Description

Center leads to cable lay wire rope and applies the survival capsule communication system of this steel wire rope

Technical field

The present invention relates to bear a heavy burden greatly cable communicating technology field under operating mode, relate in particular to the logical cable lay wire rope in a kind of center and apply the survival capsule communication system of this steel wire rope.

Background technology

At present, communication mode can be divided into two kinds of radio communication and wire communications by its signal transduction pathway, at small space as (little rescue hole) because the radio communication communication distance is short, and less stable, thereby more employing wire communication mode.Because optical fiber communication has advantages of long distance for data, power loss is low, quality is light, comparatively commonly used in wire communication.Due to the material of optical fiber own, under some operating mode (as remote vertically hole communication), due to reasons such as deadweight or heavy burdens, being easy to is that optical fiber damages.Current solution is to use steel wire rope to be responsible for weighing or hoisting heavy both at home and abroad, is responsible for communication with the optical fiber (cable) of tear-proof steel wire rope, although this kind method has solved the problems referred to above, shortcoming is:

1. when removing weight, need independent design optical fiber (cable) wind, make that the mechanical mechanism volume is large, Heavy Weight, design and manufacture cost be high.

When optical fiber is asynchronous with wirerope-winding speed, easily make optical fiber (cable) bend or break, this Design and manufacture required precision to steel wire rope and optical fiber (cable) wind is higher, makes communication reliability low, has increased design difficulty and has increased design and manufacture cost.

For this reason, designer of the present invention is because above-mentioned defect, by concentrating on studies and designing, comprehensively is engaged in for a long time experience and the achievement of related industry for many years, research and design goes out the logical cable lay wire rope in a kind of center and applies the survival capsule communication system of this steel wire rope, to overcome above-mentioned defect.

Summary of the invention

The object of the present invention is to provide the logical cable lay wire rope in a kind of center and apply the survival capsule communication system of this steel wire rope, it both can bear than heavy load, can realize optical fiber communication again, and, can keep the unobstructed and effective lifting of the real time communication of survival capsule, guarantee continuation and the promptness of life-saving functions.

For achieving the above object, the invention discloses the logical cable lay wire rope in a kind of center, this steel wire rope comprises multifiber steel wire, wire rope core and protective sleeve, and described wire rope core is positioned at the center of protective sleeve, described multifiber steel wire be positioned at wire rope core around, it is characterized in that:

Each center of described multifiber steel wire all has an optical fiber, at the periphery of described optical fiber around one deck protection steel wire is at least arranged.

Wherein, adopted the three-layer protection steel wire, ground floor gauge of wire minimum, the diameter of the second layer is less, the diameter maximum of compound steel silk.

Wherein, described protective sleeve is that electro-insulating rubber is made.

Also disclose a kind of survival capsule communication system of applying the logical cable lay wire rope in above-mentioned center, this survival capsule communication system comprises: communication node, hoist engine, communication terminal, survival capsule, steel wire rope tail end fixing device, optical fiber and photoelectricity slip ring; It is characterized in that:

This communication node is positioned at survival capsule, one end of the logical cable lay wire rope in described center is connected to this communication node, after the logical cable lay wire rope in described center was wound on hoist engine, its other end was connected to the steel wire rope tail end fixing device, and the optical fiber in the logical cable lay wire rope in described center is connected to described communication terminal by described photoelectricity slip ring.

By said structure, the invention has the beneficial effects as follows:

1, not only can carry larger heavy burden but also can carry out wire communication.

2, in use, only need rope woolding device of design, do not need to consider optical fiber and steel wire rope stationary problem, make larger heavy burden wire communication facility simple in structure, with low cost, reliability is high.

3, survival capsule can keep the unobstructed and effective lifting of real time communication, has guaranteed continuation and the promptness of life-saving functions.

The present invention will be further described in detail by the following specific embodiments, and will be more apparent and obvious to understand further combined with the description of the drawings.

The accompanying drawing explanation

Fig. 1 is the structural representation of the logical cable lay wire rope in center of the present invention;

Fig. 2 is the schematic diagram of the survival capsule communication system of the logical cable lay wire rope in application of the present invention center;

Fig. 3 is the enlarged diagram of circle part in Fig. 2.

Embodiment

Referring to Fig. 1; the logical cable lay wire rope in center of the present invention is disclosed; this steel wire rope comprises multifiber steel wire 1, wire rope core 2 and protective sleeve; described protective sleeve is that electro-insulating rubber is made; with tool corrosion proof and leakproof function; described wire rope core 2 is positioned at the center of protective sleeve, described multifiber steel wire 1 be positioned at wire rope core 2 around.

Wherein, each center of described multifiber steel wire 1 all has an optical fiber 4; at the periphery of described optical fiber 4 around one deck protection steel wire is at least arranged; in order effectively optical fiber 4 to be provided protection and to support; as shown in Figure 1; adopted the three-layer protection steel wire; the diameter minimum of ground floor steel wire 3; the diameter of the second layer 101 is less, the diameter maximum of compound steel silk 102, thus; three layers of setting like this; can not only effectively fill space, and by the steel wire setting of ectonexine, its load bearing effect is better.

Analyze by experiment as can be knownly, protect as the compound steel silk by shown in Figure 1, when guaranteeing lifting weight, can save the protection steel wire of 30% weight, thus can be cost-saving; And under the steel wire of same weight; its lifting weight can improve 50%; therefore, this structure can strengthen the lifting force of steel wire rope greatly, and; by test; due to the setting of such three layers, the space between the compound steel silk is little, can protect optical fiber not to be subject to outside effect of signals; therefore, can also further improve communication quality and signal strength signal intensity.

Fig. 2,3 has shown the survival capsule communication system of applying the logical cable lay wire rope in above-mentioned center, and this survival capsule communication system comprises: communication node 5, hoist engine 6, communication terminal 7, the logical cable lay wire rope 8 in center, survival capsule 9, steel wire rope tail end fixing device 10, optical fiber 11 and photoelectricity slip ring 12.
