Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for high-altitude operations, and in particular to a flexible fall arrestor that is easy to install. Background Technology

[0002] Currently, in high-altitude operations such as construction, power, and bridge construction, in addition to common rigid guide rails such as "I-beams" and "T-beams", there are also flexible guide rails made of thick steel cables and thick wire cables. Flexible fall arresters are an important device used to ensure the safety of workers on flexible guide rails.

[0003] Traditional fall arresters mainly employ trigger-based mechanical locking structures, such as using centrifugal force to trigger the locking mechanism or utilizing spring-driven brake blocks to achieve fall prevention. However, due to their complex structure, these fall arresters tend to be bulky. When used on flexible guide rails, they are prone to numerous drawbacks, including response delays, poor braking smoothness, complex structure and high maintenance costs, and limited applicability. They also fail to lock in time, posing safety hazards. Utility Model Content

[0004] The main purpose of this invention is to provide a flexible fall arrestor that is easy to install, with a simple structure, rapid response, and quick installation.

[0005] To achieve the above objectives, this utility model proposes a flexible fall arrestor that is easy to install, comprising a shell and a connector rotatably connected to the shell. The bottom of the shell is provided with a hook facing the connector, and a locking part is formed by clamping the connector and the hook. The shell is provided with a rotating shaft facing the connector.

[0006] The connector includes a connecting part rotatably connected to the rotating shaft, an extension part connected to the connecting part, and a mounting part located at the end of the extension part away from the connecting part and having a mounting hole. One side of the connecting part is provided with a fall-prevention part, and the other side is provided with a release part. The fall-prevention part is connected to the extension part, and the radius of the connecting part gradually decreases along the rotation direction from the fall-prevention part to the release part.

[0007] In one embodiment of this application, the connector is connected to one side of the housing, and a mating member is rotatably connected to the other side of the housing. A stabilizing member parallel to the top of the housing is connected between the connector and the mating member, and the stabilizing member is connected to the top of the mating member.

[0008] In one embodiment of this application, the mating member has a reinforcing portion relative to the stabilizing member and a protective portion relative to the outer shell, wherein the reinforcing portion is parallel to the extension portion;

[0009] The structure of the protective part is the same as that of the connecting part.

[0010] In one embodiment of this application, the extension portion protrudes towards the connecting portion with a connecting block, and the release portion is located on the side of the connecting block away from the extension portion.

[0011] In one embodiment of this application, the outer shell includes at least two shells with the same structure and arranged alternately, and a hook is provided on one side of the bottom of the shell and a clearance groove is provided on the other side;

[0012] When the two housings are connected, the hook of one housing is provided with a clearance groove corresponding to the other housing.

[0013] In one embodiment of this application, one of the outer casings is provided with a rotating shaft, and the other outer casing is provided with a mating shaft at the end facing the connecting block away from the rotating shaft, and the connecting block is rotatably connected to the mating shaft.

[0014] By adopting the above technical solution, this utility model has the following advantages:

[0015] To facilitate the installation of the fall arrestor on the flexible track, this application may structurally include a housing and a connector. The connector is used to install and connect the user's lanyard, while the bottom of the housing is provided with a hook. The cylindrical inner groove formed by the hook allows the housing to be quickly fixed to the lanyard, achieving the effect of quick installation and positioning of the fall arrestor. The cylindrical inner window formed by the clamping between the connector and the hook can also be called a locking part for locking the flexible guide rail. A pivot is provided between the housing and the connector to allow the connector to rotate freely.

[0016] The connector itself can be divided into a connecting part, an extension part, and a mounting part. The mounting part has mounting holes for quick installation of the lanyard to the user. The connecting part is rotatably connected to a shaft inside the housing. One side of the connecting part has a fall arrestor and the other side has a release part. When the connecting part rotates, its radius gradually decreases along the direction from the fall arrestor to the release part. When it is necessary to install or remove the fall arrestor, the end of the connecting part facing the release part can be rotated to the bottom of the release part. At this time, the release part is completely aligned with the locking part, and the gap between the hook and the connecting part is sufficient to allow the cable to pass through, enabling quick installation and locking.

[0017] Meanwhile, the radius of the connecting part gradually increases along the rotation direction from the release part to the fall arrestor. When the fall arrestor is in use, the fall arrestor is vertically downward after installation. When a user falls while carrying the fall arrestor, because the radius of the fall arrestor gradually increases, the force of the user's fall acts on the mounting part, forms a lever through the extension part, and is transmitted to the fall arrestor. The fall arrestor can quickly clamp the cable, achieving a quick release effect. Through the above structure, the fall arrestor can achieve the purpose of simple structure and good fall arrest effect. Attached Figure Description

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Reference Figures 1 to 4 To achieve the above objectives, this utility model proposes a flexible fall arrestor that is easy to install, including a shell 1 and a connector 2 rotatably connected to the shell 1. The bottom of the shell 1 is provided with a hook 12 facing the connector 2, and a locking part is formed by clamping the connector 2 and the hook 12. The shell 1 is provided with a rotating shaft facing the connector 2.

[0028] The connector 2 includes a connecting part 21 rotatably connected to the rotating shaft, an extension part 3 connected to the connecting part 21, and a mounting part 4 located at one end of the extension part 3 away from the connecting part 21 and having a mounting hole. A fall-prevention part 22 is provided on one side of the connecting part 21, and a release part 23 is provided on the other side. The fall-prevention part 22 is connected to the extension part 3. The radius of the connecting part 21 gradually decreases along the rotation direction from the fall-prevention part 22 to the release part 23.

[0029] To facilitate the installation of the fall arrestor on the flexible track, this application may structurally include a housing 1 and a connector 2. The connector 2 is used to install and connect the user's lanyard, while the bottom of the housing 1 is provided with a hook 12. Through the cylindrical inner groove formed by the hook 12, the housing 1 can be quickly fixed to the lanyard, achieving the effect of quick installation and positioning of the fall arrestor. The cylindrical inner window formed by the clamping between the connector 2 and the hook 12 can also be called a locking part for locking the flexible guide rail. A pivot is provided between the housing 1 and the connector 2 to allow the connector 2 to rotate freely.

[0030] The connector 2 itself can be divided into a connecting part 21, an extension part 3, and a mounting part 4. The mounting part 4 has a mounting hole for quick installation of the lanyard connected to the user. The connecting part 21 is rotatably connected to the rotating shaft inside the outer casing 1. One side of the connecting part 21 has a fall arrestor 22, and the other side has a release part 23. When the connecting part 21 rotates, its radius gradually decreases along the direction from the fall arrestor 22 to the release part 23. When it is necessary to install or remove the fall arrestor, the end of the connecting part 21 facing the release part 23 can be rotated to the bottom of the release part 23. At this time, the release part 23 is completely aligned with the locking part, and the gap between the hook 12 and the connecting part 21 is sufficient to allow the cable to pass through or through, enabling quick installation and locking.

[0031] Meanwhile, the radius of the connecting part 21 gradually increases along the rotation direction from the release part 23 to the fall arresting part 22. When the fall arresting device is in use, the fall arresting part 22 is vertically downward after installation. When a user falls while carrying the fall arresting device, because the radius of the fall arresting part 22 gradually increases, the force of the user's fall acts on the mounting part 4 and is transmitted to the fall arresting part 22 through the extension part 3 to form a lever. The fall arresting part 22 can quickly clamp the cable and achieve the effect of quick placement. Through the above structure, the fall arresting device can achieve the purpose of simple structure and good fall arresting effect.

[0032] See also Figures 1 to 4 Connector 2 is connected to one side of housing 1, and mating part 5 is rotatably connected to the other side of housing 1. A stabilizing part 6 parallel to the top of housing 1 is connected between connector 2 and mating part 5. The stabilizing part 6 is connected to the top of mating part 5.

[0033] By adding an additional fitting 5 to the outer casing 1, the connection of the user's lanyard can be made more stable. Furthermore, a stabilizing element 6 is provided between the connecting element 2 and the fitting 5 to connect the two, further enhancing the overall stability of the fall arrester's structure.

[0034] See also Figures 1 to 2 The mating part 5 is provided with a reinforcing part 51 relative to the stabilizing part 6 and a protective part 52 relative to the outer shell 1. The reinforcing part 51 is parallel to the extension part 3.

[0035] The structure of the protective part 52 is the same as that of the connecting part 21.

[0036] The mating part 5 is reinforced by a reinforcing part 51 to increase its strength. The mating part 5 has the same structure as the protective part 52 and the connecting part 21 provided with the outer shell 1. This allows the mating part 5 and the connecting part 2 to have the same movement path, which increases the number of connection points between the fall arrester and the cable during fall arrest, thus ensuring the stability of the fall arrest effect.

[0037] See also Figures 1 to 2 The extension portion 3 has a connecting block 31 protruding towards the connecting portion 21, and the release portion 23 is located on the side of the connecting block 31 away from the extension portion 3.

[0038] The connecting block 31 is located on the side of the extension 3 away from the fall arrestor 22. By using the connecting block 31, the structural strength of the entire connector 2 can be improved when the fall arrestor 22 is in place. The connecting block 31 can effectively protect the entire connector 31, effectively achieve fast and stable fall arrest, and at the same time prevent the connecting block 31 from being damaged during operation.

[0039] See also Figures 1 to 4 The outer casing 1 includes at least two casings 11 with the same structure and arranged in an alternating manner. One side of the bottom of the casing 11 is provided with a hook 12 and the other side is provided with a clearance groove.

[0040] When the two housings 11 are connected, the hook 12 of one housing 11 is set to correspond to the clearance groove of the other housing 11.

[0041] The outer shell 1 is composed of two shells 11 with similar structures. The hooks 12 of the two shells 11 are staggered. The two hooks 12 staggered in the relief groove can form a more stable connection structure, which can effectively prevent the hooks 12 from loosening. The above structure can effectively ensure the connection stability of the fall arrestor and prevent the fall arrestor from loosening.

[0042] See also Figures 1 to 2 One outer shell 1 is provided with a rotating shaft, and the other outer shell 1 is provided with a mating shaft at the end of the connecting block 31 away from the rotating shaft. The connecting block 31 is rotatably connected to the mating shaft.

[0043] The rotating shaft is connected to the connecting part 21, while the mating shaft is connected to the side of the connecting block 31 away from the rotating shaft. There may be a height difference between the rotating shaft and the mating seat. Because the protective part 52 and the connecting part 21 have the same structure, when a fall occurs, the hook 12 of the housing 11 on the mating shaft will move towards the cable under the action of the connecting part 21. The anti-fall part 22 abuts against one side of the cable, and the hook 12 of the housing 11 abuts against the other side of the cable, which can effectively improve the anti-fall effect. At the same time, when the connecting part 2 moves towards the release part 23, the housing 1 with the mating shaft will move away from the cable, achieving the effect of releasing the cable. After the other end of the cable moves towards the bottom of the release part 23, the locking part can be expanded, and the cable can be quickly removed. Through the above structure, the anti-fall effect can be improved, and the anti-fall device itself can be easily disassembled and assembled, which can effectively improve the user experience.
