Abstract
Description
Technical Field
[0001] This utility model relates to the field of commutator technology, and in particular to a high-strength, fall-proof commutator. Background Technology
[0002] In high-altitude operations (such as the maintenance of power transmission towers, communication towers, and wind power equipment), workers rely on fall arrest systems for safety. Rail-mounted fall arrest systems are widely used due to their high efficiency and stability, and mainly consist of I-beam aluminum alloy rails, fall arresters, fixing hardware, and a commutator. The commutator guides the fall arrester smoothly between rails in different directions to adapt to complex working environments.
[0003] Existing commutators have an internal rotating connection with a reversing section. By aligning the reversing section with the track into which the fall arrestor enters, the fall arrestor can enter. By freely rotating the reversing section, the fall arrestor can be aligned with the track to be switched. However, the reversing section in most existing commutators rotates freely. Users need to continuously operate the reversing section to align with the track when switching, which makes the commutator very inconvenient to use. At the same time, the commutator itself is prone to damage. Utility Model Content
[0004] The main purpose of this utility model is to provide a high-strength anti-fall commutator, which aims to improve the overall structural strength, enable the commutator to self-lock, and achieve fast and stable commutation operation.
[0005] To achieve the above objectives, this utility model proposes a high-strength anti-fall commutator, including a connecting assembly with a commutation cavity and a commutation track passing through the commutation cavity. The outer periphery of the connecting assembly has multiple connecting parts that communicate with the commutation cavity, protruding in a direction opposite to the commutation track. The connecting assembly has a limiting groove at the bottom of the commutation cavity. The limiting groove has a locking groove facing each of the two connected parts. The commutation track has an adjustable locking element facing the locking groove.
[0006] The adjustable locking member includes a fixing part connected to the limiting groove and locking parts connected to both sides of the fixing part, wherein the width of the fixing part is equal to the width of the limiting groove.
[0007] In one embodiment of this application, the reversing track includes a track body disposed in the reversing cavity and a locking component disposed on the side of the connecting component away from the reversing cavity. The locking component and the track body are coaxially arranged and connected to each other, and the adjustable locking member is disposed on the end face of the locking component facing the connecting component.
[0008] In one embodiment of this application, the outer periphery of the locking component is provided with a sealing structure for the connecting component, and the outer periphery of the sealing structure is provided with a plurality of anti-slip teeth.
[0009] In one embodiment of this application, the connecting component has at least two limiting slots, the two limiting slots are symmetrically arranged along the central axis, the connecting component has a protective part opposite to the two limiting slots, and the adjustable locking member passes through the limiting slot and is connected to the protective part.
[0010] In one embodiment of this application, the protective portion encloses and forms a stabilizing groove, and the track body is provided with a stabilizing portion relative to the stabilizing groove, the stabilizing portion being slidably connected to the stabilizing groove.
[0011] In one embodiment of this application, the locking part is a locking piece, and at least two locking parts are provided, with a return spring provided between the two locking parts.
[0012] In one embodiment of this application, the connecting portion is provided with a mounting structure facing the reversing track, and the end of the mounting structure away from the connecting component is provided with a plurality of mounting holes at intervals.
[0013] By adopting the above technical solution, this utility model has the following advantages:
[0014] The entire structure of the commutator includes a connecting assembly that serves as the outer shell and a commutation rail located within the connecting assembly. By providing a commutation cavity that wraps around the commutation rail, the connecting assembly can effectively prevent the fall arrestor inside the commutator from derailing before it is properly connected to the external rail, thus effectively protecting the user and preventing potential safety hazards.
[0015] The outer periphery of the connecting assembly is provided with multiple connecting parts that connect to the commutation cavity. The connecting parts are used to connect to the external guide rail, allowing the user to use the commutator to enter the commutation guide rail for commutation. The multiple connecting parts are generally in pairs, so that the entire commutator can pass directly when commutation is not required, which can improve the user experience.
[0016] The bottom of the reversing cavity is provided with a limiting groove, which is arc-shaped and located between two connecting parts. A locking groove, also arc-shaped, is provided opposite the connecting parts. The radius of the locking groove is greater than the width of the limiting groove. An adjustable locking element is provided on the reversing guide rail opposite the limiting groove. Structurally, the adjustable locking element includes a fixing part and a locking part. The fixing part is a high-strength arc-shaped structure facing the limiting groove, and its width is less than or equal to the width of the limiting groove. The locking part is an arc-shaped spring piece connected to both ends of the fixing part. The components together form a cylindrical structure. When reversing is not required, the adjustable locking element passes through the locking groove and locks the entire structure. This structure allows the commutator to be locked when reversing is not needed. When reversing is required, the locking part will deform and the fixing part can pass through the limiting groove by force when the reversing is completed. After the reversing is completed, the locking part, which acts as a spring, returns to its original shape and locks the reversing track again. This structure allows the fall-proof commutator to have strong structural strength while allowing the commutator to be locked freely. Attached Figure Description

[0024] 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
[0025] 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.
[0026] Reference Figures 1 to 4 To achieve the above objectives, this utility model proposes a high-strength anti-fall commutator, including a connecting component 1 with a commutation cavity 12 and a commutation track 2 passing through the commutation cavity 12. The outer periphery of the connecting component 1 has multiple connecting parts 11 protruding along the direction away from the commutation track 2 and communicating with the commutation cavity 12. The connecting component 1 has a limiting groove 14 at the bottom of the commutation cavity 12. The limiting groove 14 has a locking groove 15 facing each of the two connected connecting parts 11. The commutation track 2 has an adjustable locking element 5 facing the locking groove 15.
[0027] The adjustable locking member 5 includes a fixing part 51 connected to the limiting groove 14 and a locking part 52 connected to both sides of the fixing part 51. The width of the fixing part 51 is equal to the width of the limiting groove 14.
[0028] The entire structure of the commutator includes a connecting component 1 as the outer shell and a commutation rail 2 disposed within the connecting component 1. The connecting component 1, by providing a commutation cavity 12 that surrounds the commutation rail, can effectively prevent the fall arrestor inside the commutator from derailing before it is properly connected to the external rail, thus effectively protecting the user and preventing safety hazards.
[0029] The outer periphery of the connecting component 1 is provided with multiple connecting parts 11 that are connected to the commutation cavity 12. The connecting parts 11 are used to connect to the external guide rail, so that the user can use the commutator to enter the commutation guide rail through the guide rail for commutation. The multiple connecting parts 11 are generally in pairs, so that the entire commutator can pass directly when commutation is not required, which can improve the user experience.
[0030] The bottom of the reversing cavity 12 is provided with a limiting groove 14, which is arc-shaped and located between the two connecting parts 11. A locking groove 15 is provided opposite the connecting parts 11, and the locking groove 15 is circular with a radius greater than the width of the limiting groove 14. An adjustable locking element 5 is provided opposite the limiting groove 14 to the reversing guide rail. The adjustable locking element 5 structurally includes a fixing part 51 and a locking part 52. The fixing part 51 is a high-strength arc-shaped structure facing the limiting groove 14, and its width is less than or equal to the width of the limiting groove 14. The locking part 52 is an arc-shaped spring piece connected to the fixing part 51. At both ends of 1, the fixing part 51 and the locking part 52 together form a cylindrical structure. When no reversing is required, the adjustable locking member 5 passes through the locking groove 15 and locks the entire structure. Through this structure, the commutator can be locked when no reversing is required. When reversing is required, by forcefully rotating the reversing track 2, the locking part 52 will deform and the fixing part 51 can pass through the limiting groove 14 on its own. After the reversing is completed, the locking part 52, which is a spring, returns to its original shape and locks the reversing track 2 again. Through this structure, the fall-proof commutator can have strong structural strength while allowing the commutator to be locked freely.
[0031] See also Figures 1 to 4 In one embodiment of this application, the reversing track 2 includes a track body 3 disposed in the reversing cavity 12 and a locking component 4 disposed on the side of the connecting component 1 facing away from the reversing cavity 12. The locking component 4 and the track body 3 are coaxially arranged and connected to each other. An adjustable locking member 5 is disposed on the end face of the locking component 4 facing the connecting component 1.
[0032] The reversing track 2 itself includes a track body 3 and a locking assembly 4. The track body 3 is located inside the reversing cavity 12, and the locking assembly 4 is located at the end of the connecting assembly 1 away from the reversing cavity 12. The two cooperate with each other to clamp the limiting groove 14 and the locking groove 15 between them. The adjustable locking member 5 is located on the locking assembly 4. By rotating the track body 3 or the locking assembly 4, the adjustable locking member 5 can work stably. At the same time, the above structure can effectively enhance the structural strength of the commutator.
[0033] See also Figures 1 to 3 In one embodiment of this application, the outer periphery of the locking component 4 is provided with a sealing structure 41 facing the connecting component 1, and the outer periphery of the sealing structure 41 is provided with a plurality of anti-slip teeth.
[0034] In addition to being connected to the track body 3 via the central shaft, the locking component 4 is connected to the connecting component 1 via a sealing structure 41 on its outer periphery. The sealing structure 41 can protect the adjustable locking component 5 and also provides anti-slip teeth, so that the user can make the commutator work by rotating the locking component 4 itself.
[0035] See also Figures 1 to 4In one embodiment of this application, the connecting component 1 is provided with at least two limiting grooves 14, the two limiting grooves 14 are symmetrically arranged along the central axis, the connecting component 1 is provided with a protective part 13 opposite to the two limiting grooves 14, and the adjustable locking member 5 passes through the limiting groove 14 and is connected to the protective part 13.
[0036] At least two symmetrically arranged limiting slots 14 can increase the contact area between the connecting component 1 and the locking component 4, making both the self-locking of the commutator and the adjustment of the commutator more stable, and preventing damage to the commutator itself. The protection part 13 can be used to guide the adjustable locking member 5 and also protect the adjustable locking member 5 itself.
[0037] See also Figure 1 In one embodiment of this application, the protective part 13 is enclosed to form a stabilizing groove, and the track body 3 is provided with a stabilizing part 31 relative to the stabilizing groove, the stabilizing part 31 being slidably connected to the stabilizing groove.
[0038] The stabilizing groove is wrapped around the track body 3, and the track body 3 is provided with a stabilizing part 31 facing the stabilizing groove. Through the cooperation of the stabilizing groove and the stabilizing part 31, the rotation process of the reversing track 2 can be guaranteed, and the user experience can be optimized.
[0039] See also Figures 2 to 3 In one embodiment of this application, the locking part 52 is a locking piece, and at least two locking parts 52 are provided, with a return spring provided between the two locking parts 52.
[0040] The locking part 52 can be a locking piece or a spring. A return spring is provided between the two locking parts 52 to ensure that after the adjustable locking piece 5 reaches the locking groove 15, the two locking parts 52 can be reset and the commutator is locked. Through the above structure, the self-locking stability of the commutator can be effectively improved, and users can more conveniently adjust the orientation according to their needs.
[0041] See also Figures 1 to 2 In one embodiment of this application, the connecting part 11 is provided with a mounting structure 6 facing the reversing track 2, and the end of the mounting structure 6 away from the connecting component 1 is provided with a plurality of mounting holes at intervals.
[0042] The mounting structure 6 generally consists of two mounting blocks, which are respectively connected to both sides of the connecting part 11. The two mounting blocks are clamped together to form a mounting cavity for fixing the external guide rail. Through the above structure, the stability of the guide rail installation can be guaranteed.
[0043] Multiple mounting holes allow the guide rail and mounting structure 6 to have a longer contact area, ensuring stability when the guide rail and reversing track 2 are aligned, and preventing the fall arrestor from failing to move quickly onto the reversing track 2. Through the above structure, the user experience can be improved.
