Cable is not rubbed, after unfolding, in addition it is also necessary to wire is tensioned to the degree being suitable for by pulley block.Existing unwrapping wire is sliding
The weight of wheel is big, and rolling pulley needs the power used relatively big, and consumable material, and cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of pulley block, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of pulley block, including drum, reinforcement, wheel hub and web, the edge of described drum is provided with groove, drum with
Connect by web is fixing between wheel hub, web is provided with 6 lightening cores altogether, between the lightening core on web, is provided with reinforcement；
Described wheel hub is provided with axis hole, and the edge of wheel hub is provided with 9 screw holes altogether；It is provided with enhancing plate in wheel hub, strengthens and offer on plate
Porose, when carrying out the casting of whole pulley block, enhancing plate is placed in casting mold cavity, pours nylon material；Strengthen
Steel plate selected by plate, primarily serves and prevents from deforming when pulley expands with heat and contract with cold.
As further program of the utility model: the surface of described groove is arc-shaped, and smooth surface.
As further program of the utility model: described lightening core is fan-shaped, the two sides of web is equipped with reinforcement.
As further program of the utility model: be provided with ball bearing and punching steel by screw in described wheel hub
Plate.
As further program of the utility model: described drum, reinforcement, wheel hub and web all use nylon material system
Become.
Compared with prior art, this pulley block, the surface of the groove of drum is arc-shaped, and smooth surface, protection electricity
Line is not by friction damage, and the lightening core on web can reduce the weight of pulley, makes pulley be more easy to rotate, reduces material consumption,
Reduce cost, it is simple to promote the use of, pulley entirety use nylon material make, the chemical stabilization of nylon material, will not corrosion,
Resistance to impact is good, has preferable abrasion performance, thermostability, tolerance to cold and insulating properties, anti-limited slip wheel casting time expand with heat and contract with cold and
Damage, it is to avoid electric wire breakage makes pulley conduction produce potential safety hazard；Owing to being provided with enhancing plate in wheel hub, strengthen and open on plate
It is provided with hole, when carrying out the casting of whole pulley block, enhancing plate is placed in casting mold cavity singultus, pours nylon material；
Strengthen plate and select steel plate, primarily serve and prevent from deforming when pulley expands with heat and contract with cold.
