Description
Technical Field
[0001] The present application belongs to the field of aerial work equipment, and more specifically, to a longitudinal flexible anti-fall device. Background Art
[0002] In the existing safety equipment for aerial work, the steel cable equipped with the fall arrester is prone to wind swing under the action of wind. This phenomenon not only affects the stability and reliability of the fall arrester, but also may pose a potential threat to the safety of aerial workers. In order to prevent the steel cable from swinging too much due to wind, traditional fall prevention devices generally fix the steel cable with a hook. However, since a notch must be set on the traditional hook for the fall arrester to pass through, the steel cable is also very easy to detach from the hook from the notch set on the hook, causing the hook to lose its limiting effect on the swing of the steel cable and making the entire fall prevention device more unstable under the action of wind. 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 longitudinal flexible anti-falling device to solve the technical problem of poor wind-sway protection effect of steel strands in the prior art.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is to provide a longitudinal flexible fall prevention device, comprising:
[0005] Angle steel;
[0006] Steel strands are arranged parallel to and spaced apart from the angle steels;
[0007] The connection assembly comprises a supporting plate and a wind deflection-proof fixing member connected in a matching manner, wherein the supporting plate is connected to the angle steel, and the wind deflection-proof fixing member forms a connecting piece connected to the supporting plate and a wire wrapping piece connected to the connecting piece and wound around the steel strand;
[0008] The self-locking device forms a slideway for the steel strand and the wire-wrapped sheet to pass through, and the self-locking device is used to form an avoidance groove on the side wall of the slideway for the connecting sheet to pass through.
[0009] Optionally, the wire wrapping sheet forms a spiral wire entry notch in the axial direction of the steel strand, and the maximum spacing of the wire entry notch in the circumferential direction of the steel strand is smaller than the diameter of the steel strand.
[0010] Optionally, the wire covering sheet forms a plurality of wire entry notches which are coaxially arranged and spaced apart along the axial direction of the steel strand.
[0011] Optionally, the wire entry notches formed on the same wire wrapping sheet face the same direction.
[0012] Optionally, a plurality of groups of the connection components are connected to the steel strands at intervals, and the wire entry notches formed on the wire wrapping sheets in adjacent connection components face in opposite directions.
[0013] Optionally, the cross-sectional shape of the wire wrap formed by winding is adapted to the cross-sectional shape of the steel strand so that the wire wrap abuts against the steel strand.
[0014] Optionally, a weight-reducing notch is formed on the connecting piece for reducing the weight of the wind-proof fixing member.
[0015] The beneficial effect of the longitudinal flexible anti-fall device provided by the present application is that compared with the prior art, in the longitudinal flexible anti-fall device provided by the present application, the steel strand is connected to the angle steel through the anti-wind deflection fixing member and the support plate in sequence. Since the anti-wind deflection fixing member has a wire wrapping sheet wound on the steel strand and the self-locking device forms a slideway for the steel strand and the wire wrapping sheet to pass through, there is no need to set a notch on the wire wrapping sheet for the self-locking device to pass through and a stable connection can be formed with the steel strand. The steel strand can be fixed more stably and has a wind-proof swaying effect that is far superior to the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Please also read Figures 1 to 9Now, a longitudinal flexible anti-falling device provided in an embodiment of the present application is described. The longitudinal flexible anti-falling device comprises an angle steel 101, a steel strand 102, a connecting assembly and a self-locking device 105. Among them:
[0032] The steel strand 102 is arranged parallel to the angle steel 101 and spaced apart. The connection assembly includes a supporting plate 103 and a windproof fixing member 104 that are matched and connected. The supporting plate 103 is connected to the angle steel 101. The windproof fixing member 104 forms a connecting piece 141 connected to the supporting plate 103 and a wire wrapping piece 142 connected to the connecting piece 141 and wound around the steel strand 102. The self-locking device 105 forms a slideway 106 for the steel strand 102 and the wire wrapping piece 142 to pass through. The self-locking device 105 is used to form an avoidance groove 107 on the side wall of the slideway 106 for the connecting piece 141 to pass through.
[0033] According to the above structure provided in the present embodiment, in the longitudinal flexible anti-fall device provided in the present embodiment, the steel strand 102 is connected to the angle steel 101 through the anti-wind deflection fixing member 104 and the support plate 103 in sequence. Since the anti-wind deflection fixing member 104 has a wire wrapping sheet 142 wound on the steel strand 102 and the self-locking device 105 forms a slideway 106 for the steel strand 102 and the wire wrapping sheet 142 to pass through, there is no need to set a notch on the wire wrapping sheet 142 for the self-locking device 105 to pass through and it can form a stable connection with the steel strand 102. The steel strand 102 can be more stably fixed and has a wind-proof swaying effect that is far superior to the prior art.
[0034] In another embodiment of the present application, please refer to Figures 1 to 9 The wire wrapping sheet 142 forms a spiral wire entry notch 143 in the axial direction of the steel strand 102 , and the maximum spacing of the wire entry notch 143 in the circumferential direction of the steel strand 102 is smaller than the diameter of the steel strand 102 . According to the above structure provided in the present embodiment, the spiral wire entry notch 143 formed on the wire wrapping sheet 142 can make the steel strand 102 conveniently installed in the channel formed by winding the wire wrapping sheet 142; in addition, since the maximum spacing of the wire entry notch 143 in the circumferential direction of the steel strand 102 is smaller than the diameter of the steel strand 102, the steel strand 102 cannot be directly separated from the wire wrapping sheet 142 along its own radial direction, but needs to move along the spiral direction of the wire entry notch 143 under the action of external force to separate from the wire wrapping sheet 142. Therefore, in the present embodiment, the wire wrapping sheet 142 can not only facilitate the disassembly and assembly of the anti-wind deflection fixing part 104 to the steel strand 102 by setting the above-mentioned wire entry notch 143, but also can form a stable support and fixation for the steel strand 102, thereby further improving the anti-wind deflection effect of the longitudinal flexible anti-fall device provided in the present embodiment.
[0035] In another embodiment of the present application, please refer to Figures 1 to 9, the wire wrapping sheet 142 forms a plurality of wire entry notches 143 coaxially arranged and spaced apart along the axial direction of the steel strand 102. According to the above structure provided in this embodiment, the plurality of wire entry notches 143 coaxially arranged on the wire wrapping sheet 142 can not only make it more convenient to connect the wind deflection prevention fixing member 104 provided in this embodiment to the steel strand 102, but also can reduce the weight of the wind deflection prevention fixing member 104 by setting a plurality of wire entry notches 143, thereby further improving the wind deflection prevention effect of the longitudinal flexible anti-falling device provided in this embodiment.
[0036] In another embodiment of the present application, please refer to Figures 1 to 9 , the wire entry notches 143 formed on the same wire wrapping sheet 142 face the same direction. According to the above structure provided in this embodiment, the support position of the same wire wrapping sheet 142 for the steel strand 102 is located on the same side of the steel strand 102, which is conducive to forming a more stable support for the steel strand 102 and can further improve the wind deflection prevention effect of the longitudinal flexible anti-falling device provided in this embodiment.
[0037] In another embodiment of the present application, please refer to Figures 1 to 9 , multiple groups of connection components are connected to the steel strand 102 at intervals, and the wire entry notches 143 formed on the wire wrapping pieces 142 in adjacent connection components face opposite directions. According to the above structure provided in this embodiment, the wire wrapping pieces 142 in adjacent connection components can form a stable support for the opposite sides of the steel strand 102, thereby effectively reducing the wind swing amplitude of the steel strand 102 in multiple directions, which is conducive to further improving the wind deflection prevention effect of the longitudinal flexible anti-fall device provided in this embodiment.
[0038] In another embodiment of the present application, please refer to Figures 1 to 9 The cross-sectional shape formed by the winding of the wire wrap 142 is adapted to the cross-sectional shape of the steel strand 102 so that the wire wrap 142 abuts against the steel strand 102. According to the above structure provided in this embodiment, the wire wrap 142 abutting against the steel strand 102 can form a more stable support for the steel strand 102, which is conducive to further improving the wind deflection prevention effect of the longitudinal flexible anti-fall device provided in this embodiment.
[0039] In another embodiment of the present application, please refer to Figures 1 to 9 A weight-reducing notch 144 is formed on the connecting piece 141 for reducing the weight of the wind-proof fixing piece 104. According to the above structure provided in this embodiment, the weight-reducing notch 144 on the connecting piece 141 can not only reduce the overall weight of the wind-proof fixing piece 104 in this embodiment, but also eliminate the concentrated stress of the wind-proof fixing piece 104, thereby significantly improving the structural strength of the wind-proof fixing piece 104 in this embodiment and improving the wind-proof effect of the longitudinal flexible anti-fall device provided in this embodiment.
