Abstract
The utility model relates to a small hydraulic railroad-switch sand rammer, which is a railroad-switch sleeper tamping machine used by railroad workers and worker in a major repair department. The utility model is developed after the problems that a tamping device is divided into two devices, each device can move along the direction of a sleeper, and a rail clamping device can clamp a rail on a railroad switch when the size of the rail changes are solved. The utility model is characterized in that the lower surface of an oil tank is provided with a transverse moving device which is composed of a telescopic shaft, a transverse moving oil cylinder and a transitional shaft and a hanging box, the lower surface of the hanging box is connected with a separation type shock ramming device by a rubber shock absorber, the rail clamping device is composed of a rail clamping oil cylinder, a rack, a gear and a sliding rod mechanism of a crank, and the rail the bottom surface of which is in a range of 150 mm-440 mm can be reliably clamped. The utility model is an ideal machine for maintaining the railroad-switch sleeper.
Description
The utility model is the switch sleeper tamping machine that railway and overhaul department use.
In order on switch sleeper, to finish tamping operation, require the tamping pickaxe leg of tamping tool to do slotting under the vibrating type, the real action of vibrating type folder in the zone required the making firm by ramming of track switch.A kind of known small-sized hydraulic railroad switch tamping tool is arranged, and its four cantilevered axle that hang tamping pickaxe are the piston rod of four hydraulic cylinders, be used for driving tamping pickaxe and insert, press from both sides the real industry position of doing under the adjustment in track switch is laterally made the zone firm by ramming.The work of this hydraulic switches tamping tool is unreliable, the life-span short, and particularly operation effectiveness is bad.Also have a kind of can not doing after the insertion railway roadbed at its tamping pickaxe of vibrating type tamping tool of switch sleeper tamping operation to make the real action of folder that the ballast aggregate operation must have firm by ramming in addition, operation effectiveness is undesirable.
Task of the present utility model provide a kind of safe and reliable, operation effectiveness good, road small-sized hydraulic railroad switch tamping tool easily up and down.Its tamping pickaxe leg can be under the driving of the sideslip oil cylinder of separate type vibrating bin, makes firm by ramming in the zone in that track switch is required, and the adjustment of position is laterally made on road along the line at any time, and under the effect of hoist cylinder, finishes down and insert, promote and move.Under the effect of consolidated oil jar, finish the action of folder quarrel.When this machine during at tamping operation, rail clamping device hooks and clamps rail.
The utility model comprises: frame, hoist cylinder, tamping equipment, consolidated oil jar, transmission system, oil cylinder, rail clamping device and Traverse Displacement Unit.The Traverse Displacement Unit that it is characterized in that being installed in below the fuel tank is made up of telescopic shaft, sideslip oil cylinder, transition axis and suspension basket, the below that is fixed on fuel tank that the cylinder body of the spline housing of the overcoat of two telescopic shafts, transition axis and sideslip oil cylinder is parallel to each other with ring iron and screw, and the sleeve two ends of the piston rod of the splined shaft of transition axis, sideslip oil cylinder and telescopic shaft are connected with suspension basket respectively, are connected with the separate type tamping equipment with rubber shock absorber below the suspension basket.In the course of work, sideslip oil cylinder drives suspension basket and the separate type tamping equipment laterally moves along the sleeper direction, at this moment telescopic shaft and transition axis are also flexible thereupon, telescopic shaft is born in the course of the work the bending load by tamping equipment, rubber shock absorber passed over, transition axis is then by the V-belt transmission, the moment of torsion of motor is passed to eccentric iron on the tamping equipment, produce vibration; Bottom in frame is provided with rail clamping device, and it is made up of folder cylinder of rail, tooth bar, gear, plane slide crank linkage and spring.Tooth bar is fixed on the piston rod, and when piston rod contracts when stretching, tooth bar moves up and down thereupon, and driven gear rotates, and crank and gear are to be fixed on the same axis, drive the slide crank linkage simultaneously, hook plate is clamped and unclamps rail.
The utility model effectively solved the separate type tamping equipment separately can the sleeper direction laterally move and rail clamping device in rail foot surface is of a size of 150mm～440mm scope, a problem such as safe and reliable clamping rail is implemented in and uses machinery to carry out the vibrating type tamping operation on the track switch circuit.Improved the quality that the track switch mastery is protected, improved labor productivity, alleviated working strength of workers and improved condition of labor.
The utility model is provided by the following drawings and embodiment
Fig. 1 is the front view of small-sized hydraulic railroad switch tamping tool.
Fig. 2 is the lateral view of small-sized hydraulic railroad switch tamping tool.
Fig. 3 is the Traverse Displacement Unit half-sectional view.
Fig. 4 is the front view of rail clamping device.
In the utility model small-sized hydraulic railroad switch tamping tool, the piston rod of hoist cylinder (2) is installed on the crossbeam of frame (1) by ball pivot, the cylinder body of hoist cylinder (2) is then hinged by battle pin and fuel tank (3), motor is installed above the fuel tank, oil pump and hydraulically operated valve, fuel tank (3) two ends are connected with the guide pillar of frame (1) with axle sleeve, fuel tank (3) is under the drive of hoist cylinder (2), move up and down along guide pillar, below fuel tank (3), use ring iron and screw overcoat with two telescopic shafts (5-4) in the Traverse Displacement Unit (5), on the fuel tank regularly (3) that the cylinder body of the spline housing of transition axis (5-2) and sideslip oil cylinder (5-3) is parallel to each other, the splined shaft of transition axis (5-2), the sleeve of the piston rod of sideslip oil cylinder (5-3) and telescopic shaft (5-4) is connected with suspension basket (5-1) respectively, two suspension baskets (5-1) symmetry splits both sides below fuel tank, suspension basket (5-1) is connected with the separate type tamping equipment by rubber shock absorber (6), consolidated oil jar (4) is connected with pick plate (9) on being suspended on separate type tamping equipment (7) with nylon Xiao cover and bolt, be provided with rail clamping device (8) in the bottom of frame (1), it is by folder cylinder of rail (8-1), be fixed on the tooth bar (8-2) on the piston rod, gear (8-3), slide crank linkage (8-4) and spring (8-5) are formed.The crank of gear (8-3), slide crank linkage (8-4) is fixed on the same axle.The utility model has solved tamping equipment (7) has been separated, each self energy laterally moves along the sleeper direction, and rail clamping device (8) clamps rail in rail foot surface is of a size of 150mm～440mm scope, and has self-centering and centering function, satisfies the needs that switch sleeper is made firm by ramming.
