SU35350A1 - Magnetic grip - Google Patents

Description

The invention relates to magnetic grips equipped with safety levers for the purpose of preventing the load being lifted.

In the proposed magnetic gripper to the safety levers, a frame is placed on the right axis attached to them, supporting the levers, which are automatically retracted to the side under the weight of the electromagnet, which descends to the cargo to be gripped, and when released, which release the levers again to the active position.

In FIG. 1 is a front view of the grip; FIG. 2nd side view.;. ,

The proposed magnetic gripper consists of an electromagnet 1, suspended by chains to the axis 4, which also serves as a point of suspension for the safety levers 2 ,. connected to this axis 1 in a well-known way with the help of bolts, springs and a screw. The pivoting support frame 8 is attached to the axis 3 passing through the levers and connected with a crane hook to keep it in equilibrium

frame when lifting the whole grip.

For gripping the load, the support frame 8 with its lower channels 7 is placed on the floor, which causes the hoisting rope to be released, the point of suspension of the levers 2 passes into point 3 (Fig. 1), and the levers 2, turning on axis 3 under the influence of the weight of the electromagnet, retract side, allowing the magnetic seizure to attract cargo.

When all the gripper is lifted with the attracted load, the levers 2, changing the suspension point again, turn in the opposite direction, being located under the gripped load 6 in order to protect it from falling in the event of a possible cessation of current.

The subject matter of the invention.

A magnetic gripper, provided with a pivoting safety lever, characterized in that the safety lever 2 attached at one end to the magnet suspension axis 1, for the purpose of automatically pulling it sideways when gripping and setting into active position when lifting the load, is attached to it on the axis 3 support frame 8.
