Abstract

The utility model is formed by that a chain protecting device is arranged between two symmetry type C-shaped hooks. The utility model solves the damage that when the publicly known double hook rolled steel sling handles and lifts the rolled steel in that air, the lifted rolled steel impacts other objects, or the publicly known double hook rolled steel sling is used for placing the rolled steel at the ship hatch in the harbor handling process, the double hook can release the load and can generate the outward movement, the rolled steel is released and falls down, which can causes the accidents such as the human body casualty, etc. The utility model has the advantages of simple structure, light weight, simple manufacture, and long service life; the structure can ensure the safety in the operation. The utility model is suitable for lifting various tonnages of rolled steel.

Description

Chain protection type rolled steel sling

The utility model be a kind ofly be used to load and unload, the chain protection coil steel spreader of handling coil.

What adopt in known coil steel spreader is the coil steel spreader that single hook or double hook are formed, its single hook block of this type of suspender has the too heavy shortcoming of deadweight, the double hook suspender has when coil is lifted by crane aloft if collide other objects or shelve the instantaneous of ship Hatch Opening in harbour handling, double hook will discharge load in moment and outwards produce and move, and cause rolling up the break off relations harm of the grave accident of falling of net.

The purpose of this utility model is a kind of coil steel spreader that adopts protecting structure for chain of design, and it has from heavy and light, and bearing load is big, simple in structurely easily makes long service life and advantage such as safe, reliable and convenient.

Technical solution of the present utility model is: a kind ofly be used to load and unload, the chain protection coil steel spreader of handling coil; it is is steel rope (1) by hanging, to hang be that steel rope (2), joining shackle (3), joining shackle (4), handle (5), handle (6), C type hook (7) and C type hook (8) are constituted, and it is characterized in that: it is to adorn a chain protection equipment (15) in the lower end of C type hook (7) and C type hook (8) to constitute.

Chain protection equipment (15) be the lower end of C type hook (7) adorn one the protection hook (9), the lower end of C type hook (8) adorn a chain joining shackle (13), the protection chain (14) the other end on be equipped be equipped with on back up ring joining shackle (11), the back up ring joining shackle (11) protection iron ring (10).

Because the utility model adopts chain protection equipment; have simple in structure, from heavy and light, make easy; and structurally guaranteed in the coil handling, to have safe and reliable advantage; collide other objects or shelve the instantaneous of ship Hatch Opening in harbour handling thereby overcome the coil that known double hook coil steel spreader hung in the lifting of loading and unloading handling coil in the air, double hook will discharge the harm that load produces the outwards mobile accidents such as personal injury that cause coil to fall causing in moment.

Routine accompanying drawing has been described an embodiment of the present utility model down.

Accompanying drawing is a structural representation of the present utility model.

With reference to accompanying drawing; chain protection coil steel spreader is to be equipped with respectively in the upper end of C type hook (7) and C type hook (8) that to hang be steel rope (1) and to hang be steel rope (2); the side of C type hook (7) and C type hook (8) is equipped with handle (5) and handle (6) respectively; protection hook (9) is equipped with in the bottom of C type hook (7); chain joining shackle (13) is equipped with in the bottom of C type hook (8); one end of protection chain (14) is fixed on the bottom of C type hook (8) by chain joining shackle (13); on the other end of protection chain (14) back up ring joining shackle (11) is housed, protection iron ring (10) is housed on the back up ring joining shackle (11).

When using the utility model; at first determine chain length, slightly put surplus when determining, make chain when normal operation according to the coil width of handling; be in the state of not stressing, the back up ring joining shackle (11) that will have protection iron ring (10) then is contained in an end of determining good length.This moment when coil by C type hook (7) and (8) hook on after; the workman only needs protection iron ring (10) is hung on the protection hook (9); hoisting crane can be that the coil on the double hook is lifted by crane in steel rope (1) and (2) by hanging; large-scale like this coil is aerial in lifting job; even the possibility that there are other objects of collision unavoidable moment or shelve the ship Hatch Opening; because chain protection equipment; the grave accident that does not also cause double hook outside moving of moment and cause coil to fall; ensured safety in production technically, the workman is simple to operate in the handling process simultaneously.

The utility model is rational in infrastructure, and is easy to operate, and use on the border factually, and handling large-tonnage coil has in batch especially improved the loading and unloading quality of coil significantly, has ensured safety in production.
