Referring to figs. 1 to Fig. 3, the pipeline protection device is fit to make a chain link as in the following articulated link chain, is preferably made by plastics such as BS10VN.Because the available nylon material of relative other types, this nylon material has better flexibility and stronger impact resistance.The form of this device is that web 10 substantially perpendicularly extends between upper side edge and the lower side 12,14 in use, thereby constitutes the guide groove 16,18 of lateral openings in the respective sides of the common floor that is formed by web 10. Side 12,14 constitutes the relative supporting arm 20,22 of guide groove 16 and the relative supporting arm 24,26 of guide groove 18.
Each all has circular jut 28 supporting arm 20-26, extends internally from each supporting arm respectively, thereby constitutes the inlet 30,32 of guide groove, and throat width is less than the width of guide groove 16,18 separately.Jut 28 can form with supporting arm 20-26 is molded as a whole.
The cross section of each supporting arm 20-26 is such, is level and smooth smooth basically surface 29 in the inboard of chain link, thereby the effect of following described enhancing chain link protection pipeline is arranged.
When will be, when being inserted in the guide groove 16,18 one as cable or professional pipeline with pipeline, this pipeline is inserted into entry guide 30 (32), and because of the width of its size greater than entry guide, pipeline makes guide groove supporting arm 20, open 22 (24,26), thereby be positioned at (18) in the respective guide slots 16.By behind the entry guide, guide groove supporting arm 20,22 (24,26) returns to their original positions at pipeline, thereby prevents that pipeline from passing through entry guide 30 (32) the accidental guide grooves 16 (18) that skid off.Can see, when planning that pipeline shifted out guide groove 16 (18), can make pipeline firmly oppress guide groove supporting arm 20,22 (24,26) and make it outwardly-bent, thereby by entry guide 30 (32).Jut 28 is done the circular pipeline that prevents to block.
Form a lug 36 at an end of web 10, its thickness is less than the thickness of web 10, and its position is in the central authorities of web, by its end step that forms along web 10 direction cambers.Lug 36 has through hole 38, and forms a fork 40 at the other end of web 10, and its two arms have the hole 42 of alignment respectively.The substrate of fork 40 is made of face 43,44, these two towards interior outer rim from them to web 10 angle that tilts, intersect at common point 45 places.When the lug of adjacent chain link is arranged in fork 40, and its lug 36 is when correspondingly being arranged in the fork of adjacent chain link, and this chain link just can link to each other with adjacent link.When align in hole separately, with regard to available suitable connecting pin the mode of each chain link with articulated link chain linked together, and each chain link is interchangeable position.Web 10 is around inserting body 56 molded forming, and inserts preferably steel of body, shown in Fig. 2 a.Molding process requires to have good stickability between nylon material and steel insertion body 56.In order to reach this purpose, on the fork top internal surface 58,60 that inserts body, want embossing or cutting, thereby inserting body 56 from steel, the restriction nylon material is pulled away from.
In order to prevent moisture-induced getting rusty under underground and general environment, steel inserts body can cadmium plating, in order to prevent to peel off, each metal inserts body can cutting live whole periphery with the plastic covered that allows web 10 on its periphery, be fixed in the plastics thereby will insert body.Also have, steel insertion body can be provided with a lot of through holes, and plastics extend by these holes when molded to allow, and this inserts the body location except that helping, and also will help the annealing of material.Observed in the chain that constitutes with interconnected chain link, needs in per two chain links are installed jut 28 on the guide groove supporting arm, rather than install projection on each chain link in chain.But should be appreciated that, if desired, can on the chain link of different interval, install jut 28, really, near coal winning machine, concerning this chain, all install teat 28 on preferably adjacent several chain links.
On the outer surface of this chain link, be equiped with hanger 50 with the place of the central alignment of web 10, through hole 52 is arranged in the hanger.Hanger 50 can form with this chain link is Unitarily molded.
As shown in Figure 2, articulated links of the present invention holds cable 34a and flexible pipe 34b in guide groove separately, but should understand cable and flexible pipe that it can protect different schemes.
In the modification as shown in Figure 3, web 10a only forms the bottom of lateral openings guide groove 16a on its one side, guide groove supporting arm 20a, and the height of 20b can hold two cables or flexible pipe shoulder to shoulder.
The chain 54 that articulated links constitutes comprises the chain link (not showing hanger 50) that Fig. 1-3 describes, and is particularly suitable for various cables and similar pipeline that protection links to each other with coal winning machine 46 (Fig. 4), and coal winning machine uses in the coal mining activity face of broadwall face.The feedway of such coal winning machine 46 has an armoring face that couples together, and provides overflow plate delivery chute 48 to hold cable and similar pipeline.Some section of the protection chain 54 that the seesawing of coal winning machine 46 crosscut coal mining activity faces can make cable and similar pipeline is rolled into ring and unclamps.Each articulated links comprises the chain link of Fig. 1-3, and it can allow to be rolled into like this situation that ring unclamps again then as schematically illustrating among Fig. 5.
Suspension ring 50 can be used for articulated link chain was hung the crown, for example sling with chain or rope.
Each guide groove 20-26 is having constant width from web 10 to the whole height of the inlet of guide groove separately, thereby provides enough stability when whole chain back rolls.Not enough as stability, the strength of the dilatory whole chain of coal winning machine is got up with the weight combinations of cable and similar pipeline, will destroy the state of original alignment, thereby chain is twisted, and is out of hand, causes that each pipeline throws off from link.To be link design that enough robustnesses are arranged, being used for to keep large-sized cable and similar pipeline when underground, and need be designed to avoid damaging cable and similar pipeline to jut.The cross section of supporting arm and described nylon material not only will increase the chain link impact and cause damaged resistivity, but also will increase flexible to improve the insertion of cable and flexible pipe.The sharp edge number that can damage cable and flexible pipe is also reduced in the supporting arm cross section.
