Abstract
The invention belongs to the technical field of lifting hook dropping-prevention devices, and particularly relates to a dropping-prevention device of a lifting hook. Safety of the lifting hook in the lifting process can be effectively ensured. According to the specific scheme, the lifting hook dropping-prevention device comprises the lifting hook, an arc-shaped plate and a check block; the arc-shaped plate is made along the outer circular arc of the lifting hook, the upper end of the arc-shaped plate and a hoop are welded together, and the hoop is movably connected to the lifting hook through a bolt; the lower end of the arc-shaped plate is hinged to the upper end of a blocking piece, the lower end of the blocking piece and the lower end of the check block are connected through a steel wire, the upper end of the check block is hinged to a hook head closing opening of the lifting hook, and the lower end of the check block rotates around the hinge position of the upper end so as to achieve opening and closing of the hook head; and a spring is elastically arranged between the check block and the lifting hook in a press-fit manner and achieves the return effect. During use, the whole operation process can be independently completed only by one operator, operation is convenient, and safety and reliability are achieved.
Description
Technical field
The invention belongs to lifting hook looseness preventing device technical field, be specifically related to the anti-drop device of a kind of suspension hook, it is possible to be effectively ensured suspension hook safety in hoisting process.
Background technology
According to the requirement of GB6067.1-2010 " safety rules for lifting appliances ", lifting hook looseness preventing device (also referred to as anticreep rope band blocking device), when using crane hanging component goods, for preventing goods from surprisingly breaking off relations, should be installed on suspension hook by enterprise.Tradition lifting hook looseness preventing device, i.e. torsion shrouding formula suspension hook, its anticreep shrouding is articulated with hook neck place.One, mounting structure is unreasonable, suspension hook is fixed hanger width too narrow, and anti-drop device is only fixed by biside plate, anti-drop device all right left and right play after fixing, it is easy to make connecting bolt flexural deformation and back-moving spring damage.Its two, connect use plain bolt, nut cannot pretension cause nut easily loosen and come off, cause that anti-drop device lost efficacy, cause great potential safety hazard to the personal safety of live operator and site safety.Its three, tradition anti-drop device be made up of double torsion spring and safety card, the limitation designed, production process uses very inconvenient.
It addition, traditional anti-drop device, when unloading goods, the fixing suspension hook of a hands of operator is motionless, and it is motionless that another hands holds goods, in addition it is also necessary to another one operator coordinates breaks off relations steel wire rope.
Summary of the invention
For solving the technical problem that in the suspension hook hoisting process that prior art exists, poor safety performance, lifting hook looseness preventing device gross distortion and back-moving spring damage, the invention provides a kind of novel lifting hook looseness preventing device, ensure to use in production scene during crane hanging component goods and do not have towing hook phenomenon, it is possible to effectively prevent anti-drop device to lose efficacy.
For achieving the above object, the technical solution adopted in the present invention is: lifting hook looseness preventing device, including suspension hook, arc and block, arc is one piece of arc made along suspension hook external arc, the upper end of arc and anchor ear weld together, anchor ear is movably connected on suspension hook by bolt, the lower end of arc and the upper end thereof of catch, the lower end of catch is connected by steel wire with the lower end of block, the upper end thereof of block closes mouth at the gib head of suspension hook, the lower end of block rotates, around the hinged place of upper end, the opening and closing realizing gib head, between block and suspension hook, elasticity is pressed with spring, spring plays the effect of return.
One end of steel wire is hinged on the lower end of catch, the other end of steel wire is hinged on the lower end of block, arc, catch, steel wire and block are together to form a four-bar linkage structure, are realized the opening and closing of suspension hook gib head by the rotation of block, to ensure suspension hook security performance in hoisting process.
The lower end of catch forms a handle that can grip, and is controlled the rotation of block by swing handle.
The present invention in use, has only to operator's complete independently in whole operating process, easy to operate, safe and reliable.And the spring of reset is without influence on the normal use of suspension hook, device intensity is high, is unlikely to deform, it is to avoid the damage that mutual extruding causes.The connected mode of the present invention adopts self-locking nut and rivet, and device entirety is solid and reliable, low cost of manufacture, good economy performance.

Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As shown in figs. 1-7, lifting hook looseness preventing device, including suspension hook, arc 1 and block 2, arc 1 is one piece of arc 1 made along suspension hook external arc, and the upper end of arc 1 and anchor ear weld together, and anchor ear is movably connected on suspension hook by bolt.The lower end of arc 1 is coated with a pipe, catch 3 is trench structure, the upper end of catch 3 is more than lower end, the biside plate of catch 3 upper end is installed on pipe, the lower end of catch 3 is connected by steel wire 4 with the lower end of block 2, and the upper end thereof of block 2 closes mouth 5 at the gib head of suspension hook, and the lower end of block 2 rotates, around the hinged place of upper end, the opening and closing realizing gib head, between described block 2 and suspension hook, elasticity is pressed with spring 6, and spring 6 also functions to the effect resetted simultaneously.
One end of steel wire 4 is hinged on the lower end of catch 3, the other end of steel wire 4 is hinged on the lower end of block 2, arc 1, catch 3, steel wire 4 and block 2 are together to form a four-bar linkage structure, the opening and closing of suspension hook gib head is realized, to ensure suspension hook security performance in hoisting process by the rotation of block 2.
The lower end of catch 3 forms a handle that can grip 7, and handle 7 is riveted on handle 7, is controlled the rotation of block 2 by swing handle 7.
