Abstract

The invention relates to an automatic braking mechanism. The automatic braking mechanism is characterized in that the automatic braking mechanism comprises an outer locking mechanism (1), an inner locking mechanism (2), elastic elements (3) and a friction pair (4) which are sequentially mounted on the same axis; the position of the outer locking mechanism (1) is limited in the axial direction, andthe inner locking mechanism (2) can move in the axial direction; the outer locking mechanism (1) comprises outer locking wedge blocks (1-2) and a disc-shaped first base body (1-1), and the outer locking wedge blocks (1-2) are fixed to the plane of the inner side end face of the base body (1-1); the inner locking mechanism (2) comprises inner locking wedge blocks (2-2) and a disc-shaped second base body (2-1), the inner locking wedge blocks (2-2) are fixed to the plane of the outer side end face of the second base body (2-1), and the outer locking wedge blocks (1-2) and the inner locking wedgeblocks (2-2) are matched; and when the outer locking mechanism (1) and the inner locking mechanism (2) rotate relatively, the outer locking wedge blocks (1-2) and the inner locking wedge blocks (2-2)are matched to achieve two working states.

Description

technical field [0001] The invention belongs to the field of hoisting equipment brakes, and relates to an automatic braking mechanism with compact structure, sensitive braking, reliable operation and small impact. Background technique [0002] At present, the braking mechanisms used on lifting equipment are divided into block type, belt type and disc type. Usually electromagnetic or hydraulic forms are used to apply positive pressure to the brake friction pair to generate braking torque to achieve the purpose of braking. When braking, the brake must be locked first, and the brake must be released first during normal operation. The braking mechanism has a slow response speed, poor braking sensitivity and reliability, and the structure is not compact enough. There is a shock to the system when the brake is applied and released, and when the weight is lowered. Contents of the invention [0003] The purpose of the present invention is to provide a lifting device with a compa...
