Problems solved by technology

[0002] At present, in the tubular hydroelectric generator set, the upper and lower side inlet tubes are passed in the form of ladders, because oil and water will adhere to the surface of the ladder during the operation, maintenance and other work of the unit, resulting in the passage of people There is slippage during the process, and among large-scale units, the length of the entry tube is long, and it is difficult for personnel to pass through, and it is difficult to transport goods or tools during the maintenance period, which consumes a lot of manpower and material resources for the power station, and there are potential safety hazards
[0003] In response to this problem, there are different solutions on the market, such as simple devices such as one-way hydraulic drive modules and gravity hydraulic lifting devices. This type of product has key defects such as cumbersome installation, simple safety measures, and difficult maintenance. Difficulties in use, and dismantling and maintenance during the maintenance period require a lot of manpower and time, which affects the time cost of the power station
In addition, the location of the inlet tube of the hydropower station is small, and the pipelines and circuits are complicated, which makes the installation, disassembly, repair and maintenance of existing products time-consuming and laborious.

Abstract

The invention provides a modular hydraulic lifting device for a hydropower station generator set. The modular hydraulic lifting device comprises a control mechanism and a driving mechanism which are located outside an entrance barrel, and a transmission module and an embarkation platform which work in the longitudinal direction of the entrance barrel. The top of the transmission module extends outof the entrance barrel to be connected with the control mechanism, the embarkation platform moves up and down through the transmission module, and a safety anti-falling mechanism is installed on a transverse extending rod at the top of the transmission module. The motion alarm lamps and the lighting devices are mounted at the top and the bottom of the transmission module, a control system comprising an electrical integration module, a safety locking module and a hydraulic driving module is arranged in the control mechanism, and the electrical integration module is in modular design and can bereplaced in time, so that the maintenance time cost is reduced. The modular hydraulic lifting device adopts a split assembly structure, and is rapid to install and convenient and safe to maintain.
