Embodiment Construction

[0017] The present invention includes a pulley block 2 that drives the moving door 1 of the fume hood to move up and down. The pulley block 2 is driven by a synchronous rod 3 connected to it to rotate, and the synchronous rod 3 is provided with a brake disc 4 that moves with the synchronous rod 3. , the brake disc 4 is provided with a number of brake holes 41 upwards, and the position adjacent to the brake disc 4 is provided with a brake lever 5 that can penetrate into the brake holes 41 .

[0018] The brake lever 5 is driven by an electromagnetic drive mechanism 6 to move.

[0019] The brake hole 41 extends from the brake disc 4 toward the brake lever 5, the front end of the brake hole 41 is in a concave tapered shape, and the front end of the brake lever 5 is set to correspond to the brake hole 41. of the cone.

[0020] At least a part of the mating surface between the brake hole 41 and the brake lever 5 is a magnetic surface.

[0021] The corresponding brake holes 41 are ...

Abstract

The invention relates to a fume cupboard movable door braking device. The fume cupboard movable door braking device comprises a pulley set (2) driving a fume cupboard movable door (1) to move up and down. The pulley set (2) is driven by a synchronous pole (3) connected with the pulley set to rotate. A servo brake disc (4) moving along with the synchronous pole (3) is arranged on the synchronous pole (3) in a sleeving mode. A plurality of braking holes (41) are formed in the circumferential direction of the brake disc (4). Braking bars (5) capable of penetrating to the braking holes (41) are arranged in the position close to the brake disc (4). According to the fume cupboard movable door braking device, by means of matching of the braking bars and the braking holes, the rotation of the brake disc and then the rotation of the synchronous pole are stopped, and thus the rotation of the pulley set is stopped; and finally, the movable door is prevented from falling. Therefore, the operation safety of the fume cupboard movable door is improved.

Description

technical field [0001] The invention relates to a brake device for a moving door of a fume hood. Background technique [0002] The moving door of the fume hood is usually driven by a synchronous belt, wire rope, and chain. In the environment of high-strength corrosive gas, it is easy to be damaged, causing the moving door to suddenly fall during operation, causing property damage and staff injury. [0003] At present, there are no effective measures to prevent such problems in China. Contents of the invention [0004] The purpose of the present invention is to provide a brake device for the moving door of the fume hood which can prevent the moving door from falling suddenly during operation and thus ensure the safety of work. [0005] For this reason, the technical solution adopted by the present invention is: the present invention includes a pulley block (2) that drives the fume hood moving door (1) to move up and down, and the pulley block (2) is driven by the synchrono...
