Abstract
Unidirectionally vibrating hydraulic tamper.The present invention is used for the m of w operation and makes pillow railway ballast down firm by ramming.The vibrating device of tamping tool adopts two eccentric shafts, by gear drive, does the constant speed backward rotation each other, and the vibration component of two eccentric shaft horizontal directions is cancelled out each other.Formed the single vibration device that has only the vertical vibration force.Thereby make the hydraulic tamping machine stable working, energy loss is few, and power consumption descends, and improve application life.
Description
The present invention is a kind of hydraulic tamping machine tool that ballast aggregate under the pillow is made in the m of w operation firm by ramming that is used for.
In the railway maintenance machinery, the hydraulic tamping machine of existing various models, its vibrating device all be at the two ends of a vibrating shaft by the dress eccentric block, the centrifugal force of eccentric block is vibration force, this vibration force, the component of its vertical can pass to the pick palm effectively; But the vibration component of horizontal direction is quite different, because in vertical, distance between the pick of vibrating shaft and the pick plate lower end palm is five times of distance between vibrating shaft and the shock absorber, so can only having sixth to pass, slaps the vibration component of eccentric block horizontal direction to pick, again because shock absorber is a flexible member, the vibration component of the therefore actual horizontal direction that can pass to the pick palm is just littler.Role is inappreciable in the real vibration processes of the folder of hydraulic tamping machine.It is the horizontal rocking vibration of fulcrum that yet this power causes whole vibrating device to do with the pick plate lower end pick palm, and causes the vibration of one section section of track, and its energy loss is very big.The vibration component of horizontal direction has 5/6ths to affact on the shock absorber in addition, though through the shock absorber vibration damping, but still have quite a few to be delivered on the fuel tank, make whole hydraulic tamping machine also produce to a certain degree horizontal rocking vibration, not only cause energy loss, and making the easy shear failure of shock absorber, machine reduces application life.This vibrating device is owing to structural restriction, and the application life of vibrating shaft bearing is very low, has become the technology weak link of hydraulic tamping machine.
The objective of the invention is: eliminate the vibration component of the horizontal direction of hydraulic tamping machine vibrating device, make its stable working, reduce energy loss, reduce power consumption, improve application life.
Technical scheme of the present invention is: vibrating device adopts two eccentric shafts, by gear drive, does the constant speed backward rotation each other the vibration component of two eccentric shaft horizontal directions is cancelled out each other.Thereby constitute the unidirectionally vibrating hydraulic tamper that has only the vertical vibration force.
Characteristics of the present invention are: the unidirectionally vibrating hydraulic tamper stable working, and energy loss is few, and power consumption reduces, and improve application life.The vibrating device of the hydraulic tamping machine of its vibrating device and other model all has interchangeability, and since structural improvement, the application life of having improved the vibrating shaft bearing.
Fig. 1 is the right view of unidirectionally vibrating hydraulic tamper
Fig. 2 is the vertical view of single vibration device
Fig. 3 is the front elevation drawing of single vibration device
Fig. 4 is the N-N generalized section of single vibration device
Optimum implementation of the present invention is: as Fig. 1, the unidirectionally vibrating hydraulic tamper that is constituted by single vibration device (1), fuel tank (2), machine driven system (3), motor (4), frame (5), hydraulic system (6), pick plate (7), walking frame (8), except that single vibration device (1), all the other use XYD-2 type hydraulic tamping machine spare entirely.
The vibration frame (9) of single vibration device (1), its vibrating shaft dead eye is that axial line is parallel to each other, equal-sized two holes, upper cover plate is provided with the gear pilot hole, material therefor and identical with the vibrating device of the fitted position of fuel tank, pick plate and XYD-2 type hydraulic tamping machine.
Eccentric shaft (12) is packed into by the dead eye of vibration frame (9) and is connected cooperation with the gear of putting into from the gear pilot hole (13) by key (29), and the eccentric shaft overhanging end is by fixing direction assembling.As shown in Figure 1.Gear outside dress positioning sleeve (15).Then from eccentric shaft two ends dress oil baffle disc (14), bearing (16).Bearing cover (25) is loaded onto oil sealing (30) earlier, add adjusting pad (20) again, be pressed in then on the bearing of eccentric shaft overhanging end, after bearing cover (19) adds adjusting pad (20), be pressed on the bearing of the eccentric shaft other end, use bolt (17), spring washer (18) that the two bearings lid is fixed on the vibration frame at last.
Eccentric shaft (10) is packed into from another dead eye of vibration frame (9), is connected cooperation with the gear of putting into from the gear pilot hole (11) by key (29), will guarantee the identical by the position of pretending of two eccentric shafts during two gears engaged, as shown in Figure 3.Gear outside dress positioning sleeve (15), again from eccentric shaft two ends dress oil baffle disc (14), bearing (16), use bearing cover (19) to add adjusting pad (20) then, be pressed in the outside of two bearings, use bolt (17), spring washer (18) that the two bearings lid is fixed on the vibration frame again.
Belt pulley (26) is linked and packed at the overhanging end of eccentric shaft (12) by key (29), uses floor clip (27), garden nut (28) locking fixing again.Assembling port lid (22) adds paper washer (21) and is fixed on the upper cover plate of vibration frame (9) with bolt (23), spring washer (24).
Eccentric shaft (10,12), gear (13) material are steel No. 45, and gear (11) material is a nylon, and oil baffle disc (14), gear assembling port lid (22) material are aluminium sheet, and positioning sleeve (15) material is A
3Steel, bearing (16) model is 46406, and bearing cover (19), bearing cover (25), belt pulley (26) material are cast iron, adjusting pad (20), paper washer (21) material and are industrial paper, bolt (17,23), spring washer (18,24), floor clip (27), garden nut (28), key (29), oil sealing (30) and are standard component.
