The human body accelerating equipment is designed with the functions of power-off braking and emergency braking, and the brake 5 can brake the winding drum 4 at a certain acceleration when the motor 1 is powered off or the emergency stop button is manually pressed. The power-off braking device ensures that the motor decelerates and brakes under emergency conditions such as power failure and the like, and ensures the safety of users.
The winding displacement mechanism 6 of the human body accelerating equipment of the invention consists of a roller 10, a spring 11 and a bearing. The roller 10 is made of nylon material and is connected with the shaft through a bearing. The spring 11 pulls the connecting rod control roller against the drum. The requirement of multilayer self-adaptive reciprocating wire arrangement is met by ensuring that the pressing force of the roller is approximately equal to the pulling force of the spring, and stable wire collection can be ensured in the acceleration process, the deceleration process and after rope throwing.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
