Description

Technical Field

[0001] The present application relates to the technical field of power engineering installation, and in particular to an auxiliary structure for adding a circuit breaker. Background Art

[0002] Pole-mounted circuit breakers are outdoor circuit breakers installed on electric poles. With the advancement of the national power grid transformation project, a large number of pole-mounted circuit breakers need to be installed.

[0003] The pole is usually provided with a mounting frame for stably placing the circuit breaker, and the mounting frame is usually located at a position higher than the ground. The existing method of installing the circuit breaker on the mounting frame is usually to use a crane for hoisting, and the circuit breaker is lifted by the crane and placed on a fixed point from top to bottom.

[0004] However, when the circuit breaker is hoisted by a manually operated crane, the sling will inevitably shake, which may cause the circuit breaker to fall to a fixed point inaccurately, resulting in the subsequent installation of the circuit breaker not being firm and stable enough, which may affect the normal use of the circuit breaker and even pose a safety hazard of the circuit breaker falling. Utility Model Content

[0005] In order to improve the problem of inaccurate installation position of a circuit breaker and enhance the stability of the circuit breaker, the present application provides an auxiliary installation structure for a circuit breaker.

[0006] The auxiliary structure for adding a circuit breaker provided in the present application adopts the following technical solution:

[0007] An auxiliary structure for installing a circuit breaker comprises an electric pole, a mounting frame and an inclined support frame, wherein the mounting frame is vertically arranged on the upper part of the electric pole for installing the circuit breaker, the inclined support frame is located below the mounting frame and is fixedly connected to the electric pole and the mounting frame, a limit frame for guiding the circuit breaker to fall is arranged above the mounting frame, and the limit frame is fixedly connected to the mounting frame and the electric pole.

[0008] By adopting the above technical solution, the mounting frame is vertically set on the pole, and the diagonal support frame is fixedly connected between the pole and the mounting frame. The diagonal support frame increases the stability of the overall structure, making the mounting frame less susceptible to external forces and causing deviation or shaking, thereby improving the stability of the circuit breaker after installation. The setting of the limit frame can ensure that the circuit breaker is properly guided and controlled during the falling process, preventing it from suddenly falling or causing other dangers due to unexpected reasons. It protects the safety of the staff, reduces the risk of equipment damage, and effectively improves the installation accuracy and stability of the circuit breaker.

[0009] Furthermore, the limit frame is symmetrically arranged on both sides of the mounting frame, and the limit frame includes a transverse rod and a longitudinal rod. The transverse rod and the longitudinal rod are arranged perpendicular to each other and the ends are fixedly connected. One end of the transverse rod away from the longitudinal rod is fixedly connected to the pole, and one end of the longitudinal rod away from the transverse rod is fixedly connected to the mounting frame.

[0010] By adopting the above technical solution, the symmetrically arranged limit frames can provide more balanced and stable support for the circuit breaker on both sides of the mounting frame, which helps to prevent the circuit breaker from tilting or shifting during installation and improves installation accuracy. The limit frame is composed of transverse rods and longitudinal rods that are perpendicularly arranged and fixedly connected to each other to form a stable frame, ensuring that the circuit breaker falls along a predetermined trajectory, avoiding accidental falling or shaking, thereby improving work safety.

[0011] Furthermore, the limiting frame also includes an inclined support rod, and both ends of the support rod are respectively fixedly connected to a side of the mounting frame close to the pole and at a corner position of the transverse rod and the longitudinal rod.

[0012] By adopting the above technical solution, the support rod is tilted on the mounting frame and at the corner position of the limit frame to form a triangular support structure with a stable mechanical structure, which can enhance the stability of the mounting structure and prevent the circuit breaker from shaking or tilting during installation or operation. The support rod can disperse and bear the impact force when the circuit breaker falls, avoid direct impact between the circuit breaker and the mounting frame and the pole, and help reduce the risk of damage to the circuit breaker.

[0013] Furthermore, it also includes a pre-installed frame for assisting the installation of the circuit breaker, the pre-installed frame is rotatably connected to the side of the mounting frame away from the pole, the side of the pre-installed frame away from the mounting frame is provided with a pull ring, the pole is provided with a fixed pulley, the fixed pulley is located above the limit frame, the pull ring is detachably connected with a guide rope for flipping the pre-installed frame, the guide rope passes over the fixed pulley and extends to the ground;

[0014] The mounting frame is provided with a placement slot for accommodating the pre-installed frame. When the pre-installed frame is flipped into the placement slot, the heights of the pre-installed frame and the mounting frame are flush with each other.

[0015] By adopting the above technical solution, after the circuit breaker is installed on the pre-installed frame, the circuit breaker is directly installed on the mounting frame on the pole by flipping the pre-installed frame. This method avoids the complicated installation operation of repeatedly aligning the crane. The staff only needs to operate the guide rope on the ground to complete the flipping of the pre-installed frame. The guide rope and fixed pulley make the process of flipping the pre-installed frame smoother and more controllable, simplifying the installation process. The flipped pre-installed frame is flush with the height of the mounting frame, so that the circuit breaker can remain horizontal during the installation process, avoiding the problem of inaccurate installation position of the circuit breaker.

[0016] Furthermore, the pre-installed frame includes a connecting rod, a supporting rod and a lifting assembly for lifting the circuit breaker, the number of the connecting rods is at least two and both are rotatably connected to the mounting frame, the supporting rod is vertically fixedly connected between the two connecting rods for supporting the circuit breaker, and the lifting assembly is arranged between the two connecting rods.

[0017] By adopting the above technical solution, the pre-installation frame is rotatably connected to the installation frame through at least two connecting rods, which improves the stability of the structure and ensures the stability of the pre-installation frame during the flipping process. The support rod is vertically fixedly connected between the two connecting rods to provide a placement platform for the circuit breaker. The setting of the lifting assembly enables the staff to lift the circuit breaker to the pre-installation frame on the ground, thereby simplifying the difficulty of high-altitude operations and improving installation efficiency.

[0018] Furthermore, the lifting assembly includes a reversing wheel, a sling and a pre-installed plate for pre-fixing the circuit breaker, the number of the sling and the reversing wheel is at least two, the two reversing wheels are respectively arranged on both sides of the supporting rod, the ends of the two slings are respectively connected to the two sides of the pre-installed plate, and the ends of the two slings away from the pre-installed plate respectively bypass the two reversing wheels and extend to the ground.

[0019] By adopting the above technical solution, the arrangement of the reversing wheel and the sling can lift the circuit breaker, and the pre-installed plate pre-fixes the circuit breaker before lifting to ensure that it will not slide or fall off during the lifting process, thereby improving the safety of the installation process. The staff only needs to fix the circuit breaker on the pre-installed plate on the ground and operate the sling to change the direction of the sling through the reversing wheel, so as to lift the pre-installed plate and the circuit breaker to abut against the supporting rod of the pre-installed frame. The number of slings and reversing wheels is at least two, which are respectively arranged on both sides of the supporting rod, ensuring the stability of the lifting process. Multiple slings and reversing wheels can evenly share the lifting force to prevent instability caused by excessive force on a single point.

[0020] Furthermore, the reversing wheel includes a reversing wheel body and a rotating shaft, the rotating shaft is fixedly connected between the two connecting rods and is perpendicular to the connecting rods, the reversing wheel body is rotatably connected to the middle position of the rotating shaft, and limit members are symmetrically arranged on both sides of the reversing wheel body to prevent the reversing wheel body from displacement.

[0021] By adopting the above technical solution, the rotating shaft is fixedly connected between the two connecting rods and is perpendicular to the connecting rods, which ensures the stable installation of the reversing wheel and can withstand the tension from the sling. The reversing wheel body is rotatably connected to the middle position of the rotating shaft, so that the sling can change direction smoothly when passing around the reversing wheel. The limiters are symmetrically arranged on both sides of the reversing wheel body, which can effectively prevent the reversing wheel body from being displaced during the rotation process, ensure the stability and safety of the lifting assembly, and reduce the risk caused by the displacement of the reversing wheel body.

[0022] Furthermore, the pre-installed plate is provided with a mounting hole for installing the circuit breaker, and a connecting piece for connecting with the circuit breaker is penetrated in the mounting hole;

[0023] When the pre-installed plate is lifted to abut against the supporting rod, two sides of the pre-installed plate are clamped and fixed between the two connecting rods.

[0024] By adopting the above technical solution, by opening a mounting hole on the pre-installed plate that matches the size of the circuit breaker, the accurate position of the circuit breaker on the pre-installed plate can be ensured, which helps to reduce errors during the installation process. The connector inserted in the mounting hole is connected to the circuit breaker, so that the circuit breaker can be firmly installed on the pre-installed plate, improving the stability of the circuit breaker during the lifting process and preventing it from sliding or falling. When the pre-installed plate is lifted to abut against the supporting rod, the two sides of the pre-installed plate are clamped and fixed between the two connecting rods to prevent the circuit breaker from falling during the flipping of the pre-installed frame, thereby improving the installation stability.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The mounting frame is vertically arranged on the upper part of the pole, and the diagonal support frame is fixedly connected between the pole and the mounting frame, providing a stable installation foundation for the circuit breaker. The setting of the limit frame can guide the falling trajectory of the circuit breaker, prevent the circuit breaker from shaking or even falling, and enhance the safety of the installation structure;

[0027] 2. The installation holes and connectors on the pre-installed plate allow the circuit breaker to be pre-installed on the ground. After the circuit breaker is fixedly connected to the pre-installed plate, it is lifted to the lower position of the pre-installed frame through the guide rope and fixed pulley. While improving the installation efficiency, the lifting assembly and reversing wheel make the lifting process of the circuit breaker more stable, reducing the risk of equipment damage caused by shaking or collision;

[0028] 3. The rotational connection between the pre-installed frame and the mounting frame allows the pre-installed frame to be flipped into the placement slot of the mounting frame. The limit frame has a limiting effect on the pre-installed frame and the circuit breaker, guiding the flipping of the pre-installed frame and the falling process of the circuit breaker to prevent the pre-installed frame and the circuit breaker from lateral shaking or even displacement, improving the problem of inaccurate installation position of the circuit breaker and improving the stability of the circuit breaker.
