Description

Technical Field

[0002] Dynamic compaction primarily utilizes the impact and vibration of a rammer to complete the work. Rammers can be categorized as fire-powered, frog-type, and rapid-impact rammers. Dynamic compaction machines are a key type of compaction machinery in the construction industry, widely used in foundation treatment applications such as mountain blasting and silt filling, land reclamation, mountain backfilling, and airport construction. To improve data measurement accuracy, dynamic compaction machines are typically equipped with laser rangefinders above the rammers for data monitoring.

Due to the dust in the construction site, it is easy to cause dust pollution to the laser ranging sensor, affecting its use.

[0024] In this embodiment, a support ring 13 is fixedly provided on the upper end of the sealing cover 11, a rubber shock-absorbing block 10 is fixedly connected to the lower end surface of the top plate of the protective tube 8, and the laser ranging sensor 9 is arranged between the rubber shock-absorbing block 10 and the support ring 13. The rubber shock-absorbing block 10 realizes the shock-absorbing and buffering function of the laser ranging sensor 9, thereby improving its stability during use.

[0025] In this embodiment, a connecting shaft 14 is rotatably provided on the lower end surface of the mounting frame 7, and a driving disk 16 is fixedly connected to the rear end of the connecting shaft 14. A connecting rod 17 is rotatably connected to one side of the outer wall of the driving disk 16, and a connecting rod 17 is rotatably connected to the other end of the connecting rod 17. A connecting rod 2 18 is rotatably connected to the other end of the connecting rod 18. A piston 19 is fixedly connected to the other end of the connecting rod 2 18. The piston 19 is movably sleeved in the air cylinder 20, and is driven to reciprocate in the air cylinder 20 by the rotation of the driving disk 16 and the connection between the connecting rod 17 and the connecting rod 2 18.

[0026] In this embodiment, the front ends of the mounting shaft 5 and the connecting shaft 14 are sleeved with a synchronization mechanism 15. The synchronization mechanism 15 includes two synchronization wheels and a synchronization belt sleeved on the outer walls of the two synchronization wheels. The synchronization belt is engaged with the two synchronization wheels. The two synchronization wheels are fixedly sleeved on the outer walls of the mounting shaft 5 and the connecting shaft 14 respectively. By synchronously driving the two synchronization wheels to rotate at the same time, the connecting shaft 14 can be driven to rotate when the mounting shaft 5 rotates.

[0027] In this embodiment, a one-way valve 22 is rotatably connected to the air cylinder 20 and the air outlet pipe 21.

The blown gas passes over the lower end surface of the optical glass 12, removes the dust adhering to its surface, improves the cleanliness, and avoids affecting the use of the laser distance sensor 9. At the same time, the rubber shock-absorbing block 10 provided can provide shock absorption and buffering for the use of the laser distance sensor 9, thereby improving its stability during use.
