Embodiment Construction
[0029] The present invention will be further described below in conjunction with specific embodiments and drawings.
[0030] see Figure 1 to Figure 6 As shown, the present invention is a new type of electric tamping machine, which includes: a high-pressure cylinder 1, a grip 2, a motor 4, a reduction gear box 5, a cam 10, an impact hammer 12 and a pick 6.
[0031] Combine Image 6 As shown, the high-pressure cylinder 1 is located at the uppermost end of the entire tamping machine and includes: a closed cylinder filled with high-pressure gas, and a piston 7 arranged in the cylinder of the high-pressure cylinder 1 and capable of reciprocating movement in the cylinder. , A piston rod 15 fixedly connected to the piston 7 and extending downward. The high-pressure gas filled in the cylinder of the high-pressure cylinder 1, under the pressure of this high-pressure gas, and without external force, the piston 7 is pressed by the high-pressure gas at the lowest end of the cylinder, and pas...

The invention discloses a novel electric tamping machine which comprises a high-pressure air cylinder, a cam, an impact hammer and a pick drill rod. The cam is driven by a motor to rotate and pushes aguide rod to move upwards, the guide rod acts on a piston rod, and a piston is pushed to move upwards to further compress compressed gas in a cylinder block; and after the cam crosses an interferencepart, the guide rod loses upward acting force, high-pressure gas in the cylinder block pushes the piston to move downwards, and the guide rod and the impact hammer are pushed to act on the pick drillrod to knock the pick drill rod. The high-pressure gas is used for storing energy, the cam rotates to push the piston to further compress the compressed gas in the high-pressure air cylinder to act,the cam instantaneously releases the piston in the rotating process, and the piston and the impact hammer are pushed by the high-pressure gas to move in the direction opposite to compression of the high-pressure air cylinder at a high speed. The novel electric tamping machine has the beneficial effects of being high in efficiency, small in noise, high in energy density, light in weight, small in size and the like.
Description
Technical field: [0001] The invention relates to the technical field of electric tools, in particular to a new electric tamping machine using compressed air as a power source. Background technique: [0002] Electric tamping machine is commonly known as electric pick. At present, the traditional tamping machine adopts the following structure: the rotation of the motor drives the crank to rotate, the rotation of the crank drives the gas piston to reciprocate; the other slave piston also follows the main gas piston under pressure Do reciprocating motion; the driven piston is connected with the impact hammer, and the impact hammer strikes the pick to achieve the effect of tamping. The disadvantages of this structure are: [0003] 1. The driven piston does work under the driving force or traction force generated by the air pressure change generated during the reciprocating motion of the main piston, and its work efficiency is very low. [0004] 2. Due to the heavy weight of the driven p...
