Description

Hidden folding maintenance bench for electrical panel cabinet Technical Field The invention relates to the technical field of maintenance stools, in particular to a hidden folding maintenance stool for an electrical cabinet. Background The electrical panel cabinet is used as a key control and protection node of the power system, and the periodic inspection, test and maintenance of elements such as an internal breaker, a relay, an instrument, a wiring terminal and the like are necessary work for guaranteeing the long-term stable and reliable operation of the system. When working on components at the upper part or the top of the tray cabinet, maintenance staff always needs to be at a certain height, and currently, the maintenance staff generally rely on carrying an independent maintenance stool (or step stool) to the scene. However, the stool independent of the tray cabinet exposes a plurality of increasingly outstanding limitations, inconvenience and potential safety hazards in practical application, namely, firstly, the portability is poor, the common maintenance stool is used for guaranteeing the stability, the structure is provided with a certain volume and weight, and maintenance staff (especially when carrying tools and instruments at the same time) moves and carries the stool to and from different tray cabinets or operation points, so that the labor is wasted, and the working efficiency is low when multi-point and continuous maintenance is needed. Secondly, the space interference problem is serious, and a safe operation channel is reserved in front of and behind a cabinet in the places such as a transformer substation equipment area, a power distribution room and the like, but the space is limited. The temporarily placed maintenance stool can occupy the channel which is not wide, so that other people are prevented from passing, stool feet of the temporarily placed maintenance stool are very easy to collide with and interfere with a cable laid on the ground, a pipe ditch cover plate or other peripheral equipment bases, tripping risks exist, and damage to a precise cable is also possible. Thirdly, there is obvious security risk, in the extremely tight or uneven ground in space leads to the unable steady occasion of placing of maintenance bench, and maintainer probably is forced to risk to use unstable temporary object bed hedgehopping such as toolbox, equipment packing box, or barely stand on the toe operation, and these actions have greatly increased personnel and have slipped, step on the sky and lead to falling the injured risk, belong to serious overhead operation potential safety hazard. Fourth, the management and storage are inconvenient, a large number of independent stools need to be stored in a special warehouse in a non-overhaul period, confusion is easy to generate in management, loss or damage is caused, and meanwhile, the storage cost is increased. In summary, it has been difficult for existing models to meet the modern power operation and maintenance requirements of high efficiency, safety and specifications. Therefore, an innovative scheme capable of fundamentally changing the current situation is needed in the industry, namely, an embedded or attached maintenance auxiliary lifting device which can be conveniently combined with a cabinet body, does not need to occupy extra channel space, has high integration level, is safe and reliable to use and is convenient to manage is developed, so that the operation efficiency is improved, the potential safety hazard is eliminated, and the intensive management of operation and maintenance tools is realized. Disclosure of Invention The invention aims to provide a hidden folding type maintenance stool for an electrical cabinet, which aims to solve the problems in the background technology. The invention is realized by the following scheme: The utility model provides a hidden foldable maintenance bench of electrical panel cabinet, includes the support frame, the support frame outside is provided with folding mechanism, the support frame bottom is provided with installation mechanism, support frame top fixedly connected with support column, with folding bench function and installation function integration in an organic whole. The integrated design obviously reduces the space and the management cost required by independently storing the stool, and provides a special auxiliary ascending scheme which can be used at any time and is convenient to store for the overhaul of the electrical cabinet; Folding mechanism includes the fixing base, fixing base fixedly connected with support column right side, the fixing base inboard is provided with the telescopic link, telescopic link one end is rotated and is connected with the connecting seat, connecting seat one end fixedly connected with support arm one, support arm one top fixedly connected with support arm two, support arm two inboard fixedly connected with overhauls bench body, support frame top fixedly connect
