[0030] Referring to the accompanying drawings to illustrate this embodiment, a lifeline auxiliary wheel includes:

[0031] The wire rope anti - detachment positioning piece 4 has wing pieces 6 provided at both ends. Each of the wing pieces 6 is used to be inserted into the internal or external corner of a fixed position. Through the setting of the wing pieces 6, in the internal or external corner of a construction or aerial work environment, by inserting the wing pieces 6 into the internal or external corner, the auxiliary wheel can be well - assisted and fixed. Thus, through the wing pieces 6, this application can adapt to the working environments of internal and external corners, helping this device to have good adaptability and safety, improving the on - site work efficiency. There is no need to make a temporary lap to adapt to the working environment of internal or external corners, saving unnecessary steps. At the same time, it can avoid the problem of poor safety caused by the instability of the temporary lap. Specifically, the wing pieces 6 are set in the form of thin sheets. The height can be equal to that of the wire rope anti - detachment positioning piece 4 or lower than it, which is convenient for better finding the insertion position and improving stability and adaptability.

[0032] The wire post 8 has one end rotatably connected to the middle position of the wire rope anti - detachment positioning piece 4 and is located on the same side end face as all the wing pieces 6. Two flywheels 10 are symmetrically arranged in the middle of the wire post 8. On one side of each flywheel 10 away from the middle position of the wire post 8, there is a fixing component connected to the wire post 8. The wire post 8 is used to provide rotational support for the flywheels 10. For the flywheels 10, they are fixed to the wire post 8 by welding. When the fixing component falls off, it can still provide reliable support for the user, preventing the phenomenon of the flywheels 10 falling off. Specifically, the wire post 8 is connected to the wire rope anti - detachment positioning piece 4 in a form of movable socketing, and the rotation range is 0 - 360°. It should be noted that both the rear bolt 7 and the front bolt 9 are connected and fixed to the wire post 8 by welding. So that on the premise that the wire post 8 can rotate relative to the wire rope anti - detachment positioning piece 4, the auxiliary wheel will not fall due to the detachment of the rear bolt 7 and the front bolt 9. The auxiliary wheel can be flexibly applied to various terrains and environments, being more stable and not easy to fall off.

[0033] In this embodiment, the fixing component is a bolt. Bolts are convenient to obtain materials, low in price, high in safety and easy to connect. Just set the corresponding threads on the wire post 8 to match it. For the two fixings, for the sake of distinction, the one closer to the wire rope anti - detachment positioning piece 4 is set as the rear bolt 7, and the one farther away is set as the front bolt 9. Commercially available bolts can be used and selected according to the diameter of the wire post 8.

[0034] In this embodiment, the wing pieces 6 are arranged perpendicular to the wire rope anti - detachment positioning piece 4. The setting method of the wing pieces 6 being perpendicular to the wire rope anti - detachment positioning piece 4 can provide a good mechanical structure and improve the stability of supporting and fixing the wire rope anti - detachment positioning piece 4 during support.

[0035] In this embodiment, a wing angle 5 is formed between the wing piece 6 and the wire rope anti - detachment positioning piece 4, and the wing angle 5 is arranged in the form of a rounded - corner processing. The setting of the wing angle 5 can improve the structural strength, enhance the anti - deformation ability of the wing piece 6 and appropriately filter vibrations during use, etc., thereby improving the stability and reliability of the device during use and enhancing the user experience. For the thickness, the wire rope anti - detachment positioning piece 4, the wing angle 5, and the wing piece 6 can be set to have the same thickness.

[0036] In this embodiment, the center of the wing angle 5 is located on the side away from between the two wing pieces 6. This can shorten the distance between the two wing pieces 6 and improve stability.

[0037] In this embodiment, the wing angle 5, all the wing pieces 6, and the wire rope anti - detachment positioning piece 4 are integrally die - cast. The setting of the wing angle 5 can improve the toughness of the wing piece 6, filter the vibrations generated during use during use, thereby enhancing the user's feeling during use and reducing the fear psychology. The integrally die - cast method can improve the convenience of production. Through this kind of structure, this auxiliary wheel can have a good use experience and fixing effect in both straight sections and internal and external corners, improving safety.

[0038] In this embodiment, the flywheel 10 is in the shape of a petal. There are multiple evenly - distributed blades circumferentially arranged on the connecting piece in the middle position and are welded to the wire post 8 through the connecting piece.

[0039] In this embodiment, a fastening assembly for fixing on a rod is fixedly connected to the side of the wire rope anti - detachment positioning piece 4 away from the wire post 8.

[0040] In this embodiment, the fastening assembly includes a mounting seat 1 fixedly connected to the wire rope anti - detachment positioning piece 4 and a hoop 2 whose one end is rotatably connected to the mounting seat 1. The free end of the hoop 2 is connected to the mounting seat 1 through a locking assembly, and the space for locking the rod is enclosed by the hoop 2 and the mounting seat 1. The hoop 2 is specifically in the form of a semi - ring, and a semi - ring matching the hoop 2 is provided on the mounting seat 1, so as to enclose a complete ring for use and can lock railings, etc.

[0041] In this embodiment, the locking assembly is a locking bolt 3. Place the corresponding rod, such as a railing, between the mounting seat 1 and the hoop 2. The placement process can be achieved by rotating the hoop 2. After placing it in place, fix the free ends of the mounting seat 1 and the hoop 2 through the locking bolt 3 to complete the locking of the device. Through the cooperation of the locking assembly and the wing piece 6, this auxiliary wheel can be well fixed at the positions of internal and external corners, improving the practicability of this auxiliary wheel.

[0042] When in use: first open the hoop 2, put the hoop 2 on the external steel column, use the locking bolt 3 to lock and fix it, and then place the two sets of wing pieces 6 at the wire rope anti-slip positioning piece 4 above the lifeline wire rope, and the wire column 8 is under the wire rope. When in use, the safety buckle passes through the lifeline wire rope, and when it passes through the position of the wire column 8, it will drive the flywheel 10 to rotate a certain angle. There is no need to unlock the safety buckle while turning it. The auxiliary wheel as a whole can not only be used in straight sections, but also can be assembled at the inner and outer corners of mountains, stone bodies, and buildings through the wing angles 5. The fixing range is not limited. The lifeline auxiliary wheel is fixed with front and rear double bolts, and is installed at both ends of the flywheel 10 by welding, so that the wire column 8 can rotate relative to the wire rope anti-slip positioning piece 4 without causing the auxiliary wheel to fall off due to the falling off of the rear bolt 7 and the front bolt 9. It can be fixed or opened by the locking bolt 3, and can be quickly and conveniently installed on facilities such as railings, which is convenient for rapid disassembly, maintenance and updating.
