Description

Technical Field

[0001] The present application belongs to the field of aerial work equipment, and more specifically, to a dual-purpose anti-dislocation and anti-fall guide rail ladder. Background Art

[0002] Due to the high height of high-voltage power towers, the upward climbing operation of operators and maintenance personnel has become an indispensable part of transmission line maintenance, but it is also accompanied by huge safety risks. Especially in situations where frequent climbing up and down or long-term high-altitude operations are required, how to ensure the safety of operators is a problem that must be solved; although the traditional ladder design can meet the basic climbing needs, it has obvious deficiencies in fall prevention. For example, the anti-fall guide rail designed on the traditional ladder can only be applied to a single type of fall arrester, which greatly limits the use of the ladder in multiple occasions. In addition, a single anti-fall guide rail is often set on the traditional ladder, which is obviously not adaptable for operators with different working habits. Finally, since the operator's waist is relatively high at the beginning, and the hanging rope of the fall arrester is connected to the safety belt, therefore, when the fall arrester is just installed on the guide rail, because there is no upward traction and no pulling force to lock the fall arrester, the anti-fall guide rail of the traditional ladder is often easy to cause the fall arrester to fall off from the initial position of the anti-fall guide rail and cause damage to the operator's feet. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a dual-purpose anti-dislocation and anti-fall guide rail ladder to solve the technical problems in the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is to provide a dual-purpose anti-dislocation and anti-falling guide rail ladder, comprising:

[0005] longitudinal beams, forming a T-shaped guide;

[0006] A circular guide rail, parallel to the T-shaped guide rail and arranged on the left and right sides of the longitudinal beam, the circular guide rail being connected to the longitudinal beam via a cross bar used as a footrest;

[0007] A blocking member, rotatably connected to the circular guide rail via a rotating shaft parallel to the circular guide rail;

[0008] A torsion spring, which is connected between the blocking member and the circular guide rail and has one end of the blocking member away from the rotating shaft, can automatically interfere with the moving path of the fall arrester relative to the circular guide rail.

[0009] Optionally, the circular guide rail is provided with a notch for the fall arrester to be installed on the circular guide rail, and a stop pin abutting against the blocking member is connected to the end surface of the circular guide rail used for forming the notch;

[0010] The distance between the blocking member and the circular guide rail in the extending direction of the circular guide rail is smaller than the minimum distance by which the fall arrester can be separated from the circular guide rail from the notch.

[0011] Optionally, the blocking member is an extended structure having the same cross-sectional shape as the circular guide rail.

[0012] Optionally, the circular guide rail forms a plate portion and cylindrical portions connected to both sides of the plate portion, and end surfaces of the two cylindrical portions used to form the notch both form shaft holes for mounting the rotating shaft.

[0013] Optionally, the axial holes are formed on both side end surfaces of the blocking member along its own extension direction.

[0014] Optionally, the blocking member and the notch are matched in length in the extension direction of the circular guide rail, and the plate portion is provided with notches for the torsion spring to extend to opposite sides of the blocking member.

[0015] Optionally, the dual-purpose anti-dislocation and anti-fall guide rail ladder further comprises an additional beam having the same cross-sectional shape as the longitudinal beam and an additional guide rail having the same cross-sectional shape as the circular guide rail;

[0016] The additional guide rail is connected to the circular guide rail and cooperates with the circular guide rail to form the notch.

[0017] Optionally, the additional guide rail and the circular guide rail are connected via a connecting plate, and the connecting plate is provided with an avoidance cavity for the blocking member and the torsion spring to move.

[0018] Optionally, the dual-purpose anti-dislocation and anti-fall guide rail ladder also includes a first connecting plate for connecting a plurality of the longitudinal beams in sequence and a second connecting plate for connecting a plurality of the circular guide rails in sequence.

[0019] The beneficial effect of the dual-purpose anti-dislocation anti-falling guide rail ladder provided by the present application is that: compared with the prior art, in the dual-purpose anti-dislocation anti-falling guide rail ladder provided by the present application, the T-shaped guide rail and the circular guide rail formed by the longitudinal beam can be used to install different types of anti-falling devices respectively, which obviously expands the use scenario of the dual-purpose anti-dislocation anti-falling guide rail ladder in the present application. In addition, since the circular guide rail is arranged in parallel on the left and right sides of the longitudinal beam, it can be well adapted to operators with different operating habits and has good adaptability. Finally, in the present application, a blocking member is rotatably connected on the circular guide rail, and the torsion spring arranged between the blocking member and the circular guide rail can make the blocking member away from the end of the rotating shaft automatically interfere with the moving path of the anti-falling device relative to the circular guide rail. In this way, when the anti-falling device is installed on the circular guide rail, since its moving path relative to the circular guide rail is limited by the blocking member, it can be well avoided from detaching from the circular guide rail, avoiding accidental injury to the operator at the beginning, and having a good safety protection effect. In summary, the dual-purpose anti-dislocation and anti-fall guide rail ladder provided by the present application has a far superior effect in preventing falls than the prior art.

[0032] Please also read Figures 1 to 6 Now, a dual-purpose anti-dislocation anti-falling guide rail ladder provided in an embodiment of the present application is described. The dual-purpose anti-dislocation anti-falling guide rail ladder comprises a longitudinal beam 101, a circular guide rail 103, a blocking member 105 and a torsion spring 107. Among them:

[0033] The longitudinal beam 101 forms a T-shaped guide rail 102, and the circular guide rail 103 is parallel to the T-shaped guide rail 102 and is arranged on the left and right sides of the longitudinal beam 101. The circular guide rail 103 is connected to the longitudinal beam 101 through a cross bar 104 used as a footrest, and the blocking member 105 is rotatably connected to the circular guide rail 103 through a rotating shaft 106 parallel to the circular guide rail 103. The torsion spring 107 is connected between the blocking member 105 and the circular guide rail 103 and enables the end of the blocking member 105 away from the rotating shaft 106 to automatically interfere with the moving path of the fall arrester 201 relative to the circular guide rail 103.

[0034] According to the above structure provided in the present embodiment, in the dual-purpose anti-dislocation anti-falling guide rail ladder provided in the present embodiment, the T-shaped guide rail 102 and the circular guide rail 103 formed by the longitudinal beam 101 can be used to install different types of fall arresters 201 respectively, which obviously expands the use scenario of the dual-purpose anti-dislocation anti-falling guide rail ladder in the present embodiment. In addition, since the circular guide rail 103 is arranged in parallel on the left and right sides of the longitudinal beam 101, it can be well adapted to operators with different operating habits and has good adaptability. Finally, in the present embodiment, a blocking member 105 is rotatably connected to the circular guide rail 103, and a torsion spring 107 arranged between the blocking member 105 and the circular guide rail 103 can make the end of the blocking member 105 away from the rotating shaft 106 automatically interfere with the moving path of the fall arrester 201 relative to the circular guide rail 103. In this way, when the fall arrester 201 is installed on the circular guide rail 103, since its moving path relative to the circular guide rail 103 is limited by the blocker, it can well avoid being separated from the circular guide rail 103, and has a good safety protection effect. In summary, the dual-purpose anti-dislocation anti-falling guide rail ladder provided by the present application has a far better use effect than the prior art in terms of anti-falling.

[0035] It should be noted that when the fall arrester 201 is installed on the dual-purpose anti-dislocation anti-falling guide rail ladder provided in this embodiment, the blocking member 105 needs to be rotated relative to the circular guide rail 103 in advance, so that the fall arrester 201 can be smoothly installed on the circular guide rail 103. When the fall arrester 201 is installed in place, the blocking member 105 automatically resets under the action of the torsion spring 107, which can well achieve the technical effect of preventing the fall arrester 201 from slipping off the circular guide rail 103 and falling at the beginning.

[0036] In another embodiment of the present application, please refer to Figures 1 to 6The circular guide rail 103 is provided with a notch 108 for the fall arrester 201 to be installed on the circular guide rail 103. The end surface of the circular guide rail 103 used to form the notch 108 is connected with a stopper pin 109 that abuts against the blocking member 105. The distance between the blocking member 105 and the circular guide rail 103 in the extending direction of the circular guide rail 103 is less than the minimum distance that the fall arrester 201 can be separated from the circular guide rail 103 from the notch 108. According to the above structure provided in this embodiment, by providing the notch 108 on the circular guide rail 103, the fall arrester 201 can be installed on the circular guide rail 103 from the notch 108 of the circular guide rail 103, without having to be installed on the circular guide rail 103 from the end of the circular guide rail 103, which has a more flexible installation effect than the prior art.

[0037] In another embodiment of the present application, please refer to Figures 1 to 6 , the blocking member 105 is an extended structure with the same cross-sectional shape as the circular guide rail 103. According to the above structure provided in this embodiment, the blocking member 105 is set as an extended structure with the same cross-sectional shape as the circular guide rail 103, and the portion of the circular guide rail 103 used for processing the notch 108 can be used as the blocking member 105, which is conducive to reducing the production and manufacturing cost of the dual-purpose anti-dislocation and anti-falling guide rail ladder provided in this embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 6 The circular guide rail 103 is formed with a plate portion 110 and cylindrical portions 111 connected to both sides of the plate portion 110. The end surfaces of the two cylindrical portions 111 used to form the notch 108 are formed with shaft holes 112 for installing the rotating shaft 106. According to the above structure provided in this embodiment, the circular guide rail 103 adopts the above structure to facilitate machining the shaft holes 112 for accommodating the rotating shaft 106 on both sides of the cylindrical portions 111, so that the blocking member 105 in this embodiment has better flexibility during installation, which is far superior to the prior art.

[0039] In another embodiment of the present application, please refer to Figures 1 to 6 The blocking member 105 has shaft holes 112 formed on both side end surfaces along its extension direction. According to the above structure provided in this embodiment, by machining the shaft holes 112 on both side end surfaces of the blocking member 105, the blocking member 105 in this embodiment can have further flexibility during installation.

[0040] In another embodiment of the present application, please refer to Figures 1 to 6 The lengths of the blocking member 105 and the notch 108 in the extending direction of the circular guide rail 103 are adapted, and the plate portion 110 is provided with notches 113 for the torsion spring 107 to extend to opposite sides of the blocking member 105. According to the above structure provided in this embodiment, by setting the length of the blocking member 105 to match the length of the notch 108, the fall arrester 201 can be further prevented from being separated from the circular guide rail 103.

[0041] In another embodiment of the present application, please refer to Figures 1 to 6 The dual-purpose anti-dislocation anti-falling guide rail ladder also includes an additional beam 114 with the same cross-sectional shape as the longitudinal beam 101 and an additional guide rail 115 with the same cross-sectional shape as the circular guide rail 103. The additional guide rail 115 is connected to the circular guide rail 103 and cooperates with the circular guide rail 103 to form a notch 108. According to the above structure provided in this embodiment, by providing the additional beam 114 and the additional guide rail 115, it is possible to avoid directly processing the notch 108 for installing the fall arrester 201 on the original circular guide rail 103, which is conducive to maintaining a good structural strength of the circular guide rail 103.

[0042] In another embodiment of the present application, please refer to Figures 1 to 6 The additional guide rail 115 and the circular guide rail 103 are connected by a connecting plate 116, and an avoidance cavity 117 for the blocking member 105 and the torsion spring 107 to move is provided on the connecting plate 116. According to the above structure provided in this embodiment, connecting the additional guide rail 115 and the circular guide rail 103 by the connecting plate 116 not only has better connection stability, but also can be more suitable for the activity space of the blocking member 105 and the torsion spring 107.

[0043] In another embodiment of the present application, please refer to Figures 1 to 6 The dual-purpose anti-dislocation anti-falling guide rail ladder also includes a first connecting plate 118 for connecting a plurality of longitudinal beams 101 in sequence and a second connecting plate 119 for connecting a plurality of circular guide rails 103 in sequence. According to the above structure provided in this embodiment, the longitudinal beams 101 and the circular guide rails 103 in this embodiment can be conveniently extended through the first connecting plate 118 and the second connecting plate 119, which is conducive to further expanding the scope of use of the dual-purpose anti-dislocation anti-falling guide rail ladder provided in this embodiment.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
