Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment installation technology in subway stations, and in particular to an installation device for electromechanical equipment in subway stations. Background Technology

[0002] In subway stations, the installation of electromechanical equipment (such as ventilation systems, power control cabinets, fire-fighting equipment, etc.) and supporting pipelines (cable trays, fire water pipes, etc.) is a key part of the construction.

[0003] The power control cabinet in a subway station is a special control cabinet used for centralized control, power distribution, monitoring and management of various electromechanical equipment in the station. It is an important part of the subway station's power system and ensures the normal operation of the station and the safety of the equipment.

[0004] Traditional power control cabinet installation methods typically rely on on-site welding, bolt fixing, and manual adjustment and positioning. Equipment installation, pipeline laying, and fixing of light equipment (cameras, broadcasting) must be completed in stages, with a lack of coordination between the stages, resulting in long construction cycles. After the electromechanical equipment in subway stations is positioned, pipeline supports need to be re-erected, and repeated adjustments lead to resource waste. Subway station electromechanical equipment has diverse specifications, while existing fixed supports are of uniform size and cannot be flexibly adjusted, easily leading to installation misalignment or insufficient stability. Pipelines are usually fixed with independent supports, without linkage with the equipment installation structure, resulting in poor overall rigidity. Continuous vibration during subway operation can easily cause pipeline supports to loosen or even detach from the equipment connection, posing safety hazards. Furthermore, fine-tuning of subway station electromechanical equipment relies on manual handling, increasing construction intensity. Therefore, to solve this problem, it is necessary to design a subway station electromechanical equipment installation device. Utility Model Content

It integrates heavy equipment installation components, pipeline installation components, and light equipment installation components via an L-shaped base, enabling simultaneous installation of equipment, pipelines, and light accessories. This avoids the repetitive adjustments required in traditional step-by-step construction, shortening the construction period. The pipeline installation components are directly fixed to the connecting blocks of the heavy equipment installation components. The horizontal mounting plate of the light equipment installation components shares the same L-shaped mounting plate as the pipeline installation components, simplifying the installation process. Horizontal and vertical adjustment rods are used to adjust the displacement of the L-shaped base via adjusting bolts. The vertical adjustment rod is fine-tuned according to the equipment height. The connecting block and the limiting block form a rigid four-corner clamp through the horizontal, vertical, and vertical adjustment rods, preventing equipment displacement. Pulling the handle down to press down the fixed support plate applies a vertical pre-tightening force to the support fixing block, suppressing pipeline loosening due to vibration. The integrated moving and fixing components enable moving, positioning, and fixing without relying on manual handling, reducing construction intensity. The structure is relatively simple and easy to use. Attached Figure Description
