Abstract

The utility model relates to a small-sized railway maintenance device, in particular to a portable impact pickaxe, which comprises a petrol engine, wherein a casing on one side of the petrol engine is fixedly connected with a bearing support on the petrol engine, an output shaft of the petrol engine is threaded in the casing and is fixedly connected with a pinion which is meshed and connected with a bull gear which is fixed on a gear cover through a bearing, the bull gear and the upper end of a crank are moveably and eccentrically connected, the gear cover and the casing are connected through screw threads, a cylinder is fixedly connected on the central portion inside the casing, a drive piston on the upper portion of the cylinder is fixedly connected with the lower end of the crank, the lower end of a piston rod on the lower portion of the cylinder is opposite to the upper end of a pickaxe head, the pickaxe head is clamped in a pickaxe sleeve under the casing through a spacing card, one ends of handles on two sides of the casing are connected with the upper portion of the outside of the casing through a hinge, and the other ends are fixedly connected with the outside of the casing through a damping spring. The portable impact pickaxe has the advantages of compact structure, light weight, excellent property and high working efficiency.

Description

A kind of portable impacting pickaxe

Technical field:

The utility model relates to a kind of small-sized m of w equipment, especially a kind of portable impacting pickaxe.

Background technology:

Small-sized tamping machine is the facility of extensive use in the rail track maintenance work.At present the impact type tamping tool complete machine weight of using is bigger, and impact force is little, and tamping result is poor, and the handgrip vibration force is bigger during operation, the work effort.

The utility model content:

The utility model provides a kind of portable impacting pickaxe, and its compact conformation is in light weight, and performance is good, and the operating efficiency height has solved problems of the prior art.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises gasoline engine, the casing of gasoline engine one side and the bearing support on the gasoline engine are connected, the output shaft of gasoline engine penetrates casing and pinion is connected, pinion be connected with a joggle by the gear wheel of bearing fixing on gear cap, gear wheel and movable eccentric connection of crank upper end, gear cap is threaded with casing; The middle part is fixed with cylinder in casing, and the driven plunger on cylinder top and crank lower end are connected, and the piston-rod lower end of cylinder bottom is relative with the pick upper end position, and pick is installed in the pick cover of casing bottom by spacing card; Handgrip one end of casing both sides is connected with casing outer upper hinge, and the other end is connected by the shock-absorbing spring and the casing outside.

The upper end is wider than in described pick bottom, is tabular.

The utility model adopts said structure, has following advantage:

1, compact conformation, complete machine is in light weight, and is easy to operate;

2, adopt Pneumatic pressure power to learn principle, it is big to make impact force firm by ramming, impacts steadily, and tamping result is good;

3, handgrip adopts shock-absorbing spring to be connected with casing, the vibration force when having alleviated work widely, and it is laborsaving to work;

4, the upper end is wider than in the pick bottom, is offset flat shape, and speed is made in the following slotting and raising that helps pick during work firm by ramming, improves operating efficiency.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the left view of Fig. 1.

Among the figure, 1, gasoline engine; 2, casing; 3, pinion; 4, gear cap; 5, gear wheel; 6, crank; 7, cylinder; 8, driven plunger; 9, piston rod; 10, pick; 11, spacing card; 12, pick cover; 13, handle; 14, shock-absorbing spring.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

Shown in Fig. 1～2, the utility model comprises gasoline engine 1, the casing 2 of gasoline engine 1 one sides is connected with the bearing support on the gasoline engine 1, the output shaft of gasoline engine 1 penetrates casing 2 and is connected with pinion 3, pinion 3 be connected with a joggle by the gear wheel 5 of bearing fixing on gear cap 4, gear wheel 5 and movable eccentric connection of crank 6 upper ends, gear cap 4 is threaded with casing 2; The middle part is fixed with cylinder 7 in casing 2, and the driven plunger 8 and crank 6 lower ends on cylinder 7 tops are connected, and piston rod 9 lower ends of cylinder 7 bottoms are relative with pick 10 upper end positions, and pick 10 is installed in the pick cover 12 of casing 2 bottoms by spacing card 11; Handgrip 13 1 ends of casing 2 both sides are connected with casing 2 outer upper hinges, and the other end is connected by the shock-absorbing spring 14 and casing 2 outsides.

The upper end is wider than in described pick 10 bottoms, is tabular.

When operation, start gasoline engine 1, the output shaft of gasoline engine 1 drives pinion 3 rotations, pinion 3 drives gear wheel 5 rotations, gear wheel 5 is by reciprocating in cylinder 7 with its movable eccentric crank that is connected 6 drive driven plunger 8, and the reciprocating motion of driven plunger 8 in cylinder 7 compressed the gas in the cylinder 7 repeatedly, moves back and forth thereby promote piston rod 9, it is reciprocating that piston rod 9 moves back and forth the promotion below pick 10 relative with its position, thereby finish the tamping operation to ballast aggregate.After operation finishes, extinguish gasoline engine 1, complete machine is carried away the operation area get final product.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
