Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of master-slave mode twin-roll stranded wire apparatus on maneuvering milling machine.
Background technology
Field work is because of nothing electricity, road bumpiness, and the mechanical device used all wishes that its volume is little, lightweight, rapid operation.Need in air line working process in the wild to move to the certain altitude such as electric wire, and form certain tension force, the equipment that this operation adopts is maneuvering milling machine.Maneuvering milling machine primarily of power plant, reversing arrangement, retarder, stranded wire apparatus composition, be a kind of when being mainly used in realizing electric power conveying stringing, forest department's lumbering by wood of cutting down trees to put down the device on mountain from mountain.This device utilizes power plant (vapour, diesel engine) to produce active force, utilizes manpower traction to move to the certain altitude such as electric wire, and form certain tension force; Or by cut down trees wood be put under mountain from mountain.At present, motor-driven wire twisting equipment used twisted wire cylinder many employings monotubular pyramidal structure or twoly drive double-barrel structure.Its stay cord lack of alignment of monotubular pyramidal structure and rope between mutually extrude, during artificial bracing wire, labor strength is large.Double-barrel structure all adopts cylinder before and after equal diameter to drive simultaneously, and main driven gear is interfered mutually, forms additional resistance, the wearing and tearing of aggravation transmission gear; And productive costs is high.
Summary of the invention
The purpose of this utility model is the above-mentioned defect for existing in prior art, provides a kind of master-slave mode twin-roll stranded wire apparatus reducing stay cord wearing and tearing, reduce hand labor intensity, save production cost.
The purpose of this utility model realizes by the following technical solutions: this master-slave mode twin-roll stranded wire apparatus, and it comprises front roll and back roll, and two cylinder surfaces all have spiral arc groove; Front roll is installed between cylinder front stall and cylinder back seat by front roll axle, cylindrical roller bearing, front roll bearing seat; Back roll is installed between described cylinder front stall and cylinder back seat by back roll axle, cylindrical roller bearing, back roll bearing seat and front roll side by side; The axle head that described front roll axle is positioned at cylinder front stall stretches out and connects with the reducer output shaft of power plant; Between described front roll and back roll, top is provided with the positioning support strut parallel with back roll axle with front roll axle, and the two ends of positioning support strut are fixed between cylinder front stall and cylinder back seat by nut, packing ring; The side of described cylinder back seat is provided with bearing, and bearing is connected with left half support and right half support, the centre of left half support and right half support is provided with bolster.
Concrete, described in be positioned at cylinder front stall and cylinder back seat front roll bearing seat outside be respectively equipped with protecgulum and back seat left sealing cap; Front stall capping and back seat right aling cap is respectively equipped with outside the described back roll bearing seat being positioned at cylinder front stall and cylinder back seat; The inner side of described cylindrical roller bearing is equipped with back-up ring.
Concrete, described front roll radius is greater than back roll radius, the width of perficial helical arc groove axile displacement half groove of described front roll and back roll.
Twisted wire twin-roll of the present utility model adopts the bicylindrical roller frame of single driving type (master-slave mode) scrolling bands arc groove in the same way side by side; Namely only with an input shaft, the output torque from retarder direction is transferred to drive roll, follower rollers, by hauling rope driven rotary, inputs driving torque by retarder direction.Swift is drive roll, drives doffer to rotate, and realize traction by hauling rope.This device by front roll axle input power (moment of torsion), by power by the arc groove on front roll by transmission of power to the steel rope be wrapped on cylinder, steel rope drives on the one hand back roll to rotate, and outputs power on the other hand, realizes acting.Forward and backward cylinder arc groove axile displacement half groove realizes stay cord ordered arrangement.Artificial lead pulling force significantly can be reduced by the friction drag between forward and backward cylinder arc groove and stay cord.
Compared with prior art, the utility model has following beneficial effect:
(1) cylinder of the present utility model and stay cord contact surface adopt arc structure, solve in the forward and reverse twisted wire process of current taper monotubular and cause stay cord wear problem because mutually extruding between stay cord, will significantly increase the effective area of contact between twisted rope and cylinder when the identical winding number of turns and diameter of cylinder do not increase simultaneously.
(2) significantly can increase its twisted wire tension force in the identical pulling force situation of stay cord, reduce the labour intensity of bracing wire workman.
(3) adopt master-slave mode (list) drive pattern because of eliminating the transmission gear on two, thus solve current generally employing Dual Drive twin-roll engaging gear and interfere with each other problem.
(4) every covering device at least reduces three gears, with a transition gear axle, and cost-saved more than 300 yuan.
