Description

Technical Field

[0001] This utility model relates to the field of circuit breaker enclosure storage technology, and specifically to a enclosure stacking device for a common-enclosure circuit breaker. Background Technology

[0002] A common-enclosure circuit breaker is a high-voltage switchgear that houses three-phase circuit breakers within a single enclosure. It offers advantages such as compact structure, high reliability, and convenient maintenance. Three-phase electricity is a common power supply method in power systems, widely used in industry, commerce, and some large residential areas. Three-phase electricity refers to a power source composed of three alternating current potentials with the same frequency, equal amplitude, and phases differing by 120° sequentially. These three alternating current potentials are typically referred to as phase A, phase B, and phase C.

[0003] The utility model patent document CN222775167U discloses a box structure for a common box type circuit breaker, including a lower box, an upper box, terminals, a cover, explosion-proof panels, and an explosion-proof guard plate. The lower box is sealed to the upper box, and a sealed cavity is formed between the lower box and the upper box. The upper box is sealed to the terminals through the cover, and the terminals extend into the sealed cavity.

[0004] See Figures 1 to 3 The upper surface of the enclosure 11 has two terminal mounting bosses 111, with a partition channel 112 between them. Each terminal mounting boss has three connection ports, each for mounting terminals for three-phase power. In the production line for common-enclosure circuit breakers, the enclosure is first transported to the production line entrance, and then workers assemble the components of the common-enclosure circuit breaker into the enclosure. Figure 1 The traditional transportation method involves workers directly stacking multiple boxes 11 on a chassis 1; then using a forklift to transport the chassis and boxes. However, vibrations are easily generated during forklift transportation, and the stacked boxes collide with each other, which can easily lead to defects and damage to the boxes, reducing their quality.

[0005] Therefore, in order to avoid collisions between stacked enclosures, there is an urgent need in this technical field for a enclosure stacking device for common-enclosure circuit breakers. Utility Model Content

Detailed Implementation

[0038] This utility model embodiment provides a cabinet stacking device for a common-enclosure circuit breaker. The overall technical concept is as follows:

[0039] The chassis is placed on the ground, and the first isolation bracket is placed on the chassis. The horizontal and vertical support rods of the isolation bracket form a "T"-shaped area. A box is placed in each "T"-shaped area. The middle of one side of the box is placed on the horizontal support rod, and the other side of the box is placed on the vertical support rod. The box is balanced and stable in the "T"-shaped area, thus forming the first layer of box isolation components. The isolation bracket is fixedly equipped with buffer strips, which play a role in buffering and reducing vibration. The buffer strips also increase friction and prevent the box from sliding off the isolation bracket.

[0040] Then, a second isolation bracket is placed on the first layer of box isolation components. The horizontal support rod of this second isolation bracket is placed in the dividing channel of the first layer of box isolation components. Next, boxes are placed in the "T"-shaped area of ​​the second isolation bracket to obtain the second layer of box isolation components. Multiple box isolation components are stacked layer by layer, and the chassis and the top box isolation component are tied with ropes. Finally, the chassis is removed by a forklift, and the stacked boxes are transported to the designated position on the production line.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] See Figures 1 to 12 The first embodiment of this utility model.

[0043] A stacking device for a common-enclosure circuit breaker includes:

[0044] Chassis 1; Box isolation assembly 2;

[0045] The enclosure isolation assembly 2 includes a first enclosure 21, a second enclosure 22, and an isolation bracket 25. The isolation bracket 25 includes a first longitudinal support rod 251, a second longitudinal support rod 252, and a transverse support rod 253. The middle part of the first longitudinal support rod 251 is fixedly connected to the left end of the transverse support rod 253, and the middle part of the second longitudinal support rod 252 is fixedly connected to the right end of the transverse support rod 253. Buffer strips 254 are fixedly provided on the upper and lower surfaces of the first longitudinal support rod 251, the second longitudinal support rod 252, and the transverse support rod 253.

[0046] The upper surface of the first housing 21 has two terminal mounting bosses 111, and a partition channel 112 is provided between the two terminal mounting bosses 111. The width of the transverse support rod 253 is smaller than the width of the partition channel 112, the height of the transverse support rod 253 is greater than the height of the partition channel 112, and the length of the transverse support rod 253 is greater than the length of the partition channel 112. The structure of the second housing 22 is the same as that of the first housing 21.

[0047] The middle position of the right side of the lower surface of the first box 21 is placed on the transverse support rod 253, the left side of the lower surface of the first box 21 is placed on the first longitudinal support rod 251, the middle position of the left side of the lower surface of the second box 22 is placed on the transverse support rod 253, the right side of the lower surface of the second box 22 is placed on the second longitudinal support rod 252, and there is a gap between the first box 21 and the second box 22.

[0048] Two or more of the aforementioned box-type isolation components 2 are stacked one on top of the other, with the bottom isolation bracket 25 placed on the chassis 1. Among the two adjacent box-type isolation components 2, the horizontal support rod 253 of the upper isolation bracket 25 is placed in the partition channel of the lower first box 21 and the partition channel of the second box 22.

[0049] The beneficial effects or advantages of this utility model are as follows: An isolation bracket 25 is set between adjacent boxes, and the buffer strip 254 set in the isolation bracket 25 effectively reduces vibration. The isolation bracket 25 prevents the upper box from contacting the lower box, avoids collisions between stacked boxes, and improves the quality of the boxes. According to the dividing channel on the upper surface of the box, a matching transverse support rod 253 is set to improve the support stability of the isolation bracket 25 during stacking, which helps to keep the box position stable during transportation.

[0050] In the two adjacent box-type isolation components 2, the lower first box 21 and the second box 22 support the upper horizontal support rod 253, which prevents the two adjacent boxes from contacting and colliding. The height of the horizontal support rod 253 is the same as the height of the first longitudinal support rod 251 and the second longitudinal support rod 252; the buffer strip 254 is a rubber buffer strip 254, and the first longitudinal support rod 251, the second longitudinal support rod 252, and the horizontal support rod 253 are all aluminum alloy support rods.

[0051] At the bottommost housing isolation assembly 2, the isolation bracket 25 separates the first housing 21, the second housing 22, and the chassis 1. There are gaps between the first housing 21 and the chassis 1, and between the second housing 22 and the chassis 1, allowing workers to easily reach into these gaps to move the first housing 21 and the second housing 22. Compared to manufacturing a single piece of material, the isolation bracket 25 of this invention uses less material and is lighter in weight.

[0052] Furthermore, the chassis 1 has longitudinal fork insertion holes 12.

[0053] The beneficial effects of this technical solution are: it facilitates the handling of the chassis with a forklift, thereby transporting stacked boxes.

[0054] Furthermore, the chassis 1 and the uppermost box isolation assembly 2 are connected by ropes 26.

[0055] The beneficial effects of this technical solution are: improving the positional stability of the stacked box isolation components 2 during transportation and effectively preventing the stacked box isolation components 2 from collapsing.

[0056] Furthermore, a marking line 211 is provided at the middle position on the left and right sides of the first housing 21.

[0057] The beneficial effects of this technical solution are as follows: When placing the first box 21 on the isolation bracket 25, the operator can quickly and accurately align the middle right side of the lower surface of the first box 21 with the first horizontal support rod 2531 and the left side of the lower surface of the first box 21 with the first vertical support rod 251 by referring to the marking line 211, and align the middle left side of the lower surface of the first box 21 with the left end of the first horizontal support rod 2531; this helps the first box 21 to be placed in a balanced and stable position on the isolation bracket 25. The marking line 211 can be an ink marking line, which is easy to erase.

[0058] The operation mode of the enclosure stacking device for a common-enclosure circuit breaker in this embodiment:

[0059] Workers first place the first isolation bracket 25 on the chassis 1, then place the first box 21 and the second box 22 into the "T"-shaped area of ​​the first isolation bracket 25, forming the first layer of box isolation components 2. Next, a second isolation bracket 25 is placed, with its horizontal support rod 253 positioned in the dividing channel between the first box 21 and the second box 22. The first box 21 and the second box 22 are then placed into the "T"-shaped area of ​​the second isolation bracket 25, forming the second layer of box isolation components 2. This process is repeated, with multiple box isolation components 2 stacked layer by layer. Finally, ropes 26 are used to secure the box isolation components 2 and the chassis 1. A forklift is used to remove the pallets, and the stacked boxes are transported to a designated location on the production line. The buffer strips 254 on the isolation bracket 25 effectively reduce vibration during transport, preventing collisions between stacked boxes and protecting them. When the boxes are needed, the ropes 26 are untied, and the boxes and isolation brackets 25 are removed layer by layer from top to bottom.

[0060] See Figures 13 to 15 The second embodiment of this utility model.

[0061] Furthermore, the enclosure isolation assembly 2 also includes a third enclosure 23 and a fourth enclosure 24. There are two transverse support rods 253, namely a first transverse support rod 2531 and a second transverse support rod 2532. One-quarter of the first longitudinal support rod 251 is fixedly connected to the left end of the first transverse support rod 2531. Three-quarters of the first longitudinal support rod 251 is fixedly connected to the left end of the second transverse support rod 2532. One-quarter of the second longitudinal support rod 252 is fixedly connected to the right end of the first transverse support rod 2531. Three-quarters of the second longitudinal support rod 252 is fixedly connected to the right end of the second transverse support rod 2532. The structure of the third enclosure 23 and the structure of the fourth enclosure 24 are the same as the structure of the first enclosure 21.

[0062] The first box 21 has its lower surface middle right position on the first transverse support rod 2531, and its lower surface left position on the first longitudinal support rod 251. The second box 22 has its lower surface middle left position on the first transverse support rod 2531, and its lower surface right position on the first longitudinal support rod 251. The third box 23 has its lower surface middle right position on the second transverse support rod 2532, and its lower surface left position on the first longitudinal support rod 251. The fourth box 24 has its lower surface middle left position on the second transverse support rod 2532, and its lower surface right position on the second longitudinal support rod 252. The first box 21, the second box 22, the third box 23, and the fourth box 24 are all spaced apart.

[0063] In two adjacent box-type isolation assemblies 2, the first horizontal support rod 2531 of the upper isolation bracket 25 is placed in the partition channel of the lower first box 21 and the partition channel of the lower second box 22, and the second horizontal support rod 2532 of the upper isolation bracket 25 is placed in the partition channel of the lower third box 23 and the partition channel of the lower fourth box 24.

[0064] The beneficial effects of this technical solution are as follows: Four "T"-shaped areas are formed between the first longitudinal support rod 251, the second longitudinal support rod 252, the first transverse support rod 2531, and the second transverse support rod 2532 of the enclosure isolation assembly 2. The first enclosure 21, the second enclosure 22, the third enclosure 23, and the fourth enclosure 24 are placed in the four "T"-shaped areas respectively, which improves the support stability and facilitates the stacking of more layers of the enclosure isolation assembly 2 on the chassis 1.
