The invention discloses a crane lifting hook protection device, relating to crane supporting devices. The crane lifting hook protection device is characterized in that a collision-free device is mounted at the front end of a crane jib through bolts; the collision-free device covers a pulley block and a lifting hook; two buffer springs are mounted inside the collision-free device. The collision-free device comprises a protection cover, the buffer springs and mounting tables; the protection cover is of a rectangular cover barrel structure with an open bottom, and a mounting opening is formed in one side, close to the crane jib, of the top of the protection cover; the mounting tables are symmetrically mounted at the two sides of the protection cover through screws; the buffer springs are mounted on the mounting tables. An included angle between the axis of each mounting table and the internal wall of the protection cover is 30-45 degree. The distance between the lower parts of the two buffer springs is 1 / 2 the width of the lifting hook. The edge of the bottom of the protection cover is ground into a round edge. The crane lifting hook protection device disclosed by the invention has the characteristics of novel structure, simplicity and convenience in manufacturing, low cost, convenience in mounting, convenience in use, safety and reliability and the like, thereby being a novel crane lifting hook protection device having both economical efficiency and practicability.
Description
technical field [0001] The crane hook protection device of the present invention relates to a crane supporting device. Background technique [0002] Many industries now need to use lifting equipment. The hook on the lifting equipment swings with the movement of the boom after being retracted. When the hook swings, it often touches other equipment, causing unnecessary losses. The hook moves upward under the action of the traction wire rope. When the wire rope stops working, the hook moves upward inertially and collides with the pulley block, causing equipment damage. In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a novel crane hook protection device to overcome the problems existing in the prior art. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the invention is to study and design a novel crane hook protection device. The utility model is...
