Description

Technical Field

[0001] The invention relates to the technical field of safety protection equipment, in particular to a novel overhead roller slider for a single steel cable horizontal lifeline. Background Art

[0002] Lifeline support seats (including intermediate support seats or steering support seats) must be installed at certain intervals on the horizontal lifeline to support the wire rope so that the wire rope remains horizontal and does not sag. After the wire rope passes through the intermediate support seat, there will be a protrusion height difference at the support seat position that is higher than the wire rope.

[0003] The horizontal lifeline slider needs to move freely on the horizontally installed lifeline wire rope. All the overhead sliders currently on the market need to be manually pulled hard to pass the height difference of the protrusion when passing through the lifeline support. However, due to the limited width of the sliding channel coordinated with the lifeline slider and the wire rope, if it is pulled hard manually, there is a high probability that the front end of the slider will be pulled up, causing the lifeline slider to conflict with the bottom of the lifeline support seat and unable to pass freely and smoothly, especially for the overhead installed horizontal lifeline, because its installation height is far higher than the head height, the hand cannot touch the lifeline slider. When it gets stuck, the only way is to pull the safety rope under the slider multiple times to let the slider pass through the lifeline support seat.

[0004] However, whether the front end of the slider is pulled up or the safety rope under the slider is pulled through forcibly, it will cause irreversible damage to the slider, thereby causing the risk of falling for workers during use. At the same time, it is inconvenient for workers to grasp the slider and forced operation can easily cause the risk of misoperation. Summary of the invention

[0005] In order to ensure that the slider does not tilt up and interfere with the front of the support seat when passing through the lifeline support seat, has better passing performance, reduces the risk of construction workers falling and is convenient for high-altitude grasping, the present invention provides a new overhead roller slider for a single steel cable horizontal lifeline.

[0033] The following is combined with Figure 1-7 The present invention is described in further detail.

[0034] The embodiment of the invention discloses a novel overhead roller slider for a single steel cable horizontal lifeline.

[0035] Embodiment 1:

[0036] Reference Figure 1-Figure 3 A novel overhead roller slider 9 for a single steel cable horizontal lifeline includes a fixed rear plate 1 and a panel 2. The panel 2 is spaced apart from the fixed rear plate 1 and fixed by a connecting assembly 3. A fixed front plate 5 is movably connected between the panel 2 and the fixed rear plate 1 through a locking device 4. A passage for the lifeline steel rope to pass through is formed between the fixed rear plate 1 and the fixed front plate 5, which prevents the steel rope from escaping.

[0037] The fixed rear plate 1 and the fixed front plate 5 are integrally formed with an oblique portion 6 on one side opposite to each other, and the lifeline wire rope slides between the two opposite oblique portions 6 to ensure that the slider and the lifeline support seat do not interfere with each other below and pass smoothly through the lifeline middle support seat and the steering support seat.

[0038] In a further embodiment, the fixed front plate 5 is a movable component in the slider, and under normal use, it forms a narrow passage with the fixed rear plate 1, and the steel wire rope is fixed in the passage. The formed gap is only for the passage of the lifeline support seat, and the steel wire rope cannot be detached; a force support hole 21 is provided between the side of the fixed front plate 5 facing away from the fixed rear plate 1 and the panel 2, and a rocker 7 is fixed in the force support hole 21.

[0045] Reference Figure 1-Figure 3 In a further embodiment, the rocker 7 is cut from a steel plate and has a fall deformation indication groove 71 on the top, which can intuitively reflect when a person falls; an eccentric bending portion 72 is integrally formed at one end of the rocker 7 extending from the fixed front plate 5, and an enlarged hanging hole 73 is opened on the eccentric bending portion 72, and the position of the hanging hole is always directly below the moving slider under normal use, and no deflection occurs; the enlarged hanging hole 73 can be used to hang a variety of safety hooks.

[0046] The implementation principle of a novel overhead roller 9 slider for a single steel cable horizontal lifeline in an embodiment of the present invention is as follows:

[0047] 1. When opening the movable slider, you need to first press the button on the locking device 4 by hand, and then push the fixed front plate 5 connected to the rocker 7 upward to open the movable slider. After opening, you can hang the slider as a whole on the lifeline wire rope, or remove the slider from the lifeline wire rope.

[0048] 2. In the open state, you only need to pull the rocker 7 downward to close the movable slider, and the locking device 4 will be automatically locked. Unless manually operated, the fixed front plate 5 cannot be opened again, which can prevent the wire rope from escaping.

[0049] The triple anti-dropping method of the wire rope of a novel single-cable horizontal lifeline with an overhead roller 9 slider of the first embodiment of the present invention is as follows:

[0050] 1. The slider limits the opening that cooperates with the lifeline support seat downward, hanging on the wire rope like a hook, and will not fall off when subjected to force.

[0051] 2. The rocker 7 is fixedly connected to the fixed rear plate 1 through the connecting column 11, and the force is increased through the reinforcing rib 12 to prevent the moving slider from flipping.

[0052] 3. Even if the movable slider is turned over, the steel wire rope can be confined in the narrow passage of the slider to prevent it from falling off due to the restricted opening formed between the fixed rear plate 1 and the fixed front plate 5.

[0053] The principle of preventing misoperation of a new type of overhead roller 9 slider for a single steel cable horizontal lifeline according to an embodiment of the present invention is as follows:

[0054] 1. When the lifeline moving slider is in use, a safety hook, a safety rope or a fall arrester must be hung below the main hanging point of the rocker 7. The moving slider of this design can only be opened when the rocker 7 is pushed upward. It must be in a closed state when in use, and there is a locking device 4 to limit the position to avoid the risk of falling due to misoperation.

[0055] 2. The movable slider can only be opened after two steps, provided that the worker must stand in a safe area, without any force below, and must press the button by hand and push the fixed front plate 5 or the rocker 7 upwards to open the movable slider, which can completely prevent the lifeline wire rope from coming out due to worker's misoperation.

[0056] 3. To move the slider, just open your hand and hang it on the wire rope, then pull it down to lock it, which is convenient and quick.

[0057] 4. This design has a compact structure, clear functions of each part, ergonomic design, easy to hold, and extremely simple to open and lock.

[0058] Embodiment 2:

[0059] Reference Figure 4 and Figure 7 The difference between this embodiment and the first embodiment is that the rocker 7 is movably connected to the fixed front plate 5 through the connecting shaft 13, the rocker 7 is rotatably arranged in the force-bearing support hole 21 with the connecting shaft 13 as the axis, a limiting groove 53 for limiting the movement range of the rocker 7 is opened on the fixed front plate 5, and a sliding limit rod 8 cooperating with the limiting groove 53 is provided on the rocker 7 to ensure that the rocker 7 will not flip or tilt when subjected to force. In this embodiment, the sliding limit rod 8 can be a stainless steel bushing to ensure free movement under a firm condition;

[0060] In a further embodiment, the rocker 7 is installed between the panel 2 and the fixed front plate 5, and a movable groove 10 is opened on the panel 2. The rocker 7 can swing left and right in the movable groove 10 through the sliding limit rod 8 and the swing range is limited by the movable groove 10.

[0061] The triple anti-dropping method of the wire rope of a novel single-cable horizontal lifeline with an overhead roller 9 slider of the second embodiment of the present invention is as follows:

[0062] 1. The slider limits the opening that cooperates with the lifeline support seat downward, hanging on the wire rope like a hook, and will not fall off when subjected to force.

[0063] 2. The rocker 7 is provided with a sliding limit rod 8, which moves in the limit groove of the fixed front plate 5, and forms a fulcrum when a fall occurs to prevent the moving slider from flipping.

[0064] 3. Even if the movable slider is turned over, the steel wire rope can be confined in the narrow passage of the slider to prevent it from falling off due to the restricted opening formed between the fixed rear plate 1 and the fixed front plate 5.

[0065] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
