[0041] like Figures 1-5 As shown, this embodiment provides a circuit breaker assembly vehicle, including a vehicle body 1 and two angle steels 2.
[0042] The vehicle body 1 includes a frame 11 and wheels 12, with the wheels 12 connected to the bottom of the frame 11. Two angle steels 2 are spaced apart on the top surface of the frame 11 along a first direction. Both angle steels 2 extend along a second direction and their inner angles are opposite each other. Both angle steels 2 are movably connected to the top surface of the frame 11 and can move closer or further apart along the first direction. The circuit breaker is configured to be clamped and fixed between the two angle steels 2.
[0043] The first direction and the second direction are perpendicular to each other.
[0044] In practice, firstly, according to the specifications of the circuit breaker to be assembled, adjust the spacing between the two angle steels 2 along the first direction. Then, clamp and fix the circuit breaker between the two angle steels 2. The vehicle body 1 can then be moved to transport the circuit breaker and provide assembly support. Afterwards, when assembling the next circuit breaker, if the specifications of the next circuit breaker are different from the previous one, the distance between the two angle steels 2 can be adjusted again according to the dimensions of the circuit breaker to be assembled. That is, each time only the angle steels 2 need to be moved, without needing to replace the circuit breaker assembly vehicle.
[0045] The circuit breaker assembly vehicle provided in this embodiment has two movable angle steels 2 on the top surface of the frame 11, so that the distance between the two angle steels 2 can be adjusted. The two angle steels 2 with different distances can adapt to circuit breakers of different specifications and sizes, so that the circuit breaker assembly vehicle can be used for circuit breakers of various specifications, which is conducive to improving equipment utilization and reducing production costs.
[0046] like Figure 1 As shown, in some embodiments, the frame 11 includes a plurality of columns 111 spaced apart. The top surfaces of the plurality of columns 111 are connected in sequence by a plurality of first connecting crossbars 112, and the bottom surfaces of the plurality of columns 111 are connected in sequence by a plurality of second connecting crossbars 113. With this configuration, the frame 11 has a simple structure, is not only convenient and quick to manufacture, but is also easy to move, thus improving the convenience of use.
[0047] For example, the column 111, the first connecting crossbar 112 and the second connecting crossbar 113 can all be made of steel pipes and can be connected to each other by welding.
[0048] Preferably, the number of uprights 111, first connecting crossbars 112 and second connecting crossbars 113 are all set to four, the frame 11 is a cuboid frame, and the two ends of each angle steel 2 are movably connected to the two opposite first connecting crossbars 112.
[0049] For example, the first direction can be the length direction of the cuboid frame, and the second direction can be the width direction of the cuboid frame.
[0050] With this configuration, the cuboid frame is easy to manufacture and the angle steel 2 is easy to install and position. For example, when the second direction is the width direction of the cuboid frame, the angle steel 2 can be installed parallel to that width direction.
[0051] like Figure 4 and Figure 5 As shown, in some embodiments, the frame 11 further includes a reinforcing rod 114 extending along a first direction, with the middle portion of each angle steel 2 movably connected to the top surface of the reinforcing rod 114.
[0052] By setting the reinforcing bar 114, the overall strength of the frame 11 is increased, and additional support is formed at the bottom of the angle steel 2, thereby improving the stability when clamping and fixing the circuit breaker.
[0053] In some embodiments, the frame 11 further includes a flat plate, which is fixedly connected to the space formed by a plurality of second connecting crossbars 113. Laying a flat plate at the bottom of the frame allows for the temporary placement of tools needed during assembly, thus improving convenience.
[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the circuit breaker assembly vehicle further includes spring dampers 5, which are arranged in a one-to-one correspondence with the wheels 12, and are disposed between the wheels 12 and the bottom of the frame 11. For example, the frame 11 is a cuboid frame, and the wheels 12 can be disposed at the four corners of the bottom of the cuboid frame. Correspondingly, the spring dampers 5 are also disposed at the four corners of the bottom of the frame 11.
[0055] With this configuration, the spring damper 5 can form a gravity self-balancing adjustment system, effectively preventing the circuit breaker from tipping over when placed on one side, and fully protecting the lives of the staff. For example, when the load on one side of the frame 11 exceeds 100kg, flatness compensation is automatically triggered, with a compensation amount Δh ≤ 0.3mm / m, making the circuit breaker more stable when installed on the frame 11.
[0056] The specific structure of the spring damper 5 is a mature existing technology in this field, and will not be described in detail here.
[0057] like Figure 5 As shown, in some embodiments, the top surface of the frame 11 has two mounting areas, each corresponding to one of the two angle steels 2. Each mounting area includes multiple mounting hole groups 3, which are spaced apart along a second direction. Each mounting hole group 3 includes multiple mounting holes 31 spaced apart along a first direction. The angle steel 2 can be connected to a corresponding mounting hole 31 by threaded fasteners 4. Threaded connection using threaded fasteners 4 results in a simple structure, easy installation and disassembly, and high connection strength. Threaded fasteners 4 include, but are not limited to, bolts.
[0058] For example, such as Figure 5 As shown, each mounting area on the top surface of the frame 11 is provided with three mounting hole groups 3, located on the two first connecting crossbars 112 opposite each other along the second direction and on the reinforcing bar 114, respectively. Each mounting hole group 3 includes three mounting holes 31, which are arranged at intervals along the first direction. Figure 5 Taking the orientation as an example, from left to right, the distance between the first mounting hole 31 and the second mounting hole 31 is L1 = 100 ± 0.5 mm, and the distance between the second mounting hole 31 and the third mounting hole 31 is L2 = 70 ± 0.5 mm. That is, there is a three-stage adjustable gap between the two angle steels 2, which can be adapted to three models of circuit breakers: W650, W800, and W1000.
[0059] like Figure 5 As shown, in some embodiments, each mounting hole group 3 further includes an elongated hole 32, which extends along a first direction, and the plurality of mounting holes 31 in each mounting hole group 3 are connected to the elongated hole 32.
[0060] With this setup, when the position of angle steel 2 needs to be adjusted, loosen the threaded fastener 4 so that the threaded fastener 4 can slide in the elongated hole 32 and move the angle steel 2. When the angle steel 2 is in place, move the threaded fastener 4 into the mounting hole 31 at the current position and tighten the threaded fastener 4 to fix the angle steel 2. The structure is simple and the operation is convenient.
[0061] like Figure 4 As shown, in some embodiments, each angle steel 2 has a first notch 211 and a plurality of positioning holes 212 on the first support arm 21 connected to the top surface of the frame 11. When the circuit breaker is clamped between two angle steels 2, the circuit breaker can be fixed to the corresponding positioning hole 212. The first notch 211 is configured to allow the circuit breaker's sealing pole to be placed.
[0062] For example, the first arm 21 has six oblong positioning holes 212, each adapted to the positioning holes of different types of circuit breakers, so that the circuit breaker can be stably positioned in the corresponding position during assembly and to avoid uncontrollable displacement. The first arm 21 has two first notches 211. After the circuit breaker is fixed to the corresponding positioning hole 212, the sealing poles of phase A and phase C of the circuit breaker are placed at the corresponding first notches 211, so as to successfully complete the installation of the circuit breaker.
[0063] like Figure 2 As shown, in some embodiments, a second notch 221 is provided at one end of the second arm 22 of each angle steel 2 that is perpendicular to the top surface of the frame 11. By providing the second notch 221, the sealing plates on both sides of the circuit breaker can be avoided, preventing the sealing plates from colliding with the angle steel 2.
[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
