Description

Technical Field

[0001] The utility model relates to the technical field of power plant maintenance equipment, in particular to a mobile maintenance platform for power plant equipment. Background Art

[0002] A power plant refers to a facility that produces and supplies electricity. It is usually composed of generators, transformers, transmission lines and distribution equipment. A power plant can use different energy sources to generate electricity, including fossil fuels (such as coal, natural gas and oil), nuclear energy, hydropower, wind energy, solar energy and biomass energy. A power plant mobile maintenance platform refers to a movable device used to perform equipment inspection and maintenance work within a power plant.

[0003] In the prior art, mobile maintenance platforms that can be raised and lowered often use scissor-type lifts. However, a protective plate is often fixed on the top of the existing scissor-type lifts to prevent workers from falling when performing maintenance work. However, when the scissor-type lift is not in use, the protective plate on the top will occupy a large space volume, affecting the overall storage. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a mobile maintenance platform for power plant equipment to solve the technical problem in the prior art that the fixed protective plates will occupy a large space volume when the elevator is not in use, affecting the overall storage.

[0006] A plurality of scissor arms are cross-movably arranged between the fixed frame and the sliding frame from bottom to top, the tops of the plurality of scissor arms are movably connected with a lifting platform, and protective side panels are movably connected on both sides of the lifting platform, and the inner sides of the two groups of protective side panels are movably connected with adjusting screw rods that penetrate the lifting platform, and the adjusting screw rods play the role of driving the protective side panels to rise and fall, and a rotating wheel is fixed on the top of the adjusting screw rod;

[0007] Both ends of the adjusting screw rod are movably connected to the limit block, and the limit block is fixedly connected to the protective side plate. The top and bottom outer sides of the adjusting screw rod are fixed with limit rings located inside the limit block, and the limit block is provided with a limit groove matched with the limit ring. Under the action of the limit ring, the limit block and the adjusting screw rod are movably limited and connected, which will not affect the rotation of the adjusting screw rod.

[0008] A fixing rod is fixed inside the fixing frame, a force rod is fixed between one group of the scissor arms, hydraulic rods are movably arranged on both sides between the fixing rod and the force rod, guide rails are fixed on the top of the base and one end of the bottom of the lifting platform, and guide grooves matching the guide rails are opened inside the two groups of sliding frames.

[0009] By adopting the above technical solution, under the action of the hydraulic rod, multiple groups of intersecting scissor arms can be unfolded, so that the lifting platform can be raised and lowered. The staff stand on the lifting platform, and then the staff can perform maintenance on the power plant equipment at different heights. The staff can manually lift the two groups of protective side panels to make the protective side panels rise to protect the staff on the lifting platform, and when not in use, the two groups of protective side panels can be retracted downward, so that when not in use, they will not occupy a large space volume, which is convenient for overall storage, transportation and relocation.

[0010] The utility model is further configured that guide strips penetrating the lifting platform are fixed at both ends of the inner sides of the two groups of protective side panels, and sliding grooves matching the protective side panels and the guide strips are opened on both sides of the interior of the lifting platform.

The top and bottom outer sides of the adjusting screw rod 11 are fixed with a limit ring 13 located inside the limit block 12, and the limit block 12 is provided with a limit groove matched with the limit ring 13. Under the action of the limit ring 13, the limit block 12 and the adjusting screw rod 11 are movably limited and connected, which will not affect the rotation of the adjusting screw rod 11.

[0024] The staff can manually lift the two sets of protective side panels 10, so that the protective side panels 10 rise to protect the staff on the lifting platform 9, and when not in use, the two sets of protective side panels 10 can be retracted downward, so that when not in use, they will not occupy a large space volume, which is convenient for overall storage, transportation and relocation;
