Description
Technical field
The present invention relates to a kind of high-rise rescue elevator machine of non-twined formula, the specifically high-rise rescue elevator machine of non-twined formula
Checking brake.
Background technology
The U of CN 202785175 disclose the deceleration damping unit of the high-rise rescue elevator machine of non-twined formula, be specifically (referring to
Its Figure of description 11-13)：Deceleration damping unit 25 includes speed changer 26（Reductor）With loadwheel 27, loadwheel is arranged on
Put outside bearing 263 on the output shaft 261 of the reductor；The peripheral band of loadwheel axially takes turns eaves 271, and loadwheel also includes,
The center of circle of two fan-shaped friction plates 272 overlaps staggered relatively be arranged on and rubbed on bar 274, and by two extension springs 273 up and down
Connection；The outline of friction bar is just filled up in the space formed between two fan-shaped friction plates, and friction bar key connects
It is connected on speed reducer output shaft, there is gap two fan-shaped friction plate outward flanges with wheel eaves；The key of input shaft 262 connection of reductor
Input gear 28, input gear is engaged with the connection gear 30 on main shaft 29.When main shaft rotary speed be cage descending speed just
Chang Shi, friction bar and two friction plate rotating speeds are normal, and two friction plates are in the presence of tension spring tension, and two friction plates are stuck in
Rub on bar, now loadwheel remains stationary on bearing block；When main shaft rotary speed is cage descending excessive velocities, rub
Pad seat and two fan-shaped friction plate rotating speeds are improved therewith, and two fan-shaped friction plates overcome extension spring under the influence of centrifugal force
Pulling force shift to wheel eaves, with wheel eaves friction, drive loadwheel add rotation, increase the load of system, limit output shaft turn
The rising of speed, and then limit the rotating speed of main shaft and persistently rise, rotating speed is lowered.It can be seen that, it is without braking function, it is necessary to another
Brake is set, and this can cause huge structure, numerous and diverse, the feasibility of reduction whole system.If by loadwheel be designed to it is static not
Dynamic, although braking function can be increased, but when two fan-shaped friction plates rub with fixed loadwheel wheel eaves, can make and rub
Pad and loadwheel heat, until smoldering, can not only damage friction plate, burning can be produced when serious, potential safety hazard is left.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of gear of the high-rise rescue elevator machine of non-twined formula
Pump self-cooled checking brake.
The object of the present invention is achieved like this：It includes rotation assembly, the rotation assembly refer to above and below two extension springs connect
The two fan-shaped friction plates connect are arranged on friction bar, and friction bar key is connected on speed reducer output shaft, it is characterized in that：
It also includes static assembly and coolant self-circulation system；
Static assembly includes, and reductor flange is connected on reductor casing, the outer end connection circle of reductor flange axis hole
Box-like annular seal space, reductor flange axis hole sets bearing, and speed reducer output shaft enters round box shape annular seal space through the bearing inner sleeve
In, rotation assembly is arranged in round box shape annular seal space；The fan-shaped friction plate of two of rotation assembly and round box shape annular seal space cavity wall
Distance is that two fan-shaped friction plates and round box shape annular seal space cavity wall formation gap, work as extension spring when extension spring is not by centrifugal action
Contacted by two during centrifugal action fan-shaped friction plates with round box shape annular seal space cavity wall；The periphery of round box shape annular seal space cavity wall sets one
Water annulus is enclosed, a water inlet and a delivery port are set on water annulus；
Coolant self-circulation system is that hydraulic gear pump and its flange are arranged on round box shape annular seal space outer face, hydraulic pressure tooth
The axis hole of the keyed gear shaft of wheel pump through gear pump flange enters in annular seal space, and speed reducer output shaft outer face is inwardly formed blind
Hole and keyway, make gear shaft be inserted into blind hole, and key enters keyway, forms two axle key attachment structures, the import of hydraulic gear pump
It is docked at the delivery port and water inlet set on water annulus respectively with outlet.
When the cage descending speed of the high-rise rescue elevator machine of non-twined formula is that speed reducer output shaft rotating speed is normal, friction plate
Seat and two friction plate rotating speeds are normal, and two friction plates are in the presence of tension spring tension, and two friction plates are stuck on friction bar,
Now extension spring is not by centrifugal action, two fan-shaped friction plates and round box shape annular seal space cavity wall formation gap, checking brake
Do not work；When cage descending speed is that speed reducer output shaft rotating speed is too fast, friction bar and two fan-shaped friction plates turn
Speed is improved therewith, and two fan-shaped friction plates overcome the elastic force of extension spring to be outwardly towards round box shape annular seal space under the influence of centrifugal force
Cavity wall, with cavity wall friction, limits the rotating speed of output shaft until braking；At the same time the eccentric wheel speed of plunger type water pump increases
Plus, plunger type water pump work, the coolant of driving water annulus is circulated, by cavity wall because the heat that friction is produced is taken away.
Compared with prior art, the positive effect of the present invention is：It is integrated in one slowing down with braking function, reduces machine
Structure, reduces cost, improves the reliability of system；Simultaneously to slow down and brake setting cooling device, potential safety hazard is eliminated.
