[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0027] Example 1
[0028] The utility model provides a retractable switch cabinet electrical testing trolley, such as Figure 1 As shown, the retractable switch cabinet test trolley includes a first push-pull part 1 and a second push-pull part 2, wherein the first push-pull part and the second push-pull part are arranged opposite to each other to form the main frame of the switch cabinet test trolley, and the first push-pull part and the second push-pull part are telescopically connected. By changing the positional relationship between the first push-pull part and the second push-pull part, the width of the switch cabinet test trolley is adjusted to adapt to test cabinets of different cabinet widths; the upper part of the first push-pull part is adjustably connected to the first push plate 4, and the upper part of the second push-pull part is adjustably connected to the second push plate, the first push plate 4 and the second push plate are respectively located on both sides of the main frame, and the adjustably connected first push plate and second push plate are used to adapt to different switch cabinets.
[0029] Specific: such as Figure 2 As shown, the first pushing and pulling part 1 includes a first wheel support 11 and a first locking support 12, one end of the first wheel support 11 and the first locking support 12 is provided with a through hole, and the other end of the first wheel support and the first locking support is connected with a first connecting support 13; since the first pushing and pulling part 1 and the second pushing and pulling part 2 are arranged relative to each other, the second pushing and pulling part includes a second wheel support and a second locking support, one end of the second wheel support and the second locking support is provided with a through hole, and the other end of the second wheel support and the second locking support is connected with a second connecting support; the first wheel support, the first locking support, the second wheel support, the second locking support and the connecting support are all U-shaped structures, and the bottom of the end of the first wheel support and the second wheel support away from the through hole is provided with a sliding wheel, and the sliding wheel is used to slide on the guide rail so that the electrical testing trolley can be moved to the front of the switch cabinet. The upper part of the first push-pull part 1 is adjustably connected to the first push plate 4, and the upper part of the second push-pull part is adjustably connected to the second push plate. Specifically, the first connecting support 13 and the second connecting support are fixedly connected to the first push plate bracket 3 and the second push plate bracket respectively, and the first push plate bracket and the second push plate bracket are adjustably connected to the first push plate and the second push plate respectively. The adjustable connection method is preferably an adjustable connection through bolts and nuts, and the specific positions of the first push plate and the second push plate are adjusted according to different switch cabinets.
[0030] In this embodiment, the first push-pull portion and the second push-pull portion are telescopically connected, specifically: the first wheel support and the second wheel support are aligned, the first locking support and the second locking support are aligned, and a first telescopic plate 8 is provided on the inner wall of the first wheel support and the second wheel support for telescopically connecting the first wheel support and the second wheel support; a second telescopic plate is provided on the inner wall of the first locking support and the second locking support for telescopically connecting the first locking support and the second locking support; the telescopic structure is realized as follows: Figure 3 As shown, the first and second telescopic plates are each provided with a plurality of limiting holes 81. By aligning the through holes with the different limiting holes, elastic clips are then used to secure the first and second push-pull portions. In addition to elastic clips, pins or other structures can also be used for securing, thereby achieving a telescopic connection between the first and second push-pull portions. The positional relationship between the first and second push-pull portions can be changed by adjusting the first and second telescopic plates, depending on the width of the test cabinet to be tested. This allows the overall width of the test trolley to be adjusted to accommodate the width of the test cabinet to be tested.
[0031] In this embodiment, the first locking strut and the second locking strut are respectively provided with a first locking piece and a second locking piece at one end away from the through hole, and the first locking strut and the second locking strut are also provided with a first blocking piece 14 and a second blocking piece. Specifically: the first locking strut and the second locking strut are respectively provided with a first mounting hole and a second mounting hole at one end away from the through hole. The first locking piece passes through the first mounting hole, with one end extending into the first locking strut and the other end extending out of the first locking strut. The end of the first locking piece extending into the first locking strut sequentially passes through the first connecting strut and the first blocking piece; the second locking piece passes through the second mounting hole, with one end extending into the second locking strut and the other end extending out of the second locking strut. The end of the second locking piece extending into the second locking strut sequentially passes through the second connecting strut and the second blocking piece. And, as Figure 4 As shown, the end of the first locking piece that extends into the first locking support has two first connection holes 71 formed on either side of the first blocking piece. The end of the second locking piece that extends into the second locking support has two second connection holes formed on either side of the second blocking piece. Furthermore, the outer surfaces of the first and second locking supports are provided with a first handle and a second handle, respectively. The handles extend through the first locking support through the two first connection holes and are slidably connected to the ends of the first handle, and extend through the second locking support through the two second connection holes and are slidably connected to the ends of the second handle. Specifically, taking the first handle as an example, the first locking support is provided with a first handle and a first locking piece. After the first handle and the first locking piece are fixed, the first handle can be slid to move the first locking piece. When the test trolley enters the switch cabinet, the first handle is slid to insert the first locking piece into the locking groove inside the switch cabinet, thereby securing the test trolley. The first blocking piece 14 and the second blocking piece are used to limit the movement of the first and second locking pieces, ensuring that they can only move laterally.
[0032] In the embodiment of the present invention, a retractable switch cabinet electrical testing trolley is used, and the specific method of the electrical testing operation is as follows:
[0033] First, the width of the test trolley is adjusted by adjusting the first and second retractable plates according to the width of the test cabinet to be tested, so as to adapt to the width of the test cabinet to be tested. The positions of the first and second push plates are adjusted according to the type of switch cabinet in the test cabinet to adapt to different switch cabinets. The retractable switch test trolley is pushed into the switch cabinet by the first and second handles. The sliding wheels of the test trolley are placed on the tracks on the guide rails. The operator pushes the first and second handles of the test trolley to the valve door of the switch cabinet. The first and second push plates open the valve door inside the switch cabinet, exposing the charged parts in the contact box. When the valve door is opened, the first and second locking plates are inserted into the locking slots of the switch cabinet. Finally, the operator can perform the test. The test trolley of this embodiment can meet the test requirements of different cabinets. The retractable structure can accommodate different cabinet widths. It does not require multiple test trolleys to meet the test requirements of distribution cabinets with different cabinet widths, greatly improving the efficiency of the operator's maintenance work.
[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
