Technical Field
[0001] The utility model belongs to the technical field of dynamic probers, and in particular relates to a dynamic prober for geological exploration. Background Art
[0002] The dynamic penetration instrument is a kind of instrument that gives a certain impact to the rod column, so that the cone head enters the soil layer at a certain speed, and at the same time measures the resistance and number of impacts into the soil layer, thereby obtaining the physical properties of the soil layer. Geological and geotechnical exploration is a key link to ensure engineering safety, and the dynamic penetration instrument, as an exploration equipment, plays an irreplaceable role in geological and geotechnical exploration. It can provide accurate data for the evaluation of the properties of rock and soil, and is an indispensable and important tool in geological and geotechnical exploration.
[0003] At present, the methods of lifting the drop hammer of the dynamic probe mainly include manual and electric methods. Among them, manual lifting of the drop hammer usually relies on the operator to manually operate the lifting of the drop hammer. It is more practical in small projects or when the site conditions are relatively simple. No additional electric equipment is required, which reduces the cost investment. In contrast, the electric lifting method of the drop hammer has higher efficiency and accuracy. It uses electric equipment such as motors or hydraulic devices to achieve the lifting and release of the drop hammer, thereby greatly improving the work efficiency. Suitable for large projects or occasions that require continuous operation, the electric lifting method can significantly reduce manpower input and reduce labor intensity. However, at present, since many geological and geotechnical exploration points are uneven ground that has not been leveled, the hammer rod is easy to tilt, and the force of the drop hammer falling to hit the hammer seat is not concentrated; and whether the probe that lifts the drop hammer is manually or electrically, its design mostly relies on the top rod of the hammer rod to guide the falling path of the drop hammer. However, due to the different degrees of inclination of the hammer rod, it is very easy to affect the falling speed of the drop hammer during free fall and the impact force on the hammer seat after it falls, resulting in certain errors in the measurement data. Therefore, the utility model provides a dynamic probe for geological exploration, which is used for leveling uneven ground to ensure that the hammer rod is perpendicular to the ground and avoid the situation where the force of the hammer seat is not concentrated when the hammer falls.
