Abstract
Description
Technical Field
[0001] This utility model relates to the field of substation supporting equipment, specifically to a modular steel structure walking platform for substations. Background Technology
[0002] Modular substations (MDS), as integrated secondary power exchange equipment for power supply in large factories, mines, and industrial parks, are characterized by convenient installation and easy maintenance. To facilitate subsequent cable installation, MDS manufacturers often design their installation locations at a higher elevation, measured in meters. While this increases the installation elevation and facilitates wiring and inspection, it significantly hinders the movement of inspection personnel and materials during routine maintenance.
[0003] In existing technologies, access to the various compartments of the modular transformer often involves multiple independent steel ladders. Each compartment has its own ladder at its entrance, with the top of the ladder connected to the main body of the transformer structure to secure its position. However, this type of independent ladder presents several problems: Firstly, because independent ladders cannot connect different rooms, staff wishing to move from one room to another must first descend to the ground and then walk around to reach the other room, which is time-consuming and laborious. Secondly, due to the narrow width of the independent ladders, there is generally no escape route. In the event of an accident requiring evacuation of the transformer, trampling and crowding are likely to occur, posing a safety hazard. Utility Model Content
[0004] This utility model proposes a steel structure walking platform for modular substations to solve the problems of needing to detour when entering and exiting the modular substation room via independent ladders in the prior art, as well as the problem that the existing independent ladders are too narrow and cannot be set up with escape passages, which easily leads to trampling and crowding when evacuation is required.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A modular substation steel structure walking platform includes a main platform and a first step and a second step respectively disposed at both ends of the main platform. The main platform includes:
[0007] The walking frame is a horizontally arranged long strip frame with several horizontal partitions on its upper surface. The partitions are evenly distributed along the axis of the walking frame and are perpendicular to the walking frame. A walking grid is laid between adjacent partitions.
[0008] The support rod is set vertically, with its top connected to the lower surface of the walking frame and its bottom having a horizontal mounting plate with mounting holes.
[0009] The concrete support is provided below the supporting rod, and the top surface is provided with embedded bolts, the embedded bolts pass through the mounting holes of the mounting plate, and then the mounting plate and the concrete support are locked by mounting nuts.
[0010] The bearing platform is embedded beside the modular transformer substation, and the concrete support is arranged on the bearing platform.
[0011] The first and second staircases are both provided with U-shaped insertion rods with downward openings, which are inserted into the hollow insertion sleeves at the end of the walking frame.
[0012] In particular, the walking grating is a U-shaped plate with downward openings, and the vertical parts at both ends of the walking grating are clamped on both sides of the walking frame.
[0013] In particular, the thickness of the walking grating is consistent with the height of the partition plate.
[0014] In particular, the walking grating is further provided with a kick plate and a handrail.
[0015] In particular, the walking frame is provided with a bending section at the end, forming an L-shaped structure surrounding the modular transformer substation, the walking grating above the bending section is fixedly connected with the bending section, the first staircase is arranged at the end of the bending section, and the second staircase is arranged at the end of the walking frame away from the bending section.
