Description
Technical field
The utility model relates to the high-rise rescue elevator machine of a kind of non-twined formula, is the checking brake of the high-rise rescue elevator machine of non-wound form specifically.
Background technology
CN202785175U discloses the deceleration damping arrangement of the high-rise rescue elevator machine of non-twined formula, specifically (see its Figure of description 11-13): deceleration damping arrangement 25 comprises change-speed box 26(reductor) and loadwheel 27, loadwheel is arranged on outside the bearing 263 on the output shaft 261 of this reductor and puts; The peripheral band of loadwheel is wheel eaves 271 axially, and loadwheel also comprises, and the center of circle of two fan-shaped friction linings 272 overlaps staggered relatively being arranged on friction bar 274, and is connected by upper and lower two extension springs 273; The outline of friction bar is just in time filled up in the space that formed between two fan-shaped friction linings, and friction bar key is connected on speed reducer output shaft, and two fan-shaped friction lining outward flanges have gap with wheel eaves; Input shaft 262 key of reductor connects input gear 28, and input gear engages with the connection gear 30 on main shaft 29.When main shaft rotative speed and cage descending speed normal time, friction bar and two friction lining rotating speeds normal, two friction linings are under the effect of tension spring tension, and two friction linings are stuck on friction bar, and now loadwheel keeps static on bearing seat; When main shaft rotative speed and cage descending excessive velocities, friction bar and two fan-shaped friction lining rotating speeds improve thereupon, the pulling force that two fan-shaped friction linings overcome extension spring under the influence of centrifugal force shifts to wheel eaves, with the friction of wheel eaves, drive loadwheel to add rotation, increase the load of system, limit the rising of output shaft rotating speed, and then the rotating speed limiting main shaft continues to rise, and is lowered by rotating speed.Visible, it is band brake function not, needs separately to arrange drg, and this can cause huge structure, numerous and diverse, reduces the feasibility of whole system.If loadwheel is designed to actionless, although can braking function be increased, when two fan-shaped friction linings and fixing loadwheel take turns eaves rub time, can make and friction lining and loadwheel heat-dissipating, until smolder, not only can damage friction lining, can burning be produced time serious, leave potential safety hazard.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide the plunger pump self-cooled checking brake of the high-rise rescue elevator machine of a kind of non-twined formula.
The purpose of this utility model is achieved in that it comprises rotation assembly, the fan-shaped friction lining of this rotation assembly two of referring to that upper and lower two extension springs connect is arranged on friction bar, friction bar key is connected on speed reducer output shaft, it is characterized in that: further comprising static assembly and refrigerant fluid self-circulation system;
Static assembly comprises, reductor Flange joint is on reductor casing, and the outer end of reductor flange axis hole connects round box shape annular seal space, and reductor flange axis hole arranges bearing, speed reducer output shaft enters in round box shape annular seal space through this bearing inner sleeve, rotates assembly and is arranged in round box shape annular seal space; Rotation two fan-shaped friction linings of assembly and the distance of round box shape annular seal space chamber wall are, when extension spring does not form gap, when extension spring contacts with round box shape annular seal space chamber wall by two fan-shaped friction linings during centrifugal action by two fan-shaped friction linings during centrifugal action and round box shape annular seal space chamber wall; A circle water annulus is established in the periphery of round box shape annular seal space chamber wall, and water annulus arranges a water inlet and a water outlet;
Refrigerant fluid self-circulation system comprises plunger type water pump, and the eccentric wheel key of plunger type water pump is connected to speed reducer output shaft, and import and the outlet of plunger type water pump set out the mouth of a river and water outlet to being connected on respectively on water annulus.
When the cage descending speed of non-twined formula high-rise rescue elevator machine and speed reducer output shaft rotating speed normal time, friction bar and two friction lining rotating speeds normal, two friction linings are under the effect of tension spring tension, two friction linings are stuck on friction bar, now extension spring is not by centrifugal action, two fan-shaped friction linings and round box shape annular seal space chamber wall form gap, and checking brake is inoperative; When cage descending speed and speed reducer output shaft rotating speed too fast time, friction bar and two fan-shaped friction lining rotating speeds improve thereupon, the elastic force that two fan-shaped friction linings overcome extension spring under the influence of centrifugal force outwards shifts to round box shape annular seal space chamber wall, with chamber wall friction, limit the rotating speed of output shaft until braking; Meanwhile the eccentric wheel rotating speed of plunger type water pump increases, plunger type water pump work, drives the cooling-liquid cycle flowing of water annulus, by chamber wall because fricative heat is taken away.
Compared with prior art, good effect of the present utility model is: deceleration and braking function are integrated in one, decrease mechanism, reduce cost, improves the reliability of system; Simultaneously for slowing down and brake setting cooling mechanism, eliminate potential safety hazard.
