Abstract
The present invention provides a rail coupling device which comprises a reinforced clamping plate, four wedge blocks, a plurality of screw bolts and matched gaskets, wherein the screw bolts are arranged in two vertical rows, and the reinforced clamping plate is composed of a clamping plate, a base plate and ribs, so that the inertia moment of a cross-section horizontal shaft is greatly enlarged. Joint resistance is increased by using rotation tendency and the wedge blocks. The present invention has the advantages of strong buckling resistance of joints, strong joint resistance, light weight and small weakening effect to rails, and can lay and bolt continuous welded rails by using lower cost than laying traditional rails. The coupling device is especially suitable for laying and bolting continuous welded rails.
Description
Technical field
The present invention relates to the steel rail laying technical field, particularly the railway track joint technical field.
Background technology
The rail joint of conventional rails is with two splice bars and six roots of sensation Bolt Connection.Because the horizontal axis moment of inertia (two sums) of splice bar has only about 1/3 of rail, and joint resistance is not enough to stop expanding with heat and contract with cold of rail, must leave bigger shrinkage joint.So the continuity of joint rail is destroyed, mainly shows: aspects such as rail gap, knuckle.After the rail continuity was destroyed, when vehicle crossed, blank area was subjected to very big impact additional power effect.Can cause many connector area diseases, increase the workload of maintenance widely.
Ways of addressing this issue is to lay gapless track.On technical performance, the welding gapless track is best.But the cost of welding is higher, operation inconvenience.So, " frozen joint " and " bolt joint " appearred simultaneously." frozen joint " cut bolt, and safety is relatively poor.Existing " bolt joint " used bolt costliness is as 8 dollars/piece of Haake bolt present prices.And no matter as long as use splice bar, just there is horizontal axis bending resistance deficiency in which kind of blind joint, the problem of frangibility.The clamping plate steel using amount of binding foot is big, and the joint resistance of unit bolt tension force is little, if will be used for the bolt gapless track must use special high-strength bolt, cost is very high, and corner ruptures easily.Compare with the clamping plate of binding foot, the present invention has different mechanical models and form of structure.Bind foot the movement tendency of clamping plate under the bolt tension force effect based on slip, and the enhancing clamping plate among the present invention are based on rotation, again because the bolt arrangement difference has determined the mechanical model difference.In addition, the cleat plate waist of the clamping plate of binding foot is girder structures, and of the present invention be arch-type structure.
Technology contents
The objective of the invention is to provide a kind of coupling device for rail, and it can effectively increase joint resistance and joint bending resistance, thereby improves the overall performance of rail joint.
The purpose of invention can be achieved through the following technical solutions:
1. establish the enhancing base plate at the flange of rail, and clamping plate and the rib between them one each other, constitute and strengthen clamping plate, be down " " the word structure, the horizontal axis moment of inertia of joint cross section increased widely.
2. the contact counter-force application point of the upper and lower contact surface of clamping plate is having a spacing along design on the rail transverse horizontal direction.Make to strengthen the clamping plate trend that under the bolt tension force effect, rotates, thereby cause huge contact counter-force.The center line of cleat plate waist overlaps with pressure line, is a broken line, is arch structure.Two intercostals of rail gap homonymy, be provided with above the base plate one section horizontal domatic, form the wedge space with the flange of rail.The following contact surface of contract piece is domatic, and have on the contract piece one with domatic bolt hole in the same way, flange of rail bolt passes this screw, make contract piece contract go into above-mentioned wedge space, on the contact surface of contract piece and the flange of rail, produce the bigger normal pressure that contacts, also adjusted the contact normal pressure on the upper and lower contact surface of clamping plate simultaneously.And then the very big joint resistance of acquisition.
The invention has the advantages that: cross section horizontal axis moment of inertia is big, and joint resistance is big, and to the weakening of rail little (bolt hole on the web of the rail is few, and diameter is little), in light weight, steel using amount is few.The scope of application is big, can be used for the traditional railway circuit, also can be used for bolt gapless track and other rail track.

Embodiment
Embodiments of the invention are as follows: clamping plate 6 have base plate 8, with rib 7 one each other, be down " " the font structure, constitute and strengthen clamping plate 2.Rib 7 between clamping plate 6 and the base plate 8 can be four, also can be three, the root on rail gap both sides can be merged into a big rib, but so, with as the clamping plate of binding foot, and corner's easy fracture.Clamping plate 6 main effects are to clamp rail 1, and bear vertical shear and part bending normal stresses.The contact counter-force application point of the upper and lower contact surface of clamping plate 6 is along designing certain distance on the rail transverse horizontal direction, makes to strengthen clamping plate 2 trend that rotates under bolt 3,4 tension, thereby causes huge contact counter-force.For economical with materials, the center line of clamping plate 6 plate waists overlaps with pressure line, is broken line, is a pressure arch.The main effect that strengthens base plate 7 is the horizontal axis moment of inertia that increases cross section.Two intercostals of rail gap homonymy, be provided with above the base plate one section horizontal domatic 9, form the wedge space with the flange of rail.The following contact surface of contract piece 5 is domatic, and contract piece 5 have one with domatic bolt hole in the same way.Flange of rail bolt 4 passes this screw, and makes contract piece contract go into the wedge space of base plate and flange of rail formation under its tension, has further increased the contact normal pressure.Thereby obtain bigger joint resistance.Laterally domatic 9 and corresponding contract piece glide slope can be designed to a plane as required, also can be designed to " V " domatic.On " V " is domatic, coat lubrication oil, under identical flange of rail bolt 4 tension, the contract piece is enlarged markedly with the normal pressure that contacts of the flange of rail.
