Background
The dynamic rammer is one of special equipments in foundation construction of modern building, and the method for ramming foundation by using dynamic rammer is called power consolidation method, and it uses lifting equipment to repeatedly lift 80-2000kN hammer to 8-40 m height, then utilizes automatic unhooking to release load or free fall with hammer, and its kinetic energy can form strong shock wave and high stress in the soil so as to raise foundation strength, reduce compressibility, improve its ability of resisting vibration liquefaction and eliminate wet-sinking property. The construction of the dynamic consolidation method and the dynamic compaction machine are closely linked, and the progress, safety and benefit of the dynamic compaction project and the development of the dynamic compaction process are directly influenced by the quality of the working performance and the construction capacity of the dynamic compaction machine. The equipment performance of the dynamic compaction machine has the following requirements: (1) the dynamic compactor has a higher working level which is not lower than A7; (2) the dynamic compactor has stronger terrain adaptability and higher operation stability; (3) the power of the engine should be sufficient, and the walking mechanism can adapt to walking and steering on muddy and sunk ground; (4) the hoisting mechanism has wide width, high capacity, high elastic output performance and high braking capacity; (5) the influences of deformation of the arm support and deformation energy storage of the flexible variable auxiliary system can be effectively inhibited.
In a word, the dynamic compaction machine is engineering equipment with high requirements on a mechanical system, a power system, a hydraulic system and an electrical system. The dynamic compaction machine mainly relates to a power system, a hydraulic system and an electric system of the dynamic compaction machine, and is effective integration and high fusion of three technologies.
The operation mode of the dynamic compaction machine in the market at present is as follows: after an operator starts an engine (a power source), the speed of the working mechanism of the dynamic compactor is controlled by pushing the pilot handle to control the speed of the rotating speed of the hydraulic pump. Because the power of the pump comes from the engine, the operator needs to operate the accelerator according to the load of the hydraulic pump so as to ensure that the output power of the engine can follow the power required by the hydraulic pump. This way of manipulation has three drawbacks: 1. the labor intensity of the operator is high: pushing a pilot handle by hand, stepping on an electronic accelerator by feet, and using hands and feet by an operator; 2. the requirements on the experience of the operator are high: the electronic throttle and the pilot handle are controlled only by being combined at the same time, so that the maximum benefit of the equipment can be exerted, which is often determined by the experience of an operator; 3. the equipment is greatly influenced by the irregular operation of an operator, and the irregular operation causes high oil consumption and low efficiency.
