Abstract
A kind of anti-wear web plate of roller drags iron, is related to web plate accessory, is made up of Weight plate, scroll wheel, support tube and rotating shaft screw bolt, it is characterized in that scroll wheel is fixed between Weight plate by rotating shaft screw bolt and support tube, Weight plate is fixed on by fixing bolt and dragged in iron attached plate.Bottom trawlnet web plate of the present invention suitable for various types specification.
Description
Technical field
The present invention relates to web plate accessory, especially a kind of roller for being assemblied in web plate bottom is anti-wear drags iron.
Background technology
Web plate is the important accessory of Trawl gear, and be assemblied in network interface both sides drags guiding principle, for horizontal expansion network interface.Dragging iron is
The important accessory of otter-trawl web plate, is assemblied in the bottom of web plate, increases counterweight and adjusts web plate center of gravity, drags iron to be usually fixed at net
The bottom of plate is dragged in iron attached plate, directly contact seabed, can indirectly prevent web plate polycrystalline substance to be subject to the friction in seabed and damage, because
This, drags iron general frequent and is easily changed.What is used at present drags iron mostly slot type structure, i.e. section for concave structure, is stuck in and drags
Blending bolt is fixed in iron attached plate, its weight and dimensions design alternative as needed.The material of iron is dragged for steel, by one
If corrosion and abrasion are more seriously accomplished by changing after the use of section time, and during with sea bottom friction, to seabed
Substrate ecology causes to destroy to a certain degree.A kind of roller for being assemblied in web plate bottom of present invention design drags iron, and counterweight can basis
Needs are adjusted, scroll wheel can avoiding device worn and torn by seabed, extension fixture service life, while sea can be reduced suffered by web plate
Bottom resistance, appropriateness protection seabed is ecological.
The content of the invention
Iron is dragged the present invention seeks to design and produce a kind of roller for being assemblied in web plate bottom, can as needed be adjusted and be matched somebody with somebody
Weight, and scraping of the web plate bottom to seabed can be mitigated, while reducing the frictional dissipation for dragging iron, increase its service life.
By Weight plate, scroll wheel, support tube and rotating shaft screw bolt are constituted technical scheme, it is characterized in that scroll wheel by
Rotating shaft screw bolt and support tube are fixed between Weight plate, and Weight plate is fixed on by fixing bolt and dragged in iron attached plate.
It is of the invention as needed to adjust counterweight, web plate bottom can be mitigated sidewipe collision is scraped to seabed, it is to avoid device
Abrasion to extend its service life, scroll wheel can reduce web plate with the frictional force in seabed so as to suitably reduce the resistance that web plate advances
Power, while roller advance it also avoid web plate bottom scrapes the infringement ecological to seabed that sidewipe collision is caused.

Specific embodiment
Best way of the invention is implemented in explanation below in conjunction with the accompanying drawings.
Embodiment one：The applicable web plate 1 of the present invention is the bottom trawlnet web plate of various types specification, and iron attached plate is dragged with parallel
11.The present invention is made up of Weight plate 6, scroll wheel 5, support tube 4 and rotating shaft screw bolt 8, and scroll wheel is consolidated by rotating shaft screw bolt with support tube
Due between Weight plate, Weight plate is fixed on by fixing bolt and dragged in iron attached plate.
Embodiment two：The applicable web plate 1 of the present invention is the bottom trawlnet web plate of various types specification, and iron attached plate is dragged with parallel
11.Web plate reinforcing plate 2 is the horizontal reinforcing plates of web plate bottom connection fork guiding principle, thereon welded mesh plate leaf plate, and lower weld drags iron attached
Plate 11, iron is dragged for fixation.Iron attached plate front end 3 is dragged, that is, drags one end of the direction of advance of iron attached plate 11, this end is typically designed to arc
Shape, reduces the scratch of web plate bottom and seabed.Support tube 4, polyformaldehyde material pipe is through on rotating shaft screw bolt 8, positioned at scroll wheel 5
Between both sides Weight plate 6, the position for keeping scroll wheel 5, the external diameter of pipe is 40mm, internal diameter 28mm, and the wall thickness of pipe is
6mm, length sets according to the spacing for dragging iron attached plate 11 and the thickness for dragging iron attached plate, and this example design length is 30mm.Scroll wheel 5,
Polyformaldehyde plate gear formula structure, is connected, thickness 20mm by rotating shaft screw bolt 8 with the Weight plate 6 of both sides, takes turns 83 degree of bottom angle, tooth
Wheel top arc length 30mm, the radius of the arc is 150mm, angle arc length 14mm between two gear teeth, and the radius of the arc is 75mm, in
The heart is provided with shaft hole 13.Polyformaldehyde material has high intensity, high abrasion and self lubricity, makes rubbing for scroll wheel 5 and rotating shaft screw bolt 8
Wipe power reduction, elongate member service life.Weight plate 6, steel plate, thickness is selected as needed, and this example is designed as thickness 30mm, high
Degree 120mm, length 400mm, weight is 10kg.The bottom of Weight plate connects 2 scroll wheels 5, and top is solid by fixing bolt 10
Due to iron attached plate 11 is dragged, the upside of support tube 4 is set to press close to drag the lower edge of iron attached plate 11 when fixed.Rotating shaft nut 7 is rotating shaft spiral shell
The hold-doun nut of the other end of bolt 8.Rotating shaft screw bolt 8 is Steel Bolt, is the central rotating shaft of scroll wheel 5, connects Weight plate 6, support
Pipe 4, scroll wheel 5, and fixed with rotating shaft nut 7.Bolt specification can be chosen as needed, and this example specification is M27 × 180, i.e., directly
Footpath 27mm, length 180mm, every weight about 1.15kg, can fix 3 layers of Weight plate 6.The collocation fixing bolt 10 of hold-doun nut 9 makes
With positioned at the outside of Weight plate.Be fixed on for Weight plate 6 and drag iron attached plate 11 by fixing bolt 10, Steel Bolt.Length is according to matching somebody with somebody
The quantity selection of weight plate, it is M16 × 90 that this example chooses specification, and every weight about 0.2kg can fix 2 layers of Weight plate.Drag iron attached plate
11, positioned at the bottom of web plate 1, iron is dragged for being connected, it is dual-layer Parallel steel plate, thickness of slab 16mm, spacing 50mm or so.Rotating shaft
Hole 12, the center drilling of scroll wheel 5, a diameter of 28mm in hole passes through scroll wheel, the diameter of rotating shaft screw bolt for rotating shaft screw bolt 8
It is 27mm, many 1mm are easy to the rolling of scroll wheel.This example design roller drags 3 pieces of Weight plates 6 of iron counterweight, combines each part gross weight
About 35kg, drags iron to calculate by 3 groups of this structures of single web plate counterweight, it is possible to provide web plate is with weighing about 105kg.Adjustment is such as needed, can be according to need
Adjust Weight plate quantity and change meets the bolt of length specification.
