Abstract
The utility model discloses a portal crane for a hydropower station. The portal crane comprises a stander, a gate opening and closing winding mechanism, an auxiliary lifting mechanism, wagon running mechanisms, a main hoisting trolley and an auxiliary hoisting trolley, and is characterized in that the gate opening and closing winding mechanism and the auxiliary lifting mechanism are respectively arranged on the lower parts of two sides of the stander; the auxiliary hoisting trolley is arranged on a cantilever on one side of the stander, which is provided with the auxiliary lifting mechanism; and one end of the cantilever is fixedly connected with the stander, and the other end of the cantilever is connected with the stander through a lifting cable. The portal crane for the hydropower station is specially used for opening and closing a gate, blocking sewage and overhauling a dam crest of the hydropower station; a main winding mechanism and an auxiliary winding mechanism are arranged on the lower part of the stander, so that the portal crane is convenient to overhaul and maintain, and the safety and the stability of the whole portal crane are improved; the auxiliary hoisting trolley is arranged on the cantilever; when the portal crane is used for hoisting, the gravity center falls to one side of the stander, and the stability is well guaranteed; and the portal crane has the characteristics of low gravity and low wheel pressure.
Description
Technical field
The utility model relates to a kind of power station gantry crane.
Background technology
Existing power station gantry crane, its gate opening/closing hoisting mechanism and auxiliary hoisting mechanism are installed in the top or the middle part of frame, and the center of gravity of whole hoisting crane is higher; Maintenance is inconvenient; Safety performance is also poor, and the transmission of hoisting mechanism employing exposed gear, cooperates not compact.
Summary of the invention
The purpose of the utility model just provides a kind of compact conformation, center of gravity is low, security and stability is good power station gantry crane.
The power station gantry crane of the utility model; Comprise frame, gate opening/closing hoisting mechanism, auxiliary hoisting mechanism, traveling mechanism of the larger traveller, ram track brake, main crane carriage, secondary crane carriage, main crane carriage is located at the top of frame, is characterized in; Gate opening/closing hoisting mechanism, auxiliary hoisting mechanism are contained in the bottom of frame both sides respectively; The gate opening/closing hoisting mechanism links to each other with main crane carriage through enclosed gear reduction unit, steel rope and assembly pulley, and main suspension hook and equalizing bar are set on the main crane carriage, and auxiliary hoisting mechanism is connected with secondary crane carriage through enclosed gear reduction unit, steel rope and assembly pulley; Secondary crane carriage is provided with secondary suspension hook; Secondary crane carriage is placed on the cantilever of frame one side that auxiliary hoisting mechanism is housed, and cantilever one end and frame are affixed, and the other end is connected with frame through hanger rope.
The power station gantry crane of the utility model, the power station dam crest that supplies water are specially made the keying gate, are blocked the usefulness of dirt and maintenance, and the major-minor hoisting mechanism is contained in the bottom of frame, is convenient to overhaul of the equipments, maintenance, and has improved the security and stability of complete machine; Secondary crane carriage is located on the cantilever, and during its lifting, center of gravity just drops on a side of frame, and stability is better protected guarantee; This machine also has from heavy and light, characteristics that wheel load is little.
