Description

Technical Field

[0001] This utility model relates to the field of current transformer installation technology, specifically to a retractable platform for installing high-voltage current transformers. Background Technology

[0002] High-voltage switchgear typically consists of current transformers, voltage transformers, grounding switches, and circuit breaker trolleys. High-voltage current transformers are quite large and heavy. Currently, most installations of high-voltage current transformers rely on one person manually lifting the transformer while another tightens the bolts. This installation method is labor-intensive and extremely dangerous. Alternatively, platforms can be used to support the transformers. However, due to the structural characteristics of high-voltage switchgear, the installation location of high-voltage current transformers is often deep within the cabinet, requiring platforms designed to reach the installation position. This results in large platforms, making transportation extremely inconvenient. Furthermore, high-voltage current transformers come in various shapes and heights, leading to poor platform versatility.

[0003] Therefore, how to design a small, height-adjustable, and scalable auxiliary platform is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1: The specific structure of this utility model is as follows:

[0029] Please refer to the appendix. Figure 1-5 This utility model discloses a telescopic platform for installing high-voltage current transformers, comprising a movable frame 1, with swivel casters 9 equipped with brakes mounted at the four corners of the bottom of the frame 1. This facilitates movement of the platform between different installation sites. Once at the installation position, the swivel casters 9 are secured by brakes to ensure platform stability.

[0030] The retractable platform also includes a support section 2, a support platform 4, and a support beam 8.

[0031] The support part 2 has a slide rail 3 and its height is adjustable. The support part 2 has a U-shaped structure, and the slide rail 3 is installed on both vertical plates on its sides. The height-adjustable structure of the support part 2 is an adjustment assembly 6 composed of a threaded rod and nuts. There are four sets of adjustment assemblies 6, which are located at the four corners of the bottom surface of the support part 2. The support part 2 is fitted onto the threaded rod and supported by four nuts. The height of the support part 2 is adjusted by rotating the nuts. When it is necessary to adjust the height of the support part 2, the nuts of the four adjustment assemblies 6 are rotated to raise or lower the support part 2, thereby achieving precise adjustment of the height of the support part 2.

[0032] The support platform 4 is slidably connected to the slide rail. The support platform 4 is provided with a platform with a side protection structure and a positioning column on the side of the support platform 4. The side protection structure can prevent the high voltage current transformer from sliding or falling on the support platform.

[0033] The support platform 4 has an "H" shaped structure, and the lower part of both side plates is provided with multiple threaded holes that are linearly distributed. All the threaded holes are connected to the lower cavity of the support platform 4.

[0034] The first end of the support beam 8 is rotatably connected to the side of the frame 1, and the second end is provided with a notch that can engage a positioning post to form a support structure for the support beam 8. The outer side of the frame 1 is also provided with a protruding post, which is used to support the notch of the support beam 8 when the support beam 8 is not in use.

[0035] like Figure 1 As shown, after the support platform 4 extends, the support beam 8 is rotated so that the notch engages with the positioning column. At this point, the support beam 8 and the support platform 4 form an angle, thus forming a diagonal bracing support structure. This diagonal bracing support structure can withstand the weight of the high-voltage current transformer.

[0036] When the platform is not in use, the support beam 8 is rotated so that its notch engages with the protruding post on the outer side of the frame 1, thus storing the support beam 8. The support platform 4 is then retracted, and the telescopic platform is moved to a suitable storage area.

[0037] In summary, the telescopic platform of this utility model is small in size, making it easy to move and transport in narrow spaces. Furthermore, the height of the support platform can be easily adjusted by the adjustment components to meet the installation requirements of high-voltage current transformers at different heights.

[0038] This utility model's telescopic platform utilizes the cooperation of support beams and positioning columns to provide stable support when installing high-voltage current transformers, reducing manual labor intensity and improving the safety and efficiency of the installation process. It is reasonably designed and highly practical.

[0039] The side protection structure of the retractable platform support of this utility model can effectively prevent the high-voltage current transformer from sliding or falling during installation, further improving the safety of the installation process.

[0040] The retractable platform support of this utility model features universal casters with brakes, which enable the platform to be quickly fixed after being moved to the installation position, ensuring the stability of the installation process.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
