The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

The embodiment provides a mechanized equipment of vibrating for track bed concrete construction, please refer to fig. 1 and fig. 2, including frame 1 that the bottom is equipped with the walking portion, be equipped with drive division and vibration portion on frame 1, the drive division includes chain 2 and sprocket 3 through motor 4 driven, vibration portion is including fixing crossbeam 5 on chain 2 and fixing the vibrating rod 6 on crossbeam 5, crossbeam 5 drives and is elevating movement through chain 2, is equipped with counter weight portion 7 on crossbeam 5, motor 4 is servo motor 4.

In the above embodiment, the frame 1 serves as a main structure of the whole apparatus for supporting and connecting the whole apparatus. The frame 1 can be formed by assembling and welding aluminum alloy sections and plates with thin-wall large square tube structures, has light weight and good bearing capacity, and can reduce the weight of the whole machine which is added when the whole machine walks on the track panel double tracks.

The walking part can be composed of two groups of worm and gear speed reducers 9 and four groups of special wheel trains for the tracks. Four sets of special wheel trains for the rails are arranged at the bottom of the front end and the rear end of the frame 1 and are symmetrically distributed, two sets of speed reducers 9 are respectively and correspondingly arranged on the two sets of special wheel trains at the rear part to form an active walking mechanism, the two sets of special wheel trains at the front part form a passive walking mechanism, and the four sets of wheel trains walk along the tool rails arranged in rows.

In the above embodiment, the driving portion is a chain transmission flexible lifting system composed of a chain 2 and a chain wheel 3, power is provided by a motor 4, the motor 4 realizes the lifting of the cross beam 5 through positive and negative rotation, namely the chain 2 is tensioned and lifted upwards when the cross beam 5 is lifted, the chain 2 is loosened when the cross beam 5 is lowered, the cross beam 5 falls under the action of self weight and the gravity of the counterweight portion 7, and the vibrating rod 6 can ascend and descend in such a cycle. The motor 4 is a servo motor 4, the rotating speed of which can be adjusted, so that the lifting speed of the cross beam 5 can be adjusted, and the vibrating rod 6 can be quickly inserted downwards and slowly lifted upwards so as to follow the principle of 'quick insertion and slow pull' of concrete vibration.

It should be noted that, in the lifting process of the beam 5, the rotation speed of the servo motor 4 is relatively slow, so that the beam 5 can be lifted upwards stably and slowly, and in the descending process of the beam 5, the rotation speed of the servo motor 4 is relatively fast, the pulling force between the chain 2 and the beam 5 disappears, that is, the chain 2 is in a relaxed state, and the beam 5 falls under the action of the self weight and the gravity of the counterweight part 7, so that the vibrating rod 6 is rapidly inserted into the concrete.
