Specific embodiments

[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0027] Reference Figures 1 to 3 , the utility model provides an embodiment: a kind of applicable to special equipment safety belt's suspension device when the hanging point of no high, including encircling fixed rod one 1, operating personnel first places encircling fixed rod one 1 in the part that outdoor circuit breaker needs to be fixed, encircling fixed rod one 1 as the basis load-bearing component of entire device, inner cavity 2 being opened in its interior provides space for the movement of subsequent components, holds rotating handle 8 on rotating rod 3 and rotates, rotating rod 3 penetrates encircling fixed rod one 1, its outside rotationally connected in the inside of encircling fixed rod one 1, and the upper and lower ends of rotating rod 3 are rotationally connected in the upper and lower sides in the inside of encircling fixed rod one 1, this design guarantees the stability and flexibility when rotating rod 3 rotates, when rotating rod 3 rotates, rotating disc 4 fixedly connected with it is synchronously rotated in the inner cavity 2 of encircling fixed rod one 1, rotating disc 4 is also rotationally connected in the upper and lower sides in the inside of encircling fixed rod one 1 by upper and lower sides, to ensure that rotating process is stable, and deviation does not occur.

[0028] Reference Figures 1 to 3Since the arc-shaped rods 5 are rotationally connected to the left and right sides of the outer part of the rotating disc 4, the rotation of the rotating disc 4 will make the arc-shaped rods 5 rotate around the connecting points with the rotating disc 4. The arc-shaped rods 5 serve as force transmission and conversion components, and their unique arc-shaped design can effectively change the direction and action distance of the force during rotation. As the arc-shaped rods 5 rotate, the connecting plates 6 connected to the other ends of the arc-shaped rods 5 also move. The outer part of the connecting plates 6 is slidingly connected to the inner left and right sides of the embracing fixed rod one 1. This sliding connection mode not only ensures that the connecting plates 6 can move freely within a certain range, but also limits the movement direction, ensuring that the connecting plates 6 can only slide along the left and right directions of the inner part of the embracing fixed rod one 1. In turn, the connecting plates 6 push the embracing fixed rod two 7 to move closer to or away from the circuit breaker, and the embracing fixed rod two 7 and the embracing fixed rod one 1 together form an embracing structure for enclosing the circuit breaker.

[0029] When the embracing fixed rod two 7 and the embracing fixed rod one 1 gradually embrace the circuit breaker, the tightness of the embrace can be further adjusted by continuously rotating the rotating handle 8. In this process, the embracing anti-slip rubber one 14 fixedly connected to the top of the embracing fixed rod one 1 and the embracing anti-slip rubber two 15 fixedly connected to the side near the embracing fixed rod two 7 play a key role. These two anti-slip rubber materials have good friction and flexibility, and can closely fit the shape of the surface of the circuit breaker during the embracing process. Even if the surface of the circuit breaker has a certain curvature, concave-convex or unevenness, it can also fill the gap and increase the contact area through its own deformation, thereby providing stronger friction to prevent the suspension device from sliding on the circuit breaker.

[0030] Referring to Figures 1 to 3 When the appropriate tightness of the embrace is adjusted, the bolts 9 on the left and right sides of the inner part of the embracing fixed rod one 1 begin to play a role. The bolts 9 are connected with the embracing fixed rod one 1 through threads. When the bolts 9 are tightened, the bolts 9 gradually move upwards, and their top parts come into contact with the bottom of the connecting plates 6 and apply pressure. As the pressure gradually increases, the friction on the connecting plates 6 also increases, thereby limiting the movement of the connecting plates 6 and fixing the position of the embracing fixed rod two 7. In this way, the entire embracing structure can be stably fixed on the circuit breaker and will not loosen due to external forces during the operation process, such as personnel shaking and wind action, thereby realizing the tight embrace of circuit breakers of different sizes and shapes.

[0031] The bottom of the ring type fixing rod one 1 is fixedly connected with two fixing frames 10 on the front and back sides, the outer part of the two fixing frames 10 is sleeved with a lasso 11, the bottom of the lasso 11 is fixedly connected with a safety belt 12, the outer part of the safety belt 12 is sleeved with a safety belt hanging ring 13, and this series of structures form a complete safety protection system, the fixing frame 10 provides a fixed connecting point for the lasso 11, the lasso 11 has certain flexibility and strength, can be adapted to the activities of the operating personnel while ensuring firm connection, the operating personnel hang the safety belt hanging ring 13 in a suitable position, are connected with the fixing frame 10 through the lasso 11, and can safely operate on the outdoor circuit breaker in the case that there is no high hanging point by means of the suspension device, thereby providing a reliable safety hanging point for the operating personnel.

[0032] Working principle: the operating personnel place the ring type fixing rod one 1 at the position to be fixed of the outdoor circuit breaker, hold the rotating handle 8 on the rotating rod 3 and rotate, when the rotating rod 3 rotates, the rotating disc 4 fixedly connected with the rotating rod 3 rotates in the inner cavity 2 of the ring type fixing rod one 1, since the outer part of the rotating disc 4 is rotatably connected with the arc-shaped rods 5 on the left and right sides, the rotation of the rotating disc 4 drives the arc-shaped rods 5 to rotate around the connecting points with the rotating disc 4, with the rotation of the arc-shaped rods 5, the connecting plates 6 connected with the other ends of the arc-shaped rods 5 also move, thereby driving the ring type fixing rod two 7 to move towards or away from the circuit breaker, when the ring type fixing rod two 7 and the ring type fixing rod one 1 gradually embrace the circuit breaker, the rotating handle 8 is continuously rotated to adjust the tightness of the embrace until the ring type anti-skid rubber one 14 at the top of the ring type fixing rod one 1 and the ring type anti-skid rubber two 15 on the side close to the ring type fixing rod two 7 are tightly attached to the surface of the circuit breaker.

[0033] The bolts 9 on the left and right sides in the ring type fixing rod one 1 play a role at this time, the bolts 9 are tightened to make the top thereof contact the bottom of the connecting plate 6, the movement of the connecting plate 6 is limited, thereby fixing the position of the ring type fixing rod two 7, ensuring that the embracing structure is stable and will not be loosened due to external force in the operation process, thereby realizing the close embrace of the circuit breaker of different sizes and shapes and providing a reliable safety hanging point for the operating personnel.

[0034] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for some technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
