[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference below Figures 1 to 5 The circuit breaker assembly turning tool according to the embodiment of the utility model is described.

[0035] refer to Figures 1 to 5 As shown, the circuit breaker assembly flip tool according to the embodiment of the utility model includes a base 100, a flip part 200 and a limit assembly 300.

[0036] The base 100 can be fixed to the ground or a workbench by fasteners such as expansion bolts.

[0037] The flip part 200 is connected to the base 100 flippably around a horizontal axis. The flip part 200 is used to fix the crank box 400. The flip part 200 can be flipped to a first state and a second state. When the flip part 200 is in the first state, the connecting hole of the crank box 400 on the flip part 200 for connecting the tank body 500 penetrates vertically, and the connecting hole of the tank body 500 generally penetrates along the length direction of the tank body 500. Then, when the tank body 500 is assembled by a crane, the crane can be connected to the top of the tank body 500. The tank body 500 can be roughly in a vertical state under the action of its own gravity. The connecting holes of the tank body 500 penetrate vertically, which makes it easier to align the connecting holes of the tank body 500 with the connecting holes of the crank box 400, thereby making assembly more convenient. After the circuit breaker is assembled, the tank body 500 extends vertically. When the circuit breaker needs to be flipped, a crane can be connected to the top of the tank body 500, and then the crane is operated to flip the circuit breaker and the flip part 200 together, so that the flip part 200 is in the second state. In this state, the connection hole of the crank box 400 for connecting the tank body 500 passes through horizontally, and accordingly, the tank body 500 also extends horizontally, so as to facilitate the installation of the circuit breaker as a whole on the mounting frame.

[0038] The limiting assembly 300 is arranged between the base 100 and the flip part 200. When the flip part 200 is in the first state, the limiting assembly 300 can limit the flip part 200 to keep the flip part 200 in the first state, thereby preventing the flip part 200 from flipping at will and affecting the assembly of the circuit breaker. After the assembly is completed, the limiting assembly 300 releases the limit on the flip part 200, so that the flip part 200 can be easily flipped from the first state to the second state.

[0039] The circuit breaker assembly flipping tool according to the embodiment of the utility model not only has a simple structure and occupies a small area, but also is more convenient to operate when the circuit breaker needs to be flipped, saving time and effort. In addition, there is no need for multiple people to operate two cranes, but only one person to operate one crane, which requires fewer people and lower labor costs. In addition, during the flipping process, since the crank box 400 is fixed to the flipping part 200, there will be no shaking, thereby improving the assembly quality, improving safety, and reducing the space required for flipping.

[0040] In some embodiments of the present invention, Figures 1 to 3As shown, the limiting assembly 300 includes a first limiting rod 301, a second limiting rod 302 and a fixing pin 303. The first limiting rod 301 is arranged on the base 100, and a first limiting hole is arranged at the end of the first limiting rod 301. The second limiting rod 302 is arranged on the flip part 200, and a second limiting hole is arranged at the end of the second limiting rod 302. When the flip part 200 is in the first state, the first limiting hole and the second limiting hole are aligned, and the fixing pin 303 is inserted into the first limiting hole and the second limiting hole. When the tank body 500 needs to be assembled, the flip part 200 is flipped to the first state, in which the first limiting hole and the second limiting hole are aligned, and finally the fixing pin 303 is inserted into the first limiting hole and the second limiting hole, so that the flip part 200 can be limited, thereby limiting the flip part 200 from rotating at will. When the flip part 200 needs to be flipped, the fixing pin 303 is pulled out to separate the first limiting rod 301 and the second limiting rod 302, so that the limiting of the flip part 200 can be released, so that the flip part 200 can be flipped from the first state to the second state. The structure is simple, the operation is convenient, and the limiting effect is good.

[0041] It is understandable that the first limiting rod 301 can be welded to the base 100 or formed integrally with the base 100, and the second limiting rod 302 can be welded to the flip part 200 or formed integrally with the flip part 200. The axis of the fixing pin 303 does not coincide with the rotation axis of the flip part 200 to avoid failure to provide a limiting effect.

[0042] It should be noted that the limiting assembly 300 may also be other structures, for example, it may be a support plate arranged on the base 100. When the flip part 200 flips to the first state, the flip part 200 abuts against the top of the support plate and is connected to the support plate through fasteners.

[0043] In some embodiments of the present invention, Figures 1 to 3 As shown, the first limiting rod 301 extends vertically, and when the flip part 200 is in the first state, the second limiting rod 302 extends vertically. With such a configuration, when the flip part 200 flips to the first state, the first limiting rod 301 and the second limiting rod 302 both extend vertically, and after the fixing pin 303 is inserted, the first limiting rod 301 and the second limiting rod 302 have a better supporting effect on the flip part 200, thereby providing a more stable support for the circuit breaker.

[0044] In some embodiments of the present invention, Figures 1 to 3As shown, the flip part 200 includes a rotating part 201 and a mounting plate 202. The rotating part 201 is flippably connected to the base 100 around a horizontal axis. The mounting plate 202 is provided on the rotating part 201. The mounting plate 202 is used to install the crank box 400. When the flip part 200 is in the first state, the mounting plate 202 is located at the top of the rotating part 201 and is arranged horizontally to support the crank box 400. In this embodiment, the mounting plate 202 is provided. When the flip part 200 is in the first state, the mounting plate 202 is located at the top of the rotating part 201 and is arranged horizontally, thereby supporting the circuit breaker more stably and having a better supporting effect.

[0045] In some embodiments of the present invention, Figure 1 As shown, the mounting plate 202 is provided with a plurality of mounting holes 203, and the mounting holes 203 are used to connect with the crank box 400 through fasteners. For example, the mounting plate 202 may be provided with four mounting holes 203, and then the crank box 400 may be mounted on the mounting plate 202 through fasteners, which not only has a simple structure, but also makes it more convenient to install the crank box 400, and also has a better fixing effect on the crank box 400.

[0046] It should be noted that the crank box 400 may also be fixed to the mounting plate 202 in other ways, such as being fixed to the mounting portion 102 by a clamp.

[0047] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, a reinforcing rib 204 is provided between the mounting plate 202 and the rotating part 201. For example, the reinforcing rib 204 may be two and located on opposite sides of the rotating part 201, and the reinforcing rib 204 may be an obliquely pulled reinforcing rib. In this embodiment, the reinforcing rib 204 is provided to improve the structural strength of the flip part 200, so that the flip part 200 can withstand a heavier circuit breaker, and the flip part 200 is less likely to be damaged and has a longer service life.

[0048] In some embodiments of the present invention, a buffer plate (not shown) is laid on the surface of the mounting plate 202. When the flip part 200 is in the first state, the buffer plate is located above the mounting plate 202. The buffer plate can be a glass plastic plate, that is, an organic glass plate. In addition, it can also be made of other materials, such as rubber, which will not be described here. In this embodiment, the buffer plate is provided to reduce the rigid impact force between the circuit breaker and the flip part 200, thereby preventing the crank box 400 and the flip part 200 from being damaged.

[0049] In some embodiments of the present invention, Figures 1 to 3As shown, the base 100 includes a bottom plate 101 and a mounting portion 102, the bottom plate 101 is provided with a plurality of fixing holes 103, the fixing holes 103 are used to install expansion bolts and fix the bottom plate 101 to the ground through the expansion bolts, the mounting portion 102 is provided on the bottom plate 101, and the flip portion 200 is flipably connected to the mounting portion 102 around a horizontal axis. In this embodiment, the bottom plate 101 is provided, and the fixing holes 103 are provided on the bottom plate 101, which makes it more convenient for the base 100 to be installed on the ground through fasteners such as expansion bolts, making the installation of the circuit breaker assembly flip tool of the utility model more convenient, and can prevent the base 100 from sliding during the process of flipping the circuit breaker, thereby achieving a better flipping effect.

[0050] In some embodiments of the present invention, Figures 1 to 3 As shown, the mounting portion 102 includes two mounting blocks 104 and a rotating shaft 105, the mounting blocks 104 are provided with bearings 106, the rotating shaft 105 is installed on the two bearings 106, and the flip portion 200 is connected to the rotating shaft 105 and is located between the two mounting blocks 104. Specifically, the two mounting blocks 104 can be respectively provided with two bearing holes, the two bearing holes are coaxial, the two bearings 106 are respectively installed in the two bearing holes and fixed by a retaining ring, the rotating shaft 105 is rotatably installed on the two bearings 106, the two ends of the rotating shaft 105 can extend to the outside of the opposite side of the two mounting blocks 104 and be provided with holes, and the hole can be provided with a limiting bolt 107 to play a limiting role to prevent the rotating shaft 105 from sliding along the axial direction, and the flip portion 200 can be sleeved outside the rotating shaft 105.

[0051] In this embodiment, such an arrangement enables the turning part 200 to turn more smoothly, thereby achieving a better turning effect on the circuit breaker.

[0052] In some embodiments of the present invention, Figures 1 to 3 As shown, the flip part 200 is provided with a support part 205, and when the flip part 200 is in the second state, the support part 205 abuts against the bottom of the crank box 400 to support the crank box 400. Specifically, when the flip part 200 is in the first state, the support part 205 is located at the top of the flip part 200, and after the crank box 400 is installed, the support part 205 is located at one side of the crank box 400 and abuts against the side wall of the crank box 400, and when the flip part 200 is flipped to the second state, the support part 205 is located at the bottom end of the crank box 400 and abuts against the bottom of the crank box 400.

[0053] In this embodiment, a support portion 205 is provided. When the flipping portion 200 flips from the first state to the second state, the support portion 205 can support the circuit breaker, thereby reducing the pressure on the fasteners between the flipping portion 200 and the crank box 400, thereby preventing the fasteners from being bent or damaged due to excessive pressure, and achieving better practicality.
