Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0031] Example.

[0032] Such as figure 1 As shown, in this embodiment, the fully balanced steel wire rope hoisting type vertical ship lift includes 8 safety drums 1, 8 torque drums 3 and 4 reducers 4; 8 torque drums 3 are decelerated The device 4 and the synchronous shaft system 7 are connected in series to ensure rigid synchronization while the 4 motors 6 are synchronous; the 8 safety drums 1 are independent structures without external power drive; the main lifting system also includes 4 sets of pulley blocks 8, which are used to To bear part of the weight of the bearing box.

[0033] Such as figure 2 As shown, in this embodiment, 7 pairs of No. 1 safety brakes 2 are set on the safety reel 1, and the braking r...

Abstract

The invention relates to a safe braking method of a full-balance steel wire rope winch lifting type vertical ship lifting machine, and belongs to the field of navigation buildings of water conservancyand hydropower engineering. The full-balance steel wire rope winch lifting type vertical ship lifting machine can safely and effectively stop during normal operation shutdown and accident emergency shutdown. The method comprises a normal operation braking method and an emergency braking method of the vertical ship lifting machine, a set of pump stations are used for controlling all working brakesand safety brakes, the brake time of the plurality of sets of brakes is strictly controlled, and the phenomenon that a main lifter generates uneven loads in the starting or braking process is avoided; and under the working condition of an accident, the safety brakes are adopted for braking in a grading mode, the full-pressure brake of the working brakes is achieved after the system is effectivelystopped, it is ensured that the ship lifting machine can be safely stopped in an emergency state, the impact of the emergency braking on a transmission system and the internal stress of a main lifting system are reduced, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to a safety braking method for a fully balanced steel wire rope hoisting type vertical ship lift, which belongs to the field of navigable buildings in water conservancy and hydropower projects. Background technique [0002] A basic feature of the fully balanced wire rope hoisting vertical ship lift is that the total weight of the ship-bearing compartment is equal to the total weight of the counterweight, and the ship lift only needs to overcome the misloaded water weight, system frictional resistance, inertial force, etc. during operation. Load, so the lifting force of the main hoist is relatively small, and the energy consumption is low. It is the type that is mostly used in large ship lifts at present. The 500t-class ship lift of the Silin Hydropower Station adopts a fully balanced steel wire rope hoisting type vertical ship lift, with a lifting height of 76.7m, a total load of water in the ship-bearing compartment of 3,300t, a ...
