Abstract

The present invention proposes a control panel movement system using a movable trolley optimized for the movement of a control panel, which can prevent the risk of tipping over during the movement of the control panel and ensure the safety of the worker. The system may include a first movable trolley supporting one side of the control panel and a second movable trolley supporting the other side of the control panel, which is supported on one side by the first movable trolley, and moving the control panel together with the first movable trolley.

Description

Mobile cart and movement system of control panel using the same The present invention relates to a trolley. More specifically, it relates to a movable trolley and a control panel moving system using the same, which can prevent the risk of tipping over a control panel and ensure the safety of a worker when moving a control panel. A control panel is a core control device of an industrial automation system and is a closed structure in which various electrical and electronic components, such as PLCs (Programmable Logic Controllers), relays, circuit breakers, timers, terminal blocks, and HMIs (Human Machine Interfaces), are integrated and installed. The control panel is connected to various industrial machines, such as production facilities, air conditioning systems, robot automation equipment, and logistics systems, and performs functions such as power supply, equipment control, status monitoring, and protection, thereby ensuring that the entire system operates safely and efficiently. These control panels are generally manufactured from metal materials such as steel or aluminum, and depending on their size and specifications, they weigh between tens and hundreds of kilograms. Furthermore, many are vertically elongated with large aspect ratios, making it difficult to ensure stability during transportation. A mobile trolley refers to a movable support frame structure for transporting heavy loads or large equipment in a manual or semi-automatic manner. Generally, a mobile trolley is equipped with multiple casters on the lower part and may be configured to include a frame structure capable of supporting a load and fixing means on the upper part. Meanwhile, because the control panel has a vertical structure with a high aspect ratio, its center of gravity can easily shift during movement, and there is a high risk of it tipping over due to uneven floor surfaces, slopes, or sudden turns while in an unbalanced state. This presented a problem that could not only cause safety accidents for workers but also lead to damage to the control panel. In addition, as assembled control panels must be moved to various work zones within the factory during the manufacturing process, the demand for mobile carts for in-house cargo transport is steadily increasing. Accordingly, when moving control panels, it is necessary to use a dedicated mobile trolley that takes into account the size, center of gravity, and fixed parts suitable for the characteristics of the control panel, rather than a general mobile trolley. FIGS. 1 and FIGS. 2 are perspective views of a moving system according to one embodiment of the present invention. FIG. 3 is a perspective view showing a movable trolley according to one embodiment of the present invention. FIG. 4 is a side view of a movable trolley according to one embodiment of the present invention. FIG. 5 is a front view of a movable trolley according to one embodiment of the present invention. FIG. 6 is a top view of a movable trolley according to one embodiment of the present invention. FIGS. 7 and FIGS. 8 are illustrative diagrams for explaining the operation of a movable trolley according to an embodiment of the present invention. It should be noted that technical terms used in this specification are used merely to describe specific embodiments and are not intended to limit the invention. Furthermore, unless specifically defined otherwise in this specification, technical terms used in this specification should be interpreted in the sense generally understood by those skilled in the art to which the invention pertains, and should not be interpreted in an overly broad or overly narrow sense. Additionally, if a technical term used in this specification is an incorrect technical term that fails to accurately express the spirit of the invention, it should be understood as being replaced by a technical term that can be correctly understood by those skilled in the art. Moreover, general terms used in this invention should be interpreted according to their prior definitions or the context, and should not be interpreted in an overly narrow sense.
