Description

Technical Field

[0001] This utility model relates to a folding maintenance platform for prefabricated substations and a prefabricated substation. Background Technology

[0002] In recent years, with the rapid development of high-speed rail and the upgrading of railway power supply equipment, prefabricated substations have gradually become an important component of high-speed rail and railway construction. Currently, the maintenance platform and foundation walls of existing railway power prefabricated substations are constructed on-site through formwork erection, rebar reinforcement, and cast-in-place concrete. The substation mounting surface is created by welding channel steel to the rebar inside the foundation walls on both sides, followed by cast-in-place concrete, leaving the top 20mm of the channel steel exposed. Additionally, red brick masonry is required for the foundation support walls and access steps. Because railway power prefabricated substations are placed in the field, the formwork erection, rebar reinforcement, and cast-in-place concrete construction of the maintenance platform, as well as the masonry of the support walls, are all difficult. The maintenance platform railings are installed on-site using expansion bolts, resulting in poor stability and unreliability. Utility Model Content

[0003] The technical problem to be solved by this utility model is that, in view of the inconvenience of constructing the existing prefabricated substation foundation structure maintenance platform, this utility model provides a prefabricated prefabricated prefabricated substation maintenance platform and prefabricated substation that can be easily transported.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A box-type substation folding maintenance platform, including platform steps and railings, is characterized by the following structural features:

[0006] The platform pedal includes a main pedal and an angle pedal. A first hinge is installed on one side of the main pedal, and a first connecting seat is provided on the other side. The main pedal is hinged to one end of the pedal support leg, and a second connecting seat is provided on the other end of the pedal support leg. The angle pedal is equipped with an angle bracket.

[0007] The fence includes a main fence and corner fences, and a third connecting seat is provided on the bottom edge of the main fence;

[0008] The main pedal and the main fence are respectively arranged on each side of the box-type substation box, and the first connecting seat of the main pedal is hinged to the third connecting seat of the main fence.

[0009] The connection between the main pedal and the main fence is provided with a fence fixing buckle to prevent the main fence from folding;

[0010] When not in operation, the main pedal and the main fence are folded relative to each other;

[0011] In the working state, the main pedal and the main fence are unfolded. The connection between the main pedal and the main fence is fixed by the fence fixing buckle. The second connecting seat of the pedal support leg is connected and fixed. The corner pedal is supported by the corner bracket and installed at the corner of the box-type substation box. The corner pedal and the main pedal are connected to form a continuous working platform, and the corner fence is installed on the outside of the corner pedal.

[0012] Preferably, the main pedal includes a rectangular frame made of tubing, on which a patterned plate is laid. The first hinge is installed on one side of the patterned plate, and the first connecting seat is installed on the other side of the patterned plate. The frame is provided with a pivot pin seat for connecting the pedal support leg.

[0013] Preferably, the main fence includes multiple fence panels and multiple posts. Adjacent fence panels are connected by the posts. Each fence panel is divided into two individual fence units along the height direction and is hinged to each other via fence hinges. Each post is divided into two individual post units along the height direction and is hinged to each other via post hinges. The fence units and post units are at the same height, allowing the fence units and post units of the main fence to fold relative to each other. The post hinge mounting points are equipped with post fixing buckles to prevent the post from folding. When the post is unfolded, the connection between two connected post units is fixed by the post fixing buckles.

[0014] Preferably, the device further includes steps, each step comprising a side frame disposed opposite to the other side frame and a reinforcing frame connecting the side frame, the side frame comprising multi-level support beams arranged along the height direction, and step plates mounted on the support beams.

[0015] Preferably, the corner fence includes a corner post and two corner fence panels, one side of each of the two corner fence panels is connected to the corner post, and the two corner fence panels are perpendicular to each other to form a 90-degree angle.

[0016] Based on the same inventive concept, this utility model also provides a prefabricated substation, which includes a box-type enclosure and a foundation, wherein the box-type enclosure is mounted on the foundation, and its structural features are as follows:

[0017] The base of the enclosure is provided with a second hinge around its perimeter, and the second hinge is hinged to the first hinge of the box-type substation folding maintenance platform via a pivot pin.

[0018] The foundation is a prefabricated foundation;

[0019] During transportation, both the main pedal and the main railing are folded to the bottom side panel of the box.

[0020] During maintenance, the main pedal and the main fence are unfolded. The connection between the main pedal and the main fence is fixed with the fence fixing buckle. The second connecting seat of the pedal support leg is connected and fixed to the foundation. The corner pedal is supported by the corner bracket and installed at the corner of the box. The corner pedal and the main pedal are connected to form a continuous working platform, and the corner fence is installed on the outside of the corner pedal.

[0021] Preferably, a connecting plate is fixed around the base of the housing, and the second hinge is fixed on the connecting plate.

[0022] Preferably, a screw is pre-embedded in the foundation, and the second connecting seat is connected and fixed to the screw.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1) The folding maintenance platform of this utility model adopts a steel structure and is pre-assembled in the factory. During the shipment and transportation process, the maintenance platform can be folded to the bottom of the box-type substation and fixed securely. During the on-site hoisting and installation process, the folding maintenance platform can be opened and the foot support legs can be fixed, which can meet the maintenance and repair needs of the box-type substation, greatly reducing the installation and construction time of the box-type substation. It is especially convenient for the situation where the construction of existing railway lines needs to be carried out during the nighttime maintenance window.

[0025] 2) The box-type substation foundation of this utility model adopts the factory prefabrication and casting mode. During on-site installation, the prefabricated foundation components only need to be hoisted onto the excavated foundation, which greatly reduces the construction time of the box-type substation foundation. It is particularly suitable for the conditions where construction can only be carried out at night during the renovation of existing railway lines.

[0026] 3) When installing the box-type substation of this utility model, since the maintenance platform adopts a steel structure, it is not necessary to build the maintenance platform support wall on site. Only the civil engineering area of ​​the box-type substation foundation needs to be leveled, which greatly reduces the amount of on-site civil engineering work and speeds up the construction progress.

[0027] 4) When constructing the folding maintenance platform of this utility model, the maintenance platform railing is designed in an integrated and standardized manner, and the reliability requirements of the maintenance platform railing are met through mechanical analysis.

[0028] 5) The folding maintenance platform of this utility model also takes into account the steps for climbing, which meets the requirements of on-site maintenance personnel to go up and down. At the same time, during non-maintenance periods, the steps can be folded inward to form a maintenance platform fence, and locks are installed to achieve the anti-theft function.
