2results about How to "With braking function" patented technology

This utility model discloses a zipline trolley with speed measurement and braking functions, relating to the field of zipline safety technology. It includes a frame, a first wheel set, a second wheel set, an encoder, an electromagnetic brake, and a controller. The first wheel set includes two first wheels mounted on the frame, used for rotating downwards along the carrying cable. The second wheel set includes a brake wheel axle and two second wheels mounted on the frame, capable of rotation, and the second wheels fixedly mounted on the brake wheel axle, also used for rotating downwards along the carrying cable. The electromagnetic brake is fixedly mounted on the frame and mounted on the brake wheel axle, capable of braking the brake wheel axle. The encoder is fixedly mounted on the frame and can detect the rotational speed of the brake wheel axle. The controller is fixedly mounted on the frame and is communicatively connected to the encoder and the electromagnetic brake. This utility model can effectively measure and control the running speed and station entry speed of the zipline trolley.

This utility model relates to the field of speed reducer technology and discloses a traveling speed reducer, including a rear flange, an input shaft rotatably connected to the rear flange, a first-stage planetary reduction mechanism, a second-stage planetary reduction mechanism, a brake end cover, and a brake shaft rotatably connected to the brake end cover. The first-stage planetary reduction mechanism includes a first-stage sun gear, first-stage planet gears, a shaft disc, and a first-stage gear ring. The second-stage planetary reduction mechanism includes a second-stage sun gear, second-stage planet gears, a planet carrier, and a second-stage gear ring. A hub is fixedly connected to the outer side of the first-stage gear ring. This utility model is equipped with a brake shaft, which can be connected to an external brake for braking, thereby enabling the speed reducer to have a braking function. This can effectively reduce the impact during equipment start-up and shutdown, reduce component wear, extend equipment service life, and can also immediately stop the machinery in case of mechanical failure or motor malfunction, ensuring system safety and providing emergency stop capability, which can help achieve more precise motor control.
