Braking device for fan rotating equipment

Abstract

A braking device for a fan rotating equipment mainly includes: a first manual brake mechanism located on the outside of the fan casing, consisting of a first support frame, a screw, and a scissor-type telescopic moving assembly, to drive two arc-shaped brake pads to clamp or release the motor output shaft; and a second manual brake mechanism located on the inside of the fan casing, consisting of a second support frame, two screws, and a linear counter-pressure moving assembly, to drive two arc-shaped brake pads to clamp or release the motor drive shaft. Both can be used individually or in combination to form a double locking system. The overall structure is simple, quick to install, and easy to operate, suitable for temporary maintenance or power outage environments. It provides a reliable manual brake mechanism to reduce risks during maintenance or inspection, preventing accidental rotation of the motor output shaft or drive shaft, effectively ensuring personnel safety and extending equipment life.

Claims

1. A braking device for a fan rotation device, mainly comprising: A first manual brake mechanism is mounted on a motor on the outside of the blower body. It has a first adjustable brake part on a first support frame and is driven by at least one screw to clamp or release two arc-shaped brake pads of a scissor-type telescopic moving assembly.

2. The braking device of the fan rotating equipment as described in claim 1, further comprising a second manual brake mechanism, which is motorly assembled on the motor drive shaft inside the fan housing, having a second adjustable brake part on a second support frame, wherein at least two screws drive two arc-shaped brake pads that move in a straight line to clamp or release the motor drive shaft.

3. The braking device for the fan rotating equipment as described in claim 1, wherein the motor is a double-ear type, the first support frame is composed of two parallel connecting rods and a crossbar, each connecting rod has a groove at its rear fixed end for adjustment and locking onto the motor housing, and a locking hole platform at its front protruding end; each end of the crossbar has a groove at each end for adjustment and locking onto the locking hole platform of the two connecting rods, the crossbar has a long hole in the middle radially for the upper end of the screw to pass through and be fixed with a nut, and; the lower end of the screw is connected to the scissor telescopic moving assembly, which is composed of a connecting piece at the upper end, a diamond-shaped cross telescopic rod in the middle, and two clamping arms at the lower end for correspondingly setting the two arc-shaped brake pads.

4. The braking device for the fan rotating equipment as described in claim 1, wherein the motor is a single-ear type, the first support frame is composed of two straight rods and a cross upper frame, each of the straight rods has a clamping slot at its lower fixed end for adjustment and locking onto the motor base, and a groove at its upper protruding end for fixing the two ends of the cross upper frame's cross rods to a high-low position lock, a straight rod with a groove is locked in the middle of the cross rod, and an axially extended hole is provided on the protruding end in front of the straight rod for the upper end of the screw to pass through and be fixed with a nut; and; the scissor telescopic moving assembly is connected to the lower end of the screw, which is composed of a connecting piece at the upper end, a diamond-shaped cross telescopic rod connected in the middle, and two clamping arms at the lower end for correspondingly setting the two arc-shaped brake pads.

5. The braking device for the fan rotating equipment as described in claim 2, wherein the second support frame is composed of a combined base and a grid frame, the grid frame is composed of two straight rods and two cross rods with interlocking grooves, the fixed ends of the two straight rods are fixedly mounted on the side of the combined base, each end of the two cross rods is provided with a connecting hole for the two screws to pass through and be fixed with two nuts to drive the linear counter-pressure moving assembly, which is composed of the middle section of the two cross rods for the corresponding placement of the two arc-shaped brake pads.

6. The braking device of the fan rotating equipment as described in claim 1 or 2, wherein the arc-shaped brake pads are provided with a connecting hole at the rear and covered with a high coefficient of friction material, selected from rubber, polyurethane or composite material, to improve the braking effect and avoid damage to the motor drive shaft; and the screws are provided with precision threads to provide a fine-tuning function to precisely control the opening and closing distance of the arc-shaped brake pads.
