Background
Along with the improvement of the technology of water conservancy and hydropower engineering in China, the burden of overhaul and operation maintenance personnel is reduced in order to facilitate overhaul of equipment, and hoisting equipment is required to be arranged in places where major equipment is installed in underground plants so as to facilitate hoisting and replacing the equipment during overhaul of the equipment. However, because underground factory building space is narrow and small, equipment is arranged compactly, and arranged in rows or arranged in rows, a lot of difficulties are brought to the arrangement of hoisting equipment, and the main problems are as follows:
1. the underground cavern is limited by geological conditions in the underground powerhouse, and for the stability of the cavern, the space size of the underground powerhouse is as small as possible under the condition of meeting the functional requirements, so that the difficulty of excavation and supporting of the underground cavern is reduced. This requires the equipment layout space of each system to be as compact as possible, and places high restrictions and requirements both on the floor layout of the equipment and on the space layout of the equipment, which also places high requirements on the installation of the lifting equipment.
2. The equipment in each equipment room in the underground factory building is more, so that the equipment management and pipeline connection are convenient, the equipment in each equipment room is elaborately designed during arrangement, or is arranged in a row or a column, and is limited by the arrangement space, only one main transportation channel and one object hanging hole are generally arranged, and the equipment is required to be moved to the main transportation channel and the object hanging hole from the equipment installation position, and the equipment cannot span due to the fact that the equipment is large in weight and large in size; according to the field conditions, a fixed lifting hook is generally arranged just above the equipment, and the arrangement only meets the requirement that the equipment is lifted in the original position, and the equipment is transferred to a transportation channel after being lifted in the original position, even manpower is needed to assist in transferring, a large amount of manpower and material resources are consumed, and especially the safety risk of heavy parts in the transferring process is large.
3. Some facilities are provided with linear monorail hoisting facilities, and hoisting tracks of the facilities are basically arranged in a linear mode, generally arranged directly above the facilities or arranged on a main channel, and only can meet the requirements of hoisting and moving the facilities in situ or on a main transportation channel. For equipment rooms with equipment installed, the hoisting equipment does not greatly help the maintenance of the equipment; if equipment is hoisted to the main transportation channel from the original position, some field personnel adopt a mode of 'inclined pulling and inclined hoisting', so that wheels of the hoisting equipment operate under the working condition of deviating the center line of the track laterally, and a lot of insecurities exist in the hoisting process of the equipment.
According to the characteristics that equipment is arranged compactly in the equipment room in the range of an underground factory building, the weight is large, other equipment is difficult to span for hoisting, and a transport passage is few, in order to solve the problems of equipment safety and convenient hoisting and transportation, the in-line equipment in-line hoisting can be met by designing a line, the in-line equipment in-situ hoisting can be met, the in-situ hoisting can be conducted safely according to the overhaul requirement of the equipment, the in-situ hoisting can be conducted on the main transport passage, and the equipment hoisting and transportation requirements can be met. So that the hoisting process of the large equipment is safe, reliable, time-saving and labor-saving, the space limitation is reduced, and the efficiency is high.
