Background technology
Stabilising arrangement is one of groundwork device in the railway track mechanization maintenance machinery.Stabilising arrangement is exported horizontal exciting force through track and sleeper to the railway ballast under the sleeper; Thereby it is also further closely knit that railway ballast is arranged again; Applying downward pressure through the Vertical loading oil cylinder to the both sides rail more evenly sinks rail; And reach predetermined deflection, to satisfy railway track mechanization curing requirements.The vibration source of existing stabilising arrangement---vibrator is the twin shaft inertia vibration generator; It is the synchronous backward revolution through two eccentric shafts; Generation and the perpendicular straight line exciting force of diaxon line are accomplished vibration, when the eccentric mass of diaxon is in horizontal the same side, and the stack of the exciting force of diaxon; And when the eccentric mass of diaxon was in vertically opposite position, the exciting force of diaxon was then cancelled out each other.Therefore, existing stabilising arrangement exists power utilization low, and complex structure is to processing assembling problem such as have relatively high expectations.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, stable work in work, reliable, the horizontal linear inertia vibration generator that power utilization is high.
Technical scheme of the present invention is a kind of like this horizontal linear inertia vibration generator; Comprise casing, place the eccentric shaft on the casing, it is characterized in that being hung with excitor through elastic component in the casing; Be fixed with connecting rod on the excitor; The connecting rod other end links to each other with eccentric shaft, so that through the cooperating of eccentric shaft and connecting rod and excitor, the gyration of eccentric shaft is changed into the linear reciprocating motion of connecting rod and excitor; The inertia force that excitor produced with suspension passes to casing and makes its vibration through connecting rod, eccentric shaft again, thereby outwards exports the horizontal linear exciting force through the vibration of casing.
Said excitor middle part is provided with axis hole, and eccentric shaft passes this axis hole and places on the casing, does not produce with eccentric shaft when preventing excitor work anyly to contact or interfere each other.
Said excitor down either side is fixed with elastic component respectively, and the elastic component upper end all is fixed on the casing top, so that let excitor be suspended in the casing middle part.
Said connecting rod is made as two; Their end all is fixed on excitor leading flank and the trailing flank through the fixture symmetry; The other end is separately fixed on the rotor journal of the eccentric shaft that is positioned at the forward and backward side of excitor, so that do linear reciprocating motion through the rotation drivening rod and the excitor of eccentric shaft.
Said eccentric shaft front and back ends is installed on the casing through bearing, to make things convenient for the eccentric shaft rotation, casing is together vibrated with eccentric shaft.
The present invention compared with prior art has advantage and effect: adopt such scheme, promptly connect through less parts and comparatively simple structure, just can outwards export exciting force; Because the frictional resistance between each part is less; The conversion ratio of input power is improved largely, and can prolong its service life, help practicing thrift cost; Cut down the consumption of energy; As mechanical vibration source, can be widely used in railway maintenance with on tamping machine, the sieving machine, also can be applicable on other vibrating machine.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the present invention.
Horizontal linear inertia vibration generator provided by the invention is such: casing 1 is cuboid; Cuboid 1 middle part is hung with rectangle excitor 3; Specifically: the down either side of rectangle excitor 3 is fixed with spring 2 respectively; The upper end of two springs 2 all is fixed on casing 1 top, lets excitor 3 be suspended in casing 1 middle part, makes excitor 3 peripheries leave enough movement clearance with casing 1; Excitor 3 middle parts are provided with axis hole 31; Eccentric shaft 4 passes this axis hole 31 places on the casing 1 its two ends; Do not produce when preventing excitor 3 work and anyly contact or interfere each other with eccentric shaft 4; Be fixed with connecting rod 5 respectively through gudgeon 51 on the forward and backward two sides of excitor 3; The other end of two connecting rods 5 is fixed on the rotor journal 41 of the eccentric shaft 4 that is positioned at excitor 3 forward and backward sides through the axis hole on it respectively, so that do linear reciprocating motion through the rotation drivening rod 5 and the excitor 3 of eccentric shaft 4, the inertia force that excitor 3 produced with suspension passes to casing 1 and they are together vibrated through connecting rod 5, eccentric shaft 4 again; Thereby outwards export the horizontal linear exciting force through casing 1, like Fig. 1, Fig. 2.
