Control mine car makees back and forth movement on mine rail, and the transport to personnel, ore etc. is completed with this.Traditional connector
For loop chain type connector, connection is completed by coordinating with latch, it does not have the function of buffering collision of closed.Since conventional rails are transported
Mine car is made of wheel, mine car car body, itself does not simultaneously have brake apparatus, and mine car is in climb and fall or parking due to front and rear ore deposit
Vehicle speed can be inconsistent, easily collides between mine car, due to being connected using traditional connector, the impact force between mine car
Not by snubber, rigid collision directly occurs between mine car.Particularly mine car full load, the collision between mine car easily lead to ore deposit
Car deformation, overturning and damage etc., increase production maintenance cost.
For hydraulic cylinder as the common execution unit of Hydraulic Field, it generally comprises piston, piston rod, cylinder body and sealing device
Deng piston is connected with piston rod, and piston rod is extended to outside cylinder body, and piston is installed in cylinder body and hydraulic cylinder is divided into two chambers
Body, tailpiece of the piston rod are rod chamber, and the other end is rodless cavity.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of prevent mine car rigid collision have double buffering make
Mine car buffer coupling.
The technical solution adopted by the present invention to solve the technical problems is：Mine car buffer coupling, it includes hydraulic cylinder, storage
Fuel tank, buffer spring, spring bearer plate, lock nut, latch connection end and one-way throttle valve；The rod chamber of the hydraulic cylinder is straight
Logical fuel reserve tank, the rod chamber of the hydraulic cylinder and the rodless cavity of hydraulic cylinder by equipped with drainback passage communicate with each other；The list
Drainback passage is arranged to throttle valve, and one-way throttle direction is：Hydraulic cylinder rodless cavity flows to hydraulic cylinder rod chamber；The buffering
Spring pocket is on the piston rod of hydraulic cylinder；The latch connection end is equipped with external thread rod；The latch connection end passes through
The piston rod thread of external thread rod and hydraulic cylinder connects；The spring bearer plate end face is equipped with through hole, and the spring bearer plate passes through logical
Hole is sleeved on external thread rod, and the lock nut is connected with external thread rod and is located on the outside of spring bearer plate.
Further, the spring bearer plate end face is equipped with first boss, and the hole wall of the through hole is equipped with second boss；It is described
Hydraulic cylinder) piston rod be equipped with first boss match the first groove；The external thread rod is equipped with what is matched with second boss
Second groove.
Further, the latch connection end is provided with radial bearing.
The beneficial effects of the invention are as follows：The mine car buffer coupling of the present invention, when connected mine car will collide, mine car below
Piston rod, piston motion are promoted, makes spring bearer plate compression compression spring, compression spring provides a part of mine car of counterforce counteraction
Impact force, meanwhile, hydraulic cylinder rodless cavity fluid is pressurized, and by the throttling action of throttle orifice, provides piston part damping again
A part of mine car collision impact is absorbed, anticollision effect is good, can effectively avoid mine car collision deformation.Spring bearer plate is equipped with first
Boss and second boss and respectively with the first groove, the second recess, can be effective by clamp nut holddown spring pressing plate
Locking latch connection end, prevents its loosening from dropping, and sport car, coaster accident occurs.

Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in Figures 1 to 4, mine car buffer coupling, it includes hydraulic cylinder 1, fuel reserve tank 2, buffer spring 4, spring pressure
Plate 5, lock nut 6, latch connection end 7 and one-way throttle valve 9；The rod chamber of the hydraulic cylinder 1 leads directly to fuel reserve tank 2, described
The rodless cavity of the rod chamber of hydraulic cylinder 1 and hydraulic cylinder 1 by equipped with drainback passage 8 communicate with each other；The one-way throttle valve 9 is set
Drainback passage 8 is placed in, and one-way throttle direction is：The rodless cavity of hydraulic cylinder 1 flows to the rod chamber of hydraulic cylinder 1；The buffering elastic
Spring 4 is sleeved on the piston rod of hydraulic cylinder 1；The latch connection end 7 is equipped with external thread rod 71；The latch connection end 7
It is connected by external thread rod 71 with the piston rod thread of hydraulic cylinder 1；5 end face of spring bearer plate is equipped with through hole 51, the spring
Pressing plate 5 is sleeved on external thread rod 71 by through hole 51, and the lock nut 6 is connected with external thread rod 71 and is located at spring bearer plate
5 outsides.
Fuel reserve tank 2, drainback passage 8 and one-way throttle valve 9 can be integrated in the cylinder body of hydraulic cylinder 1, can be also separately provided.Work
Fill principle：Mine car buffer coupling is installed on mine car afterbody, latch and an other mine car are inserted by latch connection end 7
Connection, when front and rear mine car will collide, mine car below can promote the piston rod of hydraulic cylinder 1 and piston to move, so that
Buffer spring 4 provides reaction force by compression, offsets a part of impact force.The piston rod and piston of hydraulic cylinder 1 move at the same time, liquid
The rodless cavity volume of cylinder pressure 1 reduces, and fluid is discharged into the rod chamber of hydraulic cylinder 1, unnecessary fluid through one-way throttle valve 9, asphalt channel 8
Fuel reserve tank is discharged into by the rod chamber of hydraulic cylinder 1, during oil extraction, by the throttling action of one-way throttle valve, the piston of hydraulic cylinder 1 and
Piston rod is dampened to reabsorb a part of impact force, slows down collision.Mine car buffer coupling, double buffering effect, than simple
Spring buffer effect is good, can effectively reduce mine car particularly mine car full load, collision deformation between mine car etc..
In use, mine car sport car, car slipping thing occur latch connection end 7 for the automatic loose or dislocation of stress in order to prevent
Therefore further 5 end face of spring bearer plate is equipped with first boss 53, the hole wall of the through hole 51 of the spring bearer plate 5 is equipped with the
Two boss 52；The piston rod of the hydraulic cylinder 1 is equipped with the first groove to match with first boss 53；The external thread rod 71 is equipped with
The second groove to match with second boss 52.In use, lock nut 6, spring bearer plate 5 are first sleeved on external thread rod 71 successively
On, second boss 52 is caught in the second groove 711 at this time, then external thread rod 71 is screwed in the piston rod certain depth of hydraulic cylinder 1, moves
Dynamic spring bearer plate 5 makes first boss be caught in the first groove, screws locknut nut 6 and locks, can effectively prevent latch connection end 7
Loosen.
For the ease of traction of the jink to mine car, the latch connection end 7 is provided with radial bearing 72.
