In addition, with the continuous high-speed development of national economy in China, a large number of tunnels are required to be constructed for railways, highways, hydraulic engineering and the like, concrete secondary lining operation must be carried out in the tunnel construction process, and the concrete lining trolley is indispensable equipment in the tunnel construction secondary lining process. The concrete lining trolley mainly comprises a simple lining trolley, a full-hydraulic automatic walking lining trolley, a net frame type lining trolley and the like at present, and a concrete vibrator is used for vibrating and compacting no matter which type of concrete lining trolley is used after concrete secondary lining so as to ensure the compaction of a concrete structure and the quality of the secondary lining.
Disclosure of Invention
The invention aims to innovatively develop an air motor driven plug-in vibrator to meet the urgent need of concrete construction of a tunnel lining trolley.
The technical scheme of the invention is as follows: an air motor at the left end of the vibrator is fixed on an air motor flange, and an air motor joint is connected with the air motor; the four uniformly distributed rubber springs are fixed on the spring clamping plate, the left end of the air motor joint is connected with a spring positioning column, the spring positioning column is connected with a torsional spring, and the left end of the torsional spring is connected with the spring positioning column; the left end of the connecting sleeve is connected with the spring clamping plate, the right end of the connecting sleeve is connected with the rod body, and the left end of the rod body is connected with the tip; the left end of the spring positioning column is connected with a joint, the right end of the joint is connected with an eccentric shaft, and the eccentric shaft is supported on bearings at two ends of the rod body.
