Trolley pulley mechanism capable of automatically braking according to moving speed

Abstract

The invention relates to the technical field of brake parts, and discloses a trolley pulley mechanism capable of automatically braking according to the moving speed. The trolley pulley mechanism capable of automatically braking according to the moving speed comprises a rotating shaft, a rotating wheel is movably connected in the rotating shaft, a fixed shaft is movably connected in the rotating wheel, a trigger mechanism is arranged on the front surface of the rotating shaft, and a mounting seat is arranged on the front surface of the fixed shaft. A braking mechanism is hinged to the front surface of the mounting seat, and a driving mechanism is arranged on the front surface of the fixed shaft. According to the trolley pulley mechanism capable of automatically braking according to the moving speed, through cooperative use of the rotating shaft and the trigger mechanism, when the rotating speed of trolley pulleys is too high, the braking mechanism is triggered to work. Through cooperative use of the driving mechanism and the braking mechanism, a supporting rod starts to rotate under the movement of a limiting sleeve, so that the braking effect is achieved by enabling a braking piece to make contact with the inner wall of the rotating shaft, the manual operation process is omitted, the proper transportation speed is guaranteed, and goods are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of braking components, in particular to a pulley mechanism for automatic braking according to moving speed for a trolley. Background technique [0002] Braking refers to the action of stopping or reducing the speed of running locomotives, vehicles and other means of transport or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install a corresponding brake shoe, belt or disc on the machine base, and make it generate braking torque under the action of external force. In order to make the moving objects controllable, it is necessary to set up a braking system on the pulley. In logistics transportation, it is also installed on common trolleys, but the braking system of logistics trolleys is basically manually operated. Not only can it not guarantee a suitable transportation speed, but also the braking effect may be poor due to operator error, which a...
