Description

Technical Field

[0002] Centrifugal fans are machines that rely on input mechanical energy to increase gas pressure and discharge gas. They are a type of driven fluid machine. Centrifugal fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling.

[0003] The dynamic balance of the impeller of the air cooler directly affects the vibration and noise values. When the impeller is out of balance, the impeller may be seriously worn after working for a period of time, causing the fan rotor to be unbalanced, thereby increasing the amplitude of the entire fan, seriously affecting the normal operation of the main equipment. Therefore, in actual work, it is necessary to perform dynamic balance tests on centrifugal fans to eliminate the imbalance factors in time so that the main equipment can maintain a good operating state. When using existing equipment to perform dynamic balance detection on the fan impeller, due to the high-speed rotation of the impeller, if someone accidentally touches it, it is easy to injure people.

[0004] Therefore, it is necessary to provide a centrifugal air cooler detection device with a protective function. Utility Model Content

The first connecting rod 14 is rotatably arranged in the mounting shell 13, and the first connecting rod 14 penetrates to the outside of the mounting shell 13.

Two guide seats 19 are installed on both sides of the base 1 by bolt connection, and the clamping rod 20 is horizontally slidably arranged on the guide seat 19, and the clamping rod 20 can be clamped with the clamping block 1501. The side of the support frame 401 away from the console 2 is rotatably arranged with two rotating rods 17, and the two rotating rods 17 are respectively provided with the first pulley group 16 on the two first connecting rods 14.

[0025] See also Figure 2 and Figure 3 As shown, the clamping assembly includes a first guide rod 6 fixedly connected to the base 1 by welding, a movable plate 4 is horizontally slidably arranged on the first guide rod 6, an adjusting screw 5 is rotatably arranged on the base 1, the movable plate 4 is threadedly connected to the adjusting screw 5, the movable plate 4 is located in the middle of the support frame 401, and mounting plates 7 are rotatably arranged on the movable plate 4 and the support frame 401, the two mounting plates 7 are symmetrically distributed, the mounting plate 7 on the support frame 401 is fixedly connected to the rotating shaft 11 by a key, and the two mounting plates 7 are fixedly connected with upper and lower second guide rods 8 by welding, and a clamping plate 9 for clamping and fixing the impeller shaft is slidably arranged on the two second guide rods 8 on the same mounting plate 7, a bidirectional screw 10 is rotatably arranged on the mounting plate 7, and the two clamping plates 9 are threadedly connected to the bidirectional screw 10.

[0026] When it is necessary to perform dynamic balancing test on the impeller of the centrifugal air cooler, the impeller shaft is placed between the mounting plates 7 on both sides, and the adjusting screw 5 is turned to make the movable plate 4 slide along the first guide rod 6 to the side away from or close to the control console 2, so that the distance between the two mounting plates 7 fits the size of the impeller. Then, the impeller shaft is placed between the two clamping plates 9 on both sides, and the two clamping plates 9 are driven to slide close to each other along the second guide rod 8 by turning the bidirectional screw 10, so that the two clamping plates 9 clamp the impeller shaft together, and then the first motor 3 is started to drive the rotating shaft 11 to rotate, so that the rotating shaft 11 drives the mounting plate 7 to rotate on the support frame 401, thereby making the impeller rotate at high speed. At this time, the mounting plate 7 on the other side The mounting plate 7 rotates synchronously with the impeller on the moving plate 4. A counterweight is added to the impeller to continuously adjust the dynamic smoothness of the impeller. After the counterweight is installed, the installation position is recorded by the dial 12 so that the counterweight can be removed later. In order to prevent someone from touching the high-speed rotating impeller and getting injured, the two rotating rods 17 are rotated, and the first connecting rod 14 is rotated synchronously in the mounting shell 13 through the first pulley set 16, so that the first connecting rod 14 lowers the rolling curtain 15, and the clamping rod 20 passes through the guide seat 19 and the clamping block 1501 at the bottom of the rolling curtain 15, so that the rolling curtain 15 is fixed and will not swing, and the impeller is isolated by the rolling curtain 15 to prevent someone from accidentally touching the high-speed rotating impeller.

[0028] Since the impeller rotates at a high speed, the centrifugal force generated by it can easily cause the base 1 to vibrate, affecting the dynamic balance detection data of the impeller. At this time, the second motor 21 is started to drive the second connecting rod 22 to rotate, and the second pulley set 23 is used to drive another second connecting rod 22 to rotate synchronously, so that the second connecting rod 22 drives the screw 24 to rotate and penetrate the base 1 and drill into the ground.
