Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model discloses a motor protection device, including base 1 and the supporting seat 3 that is used for laying motor 2, the head end of supporting seat 3 is articulated through pivot 7 with base 1, and the tail end passes through spring 4 and links to each other with base 1, and when motor 2 received the overload tensile force that comes from the drive belt, spring 4's elasticity was overcome round pivot 7 to tensile force direction rotation to supporting seat 3.

In the transmission mounting mode, the motor is fixed on the base, and the motor and other electrical equipment are easily damaged because the motor cannot play a role in buffering when the tension of the belt is increased. The utility model utilizes the supporting seat 3 and the base 1 to be a movable mounting seat, when in normal state, the supporting seat 3 is fixed with the base 1 through the dead weight of the motor 2 and the tensioning action of the spring 4, and in order to ensure reliable connection, the spring 4 adopts a spring with high strength and high tensioning force; when the equipment is started or in an abnormal condition, when the output power of the motor 2 is increased, the tension of the belt pulley is increased, and the supporting seat 1 can overcome the elastic force of the spring 4 and generate certain deflection around the rotating shaft 7; when the motor 2 recovers to work normally, when the output power of the motor 2 recovers to be stable, the tension force of the belt pulley is reduced, and the supporting seat 1 recovers to a normal working position under the self-weight and the tension force of the spring 4, so that the protection of the motor 2 and electrical equipment is realized, and the electrical equipment is prevented from being damaged when the overload of the motor 2 in the production process causes overload.

In order to guarantee the stability of motor 2 under normal condition work, will supporting seat 3 designs into the bottom surface and contacts with the base, and the top surface designs into the higher, lower inclined plane of tail end of head end, and motor 2 installs the position that is close to the head end at the top surface of supporting seat 3. As shown in fig. 1, the section of the whole supporting seat 3 perpendicular to the rotating shaft is approximately an obtuse triangle, the contact area between the bottom surface of the supporting seat 3 and the base 1 is large, the base 1 is ensured to stably support the supporting seat 3 and the motor 2, and the top surface is inclined, so that the dead weight of the motor 2 can be fully utilized, and the abnormal deflection of the supporting seat 3 in a normal working state is avoided.

The arrangement form of the spring 4 can adopt two modes, one mode is that an extension spring is adopted, two ends of the spring 4 are respectively connected with the inner side of the tail end of the supporting seat 3 and the base 1, the spring 4 tensions the tail end of the supporting seat 3 and the base 1 together in a normal state, and when an abnormal state occurs, the spring 4 is stretched to play a role in buffering; another mode is to adopt a compression spring, as shown in fig. 1, when adopting the compression spring, a screw rod 5 needs to be additionally arranged to serve as a guide function, one end of the screw rod 5 is hinged to the base 1, so that the screw rod can rotate along with the deflection of the supporting seat 3 without interference, the other end of the screw rod passes through a through hole at the tail part of the supporting seat 3, an adjusting nut 6 is arranged on the screw rod 5, the spring 4 is positioned between the supporting seat 3 and the adjusting nut 6, the working mode of the spring is opposite to that of an extension spring, under a normal state, the spring 4 compresses the tail part of the supporting seat 3 on the base 1 under the action of the adjusting nut 6, and when an abnormal state occurs, the spring 4 is. The second of the two is preferred because the force pressing the abutment 3 can be controlled by adjusting the nut 6 to set the tension with which the abutment 3 deflects.

The utility model discloses can prevent effectively that motor overload from causing the overload during operation in the production process, produce too big tension, destroy electrical equipment. The whole device is simple and easy to operate, production halt caused by equipment damage can be avoided, the production cost is reduced, the production efficiency is improved, and good economic benefits can be brought.
