Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

As shown in fig. 1-3, a tower crane rotation vane motor and vane brake structure comprises a motor 1 and a vane brake 2, wherein the motor 1 is arranged below the vane brake 2, the motor 1 comprises a base, a front cover and a rear cover which are arranged at two ends of the base, a junction box is arranged outside the base, a stator component is arranged in the base, a main shaft is further arranged in the base, and a rotor which is sleeved on the main shaft is further arranged. The tail end of a main shaft of the motor 1 is hexagonal and is used for turning in maintenance. A plurality of wire outlet holes are formed in a rear end cover of the motor 1, and leading-out wires of the wind vane brake 2 and microswitch signal wires can conveniently penetrate out of the wire outlet holes.

The main shaft of the motor 1 is sleeved with fan blades 3 for cooling the motor 1, and a shell 7 is sleeved outside the fan blades 3. The main shaft of the motor 1 is connected with a gear sleeve 4 of the wind vane brake 2 above the fan blades 3, the tail end of the main shaft of the motor 1 is provided with an encoder 5 above the wind vane brake 2, and the encoder 5 is arranged on a magnetic yoke 6 of the wind vane brake 2 through a screw.

The wind vane brake 2 comprises a magnetic yoke, an armature arranged below the magnetic yoke and a brake disc arranged below the armature, a release plate, a micro switch and a wind vane electromagnet are further installed on the magnetic yoke, a gear sleeve 4 is meshed with the brake disc, a wind vane cover 8 is sleeved outside the wind vane brake 2, and a release handle and a wind vane push handle are arranged on the wind vane cover 8. When manual release is needed due to reasons such as power failure, the release handle can be manually lifted upwards, and then the vane push handle is pushed, so that the release support plate supports the release plate, and the motor can also rotate freely. The sealing ring is also used on the release handle and the vane push handle to play a role of water resistance.

When an operator goes off duty, the weather vane brake 2 can be firstly attracted, then the weather vane electromagnet is attracted, the electromagnet releases the supporting plate to move inwards, the weather vane brake 2 is disconnected after the electromagnet is completed, the releasing plate is supported by the releasing supporting plate, the armature is separated from the brake disc, the motor can rotate freely, and after the operator goes off duty, the tower crane windward side is prevented from being too large, and the tower crane is blown down.
