Abstract
The utility model discloses a tamping pick with a torsional spring for power transmission, which comprises a handle, a driving device and a vibrating bar. A torsional spring is disposed between the driving device and the vibrating bar and supported in a sleeve through a bearing. Compared with the prior art, the tamping pick has the advantages that the driving device and the vibrating bar need no flexible shaft for connection, and conversely, the torsional sprig is used for connecting the driving device with the vibrating bar, so that the problems that the flexible shaft is short in service life and the flexible shaft bends and vibrates in rotation are solved.
Description
Technical field
The utility model relates to a kind of railway maintenance mechanical device, relates in particular to a kind of tamping pickaxe.
Background technology
In the prior art; Be used for small-sized tamping pickaxe that railroad ballast makes firm by ramming common have three kinds: (1) application number is called the device that utility model patent provided of " portable internal combustion high frequency tamping tool " for " 03245911.4 ", name; (2) application number is that " 200420010881.7 ", name are called the tamping tool that utility model patent provided of " the portable internal combustion high frequency tamping tool that has reducing gear ", and (3) application number is that " 200710180544.0 ", name are called " the eccentric tamping pickaxe that has self-lubricating function " tamping pickaxe that patent of invention provided, though the tamping result of these three kinds of tamping pickaxes is good; But all adopt the flexible axle transferring power; Its application life is short, and flexible axle is in rotation process simultaneously, and flexible generation is vibrated; Influence the work of gasoline engine, also uncomfortable during operating grip.
The utility model content
The technical problem that the utility model will solve is that the flexible axle of existing tamping pickaxe is fragile, bending produced power when flexible axle rotated, and a kind of tamping pickaxe of torsion spring transferring power is provided, and made tamping pickaxe more durable, operated more comfortable.
The technical scheme of the utility model realizes in the following manner: a kind of tamping pickaxe of torsion spring transferring power, comprise handle, drive unit and vibrating head, between drive unit and the vibrating head tapper torsion spring is set, torsion spring by bearings in sleeve pipe.
At least two torsion springs are set between said drive unit and the vibrating head, are provided with the torsion spring reference column between adjacent two torsion springs, the torsion spring reference column by bearings in sleeve pipe.
At least two torsion springs are set between said drive unit and the vibrating head, and linking to each other is provided with power transmission shaft between two torsion springs, and bearings is passed through in sleeve pipe in the power transmission shaft two ends.
Said torsion spring is the cylinder torsion spring, and the bending of torsion spring termination is cross bar, and cross bar is inserted in the cell body of torsion spring reference column.
The utility model is provided with torsion spring between drive unit and vibrating head tapper; Compared with prior art; Need not use flexible axle to connect drive unit and vibrating head; Use torsion spring instead drive unit is connected with the vibrating head tapper, crooked vibrative problem when having overcome flexible axle weak point in application life, flexible axle rotation.

The specific embodiment
Embodiment 1: present embodiment comprises handle 31, drive unit and vibrating head, and two torsion springs are set between said drive unit and the vibrating head, is provided with power transmission shaft between adjacent two torsion springs, and bearings is passed through in sleeve pipe in the power transmission shaft two ends.The present embodiment concrete structure is following: in casing 26, the power source of said drive unit is a gasoline engine 21 to the output shaft 33 of drive unit by bearings, and output shaft 33 and first plays torsion spring reference column 19 screw threads and links to each other; First plays torsion spring reference column 19 links to each other with first torsion spring, 18 upper ends, and first torsion spring, 18 lower ends and the 3rd play torsion spring reference column 17-1 and link to each other, and said the 3rd torsion spring reference column 17-1 links to each other with power transmission shaft 14 screw threads; Power transmission shaft 14 links to each other with the 4th torsion spring reference column 52 screw threads; The vertebra 103 that rolls that is provided with second torsion spring, 11, the second torsion spring reference columns 10 and vibrating head 1 between the 4th torsion spring reference column 52 and the second torsion spring reference column 10 links to each other, and power transmission shaft 14 two ends are by bearings; The upper end bearing is located in the sleeve pipe 15; The bearing of lower end is located in the adapter sleeve 12, and adapter sleeve 12 1 ends link to each other with vibrating head 1 shell, and the other end links to each other with sleeve pipe 15.
Said first torsion spring 18 is cylinder torsion springs, and the two ends bending of cylinder torsion spring is cross bar 18-1, and cross bar 18-1 is separately positioned in the torsion spring reference column locating slot 100, and the structure of each torsion spring is identical.
Present embodiment adopts two torsion springs to roll vertebra 103 with what the transmission of power of drive unit output shaft was given vibrating head, its long service life, and torsion spring can play certain damping effect.
Embodiment 2: shown in the figure accompanying drawing, a kind of tamping pickaxe of torsion spring transferring power comprises handle, drive unit and vibrating head 1, between drive unit and the vibrating head tapper torsion spring is set.
Three torsion springs are set between said drive unit of present embodiment and the vibrating head, are provided with the torsion spring reference column between adjacent two torsion springs, the torsion spring reference column by bearings in sleeve pipe 15.Its concrete connected mode is following: the output shaft 33 of drive unit by bearings in casing 26; The power source of said drive unit is a gasoline engine 21; Output shaft 33 links to each other with the first torsion spring reference column, 19 screw threads, and the first torsion spring reference column 19 links to each other with first torsion spring, 18 upper ends, and first torsion spring, 18 lower ends link to each other with the middle torsion spring reference column 17 in a left side; Torsion spring reference column 17 links to each other with middle torsion spring 101 1 ends in the middle of the left side; Middle torsion spring 101 other ends link to each other with right middle torsion spring reference column 102, and the vertebra 103 that rolls that is provided with second torsion spring, 11, the second torsion spring reference columns 10 and vibrating head 1 between the right middle torsion spring reference column 102 and the second torsion spring reference column 10 links to each other.Torsion spring reference column 17 and right middle torsion spring reference column 102 are by bearings in the middle of the left side.
Said first torsion spring 18 is cylinder torsion springs, and the two ends bending of cylinder torsion spring is cross bar 18-1, and cross bar 18-1 is separately positioned in the torsion spring reference column locating slot 100, and the structure of each torsion spring is identical.Only be provided with a locating slot on the first torsion spring reference column and the second torsion spring reference column, and the both sides of the middle torsion spring reference column 102 of the torsion spring reference column 17 and the right side all are provided with locating slot in the middle of the left side.
Present embodiment adopts three torsion springs to roll vertebra 103 with what the transmission of power of drive unit output shaft was given vibrating head 1, can play certain damping effect.
