The invention provides a spiral chain fastener which is high in strength, simple in operation, economic and practical, safe and reliable, and reusable; the defects that a synthetic fiber fastener cannot resist high temperature and a steel wire rope fastener is easy to break and cannot be reused are overcome; and the marine transport spiral fastener is suitable for the securing binding of wheel type automobiles and crawler type heavy-duty equipment during marine ship transport.
Description
Technical field
What the present invention relates to a kind of goods transport is solid equipment.Be applicable to that the boats and ships seat transport is wheeled, crawler type heavy duty equipment and other goods be solid binding.
Background technology
At present, in the middle of China's Shipping industry, the binding of wheel car or heavy tank and other items transportation is reinforced, generally adopt syntheticfibres fastener, steel rope, lever chain fastener system admittedly.Syntheticfibres fastener maximum securing load is 100KN, and heat-resisting quantity is poor, is applicable to binding and reinforces light equipment.Lever fastener exists safety factor low, and tension distance is fixing, and the fine setting distance is short, and the shortcoming such as take up room large.The intensity of steel rope is high, cost is low, but is easy to disconnected strand, repeatedly uses as standard equipment to exist larger potential safety hazard.At civilian transport field, steel rope generally uses as disposable reinforcing equipment.
Summary of the invention
The object of the present invention is to provide a kind of intensity high, simple to operate, the fine setting distance takes up room little, and is economical and practical, the safe and reliable and reusable spiral chain fastener of energy.It has overcome the deficiencies in the prior art.
The technical solution used in the present invention is: marine transport screw fastener by the nest seat, resemble pin, chain link, left-hand screw U-shaped bar, swivel nut, right-hand screw C shape bar, handle, ratchet, ratchet, long-link chain, upper connector etc. and form.Described nest seat is made of nest seat loam cake and nest seat base plate, and nest seat loam cake is bent into square, is provided with cross recess, and nest seat base plate is square integrally welded with nest seat loam cake.The described underfooting section that resembles is that circular card is closed the card jail with nest seat cross recess phase quinone, and top becomes " Y " shape structure, in its prong pivot pin is housed, and is connected with chain link by pivot pin.Described left-hand screw U-shaped bar one end becomes " Y " shape structure, in its prong pivot pin is housed, and is connected with chain link by pivot pin, and the other end has screw thread to be threaded with swivel nut.Described right-hand screw C shape bar one end has screw thread to be threaded with swivel nut, and the other end is C shape hook, directly is connected with the long-link chain hooking, adjusts rapidly the solid length of long-link chain system on a large scale, on the described C shape hook Spring Card is arranged, and prevents the long-link chain slippage.Described swivel nut is tubular structure, an inner end is that the minus thread other end is that right-hand screw thread matches with left-hand screw U-shaped bar and right-hand screw C shape bar respectively, play the effect of the solid chain of fine setting tension system, its outside bidirectional ratchet pawl structures that adopts, can positive and negative rotation, the chain of straining or get loose, its described handle capable of being is around 90 ° of rotations of lever pin.Described chain is long-link chain, and the chain end is upper connector, and described upper connector comprises that length articulates ring, short articulating encircled and shackle.
Described handle is installed on the handle set, can be around 90 ° of rotations of lever pin.
Described handle set becomes Y-shaped structure, and front end is circular hollow, is enclosed within fastening screw and puts, and the center is provided with a blind hole, and ball and spring are installed.
The present invention adopts said structure, can all be made of metal, and compared with prior art has the following advantages: having overcome the syntheticfibres fastener can not resistant to elevated temperatures shortcoming, has overcome simultaneously the shortcoming of the easy fracture of wire of steel rope disconnected strand.From its own advantages, simple in structure, easy to use, but partial disassembly's reparation is reusable.Arrange according to actual needs the nest seat, alerting ability is high, uses the solid equipment quantity of system few, and actv. utilizes the cabin capacity, has improved economic benefit.The present invention will link up with and the screw rod unit design, the needs of quick adjustment chain length have been satisfied, make again compact overall structure, adopting long-link chain to make the dragline rope compares with other chains, alleviated weight, reduce labour intensity, adopted the screw-tightened structure to play the effect of finely tuning tensioning chain, laborsaving convenience.
