Description

Technical Field

[0002] Low-voltage universal circuit breakers are important electronic components in low-voltage switchgear. There are many models and specifications of universal circuit breakers in low-voltage switchgear. The product carrying current ranges from 500A to 6300A, and the corresponding product dimensions range from 310 (width) × 340 (depth) × 320 (height) to 800 (width) × 500 (depth) × 450 (height), and the weight ranges from 40-240kg. Because the universal circuit breaker product has more dimensions and specifications, it is heavier and is installed at a higher height in the low-voltage switchgear compartment, generally 500-1400mm.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] The core of the utility model is to provide a low-voltage universal circuit breaker installation tool. By setting a mobile lifting platform 1, the labor intensity of carrying and lifting the low-voltage universal circuit breaker to the installation height is reduced, and the safety risk is reduced. By setting a sliding platform 6, the low-voltage universal circuit breaker can be installed in place conveniently and quickly to improve the installation efficiency of the low-voltage universal circuit breaker.

[0047] Please refer to Figure 1 and Figure 2 A low-voltage universal circuit breaker installation tool includes a mobile lifting platform 1, a hydraulic drive device 2, a support frame 3 and a sliding platform 4.

[0048] Specifically, a hydraulic drive device 2 is provided on the mobile lifting platform 1, and the hydraulic drive device 2 drives the mobile lifting platform 1 to perform lifting movements to adapt to the installation height of the low-voltage universal circuit breaker. The support frame 3 is fixed to the top of the mobile lifting platform 1, and the support frame 3 is horizontally arranged. The sliding platform 4 is movably arranged on the top of the support frame 3, and the sliding platform 4 is arranged parallel to the support frame 3. The support frame 3 serves to connect the mobile lifting platform 1 and the sliding platform 4. The low-voltage universal circuit breaker can be installed in place conveniently and quickly through the sliding platform 4 to improve the installation efficiency of the low-voltage universal circuit breaker.

[0049] The low-voltage universal circuit breaker installation tooling set up in the above manner can reduce the labor intensity of long-distance transportation and lifting of the circuit breaker to the installation height by setting up a mobile lifting platform 1, while reducing safety risks. By setting up a sliding platform 4, the circuit breaker can be installed in place conveniently and quickly, thereby improving the accuracy of the installation position.

[0050] In the above embodiment, the mobile lifting platform 1 includes a bottom frame 11, a lifting bracket 12 and a lifting platform 13. The bottom frame 11 is a rectangular frame and a universal wheel 5 is provided on the bottom circumference of the bottom frame 11. A handle 6 is provided on one side of the bottom frame 11. The lifting bracket 12 is a foldable structure. The lifting bracket 12 is liftable and arranged on the bottom frame 11. The first end of the lifting bracket 12 is connected to the inner circumferential wall of the bottom frame 11. The output end of the hydraulic drive device 2 is connected to the lifting bracket 12. The lifting platform 13 is fixed to the second end of the lifting bracket 12 and is arranged parallel to the bottom frame 11.

[0051] It should be noted that, through the cooperation of the universal wheel 5 and the handle 6, the bottom frame 11 can move freely, thereby driving the lifting bracket 12 and the lifting platform 13 to move freely. The hydraulic drive device 2 can drive the lifting bracket 12 to move up and down, driving the lifting platform 13 to always be in a horizontal position, thereby transporting and lifting the low-voltage universal circuit breaker to an installation position of a corresponding height, and realizing the fast and convenient installation of the low-voltage universal circuit breaker to different positions.

[0052] In the above situation, the hydraulic drive device 2 includes a fixed support 21, a hydraulic cylinder 22 and a foot pedal 23. The fixed support 21 is fixed in the bottom frame 11, the hydraulic cylinder 22 is fixed to the fixed support 21, the output end of the hydraulic cylinder 22 is connected to the lifting bracket 12, and the foot pedal 23 is arranged on the outside of the bottom frame 11, and the foot pedal 23 is connected to the hydraulic cylinder 22.

[0053] It can be understood that the hydraulic cylinder 22 is activated by stepping on the foot pedal 23, and the hydraulic cylinder 22 drives the lifting bracket 12 to perform lifting movement, driving the lifting platform 13 to perform lifting movement to adapt to installation positions at different heights.

[0054] Furthermore, the support frame 3 includes a frame body 31 and a pull plate 32 . The frame body 31 is disposed on the top of the lifting platform 13 . The pull plate 32 is disposed around the frame body 31 . The pull plate 32 fixes the frame body 31 to the lifting platform 13 by bolts.

[0055] It should be noted that a pull plate 32 is provided in the circumferential direction of the frame body 31 to fix the frame body 31 on the top of the lifting platform 13. In this embodiment, the frame body 31 is fixed by the pull plate 32 and bolts, but in real life, there is no restriction on the fixing form of the frame body 31, as long as the above technical effect can be achieved.

[0056] In the above embodiment, the frame body 31 includes a first rectangular frame and a second rectangular frame. The first rectangular frame is arranged in cooperation with the lifting platform 13, and the second rectangular frame is supported and erected on the top of the first rectangular frame. The length of the second rectangular frame is less than that of the first rectangular frame.

[0057] It can be understood that setting the length of the second rectangular frame to be smaller than the length of the first rectangular frame can avoid interference of the low-voltage universal circuit breaker during installation.

[0058] On the basis of the above embodiment, the sliding platform 4 includes a linear guide rail 41, a sliding base plate 42, a limit column 43 and a limit baffle 44. The linear guide rail 41 is fixed to the top of the second rectangular frame and extends along the width direction of the second rectangular frame. The sliding base plate 42 is moved along the linear guide rail 41 through a slider. The limit column 43 is fixed to the top of one end of the sliding base plate 42. The limit baffle 44 is vertically arranged at the bottom of both ends of the sliding base plate 42 and between the linear guide rails 41. The limit baffle 44 extends along the height direction of the frame body 31.

[0059] It should be noted that, by setting a linear guide rail 41, the sliding base plate 42 can slide along the linear guide rail 41 through a slider, by setting a limit column 43 to limit the position of the low-voltage universal circuit breaker, and by setting a limit baffle 44 to limit the sliding distance of the sliding base plate 42 on the linear guide rail 41, the sliding base plate 42 is prevented from slipping.

[0060] In the above embodiment, the linear guide rail 41 is fixed to the top of the second rectangular frame by T-bolts.

[0061] It is understandable that in this embodiment, the linear guide rail 41 is fixed to the top of the second rectangular frame by T-bolts, but in actual life, there is no limitation on the connection method between the linear guide rail 41 and the second rectangular frame, as long as the above-mentioned technical effect can be achieved.

[0062] The low-voltage universal circuit breaker in this embodiment includes a circuit breaker body 7 and a shell 8. The shell 8 is pre-installed on the partition of the low-voltage switch cabinet. The circuit breaker body 7 is moved to the low-voltage switch cabinet through the installation tool, and the circuit breaker body 7 is installed in the shell 8. For the structure of other parts of the low-voltage switch cabinet, please refer to the prior art and will not be repeated in this article.

[0063] In the above situation, a group of slide rails 9 are provided in the shell 8, and the slide rails 9 are movably arranged along the inner wall of the shell 8 and are arranged corresponding to the sliding bottom plate 42. When the circuit breaker body 7 is installed, the slide rails 9 are pulled out from the shell 8 to correspond to the two sides of the sliding bottom plate 42, so that the circuit breaker body 7 is located between the slide rails 9. Furthermore, the slide rails 9 are provided with card grooves 10, and the card grooves 10 are carded with the card connection parts on both sides of the circuit breaker body 7. Through the sliding bottom plate 42, the card connection parts on both sides of the circuit breaker body 7 can be conveniently and quickly slid horizontally to the position of the card groove 10 on the slide rail 9, accurately carded into the card groove 10, and the circuit breaker body 7 is supported by the slide rails 9, so that the circuit breaker body 7 is smoothly installed in the shell 8.

[0064] In summary, the low-voltage universal circuit breaker installation tool provided by the utility model is lowered to the lowest position by the hydraulic cylinder 22, the circuit breaker body 7 is placed on the sliding bottom plate 42, and the whole is moved to the front of the low-voltage switch cabinet, and the hydraulic cylinder 22 is driven to telescopically act on the lifting bracket 12, and the lifting platform 13 is lifted to the height of the low-voltage switch cabinet partition, and the slide rails 9 on both sides of the shell 8 are pulled out, and the circuit breaker body 7 is slid to the position of the slot 10 of the slide rail 9 through the sliding bottom plate 42, and the lifting platform 13 is lowered to the slot 10 of the slide rail 9 to clamp the circuit breaker body 7, and the circuit breaker body 7 and the slide rail 9 are pushed into the shell 8 together, and the installation is completed.
