[0002] The lifting platform is a hoisting machinery for vertically conveying people or objects, and is also a device for vertically conveying in logistics systems such as factories and automatic warehouses, and various plane conveying devices are often installed on the lifting platform as connecting devices of conveying lines at different heights, and the lifting platform is also widely used in high-altitude installation, maintenance and other operations.

[0003] The existing patent with the publication number CN219031635U proposes a lifting platform for maintenance, and the air device is provided with a convex rod, which is vertically arranged at the end point of the rotating plate and embedded in the slide inside the sliding block. When the convex rod moves, it will exert a pushing force on the sliding block, causing the sliding block to slide along the mounting plate to the side. At this time, the movable plate will become more inclined, and the table top will move downward, thereby achieving height adjustment of the table top.

[0004] Although the lifting platform can stably lift the height, the length of the table top is fixed and cannot be stably extended, and the position of the base needs to be frequently adjusted during power maintenance, resulting in a long maintenance time. UTILITY MODEL CONTENTS

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a lifting platform for power maintenance, comprising a base, a lifting rod is arranged at the upper end of the base, a fixed plate is arranged at the upper end of the lifting rod, a lifting frame is arranged at the upper end of the fixed plate, an extension structure is arranged on one side of the lifting frame, the extension structure comprises an oil cylinder fixedly arranged on one side of the lifting frame, a sliding groove is formed at the bottom end of the lifting frame, a connecting piece is slidably arranged in the sliding groove, the output end of the oil cylinder is fixedly connected with one side of the connecting piece, the upper end of the connecting piece penetrates into the lifting frame and is fixedly connected with an extension plate, and a plurality of rollers are rotatably connected to the lower end of the extension plate.

[0007] Preferably, a protective door is rotatably connected to one side of the lifting frame, a latch is arranged on one side of the upper end of the lifting frame, and a hole is formed in the upper end of the protective door below the latch.

[0008] Preferably, a limiting piece is fixedly arranged on one side of the lifting frame at the rear end of the protective door.

[0009] Preferably, the connecting piece is in the shape of a U-shaped piece.

[0010] Preferably, the lower end of the base is fixedly provided with universal wheels on both sides.

[0011] Preferably, the upper end of the extension plate is fixedly provided with a baffle on the front side.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1) By setting the extension structure, when the operating personnel is located inside the lifting frame to maintain the circuit, the extension plate is extended by adjusting the start of the oil cylinder at a high place, without adjusting the movement of the base, the maintenance range is increased, and the maintenance time is reduced.

[0014] 2) By setting the baffle and the limiting piece, the front and rear ends of the extended extension plate can be limited, the construction personnel are protected in a larger range, and the situation that the construction personnel falls is reduced. BRIEF DESCRIPTION OF DRAWINGS
