Description
Technical field
The utility model relates to Heavy Equipment-hoisting device, is specifically related to a kind of protecting device for wire rope for Heavy Equipment-hoisting.
Background technology
Lifting, the transfer of heavy wares and heavy wares component are very important cargo handling operations in factory; It often needs to use major diameter steel rope, comes rotary heavy-duty equipment and component realize it and install by lifting major diameter steel rope.The general practice is hung on crane hook by major diameter steel rope, realizes heavy wares, the rotation of heavy wares component or state adjustment by the slip of major diameter steel rope on suspension hook of hanging lifting part; The drawback of this operating mode there is potential safety hazard, in hoisting process, major diameter steel rope abrasion is very severe, the personnel that easily cause injure and the heavy losses such as device damage, and the cost of major diameter steel rope own is higher, scrap because loss causes too soon or too greatly, considerably increase the productive costs of enterprise undoubtedly.
Application number be 2011103368736 Chinese patent disclose the patent of invention that name is called " hoisting protection device of steel wire rope "; it comprises finished angle steel, reinforcing bar, abrasion-proof rubber cushion, countersunk head screw; described finished angle steel is L-type; the outside angle position of angle steel is all fillet; the vertical plane of L and plane of structure all have groove; fixedly abrasion-proof rubber cushion is housed with countersunk head screw in groove, L-type angle steel back side installed parallel has two reinforcing bars, can hold steel rope between two reinforcing bars.Its shortcoming is that the steadiness that abrasion-proof rubber cushion is fixed on angle steel by countersunk head screw is not strong, and rubber pad is not long for service life under the gravity friction of steel rope, still there is potential safety hazard like this in actual hoisting process.
Summary of the invention
The purpose of this utility model is to provide a kind of protecting device for wire rope for Heavy Equipment-hoisting, can solve heavy wares and component steel rope in hoisting process and easily wear and tear and even rupture and cause safety misadventure or increase the problem of enterprise's productive costs.
In order to realize above object; the utility model provides a kind of protecting device for wire rope for Heavy Equipment-hoisting; comprise U-shaped shackle, shackle pivot pin, support wheel and steel rope; fender guard is installed on crane hook by U-shaped shackle; steel rope one end connects heavy wares; shackle pivot pin is through support wheel and the two ends two-arm through U-shaped shackle; support wheel be can around shackle pivot pin rotate rotary pulley; rotary pulley is provided with a smooth half slot, and the steel rope other end is fixed on described smooth half slot.
Further, between the two-arm of U-shaped shackle, be also provided with a screens block, tangent above described screens block and steel rope.
Further, the diameter of section of steel rope is not less than 112mm.
Further, the two ends of shackle pivot pin are also provided with captive nut.
The protecting device for wire rope for Heavy Equipment-hoisting that the utility model provides; steel rope is supported by rotary pulley; and rotary pulley is provided with the smooth half slot supporting with steel cord structure size; can ensure that when lifting the friction that steel rope and rotation are slided is very little; greatly improve the service life of steel rope; screens block is set on a steel cord simultaneously, steel rope effectively can be prevented excessive at smooth half slot bias internal, improve Hoisting Security.
