Description

Swinging device of industrial fan

Technical Field

The utility model belongs to the technical field of industrial products, a device that sways of industrial fan is related to.

Background

In order to provide wider coverage, fans can be provided with swinging capacity, in the prior art, a left swinging head and a right swinging head of the fan generally have two structures, the first structure is that a worm on a rotor shaft is meshed with a matched turbine, the turbine is provided with an eccentric shaft, the eccentric shaft drives a connecting rod to move back and forth to drive the fan head to swing left and right, the second structure is that the fan swinging head is driven by a synchronous motor, the rotating direction of the synchronous motor is random, the rotating direction can be automatically changed after resistance is applied, and the synchronous motor is prevented from rotating when the swinging head swings to a set position, so that the phenomenon of reciprocating swinging head is formed.

However, the above two types of structures are adopted, or a synchronous motor is adopted, so that the cost is increased, or a turbine worm is used for generating a phenomenon of blocking in a long-term use, and the swing amplitude of the swing head cannot be adjusted by adopting the above two structures.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a swinging device of industrial fan to the not good problem of current industrial fan yaw mode.

The purpose of the utility model can be realized by the following technical proposal:

a swinging device of an industrial fan is characterized in that: it includes the fan head, the fixed backup pad that sets up, the connecting rod, crank and rocking motor, rotate through the primary shaft between fan head and the backup pad and be connected, the fixed setting of rocking motor is in the backup pad, articulate one end fixed connection is at rocking motor's main shaft tip, the articulate other end passes through the secondary shaft with the one end of connecting rod and rotates and be connected, the other end of connecting rod rotates through the third shaft and is connected with the fan head, the virtual line segment that primary shaft and third shaft formed, the connecting rod, form the crank rocker structure between the rocker three, the connecting rod includes outer pole and interior pole, the slide opening has been seted up on the outer pole, interior pole slides and sets up in the slide opening, the third shaft is in the one end tip of outer pole inside rod dorsad, the second shaft is in the one end tip of outside pole.

In the above swing device for an industrial fan, a gap is formed between the support plate and the fan head, a fixing hole is formed in the support plate, the swing motor is fixedly arranged in the fixing hole, and the connecting rod, the crank and the spindle of the swing motor are located in the gap.

Compared with the prior art, the swinging device adopts a simple and long-service-life structural principle, and can adjust the swinging amplitude of the fan head.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the swing device of the industrial fan comprises a fan head 1, a support plate 2, a connecting rod 3, a crank 4 and a swing motor 5, wherein the fan head 1 and the support plate 2 are fixedly arranged, the swing motor 5 is fixedly arranged on the support plate 2, one end of the crank 4 is fixedly connected with the end part of a main shaft of the swing motor 5, the other end of the crank 4 is rotatably connected with one end of the connecting rod 3 through a second shaft, the other end of the connecting rod 3 is rotatably connected with the fan head 1 through a third shaft, a crank 4 rocker structure is formed among a virtual line segment formed by the first shaft and the third shaft, the connecting rod 3 and the rocker, the connecting rod 3 comprises an outer rod 6 and an inner rod 7, a sliding hole is formed on the outer rod 6, the inner rod 7 is slidably arranged in the sliding hole, the third shaft is arranged at the end part of the outer rod 6 opposite to the inner rod 7, the second shaft is, the side of the outer rod 6 is provided with a locking stud 8.

The rocking device adopts the crank 4 rocker principle in mechanics, after rocking motor 5 continuously rotates, crank 4 can rotate periodically, then drive a fan head 1 through connecting rod 3 and swing, and, the length of connecting rod 3 can change, as long as loosen locking stud 8, interior pole 7 just can slide for outer pole 6, after sliding to suitable position, lock locking stud 8 can, this process main objective is the length that changes connecting rod 3, after the length change of connecting rod 3, the range of fan head 1 beat in-process also can produce the change.

Have the gap between backup pad 2 and the fan head 1, seted up a fixed orifices on the backup pad 2, the fixed setting in the fixed orifices of swing motor 5, connecting rod 3, crank 4 and swing motor 5's main shaft are in the gap, adopt this structure, can be at utmost save space, arrange the position of each spare part in reasonable position.

It is to be understood that in the claims, the specification of the present invention, all "including … …" are to be interpreted in an open-ended manner, i.e. in a manner equivalent to "including at least … …", and not in a closed manner, i.e. in a manner not to be interpreted as "including … … only".
