Abstract

The invention discloses a crane brake device, which comprises a brake wheel arranged coaxially with the crane wheel and a brake assembly that can move to the central axis of the brake wheel during braking. The brake shaft with the central axis of the moving wheel is collinear, the brake arcs are uniformly distributed around the brake shaft through springs, the rotatable brake steel block is located at one end of the brake shaft, and one end is connected to the brake arc and the other end is infinitely close to or When braking, the brake assembly moves to the center axis of the brake wheel, the brake steel block rotates, the side of the brake steel block resists and pushes the support rod, and the support rod drives the brake arc The disc presses against the brake wheel to generate friction to prevent the rotation of the crane wheel. The invention utilizes the combination of multiple brake arcs to fit the inner side of the brake wheel, maximizing the increase of the friction area and enhancing the braking effect.

Description

technical field [0001] The invention relates to a brake device, in particular to a crane brake device. Background technique [0002] Cranes are important equipment in industrial production. They have the characteristics of large volume, heavy weight and high operating speed. The effective stop brake of the crane is conducive to production safety. Traditional crane brakes mainly include iron shoe brakes and rail clamp brakes. The iron shoe brake is to place the iron shoes on the track, and use the crane wheel to climb the slope and change the rolling to slide to play a braking role; the rail clamp is placed on the track to make the crane wheel connect with the track when braking. And then play a braking role. The above method needs to place the braking device in a specific braking area, which cannot meet the requirement of braking anytime and anywhere. [0003] Therefore, urgently need to solve the above-mentioned problem. Contents of the invention [0004] Purpose of t...
