Abstract

The utility model relates to a double-safety elastic rope, which belongs to a conveying cable. The utility model is used for binding and loading cargoes by railway, highway and water transportation. The utility model is characterized in that the rope is composed of a degumming natural fiber rope at both end segments, a black rubber elastic cylinder in the middle segment, and an auxiliary safety rope bridged over both ends of the cylinder and forming an arch shape usually; the three components are adhered together by vulcanization. The utility model has the advantages of simple structure, convenient operation, low rope consumption, easy binding, labor saving, no loosening in transportation, no damage to cargoes, easy fabrication, low cost, reusability, wide range of tensile strength application, etc.

Description

The double insurance stretch cord

A kind of double insurance stretch cord belongs to transportation cable technical field, is mainly used in railway, highway, the restraint of loads of water transportation goods loading and reinforcing.

In the prior art, railway, goods loading and reinforcing always is to bundle with rope in highway and the water transportation, by the manpower tension, in transit, because the car and boat that transport point is used travel and jolt, space between each individuality of goods dwindles, cause lash rope loose, the loosening dislocation of rope often appears, thread off, tarpaulin is blown up, cause and lose goods or goods damage accident such as drench with rain, cause serious economic loss for the country and the owner of cargo and cause dispute between the owner of cargo and the acknowledgement of consignment person, simultaneously also serious threat transportation safety, particularly all to the high speed development, existing loading and reinforcing more can't adapt to this development tendency with rope to car and boat.

The purpose of this utility model is to provide a kind of consumption few, and easily binding is laborsaving, and binding firmly, and is not loose in transit, guarantees transportation safety, simple in structure, makes the double insurance stretch cord that cost is low easily.

Characteristic according to elastic principle and rubber, at existing questions in the prior art, basic design of the present utility model is: will have rope commonly used now and be divided into three sections, middle one section has the elastic rubber rod of identical tensile strength instead and is arch at ordinary times one of this rod two ends cross-over connection, parallel arranged side by side and stressed auxiliary insurance with rod when this rod is stretched to limiting length, the three is by vulcanizing bonding forming.

Double insurance stretch cord described in the utility model, the natural fiber rope 1 that is positioned at the two ends section by interconnecting constitutes with the caoutchouc elasticity cylinder 2 that is positioned at its interlude, it is characterized in that this its above-mentioned natural fiber rope 1 of restricting is served as reasons comes unstuck that vegetable fibre spinning forms, above-mentioned caoutchouc elasticity cylinder 2 for make with black rubber and be provided with one section and be the auxiliary insurance 3 that arch is connected across elastic cylinder 2 nearly two ends at ordinary times; The two ends of this auxiliary insurance 3 are wrapped in the interior knotting of caulking of the above-mentioned 1 liang of the inner of natural fiber rope of coming unstuck respectively and are bonded together by 2 sulfurations of above-mentioned black rubber elastic cylinder.

Above-mentioned black rubber elastic cylinder 2 is solid barred body with one section hollow centre respectively for two ends.

Above-mentioned auxiliary insurance 3 is a stressed manmade fibre cordage side by side in parallel when above-mentioned black rubber elastic cylinder 2 is stretched over limiting length.

The utility model has the advantages that: simple in structure, easy to use, bundle identical goods and compare with the rope amount few with existing rope, binding easily, and is laborsaving during tension, do not travel with car and boat and slacken, safe in utilization, goods is not impaired, easy processing and fabricating, and cost is low, reusable, tensile strength is more than 332kg, and operating ambient temperature is-45 ℃-+45 ℃, applied range.

Accompanying drawing 1 is the utility model bulk shape structural representation;

Accompanying drawing 2 cuts open section-drawing for what amplified along axis office.

Further describe architectural feature of the present utility model as follows with most preferred embodiment in conjunction with the accompanying drawings: two sections respectively have sufficient length (deciding) the plant towline 1 that comes unstuck that high-quality flaxen fiber twisting forms with coming unstuck with purposes in the middle of in the caulking at their two ends, twine earlier and its residue length of tiing a knot equals the Kapp dragon matter auxiliary insurance 3 of elastic cylinder 2 limit of stretch length, and then one section of the hollow centre that respectively adapts with one section external diameter with above-mentioned natural fiber rope 1 with two ends for solid black rubber rod 2 through vulcanizing with above-mentioned two 1 and 3 bonding being integral of restricting.

Change as present embodiment:

The used raw MAT'L of each parts can suitably change.

Claims

1, a kind of double insurance stretch cord, the caoutchouc elasticity cylinder [2] that is positioned at the natural fiber rope [1] of two ends section by interconnecting and is positioned at its interlude constitutes, it is characterized in that this its above-mentioned natural fiber rope [1] of restricting is served as reasons comes unstuck that vegetable fibre spinning forms, above-mentioned caoutchouc elasticity cylinder [2] for make with black rubber and be provided with one section and be the auxiliary insurance [3] that arch is connected across the nearly two ends of elastic cylinder [2] at ordinary times; The two ends of this auxiliary insurance [3] are wrapped in the interior knotting of caulking of above-mentioned natural fiber rope [1] two the inner of coming unstuck respectively and are bonded together by above-mentioned black rubber elastic cylinder [2] sulfuration.

2, double insurance stretch cord according to claim 1 is characterized in that above-mentioned black rubber elastic cylinder [2] is solid barred body with one section hollow centre respectively for two ends.
