Description

Technical Field

[0001] This invention relates to the field of safety protection technology for high-altitude operations, and in particular to high-altitude operation locks and methods for using high-altitude operation locks. Background Technology

[0002] To ensure the safety of workers, safety ropes must be secured to overhead ropes when performing high-altitude operations to prevent falls. Especially when workers are moving on the overhead ropes, one end of the safety rope must be secured to the worker, and the other end must be secured to the overhead rope using a locking buckle. As the worker moves, the buckle moves synchronously along the direction of the overhead rope, thus providing safety protection. Therefore, the locking buckle is crucial for ensuring the safety of workers performing high-altitude operations.

[0003] Taking the maintenance of power lines between towers as an example, due to the different vertical heights of the towers, the cable lines between the towers will tilt to one side. Although the existing locks and overhead ropes can ensure that power grid workers will not fall, if a worker slips while moving along the power line from the higher end to the lower end, even if a fall does not occur, the locks will slide quickly on the overhead ropes, causing the maintenance worker to move quickly along the overhead ropes, creating a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a high-altitude work safety lock and a method for using the high-altitude work safety lock, in order to solve the problem that the existing high-altitude work safety lock can only ensure that the power grid workers will not fall. If the workers are moving along the power line from one end to the other and accidentally slip and fall, even if they do not fall, the lock will slide quickly on the overhead rope, causing the maintenance workers to move quickly along the overhead rope, creating a safety hazard.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A high-altitude work lock includes a lock body and a deceleration mechanism. The deceleration mechanism includes a first torsion spring, a first deceleration assembly, and two rolling support assemblies. The two rolling support assemblies are symmetrically distributed on both sides of the first deceleration assembly.

[0007] The first deceleration assembly includes a deceleration rod and a deceleration component. One end of the deceleration rod is fixedly connected to the deceleration component, and the other end is rotatably connected to the locking body. The first torsion spring is sleeved at the fixed connection between the deceleration rod and the deceleration component. One end of each of the two rolling support assemblies is rotatably connected to the fixed connection between the deceleration rod and the deceleration component and is respectively connected to the two ends of the first torsion spring.

[0008] The overhead rope can be threaded through the locking body and the two rolling support components, and rolls in cooperation with the two rolling support components.

[0009] The speed reducer has a first working position suspended above the overhead rope and the two rolling support assemblies, and a second working position pressed against the overhead rope. The first torsion spring can drive the speed reducer to switch from the second working position to the first working position.

[0010] As a preferred embodiment of the above-mentioned high-altitude operation lock, the rolling support assembly includes a first connecting rod and a rolling support wheel set. The first end of the first connecting rod is rotatably connected to the fixed connection between the deceleration rod and the deceleration component. The first ends of the first connecting rods of the two rolling support assemblies are fixedly connected to the two ends of the first torsion spring one to one. The second end of the first connecting rod is provided with the rolling support wheel set. The overhead rope can be threaded through the rolling support wheel set and roll in cooperation with the rolling support wheel set.

[0011] When the speed reducer is in the first working position, it is suspended above the overhead rope and the two rolling support wheel sets.

[0012] As a preferred embodiment of the above-mentioned high-altitude operation lock, the rolling support wheel assembly includes a second connecting rod rotatably connected to the second end of the first connecting rod, and two rolling support wheels. The two rolling support wheels are respectively rotatably connected to the two ends of the second connecting rod. The overhead rope can pass through the gap between the two rolling support wheels and roll in cooperation with the two rolling support wheels.

[0013] As a preferred embodiment of the above-mentioned high-altitude operation lock, the rolling support assembly further includes a second torsion spring, which is disposed at the rotatable connection between the first link and the second link, and the two ends of the second torsion spring are respectively connected to the first link and the second link.

[0014] As a preferred embodiment of the above-mentioned high-altitude operation lock, the first connecting rod and the second connecting rod are both distributed at one end of the rolling support wheel along the axial direction, the deceleration rod is distributed at the other end of the rolling support wheel along the axial direction, and the deceleration component is located between the first connecting rod and the deceleration rod.

[0015] As a preferred embodiment of the above-mentioned high-altitude operation lock, the outer circumferential surface of the rolling support wheel is provided with an annular limiting groove, which is used to accommodate the overhead rope.

[0016] As a preferred embodiment of the above-mentioned high-altitude work lock, the high-altitude work lock further includes two opposing blocking components. The blocking components include a stop bar rotatably connected to the inner peripheral wall of the lock body, and a third torsion spring disposed on the lock body. The two ends of the third torsion spring are respectively connected to the lock body and the stop bar.

[0017] The two stops are configured to open under external force to form a channel for the passage of the overhead rope, and the elastic restoring force of the third torsion spring can cause the two stops to close and block the overhead rope.

[0018] As a preferred embodiment of the above-mentioned high-altitude work lock, the high-altitude work lock further includes two opposing second deceleration components, which are located away from the deceleration mechanism relative to the blocking component;

[0019] The second deceleration assembly includes a fastening member rotatably connected to the inner peripheral wall of the latch body, and a fourth torsion spring disposed on the latch body, the two ends of the fourth torsion spring being connected to the latch body and the fastening member, respectively.

[0020] The two fasteners are configured to engage under external force to form a receiving cavity for accommodating the overhead rope, and the elastic restoring force of the fourth torsion spring can drive the two fasteners away from each other and make the openings of the fasteners face the stop bar.

[0021] As a preferred embodiment of the above-mentioned high-altitude operation lock, the inner peripheral wall of the lock body is further provided with a first resistance limiting groove, which is distributed between the two second deceleration components and is used to accommodate the overhead rope.

[0022] A method for using a high-altitude work safety lock, which is used in the aforementioned high-altitude work safety lock, includes the following:

[0023] Lock the buckle body to the overhead rope, so that the buckle body slides on the overhead rope;

[0024] The overhead rope is threaded through the two rolling support assemblies, so that the rolling support assemblies and the overhead rope roll together, and the deceleration component is suspended above the overhead rope and the two rolling support assemblies.

[0025] When the locking body is subjected to an external force and moves downward, the deceleration component moves downward synchronously and abuts against the overhead rope, and the two rolling support components move away from each other;

[0026] When the external force is removed, the elastic restoring force of the first torsion spring causes the decelerator to be suspended above the overhead rope and the two rolling support assemblies, and causes the two rolling support assemblies to move closer to each other.

[0027] The beneficial effects of this invention are:

[0028] The purpose of this invention is to provide a high-altitude work lock and a method for using the high-altitude work lock. The high-altitude work lock includes a lock body and a deceleration mechanism. The deceleration mechanism includes a first torsion spring, a first deceleration assembly, and two rolling support assemblies, which are symmetrically distributed on both sides of the first deceleration assembly. The first deceleration assembly includes a deceleration rod and a deceleration element. One end of the deceleration rod is fixedly connected to the deceleration element, and the other end is rotatably connected to the lock body. The first torsion spring is sleeved at the fixed connection between the deceleration rod and the deceleration element. One end of each of the two rolling support assemblies is rotatably connected to the fixed connection between the deceleration rod and the deceleration element and is respectively connected to both ends of the first torsion spring. Before performing high-altitude work, the lock body of the high-altitude work lock is locked to the overhead rope, so that the lock body slides on the overhead rope. The overhead rope is then passed through the two rolling support assemblies, so that the two rolling support assemblies roll in cooperation with the overhead rope. At this time, the deceleration element is suspended above the overhead rope and the two rolling support assemblies and is located in the first working position.

[0029] When workers are working normally at height, the worker slides the locking body onto the overhead rope, causing the two rolling support components to roll synchronously onto the overhead rope. During this process, the deceleration component moves synchronously along the extension direction of the overhead rope and is suspended above the overhead rope and the two rolling support components. When a downward force is applied to the locking body, or when the worker slips due to operational error during movement, especially when the worker slips due to operational error while moving from the higher end to the lower end of the overhead rope, the downward force or the worker's own weight causes the deceleration lever and deceleration component to move downward synchronously, causing the deceleration component to press against the overhead rope. At this time, the deceleration component and the overhead rope... The increased friction between the ropes effectively slows down the load. During this process, the first torsion spring undergoes elastic deformation, and the two rolling support components rotate around the fixed connection between the decelerator and the decelerator rod, moving away from each other. This increases the interaction force between the rolling support components and the overhead rope, thereby increasing the friction between them and allowing the rolling support components to also achieve a certain deceleration effect. This effectively reduces the safety hazards for workers performing high-altitude operations. When the workers resume normal high-altitude operations or cease applying downward force to the locking body, the elastic restoring force of the first torsion spring causes the two rolling support components to move closer together, causing the decelerator to suspend again.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0042] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0045] This invention provides a high-altitude work locking mechanism, such as... Figure 1-4 As shown, the high-altitude work lock includes a lock body 1 and a deceleration mechanism. The deceleration mechanism includes a first torsion spring, a first deceleration assembly 2, and two rolling support assemblies 3. The two rolling support assemblies 3 are symmetrically distributed on both sides of the first deceleration assembly 2. The first deceleration assembly 2 includes a deceleration rod 21 and a deceleration element 22. One end of the deceleration rod 21 is fixedly connected to the deceleration element 22, and the other end is rotatably connected to the lock body 1. The first torsion spring is sleeved at the fixed connection between the deceleration rod 21 and the deceleration element 22. One end of each of the two rolling support assemblies 3 is rotatably connected to the fixed connection between the deceleration rod 21 and the deceleration element 22 and is respectively connected to the two ends of the first torsion spring. The overhead rope 100 can pass through the lock body 1 and the two rolling support assemblies 3 and roll in cooperation with the two rolling support assemblies 3. The deceleration element 22 has a first working position that is suspended above the overhead rope 100 and the two rolling support assemblies 3, and a second working position that is pressed against the overhead rope 100. The first torsion spring can drive the deceleration element 22 to switch from the second working position to the first working position.

[0046] Specifically, before performing high-altitude operations, the locking body 1 of the high-altitude operation lock is locked to the overhead rope 100, so that the locking body 1 slides on the overhead rope 100. The overhead rope 100 is then threaded through two rolling support components 3, so that the two rolling support components 3 roll in cooperation with the overhead rope 100. At this time, the deceleration component 22 is suspended above the overhead rope 100 and the two rolling support components 3 and is located in the first working position.

[0047] When workers are working normally at height, the worker slides the locking body 1 onto the overhead rope 100, causing the two rolling support components 3 to roll synchronously onto the overhead rope 100. During this process, the deceleration component 22 moves synchronously along the extension direction of the overhead rope 100 and is suspended above the overhead rope 100 and the two rolling support components 3. When a downward force is applied to the locking body 1, or when the worker slips due to improper operation during movement, especially when the worker slips due to improper operation while moving from the higher end to the lower end of the overhead rope 100, the downward force or the worker's own weight causes the deceleration lever 21 and the deceleration component 22 to move downward synchronously, so that the deceleration component 22 presses against the overhead rope 100. At this time, the deceleration... The increased friction between component 22 and the overhead rope 100 effectively reduces speed. During this process, the first torsion spring undergoes elastic deformation, and the two rolling support components 3 rotate around the fixed connection between the decelerator component 22 and the decelerator rod 21 and move away from each other. This increases the interaction force between the rolling support components 3 and the overhead rope 100, thereby increasing the friction between them. This allows the rolling support components 3 to also achieve a certain deceleration effect, effectively reducing safety hazards for workers performing high-altitude operations. When the workers resume normal high-altitude operations or cease applying downward force to the locking body 1, the elastic restoring force of the first torsion spring causes the two rolling support components 3 to move closer together, causing the decelerator component 22 to suspend again.

[0048] Therefore, this high-altitude work lock will not affect the worker's movement along the extension direction of the overhead rope 100 during normal work. When a downward force is applied to the lock body 1, or when the worker slips due to carelessness during movement, especially when the worker slips due to carelessness while moving from the higher end to the lower end of the overhead rope 100, it can effectively slow down the worker, thereby effectively reducing the safety hazards when the worker is working at height.

[0049] Preferably, such as Figure 1-3 As shown, in this embodiment, the reducer 22 is a fixed wheel, which is fixedly connected to one end of the reducer 21. This design reduces the number of parts and facilitates processing and assembly. It is understood that the shape of the reducer 22 can also be adjusted adaptively according to actual working conditions.

[0050] More preferably, such as Figure 1-3As shown, the outer peripheral surface of the deceleration member 22 is provided with a second resistance limiting groove 221, and the overhead rope 100 can be accommodated in the second resistance limiting groove 221. This arrangement limits the placement position of the overhead rope 100, preventing the risk of the overhead rope 100 detaching from the deceleration member 22 due to external force when the deceleration member 22 is pressed against the overhead rope 100, thereby further improving the performance of the high-altitude work lock. Specifically, in this embodiment, the second resistance limiting groove 221 is annular.

[0051] More preferably, the sidewall of the second resistance limiting groove 221, at least the portion in contact with the overhead rope 100, is provided with an anti-slip pattern. This design further enhances the deceleration performance of the reducer 22.

[0052] Among them, such as Figure 1-3 As shown, the rolling support assembly 3 includes a first connecting rod 31 and a rolling support wheel set 32. The first end of the first connecting rod 31 is rotatably connected to the fixed connection between the deceleration rod 21 and the deceleration member 22. The first ends of the first connecting rods 31 of the two rolling support assemblies 3 are connected to the two ends of the first torsion spring one by one. The second end of the first connecting rod 31 is provided with a rolling support wheel set 32. The overhead rope 100 can pass through the rolling support wheel set 32 ​​and roll in cooperation with the rolling support wheel set 32. When the deceleration member 22 is in the first working position, the deceleration member 22 is suspended above the overhead rope 100 and the two rolling support wheel sets 32. Specifically, during the synchronous downward movement of the deceleration lever 21 and the deceleration component 22, the angle between the two first connecting rods 31 increases, causing the two rolling support wheel sets 32 to roll on the overhead rope 100 and separate from each other. When the operator resumes normal high-altitude work, or when no longer applying downward force to the locking body 1, the elastic restoring force of the first torsion spring causes the angle between the two first connecting rods 31 to decrease, causing the two rolling support wheel sets 32 to roll on the overhead rope 100 and move closer to each other. At this time, the deceleration component 22 is suspended above the overhead rope 100 and the two rolling support wheel sets 32.

[0053] Specifically, such as Figure 1-3As shown, the rolling support wheel assembly 32 includes a second connecting rod 321 rotatably connected to the second end of the first connecting rod 31, and two rolling support wheels 322. The two rolling support wheels 322 are respectively rotatably connected to the two ends of the second connecting rod 321. The overhead rope 100 can pass through the gap between the two rolling support wheels 322 and roll in cooperation with the two rolling support wheels 322. This arrangement enables the rolling support wheel assembly 32 to roll in cooperation with the overhead rope 100. Secondly, the rolling support wheels 322 at both ends of the second connecting rod 321 can improve the stability of the rolling support wheel assembly 32 and the overhead rope 100 rolling in cooperation. Furthermore, when the worker's own weight drives the deceleration rod 21 and the deceleration component 22 to move downwards synchronously, causing the deceleration component 22 to press against the overhead rope 100, the interaction force between the two rolling support wheels 322 and the overhead rope 100 increases, increasing the mutual friction between them, so that the rolling support wheel assembly 32 can also play a certain deceleration role.

[0054] More specifically, the rolling support assembly 3 also includes a second torsion spring, which is disposed at the rotatable connection between the first link 31 and the second link 321, and both ends of the second torsion spring are connected to the first link 31 and the second link 321 respectively. By rotatably connecting the first link 31 and the second link 321, and providing the second torsion spring at the rotatable connection, when the worker is working normally at height, the second torsion spring can limit the included angle between the first link 31 and the second link 321 to remain unchanged, so that both rolling support wheels 322 of the rolling support wheel assembly 32 are in rolling engagement with the overhead rope 100; when a downward force is applied or the worker's own weight is applied, the deceleration lever 21 and the deceleration component 22 move downward synchronously, so that the deceleration component 22 presses against the overhead rope 100, synchronously... The first and second torsion springs undergo elastic deformation, increasing the angle between the two first connecting rods 31 and causing the two rolling support wheel sets 32 to move further apart. This also increases the included angle between the first connecting rod 31 and the second connecting rod 321, ensuring that the two rolling support wheels 322 of the rolling support wheel set 32 ​​can still roll in cooperation with the overhead rope 100. This increases the interaction force between the two rolling support wheels 322 of the rolling support wheel set 32 ​​and the overhead rope 100, increasing the mutual friction between them. As a result, the rolling support wheel set 32 ​​can also achieve a certain deceleration effect.

[0055] Specifically, such as Figure 1 and Figure 3 As shown, in this embodiment, the rolling support assembly 3 is W-shaped. It can be understood that the number of second torsion springs and rolling support wheel sets 32 can be increased adaptively according to actual working conditions, and the second connecting rods 321 of multiple rolling support wheel sets 32 are connected end to end by the second torsion springs in a zigzag shape.

[0056] Understandably, by adjusting the relative lengths of the first link 31 and the second link 321, the included angle between the two first links 31, and the angle between the first link 31 and the second link 321, the reducer 22 can be suspended above the overhead rope 100 and the two rolling support wheel sets 32 when it is in the first working position.

[0057] Preferably, such as Figure 1-3 As shown, the outer circumferential surface of the rolling support wheel 322 is recessed with an annular limiting groove 3221, which is used to accommodate the overhead rope 100. This arrangement can further limit the position of the overhead rope 100 and prevent the overhead rope 100 from detaching from the rolling support wheel 322, thereby further improving the performance of the high-altitude operation lock.

[0058] More preferably, the sidewall of the annular limiting groove 3221, at least the portion in contact with the overhead rope 100, is provided with an anti-slip pattern. This design improves the deceleration performance of the rolling support wheel 322.

[0059] Among them, such as Figure 1-3 As shown, the first link 31 and the second link 321 are both located at one end of the rolling support wheel 322 along the axial direction, and the deceleration rod 21 is located at the other end of the rolling support wheel 322 along the axial direction. The deceleration element 22 is located between the first link 31 and the deceleration rod 21. It can be understood that along the axial direction of the rolling support wheel 322, the first link 31 and the second link 321 are spaced apart from the deceleration rod 21, and the rolling support wheel 322 and the deceleration rod 21 are not directly connected. After locking the locking body 1 to the overhead rope 100, when the overhead rope 100 is to be threaded between the two rolling support wheels 322 of the rolling support wheel assembly 32, first insert the overhead rope 100 into the gap between the first connecting rod 31 and the deceleration rod 21 from the side of the rolling support wheel 322 close to the deceleration rod 21 in the axial direction. Then, move the overhead rope 100 to the gap between the two rolling support wheels 322 of the rolling support wheel assembly 32, so that the overhead rope 100 is distributed in the annular limiting groove 3221 of the rolling support wheel 322, so as to realize that the overhead rope 100 is threaded between the two rolling support wheels 322 of the rolling support wheel assembly 32 and rolls with the two rolling support wheels 322 of the rolling support wheel assembly 32.

[0060] In order to further improve the deceleration performance of the high-altitude operation lock in case of accidental slippage during the process of workers moving from the higher end to the lower end of the overhead rope 100, such as... Figure 1 , Figure 2 and Figure 4As shown, the high-altitude operation lock also includes two opposing blocking components. The blocking components include a stop bar 4 rotatably connected to the inner peripheral wall of the lock body 1, and a third torsion spring disposed on the lock body 1. The two ends of the third torsion spring are respectively connected to the lock body 1 and the stop bar 4. The two stop bars 4 are configured to open under the action of external force to form a channel for the overhead rope 100 to pass through. The elastic restoring force of the third torsion spring can drive the two stop bars 4 to close and block the overhead rope 100. Specifically, after the locking body 1 is locked onto the overhead rope 100, the locking body 1 is tilted and placed on the overhead rope 100, and the stop bar 4 is also placed on the overhead rope 100. During the process of the operator moving the locking body 1 along the extension direction of the overhead rope 100, the stop bar 4 slides on the overhead rope 100. The friction between the stop bar 4 and the overhead rope 100 is small and will not affect the operator's progress. When the operator accidentally slips while moving from the higher end to the lower end of the overhead rope 100, the force between the stop bar 4 and the overhead rope 100 increases. The force exerted by the overhead rope 100 on the stop bar 4 causes the two stop bars 4 to open, allowing the overhead rope 100 to pass through the stop bars 4. After the overhead rope 100 passes through the stop bars 4, the elastic restoring force of the third torsion spring causes the two stop bars 4 to close again, limiting the distribution position of the overhead rope 100 within the locking body 1.

[0061] Preferably, the stop bar 4 is cylindrical. This reduces the contact area with the overhead rope 100, thereby reducing friction between the stop bar 4 and the overhead rope 100, making it easier for the operator to move the locking body 1 along the extension direction of the overhead rope 100.

[0062] Preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, the open portions of the two baffles 4 are directly opposite the central region of the rolling support wheel 322 along the axial direction. This arrangement facilitates the passage of the overhead rope 100 through the channel formed by the open portions of the two baffles 4.

[0063] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the high-altitude work lock also includes two opposing second deceleration components, which are located away from the deceleration mechanism relative to the blocking component. The second deceleration components include a fastening member 5 rotatably connected to the inner peripheral wall of the lock body 1, and a fourth torsion spring disposed on the lock body 1. The two ends of the fourth torsion spring are respectively connected to the lock body 1 and the fastening member 5. The two fastening members 5 are configured to be able to fasten together under the action of external force to form a receiving cavity for accommodating the overhead rope 100. The elastic restoring force of the fourth torsion spring can drive the two fastening members 5 away from each other and make the opening 51 of the fastening member 5 face the stop bar 4. Specifically, when the force applied by the overhead rope 100 to the stop bar 4 causes the two stop bars 4 to open, allowing the overhead rope 100 to pass through the stop bars 4, the overhead rope 100 contacts the two fastening members 5. The force applied to the fastening members 5 can cause the two fastening members 5 to fasten together to form a receiving cavity. The overhead rope 100 is distributed in the receiving cavity and makes frictional contact with the inner sidewall of the fastening members 5, thereby further improving the deceleration effect. If the overhead rope 100 causes the two fastening members 5 to continue to rotate until the two fastening members 5 reopen, or if the friction between the overhead rope 100 and the fastening members 5 causes the fastening members 5 to fail, the overhead rope 100 will disengage from the fastening members 5 and make frictional contact with the inner sidewall of the locking body 1, which can also further improve the deceleration effect.

[0064] Preferably, the portion of the fastener 5 that contacts the overhead rope 100 has an anti-slip pattern. This design further enhances the deceleration effect.

[0065] More specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the inner peripheral wall of the locking body 1 is also provided with a first resistance limiting groove 111. The first resistance limiting groove 111 is distributed between the two second deceleration components and is used to accommodate the overhead rope 100. Specifically, if the overhead rope 100 drives the two fastening members 5 to continue rotating until the two fastening members 5 reopen, or if the overhead rope 100 rubs against the fastening members 5 causing the fastening members 5 to fail, the overhead rope 100 will disengage from the fastening members 5 and be accommodated in the first resistance limiting groove 111, making frictional contact with the inner sidewall of the first resistance limiting groove 111, thereby further improving the deceleration effect.

[0066] Preferably, the inner wall of the first resistance limiting groove 111, at least the portion in contact with the overhead rope 100, is provided with anti-slip patterns. This design can further improve the deceleration effect.

[0067] More preferably, the portion of the latch body 1 with the first resistance limiting groove 111 is the first latch segment, and the portion of the latch body 1 without the first resistance limiting groove 111 is the second latch segment, with the outer diameter of the second latch segment being larger than that of the first latch segment. This configuration improves the structural strength of the latch body 1, thereby extending its service life.

[0068] Among them, such as Figure 1 , Figure 2 and Figure 4 As shown, the locking body 1 includes a locking ring 11, a locking rod 12 rotatably connected to the locking ring 11, and an internally threaded sleeve 13 slidably fitted onto the locking rod 12. The free end of the locking ring 11 is provided with an external thread 112, and the internally threaded sleeve 13 is used for threaded connection with the external thread 112 on the locking ring 11. This arrangement allows the locking body 1 to be locked onto the overhead rope 100.

[0069] Preferably, such as Figure 4 As shown, the free end of the locking ring 11 is provided with a limiting groove 113, and the free end of the locking rod 12 is provided with a limiting protrusion 121, which can engage with the limiting groove 113. Specifically, when locking the locking ring 11 and the locking rod 12, first rotate the locking rod 12 so that the limiting protrusion 121 engages with the limiting groove 113, and then screw the internal thread sleeve 13 to connect with the external thread 112 of the locking ring 11, so as to lock the locking ring 11 and the locking rod 12.

[0070] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the locking ring 11 body is also provided with a collar 14. The collar 14 is used to connect to the safety rope worn by the worker.

[0071] The present invention also provides a method for using a high-altitude work lock, for use with the aforementioned high-altitude work lock, the method of using the high-altitude work lock comprising:

[0072] Lock the buckle body 1 to the overhead rope 100, so that the buckle body 1 slides on the overhead rope 100.

[0073] The overhead rope 100 is threaded through two rolling support assemblies 3, allowing the rolling support assemblies 3 to roll in engagement with the overhead rope 100, and the deceleration component 22 to be suspended above the overhead rope 100 and the two rolling support assemblies 3. Specifically, the overhead rope 100 is inserted into the gap between the first connecting rod 31 and the deceleration rod 21 from the axial direction of the rolling support wheel 322 near the deceleration rod 21; the overhead rope 100 is moved and positioned in the gap between the two rolling support wheels 322 of the rolling support wheel assembly 32; and the overhead rope 100 is placed in the annular limiting groove 3221 of the rolling support wheel 322. This achieves the goal of threading the overhead rope 100 through the gap between the two rolling support wheels 322 of the rolling support wheel assembly 32 and allowing it to roll in engagement with the two rolling support wheels 322 of the rolling support wheel assembly 32.

[0074] When the locking body 1 is subjected to an external force and moves downward, the deceleration component 22 moves downward synchronously and presses against the overhead rope 100, while the two rolling support components 3 move away from each other. This achieves deceleration. Specifically, during the process of the deceleration component 22 moving downward synchronously and pressing against the overhead rope 100, it simultaneously drives the first torsion spring and the second torsion spring to undergo elastic deformation, which increases the angle between the two first connecting rods 31, moves the two rolling support wheel sets 32 away from each other, and increases the included angle between the first connecting rod 31 and the second connecting rod 321. As a result, the two rolling support wheels 322 of the rolling support wheel set 32 ​​can still roll and cooperate with the overhead rope 100, and the interaction force between the two rolling support wheels 322 of the rolling support wheel set 32 ​​and the overhead rope 100 increases, increasing the mutual friction force between them. This allows the rolling support wheel set 32 ​​to also play a certain deceleration role to achieve deceleration.

[0075] When the external force is removed, the elastic restoring force of the first torsion spring causes the deceleration component 22 to be suspended above the overhead rope 100 and the two rolling support components 3, and causes the two rolling support components 3 to move closer to each other.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
