Description
Technical field
The present invention's wheeled track fee engine clutch device and supporting friction braking safety belong to rail mounted vertical or inclined lift field of transport machinery, particularly building hoist and elevator car safety.
Background technology
Building hoist and elevator are the vertical transportation machineries that is widely used in construction site and the high-rise, and its safety plays crucial effects to people's safety of life and property.Therefore, the safety of constantly improving the vertical lift Transport Machinery is the target of insider's unremitting pursue.Though the synchronous self locking safety of Chinese utility model patent pincers (CN 200420017782.1) have solved this outstanding problem of falling suddenly that reasons such as building hoist cage invar silk fracture of rope cause reliablely, but still fail to separate the cage overspeed accident problem that other reason that disconnected by no means rope falls causes.The existing hypervelocity safety catch of elevator is top or the bottom that the hypervelocity control setup is arranged on elevator at present, the braking device for carrying out said is arranged on the guide rail, connect by steel rope between the two, for this mechanism, because the steel rope trip path is long, in case during elevator load-carrying accident hypervelocity, hypervelocity control and enforcement are braked and can not be carried out synchronously, cause braking retardation.Moreover, the steel rope between hypervelocity control and enforcement braking two parts, under the high tension of glancing impact, steel rope has the potential danger of fracture.In addition, this class hypervelocity safety catch can not be resisted the bad working environments of outdoor study, often early failure.
Therefore, the overspeed safety arrestment protection of vertical lift machinery, the key subjects that this relates to people's safety of life and property remain insider's innovative development.
Summary of the invention
The purpose of this invention is to provide a kind of wheeled track fee engine clutch device and supporting friction braking safety, its fee engine clutch device and supporting friction brake, be installed on the same operation guide rail, to the running hypervelocity that elevator causes for some reason, can the synchronization implementation braking.The centnifugal force axial component of centnifugal force member that the wheeled track fee engine clutch overspeed rotation of broad applicability is promptly arranged with the present invention forms driving torque output, passes to sure brake synchronously, and the synchronization implementation safety arrestment.Thereby the hypervelocity that solves the existence of current this area is controlled and is implemented braking and splits installation, and it is asynchronous with the enforcement braking that hypervelocity is controlled, and braking is the unsafe problems of hysteresis obviously.
Another object of the present invention provides a kind of and the friction braking safety wheeled fee engine clutch matched with devices of the present invention, is symmetrical in two tilting friction framework wedges of guide rail with it and implements effectively braking.
The objective of the invention is to be achieved through the following technical solutions:
The present invention is a kind of overspeed safety catch, is made up of hypervelocity control setup and supporting braking device for carrying out said two parts thereof.This hypervelocity control setup is wheeled track fee engine clutch device, and supporting braking device for carrying out said is a wedge type friction braking safety.Friction braking safety of the present invention is fixedly connected on elevator craning cage or the elevator cage, elevator or cage guide are placed in one, wheeled track fee engine clutch is arranged on guide rail one side, keep well contacting with guide rail by bindiny mechanism, and be connected with the friction braking safety by the fixed support plate.Therefore, the hypervelocity control setup of the overspeed safety catch of the design and supporting braking device for carrying out said all are arranged on the guide rail of elevator craning cage or elevator cage operation, supporting compactness, so can work as elevator craning cage or elevator cage hypervelocity the time, synchronization implementation safety arrestment immediately.Really avoid because of elevator craning cage or elevator cage out of control, the contingency that overspeed causes on guide rail.
Now the present invention's wheeled track fee engine clutch device and supporting friction braking safety are summarized as follows:
