Description
Technical field
The present invention relates to a kind of tackle-block device.
Background technology
At present, on crane is determined, fixed pulley is arranged on pulley spindle by bearing typically, is then arranged on pulley spindle
On support.
When the weight heavier-weight that crane is hung, once the center of gravity of weight shifts, support will bear very big work
Firmly, the erecting device between pulley spindle and support will be destroyed, while existing pulley gear pulley in use
Groove content is also easy to produce abrasion, skidding easily occurs, causes security incident, and structure dismounting, difficult in maintenance.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art, there is provided a kind of tackle-block dress
Put.
The technical solution adopted for the present invention to solve the technical problems is：A kind of tackle-block device, with installation
The support of pulley gear, is rotatablely equipped with pulley spindle on support, some assembly pulleys are provided with pulley spindle, and support is provided with installation
There is pulley shield；
The assembly pulley includes pulley body and bearing, and the lower end of described pulley body is provided with bearing, and its top sets
The groove for having shape of cross section to be " V " type, is coated between bearing described in wearing layer on the outer surface of groove and is provided with bearing bracket stand, axle
Bolster is connected with the inner oil tube being opened on pulley spindle；Support frame and spacer are provided between adjacent two assembly pulley.
Further, the center position of described mixed wheel shaft offers oil duct, and inner oil tube is connected with oil duct, and the one of oil duct
End is connected with the L-shaped oil pipe of shape, and the top of oil pipe is provided with lubricating cup.
Further, the groove for placing dead axle plate is offered on the two ends of described sliding axle, the dead axle plate passes through
Screw bolt and nut is fixed on support.
Further, the center line of described inner oil tube is mutually perpendicular to the center line of oil duct.
The beneficial effects of the invention are as follows：Simple structure of the present invention, it is easy to use, it is wear-resistant, skidding is less prone to, carry
High safety factor, maintenance and convenient disassembly, long service life, reduces cost.
Brief description of the drawings
