Abstract

A high-strength wear-resistant load-bearing type steel drag chain comprises thickened chain plates and two drag chain belts formed by connecting two thin chain plates end to end. A plurality of supporting plates are vertically mounted between the two drag chain belts, and arc-shaped dowel moving slotted holes are arranged on two sides of each thickened chain plate. The high-strength wear-resistant load-bearing type steel drag chain is characterized in that four or more arc-shaped dowel moving slotted holes 3 are respectively arranged on two sides of each thickened chain plate 1, one or a plurality of supporting rods 11 or supporting plates 12 are respectively mounted at the upper end and the lower end between each thickened chain plate 1 and a double-thin chain plate 2, so that a plurality of pairs of supporting points are formed on each chain plate, and a plurality of rectangular structures are formed. The area of the chain plates is increased, and the supporting rods or supporting plates are respectively mounted at the upper ends and the lower ends among the thickened chain plates and the double-thin chain plates, thereby greatly increasing supporting density, further strengthening the strength of the drag chain, and accordingly being capable of ensuring long service life and reliable operation of the drag chain under conditions of loading ultra-large-sized heavy loads.

Description

High-strength wearable weight bearing type steel drag chain

Technical field

The utility model relates to steel drag chain equipment and technology application, particularly a kind of high-strength wearable weight bearing type steel drag chain.

Background technique

On heavy mechanical equipment; often have that more motion is electric, the pipeline and the cable of hydraulic pressure, multiple gases, instrument distribution; for pipeline and the cable of protecting these motions; often they are placed on the large-sized steel drag chain and operate, every meter drag chain load-bearing will be added the weight of steel drag chain self above 130 kilograms like this; be subjected to heavy excessive; cause between the pivot pin pressurized excessive, and then strengthen the wearing and tearing of steel drag chain, shorten working life.The conventional connecting means of steel drag chain at present is to adopt the pivot pin both sides to process a draw-in groove respectively, blocks the location by jump ring.This joining method processing is simple, easy to loading and unloading, but because the degree of depth of the draw-in groove position of standard jump ring and pivot pin is limited, when drag chain self stressed when excessive, occur fluctuation when causing drag chain to move, through long period work, each parts of drag chain all have wearing and tearing in various degree.In this case, the release failure of jump ring and pivot pin taking place easily, cause drag chain not work, damage pipeline or cable on the machinery when situation is serious, causes irremediable economic loss to equipment.

Summary of the invention

The purpose of this utility model provides a kind of rational in infrastructure, wear-resisting, weight bearing type steel drag chain.

The purpose of this utility model is achieved in that a kind of rational in infrastructure, wear-resisting, weight bearing type steel drag chain comprises thickening carrier bar and two two drag chain bands that thin carrier bar end-to-end forms, be vertically installed with strut or dunnage between the two drag chain bands, place, thickening carrier bar both sides has the pivot pin arc slotted eye that moves about, and it is characterized in that: be provided with four or more bearing pin arc slotted eye 3 that moves about respectively at place, thickening carrier bar 1 both sides; Middle upper and lower end at every joint thickening carrier bar 1 and two thin plate carrier bars 2 is installed dunnage 12 respectively, and it is many to the strong point that each pitch chain plate is formed, and constitutes a plurality of rectangular configuration.

Two thin carrier bars 2 are set link to each other with place, thickening carrier bar 1 both sides, described two thin carrier bars 2 flexibly connect through pivot pin 13 with the thickening carrier bar 1 that is clipped in wherein; Also be connected through bolt and spacers are parallel between the two thin carrier bars 2.

Described thickening carrier bar 2 and two thin carrier bar 1 adopt 20MnSi steel or SUS304 stainless steel to make.Pivot pin 13 adopts solid brass bar to make.

The beneficial effects of the utility model are: rational in infrastructure, connect the release failure that jump ring and pivot pin firmly, steadily, can not take place between the carrier bar; Place, every joint thickening carrier bar both sides is provided with four or more bearing pin arc slotted eye that moves about respectively, made it to increase the area of carrier bar, kept original join strength, simultaneously, middle upper and lower end at every joint thickening carrier bar and two thin carrier bars is installed dunnage respectively, greatly increased support density, and then drag chain intensity is further strengthened; Pivot pin 13 adopts copper rod to make, and has wear-resisting characteristics according to brass, so also strengthened the wear resistance of drag chain, can guarantee that so the steel drag chain can be at super sized type heavy load following long lifetime of situation reliably working.

Embodiment

The utility model is described in further detail to engage accompanying drawing below: among Fig. 1, be provided with four or more pivot pin arc slotted eye 3 that moves about respectively at place, thickening carrier bar 1 both sides, center positioning hole 4, be provided with a plurality of struts and dunnage attachment hole 5 at thickening carrier bar 1 middle part, 6. supporting respectively four or more bearing pin attachment hole 7 that is provided with is located in the both sides of thin carrier bar (two plate) 2 among Fig. 2, center positioning hole 8, central part at thin carrier bar (two plate) 2 is provided with bolt connecting hole 9, spacers hole 10. is as Fig. 3, shown in 4, on the centre of every joint thickening carrier bar 1 and two thin plate carrier bars 2, the lower end is by strut or dunnage attachment hole 5,6 install one or more strut 11 or dunnage 12 respectively, it is many to the strong point that each pitch chain plate is formed, and constitutes a plurality of rectangular configuration.There is not burr with the carrier bar of Laser cutting and the bearing pin arc slotted eye that moves about, highly polished, the hardness height, its tangent plane is vertical with the plane, thereby increased the move about surface of contact of slotted eye 3 and bearing pin 13 of arc, its initial wear amount is reduced, effectively controlled the sagging of drag chain unsettled section.Compare with other steel drag chain, this reality has novel said drag chain structure more reasonable, is a kind of high-strength wearable weight bearing type structure drag chain, but at carrying long lifetime reliably working during heavy load.
