Description
Technical field
The utility model belongs to hump yard car retarder apparatus field, more particularly, to a kind of electro-hydraulic decelerator.
Background technology
At present, two bases of electro-hydraulic decelerator are to be coordinated by intermediate connector end face after fixed be rigidly connected together,
Increase the reliability that electro-hydraulic decelerator is used.Oil cylinder develops with hydraulic technique, and an overhaul time typically can be used in oil cylinder
(8 years), but oil-proof failure interior during use can not be completely secured, so, oil cylinder needs demolition and maintenance unavoidably.But oil cylinder
Between two connectors, on two type concrete slab sleepers below plane, connector must be removed when changing oil cylinder, could more be changed oil
Cylinder.If electro-hydraulic decelerator is pacified between common spacing concrete slab sleeper, dismounting connector is all inconvenient.Therefore, electro-hydraulic decelerator base is not
Obtain and used not as II type sleeper.
Electro-hydraulic decelerator, which has problem, in summary is：1st, electro-hydraulic decelerator base needs to use as II type sleeper,
Domestic electro-hydraulic decelerator, which belongs to railway communication signal, to be responsible for, and sleeper safeguards that belonging to works department is responsible for, and new design equipment is in condition
Possess work business as far as possible and electricity business equipment to separate；2nd, oil cylinder is on II type sleeper below plane, and dismounting oil cylinder is inconvenient, dismounting
Oil cylinder needs to dismantle intermediate connector, wastes time and energy, is unfavorable for the requirement of railway equipment rapidly removing faults；3rd, intermediate connector
Coordinate with base end face and fix, occupancy station track space is big, it is necessary to which concrete slab sleeper spacing is big, and the single carrying of work business concrete slab sleeper increases, shadow
Ring its service life；4th, intermediate connector and base end face are bolted, and bolt looseness can influence fixed reliability；
5th, the relatively basic rail of transmission mechanism rod member is too deep, and the draining of Some Domestic marshalling yard is poor, the easy bubble of axle sleeve, influences its service life.
Electro-hydraulic decelerator uses double fastener flat push type arrestment mechanism, and single cylinder arrestment mechanism, structure is novel, advanced technology, technology
It is practical, it is pioneering both at home and abroad.But there is problem above, if solution is bad, influence product promotion is used, therefore, research one
Plant new structure solution problem above very necessary.

Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1, 2, a kind of electro-hydraulic decelerator, including base 1, braking rail chair 2, connecting plate 12, crank throw 9, connecting rod 10,
Braking rail 6 and oil cylinder 14, two bases 1 are secured together by two connecting plates 12, and two connecting plates 12 are located at two bottoms respectively
The front and rear sides located between seat 1, oil cylinder 14 is connected to the top of base 1 by oil cylinder axle 21, and the piston rod at the two ends of oil cylinder 14 leads to
Cross connecting rod 10 and be connected to crank throw 9.
The braking rail 6 is fixed on braking rail chair 2 by fixing bolt 7 and nut 4, and fixing bolt 7 is located at braking
The both sides of rail chair 2, crank throw 9 is connected on base 1 by upper crank shaft 5 and lower crank shaft 8, and the top 3 of crank throw is close to braking rail
The upper end of seat 2, the bottom 19 of braking rail chair, which is embedded on the inner side on the top 20 of base, such crank throw 9, to be used for through crank shaft
The length of axis hole can just shorten.
Fixed, and fastened with splined nut 11, the company by bolt axle 13 between the connecting plate 12 and each base 1
The both sides of fishplate bar 12 are respectively provided with 4 bolt axles 13.Locking split pin 22 is installed between the splined nut 11 and bolt axle 13.Often
Individual bolt axle 13 is sequentially passed through in connecting plate 12, base 1, connecting plate 12, splined nut 11 and locking split pin 22.
The oil cylinder axle 21 is located on connecting plate 12, and the junction of oil cylinder axle 21 and connecting rod 10 also is located at connecting plate 12
On.
Improved by above structure design, the oil cylinder axle 21 of oil cylinder 14 out of connecting plate 12 on move on on connecting plate 12,
Also on concrete slab sleeper more than plane, oil cylinder axle 21 is in the case where that need not dismantle connecting plate 12 with regard to detachable oil cylinder 14.Improve
Afterwards, connecting rod 10 is also shifted up, close to the stock rail flange of rail, to preventing rainwater immersed with certain adaptability, has also allowed for maintenance
Change.
Two bases 1 of new electro-hydraulic decelerator are secured together by two connecting plates 12, connecting plate 12 and each bottom
Fixed form passes through rigid shaft hole matching to fix by two or more bolt axle 13 between seat 1, is then fastened with splined nut 11
Locking split pin 22 is put on to together, and in splined nut 11 and bolt axle 13.Wherein, the hole of bolt axle 13 and connecting plate 12 and
The hole of base 1 is all to coordinate to install, and gap value is very small, due to being two or more bolt axle 13, between connecting plate 12 and base 1
Also it is not present and rotates, so as to reaches the purpose rigidly fixed.Bolt axle 13 undertakes main stress, and bolt axle 13 sequentially passes through connection
Plate 12, base 1, connecting plate 12, splined nut 11 and split pin 22.So two sides connecting plate 12 passes through bolt axle 13 and trough of belt spiral shell
Mother 11 fastens, and connecting plate 12 is tightly pressed against to the two sides of base 1, bolt axle 13 and the bolt pretightening of splined nut 11, even
Just there is certain frictional force between fishplate bar 12 and base 1, also just share a part of shearing force of bolt axle 13, add base 1
Rigidly fixed between connecting plate 12, so that rigidly fixing for two relative positions of base 1 is strengthened, even if without frictional force,
Two bases 1 can be also rigidly connected together by new design connected mode.This programme is actual when implementing, connecting plate 12 and each bottom
Between seat 1 it is rigidly fixed to together by 4 bolt axles 13.After so fixing, occupancy station track space is small, and reliability is high.
The preferred embodiment of the utility model creation is the foregoing is only, not to limit the utility model wound
Make, within all spirit created in the utility model and principle, any modification, equivalent substitution and improvements made etc. all should be included
Within the protection domain that the utility model is created.
