Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and in particular to a construction work platform for a main transformer tunnel top arch corrugated plate. Background Art
[0002] In many water conservancy projects, the main transformer tunnel arch ceiling is typically constructed using steel grids or corrugated panels. This is particularly true in underground hydropower plant buildings, where large spans and high safety risks pose a significant bottleneck to hydropower construction. The main transformer tunnel arch corrugated panel construction platform is an integral component of this process. Its design and construction methods are crucial for ensuring the quality and safety of the arch panel construction, improving efficiency and reducing costs. It ensures the stability and safety of the corrugated panel during the arch construction process.
[0003] Currently, the construction of main transformer tunnel arch access platforms in China typically utilizes full-height scaffolding. However, with the rapid development of my country's hydropower resources, the proliferation of underground hydropower station projects and the accelerated construction schedule, traditional full-height scaffolding is no longer able to meet construction deadlines. Due to its bulk, high construction investment, and high construction risk, ensuring the safe construction of full-height scaffolding in the main transformer tunnel requires a large space for the platform before installation, which requires significant labor and takes a long time to set up. Furthermore, the large size and weight of full-height scaffolding means that other construction projects in the main transformer tunnel must be suspended to make way for the platform. The large size and weight of full-height scaffolding, coupled with its high-altitude construction operations, pose significant safety risks. Therefore, finding an alternative to full-height scaffolding to accelerate construction progress and improve safety is crucial and urgent. Utility Model Content
[0004] In order to solve or partially solve the problems existing in the relevant technology, the present application provides a main transformer tunnel top arch corrugated plate construction work platform, which is erected on an electric single-beam bridge crane and transferred to the next working surface through the electric single-beam bridge crane walking system.
[0005] The first aspect of the present application provides a main transformer tunnel top arch corrugated plate construction work platform, comprising: an electric single-beam bridge crane, a steel plate base, a steel truss, a diagonal web, a connecting beam, a scaffolding platform and a top working platform. The end beam of the electric single-beam bridge crane is connected to the steel truss through the steel plate base. The steel truss and the main beam of the electric single-beam bridge crane are connected through connecting beams and diagonal webs to form a bottom fixed platform. The top surface of the fixed platform is fixed with a scaffolding platform, and the top working platform is laid on the top of the scaffolding platform.
[0006] It also includes a connecting sleeve, which is arranged on the top surface of the fixed platform, and the vertical poles of the scaffolding platform are fixed in the connecting sleeve.
[0007] It also includes connecting steel plates, which are arranged on the main beam, and the connecting beam is fixedly connected to the electric single-beam bridge crane based on the connecting steel plates.
[0008] The steel truss is a triangular truss structure, including an upper chord, a lower chord, and a web. The technical solution provided by this application may have the following beneficial effects:
[0009] The present application provides a construction platform for the main transformer tunnel top arch corrugated plate. By adopting a steel truss structure combined with an electric single-beam bridge crane to replace the original full-height scaffolding structure, other parts except the necessary connecting parts are removed. After using this device, the construction difficulty is greatly reduced. Due to the reduced size and weight of this device, there is no need to set up a full-height scaffolding operating platform, and construction can be carried out using a hoist, thereby shortening the construction time and speeding up the construction progress. At the same time, due to the faster construction speed and reduced weight, personnel do not need to work at height for a long time, which greatly reduces the construction safety risk. The construction platform for the main transformer tunnel top arch corrugated plate has been optimized to reduce the construction difficulty of the main transformer tunnel top arch corrugated plate, improve construction efficiency, speed up the construction progress, reduce construction risks, and has a high value for promotion and application.

A connecting sleeve 7 is welded to the top surface of the bottom fixed platform. The uprights of the scaffolding platform 8 are fixed within the sleeve and then the scaffolding is erected. Finally, the top working platform 9 is laid. The top arch corrugated plate installation and horizontal material transportation are carried out on this formed working platform. The electric single-girder bridge crane 1 is then used to move to the next working surface.
[0025] The connecting beam 6 and the electric single-girder bridge crane 1 are fixed by welding a connecting steel plate 4 on the main beam of the electric single-girder bridge crane 1. While fixing the steel truss 3, the connecting beam 6 and the single-girder bridge crane, it is ensured that the structural bearing capacity of the single-girder bridge crane meets the requirements.
[0026] The steel plate base 2 and connecting steel plate 4 are cut, welded, and installed on-site. The steel truss 3, connecting beam 6, diagonal brace 5, and connecting sleeve 7 can all be prefabricated in advance. After the electric single-girder bridge crane is installed and the main transformer tunnel top arch corrugated plate is constructed, a crane is used to install the steel truss 3. The steel truss 3 is welded and reinforced to the electric single-girder bridge crane using the steel plate base 2 and connecting steel plate 4. After the steel truss 3 is firmly fixed, the connecting beam 6, diagonal brace 5, connecting sleeve 7, scaffolding platform 8, and top working platform 9 are installed.
