The specific implementation mode is as follows:
the invention is further illustrated by the following specific examples.
A permanent magnet non-contact backstop is used for emergency braking when a conveyor reverses and comprises an end cover 13, a sliding groove 11 is formed in the end cover 13, one end of a permanent magnet support 14 slides in the sliding groove 11, the other end of the support 14 is connected with a permanent magnet 10, a permanent magnet support 15 which is a rigid beam is arranged on the end cover 13, the other end of the support is connected with a permanent magnet support 2, the permanent magnet 10 is installed on the permanent magnet support 2 through a pin shaft 5 and can rotate around the permanent magnet support, a spring 1 is connected between the permanent magnet 10 and the permanent magnet support 2, a permanent magnet 8 is installed on a brake shoe 9, the brake shoe 9 is connected onto the end cover 13 through a brake shoe support 12, and the brake shoe support 12 is an.
For the selected materials, except for the part generating the permanent magnet braking force, antimagnetic treatment is needed to prevent the interference of the permanent magnet.
When the conveyor normally runs, namely the roller outer ring 6 rotates anticlockwise, the check sheet 7 on the conveyor can collide with the permanent magnet 10, one end of the permanent magnet 10 is connected with the spring 1, so that the permanent magnet 10 can compress the spring 1, the spring is fixedly connected on the non-rotatable permanent magnet support, and the brake shoe cannot be influenced by the force generated by the permanent magnet 10.
When the conveyor is reversed, namely the outer ring 6 of the roller rotates clockwise, the anti-stop sheet 7 on the outer ring rotates, the protruding parts on the permanent magnets 10 are driven to move together, at the moment, the permanent magnets 10 stretch the spring 1, the permanent magnets 10 rotate on the permanent magnet support around the pin shaft 5, the permanent magnet supports 14 move along the sliding grooves 11, when the conveyor moves to the radial direction of a circle, the two permanent magnets can generate magnetic force, because the permanent magnets 8 are installed on the brake shoes 9, the brake shoes 9 are pushed to move towards the roller shaft 3, and because the brake shoe supports connected with the brake shoes 9 can be bent, when the repulsive force between the permanent magnets is large enough, the brake shoes can be made to tightly hold the roller shaft 3 in an emergency manner, and the number of the permanent magnets 10 can be added in the radial direction and the axial direction in the.
