Technical field
The present invention relates to a kind of transmission mechanism of building hoist, particularly relate to the two brake power unit of a kind of transmission mechanism of building hoist.
Background technology
Current transmission mechanism of building hoist generally adopts single brake power unit mode.This single brake power unit mode structurally fairly simple convenience, but there is many drawbacks:
1. safe reliability is poor.Single brake power unit only has one group of magnet stopper, when drg breaks down, whole power unit just cannot normally work: as there is release fault, then the outputting power of power unit is obstructed, and becomes running resistance and increases the reduction that mechanical load causes driving efficiency.Long-time belt brake runs, and not only increase the additional wear of these parts and aggravate to lose efficacy, and occurring difficulty in starting, electrical equipment damages, and even burns out restraining coil and even motor coil.Make transmission device cisco unity malfunction; As there is brake fault, then can not need promptly and accurately to brake or locate by control, scooter under the lighter, flat bed is forbidden to cause upper and lower material difficulty; Severe one mechanism and the hard land of cage are squatted at the end, more impact distortion and damage, and may lead to safety misadventure.
2. traditional single brake power unit mode trouble free detection and control protection.Because of the magnet stopper band gap automatic tracking compensating device of traditional single brake power unit mode, cannot the protection of config failure detection and control.
3. running comfort is poor.Operationally because the existence of starting loop and stopping deceleration/decel, with the running velocity of transmission device and the difference of live load, the impact of start-stop frequently occurs in various degree.The start/stop impact of building hoist is the wear-out failure of building hoist transmission device, aggravation failure the most direct reason frequently, larger on the traveling comfort impact of occupant.Single brake power unit is braked unicity because of it and lack technical measures flexibly and effectively in solution traveling comfort.
4. along with building hoist is to efficient energy-saving and the development subtracting this consumption reduction direction, a large amount of two drive transmission devices using two groups of power unit compositions on market, because power unit is single brake structure, when arbitrary group of generation brake fault wherein, then whole transmission device cannot safe operation in one group of power unit situation, even if outputting power can meet load needs when underloading, but demand for security cannot be met because of the list braking of single group power unit;
5. because of safe reliability requirement, traditional steel wire rope type material elevator is updated to pinion and-rack material elevator, and the generally use of the list group power unit transmission device brought, the more two brake power unit of its safe reliability brings indispensable needs.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
For solving the problem, the two brake power unit of transmission mechanism of building hoist that the invention provides a kind of safe, reliable, comfortable, smooth running and can detect, control.
