Method for installing bridge crane main beam of pump station main power house

Abstract

The invention discloses a mounting method for a bridge crane main beam of a pump station main power house. The mounting method comprises the following steps that S1, a bridge crane track beam and a supporting system are erected; s2, bridge crane track beams are connected with the supporting system, and the bridge crane track beams inside and outside the installation room are connected to form track beams; s3, an upstream side end beam and a downstream side end beam of the installation room are hoisted; s4, the first main beam is hoisted and translated; s5, hoisting a second main beam; s6, bridge crane accessory equipment is installed; and S7, transversely moving the whole bridge crane. According to the invention, the time waste of a large amount of cutting-off process time for the appearance quality of the structure and before decoration construction in the existing sky and ground anchoring mode is avoided; the safety risk increased due to the fact that the crane directly enters the building and is limited by the space is avoided, the adverse effect on the stability of the building due to point stress in the hoisting process is avoided, the hoisting construction of the main beam of the bridge crane and the auxiliary components does not cause any influence on civil construction in space, and parallel operation is achieved among all working procedures; and the process interval time is greatly shortened.

Description

technical field [0001] The invention relates to the field of installation of water conservancy and hydropower equipment, in particular to a method for installing a main beam of a bridge machine in a main powerhouse of a pumping station. Background technique [0002] Pumping stations that draw water from rivers (channels or lakes) are generally divided into two layouts: with diversion canals and without diversion canals. When the distance between the water source and the control elevation of the irrigation area is long, and the topography of the site is flat, an arrangement with a diversion canal is adopted. The diversion canal leads the water from the water source to the front of the pump room, and the pump room is close to the irrigation area, which can shorten the water outlet pipeline. length. When the irrigation area is close to the water source, or the ground slope of the site is steep, the layout of the pump station without diversion canal is often adopted, that is, t...

Problems solved by technology

[0005] The technical problem solved by the present invention is to provide a method for installing the main girder of the bridge crane in the main powerhouse of the pumping station. In the prior art, the distance between the highest point of the double main girder bridge crane and the top and bottom of the powerhouse is insufficient, and it is inconvenient to pre-embed the sky anchor and ground anchor. Since the frame structure of the installation room has been capped, the height cannot meet the problem of the extension of the crane arm
