Product Description
operating principle
The hydraulic tamper of an excavator is connected to the hydraulic system of the excavator through the hydraulic pipeline of the excavator, and the hydraulic pump of the excavator provides high-pressure oil. When the control handle is operated, hydraulic oil enters the hydraulic motor or hydraulic cylinder of the tamper to drive the internal rammer assembly to move up and down reciprocally. Under the combined action of gravity and hydraulic power, the rammer impacts the ground with high speed and force, thereby realizing the tamping effect on the ground.
structural features
Shell and connection parts: Welded with high-strength steel plates, it has good rigidity and impact resistance and can withstand the huge reaction force during tamping. The connection part with the excavator is designed with a special connection seat and pin shaft to ensure firm and reliable installation and convenient disassembly and replacement.
Hammer assembly: The rammer is generally forged from high-quality alloy steel. Its shape is mostly cylindrical or cuboid. Its quality and shape are carefully designed to ensure the tamping effect and energy transfer efficiency. The rammer is connected to the piston rod or transmission mechanism through a special connection method to ensure that it will not loosen or fall off during the high-frequency tamping process.
Hydraulic system: The built-in hydraulic motor or hydraulic cylinder is the core power component of the tamper. It has a high working pressure and flow capacity, and can quickly respond to the instructions of the hydraulic control system to realize the stable reciprocating movement of the rammer. At the same time, it is equipped with an advanced hydraulic control valve group, which can adjust the tamping frequency and intensity according to the actual operation needs.
application scenarios
Road Engineering: In road base construction, layered compaction is carried out on filled soil and rock embankments to improve the overall strength and stability of the roadbed and reduce settlement and deformation of the road in the later stage. In road widening and renovation projects, compaction treatment is carried out on the joint part of the new and old roadbeds to ensure good connection between the new and old roadbeds.
Railway engineering: Used for filling and strengthening railway subgrades. It compacts the subgrade soil below the ballast bed to improve the compactness of the subgrade, providing a solid foundation for the laying of railway tracks and ensuring the safety and smoothness of train operation.
Construction Engineering: In building foundation treatment, compact and strengthen the weak foundation to improve the bearing capacity of the foundation and meet the requirements of the building for the foundation. In the backfilling soil construction of foundation pits and trenches, compact the backfilling soil to avoid problems such as foundation subsidence caused by uncompacted backfilling soil.
Our Advantages
performance advantages
Good compaction effect: Compared with traditional manual compaction or small compaction equipment, the excavator hydraulic tamper has greater ramming energy and higher ramming frequency. It can make the foundation materials reach a higher density in a short time and effectively improve the bearing capacity and stability of the foundation.
High operation efficiency: With the maneuverability and flexibility of excavators, hydraulic tampers can quickly move to different operation positions without manual handling or frequent adjustment of equipment, greatly improving construction efficiency and saving labor and time costs.
Wide application range: It can be widely used in various foundation engineering compaction operations, such as road construction, railway subgrade construction, airport runway construction, port and wharf construction, building foundation treatment, etc. It has good compaction effects on different types of soil and foundation materials.
