Description

Technical Field

[0001] This utility model relates to the field of industrial fan technology, and in particular to an industrial fan with a braking structure. Background Technology

[0002] Industrial fans, as industrial equipment in the field of ventilation, are currently fixed to the ceiling of factories and are mainly used for cooling the area.

[0003] Existing industrial fans, even after being shut down, will continue to rotate for a period of time due to their own inertia. In the event of a fire, even after the fan is shut down for fire safety reasons, the fan blades will continue to rotate due to their own inertia, which may cause broken blades to swing around and endanger personnel safety. Therefore, in view of the above situation, there is an urgent need to develop an industrial fan with an emergency braking function that can quickly stop in dangerous situations, and has a braking structure to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide an industrial fan with a braking structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An industrial fan with a braking structure includes a hanging frame, a housing, a retaining ring, a braking mechanism, a connecting rod, and an inner disc. The connecting rod is inserted into the hanging frame and fixed thereto by a bolt assembly. The bottom of the connecting rod is fixed to the inner disc. The housing is rotatably connected to the outside of the inner disc. Multiple fan blades are fixed on the housing. The retaining ring is fixed to the upper side of the housing. The braking mechanism is located inside the retaining ring. The braking mechanism includes a drive motor, gears, a brake disc, a toothed groove, a base plate, brake pads, a slider, a guide rail, a guide rod, a limit rod, and two brackets. The drive motor is fixed between two brackets and is fixed to the hanging frame. The brake disc is rotatably connected to the outside of the connecting rod. A gear is fixed on the output shaft of the drive motor. The upper end of the brake disc is provided with a tooth groove that meshes with the gear. There are three brake pads. A slider is fixed to the bottom of each brake disc. Each slider is slidably mounted on a guide rail. The guide rail is fixed to the base plate. The base plate is fixed to the inner disc. A guide rod that penetrates the brake disc is fixed to each brake pad. Three limiting rods that penetrate the brake disc are evenly distributed and fixed on the base plate.

[0007] Preferably, the three brake pads are evenly distributed in a circle with the central axis of the brake disc as the reference.

[0008] Preferably, the brake disc is provided with three first grooves for sliding the guide rod, and the brake disc is provided with three second grooves for sliding the limit rod.

[0009] The beneficial effects of this utility model are as follows: When the industrial fan with a braking structure is running normally, the fan motor drives the outer casing, fan blades, and retaining ring to rotate. The rotation of the fan blades generates airflow. At this time, the brake pads do not contact the inner wall of the retaining ring, thus not affecting the fan's operation. In an emergency requiring a rapid stop, the fan motor is turned off, and simultaneously, the drive motor is started, driving the gears to rotate. The gears rotate, causing the brake disc to rotate. The brake disc rotates, causing the guide rod to move in the first slide groove. The guide rod then moves the brake pads outward along the guide rail, causing the brake pads to press firmly against the inner wall of the retaining ring. The significant friction between the brake pads and the retaining ring causes the retaining ring, outer casing, and fan blades to stop quickly. In summary, this utility model has an emergency braking function, enabling rapid stopping in dangerous situations and enhancing safety. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1 to 7In this embodiment of the present invention, an industrial fan with a braking structure includes a hanging frame 1, an outer shell 2, a retaining ring 4, a braking mechanism 5, a connecting rod 6, and an inner disc 7. The hanging frame 1 is used for hanging and installing on the ceiling in the factory. The connecting rod 6 is inserted into the hanging frame 1 and fixed to it by a bolt assembly. The bottom of the connecting rod 6 is fixed to the inner disc 7. The outer shell 2 is rotatably connected to the outside of the inner disc 7. Multiple fan blades 3 are fixed on the outer shell 2. A fan motor (not shown) is fixed to the bottom of the inner disc 7 on the inner side of the outer shell 2. The fan motor output... The output shaft is fixedly connected to the outer casing 2. The fan motor drives the outer casing 2 and fan blades 3 to rotate, thus generating airflow. A retaining ring 4 is fixed to the upper side of the outer casing 2. A braking mechanism 5 is located inside the retaining ring 4. The braking mechanism 5 includes: a drive motor 501, a gear 502, a brake disc 503, a toothed groove 504, a base plate 505, a brake pad 506, a slider 507, a guide rail 508, a guide rod 509, a limit rod 510, and a bracket 511. There are two brackets 511, which are fixed to the hanging frame 1. The drive motor 501 is fixed between the two brackets 511. The brake disc 503 is rotatably connected to the outside of the connecting rod 6. A gear 502 is fixed on the output shaft of the drive motor 501. The upper end of the brake disc 503 is provided with a toothed groove 504 that meshes with the gear 502. There are three brake pads 506, which are evenly distributed in a circle with the central axis of the brake disc 503 as the reference. The brake pads 506 are used to press against the inner wall of the retaining ring 4 to achieve braking. A slider 507 is fixed to the bottom of each brake disc 503. Each slider 507 is slidably mounted on a guide rail 508. Fixed to the base plate 505, which is fixed to the inner disc 7, each brake pad 506 has a guide rod 509 that passes through the brake disc 503. The brake disc 503 has three first grooves 5031 for sliding the guide rods 509. Three limiting rods 510 that pass through the brake disc 503 are evenly distributed and fixed on the base plate 505. The brake disc 503 has three second grooves 5032 for sliding the limiting rods 510. When the fan is running normally, the brake pads 506 do not contact the inner wall of the retaining ring 4, and will not affect the operation of the fan.

[0022] Working principle: This industrial fan with a braking structure operates normally. The fan motor drives the outer casing 2, fan blades 3, and retaining ring 4 to rotate. The rotation of fan blades 3 generates airflow. At this time, the brake pads 506 do not contact the inner wall of the retaining ring 4 and do not affect the operation of the fan. In case of an emergency requiring a quick stop, the fan motor is turned off, and at the same time, the drive motor 501 is started to drive the gear 502 to rotate. The rotation of gear 502 drives the brake disc 503 to rotate, which in turn drives the guide rod 509 to move in the first slide groove 5031. The guide rod 509 drives the brake pads 506 to move outward along the guide rail 508, so that the brake pads 506 press tightly against the inner wall of the retaining ring 4. The huge friction between the brake pads 506 and the retaining ring 4 causes the retaining ring 4, outer casing 2, and fan blades 3 to stop quickly.
