[0003] For the traditional anti - falling rope fixing device, when fixing the opening fixing ring, it is necessary to drill holes and fix screws on the electric power tower, which has a certain impact on the strength of the tower. In addition, since the anti - falling rope tension needs to be borne at the corner, there is no gap between the anti - falling ropes and between the opening fixing rings. And due to the action of the anti - falling rope tension, when the anti - falling device passes through, the climber needs to use greater strength to overcome the tension and pass through the opening fixing ring by hard friction, with a greater intensity, and performing high - intensity actions in the air has safety risks.

[0004] Therefore, the utility model provides an anti - falling rope fixing device for a multi - axis rotating anti - falling device to pass through to meet the requirements. Content of the Utility Model

[0023] The following is a detailed description of a fall prevention rope fixing device for a multi-axis rotating fall arrester provided by the utility model in conjunction with the accompanying drawings and specific embodiments; at the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some known technologies, those skilled in the art may also adopt other alternative methods.

[0024] like Figures 1 to 4 As shown, the embodiment of the utility model provides an anti-fall rope fixing device for a multi-axis rotating anti-fall device, comprising a main frame 12, the interior of the main frame 12 is fixedly connected with a rotating main shaft 6, the outer side of the rotating main shaft 6 is rotatably connected with a rotating main frame 4, the outer sides of both ends of the contact surface between the rotating main shaft 6 and the main frame 12 are fixedly connected with main shaft fixing components 14, and the opposite sides of the two main shaft fixing components 14 are in close contact with the two sides of the main frame 12 respectively; a mounting mechanism, the mounting mechanism is used for fixing the device, the mounting mechanism is connected to the main frame 12, and the mounting mechanism is fixedly connected On the side of the main frame 12 away from the rotating main axis 6, the installation mechanism includes a straight fixed component 11 fixedly connected to the main frame 12, and both ends of the straight fixed component 11 away from the main frame 12 are fixedly connected with bending spring clips 10, and the two bending spring clips 10 are internally clamped with the same bending fixed component 9. The straight fixed component 11 and the bending fixed component 9 are both right-angle structures, and the bending spring clip 10 is an elastic structure. The bending fixed component 9 is located on the side of the straight fixed component 11 close to the main frame 12, and the two ends of the bending fixed component 9 pass through the two bending spring clips 10 respectively and are threaded with bolts.

[0025] By hooking the edge of the power tower angle iron through the bending spring clip 10 in the installation mechanism and locking the screws on both sides of the bending and fixing component 9, combined with the ingenious design of the straight fixing component 11, the power tower angle iron can be firmly fixed. The special design of the bending spring clip 10 provides elastic expansion, which can effectively prevent the bolts from loosening and ensure a firm connection, and it is supported by a double installation mechanism.

[0026] like Figures 1 to 4As shown, a snap ring 5 is fixedly connected to one end of the rotating main shaft 6 away from the main shaft fixing assembly 14. The snap ring 5 is in close contact with the side of the rotating main frame 4 away from the main frame 12. A main shaft bearing assembly 13 is fixedly connected to the rotating main shaft 6, and it is in close contact with one end of the rotating main frame 4 close to the main frame 12 inside. The rotating main frame 4 includes centering rotating shafts 2 fixedly connected to the inner periphery all around. Flange bearings 3 are fixedly connected to both sides of the centering rotating shaft 2. The centering rotating shaft 2 is fixed inside the rotating main frame 4 through the flange bearings 3. Blocking rings 7 are fixedly connected to the outer sides of both ends of the centering rotating shaft 2. Open blocking rings 1 are fixedly connected to the top and bottom of the main frame 12. The rotating main frame 4 is located inside the two open blocking rings 1. A number of spacer components 8 are fixedly connected inside the rotating main frame 4, and they are annularly distributed inside the rotating main frame 4.

[0027] The centering rotating shaft 2 and the blocking ring 7 together form a rotating centering shaft with a block. The rotating main frame 4 restricts the rotating centering shaft with a block through the spacer components 8 and the flange bearings 3, and contacts the rotating main shaft 6 through the main shaft bearing assembly 13 to form a main rotating mechanism.

[0028] The anti-falling rope passes through the centering rotating shaft 2, which can effectively restrain the anti-falling rope at a specific position. The tension of the anti-falling rope acts on the rotating centering shaft with a block. When the anti-falling device passes through, the anti-falling device first contacts the rotating centering shaft with a block. At this time, the main rotating mechanism rotates under the action of gravity or other forces through the rotating main shaft 6 and the main shaft bearing assembly 13, so that the anti-falling device is exactly between the two rotating centering shafts with a block, thereby slowing down the tension of the anti-falling rope. The main rotating mechanism continues to rotate under the action of gravity or other forces, and the anti-falling device crosses the fixing device, realizing the rolling through of the anti-falling device across, avoiding the labor intensity and safety risks of employees working in the air. For safety reasons, the anti-falling rope passes through the open blocking ring 1, which restrains the anti-falling rope again, giving the whole device a secondary safety insurance.

[0029] The working principle provided by the present utility model: The bending spring clip 10 in the installation mechanism hooks the edge of the angle iron of the power transmission tower, and at the same time tightens the screws on both sides of the locking and fixing assembly 9 to fix the device on the outside of the angle iron of the power transmission tower. The anti-falling rope passes through the centering rotating shaft 2, which can effectively restrain the anti-falling rope at a specific position. The tension of the anti-falling rope acts on the rotating centering shaft with a block. When the anti-falling device passes through, the anti-falling device first contacts the rotating centering shaft with a block. At this time, the main rotating mechanism rotates under the action of gravity or other forces through the rotating main shaft 6 and the main shaft bearing assembly 13, so that the anti-falling device is exactly between the two rotating centering shafts with a block, thereby slowing down the tension of the anti-falling rope. The main rotating mechanism continues to rotate under the action of gravity or other forces, and the anti-falling device crosses the fixing device, realizing the rolling through of the anti-falling device across.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can also fully understand the present utility model without the description of these details.

[0031] The above are only the preferred embodiments of the present utility model.
