with the fall arrest rope safety lock 001, the fall arrest rope, and the drone hoisting mechanism 002.
