[0038] Example 1

[0039] like Figure 1-2 The present invention provides a circuit breaker transport protection device, comprising a frame 1, a transport platform 3, and a fixing device 4. The frame 1 is provided with a lifting and lowering device 2; the transport platform 3 is provided above the frame 1 and is used to carry the circuit breaker; the fixing device 4 is provided on the transport platform 3 and is used to fix the circuit breaker on the transport platform 3. During installation, the lifting and lowering device 2 lifts the transport platform 3 to the same height as the circuit breaker installation, making it convenient for the operator to place the circuit breaker stably on the transport platform 3. Subsequently, the fixing device 4 firmly clamps the circuit breaker from multiple directions to ensure that it will not be damaged by shaking, collision, etc. during the transport process. During the transport process, the frame 1 provides support for the entire device with its stable structure. At the same time, the lifting and lowering device 2 can flexibly adjust the height and levelness of the transport platform 3 according to actual road conditions and operational requirements to adapt to different working environments. When arriving at the designated installation location, the lifting and lowering device 2 comes into play again, accurately adjusting the transport platform 3 to the height and angle required for installation. The operator only needs to release the fixing device 4 to easily complete the installation of the circuit breaker.

[0040] Specifically, the frame 1 includes a chassis 101, and the lifting and lowering device 2 includes a plurality of lifting booms 201. The plurality of lifting booms 201 are arranged on the chassis 101, and the plurality of lifting booms 201 are in a scissor-type structure. A transfer platform 3 is arranged above the scissor-type structure. A hydraulic rod 202 is provided on the chassis 101, and the output end of the hydraulic rod 202 is connected to the scissor-type structure. When in use, the hydraulic rod 202 starts to extend and drives the lifting boom 201 of the scissor-type structure to lift the transfer platform 3, so that the transfer platform 3 rises steadily to a suitable height. When the height of the transfer platform 3 needs to be lowered, the hydraulic rod 202 contracts, driving the lifting boom 201 of the scissor-type structure to descend, thereby causing the transfer platform 3 to descend steadily. The coordinated design of the scissor-type structure and the hydraulic rod 202 can ensure that the transfer platform 3 remains stable during the lifting process, avoiding shaking or tilting, and provides a strong guarantee for the safe transportation and precise installation of the circuit breaker. At the same time, the scissor-type structure composed of multiple lifting rods 201 can evenly distribute the weight of the transfer platform 3 and the circuit breaker, reduce the pressure on the chassis 101, and improve the stability and load-bearing capacity of the entire frame 1.

[0041] Specifically, there are two groups of scissor structures, which are symmetrically connected on both sides below the transfer platform 3, and each group of scissor structures is installed with a hydraulic rod 202. Such a double scissor structure and a double hydraulic rod 202 configuration further enhance the stability and balance of the transfer platform 3 during lifting and lowering. In actual operation, the hydraulic rods 202 on both sides are started and retracted synchronously, which enables the scissor structure to drive the transfer platform 3 to lift and lower more coordinatedly, greatly reducing the risk of shaking and deviation caused by uneven force. Moreover, even if a minor fault occurs in one group of the scissor structures or the hydraulic rod 202, the other group can still maintain the normal lifting and basic stability of the transfer platform 3 to a certain extent, providing additional protection for the stable operation of the equipment, and further improving the reliability and safety of the entire circuit breaker transfer protection device.

[0042] like Figure 1-6In some embodiments, the fixing device 4 includes a bracket 401, a fixing plate 402, a lifting plate 403, a lifter 405, and a plurality of elastic sheets 406. The bracket 401 is arranged below the transfer platform 3; the fixing plate 402 is arranged below the bracket 401; the lifting plate 403 is slidably connected to the bracket 401, and the transfer platform 3 is provided with a non-circular through-hole 404 that can cooperate with the lifting plate 403, and the through-hole 404 is larger than the bottom surface of the circuit breaker; the lifter 405 is arranged on the fixing plate 402 and is used to lift and lower the lifting plate 403; a plurality of elastic sheets 406 are arranged in the through-hole 404 and are elastically connected to the hole walls of the through-hole 404 respectively. In order to improve stability during transportation, the through-hole 404 for a single model of circuit breaker can be a through-hole 404 that matches the shape of the side wall of the circuit breaker; the through-hole 404 for multiple models of circuit breakers can be a rectangular through-hole 404. During use, the lifting plate 403 is flush with the top surface of the transfer platform 3, and the circuit breaker is placed on the lifting plate 403. Then the lifter 405 is started to lower the lifting plate 403 so that the circuit breaker passes through the through hole 404. The elastic sheet 406 is clamped on the side wall of the circuit breaker under the action of the elastic connection. When the transportation is bumpy, the elastic sheet 406 absorbs the impact force of the circuit breaker under the action of elasticity, reduces the impact of the circuit breaker due to vibration, and ensures that it remains intact during transportation. In addition, the design of the bracket 401 provides a stable support for the entire fixing device 4 to avoid shaking or tilting during transportation. When the circuit breaker needs to be removed, the lifter 405 lifts the lifting plate 403, and the elastic sheet 406 is squeezed and deformed, thereby loosening the clamping of the side wall of the circuit breaker. At this time, the circuit breaker can be easily taken out of the through hole 404 to complete the transportation process.

[0043] Specifically, the upper and lower surfaces of the elastic sheet 406 adopt an arc transition. This setting allows the elastic sheet 406 to easily overcome the elastic force and move toward the wall of the through hole 404 when the lifting plate 403 passes through the elastic sheet 406, thereby reducing the occurrence of jamming. At the same time, it also makes the contact between the lifting plate 403 and the elastic sheet 406 smoother, reduces the wear on the elastic sheet 406 and the lifting plate 403, and extends the service life of the device. Moreover, this arc transition design can also prevent the elastic sheet 406 from scratching or damaging the surface of the circuit breaker during movement, further protecting the circuit breaker. In addition, a buffer pad can be provided between the elastic sheet 406 and the wall of the through hole 404. When the elastic sheet 406 moves toward the wall, the buffer pad can absorb the impact force of the elastic sheet 406, reduce the collision and noise between the elastic sheet 406 and the wall, and make the operation of the entire device more stable and quiet.

[0044] Specifically, an anti-slip pad 407 is provided on one end of the elastic sheet 406, away from the inner wall of the through-hole 404. This pad is used to prevent the circuit breaker from being jolted out of the through-hole 404 when it is subjected to vertical vibrations relative to the transfer platform 3, further enhancing the circuit breaker's securement. The anti-slip pad 407 is made of a rubber material with a high coefficient of friction. This soft material provides sufficient friction without scratching the circuit breaker surface. Furthermore, the surface of the anti-slip pad 407 has been specially treated with fine graining, further increasing friction with the circuit breaker surface. Furthermore, the anti-slip pad 407 is secured to the elastic sheet 406 with strong adhesive, ensuring that it will not fall off during long-term use. When the circuit breaker encounters vibrations during transport, the anti-slip pad 407 adheres tightly to the surface of the circuit breaker, effectively preventing it from being jolted out of the through-hole 404 due to vibrations, thus ensuring the safety and stability of the circuit breaker during transport.

[0045] In some embodiments, lifter 405 is a pneumatic cylinder fixedly connected to fixed plate 402, with its output end connected to lifting plate 403. The cylinder acts as a shock absorber, mitigating impact forces on the circuit breaker when it is jolted vertically from the transfer platform 3, thereby reducing damage to the circuit breaker. The cylinder's stroke can be adjusted to accommodate transport heights. Furthermore, the cylinder operates stably and reliably, precisely controlling the raising and lowering of lifting plate 403.

[0046] Specifically, the cylinder is connected to a pressure relief valve that can be manually adjusted to open or close. When the circuit breaker is placed on lifting plate 403, the cylinder contracts, causing lifting plate 403 to descend. The elastic sheet 406 then abuts against the sidewall of the circuit breaker. The pressure inside the cylinder increases under the weight of the circuit breaker, reducing its shock absorption efficiency. By manually adjusting the valve, some of the gas in the cylinder flows out of the pressure relief valve, reducing the pressure inside the cylinder and improving the cylinder's shock absorption function to meet the shock absorption requirements of circuit breakers of different weights.

[0047] Specifically, each bracket 401 is provided with a shock-absorbing groove 4011, which is positioned relative to the lifting plate 403. Multiple protrusions 4012 extend from the lifting plate 403, each engaging with a corresponding groove 4011. A spring 4013 is installed within each groove 4011, each spring 4013 being connected to a corresponding protrusion 4012. During use, the protrusions 4012 move along the grooves 4011. During transportation, the springs 4013 provide shock-absorbing force to the protrusions 4012, further enhancing the shock-absorbing effect of the lifting plate 403. Furthermore, the spring constant of the spring 4013 can be selected and adjusted based on the actual use scenario. For harsh and bumpy transportation environments, a spring 4013 with a higher spring constant can be selected to enhance shock absorption. For relatively stable transportation environments, a spring 4013 with a lower spring constant can be selected to ensure a certain degree of shock absorption while preventing excessive spring 4013 from interfering with the normal raising and lowering of the lifting plate 403. At the same time, the inner wall of the shock-absorbing groove 4011 is smoothed to reduce the friction of the protrusion 4012 during movement, ensuring that the protrusion 4012 can move smoothly along the shock-absorbing groove 4011, so that the shock-absorbing effect of the spring 4013 can be more effectively exerted, further ensuring the safety of the circuit breaker during transportation.

[0048] like Figure 1-2 In some embodiments, four wheels 5 are disposed beneath the frame 1, each equipped with a stopper. The wheels 5 facilitate transport of the device, and the stopper secures the wheels 5 relative to the device. A disc brake system can be employed to secure the wheels 5 through friction. The stopper ensures that the device remains stably fixed during circuit breaker installation, preventing positional shifting during installation due to accidental slippage of the wheels 5. This effectively ensures accurate and stable circuit breaker installation, thereby improving installation efficiency and quality and providing a solid foundation for the subsequent normal operation of the circuit breaker.
