Description
Technical field
The present invention relates to a kind of rail vehicle Parking Brake Cylinders hand relieving drag-lines.
Background technique
When needing hand relieving under parking brake state on current track vehicle, artificial pull is widely used and is located at vehicle
The drag-line of two sides position easy to operate releases parking brake.Existing rail vehicle Parking Brake Cylinders hand relieving includes drawing with drag-line
Slidable drag-line steel wire is arranged in cable sleeve in noose pipe, and cable sleeve both ends are equipped with cable connector, and the two of drag-line steel wire
End is pierced by outside cable connector, and drag-line steel wire both ends are equipped with wire joint, and cable sleeve includes the liner being sleeved on outside drag-line steel wire
And it is wrapped in the outer tube outside liner.The handle end of drag-line is mounted on vehicle body side, and the other end is connected in Parking Brake Cylinders,
Intermediate bands part is hung on bogie by band.It is found in practice, existing rail vehicle Parking Brake Cylinders hand
Dynamic to alleviate drag-line when in use, required alleviation power is excessive, can not usually pull, and finally results in stopping brake and is difficult to alleviate.Alleviate
The excessive reason of power is more, and the frictional resistance between cable core and internal lining pipe is excessive, drag-line is bent excessively serious, drag-line elasticity not
Ideal is all to cause to alleviate the big reason of power.
Summary of the invention
It is required to alleviate the small rail vehicle parking brake of power when it is an object of the invention to propose that a kind of hand brake is alleviated
Cylinder hand relieving drag-line.
In order to achieve the above objectives, the present invention adopts the following technical scheme that: rail vehicle Parking Brake Cylinders hand relieving drag-line
Including drag-line steel wire, cable sleeve, card slot connector and nipple, drag-line steel wire includes steel wire cable core, and cable sleeve includes interior
Bushing pipe and outer tube, the drag-line steel wire further include coated in the film layer on hawser core outer surface；The cable sleeve is also
Including outside being coated on steel wire floor outside internal lining pipe, being wrapped in steel wire floor and for spiral helicine band steel layer and being wrapped in strip
The outer tube outside layer, drag-line steel wire can slide in internal lining pipe, and cable sleeve is stretched out at its both ends；In card slot connector
Equally have with the connecting hole and pilot hole on the same straight line, in nipple connecting hole on same straight line and
Pilot hole, is equipped with internal lining pipe in two pilot holes, and in the connecting hole of one end insertion card slot connector of cable sleeve, drag-line steel wire is logical
The internal lining pipe for crossing card slot connector is protruding, and in the connecting hole of the other end insertion nipple of cable sleeve, drag-line steel wire is logical
The internal lining pipe for crossing nipple is protruding.
The connecting hole of the card slot connector is the stepped hole with large and small diameter hole, diameter holes and the pilot hole phase of stepped hole
It connects, one end that cable sleeve is connect with card slot connector removes one section of outer tube, exposure band steel layer, the large diameter hole and drawing of card slot connector
Noose pipe tight fit, the diameter holes of cable sleeve and the band steel layer tight fit of exposure.
It is connected between the diameter holes and pilot hole of the card slot connector for the conical surface, formation taper type space, in card slot connector
One end of internal lining pipe there is taper type end with taper type spatial match, which is placed in the frustum of card slot connector
In shape space.
The connecting hole of the nipple is the stepped hole with large and small diameter hole, and diameter holes connect with pilot hole, drag-line set
It manages the one end connecting with nipple and removes one section of outer tube, with steel layer, the large diameter hole and cable sleeve of nipple are tight for exposure
Cooperation, the band steel layer tight fit of diameter holes and exposure.
It is connected between the diameter holes and pilot hole of the nipple for the conical surface, formation taper type space, in nipple
One end of internal lining pipe there is taper type end with taper type spatial match, which is placed in the frustum of nipple
In shape space.
One end that the steel wire cable core stretches out nipple is fixedly connected with pull rod；The head of pull rod is thread segment, screw thread
Section is connected with nut and recoil inserts.
The internal lining pipe is PTFE(polytetrafluoroethylene (PTFE)) material.
The steel wire floor combines steel wire using 65Mn.
The outer tube is TPEE (thermoplastic polyester elastomer) plastic cement material.
Film layer on the hawser core outer surface is PA1010(nylon 1010) coating.
The present invention has following good effect: 1) drag-line steel wire surface has coated nylon 1010 film layer, than existing steel wire
Directly reduce frictional resistance with liner contact slide；Internal lining pipe is PTFE(polytetrafluoroethylene (PTFE)) material, PTFE have high lubrication,
Low-friction coefficient performance, since the outer layer of drag-line steel wire is that PA1010 coating rubs when drag-line steel wire slides in PTFE internal lining pipe
Wiping resistance will be greatly reduced, and reduce alleviation power required when hand brake is alleviated；65Mn plying is coated with outside internal lining pipe
Steel wire floor, 65Mn alloyed steel elastic is good, improves the elasticity of drag-line entirety, advantageous drag-line it is straight, equally reduce manual system
Required alleviation power when dynamic alleviation, the present invention provide conveniently for stopping brake alleviation；2) increase band outside 65Mn plying steel wire floor
Steel layer reinforces steel wire floor, prevents steel wire floor in use because rupture causes to fail, while can reduce in use process
In shorten due to outer tube caused by inside and outside interacting.3) TPEE outer tube has the elastic and engineering plastics strong of rubber
Degree has excellent creep resistant and fatigue performance, even if in the case that bend ratio is more serious, being also avoided that due to steel wire strand
The phenomenon that housing caused by gathering cracks.4) internal lining pipe in card slot connector is placed in the frustum of card slot connector by taper type end
In shape space, the internal lining pipe in nipple is placed in the taper type space in nipple by taper type end, prevents two
Internal lining pipe in connector falls off, and can play position-limiting action to the internal lining pipe in outer tube.
