Description
Technical field
This utility model relates to a kind of that can be widely used in Great span Poling Construction use, a kind of safe and reliable, satisfied
The releasing pulley of Great span Poling Construction.
Background technology
My company is responsible for the Ling Zhou-Shaoxing ± 800kV extra high voltage direct current transmission line engineering the Changjiang river Great span bid section of construction
Wire uses 6 × JLHA1/G4A-640/290 extra-heavy aluminium alloy stranded conductor, uses 2 × 2 to lead 3 showing and placing of the tension and lead in Poling Construction
Line.Owing to large crossing projects tension stringing height difference angle is big, wire envelope angle is big, and unwrapping wire process is in continuous climb and fall state.Walk
Plate contact releasing pulley initial stage limp cannot pass through releasing pulley, reaches critical state, and pull strength increases, limp and traction
Pipe moment passes through releasing pulley, limp and traction tube and releasing pulley is produced moment impact load, and coaster nylon6 chips damages.Company
Technical team, by the analysis to conventional large crossing projects releasing pulley damage situations, determines to make by oneself to develop novel Great span
Releasing pulley.Use Great span releasing pulley nylon6 chips to increase and strengthen steel plate form, increase the bulk strength of releasing pulley, meet
Large crossing projects construction under tension stringing needs.
Utility model content
This utility model relates to one and can be widely used in Great span Poling Construction, can improve limp by sliding during coaster
The overall impact strength of car, reduces the Great span releasing pulley of the fault rate of coaster.
This utility model is mainly characterized by: be made up of pulley, support body, yoke plate, bearing and assembly thereof, shaft device, wherein
A support body yoke plate installed above, is provided with pulley below support body, in pulley, a bearing and assembly thereof are installed in center, bearing and
Assembly internal layer installs a shaft device, and each pulley is installed two pieces of reinforcing plates, and its reinforcing plate passes through 12 interior hexagonal punching bolts
It is fixed on pulley.
This utility model is mainly characterized by: bearing and assembly thereof are made up of bearing and axial positioning sleeve.
Of the present utility model it is mainly characterized by: shaft device is made up of axle and bearing pin.
The beneficial effects of the utility model are: can improve limp and pass through the overall impact strength of coaster during coaster,
Reduce the fault rate of coaster.
Accompanying drawing explanation
Fig. 1 this utility model product structure schematic diagram；
Fig. 2 this utility model product side structure schematic diagram.
Detailed description of the invention
By detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings
As shown in Figure 1: Great span coaster, it is made up of pulley 1, support body 2, yoke plate 3, bearing and assembly 4 thereof, shaft device 5, its
Middle support body 2 yoke plate 3 installed above, is provided with pulley 1 below support body 2, in pulley 1, a bearing and assembly 4 thereof are installed in center,
Bearing and assembly 4 internal layer thereof install a shaft device 5, it is characterised in that: two pieces of reinforcing plates 6, its reinforcing plate are installed on each pulley 1
6 are bolted on pulley 1 by 12 interior hexagonal punchings, and bearing and assembly 4 thereof are made up of bearing and axial positioning sleeve, and axle fills
Put 5 to be made up of axle and bearing pin.
Main operational principle:
During large crossing projects unwrapping wire, after limp contacts with coaster 1, Great span releasing pulley nylon6 chips is used to increase
Strengthen steel plate form, use 12 interior hexagonal punching bolts reinforcing plate 6 to be fixed on pulley 1, improve the most anti-of coaster 1
Pressure shear strength.Increase the bulk strength of releasing pulley 1, improve limp by the overall impact strength of coaster during coaster, fall
The fault rate of low coaster.
