Description
Technical Field
The utility model relates to a rail anti-labyrinth damping parcel especially relates to a tram burys formula track anti-labyrinth damping parcel product.
Background
With the rapid development of urban rail transit, tramcars are developed in various cities in a falling mode more rapidly; meanwhile, people have higher requirements on the riding comfort of the vehicle. The urban rail transit brings convenience to people going out, and the wheel rail coupling vibration also brings vibration and noise pollution problems to surrounding buildings, and the particularity of the tramcar is that the rail system of the tramcar mostly adopts an embedded structure to ensure sharing of public road rights, and the embedded structure inevitably causes corrosion problems of steel rails, including vibration control of the steel rails, most importantly, the steel rails are used as return rails, after being embedded, the steel rails are insulated, difficulty in diversion treatment is prevented from increasing, and the existing products and technologies cannot effectively guarantee the steel rails.
The main measures at present comprise: the corrosion resistance and the insulating property of the cable are improved by adopting a non-metal fastener system; wrapping the steel rail by adopting a common rubber material; but its damping and insulating effect are mostly not ideal, and only a small part of construction quality is high can possess certain effect, but also mostly has some drawbacks, mainly reflects in: nonmetal fastener system can only improve the local insulating properties of track, but the unsettled setting in whole most positions of track, rail end and web parcel outside all backfill soil to set up the afforestation on it, the rainwater, moist very easily makes local insulating properties descend, the form that bonds behind the concatenation is mostly adopted to existing rail parcel material covers in the rail both sides, and what adopt basically to the rail is "three lamella formula" cover mode, rail end cover boots one lamella promptly, rail web inboard one lamella, rail web outside one lamella's form. The three parts are easy to generate leak or weak points on the interface in the splicing process, and finally cause the insulation performance of the system to be reduced, and even more, the local leak and the foundation or the ballast bed form rigid connection to cause the failure of the vibration damping performance; the steel rail wrapping material has high construction requirement and high construction difficulty, quality problems are easy to occur in the actual installation and construction process, and the performance of products cannot be effectively ensured; nonmetal improves the corrosion resistance and the insulativity, and the rubber material has poor vibration reduction and insulation effects.
SUMMERY OF THE UTILITY MODEL
In order to solve the not enough among the prior art, provide a leakproofness good, the equipment is convenient, the anti-labyrinth damping parcel structure that spare part is few, the utility model discloses the technical scheme who adopts is:
the utility model provides a tram track prevents damping parcel structure that tricks, includes left damping piece and right damping piece, left damping piece with rail one side web of a rail and one side rail end upper surface covering, right damping piece with rail opposite side web of a rail, another side rail end upper surface and rail end lower surface covering, left damping piece and right damping piece combination after with rail web of a rail and rail end full coverage, left damping piece and right damping piece are located the one end of rail end and are equipped with connector and the spread groove that can peg graft the combination together respectively left damping piece and right damping piece grafting position still be equipped with seal groove and sealed muscle respectively, sealed muscle can insert in the seal groove left damping piece and right damping piece be equipped with respectively along rail direction both ends and can the overlap joint cooperation be the link of step shape.
Furthermore, cavities are arranged on the contact surfaces of the left damping piece, the right damping piece and the rail web.
Furthermore, the length of the left damping part and the length of the right damping part covering the rail web part are both greater than the length of the right damping part covering the rail bottom part; and both ends of the left damping part and the right damping part are provided with notches facilitating the installation of the fasteners.
Furthermore, the connecting groove and the connector are in dovetail tenon structure connection.
Adopt the anti-labyrinth damping parcel of this structure, no longer set up the form of damping plate and the combination of rail end damping plate through rail web both sides, only need assemble through two damping parts and just can realize the total coverage to the rail, change traditional "three lamella formula" combination into the combination form of two and reduced spare part quantity, it is more convenient to assemble, it realizes sealedly to set up seal groove and sealed muscle cooperation at left damping part and right damping part connection position, and left damping part and right damping part realize connecting through the overlap joint along track length direction and have better sealed effect, improve anti-labyrinth effect.

Detailed Description
The anti-entrainment damping wrapping structure comprises a left damping member 1 and a right damping member 2 as shown in fig. 1 and fig. 2, wherein the left damping member 1 covers the rail web of the steel rail and the upper surface of the rail bottom on one side, the right damping member 2 covers the rest part of the rail web and the rail bottom on the other side, and the left damping member 1 and the right damping member 2 are combined together in an insertion mode to wrap the rail web and the rail bottom of the steel rail, so that the anti-entrainment and vibration reduction effects are achieved.
As shown in fig. 3, a connector 3 is arranged at one end of the left damping member 1, as shown in fig. 4, a connecting groove 4 is arranged at one end of the right damping member 2, which is located at the rail bottom, a left damping member 1 and a right damping member 2 are spliced and assembled together through the connector 3 and the connecting groove 4, so as to fully cover the rail web and the rail bottom of the steel rail, in this embodiment, a dovetail structure is adopted for connection, which is not limited to the connection form of the structure in practice, and the positions of the connector 3 and the connecting groove 4 can be exchanged, because the position needs to be connected but not integrally formed, the sealing problem needs to be solved, so that a sealing groove 5 and a sealing rib 6 are respectively arranged at the position where the left damping member 1 and the right damping member 2 are connected, and after the left damping member 1 and the right damping member 2 are connected through the connector 3 and the connecting groove. In order to save materials, the left damping part 1 and the right damping part 2 are provided with a cavity on one side contacting with the rail web, the cavity can save materials and reduce cost, the left damping part 1 and the right damping part 2 are enabled to have more deformation allowance, and the vibration reduction and noise reduction effects are improved.
The steel rail is long in length, and the steel rail cannot be completely covered by only one left damping part 1 and one right damping part 2, so that the whole steel rail needs to be protected by splicing and combining along the length direction of the steel rail, in order to achieve square splicing and combining, connecting ends 7 are arranged at two ends of the left damping part 1 and the right damping part 2 along the length direction of the steel rail respectively, the connecting ends 7 are steps and can achieve lap joint, the connecting ends 7 at two ends of the left damping part 1 can achieve lap joint in a matched mode, the connecting ends 7 at two ends of the right damping part 2 can also achieve lap joint in a matched mode, and therefore unified specification batch production can be achieved, and when the steel rail is spliced along the steel rail, two adjacent left damping parts 1 or two adjacent right damping parts 2 are connected together in a lap joint.
For the installation of fastener on the convenient rail, the length that left damping member 1 and right damping member 2 cover the web position all is greater than the length that covers the rail bottom position, sets up breach 9 at left damping member 1 and right damping member 2 both ends simultaneously and lets a position easy to assemble for the fastener.
