Problems solved by technology
It can be seen that it does not have a braking function, and additional brakes are required, which will result in a large and complicated structure and reduce the feasibility of the entire system
If the load wheel is designed to be stationary, although the braking function can be increased, when the two fan-shaped friction plates rub against the fixed load wheel eaves, heat will be generated between the friction plate and the load wheel until smoke is emitted. , will not only damage the friction plate, but also burn in severe cases, leaving a safety hazard

The invention provides a plunger pump self-cooled retarding braking device of a non-winding high-rise rescue elevator. The plunger pump self-cooled retarding braking device is characterized by comprising a rotary assembly, a static assembly and a cooling liquid self-circulation system; according to the static assembly, the outer end of a flange shaft hole of a speed reducer is connected with a round-box-shaped sealing cavity, and a speed reducer output shaft penetrates through a bearing lining of the shaft hole to enter the round-box-shaped sealing cavity; the rotary assembly is installed in the round-box-shaped sealing cavity, and an annular water channel is arranged on the periphery of the wall of the round-box-shaped sealing cavity; and an eccentric wheel of a plunger type water pump of the cooling liquid self-circulation system is in key connection with the speed reducer output shaft, and the plunger type water pump drives self-circulation of cooling liquid in the annular water channel. The plunger pump self-cooled retarding braking device has the beneficial effects that the deceleration function and the braking effect are integrated, so that the mechanism number is reduced, and system reliability is improved; and the cooling device is arranged for deceleration and braking, and therefore potential safety hazards are eliminated.
Description
technical field [0001] The invention relates to a non-winding high-rise rescue elevator, in particular to a deceleration and braking device for the non-winding high-rise rescue elevator. Background technique [0002] CN 202785175 U discloses a deceleration damping device of a non-winding high-rise rescue elevator, specifically (see accompanying drawings 11-13 of the description): the deceleration damping device 25 includes a transmission 26 (reducer) and a load wheel 27, and the load wheel is installed on the The bearing 263 on the output shaft 261 of the speed reducer is overcoated; the periphery of the load wheel has an axial wheel eaves 271, and the load wheel also includes two fan-shaped friction plates 272 whose circle centers coincide and are installed on the friction plate seat 274, and It is connected by two tension springs 273 up and down; the outer contour of the friction disc seat just fills the space formed between the two fan-shaped friction discs. There is a g...
