Description
Technical field
The utility model relates to fishing net and makes the equipment technology field, relates in particular to the radial expansion mechanism of the off line beam-forming arrangement of a kind of half-blank net sheet.
Background technology
The off line bunchy of net sheet generally all adopts cylinder rotation canoe, carries out with pencil when twining owing to the net sheet, so cylinder appearance axial design becomes Open architecture; The cylindrical that promptly forms cylinder has the space, like cell sructure, fixes with the head of convenient net sheet; Yet after twining bunchy, if cylinder one end is open, the length of cylinder can not be oversize; Otherwise whole device is unstable; And the net bundle that has twined is taken off quite difficulty, adopts axial promotion method resistance disaster to unload, and also possibly cause damage to the net sheet.
Summary of the invention
The objective of the invention is to adopt the shelf structure mode of twining automatically in order to solve the off line bunchy of half-blank net sheet; And go out the problem that is difficult to unload behind the existing network sheet bunchy; A kind of radial expansion mechanism of the off line beam-forming arrangement of half-blank net sheet of reasonable in design is provided, to reach the purpose that easily unloads behind the net sheet bunchy.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: the radial expansion mechanism of the off line beam-forming arrangement of a kind of half-blank net sheet; Comprise the center shaft that twines frame in the off line beam-forming arrangement, the polished rod that is distributed in the center shaft both sides; An end that it is characterized in that described center shaft is a tubular structure; In the hollow tubular of center shaft nut is housed, the hollow tube wall of center shaft is provided with two chutes with shaft centre line symmetry, establishes the screw rod that cooperates with nut; One end of screw rod connects first connecting rod; The other end of first connecting rod is connected the middle part of second connecting rod, and an end of second connecting rod is hinged with the polished rod that twines frame, and the other end of second connecting rod and center shaft outer wall are hinged.Because screw rod is arranged in the center shaft of hollow tubular, an end of first connecting rod need be connected to chute, and the quantity of polished rod generally is no more than 4 of symmetry, to guarantee the intensity of center shaft; When screw rod rotates, move axially along nut, screw rod drives first connecting rod; First connecting rod pushes away or spurs second connecting rod, shifts polished rod onto with the center shaft position maxim through this connecting rod auxiliary structure, and locking; Make the net sheet under tensioning state, twine operation, behind the winding structure, axially draw pine to polished rod along center shaft through connecting rod is secondary; The reduced diameter that is equivalent to whole winding frame, the net sheet easily moves vertically, so that deviate from.Polished rod moves with two fulcrums and is as the criterion; The end positions that is polished rod is hinged through two second connecting rods and center shaft, because one twine and can carry out many bunchy operations of netting sheets on the frame, so when polished rod moves; Whole winding frame external diameter all can dwindle, and all net sheets can both unclamp.In addition, because the net sheet is soft ring bundle, the removable polished rod that then twines on the frame is one or more pairs of can both achieving the goal.
As preferably, described center shaft outer wall is provided with first free bearing, and polished rod is provided with second free bearing, and second connecting rod is connected with center shaft, polished rod respectively through first free bearing, second free bearing.In first free bearing, second free bearing or be provided with bearing or bearing shell,, reach the labor-saving effect to reduce friction.
As preferably, described first connecting rod meets with the fulcrum that is connected of second connecting rod: this fulcrum to the distance of first free bearing greater than the distance of this fulcrum to second free bearing.According to lever principle, the fulcrum of first connecting rod is positioned at the end of second connecting rod towards the second free bearing direction, reaches push-and-pull labour-saving purpose.
As preferably, an end of described screw rod is hinged through connector and first connecting rod, and described connector passes chute, and the thickness of connector is less than the groove width of chute.Adopt the connector structure to make easily, establish symmetrical hinge hole on the connector, when screw rod moves, the motion of articulated joint pulling first connecting rod.
As preferably, described polished rod is provided with two pairs of symmetry, and chute is provided with four of symmetry, connector or one-tenth " ten " font.Rotating accuracy did not require when net sheet bunchy twined, and two secondary polished rods also need not equate with the distance of center shaft.
As preferably, the outside one end of described screw rod is provided with the crank snap close.The crank snap close can adopt multiple version, as establishing two short pins of symmetry radially on the axle, radially establishes hole etc. in the screw rod end, and crank can unload during operation.
As preferably, described nut is a T type nut, nut or be the bull nut.T type nut, bull nut can reach the purpose of big stroke with the minimizing revolution.
As preferably, the external diameter that described center shaft is equipped with nut one end is provided with bearing guard.Center shaft need be fixed on the pedestal of equipment through bearing seat at last, on the center shaft external diameter belt pulley is housed in addition, and belt pulley is connected with actuating device.
As preferably, only be provided with two second connecting rods between described every polished rod and the center shaft, second connecting rod is separately positioned on the two-end part of polished rod.Two second connecting rods are as parallel mobile rocking bar, again as polished rod and center shaft bonded assembly skeleton.
The beneficial effect of the utility model is: axially polished rod is drawn along the winding frame to push away the degree of tightness that can accomplish the net sheet, simple to operate light, rational in infrastructure, cost of manufacture is low, and is practical.
