The technical solution adopted by the utility model to solve the technical problem is: the high-voltage cabinet maintenance insulation stool includes a base, a fixed pulley frame, a fixed pulley, a universal pulley frame, a universal pulley, and an insulating stool surface. The two lower lifting connecting plates are fixed on the side, and the middle of the left and right lower lifting connecting plates on both sides is hinged together with a hinged connecting rod, and the upper ends of the four lower lifting connecting plates are hinged to connect the four upper lifting Connecting plates, the four upper lifting connecting plates are hinged with hinged connecting rods in the middle, and the insulating stool surface is fixed on the top of the four upper lifting connecting plates, and the lower lifting plate and the connecting shaft of the screw nut are fixed on the screw nut under the base, and the screw nut Mesh and connect the lead screw installed axially under the base, the left end of the lead screw is connected to the crank handle, the two ends of the connecting shaft of the lower lifting plate and the screw nut are fixed on the lower end of the lower right lifting connecting plate, and are fixed on both sides on the right side under the base Fixed pulley frame is housed, fixed pulley is adorned on the fixed pulley frame, universal pulley frame is fixed on the left side below the base, and universal pulley is adorned on the universal pulley frame. the

The beneficial effects of the utility model are: the high-voltage cabinet maintenance insulation stool solves the special tools required due to the height of the high-voltage cabinet, eliminates unsafe factors, ensures the safe operation of equipment and the reliability of social power consumption, and ensures personal safety and equipment. Safe, easy to use, high work efficiency. the

Description of drawings

The following will be described in detail with embodiments in conjunction with the accompanying drawings. the

Figure 1 is a structural diagram of an insulating stool for maintenance of a high-voltage cabinet. the

In the figure, 1-insulated stool surface; 2-upper lifting connecting plate; 2-1-lower lifting connecting plate; 3-hinge connecting rod; 4-cradle; 5-universal pulley frame; 6-universal pulley; 7 -fixed pulley frame; 8-fixed pulley; 9-base; 10-leading screw; 11-screw nut; 12-lower lifting plate and screw nut connecting shaft. the

Detailed ways

Embodiment, with reference to accompanying drawing 1, the high-voltage cabinet maintenance insulation stool is to fix two lower lifting connecting plates 2-1 on the left side on both sides of the base 9, and the right side of the base 9 uses the lifting plate and the screw nut connecting shaft 12 to connect the two The lower lifting connecting plate 2-1 is hingedly connected on the base 9, and the middle part of the lower lifting connecting plate 2-1 on the left and right sides of the base 9 is connected together with the hinged connecting rod 3 hinges. The upper ends of four lower lifting connecting rods 2-1 are hinged with two hinged connecting rods 3. The tops of the four upper lifting connecting plates 2 fix the insulating stool surface 1. Below base 9 lifting plate and screw nut connection shaft 12 are fixed on screw nut 11, and screw nut 11 engages the lead screw 10 that axially sets below base 9, and the left end of lead screw 10 connects crank 4. Below base 9, both sides, left side, adorn fixed pulley frame 7, adorn fixed pulley 8 on fixed pulley frame 7, fix universal pulley frame 5 on both sides, left side below base 9, adorn universal pulley 6 on universal pulley frame 5. the

The method of using the insulating stool for maintenance of high-voltage cabinets is: when it is not used for stepping up, the insulating stool surface 1 can be folded with the upper and lower lifting connecting plates 2 and 2-1, which can be used as a transport tool, such as for high-voltage cabinets When the maintenance pedal is high, shake the handle 4, and the screw nut 11 drives the lower lifting plate 2-1 on the right side of the base 9 through the leading screw 10 to move to the left, so that the insulating stool surface 1 is raised to the required height and can be used. the
