A brake with a speed-limiting function

Abstract

The invention discloses a brake with a speed limiting function, which includes a drum brake and a brake driving mechanism; The drive block and the elastic element arranged between the brake drive block and the brake drum; when the speed of the brake drum is lower than the set value, the elastic force of the elastic element always promotes the outer end of the brake drive block to be positioned at the brake On the inner side of the boundary circle, when the rotational speed of the brake drum is higher than the set value, the brake drive block moves outward in the radial direction against the elastic force of the elastic element under the action of centrifugal force, and the outer end of the brake drive block protrudes Brake the boundary circle and touch the drive frame. The invention can automatically brake and reduce the speed when the monorail conveyor is running at overspeed, so as to ensure the safe operation of the monorail conveyor; when the running speed of the monorail conveyor is too fast, the braking drive is realized by increasing the centrifugal force on the braking drive block, Clever design.

Description

technical field [0001] The invention relates to a monorail conveyor, in particular to a brake with a speed limiting function. Background technique [0002] The terrain conditions of mountain orchards are mostly mountains or hills, so the mechanized production level of mountain orchards is not high. In order to reduce labor intensity, production cost and improve orchard production efficiency, the use of unmanned monorail transport equipment for agricultural materials or fruit transportation has become the main trend of the development of the fruit industry in mountainous areas. The unmanned monorail transporter is a modern machine that can not only overcome the geographical environment of steep mountains and slopes, but also complete the transportation by itself in dense fruit tree orchards. [0003] Unmanned monorail conveyors are generally equipped with devices such as speed limiters, overrunning clutches and parking brakes, which can limit the running speed of the conveyo...

AI Technical Summary

Problems solved by technology

[0003] Unmanned monorail conveyors are generally equipped with devices such as speed limiters, overrunning clutches and parking brakes, which can limit the running speed of the conveyor and avoid overspeeding of the conveyor; Large vibration, so the above-mentioned speed limiter and other devices are prone to malfunction, resulting in overspeed operation of the monorail transport plane, resulting in derailment of the transport plane, leading to accidents

At present, most of the manned monorail conveyors are equipped with drum brakes, so that when the speed of the monorail conveyor is too fast, the brake cam can be manually controlled to open the two brake shoes and make contact with the brake drum, thereby realizing braking. However, there are no drum brakes that can automatically reduce the speed when overspeeding in unmanned monorail transport aircraft.
